The present invention relates to a gaming machine having a re-drawing function. Moreover, the present invention relates to a gaming machine that is installed in a casino or the like, and in particular conducts a slot game. In addition, the present invention relates to gaming machines for the playing of games of chance and, more particularly, to special features of games or feature games which may be offered on such machines.
Conventionally, there are known pachinko-type gaming machines comprising slot machine and reel units that carry out re-drawing. For example, in the pachinko gaming machine disclosed in Publication of Japanese Patent No. 3330338, when a player operates a hitting handle, pachinko balls are hit into a game region formed in a front surface of a game board one by one. A reel unit that can change display or stop display of a plurality of symbols, and a plurality of starting winning holes are provided on the play surface. In a case where a pachinko ball goes into any of the starting winning holes, the pachinko ball is detected by a starting winning ball detector, and each reel in the reel unit rotates based on a detection signal of the starting winning ball detector, so as to change display the plurality of symbols. After a predetermined time has passed, a second reel (center reel) stops, and in a case where the second reel that stops is a symbol other than a specific symbol, a first reel (left reel) stops thereafter, and finally, a third reel (right reel) stops. When every reel stops, in a case where a combination of pre-set specific symbols are displayed, a situation favorable for the player occurs by for example, opening an opening/closing plate of a variable prize winning ball device in a tulip-shape, and creating a situation where a predetermined game value can be provided to the player.
Each reel can display three symbols in the longitudinal direction. Therefore, symbols displayed by the three reels are in a 3×3 matrix alignment. In this matrix, a total of five lines are formed: three horizontal lines and two diagonal lines.
On the other hand, in a case where a symbol stop displayed is a specified symbol (for example “7”) at the time the second reel stops, the change display discussed below is carried out. The first and third reels continue change display of the symbols, but the first and third reels are stopped at the same time, or are stopped in an order of first reel, then the third reel, after slowly rotating the “7” symbol horizontally, downwards, or upwards, in a state where the symbols are matched. By this, a situation where a matching is possible in a win line of a center horizontal direction, a win line of a downward direction, or win line of an upwards direction is possible, while the rotation of the first and third reels.
However, in the conventional re-drawing method, it is difficult to correspond to a slot machine with many reels, or a slot machine that validates a plurality of symbols on one reel. In the conventional method, when a predetermined condition is met, re-drawing is carried out by the entire reels, so as to standardize variation of re-drawing.
Gaming machines such as slot machines, poker machines, fruit machines, and the like generally attract enormous popularity from players in casinos. Such a gaming machine displays an arrangement of symbols on the front thereof, and randomly changes types of symbols in the arrangement at each round of game. A player places a bet at the start of each round. If a winning combination appears in the arrangement, the player will win an amount of a payout that depends on the amount of the bet and the type of the winning combination.
This type of gaming machine is generally equipped with mechanical reels that are coaxially arranged and allowed to independently spin by respective motors. Symbols are permanently displayed, e.g., printed on the circumferential surfaces on each reel in a predetermined order. Mechanical reels repeat spins and stops, and thereby change visible symbols at random. Alternatively, this type of gaming machine may use an electric display device to display symbols in graphic form on a screen thereof. The symbols are aligned in two or more columns, i.e., video reels Like mechanical reels repeating spins and stops, video reels repeatedly change in appearance, and thereby symbols repeatedly move and stop in a vertical direction. Such actions of symbols are often referred to as “spins and stops of video reels”. There is also a mechanical reel with one or more electric display devices mounted on the circumferential surface of the mechanical reel. Symbols are displayed in graphic form on a screen of the electric display device. Visible symbols move and change, whichever the mechanical reel spins or the electric display device changes images produced thereon.
Most players prefer a gaming machine that can provide a larger amount of payout. The upper limit of payout per round generally depends on a total number of types of symbol arrangements visible on reels. Mechanical reels have a limited number of symbol types mainly because of their sizes. In order to increase the upper limit of payout per round, a gaming machine with mechanical reels randomly provides a player with a right to play a bonus round. A player can win a larger amount of payout, or an amount of payout more frequently at a bonus round than at a normal round. In addition, a player can play a bonus round for free.
On the other hand, video reels have no limited number of symbol types in principle. However, a gaming machine with video reels also provides a player with a right to play a bonus round in order to enhance the variety of game contents and visual effects, and thereby attract a larger number of players.
Recent remarkable progress on game controllers, computer graphics, and display devices enables gaming machines to produce more various types of bonus rounds with more complex rules and visual effects. This facilitates differentiation of a type of gaming machines from others. On the other hand, excessively complex rules and visual effects may prevent gaming machines to raise players' expectations for winning In addition, excessively complex rules and visual effects may place a heavy burden on game designers and developers.
In addition, traditionally such gaming machines were mechanical devices where a number of reels marked with a plurality of numbers or symbols could be made to spin randomly by the application of some mechanical input. If the subsequent patterns of numbers or symbols displayed on the reels, when these returned to a rest state, corresponded to predetermined patterns, the machine would provide a prize or payout. Generally such gaming machines have come to be regulated by government authorities as to their number and in the manner in which the machines must return a percentage of the monetary turnover to the players.
The introduction of electronics, computers and electronic graphical displays, has allowed a continual increase in the complexity and variations of gaming machines, games and displays while maintaining the basic concept of the traditional machine. Nevertheless, in some jurisdictions at least, government regulations effectively restrict the degree of variation which may be incorporated in games played on coin-freed machines.
Machines and games therefore that offer novel and stimulating variations on the basic game theme and environment, yet comply with these restrictions are eagerly sought by the gaming industry and there is consequently intense competition between machine manufacturers to innovate.
Games based on simulated rotatable reels typically display a matrix of elements each of which displays a symbol. Predetermined patterns of symbols, if displayed after the reels are spun and come to rest, may then award a prize to the player of the game. Typically also, the symbols are arranged in the elements of a reel so that adjoining elements do not display the same symbol.
An exception to this is found for example in Australian Patent Application number 2004203045 (Aristocrat Technologies Australia Pty Ltd), in which arrangements are envisaged where two special symbols may occur adjacent one to the other.
A similar exception is found in Australian Patent Application number 2002301067 (Stargames Corporation Limited), in which a specific symbol and the number of its occurrences in the display at the conclusion of a game sequence, is determinant of a win. As indicated in
Both these examples of the prior art allow for only a single predetermined or special symbol to take up such adjacent positions on a reel.
In view of the above, it will be apparent to those skilled in the art from this disclosure that there exists a need for an improved gaming machine that can produce a bonus round with more simple rules and visual effects, and thereby cause a player to recognize the bonus round more clearly and reduce a burden on game designers and developers. This invention addresses this need in the art as well as other needs, which will become apparent to those skilled in the art from this disclosure.
In view of the above-noted disadvantages, one of one of the objects of the present invention is to provide a gaming machine that can raise a player's interest in a game by carrying out diverse re-drawing in accordance with progress of the game.
In one aspect of the present invention, a gaming machine for providing a game to a player is provided. The gaming machine includes a display device for displaying the game and a game controller. The game includes a plurality of reels having a predetermined number of elements, wherein each element has an associated symbol from a set of symbols and at least one reel has a run of consecutive elements. The game controller initiates an instance of the game, responsively displays the game on the display device, randomly determines an outcome of the game, and responsively spins and stops the reels to display the outcome. The outcome includes at least two reels having the same symbols being displayed in the same symbol positions. The game controller displays each one of the at least two reels having a run of consecutive elements, and populates the run of consecutive elements with an identical symbol.
In another aspect of the present invention, a gaming machine for providing a game to a player is provided. The gaming machine includes a game controller and a display device for displaying the game including a plurality of reels. Each reel has a predetermined number of elements, wherein each element has an associated symbol from a set of symbols. At least one reel has a run of consecutive elements. The game controller initiates a first instance of the game and responsively displays the game on the display device, wherein the game includes a plurality of first reels and a second reel. The game controller detects a triggering condition in the first instance and in response to detecting the triggering condition, initiates a second instance of the game, determines an outcome of the second instance of the game including at least two first reels having the same symbols being displayed in the same symbol positions, displays the outcome including spinning and stopping the at least two first reels and retains a second reel in a stop position while the at least two reels are spinning.
In a further aspect of the present invention, a method of providing a game on a gaming machine is provided. The gaming machine has a plurality of reels and a display device. Each reel has a predetermined number of elements, wherein each element has an associated symbol from a set of symbols. At least one reel of the plurality of reels has a run of consecutive elements. The method includes initiating an instance of the game and responsively displaying the game on a display device, randomly determining an outcome of the game and responsively spinning and stopping the reels to display the outcome, wherein the outcome includes at least two reels having the same symbols being displayed in the same symbol positions, displaying each one of the at least two reels having a run of consecutive elements, and populating the run of consecutive elements with an identical symbol.
In another aspect of the present invention, a method of providing an electronic game on a gaming machine is provided. The gaming machine has a plurality of reels and a display device. Each reel has a predetermined number of elements, wherein each element has an associated symbol from a set of symbols. The method includes initiating a first instance of the game and responsively displaying the game on a display device, wherein the game includes a plurality of first reels and a second reel, detecting a triggering condition in the first instance and in response to detecting the triggering condition, initiating a second instance of the game, determining an outcome of the second instance of the game including at least two first reels having the same symbols being displayed in the same symbol positions, displaying the outcome including spinning and stopping the at least two first reels and retaining a second reel in a stop position while the at least two reels are spinning, and awarding an award to the player as a function of the outcome.
A gaming machine has a display unit having a first display area adapted to displaying a plurality of types of symbols and a second display area adapted to displaying specific symbols that have specific interrelationships, a draw control unit that determines the specific symbols to display for a first game, wherein after the specific symbols are displayed in the first game, the draw control unit controls the display of the specific symbols in the second display area at determined times of subsequent the games, and determines areas in which the specific symbols are not displayed in the first display area and wherein the plurality of types of symbols displayed in the first display area are predetermined by the draw control unit as symbols that have no specific interrelationship.
In this way, in a case where a predetermined symbol is stopped in a plurality of display regions, the display regions that display the predetermined symbols are set as specific display regions. Because drawing at predetermined times of games after the first game is carried out from a plurality of types of symbols that are to be displayed, there is a specific relationship among the symbols in each game and the symbols having a predetermined relationship are displayed in the specific display region. By this, an independent drawing result (re-drawing result) which differs from the general display region, can be displayed in the specific display region. The display regions other than the specific display regions are set as general display regions. In the general display regions, because drawing is carried out from a plurality of types of symbols that are to be displayed without the symbols having a predetermined relationship, the general display regions and specific display regions are respectively independent and co-exist. Namely, re-drawing is not carried out using every region, but re-drawing result is displayed in the specific display regions, which are a part of the display regions, and in the region of a remaining part, ordinary drawing result is displayed. By this, because drawing results are displayed by two types of regions: the specific display regions and the ordinary display regions, existing, a new kind of game that arouses the player's interests can be realized. Every display region can become a specific display region, in accordance with the course of the game.
A gaming machine has a display unit that performs a flash display of symbols in which symbols are moved in a constant fashion in a plurality of display areas and subsequently stops movement of the symbols to display all or a portion of the symbols in a substantially stationary fashion, a draw control unit that determines specific symbols to be stopped in a specific display area for a first game, and wherein the specific symbols stopped in one of the display areas, are different types of the symbols from those in other display areas in a predetermined number of times after the specific symbols are displayed in the first game.
