The present application claims priority from Japanese Patent Applications No. 2015-064616 filed on Mar. 26, 2015, No. 2015-064626 filed on Mar. 26, 2015, No. 2015-064556 filed on Mar. 26, 2015, and No. 2015-064571 filed on Mar. 26, 2015, the disclosures of which are herein incorporated by reference in its entirety.
The present invention relates to a gaming machine that yields a rescue award, when a game continues without awarding of any benefit.
Traditionally, in a facility where gaming machines such as slot machines and the like are set up, games are played by betting various types of gaming medium such as a credit and the like in the slot machines. In each slot machine are set a plurality of result determination areas (areas for which determination of win or loss is carried out) on which a bet is placeable, and a benefit (payout) is awarded based on the number of result determination areas on which a bet is placed, the number of bet credits, and the game result (see for example, Japanese Unexamined Patent Publication No. 2008-229017; hereinafter PTL 1).
Further, amongst the slot machines are those configured to perform an awarding (rescue) to the player, when the number of plays resulting no benefit reaches a predetermined number (see for example Specification of Publication of U.S. Pat. No. 5,910,048; hereinafter, PTL 2). For example, a constant amount of payout is awarded when the number of plays of the game resulting in no benefit reaches a predetermined value (so-called ceiling number).
It however may lead to unfairness if the rescue is conducted in the same manner, no matter the bets are placed only on a few result determination areas or on many result determination areas.
In view of the above, it is an object of the present invention to provide a gaming machine configured to yield a rescue award according to the number of result determination areas on which the player has placed a bet, when games without any benefit are continued.

Another aspect of the present invention is a gaming machine, comprising: a display device configured to display a game result by rearranging a plurality of types of symbols aligned on a plurality of video reels;
a storage unit configured to store a payout table in which a plurality of symbol combinations and a plurality of payouts are associated;
a controller programmed to execute the processes of:
(1A) running a game and rearrange the plurality of symbols aligned on a plurality of video reels on the display device;
(1B) determining and awarding a payout, referring to a combination of the symbols rearranged on the display device and the payout table;
(1C) determining whether or not the symbols rearranged include a predetermined type of symbol, and if the symbols include the predetermined type of symbol, fixing the predetermined type of symbol on the display device until the predetermined number of plays of the game are consumed;
(1D) running the game again and rearrange the plurality of symbols aligned on the plurality of video reels on the display device;
(1E) determining and awarding a payout, referring to a combination of the symbols rearranged on the display device in the step (1D) and the symbol fixed in the step (1C), and the payout table;
(1F) if the symbol fixed in the step (1C) and a symbol rearranged in the step (1D) in the position of the symbol fixed in the step (1C) overlap with each other in the combination of symbols for which the payout is to be awarded as the result of the step (1E), displaying and subjecting to awarding of a payout both a combination of symbols including the symbol fixed in the step (1C) and a combination of symbols including the symbol overlapped with the symbol fixed in the step (1C); and
(1G) repeating the step (1C) to (1F) until the predetermined number of plays of the game are consumed.
With the above structure, a predetermined type of symbol is accumulatively fixed, while a predetermined number of plays of a game are run. This facilitates formation of a combination including the predetermined type of symbol. Further, although the predetermined type of symbol is fixed, a symbol to be rearranged in the first place in the position where the predetermined type of symbol is fixed, as the result of rearranging a plurality of types of symbols aligned on the plurality of video reels, will be regarded as a symbol forming a combination of symbols subjected to awarding of a payout.
The gaming machine of the above aspect of the present invention may be adapted so that, in the step (1F),
if a combination of symbols including the symbol fixed in the step (1C) is not a combination for which a payout is to be awarded and if a combination of symbols including a symbol to be rearranged in the step (1D) in the position of the symbol fixed in the step (1C) is a combination for which a payout is to be awarded, the controller displays the symbol to be rearranged in the step (1D) in the position of the symbol fixed in the step (1C) in front of the symbol fixed in the step (1C).
The above structure most preferentially displays on the display device a combination of symbols for which a payout is to be awarded.
The gaming machine of the above aspect of the present invention may be adapted so that, in the step (1F),
if a combination of symbols including the symbol fixed in the step (1C) is a combination for which a payout is to be awarded, and if a combination of symbols including a symbol to be rearranged in the step (1D) in the position of the symbol fixed in the step (1C) is a combination for which a payout is to be awarded,
the controller alternately displays on the display device the combination of symbols including the symbol fixed in the step (1C), and a combination of symbols including the symbol to be rearranged in the step (1D) in the position of the symbol fixed in the step (1C).
In the above structure, if a combination of symbols including the symbol fixed in the step (1C) is a combination for which a payout is to be awarded, and if a combination of symbols including a symbol to be rearranged in the step (1D) in the position of the symbol fixed in the step (1C) is a combination for which a payout is to be awarded, both of symbol combinations are displayed.
The gaming machine of the above aspect of the present invention may be adapted so that, in the step (1F), a symbol rearranged behind the symbol fixed is partially visible.
Traditionally, when a symbol is fixed, a symbol that is supposed to be stopped in the position of the fixed symbol will be excluded in the subsequent unit games. In this structure, the player may miss a chance of winning a payout that could have been won if there was not the fixed symbol. This could lessen the player's expectation for winning of a payout.
Further, if a symbol is fixed and a part of symbol rearranged behind the fixed symbol is visible, it could further disappoint the player.
To address this, if a symbol rearranged behind the fixed symbol is partially visible, that partially visible symbol rearranged behind the fixed symbol will be regarded as a symbol forming a combination of symbols subjected to awarding of a payout.
Another aspect of the present invention is a method of controlling a gaming machine which comprises a display device configured to display a game result by rearranging a plurality of types of symbols aligned on a plurality of video reels;
a storage unit configured to store a payout table in which a plurality of symbol combinations and a plurality of payouts are associated;
a controller,
the method comprising the controller-executed steps of:
(1A) running a game and rearrange the plurality of symbols aligned on a plurality of video reels on the display device;
(1B) determining and awarding a payout, referring to a combination of the symbols rearranged on the display device and the payout table;
(1C) determining whether or not the symbols rearranged include a predetermined type of symbol, and if the symbols include the predetermined type of symbol, fixing the predetermined type of symbol on the display device until a predetermined number of plays of the game are consumed;
(1D) running a game and rearrange the plurality of symbols aligned on a plurality of video reels on the display device;
(1E) determining and awarding a payout, referring to a combination of the symbols rearranged on the display device in the step (1D) and the symbol fixed in the step (1C), and the payout table;
(1F) if the symbol fixed in the step (1C) and a symbol rearranged in the step (1D) in the position of the symbol fixed in the step (1C) overlap with each other in the combination of symbols for which the payout is to be awarded as the result of the step (1E), displaying and subjecting to awarding of a payout both a combination of symbols including the symbol fixed in the step (1C) and a combination of symbols including the symbol overlapped with the symbol fixed in the step (1C); and
(1G) repeating the step (1C) to (1F) until the predetermined number of plays of the game are consumed.
With the above method, a predetermined type of symbol is accumulatively fixed, while a predetermined number of plays of a game are run. This facilitates formation of a combination including the predetermined type of symbol. Further, although the predetermined type of symbol is fixed, a symbol to be rearranged in the first place in the position where the predetermined type of symbol is fixed, as the result of rearranging a plurality of types of symbols aligned on the plurality of video reels, will be regarded as a symbol forming a combination of symbols subjected to awarding of a payout.
Further, there is provided a gaming machine in which a symbol to be rearranged in the first place in the position where the predetermined type of symbol is fixed is regarded as a symbol forming a combination of symbols subjected to awarding of a payout.

(1D) determining and awarding a payout, referring to a combination of the symbols rearranged on the display device and the payout table;
(1E) determining whether or not the symbols rearranged include the one or more symbols selected in the step (1B), and if the symbols include the one or more symbols selected, fixing each of the one or more symbols selected on the display device until a predetermined number of plays of the game are consumed;
(1F) running again the free game and rearrange the plurality of symbols aligned on the plurality of video reels on the display device;
(1G) determining and awarding a payout, referring to a combination of the symbols rearranged on the display device in the step (1D) and the symbol fixed in the step (1E), and the payout table; and
(1H) repeating the steps (1E) to (1G) until the free game is run a predetermined number of times.
With the above structure, the one or more symbols randomly selected are accumulatively fixed, while predetermined number of plays of a game are run. This facilitates formation of a combination including the one or more randomly selected symbols.
The gaming machine of the above aspect of the present invention may further comprise: an input device that allows selection of any one or more result determination areas out of a plurality of result determination areas,

in the step (1G), executing a process of determining and awarding a payout, referring to a combination of the symbols including symbols rearranged in the selected result determination area and symbols fixed in the result determination area, and the payout table.
With the above structure, the one or more symbols randomly selected are accumulatively fixed only in the selected result determination area. This facilitates, according to the result determination area selected, formation of a combination including the one or more randomly selected symbols. Further, the one or more randomly selected symbols are not fixed in the non-selected result determination areas, which makes it possible to avoid giving an unnecessary expectation feeling to the player.
The gaming machine of the above aspect of the present invention may further comprise:
an additional bet device configured to enable placement of an additional bet which leads to awarding of a further play of the free game in addition to the predetermined number of plays of the free game, if a predetermined condition is satisfied as the result of the normal game.
wherein the controller

