DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiment 1

It will be described an embodiment 1 of a slot machine and a playing method thereof according to the invention.

As shown in FIG. 1, a slot machine executes a playing method comprising steps of receiving a selection signal from an exterior, setting, among plural types of selection object symbols 181, at least one of the selection object symbols 181 having a type corresponding to the selection signal as a scatter symbol 182, setting payout rankings for the scatter symbols 182 set, based on payout ranking signals inputted from the exterior, rearranging plural symbols 180 including the scatter symbols 182 in a display unit 101, awarding a payout determined by a combination of the symbols 180 rearranged on a payline L and awarding a payout determined on the basis of the scatter symbols 182 rearranged on and out of the payline L and the payout rankings.

Further, the slot machine 10 executes a playing method comprising a step of providing an arrangement area (display windows 151˜155) for arranging the plural symbols 180 and a selection area (selection windows 161, 162, 163) for displaying the selection object symbols 181 to different parts of the display unit 101.

Herein, the “arrangement” means a state in which the symbols 180 including the scatter symbols 182 are allowed to be visible with naked eyes of an exterior player. In other words, in FIG. 1, the symbols 180 are under state of being displayed in the display windows 151˜155. In the mean time, the “rearrangement” is meant by arranging the symbols 180 again after dismissing the arrangement of the symbols 180.

The “payout ranking” is meant by a size of a payout corresponding to the symbol 180. Specifically, referring to a relationship of “BELL” and “CHERRY,” when a payout ranking of “BELL” is higher than that of “CHERRY,” more payouts are paid out for “BELL” than for “CHERRY.” In addition, the “payline” L is provided to determine a combination of the symbols 180. In other words, when the symbols 180 are rearranged on and out of the payline L, a combination is determined for only the symbols 180 rearranged on the pay line. As a result of the determination for a combination, when it is made a winning combination, it is carried out, for example, a process of paying out a coin in accordance with the winning combination.

In addition, the “scatter symbol” 182 is a symbol making it a condition that a winning is made through only the rearrangement thereof, irrespective of the payline L. In other words, when the scatter symbol 182 is rearranged, a winning is made and it is carried out, for example, a process of paying out a coin on the basis of the number of all the scatter symbols 182 rearranged on and out of the payline L. Furthermore, the 'symbol” is meant by all symbols used in the slot machine 10 and includes the scatter symbols 182 and the selection object symbols 181. The payline L, the symbol 180, the scatter symbol 182 and the winning combination will be more specifically described later.

(Display Unit 101)

As shown in FIG. 2, the slot machine executing the above playing method is provided with a display unit 101 (display) and a game controller 100. The display unit 101 is structured to have the payline L and to arrange the plural symbols including the scatter symbols.

The display unit 101 may be a mechanical structure with a reel device for arranging the symbols by rotation of a reel or electrical structure with a video reel on which an image is displayed for arranging the symbols. Further, the display unit 101 may be a structure of combining a mechanical structure (reel) and an electrical structure (video reel). The electrical structure may include a liquid crystal device, a CRT (cathode-ray tube), a plasma display and the like. A detailed structure of the display unit 101 will be described later.

(Game Controller 100)

The game controller 100 has plural types of selection object symbols and is also structured to execute a first process of setting at least one of the selection object symbols having a type corresponding to a selection signal inputted from an exterior, as a scatter symbol, a second process of setting payout rankings for the scatter symbols set, based on payout ranking signals inputted from the exterior, a third process of rearranging the symbols to award a payout determined by a combination of symbols rearranged on the payline and a fourth process of awarding a payout determined on the basis of the scatter symbols rearranged on and out of the payline L and the payout rankings. In other words, the game controller 100 has the plural types of selection object symbols and also comprises a first processing unit, a second processing unit, a third processing unit and a fourth processing unit. Herein, the “selection object symbol” is a symbol which will be set as a scatter symbol by player's selection.

Further, the game controller 100 is also structured to execute a fifth process of providing an arrangement area for arranging the plural symbols and a selection area for displaying the selection object symbols to different parts of the display unit 101. In other words, the game controller 100 comprises a fifth processing unit in addition to the first to fourth processing units.

The game controller 100 comprises a selection object symbol memory 105 for storing the plural types of selection object symbols, a scatter symbol memory 106 for storing a selection object symbol selected by a player as a scatter symbol, a symbol memory 108 for storing all symbols including the scatter symbol and a display symbol memory 107 for storing the symbols in the respective memories 105, 106, 108 as a display symbol. The display symbol memory 107 can be accessed by a display control unit 102. The display control unit 102 sets the arrangement area for arranging the plural symbols and the selection area for displaying the selection object symbols to the different parts of the display unit 101. In addition, the display control unit 102 reads out the symbol in the display symbol memory 107 under control of a game executing unit 110 and displays the plural symbols in the arrangement areas and the selection object symbols in the selection area. A detailed display state will be described later.

In addition, the game controller 100 comprises a symbol selecting unit 104 for specifying the selection object symbol having a type corresponding to the selection signal and setting the specified selection object symbol as a scatter symbol. The symbol selecting unit 104 receives the selection signal from an exterior input unit 103. The exterior input unit 103 is separately provided from the game controller 100 and receives the selection signal which is inputted by a player from the exterior. Meanwhile, the exterior input unit 103 may be a touch panel provided to the display unit 101, or a mouse or selection button.

Further, the game controller 100 is connected to a game start unit 109. The game start unit 109 has a function of outputting a game start signal in accordance with control of the player. The game controller 100 comprises a game executing unit 110 for rearranging the symbols with an input of a game start signal, as trigger, from the game start unit 109, a combination payout determining unit 111 for determining a payout determined by a combination of the symbols rearranged on the payline in a unit game, a scatter symbol payout determining unit 112 for determining a payout determined on the basis of the scatter symbols rearranged on and out of the payline and the payout rankings, and a payout award unit 113 for awarding the respective payouts determined in the combination payout determining unit 111 and the scatter symbol payout determining unit 112.

