Abstract

Provided is a gaming machine capable of suppressing the capacity of main storage means for storing a game program for the processing even if processing executed on a main board is added.
A main board 21 generates a random number for each game. The random number is processed by executing the ART lottery program P2 stored in the ROM 32, that is, the ART lottery using the random number is executed, and the result is output. On the other hand, a random number used in the ART lottery program P2 is transmitted from the main board 21 to the sub board 22 for each game. The ROM 42 of the sub-board 22 stores an ART lottery program P5 that outputs the same result as the ART lottery program P2 for the same random number. The sub board 22 uses the random number received from the main board 21 to execute the ART lottery program P5 stored in the ROM 42, and outputs the result.

Description

  The present invention relates to a gaming machine such as a slot machine.

  For example, in a slot machine, when a start lever is operated after a medal is inserted or a bet is operated by operating a bet button, three reels arranged side by side start to rotate all at once. A plurality of types of symbols are drawn on the peripheral surface of each reel. In addition, a plurality of winning combinations are set, and when the start lever is operated, a winning lottery regarding the winning combinations is performed. When a reel stop button provided in association with each reel is operated, the reel corresponding to the operated reel stop button stops. When a combination of symbols corresponding to any combination is arranged on the winning line when all the reels are stopped, the combination is awarded, and depending on the combination, a predetermined number of medals are paid out. The above is one game of the slot machine.

  In the mainstream slot machines in recent years, the number of medals to be paid out differs depending on the order in which the three reel stop buttons are pressed, and the replay role that allows the execution of one game without the betting of medals for the role that is the target of the role lottery. Includes push order small roles. The game state includes a normal state and an RT (replay time) state in which the winning probability of the replay role in the role lottery is higher than in the normal state. Further, an AT (Assist Time) function is provided for guiding the correct pressing order of the pressing order small role by displaying on a liquid crystal display or the like.

  In this type of slot machine, when the AT function is activated and the game state shifts from the normal state to the RT state, the game state becomes an ART (assist replay time) state. In the ART state, the winning probability of the replay combination is higher than in the normal state, and when the push order small combination is won in the combination lottery, the AT function notifies the correct push order of the push order small combination. Therefore, in the ART state, the player can win a medal by winning a prize without losing the push order small portion without reducing the number of possessed medals (the number of possessed balls).

  Whether to change the gaming state from the normal state to the ART state (whether the AT function is activated) is determined by ART lottery (AT lottery). The ART lottery is performed, for example, on a sub-board that is communicably connected to the main board on which the winning lottery is performed when a rare small winning combination with a low winning probability is won in the winning lottery. In this case, a combination notification command for notifying the winning combination in the combination lottery is transmitted from the main board to the sub-board. Then, when a role notification command indicating that a rare small role is won in the role lottery is received by the sub-board, the ART lottery is performed on the sub-board using this as a trigger.

  From the main board, in addition to the role notification command, a start notification command for notifying operation of the start lever, an RT transition notification command for notifying game state transition, and the like are transmitted to the sub-board. When processing such as an ART game number determination lottery for determining the number of games in which the ART state continues on the main board and a breeze effect lottery for determining whether or not to execute an effect due to reel freeze is executed. A command notifying the result is transmitted from the main board to the sub board.

  There are multiple results for one process. Therefore, the processing program includes a plurality of commands for notifying the processing result from the main board to the sub board. Therefore, the data amount of the program is large even for the command alone. For example, if the data amount of one command is 4 bytes and the number of commands is 19, the data amount of the program is 76 bytes only for the command.

  However, the use of the capacity of the ROM mounted on the main board is limited for the purpose of preventing illegal purposes. For example, the capacity available for the program code is limited to 4.5 KB (kilobytes). Therefore, the capacity for the program code in the ROM is squeezed only by adding one process executed on the main board.

  An object of the present invention is to provide a gaming machine that can suppress the compression of the capacity of main storage means for storing a game program for the processing even if processing to be executed on the main board is added. is there.