In this way, in a case where a predetermined symbol is stop displayed in a plurality of display regions, the display regions that stop display the predetermined symbols are set as specific display regions, and because drawing in a predetermined times of games after the first game is carried out from a plurality of types of symbols that are to be displayed, so that the symbols are displayed the same in each game, same symbols are displayed in the specific display region. By this, an independent re-drawing result which differs from the general display region can be displayed in the specific display region. The display regions other than the specific display regions are set as general display regions. In the general display regions, because drawing is carried out from a plurality of type of symbols that are to be displayed, so that symbols are independently displayed, the general display regions and specific display regions are respectively independent and co-exist. Namely, re-drawing is not carried out using every region, but re-drawing result is displayed in the specific display regions, which are a part of the display regions, and in the region of a remaining part, ordinary drawing result is displayed. By this, because drawing results are displayed by two types of regions: the specific display regions and the ordinary display regions, existing, a new kind of game that arouses the player's interests can be realized. Every display region can become a specific display region, in accordance with the course of the game.
The gaming machine has wherein when one of the symbols in the other display areas is the same type of symbol as displayed in the specific display area, the draw control unit changes the symbols in the other display areas to the specific symbols, and controls all of the specific symbols to be same type of the symbols in a predetermined number of times after modified.
In this way, in a case where a symbol to be displayed in whichever ordinary display region is the same symbol as the symbol that is to be displayed in the specific display region, because the ordinary display region that has drawn the same symbols as the symbol that is to be displayed in the specific display region is changed to the specific display region, in a predetermined number of feature games after the next time, the number of regions that structure the specific display region increases every time the same symbol is drawn in the ordinary display region. Then, because a drawing from a plurality of types of symbols is carried out so that a same symbol is stop displayed in every specific display region including the increased specific display region, the same symbol is stop displayed in the entire specific display region. By this, diverse re-drawing can be carried out in the specific display region. As a result, a strong impression is provided to the player, and it is possible to arouse the player's interest.
The gaming machine has wherein when the symbols in one of the other display areas are in a win situation, the draw control unit modifies one of the other display areas to another specific display area, modifies the symbols in the another specific display area to the specific symbols, and controls all of the specific symbols in the one of the other display areas, being same type of the symbols in a predetermined number of times after modified.
In this way, in a case where a symbol to be displayed in whichever ordinary display region adjacent to the specific display region is the same symbol as the symbol that is to be displayed in the specific display region, because the ordinary display region that is adjacent to the specific display region, and has drawn the same symbols as the symbol that is to be displayed in the specific display region is changed to the specific display region, in a predetermined number of feature games after the next time, the number of regions that structure the specific display region increases every time the same symbol is drawn in the ordinary display region that is adjacent to the specific display region. Then, because a drawing from a plurality of types of symbols is carried out so that a same symbol is stop displayed in every specific display region including the increased specific display region, the same symbol is stop displayed in the entire specific display region. By this, diverse re-drawing can be carried out in the specific display region. As a result, a strong impression is provided to the player, and it is possible to arouse the player's interest.
The gaming machine has wherein at least one of the other display areas is adjacent to the specific display area.
In this way, in a case where a win situation is established in whichever of a plurality of ordinary display regions, during a game of a predetermined number of times, because the ordinary display region that is to establish a win changes to another specific display region independent from the specific display region, the number of specific display regions increases every time a win situation is established in the ordinary display regions. Then, because a drawing from a plurality of types of symbols is carried out so that a same symbol is stop displayed in every specific display, the same symbol is stop displayed respectively in each specific display region, the same symbol is respectively stop displayed in each specific display region. By this, diverse re-drawing can be carried out in the specific display region. As a result, a strong impression is provided to the player, and it is possible to arouse the player's interest.
The gaming machine has wherein the win situation is established when special symbols are displayed in one of the other display areas.
In this way, in a case where a win situation is established in whichever of a plurality of ordinary display regions by a predetermined symbol being displayed, during a game of a predetermined number of times, because the ordinary display region that is to establish a win changes to another specific display region independent from the specific display region, the number of specific display regions increases every time a win situation is established in the ordinary display regions by a predetermined symbol being displayed. Then, because a drawing from a plurality of types of symbols is carried out so that a same symbol is stop displayed in every specific display, the same symbol is stop displayed respectively in each specific display region, the same symbol is respectively stop displayed in each specific display region. By this, diverse re-drawing can be carried out in the specific display region. As a result, a strong impression is provided to the player, and it is possible to arouse the player's interest.
The gaming machine has wherein the draw control unit controls all of the specific symbols in the specific display area and one of the other display areas, being same type of the 10 symbols in a predetermined number of times after modified.
By this structure, in a case where the symbol to be displayed in the specific display regions and the other specific display region are the same, drawing is carried out so that the same symbol is displayed in every specific display region. Namely, the specific display region and the other specific display region display the same symbols by combining, and becoming one specific display region. By this, diverse re-drawing can be carried out in the specific display region. For example, variation of the game activity can be possible by for example, increasing the dividend in accordance with the increase in number of the regions that constitute the specific display region, etc. As a result, the player's interests can be aroused.
A gaming machine has a display unit displaying a plurality of types of symbols, upon starting a game, a draw control unit predetermining a specific symbol display area where specific symbols that establish a plurality of specific prizes are displayed at predetermined times after starting the game, wherein the draw control unit selects the specific symbols for one of the plurality of specific prizes, from a prize group to which the one of the plurality of specific prizes belongs, and predetermines a general display area where other symbols are displayed, wherein the general display area displays the other symbols independently of the specific symbols in each game.
In this way, in a case where a predetermined symbol that establishes a specific win is stop displayed in a plurality of display regions, the display regions that stop display the predetermined symbols that establish a specific win are set as specific display regions in a predetermined times of games from the next game, and because drawing is carried out from a plurality of types of symbols that are to be displayed, so that which ever one win that is the same as a win group that the specific win group belongs to (the group to which the win belongs to) is established in each game, wins can be changed in each game, maintaining a win situation. By this, players feel intrigued, and can raise the player's interest towards the game. The display regions other than the specific display regions are set as general display regions. In the general display regions, because drawing is carried out from a plurality of type of symbols that are to be displayed, so that symbols are independently displayed, the general display regions and specific display regions are respectively independent and co-exist. Namely, re-drawing is not carried out using every region, but re-drawing result is displayed in the specific display regions, which are a part of the display regions, and in the region of a remaining part, ordinary drawing result is displayed. By this, because drawing results are displayed by two types of regions: the specific display regions and the ordinary display regions, existing, a new kind of game that arouses the player's interests can be realized. Every display region can become a specific display region, in accordance with the course of the game.
The gaming machine has wherein when one of the other symbols in the general display area adjacent to the specific display area is the same type of the specific symbols in the specific display area, the draw control unit modifies the general display area adjacent the specific display area correspond to the specific symbol display area, and controls all symbols in the specific symbol display area to establish a prize that belongs to different group from the one of the plurality of specific prizes.
In this way, in a case where a symbol to be displayed in whichever ordinary display region adjacent to the specific display region is the same symbol as the symbol that is to be displayed in the specific display region, because the ordinary display region that is adjacent to the specific display region, and has drawn the same symbols as the symbol that is to be displayed in the specific display region is changed to the specific display region, in a predetermined number of feature games after the next time, the number of regions that structure the specific display region increases every time the same symbol is drawn in the ordinary display region that is adjacent to the specific display region. Then, because a drawing from a plurality of types of symbols is carried out in every specific display region including the increased specific display region, so that at least one win among win groups different from win groups that the specific win belongs to in each game is established. Namely by the number of regions structuring the specific display region increasing, the grading of the wing groups are changed, and players alternate between hope and despair every time the number of regions increase. By this, it is possible to arouse the player's interests towards the game.
In another aspect, a gaming machine according to the present invention comprises a display unit, a console unit, a game controller unit, and a display controller unit.
The display unit is configured to display symbols in a plurality of columns. The display unit preferably arranges the symbols in the same order in two or more of the columns. The display unit is configured to spin and stop the columns of symbols.
The console unit is configured to accept instructions from a player. The instructions preferably indicate starting a round of game or placing a bet. The console unit is preferably configured to accept money from a player.
The game controller unit is configured to execute a game program, and thereby control the following functions of game. First, the game controller unit starts a round of game in response to an instruction accepted by the console unit. Here, the game controller unit preferably uses a portion of the money accepted by the console unit as a bet. The game controller unit may interpret the instruction to place a bet as a cue for starting a round of game. Second, the game controller unit determines an arrangement of symbols at random on a condition that symbols are arranged in the same order and at the same positions in the two or more columns. Third, the game controller unit retrieves a winning combination from the arrangement of symbols. Fourth, the game controller unit provides the player with an award depending on the winning combination retrieved from the arrangement of symbols. Here, the game controller unit may determine the type of the award depending on the bet.
The display controller unit is configured to cause the display unit to spin the two or more columns of symbols from the same position in synchronization with each other, and stop the two or more columns at the same position to display the arrangement of symbols determined by the game controller unit.
In general, a winning combination includes the same type of symbols at the same positions of two or more columns. Since the game controller unit determines an arrangement of symbols on the condition that symbols are arranged in the same order and at the same positions in two or more columns, chances are fairly good that a winning combination will appear in the arrangement determined by the game controller unit. Furthermore, the display unit spins the two or more columns of symbols from the same position in synchronization with each other. This effectively raises player's expectations for winning an award. On the other hand, the condition is easy to impose on the game controller unit. The display controller unit can easily control the two or more columns of symbols spinning in the above-mentioned synchronized manner. Thus, the gaming machine can provide a player with a better chance of winning an award in a simple manner, and cause the player to recognize the chance through simple and clear visual effects, without any heavy burden on game designers and developers.
Preferably, the display unit comprises a mechanical reel rotatable around its axis and having a circumferential surface on which a column of symbols is displayed. Alternatively, the display unit may comprise an electric display device on which a column of symbols is displayed in a graphic form. The electric display device may be mounted on the circumferential surface of a mechanical reel, and thereby rotatable together with the mechanical reel around the axis thereof.
The game controller unit preferably determines an arrangement of symbols at random without the above-mentioned condition in normal games, and on the condition in bonus games. In that case, the display controller unit preferably causes the display unit to spin all columns of symbols independently in normal games, and spin the two or more columns of symbols from the same position in synchronization with each other in bonus games.
The display unit preferably pairs a left end column of symbols with a right end column thereof in turn, starting from the outmost columns thereof, and arranges symbols in the same order in each pair of columns. In that case, the game controller unit preferably determines an arrangement of symbols at random on a condition that symbols are arranged in the same order and at the same positions in each pair of columns. Furthermore, the display controller unit preferably causes the display unit to spin each pair of columns from the same position in synchronization with each other, and stop the pairs at respective positions in the order from outermost to innermost. Note that the display controller unit may cause the display unit to stop the pairs in another order, e.g., from innermost to outermost, or at random. Alternatively, the display unit may pair different two columns, e.g., two adjacent columns or two columns separated by one other column.

These objects and other objects and advantages of the present invention will become more apparent upon reading of the following detailed description and the accompanying drawings in which:
Corresponding reference characters indicate corresponding parts throughout the drawings.