Further, the game controller 100 comprises a payout ranking selecting unit 117 to which a payout ranking signal is inputted from the exterior input unit 103. The payout ranking selecting unit 117 sets a payout ranking for the scatter symbol, which is stored in the scatter symbol memory 106, based on the payout ranking signal. The payout ranking selecting unit 117 stores the scatter symbol and the payout ranking corresponding to the scatter symbol in a payout ranking memory 118. The payout ranking memory 118 can be accessed by the scatter symbol payout determining unit 112.

In the mean time, each block of the game controller 100 may be structured with a hardware or software, as required.

(Operation of Game Controller 100)

In the above structure, an operation of the game controller 100 is described. First, the selection object symbols in the selection object symbol memory 105 are displayed in the display unit 101 by the display symbol memory 107 and the display control unit 102. Thereby, a player can select a desired scatter symbol among the selection object symbols displayed in the display unit 101.

Furthermore, in the display unit 101, the plural symbols are displayed in the arrangement area and the selection object symbols are displayed in the selection area. In other words, the game controller 100 executes the fifth process of providing the arrangement area for arranging the plural symbols and the selection area for displaying the selection object symbols to different parts of the display unit 101. Thereby, the player can easily recognize the selection object symbols because the selection object symbols are displayed in the selection area separately from the arrangement area.

Next, it is received a selection signal which is inputted by the player using the exterior input unit 103. The selection signal inputted from the exterior input unit 103 is contrasted with the types of the selection object symbols in the symbol selecting unit 104, so that it is selected a selection object symbol having a type corresponding to the selection signal. The selection object symbol selected is stored in the scatter symbol memory 106. Thereby, the game controller 100 executes the first process of setting at least one of the selection object symbols having a type corresponding to the selection signal inputted from an exterior, as a scatter symbol.

Next, it is received a payout ranking signal which is inputted by the player using the exterior input unit 103. The payout ranking signal is contrasted with the types of the scatter symbols in the payout ranking selecting unit 117, so that it is set a payout ranking of the payout ranking signal for the scatter symbol contrasted. Then, the payout ranking and the scatter symbol are stored in the payout ranking memory 118. Thereby, the game controller 100 executes the second process of setting payout rankings for the scatter symbols set, based on payout ranking signals inputted from the exterior. [0045]The scatter symbol in the scatter symbol memory 106 is stored in the display symbol memory 107. In the mean time, the symbol in the symbol memory 108 is stored in the display symbol memory 107. The symbols including the scatter symbol in the display symbol memory 107 can be displayed in the display unit 101 by the display control unit 102. Then, when the game executing unit 110 executes a unit game, symbols relating to the unit game are displayed in the display unit 101, so that the symbols are rearranged.

Then, a payout, which is determined by a combination of the symbols rearranged on the payline, is awarded by the scatter symbol payout determining unit 112 and the payout award unit 113. In the mean time, a payout, which is determined on the basis of the scatter symbols rearranged on and out of the payline L and the payout rankings, is awarded by the combination payout determining unit 111 and the payout award unit 113. Thereby, the game controller 100 executes the third process of rearranging the symbols to award a payout determined by a combination of symbols rearranged on the payline and the fourth process of awarding a payout determined on the basis of the scatter symbols rearranged on and out of the payline and the payout rankings.

As can be clearly seen from the above operation, the slot machine 10 embodies, as also shown in FIG. 1, the playing method of receiving a selection signal from an exterior, setting, among plural types of selection object symbols 181, at least one of the selection object symbols 181 having a type corresponding to the selection signal as scatter symbols 182, setting payout rankings for the scatter symbols 182 set, based on payout ranking signals inputted from the exterior, rearranging plural symbols 180 including the scatter symbols 182 in the display unit 101, awarding a payout determined by a combination of the symbols 180 rearranged on the payline L and awarding a payout determined on the basis of the scatter symbols 182 rearranged on and out of the payline L and the payout rankings. Further, the slot machine 10 embodies the playing method of providing an arrangement area for arranging the plural symbols and a selection area for displaying selection object symbols to different parts of the display unit 101.

(Display State)

It will be specifically described an example of a display state of the display unit 101, with respect to the operation processes of the slot machine 10 and the playing method. In the mean time, as shown in FIGS. 3 to 7, the display state is described with reference to a structure in which the display unit 101 arranges the symbols in a video reel manner and a touch panel 69 (exterior input unit 103) is provided to a display surface of the display unit 101.

The display unit 101 has display windows 151˜155 as the arrangement area for arranging the plural symbols. The display windows 151˜155 are arranged in a central part of the display unit 101. In the display windows 151˜155, columns of symbols consisting of the plural symbols 180 are scroll-displayed. In addition, each of the display windows 151˜155 is divided into upper, center and lower stages 151a, 151b, 151c. Each of the symbols is stopped (arranged) in the respective stages 151a, 151b, 151c. For example, in FIG. 3, “ORANGE” is stopped in the upper stage 151a of the display window 151, “STRAWBERRY” is stopped in the center stage 151b of the display window 151 and “BLUE 7” is stopped in the lower stage 151c of the display window 151. As a result, the display windows 151˜155 display a symbol matrix consisting of 5 columns and 3 rows. In the mean time, the symbol matrix is not limited to 5 columns/3 rows.

In addition, the display unit 101 has three selection windows 161, 162, 163 as the selection area for displaying the selection object symbols 181. The selection windows 161, 162, 163 are arranged in a right-handed upper part of the display unit 101 so as not to overlap with the display windows 151˜155. “BELL,” “CHERRY” and “ORANGE,” which are the selection object symbols 181, are displayed in the selection windows 161, 162, 163, respectively. Further, a selection object window 165 is provided below the selection windows 161, 162, 163. The selection object window 165 displays symbols which are candidates of the selection object symbols 181. The selection object window 165 enables a player to intuitively recognize that the selection object symbols 181 are selected among the candidate symbols displayed in the selection object window 165 and then displayed in the selection windows 161, 162, 163.

In the mean time, the number of the selection windows 161, 162, 163 is not limited to three and may be plural. Further, the selection windows 161, 162, 163 may be provided to an arbitrary position on condition that they can avoid the overlapping with the display windows 151˜155.

