1. Field of the Invention
The present invention relates to a slot machine which includes a plurality of video reel strips.
2. Description of the Background Art
Conventionally, as a slot machine including a plurality of video reel strips, for example, there is a model which has the below-mentioned technology. In the technology which such a model has, since a game is subsequently initiated by the occurrence of triggering, the plurality of video reel strips are upgraded. When the plurality of video reel strips are upgraded, it becomes easy for a player to obtain a winning combination (for example, refer to US patent application publication 2012/0172106).
However, as a method of upgrading the plurality of video reel strips, for example, a method in which the number of wild symbols which can be substituted with any symbols is increased is adopted. Then, since it is easy for a player to recognize the increase in the number of the wild symbols, a player can soon perceive that the plurality of video reel strips have been upgraded.
Accordingly, a new design for upgrading the plurality of video reel strips has been desired by players.
Therefore, in view of the above-described respect, the present invention was made. An object of the present invention is to provide a slot machine which realizes a new design for upgrading the plurality of video reel strips.
In addition, there also is a slot machine equipped with a jackpot function. The jackpot function serves such that each predetermined money amount is accumulated each time betting is conducted and when a jackpot is won, a money amount based on the money amounts accumulated until then is paid out to a player. In the conventional slot machine, money amounts to be accumulated can be determined in accordance with the number of bets placed when betting is conducted, and when the number of bets placed is large, the accumulated money amounts is large whereas the number of bets placed is small, the accumulated money amounts is small.
Therefore, a player who expects winning of a jackpot increases the number of BETs and proceeds with a game. Accordingly, while such a player is playing the game, upon the occurrence of the winning of the jackpot, a benefit in accordance with the investment made by the player can be provided.
However, while such a player is playing the game, without the occurrence of the jackpot, any benefit cannot be provided despite the investment made by the player. Furthermore, another player starting a game thereafter may to be provided with a benefit awarded by the jackpot. Therefore, unfairness results between a player who has made an investment and a player who has not made an investment. This leads to an increase in the number of players who each decreases the number of BETs placed to proceed with a game, and as a result, the consumption of coins is decreased, resulting in a likelihood of a decrease in a profit of a shop such as a casino.
Given this situation, a slot machine which can reduce the unfairness among players and allows a player to proceed with a game in expectation of a jackpot has been desired.
According to the present invention made to solve the above-mentioned problem, provided is a slot machine in which in a feature game including a set of a plurality of free games shifted from a base game, a screen on which a plurality of kinds of character symbols composed of images of, for example, heads of particular animals or the like to be selected are set face down is displayed; a selection of one kind from the plurality of kinds of character symbols is made by using a selection device such as the later-described touch panel; and a processor performs control such that video reel strips which are changed so as to have character symbols of the one kind selected from the plurality of kinds of character symbols are used, a number of the symbols of the selected one kind being larger than a number of symbols of the selected one kind used in the base game.
In the present specification, the later-described bonus game and the feature game are used in the same meaning.
When the number of character symbols of the one kind selected by using the selection device is increased, the number of symbols of each of the plurality of kinds of symbols including the character symbols displayed on one video reel strip may be made constant by decreasing the numbers of character symbols of the kinds other than the one kind.
In other words, when the processor performs control such that in the feature game shifted from the base game, each of the video reel strips, on which the number of the character symbols corresponding to the character symbols of the one kind selected by using the selection device is increased, is changed so as to have the increased number of character symbols of the selected one kind. Since each of the video reel strips is changed so as to have the same number of symbols by decreasing the number of the other symbols which corresponds to the increased number of the character symbols, it is likely to easily make a design which allows a control program of the processor in the feature game to serve a double purpose.
The invention according to claim 1 is a slot machine including: a selection device operated by a player; a first display for displaying a part of a plurality of video reel strips having different kinds of symbols arranged thereon, the symbols including a plurality of kinds of character symbols; and a processor for causing a slot game including a base game and free games to proceed on the first display, the processor being programmed to execute processes (A) to (C) described below.
(A) A process in which upon causing the base game to proceed, used are base game reel strips on which on all of the plurality of video reel strips, symbols whose each kind is the same are arranged in succession.
(B) A process in which immediately after shifting from the base game to the free games, a selection game in which a player selects one kind of character symbols from the plurality of kinds of character symbols by using the selection device is caused to proceed.
(C) A process in which upon causing the free games to proceed, used are free game reel strips on which on all of the plurality of video reel strips, the symbols whose each kind is the same are arranged in succession and only in a case of the one kind of character symbols selected in the selection game, symbols of the selected one kind are arranged in succession, a number of the symbols of the selected one kind being larger than a number of symbols of the selected one kind displayed on the base game reel strips.
The slot machine according to claim 1 has the above-described configuration, thereby causing the slot game including the base game and the free games to proceed on the display. While the base game is proceeding, the base game video reel strips are used. On the base game video reel strips, on all of the plurality of video reel strips, the symbols whose each kind is the same are arranged in succession. Immediately after shifting from the base game to the free games, the selection game in which a player selects the one kind of character symbols from the plurality of kinds of character symbols by using the selection device is caused to proceed. While each of the free games is proceeding, the free game video reel strips are used. On the free game video reel strips, on all of the plurality of video reel strips, the symbols whose each kind is the same are arranged in succession and only in the case of the one kind of character symbols selected in the selection game, the symbols of the selected one kind are arranged in succession, the number of the symbols of the selected one kind being larger than the number of symbols of the selected one kind displayed on the base game reel strips.
In other words, on the base game reel strips and the free game reel strips, the mode in which on all of the plurality of video reel strips, the symbols whose each kind is the same are arranged in succession is common to each other. In addition, by the mode in which on the free game video reel strips, only in the case of the character symbols of the one kind selected in the selection game which proceeds immediately after shifting from the base game to the free games, the symbols of the selected one kind are arranged in succession, the number of the symbols of the selected one kind being larger than the number of symbols of the selected one kind displayed on the base game reel strips, the plurality of video reel strips are upgraded.
In addition, the invention according to claim 2 is the slot machine according to claim 1 includes a second display for displaying free game payout tables during progress of the free games, the plurality of kinds of character symbols having the free game payout tables which are different from one another, the processor being programmed to execute a processes (D) described below.
(D) A process in which during the progress of the free games, a background image related to the one kind of character symbols selected in the selection game is displayed on the first display and the second display.
The slot machine according to claim 2 has the above-described configuration, whereby while each of the free games is proceeding, the free game payout tables of the plurality of character symbols, which are respectively different from one another, are displayed on the second display and the background image related to the one kind of character symbols selected in the selection game is displayed on the first display and the second display.
In other words, on the second display on which while each of the free games is proceeding, the free game payout tables of the plurality of character symbols, which are respectively different from one another, are displayed, the background image related to the one kind of character symbols selected in the selection game is displayed. Further, on the first display, while each of free games is proceeding by using the free game video reel strips having the mode in which only in the case of the one kind of character symbols selected in the selection game, the symbols of the selected one kind are arranged in succession, the number of the symbols of the selected one kind being larger than the number of symbols of the selected one kind displayed on the base game reel strips, the background image related to the one kind of character symbols selected in the selection game is displayed.
Accordingly, the background image related to the character symbols used upon upgrading the plurality of video reel strips is displayed on the first display and the second display during the progress of the free games.
Further, the invention according to claim 3 has a payout table in which payouts provided in accordance with winning when in the free games executed after the process (C), the character symbols of the one kind selected in the selection game are displayed on the first display and winning is determined are respectively different from one another depending on the plurality of kinds of character symbols.
By employing this configuration, brought about are a case where the video reel strips are changed such that on the video reel strips, character symbols whose payout is the largest, as compared with a payout of the character symbols of any one selected by a player from the plurality of kinds of character symbols by using the selection device, are displayed; and a case where the video reel strips are changed such that on the video reel strips, character symbols whose payout is the lowest, as compared with a payout of the character symbols of any one selected by a player from the plurality of kinds of character symbols by using the selection device, are displayed, thereby allowing the free games to have a variety of game elements.
In this case, the memory has stored therein data including: weighting data for determining a probability with which character symbols, whose payout is large, associated with video reel strips on which a number of character symbols with a large payout is increased, appear on the first display: and weighting data for determining a probability with which character symbols, whose payout is small, associated with video reel strips on which a number of character symbols with a small payout is increased, appear on the first display, which are different from each other, thereby allowing the weighting data to be changed in accordance with selected character symbols. By employing the above-described configuration in which the weighting data is changed in accordance with each of the plurality of kinds of character symbols with the large payouts and the small payouts, a likelihood with which the character symbols with the large payout, as compared with the character symbols with the small payout, are displayed on the first display and winning is determined is set to be low, whereby it is likely to easily make a design which avoids a likelihood with which a payout percentage may largely vary depending on a selected kind of character symbols.
In other words, in the invention according to claim 4, the processor sets data to perform control such that in the free games, a probability with which winning determined when character symbols, whose payout is large, among the plurality of kinds of character symbols are displayed on the first display occurs is lower than a probability with which winning determined when character symbols, whose payout is small, among the plurality of kinds of character symbols are displayed on the first display occurs.
In addition, in the invention according to claim 5, the processor is configured to perform control such that in the process (C), all of the free game video reel strips associated with each of the plurality of kinds of character symbols have the same total numbers of symbols by decreasing a number of the other symbols by an increased number of each of the plurality of the kinds of the character symbols, the decreased number of the other symbols being the same as the increased number of each of the plurality of the kinds of the character symbols.
Further, the present embodiment is characterized in that the processor is programmed to execute processes (E) and (F) described below.