A selected embodiment of the present invention will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following description of the embodiment of the present invention is provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
(1) Definition of Re-Drawing Reel
The purpose of re-drawing is to maintain an established win situation or a situation where particular symbols appear on the reel. One example is a case where three “cherry” symbols match on a slot machine. In this case, a win situation of “three matches” is established. Re-drawing maintains this win situation, and switches the kind of desired symbol to, for example “bar”, and “7”, etc. Also, re-drawing is to carry out re-drawing of symbols, maintaining a situation where same symbols appear in every position of up, middle, and down of the first to third reels, or maintaining a situation where same symbols appear in positions of each column, assuming that re-drawing is carried out in the first to third reels, in a five-reel slot machine. It is possible that the original symbol is re-drawn. In the case of “in a case where predetermined symbols are displayed stopped to a plurality of display regions, in a predetermined number of games after that game, in special display regions where the predetermined symbols are displayed, in at least game units, drawing is carried out from a plurality of kinds of symbols that are to be displayed having a predetermined relationship among the symbols”, “predetermined relationship” corresponds to the above “established win situation, or a situation where symbols appear on the reels”.
(2) Re-Drawing Reel
The re-drawing reel is for carrying out the above-discussed re-drawing. Symbol alignment of the re-drawing reel are all the same. By aligning the symbol alignment in a same position, and by rotating or stopping the reels, synchronizing timing and speed, the win situation can be maintained, and re-drawing of symbols can be carried out. A group of a plurality of re-drawing reels that maintain a common win situation will be described as “re-drawing reel group”.
Appearance of the Re-Drawing Reel
Appearance of the re-drawing reel is switching of an ordinary reel to a re-drawing reel under a condition that a certain setting condition is established. This setting condition can be for example, appearance of a predetermined symbol. Below, this predetermined symbol will be described as a “trigger symbol”. Or, a situation where a predetermined win (for example “BAR-BAR-BAR” and “7-7-7”, etc.), being established by a combination of symbols, can be the “condition” of above. Or, in a case where a poker game is carried out, one establishment of the winning combinations, such as shown in
Increase of the Re-Drawing Reel
Increase of the re-drawing reel is carrying out the increase operation discussed, under the condition that some kind of setting condition is established. Here also, a predetermined symbol appearing, and a predetermined win situation being established by a combination of symbols, can be the setting condition. Also, for example, in a case where a poker game is carried out, one establishment of the winning combinations, such as shown in
1. Increase in number of the re-drawing reels included in the re-drawing reel group
2. Increase in number of the re-drawing reel group itself
Establishment of a win situation by a combination of a plurality of kinds of symbols may be the condition for the appearance of the re-drawing reel, or the increase of the re-drawing reel. For example, cases where combinations of symbols that express a specific meaning content, are displayed, such as “G” “0” “D” (GOD), and “C” “0” “I” “N” (COIN). The embodiments of the present invention will be described, with reference to the drawings.
As shown in
In
The reels that establish a win situation during a feature game is switched to a re-drawing reel, in a unit of a symbol according to the win situation. Therefore, each time a win situation occurs in the feature game, an independent new re-drawing reel is generated. A plurality of kinds of re-drawing reels independently rotate, and stop. However, in a case where a same symbol is displayed stopped in a plurality of kinds of re-drawing reels, those reels combine, and one re-drawing reel, wherein the number of reels is increased is generated. Below, the first embodiment will be described in detail.
As shown in
In front of the chassis 2, a medal (the medal may be real money, such as a coin) slot 10, and a medal return button 10a, which returns the medal, in a case where the inserted medal is stuck, etc. A start lever 11 is for carrying out starting operation of a rotating display (change display) of the symbol display unit 7.
A game in the gaming machine 1 starts by a player carrying out a BET operation. The BET operation is carried out by credits or by inserting money. As above, a medal or a coin can be used, as having an equivalent value as money. BET operation can be possible by providing a device that receives inserting of bills, and a card reader/writer. After BET operation by a player, when the start lever 11 is operated, the symbol display unit 7 change displays the symbols. After a predetermined time has passed, the symbol display unit 7 sequentially stop displays the change-displayed symbols. The order for stopping may be that every reel stops at once, or the reels may be stopped in an order from reel A1 to A9. In a case of sequentially stopping, the reels can be stopped having a time interval of for example 0.5 seconds. When three or more predetermined symbols are adjacent at this stopped state, a win situation corresponding to that symbol is obtained.
On the lower side of the front panel 3, a medal pay-off opening 15 and a medal receiving tray 16 is provided, and on the upper side of the front panel 3, a game rendition indicator 17, which is driven for • game rendition is provided. The game rendition indicator 17 comprises for example LCD (Liquid Crystal Device) or various types of lamps. In the first embodiment, an embodiment where LCD is adopted is shown. On the upper side of the front panel 3, a bonus game indicator 18 is provided. The bonus game indicator 18 comprises LED (Light Emitting Diode), and displays, a winning state or a win of a feature game or a bonus prize, which provide a high game value to the player, rendition of a game, and error occurrence. A speaker 19 generates audio assist, music, and sound effects, etc.
A plurality of lamps 20 provided on the front panel 3 carries out displays concerning the game, such as display of a win situation line validated in accordance with the inserted number of medals (or number of credits that are BET), and display of a win situation, by turning on, turning off, or blinking the lamps 20. An accumulated metal inserting button 21 is a button for using a predetermined number of medals accumulated (credited) in a not shown medal accumulation device, and an accumulated metal inserting button 22 is a button for using a maximum specified number of medals accumulated in a not shown metal accumulation device. A medal accumulated number display unit 23 displays the number of medals accumulated in the not shown metal accumulation device. A win situation number display unit 24 displays number of times of win situation and number of times left, during a bonus prize of a win situation. A medal pay-off number display unit 25 comprises for example, LED. A pay off button 26 pays off the accumulated medals, and a locking mechanism 27 locks the door, by a rotating direction. A format of the gaming machine 1 and a name of a maker is written on a label 28.
A clock generation circuit 33 which generates a standard clock pulse, and a random number generation circuit 34 which generates a certain number of random numbers, are connected to the CPU 30. The CPU 30, the ROM 31, the RAM 32, and the random number generation circuit 34 structure a drawing control unit. A control signal passed from the CPU 30 is output to a medal pay-off device 36 which carries out pay off of medals, and a display unit control circuit 37 which controls the symbol display unit 7 via an output port 35. The symbol display unit 7 and the display control circuit 37 structure the display unit.
A signal output from a medal determining device 38 which determines adequacy of a medal, a pay off medal counter 40 which counts the number of medals that are to be paid, and a start lever 41 which starts the rotation of the reels, is input to the CPU 30 via an input port 43. The signal output from the CPU 30 is output to the sub substrate B via a data sending circuit 46, receiving control from a sending timing control circuit 45 which controls signal sending timing to the sub substrate B.
In the sub substrate B, the signal output from the data sending circuit 46 is input to a data input circuit 47. The signal input to the data input circuit 47 is processed in a CPU 48. A clock generating circuit 49, a ROM 50 which has recorded various programs and image data, and a RAM 51 are connected to the CPU 48. Data concerning images is output to a liquid crystal displayer 53 via a display circuit 52 which carries out image processing, etc., from the CPU 48. In the liquid crystal displayer 53, characters, still images, and moving images, etc. are displayed. Data concerning sound is output to an amp circuit 56 via a sound LSI 54 which carries out sound processing, etc., from the CPU 48. The sound LSI 54 extracts necessary sound data from a sound ROM 55, and carries out processing of sound data.

On the other hand, as shown in
Reels A5, A7, and A9 that have displayed trigger symbols when a first feature game is started, are switched to re-drawing reels (Step S7). The reels A5, A7, and A9 that become re-drawing reels are called a “first re-drawing reel group” as one group. Symbol alignment is the same, and synchronously rotates and stops at the same position on the reel in each reel A5, A7, and A9 which structure the re-drawing reel group.
By this, an independent re-drawing result, which differs from the ordinary reel, can be displayed to the re-drawing reel group. Because a plurality of symbols are drawn for the ordinary reels where trigger symbols are not displayed, so that arbitrary symbols are independently displayed, the ordinary reels and the re-drawing reels are respectively independent, and mixed. Namely, re-drawing is not carried out using every region, but a re-drawing result is displayed in the re-drawing reels that are a part of the display regions, and in another one part of the region, the ordinary drawing result is displayed. By this, because two types of regions, the ordinary reels and the re-drawing reels coexist, and display drawing results, a new kind of game which arouses the player's interests, can be realized. Every display region may be a re-drawing reel (specific display region) in accordance with process of the game.
In the flowchart shown in
Then, it is determined whether there are any feature games (bonus games) left (Step S 11). In a case where there aren't any feature games left, the flow forwards to Step S17, and in a case where there are feature games left, it is determined whether a win situation is established in the ordinary reels (Step S12). In Step S12, in a case where a win situation is not established in the ordinary reels, the flow forwards to Step S14, and in a case where a win situation is established in the ordinary reels, the reels according to the win situation becomes a first+mth (m is a natural number) re-drawing reel group (Step S 13). In this case, it becomes a second re-drawing reel group.
In this way, during the period of a feature game, in a case where a win situation is established in whichever of the plurality of, ordinary reels, because the ordinary reels involved in the win situation are changed to new reels, independent from the existing reels, each time a win situation is established in the ordinary reels, the number of re-drawing reel groups increases. Because drawing is carried out from a plurality of types of symbols so that the same symbols are respectively stop displayed in each re-drawing reel group, diverse re-drawing can be carried out in each re-drawing reel group. As a result, a strong impression is provided to the players, and is possible to arouse the player's interests.
Then, it is determined whether there are any same symbols in whichever one of the re-drawing reel groups and an adjacent ordinary reel, or in another re-drawing reel group (Step S14). In a case where there isn't this kind of symbol, the flow forwards to Step S8, and in a case where there is this kind of symbol, the ordinary reel or the re-drawing reel group that has displayed the same symbols is combined to one re-drawing reel group (Step S 15). Namely, as shown in
In this way, in a case where a symbol displayed in whichever ordinary reel is the same symbol as the symbol displayed in the re-drawing reel group, because the ordinary reel is changed to a re-drawing reel and is combined to the existing re-drawing reel group, in a predetermined number of feature games after the next time, the number of reels that structure the re-drawing reel group increases. Then, because a drawing from a plurality of types of symbols is carried out so that a same symbol is stop displayed in every re-drawing reel group, the same symbol is stop displayed in the entire re-drawing reel group. By this, diverse re-drawing can be carried out in the specific display region, a strong impression is provided to the player, and it is possible to arouse the player's interest.
Next, the flow returns to Step S8, and a second feature game (bonus game) is carried out. Here, as shown in
Then, it is determined whether there are any same symbols in whichever one of the re-drawing reel groups and an adjacent ordinary reels, or in another re-drawing reel group (Step S 14). For example, in
In the next game, as shown in
In this way, in a case where the symbols displayed in each re-drawing reel group are the same, the re-drawing reel groups combine, and becomes one re-drawing reel group, and displays the same symbol. By this, diverse re-drawing can be carried out in the re-drawing reel. For example, by raising the odds, accompanying the increase in number of the re-drawing reels, the player's interests can be aroused.
As the above, a third to fifth feature game is carried out. Namely, in Step S9, in a case where a win situation is not established, it is determined whether a feature game (bonus game) is left (Step S 16), and in a case where there is a feature game (bonus game) left, the flow forwards to Step S8. On the other hand, in Step S16, in a case where there isn't a feature game (bonus game) left, the flow forwards to Step S17. In Step S11, in a case where there isn't a feature game (bonus game) left, the feature game (bonus game) ends (Step S 17), and moves to a game waiting state (Step S 18). At the BET time of the next game, the re-drawing reel is retuned to an ordinary reel (Step S 19). From the next game, an ordinary game is carried out once again.
