20160063803
This application claims the benefit of Japanese Pat. App. No. 2014-176161, filed on Aug. 29, 2014, which application is incorporated herein by reference in its entirety.
The present invention relates to a gaming machine which is configured to execute a normal game and a free game shifted from the normal game.
A known gaming machine is arranged such that the execution of a free game is awarded when a trigger is generated in a normal game. For example, when the gaming machine is a slot machine, a video reel used in the free game and a video reel used in the normal game may be of different types. In such a case, when the video reel used in the free game is upgraded, the player becomes more likely to obtain a winning combination (see e.g., Patent Literature 1 (U.S. Patent Publication No. 2012/0172106)).
However, when the upgrade of the video reel used in the free game is, for example, mere increase in the number of wild symbols each being able to substitute for any symbols, such an increase is monotonous for the player.
An object of the present invention is therefore to provide a gaming machine which achieves a new mode of upgrade of a video reel which is used after shifting from a normal game to a free game.
The present invention relates to a gaming machine configured to execute a normal game and a free game shifted from the normal game, including:
a display device configured to display a game result by rearranging a video reel group in which symbols are laid out;
a video reel group storage configured to store video reel groups which are different from one another in how the symbols are laid out;
a table storage which is configured to store a free game type table in which free game types are associated with video reel groups, respectively, in the free game types the numbers of times of execution of the free game being associated with payouts for the game result so that the number of times of execution of the free game decreases as the payout for the game result increases, and the symbols being laid out in the video reel groups so that the video reel groups are identical with one another in overall expectation of the payout when the free game is executed for the number of times in accordance with the payout for the game result;
an input device; and
a controller,
the controller being programmed to execute the processes of: (1A) as the normal game, randomly determining the symbols which are to be rearranged on the display device; (1B) rearranging the symbols determined in the process (1A) on the display device and awarding a benefit in accordance with a combination of the rearranged symbols; (1C) when the awarded benefit is the right to execute the free game, displaying, on the display device, options corresponding to the respective free game types and receiving selection of one of the options through the input device; (1D) setting the video reel group corresponding to the free game type selected in the process (1C) to be used in the free game; (1E) as the free game, randomly determining the symbols which are to be rearranged on the display device; (1F) rearranging the symbols determined in the process (1E) on the display device and awarding a benefit of the free game with reference to the payout for the game result corresponding to the free game type selected in the process (1C) and based on a combination of the rearranged symbols; and (1G) repeating the processes (1E) to (1F) for the number of times corresponding to the free game type selected in the process (1C).
According to the arrangement above, the video reel groups are associated with the payouts for the game result and the numbers of times of execution of the free game, and the number of times of execution of the free game decreases as the payout for the game result increases.
On this account, when, for example, the free game is executed with the video reel group with a high payout, the number of times of execution of the free game is small. To put it differently, the player is able to enjoy the free game with a high payout in a short time.
In the meanwhile, when the free game is executed with the video reel group with a low payout, the number of times of execution of the free game is large. To put it differently, the player is able to enjoy the free game for a relatively long time with a low payout.
Because in the video reel groups the symbols are laid out so that the overall expectation of the payout when the free game is executed for the executable number of times is identical no matter whether the video reel group with a high payout and a small number of times of execution of the free game or the video reel group with a low payout and a larger number of times of execution of the free game is used, the player can enjoy the free game in various modes with different payout amounts and different numbers of times of execution of the free game, while the fairness of the payout in the free game is maintained.
In addition to the above, the present invention relates to the above-described gaming machine, and the payout for the game result in the free game type table stored in the storage indicates a payout rate for the payout.
According to the arrangement above, the video reel groups are associated with the payout rates for the game result and the numbers of times of execution of the free game, and the number of times of execution of the free game decreases as the payout rate for the game result increases.
In addition to the above, the present invention relates to the above-described gaming machine, and in the process (1C), when the awarded benefit is the right to execute the free game, one of the free game types is randomly selected.
According to this arrangement, the payout for the game result, the number of times of execution of the free game, and the free game type associated with the video reel group are randomly determined. This allows the player to enjoy the random determination of the payout amount and the number of times of execution of the free game.
In addition to the above, the present invention relates to a method of controlling a gaming machine which is configured to execute a normal game and a free game shifted from the normal game, the gaming machine including:
a display device configured to display a game result by rearranging a video reel group in which symbols are laid out;
a video reel group storage configured to store video reel groups which are different from one another in how the symbols are laid out;
a table storage which is configured to store a free game type table in which free game types are associated with video reel groups, respectively, in the free game types the numbers of times of execution of the free game being associated with payouts for the game result so that the number of times of execution of the free game decreases as the payout for the game result increases, and the symbols being laid out in the video reel groups so that the video reel groups are identical with one another in overall expectation of the payout when the free game is executed for the number of times in accordance with the payout for the game result;
an input device; and
a controller,
the method comprising the steps, performed under the control of the controller, of: (2A) as the normal game, randomly determining the symbols which are to be rearranged on the display device; (2B) rearranging the symbols determined in the step (2A) on the display device and awarding a benefit in accordance with a combination of the rearranged symbols; (2C) when the awarded benefit is the right to execute the free game, displaying, on the display device, options corresponding to the respective free game types and receiving selection of one of the options through the input device; (2D) setting the video reel group corresponding to the free game type selected in the step (2C) to be used in the free game; (2E) as the free game, randomly determining the symbols which are to be rearranged on the display device; (2F) rearranging the symbols determined in the step (2E) on the display device and awarding a benefit of the free game with reference to the payout for the game result corresponding to the free game type selected in the step (2C) and based on a combination of the rearranged symbols; and (2G) repeating the steps (2E) to (2F) for the number of times corresponding to the free game type selected in the step (2C).