In addition, the display unit 101 has two scatter symbol display units 171. The scatter symbol display units 171 have a basket shape, and display the scatter symbols 182 as a received thing, as shown in FIG. 4. The scatter symbol display units 171 are provided to a left-handed upper corner part of the display unit 101. In the mean time, the scatter symbol display units 171 may be provided to an arbitrary position on condition that they can avoid the overlapping with the display windows 151˜155 and the selection windows 161, 162, 163.

In the display unit 101 structured as described above, the display state of FIG. 3 shows a state allowing the scatter symbols 182 to be selected among the selection object symbols 181. In other words, after the symbols 180 are rearranged in the display windows 151˜155, it is made a display state shown in FIG. 3 at the time when a next game is started. A received thing is not shown in the scatter symbol display units 171. In addition, as a result of the lottery among the candidates of the selection object window 165, “BELL,” “CHERRY” and “ORANGE” are respectively displayed in the selection windows 161, 162, 163, as the selection object symbols 181. Meanwhile, the display unit 101 may display a character, change of background color or emphasis for urging the player to select the scatter symbol 182.

Thereby, the player can intuitively recognize that the player can select the scatter symbol 182 among the selection object symbols 181 by observing a state in which the received state is not displayed in the scatter symbol display units 171 and a state in which the selection object symbols 181 are displayed in the selection windows 161, 162, 163, with naked eyes.

A display state of FIG. 4 shows a state of selecting the scatter symbols 182. Specifically, when the player pushes “BELL” of the selection object symbols 181 with a hand 190, the touch panel 69 produces a selection signal indicating position information of “BELL.” Then, “BELL,” which is specified on the basis of the selection signal, is moved to any one of the scatter symbol display units 171 while changing its size, and is then received in the scatter symbol display unit 171. Thereby, the player can intuitively recognize that “BELL” has been set as the scatter symbol 182, by observing the successive movements of the selection object symbol 181 with naked eyes.

In addition, at this time, the other scatter symbol display unit 171 is empty. Accordingly, the player can continue to intuitively recognize that the player can select the remaining selection object symbols 181 displayed in the selection windows 161, 162, 163 as the scatter symbol 182. After that, when the player pushes “CHERRY” of the selection object symbols 181, “CHERRY” is moved to the other scatter symbol display unit 171 while changing its size, and is then received in the other scatter symbol display unit 171.

A display state of FIG. 5 shows a state after selecting the two scatter symbols 182. Specifically, “BELL” and “CHERRY” are displayed in the scatter symbol display units 171, as a received thing. In addition, the selection object symbols 181 disappear from the selection windows 161, 162, 163. As a result, the player can intuitively recognize that the process of receiving the selection of the scatter symbol 182 has been completed, by observing the state in which nothing is displayed in the selection windows 161, 162, 163, with naked eyes.

A display state of FIG. 6 shows a state of setting payout rankings for the scatter symbols 182, 182. In other words, “BELL” and “CHERRY” are displayed as a received thing, with respect to the scatter symbols 182, 182. In this case, when the player pushes the scatter symbol display unit 171 in which “CHERRY” is received, for example, the scatter symbol display unit 171 is enlarged. Thereby, the player can intuitively recognize that the payout ranking of “CHERRY” becomes higher. In the mean time, when the player then pushes the scatter symbol display unit 171 in which “BELL” is received, the pushed scatter symbol display unit 171 is enlarged and the other scatter symbol display unit 171 is downscaled.

A display state of FIG. 7 shows a state in which a unit game is started. Specifically, the symbols 180 of the display windows 151˜155 are scroll-displayed. A display state of FIG. 8 shows a state in which the unit game has been completed. In other words, the symbols 180 of the display windows 151˜155 are rearranged.

(Symbol, Combination, etc.)

As shown in FIG. 9, the symbols 180 to be displayed in the display windows 151˜155 of the display unit 101 constitute columns of symbols, each of which having 22 symbols. The symbols constituting the respective columns of symbols are given with one code number of 0˜21. Each of the columns of symbols is constituted with a combination of symbols of “JACKPOT 7,” “BLUE 7,” “BELL,” “CHERRY,” “STRAWBERRY,” “PLUM,” “ORANGE” and “APPLE.”

The three successive symbols in the columns of symbols are displayed (arranged) in the upper, center and lower stages 151a, 151b, 151c of the display windows 151˜155, respectively, so that they constitute a symbol matrix of 5 colums/3 rows. When a 1-BET button 26 or MAX-BET button 27 is pushed and then a spin button 23 is pushed, the symbols constituting the symbol matrix start the scroll. When the scroll starts, the scrolls of the respective symbols are stopped (rearranged) after a predetermined time period has lapsed.

In addition, various winning combinations are predetermined with regard to the respective symbols. The winning combination is a combination that a combination of symbols stopped on the payline L becomes an advantageous state to the player. The advantageous state is a state in which a coin is paid out in accordance with the winning combination, a state in which the payout-number of coins is added to a credit, a state in which a bonus game is started, and the like.

Specifically, when a combination of “APPLE” symbol is stopped on the payline L, a bonus is triggered and a gaming state is shifted to a bonus game from a basic game. In addition, when a symbol of “CHERRY” is stopped on the payline L, 20 coins (game medium) are paid out per one bet. When a symbol of “PLUM” is stopped on the payline L, 5 coins are paid out per one bet.

In the mean time, a bonus game is a gaming state that is more advantageous than a basic game. In one embodiment, the bonus game is a free game. The free game is a gaming state allowing a player to play a game for a predetermined number of times, without betting a coin. The bonus game is not particularly limited as long as it is a gaming state advantageous to the player, i.e., it is more advantageous than the basic game. For example, the bonus game may include a state in which it is possible to obtain more game medium than in the basic game, a state in which it is possible to obtain a game medium in a higher probability than in the basic game, a state in which a game medium is less consumed than in the basic game, and the like. Specifically, a free game, a second game and the like are examples of the bonus game.

The memory card 53 stores a game program and a game system program therein. The game program includes a stop symbol determining program. The stop symbol determining program is a program for determining a symbol (code number corresponding to the symbol) to be stopped on the payline L. The stop symbol determining program includes symbol weight data corresponding to each of plural payout rate (for example, 80%, 84%, 88%). The symbol weight data is data representing a correspondence relation between the code number of each symbol and 1 or plural random numbers belonging to a predetermined numerical range (0˜256) for each of the display windows 151˜155.