There is provided a gaming machine configured to fix-display a predetermined symbol on the display and provide sufficient period for formation of a combination of symbols including the predetermined symbol, thereby enhancing the player's expectation for winning of a payout.
The following will describe a gaming machine of the present invention with reference to figures.
The present embodiment deals with an example where the gaming machine is a slot machine configured to run a game which awards a benefit based on a combination of a plurality of symbols rearranged in a result determination area selected.
Specifically, the slot machine includes: an input device (control panel 30 and the like) which enables selection of any result determination area out of a plurality of result determination areas (WAYS BET1, WAYS BET2, WAYS BET3, WAYS BET4, WAYS BET5), a storage unit (RAM 73) configured to store a total counter that keeps track of the game play count which is incremented upon start of the game, for each of the plurality of result determination areas, and further store a threshold game play count for a special game awarding a benefit (15-choice pick game as a special game), for each of the plurality of result determination areas, and a controller (main CPU 71, ROM 72, RAM 73 and the like) programmed to perform the following steps.
The steps are specifically as follows. Namely, a selection of a result determination area is received via the input device of the slot machine, and a normal game is run which awards a benefit based on a combination of a plurality of symbols rearranged in a result determination area selected (S1). When a free game trigger is established in the normal game (S2), one or more fix symbols which or each of which is a symbol to be fixed in the result determination area in the free game is selected (randomly selected) (S3). Then, in the free game, the fix symbols are accumulatively fixed in the result determination area in which the first fix symbol is fixed (S4). When the free game results in a re-trigger (S5), awarding of a payout (S6), or no-payout (S7), and if the free game is yet to be repeated, the free game is run again. When the free game is repeated up to a given number of times, the free game is terminated (S8). Then, whether or not a re-trigger has occurred during the free game is determined (S9). If a re-trigger has occurred, the fix symbols are again selected (S3).
Further, as the result of the normal game, if the number of plays of the normal game reaches a threshold game play count (ceiling number) (S11), a 15-choice pick game (corresponding to a special game) is run, and a fixed payout is awarded (S12).
Then, in S9, if there is no re-trigger, or after the 15-choice pick game in S12, the number of times the normal game is played is reset (S10). Then, the state returns to the normal game (S1).
The slot machine is a type of a gaming machine. While the present embodiment deals with the slot machine as an example of the gaming machine, the slot machine may be a different type of machine on condition that a normal game can be individually run by the machine and a free game developing from the normal game can be run by the machine.
A normal game of the present embodiment is run by the slot machine. The normal game is a slot game of rearranging symbols.
The symbols encompasses “MAN”, “DRAGON”, “FISH”, “TURTLE”, “GOURD”, “ACE”, “KING”, “QUEEN”, “JACK”, “TEN”, “NINE”, “WILD”, and “FEATURE”.
A coin, paper money, or electrically valuable information corresponding to these is used as a game value. Note that the gaming value in the present invention is not particularly limited. Examples of the gaming value include game media such as medals, tokens, cyber money, tickets, and the like. A ticket is not particularly limited, and a later-mentioned barcoded ticket may be adopted for example.
The free game of the present embodiment may be any type of game on condition that the gaming state thereof is different from that of the normal game. The free game is a game which is executable with a smaller amount of game values bet than in the normal game. Note that “bet of fewer amounts of gaming values” encompasses a bet of zero gaming value. The “free game” therefore may be a game runnable without a bet of a gaming value, which free game awards an amount of gaming values based on symbols rearranged. In other words, the “free game” may be a game which is started without consumption of a gaming value. To the contrary, the “normal game” is a game runnable on condition that a gaming value is bet, which normal game awards an amount of gaming value based on the symbols rearranged. In other words, the “normal game” is a game which starts with consumption of a gaming value. Further, the “free game” is a game to which transition occurs when a predetermined condition (free game trigger) is satisfied in the normal game.
The term “rearrangement” indicates that the symbols are rearranged after the arrangement of the symbols is dismissed. The term “arrangement” indicates a state in which the symbols are visually recognizable by an external player.

Subsequently, as the rotation of the symbol array of each video reel is stopped, the slot machine determines whether the combination of the symbols displayed for the player is a combination related to win.
<Payout>
When the combination of the symbols displayed for the player is a combination related to win, the slot machine offers, to the player, benefit according to the combination. For example, when a combination of symbols related to a payout of coins has been displayed, the slot machine pays out coins of the number corresponding to the combination of symbols to the player.
When a combination of symbols associated with a free game trigger is displayed, the slot machine starts the free game. In the embodiment of the present invention, as the free game, a game (free game) which executes the random determination of the symbols to be stopped a predetermined number of times without consumption of coins.
When a combination of symbols associated with a jackpot trigger is displayed, the slot machine may pay out coins corresponding to a jackpot amount to the player. As the jackpot, at least one of the coins consumed by the player at each slot machine is accumulated as a jackpot amount, and when the jackpot trigger is established at a slot machine, coins corresponding to the accumulated jackpot amount is paid out to that slot machine. In the present case, the slot machine calculates an amount (accumulative amount) accumulated to the jackpot amount each time the game is played, and sends the calculation result to an external controller. The external controller adds the accumulative amount sent from each slot machine to the jackpot amount.
In addition to the above, the slot machine may have other benefits such as mystery bonus, in addition to the benefit above. In the mystery bonus, a predetermined number of coins are paid out when a win is achieved in dedicated random determination. When a spin button is pressed, the slot machine samples a random number for the mystery bonus, and whether a mystery bonus trigger is established is randomly determined.
A rescue function built in the present embodiment is a function for rescuing the player from a situation of not being able to play the free game for a long period of time (a function of awarding a return (rescue) to a player, if a predetermined benefit is not awarded in a predetermined number of plays of a game). In the embodiment of the present invention, the administrator of the slot machine is able to select whether rescue is active or inactive. When the rescue is activated, the slot machine starts to count the number of plays of the game played. When the counted number of plays of the game played reaches a predetermined number without awarding of a large amount of payout in the free game and the like, the slot machine awards a predetermined benefit.
<Determination of Effect>
The slot machine produces an effect by displaying an image on a display, outputting light from a lamp, and outputting sound from a speaker. The slot machine samples an effect-use random number and determines the content of an effect based on randomly determined symbols or the like.

Now, referring to
A gaming board 50 is provided with a CPU 51, a ROM 52, and a boot ROM 53, which are mutually connected by an internal bus; a card slot 55 corresponding to a memory card 54; and an IC socket 57 corresponding to a GAL (Generic Array Logic) 56.
The memory card 54 includes a nonvolatile memory, and stores a game program and a game system program. The game program includes a program related to game progression, a random determination program, and a program for producing effects by images and sounds (see e.g.,
The random determination program is a program for randomly determining to-be stopped symbol on the video reels 3. The to-be stopped symbol is data for determining three symbols to be displayed to the symbol display area 4 out of plural symbols forming each symbol array. The slot machine 1 of the embodiment of the present invention determines, as the symbols to be stopped, the symbols to be displayed in a predetermined area (e.g. the uppermost stage) out of the three areas provided for each of the video reels 151-155 of the symbol display area 4. This way symbols to be displayed in the three areas (the upper stage area, the middle stage area, and the lower stage area) corresponding to each video reel 3 of the symbol display area 4.
The aforementioned random determination program includes symbol determination data. The symbol determination data is data that specifies random numbers so that each of the symbols forming the symbol array is determined at an equal probability for each of the video reels 3. For example, for the 1st video reel (“Reel 1”) 3a of the normal game video reel 3 shown in
While in the embodiment of the present invention the data is arranged to differentiate the number of symbols constituting the symbol array between the video reels 3 (29 symbols for the video reel 3a, 29 symbols for the video reel 3b, 28 symbols for the video reel 3c, 27 symbols for video reel 3d, and 34 symbols for the video reel 3e), the number of symbols constituting the symbol column may be identical between the video reels 3. For example, each of all symbol arrays of the video reels 3a to 3e of the video reels 3 may be constituted by 50 symbols. This arrangement increases the degree of freedom in setting the probabilities of the selection of the symbols of different types in each video reel 3.