  In order to achieve the above object, a gaming machine (1) according to the present invention includes a main board (21) and a sub board (22) connected to be communicable in one direction from the main board (21). A machine (1) provided on the main board (21) and provided on the main board (21) and game information generating means (13, 37) for generating game information about a game for each game. A main storage means (32) for storing a game program for outputting a result of processing the game information; and the game provided on the main board (21) and generated by the game information generation means (13, 37). The main execution means (31) for executing the game program stored in the main storage means (32) using the information, and the game program for each game. Information transmitting means (35) for transmitting the game information used in the ram to the sub-board (22), and the game program provided in the sub-board (22) and stored in the main storage means (32) Sub-storage means (42) for storing a sub-program that outputs the same result when the same game information is processed, and provided on the sub-board (22) and transmitted by the information transmission means (35) Sub-execution means (41) for executing the subprogram stored in the sub-storage means (42) using the game information.

  According to this configuration, game information is generated for each game on the main board (21). And the game information is processed by the game program memorize | stored in the main memory | storage means (32) being processed, and the result of the process is output. On the other hand, game information used in the game program is transmitted from the main board (21) to the sub board (22) for each game. The sub storage means (42) of the sub board (22) stores a sub program that outputs the same result when the same game information as the game program is processed. In the sub board (22), the game information received from the main board (21) is used to execute the sub program stored in the sub memory means (42), and the result of processing the game information is output. .

  Thereby, the same result which processed the same game information can be obtained in both the main board | substrate (21) and a sub board | substrate (22). Therefore, it is not necessary to transmit a command for notifying the result of processing the game information on the main board (21) from the main board (21) to the sub board (22). Therefore, the data amount of the game program is smaller than the data amount of the program created so that the command for notifying the result of processing the game information is transmitted from the main board (21) to the sub board (22).

  Therefore, even if a process to be executed on the main board (21) is added, the data amount of the game program for the process is small, so that the capacity of the main storage means (32) can be suppressed.

  The game information generating means (13, 37) includes random number generating means (37) for generating a random number, and the game information may be a random number generated by the random number generating means (37). The game program includes, as one of them, a program for executing a lottery regarding an advantageous game state, which is a game state advantageous to the player, using a random number generated by the random number generation means (37). May be.

  Specifically, the game program may include a program for executing a game state transition lottery for determining whether or not to shift the game state from the normal state to the advantageous game state.

  As an advantageous game state, for example, an ART state in a slot machine can be cited. In this case, the game state transition lottery is an ART lottery that determines whether or not to shift the game state from the normal state to the ART state. In the conventional slot machine, the program for executing the ART lottery is stored only in the ROM of the sub-board in order to avoid squeezing the capacity for the program code in the ROM of the main board. Executed. Therefore, the main board cannot accurately grasp whether or not the game state has shifted from the normal state to the ART state.

  When the game program executed on the main board (21) includes a program for executing the game state transition lottery, the game state is set to the normal state on the main board (21) based on the result of the game state transition lottery. It is possible to accurately grasp whether or not the game state has shifted to the advantageous game state. Therefore, the effect control (control for the main effect) by the main board (21) can be executed in synchronization with the game state transition. As a result, the game can be effectively produced according to the game state.

  In addition, since the same result as the result of the game state transition lottery executed on the main board (21) can be obtained on the sub board (22), the result of the game state transition lottery can be obtained from the main board (21). There is no need to transmit to the substrate (22). Therefore, the data amount of the program for executing the game state transition lottery is the data amount of the program created so that a command for notifying the result of the game state transition lottery is transmitted from the main board (21) to the sub board (22). Smaller than. Even if a process for executing a game state transition lottery is added as a process executed on the main board (21), it is possible to prevent the capacity of the main storage means (32) from being compressed.

  Moreover, the game program may include a program for executing a game number determination lottery for determining the number of games for which the advantageous game state is continued.

  The gaming machine (1) has an array of a plurality of types of symbols, and the symbol display means (4L, 4C, 4R) for displaying the symbols in a variable manner and stopped and the symbol display means (4L, 4C, 4R). Start instruction means (13) operated to instruct the start of the variable display of the game, and the game information generating means (13, 37) in response to the operation of the start instruction means (13). The game information may include information that the start signal is output from the start signal output means. As one of the game programs, a program for counting the number of outputs of the start signal and managing the number of games in which a predetermined game state continues may be included.

