The predictive presentation is configured to be switched to presentation b while presentation (a) is performed, in a manner that the rate of switching the predictive presentation to the presentation b having an expectation degree higher than that of the presentation (a), is different according to whether or not indication presentation is performed during the predictive presentation.

Description

  The present invention relates to, for example, a slot machine. Specifically, the game can be started by setting a predetermined number of bets for one game using the game value, and a variable display device capable of variably displaying a plurality of types of identification information that can be individually identified. The present invention relates to a slot machine in which one game is completed when a display result is derived, and a winning can be generated according to the display result derived to the variable display device.

  A slot machine generally includes a variable display device having a plurality of (usually three) reels having a plurality of types of symbols as identification information drawn on the outer periphery, and each reel has a start lever by a player. Rotation is started by operating, and when the player operates a stop button provided corresponding to each reel, the rotation is stopped within a range of a predetermined maximum delay time from the operation timing. . A winning is generated according to the display result derived when the rotation of all reels is stopped.

  The types of winning combinations include small roles, bonuses, and replays. Here, in the winning of a small role, the player can obtain a profit that a predetermined number of medals are paid out for each type of small role. In the bonus winning, the player can obtain a profit that the next game is shifted to a gaming state advantageous to the player, such as a regular bonus or a big bonus. In the replay winning, a profit can be obtained that the next game can be performed without consuming new medals for setting the bet amount.

  In order for winning of each combination to occur, generally, a winning flag must be set by winning an internal lottery performed in advance (usually when the start lever is operated). And, when the combination of symbols constituting the winning combination in the internal lottery can be drawn within the range of the predetermined number of frames, the effective combination is arranged, and the winning combination not in the internal lottery is configured. Reel control is performed so that the combination of symbols is not aligned with an effective line.

  In such a slot machine, continuous production is performed over a plurality of games according to the winning situation of the specific role, and the ratio of winning the specific role is further increased during execution of the continuous effect, so that the so-called high-expected continuous effect is switched. There was a thing (for example, refer to patent documents 1).

Japanese Patent No. 4671289

  However, the conventional slot machine can be switched to a continuous production with a high expectation without any prior notice. In other words, switching from a continuous production with a low degree of expectation to a continuous production with a high degree of expectation is suddenly performed. For this reason, during a period in which a continuous production with a low degree of expectation is being executed, the expectation of whether or not it can be switched to a continuous production with a high degree of expectation or at what timing will be changed. I could not. As a result, it was not possible to improve the interest of the game during the period in which the continuous performance with low expectation is being executed.

  The present invention has been devised in view of such circumstances, and its purpose is to improve the interest of the game by changing the expectation that the player has during the period during which the specific performance is executed. Is to provide a machine.

(1) A variable display device capable of starting a game by setting a predetermined number of bets for one game using a game value and variably displaying a plurality of types of identification information each of which can be identified A slot machine (slot machine 1) in which one game is ended by deriving the display result and winning can be generated according to the display result derived to the variable display device,
Privilege granting means (AT lottery processing) for granting a privilege (for example, AT) advantageous to the player as the game progresses;
Expectations for giving the privilege (expectations for giving AT games, expectations for the number of AT games to be given, etc.) in a predetermined performance period (a precursor period over 5 games) Specific effect execution means (S02, S05, S08 in FIG. 29) for executing any one of different types of specific effects (prediction effects, patterns A to F, a system effect, b system effect);
Special effect execution means (S06, S08 in FIG. 29) for executing a special effect (suggested effect) during the effect period;
And a notification effect execution means (S07, S08 in FIG. 29) for executing a notification effect (battle effect) for notifying whether or not the privilege is granted after the effect period has elapsed,
The ratio of performing the high expectation level switching (switching from the a-line effect to the b-line effect) is such that the specific effect execution means switches to a specific effect having a higher expectation level than the specific effect being executed. The high expectation level switching is performed differently depending on whether or not it has been executed (FIG. 33).

  According to such a configuration, the degree of expectation for the provision of the privilege is suggested in advance by executing the specific effect in the effect period until the notification effect for notifying whether or not the privilege is provided is executed. can do. In addition, in the production period, the expectation can be improved by performing high expectation level switching that switches to the specific production having a higher expectation level than the specific production being executed. Furthermore, depending on whether or not the special effect is executed by performing the high expectation level switching so that the ratio of the high expectation level switching is different depending on whether or not the special effect is performed in the effect period. Can have different expectations. As a result, the high expectation level switching and the privilege are given depending on whether or not the special effect is executed before the high expectation level switching is performed during the effect period in which the specific effect is executed. It is possible to change the sense of expectation that the player has in response to this, and to improve the interest of the game.

  The ratio of performing the high expectation level switching to the specific effect having a higher expectation level than the specific effect being executed is higher when the special effect is executed than when the special effect is executed. As described above, the high expectation level switching may be performed. In this case, after the specific effect execution means determines whether or not to switch the high expectation level, when it is determined that the high expectation level switching is performed, the rate is higher than when it is determined that the high expectation level switching is not performed. The special effect executing means may execute the special effect (see the embodiment), and after the special effect executing means determines whether or not to execute the special effect, it is determined to execute the special effect. The specific effect execution means may switch the high expectation degree at a higher rate than when it is determined not to execute the special effect when it is performed ([Lottery order of the sign effect and the suggestive effect in the modification) ] Column).

  The benefit is the percentage of the game value given to the player to the game value used to play the game (the number of bet medals, the game ball that is struck) (medal or game ball payout rate) It may be a value that directly affects the game (number of AT games, bonuses, etc.), and is not limited to such value, but is a value that is beneficial to the player in the progress of the game (definite effect, premier effect, latent suggestion effect) Etc.) (see “About Benefits” column in the modification).

  The degree of expectation for the granting of a privilege is, for example, the possibility that the granting condition that triggers the granting of the privilege is established, the size of the rate, and the degree of advantage for the player of the granted privilege Say goodbye.

  The effect period may be, for example, a period from the start of one game to the end, or a period over a plurality of games.

  After deciding whether or not to grant a privilege by the privilege granting means (such as AT acquisition), a specific effect, a special effect, and a notification effect are determined according to the determination result (privilege pre-determined pattern). Alternatively, after determining the specific effect, the special effect, and the notification effect, a privilege may be given (post-privilege determination pattern) in accordance with the determined result of the notification effect (modified example) [Refer to [Relationship between privilege grant and battle-related effects].)

  “The specific effect execution means is configured so that a ratio of performing high expectation level switching to a specific effect having a higher expectation level than the specific effect being executed depends on whether or not the special effect is executed. In the case of “switching the degree of expectation”, in the case where a plurality of types of specific effects (execution timing or type) are provided, “the specific effect execution means is specified with a higher expectation than the specific effect being executed. “The high expectation level switching is performed so that the ratio of the high expectation level switching to the effect varies depending on the aspect of the special effect (FIG. 33)”.

  (2) In the slot machine of (1), the special effect execution means executes the special effect so that the degree of expectation for the provision of the privilege differs according to the execution timing (FIG. 33).

  According to such a configuration, even when a special effect is executed, the degree of expectation can be varied according to the execution timing. As a result, it is possible to change a player's sense of expectation that high expectation level switching is performed according to the execution timing of the special effect and that a privilege is given, and the interest of the game can be improved. it can.

(3) In the slot machine of (1) or (2), the specific effect executing means executes the specific effect when any of a plurality of types of start conditions (AT lottery conditions) is satisfied ( When the determination in S01 of FIG. 29 is YES, the processing after S02 is executed).
The special effect execution means executes the special effect at a rate corresponding to the type of start condition established among the plurality of types of start conditions (FIG. 33).

  According to such a configuration, since the proportion of execution of the special effect varies depending on the type of the start condition that is satisfied, the player can be focused on the type of the start condition.

(4) In the slot machine of any one of the above (1) to (3), the notification effect executing means has a plurality of types of notification effects (the battle character is the character A of the character A) with different degrees of expectation for the provision of the privilege. One of the battle production and the battle character's battle production of character B),
The type of specific effect executed during the effect period (the effect of system a or the effect of system b) suggests the type of notification effect that is executed after the effect period has elapsed (FIG. 35 (b)). g) etc.).

  According to such a configuration, since the type of the notification effect is suggested by the executed specific effect, the expectation for the notification effect can be varied according to the type of the specific effect executed during the effect period. The interest of the game during the period can be improved.

  In addition, after the specific effect execution means determines the type of the specific effect, the notification effect execution means may determine and execute the type of the notification effect according to the determined type of the specific effect ( In addition, after the notification effect executing means determines the type of the notification effect, the specific effect execution means determines the type of the specific effect according to the determined type of the notification effect and executes it. There may be (refer to the [About lottery order of warning effect and notification effect] column in the modification).

(5) In the slot machine of any one of (1) to (4) above, prior determination for determining whether or not to allow generation of a plurality of types of winnings before a display result is derived to the variable display device. Means (internal lottery processing)
The plurality of types of winnings include a plurality of types of specific winnings (FIG. 26),
The special effect execution means is provided on the condition that the generation of any one of the plurality of types of specific winnings is permitted by the pre-decision means, and the type of the specific winning that is allowed to be generated. In response, the special effect is executed (FIG. 33).

  According to such a configuration, since the special effect is executed according to the type of the specific winning that is allowed to be generated, it is possible to make the player pay attention to which specific winning is allowed.

The slot machine may further include the following configuration.
(A) Control means (main control unit 41) for performing control related to the game;
Provided separately from the control means (main control section 41), can read and write data used for control of the control means (main control section 41), and even if power supply to the gaming machine is stopped Data storage means (SRAM 50) capable of holding data (backup data) for returning to the state before stopping power supply after restarting power supply;
Connecting means (such as a data bus) for connecting the control means (main control unit 41) and the data storage means (SRAM 50) so that data can be input and output;
The control means (main control unit 41)
When outputting data to be written to the data storage means (SRAM 50) via the connection means (data bus or the like), a notification signal for notifying the data storage means (SRAM 50) that the data is output Notification signal output means for outputting (chip select signal);
A specific terminal (general-purpose port terminal) provided in the control means (main control unit 41) is used as an input terminal (input terminal) for inputting a signal from the outside, or an output terminal (output) for outputting a signal to the outside Input / output setting means for setting or
Setting the terminal that outputs the notification signal (chip select signal) by the input / output setting means when the condition for stopping power supply to the gaming machine is satisfied is set as the output terminal (output terminal) To a terminal setting changing means at the time of stopping power supply to change the setting to the input terminal (input terminal).

  In a conventional slot machine, for example, when the voltage is unstable, such as when power supply is stopped, even if access to the RAM is prohibited on the CPU side, a chip select signal for specifying the RAM or writing to the RAM A write (WR) signal indicating the timing of the RAM may be output, and when these signals coincide with each other, there has been a disadvantage that the RAM data is rewritten. According to the configuration, in the configuration in which the control unit and the data storage unit that can read and write data used by the control unit are separately mounted, it is ensured that the data in the data storage unit is rewritten after a power failure. Can be prevented. That is, when the condition for stopping the power supply to the gaming machine is satisfied, the setting of the terminal that outputs the notification signal by the input / output setting means is changed from the setting as the output terminal to the setting as the input terminal, thereby Since the function of outputting the notification signal to the storage means is forcibly disabled, the notification signal is output to the data storage means even when the voltage is unstable such as when the power supply is stopped. As a result, the data in the data storage means can be reliably prevented from being rewritten.

  The data storage means is provided separately from the control means as long as the data storage means and the control means are not provided on the same chip, and the data storage means and the control means are the same. It may be mounted on a substrate, or may be mounted on a different substrate.

  Further, the control means may be one that controls the game itself, or may be one that controls production or the like in relation to the control of the game.

(B) In the slot machine of (a), the control means (main control unit 41)
Control before the power supply stops when the power supply to the gaming machine is started, based on the data stored in the data storage means (SRAM 50) and the control state of the control means (main control unit 41) Return determination means for determining whether it is possible to return to the state (whether the backup data is normal);
After the power supply to the gaming machine is started, before the determination by the return determination means, the input / output setting means sets the terminal for outputting the notification signal (chip select signal) to the input terminal (input Power supply start-time terminal setting changing means for changing the setting to be the output terminal (output terminal) to the setting to be the output terminal (output terminal).

  According to such a configuration, the function of outputting the notification signal to the data storage unit is disabled until the return determination unit determines whether or not the return can be performed. It is possible to prevent the data in the data storage means from being rewritten in a stable state.

(C) In the slot machine of (a) or (b), the control means (main control unit 41) includes:
Performing control related to the game according to a plurality of program modules having different functions,
Backup processing (power interruption processing) for storing backup data in the backup area of the data storage means (SRAM 50) for each program module based on the data used in the program module when the power supply stop condition is satisfied Including backup processing means for
The backup processing means sets a start address so as to be stored in a different backup area for each program module, and stores backup data in a backup area from a storage area corresponding to the set start address.

  According to such a configuration, it becomes possible to complete the backup processing for each function of the gaming machine, and it becomes possible to develop a program related to the backup processing separately for each function. At the same time, the program can be simplified and the development man-hours of the program can be reduced. In addition, the backup process can be simplified.

  (D) In the slot machine of (c), the backup processing means determines, for each program module, whether or not the backup data is normal using data used in the program module. Create check data (checksum).

  According to such a configuration, the program development man-hours can be reduced even if the backup process is performed by a common method regardless of the model by using a program structure composed of a plurality of program modules.

(E) In the slot machine of (c) or (d), for each program module, determination means for determining whether backup data based on data used in the program module is normal;
And return means for performing return processing based on the backup data on condition that all backup data is determined to be normal.

  According to such a configuration, even if the start address is specified so that the start address of the data creation area of the backup data differs for each program module, the return process can be performed reliably.

  (F) In any one of the slot machines (c) to (e), the backup processing means is a common data conversion process (regardless of which program module is the backup data based on the data used). A process of converting 8-bit data into 16-bit data) is performed and the backup data is stored in the backup area.

According to such a configuration, the number of program development steps can be reduced.
(G) In any one of the above slot machines (c) to (f), the program module includes a game control program module (AT control module) for performing processing related to game control (AT),
The backup processing means performs backup processing of backup data based on data used in the game control program module in preference to a program module (image control module) other than the game control program module.

  According to such a configuration, it is possible to reliably back up a highly important program module related to the player's profit.

  It should be noted that priority is given to program modules other than the game control program modules as long as backup processing is performed with priority over at least one of the game control program modules.

It has been established. In this embodiment, only one winning line is applied, but a plurality of winning lines may be applied.

  In the present embodiment, invalid lines LM1 to LM1-4 are set apart from the winning line LN in order to make it easy to recognize that the winning line LN has a combination of symbols constituting the winning line. The invalid lines LM1 to LM4 are not determined based on the combination of symbols aligned with the invalid lines LM1 to LM4. When the combination of symbols constituting a specific prize is arranged on the winning line LN, the invalid line LM1 to LM4. When a combination of symbols (for example, bell-bell-bell) is awarded when the winning line LN is aligned with any of the LM1 to LM4, the symbols constituting the particular winning line LN It is easy to recognize that the combination is complete.

  In this embodiment, as shown in FIG. 1, an invalid line LM1 and a lower stage of the reel 2L, which are set across the symbols arranged horizontally in the upper stage of the reel 2L, the upper stage of the reel 2C, the upper stage of the reel 2R, that is, the upper stage. , The lower stage of the reel 2C, the lower stage of the reel 2R, that is, the invalid line LM2 set across the symbols arranged horizontally in the lower stage, the upper stage of the reel 2L, the middle stage of the reel 2C, the lower stage of the reel 2R, that is, the lower side There are four types of invalid lines LM3 set across straddling symbols LM3, lower stage of reel 2L, middle stage of reel 2C, upper stage of reel 2R, that is, invalid line LM4 set straddling to the right. It is defined as.

  When the start switch 7 is operated in a state where the game can be started, the reels 2L, 2C, and 2R rotate, and the symbols of the reels 2L, 2C, and 2R continuously vary. When any one of the stop switches 8L, 8C, 8R is operated in this state, the rotation of the corresponding reels 2L, 2C, 2R is stopped, and the display result is derived and displayed on the fluoroscopic window 3.

  Then, when all the reels 2L, 2C and 2R are stopped, one game is finished, and a combination of symbols (hereinafter also referred to as a combination) predetermined on the winning line LN is a display result of each reel 2L, 2C and 2R. In the case of a stop, a winning occurs, and a predetermined number of medals are awarded to the player and added to the credit. Further, when the credit reaches the upper limit number (50 in this embodiment), medals are paid out directly from the medal payout opening 9 (see FIG. 1). In addition, when the combination of symbols accompanying the transition of the gaming state is stopped as a display result of each reel 2L, 2C, 2R on the winning line LN, the gaming state is shifted according to the combination of symbols.

  In the slot machine 1 according to the present embodiment, after the game is started and the reels 2L, 2C, and 2R are rotated and the symbols start to change, any one of the stop switches 8L, 8C, and 8R is operated. When this is done, the rotation of the reels corresponding to the stop switches 8L, 8C, 8R is stopped, and the symbols are stopped and displayed. The maximum stop delay time from the operation of the stop switches 8L, 8C, 8R to the stop of the rotation of the corresponding reels 2L, 2C, 2R is 190 ms (milliseconds).

  The reels 2L, 2C and 2R rotate 80 times per minute, and 80 × 21 (the number of symbols per reel) = 1680 frames, so the maximum of 4 symbols is drawn in 190 ms. Will be able to. In other words, the symbols that can be selected as the stop symbols are the symbols that are displayed when the stop switches 8L, 8C, and 8R are operated, and the symbols that are four frames ahead of them, for a total of five symbols.

  For this reason, for example, when any one of the stop switches 8L, 8C, 8R is operated and the symbol displayed on the lower stage of the reel corresponding to the stop switch is used as a reference, the symbol from the symbol to four frames ahead is used. Since the symbols can be displayed in the lower row, in each of the reels 2L, 2C, 2R, when any one of the stop switches 8L, 8R is operated, the symbol displayed in the middle row of the reel corresponding to the stop switch. Can be displayed on the winning line LN.

A detection circuit 48 and a reset circuit 49 are mounted.

  The main control unit 41 is configured by a one-chip microcomputer and includes a main CPU 41a, a ROM 41b, a RAM 41c, and an I / O port 41d. The main control unit 41 executes a control program stored in the ROM 41b to perform processing related to the progress of the game, and directly or indirectly controls each part of the control circuit mounted on the game control board 40. In this embodiment, the main control unit 41 can only perform 16-bit or 32-bit bus access to an external device such as the SRAM 50.

  The random number generation circuit 42 is configured by a counter that counts up and updates the value every time a predetermined number of pulses are generated, and the sampling circuit 43 acquires the numerical value counted by the random number generation circuit 42. The random number generation circuit 42 defines a range of numerical values to be counted for each type of random number. In this embodiment, 0 to 65535 is defined as the range. The main CPU 41a sends an instruction to the sampling circuit 43 according to the processing to acquire the numerical value indicated by the random number generation circuit 42 as a random value (hereinafter, this function is referred to as a hardware random number function). Random numbers for internal lottery, which will be described later, are processed by software instead of using the random numbers extracted by the hardware random number function as they are. The main CPU 41a also has a function of updating a specific register value by the above-described timer interrupt process (main) and acquiring the updated numerical value as a random number (this function is hereinafter referred to as a software random number function). .

  The switch detection circuit 44 takes in detection signals input from switches connected directly to the game control board 40 or via the power supply board 101 and transmits them to the main control unit 41. The motor drive circuit 45 transmits the motor drive signal output from the main control unit 41 to the reel motors 32L, 32C, and 32R. The solenoid drive circuit 46 transmits the solenoid drive signal output from the main control unit 41 to the flow path switching solenoid 30. The LED drive circuit transmits the LED drive signal output from the main control unit 41 to various displays and LEDs connected to the game control board 40. The power interruption detection circuit 48 monitors the power supply voltage supplied to the slot machine 1 and outputs a voltage drop signal indicating that to the main control unit 41 when a voltage drop is detected. The reset circuit 49 gives a reset signal to the main control unit 41 in a state where the power supply is unstable, such as when the power is turned on or when the power is turned off.

  The CPU 41a of the main control unit 41 executes processing for controlling the progress of the game in the slot machine 1 by executing the program read from the ROM.

  As described above, in the main control unit 41, the CPU 41a executes control according to the program stored in the ROM 41b, so that the main control unit 41 (or CPU 41a) executes (or performs processing) hereinafter. Specifically, the CPU 41a executes control according to a program. The same applies to microcomputers mounted on boards other than the game control board 40.

  The RAM 41c included in the main control unit 41 provides a work area for game control and is used as a work RAM. In this embodiment, as will be described later, an SRAM 50 is connected to the main control unit 41 as an external memory, and this SRAM 50 is a backup RAM that is at least partially backed up by a backup power source. That is, even if the power supply to the slot machine is stopped, at least a part of the contents of the SRAM 50 is stored for a predetermined period. In this embodiment, all areas of the SRAM 50 are backup RAMs, and all contents of the SRAM 50 are stored for a predetermined period even when power supply to the slot machine is stopped. In this embodiment, the SRAM 50 serving as the backup RAM includes, for example, data used for control related to internal lottery, which will be described later, data used for control related to medal payout, and reel rotation and stop when power is cut off. Data used for control related to the command, data used for control related to command input / output, and the like are stored.

  The ROM 41a included in the main control unit 41 stores various selection data and table data used for controlling the progress of the game. For example, the ROM 41b stores data constituting a plurality of determination tables, determination tables, setting tables and the like prepared for the CPU 41a to perform various determinations, determinations, and settings. The ROM 41b stores table data constituting a plurality of command tables used for the CPU 41a to transmit control signals serving as various control commands from the game control board 40.

  The RAM 41c included in the main control unit 41 is provided with a game control data holding area as an area for holding various data used for controlling the progress of the game in the slot machine 1 and the like. For example, a DRAM is used as the RAM 41c, and a refresh operation is required to maintain the stored data contents. The CPU 41a has a built-in refresh register for performing this refresh operation. For example, the refresh register has 8 bits, and the lower 7 bits are automatically incremented every time the CPU 41a fetches an instruction from the ROM 41b. Accordingly, the stored value in the refresh register is updated every execution time of one instruction in the CPU 41a.

  The main control unit 41 transmits various commands to the sub control unit 91. A command transmitted from the main control unit 41 to the sub control unit 91 is sent in only one direction, and no command is sent from the sub control unit 91 toward the main control unit 41.

  The main control unit 41 receives the detection state of various switches connected to the game control board 40 from the input port. Then, the main control unit 41 executes basic processing that shifts in stages according to the detection states of various switches input from these input ports.

  Further, the main control unit 41 can execute an interrupt process by interrupting the basic process when an interrupt occurs. In the present embodiment, a timer interrupt process (main) described later is executed at regular time intervals (in the present embodiment, about 0.56 ms). In addition, the execution interval of the timer interrupt process (main) is set to a time longer than the sum of the time required to complete the repeated process according to the control state in the basic process and the execution time of the timer interrupt process (main) Therefore, the process that is repeated according to the control state between the current and next timer interrupt processes (main) is completed at least once.

  The main control unit 41 is set to prohibit other interrupts during the execution of the interrupt process, and when a plurality of interrupts occur at the same time, the main control unit 41 prioritizes according to a predetermined order. An interrupt to be executed is set. If another interrupt factor occurs during the execution of the interrupt process and the interrupt factor continues even after the interrupt process is completed, a new interrupt will occur at that point. It will be.

  An effect switch 56 is connected to the effect control board 90, and a detection signal of the effect switch 56 is input.

  The effect control board 90 is connected to effect devices such as a liquid crystal display 51 (see FIG. 1), an effect LED 52, speakers 53 and 54, and the reel LED 55 described above, which are arranged on the front door 1b of the slot machine 1. These effect devices are driven based on control by a later-described sub-control unit 91 mounted on the effect control board 90.

  In this embodiment, the sub-control unit 91 mounted on the effect control board 90 controls the output of the effect devices such as the liquid crystal display 51, effect effect LED 52, speakers 53 and 54, and reel LED 55. However, in addition to the sub-control unit 91, an output control unit that directly controls the output of the effect device is mounted on the effect control board 90 or another board, and the sub-control unit 91 is based on a command from the main control unit 41. The output control unit may determine the output pattern of the effect device, and the output control unit may control the output of the effect device based on the output pattern determined by the sub control unit 91. In such a configuration, the sub control unit 91 and the output control may be performed. The output control of the rendering device is performed by both of the units.

  Further, in the present embodiment, the liquid crystal display 51, the effect effect LED 52, the speakers 53 and 54, and the reel LED 55 are exemplified as the effect device, but the effect device is not limited to these, for example, a mechanically driven display. A device or a mechanically driven item may be applied as the effect device.

  Like the main control unit 41, the effect control board 90 includes a sub CPU 91a, a ROM 91b, a RAM 91c, and a microcomputer having an I / O port 91d. The sub control unit 91 controls the effect, and an external memory (SRAM). 99, a display control circuit 92 that performs display control of the liquid crystal display 51 connected to the effect control board 90, an LED drive circuit 93 that controls the drive of the effect LED 52 and the reel LED 55, and audio output control from the speakers 53 and 54 A sound output circuit 94 for performing a reset operation, a reset circuit 95 for providing a reset signal to the sub CPU 91a when the power source is unstable, such as when the power is turned on or off, or when an initialization command from the sub CPU 91a is not input for a certain period of time, effect control A detection signal input from the effect switch 56 connected to the substrate 90 is detected. The switch detection circuit 96, the clock device 97 that outputs time information including date information and time information, and the power supply voltage supplied to the slot machine 1 are monitored, and when a voltage drop is detected, a voltage drop signal indicating that is provided. The power interruption detection circuit 98 that outputs to the sub CPU 91a, other circuits, and the like are mounted, and the sub CPU 91a receives various commands from the game control board 40 and performs various controls for performing effects. While performing, it controls each part of the control circuit mounted in the production | presentation control board 90 directly or indirectly. In this embodiment, the sub-control unit 91 can only perform 16-bit or 32-bit bus access to an external device such as the SRAM 99.