According to the method above, the video reel groups are associated with the payouts for the game result and the numbers of times of execution of the free game, and the number of times of execution of the free game decreases as the payout for the game result increases.
On this account, when, for example, the free game is executed with the video reel group with a high payout, the number of times of execution of the free game is small. To put it differently, the player is able to enjoy the free game with a high payout in a short time.
In the meanwhile, when the free game is executed with the video reel group with a low payout, the number of times of execution of the free game is large. To put it differently, the player is able to enjoy the free game for a relatively long time with a low payout.
Because in the video reel groups the symbols are laid out so that the overall expectation of the payout when the free game is executed for the executable number of times is identical no matter whether the video reel group with a high payout and a small number of times of execution of the free game or the video reel group with a low payout and a larger number of times of execution of the free game is used, the player can enjoy the free game in various modes with different payout amounts and different numbers of times of execution of the free game, while the fairness of the payout in the free game is maintained.
A gaming machine which achieves a new mode of upgrade of a video reel which is used after shifting from a normal game to a free game is provided.
The following will describe a gaming machine of the present invention with reference to figures. As shown in
The slot game is of a line type (Left to Right). To be more specific, 50 paylines are set in a matrix of four rows and five columns on a display device (lower image display panel). The slot game employs video reels. The video reels include five reels. That is to say, the video reels include the first reel, the second reel, the third reel, the fourth reel, and the fifth reel.
In the normal game, video reels for the normal game are used. In the free game, video reels for the free game are used. In the free game, free game video reels which are selected immediately after the shifting from the normal game to the free game are used. There are five types (A type to E type: free game types) of the free game video reels, and these types are different from one another in the arrangement of symbols (types of symbols, total number of symbols, arranged locations of symbols, or the like).
In the normal game, symbols laid out on a normal game video reel strip, which are rearranged on the display device, are randomly selected, the randomly selected symbols are rearranged on the display device, and a benefit is awarded based on the combination of the symbols rearranged on a payline (S1).
When, rearrangement results in awarding of the right to execute the free game (free game trigger) on account of the rearrangement of three FEATURE symbols in the matrix of four rows and five columns (S2), the player selects one of five options (A to E in
Thereafter, the number of times of execution of the free game corresponding to the type of the video reels selected in (S3) is awarded, and the payout rate is set in accordance with the type of the video reels selected in (S3) (S4).
Subsequently, by using the video reels selected in (S3), symbols to be rearranged on the display device are randomly determined as the free game, the determined symbols are rearranged on the display device, and a benefit of the free game is awarded in accordance with a combination of the symbols rearranged on a payline (S5).
In S5, the free game is executed for the number of times of execution of the free game awarded in S4. As the benefit of the free game, a payout is awarded based on the payout rate set in S4. After the execution of the free game for the number of times awarded in S4, the free game is terminated and is shifted to the normal game.
(Definitions or the Like)
The slot machine is a type of a gaming machine. While the present embodiment deals with the slot machine as an example of the gaming machine, the slot machine may be a different type of machine on condition that a normal game can be individually run by the machine and a free game developing from the normal game can be run by the machine.
A normal game of the present embodiment is run by the slot machine. The normal game is a slot game of rearranging symbols.
The symbols encompass “WILD”, “POSEIDON”, “DOLPHIN”, “TURTLE”, “SEAHORSE”, “SEASHELL”, “ACE”, “KING”, “QUEEN”, “JACK”, “TEN”, “NINE”, and “FEATURE” symbols.
A coin, a bill, or electrically valuable information corresponding to these is used as a game value. It is to be noted that the game value in the disclosure is not limited to these, and for example a game medium such as a medal, a token, electric money or the like can be adopted. Further, a later-described ticket with a barcode is also used.
The free game of the present embodiment may be any type of game on condition that the gaming state thereof is different from that of the normal game. The free game is a game which is executable with a smaller amount of game values bet than in the normal game. The expression “executable with a smaller amount of game value bet ” includes a case where an amount of game values bet is zero. Therefore, the free game may be a game which is run without betting a game value and the game value is paid out for an amount corresponding to rearranged symbols. In other words, the free game may be a game that starts even if no game value is consumed. On the other hand, the normal game is run on condition that a game value is bet, and is a game of paying out a game value for an amount corresponding to rearranged symbols. In other words, the normal game is a game that starts with the consumption of the game value.
The term “rearrangement” indicates that the symbols are rearranged after the arrangement of the symbols is dismissed. The term “arrangement” indicates a state in which the symbols are visually recognizable by an external player.
[Explanation of Function Flow Diagram]
The following describes basic functions of the slot machine of the present invention, with reference to
(Coin-Insertion/Start-Check Process)
First, the slot machine checks whether or not a BET button has been pressed by a player, and subsequently checks whether or not a spin button has been pressed by the player.
<Symbol Determination>
Next, when a spin button has been pressed by the player, the slot machine extracts a random number for symbol determination, and determines symbols to be displayed for the player at the time of stopping the scroll of the symbol column, for respective video reels displayed on a display.
<Symbol Display>
Then the slot machine starts the scroll of the symbol column of each video reel, and stops the scroll so that the determined symbols 501 are displayed for the player.
<Win Determination>
Subsequently, as the rotation of the symbol column of each video reel is stopped, the slot machine determines whether the combination of the symbols displayed for the player is a combination related to win.