[Arrangement of Symbol Combination Table]
Now, symbol combination tables will be described with reference to
The symbol combination tables of the present embodiment define the combinations of symbols (the number of symbols) with which a win is achieved and payout amounts. In the slot machine 1, a win is achieved when the scroll of the symbol array of each video reel 3 is stopped and symbols displayed in the symbol display area 4 forms a line which goes through the 1st column area to the 5th column area within the result determination area set to be the subject of the result determination by the WAYS BET. In accordance with the type of win, a benefit such as the payout of coins is awarded to the player.
Basically, a win is achieved when a predetermined number of symbols of a single kind are arranged linked to one another, as in a 3-of-a-kind, 4-of-a-kind, or a 5-of-a-kind combination, through the 1st column area to the 5th column area, within the result determination area set as the subject to result determination, by the WAYS BET button. The above symbols of a single kind may be “MAN”, “DRAGON”, “FISH”, “TURTLE”, “GOURD”, “ACE”, “KING”, “QUEEN”, “JACK”, “TEN”, or “NINE”. The symbol of “WILD” is substituted by any of the above symbols: “MAN”, “DRAGON”, “FISH”, “TURTLE”, “GOURD”, “ACE”, “KING”, “QUEEN”, “JACK”, “TEN”, or “NINE”. Regarding the “FEATURE” symbol, a payout and the right to play the free game are awarded if “FEATURE” symbol occurs in three or more consecutive positions through the 1st column area to the 5th column area (when 3 or more-of-a-kind combination of the “FEATURE” is formed), irrespective of the area turned active by the ways bet button.
For example, when the “WAYS BET5” is selected, all the areas out of the symbol display area 4 are subjected to result determination (activated). When the scroll of the symbol arrays on the video reels 3 is stopped and the “DRAGON” symbol occurs in the lower stage of the 1st column area, the upper stage of the 2nd column area, the upper stage of the 3rd column area, the middle stage of the 4th column area, and the lower stage of the 5th column area, there is a win in which the symbol occurs in five linked positions from the 1st column area to the 5th column area (5-of-a-kind combination of “DRAGON” is formed). In this case, the symbol combination table shown in
Further, for a win related to “MAN”, “DRAGON”, “FISH”, “TURTLE”, “GOURD”, “ACE”, “KING”, “QUEEN”, “JACK”, “TEN”, or “NINE”, a product of the value associated with the credit type of the unit game multiplied by the value defined in the symbol combination table is paid out. For example, when a win related to three “DRAGON” symbols is achieved (when 3-of-a-kind combination of “DRAGON” is formed in a unit game where 10 bet is placed by the 10-BET button 40, the awarded credits will be 35×10=350. Further, for a win related to “FEATURE”, a product of all the bet amount in the unit game multiplied by the value defined in the symbol combination table is paid out. For example, when a win related to three “FEATURE” symbols occurs in a case where a result determination area to be subjected to result determination is set by the ways bet5 button 47 (which requires 30 credits) and 10 credits are placed as a bet by the 10-bet button 40, 1500 credits (30×10×5=1500) and the right to play the free game are awarded.
(Total Counter Capable of Counting Plays of Game for Each WAYS BET)
As shown in
As described, the game play count on the total counter corresponding to the selected WAYS BET (6 types of WAYS BET with different result determination areas, which are ways bet1, ways bet2, ways bet3, ways bet4, ways bet5, and ways bet5+feature boost, in the present embodiment) is incremented upon start of the normal game, and a benefit is awarded when the game play count on the total counter reaches the threshold game play count. With the total counter which keeps track of the game play count provided independently of the other counters, for each of the plurality of result determination areas, variation is given to the WAYS BET (result determination areas) to be selected by the player.
(Credit Type Counter Configured to Perform Counting for Each Credit Type)
In the present embodiment, a credit type counter is set in the RAM 73, which keep track of game play count counted by the total counter set for each WAYS BET, for each of the credit types (5 types of credit types with different credit values, which are 1BET, 2BET, 3BET, 5BET, and 10BET). Specifically, for each of the 6 types of ways bet associated with different result determination areas, i.e., ways bet1, ways bet2, ways bet3, ways bet4, ways bet5, and ways bet5+feature boost, there are 5 types of credit type counters corresponding to the 5 types of credit types: i.e., 1bet, 2bet, 3bet, 5bet, and 10bet. For example, as shown in the credit type counters of WAYS BET5 shown in