In the second embodiment, a symbol display unit 7 displays a screen, such as shown in
Performance of the gaming machine according to the second embodiment, will be described with reference to
Then, it is determined whether a win situation is established or not (Step F3). In a case where a win situation is not established, the game ends (Step F20), and in a case where a win situation is established, every dividend corresponding to that win is paid (Step F4). The dividend at this time, is determined in accordance with the BET situation. For example, as shown in
Then, it is determined whether the win is a win situation established by the trigger symbol (Step F5). In a case where the win situation is not established by the trigger symbol, the game ends (Step F20). On the other hand, as shown in
Namely, the feature game is carried out in a case where a win situation is established by three ore more trigger symbols being adjacent. In the second embodiment, the number of times of the feature game is five times (Step F6). When the first free game is started, reels B1, B4, and B8 that have trigger symbols displayed, is switched to re-drawing reels (Step F7). The reels B1, B4, and B8 that become re-drawing reels are called a “first re-drawing reel group” as one group. In the same way as the first embodiment, symbol alignment is the same, and synchronously rotates and stops at the same position on the reel in each reel B1, B4, and B8 which structure the re-drawing reel group.
In the flowchart shown in
For example, in
Then, it is determined whether there are any feature games (bonus games) left (Step F11). In a case where there aren't any feature games left, the flow forwards to Step F17, and in a case where there are feature games left, it is determined whether a win situation is established in the ordinary reels by a trigger symbol (Step F12). In Step F12, in a case where a win situation is not established in the ordinary reels by the trigger symbol, the flow forwards to Step F14, and in a case where a win situation is established in the ordinary reels by the trigger symbol, the reels according to the win situation becomes a first+mth (m is a natural number) re-drawing reel group (Step F13).
Then, it is determined whether there are any same symbols in whichever one of the re-drawing reel groups and an adjacent ordinary reel, or in another re-drawing reel group (Step F14). In a case where there isn't these kinds of symbols, the flow forwards to Step F8, and in a case where there are theses kind of symbols, the ordinary reel or the re-drawing reel group that has displayed the same symbols is combined to one re-drawing reel group (Step F15).
For example, in
Next, the flow returns to Step F8, and a second feature game (bonus game) is carried out. Here, as shown in
In this way, during the period of a feature game, in a case where a win situation is established in whichever of the plurality of ordinary reels, by the trigger symbol being displayed, because the ordinary reels involved in the win situation are changed to independent reels other than the existing re-drawing reels, each time a win situation is established in the ordinary reels by the trigger symbol, the number of re-drawing reel groups increases. Because drawing is carried out from a plurality of types of symbols so that the same symbols are respectively stop displayed in each re-drawing reel group, the same symbol is respectively stop displayed in the re-drawing reel groups. By this, diverse re-drawing can be carried out in each-re-drawing reel group. As a result, a strong impression is provided to the players, and it is possible to arouse the player's interests.
Then, it is determined whether there are any same symbols in whichever one of the re-drawing reel groups and an adjacent ordinary reel, or in another re-drawing reel group (Step F14). In a case where there isn't this kind of symbol, the flow forwards to Step F8, and in a case where there is this kind of symbol, as above, the symbols are combined to the re-drawing reel group (Step F15). In the case shown in
When every ordinary reel and re-drawing reel stops, it is determined whether a win situation is established or not (Step F9). In a case where there is no win situation, the flow forwards to Step F16, and in a case where a win situation is established, every dividend is paid (Step F10). The dividend at this time is set in accordance with the BET state. Then, it is determined whether there are any feature games (bonus-games) left (Step F11). In a case where there aren't any feature games left, the flow forwards to Step F17, and in a case where there are feature games left, it is determined whether a win situation is established in the ordinary reels by the trigger symbol (Step F12). In Step F12, in a case where a win situation is not established in the ordinary reels by the trigger symbol, the flow forwards to Step F14, and in a case where a win situation is established in the ordinary reels by the trigger symbol, the reels according to the win situation becomes a first+mth (m is a natural number) re-drawing reel group (Step F13).
Then, it is determined whether there are any same symbols in whichever one of the re-drawing reel groups and an adjacent ordinary reel, or in another re-drawing reel group (Step F14). As shown in
In Step F9, in a case where a win situation is not established, it is determined whether a feature game (bonus game) is left, and in a case where there is a feature game (bonus game) left, the flow forwards to Step F8, and games are carried out until the number of feature games reaches a predetermined number (five times). In a case where there isn't a feature game (bonus game) left. In step S11, in a case where there isn't a feature game (bonus game) left, the feature game (bonus game) ends (Step F17), and moves to a game waiting state (Step F18). At the BET time of the next game, the re-drawing reel is retuned to an ordinary reel (Step F19). From the next game, an ordinary game is carried out once again.
In this way, in a case where the symbols displayed in each re-drawing reel group are the same, the re-drawing reel groups combine, and become one re-drawing reel group, and displays the same symbol. By this diverse re-drawing can be carried out in the re-drawing reel. For example, by raising the odds, accompanying the increase in number of the re-drawing reels, the player's interests can be aroused.
In the third embodiment, a win situation is established, in a case where three or more same symbols are adjacent in an ordinary game. In a case where a win situation is established by three trigger symbols being adjacent, feature games (bonus games) are carried out five games, after that game. In these feature games, reels where the trigger symbols appeared in the ordinary game, are switched to re-drawing reels. In a case where the same symbol is displayed in an ordinary reel that is adjacent to the re-drawing reels, the ordinary reel is combined to the re-drawing reels. Namely, the number of reels that structure the re-drawing reels increase. During the period of the feature game, a win situation by the trigger symbol, does not occur. The hardware structure of the gaming machine according to the third embodiment, can be structured in the same way as the first embodiment.
The performance of the gaming machine according to the third embodiment, will be described with reference to the flowcharts of
In the flowchart shown in
In the flowchart shown in
On the other hand, as shown in
In the flowchart shown in
In the fourth embodiment, in a case where a win situation is established by three trigger symbols being adjacent, feature games (bonus games) are carried out five games after that game. At the starting time of these feature games, reels where the trigger symbols appeared in the ordinary game, are switched to re-drawing reels. In a case where the same symbol is displayed in an ordinary reel that is adjacent to the re-drawing reels, the ordinary reel is combined to the re-drawing reels. Namely, the number of reels that structure the re-drawing reels increase. In a case where a plurality of re-drawing reels exist, when a same symbol is displayed in adjacent re-drawing groups, the re-drawing groups are combined, and become one re-drawing reel group. Further, in the fourth embodiment, differing from the third embodiment, a win situation is established by a trigger symbol, during the period of the feature game, and the number of feature games is added by that win. Namely, every time a win situation is established by the trigger symbol, during the period of the feature game, the number of feature games increase. In the feature game, in a case where a win situation is established in an ordinary reel by the trigger symbol, the ordinary reel according to that win, is switched to an independent re-drawing reel, which differs from the existing re-drawing reels. The hardware structure of the gaming machine according to the fourth embodiment, can be structured in the same way as the second embodiment.
Next, performance of the gaming machine according to the fourth embodiment will be described with reference to the flowcharts of
Then, it is determined whether there are any feature games (bonus games) left (Step T6). In a case where there aren't any feature games left, and a win situation by the trigger symbol is not established, the flow forwards to Step T14, and in a case where there are feature games left, or a win situation by the trigger symbol is established, it is determined whether there are any same symbols in whichever one of the re-drawing reel groups and an adjacent ordinary reels (Step T7). In a case where there isn't this kind of symbol, the flow forwards to Step T9, and in a case where there is this kind of symbol, the ordinary reel that has displayed the same symbols is combined to the re-drawing reels (Step T8).
For example, in
Then, it is determined whether the symbols in adjacent re-drawing reel groups are the same or not (Step T9). In a case where the symbols are not the same in the adjacent re-drawing reel groups, the flow forwards to Step T11, and in a case where the symbols are the same in the adjacent re-drawing reel groups, the re-drawing groups that have displayed the same symbol, are combined to one re-drawing reel group (Step T10).
Next, it is determined whether a win situation is established by the trigger symbol (Step T12). In a case where a win situation is not established by the trigger symbol, the flow forwards to step T3, and in a case where a win situation is established by the trigger symbol, a feature game (bonus game) of an addition of n times is added to the player. The number of additional games can be for example, five times.
The flow returns to Step T3 in
In Step T7, in a case where there isn't a same symbol in the ordinary reels adjacent to the re-drawing reel group, the flow forwards to Step T9, and in a case where there is a same symbol in an ordinary reel adjacent to the re-drawing reel group, the ordinary reel that has displayed the same symbol, is combined to the re-drawing reel group (Step T8). Then, it is determined whether re-drawing reel groups that have the same symbol are adjacent or not (Step T9). In a case where there are no adjacent re-drawing reel groups, the flow forwards to step T11. On the other hand, in a case where there are adjacent re-drawing reel groups, the re-drawing reel groups are combined to one re-drawing reel group (Step T10).
It is determined whether a win situation is established by the trigger symbol (Step T12). In a case where a win situation is not established by the trigger symbol, the flow forwards to Step T3, and in a case where a win situation is established by the trigger symbol, the player obtains feature games (bonus games) of an additional n times (Step T12). For example, in
In a third feature game, as shown in
When rotation of every reel stops, it is determined whether there-is a win situation or not (Step F9). In a case where a win situation is not established, the flow forwards to Step T13, and in a case where a win situation is established, every dividend corresponding to that win is paid (Step F5). The dividend at this time, is determined based on the BET situation. Then, it is determined whether there are any feature games (bonus games) left, or whether a win situation is established by the trigger symbol (Step T6). In a case where there aren't any feature games (bonus games) left and a win situation is not established by the trigger symbol, the flow forwards to Step T14. On the other hand, in a case where feature games (bonus games) are left, or a win situation is established by a trigger symbol, it is determined whether there is a same symbol in the ordinary reels adjacent to the re-drawing reel (Step T7). In a case where there isn't a same symbol in the ordinary reels adjacent to the re-drawing reel group, the flow forwards to Step T9, and in a case where there is a same symbol in an ordinary reel adjacent to the re-drawing reel group, the ordinary reel is combined to the re-drawing reel group (Step T8). Then, it is determined whether a same symbol is displayed in adjacent re-drawing reel groups (Step T10). As shown in
In the fourth feature game, as shown in
In Step T4, in a case where a win situation is not established, it is determined whether a feature game (bonus game) is left (Step T13), and in a case where there is a feature game (bonus game) left, the flow forwards to Step T3, and games are carried out until the number of feature games reaches a predetermined number. In a case where there isn't a feature game (bonus game) left, the flow forwards to Step T14. In Step T6, in a case where there isn't a feature game (bonus game) left, and there isn't a win situation by the trigger symbol, the feature game (bonus game) ends (Step T14), and moves to a game waiting state (Step T15). At the BET time of the next game, the re-drawing reel is retuned to-an ordinary reel (Step T16). From the next game, an ordinary game is carried out once again.