  The reset circuit 95 has a lower voltage for canceling the reset signal to the sub CPU 91a than the reset circuit 49 for giving the reset signal to the main CPU 41a of the main control unit 41 in the game control board 40, and the sub control unit when the power is turned on. 91 is activated at an earlier stage than the main control unit 41. On the other hand, the power interruption detection circuit 98 has a voltage that outputs a voltage drop signal lower than the power interruption detection circuit 48 that outputs a voltage drop signal to the main control unit 41 in the game control board 40. The sub control unit 91 detects a power failure at a later stage than the main control unit 41, and performs a power interruption process (sub) described later.

  Similar to the main control unit 41, the sub control unit 91 has an interrupt function, generates an interrupt when receiving a command from the main control unit 41, and acquires a command transmitted from the main control unit 41. Execute command reception interrupt processing to be stored in the buffer. Further, the sub control unit 91 executes an interrupt process (sub), which will be described later, by generating an interrupt every time the number of input system clocks reaches a certain number, that is, every certain interval.

  Also, unlike the main control unit 41, the sub control unit 91 interrupts the process even when the timer interrupt process (sub) is being executed when an interrupt is generated based on the reception of the command. The command reception interrupt process is executed at the same time, and the command reception interrupt process is executed with the highest priority even if interrupts that trigger the timer interrupt process (sub) occur at the same time.

  The RAM 91c included in the sub control unit 91 provides a work area for various effects control such as liquid crystal display, lamp display, and sound output, and is used as a work RAM. In this embodiment, as will be described later, an SRAM 99 is also connected to the sub-control unit 91 as an external memory, and this SRAM 99 is a backup RAM that is at least partially backed up by a backup power source. That is, even if the power supply to the slot machine is stopped, at least a part of the contents of the SRAM 99 is stored for a predetermined period. In this embodiment, all areas of the SRAM 99 are used as a backup RAM, and even if the power supply to the slot machine is stopped, all contents of the SRAM 99 are stored for a predetermined period. In this embodiment, the SRAM 99 serving as a backup RAM includes, for example, data used for control related to sound and LED, data used for control related to AT, and control related to image display when power is cut off. Stores data to be used.

  As shown in FIG. 5A, the main control unit 41 and the SRAM 50 include a 16-bit address bus, a 32-bit data bus, a CS (chip select) signal line, an RD (read) signal line, and a WR (write). Connected via signal line.

  Here, the input / output state of signals when the main control unit 41 reads data from the SRAM 50 and writes data from the main control unit 41 to the SRAM 50 will be described.

  When the main control unit 41 reads data from the SRAM 50, as shown in FIG. 5B, the main control unit 41 designates an address at which data to be read from the SRAM 50 is stored on the address bus, and then The CS signal corresponding to the SRAM is turned ON, and the RD signal for instructing data reading is turned ON.

  The SRAM 50 that has detected the CS signal and the RD signal uses the data bus until the data stored in the address area designated by the address bus is turned off until the RD signal is turned off, that is, until the data fetching by the main control unit 41 is completed. Output to. On the other hand, the main control unit 41 turns off the RD signal by completing the data take-in from the data bus, and then turns off the CS signal and completes the reading of data from the SRAM 50.

  When the main control unit 41 writes data to the SRAM 50, as shown in FIG. 5C, the address where the data is stored is specified by the address bus and the data to be written to the SRAM 50 is output to the data bus. Thereafter, the CS signal corresponding to the SRAM is turned ON, and the WR signal for instructing data writing is turned ON.

  The SRAM 50 that has detected the CS signal and the WR signal fetches data from the data bus and writes the fetched data in the address area designated by the address bus. After that, the main control unit 41 turns off the WR signal and turns off the CS signal corresponding to the SRAM and writes the data to the SRAM 50 after a sufficient time has elapsed for the SRAM 50 to take in the data from the data bus. To complete.

  The sub-control unit 91 and the SRAM 99 are also connected via a 16-bit address bus, a 32-bit data bus, a CS (chip select) signal line, an RD (read) signal line, and a WR (write) signal line. 5B and 5C, the main control unit 41 reads data from the SRAM 50 and writes data from the main control unit 41 to the SRAM 50, and the sub control unit 91 reads data from the SRAM 99. Data reading and data writing from the sub-control unit 91 to the SRAM 99 are performed.

  In the slot machine 1 of the present embodiment, the medal payout rate changes according to the set value. Specifically, the medal payout rate is changed by using a winning probability corresponding to a set value in an internal lottery described later. The set value is composed of 6 levels of 1 to 6, with 6 being the highest payout rate and the payout rate being lower as the value is decreased in the order of 5, 4, 3, 2, 1. That is, when 6 is set as the set value, the advantage is highest for the player, and as the value decreases in order of 5, 4, 3, 2, 1, the advantage decreases stepwise.

  In order to change the setting value, it is necessary to turn on the power of the slot machine 1 after the setting key switch 37 is turned on. When the setting key switch 37 is turned on and the power is turned on, the setting value read from the RAM 41c is displayed as a display value on the setting value display 24, and the setting value can be changed by operating the reset / setting switch 38. Transition to the setting change state. When the reset / setting switch 38 is operated in the setting change state, the display value displayed on the setting value display 24 is updated one by one (when further operation is performed from the setting 6, the display returns to the setting 1). . When the start switch 7 is operated, the display value is determined as the set value. When the setting key switch 37 is turned off, the determined display value (setting value) is stored in the RAM 41c of the main control unit 41, and the state shifts to a state in which the game can proceed.

  In order to check the set value, after the game is over, the setting key switch 37 may be turned on in a state where the bet amount is not set. When the setting key switch 37 is turned on in such a situation, the setting value read out from the RAM 41c is displayed on the setting value display 24, thereby shifting to a setting confirmation state in which the setting value can be confirmed. In the setting confirmation state, the game cannot be progressed, and by setting the setting key switch 37 to the off state, the setting confirmation state is ended and the state in which the game can proceed is returned.

  In the slot machine 1 of the present embodiment, each time the main control unit 41 and the sub control unit 91 execute the timer interrupt process (main) shown in FIG. 12 or the timer interrupt process (sub) shown in FIG. When a power failure determination process (Sk2 in FIG. 12 or Sp2 in FIG. 25) is performed to determine whether or not a voltage drop signal from the power failure detection circuit 48 is detected, and a voltage drop signal is detected in the power failure determination process When the determination is made, the power interruption process (main) shown in FIG. 14 and the power interruption process (sub) shown in FIG. 36 are executed. In the power interruption process (main) and the power interruption process (sub), as described later, a backup flag is set in the SRAM 50 for each program module, and data used in the program module is calculated to generate a checksum. The generated checksum is stored in the SRAM 50. The checksum is a value stored in each bit of a corresponding area of the RAM 41c or RAM 91c (in this embodiment, all areas in the work RAM in which data used by the program module is stored). It is a value calculated as the exclusive OR of. For this reason, if the value obtained by calculating the exclusive OR based on the data stored in all areas in the work RAM in which the data used by the program module is stored is 0, the checksum is 0. If the value obtained by calculating the exclusive OR based on the data stored in all the areas in the work RAM in which the data used in the program module is stored is 1, the checksum is 1.

  The main control unit 41 and the sub control unit 91 store data used in the program module in the external memory (backup RAM) for each module, regardless of whether the system reset or the user reset is performed. Calculate the checksum based on the data of all the stored areas, check the backup flag, check that the calculated checksum matches the checksum value being backed up, and that the backup flag is also set. Based on the data stored in the SRAM 50 as a condition, the processing state of the main control unit 41 and the sub control unit 91 is restored to the state before the power interruption, but the checksum value does not match or the backup flag is set. If not, it is determined that the RAM is abnormal. At this time, if the main control unit 41 determines that the RAM is abnormal, the RAM abnormal error code is set in the register and controlled to a RAM abnormal error state to disable the progress of the game. Unlike the normal error state, the RAM abnormal error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated, and a new set value is set in the above-described setting change state. It will not be released until On the other hand, when the sub control unit 91 determines that the RAM abnormality error has occurred, all the areas of the SRAM 99 and the RAM 91c are initialized.

  In this embodiment, all the data stored in the RAM 41c and RAM 91c are stored in the SRAM 50 and SRAM 99 and maintained by the backup power source even during a power failure, and the main control unit 41 and the sub control unit 91 The data stored in the RAM 41c and the RAM 91c is configured to return to the control state before the power interruption based on the data stored in the SRAM 50 and the SRAM 99 when it is determined that the data in the SRAM 50 and the SRAM 99 is normal at the time of turning on. Of these, only the data necessary for the return of the control state at the time of a power failure may be backed up in the SRAM 50 and SRAM 99, and the control state before the power interruption may be restored based on the backed up data when the power is turned on.

  In addition, when returning to the control state before the power interruption when the power is turned on, it is not necessary to return all the control states to the control state before the power interruption, and the minimum control state that does not disadvantage the player For example, it is not necessary to restore the state of all input ports to the state before power interruption.

  In the slot machine 1 of this embodiment, as described above, the prescribed number of bets that can be set according to the gaming state (usually inside, BB (RB)) is determined, and is determined according to the gaming state. The game can be started on the condition that the specified number of bets has been set. In the present embodiment, the winning line LN is activated when a specified number of bets according to the gaming state are set.

  In the slot machine 1 of this embodiment, when all the reels 2L, 2C, and 2R are stopped, the activated winning line LN (hereinafter, the activated winning line LN is simply referred to as the winning line LN). A winning combination will be awarded when a combination of symbols called roles is complete. The combination may be a combination of the same symbols or a combination including different symbols. The type of winning combination is determined according to the game state, but it can be roughly divided into a small role with payout of medals and a replay that allows the next game to be started without the need to set the number of bets. There are a game combination and a special combination with a transition to a game state advantageous to the player. Below, a small role and a re-playing role are collectively called a general role. In order for winning of each combination determined according to the gaming state to occur, it is necessary to win an internal lottery to be described later and set a winning flag of the combination in the RAM 41c.

  Of the winning flags for each of these combinations, the winning flag for the small role and the re-playing role is valid only in the game in which the flag is set, and is invalid in the next game. It is valid until the combination of combinations permitted by the flag is complete, and is invalid in a game having the combination of combinations permitted. In other words, once the winning flag for a special role is won, even if the combination of characters allowed by the flag cannot be aligned, the winning flag is not invalidated and carried over to the next game. It becomes.

  In the internal lottery, it is determined whether or not the above winning combination is permitted before the display results of all the reels 2L, 2C, and 2R are derived and displayed (actually, when the start switch 7 is detected). To do. In the internal lottery, first, a random value for internal lottery (an integer from 0 to 65535) is acquired when the start switch 7 is detected. Specifically, the value of the random number value storage work assigned to the RAM 41c is set to the lottery work assigned to the RAM 41c. Then, for each combination determined according to the gaming state and whether or not the special combination is carried over, the numerical data stored in the lottery work, the value of the gaming state flag for specifying the gaming state, and the RT described later are specified. The determination is made according to the number of determination values of each combination determined according to the value of the RT flag, the number of bets, and the set value.

  In the internal lottery, an internal lottery target, a current gaming state flag value, an RT flag value, and the number of determination values determined corresponding to the set value are stored in a random number for internal lottery (a lottery work). When the result of addition overflows, it is determined that the winning combination is won. For this reason, a winning combination will be won with a probability (number of determination values / 65536) according to the number of determination values.

  If a winning combination of any combination is determined, a winning flag corresponding to the combination determined to be winning is set in the internal winning flag storing work assigned to the RAM 41c. The internal winning flag storage work consists of a 2-byte storage area, of which the upper byte is assigned as the special role storing work in which the winning flag for the special role is set, and the lower byte is the winning of the general role It is assigned as a general role storage work for which a flag is set. Specifically, when a special combination is won, a special combination winning flag indicating that the special combination is won is set in the special combination storing work, and the winning flag set in the general combination storing work is cleared. When a general combination is won, a winning flag for the general combination indicating that the general combination is won is set in the general combination storing work. If no winning combination is selected, only the general winning combination work is cleared.

Next, stop control of the reels 2L, 2C, 2R will be described.
The main control unit 41 refers to the table index and table creation data stored in the ROM 41b when the reel starts to rotate and when the reel stops and the reel that is still rotating still remains. A stop control table is created for each reel that is rotating. When any of the stop switches 8L, 8C, and 8R corresponding to the rotating reel is effectively detected, the stop control table of the corresponding reel is referred to and the slip of the referred stop control table is referred to. Based on the number of frames, control is performed to stop the rotation of the reels 2L, 2C, 2R corresponding to the operated stop switches 8L, 8C, 8R.

  In the table index, an index that indicates the start address of the area in which the data for table creation is stored, from the reference address when referring to the table index, according to the setting state of the winning flag by internal lottery (hereinafter referred to as the internal winning state) Differences up to the address where the data is stored are registered. As a result, a difference corresponding to the internal winning state is acquired, and the corresponding index data can be acquired by adding the difference to the reference address. Even when the winning combinations are different, when the same control is applied, the same address is stored as the index data. In such a case, the same table creation data is referred to. Thus, a stop control table is created.

  The table creation data includes a stop control table indicating the number of sliding frames according to the stop operation position, and an address of the stop control table to be referred to according to the reel stop status.

  The stop control table referred to according to the reel stop status is whether all reels are rotating, only the left reel is stopped, only the middle reel is stopped, only the right reel is stopped, It may vary depending on whether the middle reel is stopped, the left and right reels are stopped, the middle and right reels are stopped, and if any reel is stopped, stop Since there may be differences depending on the stop position of the reels already completed, the address of the stop control table to be referenced for each situation is registered for each rotating reel, and based on the top address of the table creation data, It is possible to specify the address of the stop control table that should be referred to according to the status of each, and it is necessary according to each status from this specified address. And to be able to identify the stop control table. Even when the reel stop status and the stopped position of the stopped reel are different, when the same stop control table is applied, the same address may be registered as the address of the stop control table. In such a case, the same stop control table is referred to.

  The stop control table is data that can specify the number of sliding frames for each timing when the stop operation is performed. In this embodiment, stepping motors that make one turn at a cycle of 168 steps (0 to 167) are used for the reel motors 32L, 32C, and 32R. That is, when the reel motors 32L, 32C, and 32R are driven for 168 steps, the reels 2L, 2C, and 2R make one round. 21 areas (frames) divided every 8 steps (the number of steps in which one symbol moves) per reel are defined, and these areas are areas 0 to 20 from the reel reference position. A number is assigned. On the other hand, the number of symbols arranged on one reel is 21, and symbol numbers 0 to 20 from the reel reference position are assigned to symbols on each reel, so symbols 0 to 20 are assigned to each reel. , Area numbers 0 to 20 are assigned in order. In the stop control table, the number of sliding symbols for each area number is compressed and stored according to a predetermined rule, and the number of sliding symbols for each area number can be acquired by expanding the stop control table. Yes.

  As described above, the stop control table created by referring to the table index and the table creation data corresponds to the area number, and the area corresponding to each area number is the stop reference position (in this embodiment, the perspective window 3). Sliding frame when an operation of the stop switches 8L, 8C, 8R is detected at a timing (a timing in which the number of steps from the reel reference position is included in the range of the number of steps of each region number). It is a table with each number set.

  Next, the procedure for creating the stop control table will be described. First, at the start of reel rotation, the top address of the table creation data corresponding to the internal winning state of the game is acquired. Specifically, the table index is first referred to, index data corresponding to the internal winning state is obtained, table creation data is identified based on the obtained index data, and all reels are identified from the identified table creation data. The address of the stop control table for each reel corresponding to the state of rotation is acquired, and the stop control table for each reel stored at the acquired address is expanded to generate a stop control table for all reels.

  Further, when any one reel stops or any two reels stop, the index data acquired at the start of reel rotation, that is, the top address of the table creation data corresponding to the internal winning state of the game The table creation data is identified based on the table creation data, and the stop control table address of the unreacted reel corresponding to the stopped reel and the area number of the stop position of the reel is obtained from the identified table creation data. The stop control table for each stored reel is expanded to create a stop control table for the unstopped reels.

  Next, when the main control unit 41 effectively detects any one of the stop switches 8L, 8C, and 8R corresponding to the rotating reel, the control when the display result is derived to the corresponding reel is described. To explain, when any operation corresponding to the rotating reel is detected effectively among the stop switches 8L, 8C, 8R, the stop operation position is based on the number of steps from the reel reference position when the stop operation is detected. The number of sliding symbols corresponding to the area number of the specified stop operation position is acquired by referring to the stop control table of the reel where the stop operation is detected. Then, control is performed to rotate and stop the reel by the number of acquired sliding frames. Specifically, from the number of steps from the reel reference position at the time when the stop operation is detected, the number of steps from the acquired number of sliding frames to the stop is calculated, and the reel is rotated and stopped by the calculated number of steps. Take control. As a result, the area corresponding to the area number that is the stop position ahead of the number of sliding frames from the area corresponding to the area number of the stop operation position where the stop operation is detected is the stop reference position (in this embodiment, the perspective window 3 It will stop in the lower symbol area).

  In the table index of this embodiment, only one address is stored as index data corresponding to one internal winning state in one gaming state, and further, one table creation data includes one reel. Only one address is stored as the address of the storage area of the stop control table corresponding to the stop status (and the stop position of the stopped reel). In other words, table creation data corresponding to one internal winning state in one gaming state and stop control tables corresponding to reel stop states (and stopped positions of stopped reels) are uniquely determined. The stop control table created with reference to is unique for one internal winning state in one gaming state and the reel stop status (and the stop position of the stopped reel). Therefore, when all of the gaming state, the internal winning state, and the reel stop status (and the stop position of the stopped reel) are the same, the reel is based on the same stop control table, that is, the same control pattern. The stop control is performed.

  Further, in this embodiment, a value of 0 to 4 is determined as the number of sliding frames, and it is possible to stop the reel by drawing a maximum of 4 symbols after detecting a stop operation. That is, the symbol stop position can be designated from a range of up to five frames including the stop operation position at which the stop operation is detected. In addition, since it is necessary to move one frame to move the reel for one symbol, it is possible to stop the reel by pulling in a maximum of four symbols after detecting the stop operation. The symbol stop position can be designated from a range of up to five symbols including the operation position.

  In the present embodiment, when any winning combination is won, the winning combination is drawn to the winning line LN to the maximum extent within a range of 4 frames, and the winning combination is drawn so that the winning combination is not aligned with the winning line LN. A stop control table with a defined number of frames is created and reel stop control is performed. If no winning combination is selected, a stop control table with a determined number of sliding symbols that do not have any combination And stop control of the reel. As a result, when a stop operation is performed, if the winning combination can be stopped in the winning line LN within the drawing range of a maximum of 4 frames, the control is performed so that the winning combination is stopped. The combination that has not been performed will be controlled to be stopped in a drawing range of up to 4 frames.

  If a special role and a small role are elected at the same time, such as when a special role is elected while the special role has been carried over from before the previous game, the elected small role will be placed in the winning line LN within 4 frames. The number of sliding symbols is set so as to be pulled in as much as possible, and for the stop operation position where the selected small role cannot be drawn into the winning line LN within the range of up to 4 frames, the winning special role is set to 4 in the winning line LN. A stop control table in which the number of sliding frames is determined so as to be pulled in as much as possible within the range of frames is created, and reel stop control is performed. As a result, when a stop operation is performed, if it is possible to stop all the small roles that have been selected in the winning line LN within a drawing range of a maximum of 4 frames, the control is performed so that the winning combination is stopped. If it is not possible to withdraw a small role that has been won in the draw range of up to 4 frames to the line LN, if the special role that has been won in the draw range of up to 4 frames can be aligned and stopped on the winning line LN, Control is performed to align and stop this, and the winning combination that has not been won is controlled to be stopped within the drawing range of 4 frames. That is, in such a case, priority is given to the control for aligning the small role with the winning line LN over the special role, and the special role can be won only when the small role cannot be drawn. When a special combination and a small combination can be withdrawn at the same time, only the small combination is drawn, and the small combination is not aligned with the winning line LN at the same time as the special combination.

  In this example, when a special role is elected while the special role has been carried over from before the previous game, or when a special role and a small role are simultaneously elected, the special role and the small role are won simultaneously. If the winning combination is prioritized over the selected winning combination, and only when the winning combination cannot be withdrawn, control is performed to align the winning combination with the winning line LN. When winning simultaneously, priority is given to the control for aligning the special combination with the winning line LN over the small combination, and the control for aligning the small combination with the winning line LN may be performed only when the special combination cannot be drawn.

  If a special player and a replaying player are elected at the same time, such as when a replaying player is elected while the special role has been carried over from before the previous game, the winning line LN will be displayed when the stop operation is performed. In addition, a control is performed in which the symbols of the re-gamer are aligned and stopped within a drawing range of up to 4 frames. In this case, the symbols constituting the re-gamer or the symbols constituting the re-gamer to be simultaneously elected are arranged at intervals of 5 symbols or less, that is, within 4 frames, for any of the reels 2L, 2C, and 2R. Since it can always be stopped at any position within the 4-frame pull-in range, if the special combination and the re-playing combination are elected at the same time, the timing of the operation of the stop switches 8L, 8C, 8R by the player Without fail, the re-playing role will always be won. That is, in such a case, the control for aligning the re-games with the winning line LN has priority over the special game, and the re-games will always win. In the case where the special combination and the re-playing combination can be withdrawn at the same time, only the re-playing combination is drawn in and the special combination is not aligned with the winning line LN at the same time as the re-playing combination.

  In this embodiment, after the rotation of the reels 2L, 2C, and 2R is started, the main control unit 41 rotates the reels for which the stop operation has not been detected yet until the operation of the stop switches 8L, 8C, and 8R is detected. Continuously, on the condition that the operation of the stop switches 8L, 8C, and 8R is detected, control is performed to stop the display result on the corresponding reel. Even if the reel rotation temporarily stops due to the occurrence of a reel rotation error, the stop operation is still detected until the operation of the stop switches 8L, 8C, and 8R is detected after the reel rotation is restarted. Control is performed to stop the display result of the corresponding reels on the condition that the rotation of the reels that have not been continued is continued and the operation of the stop switches 8L, 8C, and 8R is detected.

  In this embodiment, control is performed to stop the display result on the corresponding reel on condition that the operation of the stop switches 8L, 8C, and 8R is detected. However, the rotation of the reel is started. When a predetermined automatic stop time has elapsed, even if the reel stop operation is not performed, it is assumed that the stop operation has been performed, and automatic stop control is performed to automatically stop each reel. May be. In this case, since the reels are stopped without the player's operation, for example, it is preferable to derive a display result that does not constitute any combination even if any combination is won.

  As shown in FIG. 6, the game control program is stored in the ROM 41 b of the game control board 41. The game control program includes an internal lottery control module that performs control related to the internal lottery process executed in Sd2 in the game control process of FIG. 11 and an input / output process executed in Sd7 of the game control process of FIG. An input / output control module that performs control related to input / output at the I / O port), a reel rotation control module that performs control related to reel rotation processing executed in Sd3 in the game control processing of FIG. 11, and FIG. A payout control module for performing control related to the payout process executed in Sd5 in the game control process. Thus, the game control program includes a plurality of control modules corresponding to each control executed on the main control board 41. Therefore, only one type of control module (one or more) may be replaced with another type. In this case, only the control module needs to be replaced, and the game control program can be easily changed.

  As shown in FIG. 7, an effect control program is stored in the ROM 91 b of the effect control board 91. The effect control program includes a game history control module that performs control such as accumulation of game history in the game history control process executed at Sp8 in the timer interrupt process (sub) of FIG. 25, and the timer of FIG. In the sound / LED control process executed at Sp5 in the interrupt process (sub), the sound / LED control module for performing control related to the effect LED 52, the speakers 53, 54, and the reel LED 55 described above, and the timer allocation of FIG. In the AT control module that performs control related to the AT control process executed in Sp6 in the interrupt process (sub), and in the image control process that is executed in Sp7 in the timer interrupt process (sub) in FIG. And an image control module for performing control related to image display. Thus, the effect control program includes a plurality of control modules corresponding to each control executed on the effect control board 91. Therefore, only one type of control module (one or more) may be replaced with another type. In this case, only the control module needs to be replaced, and the production control program can be easily changed.

  Next, various control contents executed by the main control unit 41 in the present embodiment will be described below with reference to FIGS.

  When a reset signal is input from the reset circuit 49 to the main CPU 41a, the main control unit 41 performs start-up processing (main) shown in the flowcharts of FIGS.

  First, after the built-in device, peripheral IC, interrupt mode, stack pointer, etc. are initialized (Sa1), the values of the I register and IY register are initialized (Sa2). By the initialization of the I register and the IY register, the address of the interrupt table to be referred to when an interrupt occurs is set in the I register, and the reference address for referring to the storage area of the RAM 41c is set in the IY register. . These values are fixed values and are always initialized at startup. Next, by setting the output of the general-purpose port corresponding to the general-purpose terminal to which the CS signal line connected to the SRAM 50 is connected (Sa3), after enabling the output of the chip select signal of the SRAM 50, the RAM 41c Access to (work RAM) is permitted (Sa4).

  After permitting access to the RAM 41c (work RAM), it is determined whether or not the backup flag for the internal lottery control module is set in the SRAM 50 (backup RAM) (Sa5). In this embodiment, in Sm5, Sm10, Sm15, and Sm20 in the power interruption process (main) of FIG. 14, when a power interruption occurs, a backup flag is set for each program module. That is, in this embodiment, regarding the processing performed by the main control unit 41, the backup flag corresponds to the backup flag corresponding to the internal lottery control module, the backup flag corresponding to the input / output control module, and the reach rotation control module. There are four types of backup flags and backup flags corresponding to the payout control module. In Sa5, the main control unit 41 first checks whether or not a backup flag corresponding to the internal lottery control module is set.