[Contents of Program]
Now, the program to be executed by the slot machine 1 is described with reference to
(Main Control Process)
First, with reference to
First, when the slot machine 1 is powered on, the main CPU 71 reads an authenticated game program and a game system program from a memory card 54 via a gaming board 50, and then write them in the RAM 73 (Step S11).
Next, the main CPU 71 executes an initializing process at the end of each round of the game (Step S12). This process clears data in a working area of the RAM 73, which becomes unnecessary at the end of each round of game, e.g., the amount of bet, symbols randomly determined, and the like.
Next, the main CPU 71 executes a start-check process described later with reference to
Next, the main CPU 71 executes a symbol random determination process (S14). In this process, symbols to be stopped are determined based on random numbers for symbol determination.
Specifically, the main CPU 71 first samples random numbers for symbol determination. The main CPU 71 then randomly determines symbols to be stopped on the video reels 3 (3a, 3b, 3c, 3d, 3e). The main CPU 71 executes random determination for each of the video reels 3 (3a, 3b, 3c, 3d, 3e), and determines any one of the symbols as the symbols to be stopped. The symbols are determined at equal probabilities. The main CPU 71 stores the symbols determined as to stop on each video reel 3 in a symbol storing area in the RAM 73.
The main CPU 71 then executes an effect contents determination process (S15). The main CPU 71 samples an effect-use random number and randomly determines any of a plurality of predetermined contents of effect.
Next, the main CPU 71 executes a symbol display control process (step S16). In the process, the scroll of the symbol array on each video reel 3 is started, and the symbols determined as the symbols to stop in the symbol random determination process of S14 are stopped at a predetermined positions (e.g. the upper area in the symbol display area 4). That is, 15 symbols including the symbols to be stopped are displayed in the symbol display area 4. For example, the symbol with the code number “10” is to be stopped in the middle stage area, the symbols with the code numbers “9” and “11” are displayed in the upper stage and the lower stage of the symbol display area 4, respectively.
Next, the main CPU 71 executes a payout amount determination process (step S17). In this process, a symbol combination table (see
Next, the S18 executes a payout process (step S18). The main CPU 71 adds a value stored in the payout storage area to a value stored in the credit counter stored in the credit amount storage area provided in the RAM 73.
Next, the main CPU 71 determines whether or not a free game trigger is met (S19). In the present embodiment, the trigger for transition to the free game is the “FEATURE” symbol occurs in three or more consecutive positions through the 1st column area to the 5th column area, irrespective of the area activated by a ways bet button. The main CPU 71, when determining that the free game trigger has been established (S19: Yes), executes a later described free game process (step S20)
Next, the main CPU 71, when determining that the free game trigger is not established in the step S19 (S19: NO), executes the mystery feature random determination process (S21). In the mystery feature random determination process, a random number is sampled to determine whether or not the mystery feature results in the win or not win, based on the mystery feature random determination table (see
Next, the main CPU 71 determines whether or not the mystery feature is won (S22). If the mystery feature is won (S22: YES), the later-described 15-choice pick game process is executed (S24).
On the other hand if the mystery feature is not won (S22: NO), whether or not the value on the total counter counted in the game play count process (later-described S49) in the start-check process has reached the threshold game play count of 450 (S23). If the value on the total counter has not yet reached the threshold game play count of 450 (S23: NO), the process transits to S12.
On the other hand, when the value of the total counter has reached the threshold game play count of 450 (S23: YES), the lather-described 15-choice pick game process is executed (S24).
Next, after the free game process of S20 or after the 15-choice pick game process of S24, the values of the total counter and the values on the credit type counters are reset (bring them back to “0”) (S25).
For example, after the free game process of S20, or if the 15-choice pick game process is executed by the mystery feature resulting in the win, the resetting is done only for the total counter of WAYS BET for which a bet has placed in the start-check process of S13. For example, if a bet is placed for ways bet5 in the start-check process of s13, the total counter corresponding to the ways bet5 is reset, and the other total counters for ways bet1, ways bet2, ways bet3, ways bet4, and ways bet5+feature boost are maintained. At the same time, the credit type counters corresponding to the WAYS BET for which a bet has been placed in the start-check process of S13 are reset.
Further, if the 15-choice pick game process is executed after the value of the total counter for ways bet5 has been determined as to reached the threshold game play count in S23, only the total counter corresponding to the WAYS BET5 is reset, and the other total counters for ways bet1, ways bet2, ways bet3, ways bet4, and ways bet5+feature boost are maintained. At the same time, the credit type counters corresponding to the WAYS BET whose total counter's value has reached the threshold game play count are reset.
As described, when the value of the total counter (game play count) reaches the threshold game play count, a benefit is awarded. At the same time, while the total counter of the particular WAYS BET (result determination area) whose value has reached the threshold game play count is reset, the other total counters of the other WAYS BET (result determination area) whose value has not yet reached the threshold game play count are maintained. This induces the player to select the WAYS BET in which the value of the total counter has not yet reached the threshold game play counts.
Further, if the free game trigger occurs in the normal game, the free game is run and only the value of the total counter corresponding to the selected WAYS BET (result determination area) is reset, while the values of the other total counters of the other WAYS BET are maintained. This induces the player to select the WAYS BET in which the value of the total counter has not yet reached the threshold game play counts.
After S25, the process transits to the step S12.
(Start-Check Process)
Next, the start-check process is described reference to
First, the main CPU 71 reads a barcode attached ticket 175 through the bill entry 115, and determines if there is an addition of a credit (step S41). When determining that there is addition of a credit (S41: YES), the main CPU 71 adds the specified amount of credits to the value stored in the credit counter stored in the credit amount storage area of the RAM 73 (step S42). It should be noted that the subject to be read by the bill entry 115 includes paper money, an IC card and the like, in addition to the barcode attached ticket 175.
After the step S42 or when determining in the step S41 that there is no addition of credits (S41: NO), the main CPU 71 determines whether or not the value stored in the credit counter stored in the credit amount storage area is 0 (step S43). The process then transits to the step S41, if the value stored in the credit counter stored in the credit amount storage area is 0 (S43: YES).
On the other hand, when the main CPU 71 determines that the value stored in the credit counter stored in the credit amount storage area is not 0 (S43: NO), the main CPU 71 enables operation of the ways bet buttons (ways bet1 button 43, ways bet2 button 44, ways bet3 button 45, ways bet4 button 46, ways bet5 button 47, feature boost button 48) and the bet buttons (1-bet button 34, 2-bet button 35, 3-bet button 37, 5-bet button 39, 10-bet button 40) (step S44). By selecting any of the five stages of ways bet buttons, a result determination area to be subjected to result determination is selected out of 15 areas of the 5 by 3 matrix of the symbol display area 4 (see FIG. 6).
Next, the main CPU 71 determines if an operation of the ways bet button or the bet button is detected (step S45). When the main CPU 71 detects pressing of the ways bet button by the player through the ways bet switch (ways bet1 switch 43S, ways bet2 switch 44s, ways bet3 switch 45s, ways bet4 switch 46s, ways bet5 switch 47s, feature boost switch 48s) and detects pressing of the bet button by the player through the bet switch (1-bet switch 34S, 2-bet switch 35S, 3-bet switch 37S, 5-bet switch 39S, 10-bet switch 40S), the main CPU 71 updates the value of the bet counter stored in the bet amount storage area provided in the RAM 73, based on the product of the amount of credit necessary for the selected ways bet (1 credit for ways bet1, 5 credits for ways bet2, 10 credits for ways bet3, 20 credits for ways bet 4, 30 credits for ways bet5, and 40 credits for ways bet5+feature boost) multiplied by the amount of credit corresponding to the bet button operated (step S46).
After step S46 or when no operation of the ways bet button or the bet button is detected in step S45 (S45: NO), the main CPU 71 enables operation of the spin button 49 (S47).
After the step S47, the main CPU 71 determines whether or not an operation of the spin button 49 is detected (step S48). When the main CPU 71 determines that an operation of the spin button 49 is not detected (S48: NO), the process moves to the step S44.
On the other hand, when the main CPU 71 determines that the operation of the spin button 49 has been detected (S48: YES), the game play count process is executed (step S49). In the game play count process, the game play count on the total counter (see
Further, in the game play count process, the game play count on the credit type counter corresponding to the credit type and the ways bet determined as to be operated in the step S45 is incremented by 1. For example, suppose an operations on the ways bet5 and the credit type of 3BET are detected in S45, and that the value on the credit type counter of the 3BET of the ways bet5 is 20 (see
After the step S49, the main CPU 71 subtract the value on the bet counter calculated in the step S46, from the value stored in the credit counter stored in the credit amount storage area (step S50). Then, the start-check process is terminated.
(Free Game Process)
The following describes a free game process with reference to
First, the main CPU 71 determines whether or not the feature boost function is in the on state (S101). Specifically, in the step is determined whether or not the feature boost function is turned on by operating the feature boost button 48 in the start-check process of the step S45.
If the feature boost function is not in the on state (in the off state: S101: NO), a value of 5 is added to a free game play counter stored in the RAM 73 (S102). If the feature boost function is in the on state (S101: YES), a value of 6 is added to the free game play counter of RAM 73 (S103). As described, if the feature boost function is in the off state, there will be awarded five plays of the free game. This number of plays of the free game awarded will be increased by one and six plays of the free game in total will be awarded, if the feature boost function is in the on state.
After the step S102 or S103, the main CPU 71 executes a fix symbol random selection process (S104). Specifically, in the fix symbol random selection process, there will be five coins 201 displayed on the lower image display panel 141 as shown in
Next, the main CPU 71 executes the at-one-game-end initialization process (S105) in the same manner as the step S12. Next, the main CPU 71 executes a symbol random determination process (S106) in the same manner as the step S14.
The main CPU 71 then executes the effect contents determination process (S107) in the same manner as the step S15. Next, the main CPU 71 executes the symbol display control process (S108) in the same manner as the step S16. The main CPU 71 then executes the payout determination process (S109) in the same manner as in the step S17.
Subsequently, the main CPU 71 executes a payout process (step S110). In this payout process, the main CPU 71 adds the value stored in a payout counter in the payout determination process of the step S109 to the value stored in a free game payout counter. The free game payout counter is an area where the total payout amount determined during the free game is stored. When the free game process ends, the main CPU 71 adds the value stored in the free game payout counter to a credit amount counter provided in the RAM 73. In other words, the total payout amount determined in the free game is awarded at once. The payout may be awarded by ejecting coins from the coin payout exit 15A or by issuing a ticket with a barcode.
It should be noted that in the free game, the ways bet and the credit type in the normal game in which the right to play the free game is awarded is inherited.
Next, the main CPU 71 determines whether or not a re-trigger occurred (S111). In the present embodiment, the re-trigger occurs when the symbol of “FEATURE” occurs in three or more consecutive positions through the 1st column area to the 5th column area, irrespective of the result determination area activated by the ways bet. When it is determined that the re-trigger occurred (S111: Yes), the main CPU 71 adds 1 to a value of a feature stock counter in the RAM 73 and updates the value of the same (S112).
Next, when it is determined that the re-trigger did not occur (S111: NO) or after the step S112, the main CPU 71 determines whether or not a fix symbol 210 determined in the fix symbol random selection process of S104 stopped in the result determination area activated by the ways bet button includes (S113).
If the fix symbol 210 is stopped (S113: YES), the fix symbol 210 is fixed in the result determination area where it is stopped (the state where the fix symbol is stopped is maintained. see
Next, if it is determined that the fix symbol 210 is not stopped in the step S113, or after the step S114, the main CPU 71 subtract 1 from the value stored in the free game play counter (S115).
The main CPU 71 then determines whether the value on the free game play counter is 0 (S116). When determining that the value on the free game play counter is not 0 (S116: NO), the main CPU 71 proceeds to the step S105.
In the meanwhile, when the value on the free game play counter is 0 (S116: YES), all the fix symbols 210 fixed in the result determination area are unfixed (S117). Subsequently, the main CPU 71 subtracts 1 from the number on the feature stock counter (step S118).
The main CPU 71 then determines whether the value on the feature stock counter is 0 (step S119). When determining that the value on the feature stock counter is not 0 (S119: NO), the main CPU 71 proceeds to the step S101. In the meanwhile, when the value on the feature stock counter is 0 (S119: YES), the free game process is terminated.
With the above structure, the fix symbol 210 is accumulatively fixed, while the free game is run 5 times or 6 times. This facilitates formation of a combination including the fix symbol 210. Further, although the fix symbol 210 is fixed, a symbol 211 to be rearranged in the first place in the position where the fix symbol 210 is fixed, as the result of rearranging a plurality of types of symbols aligned on the plurality of video reels 3, will be regarded as a symbol forming a combination of symbols subjected to awarding of a payout.
With the above structure, the one or more fix symbols 210 randomly selected are accumulatively fixed only in the selected ways bet (result determination area). This facilitates, according to the ways bet (result determination area) selected, formation of a combination including the one or more randomly selected fix symbols 210. Further, the fix symbols 210 randomly selected by the fix symbol random selection process are not fixed in the non-selected ways bet, which makes it possible to avoid giving an unnecessary expectation feeling to the player.
Turning on the feature boost function (placing an additional bet) may increase (from the 5 plays in the normal occasion to 6 plays) the number of plays of the free game awarded when the free game trigger occurs as the result of the normal game. With the above structure, the one or more fix symbols 210 randomly selected in the fix symbol random selection process are accumulatively fixed, while the increased number of plays of the game are run. This further facilitates formation of a combination including the one or more randomly selected fix symbols 210.