<Payout>
When the combination of the symbols displayed for the player is a combination related to winning, the slot machine offers, to the player, benefit according to the combination. For example, when a combination of symbols related to a payout of coins has been displayed, the slot machine pays out coins of the number corresponding to the combination of symbols to the player.
When a combination of symbols associated with a free game trigger is displayed, the slot machine starts the free game. In the embodiment of the present invention, as the free game, a game (free game) in which the random determination of the above-described to-be stopped symbols is carried out for a predetermined number of times without the consumption of coins is executed.
When a combination of symbols associated with a jackpot trigger is displayed, the slot machine may pay out coins corresponding to a jackpot amount to the player. As the jackpot, at least one of the coins consumed by the player at each slot machine is accumulated as a jackpot amount, and when the jackpot trigger is established at a slot machine, coins corresponding to the accumulated jackpot amount are paid out to that slot machine. In the present case, the slot machine calculates an amount (accumulative amount) accumulated to the jackpot amount each time the game is played, and sends the calculation result to an external controller. The external controller adds the accumulative amount sent from each slot machine to the jackpot amount.
In addition to the above, the slot machine may have other benefits such as mystery bonus and insurance, in addition to the benefit above. In the mystery bonus, a predetermined number of coins are paid out when a win is achieved in dedicated random determination. When a spin button is pressed, the slot machine samples a random number for the mystery bonus, and whether a mystery bonus trigger is established is randomly determined.
The insurance is a function for saving the player when the free game is not executed for a long period of time. In the embodiment of the present invention, the player is able to determine whether to activate the insurance at will. When the insurance is activated, a predetermined insurance activation amount must be paid. When the insurance is activated, the slot machine starts to count the number of times of execution of the game. When the counted number of times reaches a predetermined number while a large amount of payout on account of the free game or the like is not carried out, the slot machine pays out coins, the number of which corresponds to the amount set for the insurance.
<Determination of Effect>
The slot machine produces an effect by displaying an image on a display, outputting light from a lamp, and outputting sound from a speaker. The slot machine samples an effect-use random number and determines the content of an effect based on randomly determined symbols or the like.

<Structures of Circuits Provided to Slot Machine>
Next, with reference to
A gaming board 50 is provided with a CPU 51, a ROM 52, and a boot ROM 53, which are mutually connected by an internal bus; a card slot 55 corresponding to a memory card 54; and an IC socket 57 corresponding to a GAL (Generic Array Logic) 56.
The memory card 54 includes a nonvolatile memory, and stores a game program and a game system program. The game program includes a program related to game progression, a random determination program, and a program for producing effects by images and sounds. Furthermore, the game program includes data (see
The random determination program is a program for randomly determining to-be stopped symbol on the video reels 3. The to-be stopped symbol is data for determining four symbols to be displayed to the symbol display region 4 out of plural symbols forming each symbol column. The slot machine 1 of the embodiment of the present invention determines, as the to-be stopped symbol, the symbols to be displayed in a predetermined area (e.g. the uppermost stage) out of the four areas provided for each of the video reels 151-155 of the symbol display region 4.
The aforementioned random determination program includes symbol determination data. The symbol determination data is data that specifies random numbers so that each of the symbols forming the symbol column is determined at an equal probability for each of the video reels 3. For example, for the first video reel (“Reel 1”) 3a of the normal game video reel shown in
Further, the card slot 55 is configured so that the memory card 54 can be inserted thereinto and removed therefrom, and is connected to a motherboard 70 by an IDE bus.
The GAL 56 is a type of PLD (programmable Logic Device) having a fixed OR array structure. The GAL 56 is provided with a plurality of input ports and output ports, and predetermined input into the input port causes output of the corresponding data from the output port.
Further, the IC socket 57 is configured so that the GAL 56 can be inserted thereinto and removed therefrom, and is connected to the motherboard 70 by a PCI bus. The contents and settings of the game to be played on the slot machine 1 can be changed by replacing the memory card 54 with another memory card 54 having another program written therein or by rewriting the program written into the memory card 54 as another program.
The CPU 51, the ROM 52 and the boot ROM 53 mutually connected by the internal bus are connected to the motherboard 70 by a PCI bus. The PCI bus enables a signal transmission between the motherboard 70 and the gaming board 50, and power supply from the motherboard 70 to the gaming board 50.
The ROM 52 stores an authentication program. The boot ROM 53 stores a pre-authentication program, a program (boot code) to be used by the CPU 51 for activating the pre-authentication program, and the like. The authentication program is a program (falsification check program) for authenticating the game program and the game system program. The pre-authentication program is a program for authenticating the aforementioned authentication program. The authentication program and the pre-authentication program are written along a procedure (authentication procedure) for proving that the program to be the subject has not been falsified.
The motherboard 70 is provided with a main CPU 71, a ROM 72, a RAM 73, and a communication interface 82.
The ROM 72 includes a memory device such as a flash memory, and stores a program such as BIOS to be executed by the main CPU 71, and permanent data. When the BIOS is executed by the main CPU 71, a process for initializing predetermined peripheral devices is executed. Further, through the gaming board 50, a process of loading the game program and the game system program stored in the memory card 54 is started.
The processor of the present invention includes the main CPU 71, the ROM 72, and the RAM 73 above and the memory card 54 storing the game program and the game system program, and controls the slot machine by causing the CPU 71 to execute the game program and the game system program. Needless to say, the processor may alternatively store the game program and the game system program in the ROM 72 instead of the memory card 54.