  When the backup flag corresponding to the internal lottery control module is set, the backup flag is cleared (Sa6). After clearing the backup flag, a checksum is calculated by obtaining an exclusive OR of data in an area where data used in the internal lottery control module of the SRAM 50 (backup RAM) is stored (Sa7). Thereafter, it is determined whether or not the calculated checksum matches the backed-up checksum (Sa8). In this embodiment, in Sm4, Sm9, Sm14, and Sm19 in the power interruption process (main) of FIG. 14, the data used in the module is excluded for each module when a power interruption occurs. Is generated by obtaining a logical OR, and stored in the SRAM 50 (backup RAM). That is, in this embodiment, regarding the processing performed by the main control unit 41, the checksum includes a checksum calculated using data used in the internal lottery control module and data used in the input / output control module. There are four types: a checksum calculated using the checksum, a checksum calculated using data used in the reach rotation control module, and a checksum calculated using data used in the payout control module. . In Sa8, the main control unit 41 first confirms whether or not the checksum calculated using the data used in the internal lottery control module matches that being backed up.

  If the checksums match, it is determined whether a backup flag corresponding to the input / output control module is set in the SRAM 50 (backup RAM) (Sa9). If the backup flag corresponding to the input / output control module is set, the backup flag is cleared (Sa10). After clearing the backup flag, a checksum is calculated by obtaining an exclusive OR of data in an area where data used by the input / output control module of the SRAM 50 (backup RAM) is stored (Sa11). Thereafter, it is determined whether or not the calculated checksum matches the backed-up checksum (Sa12).

  If the checksums match, it is determined whether a backup flag corresponding to the reel rotation control module is set in the SRAM 50 (backup RAM) (Sa14). If the backup flag corresponding to the reel rotation control module is set, the backup flag is cleared (Sa15). After clearing the backup flag, the exclusive sum of the data in the area where the data used in the reel rotation control module of the SRAM 50 (backup RAM) is stored is calculated to calculate the checksum (Sa16). Thereafter, it is determined whether or not the calculated checksum matches the backed-up checksum (Sa17).

  If the checksums match, it is determined whether a backup flag corresponding to the payout control module is set in the SRAM 50 (backup RAM) (Sa18). If the backup flag corresponding to the payout control module is set, the backup flag is cleared (Sa19). After clearing the backup flag, the checksum is calculated by obtaining the exclusive OR of the data in the area where the data used by the payout control module of the SRAM 50 (backup RAM) is stored (Sa20). Thereafter, it is determined whether or not the calculated checksum matches the backed-up checksum (Sa21).

  In Sa8, Sa12, Sa17, Sa21, when it is determined that even one checksum does not match, or in Sa5, Sa9, Sa14, Sa18, it is determined that no backup flag is set. In this case, after executing an initialization process for initializing all storage areas of the RAM 41c (work RAM) and the SRAM 50 (backup RAM) (Sa29), it is determined whether the setting key switch 37 is on (Sa30). . If the setting key switch 37 is on, a setting changing command indicating that the setting is being changed is generated, and the generated setting changing command is stored in the command buffer (Sa27). The setting changing command is immediately transmitted by executing the same process as the command transmission process of step Sk16 in the timer interrupt process described later after the process of step Sa27. Next, the main control unit 41 described in FIG. 12 permits the interruption of the timer interruption process (main) executed at regular intervals (0.56 ms interval) (Sa28), and changes the winning probability of the winning combination, etc. The process shifts to a setting change process for performing the setting, that is, a setting change state. When the setting change process is completed, the game control process shown in FIG. 11 is performed.

  If the setting key switch 37 is OFF in the step of Sa30, an error code indicating RAM abnormality is set in the register (Sa31), an error command indicating RAM abnormality is generated, and the generated error command is stored in the command buffer ( Sa32). The error command is transmitted immediately after the process of step Sa32 by executing the same process as the command transmission process of step Sk16 in the timer interrupt process described later. Next, the main control unit 41 described in FIG. 12 permits the interrupt of the timer interrupt process (main) executed at regular intervals (0.56 ms interval) (Sa33), and error processing, that is, the RAM abnormal error state Migrate to Then, for example, when the RAM abnormality error state is canceled by operating the reset / setting switch 38 by a game store clerk, the game control process shown in FIG. 11 is performed.

  If it is determined in Sa21 that the checksums match, it is determined whether or not the setting key switch 37 is on (Sa23). If the setting key switch 37 is on, the initialization process for initializing all storage areas of the RAM 41c (work RAM) and the SRAM 50 (backup RAM) is executed (Sa26), and then the processes of Sa27 to Sa28 described above are performed. , Transition to the setting change process, that is, the setting change state. When the setting change process is completed, the game control process shown in FIG. 11 is performed.

  If the setting key switch 37 is off in the step of Sa23, each register is returned to the state before power interruption, that is, the state stored in the stack (Sa24). Then, a return command is generated, the generated return command is stored in the command buffer (Sa24a), and a timer interrupt process (main interval of 0.56 ms) executed by the main control unit 41 described in FIG. Main) interrupt is permitted (Sa25), and the process executed last before power interruption is returned to. The return command is stored in a command transmission buffer assigned to a special work in the RAM 41c of the main control unit 41, and a process similar to the command transmission process in step Sk16 in the timer interrupt process described later is executed. Sent immediately when power is restored. If any one of the game control processes shown in FIG. 11 has been performed before the power interruption, the game control process Sd1 to Sd7 is executed based on the value of the program counter (PC) restored in Sa24. Return to the processing that was performed before power interruption. Further, for example, if any of the timer interrupt processing shown in FIG. 12 has been performed before power interruption, the timer interrupt is based on the value of the program counter (PC) restored in Sa24. Of the processes Sk1 to Sk26, the process returns to the process performed before power interruption.

  As described above, in the start-up process (main), all the checksums of the program modules match each other and all the backup flags for the program modules are set. Since the previous state is restored, it is possible to prevent the backup data of some modules from being restored even though they are not accurate. Thereby, even if backup data is created for each module, it can be reliably restored.

  Commands transmitted from the main control unit 41 to the sub control unit 91 include an internal winning command, a reel rotation start command, a reel stop command, a winning determination command, a return command, a setting changing command, and an error command.

  The internal winning command is a command indicating a setting state of a winning flag that is set according to a lottery result of an internal lottery performed when the start switch 7 is operated. The reel rotation start command is a command for notifying the start of reel rotation. The reel stop command is a command that can specify whether the reel to be stopped is the left reel, the middle reel, or the right reel, the area number of the corresponding reel stop operation position, and the area number of the corresponding reel stop position. It is. Since the reel stop command is transmitted when the stop switches 8L, 8C, and 8R are operated, it is possible to specify that the stop switches 8L, 8C, and 8R are operated by receiving the reel stop command. . The winning determination command is a command that can specify the presence / absence of winning, the type of winning, and the number of medals to be paid out when winning is determined after the winning determination is made at the end of the game.

  The error command is a command indicating occurrence or cancellation of an error state and the type of error state.

  The return command is a command indicating that the main control unit 41 has returned to the control state before power interruption.

  The setting changing command is a command indicating that the setting is being changed. In addition, since the control state of the main control unit 41 is initialized with the transition to the setting change state, the control state of the main control unit 41 is initialized by a setting changing command indicating that the setting is being changed. Can be specified.

  With respect to the above-described multiple types of commands, when a command for changing settings, an error command, or a return command is transmitted in the startup process shown in FIGS. 8 to 10, these commands are stored in the RAM 41 c of the main control unit 41. Is stored in the command transmission buffer assigned to the special work, and is transmitted immediately in the startup process by executing the same process as the command transmission process in step Sk16 in the timer interrupt process described later.

  On the other hand, an internal winning command, a reel rotation start command, a reel stop command, a winning determination command, etc. are temporarily stored in a command transmission buffer provided in a special work of the RAM 41c of the main control unit 41, as shown in FIG. It is transmitted to the sub-control unit 91 in the command transmission process (Sk16) executed in the timer interrupt process (main).

  FIG. 11 is a flowchart showing the control content of the game control process executed by the main control unit 41.

  In the game control process, a BET process (Sd1), an internal lottery process (Sd2), a reel rotation process (Sd3), a winning determination process (Sd4), a payout process (Sd5), a game end process (Sd6), an input / output process ( When the input / output process (Sd7) is completed, the process returns to the BET process (Sd1) again.

  In the BET process in the step of Sd1, the process waits in a state where a bet number can be set, and a process for starting a game when a specified number of bets is set according to the gaming state and the start switch 7 is operated is executed. .

  The internal lottery process in step Sd2 is a process executed by the main control unit 41 according to the internal lottery module. In the internal lottery process in the step of Sd2, it is determined whether or not the above winning combination is allowed based on the internal lottery random value latched simultaneously with the start of the game by the detection of the start switch 7 in the step of Sd1. Process. In this internal lottery process, a winning flag is set in the RAM 41c based on the respective lottery results.

  The reel rotation process in step Sd3 is a process executed by the main control unit 41 according to the reel rotation control module. In the reel rotation process in the step of Sd3, the process of rotating each reel 2L, 2C, 2R and the operation of the corresponding reel 2L, 2C, 2R in response to the operation of the stop switch 8L, 8C, 8R detected by the player are detected. A process for stopping the rotation is executed. A reel rotation command indicating that the reels 2L, 2C and 2R have started rotating, a reel stop command indicating the type of reel to be stopped, and a symbol to be stopped for the reel are generated in the reel rotation processing and stored in the command buffer. . Each command stored in the command buffer is transmitted to the sub-control unit 91 in the command transmission process (Sk16) executed in the timer interrupt process (main) shown in FIG. Then, it waits until the rotation of the reel (2L, 2C, 2R) corresponding to the operated stop button stops (Sf12).

  In the winning determination process in the step Sd4, when it is determined in the step Sd3 that the rotation of all the reels 2L, 2C, and 2R is stopped, the winning is determined according to the display result derived for each reel 2L, 2C, and 2R. A process of determining whether or not it has occurred is executed.

  The payout process in step Sd5 is a process executed by the main control unit 41 according to the payout control module. In the payout process in step Sd5, when it is determined that a prize is generated in step Sd4, processing such as addition of credits and payout of medals is performed based on the number of payouts according to the win.

  In the game end process in the step of Sd6, a process of setting a gaming state in preparation for the next game is executed.

  The input / output process in step Sd7 is a process executed by the main control unit 41 according to the input / output control module. In the input / output process in step Sd7, the input state of the input port is monitored, the presence / absence of input of various switches is detected, and the detection result is set in the input buffer. In this embodiment, for example, in the switch input determination process of Sk21 in FIG. 13 and the stop switch process of Sk23 in FIG. 13 described later, whether or not each switch is turned on by looking at the state of the input buffer set in Sd7. To check. In the input / output process in step Sd7, a process of outputting output signals to various solenoids and LEDs is performed based on the state of the output buffer. In this embodiment, for example, various output values such as LEDs are set in the output buffer in the LED dynamic display process of Sk12 in FIG.

  12 and 13 are flowcharts showing the control contents of the timer interrupt process (main) executed by the main control unit 41 by interrupting and executing the activation process and the game control process at regular intervals (0.56 ms interval). Note that other interrupts are automatically prohibited during the execution period of the timer interrupt process (main).

  In the timer interrupt process (main), first, the register in use is saved in the stack area (Sk1).

  Next, a power failure determination process is performed (Sk2). In the power failure determination process, it is determined whether or not a voltage drop signal is input from the power failure detection circuit 48. If a voltage drop signal is input, whether or not the voltage drop signal is input in the previous power failure determination process as well. If a voltage drop signal has been input in the previous power failure determination process, it is determined that a power failure has occurred, and a power interruption flag indicating that is set.

  After the power failure determination process in the step of Sk2, it is determined whether or not the power interruption flag is set (Sk3). If the power interruption flag is not set, the process proceeds to Sk4 and the power interruption flag is set The process proceeds to a power interruption process (main) described later.

  In step Sk4, port input processing for inputting detection data of various switches from the input port is performed.

  Next, the branch counter for identifying the timer interrupt to be executed in the timer interrupt process (main) is advanced by 1 from the four types of timer interrupts 1 to 4 (Sk5). In this embodiment, the timer interrupt 1 is a branch process during a timer interrupt that controls the motor to control the start of the reel. Specifically, the processes from Sk9 to Sk11, such as a reel start process described later. Is done. Timer interrupt 2 is a branch process during timer interrupt that performs LED display control, time counter update, door open / close status monitoring, control signal output control, command and external output signal update, etc. Specifically, the processes of Sk12 to Sk17 such as the LED dynamic display process described later are performed. The timer interrupt 3 is a branching process during timer interrupt that detects the origin passage of the reel, monitors the switch input, and reads out the random number value. Processing of Sk20 to Sk22 such as time processing is performed. The timer interrupt 4 is a branching process during a timer interrupt that detects the input of a stop switch and performs reel stop control. Specifically, the processes of Sk23 to Sk25, such as a stop switch process described later. Is done. In the step of Sk5, 1 is added when the branch counter value is 0 to 2, and is updated to 0 when the counter value is 3. That is, the branch counter value loops in the order of 0 → 1 → 2 → 3 → 0... Each time the timer interrupt process (main) is executed.

  Next, the branch counter value is referenced to determine whether it is 2 or 3, that is, timer interrupt 3 or timer interrupt 4 (Sk6). If it is not timer interrupt 3 or timer interrupt 4, that is, timer interrupt In the case of 1 or timer interrupt 2, it is checked whether the reel motors 32L, 32C, 32R are started or whether they are rotating at a constant speed, and whether the reel motors 32L, 32C, 32R are started or are rotating at a constant speed. For example, the motor phase signal output process for outputting the phase signal data changed in the motor step process of Sk10 described later and the phase signal data changed in the final stop process of Sk24 described later is executed (Sk7).

  Next, referring to the counter value for branching, it is determined whether or not it is 1, that is, timer interrupt 2 (Sk8). If it is not timer interrupt 2, that is, timer interrupt 1, the reel motor Reel starting process (Sk9) for controlling the step time interval when starting 32L, 32C, 32R, motor step process (Sk10) for changing phase signal data of the reel motors 32L, 32C, 32R, reel motors 32L, 32C After the stop of 32R, motor phase signal standby processing (Sk11) for changing the phase signal to one-phase excitation after a predetermined time has been sequentially executed, and then the process proceeds to step Sk25.

  In the case of timer interrupt 2 in the step of Sk8, LED dynamic display processing (Sk12) for dynamically lighting various indicators, and output processing of control signals and the like for outputting data such as lighting signals of various LEDs to the output port (Sk13), a time counter update process (Sk14) for updating various time counters, a door monitoring process (Sk15) for monitoring the detection state of the door open detection switch 25, a door command transmission request, etc., set in the command buffer A command transmission process (Sk16) for transmitting various commands such as a setting change command, a return command, and an error command to the sub-control unit 91 and an external output signal update process (Sk17) for updating the external output signal are sequentially executed, and then Sk25. Go to step.

  If it is timer interrupt 3 or timer interrupt 4 in the step of Sk6, it is further determined by referring to the counter value for branching whether it is 3, that is, timer interrupt 4 (Sk18). If it is not interrupt 4, that is, if it is timer interrupt 3, the passing of the origin of the rotating reels 2L, 2C, 2R (pass of the reel reference position) is checked, and the occurrence of a reel rotation error is detected and stopped. Check if the preparation is complete (whether the stop preparation completion code is set). If the stop preparation is complete and the motor is rotating at a constant speed, operate the stop switch corresponding to the rotating reel. Processing to pass through origin (Sk20), switch input determination processing (Sk21) for determining whether or not the detection state of switches has changed, operation detection command transmission request, etc. After executing random number reading process to be stored in the random number storing work the (SK22) sequentially reads numeric data from Staphylococcus R1D, the process proceeds to step Sk26.

  If the timer interrupt is 4 in the step of Sk18, the stop stored in the work on the stop reel is stored when the stop operation position is stored in the work on the stop reel in accordance with the detection of the stop switches 8L, 8C, 8R. The stop position is determined from the operation position, the stop switch process (Sk23) for calculating the number of steps after which the stop should be performed, and the number of steps until the stop calculated in the stop switch process is counted. A stop process (Sk24) for starting braking by two-phase excitation and a final stop process (Sk25) for three-phase excitation after a certain time from the start of braking in the stop process are sequentially executed, and then the process proceeds to step Sk26.

  In the step of Sk26, the register saved in the stack area in Sk1 is restored, and the processing before the interruption is returned.

  As described above, in this embodiment, the timer interrupt process (main) is executed by interrupting the basic process at regular intervals, and the process counter is updated each time the timer interrupt process (main) is executed. In addition to distributing the load required for one timer interrupt process (main), the power interruption condition based on the voltage drop signal regardless of the process counter value. A power failure determination process is performed to determine whether or not the power failure is satisfied.If the power interruption condition is satisfied, the power interruption processing is performed. Disconnection processing can be performed.

  In the timer interrupt process (main), it is determined whether or not the power interruption condition is satisfied. If the power interruption condition is satisfied, the process proceeds to the power interruption process. Since interruptions due to power interruptions do not occur during execution of interrupt processing (main), interruption processing can be interrupted during execution of timer interruption processing (main), or timer interruption processing (main) Since it is not necessary to wait for the end of the interruption to perform an interruption process associated with power interruption, the process associated with establishment of the power interruption condition is not complicated.

  FIG. 14 is a flowchart showing the control contents of the power interruption process (main) executed when the main control unit 41 determines that the power interruption flag is set in the timer interrupt process (main) described above.

  In the power interruption process (main), first, the main control unit 41 reads data used in the internal lottery control module from the work RAM (Sm1). Next, predetermined data conversion is performed on the data read from the work RAM to create backup data (Sm2). Then, the main control unit 41 stores the created backup data in the SRAM 50 (backup RAM) (Sm3). Next, the main control unit 41 calculates the exclusive OR of the backup data converted in Sm2, calculates the checksum of the backup data of the internal lottery control module, and sets this in the SRAM 50 (backup RAM) (Sm4) . After setting the checksum data, the main control unit 41 sets a backup flag indicating that the backup has been executed in the SRAM 50 (backup RAM) (Sm5).

  Here, the data conversion process in step Sm2 will be described. In Sm1, the main control unit 41 reads data of 2 bytes (16 bits) from the work RAM which is an internal memory. In this embodiment, an SRAM 50 capable of only 8-bit bus access is connected as an external memory and used as a backup RAM. As described above, in this embodiment, the main control unit 41 can only perform 16-bit or 32-bit bus access to an external device such as an external memory. Then, even if the 16-bit data read from the work RAM is stored in the SRAM 50 (backup RAM) as it is, only the 8-bit data can be recognized on the SRAM 50 (backup RAM) side, so the upper 8 bits are lost, A situation occurs in which only lower 8-bit data can be stored in the SRAM 50 (backup RAM). Therefore, in the step Sm2, the 16-bit data read in Sm1 is converted into two data by performing the following data conversion process.

  First, for the first conversion data, the 16-bit data read in Sm1 is masked with the mask value “00FF (H)” as it is, and only the lower 8 bits of the original data read in Sm1 are used as the lower 8 bits. Generate data set to. For the second conversion data, the 16-bit data read in Sm1 is shifted by 8 bits (therefore, the value in the upper 8 bits of the original data is moved to the lower 8 bits). ), The data after the shift processing is masked with the mask value “00FF (H)”, and data in which the upper 8 bits of the original data read in Sm1 are set to the lower 8 bits is generated. Then, by storing these two pieces of conversion data in the SRAM 50 (backup RAM) in the step Sm3, the upper and lower values of the original data read in Sm1 are not lost, although they are divided into two data. Can backup power.

  In Sm7, Sm12, and Sm17, which will be described later, the same data conversion process as that in Sm2 described above is executed.

  Next, the main control unit 41 reads data used in the input / output control module from the work RAM (Sm6). Next, predetermined data conversion is performed on the data read from the work RAM to create backup data (Sm7). The main control unit 41 stores the created backup data in the SRAM 50 (backup RAM) (Sm8). Next, the main control unit 41 calculates the exclusive OR of the backup data converted in Sm2, calculates the checksum of the backup data of the input / output control module, and sets it in the SRAM 50 (backup RAM) (Sm9). . After setting the checksum data, the main control unit 41 sets a backup flag indicating that the backup has been executed in the SRAM 50 (backup RAM) (Sm10).

  Next, the main control unit 41 reads data used in the reel rotation control module from the work RAM (Sm11). Next, predetermined data conversion is performed on the data read from the work RAM to create backup data (Sm12). The main control unit 41 stores the created backup data in the SRAM 50 (backup RAM) (Sm13). Next, the main control unit 41 calculates the exclusive OR of the backup data converted in Sm2, calculates the checksum of the backup data of the reel rotation control module, and sets it in the SRAM 50 (backup RAM) (Sm14). . After the checksum data is set, a backup flag indicating that the backup has been executed is set in the SRAM 50 (backup RAM) (Sm15).

  Next, the main control unit 41 reads data used in the payout control module from the work RAM (Sm16). Next, predetermined data conversion is performed on the data read from the work RAM to create backup data (Sm17). The main control unit 41 stores the created backup data in the SRAM 50 (backup RAM) (Sm18). Next, the main control unit 41 calculates the exclusive OR of the backup data converted in Sm2, calculates the checksum of the backup data of the payout control module, and sets it in the SRAM 50 (backup RAM) (Sm19). After setting the checksum data, the main control unit 41 sets a backup flag indicating that the backup has been executed in the SRAM 50 (backup RAM) (Sm20).

  After setting the backup flag in Sm20, access to the RAM 41c is prohibited (Sm21), and the setting of the general-purpose port corresponding to the general-purpose terminal to which the CS signal line connected to the SRAM 50 is connected is set as the input port. (Sm22), the function of outputting the chip select signal to the SRAM 50 is forcibly disabled. Thereafter, the voltage decreases, and the CPU 41a of the main control unit 41 stops and shifts to a standby state. And if a voltage falls in this standby state, it will be in an operation stop state internally. Therefore, the main control unit 41 reliably stops operation when power is interrupted.

  Here, a specific example of storing backup data of each program module in the game control board 40 in the SRAM 50 (backup RAM) will be described with reference to FIG.

  As described with reference to FIG. 14, among the four program modules of the internal lottery control module, the input / output control module, the reel rotation control module, and the payout control module, first, the backup data of the internal lottery control module is stored in the SRAM 50 (backup RAM). Store (Sm3). In the SRAM 50 (backup RAM), the start address designated when storing the backup data of the internal lottery control module is set to “A6000”. Therefore, the main control unit 41 designates “A6000” as the start address in the step of Sm3, and starts storing backup data of the internal lottery module generated by data conversion in the step of Sm2. Then, until all the data for the internal lottery control module stored in the work RAM are backed up, the processes of Sm1 to Sm3 are repeatedly executed while incrementing the storage destination address of the SRAM 50 (backup RAM).

  Next, after storing the backup data of the internal lottery control module, the backup data of the input / output control module is stored in the SRAM 50 (backup RAM) (Sm8). In the backup RAM, the start address designated when storing the backup data of the input / output control module is set to “A7000”. Therefore, the main control unit 41 designates “A7000” as the start address in the step Sm8, and starts storing the backup data of the input / output control module generated by data conversion in the step Sm7. The processes of Sm6 to Sm8 are repeatedly executed while incrementing the storage destination address of the SRAM 50 (backup RAM) until backup of all data for the input / output control module stored in the work RAM is completed.

  Next, after storing the backup data of the input / output control module, the backup data of the reel rotation control module is stored in the SRAM 50 (backup RAM) (Sm13). In the backup RAM, the start address designated when storing the backup data of the reel rotation control module is set to “A8000”. Therefore, the main control unit 41 designates “A8000” as the start address in step Sm13, and starts storing the backup data of the reel rotation control module generated by data conversion in step Sm12. Then, until all the data for the reel rotation control module stored in the work RAM is backed up, the processes of Sm11 to Sm13 are repeatedly executed while incrementing the storage destination address of the SRAM 50 (backup RAM).

  Next, after storing the backup data of the input / output control module, the backup data of the payout control module is stored in the SRAM 50 (backup RAM) (Sm18). In the backup RAM, the start address designated when storing the backup data of the payout control module is set to “A9000”. Therefore, in step Sm18, the main control unit 41 designates “A9000” as the start address, and starts storing backup data of the payout control module generated by data conversion in step Sm17. The processes of Sm16 to Sm18 are repeatedly executed while incrementing the storage destination address of the SRAM 50 (backup RAM) until backup of all data for the payout control module stored in the work RAM is completed.

  Thus, since backup data is stored for each program module, when only one of the program modules needs to be changed in another model, only that program module needs to be replaced, and the game control program can be easily changed. . Since the start address for storing the backup data of each program module is set for each program module, it is not necessary to maintain consistency for storing the backup data even if the model is changed. The backup data may be stored at the start address set in. For this reason, it is possible to simplify the program at the time of storing the backup data, and it is possible to reduce the man-hour for developing the program. Similarly, checksum data is also created for each program module, so even if the model is changed, there is no need to maintain consistency for storing checksum data, and the program for storing checksum data is simplified. Can reduce the man-hours for program development.

  In the slot machine 1 of this embodiment, the main control unit 41 controls the progress of the game. A MAXBET switch 6, a start switch 7, and stop switches 8L, 8C, and 8R are provided as operation switches. Of these operation switches, the start switch 7 is also used for setting value setting in a setting change state.

  The main control unit 41 detects these operation switches in a switch input determination process executed during a timer interrupt process (main) executed by interrupting at regular time intervals.

  The main control unit 41 executes a start-up process when power is turned on, and an interrupt is permitted at the end of the start-up process. Thereafter, a timer interrupt process (main) is executed at regular intervals. When the main control unit 41 can return to the state before the power interruption, a return command is transmitted to the sub-control unit 91 before interruption is permitted in the startup process. Further, if the main control unit 41 cannot return to the state before the power interruption due to an abnormality in the data stored in the RAM 41c, an error command indicating a RAM abnormality is issued before the interruption is permitted in the startup process. Sent to. If the setting key switch 37 is on and the RAM 41c is initialized and does not return to the state before the power interruption, it indicates that the setting is being changed before the interruption is permitted in the startup process. A setting change command is transmitted to the sub-control unit 91. Of the commands sent in the start-up process, the return command specifies that the main control unit 41 returns to the state before the power interruption, an error command indicating a RAM abnormality, and a setting change indicating that the setting is being changed. From the middle command, it is specified that the main control unit 41 does not return to the state before the power interruption.