(15-Choice Pick Game Process)
Now, referring to
First, the main CPU 71 executes a pick game introduction effect process (S131). In this pick game introduction effect, as shown in
Next, the main CPU 71 executes a later described pick game payout rate determination process (S132).
Specifically, if the transition to the 15-choice pick game process occurred after the value on the total counter reaches the threshold game play count of 450 in the process of S23, the payout rate random determination table determination table is created (see
As shown in
Subsequently executed is the payout rate random determination table random determination, which determines the payout rate random determination table, based on the payout rate random determination table determination table after it is created. In this process, one payout rate random determination table is selected out of the payout rate random determination table 1bet, the payout rate random determination table 2bet, the payout rate random determination table 3bet, the payout rate random determination table 5bet, the payout rate random determination table 10bet, based on the probability of being randomly selected in the payout rate random determination table determination table (see
Next, a payout rate random determination for determining the payout rate is executed, based on the payout rate random determination table determined through the random determination of the payout rate random determination table. In this process, a level (payout rate) is determined based on the payout rate random determination table shown in
Next, each amount of payout in the special game basic payout table determination table shown in
It should be noted that, when the transition to the 15-choice pick game occurs after the mystery feature is won in the step S22, the payout rate random determination table corresponding to the credit type used for placing a bet at the time of winning the mystery feature is automatically selected. For example, if the credit type used in the bet is 1bet, the payout rate random determination table 1bet is selected. If the credit type used in the bet is 2bet, the payout rate random determination table 2bet is selected. If the credit type used in the bet is 3bet, the payout rate random determination table 3bet is selected. If the credit type used in the bet is 5bet, the payout rate random determination table 5bet is selected. If the credit type used in the bet is 10bet, the payout rate random determination table 10bet is selected.
Then, based on the selected payout rate random determination table (see
In the above, the pick game payout rate determination process of the step S132 is described. Following the pick game payout rate determination process of the step S132, a 15-choice display process is executed (S133).
As shown in
Next, the main CPU 71 determines whether or not any of the 15 pouches 221 displayed on the lower image display panel 141 is selected (S134). If no pouches are selected (S134: NO), an input of a selection is waited.
On the other hand, when any of the 15 pouches 221 is selected (S134: YES), a selection effect process (S135) is executed. Through the selection effect process, a jewel associated with the selected one of the 15 pouches 221 is displayed. For example, as shown in
Next, the main CPU 71 determines whether or not the player has selected 3 red jewels 231, 3 blue jewels 232, 3 green jewels 233, 3 amber jewels 234, or 3 purple jewels 235 (S136).
If 3 of the same type of the jewels are selected (S136: Yes), a win effect process is executed (S139). In this win effect process, the indicator corresponding to the type of jewels, 3 of which have been selected by the player, is lighted to emphasize the jewel type having been obtained. For example, as shown in
On the other hand, none of the types of jewels are selected up to 3 (S136: NO), the main CPU 71 determines if any 2 of the same type of jewels, 2 of the red jewels 231, 2 of the blue jewels 232, 2 of the green jewels 233, 2 of the amber jewels 234, 2 of the purple jewels 235 are selected (S137)
If 2 of the same type of the jewels are selected (S137: Yes), a Lizhi effect process is executed (S138). In the Lizhi effect process, there will be an effect that informs the player that there will be one to go before selecting 3 of the same type of jewels (Lizhi state). Specifically, in the effect, the tempo of the music (BGM) played during the 15-choice pick game process is played in a faster tempo.
If none of the types are selected up to 2 (S137: NO), or after the step S138, the process transits to S134.
Next, after the step S139, the main CPU 71 executes a payout process (S140). In this payout process, the payout amount is determined, based on the payout table created in the step S132 and the type of jewels, all 3 of which have been selected by the player in the above process. For example, in a case where: the payout rate determined by the random determination of the payout rate is ×10; the total counter whose value has reached the threshold game play count corresponds to ways bet1; and 3 amber jewels are obtained in the 15-choice pick game, the basic payout awarded will be 20×10=200 credits.
After the above process, the 15-choice pick game process is terminated.
In the structure, the plurality of types of ways bet (result determination areas) are associated with the plurality of special game basic payout tables in the special game basic payout table determination table. Therefore, it is possible to adjust an expectation value for the payout by the relation between each type of ways bet to be selected by the player and the special game basic payout table to be the reference for the payout in the 15-choice pick game. As such, it is possible to set the expectation value for the payout of the 15-choice pick game according to the ways bet selected by the player, and ensure the fairness of the payouts in the 15-choice pick game.
With the above structure, the payout rate random determination table determination table is created according to the usage counts of each of the credit types at a time the value of the total counter reaches the threshold game play count. Then, based on the payout rate random determination table determination table created, the payout rate random determination table is determined, and random determination is executed for determining the payout rate in the 15-choice pick game based on the payout rate random determination having been determined. In this payout rate random determination, there is executed a random determination corresponding to the usage counts of each of the credit types at a time the game play count reaches the threshold game play count. That is, the usage count of each credit type at a time the value of the total counter reaches the threshold game play count affects determination of the payout rate in the 15-choice pick game. Therefore, each bet placed until the value of the total counter reaches the threshold game play count is not wasted, which ensures the fairness in the 15-choice pick game.
[Screen Display Specification]
Now, the screen display specification of the slot machine 1 will be described with reference to
<Screen Display Specification in Normal State>
To begin with, screen display specification in the normal game will be described with reference to
As shown in
On the lower image display panel 141 in the normal game, in addition to the above-described symbol display area 4, a credit meter 404, a bet meter 405, a win meter 406, a display area 407 for ways bet information, bet information and the game state, a graph-switch button 400, a feature boost display area 420, a help touch button 409, a language switching touch button 410, a sound volume switching touch button 411, and a denomination indicator 412. In the credit meter 404 is displayed a remaining credit amount. The default value is 0. In other words, a credit amount stored in the RAM 73 is displayed. The bet meter 405 displays the total bet amount of the current game (or the final game). The win meter 406 displays the total credit amount of win and the detail of the win. The feature boost display area 420 displays a red-flamed logo of “FEATURE BOOST”, when the feature boost function is turned on (when the feature boost function is in the off state, the logo is displayed with a blue flame).
The display area 407 for the ways bet information, bet information and the game state displays the ways bet information and the bet information of the currently played game (or the final play of the game). Specifically, the area displays which type of the 5 staged ways bet (i.e., ways bet1, ways bet2, ways bet3, ways bet4, and ways bet5) is currently selected. Further, the display area 407 displays the state of the currently played game. The area is hidden while the current play of the game is played. When the current game state is game over, “GAME OVER” is displayed. When the current game state is waiting for gamble, “PLAY ON, GAMBLE or TAKE WIN” is displayed.
The graph-switch button 400 sequentially changes the display every time it is touched by the player, in the order of a normal screen (title logo screen)→a line-graph G1, →a bar-graph G2, →a block-graph G3, →and back to the normal screen (title logo screen).
When the player touches the help touch button 409, the first page of the help screen is displayed on the lower image display panel 141. The help touch button 409 is darkened when it is inactive, e.g., during the rotation of the video reels 3.
As the language switching touch button 410 is touched by the player, the language is switched to English or Chinese. The language switching touch button 410 is activated only during the advertisement, and is darkened when it is inactive, e.g., during the rotation of the video reels 3. Furthermore, on the language switching touch button 410, the displayed national flags are changed to “U.K./Chine” or “U.S.A./China” in accordance with the setting of the AUDIT. When the language switching is set at “DISABLE”, the language switching touch button 410 is changed to a paytable button with which a payout table is displayed on the help screen.
The sound volume switching touch button 411 is used for switching the game sound volume in three stages. Each time the sound volume switching touch button 411 is touched by the player, the game sound volume is switched such that, for example, from low to middle to high to small to middle. The denomination indicator 412 displays current denomination.
<HELP Screen Display Specification>
Next, the following describes HELP screen display specification, with reference to
As the lower image display panel 141 shown in
When the player touches the exit touch button 414, the HELP screen 413 disappears from the lower image display panel 141 and a normal game screen (see
[Win Effect]
Now, a win effect in the slot machine 1 will be described with reference to
The win effect is an effect executed when a win is achieved in the normal game or the free game. In other words, the effect is executed when symbols stopped in the result determination area subjected to result determination by operating the ways bet button forms a combination of a predetermined number of symbols which are linked within the 1st column area to the 5th column area in the symbol display area 4, the combination matching with a symbol combination on the symbol combination table (see
<Flow of Win Effect>
To begin with, as shown in
On the lower image display panel 141, the win effect is performed for the achieved win. The win effect is provided when the feature symbol occurs to three or more consecutive positions through the 1st column area to the 5th column area, followed by a win effect associated with a win related to the other symbols are executed. In this regard, for symbols for each of which a win animation is prepared, an animation effect is carried out. The symbols which do not relate to any win are darkened to be less noticeable.
For example, as shown in
Subsequently, as shown in
When one kind of symbols successively appear, as shown in
<Win Signboard>
Now, the win signboard will be described with reference to
The total win amount as a result of the current play of the game is displayed on a silver signboard 421 shown in
On the other hand, when the increment amount becomes more than 50 times as much as the bet amount, the gold signboard 421 shown in the upper part of
<Effect Sound when Three or More “FEATURE” Symbols Appear>
Now, effect sound when three or more “FEATURE” symbols appear will be described with reference to
When three or more “FEATURE” symbols appear in the symbol display area 4, dedicated “Jilililili” sound (bell-ring like sound) is reproduced as a sound effect. The sound reproduction starts when all reels stop, and lasts three seconds until the increment starts after 30 frames elapse. During the reproduction of the bleep sound, the symbol animation, the display of the LINE WIN, and the increment display are not performed.
According to the embodiment of the present invention, as shown in
After the three seconds, as shown in
[Free Game Introduction Effect]
Now, referring to
As shown in
Then, as shown in
[Fix Effect of Fix Symbol in FREE GAME]
Now, referring to
Then, as shown in
[Effect when Free Game Ends]
The following describes an effect at the end of the free game in the slot machine 1, with reference to
As shown in
Thereafter, a dark change image is displayed as shown in
[Re-Trigger Effect]
Now, the re-trigger effect executed when the re-trigger is established in S111 will be described with reference to
When the “FEATURE” symbol occurs in three or more consecutive positions through the 1st column area to the 5th column area, irrespective of the area activated by a ways bet button, a message reading “RETRIGGER” is displayed on the lower image display panel 141, as shown in
Then, when all the given plays of the free game are finished (when the value on the free game play counter is determined as to be 0 in the step S116), 1 is subtracted from the value on the feature stock counter 430. For example, as shown in
Further, as shown in
It should be noted that, as shown in
[Win Effect: When Fix Symbol is Involved]
As shown in
As shown in
As shown in
As shown in
As described, even if the fix symbol 210 is fixed, a combination for which a payout is awarded is preferentially displayed in the symbol display area 4.
Further, if a combination of symbols including the fix symbol 210 is a combination for which a payout is to be awarded, and if a combination of symbols including a symbol 211 rearranged in the position of the fix symbol 210 is a combination for which a payout is to be awarded, both of symbol combinations are displayed.
Further, traditionally, when a fix symbol 210 is fixed, a symbol 211 that is supposed to be stopped in the position of the fixed symbol 210 will be excluded in the subsequent unit games. In this structure, the player may miss a chance of winning a payout that could have been won if there was not the fix symbol 210. This could lessen the player's expectation for winning of a payout. Further, if a fix symbol 210 is fixed and a part of the symbol 211 rearranged behind the fixed symbol is visible, it could further disappoint the player for winning the payout.
In view of that, when the symbol 211 rearranged behind the fix symbol 210 is partially visible, that partially visible symbol 211 is also regarded as a symbol forming a combination of symbols subjected to awarding of a payout.
[Free Game Introduction Effect, when Feature Boost Function is on]
Referring to
The above described effect in the fix symbol random selection process of the step S104 is also displayed on the lower image display panel 141 when the feature boost function is turned on. Specifically, 5 coins 201 are displayed on the lower image display panel 141. These 5 coins 201 are randomly associated with any of the symbols of “MAN”, “DRAGON”, “FISH”, “TURTLE”, and “GOURD”, respectively. Then, a message is displayed to the player, which reads “SELECT ONE COIN. WHEN A CERTAIN SYMBOL OCCURS ON A REEL DURING THE FREE GAME, IT WILL BE FIXED UNTIL THE END OF THE FREE GAME.” When the player picks a coin 201 out of those displayed on the lower image display panel 141 through the touch panel 114, the symbol associated with the selected coin 201 is lighted to make it noticeable as a fix symbol 210, as shown in
Then, as shown in
[Pick Game Introduction Effect]
The following describes an effect at the time of 15-choice pick game process, with reference to