The RAM 73 stores data and programs which are used in operation of the main CPU 71. For example, when the process of loading the aforementioned game program, game system program or authentication program is executed, the RAM 73 can store the program. The RAM 73 is provided with working areas used for operations in execution of these programs. Examples of the areas include: an area that stores counters for the number of games, the bet amount, the payout amount, the credit amount, the number of times of execution of free game counter, and the like; and an area that stores symbols (code numbers) randomly determined. The RAM 73 stores the symbol arrangements of the normal game video reels described above and the symbol arrangements of the free game video reels of the A type to the E type, and is equivalent to a video reel group storage. Furthermore, the RAM 73 stores the symbol combination table and the free game type table, and is equivalent to a table storage.
The communication interface 82 is for communicating with the external controller 200 such as a server, through the communication line 301. Further, the motherboard 70 is connected with a later-described door PCB (Printed Circuit Board) 90 and a main body PCB 110 by respective USBs. The motherboard 70 is also connected with a power supply unit 81. When the power is supplied from the power supply unit 81 to the motherboard 70, the main CPU 71 of the motherboard 70 is activated, and then the power is supplied to the gaming board 50 through the PCI bus so as to activate the CPU 51.
The door PCB 90 and the main body PCB 110 are connected with input devices such as a switch and a sensor, and peripheral devices the operations of which are controlled by the main CPU 71. The door PCB 90 is connected with a control panel 30, a reverter 91, a coin counter 92C and a cold cathode tube 93.
The control panel 30 includes: a change switch 31S, a cashout switch 32S, a help switch 33S, a 1-bet switch 34S, a 2-bet switch 35S, a 3-bet switch 37S, a 4-bet switch 38S, a 5-bet switch 39S, a play-10-lines switch 40S, a play-20-lines switch 41S, a play-30-lines switch 42S, a play-50-lines switch 43S, a gamble switch 44S, a max-bet switch 45S, and a spin switch 46S, which correspond to the above described buttons, respectively. Each of the switches outputs a signal to the main CPU 71 upon detection of the pressing of the button corresponding thereto by the player.
The coin counter 92C checks whether a coin inserted into the coin receiving slot 36 is genuine in terms of the material, shape, or the like. When determining that the coin is genuine, the coin counter 92C outputs a signal to the main CPU 71. Non-genuine coins are ejected through a coin payout exit 15A.
The reverter 91 operates based on a control signal output from the main CPU 71, and distributes valid coins validated by the coin counter 92C into a hopper 113 or a cash box (not illustrated). That is, coins are distributed into the hopper 113 when the hopper 113 is not filled with coins, while coins are distributed into the cash box when the hopper 113 is filled with coins.
The cold cathode tube 93 functions as a backlight installed on the rear face side of the upper image display panel 131 and the lower image display panel 141, and turns on based on a control signal outputted from the main CPU 71.
To the main body PCB 110 are connected the lamp 111, the speaker 112, a hopper 113, a coin detection unit 113S, the touch panel 114, the bill validator 115, a graphic board 130, a ticket printer 171, a card reader 172, a key switch 173S and the data display 174.
The lamp 111 turns on based on a control signal outputted from the main CPU 71. The speaker 112 outputs sounds 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 a designated number of coins from the coin payout exit 15A to the coin tray 18. The coin detection unit 113S outputs a signal to the main CPU 71 upon detection of coins paid out by the hopper 113.
The touch panel 114 detects a place on the lower image display panel 141 touched by the player's finger or the like, and outputs to the main CPU 71 a signal corresponding to the detected place. Upon acceptance of a valid bill, the bill validator 115 outputs to the main CPU 71 a signal corresponding to the face amount of the bill.
The graphic board 130 controls image display executed by the respective upper image display panel 131 and lower image display panel 141, based on a control signal outputted from the main CPU 71. The symbol display region 4 of the lower image display panel 141 displays the five video reels 3 by which the scrolling and stop motions of the symbol columns included in the respective video reels 3 are displayed. The graphic board 130 is provided with a VDP generating image data, a video RAM temporarily storing the image data generated by the VDP, and the like.
The graphic board 130 is provided with the VDP (Video Display Processor) generating image data based on a control signal outputted from the main CPU 71, the video RAM temporarily storing the image data generated by the VDP, and the like. It is to be noted that the image data used in generation of image data by the VDP is included in the game program that has been read from the memory card 54 and stored into the RAM 73.
Based on a control signal outputted from the main CPU 71, the ticket printer 171 prints on a ticket a barcode representing encoded data of the credit amount stored in the RAM 73, date and time, the identification number of the slot machine 1, and the like, and then outputs the ticket as the ticket 175 with a barcode.
The card reader 172 reads data stored in a card inserted into the card slot 176 and transmits the data to the main CPU 71, or writes data into the card based on a control signal outputted from the main CPU 71.
The key switch 173S is provided in the keypad 173, and outputs a predetermined signal to the main CPU 71 when the keypad 173 has been operated by the player.
The data display 174 displays data read by the card reader 172 and data inputted by the player through the keypad 173, based on a control signal outputted from the main CPU 71.