  Next, the control of the effect performed by the sub-control unit 91 based on the command transmitted from the main control unit 41 to the effect control board 90 will be described.

  When the sub control unit 91 receives a command from the main control unit 41, the sub control unit 91 executes a command reception interrupt process. In the command reception interrupt process, the command acquired from the command transmission line is stored in the reception buffer provided in the RAM 91c.

  The reception buffer is provided with an area capable of storing a maximum of 16 commands so that a plurality of commands can be accumulated.

  In the timer interrupt process (sub), the sub-control unit 91 determines whether or not an unprocessed command is stored in the reception buffer. If an unprocessed command is stored, the sub-control unit 91 is the earliest. The control pattern table stored in the ROM 91b is referred to based on the command received in the stage, and the liquid crystal display 51, effect effect LED 52, speakers 53, 54, reel LED 55, etc. are controlled based on the control contents registered in the control pattern table. Performs output control of various rendering devices.

  In the control pattern table, the display pattern of the liquid crystal display 51 corresponding to the type of command, the lighting mode of the lighting effect LED 52, the output mode of the speakers 53 and 54, the lighting mode of the reel LED, etc. Control patterns of these effect devices are registered, and when the sub-control unit 91 receives a command, the sub-control unit 91 stores the control patterns registered corresponding to the effect patterns set in the RAM 91c in the game of the control pattern table. Among these, the control pattern corresponding to the type of the received command is referred to, and the output control of the rendering device is performed based on the control pattern. Thereby, the production according to the production pattern and the progress of the game is executed.

  If the sub-control unit 91 receives a new command during execution of an effect triggered by the reception of a certain command, the sub-control unit 91 stops the effect based on the control pattern being executed, and changes to the newly received command. An effect based on the corresponding control pattern is executed. In other words, even if the production is not finished to the end, when a new command is received, the production that was being executed is canceled and a new command is received unless the received new command is not a command that triggers a new production. An effect based on the command is executed.

  When the internal winning command is received, the effect pattern is selected at a selection rate corresponding to the result of the internal lottery indicated by the internal winning command, and is set in the RAM 91c. The selection rate of the effect pattern is registered in the effect table stored in the ROM 91b, and when the sub control unit 91 receives the internal winning command, the sub control unit 91 stores the effect pattern in the effect table according to the result of the internal lottery indicated by the internal winning command. With reference to the registered selection rate, one of the effect patterns is selected from a plurality of types of effect patterns according to the selection rate, and the selected effect pattern is set in the RAM 91c as the effect pattern of the game. Even if the same command is received, a different control pattern is selected depending on the effect pattern selected when the internal winning command is received. As a result, different effects may be performed depending on the effect pattern.

  In the slot machine 1 of the present embodiment, when a predetermined symbol combination is aligned on the winning line LN, a winning is achieved. The types of winning combinations are determined according to the state of the game, but can be broadly divided into special roles with transition to big bonus and regular bonus, small roles with payout of medals, and setting of bet number. There is a re-player who can start the next game without needing.

  The big bonus may be indicated as BB and the regular bonus may be indicated as RB. In some cases, a big bonus or a regular bonus is simply referred to as a bonus. In order for winning of each combination determined according to the gaming state to occur, it is necessary to set a winning flag in the RAM 41c to win the internal lottery and allow winning of the winning combination.

  FIG. 16 to FIG. 18 are diagrams for explaining the types of winning combinations, symbol combinations of winning combinations, and technical matters related to winning combinations. FIG. 19 is a diagram for explaining the gaming state controlled by the main control unit 41 and the transition of RT.

  As shown in FIG. 19, the slot machine according to the present embodiment is controlled as a normal gaming state, one in the inside, two in the inside, RB, or BB (RB) as the gaming state. In addition, RT is a replay time in which the probability of a replay is increased. In a normal gaming state (hereinafter, the normal gaming state is referred to as normal), any type of RT (replay) from RT0 to RT4 is used. Time).

  Among the winning combinations, the special combination includes 6 types of bonuses such as big bonuses 1 to 4 and regular bonuses 1 and 2.

  BB1 is awarded when the combination of “Black 7-Black 7-Black 7” is aligned on the winning line LN. BB2 is awarded when the combination of “network 7-network 7-network 7” is aligned on the winning line LN. BB3 is awarded when the combination of “white 7-white 7-white 7” is aligned on the winning line LN. BB4 is awarded when the combination of “BAR-BAR-BAR” is aligned on the winning line LN. BB4 is awarded when the combination of “black 7-white 7-net 7” is aligned on the winning line LN.

  When winning one of BB1 to BB4, the game shifts to a big bonus that is controlled by the game every time during the BB regular bonus (hereinafter referred to as BBRB).

  The big bonus generated due to the winning of any one of BB1 to BB4 is terminated on condition that 316 or more medals have been paid out.

  RB1 wins when the winning line LN has a combination of “net 7-net 7-black 7”. RB2 is awarded when the combination of “white 7-white 7-black 7” is aligned on the winning line LN.

  When winning one of RB1 and RB2, a transition is made to a regular bonus (hereinafter referred to as RB).

  The regular bonus generated due to the winning of either RB1 or RB2 ends on the condition that any winning combination has won 6 times or 12 games have been consumed.

  As shown in FIG. 19, from the internal winning one of BB1, BB3, RB2 to winning a prize, it is controlled to 1 inside / RT0, and after winning an internal winning one of BB2, BB4, RB1 Until this is done, the internal control is controlled to 2 · RT0. Further, as shown in FIG. 18, after the big bonus or regular bonus (collectively referred to as a bonus) is completed, the control is performed to normal RT4.

  Even if one of BB1 to BB4, RB1, or RB2 is won in an internal lottery to be described later, if the stop switches 8L, 8C, and 8R are not operated at an appropriate timing to enable winning of these roles, these I won't win a role. The symbols composing BB1 to BB4, RB1, and RB2 ("black 7", "white 7", and "net 7") are arranged within 5 frames on each of the left reel 2L, middle reel 2C, and right reel 2R. This is because it has not been done.

  Next, with reference to FIG. 16, the small combination among the winning combinations will be described. Among the winning roles, there are middle bells, lower right bells, upper bells 1-8, middle watermelons, right lower watermelons, upper watermelons, lower cherries, middle cherries, one role, right-up bells, right-up bevels, Includes a rising rivet.

  For example, the middle bell is awarded when the combination of “bell-bell-bell” is arranged on the winning line LN, and eight medals are paid out.

  Here, referring to FIG. 3, the bells are arranged within 5 frames in each of the left reel 2L, the middle reel 2C, and the right reel 2R. For this reason, it can be said that, in principle, when a middle bell is won in an internal lottery to be described later, it can be said that a winning can be made regardless of the operation timing of the stop switches 8L to 8R.

  Below, right-down bell, upper bell 1-8, middle watermelon, right-down watermelon, upper watermelon, lower cherry, middle cherry, single role, right-up bell, right-up bevel, right-up rebebe are also shown in FIG. When the combinations of the symbols shown are complete, a prize is awarded and the payout number of medals shown in FIG. 16 is paid out. As shown in FIG. 3, the right-down bell, the right-up bell, the right-up bevel, and the right-up bevel are arranged within 5 frames, so that a prize is won regardless of the operation timing of the stop switches 8L to 8R. Can be made, but the upper bell 1-8, middle watermelon, right-down watermelon, upper watermelon, lower cherry, middle cherry, 1 piece role, because there are places where the configuration symbol is not arranged within 5 frames, If a stop switch corresponding to a reel whose symbol is not arranged within 5 frames is not operated at an appropriate timing, no prize is won.

  Next, with reference to FIG. 17, the re-game player among the winning combinations will be described. Among the winning combinations, the replaying role includes normal replay, lower stage replay, fall replay, promotion replays 1 and 2, special replay, and SP (special) replay.

  For example, the normal replay is performed when a combination of “Replay-Replay-Replay”, “Replay-Replay-Plum”, “Plum-Replay-Replay”, and “Plum-Replay-Plum” is arranged on the winning line LN. Become. Replays and plums are arranged within 5 frames in each of the left reel 2L, middle reel 2C, and right reel 2R. Therefore, as a general rule, it can be said that the normal replay is a role that can be won regardless of the operation timing of the stop switches 8L to 8R if the winning is made.

  Hereinafter, the lower replay, the fall replay, the promoted replays 1 and 2, the special replay, and the SP (special) replay are similarly awarded when the combinations of symbols shown in FIG. Also, as shown in FIG. 3, each of these replays is arranged within 5 frames, so that if it is elected, it can be awarded regardless of the operation timing of the stop switches 8L to 8R. It can be said.

  As shown in FIG. 19, after winning the fall replay in normal / RT0, it is controlled to RT1.

  In addition, after winning a promotion replay (promotion replay 1 or promotion replay 2) in normal / RT1, it is controlled to normal / RT0. As will be described later, the promotion replay is set not to win independently in the internal lottery in normal / RT2, normal / RT3, and normal / RT4. Further, when the special combination and the promotion replay are won at the same time in the internal lottery in the normal / RT2, the normal / RT3, and the normal / RT4, it is controlled to the internal 1 / RT0 or the internal 2 / RT0 at that time. For this reason, no promotion replay is won in normal / RT2, normal / RT3, or normal / RT4. As a result, it is configured not to be controlled from normal / RT2, normal / RT3, normal / RT4 to normal / RT0, and only when it is normal / RT1 is promoted replay, and only from normal / RT1 is normal / RT0. It is comprised so that it may be controlled.

  In addition, after winning the special replay in normal / RT1 and normal / RT3, it is controlled to normal / RT2. As will be described later, the special replay is set so as not to be won independently in the internal lottery in the normal / RT1 and normal / RT4. Further, when the special combination and special replay are won at the same time in the internal / RT1 or normal / RT4 internal lottery, the internal 1 / RT0 or the internal 2 / RT0 is controlled at that time. Therefore, the special replay is not won in normal / RT1 and normal / RT4. As a result, it is configured not to be controlled from normal / RT1, normal / RT4 to normal / RT2, and a special replay is awarded only in normal / RT0, normal / RT3, and from normal / RT0 / normal / RT3. Only normal and RT2 are controlled. When the special replay is won in the normal RT2, the normal RT2 is maintained.

  As shown in FIG. 19, after winning the SP replay in normal / RT2, the control is performed in normal / RT3. As will be described later, the SP replay is set not to win independently in the internal lottery in the normal / RT0, normal / RT1, and normal / RT4. Further, when the special combination and SP replay are won at the same time in the internal lottery in the normal / RT0, normal / RT1, and normal / RT4, the internal one / RT0 or the internal two / RT0 is controlled at that time. Therefore, the SP replay is not won in the normal / RT0, normal / RT1, and normal / RT4. As a result, normal / RT0, normal / RT1, and normal / RT4 are not controlled to normal / RT3, and SP replay is awarded only when normal / RT2 and normal / RT3 only from normal / RT2. It is comprised so that it may be controlled. If the special replay is won in the normal RT3, the normal RT3 is maintained.

  Next, the transition outcome will be described with reference to FIG. As shown in FIG. 18, the transition items are composed of 20 types of combinations such as “Replay-Orange-Bell”. In this embodiment, left bells 1 to 4, middle bells 1 to 4 and right bells 1 to 4 which will be described later are elected, and the upper bells which are elected as the first stop other than the reels which become the winning conditions for the middle bells are elected. When the game is missed, the above-mentioned transition outcome is aligned with the winning line LN.

  As shown in FIG. 19, normal / RT1 is controlled after the transition points are aligned with the winning line LN in normal / RT0, normal / RT2, normal / RT3, and normal / RT4. Note that, when the transition outcomes are aligned with the winning line LN in the normal / RT1, the normal / RT1 is maintained.

  Next, a combination of lottery target combinations that are read out as lottery target combinations for each gaming state will be described. In this embodiment, the gaming state is the normal gaming state, the inside one (BB1, BB3, RB2 is elected) or the inside 2 (BB2, BB4, RB1 is won) State), BB (RB), or RB, and the winning combination and the winning probability for the internal lottery are different. Furthermore, if the gaming state is the normal gaming state, at least one of the re-game player and the winning probability to be subject to the internal lottery differs depending on the types of RT0 to RT4. As will be described later as a lottery target combination, a plurality of winning combinations can be read out simultaneously and can be won in duplicate. In the following, “+” is indicated between winning combinations to indicate that the winning combination is simultaneously read out in the internal lottery.

  When normal / RT0, BB1, BB1 + weak watermelon, BB1 + strong watermelon, BB1 + weak cherry, BB1 + strong cherry, BB1 + middle tier, BB1 + 1 double-player, BB1 + normal replay, BB1 + fall replay, BB1 + promoted replay, BB1 + special replay, BB1 + SP Replay, BB2, BB2 + weak watermelon, BB2 + strong watermelon, BB2 + weak cherry, BB2 + strong cherry, BB2 + middle cherries, BB2 + one piece, BB2 + normal replay, BB2 + tumble replay, BB2 + promoted replay, BB2 + special replay, BB3, BB3 + weak watermelon, BB3 + strong watermelon, BB3 + weak cherry, BB3 + strong cherry, BB3 + middle cherries, BB3 + 1 sheet, BB3 + normal replay, BB3 + tumble replay, BB3 + promoted replay, BB3 + Especially replay, BB4, BB4 + middle cherries, BB4 + 1 sheets, BB4 + special replay, RB1, RB1 + strong watermelon, RB1 + weak cherries, RB1 + strong cherry, RB1 + 1 sheets, RB2, RB2 + weak watermelon, RB2 + strong watermelon, RB2 + weak cherry, RB2 + Strong cherry, RB2 + 1 role, bell, left bell 1, left bell 2, left bell 3, left bell 4, middle bell 1, middle bell 2, middle bell 3, middle bell 4, right bell 1, right bell 2, right Bell 3, right bell 4, weak watermelon, strong watermelon, weak cherry, strong cherry, middle tier cherry, 1 part, replay GR11, replay GR12, replay GR13, replay GR14, replay GR15, replay GR16, replay GR21, replay GR22, Replay GR23, Replay GR24, and Replay GR25 are internal lottery pairs The role.

  In addition, a weak watermelon is an upper stage watermelon + right-down watermelon. That is, when the upper watermelon wins, it can be recognized that it is a weak watermelon. A strong watermelon is a middle-stage watermelon + right-down watermelon. That is, when the middle stage watermelon wins, it can be recognized that it is a strong watermelon.

  A weak cherry is a lower cherry alone, and a strong cherry is a lower cherry plus one piece. In the weak cherry, the reel is controlled so that the cherry stops at the lower stage of the left reel 2L and the combination of “BAR-orange-any” or “BAR-bell-any” can be stopped at the middle stage. On the other hand, in the case of strong cherry, cherry stops at the lower stage of the left reel 2L, and not only “BAR-orange-any” or “BAR-bell-any” but also the combination of “BAR-BAR-any” stops at the middle stage. Possible reel control is performed. That is, the combination of “BAR-BAR-any” can be stopped only in the middle cherries. Thereby, it can be recognized that a strong cherry was won by having “BAR-BAR-any” in the middle.

  The promotion replay is promotion replay 1 + promotion replay 2. The bell is a middle bell + a downward-sloping bell. Left bell 1 is right falling bell 5 + upper bell 5 + upper bell 8, left bell 2 is right falling bell + upper bell 6 + upper bell 7, and left bell 3 is right falling bell + upper bell 2 + upper bell 3, left bell 4 is right falling bell + upper bell 2 + upper bell 4. The left bells 1 to 4 are also simply called left bells. The middle bell 1 is the middle bell + the upper bell 2 + the upper bell 5, the middle bell 2 is the middle bell + the upper bell 1 + the upper bell 6, and the middle bell 3 is the middle bell + the upper bell 4 + the upper bell. 7 and the middle bell 4 is the middle bell + the upper bell 3 + the upper bell 8. The middle bells 1 to 4 are also simply called middle bells. The right bell 1 is the middle bell + the upper bell 3 + the upper bell 5, the right bell 2 is the middle bell + the upper bell 1 + the upper bell 7, and the right bell 3 is the middle bell + the upper bell 4 + the upper bell. 6 and the right bell 4 is the middle bell + the upper bell 2 + the upper bell 8. The right bells 1 to 4 are also simply called right bells. The left bells 1 to 4, the middle bells 1 to 4, and the right bells 1 to 4 are also simply referred to as push order bells.

  Replay GR11 is a fall replay + promotion replay 2, replay GR12 is a fall replay + promotion replay 2 + normal replay, replay GR13 is a fall replay + promotion replay 1, and replay GR14 is a fall Replay + promotion replay 1 + normal replay, replay GR15 is fall replay + promotion replay 1 + promotion replay 2, and replay GR16 is fall replay + promotion replay 1 + promotion replay 2 + normal replay.

  Replay GR21 is tumble replay + special replay, replay GR22 is tumble replay + special replay + normal replay, replay GR23 is tumble replay + special replay + lower replay, and replay GR24 is Tumble replay + special replay + normal replay + lower replay. Replay GR25 is tumble replay + special replay + promotion replay 1.

  When normal / RT4, BB1, BB1 + weak watermelon, BB1 + strong watermelon, BB1 + weak cherry, BB1 + strong cherry, BB1 + middle cherries, BB1 + 1 roll, BB1 + normal replay, BB1 + fall replay, BB1 + promoted replay, BB1 + special replay, BB1 + SP Replay, BB2, BB2 + weak watermelon, BB2 + strong watermelon, BB2 + weak cherry, BB2 + strong cherry, BB2 + middle cherries, BB2 + one piece, BB2 + normal replay, BB2 + tumble replay, BB2 + promoted replay, BB2 + special replay, BB3, BB3 + weak watermelon, BB3 + strong watermelon, BB3 + weak cherry, BB3 + strong cherry, BB3 + middle cherries, BB3 + 1 sheet, BB3 + normal replay, BB3 + tumble replay, BB3 + promoted replay, BB3 + Especially replay, BB4, BB4 + middle cherries, BB4 + 1 sheets, BB4 + special replay, RB1, RB1 + strong watermelon, RB1 + weak cherries, RB1 + strong cherry, RB1 + 1 sheets, RB2, RB2 + weak watermelon, RB2 + strong watermelon, RB2 + weak cherry, RB2 + Strong cherry, RB2 + 1 role, bell, left bell 1, left bell 2, left bell 3, left bell 4, middle bell 1, middle bell 2, middle bell 3, middle bell 4, right bell 1, right bell 2, right Bell 3, right bell 4, weak watermelon, strong watermelon, weak cherry, strong cherry, middle cherries, one-piece combination, and normal replay are targeted for internal lottery.

  Also, in RT0-4, etc., the winning probability of weak cherries, middle cherries, and strong cherries, which are small roles that trigger the later-described AT lottery conditions, is highest for weak cherries, and then highest for middle cherries. The strong cherry is set to be the lowest. On the other hand, when these weak cherries, middle cherries, and strong cherries are won, the ratio of winning BB and RB is highest for strong cherries, followed by middle cherries and lowest cherries. Is set. Similarly, when a weak cherry, middle tier cherry, or strong cherry is won, the probability of winning an AT and the number of AT games determined is higher for the strong cherries than for the middle cherries and weak cherries. It is set to be. This point will be described later with reference to FIGS.

  When internal center 1 · RT0, internal center 2 · RT0, bell, left bell 1, left bell 2, left bell 3, left bell 4, center bell 1, center bell 2, center bell 3, center bell 4, right Bell 1, Right bell 2, Right bell 3, Right bell 4, Weak watermelon, Strong watermelon, Weak cherry, Strong cherry, Middle cherry, Single role, Normal replay, Lower replay, SP replay, Tumble replay, Promotion replay, Special Replay is the target for internal lottery.

  When it is BBRB · RT0, the weak cherry and all roles are subject to internal lottery, and when it is RB · RT0, all roles, RB bell 1, RB bell 2, and RB bell 3 are subject to internal lottery.

  All roles are all small roles other than right-up bevel, ie middle bell + right-down bell + upper bell 1 + upper bell 2 + upper bell 3 + upper bell 4 + upper bell 5 + upper bell 6 + upper bell 7 + upper bell 8 + middle watermelon + Lower right watermelon + upper watermelon + lower cherry + middle cherries + 1 piece + right rising bell + right rising rivet.

  The RB bell 1 is a right-up bell + right-up bevel, the RB bell 2 is a right-up bell + right-up bevel + right-up beryl, and the RB bell 3 is all small roles, that is, the middle stage bell. + Downward bell + Upper bell 1 + Upper bell 2 + Upper bell 3 + Upper bell 4 + Upper bell 5 + Upper bell 6 + Upper bell 7 + Upper bell 8 + Middle watermelon + Lower watermelon + Upper watermelon + Lower cherry + Middle cherry + Single role + Upright Bell + bevel up to the right + bevel up to the right.

  Also, in normal / RT0-4, etc., weak watermelon, strong watermelon, weak cherry, strong cherry, middle cherries, single role, normal replay, fall replay, promotion that can be elected simultaneously with any of BB1-BB4, RB1, RB2 The replay and SP replay judgment values are read separately from the bonus in internal 1 · RT0 and internal 2 · RT0, respectively, strong watermelon, weak cherry, strong cherry, middle cherries, one-piece role, normal Since it is added to Replay, Tumble Replay, Promotion Replay, and SP Replay, the winning probability of each of Strong Watermelon, Weak Cherry, Strong Cherry, Middle Cherry, Single Role, Normal Replay, Tumble Replay, Promotion Replay, and SP Replay is constant. It is secured to be.

  In this way, the internal lottery role varies depending on whether the gaming state is the normal gaming state, 1 or 2 inside, BB (RB), or RB, and BB (RB) In RB, the internal lottery is performed using a lottery table in which the winning probability of the small role is set higher than that in the normal gaming state and inside.

  Also, when the game state is 1 or 2 in the inside, the subject of the internal lottery does not change depending on whether it is 1 in the inside or 2 in the inside, but it is 1 in the inside or inside The internal lottery is performed using a lottery table in which the winning probabilities of the target re-gamer are different.

  In addition, when the gaming state is the normal gaming state, the re-game player to be subject to the internal lottery differs depending on whether it is RT0-4, and depending on whether it is RT0-4 An internal lottery is performed using a lottery table with different re-game players and their winning probabilities.

  As will be described in detail later, in this embodiment, when a plurality of types of small roles (bells) and a plurality of types of replaying players are simultaneously elected, the type of the selected small role or replaying role and a stop switch Control is performed so that the symbol combination of the small combination and the combination of the re-playing combination determined according to the pressing order of 8L, 8C, and 8R are aligned and stopped on the winning line LN within the drawing range of up to four frames. Accordingly, the types of the small combination and re-playing combination to be won simultaneously will be specifically described with reference to FIGS. 20 to 22. FIG. 20 shows a list of small combinations and re-playing combination to be simultaneously won. FIG. 21 shows reel control when a plurality of replays are won simultaneously, and FIG. 22 shows reel control when a plurality of small roles are won simultaneously.

  As shown in FIG. 20 and FIG. 21, for example, when the replay GR1 (normal replay + promotion replay 1) is won and the stop operation is performed in the order of left middle right (procedure), Among them, the control for stopping the combination of the promotion replay 1 on the winning line LN is performed, and when the stop operation is performed in the order other than the left middle right, the control for stopping the combination of the normal replay on the winning line LN is performed. Do.

  Similarly, when the replays GR2 to 6 are stopped in a predetermined order, the combination of the promoted replay 1 or the promoted replay 2 among the selected re-playing players is stopped in alignment with the winning line LN. If the stop operation is performed in an order other than the predetermined order, control is performed so that the combination of the normal replays is aligned with the winning line LN and stopped.

  As shown in FIG. 3, the symbols constituting the promotion replay 1, the promotion replay 2, and the normal replay are arranged at intervals of 5 frames or less on all of the left reel 2L, the middle reel 2C, and the right reel 2R. The reel control is performed so that the promotion replay 1, the promotion replay 2 or the normal replay always wins regardless of the stop operation timing of the stop switches 8L to 8R according to the operation order.

  Therefore, in the normal / RT1 where the replays GR1 to 6 are the targets of the internal lottery, if any of the replays GR1 to GR6 is elected, the promoted replay wins with a probability of 1/6, and the normal / RT0 Will be migrated.

  Similarly, when the replays GR11 to 16 are stopped in a predetermined order, the combination of the promoted replay 1 or the promoted replay 2 among the selected re-playing players is aligned with the winning line LN and stopped. If the stop operation is performed in an order other than the predetermined order, control is performed so that the combination of falling replays is aligned with the winning line LN and stopped.

  As shown in FIG. 3, the symbols constituting the promotion replay 1, the promotion replay 2, and the fall replay are arranged at intervals of 5 frames or less on all of the left reel 2L, the middle reel 2C, and the right reel 2R. The reel control is performed so that the promotion replay 1, the promotion replay 2 or the fall replay always wins regardless of the stop operation timing of the stop switches 8L to 8R according to the operation order.

  Therefore, in the normal / RT0 where the replay GRs 11-16 are subject to internal lottery, if any of the replays GR11-16 is elected, the promoted replay wins with a probability of 1/6 and the normal / RT0 is maintained. On the other hand, the fall replay wins with a probability of 5/6 and shifts to normal RT1.

  In addition, in the replays GR21 to GR25, when a stop operation is performed in a predetermined order, the special replay combination among the selected replay players is controlled so as to be aligned with the winning line LN and stopped. When stop operations are performed in order, control is performed so that the combination of falling replays is aligned with the winning line LN and stopped.

  As shown in FIG. 3, since the symbols constituting the special replay and the fall replay are arranged at intervals of 5 frames or less in all of the left reel 2L, the middle reel 2C, and the right reel 2R, Regardless of the stop operation timing of the stop switches 8L to 8R, the reel control is performed so that the special replay or the fall replay is always won.

  For this reason, if one of the replays GR21 to 25 is elected in the normal / RT0 in which the replays GR21 to 25 are the targets of the internal lottery, the special replay wins with a probability of 1/5 and shifts to the normal / RT2. On the other hand, the fall replay wins with a probability of 4/5 and shifts to normal RT1.