  The number of games in which a predetermined game state continues can be managed on both the main board (21) and the sub board (22). Therefore, it is not necessary to transmit the number of games managed by the main board (21) from the main board (21) to the sub board (22). Accordingly, the data amount of the game program is such that the command for notifying the number of games managed by the main board (21) is transmitted from the main board (21) to the sub board (22). Smaller than.

  Therefore, even if a process for managing the number of games is added on the main board (21), the data amount of the game program for the process is small, so that the capacity of the main storage means (32) can be suppressed from being compressed. .

  The gaming machine (1) is provided on the main board (21), and when the number of games managed by the game program reaches a predetermined number, the game state changes from a predetermined game state to a game state different from the predetermined game state. It may be configured to further include a game state transition determining means (31) for determining that the transition has been made.

  According to the present invention, even if a process to be executed on the main board is added, the data amount of the game program for the process is small, so that the capacity of the main storage unit can be suppressed from being compressed.

<Electric configuration of slot machine>

  FIG. 2 is a block diagram showing an electrical configuration of the slot machine.

  The slot machine 1 includes a main board 21 that performs central control of the game, and a sub board 22 that performs auxiliary control of the game such as control for effects accompanying the game.

  The main board 21 includes a CPU 31, a ROM 32, a RAM 33, an input / output port 34, and a signal transmission circuit 35.

  The CPU 31 is connected to the ROM 32, RAM 33, input / output port 34 and signal transmission circuit 35.

  Various programs are stored in the ROM 32. The programs include a role lottery program P1, an ART lottery program P2, a game number determination lottery program P3, and a game number management program P4. The role lottery program P1, the ART lottery program P2, the game number determination lottery program P3, and the game number management program P4 will be described later.

  The input / output port 34 is connected to the MAX bet button 12, the start lever 13, the left stop button 14L, the middle stop button 14C, and the right stop button 14R. When the MAX bet button 12, the start lever 13, the left stop button 14L, the middle stop button 14C, and the right stop button 14R are operated, an operation signal is output from a switch (not shown) incorporated therein, and the operation signal Is input to the CPU 31 via the input / output port 34. Further, stepping motors ML, MC, MR and the like for rotating the reels 4L, 4C, 4R are connected to the input / output port 34 as control targets.

  The CPU 31 keeps track of the rotational position of each reel 4L, 4C, 4R. The CPU 31 executes a program stored in the ROM 32, gives drive pulse signals to the stepping motors ML, MC, MR based on the rotational positions of the reels 4L, 4C, 4R, and rotates the reels 4L, 4C, 4R. Control. In addition, the CPU 31 executes a program stored in the ROM 32 and sends a command and a signal necessary for control to the sub-board 22 via the signal sending circuit 35. When executing the program, the CPU 31 uses the RAM 33 as a work area.

  The main board 21 is provided with a first random number generation circuit 36 and a second random number generation circuit 37. The first random number generation circuit 36 and the second random number generation circuit 37 are connected to the CPU 31. The first random number generation circuit 36 and the second random number generation circuit 37 are configured to include an increment counter that counts up in response to an output of a clock pulse from an oscillator (not shown), and each generates a 16-bit random number. .

  The sub-board 22 includes a CPU 41, a ROM 42, a RAM 43, a signal input circuit 44, and a drive circuit 45.

  The CPU 41 is connected to the ROM 42, RAM 43, signal input circuit 44, and drive circuit 45.

  Various programs are stored in the ROM 42. The programs include an ART lottery program P5, a game number determination lottery program P6, and a game number management program P7. The ART lottery program P5, the game number determination lottery program P6, and the game number management program P7 will be described later.

  The CPU 41 uses the signal input from the signal input circuit 44 from the signal transmission circuit 35 of the main board 21 to execute the program stored in the ROM 42. In addition, the CPU 41 executes a program stored in the ROM 42 and controls the display on the liquid crystal display 16 via the drive circuit 45. When executing the program, the CPU 41 uses the RAM 43 as a work area.