Now, button prereading in the slot machine 1 will be described with reference to
To be more specific, as shown in
The prereading function of prereading the pressing of the button is active only in a normal game in which no win occurs. The prereading function is inactive in a game in which a win occurs. By setting the AUDIT, the prereading function is activated or disabled. In other words, the priority is arranged as Setting>Hardware setting>Control panel. The prereading function is usually activated. The function is disabled in USA.
The button prereading function is active only when the remaining credit amount is sufficient to start the next game. For example, when a currently-selected bet is 50 whereas the remaining credit amount is 25, the spin prereading function is disabled. In the meanwhile, when a currently-selected bet is 50 whereas the remaining credit amount is 100, the spin prereading function is activated.
When the prereading is active, a corresponding button LED is turned on. When the prereading of the spinning is active, the spin button is illuminated.

Further, the horizontal axis K2 indicates a cumulative number of plays of the normal game a player or players has/have played. The right end of the horizontal axis is given a space to indicate the play of the normal game currently taking place, and 500 plays of the game are initially indicated on the horizontal axis. In other words, the last 500 plays of the game are indicated (the left end of the horizontal axis indicates the payout rate of a play which is 500 plays before the current play of the game).
For example, it is supposed that 15 credits are bet as the total bet amount to start the normal game, and a payout of 100 credits are awarded as the result of the normal game. In this case, the payout rate is 100/15≈6.7. After rounding off the decimal place, 1 is subtracted to result in 6. If the value of the payout rate in the previous play is plotted at the position of ×10, the payout rate of the current play is added: i.e., 10+6. Therefore, the current payout rate is plotted at the position of ×16. Then, the plot at the position of ×10 in the previous play and the plot of the payout rate of the current play at the position of ×16 are connected by a straight line. This way, the line-graph G1 is updated. The payout rate of the total win including the free game is indicated by a dotted line.
On the upper right of the graph screen display portion G11 is a graph information space K5. In the space, there is an indication that the black straight line in the graph indicates the payout rate related to the results of the normal game. Further, there is an indication that the dotted line in the graph indicates the payout rate related to the total win including the free game.
(Display Screen: Display of Scales in Line-Graph)
The upper and lower limit values of the vertical axis K1 shift according to the payout rate. Specifically, the points of the upper limit value and the lower limit value are shifted, as follows. Namely, with the points before the shift as the references, the points are shifted to values resulting from adding the value of the current payout rate to the points before the shift.
For example, as shown in
Further, when the payout rate of the current play is 0 or lower, the upper limit value and the lower limit value of the vertical axis K1 are shifted to the values resulting from subtracting 1 from each of the upper limit values and the lower limit values before the shift, respectively.
For example, as shown in

A box K35 under each column of the block-graph G3 indicates the number of plays of the normal game run from the last triggered free game or from the end of the last 15-choice pick game till the 15-choice pick game is newly triggered. It should be noted that the rightmost box K37 indicates the cumulative total of the plays of the normal game run from the last triggered free game or from the end of the last 15-choice pick game till the current time. The rightmost box K37, since it indicates the current value, is displayed in a different color from that of the other boxes K35 so as to make it noticeable to the player.

(Setting of Audit for Switching Graph Screen: Audit)
In the present embodiment, the line-graph G1, the bar-graph G2, and the block-graph G3 displayed on the graph screen display portion G11 are switchable to active or inactive state in Audit setting (see
With the above-described structure, when there is a payout, the main CPU 71 calculates the ratio of the payout relative to the amount of bet, and indicates it in the graph screen display portion G11. This enables the player to easily understand how much he/she won or lost.
Further, since the ratio of the total payout relative to the total amount bet is indicated for each unit game, the player is more easily understand how much he/she won or lost.
In cases where the normal game is played while repeating the unit game, changes in the payout rate is displayed in the form of a graph image in the graph screen display portion G11. This facilitates grasping of the tendency of the payout of the game.
Further, the change in the payout rate is shown as the line-graph G1 or the bar-graph G2 in the graph screen display portion G11. By switching the graph between the line-graph G1 and the bar-graph G2, the player is able to grasp the tendency of the payout of the game from different viewpoints.
Further, by looking at the start of the free game shown in the form of a mark image M311 in the graph image, the tendency in the payout after transition from the normal game to the free game is easily understood.
Further, different ways of indication in the line-graph G1 allows distinguishing the normal game (solid line) from the free game (dotted line). Therefore, the difference in the tendency of the payout between the normal game and the free game is easily understood.
Further, through the setting of AUDIT, one of or both the line-graph G1 and the bar-graph G2 are set to be enabled or disabled. This enables setting of displaying of graph images suitable for the type of game and the conditions under which the slot machine 1 is set up.
[Win Meter Information Display]
Now, win meter information display of the slot machine 1 will be described with reference to
As shown in
The win total amount display region 406 displays a win credit and a money amount. Increment display is performed based on a win increment speed sheet, when performed. More specifically, the win total amount display region 406A displays a credit amount obtained in the current game cycle (or in the previous game cycle). When a credit is obtained more than once in one game cycle, the credit is added each time it is obtained. For example, when the free game is triggered in the normal game and the player obtains a normal win 20 and a bonus win 100, the image display is incremented from “0” to “120”. Thereafter, when the player obtains a payout amount of 200 in the free game, the increment display is conducted from 120 to 320. 0 is displayed either when the next game cycle starts or when lost in GAMBLE. In the meanwhile, when a win is achieved in GAMBLE, no increment is carried out and the displayed amount is immediately doubled.
The detail display region 406 relates to a win in the normal game and the free game. After the 5th reel stops, the win credit is displayed. When more than one payout simultaneously occurs, the line payouts are displayed one by one at intervals of 0.5 second. The payouts are serially displayed in an ascending order of the payout amount, and the smallest payout is again displayed after the largest payout is displayed. In other words, the detail display region 406 displays the details of the credit obtained by the spinning in this time. When there are plural elements (e.g., another line or scatter), the elements are switched at intervals of 0.5 second.
The total display region 406C displays the total credits of the detail display region 406 when the increment in the win total amount display region 406A is completed. The region is not displayed until the increment in the win total amount display region 406A is completed. In other words, the detail display region 406C displays the details of the credit obtained by the spinning in this time. In this regard, the total credits are displayed after the increment in the win total amount display region 406A is finished.