  Further, in the replay GR31 to 36, when the stop operation is performed in a predetermined order (left push), the control for stopping the combination of the SP replay or the normal replay among the selected replay players in the winning line LN is stopped. If the stop operation is performed in an order other than the predetermined order, the special replay combination is controlled to be aligned with the winning line LN and stopped.

  As shown in FIG. 3, the symbols constituting the SP replay, special replay, and normal replay are arranged at intervals of 5 frames or less on all of the left reel 2L, the middle reel 2C, and the right reel 2R. Accordingly, the reel control is performed so that the SP replay, special replay, or normal replay always wins regardless of the stop operation timing of the stop switches 8L to 8R.

  In addition, in normal / RT3 where the replay GRs 31 to 36 are the targets of the internal lottery, if one of the replays GR31 to 36 is won, the SP replay wins with a probability of 1/6 and one navigation stock described later On the other hand, the normal replay wins with a probability of 1/6 and normal RT3 is maintained, and the special replay wins with a probability of 4/6 and shifts to normal RT2.

  As shown in FIG. 20 and FIG. 22, when the left bells 1 to 5 are elected, and the stop operation is performed by pressing the left button, the combination of the right falling bells among the selected small roles is aligned with the winning line LN and stopped. When the stop operation is performed by middle press or right press, the control is performed so that any combination of the upper bells 2 to 8 or the shift outcome is aligned with the pay line LN.

  As shown in FIG. 3, the configuration symbol of the right-down bell is arranged at intervals of 5 frames or less on all reels, and when the left bells 1 to 4 are elected, a stop operation is performed by pushing left. In this case, regardless of the timing of the stop operation, control is always performed so that the right lowering bell is aligned with the winning line LN, while the symbols constituting the upper bells 1 to 8 are at intervals of 5 frames or more on all reels. Even if the left bells 1 to 4 are elected because there are places that are arranged, if the stop operation is performed by pressing the middle or right, it becomes the drawing range of the constituent symbols of the elected upper bells 1 to 8 If the stop operation is not performed at an appropriate timing, the winning upper bell cannot be aligned with the winning line LN, and in this case, the control is performed so that the transition outcome is aligned with the winning line LN.

  In addition, when the middle bells 1 to 4 are elected and the stop operation is performed by pressing the middle bell, the combination of the middle bells among the selected small roles is controlled to be aligned with the winning line LN and stopped, and left or right pressed. When the stop operation is performed at, control is performed so that any combination of the upper bells 1 to 8 or the transition outcome is aligned with the winning line LN and stopped.

  As shown in FIG. 3, the configuration symbols of the middle bell are arranged at intervals of 5 frames or less on all reels, and when the middle bell 1 to 4 is elected, when the stop operation is performed by middle push Regardless of the timing of the stop operation, control is always performed so that the middle bell is aligned with the winning line LN, while the symbols constituting the upper bells 1 to 8 are arranged at intervals of 5 frames or more on all reels. Even if the middle bells 1 to 4 are elected, if the stop operation is performed by pressing left or right, an appropriate range that will be drawn in the constituent symbols of the elected upper bells 1 to 8 will be used. If the stop operation is not performed at the timing, the selected upper bell cannot be aligned with the winning line LN, and in this case, control is performed so that the shift outcome is aligned with the winning line LN.

  If right bells 1 to 4 are elected and stop operation is performed by pressing right, control is performed to stop the combination of middle bells in the selected small role in line with winning line LN, and stop by pressing left or middle. When an operation is performed, control is performed to stop any combination of the upper bells 1 to 8 or the transition outcome in line with the pay line LN.

  As shown in FIG. 3, the configuration symbols of the middle bell are arranged at intervals of 5 frames or less on all reels, and when the right bell 1 to 4 is elected, when the stop operation is performed by pushing right However, regardless of the timing of the stop operation, control is always performed so that the middle bell is aligned with the winning line LN, while the symbols constituting the upper bells 1 to 8 are arranged at intervals of 5 frames or more on all reels. Therefore, even if the right bells 1 to 4 are elected, if the stop operation is performed by left-pressing or middle-pressing, an appropriate drawing range of the constituent symbols of the elected upper bells 1 to 8 is appropriate. If the stop operation is not performed at the timing, the selected upper bell cannot be aligned with the winning line LN, and in this case, control is performed so that the shift outcome is aligned with the winning line LN.

  Thus, in this embodiment, when any of the left bell, middle bell, right bell, that is, the push order bell is won, by performing a stop operation in a specific operation mode according to the type of winning combination, While the right-down bell or middle bell always wins, if the stop operation is performed in an operation mode other than the specific operation mode according to the type of winning combination, the upper bell is aligned at 1/4, but at 3/4 In some cases, the upper bells are not aligned and the transition outcomes are aligned.

  For this reason, at the time of winning the push order bell, the expected value of the number of medals to be paid out can be changed depending on whether or not it is operated in a specific operation mode (procedure) according to the type of winning combination. In other words, even if one of the push order bells is won, it is impossible to intentionally select a specific operation mode unless the type is known. Although a medal can be surely obtained by winning a prize, the upper bell can be won only by 1/4 at a ratio of 2/3, and a medal cannot be surely obtained.

  When RB bell 1 (Right-up bell + Right-up Rivebe) is elected and a stop operation is performed by left-pressing, control is performed so that the combination of right-up bells among the selected small roles is aligned with the winning line LN and stopped. If a stop operation is performed by middle pressing or right pressing, control is performed to align the combination of rising right ribs on the winning line LN and stop.

  If RB Bell 2 (Rising Right Bell + Right Rising Bevel + Right Rising Berri) is won and stopped by pressing the middle, the combination of the right rising bells of the selected small roles is aligned with the winning line LN and stopped. If the stop operation is performed by pressing the button to the left, the control is performed to stop the right-up bevel combination in alignment with the winning line LN. If the stop operation is performed by pressing the button to the right, Control is performed to stop the combination in line with the winning line LN.

  RB bell 3 (middle bell + lower right bell + upper bell 1 + upper bell 3 + upper bell 4 + upper bell 5 + upper bell 6 + upper bell 7 + upper bell 8 + middle watermelon + lower watermelon + upper watermelon + lower cherry + middle cherry +1 sheet role + right-up bell + right-up bevel + right-up bevel), and if the stop operation is performed by pressing right, the combination of right-up bells in the selected small role is aligned with the winning line LN Control to stop is performed, and when a stop operation is performed by left-pressing or middle-pressing, control is performed to stop the right-beveled bevel combination aligned with the winning line LN.

  As shown in FIG. 3, the configuration symbols of the right-up bell, the right-up bevel, and the right-up bevel are arranged at intervals of 5 frames or less on all reels, and when the RB bells 1 to 4 are won, Regardless of the timing of the stop operation, any combination of right-up bell, right-up ribebe and right-up bevel will be aligned on the winning line LN and 10 medals will be paid out, but at a rate of 1/3 Only "bell-bell-bell" combinations will be aligned to the right.

  Although not particularly shown, when a bell (middle bell + lower right bell) is won, a combination of “bell-bell-bell” is arranged on the winning line LN regardless of the stop order of the reels and the operation timing. To be controlled.

  Also, all roles (middle bell + lower right bell + upper bell 1 + upper bell 2 + upper bell 3 + upper bell 4 + upper bell 5 + upper bell 6 + upper bell 7 + upper bell 8 + middle watermelon + right lower watermelon + upper watermelon + lower cherry + middle (Cherry + 1 hand + right-up bell + right-up rivebe) is selected, the “bell-bell-bell” combination is controlled to rise to the right regardless of the reel stop order and operation timing. The

  In this embodiment, as shown in FIG. 19, it is controlled to one of the normal gaming state, internal 1, internal 2, RB, BB (RB), and in the normal gaming state, any of RT 0 to 4 Controlled.

  Normal / RT0 is normal / RT1 when a promotion replay wins (when either one of the replays GR1 to GR6 is elected and a stop operation is performed in the order in which the promotion replay wins), normal / RT1 or normal / RT2 Shifts when the game is completed due to the consumption of the specified number of games. Regardless of the number of games after the transition to normal / RT0, the normal / RT0 shifts to the normal / RT1 by winning the fall replay or stopping the transition, or to the normal / RT2 by winning the special replay It ends when the special role is elected and moves to the inside 1 or inside 2 inside.

  Normal / RT1 shifts when the transition is stopped at normal / RT0, normal / RT2, normal / RT3, normal / RT4, or when a fall replay wins at normal / RT0. The normal RT1 is such that the number of remaining RT games is subtracted for each game, and the normal number of RT remaining games is reduced to 0 by digesting the specified number of games (1000G in this embodiment).・ It will end when it shifts to RT0, or when the special role is elected and shifts to 1 inside or 2 inside.

  Normal / RT2 shifts when a special replay wins in normal / RT0 or normal / RT3. The normal RT 2 is such that the number of remaining RT games is subtracted for each game, and the normal number of RT remaining games is reduced to 0 by digesting the specified number of games (30G in this embodiment).・ Move to RT0, SP replay wins and move to normal ・ RT3, or move to stop and move to normal ・ RT1, or special role wins and becomes 1 in internal or 2 in internal It ends by migrating.

  Normal / RT3 shifts when SP replay wins in normal / RT2. Regardless of the number of games since the transition to normal / RT3, whether or not the normal / RT3 shifts to the normal / RT2 with the special replay winning, or the transition outcome stops and shifts to the normal / RT1 When the special role is elected and moves to the inside 1 or the inside 2, it ends.

  Normal / RT4 shifts to the end of BB (RB) and RB. Regardless of the number of games since the transition to the normal / RT4, the normal / RT4 stops the transition and moves to the RT1, or the special role is elected and moves to the internal 1 or the internal 2 To finish.

  The inside 1 shifts when BB1, BB3, RB2 among the special roles are won in the normal gaming state. Then, regardless of the number of games since the transition to the inside, the inside 1 finishes when the special role that triggered the transition to the inside 1 wins and shifts to BB (RB) or RB. .

  The inside 2 shifts when BB2, BB4, RB1 among special roles are won in the normal gaming state. Then, inside 2 ends regardless of the number of games since the transition to the inside, when the special combination that triggered the transition to the inside 2 wins and shifts to BB (RB) or RB. .

  RB shifts when RB1 or RB2 wins in 1 and 2 inside. And RB is complete | finished by digesting 12 games or winning 6 times.

  BB (RB) shifts when BB wins inside. Then, BB (RB) ends when the total number of medals paid out to BB (RB) exceeds the prescribed number, regardless of the number of games since the transition to BB (RB).

  Further, in the slot machine according to the present embodiment, when the gaming state is RT0 to 3, the sub-control unit 91 provides an assist time (hereinafter referred to as AT) that is a notification period in which a navigation effect that notifies the internal lottery result can be executed. The production state can be controlled.

  Here, the gaming state and the transition state of RT will be described. As shown in FIG. 19, when RB or BB (RB) ends, the routine proceeds to normal RT4.

  In normal / RT4, when the transition is stopped, the transition is made to RT1, and when the special role is elected, the transition is made to internal 1 or internal 2 according to the type of the special role won.

  In normal / RT4, if any of the left bells 1-4, middle bells 1-4, right bells 1-4 is won and the small role cannot be won, the transitional outcome will stop. Therefore, any of the left bell 1-4, the middle bell 1-4, the right bell 1-4 can be won and the small role can be won in the normal RT 4 which has been shifted to after the end of RB or BB (RB) If not, the process moves to normal RT1.

  Normally, in RT1, the special role is not won, the promotion replay is not won, the specified number of games (1000G) is consumed, or the promotion replay wins, and the normal role is transferred to RT0, and the special role is won Depending on the type of the special role that has been won, the game moves to the inside 1 or 2 inside.

  Usually ・ Replay GR1-6 wins in RT1, and the promotion replay wins when the stop order is correct. Therefore, in normal ・ RT1, replay GR1-6 wins and corrects in the order of stop. It will shift to RT0.

  In normal / RT0, if the fall replay wins, or if the transition is stopped, it moves to normal / RT1, and if the special replay wins, it moves to normal / RT2, and the special role is won. Depending on the type of the special role, it shifts to 1 inside or 2 inside.

  Usually, the replays GR11 to 16 are won at RT0, the promotion replay wins when the stopping order is correct, and the fall replay wins when the answer is incorrect. In addition, when the replays GR21 to 25 are elected in normal / RT0 and the stop order is correct, the special replay is won, and if the answer is incorrect, the fall replay is won. In addition, in the case of normal / RT0, when any one of the left bells 1 to 4, the middle bells 1 to 4 and the right bells 1 to 4 is won and the small role cannot be won, the transitional outcome stops. Therefore, in normal / RT0, the replay GRs 21 to 25 are elected and the stop order is correct, so that the transition is made to normal / RT2 and the replay GRs 11 to 16 are elected and the stop order is incorrect or the left bell 1 -4, middle bell 1 to 4, right bell 1 to 4 are elected, and if it is not possible to win a small role, it will shift to normal · RT1.

  Normally, in RT2, the special role is not won, SP replay is not won, and the regular game number (30G) is used to move to normal RT0, and SP replay is won to move to normal RT3, When the special role is elected, it shifts to 1 inside or 2 inside depending on the kind of the special role won.

  In normal / RT2, the replay GRs 31 to 36 are won, and the SP replay wins when the stop order is correct. Further, in the normal / RT2, when any of the left bell 1 to 4, the middle bell 1 to 4 and the right bell 1 to 4 is won and the small role cannot be won, the transitional outcome stops. For this reason, in normal / RT2, the replays GR31 to 36 are elected, and when the stopping order is correct, the routine proceeds to normal / RT3, and any of the left bell 1 to 4, the middle bell 1 to 4, and the right bell 1 to 4 Will be transferred to normal / RT1 if the winning combination is not successful.

  In normal / RT3, when the special replay wins, it moves to RT2, and when the transition roll stops, it moves to normal / RT1, and the special role is elected. Transition to Medium 1 or Internal 2

  In normal / RT3, the replay GRs 31 to 36 are elected, the SP replay or the normal replay is won when the stop order is correct, and the special replay is won if the answer is incorrect. Further, in the normal / RT3, when any one of the left bells 1 to 4, the middle bells 1 to 4 and the right bells 1 to 4 is won and the small role cannot be won, the transitional outcome is stopped. For this reason, in normal / RT3, the replay GRs 31 to 36 are elected, and the stop order becomes incorrect, so the routine proceeds to normal / RT2, and the left bell 1 to 4, the middle bell 1 to 4, the right bell 1 to 4 If either of them wins and the small combination cannot be won, the routine will shift to RT1.

  In the inside 1 and 2, the special role that triggers the transition to the inside wins a transition to RB or BB (RB).

  Next, various control contents executed by the sub-control unit 91 in the present embodiment will be described below with reference to FIGS.

  When the reset signal to the sub CPU 91a is input from the reset circuit 95, the sub control unit 91 performs the startup process (sub) shown in the flowcharts of FIGS.

  First, after the built-in device, peripheral IC, interrupt mode, stack pointer, etc. are initialized (Sn1), the general-purpose port setting corresponding to the general-purpose terminal connected to the CS signal line connected to the SRAM 99 is set as the output port. By setting (Sn2-1), after enabling the output of the chip select signal of the SRAM 99, access to the RAM 91c (work RAM) is permitted (Sn2-2). Next, it is determined whether or not the return command generated in Sa24a of the activation process (main) in FIGS. 8 to 10 is received from the main control unit 41 (Sn3). If the return command has not been received, it is determined whether or not the setting changing command generated in Sa27 of the startup process (main) of FIGS. 8 to 10 has been received from the main control unit 41 (Sn4). When a setting change command is received, a setting reception command flag indicating that the setting change command has been received is stored in a predetermined area of the RAM 91c (Sn5).

  When a return command is received or a setting changing command is received, it is determined whether or not a backup flag corresponding to the game history control module is set in the SRAM 99 (backup RAM) (Sn6-1). In this embodiment, in St0-5, St5, St10, St15 in the power interruption process (sub) of FIG. 36, a backup flag is set for each program module when a power interruption occurs. That is, in this embodiment, regarding the processing performed by the sub-control unit 91, the backup flag corresponds to the backup flag corresponding to the game history control module, the backup flag corresponding to the sound / LED control module, and the AT control module. There are four types of backup flags and backup flags corresponding to the image control module. In Sn6-1, the sub-control unit 91 first checks whether or not a backup flag corresponding to the game history control module is set.

  If the backup flag corresponding to the game history control module is not set, an initialization process for initializing all storage areas of the RAM 91c (work RAM) and SRAM 99 (backup RAM) is executed (Sn20). When the backup flag corresponding to the game history control module is set, the backup flag is cleared (Sn6-2). After clearing the backup flag, a checksum is calculated by obtaining an exclusive OR of data in an area where data used in the game history control module of the SRAM 99 (backup RAM) is stored (Sn6-3). Thereafter, it is determined whether or not the calculated checksum matches the backed-up checksum (Sn6-4). In this embodiment, in St0-4, St4, St9, and St14 in the power interruption process (sub) of FIG. 36, the checksum is also used for each program module when a power interruption occurs. Is generated by obtaining an exclusive OR of the data to be stored in the SRAM 99 (backup RAM). That is, in this embodiment, regarding the processing performed by the sub-control unit 91, the checksum includes a checksum calculated using data used in the game history control module and data used in the sound / LED control module. There are four types: a checksum calculated using the data, a checksum calculated using data used in the AT control module, and a checksum calculated using data used in the image control module . In Sn6-4, the sub-control unit 91 first confirms whether or not the checksum calculated using the data used in the game history control module matches that being backed up.

  If the checksums do not match, initialization processing for initializing all storage areas of the RAM 91c (work RAM) and SRAM 99 (backup RAM) is executed (Sn20). If the checksums match, it is determined whether or not a backup flag corresponding to the sound / LED control module is set in the SRAM 99 (backup RAM) (Sn6-5). If the backup flag corresponding to the AT control module is not set, initialization processing for initializing all storage areas of the RAM 91c (work RAM) and SRAM 99 (backup RAM) is executed (Sn20). If the backup flag corresponding to the sound / LED control module is set, the backup flag is cleared (Sn7). After clearing the backup flag corresponding to the sound / LED control module, the exclusive sum of the data of the SRAM 99 (backup RAM) in which the data used in the sound / LED control module is stored is obtained to calculate the checksum ( Sn8). Thereafter, it is determined whether or not the calculated checksum matches the backed-up checksum (Sn9). If the checksums do not match, initialization processing for initializing all storage areas of the RAM 91c (work RAM) and SRAM 99 (backup RAM) is executed (Sn20).

  If the checksums match, it is determined whether a backup flag corresponding to the AT control module is set in the SRAM 99 (backup RAM) (Sn10). If the backup flag corresponding to the AT control module is not set, initialization processing for initializing all storage areas of the RAM 91c (work RAM) and SRAM 99 (backup RAM) is executed (Sns20). If the backup flag corresponding to the AT control module is set, the backup flag is cleared (Sn11). After the backup flag corresponding to the AT control module is cleared, an exclusive OR of the data of the SRAM 99 (backup RAM) in which the data used in the AT control module is stored is obtained to calculate the checksum (Sn12). Thereafter, it is determined whether or not the calculated checksum matches the backed-up checksum (Sn13). If the checksums do not match, initialization processing for initializing all storage areas of the RAM 91c (work RAM) and SRAM 99 (backup RAM) is executed (Sn20).

  If the checksums match, it is determined whether a backup flag corresponding to the image control module is set in the SRAM 99 (backup RAM) (Sn14). When the backup flag corresponding to the image control module is not set, initialization processing for initializing all storage areas of the RAM 91c (work RAM) and SRAM 99 (backup RAM) is executed (Sn20). If the backup flag corresponding to the image control module is set, the backup flag is cleared (Sn15). After clearing the backup flag corresponding to the image control module, the exclusive sum of the data in the area of the SRAM 99 (backup RAM) where the data used by the image control module is stored is obtained to calculate the checksum (Sn16). Thereafter, it is determined whether or not the calculated checksum matches the backed-up checksum (Sn17). If the checksums do not match, initialization processing for initializing all storage areas of the RAM 91c (work RAM) and SRAM 99 (backup RAM) is executed (Sn20).

  If the checksums match, it is determined whether the setting change command reception flag is set (Sn18). If the command change flag during setting change is not set, a return process is executed (Sn19). On the other hand, if the setting change command reception flag is set, initialization processing for initializing all storage areas of the RAM 91c (work RAM) and SRAM 99 (backup RAM) is executed (Sn20). After the process of Sn19 or Sn20 is completed, the timer interrupt process (sub) shown in FIG. 24 is performed according to the timer interrupt.

  As described above, in the startup process (sub), the return process is performed on the condition that all checksums of the program modules match and the backup flags for the program modules are all set. It is possible to prevent the restoration process from being performed even though the module backup data is not accurate. As a result, even if backup data is created for each module, the restoration process can be performed reliably.

  FIG. 24 is a flowchart of timer interrupt processing (sub) executed by the CPU 91c at intervals of 1.12 seconds based on the count value of the internal clock.

  In the timer interrupt process (sub), first, the register in use is saved in the stack area (Sp1).

  Next, a power failure determination process is performed (Sp2). In the power failure determination process, it is determined whether or not a voltage drop signal is input from the power failure detection circuit 48. If a voltage drop signal is input, whether or not the voltage drop signal is input in the previous power failure determination process as well. If a voltage drop signal has been input in the previous power failure determination process, it is determined that a power failure has occurred, and a power interruption flag indicating that is set.

  After the power failure determination process in the step of Sp2, it is determined whether or not the power interruption flag is set (Sp3). If the power interruption flag is set, the process proceeds to a power interruption process (sub) described later. .

  If the power interruption flag is not set, command analysis processing is executed (Sp4). In the command analysis process, it is determined whether or not a command is stored in the command buffer. If the command is stored in the command buffer, the command is acquired from the command buffer. And the process according to the acquired command is performed.

  After the command analysis process is completed, the sound / LED control process is executed based on the sound / LED control module (Sp5). The sound / LED control process in the step of Sp5 is a process executed by the sub-control unit 91 according to the sound / LED control module. In the sound / LED control process, control related to the effect effect LED 52, the speakers 53, 54, and the reel LED 55 is performed according to the progress of the game.

  After the sound / LED control process is completed, the AT control process is executed based on the AT control module (Sp6). The AT control process in the step of Sp6 is executed by the sub-control unit 91 according to the AT control module, and is a process for controlling the effect state to the AT according to the gaming state or the like.

[AT lottery processing]
The sub-control unit 91 performs an AT lottery to determine whether or not to control the AT by executing an AT lottery process included in the AT control process. In the AT lottery process, it is determined based on a command from the main control unit 41 whether or not a predetermined AT lottery condition is satisfied, and when the AT lottery is satisfied, the AT lottery is executed. The AT lottery includes an AT game grant lottery for determining whether or not to grant an AT game number, and an AT game number lottery for determining the number of AT games to be granted.

  The number of AT games indicates a period (number of games) that can be controlled by the AT. The number of AT games is consumed (subtracted) every time the game is consumed, and is controlled by the AT until the game corresponding to the number of AT games is consumed, during which the navigation effect can be executed. For this reason, it can be said that the greater the number of AT games determined, the higher the degree of advantage for the player because the AT is controlled over a longer period.

  FIG. 26 is a diagram for explaining an example of an AT lottery condition that triggers execution of AT lottery. FIG. 27 is a diagram for explaining an example of the AT lottery when the AT lottery condition is satisfied. FIG. 28 is a diagram for explaining an example of a table referred to in the AT game number lottery among the AT lotteries.

  As the AT lottery conditions, as shown in FIG. 26, first and second conditions are set. The first AT lottery condition is satisfied by winning a weak cherry or a middle cherry when the gaming state is RT0-4. When the first AT lottery condition is satisfied, an AT game grant lottery is performed as an AT lottery. Note that the first AT lottery condition may be established by winning a cherry (excluding a winning mode when winning a strong cherry).

  Referring to FIG. 27, in the AT game giving lottery when the first AT lottery condition is satisfied, it is determined that the number of AT games is given with a probability of 2%. Note that the AT game grant lottery is randomly determined according to the set probability using, for example, random numbers.

  The second AT lottery condition is satisfied by winning a strong cherry when the gaming state is RT0 to 4, or by ending BB or RB. The second AT lottery condition is satisfied when the cherry stops at the lower stage of the left reel 2L and the combination of “BAR-BAR-any” is arranged at the middle stage instead of winning the strong cherry. May be. When the second AT lottery condition is satisfied, an AT game giving lottery is performed as the AT lottery. In the AT game giving lottery when the second AT lottery condition is satisfied, it is determined that the number of AT games is given with a probability of 10%.

  When the first AT lottery condition is satisfied and the player wins in the AT game grant lottery, the AT game number lottery is performed according to the distribution rate at the time of the first determination shown in FIG. When the second AT lottery condition is satisfied and the game is won in the AT game grant lottery, the AT game number lottery is performed according to the distribution rate at the time of the second determination shown in FIG.

  When the allocation rate at the time of the first determination shown in FIG. 28 is referred, the number of AT games is determined to be 50 at a rate of 60%, the number of AT games is determined to be 100 at a rate of 25%, and the rate of 10% Thus, the AT game number lottery is performed so that the AT game number is determined to be 150 and the AT game number is determined to be 200 at a rate of 5%.

  Therefore, according to the allocation rate at the time of the first determination, the expected number of AT games that can be expected to be obtained in one AT lottery is 80 (= 50 × 60%) from the sum of the number of AT games × the winning rate. + 100 × 25% + 150 × 10% + 200 × 5%).

  When the allocation rate at the time of the second determination shown in FIG. 28 is referred to, the AT game number is determined to be one of 50, 100, 150, 200, and 250 at a rate of 20% each. A lottery of games will be held.

  Therefore, according to the allocation rate at the time of the second determination, the expected number of AT games that can be expected to be obtained in one AT lottery is 150 (= 50 × 20%) from the sum of the number of AT games × the winning rate. + 100 × 20% + 150 × 20% + 200 × 20% + 250 × 20%).

  For this reason, when a weak cherry, a middle cherry, or a strong cherry is won, the probability of winning an AT and the probability determined by a larger number of AT games is higher in the strong cherry than in the middle cherry and the weak cherry.