In the fifth embodiment, a win situation is established, in a case where three or more same symbols are adjacent in an ordinary game. In a case where a win situation is established by three trigger symbols being adjacent, feature games (bonus games) are carried out five games after that game. In these feature games, reels where the trigger symbols appeared in the ordinary game, are switched to re-drawing reels. In a case where the same symbol is displayed in an ordinary reel that is adjacent to the re-drawing reels, the ordinary reel is combined to the re-drawing reels. Namely, the number of reels that structure the re-drawing reels increases. In a case where a plurality of re-drawing reels exist, when a same symbol is displayed in adjacent re-drawing groups, the re-drawing groups are combined, and becomes one re-drawing reel group. During the period of the feature game, a win situation by the trigger symbol, does not occur. The hardware structure of the gaming machine according to the fifth embodiment, can be structured in the same way as the first embodiment.
The performance of the gaming machine according to the third embodiment, will be described with reference to the flowcharts of
In the flowchart shown in
When a first free game (bonus game) is started (Step R3), reels A5, A7, and A9 that have displayed trigger symbols, are switched to re-drawing reels (Step S7). The reels A5, A7, and A9 that become re-drawing reels are called a “first re-drawing reel group” as one group. Symbol alignment is the same, and synchronously rotates and stops at the same position on the reel in each reel A5, A7, and A9, which structure the re-drawing reel group.
For example, as shown in
Then, it is determined whether there are any feature games (bonus games) left (Step R6). In a case where there aren't any feature games left, the flow forwards to Step R14, and in a case where there are feature games left, it is determined whether a win situation is established in the ordinary reels that are adjacent to the re-drawing reel group (Step R7). In a case where there isn't this kind of symbol, the flow forwards to Step R9, and in a case where there is this kind of symbol, the ordinary reel that has displayed the same symbol is combined to one re-drawing reel group (Step R8). Namely, as shown in
Then, it is determined whether same symbols are displayed in adjacent re-drawing reel groups, in a case where a plurality of re-drawing reel groups exist (Step R9). In a case where same symbols are not displayed in adjacent re-drawing reel groups, the flow forwards to step R11, and in a case where same symbols are displayed in adjacent re-drawing reel groups, the re-drawing reel groups that have displayed the same symbol, are combined (Step R10). Next, it is determined whether a win situation is established in the ordinary reels (Step R11). In a case where a win situation is not established in the ordinary reels, the flow forwards to Step R3, and in a case where a win situation is established in the ordinary reels, the ordinary reels that have established a win, is switched to a re-drawing reel (Step R12). For example, in a case shown in
Next, the flow returns to Step R3, and a second feature game (bonus game) is carried out. Here, as shown in
In a case where a plurality of re-drawing reel groups exist, it is determined whether same symbols appear in adjacent re-drawing reel groups (Step R9). In a case where same symbols do not appear in adjacent re-drawing reel groups, the flow forwards to Step R10, and in a case where same symbols appear in adjacent re-drawing reel groups, the re-drawing reel group that has appeared the same symbol, is combined to one re-drawing reel group (Step R10). For example, as shown in
Next, it is determined whether a win situation is established in the ordinary reels (Step R11), and in a case where a win situation is not established, the flow forwards to Step R3, and in a case where a win situation is established, the reels according to that win are switched to re-drawing reels (Step R12). The case shown in
In the next game, as shown in
As the above, third to fifth feature games are further carried out. Namely, in Step R4, in a case where a win situation is not established, it is determined whether a feature game (bonus game) is left (Step R13), and in a case where there is a feature game (bonus game) left, the flow forwards to Step R3. On the other hand, in Step R13, in a case where there isn't a feature game (bonus game) left, the flow forwards to Step R14. In Step R6, in a case where there isn't a feature game (bonus game) left, the feature game (bonus game) ends (Step R14), and moves to a game waiting state (Step R15). At the BET time of the next game, the re-drawing reel is returned to an ordinary reel (Step R15). From the next game, an ordinary game is carried out once again.
As described in the first to fifth embodiment, by the condition of re-drawing reels appearing, the condition of reels that structure the re-drawing reels increasing, and the number of the re-drawing reels themselves increasing, the game variation increases. By applying a plurality of trigger symbols, a more diverse game can be carried out.
A gaming machine according to a sixth embodiment, differs from the above first to fifth embodiments, in that the gaming machine comprises a reel that displays three-position reels, i.e., a reel that can display symbols in three columns, up, medium, and bottom, in one reel. This gaming machine determines whether it is a win situation or not, by a win line. The reel that the gaming machine comprises may be a rotating drum type, or a video type.
In a waiting state of an ordinary game, a screen such as shown in
In the case shown in
Ways for the symbols to match, for a win situation to be established may be for example, “the symbols may be in any place, as long as it is on the win line”, “the symbols are adjacent on the win line”, “the symbols are adjacent in an order from left end to the right direction”, “the symbols are adjacent in an order from the right end to the left direction”, and “the symbols are adjacent in an order from left end to right direction and right end to left direction”, etc.
In the reels C1 to C5, a “scatter symbol” which is effective just by appearing in any reel, not concerning the win line. In the symbol display unit 7, a credit meter which displays number of credits, a BET meter which displays number of BETs, and a WON meter which shows the number of medals to be paid to the player when a win situation is established, are displayed.
In the sixth embodiment, in a case where three or more “trigger symbols”, which are scatter symbols, appear in any of three or more reels, feature games (bonus games) are carried out five games after that game. In these feature games, reels where the trigger symbols appeared in the ordinary game, are switched to re-drawing reels. The reel that has displayed a trigger symbol during a feature game, is switched to a re-drawing reel from the next game. Namely, the number of re-drawing reels that structure one re-drawing reel group increases. The hardware structure of the gaming machine according to the sixth embodiment, can be structured in the same way as the first embodiment.

Performance of the gaming machine according to a sixth embodiment structured as above, will be described with reference to flowcharts in
In the flowchart shown in
On the other hand, as shown in
Reels C2, C4, and C5 that have displayed trigger symbols when a first free game is started, are switched to re-drawing reels. The reels C2, C4, and C5 that become re-drawing reels are called a “re-drawing reel group” as one group. As shown in
When a feature game (bonus game) is started (Step P8), as shown in
Then, it is determined whether there are any feature games (bonus games) left (Step P11). In a case where there aren't any feature games left, the flow forwards to Step P15, and in a case where there are feature games left, it is determined whether a trigger symbol appeared in the ordinary reels or not (Step P12). In a case where a trigger symbol does not appear in the ordinary reels, the flow forwards to Step P8, and in a case where a trigger symbol appears in the ordinary reels, the ordinary reel that has appeared a trigger symbol is switched to a re-drawing reel, and combined (Step P13).
For example, in the case shown in
Next, the flow returns to Step P8, and as the above, the second to fifth feature games are carried out. As shown in
The seventh embodiment is also a gaming machine that comprises five reels, in the same way as the sixth embodiment. However, symbol alignment in the re-drawing reels and the ordinary reels are completely the same. Namely, the re-drawing reels in the seventh embodiment, do not have placed three same symbols sequentially, but have the same symbol alignment as the ordinary reels. In the seventh embodiment, when a trigger symbol appears in an ordinary reel during a feature game, the ordinary reel is switched to a re-drawing reel. Namely, the number of re-drawing reels that structure one re-drawing reel group increases. Other structure in the seventh embodiment, is the same as the sixth embodiment.
Performance of the gaming machine according to the seventh embodiment, will be described with reference to
On the other hand, in a case where a win situation is established by three or more trigger symbols appearing, a feature game as a bonus game is started. Namely, the feature game is carried out in a case where three ore more trigger symbols appear on whichever three or more reels. The number of times of the feature game is n (n is a natural number) times from the next game. In the seventh embodiment, the number of times of the feature game is five times (Step G6).
Reels that have displayed trigger symbols when a first free game (bonus game) is started (for example, reels D2, D4, and D5), are switched to re-drawing reels. The reels D2, D4, and D5 that become re-drawing reels are called a “re-drawing reel group” as one group. As shown in
When a feature game (bonus game) is started (Step G8), as shown in
Then, it is determined whether there are any feature games (bonus games) left (Step G11). In a case where there aren't any feature games (bonus games) left, the flow forwards to Step G15, and in a case where there are feature games (bonus games) left, it is determined whether triggers symbols have appeared in the ordinary reels (Step G 12). In a case where trigger symbols have not appeared in the ordinary reels, the flow forwards to Step G15, and in a case where trigger symbols have appeared in the ordinary reels, the ordinary reel that has appeared a trigger symbols is switched to a re-drawing reel, and combined (Step G13).
For example, in the case shown in
Next, the flow returns to Step G8, and as the above, the second to fifth feature games are carried out. As shown in
In the eighth embodiment, an embodiment where the number of re-drawing reel groups increase during a feature game, will be described. The structure of the gaming machine, is the same as the sixth embodiment.
The performance of the gaming machine according to the eighth embodiment, will be described with reference to the flowcharts of
When a first free game (bonus game) starts, the reel that has displayed a trigger symbol, is switched to a re-drawing reel. The reels that become re-drawing reels, are called a “redrawing reel group” as one group. Three same symbols may be placed sequentially in the redrawing reels, in the same way as the sixth embodiment, and may have the same symbol alignment as the ordinary reels, in the same way as the seventh embodiment. The re-drawing reels are set so that only the same symbols always stop on the reel. The re-drawing reels maintain a situation where the same symbols appear in every position, and carries out re-drawing of the symbols. Here, because a win situation is not necessarily established in a maintained state, it does not necessarily mean that a win situation is maintained.
When a feature game (bonus game) is started (Step Q3), the re-drawing reels (C2, synchronously rotate three sequential symbols, and the other reels independently rotate randomly. When the rotation of every ordinary reel and the re-drawing reel group stops, it is determined whether a win situation is established or not (Step Q4). In a case where a win situation is not established, the flow forwards to Step Q11. In a case where a win situation is established, every dividend is paid (Step Q5). The dividend at this time is set in accordance with the BET state.
Then, it is determined whether there are any feature games (bonus games) left, or whether there is a win situation by the trigger symbol (Step Q6). In a case where there aren't any feature games left and there isn't a win situation by the trigger symbol, the flow forwards to Step Q12, and in a case where there are feature games left, or there is a win situation by the trigger symbol, it is determined whether a win situation is established by the trigger in an ordinary reel (Step Q7). In a case where a win situation by a trigger symbol is not established in an ordinary reel, the flow forwards to step Q3, and in a case where a win situation by a trigger symbol is established in an ordinary reel, the player obtains a feature game (bonus game) of an addition of n times (Step Q8). Then, in the next game, the ordinary reel that has established a win situation by the trigger symbol, is switched to an independent re-drawing reel, which differs from the already existing re-drawing reels.
Then, it is determined whether same symbols are displayed in re-drawing reel groups, in a case where a plurality of re-drawing reel groups exist (Step Q9). In a case where there aren't 5 any re-drawing reel groups, wherein the same symbols appear, the flow forwards to Step Q3. On the other, in a case where there are re-drawing reel groups, wherein the same symbols appear, the re-drawing reel groups having the same symbols are combined to one re-drawing reel group (Step Q10). Because it is the first feature game, combining in Step Q10 is not carried out.