(E) A process in which each money amount which is constant is accumulated independently of a number of bets each time betting is conducted.
(F) A process in which upon winning a jackpot, a money amount calculated by multiplying a money amount accumulated until then by a multiplying factor based on the number of bets is provided.
Since each constant money amount can be accumulated independently of the number of bets, a player can proceed with a game at ease without worrying about providing of a benefit awarded by a jackpot for other players.
In addition, the present embodiment includes: an operation device operated by a player; a display for displaying a plurality of video reels having a plurality of symbols arranged thereon, the plurality of symbols including a plurality of kinds of character symbols; and a processor for causing a slot game to proceed by rearranging the symbols on the display, the processor being programmed to execute processes (A-1) and (A-2) described below.
(A-1) A process in which each money amount which is constant is accumulated independently of a number of bets by using the operation device each time a predetermined number of bets is placed.
(A-2) A process in which upon winning a jackpot, a money amount based on a money amount calculated by multiplying a money amount accumulated until then by a multiplying factor based on the number of bets is provided.
Since the each constant money amount can be accumulated independently of the number of bets, a player can proceed with a game at ease without worrying about providing of a benefit awarded by a jackpot for other players.
Further, the present embodiment is characterized in that the (A-1) process includes processes (A-1-1) and (A-1-2) described below.
(A-1-1) A process in which when a predetermined number of bets is placed by using the operation device, a money amount is calculated as an accumulated money amount by dividing a bet money amount by the number of bets.
(A-1-2) A process in which each of the accumulated money amounts is stored so as to correspond to each of the plurality of character symbols, respectively.
Each constant money amount can be appropriately accumulated, thereby allowing a benefit awarded by a jackpot to be appropriately provided for a player.

As characters of the character symbols, there are animals and human figures.
In the present specification, the feature game and the bonus game are the same in meaning. In general, in some countries and manufactures, the feature game is referred to as the bonus game or vice versa.
Hence, according to the present invention, provided is a slot machine which realizes a new design for upgrading a plurality of video reel strips.
Hereinafter, a first embodiment will be described with reference to the accompanying drawings.
The slot game is of a line-type. On a first display (lower side image display panel), 50 paylines are set on a screen having a configuration consisting of 4 columns×5 rows. Further, in the slot game, video reels are used. The video reels are composed of five reels. In other words, a first reel, a second reel, a third reel, a fourth reel, and a fifth reel constitute the video reels.
Feature symbols are present on the second reel, the third reel, and the fourth reel. Wild symbols are present on the second reel, the third reel, the fourth reel, and the fifth reel. A plurality of animal symbols and the other symbols are present on all of the reels. The wild symbols, the plurality of animal symbols, and the other symbols are respectively arranged in succession. The plurality of animal symbols are symbols of lions (LION), tigers (TIGER), black leopards (BLEOPARD), white leopards (WLEOPARD), and cheetahs (CHEETAH) as described below.
During the base game, base game reel strips are used on the respective video reels. During the free games, free game reel strips are used on the respective video reels. On the free game video reel strips, only in a case of one kind of animal symbols, selected in a selection game proceeding immediately after the game is shifted from the base game to the free games, the selected kind of animal symbols whose number is further larger than the number of the selected kind of animal symbols arranged in the base game are arranged in succession. In other words, there are five kinds of the free game video reel strips, and only in the case of one kind of animal symbols selected in the selection game, each of the five kinds of the free game video strips, on which the larger number of the selected kind of animal symbols are arranged in succession is used in the free games.
In the base game, when three feature symbols have appeared (step S1), eight free games can be obtained. At this time, a free game payout table in which payouts for the five kinds of animal symbols are different from one another is displayed on a second display (upper side image display panel).
Immediately after shifting to the free games, one kind is selected by a player from the five kinds of animal symbols via a button or a touch panel (step S2). It is determined that only in a case of the selected one kind of animal symbols, the free game video reel strips on which the larger number of the selected one kind of animal symbols than in the base game are arranged in succession are used (step S3). At this time, a background image related to the one kind of animal symbols selected in the selection game is displayed on the first display (lower side image display panel) and the second display (upper side image display panel).
During the free games, after spinning (step S4), when three feature symbols have appeared again (step S5: YES), retriggering is conducted. Upon the occurrence of the retriggering, eight free games are added (step S6). Thereafter, the game returns to the above-mentioned step S4 and the spinning is conducted again. Accordingly, in the retriggering, newly selecting another one kind from the five kinds of animal symbols is not conducted. In other words, the free game video reel strips determined immediately after shifting to the free games are used until said free games are finished. Further, the number of times at which the retriggering is conducted has no limit. Accordingly, each time the retriggering occurs, eight free games are added (step S6).
In contrast to this, when the three feature symbols have not appeared again (step S5: NO), it is determined whether or not the remaining number of times at which the free game is conducted is zero (step 7). When the remaining number of times at which the free game is conducted is not zero (step S7: NO), the game returns to the above-mentioned step S4 and the free games are continued. On the other hand, when the remaining number of times at which the free game is conducted is zero (step S7: YES), the game returns to the base game.
The flow shown in
The slot machine has the above-described configuration, thereby causing the slot game including the base game and the free games to proceed on the first display (lower side image display panel). While the base game is proceeding, the base game reel strips are used. On the base game reel strips, on all of the five reels, symbols whose each kind is the same, other than the feature symbols, are arranged in succession, the symbols including the animal symbols of the five kinds and the kinds of the symbols being different from one another.
Immediately after shifting from the base game to the free games, the selection game in which a player selects one kind from the five kinds of animal symbols via the button or the touch panel proceeds (step S2).
While each of the free games is proceeding, the free game reel strips are used. On the free game reel strips, on all of the five reels, symbols whose each kind is the same, other than the feature symbols, are arranged in succession and in addition thereto, only in the case of the one kind of animal symbols selected in the selection game, the larger number of the animal symbols of the selected one kind are arranged in succession than on the base game video reel strips.
In other words, in the base game reel strips and the free game reel strips, the mode in which on all of the five reels, symbols whose each kind is the same, other than the feature symbols, are arranged in succession is common to each other. In addition, by the mode in which on the free game reel strips, only in the case of the one kind of animal symbols selected in the selection game, the larger number of the animal symbols of the selected kind are arranged in succession than on the base game video reel strips, the five video reel strips are upgraded.
Further, the slot machine has the above-described configuration, thereby displaying the free game payout table, in which the payouts for the five kinds of animal symbols are different from one another, on the second display (upper side image display panel) while each of the free games is proceeding and thereby displaying the background image related to the one kind of animal symbols selected in the selection game on the first display (lower side image display panel) and the second display (upper side image display panel).
In other words, the free game payout table, in which the payouts for the five kinds of animal symbols vary respectively, is displayed on the second display (upper side image display panel) displayed while each of the free games is proceeding, and the background image related to the one kind of animal symbols selected in the selection game is displayed. Further, on the first display (lower side image display panel), the background image related to the one kind of animal symbols selected in the selection game is displayed during the progress of free games in which used are the free game video reel strips in the mode in which only in the case of the one kind of animal symbols selected in the selection game, the larger number of the animal symbols of the selected one kind are arranged in succession than on the base game video reel strips.
Accordingly, the background image related to the animal symbols used upon upgrading the five video reel strips is displayed on the first display (lower side image display panel) and the second display (upper side image display panel) during the progress of the free games.
[Explanation of a Function Flow]
With reference to
<Coin-in/Start-Check>
First, the slot machine checks whether or not any BET button is pressed by a player and subsequently checks whether or not a SPIN button is pressed by a player.
<Determination of Symbols>
Next, when the SPIN button is pressed by a player, the slot machine extracts random number values for determining symbols and determines symbols to be displayed to a player upon stopping of scrolling of symbol columns in accordance with the plurality of video reels displayed on the display.
<Display of Symbols>
Next, the slot machine starts the scrolling of the symbol columns of the respective video reels and stops the scrolling so as to display the determined symbols to a player.
<Winning Determination>
Next, upon stopping the scrolling of the symbol columns of the respective video reels, the slot machine determines whether or not a combination of the symbols displayed to a player is associated with a winning combination.
<Paying-Out>
Next, when the combination of the symbols displayed to a player is the winning combination, the slot machine awards a benefit in accordance with a kind of the combination of these symbols to a player. For example, when a combination of symbols related to a payout of coins is displayed, the slot machine pays out, to a player, coins whose number is in accordance with the combination of the symbols.
In addition, when a combination of symbols related to triggering of a bonus game is displayed, the slot machine initiates the bonus game. In the first embodiment of the present invention, as the bonus game, a game (free games) in which a drawing for determining the above-mentioned symbols to be stopped is conducted without consuming coins at a predetermined number of times is conducted.
In addition, when a combination of symbols related to triggering of a jackpot is displayed, the slot machine pays out coins corresponding to a jackpot amount to a player. The jackpot functions such that portions of coins consumed by a player on respective slot machines are accumulated as jackpot amounts and, when the triggering of a jackpot has been achieved on any slot machine, coins corresponding to the accumulated jackpot amounts are paid out to such a slot machine. The slot machine calculates an amount to be accumulated as the jackpot amount each time one game is played (cumulative amount) and transmits the calculated amount to an external control apparatus. The external control apparatus accumulates cumulative amounts transmitted from the respective slot machines as the jackpot amounts.
In addition, in the slot machine, besides the above-mentioned benefit, benefits such as a mystery bonus and insurance are provided. The mystery bonus is to pay out coins corresponding to a predetermined amount upon the occurrence of winning in a dedicated drawing. When the SPIN button is pressed, the slot machine extracts random number values for the mystery bonus and determines, through the drawing, whether or not the triggering of the mystery bonus is to be achieved.