The payout rate is determined on the basis of data for setting a payout rate, which is outputted from the GAL 54, and a stop symbol is determined on the basis of the symbol weight data corresponding to the payout rate.

Further, the memory card 53 stores various data used for the game program and the game system program. Specifically, the data representing a relationship between the symbols 180 displayed in the display windows 151˜155 and the code numbers is stored in a data table form shown in FIG. 9. In addition, data representing a relationship between a symbol, a payout ranking and a scatter flag is stored in a payout ranking setting table form of FIG. 12. Furthermore, data representing a relationship between a payout ranking, a display-number and a payout is stored in a payout setting table form of FIG. 13. The data tables in FIGS. 12 and 13 will be specifically described later. Further, the memory card 53 stores the selection object symbols 181 to be displayed in the selection windows 161, 162, 163. In the mean time, these data are transmitted to a RAM 43 of the motherboard 40 when executing the game program.

In addition, the card slot 53S is structured to insert and remove the memory card 53 and connected to the motherboard 40 through an IDE bus. Accordingly, it is possible to change a type or content of a game to be executed in the slot machine, by removing the memory card 53 from the card slot 53S, writing another game program and game system program in the memory card 53 and inserting the memory card 53 into the card slot 53S.

The game program includes a program relating to a game progress and a program for shifting a gaming state into a bonus game.

The GAL 54 is provided with plural input and output ports. When the data is inputted into the input ports, the GAL 54 outputs data corresponding to the inputted data from the output ports. The data outputted from the output ports is the data for setting a payout rate which has been described above.

The IC socket 54S is structured to attach and detach the GAL 54. The IC socket 54S is connected to the motherboard 40 through a PCI bus. Accordingly, it is possible to change the data for setting a payout rate which is outputted from the GAL 54, by detaching the GAL 54 from the IC socket 54S, rewriting the program stored in the GAL 54 and then attaching the GAL 54 to the IC socket 54S.

The ROM 55 stores nation identification information and an authentication program. The boot ROM 52 stores a preliminary authentication program and a program (boot code) enabling the CPU 51 to execute the preliminary authentication program.

The authentication program is a program (falsification check program) for authenticating the game program and the game system program. The authentication program is a program for confirming and verifying that the game program and the game system program are not falsified. In other words, the authentication program is described in accordance with a procedure for authenticating the game program and the game system program. The preliminary authentication program is a program for authenticating the authentication program. The preliminary authentication program is described in accordance with a procedure for verifying that the authentication to be authenticated is not falsified, i.e., for authenticating the authentication program.

The motherboard 40 is provided with a main CPU 41 (controller), a ROM (Read Only Memory) 42, a RAM (Random Access Memory) 43 and a communication interface 44.

The main CPU 41 has functions of a controller for controlling the whole slot machine 10. In particular, the main CPU 41 carries out a control for outputting a command signal enabling the sub CPU to scroll the symbols of the lower image display panel 16 when the spin button 23 is pushed after the credit is bet, a control for determining symbols to be stopped after the symbols are scrolled and a control for stopping the determined symbols in the display windows 151˜155.

In other words, the main CPU 41 has functions of an arrangement controller for selecting and determining arrangement symbols with regard to a symbol matrix from the plural types of symbols so as to rearrange them, as a new symbol matrix after scrolling the plural symbols to be displayed in the lower image display panel 16, and executing an arrangement control which will be stopped at the determined symbols from the scroll state.

In addition, the main CPU 41 has functions of the game controller 100 for executing a first process of setting at least one of the selection object symbols 181 having a type corresponding to a selection signal inputted from the touch panel 69, as a scatter symbol, a second process of setting payout rankings for the scatter symbols set, based on payout ranking signals inputted from the exterior, a third process of rearranging the symbols 180 to award a payout determined by a combination of the symbols 180 rearranged on the payline L and a fourth process of awarding a payout determined on the basis of the scatter symbols 182 rearranged on and out of the payline L and the payout rankings.

The ROM 42 stores a program such as BIOS (Basis Input/Output System) executed by the main CPU 41, and data that is permanently used. When the BIOS is executed by the main CPU 41, each of peripheral devices is initialized and the game program and the game system program stored in the memory card 53 are read out through the gaming board 50.

The RAM 43 stores the data or program which is used when the CPU 41 carries out a process. For example, in the RAM 43, the selection object symbol memory 105, the scatter symbol memory 106, the symbol memory 108, the display symbol memory 107 and the payout ranking memory 118 shown in FIG. 2 are provided in a data area form, respectively. The data area of the selection object symbol memory 105 stores the selection object symbols 181. The data area of the scatter symbol memory 106 stores the scatter symbols 182. The data area of the symbol memory 108 stores the symbols 180 in the data table form shown in FIG. 8. The data area of the display symbol memory 107 stores the symbols 180, the selection object symbols 181 and the scatter symbols 182.

In addition, the data area of the payout ranking memory 118 stores the payout rankings corresponding to the scatter symbols 182. In other words, the data of the payout ranking setting table in FIG. 12 and the data of the payout table in FIG. 13 are stored.

The communication interface 44 is provided to communicate with a host computer and the like through a communication line, which are mounted in the game arcade. In addition, the motherboard 40 is connected to the main body PCB (Printed Circuit Board) 60 and the door PCB 80 through a USB (Universal Serial Bus). Further, the motherboard 40 is connected to a power unit 45. When power is supplied to the motherboard 40 from the power unit 45, the main CPU 41 of the motherboard 40 is operated and the power is supplied to the gaming board 50 through the PCI bus, so that the CPU 51 is also operated.

The main body PCB 60 and the door PCB 80 are connected to a device or apparatus for producing an input signal which will be inputted to the main CPU 41, and a device or apparatus which is controlled by the control signal outputted from the main CPU 41. The main CPU 41 executes the game program and the game system program stored in the RAM 43, based on the input signal inputted to the main CPU 41 to carry out an arithmetic process, thereby storing a result thereof in the RAM 43 or transmitting a control signal to each device or apparatus to control it.