Next, the flow returns to Step Q3, and a second feature game is carried out. The re-drawing reel groups and the ordinary reels respectively rotate independently. When every ordinary reel and re-drawing reel stops, it is determined whether a win situation is established or not (Step Q4). In a case where win situation is established, every dividend is paid (Step Q5), and is determined whether any feature games (bonus games) are left, or whether there is a win by a trigger symbol (Step Q6). In a case where there aren't any feature games (bonus games) left, and there isn't a win by the trigger symbol, the flow forwards to Step Q12. On the other hand, in a case where a feature game (bonus game) is left, or there is a win by the trigger symbol, it is determined whether there is a win by the trigger symbol in and ordinary reel (Step Q7). In a case where there isn't a win by the trigger symbol in the ordinary reel, the flow forwards to Step Q3, and in a case where there is a win by the trigger symbol in the ordinary reel, the player obtains feature games (bonus games) of an additional n times, and the ordinary reel according to the win by the trigger symbol, is switched in the next game, to an independent re-drawing reel, different from the already existing re-drawing reels.
In a case where a plurality of re-drawing reel groups exist, it is determined whether same symbols appear in the re-drawing reel groups (Step Q9). In a case where there are re-drawing reel groups wherein a same symbol appears, the re-drawing reel group that has appeared the same symbol, is combined to one re-drawing reel group (Step Q10).
The flow forwards to step Q3, and feature games from the third feature game and later, are carried out. Namely, after the feature game is started (Step Q3), it is determined whether a win situation is established or not (Step Q4). In a case where a win situation is not established, it is determined whether any feature games (bonus games) are left (Step Q11), and in a case where there is a feature game (bonus game) left, the flow forwards to Step Q3. On the other hand, in Step Q11, in a case where there isn't a feature game (bonus game) left, the flow forwards to. Step Q12. In step Q6, in a case where there isn't a feature game (bonus game) left, the feature game (bonus game) ends (Step Q12), and moves to a game waiting state (Step Q13). At the BET time of the next game, the re-drawing reel is retuned to an ordinary reel (Step Q14). From the next game, an ordinary game is carried out once again.
Other than the above described sixth to ninth embodiments, reels that simply have a few same symbols sequentially placed can be used as re-drawing reels, and can carry out re-drawing so that a situation where same symbols appear in the positions of the up, middle and down column.
In the ninth embodiment, in a case where a symbol that establishes a specific win is top displayed in whichever of a plurality of ordinary reels, the ordinary reel that has displayed the symbols that establish a specific win are switched to re-drawing reels, in a predetermined number of games from the next game. Drawing from a plurality of types of symbols is carried out, so that at least one win from a same win group as the win group that the specific win belongs to, is established in the re-drawing reel.
For example, a poker game is carried out. As shown in
In the first feature game, symbols are drawn so that a win situation by two cards is established in the re-drawing reels (W1 and W2). In a poker game, it is “one pair”. During the feature game period, as shown in
In a gaming machine according to a ninth embodiment, in a case where there are for example, two re-drawing reels, symbols that have the possibility of being “one pair” is drawn. In a case where there are four re-drawing reels, symbols that have the possibility of being “two pair” or “four of a kind” is drawn. In a case where there are five re-drawing reels, symbols that have the possibility of being “straight”, “flush”, “full house” or “straight flush” is drawn.
The hardware structure of the gaming machine according to the ninth embodiment, is the same as the first embodiment.
Performance of the gaming machine according to the ninth embodiment will be described.
In the flowchart shown in
Then, it is determined whether a win situation is established or not (Step J3). In a case where a win situation is not established, the game ends (Step J17), and in a case where a win situation is established, every dividend corresponding to that win is paid (Step J4). The dividend at this time, is determined in accordance with the BET situation. Then, it is determined whether the win is a win situation established by the trigger symbol (Step J5). In a case where the win situation is not established by the trigger symbol, the game ends (Step J17).
On the other hand, as shown in
When a first feature game (bonus game) is started, reels W1 and W2 that have displayed trigger symbols, are switched to re-drawing reels (Step J7). The reels W1 and W2 that become re-drawing reels are called a “re-drawing reel group” as one group. Each reel W1 and W2 that structures the re-drawing reel group have the same symbol alignment, and synchronously rotates and stops at the same position on the reel, so as to stop display a symbol that establishes “one pair”.
A feature game (bonus game) is started, and the re-drawing reels (W 1 and W2) synchronize and change display symbols, and the other reels respectively change display symbols randomly. When change display of every ordinary reel and re-drawing reel group stops, it is determined whether a win situation is established (Step J8). In a case where a win situation is not established, the flow forwards to Step J13, and as shown in
Next, the flow returns to Step J7, and a second feature game (bonus game) is carried out. The re-drawing reel group (W1 and W2) and the other ordinary reels (W3 to W5) respectively change display symbols independently. When every ordinary reel and re-drawing reel stops, it is determined whether a win situation is established or not (Step J8). For example, as shown in
In the next game, the reel group (W1, W2, and W3) and the ordinary reels (W4 and W5) independently change displays and stop displays symbols. Then, in the re-drawing reel group (W1, W2, and W3), drawing is carried out from a combination of symbols that can establish for example, “three card”, as shown in
As the above, third to fifth feature games are carried out. Namely, in Step J8, in a case where a win situation is not established, it is determined whether there are any feature games (bonus games) left (Step J13), and in a case where feature games (bonus games) are left, the flow forwards to Step J7. On the other hand, in a case where there aren't any feature games (bonus games) left, the flow forwards to Step J14. In Step J10, in a case where there aren't any feature games (bonus games) left, the feature game (bonus game) ends (Step J14), and moves to a game waiting state (Step J15). At the BET time of the next game, the re-drawing reel is retuned to an ordinary reel (Step J16). From the next game, an ordinary game is carried out once again.
In this way, according to the ninth embodiment, in a case where symbols that establish a specific win are stop displayed in whichever of a plurality of ordinary reels, because drawing is carried out from a plurality of types of symbols so that any one win of a same win group as the win group that the specific win belongs to (group to which the win belongs to) is established, the win can be changed, maintaining the win situation. By this, players feel intrigued, and the player's interest towards the game can be raised. In the ordinary reels that have displayed symbols other than symbols that establish a specific win, because drawing is carried out from a plurality of types of symbols, so that arbitrary symbols are respectively displayed independently, ordinary reels and re-drawing reels independently exist and co-exist. Namely, re-drawing is not carried out using every reel, but re-drawing results are displayed in re-drawing reels, which are part of the display region, and ordinary drawing results are displayed in one part of the remaining display region. By this, because drawing results are displayed by two types of regions: the re-drawing reels and the ordinary reels, existing, a new kind of game that arouses the player's interests can be realized. Every display region can become a re-drawing reel, in accordance with the course of the game.
Besides the embodiments described above, as a result of drawing, in a case where a symbol that is to be displayed in whichever ordinary reel is the same as the symbol to be displayed in the re-drawing reel, in special games of a predetermined number of times after the next game, the ordinary reel and the re-drawing reel may be combined. Namely, in a case where a symbol that is the same as the re-drawing reel is displayed in an ordinary reel that is not necessarily adjacent, the ordinary reel and the re-drawing reel are combined.
By this, during the period of the feature game, every time a same symbol as the re-drawing reel is displayed-in an ordinary reel, the number of reels that structure the re-drawing reel group increases. Because drawing is carried out from a plurality of types of symbols so that the same symbol is stop displayed in every re-drawing reel, the same symbols are stop displayed in the re-drawing reel group. By this, diverse re-drawing can be carried out in the re-drawing reels. As a result, a strong impression can be provided to the players, and it is possible to arouse the player's interests.
Characteristic performance of the present invention such as above, can be carried out by controlling a computer to execute a control program. Namely, this control program is structured so that a series of processing including: a processing of displaying a plurality of types of symbols in a plurality of display regions (for example, A1 to A9 shown in
In this way, in a case where a predetermined symbol is stop displayed in a plurality of display regions, the display regions that stop display the predetermined symbols are set as specific display regions, and because drawing in a predetermined times of games after the first game is carried out from a plurality of types of symbols that are to be displayed, so that there is a specific relationship among the symbols in each game, symbols having a predetermined relationship are displayed in the specific display region. By this, an independent drawing result (re-drawing result) which differs from the general display region can be displayed in the specific display region. The display regions other than the specific display regions are set as general display regions. In the general display regions, because drawing is carried out from a plurality of types of symbols that are to be displayed without the symbols having a predetermined relationship, the general display regions and specific display regions are respectively independent and coexist. Namely, re-drawing is not carried out using every region, but re-drawing result is displayed in the specific display regions, which are a part of the display regions, and in the region of a remaining part, ordinary drawing result is displayed. By this, because drawing results are displayed by two types of regions: the specific display regions and the ordinary display regions, existing, a new kind of game that arouses the player's interests can be realized. Every display region can become a specific display region, in accordance with the course of the game.
Another control program is structured so that a series of processing including: processing of displaying changing display which displays, constantly changing a plurality of symbols in a stopped state to a plurality of types of symbols on a plurality of display regions (for example, A1 to A9 shown in
In this way, in a case where a predetermined symbol is stop displayed in a plurality of display regions, the display regions that stop display the predetermined symbols are set as specific display regions, and because drawing in a predetermined times of games after the first game is carried out from a plurality of types of symbols that are to be displayed, so that the symbols are displayed the same in each game, same symbols are displayed in the specific display region. By this, an independent re-drawing result which differs from the general display region can be displayed in the specific display region. The display regions other than the specific display regions are set as general display regions. In the general display regions, because drawing is carried out from a plurality of types of symbols that are to be displayed, so that symbols are independently displayed, the general display regions and specific display regions are respectively independent and co-exist. Namely, re-drawing is not carried out using every region, but re-drawing result is displayed in the specific display regions, which are a part of the display regions, and in the region of a remaining part, ordinary drawing result is displayed. By this, because drawing results are displayed by two types of regions: the specific display regions and the ordinary display regions, existing, a new kind of game that arouses the player's interests can be realized. Every display region can become a specific display region, in accordance with the course of the game.
Another control program is structured so that a series of processing including: processing of displaying a plurality of types of symbols in a plurality of display regions (for example W1 to W5 in
In this way, in a case where a predetermined symbol that establishes a specific win is stop displayed in a plurality of display regions, the display regions that stop display the predetermined symbols that establish a specific win are set as specific display regions in a predetermined times of games from the next game, and because drawing is carried out from a plurality of types of symbols that are to be displayed, so that which ever one win that is the same as a win group that the specific win group belongs to (the group to which the win belongs to) is established in each game, wins can be changed in each game, maintaining a win situation. By this, players feel intrigued, and can raise the player's interest towards the game. The display regions other than the specific display regions are set as general display regions. In the general display regions, because drawing is carried out from a plurality of types of symbols that are to be displayed, so that symbols are independently displayed, the general display regions and specific display regions are respectively independent and co-exist. Namely, re-drawing is not carried out using every region, but re-drawing result is displayed in the specific display regions, which are a part of the display regions, and in the region of a remaining part, ordinary drawing result is displayed. By this, because drawing results are displayed by two types of regions: the specific display regions and the ordinary display regions, existing, a new kind of game that arouses the player's interests can be realized. Every display region can become a specific display region, in accordance with the course of the game.
The above program can be obtained by being recorded in a recording medium such as a CD-ROM and DVD, etc. This kind of program can also be obtained by receiving a signal sent by a computer that is a sending device, via communication networks, etc., constituted of a public telephone line, a dedicated phone line, a cable television circuit, or a radio communication line, etc., that structures a network. This signal is a computer data signal converted by a predetermined carrier wave that includes the program. At the time of sending, at the least, one part of the above program needs to be transmitted. Namely, every data that structures the above program, does not need to exist in the transmission media at one time. In a sending method for sending the program from the above computer, a case of sequentially sending data that structures the program, and a case of intermittently sending is included.