The insurance is a function provided for the purpose of helping a player who is in the situation where any bonus game is not conducted for a long period of time. In the first embodiment of the present invention, whether or not the insurance is made active can be arbitrarily selected by a player. In exchange for a predetermined insurance purchase amount, the insurance is made active. When the insurance is made active, the slot machine starts counting of the number of times of games played. When without a large amount being paid out by the bonus game and the like, the counted number of times of the games played reaches a predetermined number of times, the slot machine pays out coins corresponding to an amount which has been set for the insurance.
<Determination of Presentation Effects>
The slot machine performs presentation effects through displaying of images using the display, outputting of light using a lamp, and outputting of sound using a loudspeaker. The slot machine extracts random number values for the presentation effects and based on symbols, determined through a drawing, and the like, determines contents of the presentation effects.

The noteworthy respect is that previously stored is reel strip data which sets a total number of symbols N on the video reel strips, including an increased number of symbols of any one kind among the plurality of kinds of character symbols of lions, tigers, black leopards, white leopards, and cheetahs so as to be the same number invariably even when symbols of any one kind of the plurality of kinds of character symbols are increased. In other words, in the present invention, the processor is configured such that in the process of setting the video reel strips in the free games executed by the processor, on the free game video reel strips associated with each of the plurality of kinds of character symbols, the increased number of the character symbols of any one of the plurality of kinds of character symbols is offset by reducing the numbers of the other symbols and all of the free game video reel strips have the same total number of symbols.
In addition, in the free game payout table, payouts awarded in accordance with respective winning combinations when any of the character symbols (lions, tiger, black leopards, white leopards, and cheetahs) selected in the selection game are displayed on the first display (lower side image display panel) and it is thereby determined that winning has occurred are different from one another depending on the plurality of kinds of character symbols. However, of course, the free game payout table may be configured such that all the payouts are the same as one another.
Further, when the free game payout table is configured such that the payouts are different from one another depending on the kinds of the character symbols, if a probability for the winning which involves character symbols with large payout is equal to a probability for winning which involves character symbols with small payout, then total payout amounts in the feature game are likely to be largely different from one another depending on a result of the selection.
In order to avoid the above-described situation, the processor sets data to perform control such that in the free games, a probability for the winning which involves character symbols with large payout is lower than a probability for winning which involves character symbols with small payout. A nonvolatile memory of a memory card 54 has the above-described data stored therein, also thereby allowing setting of weighting of the kinds of character symbols to be displayed on the first display.
Data for changing the above-mentioned weighting is previously prepared, and it is also made possible for the processor to perform control such that the total payout amount per one feature game does not largely change depending on the selected kind of character symbol.

[Configuration of Circuitry Included in Slot Machine]
The configuration of the symbol columns which the video reels 3 of the slot machine 1 have is as described above. Next, with reference to
A gaming board 50 includes: a CPU 51, a ROM 52, and a boot ROM 53, which are connected to one another by an internal bus; a card slot 55 associated with a memory card 54; and an IC socket 57 associated with a GAL (Generic Array Logic) 56.
The memory card 54 is composed of a nonvolatile memory and has a game program and a game system program stored thereon. The game program includes a program related to game proceeding, a drawing program, and a program for executing presentation effects by images and sounds (for example, refer to
The drawing program is to determine symbols on the respective video reels 3, which are scheduled to be stopped, by a drawing. The data pertinent to the symbols scheduled to be stopped is data for determining four symbols displayed in the symbol display area 4 from the plurality of symbols constituting each of the symbol columns. The slot machine 1 according to the first embodiment of the present invention determines symbols displayed in predetermined areas (for example, the areas in the upper row) among the four areas associated with each of the video reels 3 as the symbols scheduled to be stopped.
The above-mentioned drawing program includes symbol determination data. The symbol determination data is to define random number values in accordance with each of the video reels 3 such that each of the plurality of symbols constituting each of the symbol columns is determined with an equal probability. For example, in a case of the first video reel (“Reel 1”) 3a of the base game video reel strips, by using the symbol determination data, random number values are determined such that each of the 84 symbols (code Nos. “00” to “83”) is determined with the equal probability (specifically, 1/84). However, since the numbers of the respective kinds of the symbols included in the 84 symbols are different, probabilities with which the respective kinds of the symbols are determined are different from one another (in other words, weights are yielded). For example, with reference to
In the first embodiment of the present invention, the data is defined such that the numbers of the kinds of the symbols constituting the respective symbol columns are different from one another in accordance with each of the video reels 3. However, the numbers of the kinds of the symbols constituting the respective symbol columns may be the same as one another. For example, each of all of the symbol columns of the video reels 3a to 3e of the base game video reel strips and the free game video reel strips may be configured so as to be formed of 22 symbols. Thus, a degree of freedom upon setting probabilities with which the respective kinds of symbols are determined in accordance with each of the video reels 3 is increased.
In addition, the card slot 55 is configured such that the memory card 54 can be inserted thereto and pulled out therefrom and is connected to a mother board 70 by an IDE bus.
The GAL 56 is a kind of a PLD (Programmable Logic Device) having a fixed OR array architecture. The GAL 56 includes a plurality of input ports and output ports and when each of the input ports has received a predetermined input, corresponding data is outputted from each of the output ports.
In addition, the IC socket 57 is configured such that the GAL 56 is detachable and is connected to the mother board 70 by a PCI bus. The memory card 54 is replaced with a memory card having another program written thereon or the program written on the memory card 54 is replaced with another program, thereby allowing the contents of a game played on each of the slot machines 1 to be changed.
The CPU 51, the ROM 52, and the boot ROM 53 connected to one another by the internal bus are connected to the mother board 70 by the PCI bus. The PCI bus transmits signals between the mother board 70 and the gaming board 50 and supplies power from the mother board 70 to the gaming board 50.
The ROM 52 has an authentication program stored thereon. The boot ROM 53 has stored thereon an auxiliary authentication program, a program (boot code) for allowing the CPU 51 to activate the auxiliary authentication program, and the like. The authentication program is a program (tampering check program) for authenticating the game program and the game system program. The auxiliary authentication program is a program for authenticating the above-mentioned authentication program. The authentication program and the auxiliary authentication program are written along a procedure (authentication procedure) for authenticating that a targeted program is not tampered.
The mother board 70 includes: a main CPU 71, a ROM 72, a RAM 73, and a communication interface 82.
The ROM 72 is composed of a memory device such as a flash memory and has stored thereon a program such as a BIOS (Basic Input/Output System) executed by the main CPU 71 and permanent data. When the BIOS is executed by the main CPU 71, an initialization process for predetermined peripheral devices is conducted. In addition, via the gaming board 50, a process for loading the game program and the game system program stored on the memory card 54 is started.
The processor in the present invention includes the above-mentioned main CPU 71, ROM 72, RAM 73, and the memory card 54 having stored thereon the game program and the game system program, and the CPU 71 executes the game program and the game system program, thereby controlling the slot machine. Needless to say, the configuration of said processor is not limited thereto, and a configuration in which instead of the memory card 54, the ROM 72 has stored thereon the game program and the game system program may be adopted.
The RAM 73 has stored thereon data and programs used when the main CPU 71 operates. For example, when the process for loading the above-described game program and game system program and the authentication program is conducted, these can be stored thereon. In addition, the RAM 73 is provided with working areas for executing each of the above-mentioned programs. For example, provided are an area for storing the number of games, the number of BETs, the number of payouts, the number of credits, and the like and an area for storing symbols (code Nos.) determined by a drawing.
A communication interface 82 is to communicate with the external control apparatus 200 such as a server via the communication line 301. In addition, connected to the mother board 70 by USBs are the later-described door PCB (Printed Circuit Board) 90 and main body PCB 110. Further, connected to the mother board 70 is a power source unit 81. When power is supplied from the power source unit 81 to the mother board 70, the main CPU 71 of the mother board 70 is activated and the power is supplied to the gaming board 50 via the PCI bus, thereby activating the CPU 51.
Connected to the door PCB 90 and the main body PCB 110 are input devices such as switches and sensors; and peripheral devices whose operations are controlled by the main CPU 71. Connected to the door PCB 90 are a control panel 30, a reverter 91, a coin counter 92C, and a cold-cathode tube 93.
The control panel 30 is provided with a SPIN switch 31S, a CHANGE switch 32S, a CASHOUT switch 33S, a 1-BET switch 34S, and a MAX BET switch 35S so as to correspond to the above-described respective buttons. Each of the switches detects that each of the corresponding buttons is pressed by a player and outputs a signal to the main CPU 71.
A coin counter 92C makes a selection to determine whether or not a material, a shape, and the like of each of the coins inputted into the coin receiving slot 36 are appropriate. Upon detecting each appropriate coin, the coin counter 92C outputs a signal to the main CPU 71. In addition, inappropriate coins are discharged from a coin payout opening 15A.
The reverter 91 operates based on a control signal outputted from the main CPU 71 and distributes the appropriate coins selected by the coin counter 92C to a hopper 113 or a cashbox (not shown). When the hopper 113 is not filled with the coins, the appropriate coins are distributed to the hopper 113 and when the hopper 113 is filled with the coins, the appropriate coins are distributed to the cashbox.
A cold-cathode tube 93 functions as a backlight installed on a side of back surfaces of the upper side image display panel 131 and the lower side image display panel 141 and lights up based on a control signal outputted from the main CPU 71.

The lamp 111 lights up based on a control signal outputted from the main CPU 71. The loudspeaker 112 outputs sound such as BGM based on a control signal outputted from the main CPU 71.