The main body PCB 60 is connected with a lamp 30, the sub CPU 61, a hopper 66, a coin sensor 67, a graphic board 68, the speaker 29, the touch panel 69, the bill validator 22, the ticket printer 35, the card reader 36, a key switch 38S and the data displayer 37.

The lamp 30 is turned on/off on the basis of the control signal outputted from the main CPU 41. The sub CPU controls the scroll of symbols of the display windows 151˜155 and is connected to a VDP (Video Display Processor). The VDP reads out image data of the symbol stored in an image data ROM, produces a scroll image to be displayed in the display windows 151˜155 and outputs the scroll image in the lower image display panel 16.

The hopper 66 is mounted in the cabinet 11 and pays out predetermined number of coins to the coin tray 18 from the coin payout slot 19, based on the control signal outputted from the main CPU 41. The coin sensor 67 is mounted in the coin payout slot 19 and outputs an input signal to the main CPU 41 when it detects that the predetermined number of coins are paid out from the coin payout slot 19.

The graphic board 68 controls image displays in the upper image display panel 33 and the lower image display panel 16, based on the control signal outputted from the main CPU 41. In addition, the graphic board 68 is provided with a VDP for producing image data on the basis of the control signal outputted from the main CPU 41, a video RAM for temporarily storing the image data produced by the VDP, and the like.

The bill validator 22 reads out an image of the bill and accommodates the normal bill in the cabinet 11. In addition, in accommodating the normal bill, the bill validator 22 outputs an input signal to the main CPU 41, based on an amount of the bill. The main CPU 41 stores a credit-number, which corresponds to the amount of the bill transmitted by the input signal, in the RAM 43.

The ticket printer 35 prints a barcode having data encoded thereto, such as credit-number stored in the RAM 43, date and time, identification number of the slot machine 10 and the like, on a ticket, based on the control signal outputted from the main CPU 41, thereby outputting the ticket 39 having the barcode.

The card reader 36 reads the data from the smart card to transmit it to the main CPU 41, and writes the data into the smart card, based on the control signal outputted from the main CPU 41. The key switch 38S is mounted to the keypad 38, and outputs an input signal to the main CPU 41 when the player manipulates the keypad 38. The data displayer 37 displays the data which is read by the card reader 36 or the data which the player inputs through the keypad 38, based on the control signal outputted from the main CPU 41.

The door PCB 80 is connected with the control panel 20, a reverter 21S, a coin counter 21C and a cold cathode tube 81. The control panel 20 is provided with a spin switch 23S corresponding to the spin button 23, a change switch 24S corresponding to the change button 24, a cash out switch 25S corresponding to the cash out button 25, a 1-BET switch 26S corresponding to the 1-BET button 26 and a MAX-BET switch 27S corresponding to the MAX-BET button 27. Each of the switches 23S˜27S outputs an input signal to the main CPU 41 when each of the corresponding buttons 23˜27 is pushed by a player.

The coin counter 21C is mounted in the coin receiving slot 21 and validates whether a coin, which is inserted in the coin receiving slot 21 by the player, is normal or not. A coin except the normal coin is discharged from the coin payout slot 19. In addition, the coin counter 21C outputs an input signal to the main CPU 41 when it detects a normal coin.

The coin counter 21C is operated on the basis of the control signal outputted from the main CPU 41 and distributes a coin, which is recognized as a normal coin by the coin counter 21C, to a cash box (not shown) or hopper 66 mounted in the slot machine 10. In other words, when the hopper 66 is fully filled with the coins, the normal coin is distributed into the cash box by the reverter 21S. In the mean time, when the hopper 66 is not fully filled with the coins, the normal coin is distributed into the hopper 66. The cold cathode tube 81 functions as a backlight mounted to rear sides of the lower image display panel 16 and the upper image display panel 33 and is turned on, based on the control signal outputted from the main CPU 41.

(Data Table)

In the followings, it will be described the payout ranking setting table in FIG. 12. The table has a symbol column, a payout ranking column and a scatter flag column. The symbol column stores five types of symbols consisting of “BELL,” “CHERRY,” “ORANGE,” “STRAWBERRY” and “PLUM.” The payout ranking column is adapted to store any one of data representing 5 stages of payout rankings consisting of “A1˜A5.” In the mean time, the payout rankings becomes higher from “A1” to “A5.”

In addition, the scatter flag column stores any one scatter flag of “1” and “0.” The scatter flag of “1” represents that a symbol of the row thereof is set as a scatter symbol. In other words, when the scatter flag is “1,” the selection object symbol 181 is moved to the scatter symbol display unit 171 of FIG. 1. Meanwhile, the scatter flag of “0” represents that a symbol of the row thereof is not set as a scatter symbol.

In the followings, it will be described the payout setting table in FIG. 13. The table has a payout ranking column and a payout-number column. The payout ranking column corresponds to the data of the payout ranking column in FIG. 13. In other words, for example, in case that “A1,” “A2,” “A3,” “A4” and “A5” are set for “BELL,” “CHERRY,” “ORANGE,” “STRAWBERRY” and “PLUM”, respectively, the payout ranking column in FIG. 13 is same as a state of storing “BELL,” “CHERRY,” “ORANGE,” “STRAWBERRY,” “PLUM,” “BLUE 7,” “JACKPOT 7” and “APPLE”, respectively.

The display-number column is subdivided into a display-number column of 1˜3, display-number columns of 4˜5 and a display-number column of 6 or more. Each of the display-number columns stores a payout-number of coins, correspondingly to the payout rankings. Specifically, when a display-number of “BLUE 7” is one, 20 coins are paid out. In addition, for example, with regard to a case where ♭A2” of the payout rankings is set for “BELL” and the scatter flag is “1,” when a display-number is 2, 8 coins are paid out.