  The sub-control unit 91 specifies, for example, whether the gaming state is RT0 to 4 or when BB or RB is ended based on the gaming state command from the main control unit 41, Based on the winning command, it is specified whether a weak cherry, middle cherry, or strong cherry is won.

  As described above, in this embodiment, whether or not the AT lottery condition is satisfied is determined by the AT lottery process performed by the sub-control unit 91. When the AT lottery condition is satisfied, the AT lottery is performed.

  The sub-control unit 91 stores an AT flag indicating the AT and the number of AT games in a predetermined area of the RAM 91c when it is determined to give the number of AT games in the AT lottery. In addition, when a determination is made to give the number of AT games in a state in which the AT flag indicating AT is already set, the determined number of AT games is added and added. Based on the AT flag in the RAM 91c, the sub-control unit 91 specifies whether or not to control the AT and specifies the number of remaining AT games. When the AT flag indicating AT is set, the number of AT games is consumed and the AT can be controlled.

[AT management processing]
The sub-control unit 91 manages the control to the AT based on the AT flag by performing the AT management process included in the AT control process when the gaming state is RT0-3.

  Specifically, when the AT flag indicating the AT win is set when the gaming state is RT0 to 3, the sub-control unit 91 controls the AT after a precursor effect and a battle effect to be described later are executed. Of RT0 to RT0, RT0, RT2, and RT3 other than RT1 consume (subtract) the number of AT games by 1 every time the game is consumed. In this way, the state controlled by AT in RT0, RT2, RT3 is also referred to as ART.

  In RT1, the navigation effect can be executed under the control of the AT without consuming (subtracting) the number of AT games. Even in this case, as shown in the RT1 column of FIG. 19, the payout rate at RT1 is low, so even if a navigation effect is executed at RT1, the player's hand medal will not increase.

  Further, when the bonus is selected during the AT and the RT0 is controlled to the internal 1 or the internal 2 RT0, the control to the AT is continued in the internal. In the inside, the navigation effect can be executed under the control of the AT without consuming (subtracting) the number of AT games.

  Further, the sub-control unit 91 performs AT management processing, and subtracts 1 from the number of AT games each time one game is consumed in the case of ART.

  While being controlled by the AT, a corresponding navigation effect is executed in the game won for the navigation target role corresponding to the gaming state. The navigation target combination is replay GR1 to 6 when it is normal · RT1, replay GR11 to 16 and replay GR21 to 25 when it is normal · RT0, and replay GR31 to 36 when it is normal · RT2. Further, in normal / RT0 to RT3, the push order bell is a common navigation target combination.

  As a navigation effect when winning replays GR1 to GR36, a push order for winning a promotion replay, special replay, or SP replay according to the winning situation is notified. For example, a message “left middle right!” Is displayed on the liquid crystal display 51 as a navigation effect when the replay GR1 is won. Regarding the other replays GR <b> 2 to 36, a message corresponding to the replay GR is displayed on the liquid crystal display 51.

  Further, as a navigation effect when one of the push order bells is won, a push order for reliably winning the right-down bell or the middle bell is notified. For example, when winning the left bell, the left reel is stopped as the first stop reel, so that the right falling bell can be reliably won, so “left!” For stopping the left reel as the first stop reel. Is displayed on the liquid crystal display 51. As for the middle bell and the right bell, a message corresponding to each bell is displayed on the liquid crystal display 51.

  As described above, in the navigation effect according to the present embodiment, a message reminiscent of an operation mode (operation procedure) advantageous to the player is notified in the same mode regardless of the type of the navigation target role. For this reason, the player can operate in an operation mode that is advantageous to the player without being conscious of the type of the winning navigation target combination.

  In addition, the aspect of a navigation effect is not restricted to such an aspect, What kind of thing may be sufficient if a player is distinguishable according to a winning condition. In addition, the navigation effect is not limited to what is displayed on the liquid crystal display 51, and may be executed using the effect effect LED 52, the speakers 53 and 54, the reel LED 55, and the like.

  Then, by executing the navigation effect, it is possible to make the promotion replay winning, the special replay winning, the SP replay winning, the bell winning selected intentionally, and avoid the falling replay winning.

  If the number of AT games is 0, the AT flag is updated to indicate that it is not an AT. That is, a series of AT end conditions are satisfied when the number of AT games becomes zero. After the number of AT games becomes 0, in principle, the navigation effect is not executed until the number of AT games is set again. As a result, it becomes difficult to maintain RT0, RT2, and RT3, and the possibility that a game is played at RT1 increases.

  In this embodiment, even when the AT flag indicating AT winning is set, the bonus is not controlled by the AT and the navigation effect is not executed during the bonus. Further, in this embodiment, the AT is continued until the bonus winning, but the continuous control to the AT is an average increase / decrease number per game when the AT is controlled in the internal RT controlled by winning the bonus. It may be limited to the case where becomes 0 or less. As a result, it is possible to prevent the occurrence of inconvenience that the profit of the player is increased by intentionally prolonging the period of RT0 in the interior and AT. Further, when the average number of increase / decrease per game when it is controlled by AT at RT0 inside is larger than 0, AT is continued until the bonus is won, and it is not controlled by AT at RT0 inside. It may be configured.

  As described above, when one of RT0, RT2, and RT3, it is controlled to ART while the number of AT games is consumed by consuming one AT game number. Thus, it can be said that the AT can be controlled over a period corresponding to the number of AT games set according to the result of the AT lottery.

  Returning to FIG. 25, after the AT control process is completed, the image control process is executed based on the image control module (Sp7). The image control process in the step of Sp7 is a process executed by the sub control unit 91 according to the image control module. In the image control process, for example, control related to display of various images displayed from the liquid crystal display 51 such as demonstration display and effect display is performed.

[Battle-related production lottery processing]
The sub control unit 91 executes a battle related effect lottery process included in the image control process. In the battle-related effect lottery process, when a battle effect is executed, an enemy character (hereinafter also referred to as a battle character) that battles with an ally character in the battle effect is determined, and a predetermined time until the battle effect is started is determined. The contents of the effect to be executed in the precursor period (during 5 games) are determined.

  The battle effect refers to an effect that asks whether or not to acquire (grant or add) the number of AT games. In the liquid crystal display 51, a player character and a battle character are used for a plurality of games (for example, five games). After performing an effect of developing a predetermined battle, as an outcome of the battle, an effect that informs that the number of AT games cannot be obtained if the ally character is defeated, and informs that the number of AT games is obtained if the ally character wins Say. In the battle effect, the physical strength points of the teammate character and the battle character vary depending on the content of the battle effect. For this reason, it can be said that the physical strength points and the content of the battle effect of each of the teammate character and the battle character during the battle effect are effects that indirectly inform the degree of expectation for acquiring the number of AT games.

  The precursor period is a period over a plurality of games (for example, five games) until a battle effect is executed. In the precursor period, the liquid crystal display 51 performs a precursor effect for informing information related to the enemy character.

  The sign effect suggests that, for each enemy character that has a possibility of playing against a friendly character in the battle effect, the friendly character may win if it is played against the enemy character, and any character can be played. This is a directing to suggest whether the nature is high.

  The possibility that the teammate character will win is performed, for example, by displaying “winning side” as a percentage for each enemy character. If the ally wins is high (for example, “90%” is displayed), it can be said that the teammate character is highly likely to win. On the other hand, it can be said that if the teammate has a low win (for example, when “20%” is displayed), the teammate character is less likely to win.

  Further, which character is highly likely to play against is suggested by, for example, the content of a statement from an enemy character. For example, if the content is such as “I ’ll do it with you”, “I ’m in good condition”, “I ’d like to change”, etc., this suggests that the character is likely to be selected as an enemy character On the other hand, if it is a statement such as “I quit this time”, “I am not motivated”, “I am tired”, etc., this suggests that there is a low possibility that the character will be selected as an enemy character. It can be said that.

  Since the degree of expectation that the teammate character wins in the battle effect varies depending on the enemy character, the precursor effect can be said to be an effect that indirectly informs the magnitude of the expectation for acquiring the number of AT games.

  In addition, during the precursor period, a suggestion effect for suggesting the possibility that the content suggested by the precursor effect is switched to a precursor effect that suggests a content with a higher expectation level for the player is performed.

  The suggestion effect is performed, for example, by displaying a message such as “power up” while the pattern of the character displayed during the precursor period becomes a specific pattern (such as a cherry blossom pattern). By executing the suggestion effect, the possibility that the teammate character wins can be increased, and it can be suggested to the player that the player can switch to the sign effect that suggests the content that is more expected for the player.

  FIG. 29 is a flowchart for explaining a battle related effect lottery process. In S01, it is determined whether or not the AT lottery condition shown in FIG. 26 is satisfied. When it is determined that the AT lottery condition is not satisfied, the battle related effect lottery process is ended as it is. On the other hand, when it is determined that the AT lottery condition is satisfied, a sign effect execution lottery related to the execution of the sign effect is performed in S02. In the sign production execution lottery, it is determined which of “a no sign production” that does not execute the sign production or a plurality of types of sign production is executed. Patterns A to F are defined as a plurality of types of precursor effects in the present embodiment.

  FIG. 30 is a diagram for explaining the sign effect lottery table referred to in the sign effect execution lottery. In the sign effect lottery table, different distribution ratios are determined depending on whether or not the AT is won.

  If the AT lottery condition is met and the AT is not won, it is determined as “no sign effect” with a probability of 84%, and the remaining probability is determined as one of a plurality of types of patterns A to F. . As shown in FIG. 30, pattern A has a probability of 6%, pattern B has a probability of 5%, pattern B has a probability of 4%, pattern C has a probability of 3%, and pattern D has a probability of 2%. However, the pattern F is determined as a precursor effect to be executed with a probability of 1%.

  On the other hand, when the AT is selected due to the establishment of the current AT lottery condition, it is determined as “no precursor effect” with a probability of 4%, but among the remaining 96% of the patterns A to F determined in plural types Decide on either. As shown in FIG. 30, pattern A has a probability of 3%, pattern B has a probability of 10%, pattern C has a probability of 15%, pattern D has a probability of 18%, and pattern E has a probability of 23%. However, the pattern F is determined as a precursor effect to be executed with a probability of 27%.

  Here, when the AT winning time is compared with the AT non-winning time, the distribution rate is determined so that the sign effect is executed with a higher probability when the AT is winning than when the AT is not winning. For this reason, when the precursor effect is executed, it is possible to have a sense of expectation for winning the AT, compared to when the precursor effect is not executed.

  Also, even when the warning effect is executed, the pattern F is determined with the lowest probability among the warning effect patterns when the AT is not won, whereas it is the highest of the warning effect patterns when the AT is won. Determined by probability. That is, when the precursor effect by the pattern F is executed, the AT winning ratio is higher than when the precursor effect by another pattern is executed. For this reason, when the precursor effect is executed by the pattern F, the greatest expectation can be given to having won the AT.

  In addition, when the precursor effect is executed, the AT winning ratio is the highest in pattern F, followed by patterns E, D, C, and B, and the lowest in pattern A. As a result, even when the precursor effect is executed, it is possible to vary the sense of expectation that the player can have with respect to having won the AT, depending on which pattern it is.

  Next, with reference to FIG. 31, the patterns A to F defined as the precursor effects will be described. FIG. 31 is a diagram for explaining the content of each of the precursor effect patterns A to F. When the sign effect is roughly divided every 1 to 5 games, either the a system effect or the b system effect is executed. The combinations of effects determined for each of the 1 to 5 games are determined in accordance with the sign effect pattern.

  The a system effect means an effect that suggests that the degree of expectation for winning the AT is low, for example, an effect that suggests that the opponent will play against the enemy character with the lower win. On the other hand, the production of the b system means an effect that suggests that the degree of expectation for winning the AT is high, for example, an effect that suggests that the opponent wins a higher enemy character. Say. In FIG. 31, the a system effect is indicated as “a” and the b system effect is indicated as “b”.

  The pattern A is a pattern in which the a system effect is executed in the second game to the fifth game after the a system effect is executed in the first game. That is, in the pattern A, the effect is not switched to the b system effect. On the other hand, the pattern A has the lowest ratio executed at the time of AT winning as described above. For this reason, when the warning effect by the pattern A is executed, it can be suggested that the degree of expectation for winning the AT is low even from the content of the effect that is not switched to the effect of the b system.

  The pattern B is a pattern that is executed by switching to the b system effect in the fifth game after executing the a system effect in the first game to the fourth game. Similar to Pattern B, Patterns C to E are the subsequent games after performing the effects of system a until Pattern C is played up to the third game, Pattern D is played up to the second game, and Pattern E is played up to the first game, respectively. Is a pattern executed by switching to the b system effect. As described above, the patterns B to E are selected so that the ratios executed at the time of winning the AT are in the order of E, D, C, and B. Also, the timing of switching to the b system effect in the order of the patterns E, D, C, and B is early. For this reason, when the precursor effect is started by the effect of the a system, it is possible to have an expectation for switching to the effect of the b system at an earlier stage.

  The pattern F is a pattern in which the b system effect is executed from the first game and the b system effect is continuously executed up to the fifth game. On the other hand, the pattern F has the highest ratio executed at the time of AT winning as described above. For this reason, it can be suggested that there is a high degree of expectation for the fact that the AT has been won since the indication effect by the pattern F is started.

  As described above, the patterns A to F of the indication effects are different in the combination of effects executed for every 1 to 5 games, and the patterns B to E are different in the switching game to be switched from the effects of the system a to the effects of the system b. It is prescribed as follows. The switching game corresponds to the fifth game if it is pattern B, corresponds to the fourth game if it is pattern C, and corresponds to the third or second game if it is pattern D or E.

  It should be noted that the a-line and b-line effects constituting the precursor effect are not limited to one type, but may be determined in a plurality of types, and the effects constituting the precursor effect Is not limited to one composed of two effects, but may include, for example, an effect in which the winner of an ally is unknown (50%).

  Returning to FIG. 29, in S03, it is determined whether or not it is determined in S02 that the sign effect is to be executed. When it is determined that the sign effect is not determined, the battle related effect lottery process is terminated.

  On the other hand, when it is determined that execution of the precursor effect is determined, is the pattern of the determined precursor effect one of patterns B to E switched from the a-system effect to the b-system effect? Determine.

  When it is determined that none of the patterns B to E is reached, the process proceeds to S06. On the other hand, when it is determined that the pattern is one of the patterns B to E, in S05, a switching timing lottery is performed in which the timing for switching from the a-line effect to the b-line effect is lottered in the switching game.

  FIG. 32 is a diagram for explaining a switching timing lottery table referred to in the switching timing lottery. The switching timing lottery table has different distribution ratios depending on which of the patterns B to E is selected and whether or not the AT is won.

  FIG. 32A is a switching timing lottery table that is referred to when the pattern B is determined. If the AT lottery condition is met and the AT is not won, the game is determined with a probability of 60% at the start of the game, the probability of 30% is determined at the time of the first stop, and the probability of 10%. It is determined at the time of the third stop. On the other hand, when the AT winning lottery condition is established, the game is determined as “at the start of game” with a probability of 20%, determined as “at the time of first stop” with a probability of 29%, and with a probability of 1%. It is determined at “second stop” and is determined at “third stop” with a probability of 50%.

  In other words, the third stop time is determined with the lowest probability when the AT is not won, whereas it is determined with the highest probability when the AT is won. For this reason, even when the presentation is switched in the fifth game, the expectation for winning the AT can be made different depending on the timing at which the fifth game is switched. When switched, the expectation can be maximized. Further, at the time of the second stop, it is selected only when the AT is won and with a very low probability. For this reason, when it is switched at the time of the second stop of the fifth game, it can be indirectly notified that the AT is won premierly.

  FIG. 32B is a switching timing lottery table that is referred to when the pattern C or the pattern D is determined. If the AT lottery condition is met and the AT is not won, the game is determined with a probability of 30% at the time of “game start”, with a probability of 20% and determined at the “first stop” with a probability of 20%. It is determined at “second stop” and is determined at “third stop” with a probability of 30%. On the other hand, when the AT winning lottery condition is established, the game is determined as “at the start of the game” with a probability of 20%, determined as “at the first stop” with a probability of 30%, and with a probability of 30%. It is determined at “second stop” and is determined at “third stop” with a probability of 20%.

  That is, the first stop time or the second stop time is determined with a low probability when the AT is not won, whereas it is determined with a high probability when the AT is won. For this reason, even when the production is switched in the third game or the fourth game, the expectation for winning the AT can be made different depending on at which timing it is switched. A feeling of expectation can be further enhanced when switched at the second stop.

  FIG. 32C is a switching timing lottery table that is referred to when the pattern E is determined. When the AT lottery condition is met and the AT is not won, the game is determined to be “at the start of game” with a probability of 5%, “at the time of first stop” with a probability of 45%, and “ It is determined at “second stop” and is determined at “third stop” with a probability of 10%. On the other hand, if the AT lottery condition is established and the AT is won, the game is determined with “40% probability” at the time of “game start”, 25% with the probability of “first stop”, and with the probability of 25%. It is determined at “second stop” and is determined at “third stop” with a probability of 10%.

  That is, the game start time is determined with the lowest probability when the AT is not won, whereas it is determined with the highest probability when the AT is won. For this reason, even when the production is switched in the second game, the expectation of winning the AT can be made different depending on at which timing it is switched, and the expectation is made when the game is switched at the start of the game. The feeling can be enhanced most.

  Returning to FIG. 29, in S06, a suggestion effect lottery related to the execution of the suggestion effect is performed. In the suggestion effect lottery, it is determined whether the suggestion effect is not executed “no suggestion effect” or when it is executed. The suggestion effect in the present embodiment is executed in any game up to one game before the switching game when any precursor effect of the patterns A to E is executed.

  FIG. 33 is a diagram for explaining the suggestion effect lottery table referred to in the suggestion effect lottery. In the suggestion effect lottery table, different distribution ratios are determined depending on which pattern is determined as the precursor effect, and whether the established AT lottery condition is first or second.

  When the first AT lottery condition is established and it is determined as a precursor effect of the pattern A with no switching game, as shown in FIG. 33A, it is determined as “no suggestive effect” with a probability of 84%, Of the remaining probabilities, “first game” and “second game” are each determined with a probability of 2%, and “third game”, “fourth game”, and “fifth game” have a probability of 4% each. Determined by

  When the second AT lottery condition is established and it is determined to be a precursor effect of the pattern A with no switching game, as shown in FIG. 33 (a), it is determined as “no suggestive effect” with a probability of 89%, Of the remaining probabilities, “first game”, “second game”, and “third game” are each determined with a probability of 3%, and “fourth game” and “fifth game” are each with a probability of 1%. Determined by

  When the first AT lottery condition is satisfied and the switching game is determined to be the precursor effect of the fifth game, Pattern B, as shown in FIG. 33B, “no suggestive effect” with a probability of 76% Of the remaining probabilities, “1st game” and “2nd game” are each determined with a probability of 5%, and “3rd game” and “4th game” are respectively determined with a probability of 7%. The

  When the second AT lottery condition is established and the switching game is determined to be the precursor effect of the fifth game, Pattern B, as shown in FIG. 33B, “no suggestive effect” with a probability of 72% Of the remaining probabilities, “1st game” and “2nd game” are each determined with a probability of 8%, and “3rd game” and “4th game” are respectively determined with a probability of 6%. The

  When the first AT lottery condition is established and the switching game is determined to be a precursor effect of the fourth game pattern C, as shown in FIG. 33 (c), “no suggestive effect” with a probability of 70%. Of the remaining probabilities, “1st game” is determined with a probability of 8%, “2nd game” is determined with a probability of 10%, and “3rd game” is determined with a probability of 12%. The

  When the second AT lottery condition is satisfied and the switching game is determined to be the precursor effect of the fourth game pattern C, as shown in FIG. 33 (c), “no suggestive effect” with a probability of 64% Of the remaining probabilities, the “first game” is determined with a probability of 14%, the “second game” is determined with a probability of 12%, and the “third game” is determined with a probability of 10%. The

  When the first AT lottery condition is established and the switching game is determined to be the precursor effect of the third game pattern D, as shown in FIG. 33 (d), “no suggestive effect” with a probability of 50%. Of the remaining probabilities, the “first game” is determined with a probability of 23%, and the “second game” is determined with a probability of 27%.

  When the second AT lottery condition is satisfied and the switching game is determined to be the precursor effect of the third game D, as shown in FIG. 33 (d), “no suggestive effect” with a probability of 30%. Of the remaining probabilities, “first game” is determined with a probability of 45%, and “second game” is determined with a probability of 25%.

  When the first AT lottery condition is established and the switching game is determined to be the precursor effect of the second game pattern E, as shown in FIG. 33 (e), “no suggestive effect” with a probability of 20%. The “first game” is determined with a probability of 80%.

  When the second AT lottery condition is established and the switching game is determined to be the precursor effect of the second game pattern E, as shown in FIG. 33 (e), “no suggestive effect” with a probability of 5%. The “first game” is determined with a probability of 95%.

  As described above, in the suggestion effect lottery, it is determined that the suggestion effect is to be executed according to the distribution ratio according to whether or not the type of the sign effect is determined. Further, the rate at which the suggestion effect is executed is set so that the pattern E is the highest when it is determined, the patterns D, C, and B are lower in this order, and the pattern A is determined the lowest. As described above, the expectation that the player can have for winning the AT is the highest in pattern E among patterns A to E, and the lower in the order of patterns D, C, and B. Pattern A is the lowest. For this reason, when the suggestion effect is executed, the player feels that the pattern B to E is switched from the a-line effect to the b-line effect, and that the player has won the AT. The expectation that can be held can be improved.

  In the suggestion effect lottery, it is determined that the suggestion effect is executed according to a different distribution ratio depending on whether the established AT lottery condition is the first or the second. As shown in FIG. 27, a higher number of games is given as the number of AT games at a higher rate when the established AT lottery condition is second than when it is first. For this reason, by performing the suggestion effect, the expectation for not only winning the AT but also a greater number of AT games, that is, a privilege with a higher degree of advantage for the player, is improved. Can do.

  Further, in the suggestion effect lottery, a faster game is determined as a game for executing the suggestion effect at a higher ratio when the second AT condition is satisfied than when the established AT lottery condition is first. For this reason, even when the suggestion effect is executed, the expectation that the AT has been won differs depending on the game number of the game in which the suggestion effect was executed, and It is possible to make the player have a greater expectation when the suggestive effect is executed at an earlier stage in the period.

  Returning to FIG. 29, in S07, a battle character lottery is performed in which a battle character that is an enemy character to be battled with an ally character is drawn in a battle effect.

  FIG. 34 is a diagram for explaining a battle character lottery table referred to in the battle character lottery. In the battle character lottery table, different distribution ratios are determined depending on whether or not the determined sign effect pattern is the pattern A that does not result in the b system effect, and whether or not the AT is won.

  FIG. 34A is a battle character lottery table that is referred to when the pattern A is determined. If the AT lottery condition is met and AT is not won, it is determined as “Character A” with a probability of 95%, and is determined as “Character B” with a probability of 5%. On the other hand, if the current AT lottery condition is met and the AT is won, it is determined as “Character A” with a probability of 40% and is determined as “Character B” with a probability of 60%.

  For this reason, when the character A suggested by the pattern A is determined as a battle effect battle character after the pattern A is executed, it is suggested that there is a high possibility that the AT is not won. When a character B different from the character A suggested by A is determined, it can be suggested that there is a higher possibility of winning the AT than when the character A is determined. As a result, the battle character for the battle effect after the pattern A is executed is more likely to be expected to win the AT when it becomes the character B than when it becomes the character A. Can do.

  FIG. 34B is a battle character lottery table which is referred to when any of the patterns B to F is determined. If the AT lottery condition is met and the AT is not won, it is determined as “Character A” with a probability of 40%, and is determined as “Character B” with a probability of 60%. On the other hand, if the current AT lottery condition is satisfied and the AT is won, it is determined as “Character A” with a probability of 5% and is determined as “Character B” with a probability of 95%.

  For this reason, when the character B suggested by the patterns B to F is determined as a battle effect battle character after any of the patterns B to F is executed, the AT winning is performed more than when the character A is determined. It can be suggested that there is a high possibility that As a result, it is expected that when the character B becomes a character B rather than the character A as a battle effect battle character after any of the patterns B to F is executed. It can make you feel.

  Returning to FIG. 29, in S08, effect data for executing the effects determined in S02, S05, S06, and S07 is set in the RAM 91c, and the battle-related effect lottery process is terminated.

  As described above, when the battle effect is executed, in the lottery in S02, S05, S06, and S07 in FIG. 29, the effect content related to the sign effect or the battle effect is determined and determined based on the lottery result. Production data for executing the produced production content is set in S08 of FIG. In the effect data set in S08, data for specifying the type of predictive effect to be executed when executing the predictor effect, and a switching timing for switching from the a-line effect to the b-line effect in the switching game are specified. Data for specifying the timing for executing the suggestion effect in the case of executing the suggestion effect, and data for specifying the type of the battle character. The precursor effect, suggestion effect, and battle effect executed based on these data are collectively referred to as a battle-related effect.

[Battle related effects execution processing]
The sub-control unit 91 executes the battle-related effect execution process included in the image control process, thereby executing the effect content set as the battle-related effect at a predetermined timing. Here, an example of a battle related effect will be described with reference to FIG. FIG. 35 is a diagram for explaining an example of a battle-related effect. As shown in FIG. 35, the battle-related effect is executed on the liquid crystal display 51, and is also executed using the effect effect LED 52, the speakers 53 and 54, the reel LED 55, and the like. In FIG. 35, the pattern C of the fourth game is set as the warning effect, the game start time is set as the switching timing, the execution of the suggestion effect is set as the second game, and the battle character is the battle character. A case where the character B is set will be described as an example.

  First, when the first game of the precursor period is started, it is notified that the precursor period has started. In FIG. 35A, messages such as “battle preparation mode” and “art is confirmed if the character AorB is defeated!” Are displayed. Thereby, it is possible to notify the player that the precursor period has started, and thereafter, information regarding enemy characters is notified over five games.