(Arrangement of Symbol Combination Table)
Now, symbol combination tables will be described with reference to
The symbol combination tables for the normal game and the free game define the combinations of symbols with which a winning (WIN) is achieved and payout amounts. In the slot machine 1, a win is achieved when the scroll of the symbol column of each video reel 3 is stopped and a combination of symbols displayed on an activated payline (see
Basically, in cases of “POSEIDON”, “DOLPHIN”, “TURTLE”, “SEAHORSE”, “SEASHELL”, “ACE”, “KING”, “QUEEN”, “JACK”, “TEN”, and “NINE” symbols, a win is established when three, four, or all of five symbols of the same type are displayed on a payline by the video reels 3. In cases of “POSEIDON”, “DOLPHIN”, “TURTLE”, “SEAHORSE”, and “SEASHELL” symbols, a win is established when two symbols of the same type are displayed on a payline by the video reels 3. The “WILD” symbol is able to substitute for POSEIDON”, “DOLPHIN”, “TURTLE”, “SEAHORSE”, “SEASHELL”, “ACE”, “KING”, “QUEEN”, “JACK”, “TEN”, and “NINE” symbols.
For example, in the normal game and the free game, when five “POSEIDON” symbols are displayed on a payline of the symbol display region 4 by all video reels 3, it is determined that the payout amount is “100”. Based on the determined payout amount, coins are paid out. The payout of the coins is done by actually ejecting coins through the coin payout exit 15A, making addition to the credit amount, or issuing a ticket with a barcode.
The “FEATURE” symbol is a scatter symbol triggering the free game. To be more specific, when three “FEATURE” symbols are displayed in the symbol display region 4, “2” is selected as a payout amount of scatter payment. Then the free game starts at the next game. When three “FEATURE” symbols are displayed in the symbol display region 4 in the free game (awarding of the right to execute the free game), a predetermined number of times of execution of the free game is further awarded as a benefit.
(Free Game Type Table)
Now, a free game type table will be described with reference to
As shown in
To be more specific, when the video reels of the A type are selected in a later-described free game video reel type selection process, the payout rate is 1 and a payout at the time of a winning in the free game is set at a value calculated by multiplying the payout defined in the symbol combination table by 1, and hence the free game becomes executable for 20 times. (In this case, the number of times of execution of the free game added at the time of the re-trigger in the free game is also 20).
When the video reels of the B type are selected in the later-described free game video reel type selection process, the payout rate is 2 and a payout at the time of a winning in the free game is set at a value calculated by multi the payout defined in the symbol combination table by 2, and the free game becomes executable for 12 times (In this case, the number of times of execution of the free game added at the time of the re-trigger in the free game is also 12).
In this regard, assume that the value calculated by multiplying the payout defined in the symbol combination table by 2 is set as a payout at the time of a winning in the free game. If, for example, two “POSEIDON” symbols are arranged on a payline, the payout in the free game is 2×2=4 with reference to the symbol combination table shown in
Furthermore, when the video reels of the C type are selected in the later-described free game video reel type selection process, the payout rate is 3 and a payout at the time of a winning in the free game is set at a value calculated by multiplying the payout defined in the symbol combination table by 3, and hence the free game becomes executable for 8 times. (In this case, the number of times of execution of the free game added at the time of the re-trigger in the free game is also 8).
When the video reels of the D type are selected in the later-described free game video reel type selection process, the payout rate is 4 and a payout at the time of a winning in the free game is set at a value calculated by multiplying the payout defined in the symbol combination table by 4, and the free game becomes executable for 6 times. (In this case, the number of times of execution of the free game added at the time of the re-trigger in the free game is also 6).
When the video reels of the E type are selected in the later-described free game video reel type selection process, the payout rate is 5 and a payout at the time of a winning in the free game is set at a value calculated by multiplying the payout defined in the symbol combination table by 5, and the free game becomes executable for 5 times. (In this case, the number of times of execution of the free game added at the time of the re-trigger in the free game is also 5).
The free game type table defines that, the higher the payout rate is with respect to the payout defined in the symbol combination table shown in
On this account, when, for example, the free game is executed with the video reels of the type with a high payout (payout rate), the number of times of execution of the free game is small. To put it differently, the player is able to enjoy the free game with a high payout in a short time.
In the meanwhile, when the free game is executed with the video reels of the type with a low payout (payout rate), the number of times of execution of the free game is large. To put it differently, the player is able to enjoy the free game for a relatively long time with a low payout.
Because the symbols are arranged so that the overall expectation of the payout after the free game is executed for the executable number of times remains the same whichever one of the A type to the E type of the video reels is used, the player can enjoy the free game in various modes with different payout amounts and different numbers of times of execution of the free game, while the fairness of the payout in the free game is maintained. To be more specific, the symbols arranged on the video reels of the A type to the E type are determined by changing the type, the number, the total number, and the locations of the symbols so that the following expected total amounts are identical with one another: expected total amount of payouts awarded when the free game is executed for 20 times at the payout rate of 1 by using the video reels of the A type; the expected total amount of the payouts awarded when the free game is executed for 12 times at the payout rate of 2 by using the video reels of the B type; the expected total amount of the payouts awarded when the free game is executed for 8 times at the payout rate of 3 by using the video reels of the C type; the expected total amount of the payouts awarded when the free game is executed for 6 times at the payout rate of 4 by using the video reels of the D type; and the expected total amount of the payouts awarded when the free game is executed for 5 times at the payout rate of 5 by using the video reels of the E type. The awarded number of times of execution of the free game and the payout rate are changeable no matter which one of the A type to the E type is used as the video reels, on condition that the overall expectation of the payout when the free game is executed for the executable number of times remains the same.
While in the arrangement above the A type to the E type are associated with the payout rates, the payout amounts in the free game may be directly associated with the A type to the E type.