The hopper 113 operates based on a control signal outputted from the main CPU 71 and pays out coins, whose payout number is designated, from the coin payout opening 15A to the coin tray 15. The coin detection part 113S detects the coins provided by the hopper 113 and outputs a signal to the main CPU 71.
The touch panel 114 detects a position touched by a finger or the like of a player on the lower side image display panel and outputs a signal corresponding to the detected position to the main CPU 71. The bill validator 115, upon accepting each legitimate bill, outputs a signal in accordance with an amount of the accepted bill to the main CPU 71.
The graphic board 130 controls a display of images, performed by each of the upper side image display panel 131 and the lower image display panel 141, based on a control signal outputted from the main CPU 71. In the symbol display area 4 of the lower side image display panel 141, the five video reels 3 are displayed, and motions of the scrolling and the stoppage of the symbol columns which the respective video reels 3 have are displayed. The graphic board 130 includes a VDP for generating image data, a video RAM for storing the image data generated by the VDP, and the like.
In addition, the graphic board 130 includes the VDP (Video Display Processor) for generating image data based on a control signal outputted from the main CPU 71, the video RAM for temporarily storing the image data generated by the VDP, and the like. The image data used when the image data is generated by the VDP is included in the game program read out from the memory card 54 and stored in the RAM 73.
The ticket printer 171 prints onto a ticket a bar code, in which data such as the number of credits stored on the RAM 73, time and date, and an identification number of a slot machine 1 is coded, based on a control signal outputted from the main CPU 71 and outputs the ticket as a ticket having a bar code 175.
The card reader 172 reads out data stored on a card inserted into the card slot 176, transmits the data to the main CPU 71, and writes the data based on a control signal from the main CPU 71.
The key switch 173S is provided on the keypad 173 and, when the keypad 173 is operated by a player, outputs a predetermined signal to the main CPU 71.
The data indicator 174 displays the data read out by the card reader 172 and the data inputted by a player via the keypad 173, based on a control signal outputted from the main CPU 71.
[Configuration of Symbol Combination Table]
The configuration of the circuitry of the slot machine 1 is as described above. Next, with reference to
The symbol combination tables define symbol combinations and the numbers of payouts associated with winning. On the slot machine 1, when the scrolling of the symbol columns of the respective video reels 3 is stopped and a combination of symbols displayed on a payline matches any combination of symbols defined in the symbol combination tables, winning occurs. In accordance with the winning, a player is provided with a benefit such as a payout of coins and initiation of a bonus game. When a combination of symbols displayed on a payline does not match any of the combinations of symbols defined in the symbol combination tables, no winning occurs (that is, losing occurs).
Basically, with respect to the respective kinds of the symbols “LION”, “TIGER”, “BLEOPARD”, WLEOPARD”, “CHEETAH”, “ACE”, “KING”, “QUEEN”, “JACK”, “TEN”, and “NINE”, also when three, four, or five symbols of one kind among the above-mentioned kinds are displayed on a payline by the video reels 3, winning occurs. In addition, with respect to the kinds of the symbols “LION”, “TIGER”, “BLEOPARD”, WLEOPARD”, and “CHEETAH”, two symbols of one kind among the above-mentioned kinds are displayed on a payline by the video reels 3, winning occurs. These wins are associated with LINE payouts, resulting in multiplication of BET PER LINE. The symbols of the kinds of “LION”, “TIGER”, “BLEOPARD”, WLEOPARD”, “CHEETAH”, “ACE”, “KING”, “QUEEN”, “JACK”, “TEN”, and “NINE” are substituted for the wild symbols.
For example, when in the base game and the free games, the symbols “LION” are displayed together on a payline by all of the video reels 3, “100” is determined as the number of a payout. This win is associated with a LINE payout, and a value of BET PER LINE is multiplied by this “100”. Coins whose number is based on the result of the multiplication are paid out. The paying-out of the coins is conducted by actually discharging the coins from the coin payout opening 15A, by adding a value of the result of the multiplication to the number of credits, or by issuing a bar code ticket.
The symbols “LION”, “TIGER”, “BLEOPARD”, WLEOPARD”, and “CHEETAH” are the animal symbols of lions, tigers, black leopards, white leopards, and cheetahs as described above.
The symbols “FEATURE” are symbols related to the triggering of a bonus game. When three symbols “FEATURE” are displayed by the second video reel (“Reel 2”) 3b, the third video reel (“Reel 3”) 3c, and the fourth video reel (“Reel 4”) 3d, “2” is determined as the number of a payout of a scatter pay. A value of TOTAL BET is multiplied by a value of this SCATTER payout. Starting from the next game, the bonus game (free games) is initiated. Also when a total of the number of the displayed symbols “FEATURE” and the number of the displayed symbols “WILD” is a predetermined number (for example, 3), “2” is determined as the number of a payout of the scatter pay. Starting from the next game, the bonus game (free games) is initiated. However, when the three symbols “FEATURE” are displayed, this winning is not that of the LINE payout for which a value of BET PER LINE is multiplied by the number of a payout. No winning of the LINE payout occurs in association with the symbols “FEATURE”. In addition, no winning of the LINE payout occurs by replacing the symbols “WILD” with the symbols “FEATURE”.
When a predetermined combination composed of symbols of any of the kinds of symbols “LION”, “TIGER”, “BLEOPARD”, WLEOPARD”, and “CHEETAH”, “ACE”, “KING”, “QUEEN”, “JACK”, “TEN”, and “NINE” is displayed on a payline, a jackpot trigger occurs and a jackpot amount is determined as the number of a payout.
[Contents of Programs]
The symbol combination tables are as described above. Next, with reference to
<Main Control Processes>
First, with reference to
First, when the slot machine 1 is powered on, the main CPU 71 reads out an authenticated game program and an authenticated game system program from the memory card 54 via the gaming board 50 and writes the programs into the RAM 73 (step S11).
Next, the main CPU 71 conducts a one-game-termination-time initialization process (step S12). For example, data such as symbols determined by the number of BETs and a drawing, which becomes unnecessary in a work area of the RAM 73 upon the termination of each one game played, is cleared.
Next, the main CPU 71 conducts a coin-in/start-check process described later with reference to
Next, the main CPU 71 conducts a symbol drawing process described later with reference to
Next, the main CPU 71 conducts a mystery bonus drawing process (step S15). In this process, a drawing to determine whether or not a mystery bonus trigger is achieved is conducted. For example, the main CPU 71 extracts a mystery bonus random number value from a range of “0 to 99” and, when the extracted random number value is “0”, it is determined that the mystery bonus trigger is achieved.
Next, the main CPU 71 conducts a presentation effects contents determination process (step S16). The main CPU 71 extracts a presentation effects random number value and determines any of a predetermined plurality of presentation effects contents by a drawing.
Next, the main CPU 71 conducts a symbol display control process described later with reference to
Next, the main CPU 71 conducts a number-of-payout determination process described later with reference to
Next, the main CPU 71 determines whether or not the bonus game trigger has been achieved (step S19). When determining that the bonus game trigger has been achieved, the main CPU 71 conducts a bonus game process described later with reference to
Next, after the process at step S20 or upon determining at step S19 that the bonus game trigger has not been achieved, the main CPU 71 determines whether or not a mystery bonus trigger has been achieved (step S21). When determining that the mystery bonus trigger has been achieved, the main CPU 71 conducts a mystery bonus process (step S22). In this process, the number of a payout (for example, 300) set for the mystery bonus is stored on the number-of-payout counter provided in the RAM 73.
After the process at step S22 or upon determining at step S21 that the mystery bonus trigger has not been achieved, the main CPU 71 conducts an insurance check process described later with reference to
Next, the main CPU 71 conducts a paying-out process (step S24). The main CPU 71 adds a value stored on the number-of-payout counter to a value stored on a number-of-credit counter provided in the RAM 73. Based on an input on the CASHOUT switch 33S, driving of the hopper 113 may be controlled, and coins in accordance with the value stored on the number-of-payout counter may be discharged from the coin payout opening 15A. In addition, driving of the ticket printer 171 may be controlled, and a ticket having a bar code having stored thereon the value stored on the number-of-payout counter may be issued. After having conducted this process, the main CPU 71 shifts to step S12.
<Coin-in/Start-Check Process>
Next, with reference to
First, the main CPU 71 determines whether or not the coin counter 92C has detected inputting of coins (step S41). When determining that inputting of the coins has been detected, the main CPU 71 performs an addition of a value of the number-of-credit counter (step S42). The main CPU 71 may determine whether or not the bill validator 115 has detected inputting of bills in addition to the inputting of the coins, and when determining that the inputting of bills has been detected, a value in accordance with the bills may be added to the value stored on the number-of-credit counter.
After step S42 or upon determining at step S41 that the inputting of the coins has not been detected, the main CPU 71 determines whether or not the value stored in the number-of-credit counter is 0 (step S43). When determining that the value stored on the number-of-credit counter is not 0, the main CPU 71 permits acceptance of an operation of any of the BET buttons (step S44).
Next, the main CPU 71 determines whether or not the operation of any of the BET buttons has been detected (step S45). When any of the BET switches detects that any of the BET buttons has been pressed by a player, based on a kind of the pressed BET button, the main CPU 71 performs an addition of a value stored on a number-of-BET counter provided in the RAM 73 and a subtraction of a value stored on the number-of-credit counter (step S46).
Next, the main CPU 71 determines whether or not the value stored on the number-of-BET counter is a maximum (step S47). When determining that the value stored in the number-of-BET counter is the maximum, the main CPU 71 prohibits updating of the value stored in the number-of-BET counter (step S48). After step S48 or upon determining at step S47 that the value stored in the number-of-BET counter is not the maximum, the main CPU 71 permits acceptance of an operation of the SPIN button (step S49).