<Random number acquisition>

  FIG. 3 is a flowchart showing a flow of acquisition of random numbers in the main board and notification to the sub-board.

  On the main board 21, random numbers are acquired from the first random number generation circuit 36 and the second random number generation circuit 37 by the CPU 31 for each game.

  That is, the CPU 31 repeatedly determines whether or not the start lever 13 has been operated based on a lever operation signal from a switch built in the start lever 13 (step S1).

  When the start lever 13 is operated (YES in step S1), the CPU 31 acquires random numbers from the first random number generation circuit 36 and the second random number generation circuit 37 at the operated timing (step S2). .

  When a random number is acquired from the first random number generation circuit 36 and the second random number generation circuit 37, the random number acquired from the second random number generation circuit 37 is sent from the signal transmission circuit 35 of the main board 21 together with the random number notification command. The signal is transmitted to the signal input circuit 44 of the substrate 22 (step S3).

  Further, in order to notify the operation of the start lever 13, together with the start notification command, a lever operation signal output from the start lever 13 is transmitted from the signal transmission circuit 35 of the main board 21 to the signal input circuit 44 of the sub board 22 ( Step S4).

<Role drawing program>

  FIG. 4 is a flowchart showing the contents of a role lottery program executed on the main board.

  On the main board 21, the role lottery program P1 is executed by the CPU 31 for each game.

  When the role lottery program P1 is executed, the role lottery using the random number acquired from the first random number generation circuit 36 in the game is executed (step S11).

  In the role lottery, a role lottery table (not shown) stored in the ROM 32 is used. In the combination lottery table, the range of random numbers from 0 to 65535 generated by the first random number generation circuit 36 is assigned to a plurality of lottery sections, and lottery section data (random number range) and the combination are associated with each lottery section. Has been created by. It is specified in which lottery section the random number acquired from the first random number generation circuit 36 is included, and a combination or outage associated with the specified lottery section is used as the lottery result.

  For the role, for example, a rare role that has a relatively low winning probability, a normal role that has a relatively high winning probability, a left stop button 14L, a middle stop button 14C, and a right stop button 14R. And a replay combination in which the execution of one game is permitted without a bet of medals, and the like.

  In the slot machine 1, a game state is provided with a normal state and an RT (replay time) state in which the winning probability of the replay combination in the combination lottery is higher than the normal state. A lottery table is provided for each game state.

  When the result of the lottery is obtained, a role notification command representing the lottery result is transmitted from the signal transmission circuit 35 of the main board 21 to the signal input circuit 44 of the sub board 22 (step S12), and the part lottery program P1 is terminated. The

  In response to the operation of the start lever 13, the CPU 31 inputs drive pulse signals to the stepping motors ML, MC, MR, and starts to rotate the reels 4L, 4C, 4R. When the rotational speeds of the reels 4L, 4C, 4R become constant, the CPU 31 can accept operation signals from the left stop button 14L, the middle stop button 14C, and the right stop button 14R.

When the left stop button 14L, the middle stop button 14C and the right stop button 14R are selectively operated, the CPU 31 stops sending drive pulse signals to the stepping motors ML, MC, MR. Thereby, the rotation of the reels 4L, 4C, 4R is stopped. The timing for stopping the supply of the drive pulse signal to the stepping motors ML, MC, MR is controlled based on the timing at which the left stop button 14L, the middle stop button 14C and the right stop button 14R are operated and the result of the lottery drawing. The

  When the rotation of all the reels 4L, 4C, 4R is stopped, the CPU 31 determines whether or not a combination of symbols corresponding to the winning combination in the winning lottery is arranged on the activated winning line. If there is a combination of symbols corresponding to the winning combination on the winning line, it is determined that the winning combination is a winning combination. The number of medals set for each winning combination is paid out for winning.

  Thus, one game in the slot machine 1 is completed.

<ART board lottery program>

  FIG. 5 is a flowchart showing the contents of an ART lottery program executed on the main board.

  On the main board 21, the ART 31 lottery program P2 is executed by the CPU 31 for each game.