[Contents of Program]
Now, the program to be executed by the slot machine 1 is described with reference to
(Main Control Process)
First, with reference to
First, when the slot machine 1 is powered on, the main CPU 71 reads the authenticated game program and game system program from the memory card 54 through the gaming board 50, and writes the programs into the RAM 73 (S11).
Next, the main CPU 71 executes at-one-game-end initialization process (S12). For example, data that becomes unnecessary after each game in the working areas of the RAM 73, such as the bet amount and the symbols randomly determined, is cleared.
The main CPU 71 executes a coin-insertion/start-check process which is described later with reference to
The main CPU 71 then executes a symbol random determination process (S14). In the process, to-be stopped symbol is determined based on the random numbers for symbol determination.
Specifically, the main CPU 71 first samples random numbers for symbol determination. The main CPU 71 then randomly determines to-be stopped symbol for the video reels 3. The main CPU 71 executes random determination for each of the video reels 3, and determines any one of the symbols as the to-be stopped symbol. The probabilities of the respective symbols being determined are basically equal. The main CPU 71 stores the determined to-be stopped symbol of each video reel 3 in a symbol storing area in the RAM 73.
The main CPU 71 then executes an effect contents determination process (S15). The main CPU 71 samples an effect-use random number, and randomly selects any of the effect contents from the preset plurality of effect contents.
Next, the main CPU 71 executes the symbol display control process (S16). In the process, the scroll of the symbol column of each video reel 3 is started, and the to-be stopped symbol determined in the symbol random determination process of S14 is stopped at a predetermined position (e.g. the upper area in the symbol display region 4). That is, 20 symbols including the to-be stopped symbol are displayed in the symbol display region 4. For example, when the to-be stopped symbol is the symbol with the code number “10” and this symbol is displayed in the upper stage, the symbols with the code numbers “11”, “12”, and “13” are displayed in the upper middle stage, the lower middle stage, and the lower stage of the symbol display region 4, respectively.
The main CPU 71 then executes a payout determination process (S17). In this process, the symbol combination table (see
Next, the main CPU 71 determines whether or not a free game trigger is met (S18). In the present embodiment, the shifting to the free game is triggered when three “FEATURE” symbols are displayed in the symbol display region 4. When the free game trigger has been met (S18: YES), the main CPU 71 executes the later-described free game process (S19).
Thereafter, after the step S19 or when it is determined in the step S18 that the free game trigger is not established (S18: NO), the main CPU 71 determines whether there is a payout (S20). That is to say, whether a payout has been awarded in S17 or S19 is determined. When there is a payout (S20: YES), a payout process is executed (step S21). The main CPU 71 adds the value stored in the payout amount storage area to the value stored in the credit amount storage area provided in the RAM 73. Alternatively, the hopper 113 may be driven based on an input to the collect switch 32S, and coins are discharged to the coin tray 15 according to the value stored in the payout amount storage area. After this process or when it is determined in S20 that there is no payout (S20: NO), the process proceeds to the step S12.
(Coin-Insertion/Start-Check Process)
Next, with reference to
First, the main CPU 71 determines whether or not insertion of a coin has been detected by the coin counter 92C (S41). When determining that the insertion of a coin has been detected, the main CPU 71 makes addition to the value stored in the credit amount storage area (S42). It is to be noted that the main CPU 71 may determine whether or not insertion of a bill has been detected by the bill entry 115, and when determining that the insertion of a bill has been detected, the main CPU 71 may add a value according to the bill to the value stored in the credit amount storage area.
After S42 or when determining in S41 that the insertion of a coin has not been detected, the main CPU 71 determines whether or not the value stored in the credit amount storage area is zero (S43).
When the main CPU 71 determines that the value stored in the credit amount storage area is not zero, the main CPU 71 permits operation acceptance of the bet buttons (1-bet button 34, 2-bet button 35, 3-bet button 37, 4-bet button 38, 5-bet button 39, and max bet button 45) (S44). Note that, in S44, an operation of the payline button (play-10-lines button 40, play-20-lines button 41, play-30-lines button 42, and play-50-lines button 43) is enabled. Operation of the payline button enables activation of a desirable number of paylines (see
Next, the main CPU 71 determines whether or not operation of any of the BET buttons has been detected (S45). When the main CPU 71 determines that the bet switch (1-bet switch 34S, 2-bet switch 35S, 3-bet switch 37S, 4-bet switch 38S, 5-bet switch 39S, and max-bet switch 45S) has detected the pressing of the BET button by the player, the main CPU 71 makes addition to a value stored in a bet amount storage area provided in the RAM 73 and makes subtraction from the value stored in the credit amount storage area, based on the type of the bet button and the type of the payline button (S46).
The main CPU 71 then determines whether or not the value stored in the bet amount storage area is at its maximum (S47). The main CPU 71, when determining that the value stored in the bet amount storage area is the maximum value, prohibits updating of the value stored in the bet amount storage area (S48). After S48 or when determining in S47 that the value stored in the bet amount storage area is not at its maximum, the main CPU 71 permits operation acceptance of the spin button 46 (S49).
After S49, when determining in S45 that the operation of any of the BET buttons has not been detected, or when determining in S43 that the value stored in the credit amount storage area is zero, the main CPU 71 determines whether or not operation of the spin button 46 has been detected (S50). The main CPU 71 shifts the process to S41, when determining that no operation of the spin button 46 is detected.
When the main CPU 71 determines that the operation of the spin button 46 has been detected, the coin-insertion/start-check process is ended.
(Free Game Process)
Now, referring to
Subsequently, the main CPU 71 executes a free game video reel type selection process (step S 101).