After step S49, when determining at step S45 that the operation of any of the BET buttons has not been detected or when determining at step S43 that the value stored in the number-of-credit counter is 0, the main CPU 71 determines whether or not the operation of the SPIN button has been detected (step S50). When determining that the operation of the SPIN button has not been detected, the main CPU 71 shifts to step S41.
When determining that the operation of the SPIN button has been detected, the main CPU 71 conducts a jackpot-related process described later with reference to
Next, main CPU 71 conducts an insurance-related process described later with reference to
<Jackpot-Related Process>
Next, with reference to
First, the main CPU 71 calculates a cumulative amount (step S71). The main CPU 71 calculates a product of a value stored in the number-of-BET counter and a cumulative rate, thereby obtaining the cumulative amount into the jackpot amount.
Next, the main CPU 71 transmits the calculated cumulative amount to the external control apparatus 200 (step S72). When receiving the cumulative amount, the external control apparatus 200 updates the jackpot amount. After conducting this process, the jackpot-related process is finished.
<Insurance-Related Process>
Next, with reference to
First, the main CPU 71 determines whether or not an insurance-active flag is on (step S91). The insurance-active flag is set to be on in an insurance selection process described later with reference to
When determining that the insurance-active flag is not on, the main CPU 71 finishes the insurance-related process. On the other hand, when determining that the insurance-active flag is on, the main CPU 71 updates a value stored on an insurance-number-of-game counter provided in the RAM 73 (step S92). The insurance-number-of-game counter is a region for storing the number of games played until the paying-out by the insurance is conducted. In the process at step S92, the main CPU 71 adds one to the value stored in the insurance-number-of-game counter. After conducting this process, the insurance-related process is finished.
<Symbol Drawing Process>
Next, with reference to
First, the main CPU 71 extracts symbol determination random number values (step S111). Next, the main CPU 71 determines symbols scheduled to be stopped of the respective video reels 3 by drawings (step S112). The main CPU 71 conducts the drawings in accordance with the respective video reels 3 and determines any of pluralities of symbols as the symbols scheduled to be stopped. At this time, the respective pluralities of symbols are determined with probabilities which are equal to one another.
Next, the main CPU 71 stores the determined symbols scheduled to be stopped of the respective video reels 3 in a symbol storage region provided in the RAM 73 (step S113). Next, with reference to the symbol combination tables (in
<Symbol Display Control Process>
Next, with reference to
First, the main CPU 71 starts the scrolling of the symbol columns of the respective video reels 3 displayed in the symbol display area 4 of the lower side image display panel 141 (step S131). Next, the main CPU 71 stops the scrolling of the symbol columns of the respective video reels 3 based on the above-described symbol storage region (step S132). After conducting this process, the symbol display control process is finished.
<Number-of-Payout Determination Process>
Next, with reference to
First, the main CPU 71 determines whether or not a combination of symbols is associated with a jackpot (step S151). When determining that the combination of symbols is not associated with the jackpot, the main CPU 71 determines the numbers of payouts corresponding to a LINE payout and a scatter pay (step S152). When losing occurs, “0” is determined as the number of a payout. Next, the main CPU 71 stores the determined numbers of payouts in the number-of-payout counter (step S153). After conducting this process, the number-of-payout determination process is finished.
When determining that the combination of symbols is associated with the jackpot, the main CPU 71 notifies the external control apparatus 200 that the jackpot has occurred (step S154). When having received the notification, the external control apparatus 200 transmits to the slot machine 1 the jackpot amount which has been updated until then. At this time, a portion of the jackpot amount (for example, 80%) may be targeted to be paid out, and the remaining thereof (for example, 20%) may be carried over in preparation for the achievement of the next jackpot trigger.
Next, the main CPU 71 receives the jackpot amount from the external control apparatus 200 (step S155). Next, the main CPU 71 stores the received jackpot amount on the number-of-payout counter (step S156). After conducting this process, the number-of-payout determination process is finished.
<Insurance Check Process>
Next, with reference to
First, the main CPU 71 determines whether or not the insurance-active flag is on (step S171). When determining that the insurance-active flag is not on, the main CPU 71 finishes the insurance check process.
When determining that the insurance-active flag is on, the main CPU 71 determines whether or not a predetermined combination of symbols has been achieved (step S172). In the first embodiment of the present invention, the predetermined combination of symbols is targeted for the “bonus game trigger”, the “jackpot”, and the “mystery bonus”.
When determining that the predetermined combination of symbols has not been achieved, the main CPU 71 determines whether or not a value stored in the insurance-number-of-game counter has reached a predetermined number of times (for example, 300) (step S173). When determining that the value stored in the insurance-number-of-game counter has not reached the predetermined number of times, the main CPU 71 finishes the insurance check process.
When determining that the value stored in the insurance-number-of-game counter has reached the predetermined number of times, the main CPU 71 conducts the paying-out process based on the insurance amount (step S174). The main CPU 71 adds a predetermined amount (for example, 200) as the insurance amount to a value stored on the number-of-credit counter.
After step S174 or upon determining at step S172 that the predetermined combination of symbols has been achieved, the main CPU 71 resets the value stored on the insurance-number-of-game counter (step S175). Next, the main CPU 71 turns off the insurance-active flag (step S176). After conducting this process, the insurance check process is finished.
<Bonus Game Process>
Next, with reference to
First, the main CPU 71 determines the number of bonus games (step S191). The main CPU 71 uniformly determines “8” as the number of bonus games. However, the main CPU 71 may extract random number values for determining the number of bonus games, and determines any of a plurality of the numbers of bonus games, for example “50”, “70”, and “100”, by a drawing.
Next, the main CPU 71 stores the determined number of bonus games on a number-of-bonus game counter provided in the RAM 73 (step S192).
Next, as in the process at step S12 described with reference to
Next, the main CPU 71 determines whether or not a bonus game trigger has been achieved (step S198). When determining that the bonus game trigger has been achieved, the main CPU 71 determines the number of bonus games to be added (step S199). As in the above-described process at step S191, the number of bonus games is determined. Next, the main CPU 71 adds the determined number of bonus games to a value stored on the number-of-bonus game counter (step S200).
After the process at step S200 or upon determining at step S198 that the bonus game trigger has not been achieved, the main CPU 71 conducts the paying-out process (step S201). In this paying-out process, the main CPU 71 adds the value stored on the number-of-payout counter in the above-described number-of-payout determination process at step S197 to a value stored on a bonus-number-of-payout counter. The bonus-number-of-payout counter is a region for storing the total of the number of payouts determined during the bonus games. Upon finishing the bonus game process, the main CPU 71 adds the value stored on the bonus-number-of-payout counter in the paying-out process, at step S24 described with reference to
Next, the main CPU 71 subtracts one from the value stored on the number-of-bonus game counter (step S202). Next, the main CPU 71 determines whether or not the value stored in the number-of-bonus game counter is zero (step S203). When determining that the value stored in the number-of-bonus game counter is not zero, the main CPU 71 shifts to the process at step S193. On the other hand, when determining that the value stored in the number-of-bonus game counter is zero, the main CPU 71 finishes the bonus game process. Upon finishing the bonus game process, the main CPU 71 shifts to the process at step S21 described with reference to
<Insurance Selection Process>
Next, with reference to
First, the main CPU 71 determines whether or not the insurance-active flag is on (step S221). When determining that the insurance-active flag is not on, the main CPU 71 displays an insurance-inactive-image (step S222). The main CPU 71 transmits an instruction to display the insurance-inactive-image to the graphic board 130. Based on the instruction, the graphic board 130 generates the insurance-inactive-image and displays the insurance-inactive-image on the lower side image display panel 141. As the insurance-inactive-image, for example, an image indicating “INSURANCE BET $1.00 TOUCH TO BET” is displayed. This image is to prompt a player to make a selection on whether or not the insurance is made active and to notify a player of an amount required to make the insurance active. By touching a predetermined portion on the touch panel 114, a player can input an instruction indicating that the insurance is made active.
Subsequently, the main CPU 71 determines whether or not there is the input indicating that the insurance is made active (step S223). When determining that there is no input indicating that the insurance is made active, the main CPU 71, with the insurance-active flag being kept off, shifts to step S221. On the other hand, when determining that there is the input indicating that the insurance is made active, the main CPU 71 turns on the insurance-active flag (step S224).
Next, the main CPU 71 subtracts an insurance purchase value from a value stored on the number-of-credit counter (step S225). In the first embodiment of the present invention, for example, a value corresponding to one dollar is subtracted from the value stored on the number-of-credit counter. After step S225 or upon determining at step S221 that the insurance-active flag is on, the main CPU 71 displays an insurance-active image (step S226). As the insurance-active image, for example, an image indicating “INSURANCE-CONTINUING WIN 200 CREDIT” is displayed. This image is to notify a player that the insurance is active and that upon satisfying an insurance condition, a value of “200” is added to a value stored on the number-of-credit counter. After conducting this process, the main CPU 71 shifts to step S221.

On the free game counter 452, words “BONUS REELS IN PLAY” are displayed. In the free games, since the video reel strips which are different from those used in the base game are used, the words “BONUS REELS IN PLAY” are displayed. The words “BONUS REELS IN PLAY” may be hidden by the free game counter 452 or the symbol animation.
On the free game counter 452, a word “FREE” is also displayed. The word “FREE” indicates that each of the free games is being played and, upon starting the spinning in the symbol display area 4 on the lower side image display panel 141, is concurrently expanded to be displayed.