  When the ART lottery program P2 is executed, it is determined whether or not a rare small combination is won in the combination lottery in the game (step S21).

  If the rare small combination is not won in the role lottery (NO in step S21), the subsequent processing is not performed and the ART lottery program P2 is terminated.

  If a rare small role is won in the role lottery (YES in step S21), an ART lottery is executed (step S22).

  In the ART lottery, among the random numbers acquired from the second random number generation circuit 36 in the game, a numerical value consisting of a predetermined number of bits (for example, upper 4 bits) is used as a random number for the ART lottery. Further, an ART lottery table (not shown) stored in the ROM 32 is used. The ART lottery table is created by assigning a range of random numbers for ART lottery to two lottery sections, winning and not winning. By specifying which lottery category the random number for the ART lottery is included in, it is determined whether the result of the ART lottery is won or not.

  If the result of the ART lottery is a win (YES in step S23), the CPU 31 executes the game number determination lottery program P3 (step S24), and the ART lottery program P2 is terminated.

  If the result of the ART lottery is a win, the AT function under the control of the CPU 41 of the sub-board 22 is activated as will be described later. Thereafter, for example, when a specific replay combination is won and the replay combination wins, the game state is changed from the normal state to the RT state. As a result, the game state becomes an ART state that is an RT state in which the AT function is operating.

  When the result of the ART lottery is not won (NO in step S23), the ART lottery program P2 is terminated without executing the game number determination lottery program P3.

<Main board game number determination lottery program>

  FIG. 6 is a flowchart showing the contents of a game number determination lottery program executed on the main board.

  When the game number determination lottery program P3 is executed, a game number determination lottery is executed (step S31).

  In the game number determination lottery, a numerical value consisting of a predetermined number of bits (for example, lower 4 bits) among random numbers acquired from the second random number generation circuit 36 in the game is used as a random number for ART lottery. In addition, a game number determination lottery table (not shown) stored in the ROM 32 is used. The game number determination lottery table is created by assigning a range of random numbers for the game number determination lottery to a plurality of lottery categories and associating lottery category data (random number range) with the number of games for each lottery category. Yes. It is specified in which lottery category a random number for determining the number of games is included, and the number of games associated with the specified lottery category is determined as the number of games in which the ART state continues.

  When the number of continuing games in the ART state is determined by the game number determination lottery, the CPU 31 executes the game number management program P4 (step S32), and the game number determination lottery program P3 is terminated.

<Main board game number management program>

  FIG. 7 is a flowchart showing the contents of the game number management program executed on the main board.

  When the game number management program P4 is executed, it is determined whether or not the start lever 13 has been operated (step S41).

  When the start lever 13 is operated (YES in step S41), the number of remaining games (number of remaining games) in which the ART state continues is reduced by 1 (step S42).

  When the number of remaining games is decreased by 1, it is determined whether or not the number of remaining games after the decrease is 0 (step S43).

  If the number of remaining games is not 0 (NO in step S43), it is determined again whether the start lever 13 has been operated (step S41).

  When the game is repeatedly executed in the ART state and the remaining number of games becomes zero (YES in step S43), the game number management program P4 is terminated. Further, in response to the remaining number of games becoming zero, as will be described later, the AT function under the control of the CPU 41 of the sub-board 22 is stopped, so that the CPU 31 shifts the game state from the ART state to the normal state. It is judged that it was done.

<ART board lottery program>

  FIG. 8 is a flowchart showing the contents of the ART lottery program executed on the sub-board.

  On the sub-board 22, the ART lottery program P5 is executed by the CPU 41 for each game.

  When the ART lottery program P5 is executed, based on the combination notification command input from the signal transmission circuit 35 of the main board 21 to the signal input circuit 44 of the sub-board 22 in the game, a rare small combination is selected in the combination of the game. It is determined whether or not the winning is made (step S51).

  If a rare small role is not won in the role lottery (NO in step S51), the subsequent processing is not performed and the ART lottery program P5 is terminated.

  When a rare small role is won in the role lottery (YES in step S51), an ART lottery is executed (step S52), and the winning / non-winning of the ART lottery is determined.