(Overview of Invention of P14-0823)
The invention of P14-0823 relates to a gaming machine that yields a rescue award, when a game continues without awarding of any benefit.
Traditionally, in a facility where gaming machines such as slot machines and the like are set up, games are played by betting various types of gaming medium such as a credit and the like in the slot machines. In each slot machine are set a plurality of result determination areas (areas for which determination of winning or loss is carried out) on which a bet is placeable, and a benefit (payout) is awarded based on the number of result determination areas on which a bet is placed, the value of bet credit, and the game result.
Further, amongst the slot machines are those configured to perform an awarding (rescue) to the player, when the number of plays resulting no benefit reaches a predetermined number. For example, a constant amount of payout is awarded when the number of plays of the game resulting in no benefit reaches a predetermined value (so-called ceiling number).
It however may lead to unfairness if the rescue is conducted in the same manner, no matter the bets are placed only on a few result determination areas or on many result determination areas.
In view of the above, it is an object of the present invention to provide a gaming machine configured to yield a rescue award according to the number of result determination areas on which the player has placed a bet, when games without any benefit are continued.
An aspect of the present invention is a gaming machine, comprising: an input device that allows selection of any one or more result determination areas out of a plurality of result determination areas;
a display device configured to indicate a game result by rearranging a plurality of symbols in the one or more selected result determination areas;

store a threshold game count for a special game awarding a payout, for each of the plurality of winning areas, and
store a special game basic payout table determination table in which the plurality of winning areas are associated with a plurality of special game basic payout tables; and
a controller programmed to execute the processes of:
(1a) receiving a selection of the result determination areas through the input device,
(1b) incrementing the game count on the counter corresponding to the winning area selected in the step (1a), upon start of the game,
(1c) determining whether the game count on the counter has reached the threshold game count, and awards a special game trigger when the game count is determined as to have reached the threshold game count,
(1d) determining a special game basic payout table to be referred to in the special game, based on the winning area corresponding to the counter whose value has reached to the threshold game count in the step (1c) and the special game basic payout table determination table, and
(1e) when the special game is run, awarding a payout based on the special game basic payout table determined in the step (1d).
In the structure, the plurality of result determination areas are associated with the plurality of special game basic payout tables in the special game basic payout table determination table.
Therefore, it is possible to adjust an expectation value for the payout by the relation between each of the result determination areas to be selected by the player and the special game basic payout table to be the reference for the payout in the special game. As such, it is possible to set the expectation value for the payout of the special game according to the result determination areas selected by the player, and ensure the fairness of the payouts in the special game.
The above aspect of the present invention is adapted so that in the game, transition to the special game occurs when a predetermined condition is satisfied, and the controller is configured to perform the following steps of:
(1f) running the game, and when the predetermined condition is satisfied as the result of the game, determines the special game basic payout table to be referred to in the special game, based on the winning area selected in the step (1a) and the special game basic payout table determination table, and
(1g) when the predetermined condition is satisfied and transition to the special game occurs, awarding a payout based on the special game basic payout table determined in the step (1f).
With the structure, it is possible to use the special game basic payout table determination table as a table for determining the special game basic payout table used in the special game having been transited as the result of satisfying the predetermined condition in the game, and as a table for determining the special game basic payout table used in the special game transited when the game play count on the counter reaches the threshold game play count.
Further, another aspect of the present invention is a gaming machine, comprising: a result determination area input device that allows selection of any one or more result determination areas out of a plurality of result determination areas;
a display device configured to indicate a game result by rearranging a plurality of symbols in the one or more selected result determination areas;
a credit type input device that enables betting of any of a plurality of credit types of different credit values;
a storage unit configured to store a total counter that keeps track of the game count which is incremented upon start of the game, for each of the plurality of winning areas,
stores a credit type counter for each credit type, which keeps track of the game count incremented upon start of the game for each winning area,
store a threshold game count for the special game trigger of a special game awarding a payout, for each of the plurality of winning areas, and
store a plurality of payout rate random determination tables each of which is for determining the payout rate; and
a controller configured to award a benefit based on the credit bet and the combination of a plurality of symbols rearranged in the selected result determination area, and to execute the following processes of:
(2a) receiving a selection of the result determination areas through the result determination area input device and receiving a bet of any of the credit types through the credit type input device;
(2b) incrementing the game count on the total counter corresponding to the winning area selected in the step (2a), upon start of the game,
(2c) incrementing the game count on the credit type counter corresponding to the winning area selected in the step (2a) and to the credit type of the bet placed, upon start of the game,
(2d) determining whether the game count on the total counter has reached the threshold game count, and when the game count is determined as to have reached the threshold game count, calculating random determination probabilities, based on the percentage of the credit types in the threshold game count, and creates a payout rate random determination table determination table in which the calculated random determination probabilities are associated with the plurality of payout rate random determination tables;
(2e) executing a payout rate random determination table random determination for determining the payout rate random determination table, based on the payout rate random determination table determination table created in the step (2d);
(2f) executing payout rate random determination for determining the payout rate based on the payout rate random determination table determined in the step (2e); and
(2g) referring to the payout rate determined in the step (2f), at a time of awarding a payout in the special game.
With the above structure, the payout rate random determination table determination table is created according to the usage counts of each of the credit types at a time the value of the total counter reaches the threshold game play count. Then, based on the payout rate random determination table determination table created, the payout rate random determination table is determined, and random determination is executed for determining the payout rate in the special game based on the payout rate random determination having been determined. In this payout rate random determination, there is executed a random determination corresponding to the usage counts of each of the credit types at a time the game count reaches the threshold game count. That is, the usage count of each credit type at a time the value of the total counter reaches the threshold game play count affects determination of the payout rate in the special game. Therefore, each bet placed until the value of the total counter reaches the threshold game play count is not wasted, which ensures the fairness in the special game.