On the free game counter 452, words “xxx OF yyy” are also displayed. On the free game counter 452, a total number of free games and a number of free games which have been currently played are displayed. Upon starting the spinning in the symbol display area 4 on the lower side image display panel 141, the portion of “xxx” is concurrently expanded to be displayed. Further, the portion of “xxx” notifies a player that each of the free games is played on a one-by-one basis. Prior to starting the free games, in the portion of “xxx”, “0” is displayed. Concurrently with the starting of the rotation of the reels in the symbol display area 4 on the lower side image display panel 141, in the portion of “xxx”, “+1” is counted and, concurrently with outputting of a voice, the number is expanded to be displayed. In a portion of “yyy”, the total number of free games is displayed. A maximum number of digits displayed in each of “x” and “y” is one.
On the lower side image display panel 141 during the free games, as performed during the base game, the WIN presentation effects upon the occurrence of any WIN, the increment process, and the LINE presentation effects are performed. With respect to the LINE and BET during the free games, the LINE number and the BET number upon the occurrence of the free games are carried over. A value of the WINs during the free games is added to a value in the WIN meter in an upper right portion of the lower side image display panel 141.
<Appeal Rewriting Upon Starting Spinning During Free Games>
Here, with reference to
In the first embodiment, as shown in
Hereinafter, the description will be made assuming that the tiger is selected in the selection game. However, even when an animal other than the tiger is selected, the same applies thereto. With respect to each of the Reel 1 to Reel 5, a drawing for appeal rewriting is individually conducted, and any reel which has won in the drawing is started in the vicinity of the clusters of the symbols “TIGER” in the frames in the symbol display area 4 upon starting the rotation. Here, the reason why the word “vicinity” of the clusters is used is that in order to avoid arranging the clusters in a straight line each time, a position at which the rewriting is conducted is randomly selected from three positions in the vicinity of the beginnings of the symbols “TIGER” arranged in succession. However, since the drawing for the rewriting is individually conducted with respect to each of the 1 to 5 reels, in reality, there is also some reel which is not started in the vicinity of the symbols “TIGER”.
[Button Look-Ahead Specification]

As shown in
In the WIN gross amount display area 406A, a WIN credit and a money amount are displayed. When the increment is displayed, such increment complies with criteria in a win increment speed sheet. In other words, in the WIN gross amount display area 406A, the number of credits won during the current game cycle (or the previous game cycle) is displayed. When a plurality of credits are won during one game cycle, the credits are sequentially added. For example, when the triggering of the free games occurs during the base game and a player obtains LINE WIN 20 and SCATTER WIN 100, an increment display is conducted from “0” to “120”. Thereafter, when a player obtains a payout of “200” during the free games, the increment display is conducted from “120” to “320”. When the next game cycle is started or losing in the GAMBLE occurs, “0” is displayed. On the other hand, when winning occurs in the GAMBLE, the increment display is not conducted and a doubled amount is instantaneously displayed.
The breakdown display area 406B is related to WIN during the base game and the free games. After the fifth REEL has been stopped, the No. of WIN LINE and a WIN credit are displayed. When a plurality of LINE payouts concurrently occur, displaying is conducted by changing every 0.5 second. The LINE payout is displayed in ascending order of the LINE Nos. and after the LINE payout having the largest WIN LINE No. has been displayed, the LINE payout is displayed again in ascending order of the LINE Nos. In other words, in the breakdown display area 406, a breakdown of the credits won in the spinning conducted this time is displayed. When there are a plurality of elements (different lines or SCATTER), displaying is conducted by changing the display time unit to a unit of 0.5 second. The order of changing the display time unit is from the SCATTER payout to the LINE payout (in ascending order of the LINE Nos.).
In the total display area 406C, upon the completion of the increment in the WIN gross amount display area 406A, a total in the breakdown display area 406B is displayed. However, until after the completion of the increment in the WIN gross amount display area 406A, no value is displayed in the total display area 406C. In other words, in the total display area 406C, the total of the credits won in the spinning conducted this time is displayed. After having finishing the increment in the WIN gross amount display area 406A, a total value is displayed therein.

A second embodiment relates to a gaming machine (slot machine) having a jackpot function. The second embodiment has a configuration common to that of the first embodiment other than a part of the configuration described below, and processes common to those in the first embodiment other than a part of the processes described below are executed.
In the second embodiment, a jackpot is the so-called stand-alone progressive jackpot. In other words, each accumulated money amount (increment value) is individually set for each of the plurality of gaming machine. Accordingly, it is not necessary to manage the occurrence of a jackpot and each accumulated money amount by using a management device such as the external control apparatus 200 via the communication line 301. However, each accumulated money amount accumulated in each of the plurality of gaming machines, the occurrence of a jackpot, and the like, which are related to a jackpot, may be managed in a centralized manner by using a management device such as the external control apparatus 200. Thus, the management can be made easy and the detection of fraudulent acts can be made easy.
In the conventional gaming machine, a money amount based on the number of BETs (BET amount) placed each time is defined as an accumulated money amount for a jackpot. In other words, the larger the number of BETs is, the higher a money amount is accumulated. Therefore, a money amount to be accumulated is calculated based on the number of BETs placed each time and is stored as the accumulated money amount. For example, the calculation of the accumulated money amount is performed each time betting is conducted as follows: accumulated money amount←accumulated money amount+the number of BETs×the number of winning lines targeted for betting×denomination×percentage, and the accumulated money amount is stored.
For example, when the number of BETs is one, 0.5 dollar×1.0%=0.005 dollar is accumulated each time betting is conducted. In this example, the calculation is performed as follows: the number of BETs×the number of winning lines targeted for betting×denomination=0.5 dollar.
When the number of BETs is two, 1 dollar×1.0%=0.01 dollar is accumulated each time betting is conducted. In this example, the calculation is performed as follows: the number of BETs×the number of winning lines targeted for betting×denomination=1 dollar.
When the number of BETs is three, 1.5 dollars×1.0%=0.015 dollar is accumulated each time betting is conducted. In this example, the calculation is performed as follows: the number of BETs×the number of winning lines targeted for betting×denomination=1.5 dollars.
When the number of BETs is five, 2.5 dollars×1.0%=0.025 dollar is accumulated each time betting is conducted. In this example, the calculation is performed as follows: the number of BETs×the number of winning lines targeted for betting×denomination=2.5 dollars.
When the number of BETs is 10, 5.0 dollars×1.0%=0.05 dollar is accumulated each time betting is conducted. In this example, the calculation is performed as follows: the number of BETs×the number of winning lines targeted for betting×denomination=5.0 dollars.
As shown in the above-described examples, in the conventional gaming machine, each time betting is conducted, when the number of BETs is large, the accumulation is conducted with an accumulated money amount being high, and when the number of BETs is small, the accumulation is conducted with an accumulated money amount being low.
Further, when winning of a jackpot occurs, in addition to the accumulated money amount, a base money amount is added thereto, thereby conducting a payout. In the conventional gaming machine, upon winning a jackpot, the base money amount is also multiplied by the number of BETs, and the resultant is added to the accumulated money amount, thereby conducting a payout.
For example, when the number of BETs is one, the multiplication of a base money amount is performed as follows: 100 dollar (=100 dollar×1); when the number of BETs is two, the multiplication of the base money amount is performed as follows: 200 dollar (=100 dollar×2); when the number of BETs is three, the multiplication of the base money amount is performed as follows: 300 dollar (=100 dollar×3); when the number of BETs is five, the multiplication of the base money amount is performed as follows: 500 dollar (=100 dollar×5); and when the number of BETs is ten, the multiplication of the base money amount is performed as follows: 1000 dollar (=100 dollar×10).
Accordingly, when 12.5 dollars is accumulated at the time point when a jackpot is won in the conventional gaming machine and the number of BETs is one, 12.5 dollars+100 dollars=112.5 dollars is paid out. Similarly, when the number of BETs is two, 12.5 dollars+200 dollars=212.5 dollars is paid out; when the number of BETs is three, 12.5 dollars+300 dollars=312.5 dollars is paid out; when the number of BETs is five, 12.5 dollars+500 dollars=512.5 dollars is paid out; and when the number of BETs is 10, 12.5 dollars+1000 dollars=1012.5 dollars is paid out. As described above, the payout is conducted such that the larger the number of BETs is, the higher both of the accumulated money amount and the base money amount are, and the smaller the number of BETs is, the lower the both of the accumulated money amount and the base money amount are.
In the conventional gaming machine, each money amount based on the number of BETs each time betting is conducted is accumulated and made an accumulated money amount, and upon winning a jackpot, the calculation with respect to a base money amount is also performed based on the number of BETs to obtain a money amount to be paid out, thereby conducting a payout.
It is preferable that a player is provided with a benefit in accordance with an investment made by the player by paying out a large amount of a jackpot to a player who is proceeding with a game by placing a large number of BETs and by paying out a small amount of a jackpot to a player who is proceeding with a game by placing a small number of BETs.
However, in the conventional gaming machine, when a player who has continued to make an investment in the expectation of winning a jackpot does not win a jackpot while playing a game, despite the investment made until then, no benefit can be provided for the player. Furthermore, it is likely to provide a benefit awarded by a jackpot for another player who thereafter starts a game. Therefore, unfairness may result between a player who has made an investment and a player who has not made an investment.
Further, in the conventional gaming machine, since each money amount accumulated by using the number of BETs each time betting is conducted is added and stored, a complicated process is executed.