(Processing Operation)

In the followings, it will be described a process which is carried out in the slot machine 10. When the main CPU 41 reads out and executes the game program, a game is started. As shown in FIG. 14, in the game executing process, it is determined whether a coin is bet (S10). In this process, it is determined whether it is received an input signal from the 1-BET switch 26S as the 1-BET button 26 is pushed and whether it is received an input signal from the MAX-BET switch 27S as the MAX-BET button 27 is pushed. When the coin is not bet (S10, NO), the step of S10 is re-executed and it is under standby state until a coin is bet.

In the mean time, when the coin is bet (S10, YES), the credit-number stored in the RAM 43 is subtracted, correspondingly to the number of coins bet (S11). Meanwhile, if the number of coins bet is larger than the credit-number stored in the RAM 43, it is not carried out the process of subtracting the credit-number and the step of S11 is re-executed. In addition, if the number of coins bet is above the upper limit (50 pieces in this embodiment) which can be bet per one game, it is not carried out the process of subtracting the credit-number and a step of S12 is carried out.

Next, a scatter symbol selecting process is carried out (S12). Specifically, it is carried out a scatter symbol selecting process routine in FIG. 15. First, as shown in FIG. 3, it is determined the selection object symbols 181 as the number of the selection windows 161, 162, 163 by lottery (S100). After that, the determined selection object symbols 181 are displayed in the selection windows 161, 162, 163. For example, “BELL,” “CHERRY” and “ORANGE,” which are the selection object symbols 181, are displayed, respectively (S101). In addition, at the same time, the received things (scatter symbols 182) of the scatter symbol display units 171 disappear.

Thereby, the player can intuitively recognize that the player can select the scatter symbol 182 among the selection object symbols 181 by observing a state in which the received thing is not displayed in the scatter symbol display units 171 and a state in which the selection object symbols 181 are displayed in the selection windows 161, 162, 163, with naked eyes. In addition, the player can enjoy that the player can freely select the scatter symbol 182 among the plural types of selection object symbols 181.

In addition, since the selection object symbols 181 are determined by the lottery, it is high a possibility that types thereof may different every time. Thereby, the player can enjoy that the player can play a next game using the scatter symbols 182 having a type different from the scatter symbols 182 used in the previous game. As a result, since types of the selectable selection object symbols 181 are varied, it is easily preferred by a player who cares about a jinx.

Next, as shown in FIG. 4, when the touch panel 69 is pushed by a player's hand 190, a touch panel signal outputted from the touch panel 69 is introduced (S102). After that, it is determined whether the player has pushed the selection object symbol 181, based on the touch panel signal (S103). When the selection object symbol 181 has been pushed (S102, YES), the selection object symbol 181 is stored as the scatter symbol 182. In other words, the selection object symbol is stored in the data area of the RAM 43 formed as the scatter symbol memory 106 of FIG. 2 (S106). Meanwhile, at this time, in the data table in FIG. 12, the scatter flags corresponding to “BELL” and “CHERRY” are set as “1,” respectively, and the remaining scatter flag are set as “0.”

In the mean time, when the player does not push the selection object symbols 181 (S103, NO), such as a case where the player is pushing the symbols 180 of the display windows 151˜155, it is continuously determined whether allowed selection time has lapsed (S104). When the allowed selection time has not lapsed (S104, NO), the process of S102 is executed, so that it is introduced a next touch panel signal from the touch panel 69. When the allowed selection time has lapsed (S104, YES), all the scatter symbols 182 are automatically selected among the selection object symbols 181 (S105). Then, the selection object symbols 181 are stored as the scatter symbols 182 (S106).

After that, as it is displayed that the selection object symbol 181 pushed is moved to the scatter symbol display unit 171 from the selection windows 161, 162, 163, it is notified that the scatter symbol 182 has been set (S107). Then, it is determined whether all selections have been completed, i.e., whether the scatter symbols 182 are displayed in all the scatter symbol display units 171, as a received thing (S108). When all selections have not been completed (S108, NO), the process is re-executed from S102 and it is started a next selection of the scatter symbol 182.

When all selections have been completed (S108, YES), it is notified that a payout setting is allowed, as shown in FIG. 5. Specifically, the scatter symbol display units 171 are flickered and it is displayed a phrase such as “please, set payout rankings.” (S109). After that, as shown in FIG. 6, when the player pushes the touch panel 69, it is introduced a touch panel signal outputted from the touch panel 69 (S110). Then, based on the touch panel signal, it is determined whether the player has pushed the scatter symbol display unit 171 (S111). [0123]When the scatter symbol display unit 171 is pushed (S111, YES), it is set a payout ranking for the scatter symbol 182 pushed (S114).

Specifically, in the data table of FIG. 12, it is set a ranking having a lower payout ranking (i.e., a ranking disadvantageous to the player) with respect to the display-number of the scatter symbol display unit 171. In other words, “A1” and “A2” are selected among “A1”˜“A5.” Then, for example, when the touch panel 69 is pushed for a part corresponding to the scatter symbol display unit 171, the payout ranking of the scatter symbol 182 in the scatter symbol display unit 171 is changed every predetermined time. Then, when the player takes away the hand 190 from the touch panel 69, a payout ranking is set at the timing. In the mean time, the payout ranking may be set in such a manner that the payout ranking is varied whenever the touch panel 69 is pushed.

When the payout ranking is varied, a size of the scatter symbol display unit 171 is enlarged and downscaled. Thereby, the player can easily set a desired payout ranking by checking the size with naked eyes while pushing the scatter symbol display unit 171. In FIG. 8, the enlarged scatter symbol display unit 171 receives the scatter symbol 182 of “CHERRY,” while the downscaled scatter symbol display unit 171 receives the scatter symbols 182 of “BELL.” Accordingly, in this case, in the data table of FIG. 12, the payout ranking corresponding to “CHERRY” becomes “A2,” while the payout ranking corresponding to “BELL” becomes “A1.” The payout rankings of the other symbols may be set automatically or set into a default preset.

In addition, when the scatter symbol display unit 171 is not pushed (S111, NO), it is continuously determined whether the allowed selection time has lapsed (S112). When the allowed selection time has not lapsed (S112, NO), the process of S110 is carried out, so that it is introduced a next touch panel signal from the touch panel 69. When the allowed selection time has lapsed (S112, YES), it is set automatically the payout rankings for all the scatter symbols 182. Then, the selection object symbols 181 are memorized as the scatter symbols 182 (S106).