(1c) determining whether the game count on the counter has reached the threshold game count, and awards a special game trigger when the game count is determined as to have reached the threshold game count,
(1d) determining a special game basic payout table to be referred to in the special game, based on the winning area corresponding to the counter whose value has reached to the threshold game count in the step (1c) and the special game basic payout table determination table, and
(1e) when the special game is run, awarding a payout based on the special game basic payout table determined in the step (1d).
In the method, the plurality of result determination areas are associated with the plurality of special game basic payout tables in the special game basic payout table determination table. Therefore, it is possible to adjust an expectation value for the payout by the relation between each of the result determination areas to be selected by the player and the special game basic payout table to be the reference for the payout in the special game. As such, it is possible to set the expectation value for the payout of the special game according to the result determination areas selected by the player, and ensure the fairness of the payouts in the special game.
The above structures provide a gaming machine configured to yield a rescue award according to the number of result determination areas on which the player has placed a bet, when games without any benefit are continued.
(Overview of Invention of P14-0826)
The invention of P14-0826 relates to a gaming machine configured to display a game result by rearranging a plurality of types of symbols aligned on a plurality of video reels.
As an example of a gaming machine that awards a payout to the player according to a win of the game, there have traditionally been slot machines each of which having a plurality of reels having on their outer circumferential surfaces a plurality of symbols. In any of the above slot machines, a predetermined operation by the player starts a unit game, scroll reels displayed on a display so that a plurality of symbols on the outer circumferential surfaces of the reels are scroll displayed. Then, after elapse of a predetermined period, all the reels are stopped and the symbols on the reels are partially displayed on the display. Then, according to a combination of the displayed symbols, a payout is awarded, and the unit game is ended.
Among the above slot machines, there is a slot machine configured to disable scrolling of a predetermined symbol in a subsequent unit game, based on a predetermined condition, so that the predetermined symbol is kept displayed (fix-displayed) on the display. Since such a slot machine keeps displaying the predetermined symbol on the display, a combination of symbols containing that predetermined symbol is easily formed. This contributes to a higher expectation of the player for winning of a payout.
However, fixing the predetermined symbol in the subsequent unit game leads to exclusion of a symbol which was supposed to be stopped in the first place in the position where the predetermined symbol is fixed, in the subsequent unit game. That is, the player may miss a chance of winning a payout that could have been won if there was not the fixed symbol. This could lessen the player's expectation for winning of a payout.
In view of this, it is an object to provide a gaming machine in which a symbol to be rearranged in the first place in the position where the predetermined type of symbol is fixed is regarded as a symbol forming a combination of symbols subjected to awarding of a payout.
An aspect of the present invention is a gaming machine, comprising: a display device configured to display a game result by rearranging a plurality of types of symbols aligned on a plurality of video reels;
a storage unit configured to store a payout table in which a plurality of symbol combinations and a plurality of payouts are associated; and
a controller programmed to execute the processes of:
(1A) running a game and rearrange the plurality of symbols aligned on a plurality of video reels on the display device;
(1B) determining and awarding a payout, referring to a combination of the symbols rearranged on the display device and the payout table;
(1C) determining whether or not the symbols rearranged include a predetermined type of symbol, and if the symbols include the predetermined type of symbol, fixing the predetermined type of symbol on the display device until the game is run a predetermined number of times;
(1D) running the game again and rearrange the plurality of symbols aligned on the plurality of video reels on the display device;
(1E) determining and awarding a payout, referring to a combination of the symbols rearranged on the display device in the step (1D) and the symbol fixed in the step (1C), and the payout table;
(1F) if the symbol fixed in the step (1C) and a symbol rearranged in the step (1D) in the position of the symbol fixed in the step (1C) overlap with each other in the combination of symbols for which the payout is to be awarded as the result of the step (1E), a combination of symbols including the symbol fixed in the step (1C) and a combination of symbols including the symbol overlapped with the symbol fixed in the step (1C) are both subjected to awarding of a payout and are displayed.
(1G) repeating the step (1C) to (1F) until the predetermined number of plays of the game are consumed.
With the above structure, a predetermined type of symbol is accumulatively fixed, in the process of running a game a predetermined number of times. This facilitates formation of a combination including the predetermined type of symbol. Further, although the predetermined type of symbol is fixed, a symbol to be rearranged in the first place in the position where the predetermined type of symbol is fixed, as the result of rearranging a plurality of types of symbols aligned on the plurality of video reels, will be regarded as a symbol forming a combination of symbols subjected to awarding of a payout.
The gaming machine of the above aspect of the present invention is adapted so that:
the controller
in the step (1F), if a combination of symbols including the symbol fixed in the step (1C) is not a combination for which a payout is to be awarded and if a combination of symbols including a symbol to be rearranged in the step (1D) in the position of the symbol fixed in the step (1C) is a combination for which a payout is to be awarded, the controller displays the symbol to be rearranged in the step (1D) in the position of the symbol fixed in the step (1C) in front of the symbol fixed in the step (1C).
The above structure most preferentially displays on the display device a combination of symbols for which a payout is to be awarded.
The gaming machine of the above aspect of the present invention is adapted so that:
in the step (1F),
if a combination of symbols including the symbol fixed in the step (1F) is a combination for which a payout is to be awarded, and if a combination of symbols including a symbol to be rearranged in the step (1D) in the position of the symbol fixed in the step (1C) is a combination for which a payout is to be awarded,
the controller alternately displays on the display device the combination of symbols including the symbol fixed in the step (1C), and a combination of symbols including the symbol to be rearranged in the step (1D) in the position of the symbol fixed in the step (1C).
In the above structure, if a combination of symbols including the symbol fixed in the step (1F) is a combination for which a payout is to be awarded, and if a combination of symbols including a symbol to be rearranged in the step (1D) in the position of the symbol fixed in the step (1C) is a combination for which a payout is to be awarded, both of symbol combinations are displayed.
The gaming machine of the above aspect of the present invention is adapted so that in the step (1F), a symbol rearranged behind the symbol fixed is partially visible.
Traditionally, when a symbol is fixed, a symbol that is supposed to be stopped in the position of the fixed symbol will be excluded in the subsequent unit games. In this structure, the player may miss a chance of winning a payout that could have been won if there was not the fixed symbol. This could lessen the player's expectation for winning of a payout.
Further, if a symbol is fixed and a part of symbol rearranged behind the fixed symbol is visible, it could further disappoint the player.
Further, although the predetermined type of symbol is fixed, a symbol to be rearranged in the first place in the position where the predetermined type of symbol is fixed, as the result of rearranging a plurality of types of symbols aligned on the plurality of video reels, will be regarded as a symbol forming a combination of symbols subjected to awarding of a payout.
An aspect of the present invention is a method of controlling a gaming machine, comprising:
a display device configured to display a game result by rearranging a plurality of types of symbols aligned on a plurality of video reels;
a storage unit configured to store a payout table in which a plurality of symbol combinations and a plurality of payouts are associated; and
a controller,
the method comprising the controller-executed steps of:
(1A) running a game and rearrange the plurality of symbols aligned on a plurality of video reels on the display device;
(1B) determining and awarding a payout, referring to a combination of the symbols rearranged on the display device and the payout table;
(1C) determining whether or not the symbols rearranged include a predetermined type of symbol, and if the symbols include the predetermined type of symbol, fixing the predetermined type of symbol on the display device until a predetermined number of plays of the game are consumed;
(1D) running a game and rearrange the plurality of symbols aligned on a plurality of video reels on the display device;
(1E) determining and awarding a payout, referring to a combination of the symbols rearranged on the display device in the step (1D) and the symbol fixed in the step (1C), and the payout table;

Further, there is provided a gaming machine in which a symbol to be rearranged in the first place in the position where the predetermined type of symbol is fixed is regarded as a symbol forming a combination of symbols subjected to awarding of a payout.
(Overview of Invention of P14-0827)
The invention of P14-0827 relates to a gaming machine configured to display a game result by rearranging a plurality of types of symbols aligned on a plurality of video reels.
As an example of a gaming machine that awards a payout to the player according to a win of the game, there have traditionally been slot machines each of which having a plurality of reels having on their outer circumferential surfaces a plurality of symbols. In any of the above slot machines, a predetermined operation by the player starts a unit game, scroll reels displayed on a display so that a plurality of symbols on the outer circumferential surfaces of the reels are scroll displayed. Then, after elapse of a predetermined period, all the reels are stopped and the symbols on the reels are partially displayed on the display. Then, according to a combination of the displayed symbols, a payout is awarded, and the unit game is terminated.
Among the above slot machines, there is a slot machine configured to disable scrolling of a predetermined symbol in a subsequent unit game, based on a predetermined condition, so that the predetermined symbol is fixed (fix-displayed) on the display. Since such a slot machine keeps displaying the predetermined symbol on the display, a combination of symbols containing that predetermined symbol is easily formed. This contributes to a higher expectation of the player for winning of a payout.
However, in some cases, only fixing the predetermined symbol in the subsequent unit game may fall short for sufficiently satisfying the player's expectation for winning of a payout.
In view of the above, it is an object to provide a gaming machine configured to fix-display a predetermined symbol on the display and provide sufficient period for formation of a combination of symbols including the predetermined symbol, thereby enhancing the player's expectation for winning of a payout.
An aspect of the present invention is a gaming machine, comprising: a display device configured to display a game result of a normal game and a game result of a free game to which transition occurs from the normal game, by rearranging a plurality of types of symbols aligned on a plurality of video reels;
a storage unit configured to store a payout table in which a plurality of symbol combinations and a plurality of payouts are associated; and
a controller programmed to execute the processes of:
(1A) when the predetermined condition is satisfied as a result of the normal game, awarding a predetermined number of plays of a free game;
(1B) selecting any one or more symbols out of the plurality of types of symbols by means of random selection;
(1C) running the free game and rearrange the plurality of symbols aligned on a plurality of video reels on the display device;
(1D) determining and awarding a payout, referring to a combination of the symbols rearranged on the display device and the payout table;
(1E) determining whether or not the symbols rearranged include the one or more symbols selected in the step (1B), and if the symbols include the one or more symbols selected, fixing each of the one or more symbols selected on the display device until the game is run a predetermined number of times;
(1F) running the free game again and rearrange the plurality of symbols aligned on the plurality of video reels on the display device;
(1G) determining and awarding a payout, referring to a combination of the symbols rearranged on the display device in the step (1D) and the symbol fixed in the step (1E), and the payout table; and
(1H) repeating the steps (1E) to (1G) until the free game is run a predetermined number of times.
With the above structure, the one or more symbols randomly selected are accumulatively fixed, in the process of running a game a predetermined number of times. This facilitates formation of a combination including the one or more randomly selected symbols.
The gaming machine of the above aspect of the present invention may further comprise:
an input device that allows selection of any one or more result determination areas out of a plurality of result determination areas,
wherein the controller
executes a process of receiving a selection of a result determination area out of the result determination areas through the input device during the normal game,
in the step (1E), executes a process of determining whether or not the selected result determination area includes the one or more symbols selected in the step (1B), and if the selected result determination area includes the one or more symbols selected, fixing the one or more symbols selected in the selected result determination area until a predetermined number of plays of the free game are consumed; and
in the step (1G), executing a process of determining and awarding a payout, referring to a combination of the symbols including symbols rearranged in the selected result determination area and symbols fixed in the result determination area, and the payout table.
With the above structure, the one or more symbols randomly selected are accumulatively fixed only in the selected result determination area. This facilitates, according to the result determination area selected, formation of a combination including the one or more randomly selected symbols. Further, the one or more randomly selected symbols are not fixed in the non-selected result determination areas, which makes it possible to avoid giving an unnecessary expectation feeling to the player.
The gaming machine of the above aspect of the present invention may further comprise:
an additional bet device configured to enable placement of an additional bet which leads to awarding of a predetermined number of free games in addition to the foregoing predetermined number of free games, if a predetermined condition is satisfied as the result of the normal game.
wherein the controller
further executes a process of receiving an additional bet through the additional bet device during the normal game, and
executes in the step (1A) a process of awarding the predetermined number of free games in addition to the foregoing predetermined number of free games, if the predetermined condition is satisfied as the result of the normal game.
In the above structure, placing an additional bet by using the additional bet device may lead to an increase in the number of free games awarded when the predetermined condition is satisfied as the result of the normal game. With the above structure, the one or more symbols randomly selected are accumulatively fixed, in the process of running a game an increased number of times. This further facilitates formation of a combination including the one or more randomly selected symbols.
An aspect of the present invention is a method of controlling a gaming machine comprising: a display device configured to display a game result of a normal game and a game result of a free game to which transition occurs from the normal game, by rearranging a plurality of types of symbols aligned on a plurality of video reels;
a storage unit configured to store a payout table in which a plurality of symbol combinations and a plurality of payouts are associated; and
a controller,