In consideration of the conventional gaming machine described above, the gaming machine according to the second embodiment was made. In the gaming machine according to the second embodiment, each accumulated money amount is the same money amount independent of the number of BETs placed by a BET operation (part (a) of
In part (a) of
Upon the occurrence of a jackpot (part (b) of
As described above, upon winning a jackpot, based on the number of BETs, the accumulated money amount and the base money amount are calculated together, thereby allowing the process to be made easy. In addition, each of the respective accumulated money amounts is the same independently of the number of BETs placed by the BET operation, whereby the unfairness which may result between a player who has made an investment and a player who has not made an investment can be made small.
In the second embodiment, BET/LINE, that is, the number of BETs per payline is referred to as the number of BETs. Accordingly, a total number of BETs is a number calculated multiplying the numbers of the paylines by the numbers of BETs. For example, a player can start a slot game by selecting any of numbers 1, 2, 3, 4, or 5 as the number of BETs in each unit game. For example, when 4 is selected as the number of BETs, the number of credits, which is 4, is bet per payline. Accordingly, the total number of BETs is a number calculated by multiplying the numbers of paylines by 4.
In addition, in the second embodiment, all of the paylines are targeted for betting. For example, there are 50 paylines and these 50 paylines are invariably targeted for betting. Accordingly, when 3 is selected as the number of BETs, the number of BETs per payline is 3. In this unit game, 50×3=150 is bet as the total numbers of BETs, and a unit game is started.
In the second embodiment, a money amount, as a money amount for accumulating, which is smaller than a money amount corresponding to a minimum number of BETs is previously set. This money amount is constant even when the number of BETs per line is large or even when the number of BETs per line is small, accumulation and addition of the money amount are performed each time a player operates any of BET buttons.
In other words, although the money amount which is accumulated each time betting is conducted is the same irrespective of the number of BETs, an accumulated money amount which is finally awarded by a jackpot becomes a money amount in accordance with the number of BETs. Accordingly, the larger the number of BETs is, the larger the finally paid-out accumulated money amount is, and the smaller the number of BETs is, the smaller the finally paid-out accumulated money amount is.
<<Setting of BET CONFIG.>>
In the gaming machine according to the second embodiment, BET CONFIG. can be set. The BET CONFIG. is to set BET/LINE combinations. For example, in a first BET CONFIG., a combination of BET/LINE is a combination of 1, 2, 3, 4, and 5. In a second BET CONFIG, a combination of BET/LINE is a combination of 1, 2, 3, 5, and 10. In a third BET CONFIG., a combination of BET/LINE is a combination of 1, 2, 5, 10, and 15. In a fourth BET CONFIG., a combination of BET/LINE is a combination of 1, 2, 5, 10, and 20.
For example, when the third BET CONFIG is set, a player selects any one of 1, 2, 5, 10, or 15 as the number of BETs and can start a unit game.
The BET CONFIG. is set by an operation conducted by an employee of a gaming arcade such as a casino. For example, upon activating a gaming machine or the like, an employee of a casino or the like sets the BET CONFIG. Setting of the BET CONFIG. can be made by operating a variety of buttons located on the control panel 30.
The BET CONFIG. can also be set by a management device such as the external control apparatus 200. A gaming machine is communicably connected to the management device such as the external control apparatus 200 via a network. By using the management device to set the BET CONFIG., the setting can be made collectively and easily.
First, one BET CONFIG. is selected (step S10011). As described above, one BET CONFIG. is selected by the operation conducted by an employee of a gaming arcade such as a casino, or by using the management device such as the external control apparatus 200, or the like. In the gaming machine according to the second embodiment, one BET CONFIG. is selected from among the above-mentioned first BET CONFIG. to the fourth BET CONFIG.
Next, in accordance with the selected BET CONFIG., a percentage is determined (step S10013). In the second embodiment, an increment percentage of a jackpot is referred to the percentage. Each money amount in accordance with this percentage is accumulated each time betting is conducted. As described above, each of the accumulated money amounts is independent of the number of BETs. The further details will be described in the description of a process shown in
In the second embodiment, each percentage can be determined in accordance with the BET CONFIG.
The selection of each percentage is also set by an operation conducted by an employee of a gaming arcade such as a casino. For example, upon activating the gaming machine, the employee of a casino sets each percentage together with the setting of the BET CONFIG.
As with the BET CONFIG., each percentage can also be set by using the management device such as the external control apparatus 200. By using the management device to set each percentage, the setting can be made collectively and easily.
A percentage which cannot be selected (each cell indicated by a x mark) in
Next, a denomination is set (step S10015). In the second embodiment, a money amount per coin (per credit) is referred to as the denomination. For example, the denomination can be set within a range of 0.01 dollar to 10.00 dollars.
The denomination also is set by an operation conducted by an employee of a gaming arcade such as a casino. For example, upon activating the gaming machine, the employee of a casino sets the denomination together with the setting of the BET CONFIG.
As with the BET CONFIG., the denomination can also be set by using the management device such as the external control apparatus 200. By using the management device to set the denomination, the setting can be made collectively and easily.
The BET CONFIG. selected in the process at step S10011 is stored in a predetermined region of the RAM 73 (step S10017).
Next, the percentage selected in the process at step S10013 is stored in a predetermined region of the RAM 73 (step S10019).
Next, the denomination set in the process at step S10015 is stored in a predetermined region of the RAM 73 (step S10021).
In the above-described example, a case where the BET CONFIG., the percentage, and the denomination are set by an employee of a gaming arcade such as a casino or by using the management device such as the external control apparatus 200 is described. However, the settings may be made by a player, thereby allowing a player to play a game under his or her desired conditions.
<<Jackpot-Related Process>>
First, the percentage stored in the RAM 73 is read out (step S10313). This percentage has been stored in the RAM 73 by the process at step S10019 in
Next, the main CPU 71 reads out a value stored in a number-of-BET counter (step S10315). This allows the number of BETs to be obtained.
Next, the main CPU 71 reads out a denomination (step S10317). This allows the number of BETs to be obtained. This denomination has been stored in the RAM 73 by the process at step S10021 in
Next, the main CPU 71 calculates a BET money amount (step S10319). The BET money amount can be calculated as follows: BET money amount=the number of BETs×the number of paylines targeted for betting×denomination. As described above, in the second embodiment, the paylines targeted for betting are all of the paylines and specifically, the number thereof is 50 lines. Accordingly, the calculation can be made as follows: BET money amount=the number of BETs×50×denomination.
Next, the main CPU 71 accumulates the accumulated money amount (step S10321). The accumulated money amount can be accumulated as follows: accumulated money amount←accumulated money amount+BET money amount×percentage/the number of BETs. As described above, when the accumulated money amount is accumulated, since the division by the number of BETs is performed, a constant money amount can be accumulated as the accumulated money amount independent of the number of BETs.
In the second embodiment, BET money amount×percentage/the number of BETs is referred to as a progressive money amount. Specifically, the progressive money amount is a value calculated as follows: “the number of paylines×the number of BETs×denomination×percentage/the number of BETs”.
For example, when the number of BETs is one, that is, when the number of BETs (BET/LINE) per payline is one, a percentage is 0.6%, and a denomination is 1 cent, a progressive money amount is calculated as follows: 50 (lines)×1 (the number of BETs)×1 (cent)×0.006 (percentage)/1 (the number of BETs)=0.3 cent. This 0.3 cent is accumulated each time betting is conducted.
In addition, when the number of BETs is 10, that is, when the number of BETs (BET/LINE) per payline is 10, a percentage is 0.6%, and a denomination is 1 cent, a progressive money amount is calculated as follows: 50 (lines)×10 (the number of BETs)×1 (cent)×0.006 (percentage)/10 (the number of BETs)=0.3 cent. This 0.3 cent is accumulated each time betting is conducted.
As described above, even when the number of BETs is one and even when the number of BETs is 10, the same amount 0.3 cent is each accumulated. In this way, in the second embodiment, since an amount obtained by the division by the number of BETs is defined as the progressive money amount, a constant money amount can be each accumulated independently of the number of BETs.
In the above-described example, the case in which the BET money amount is calculated at step S10319 and the accumulated money amount is each accumulated at step S10321 is described. However, the accumulated money amount may be accumulated at once. For example, the accumulated money amount may be as follows: the accumulated money amount←accumulated money amount+the number of paylines targeted for betting×denomination×percentage. As described above, in the expression: the number of paylines targeted for betting×denomination×percentage, the number of BETs is not included, and the accumulated money amount is constant and is a money amount accumulated each time betting is conducted.
Next, the main CPU 71 stores each of the accumulated money amounts accumulated at step S10321 for each of the kinds of the animals in the RAM 73 (step S10323) and finishes this subroutine.
As described later, in the second embodiment, at the timing when the symbols of one of the kinds of animals are rearranged in all of the areas of the symbol display region 4, a jackpot is won. In the second embodiment, there are the five kinds of symbols of animals: a lion, a tiger, a panther, a leopard, and a cheetah. For example, at the timing when the symbols of the lion are rearranged in all of the areas of the symbol display region 4 (refer to
In the second embodiment, in addition thereto, at the timing when the symbols of the tiger are rearranged in all of the areas of the symbol display region 4, a tiger jackpot is won; at the timing when the symbols of the panther are rearranged in all of the areas of the symbol display region 4, a panther jackpot is won; at the timing when the symbols of the leopard are rearranged in all of the areas of the symbol display region 4, a leopard jackpot is won; and at the timing when the symbols of the panther are rearranged in all of the areas of the symbol display region 4, a panther jackpot is won; at the timing when the symbols of the cheetah are rearranged in all of the areas of the symbol display region 4, a cheetah jackpot is won.
As described above, even after a jackpot has won by the symbols of one of the kinds of animals, a likelihood with which a jackpot is won by the symbols of another of the kinds of animals remains. Therefore, an incentive to continuously proceed with a game can be provided for a player.