In the processes of S113 and S114, when the payout rankings are set manually and automatically, it is determined whether it has been completed the setting of all payout rankings (S115). When all settings have not been completed (S115, NO), the process is re-executed from S110. Meanwhile, when all settings have been completed (S115, YES), this routine is ended and the process is returned to the game execution processing routine in FIG. 14.

As shown in FIG. 14, when the execution is returned to the game execution processing routine, it is determined whether the spin button 23 is ON or not (S13). When the spin button 23 is not ON (S13, NO), the process is returned to the step of S10. Meanwhile, in case that the spin button 23 is not ON (for example, the spin button 23 is not ON and an instruction to end the game is inputted), it is canceled the subtraction result in the step of S11.

In the mean time, when the spin button 23 is ON (S13, YES), a symbol determining process is executed (S14). In other words, a stop symbol determining program stored in the RAM 43 is executed, so that it is determined the symbols 180 which will be stopped in the fifteen respective stages of the display windows 151˜155. Thereby, it is determined a combination of symbols to be stopped on the payline L.

Next, as shown in FIG. 7, the symbols 180 of the display windows 151˜155 are scroll-displayed (S15). In the mean time, the scroll process is such that the symbols 180 are scrolled in an arrow direction and then the symbols 180 determined in the step of S14 are stopped (rearranged) in the display windows 151˜155.

Next, as shown in FIG. 8, it is determined whether a combination of symbols 180 stopped on the payline L is a winning combination or not (S16). When it is not a winning combination (S16, NO), it is continued to determine whether the scatter symbol 182 is displayed (rearranged) in the display windows 151˜155 (S17). When the scatter symbol 182 is not displayed (S17, NO), this routine is ended.

In the mean time, when it is a winning combination (S16, YES) and/or the scatter symbol 182 is displayed (S17, YES), a payout process of S18 is executed. In other words, when it is made a winning of the winning combination, it is calculated a payout-number of coins based on the winning. In addition, as shown in FIG. 13, when it is made a winning of the scatter symbol 182, it is calculated a payout-number of coins based on the display-number of the scatter symbol 182 on the basis of the symbol, the payout ranking, the display-number and the scatter flag. Then, it is summed up the payout-number of coins based on the winning combination and the payout-number of coins based on the scatter symbol 182.

In case that the paid out coins are deposited, a predetermined credit-number is added to the credit-number stored in the RAM 43. In the mean time, in case that the coins are paid out, a control signal is transmitted to the hopper 66 to pay out a predetermined number of coins.

In the mean time, in the display states of FIGS. 1 and 8, it is not made a winning combination. Meanwhile, the five scatter symbols 182 (“BELL”) and the four scatter symbols 182 (“CHERRY”) are displayed. Accordingly, as shown in FIG. 13, a total sum of 5 corresponding to the display-number of “BELL” and 8 corresponding to the display-number of “CHERRY” becomes a payout-number of coins (S18).

Next, it is determined whether it is made a bonus trigger as a winning combination. In other words, it is determined whether a combination of “APPLE” is arranged on the payline L (S19). When it is determined that the bonus trigger is made (S19, YES), it is executed a bonus game process (S20). In the mean time, when the bonus trigger is not made (S19, NO), it means a losing. As a result, this routine is ended.

Embodiment 2

It will be described an embodiment 2 of the slot machine 10 and the playing method thereof, according to the invention. In the mean time, the same members as the embodiment 1 are referred to with the same reference numerals and descriptions thereof are thus omitted.

As shown in FIG. 16, the slot machine carries out a playing method comprising steps of: receiving selection of the scatter symbol 182 after a next game, in case that it becomes a predetermined unit game-number after selecting the scatter symbol 182; and changing a selection-number of the selection object symbols 181 in case of receiving the selection of the scatter symbol 182, in addition to the steps of the playing method in the embodiment 1. In the mean time, FIG. 16 shows a state in which three scatter symbols 182 consisting of “BELL,” “CHERRY” and “ORANGE” are selected among the five selection object symbols 181. The other structures are same as the embodiment 1.

The slot machine 10 of the invention has a display unit (display) 101 and a game controller 100, as shown in FIG. 17. The display unit 101 has a payline L and is structured to arrange plural symbols including scatter symbols.

The game controller 100 is structured to execute a sixth process of receiving selection of the scatter symbol after a next game in case that it becomes a predetermined unit game-number after selecting the scatter symbol, in addition to the first to fifth processes of the embodiment 1. Further, the slot machine 10 is structured to execute a seventh process of changing a selection-number of the selection object symbols in case of receiving the selection of the scatter symbol. In other words, the game controller 100 has plural types of selection object symbols and first, second, third, fourth, fifth, sixth and seventh processing units.

(Game Controller 100)

The game controller 100 is provided with a game count unit 114 to which a game start signal is inputted from a game start unit 109, a selection start determining unit 115 to which a count value signal is inputted from the game count unit 114 and a display-number lottery unit 116 to which a determining signal is inputted from the selection start determining unit 115.

Whenever a game start signal is inputted, the game count unit 114 counts up a unit game-number and outputs a unit game-number as a count value signal. When the unit game-number of the count value signal is a predetermined number, the selection start determining unit 115 outputs a selection start signal to the display lottery unit 116 and the game count unit 114. The game count unit 114 clears the unit game-number to “0”, based on the selection start signal inputted. In the mean time, the display lottery unit 116 determines a display-number of the selection object symbols with the input of the selection start signal as trigger, and determines the selection object symbols as the display-number. Further, the display lottery unit 116 determines a display-number of the scatter symbol display units 117 in FIG. 17 with the input of the selection start signal as trigger. In addition, the display lottery unit 116 outputs the selection object symbols as the display-number to the display symbol memory 107 from the selection object symbol memory 105, thereby displaying the selection object symbols as the display-number in the display unit 101. The other structures are same as the embodiment 1.

In the structure as described above, an operation of the slot machine 100 is described.