  After the performance shown in FIG. 35A is performed in the first game in the precursor period, a character that can be selected as a battle character is notified. In FIG. 35 (b), a character image reminiscent of an old man with a martial art is displayed corresponding to the character A of FIG. 15, and a character image reminiscent of a giant boxer is displayed corresponding to the character B. In the first game in the pattern C, the a system effect is executed, so that the character A is displayed larger than the character B, and the character A issues a message “I will do it”. “I'll stop this time”. Thereby, it is suggested that the possibility that the character A is selected as the battle character in the battle effect is high.

  Further, “20%” is displayed under the character A, and “50%” is displayed under the character B as the win of the teammate character. Thereby, it can be suggested that when the character B is selected as the battle character rather than the character A, there is a high possibility that the teammate character wins in the battle effect and is notified that the AT has been acquired.

  As described above, in the slot machine 1 according to the present embodiment, the size of the enemy character and the content of the remark indicate the possibility of becoming a battle character in the battle production, and the battle character is determined from the win value of the teammate. The possibility that the ally character wins in the battle effect is suggested, and the combination of them indirectly suggests the possibility and expectation of the ally character winning in the subsequent battle effect.

  Furthermore, after the performance shown in FIG. 35 (b) is performed in the first game in the precursor period (for example, at the time of the third stop), the teammate character is displayed as shown in FIG. 35 (c). , "If you don't have special training" message is displayed. As described above, the effects shown in FIGS. 35B and 35C suggest that the degree of expectation for winning the AT is low. Note that FIGS. 35B and 35C are examples of effects of the a system.

  In the second game in the precursor period, characters that are highly likely to be selected as battle characters are continuously suggested. In the pattern C, the a-system effects are also executed in the second game. In FIG. 35D, the character A is displayed larger than the character B, the message that the character A is “good”, and the character B that is “not motivated” is issued. Thereby, it is suggested that the possibility that the character A is selected as the battle character in the battle effect is high.

  On the other hand, the win of the teammate character has not changed since the first game, and it is notified that the character B has been selected as the battle character rather than the character A, and the teammate character has won the battle and won AT. It continues to be suggested that this is likely.

  Further, after the performance shown in FIG. 35D is performed in the second game in the precursor period (for example, at the time of the third stop), as shown in FIG. 35C, as shown in FIG. The ally character is displayed. However, FIG. 35 is an example in which the suggestive effect is executed in the second game as described above. For this reason, in FIG. 35 (e), the pattern changes to a cherry blossom pattern (striped pattern in FIG. 35) and a friendly character covered with flames is displayed, and a message such as “power up” is displayed. The suggestion effect is executed. This gives a sense of expectation that the sign production will be switched to the production of the b system, increases the possibility that the ally character will win in the subsequent battle production, and suggests more content that is highly expected for the player It is possible to suggest to the player that there is a high possibility of switching to the precursor effect. Note that the display of the teammate character in FIGS. 35 (d) and 35 (e) is an example of the production of the a system. In FIG. 35 (e), the change in the pattern / mode of the teammate character and the message “power up” are displayed. The display is an example of a suggestion effect.

  In the third game in the precursor period, characters that are likely to be selected as battle characters are continuously suggested. In pattern C, the a-game effects are also executed in the third game. Thus, in FIG. 35 (f), the character A is displayed larger than the character B, the message saying that the character A is “good”, and the character B saying “I'm not motivated” doing. Thereby, it is suggested that the possibility that the character A is selected as the battle character in the battle effect is high.

  On the other hand, the winning character of the teammate character changes as the performance shown in FIG. 35 (e) is executed. As shown in FIG. 35 (f), “50%” is displayed below the character A, and “90%” is displayed below the character B. Thereby, it is suggested that the possibility that the ally character will win increases regardless of which character is selected. Thus, the display which improves the win of a teammate character in FIG.35 (f) can also be said to be an example of a suggestion effect.

  When the fourth game in the precursor period is started, as shown in FIG. 35 (g), a character that is likely to be selected as a battle character is switched. In FIG. 35, this is because a pattern C is set in which the effect is switched from the a system effect to the b system effect in the fourth game, and the game start time is set as the switching timing.

  In FIG. 35 (g), the character B is displayed larger than the character A, the character A speaks a message “tired”, and the character B speaks a message “let's change”. ing. This suggests that it is highly likely that the character B is selected instead of the character A as the battle character in the battle effect. When the switching timing is determined after the first stop, the a system effect is executed until the switching timing is reached, and the b system effect is switched when the switching timing is reached.

  As for the win of the teammate character, “50%” is displayed under the character A and “90%” is displayed under the character B, as in FIG. 35 (f). It is suggested that when the character B is selected rather than the character A, there is a high possibility that the teammate character wins in the battle effect and is notified that the AT has been acquired. Thereby, while suggesting that there is a high possibility of being determined to be a character B having a high win as a battle character in the battle performance, it is possible to have a sense of expectation that the player has won the AT. Note that FIG. 35 (g) is an example of the b system effect.

  At the end of the fifth game in the precursor period, as shown in FIG. 35 (h), an image of an enemy character, a message such as “opposing opponent character B”, and a message “battle start!” Are displayed. Thereby, it can be notified that the battle effect with the character B is started.

  Battle production starts from the next game. In the battle effect, after the AT lottery, the effect that the teammate character defeats the battle character when the AT is acquired is executed, and then a message “Victory!” Is displayed as shown in FIG. The fact that the AT has been acquired is notified. On the other hand, as a result of the AT lottery, when the AT has not been acquired, an effect that the teammate character is defeated by the battle character is executed, and then a message such as “defeat!” Is displayed as shown in FIG. You will be informed that you could not win.

  As described above, by executing the battle related effects, the following effects (i) to (viii) are obtained as main effects.

  (I) According to the slot machine 1 described above, the precursor effect is executed at a higher rate when the AT is won than when the AT is not won, as shown in FIG. For this reason, by executing the precursor effect as illustrated in FIGS. 35A to 35G in the precursor period until the execution of the battle effect that informs whether or not the number of AT games is given, the AT It is possible to suggest in advance the degree of expectation that the number of winning AT games will be awarded.

  Further, as shown in FIG. 30, the pattern of the prelude production is higher in the AT winning ratio than in the AT non-winning state, and from the a system to the b system in which the switching from the a system to the b system is not possible. The patterns B to E to be switched to the system are determined. For this reason, in the precursor period, the degree of expectation can be improved by switching from the a system to the b system.

  Furthermore, as shown in FIG. 33, the execution ratio of the suggestive effect is higher when the patterns B to E are higher than when the pattern A, and when the pattern is determined to have a higher expectation level, There is a high ratio of suggestive effects being executed at an early stage (number of games) in the precursor period. For this reason, depending on whether the suggestion effect was executed in the precursor period and at what timing the suggestion effect was executed, the ratio of the type of the precursor effect to be switched to the b system and the switching timing to the b system are different. Switching to the b system is performed. As a result, the degree of expectation can be made different depending on whether the suggestion effect was executed in the precursor period and at what timing the suggestion effect was executed. As a result, the suggestion effect is executed and the system is switched to the b system depending on whether the suggestion effect is executed and the switching timing is before the system is switched to the b system effect during the precursor period in which the precursor effect is executed. It is possible to change the player's sense of expectation and to increase the interest of the game.

  (Ii) According to the slot machine 1 described above, as shown in FIG. 33, the suggested effect is executed at a higher rate when the established AT lottery condition is second than when the established AT lottery condition is first. The Also, as shown in FIG. 27 and FIG. 28, the number of AT games is given at a higher rate when the second AT condition is satisfied than when the established AT lottery condition is first, and the number of AT games is larger. Number is given. Thereby, even if it is a case where a suggestion effect is performed, an expectation degree can be varied according to the execution timing. As a result, it is possible to change the player's feeling of expectation for switching to the b-system production and the number of AT games depending on the execution timing of the suggestion production. Can be improved.

  (Iii) According to the slot machine 1 described above, as shown in FIG. 33, the suggestion effect is executed according to different distribution ratios depending on whether the established AT lottery condition is the first or the second. And whether or not to set the execution timing. Thereby, a player can be made to pay attention also to the type of established AT lottery conditions.

  (Iv) According to the slot machine 1 described above, as shown in FIGS. 35 (b) and 35 (g), the type of battle effect to be executed afterwards, that is, the battle character is the character A. Or a battle effect with the character B is suggested. Thereby, the expectation with respect to a battle effect can be varied according to the kind of sign effect, and the interest of the game during the sign period can be improved.

  (V) According to the slot machine 1 described above, as shown in FIG. 26, the first AT lottery condition is established by winning a weak cherry or a middle cherry, and the second AT lottery condition is strong. It is established on condition that a cherry is won or BB or RB is won. Further, as shown in FIG. 33, whether or not the suggestion effect is executed according to different distribution ratios and the execution timing is determined depending on whether the established AT lottery condition is the first or the second. Is determined. Thereby, since the suggestion effect is executed according to the type of winning winning, it is possible to make the player pay attention to which winning is won.

  (Vi) According to the slot machine 1 described above, as shown in FIG. 30 and FIG. 31, the higher the degree of expectation, the higher the ratio of switching to the b system at an early stage (number of games) in the precursor period . For this reason, the degree of expectation can be varied depending on the timing at which switching to the b system is executed in the precursor period. As a result, even when the system is switched to the b system during the precursor period in which the precursor effect is executed, the expectation can be changed according to the switching timing, and the interest of the game can be improved. it can.

  (Vii) According to the slot machine 1 described above, as shown in FIG. 32, the system is switched to the b system so that the switching timing with the highest expectation is different according to the pattern of the indication effect. As a result, it is possible to improve the degree of attention to the switching timing to the b system.

  (Viii) According to the slot machine 1 described above, as shown in FIG. 26, the AT lottery is performed according to different distribution ratios depending on whether the established AT lottery condition is the first or the second. . In addition, according to the result of the AT lottery, as shown in FIG. 30, the sign effect pattern is determined depending on whether or not the AT is won. For this reason, depending on whether the established AT lottery condition is the first or second, the sign effect pattern, that is, the switching timing to the b system is determined. As a result, it is possible to make the player pay attention to the type of AT lottery condition that is established.

[Various processes included in the image control process]
The sub-control unit 91 executes the navigation effect execution process included in the image control process, so that, when controlled by the AT, based on the command from the main control unit 41, the game state is set as described above. The corresponding navigation effect is executed when the corresponding navigation target combination is won.

  In addition, the sub-control unit 91 performs a game state effect execution process included in the image control process, so that a game state effect related to the current game state or effect state is displayed on the liquid crystal display 51, effect effect LED 52, and speaker 53. , 54, and an electrical component such as a reel LED 55.

  As the gaming state effect, for example, when the non-AT is being performed regardless of the gaming state, a normal effect (for example, displaying a message such as “Normal” on the liquid crystal display 51) is performed. In addition, a special effect (for example, a message such as “AT in progress” is displayed on the liquid crystal display 51) is performed during the AT regardless of the gaming state. Further, when the game is in the AT, the number of games that have been consumed during the AT is displayed.

  Returning to FIG. 25, after the image control process is completed, the game history control process is executed based on the game history control module (Sp8). The game history control process in the step of Sp8 is a process executed by the sub control unit 91 according to the game history control module. In the game history control process, a game history or the like corresponding to the result of the game or the effect is accumulated, and the accumulated game history is output so that it can be browsed, or externally output using a two-dimensional code or the like.

  FIG. 36 is a flowchart showing the control content of the power interruption process (sub) executed when the sub control unit 91 determines that the power interruption flag is set in the timer interrupt process (sub) described above.

  In the power interruption process (sub), first, the sub control unit 91 reads the backup data of the game history control module from the work RAM (St0-1). Next, predetermined data conversion is performed on the data read from the work RAM to create backup data (St0-2). Then, the sub control unit 91 stores the created backup data in the SRAM 99 (backup RAM) (St0-3). Next, the sub-control unit 91 calculates the exclusive OR of the backup data converted in St0-2, calculates the checksum of the backup data of the game history control module, and sets this in the SRAM 99 (backup RAM) ( St0-4). After setting the checksum data, the sub-control unit 91 sets a backup flag indicating that the backup has been executed in the SRAM 99 (backup RAM) (St0-5).

  Here, the data conversion process in step St0-2 will be described. In St1, the sub-control unit 91 reads 2 bytes (16 bits) of data from the work RAM which is an internal memory. In this embodiment, an SRAM 99 capable of only 8-bit bus access is connected as an external memory and used as a backup RAM. As already described, in this embodiment, the sub-control unit 91 can only perform 16-bit or 32-bit bus access to an external device such as an external memory. Then, even if the 16-bit data read from the work RAM is stored in the SRAM 99 (backup RAM) as it is, only the 8-bit data can be recognized on the SRAM 99 (backup RAM) side, so the upper 8 bits are lost, A situation occurs in which only lower 8-bit data can be stored in the SRAM 99 (backup RAM). Therefore, in the step of Sm2, the 16-bit data read in St0-1 is converted into two data by performing the following data conversion process.

  First, for the first conversion data, the 16-bit data read in St0-1 is masked with the mask value “00FF (H)” as it is, and only the lower 8 bits of the original data read in St0-1 are stored. The data set in the lower 8 bits is generated as it is. For the second conversion data, the 16-bit data read in St0-1 is shifted by 8 bits (therefore, the value in the upper 8 bits of the original data is moved to the lower 8 bits). The data after the shift processing is masked with the mask value “00FF (H)”, and data in which the upper 8 bits of the original data read in St0-1 are set to the lower 8 bits is generated. Then, by storing these two pieces of conversion data in the SRAM 99 (backup RAM) in the step St0-3, the upper and lower values of the original data read in St0-1 are divided into two data. The power can be backed up without missing.

  In the steps St2, St7, and St12, which will be described later, the same data conversion processing as that in the steps St0-2 described above is executed.

  Next, the sub-control unit 91 reads the backup data of the sound / LED control module from the work RAM (St1). Next, predetermined data conversion is performed on the data read from the work RAM to create backup data (St2). Then, the sub control unit 91 stores the created backup data in the SRAM 99 (backup RAM) (St3). Next, the sub-control unit 91 calculates the exclusive OR of the backup data converted in St2, calculates the checksum of the backup data of the sound / LED control module, and sets it in the SRAM 99 (backup RAM) (St4). ). After setting the checksum data, the sub-control unit 91 sets a backup flag indicating that the backup has been executed in the SRAM 99 (backup RAM) (St5).

  Next, the sub control unit 91 reads backup data of the AT control module from the work RAM (St6). Next, predetermined data conversion is performed on the data read from the work RAM to create backup data (St7). Then, the sub control unit 91 stores the created backup data in the SRAM 99 (backup RAM) (St8). Next, the sub-control unit 91 calculates the exclusive OR of the backup data converted in St7, calculates the checksum of the backup data of the AT control module, and sets this in the SRAM 99 (backup RAM) (St9). After the checksum data is set, the sub-control unit 91 sets a backup flag indicating that the backup has been executed in the SRAM 99 (backup RAM) (St10).

  Next, the sub control unit 91 reads the backup data of the image control module from the work RAM (St11). Next, predetermined data conversion is performed on the data read from the work RAM to create backup data (St12). Then, the sub control unit 91 stores the created backup data in the SRAM 99 (backup RAM) (St13). Next, the sub-control unit 91 calculates the exclusive OR of the backup data converted in St12, calculates the checksum of the data used in the reel rotation control module, and sets this in the SRAM 99 (backup RAM). (St14). After setting the checksum data, the sub-control unit 91 sets a backup flag indicating that the backup has been executed in the SRAM 99 (backup RAM) (St15).

  After setting the backup flag at St15, access to the RAM 91c is prohibited (St16), and the setting of the general-purpose port corresponding to the general-purpose terminal to which the CS signal line connected to the SRAM 99 is connected is set to the input port. (St17), the output function of the chip select signal to the SRAM 99 is forcibly disabled. Thereafter, the voltage decreases, the CPU 91a of the sub-control unit 91 stops and shifts to a standby state. And if a voltage falls in this standby state, it will be in an operation stop state internally. Therefore, the sub-control unit 91 reliably stops operation when power is interrupted.

  Here, a specific example when the backup data of each program module is stored in the SRAM 99 (backup RAM) will be described with reference to FIG.

  As described with reference to FIG. 36, among the four program modules of the game history control module, the sound / LED control module, the AT control module, and the image control module, first, the backup data of the game history control module is stored in the SRAM 99 (backup RAM). Store (St0-3). In the SRAM 99 (backup RAM), the start address specified when storing the backup data of the game history control module is set to “A5000”. Therefore, the sub-control unit 91 specifies “A5000” as the start address in step St0-3 and stores the backup data of the game history control module. Then, the process of St0-1 to St0-3 is repeated while incrementing the storage destination address of the SRAM 99 (backup RAM) until backup of all data for the game history control module stored in the work RAM is completed. Run.

  Next, after the backup data of the game history control module is stored, the backup data of the sound / LED control module is stored in the SRAM 99 (backup RAM) (St3). In the SRAM 99 (backup RAM), the start address designated when storing the backup data of the sound / LED control module is set to “A6000”. Therefore, in step St3, the sub-control unit 91 designates “A6000” as the start address and stores the sound / LED control module backup data. Then, the St1 to St3 processes are repeatedly executed while incrementing the storage destination address of the SRAM 99 (backup RAM) until backup of all data for the sound / LED control module stored in the work RAM is completed.

  Next, after the backup data of the sound / LED control module is stored, the backup data of the AT control module is stored in the SRAM 99 (backup RAM) (St8). In the SRAM 99 (backup RAM), the start address designated when storing data used in the AT control module is set to “A7000”. Therefore, the sub-control unit 91 specifies “A7000” as the start address and stores the backup data of the AT control module in step St8. Then, until the backup of all data for the AT control module stored in the work RAM is completed, the processing of St6 to St8 is repeatedly executed while incrementing the storage destination address of the SRAM 99 (backup RAM).

  Next, after the backup data of the AT control module is stored, the backup data of the image control module is stored in the SRAM 99 (backup RAM) (St13). In the SRAM 99 (backup RAM), the start address designated when storing the backup data of the image control module is set to “A8000”. Therefore, the sub-control unit 91 specifies “A8000” as the start address in step St13, and stores the backup data of the image control module. Then, until backup of all data for the image control module stored in the work RAM is completed, the processing of St11 to St13 is repeatedly executed while incrementing the storage destination address of the SRAM 99 (backup RAM).

  As described above, since backup data is stored for each program module, when only one of the program modules needs to be changed in another model, only that program module needs to be replaced, and the change of the presentation control program is facilitated. . Since the start address for storing the backup data of each program module is set for each program module, it is not necessary to maintain consistency for storing the backup data even if the model is changed. The backup data may be stored at the start address set in. For this reason, it is possible to simplify the program at the time of storing the backup data, and it is possible to reduce the man-hour for developing the program. Similarly, checksum data is also created for each program module, so even if the model is changed, there is no need to maintain consistency for storing checksum data, and the program for storing checksum data is simplified. Can reduce the man-hours for program development.

  In addition, a game history control module indirectly related to a player's profit, such as when it is possible to receive various benefits by, for example, storing game history on an external server etc. Since the data is stored in the SRAM 99 (backup RAM) in preference to other backup data, the backup data of the game history control module can be secured quickly, and it is effective in preventing loss of the player's profit. Is.

  Further, since the backup data of the AT control module related to the player's profit is stored in the SRAM 99 (backup RAM) in preference to the image control module, the backup data of the AT control module can be secured quickly, and the player's profit. It is effective in preventing the occurrence of loss.

  Next, in FIGS. 38 to 40, in the power interruption processing (main) Sm2, Sm7, Sm12, Sm17 in FIG. 14 and in the power interruption processing (sub) St0-2, St2, St7, St12 in FIG. The data conversion to be executed will be specifically described.

  FIG. 38 is an explanatory diagram showing the contents of data in the backup RAM when data is transferred between the work RAM and the backup RAM with (A) the same bus width (B) and different bus widths. In the present embodiment, data is expanded in the work RAM for processing, and the data expanded in the work RAM is stored in the backup RAM as backup data. “(H)” indicates a hexadecimal number.

  The work RAM stores 16 pieces of 8-bit (1 byte) data at each address. For example, data “00”, “01”... “0F” are stored in addresses “0000h” to “000Fh”, respectively, and data “10” and “001Fh” are stored in addresses “0010h” to “001Fh”. 11 ”...“ 1F ”data is stored.

  As shown in Fig. 38 (A), a 8-bit bus accessible microprocessor can be used for external devices such as external memory, and the external RAM backup RAM can be accessed with a bus width of 8 bits (1 byte). In this case, that is, when the accessible bus widths coincide with each other, when the backup data is transferred from the work RAM to the backup RAM, the 8-bit backup data is stored as it is. Does not happen. Specifically, for example, when the data stored in the work RAM at the address “0000h” is read in 8-bit units and the 8-bit backup data “00” is transferred to the backup RAM, the transferred backup data “00” is transferred. Is stored in “0000h” of the backup RAM. Similarly, when the 8-bit backup data “01” stored at the address “0001h” in the work RAM is transferred to the backup RAM, the transferred backup data “01” is stored in the backup RAM. Similarly, backup data stored at other addresses is also stored at corresponding addresses.

  On the other hand, as shown in FIG. 38 (B), as shown in this embodiment, a microprocessor capable of only 32-bit or 16-bit bus access to an external device such as an external memory is used. When the backup RAM can be accessed with a bus width of 8 bits (1 byte), that is, when the accessible bus widths do not match, data is read from the work RAM in units of 16 bits, and the backup RAM When the data is transferred to the data, the upper 8 bits of data transferred from the work RAM are lost, and the entire 16 bits cannot be transferred. Specifically, for example, when 16-bit backup data “0001” stored at addresses “0000h” and “0001h” in the work RAM is transferred to the backup RAM, the upper 8-bit data “01” is lost. Only the lower 8 bits of data “00” are stored in “0000h” of the backup RAM. Similarly, when the 16-bit backup data “0203” stored in the addresses “0002h” and “0003h” in the work RAM is transferred to the backup RAM, the upper 8-bit data “03” is lost and the lower 8-bit data is lost. Only data “02” is stored in “0002h” of the backup RAM. That is, the upper 8 bits of the 16-bit backup data are lost, and the backup data is stored only at even addresses in the backup RAM.

  Therefore, in order to prevent data loss even when the bus widths of the data buses of the work RAM and the backup RAM do not match, in the present invention, the power interruption processing (main) Sm2, Sm7, Data conversion is performed in Sm12, Sm17, and St0-2, St2, St7, and St12 of the power interruption process (sub) in FIG.

  First, the case where the bus width to be accessed on the microprocessor side does not match the bus width accessible on the backup RAM side and data in the upper 1 byte is lost will be described with reference to FIG. For example, data is stored from the work RAM to the backup RAM in Sm3, Sm8, Sm13, Sm18 in the power interruption process (main) in FIG. 14 and St0-3, St3, St8, St13 in the power interruption process (sub) in FIG. In this case, it is assumed that 16-bit backup data “1234” is transferred to the backup RAM. In this case, as described with reference to FIG. 38, the upper 8-bit data “34” is missing and stored. Therefore, when the restoration process is performed in Sa24 of FIG. 10 or Sn19 of FIG. 24, when the backup data is read from the backup RAM, the upper 8-bit data “34” is lost, and only the lower-order 1-byte data “12” is stored. Stored in work RAM. However, this cannot return to the state before the power interruption.

  Therefore, as shown in FIG. 39B, in this embodiment, when data is transferred from the work RAM to the backup RAM, the power interruption processing (main) Sm2, Sm7, Sm12, Sm17 and FIG. Data conversion is performed in St0-2, St2, St7, and St12 of the power interruption process (sub) in FIG.

  Specifically, for example, “1234 (H)” that is 16-bit data is converted into two data. For the first data, the data “1234 (H)” read from the work RAM is masked with the mask value “00FF (H)” as it is, and converted to “0034 (H)”. For the second data, the data read from the work RAM is shifted by 8 bits, masked with the mask value “00FF (H)”, and converted to “0012 (H)”. As a result, when 16-bit backup data “1234 (H)” is read from the work RAM and data conversion is performed, it is composed of two 16-bit data consisting of “0012 (H)” and “0034 (H)”. A total of 32 bits (4 bytes) of backup data is created. When each of the two 16-bit backup data is sequentially written in the backup RAM, as described above, the upper 8 bits of data “00” are lost, so the lower 8 of the one backup data “0012”. Bit data “12” is stored in the backup RAM. Similarly, “34”, which is lower byte data of the other backup data “0034”, is stored in the backup RAM. As a result, even when 16-bit backup data “1234” is transferred using a data bus having an 8-bit bus width, the data can be stored in the backup RAM without being lost.

  Also, the reverse data conversion process is performed when the return process is performed in Sa24 of FIG. 10 or Sn19 of FIG. Specifically, since only 8-bit data can be read from the backup RAM, the data “12 (H)” and the data “34 (H)” are sequentially read out and combined to form the data “1234 ( H) "is restored, and the restored data is stored in the work RAM.

  Next, referring to FIG. 40, data conversion is performed in Sm2, Sm7, Sm12, Sm17 in the power interruption process (main) in FIG. 14 and St0-2, St2, St7, St12 in the power interruption process (sub) in FIG. A data storage state in the backup RAM when the data is stored from the work RAM to the backup RAM will be described.

  As described above, for example, the 16-bit backup data “0001” stored in the addresses “0000h” and “0001h” in the work RAM is converted, and “0000” which is a total of 32-bit backup data. And “0001” are created. When this is transferred to the backup RAM, the upper 8-bit data “00” added at the time of conversion is lost, and only the lower 8-bit data “00” and “01” are stored in the backup RAM. If the upper 8 bits of data (data “00” added at the time of data conversion) is lost, no data is stored in the odd addresses “+ 0001h” and “+ 0003h”, so the lower 8 bits of the transferred 16-bit data “0000” The bit data “00” is stored in the even address “+ 0000h”, and the data “01” of the lower 8 bits of the 16-bit data “0001” transferred subsequently is stored in the even address “+ 0002h”. As described above, when data conversion is performed on other data and the data is transferred, the data is similarly stored at even addresses in the backup RAM.