  In the ART lottery, a numerical value consisting of a predetermined number of bits (for example, the upper 4 bits) among the random numbers input from the signal transmission circuit 35 of the main board 21 to the signal input circuit 44 of the sub board 22 in the game is an ART lottery. Used as a random number for Further, an ART lottery table (not shown) stored in the ROM 42 is used. The ART lottery table stored in the ROM 42 is the same table as the ART lottery table stored in the ROM 32 of the main board 21. Therefore, the result of the ART lottery on the sub board 22 matches the result of the ART lottery on the main board 21.

  If the result of the ART lottery is winning (YES in step S53), the CPU 41 executes the game number determination lottery program P6 (step S54), and the ART lottery program P5 is terminated.

  When the result of the ART lottery is a win, the AT function is operated under the control of the CPU 41. By the AT function, when the small combination of the pressing order is won in the winning lottery, the pressing order of the left stop button 14L, the middle stop button 14C, and the right stop button 14R that are correct is displayed (navigated) on the liquid crystal display 16.

  When the result of the ART lottery is not won (NO in step S53), the ART lottery program P5 is terminated without executing the game number determination lottery program P6.

<Sub-board game number determination lottery program>

  FIG. 9 is a flowchart showing the contents of the game number determination lottery program executed on the sub-board.

  When the game number determination lottery program P6 is executed, a game number determination lottery is executed (step S61), and the number of continuing games in the ART state is determined.

  In the game number determination lottery, a numerical value composed of predetermined bits (for example, lower 4 bits) among random numbers input from the signal transmission circuit 35 of the main board 21 to the signal input circuit 44 of the sub board 22 in the game. Used as a random number for ART lottery. Further, a game number determination lottery table (not shown) stored in the ROM 42 is used. The game number determination lottery table stored in the ROM 42 is the same table as the game number determination lottery table stored in the ROM 32 of the main board 21. Therefore, the number of continuing games in the ART state determined by the sub-board 22 matches the number of continuing games in the ART state determined by the main board 21.

  When the number of continuing games in the ART state is determined by the game number determination lottery, the CPU 41 executes the game number management program P7 (step S62), and the game number determination lottery program P6 is terminated.

<Sub-board game number management program>

  FIG. 10 is a flowchart showing the contents of the game number management program executed on the main board.

  When the game number management program P7 is executed, whether a start notification command and a lever operation signal for notifying the operation of the start lever 13 are input from the signal transmission circuit 35 of the main board 21 to the signal input circuit 44 of the sub board 22 or not. Is determined (step S71).

  When the start notification command and the lever operation signal are input to the signal input circuit 44 (YES in step S71), it is determined that the start lever 13 is operated, and the remaining number of games (number of remaining games) in which the ART state continues is determined. It is decreased by 1 (step S72).

  As described above, after the game state shifts from the normal state to the ART state, every time one game is executed, the number of remaining games managed by the main board 21 is reduced by 1 and is managed by the sub board 22. The number of remaining games played is reduced by one. As a result, the number of remaining games managed by the sub-board 22 matches the number of remaining games managed by the main board 21.

  When the number of remaining games is reduced by 1, it is determined whether or not the number of remaining games after the reduction is 0 (step S73).

  If the remaining game number is not 0 (NO in step S73), it is determined again whether the start lever 13 has been operated (step S71).

  When the game is repeatedly executed in the ART state and the remaining number of games becomes zero (YES in step S73), the game number management program P7 is terminated. Further, in response to the remaining game number becoming zero, the CPU 41 stops the AT function. As the AT function is stopped, the correct pressing order of the pressing order small combinations is not notified, so that predetermined symbols are arranged on the winning line, and the gaming state shifts (falls) from the RT state to the normal state.

<Effect>

  As described above, the main board 21 generates a random number as an example of game information for each game. The random number is processed by executing the ART lottery program P2 stored in the ROM 32, that is, the ART lottery using the random number is executed, and the result is output. On the other hand, a random number used in the ART lottery program P2 is transmitted from the main board 21 to the sub board 22 for each game. The ROM 42 of the sub-board 22 stores an ART lottery program P5 that outputs the same result as the ART lottery program P2 for the same random number. The sub board 22 uses the random number received from the main board 21 to execute the ART lottery program P5 stored in the ROM 42, and outputs the result.