As described above, in the second embodiment, a jackpot is generated for each of the kinds of animals. In the process at step S10323, the accumulated money amount for each of the kinds of animals is stored. In other words, a storage area in the RAM 73 is allocated for each of the kinds of animals, and each accumulated money amount is stored in each storage area, respectively (refer to part (a) of
As described above, part (a) of
As described above, in the gaming machine 1, the upper side image display panel 131 is provided. In the process at step S10323, each accumulated money amount is stored in the RAM 73, and concurrently therewith, on the upper side image display panel 131, each accumulated money amount may be displayed. In this case, it is preferable that with respect to each of the lion, the tiger, the panther, the leopard, and the cheetah, each accumulated money amount is displayed, respectively. At that time point, a player can visually recognize an animal whose accumulated money amount is large and the accumulated money amount of that animal. Thus, a player is allowed to have expectations of the occurrence of a jackpot, thereby allowing a motivation to continue a game to be provided for a player.
<<Jackpot-Occurrence-Time Process>>
The number-of-payout determination process shown in
When determining in a determination process at step S151 in
In the second embodiment, in the determination process at step S151 in
In the second embodiment, a jackpot occurs independently of the number of BETs, and a probability with which a jackpot occurs is constant. In the second embodiment, at the timing when symbols of one of the kinds of animals are rearranged in all of the areas of the symbol display region 4, a jackpot is won. In other words, a probability with which symbols of one of the kinds of animals are rearranged in all of the areas of the symbol display region 4 is constant independently of the number of BETs.
In the second embodiment, there are the five kinds of animals: the lion, the tiger, the panther, the leopard and the cheetah. Accordingly, a probability with which symbols of one of the lion, the tiger, the panther, the leopard and the cheetah are rearranged in all of the areas of the symbol display region 4 is constant independently of the number of BETs.
Probabilities, with each of which symbols of one of the lion, the tiger, the panther, the leopard and the cheetah are rearranged in all of the areas of the symbol display region 4, can be made different from one another in accordance with the kinds of animals. For example, a probability with which the symbols of the lion are rearranged in all of the areas of the symbol display region 4 can be made the lowest; a probability with which the symbols of the tiger are rearranged in all of the areas of the symbol display region 4 can be made the second lowest; a probability with which the symbols of the panther are rearranged in all of the areas of the symbol display region 4 can be made the third lowest; a probability with which the symbols of the leopard are rearranged in all of the areas of the symbol display region 4 can be made the fourth lowest; and a probability with which the symbols of the cheetah are rearranged in all of the areas of the symbol display region 4 can be made the highest. Thus, the probability with which the symbols of the cheetah are rearranged in all of the areas of the symbol display region 4 and a jackpot thereby occurs can be made the highest, and the probability with which the symbols of the lion are rearranged in all of the areas of the symbol display region 4 and a jackpot thereby occurs can be made the lowest.
For example, in the second embodiment, as shown in
This can impart variations to winning of a jackpot, and thus, a player is allowed to have expectations of the occurrence of a jackpot, thereby allowing a motivation to continue a game to be provided for a player.
First, the main CPU 71 determines whether or not symbols of one of the lion, the tiger, the panther, the leopard and the cheetah are rearranged in all of the areas of the symbol display region 4 (step S10411). In other words, the main CPU 71 determines whether or not a jackpot is won.
For example, as shown in
In addition, as shown in
When determining that symbols of one of the kinds of animals are not rearranged in all of the areas of the symbol display region 4 (NO), the main CPU 71 immediately finishes this subroutine.
Next, the main CPU 71 reads out a value stored in the number-of-BET counter (step S10413). Thus, the number of BETs can be obtained.
Next, the main CPU 71 reads out a base money amount (step S10415).
Specifically, a maximum number of BETs in the first BET CONFIG. (1, 2, 3, 4, and 5) is 5. A maximum number of BETs in the second BET CONFIG. (1, 2, 3, 5, and 10) is 10. A maximum number of BETs in the third BET CONFIG. (1, 2, 5, 10, and 15) is 15. A maximum number of BETs in the fourth BET CONFIG. (1, 2, 5, 10, and 20) is 20.
In the second embodiment, each base money amount is defined as follows: (maximum number of BETs)×(number of paylines)×(payout when five symbols of an animal targeted for betting are rearranged). In a case of the lion, each of the base money amount is defined to be doubled as follows: (maximum number of BETs)×(number of paylines)×(payout awarded when five symbols of an animal targeted for betting are rearranged)×2.
Next, the main CPU 71 determines whether or not the slot game is the free games (step S10417). When determining that the slot game is not the free games (NO), that is, when the slot game is the base game, the main CPU 71 calculates a payout money amount (step S10419). Subsequently, the main CPU 71 stores the payout money amount in the number-of-payout counter (step S10420). The process at this step S10420 is the same as the process at step S156 in
In the process at step S10419, the payout money amount can be calculated as follows: (base money amount+accumulated money amount)×the number of BETs. Here, the accumulated money amount is the money amount calculated at step S10321 in
Here, the number of BETs is the number of BETs placed in a unit game played when a jackpot has been won. In other words, the number of BETs here is the number of BETs placed to initiate the unit game causing the jackpot to occur. Accordingly, a large payout amount can be provided for a player who has placed a large number of BETs in the unit game to play the game.
In the second embodiment, the occurrence of a jackpot is determined by a symbol drawing process at step S14 in
Accordingly, a player cannot adjust easiness of winning of a jackpot by differentiating the numbers of BETs. However, as in the description for step S10419, the payout money amount is the money amount calculated by the multiplication by the number of BETs. Accordingly, in order for a player to try to assuredly obtain a large benefit by winning of a jackpot, it is required for a player to place a large number of BETs. By employing the above-described configuration, a motivation to invariably place a large number of BETs can be provided for a player, thereby bringing about a likelihood that a shop such as a casino can ensure a profit. In addition, upon winning a jackpot by placing a large number of BETs, a money amount paid out to a player can be made large through the multiplication by the large number of BETs, thereby allowing also a player's benefit to be ensured. As described above, a balance between the profit of a shop and the benefit of a player can be attained.
In the above-described example, the case where as the number of BETs for determining the payout money amount of a jackpot, the number of BETs placed in the unit game upon winning the jackpot is used is described. However, without using the above-mentioned number of BETs, an average value of the numbers of BETs may be used. The average value of the numbers of BETs placed each time betting is conducted is calculated and stored in the RAM 73. Upon winning a jackpot, the average value of the numbers of BETs may be read out from the RAM 73 and used. In order to make a average value of the numbers of BETs large, it is required to initiate a unit game by placing a large number of BETs. Accordingly, even in the case where the average value of the numbers of BETs is used, a motivation to invariably place a large number of BETs can be provided for a player.
Next, the main CPU 71 initializes the accumulated money amount corresponding to the animal which has caused the winning of a jackpot (step S10421) and finishes this subroutine. Accordingly, starting from when a next betting operation is performed, for the accumulated money amount corresponding to the animal which has caused the winning of the jackpot, accumulation is newly started.
On the other hand, each accumulated money amount corresponding to each of the animals which have not caused any winning of a jackpot is not initialized. Accordingly, each accumulated money amount corresponding to each of the animals which have not caused any winning of a jackpot remains as it is, and accumulation is subsequently conducted in a carried-over manner each time betting is conducted. By employing this configuration, a likelihood with which each of the animals which have not caused any winning of a jackpot this time is likely to cause winning of a jackpot and bring about a benefit in the near future can be sustained, thereby allowing a motivation to subsequently play a game to be provided for a player.
In the determination process at step S10417, when determining that the slot game is the free games (YES), the main CPU 71 counts the number of times at which a jackpot has been won in the free games (step S10423).
Next, the main CPU 71 determines whether or not the number of times at which a jackpot has been won in the free games is larger than two (step S10425). When determining that the number of times at which a jackpot has been won in the free games is not larger than two (NO), that is, when determining that the number of times at which a jackpot has been won in the free games is less than or equal to one, the main CPU 71 shifts the process to the above-described step S10419.
As described above, when the number of times at which a jackpot has been won in the free games is less than or equal to one, a payout money amount is calculated as follows: (base money amount+accumulated money amount)×the number of BETs. In other words, the same money amount as in the base game is calculated. In this case, the number of BETs is the number of BETs placed in a unit game which has caused a shift to the free games. Since each of the free games is a game which can be initiated without betting, the number of BETs cannot be determined. Therefore, upon first winning a jackpot during the free games, the number of BETs in the unit game which has caused the shift to the free games is used. As described above, even during the free games, upon first winning a jackpot, the same benefit as in the base game is provided for a player. By employing this configuration, a benefit can be provided for a player who has continued an investment in the base game before starting the free games.
In the determination process at step S10425, when determining that the number of times at which a jackpot has been won in the free games is larger than two (YES), the main CPU 71 determines only the base money amount as a payout money amount (step S10427) and shifts the process to step S10420.
Since each of the free games is a game which can be initiated without betting, a player can proceed with a game without consuming coins (credits). In other words, since no investment is made during the free games, when the number of times at which a jackpot has been won in the free games is greater than or equal to two, the addition of the accumulated money amount and the multiplication by the number of BETs are not performed, and only the base money amount is determined as the payout money amount. By employing this configuration, excessively providing a benefit for a player can be prevented, thereby also preventing a disadvantage for a shop such as a casino.
[Others]
The present invention is not limited to the above-described embodiments, and numerous other modifications and variations can be devised without departing from the scope of the invention.
For example, instead of the animal symbols, symbols of human images may be used. In this case, as a background image related to each character symbol, clothing which a human of an image selected in the selection game wears may be displayed.