Whenever a game start signal is inputted from the game start unit 109, the unit game-number is counted up in the game start unit 109. The unit game-number is outputted to the selection start determining unit 115, as a count value signal. When the unit game-number is a predetermined number, a selection start signal is outputted to the game start unit 109. Then, a display-number of the selection object symbols is determined and the selection object symbols as the display-number are determined in the display lottery unit 116. After that, the selection object symbols as the display-number are outputted to the display symbol memory 107 from the selection object symbol memory 105, so that the selection object symbols as the display-number are displayed in the display unit 101. The other operations are same as the embodiment 1.

As a result, the game controller 100 carries out the sixth process of receiving selection of the scatter symbol after a next game, in case that it becomes a predetermined unit game-number after selecting a scatter symbol on the basis of the selection object symbols displayed in the display unit 101. In addition, the game controller 100 executes the seventh process of changing a selection-number of the scatter symbol in case of receiving the selection of the scatter symbol.

As can be clearly seen from the above operations, the slot machine 10 embodies a playing method of receiving selection of the scatter symbol after a next game, in case that it becomes a predetermined unit game-number after selecting the scatter symbol. In addition, the slot machine 10 embodies a playing method of changing a selection-number of the selection object symbols in case of receiving the selection of the scatter symbol.

(Display State)

It is specifically described an example of a display state in the display unit 101 during the operations of the slot machine 10 and the playing method thereof. A display state in the display unit 101 of FIG. 16 shows a state allowing three scatter symbols 182 to be selected among the three selection object symbols 181. In addition, as in the embodiment 1, the selection object window 165 is provided below the selection windows 161, 162, 163. The selection object window 165 displays symbols which are candidates of the selection object symbols 181. Accordingly, a player can intuitively recognize that the selection object symbols 181 are selected among the candidate symbols displayed in the selection object window 165 and then displayed in the selection windows 161, 162, 163.

(Processing Operation)

The slot machine 10 has the same mechanical and electrical structures as the embodiment 1, except that the process routine in FIG. 16 is replaced with process routines in FIGS. 18 and 19. In the followings, it will be specifically described a processing operation of the slot machine 10.

In the game executing process of FIG. 14, when a scatter symbol selecting process is executed (S12), a scatter symbol process routine of FIG. 18 is carried out. First, a unit game-number is counted up (S200). Then, it is determined whether the unit game-number is a predetermined value (S201). When the unit game-number is not a predetermined value (S201, NO), this routine is ended and the process is returned to the game executing process of FIG. 14. Accordingly, in this case, a unit game is repeated using a same type of scatter symbols 182.

In the mean time, when the unit game-number is a predetermined value (S201, YES), a display-number is determined by lottery (S202). Then, the selection object symbols 181 as the display-number are determined by lottery (S203). The selection object symbols 181 determined are displayed in the selection windows 161, 162, 163 (S204). As a result, the player can recognize that the scatter symbols 182 can be selected after playing a predetermined number of games. In addition, the player can enjoy that it is possible to play a next game using a different type of scatter symbols 182 from the scatter symbols 182 to date. Furthermore, since the type or number of the selectable selection object symbols 181 is varied, it is easily preferred by a player who cares about a jinx.

Next, a selection-number is determined by lottery (S205). After that, the scatter symbol display units 171 having a basket shape are displayed as the selection-number (S206). Thereby, the player can have an impression that the selection object symbols 181 of the selection windows 161, 162, 163 are received, by observing the basket shape with naked eyes. In addition, the player can easily understand a setting-number which can be set for the scatter symbols 182, in accordance with a display-number of the scatter symbol units 171 having the basket shape. [0150]After that, it is introduced a touch panel signal from the touch panel 69 through the operation of the player (S207). Then, it is determined whether the player has pushed the selection object symbol 181, based on the touch panel signal (S208). When the selection object symbol 181 has been pushed (S208, YES), the selection object symbol 181 is memorized as a scatter symbol 182 (S211). Then, the scatter symbol 182 memorized is displayed (S212) and then a step of S213 is executed.

In the mean time, when the selection object symbol 181 is not pushed (S208, NO), it is continuously determined whether the allowed selection time has lapsed (S209). When the allowed selection time has not lapsed (S209, NO), the process of S207 is executed, so that it is introduced a next touch panel signal from the touch panel 69. When the allowed selection time has lapsed (S209, YES), the selection object symbol is automatically selected among the selection object symbols 181 displayed in the selection windows 161, 162, 163 (S210), and then memorized as a scatter symbol 182 (S211).

After that, the selection object symbol 181 selected is moved to the scatter symbol display unit 171 and is displayed as a received thing of the scatter symbol display unit 171, so that it is notified that the selection object symbol 181 selected has been set as the scatter symbol 182 (S212). Then, it is determined whether all selections have been completed, i.e., whether the scatter symbols 182 are displayed as a received thing in all the scatter symbol display units 171 (S213). When all selections have not been completed (S213, NO), the process is re-executed from S207 and it is started next selection of the scatter symbol 182.

When the selections of all the scatter symbols 182 have been completed (S213, YES), as shown in FIG. 19, it is notified that a payout setting is allowed, as in the embodiment 1 (S214). After that, a touch panel signal is introduced (S215). Then, based on the touch panel signal, it is determined whether the player has pushed the scatter symbol display unit 171 (S216).

When the scatter symbol display unit 171 has been pushed (S216, YES), it is set a payout ranking for the scatter symbol 182 pushed (S219). In the mean time, when the scatter symbol display unit 171 has not been pushed (S216, NO), it is continued to determine whether the allowed selection time has lapsed (S217). When the allowed selection has not lapsed (S217, NO), the process of S215 is executed, so that it is introduced a next touch panel signal from the touch panel 69. When the allowed selection time has lapsed (S217, YES), it is automatically set the payout rankings for all the scatter symbols 182 (S218).

After that, when the payout rankings are manually and automatically set in the processes of S219 and S218, it is determined whether all the settings of the payout rankings have been completed (S220). When all the settings have not been completed (S220, NO), the process is re-executed from S215. In the mean time, when all the setting have been completed (S220, YES), the unit game-number is cleared to “0” (S221) and the process is then returned to the game execution processing routine from this routine. The other operations are same as the embodiment 1.