As described above, the gaming machine of the present invention comprises a display unit which can display a plurality of types of symbols on a plurality of display regions, upon starting a game, and a draw control unit which in a case where predetermined symbols are to be displayed stopped on a plurality of the display regions, sets the display regions where the predetermined symbols are to be displayed stopped, as a specific display region, and in a predetermined times of games after the first game, draws for the specific display region, symbols from the plurality of types of symbols that are to be displayed, so that there is a specific relationship among the symbols in each game, and at the same time which sets the display regions other than the specific display region as a general display region, and draws for the general display region, a symbol from the plurality of types of symbols that are to be displayed, so that there isn't a predetermined relationship among the symbols.
In this way, in a case where a predetermined symbol is stop displayed in a plurality of display regions, the display regions that stop display the predetermined symbols are set as specific display regions, and because drawing in a predetermined times of games after the first game is carried out from a plurality of types of symbols that are to be displayed, so that there is a specific relationship among the symbols in each game, symbols having a predetermined relationship are displayed in the specific display region. By this, an independent drawing result (re-drawing result) which differs from the general display region can be displayed in the specific display region. The display regions other than the specific display regions are set as general display regions. In the general display regions, because drawing is carried out from a plurality of types of symbols that are to be displayed without the symbols having a predetermined relationship, the general display regions and specific display regions are respectively independent and co-exist. Namely, re-drawing is not carried out using every region, but re-drawing result is displayed in the specific display regions, which are a part of the display regions, and in the region of a remaining part, ordinary drawing result is displayed. By this, because drawing results are displayed by two types of regions: the specific display regions and the ordinary display regions, existing, a new kind of game that arouses the player's interests can be realized. Every display region can become a specific display region, in accordance with the course of the game.
In another embodiment of the present invention described herein includes a video gaming machine 100 preferably installed in a casino. Referring to
The three display units 103A, 103B, and 103C each include a flat display device preferably, or a liquid crystal display device more preferably. The display units 103A, 103B, and 103C produce various images, for example, images for use in decoration and advertisements, e.g., the logo of a game developer, images for use in visual effects in games, and visualized information on games, e.g., pay tables, illustrations of game content, and jackpot meters.
In particular, the middle display unit 103B displays a game screen.
On each video reels 141A-141E, symbols 142 can be repeatedly moved and stopped in a vertical direction at each round of game. In other words, the video reels 141A-141E can separately spin and stop at each round. In a spin of each video reel, different types of symbols 142 appear in a predetermined order. The order preferably varies with video reels. After a predetermined time has elapsed from the start of the spin of the video reels 141A-141E, symbols 142 will be stopped column by column in an arrangement. The arrangement is randomly changed at every round of game. On each video reel 141A-141E in a stop position, preferably three or more symbols 142 are aligned in a column. The video reels 141A-141E are preferably divided into two types, i.e., a long type and a short type. A long-type video reel 141B and 141D preferably includes one more symbols than a short type video reel 141A, 141C, and 141E. Long- and short-type video reels are alternately arranged on the game screen 140A. As a result, all symbols 142 are preferably arranged on a honeycomb or hexagonal lattice when all the video reels 141A-141E are stopped. Note that symbols 142 may be arranged on another type of lattice, e.g., a square lattice.
The gaming machine 100 preferably conducts a game having two modes, i.e., a normal mode and a bonus mode. Details of rounds in the two modes will be described below. The appearances of the video reels 141A-141E are preferably changed depending on whether a round of game is in a normal or bonus mode.
The gaming machine 100 provides a player with an award depending on a winning combination of symbols appearing on stopped video reels. Types of winning combinations can be determined by various rules. Each winning combination preferably pay from left to right in both of normal and bonus rounds. In the case of the video reels 141A-141E shown in
As easily understood through a comparison between
The coin slot 105 and the bill slot 106 allow a player to enter coins and bills thereinto, respectively. The entered coins and bills are counted by a counter and validated by an acceptor. The counter and the acceptor are preferably installed inside the cabinet 101. The total amount of the validated coins and bills are displayed on the middle display unit 103B as credits available to the player. A coin hopper installed inside the cabinet 101 stores a large number of coins and bills together with the coins and bills entered by the player. The coin hopper discharges coins or bills equivalent to credits that a player has won on a game through the coin chute 109 into the coin tray 110 or through the bill slot 106, respectively. Note that the gaming machine 100 may support a ticket-in/ticket-out system, i.e., accept and print a bar-coded paper ticket. A bar code printed on the ticket represents monetary data available to a player.
The push buttons 108 allow a player to operate the gaming machine 100. For example, by using the push buttons 108, a player can place a desired amount of a bet on each round of game. The player then pushes a spin button included in the push buttons 108 to cause the video reels 141A-141E to start spinning. After a predetermined time has elapsed, if the arrangement of stopped symbols 142 includes a winning, combination, the player will win an award depending on the amount of the bet and the type of the winning combination. The player will be allowed to push a cash-out button included in the push buttons 108, and then receive coins or bills equivalent to his/her credits from the coin chute 109 or the bill slot 106, respectively. The player may also use a push button 108 to select coins or bills into which his/her credits are to be converted. The push buttons 108 are preferably lamp buttons, which each include a light-emitting device and lights up when pushed by a player or used in lighting effects during game play.
The speaker 111 is installed inside the cabinet 101, and generates voice announcements and sound effects during game play.
The above-described components of the gaming machine 100 are preferably controlled by a game controller unit that is preferably installed inside the cabinet 101. Alternatively, the game controller unit may be separated from the cabinet 101, and connected through a network to the components of the cabinet 101.
Referring to
The CPU 121 executes various programs, and thereby controls other components of the game controller unit according to instructions and data accepted by the console unit 125. The CPU 121 in particular executes a game program, and thereby conducts a game having normal and bonus modes. The ROM 122 stores programs and databases used by the CPU 121. The ROM 122 in particular stores image data for producing two types of game screens 140A and 140B and various symbols 142 on the middle display unit 103B. The RAM 123 temporarily stores variables, parameters, and the like that are used by the CPU 121.
The credit controller unit 124 manages the amount of player's credits, which is equivalent to the amount of coins and bills counted and validated by the counter/acceptor 124A. The console unit 125 monitors the push buttons 108 and accepts various instructions and data that a player enters through the push buttons 108. The payout controller unit 126 changes player's credits to coins, bills, or other monetary data by using the coin hopper 126A or the like.
The random-number generator unit 128 generates and outputs random numbers to the CPU 121 preferably at the start of each round of game. The CPU 121 uses the random numbers to randomly select an arrangement of symbols 142 to be displayed on the video reels 141A-141E when they will stop. Each of the random numbers is uniquely assigned to one of the video reels 141A-141E. The CPU 121 retrieves stop positions of the video reels 141A-141E linked to the random numbers from respective stop position tables. Here, the stop position of a video reel corresponds to types of symbols 142 to be displayed on the video reel when it stopped. The stop position tables are preferably stored in the ROM 122. Each of the stop position tables is assigned to one of the video reels 141A-141E, and represents relationship between random numbers and stop positions of the video reel. Thus, the CPU 121 selects stop positions of the video reels 141A-141E at random.
The random-number generator unit 128 preferably generates the same number of random numbers as the video reels 141A-141E at each normal round, and the same number of random numbers as groups of the video reels 141A-141E at each bonus round. In the case where five video reels 141A-141E are prepared as shown in
The CPU 121 preferably uses the random numbers to determine whether or not to provide an award to a player at random in the following manner. The CPU 121 retrieves the random numbers from a winning combination table stored in the ROM 122. The winning combination table represents relationship between combinations of random numbers and types of awards. Here, in the stop position tables, the same combination of random numbers as that included in the winning combination table is linked to a stop position of the video reels 141A-141E in which a winning combination appears. Accordingly, a type of an award is assigned to each winning combination appearing on the stopped video reels 141A-141E. Note that the ROM 122 preferably stores two different types of winning combination tables, one used in the normal mode and the other used in the bonus mode. The CPU 121 preferably selects a type of a winning combination table depending on whether a round is in the normal or bonus mode. If the CPU 121 retrieves an award linked to the combination of the random numbers from the selected winning combination table, the CPU 121 then decides to provide the award to a player. More specifically, the CPU 121 will increase the player's credits by a payout, or change the normal mode to the bonus mode.

Wildcard symbols can preferably appear on the video reels 141A-141E. Referring to
Trigger symbols can preferably appear on the video reels 141A-141E. Referring to
At a bonus round, the CPU 121 uses only three random numbers to determine stop positions of the video reels 141A-141E and decide whether or not to provide an award. The types of random numbers are reduced on a condition that symbols 142 are arranged in the same order and at the same positions in each pair or group of the video reels 141A-141E as shown in

Preferably, trigger symbols, e.g., “star” symbols 142B in
The lighting controller unit 129 controls lighting devices 129A installed in the three display units 103A, 103B, and 103C, the push buttons 108, and other lumps mounted on the cabinet 101 during game play. The lighting controller unit 129 thereby causes the lighting devices 129A to blink and/or change brightness and color in specific patterns in order to produces lighting effects. The sound controller 130 controls the speaker 111 to output voice announcements and sound effects during game play.
The display controller unit 131 controls the three display units 103A, 103B, and 103C to display various images on screens preferably by using computer graphics and image data stored in the ROM 122. The display controller unit 131 in particular controls video reels in a game screen displayed on the middle display unit 103B by using computer graphics and the image data.
The display controller unit 131 further controls video reels in different manners depending on whether a round of game is in a normal or bonus mode.

A player inserts coins or bills into the coin slot 105 or the bill slot 106, respectively. Then, the counter/acceptor 124A validates the coins and bills, and counts the valid coins and bills. The game controller unit reads the count and updates credit data stored in the RAM 123 to increase player's credits by the number corresponding to the count. Then, the game controller unit starts a normal round of game. When the console unit 125 accepts a bet placed by the player through the buttons 108, the game controller unit enables the console unit 125 to accept a cue to start spinning of video reels 141A-141E from a spin button, one of the buttons 108. When the console unit 125 detects a push of the spin button 108, the game controller unit updates the credit data stored in the RAM 123 to decrease the amount of the credits by the amount of the bet.
The game controller unit causes the random number generator unit 128 to generate five random numbers. The game controller unit then retrieves stop positions of the video reels 141A-141E linked to the five random numbers from respective stop position tables. Thus, the game controller unit selects stop positions of the video reels 141A-141E at random, and stores data representing the stop positions into the RAM 123, preferably.
The game controller unit also retrieves the five random numbers from a winning combination table for use in the normal mode. If the game controller unit retrieves an award linked to the combination of the five random numbers from the winning combination table, the game controller unit then decides to provide the award to the player.
The game controller unit instructs the display controller unit 131 to cause the middle display unit 103B to start spinning the video reels 141A-141E. Then, the video reels 141A-141E start spinning as shown in
At predetermined time intervals, the display controller unit 131 causes the middle display unit 103B to stop the video reels 141A-141E one by one into their respective stop positions selected by the game controller unit. Then, the video reels 141A-141E stop in positions as shown in
If the game controller unit has decided to provide the player with a payout, a corresponding winning combination appears on the stopped video reels 141A-141E. Referring to
If the game controller unit has decided to provide the player with a right to play a bonus round, three or more trigger symbols are scattered on the stopped video reels 141A-141E. Referring to
The game controller unit preferably conducts a bonus round for free, i.e., allows a fixed bet to be placed without reducing the player's credits. Note that the game controller unit may use a portion of the player's credits as a bet.