In this free game video reel type selection process, to begin with, as shown in
Subsequently, as shown in
In doing so, as shown in
While in the free game video reel type selection process above the player is encouraged to select one of the options A to E and determine the video reel used in the free game, the video reel used in the free game may be automatically selected from the video reels of the A to E types, when the trigger of the free game is established. The shifting from the normal game to the free game is smoothly done in this case, because the selection by the player is omitted. This allows the player to enjoy the random determination of the payout rate of the payout and the number of times of execution of the free game.
Thereafter, the number of times of execution of the free game corresponding to the type of the video reels corresponding to the option selected in S101 is added to the number of times of execution of free game counter and stored (S102). For example, when, as shown in
In addition to the above, the payout rate is set at a rate corresponding to the type of the video reels corresponding to the option selected in S101(S102). For example, when, as shown in
When three “POSEIDON” symbols are arranged on a payline, the payout in the free game is set at 10×5=50. When four “POSEIDON” symbols are arranged on a payline, the payout in the free game is set at 20×5=100. When five “POSEIDON” symbols are arranged on a payline, the payout in the free game is set at 100×5=500.
Next, the main CPU 71 executes the at-one-game-end initialization process (S103) in the same manner as in the step S12. Subsequently, the main CPU 71 performs the symbol random determination process in the same manner as in S14, based on the video reel for the free game selected in S101 (step S104). The main CPU 71 then executes the effect contents determination process (S105) in the same manner as in the step S15. Next, the main CPU 71 executes the symbol display control process (S106) in the same manner as in the step S16. The main CPU 71 then executes the payout determination process (S107) in the same manner as in the step S17.
Next, the main CPU 71 determines whether or not a re-trigger is established (S108). The re-trigger in the present embodiment is arrangement of three “FEATURE” symbols in the symbol display region 4 during the free game. When determines that the re-trigger is established (S108: YES), the main CPU 71 adds the number of times of execution of the free game, which is added at the time of the re-trigger corresponding to the type of the video reels corresponding to the option selected in S101, to the number of times of execution of free game counter, and stores the resulting number of times (S109). For example, when, as shown in
Subsequently, when the main CPU 71 has determined that that the re-trigger is not established (S108: NO) or after S109, the main CPU 71 executes a payout process (step S110). In this payout process, the main CPU 71 adds the value stored in a payout counter in the above-described payout determination process in the step S107 to the value stored in a free game payout counter. The free game payout counter is an area where the total payout amount determined during the free game is stored. When the free game process ends, the main CPU 71 adds, in the payout process in the step S21, the value stored in the free game payout counter to a credit amount counter provided in the RAM 73. In other words, the total payout amount determined in the free game is awarded at once. The payout may be awarded by ejecting coins from the coin payout exit 15A or by issuing a ticket with a barcode.
Subsequently, the main CPU 71 subtracts 1 from the number of times of execution of free game stored in the number of times of execution of free game counter (step S111). The main CPU 71 then determines whether the number of times of execution of free game stored in the counter is 0 (step S112). When determining that the number of times of execution of free game stored in the counter is not 0, the main CPU 71 proceeds to the step S103.
In the meanwhile, when the number of times of execution of free game counter is 0 (S112: YES), the free game process is terminated. When the free game process is terminated, the processing proceeds to the step S20 having been described with reference to
[Image Display]
Now, image display by the slot machine 1 will be described with reference to
To begin with, image display in the normal game will be described with reference to
As shown in
On the lower image display panel 141 in the normal game, in addition to the above-described symbol display region 4, a credit meter 404, a bet meter 405, a win meter 406, a bet information and game state display region 407, a payline number display region 408, a help touch button 409, a language switching touch button 410, a sound volume switching touch button 411, and a denomination display region 412. In the credit meter 404 is displayed a remaining credit amount. The default value is 0. In other words, a credit amount stored in the RAM 73 is displayed. The bet meter 405 displays the total bet amount of the current game (or the final game). The win meter 406 displays the total credit amount of WIN and the detail of the WIN. The win credit amount displayed in the win meter 406 is always an actual obtained credit amount after the multiplication by the bet per line.
In the bet information and game state display region 407 is displayed bet information of the current game (or the final game). In the first line is displayed an amount of bet per line. The image display is in the singular form or plural form in accordance with the bet amount. For example, when the amount of bet per line is “1”, the region displays “1 CREDIT PER LINE” and “CREDIT” is displayed in the singular form. When the amount of bet per line is “2”, the region displays “2 CREDITS PER LINE” and “CREDITS” is displayed in the plural form. The plural form “CREDITS” is displayed when the amount of bet per line is “3” or more, too. The bet information and game state display region 407 further displays the current game state. The region is not displayed when the current game state is game in progress. When the current game state is game over, “GAME OVER” is displayed. When the current game state is waiting for GAMBLE, “PLAY ON, GAMBLE or TAKE WIN” is displayed.
In the payline number display region 408 are displayed payline number of 50 paylines (see
When the player touches the help touch button 409, the first page of the help screen is displayed on the lower image display panel 141. The help touch button 409 is darkened when it is invalidated, e.g., during the rotation of the video reels 3.
As the language switching touch button 410 is touched by the player, the language is switched to English or Chinese. The language switching touch button 410 is activated only during the advertisement, and is darkened when it is invalidated, e.g., during the rotation of the video reels 3. Furthermore, on the language switching touch button 410, the displayed national flags are changed to “U.K./China” or “U.S.A./China” in accordance with the setting of the AUDIT. When the language switching is set at “DISABLE”, the language switching touch button 410 is changed to a paytable button with which a payout table is displayed on the help screen.