  Thereby, the same result can be obtained in both the main board 21 and the sub board 22. Therefore, it is not necessary to transmit a command for notifying the result of the ART lottery on the main board 21 from the main board 21 to the sub board 22. Therefore, the data amount of the ART lottery program P2 is smaller than the data amount of the program created so that the command for notifying the ART lottery result is transmitted from the main board 21 to the sub board 22.

  Therefore, even if the process of executing the ART lottery on the main board 21 is added, the amount of data of the ART lottery program P2 for the process is small, so that the capacity of the ROM 32 can be suppressed from being compressed.

  Further, since the ART transfer lottery is executed on the main board 21, it is possible to accurately grasp whether or not the game state has shifted from the normal state to the ART state. Therefore, effect control by the main board 21 (for example, control for effect by freezing the reels 4L, 4C, 4R) can be executed in synchronization with the transition of the game state. As a result, the game can be effectively produced according to the game state.

  When the ART lottery on the main board 21 is won, the main board 21 executes the game number determination lottery program P3 stored in the ROM 32, thereby processing random numbers, that is, determining the number of games using random numbers. A lottery is executed and the result is output. On the other hand, a random number used in the game number determination lottery program P3 is transmitted from the main board 21 to the sub-board 22 for each game. The ROM 42 of the sub-board 22 stores a game number determination lottery program P6 that outputs the same result as the game number determination lottery program P3 for the same random number. The sub board 22 uses the random number received from the main board 21 to execute the ART lottery program P6 stored in the ROM 42, and outputs the result.

  Thereby, the same result can be obtained in both the main board 21 and the sub board 22. Therefore, it is not necessary to transmit a command for notifying the result of the game number determination lottery on the main board 21 from the main board 21 to the sub board 22. Therefore, the data amount of the game number determination lottery program P3 is smaller than the data amount of the program created so that the command for notifying the result of the game number determination lottery is transmitted from the main board 21 to the sub board 22.

  Therefore, even if a process of executing the game number determination lottery on the main board 21 is added, since the data amount of the game number determination lottery program P3 for the process is small, it is possible to suppress the ROM 32 from being compressed. .

  Further, when the game state shifts from the normal state to the ART state, the main board 21 executes the game number management program P4 stored in the ROM 32, whereby the remaining number of games in which the ART state continues (the number of remaining games) ) Is managed. On the other hand, a lever operation signal is transmitted from the main board 21 to the sub board 22 together with the start notification command for each game. The ROM 42 of the sub-board 22 stores a game number management program P7 that outputs the same result as the game number management program P4 as a result of processing using the lever operation signal. In the sub-board 22, when the game state shifts from the normal state to the ART state, the game number management program P7 stored in the ROM 42 is executed and the result is output.

  As a result, the number of games in which the ART state continues on both the main board 21 and the sub board 22 can be managed. Therefore, it is not necessary to transmit the number of games managed by the main board 21 from the main board 21 to the sub board 22. Therefore, the data amount of the game number management program P4 is smaller than the data amount of the program created so that the command for notifying the number of games managed by the main board 21 is transmitted from the main board 21 to the sub board 22. .

  Therefore, even if a process for managing the number of games on the main board 21 is added, since the data amount of the game number management program P7 for the process is small, it is possible to prevent the ROM 32 from being compressed.

  In addition, since the number of games is similarly managed on the main board 21 and the sub board 22, the AT function by the sub board 22 is stopped when the number of games managed on the main board 21 becomes zero. It is possible to determine that the game state has shifted from the ART state to the normal state.

<Modification>

  As mentioned above, although embodiment of this invention was described, this invention can also be implemented with another form.

  For example, the ART lottery program P2, the game number determination lottery program P3, and the game number management program P4 are taken as examples of game programs that output the results of processing game information relating to the game. It may further include an ART extra lottery for determining whether or not to add the number of games to be added, and a game number distribution lottery for determining the number of games to be added.