At the start of a bonus round, the game controller unit enables the console unit 125 to accept a cue to start spinning of video reels 141A-141E from a spin button. When the console unit 125 detects a push of the spin button 108, the game controller unit causes the random number generator unit 128 to generate three random numbers. The game controller unit then retrieves stop positions of the left three video reels 141A-141 C linked to the three random numbers from respective stop position tables. Thus, the game controller unit stores data representing the stop positions into the RAM 123, preferably.
The game controller unit also retrieves the three random numbers from a winning combination table for use in the bonus mode. If the game controller unit retrieves an award linked to the combination of the three random numbers from the winning combination table, the game controller unit then decides to provide the award to the player.
The game controller unit instructs the display controller unit 131 to cause the middle display unit 103B to start spinning the video reels 141A-141E. Then, the video reels 141A-141E start spinning as shown in
At predetermined time intervals, the display controller unit 131 causes the middle display unit 103B to stop the video reels 141A-141E pair by pair into their respective stop positions selected by the game controller unit. Preferably, the display controller unit 131 stops the pairs in the order from outermost to innermost as follows.
First, the display controller unit 131 stops the outermost pairs, i.e., the pair of the first video reel 141A and the fifth video reel 141E in the same stop position as shown in
Second, the display controller unit 131 stops the next inner pairs, i.e., the pair of the second video reel 141B and the fourth video reel 141D in the same stop position as shown in
Referring to
Finally, the display controller unit 131 stops the third video reel 141C in a stop position determined by the game controller unit in advance.
If the game controller unit has decided to provide no award to the player in advance, at most two symbols of the same type appear on the stopped video reels 141A-141E. The game controller unit finishes the bonus round, and then starts the next bonus round.
If the game controller unit has decided to provide the player with a payout, a corresponding winning combination appears on the stopped video reels 141A-141E. Referring to
If a predetermined times of bonus rounds has been finished, the game controller unit changes the bonus mode to the normal mode, and waits until the console unit 125 accepts a new bet or an instruction from the player. If instructed by the player, the game controller unit may convert his/her credits into cash or the like by using the payout controller unit 126.
In the above-described manner, the game controller unit determines an arrangement of symbols on the condition that symbols are arranged in the same order and at the same positions in two or more columns at a bonus round. Accordingly, chances are fairly better that a winning combination will appear in the arrangement in a bonus round than in a normal round. Furthermore, the display controller unit 131 causes the middle display unit 103B to spin the two or more columns of symbols from the same position in synchronization with each other as shown in
Note that symbols may be arranged in a square lattice on a game screen. In this case, each vertical line of the square lattice forms a video reel. All horizontal lines and/or slanted lines of the square lattice are preferably selectable as paylines. A player guesses on which payline a winning combination, e.g., three or more aligned symbols of the same type will appear, and then places a bet on a desired payline before symbols are changed in their arrangement. If a winning combination appears on the payline where the player has placed a bet, the player will win an amount of a payout that depends on the amount of the bet and the type of the winning combination. When a game is conducted by this rule, the gaming machine arranges symbols on left-right symmetric video reels in a bonus round. This also enables the gaming machine to provide a player with a better chance of winning an award in a simple manner, and cause the player to recognize the chance through simple and clear visual effects, without any heavy burden on game designers and developers.
The video reels 141A-141E may be replaced with mechanical reels. In this case, the same symbol sequences are displayed or printed on the circumferential surfaces of the first and fifth reels. Similar is true for the second and fourth reels.
With reference to
A game controller (not shown) pre-selects at random, at the initiation of a game sequence, a potential win element for each reel from the set of elements. That is, the game controller predetermines which element, and therefore which symbol, will be displayed in a pay line position at the end of a game sequence, and may therefore contribute to a winning outcome.
In this first preferred embodiment of the invention, at least one reel, the first left-most reel, is arranged to have at least one run of an identical symbol in each of a number of consecutive elements. The arrangement is shown schematically in
The game controller (not shown) determines the identical symbol to be displayed in each consecutive element of the run or runs of consecutive elements in which the symbol is to be shown. The selection of the identical symbol is through a notional rotation of an “inner reel” 234 shown as a strip of elements and symbols in
The symbols of the “inner reel” or look-up table from which the selection is made, are a sub-set of the set of symbols displayed in the remaining non-“inner reel” elements of the left-most reel. Thus, where the symbols are those of a suit of cards, the “inner reel” symbols may be those of the Ace, King, Queen and Jack, sometimes called the trump or court cards. The look-up table could also include a “wild” or “scatter” symbol. As previously noted, the arrangement or ordering of the symbols in the elements of the reel, other than the consecutive run or runs of elements, remain constant for every game, only the selection of the identical symbol from the look-up table is performed anew for each new play of a game.
The symbols 236 of the look-up table 234 need not all have the same probability of selection but may be assigned a hierarchy of probability. Thus for example, those symbols for which a winning combination confers on the player of a game a relatively higher value prize, such as the ace and the king, may have an inversely proportional probability of being selected as an “inner reel” symbol.
The reels are now spun as normal. The player will notice the run or runs of identical symbols passing through the display 212 for each revolution of the left-most reel 226, thereby providing a heightening of interest, since the odds of a winning arrangement of symbols appearing on a pre-defined pay line in the matrix at the conclusion of the game sequence will be increased.
In another embodiment of the invention, the second reel, that is the second reel from the left in this example, may also be modified to include at least one run of consecutive elements displaying the same “inner reel” symbol as that used to populate the elements of the consecutive run or runs of the left-most reel. As for the first, left-most reel, the number and location of the consecutive elements of the potential run or runs within the strip of elements forming the simulated reel, is predetermined and remains constant.
Prior to modification, all the elements of the second reel (and likewise those of the third fourth and fifth reel) are randomly populated with symbols from the set of available symbols. Unless modification is triggered in the manner explained below, the ordering of these symbols within the elements of the reels remains constant for every game; only those symbols of the potential run or runs being displaced should a modifying event occur.
The populating of the potential “inner reel” elements of the second reel, and of any subsequent reels, is dependent on the potential win element for the first, or preceding reel, which was randomly selected by the game controller, lying within a run of consecutive elements of that reel. For example if, as shown in
A player will now discern a bias of symbols, (in our example crown symbols), in both the first, left-most, and second reels as these are spun during the play of a game. The effect is clearly an increase in the probability of a winning combination of symbols appearing along a pre-defined pay line within the matrix and consequently a raised level of interest in the outcome of the game for the player.
The same process of populating potential “inner reel” elements with the “inner reel” symbol of the preceding reel, may be sequentially applied to the third, fourth and fifth reels. As described for the second reel, the modification of a succeeding reel depends on the selected potential win element of the preceding reel falling within a run of “inner reel” elements of that reel.
In another embodiment of the present invention, a player is made aware of the populating of one or more consecutive runs of the left-most reel with the identical symbol. This may be done prior to the main game sequence, for example, by a slower pre-spin of only the left-most reel. If any further reels are so populated, each may be pre-spun sequentially.
The displayed game rules and experience will alert a player to the fact that the potential winning element for a given reel is positioned somewhere within the run, or one of the runs of consecutive elements populated with the identical symbol if the second and any subsequent reels are also pre-spun to display a run or runs of that symbol. The player will appreciate that the probability of a winning combination occurring increases with each additional reel which is pre-spun to display its run or runs of elements with the same symbol.
The above described embodiments may be applied to a main game of a gaming machine or to a feature game offered as a result of some triggering event in a main game.
In a preferred embodiment of the invention as adapted for a feature game, the number of elements comprising a run of identical “inner reel” symbols and the number of such runs in any given reel is not constant but may be determined in a number of ways. Thus, in at least one preferred embodiment, the number of elements comprising a run may be a function of the amount of a bet placed by the player on the main game which triggered the feature game, or as a function of accumulated throughput of bets over a given time period. In one special case, all the elements of the first left-most reel may be populated by the same “inner reel” symbol.
Likewise, the number of runs in a given reel may be a function also of the betting pattern preceding the conferring of the feature game or alternatively, may be a function of the particular triggering event of the main game which led to the feature game.
In another embodiment, the elements comprising the matrix of elements of any of the above described embodiments may also be of conventional rectangular configuration, but in at least one preferred embodiment the delineation of an element, that is, the boundary defining the field containing a symbol, may be any N-sided figure, where N may take the value 1 (thus a circular field) or any value from 3 to 20. In at least one preferred form of N-sided element, as shown in
Any of the above described embodiments may be implemented on any gaming machine or group of gaming machine provided with a control module. As shown in
Control module 260 acts to implement appropriate elements of the program code according to inputs from a user keyboard 268 and outputs video imagery to at least a main display module 270.

In a further preferred embodiment of the invention as shown in
In yet a further preferred embodiment of the invention as shown in
Each of machines 410 of the embodiment illustrated in
A win of the jackpot prize may be triggered by specific outcomes of either a main game or of a feature game. If the jackpot trigger is dependent on an outcome of the feature game, players on adjoining machines may be made aware by means of the common display that a potential triggering of the jackpot is to commence on the machine offered the feature game, thus adding interest for all the players.
It will be appreciated that the linked machines may form part of Local Area Networks (LAN) or Wide Area Networks (WAN).
In one embodiment, before spinning the reels 141A-141E to display the second instance outcome 426, the game controller 121 may rotate the selected reels 141B and 141D to synchronize the display of the symbols 142. In another embodiment, the game controller 121 may spin the reels 141B and 141D and adjust a rotation of the selected reels 141B and 141D to synchronize the display of the symbols 142 while the reels 141B and 141D are spinning (shown in
In the illustrated embodiment, the game controller 121 selects a first group 428 of reels such as, for example, reels 141B and 141D, and selects a second group 430 of reels such as, for example, reels 141A and 141E. During the second instance 422 of the game, the game controller 121 synchronizes reels 141B and 141D of the first group 428 to display the same symbol 142 in the same symbol positions 214, and synchronizes reels 141A and 141E of the second group 430 to display the same symbols 142 in the same symbol position 214 (shown in
The game controller 121 may also display the selected reels 141B and 141D having a run of consecutive elements 230, for example, a run of consecutive symbol positions 232, and display the same symbol 142 in each consecutive symbol position 232. During the second initiation 420, the game controller 121 may randomly select the same symbol 142 and/or similar symbols 142 to be displayed in each of the consecutive symbol positions 232. In addition, the game controller 121 synchronizes the selected reels 141B and 141D to synchronize the display of the consecutive symbol positions 232. In one embodiment, the game controller 121 may populate the run of consecutive elements 232 in each of the selected reels 141B and 141D while the reels 141B and 141D are spinning such that the player is made aware of the population of the run of consecutive elements with the same symbols 142.
In one embodiment, illustrated in
In the illustrated embodiment, in the first instance 420 of the game, the game controller 121 displays at least one reel such as, for example, reel 141C with a run of consecutive elements 232. For example, as shown in
In one embodiment, the game controller 121 may populate the run of consecutive elements 232 in the reel 141C with an identical symbol 142 in the first instance 420 and display the run of consecutive elements 232 with the identical symbol 142 in the second instance 422. Alternatively, the game controller 121 may replace the symbols 142 displayed in the run of consecutive elements 232 with another symbol 142 during the second instance 422. In addition, the game controller 121 may select the synchronized reels 141B and 141D such that the held reel 141C is between the synchronized reels 141B and 141D.