The sound volume switching touch button 411 is used for switching the game sound volume at three stages. Each time the button is touched by the player, the game sound volume is switched such that, for example, from low to middle to high to small to middle. The denomination display region 412 displays current denomination.
<Help Screen Display>
Now, image display in the normal state will be described with reference to
As the lower image display panel 141 shown in
When the player touches the EXIT touch button 414, the help screen 413 disappears from the lower image display panel 141 and a normal game screen (see
[Win Effect]
Now, an win effect in the slot machine 1 will be described with reference to
The win effect is an effect executed when a win is achieved in the normal game or the free game. That is to say, this effect is executed when a combination of symbols displayed on an activated payline is identical with a combination of symbols defined in the symbol combination table shown in
<Flow of Win Effect>
Now, the flow of the win effect will be described with reference to
To begin with, as shown in
On the lower image display panel 141, the win effect is performed for the achieved win. The win effect is performed for the payment as a result of the arrangement of three “FEATURE” symbols in the symbol display region 4, and is then performed for the paylines one by one in ascending order of payline numbers. In this regard, for symbols for each of which a win animation is prepared, an animation effect is carried out regardless of the payline number. In the meanwhile, each symbol for which no win animation is prepared (i.e., symbols with a blinking win effect) blinks only when a win is achieved by a combination of symbols including that symbol.
On the win meter 406 of the lower image display panel 141, the total win at the start of the increment in the upper stage is displayed. In the lower stage which displays the details, the payout of the win line currently turned on (LINE 10 WIN=50 in
Subsequently, as shown in
On the win meter 406 of the lower image display panel 141, the increment display of the total win is continued in the upper stage. In the lower stage displaying details, the payout of the win line currently turned on (LINE 26 WIN=15 in
Subsequently, as shown in
On the lower image display panel 141, the display of the win line proceeds to next. In this case, the display of the win line proceeds from the black circle symbols to the “J” symbols. Because win animations are prepared for both the star symbols and the black circle symbols, animation effects are performed irrespective of the line numbers. In the meanwhile, the “J” symbols blink because the time to display the win line has come but no win animation is prepared therefor.
On the win meter 406 of the lower image display panel 141, the increment display of the total win is continued in the upper stage. In the lower stage where details are displayed, the payout of the win line which is currently turned on (LINE 39 WIN=5 in
Subsequently, as shown in
On the win meter 406 of the lower image display panel 141, the increment display of the total win is terminated in the upper stage. The total win is displayed also in the upper stage. In the lower stage displaying details, as all of the winning symbols are displayed for once, the symbols are again displayed in a looped manner in an ascending order of line numbers. In
Thereafter, the display state shifts from

On the other hand, when the increment amount becomes more than 50 times as much as the bet amount, the first gold signboard 421 shown in (b) in
<Effect Sound when Three “FEATURE” Symbols Appear>
Now, effect sound when three “FEATURE” symbols appear will be described with reference to
When three “FEATURE” symbols appear in the symbol display region 4, dedicated bleep sound is reproduced. The sound reproduction starts when all reels stop, and lasts three seconds until the increment starts after 30 frames elapse. During the reproduction of the bleep sound, the symbol animation, the display of the LINE WIN, and the increment display are not performed.
According to the embodiment of the present invention, as shown in
After the three seconds, as shown in
<Total Win Signboard After Free Game>
Now, the total win signboard after the free game will be described with reference to
After the end of the free game, a total obtained credit is displayed on the lower image display panel 141. In accordance with the obtained credit amount (i.e., how many times as much as the total bet), one of three types of effects is used.
When the total obtained credit is less than 20 times as much as the total bet, the silver signboard 421 shown in (a) in
[Free Game Effects]

[Win Meter Information Display]
Now, win meter information display of the slot machine 1 will be described with reference to
As shown in
The win total amount display region 406 displays a win credit and a money amount. Increment display is performed based on a win increment speed sheet, when performed. More specifically, the win total amount display region 406A displays a credit amount obtained in the current game cycle (or in the previous game cycle). When a credit is obtained more than once in one game cycle, the credit is added each time it is obtained. For example, when the free game is triggered in the normal game and the player obtains LINE WIN 20 and SCATTER WIN 100, the image display is incremented from “0” to “120”. Thereafter, when a payout amount of 200 is obtained in the free game, the increment display is conducted from 120 to 320. 0 is displayed either when the next game cycle starts or when lost in GAMBLE. In the meanwhile, when a win is achieved in GAMBLE, no increment is carried out and the displayed amount is immediately doubled.
The detail display region 406 relates to a win in the normal game and the free game. After the fifth reel stops, the number of the win line and the win credit are displayed. When more than one line payout simultaneously occurs, the line payouts are displayed one by one at intervals of 0.5 second. The payouts are serially displayed from the one having the smallest payline number, and the one having the smallest number is displayed again after the one having the largest payline number is displayed. In other words, the detail display region 406 displays the details of the credit obtained by the spinning in this time. When there are plural elements (e.g., another line or scatter), the elements are switched at intervals of 0.5 second. The order of switching of image display is from scatter payout to normal payout (from the smallest payline number to the largest payline number).
The total display region 406C displays the total credits of the detail display region 406 when the increment in the win total amount display region 406A is completed. The region is not displayed until the increment in the win total amount display region 406A is completed. In other words, the total display region 406C displays the total credits obtained in the spinning in this time. In this regard, the total credits are displayed after the increment in the win total amount display region 406A is finished.