  In the present embodiment, the main control unit 41 is connected to an SRAM 50 as an external memory, and this SRAM 50 is used as a backup RAM. Similarly, the sub-control unit 91 is connected to an SRAM 99 as an external memory, and this SRAM 99 is used as a backup RAM. As described above, when the external memory is used as the backup RAM instead of the built-in memory of the main control unit 41 or the sub control unit 91, the CPU side stores the RAM when the supply voltage is unstable like a power failure. Even if access to the memory is prohibited, a phenomenon may occur in which a chip select signal for designating a RAM or a WR signal indicating the timing of writing to the RAM is output. If these signals coincide by chance, There was a problem that data in the external memory was rewritten.

  On the other hand, in the present embodiment, the voltage at which the main CPU 41a of the main control unit 41 and the sub CPU 91a of the sub control unit 91 stop when the power is interrupted (the voltage at which the reset signal for the main CPU 41a is output or the reset signal for the sub CPU 91a Output voltage) is a voltage at which the I / O port 41d where the input / output control of the signal from the main control unit 41 is performed and the I / O port 91d where the input / output control of the signal from the sub control unit 91 is stopped are stopped. It is set lower than (the voltage at which the reset signal for the I / O port 41d is output and the voltage at which the reset signal for the I / O port 91d is output), and the main CPU 41a of the main control unit 41 and the sub control unit 91 The I / O port 41d and the I / O port 91d stop operating before the sub CPU 91a. As a hardware configuration, the I / O port 41d and the I / O port 91d are not operated after the operation of the main CPU 41a and the sub CPU 91a is stopped, so that the chip select signal for designating the SRAM and the timing of writing to the SRAM can be set. The phenomenon that the WR signal shown is output is prevented, and the data in the external memory is prevented from being rewritten.

  Specifically, the main control unit 41 and the like will be described as an example. As shown in FIG. 41, +5 V (1) for driving the main CPU 41a, the SRAM 50, etc. It is configured to receive the supply of two power sources including + 5V (2) for driving the port 41d.

  Among these, the power line of + 5V (1) is connected to VDD (CPU) (terminal for power input for driving the main CPU 41a) of the main control unit 41 and branches in the middle to monitor the voltage of the reset circuit 49. Also connected to the terminal IN1.

  On the other hand, the power line of + 5V (2) is connected to (VDD (I / O) (power input terminal for driving the I / O port 41d) of the main control unit 41, and is branched in the middle and reset. It is also connected to the voltage monitoring terminal IN2 of the circuit 49.

  In other words, the reset circuit 49 can individually monitor the voltage of the power supply line that drives the main CPU 41a and the voltage of the power supply line that drives the I / O port 41d.

  Further, the reset signal output terminal OUT1 of the reset circuit 49 is connected to the reset input terminal RST (CPU) to which a reset signal for the main CPU 41a of the main control unit 41 is input, and the reset signal output terminal OUT2 and the main control unit 41 are connected. A configuration that is connected to a reset input terminal RST (I / O) to which a reset signal for the I / O port 41d is input, and that can individually output a reset signal for the main CPU 41a and a reset signal for the I / O port 41d. It has become.

  The reset circuit 49 outputs a reset signal to the main CPU 41a when detecting that the voltage of the power supply line that drives the main CPU 41a has dropped to + 1.2V, while the power supply that drives the I / O port 41d. When it is detected that the voltage of the line has dropped to +3.3 V, which is set higher than the voltage for outputting the reset signal for the main CPU 41a, the reset signal for the I / O port 41d is output.

  As a result, the I / O port 41d stops operating before the main CPU 41a of the main control unit 41. By preventing the I / O port 41d from operating after the main CPU 41a stops operating, The phenomenon that the chip select signal designating the SRAM or the WR signal indicating the timing of writing to the SRAM is prevented from occurring, and the data in the external memory is prevented from being rewritten. .

  Also, the sub-control unit 91 and the reset circuit 95 have the same configuration as that shown in FIG. 41, and the I / O port 91d stops operating before the sub-CPU 91a of the sub-control unit 91. In other words, after the operation of the sub CPU 91a is stopped, the I / O port 91d is disabled so that a chip select signal designating the SRAM or a WR signal indicating the timing of writing to the SRAM is output. This prevents occurrence of data and prevents data in the external memory from being rewritten.

  In addition to the SRAM 50 and the SRAM 99, the driving voltage of the main CPU 41a and the sub CPU 91a is also used for other devices (such as an LED driving circuit and a liquid crystal driving circuit) mounted on the same substrate. The speed at which the voltage drops when power is interrupted may not be stable depending on the power usage status of the device. As described above, the I / O port is preceded by the main CPU 41a of the main control unit 41 and the sub CPU 91a of the sub control unit 91 as described above. Even if the hardware configuration in which the operation of the 41d and the I / O port 91d is stopped first is employed, the operation of the main CPU 41a and the sub CPU 91a is performed before the operation of the I / O port 41d and the I / O port 91d is stopped. In such a case, it has been confirmed that the chip is stopped. The remaining potential WR signal indicating a timing from being output, there is a possibility that data in the external memory will be rewritten.

  Therefore, in this embodiment, after the backup data is stored in the backup RAM in the event of a power failure, the general-purpose port setting corresponding to the general-purpose terminal connected to the CS signal line connected to the backup RAM is set to the input port. Therefore, the chip select signal output function for the backup RAM is forcibly disabled, and the writing of data to the backup RAM is also disabled for software, and the voltage is unstable as during a power failure. Thus, it is possible to more reliably prevent the data in the backup RAM from being rewritten.

  In this embodiment, the configuration in which the backup RAM is mounted on the same substrate as the main control unit 41 or the sub control unit 91 is described. However, the substrate is separate from the main control unit 91 or the sub control unit 91. Even in the configuration where the backup RAM is executed above, by forcibly disabling the function of outputting the chip select signal to the backup RAM as described above, in the unstable voltage state at the time of power failure Thus, it is possible to reliably prevent the data in the backup RAM from being rewritten.

  In this embodiment, the backup RAM is provided separately in both the main control unit 41 and the sub control unit 91, but only one of the main control unit 41 or the sub control unit 91 is provided with a backup RAM. If the microcomputer and at least the microcomputer backup are stored in the external memory, the output function of the chip select signal to the external memory for backup is forcibly disabled. Thus, the same effect as described above can be obtained.

  In the present embodiment, after the main control unit 41 and the sub control unit 91 are activated, after the setting of the built-in device and other built-in registers, before determining whether the backup data is normal, By setting the general-purpose port setting corresponding to the general-purpose terminal to which the CS signal line connected to the SRAM 50 or SRAM 99 is connected to the output port, the output of the chip select signal of the SRAM 50 or SRAM 99 is enabled. Since the function of outputting a chip select signal to the SRAM 50 or SRAM 99 is disabled until it is determined whether or not it can be restored based on the backup data stored in the SRAM 50 or SRAM 99, power supply is started. This prevents the SRAM 50 and SRAM 99 data from being rewritten in an unstable state after the operation. It can be.

  While the embodiments of the present invention have been described with reference to the drawings, the present invention is not limited to these embodiments, and various modifications and applications are possible. Hereinafter, modifications of the above-described embodiment that can be applied to the present invention will be described.

[When the AT lottery conditions are met during the warning or battle]
In the above-described embodiment, when the AT lottery condition is established and the sign effect or the battle effect is executed, the AT lottery is performed by winning a specific winning combination (see FIG. 26) that establishes the AT lottery condition again. The number of AT games can be given or added according to the result of the AT lottery. In such a case, the following processing may be performed.

  First, if the warning effect or battle effect that has already been executed is an effect set based on the AT winning, that is, if the number of AT games has already been assigned, Reproductions after the relevant selection timing may be rewritten and executed with a higher expectation (no change in the number of games in which the effects are executed), or the pre-announced effects and battle effects that have already been executed. May be executed continuously after the timing.

  On the other hand, in the case where the warning effect or battle effect that has already been executed is not an effect set based on the AT winning, that is, when the number of AT games has not yet been given, About the battle effect, the effect after the winning timing is rewritten to an effect with a higher expectation and executed (the number of games in which the effect is executed is not changed). As a result, it is possible to execute the warning effect and the battle effect according to whether or not the number of AT games is given without extending the period in which the warning effect and the battle effect already being executed are executed. Compared with the case where such rewriting is not performed, the reliability of the warning effect and the battle effect can be improved.

[Conditions for battle-related effects]
In the above-described embodiment, an example is described in which battle-related effects such as a sign effect, an suggestion effect, and a battle effect are executed when winning is performed according to the lottery result by the battle-related effect lottery process shown in FIG. However, the battle-related effect may be executed in the battle-related effect lottery process and the effect switch 56 may be operated. For example, in the indication effect, the switch from the a system effect to the b system effect, the execution of the suggestion effect, etc., respectively, after winning in the lottery, further to the effect switch 56 when the execution timing is reached. It is possible to perform an effect that promotes the above operation and execute it only when the effect switch 56 is operated, and when it is not operated, it may not be executed even if it is won by lottery. Thereby, since a battle related effect is performed by operation of a player, the intervention degree to a game can be improved.

[Regarding lottery order of sign and suggestion]
In the above-described embodiment, after performing the lottery regarding the precursor effect corresponding to the specific effect, in consideration of the lottery result, as shown in FIG. An example in which a lottery is performed so that a suggestion effect corresponding to a special effect is executed at a higher rate than when the pattern A is other than the pattern A is described. However, for the lottery order of the sign effect and the suggestion effect, first, after performing the lottery regarding the suggestion effect, for example, when it is determined to execute the suggestion effect, the suggestion effect is not executed. A lottery may be performed so as to be determined as one of the patterns B to E as a precursor effect at a higher rate than when determined. In this case, for the lottery regarding the suggestion effect, for example, the lottery may be determined so that the suggestion effect is executed at a higher rate when the AT is won than when the AT is not won. .

[Regarding lottery order of sign production and notification production]
In the above-described embodiment, after performing the lottery regarding the precursor effect corresponding to the specific effect, the lottery result is taken into consideration, as shown in FIG. An example in which a lottery is performed so that a battle effect corresponding to a notification effect is executed has been described. However, the lottery order of the warning effect and the battle effect is determined by taking a lottery regarding the battle effect first, and then considering the lottery result, for example, when A is determined as the battle character, a high ratio as the warning effect. When the pattern A is determined and B is determined as the battle character, a lottery may be performed so as to be determined as one of the patterns B to F other than the pattern A at a high rate as a precursor. In this case, for the lottery regarding the battle effect, for example, a lottery may be performed such that B is determined as the battle character at a higher rate when the AT is won than when the AT is not won. .

[About the lottery method of the prelude and suggestion]
In the above-described embodiment, as illustrated in S02 and S06 in FIG. 29, the example in which the lottery regarding the sign effect and the lottery regarding the suggestion effect are performed separately has been described. In other words, the example in which the sign effect and the suggestion effect are drawn separately has been described. However, the lottery method of the sign effect and the suggestion effect is not limited to the individual lottery, but whether or not the sign effect is performed and whether or not the suggestion effect is performed in one lottery. Further, the execution timing may be determined (one-shot determination). For example, for each of the precursor effect patterns A to E, a plurality of types of patterns including a pattern that does not execute the suggestive effect and a pattern that has a different execution timing of the suggestive effect (for example, if the pattern A is the pattern A1 without the suggestive effect execution, A pattern A2 for executing the suggestion effect in the first game, a pattern A3 for executing the suggestion effect in the second game, and the patterns A to E including a plurality of types of patterns, a pattern F, and a pattern having no sign effect. One of the patterns may be determined. In this case, when AT is won, it is a pattern with a precursor effect at a higher rate than when AT is not won, and patterns B to F are faster than pattern A, and the pattern has an earlier switching timing. Thus, it may be determined to be a pattern in which the suggestion effect is executed, and the execution timing is an early stage pattern.

[Relationship between benefits and battle-related effects]
In the above-described embodiment, after determining whether or not a privilege is given, an example of determining a battle-related effect so as to match the determination result based on the determination result, that is, a privilege predetermination as a lottery pattern Although the example which employ | adopted the pattern was demonstrated, a lottery pattern is not restricted to this, For example, after determining a battle related effect, according to the result of the determined effect (result of a battle effect), whether a privilege is provided or not. In other words, a post-privilege decision pattern may be adopted. For example, a privilege may be given if a task selected from a plurality of tasks (missions) is achieved.

[About the period during which the prelude and battle effects can be executed]
In the above-described embodiment, a precursor period for five games is determined in advance as a period in which a precursor effect can be executed, and a period in which five battles are executed as a period in which a battle effect as a notification effect can be executed in advance. The example that has been defined has been described. However, the precursor period and the execution period of the battle effect are not limited to predetermined ones, and may be determined randomly using random numbers or the like. For example, the precursor period may change according to the type of pattern determined to be executed. Moreover, the execution period of a battle effect may change according to the kind of battle character in the said battle effect.

[About specific effects]
In the above-described embodiment, as shown in FIGS. 35A to 35H, the mode of the precursor effect corresponding to the specific effect can be a battle character in the battle effect from the size of the enemy character and the content of the remarks. This suggests the possibility of the teammate character winning in the battle direction when the player wins the battle character based on the winning number of the teammate. An example that indirectly suggests the possibility and expectation to do is explained. However, the specific effect suggests the degree of expectation that the privilege will be given by the subsequent notification effect, and it suggests in any manner as long as it can suggest different expectations depending on the type. There may be. For example, a specific effect may be executed by displaying a specific background image on the liquid crystal display 51.

  Moreover, in the Example mentioned above, as an effect | action performed as a specific effect, the effect of system a and the effect of system b were illustrated, but not only two types but three or more types are provided. Also good. For example, the production of the c system, which has a higher expectation than any of the a and b systems, is provided. As a specific production pattern, a pattern a (such as patterns A to E in the embodiment) that can be switched from the a system to the b system, A pattern b that can be switched from the a system to the c system, a pattern c that can be switched from the b system to the c system, and a plurality of types of patterns with different switching timings may be provided for each of the patterns a to c. In this case, for example, when the specific effect of the pattern b is being executed, the expectation is higher when the system is switched from the a system to the c system at an earlier stage. When the specific effect is being executed, the degree of expectation may be higher when the system is switched from the b system to the c system at a later stage. In other words, the switching may be performed so that the timing at which the degree of expectation increases according to the type of specific effect.

[About special effects]
In the above-described embodiment, as shown in FIG. 35 (e), the suggestion effect corresponding to the special effect is displayed in a special manner to indicate that the friend character has been powered up. An example was described. However, the special effect may be suggested in any manner as long as it allows the player to recognize that the ratio of switching to the b system in the precursor effect is high when executed. . For example, the special effect may be executed by flashing the background image displayed on the liquid crystal display 51.

  Further, a plurality of types of special effects may be provided. In this case, even if the ratio of high expectation level switching is different depending on the type of specific effects to be executed. Good. Moreover, the special effect which suggests that the ratio by which high expectation degree switching is performed in the said specific effect becomes high according to the kind of specific effect performed may differ. For example, with respect to the pattern A of the indication effect, the ratio of the high expectation level switching is higher when the indication effect A is executed than the indication effect B. The ratio at which the high expectation level switching is performed may be higher when the suggestion effect B is executed. Thereby, when the suggestion effect is executed, the degree of expectation can be varied depending on the type of the suggested effect that is executed in relation to the type of the specific effect being executed.

[About the form of notification effect]
In the above-described embodiment, as shown in FIG. 35 (i) or (h), the battle effect corresponding to the notification effect is played between the enemy character and the friend character, and the friend character is An example has been described in which the player is made aware that a privilege has been granted by winning. However, the notification effect may be any mode as long as it is a mode for reporting whether or not a privilege has been granted. For example, the player may recognize that a treasure hunt game has been started and that a privilege has been granted by digging for a treasure.

[About benefits]
In the embodiment described above, whether or not the number of AT games has been acquired, that is, controlled by the AT, has been described as an example of a privilege, but the bonus may be a winning of a big bonus or a regular bonus. In this case, for example, after winning the bonus by the internal lottery, or after shifting to the prelude period that can be won simultaneously with the bonus, the presence or absence of the bonus winning will be notified according to the result of the battle performance. It may be.

  Furthermore, in the above-described embodiment, as a privilege, the ratio of the game value given to the player to the game value (the number of bet medals and the game ball that has been struck) used to play the game ( The value that directly affects the payout rate of medals or game balls) was illustrated. However, the privilege is not limited to this, and may be a value that is beneficial to the player in the progress of the game. For example, information that informs whether or not it is in the so-called AT latency that has been acquired non-AT but has already acquired the number of AT games and has been determined to be controlled by AT, or notification When this is done, information that is executed so as to actually become an AT latent state with a predetermined reliability (that is, latent suggestion information that suggests an AT latent state) may be notified.

  In addition, as a privilege, execution of privilege production (special character appearance, etc.), execution of set value suggestion production to suggest a set value that has been set, in a game shop where gaming machines are installed by collecting a certain number Points may be exchanged for a defined service, a QR code (registered trademark) that can download bonus video and bonus information on a predetermined website may be displayed.

[Control to AT]
In the embodiment described above, an example in which the AT is controlled according to the number of assigned AT games has been described. However, the control to the AT is not limited to this. For example, the number of times that the navigation effect can be executed is determined, and the AT is executed until the navigation effect is executed by the determined number of times that the navigation effect can be executed. You may make it control. In this case, the number of times that the navigation effect can be performed may be used as a privilege.

  Further, for example, the upper limit grant amount may be determined, and the AT may be controlled until the assigned game value (medal payout number) reaches the determined upper limit grant amount. In this case, the upper limit grant amount may be a privilege.

  Further, the AT is controlled until a predetermined AT end condition is satisfied after a predetermined AT start condition is satisfied, and when the AT end condition is satisfied, a continuous lottery for determining whether or not to continue the AT is performed. Also good. In this case, it is good also considering the continuation probability determined to continue in a continuous lottery as a privilege.

[Regarding the condition that it is not AT]
In the above-described embodiment, an example in which the navigation effect is not executed without being controlled by the AT when the AT flag indicating that the AT is not won is set has been described. However, the navigation effect may be executed with a predetermined probability even when the AT flag indicating that the AT is not won is set.

[Other variations]
(1) In the above-described embodiment, the AT flag indicating that the AT has been won (the AT is being in effect) is not cleared even when the bonus is won, and is maintained thereafter, and again the normal gaming state If the AT can be controlled when the control is controlled, the AT game is updated to the AT flag corresponding to the added number, and the AT game based on the updated AT flag after the bonus ends The example performed according to the number has been described. However, the AT flag indicating that the AT is won may be cleared when the bonus is won. In addition, it may be determined whether to perform additional processing or clear processing for each bonus winning and perform the determined processing. Thereby, the variation when the bonus is won in the state where the AT flag indicating that the AT has been won is set increases, and the interest of the game can be improved.

  (2) In the above embodiment, the variable display device having the three reels 2L, 2C, and 2R is provided, and when all the reels are stopped, one game is finished, and the combination of the display results derived to the three reels. The slot machine where a prize is generated according to the above is explained. That is, a variable display device capable of deriving a display result in each of a plurality of variable display areas capable of variably displaying a plurality of types of identification information each identifiable, and using one game value for one game By setting a predetermined number of bets, the game can be started, and when the display result is derived in all of the plurality of variable display areas, one game is completed, and the plurality of results are obtained as a result of one game. A slot machine in which a winning can be generated according to the combination of the display results derived in each of the variable display areas has been described. However, when a display result is derived to a variable display device capable of variably displaying a plurality of types of identification information that can be identified, one game is completed, and a prize is awarded according to the display result derived to the variable display device. As long as the slot machine can be generated, the slot machine is not limited to one having a variable display device having three reels, but has a single reel or a variable display device having a plurality of reels other than three. It may be.

  In addition, the slot machine to which medals are applied as an example of a game medium used for setting a bet number or giving a game value accompanying winning a prize has been described. However, the slot machine embodying the present invention is used in a pachinko gaming machine. It may be a slot machine (so-called parrot) in which existing game balls are applied as game media. When a game ball is used as a game medium, for example, one medal can correspond to five game balls, and when 3 is set as the number of bets in the first embodiment, 15 This is equivalent to setting the number of bets using game balls.

  In the above embodiment, the slot machine for setting bets using medals and credits is used. However, the present invention is not limited to this, and slots for setting bets using game balls are used. It may be a machine or a fully credit type slot machine that uses only credits to set the bet amount.

  Further, in addition to the medal insertion mechanism such as the flow path switching solenoid 30 and the insertion medal sensor 31, a ball take-in device that takes in game balls, and a take-in ball that detects game balls taken in by the ball take-in device In addition to a medal payout mechanism, such as a hopper motor 34b and a payout sensor 34c, a ball payout device for paying out game balls, a payout ball detection switch for detecting game balls payed out by the ball payout device It is possible to set the number of bets using both medals and game balls and play a game, and the present invention may be applied to a slot machine in which medals and game balls are paid out when a winning occurs.

  (3) In the power supply stop process, the effect control process control module, the fourth symbol process control module, and the process in the power interruption process (sub) of FIG. 36 (for example, St0-1 to St0-5) For the above, the data of any program module is read from the work RAM, the read data is converted to create backup data, and the backup data is stored in the backup RAM. Also, the checksum is calculated, set in the backup RAM, and the backup flag is set. These backup processes are repeated for each module. Note that the order in which the backup processing is performed may be arbitrarily set.

  Moreover, in the process at the time of a power failure return, similarly to the process (for example, Sn6-1 to Sn6-4) in the startup process (sub) of FIGS. 23 to 24, the effect control process control module and the fourth symbol process control are performed. It is determined whether or not the backup flag is set for the module. If the backup flag is set, the backup flag is cleared and the checksum is calculated. These processes are repeated for each module. If the checksums match for all program modules, the program modules are restored before power interruption. If the checksums match for all program modules, initialization processing is performed.

  As described above, in this embodiment, when the power supply is stopped, the backup processing for storing the backup data in the backup RAM is performed for each program module based on the data used in the program module (Sm3, Sm8, Sm13, Sm18, St0-3, St3, St8, St13 in FIG. 36), and a start address is set so as to be stored in a different storage area for each program module, and the memory corresponding to the set start address The backup data from the area is stored in the backup RAM (in Sm3, Sm8, Sm13, and Sm18 in FIG. 14, the backup data is stored at the start address shown in FIG. 15 and in St0-3, St3, St8, and St13 in FIG. 36). To 37 Part to store the backup data to be start address). Therefore, it is possible to complete the backup process for each function of the gaming machine, and it is possible to develop a program related to the backup process for each function, thus facilitating the program development and simplifying the program. As a result, the development man-hours for the program can be reduced. In addition, the backup process can be simplified. In addition, when performing backup processing with a program structure composed of a plurality of program modules, it becomes possible to perform backup processing for each program module in a common way without taking consistency for each model. Development man-hours can be reduced.

  In the above embodiment, each of the game control program and the effect control program has a program module structure. However, the present invention is not limited to this embodiment, and a game machine or a game control program in which only one of the programs is configured by a program module, A slot machine in which a program other than the production control program is configured by a program module, a gaming machine in which at least one of the game control program and the production control program and a program other than the game control program and the production control program are configured by a program module. You may apply the structure shown in said Example.

  In the above embodiment, the game control program is composed of four program modules: an internal lottery control module, an input / output control module, a reel rotation control module, and a payout control module. However, the present invention is not limited to this embodiment. A gaming machine having a game control program in a module structure with at least one program module of the above, or a gaming machine having a game control program in a module structure with a program module other than at least one of the four and the four program modules The configuration shown in the above embodiment may be applied.

  In the above embodiment, the effect control program is composed of four program modules: a game history control module, a sound / LED control module, an AT control module, and an image control module. However, the present invention is not limited to this embodiment. A gaming machine having a presentation control program in a module structure with at least one program module of the above, or a gaming machine having a presentation control program in a module structure with a program module other than at least one of the four and the four program modules The configuration shown in the above embodiment may be applied.

  In the above embodiment, in the power interruption process (main), the backup process is performed in the order of the internal lottery control module, the input / output control module, the reel rotation control module, and the payout control module. However, the backup process is not limited to this example. The configuration shown in the above embodiment may be applied to a gaming machine having a processing order different from that in the above embodiment.

  In the above embodiment, in the power interruption process (sub), the backup process is performed in the order of the game history control module, the sound / LED control module, the AT control module, and the image control module. However, the backup process is not limited to this example. The configuration shown in the above embodiment may be applied to a gaming machine having a processing order different from that in the above embodiment. As a modified example related to the order of backup processing, for example, a gaming machine that performs backup processing of a program module (AT control module in this embodiment) for performing processing related to game control with priority over backup processing of other program modules The configuration shown in the above embodiment may be applied. Specifically, in the above embodiment, in the power interruption process (sub), the backup process is performed in the order of the game history control module, the sound / LED control module, the AT control module, and the image control module. ), The backup process of the AT control module may be prioritized over the backup process of the game history control module, the sound / LED control module, and the image control module. That is, the backup process of the AT control module may be performed with the highest priority over the backup process of other program modules by performing the backup process of the AT control module in the portion of St0-1 to St0-5 in FIG. . As a result, in the startup process (sub), the return process is not performed on condition that all backup data is normal, and only the function related to the program module whose backup data is normal is performed. Even if an unexpected power interruption occurs when backup processing related to other program modules is performed after the backup processing of the game is completed, it is possible to secure at least highly important backup data related to the interests of the player It becomes possible.

  In this embodiment, for each program module, check data for determining whether backup data is normal is created using data used in the program module (Sm4, Sm9, Sm14, Sm19 and St0-4, St4, St9, St14 in FIG. 36).

  Therefore, even if the program structure is composed of a plurality of program modules and the backup process is performed by a common method regardless of the model, the program development man-hours can be reduced.

  Further, in this embodiment, for each program module, it is determined whether backup data based on data used in the program module is normal, and it is determined that all backup data is normal. Based on the above, a return process is performed (the portions of Sa8, Sa12, Sa17, Sa21 in FIGS. 8 to 10 and the portions of Sn6-4, Sn9, Sn13, and Sn17 in FIGS. 22 to 23). Therefore, even if the start address is specified so that the start address of the data creation area of the backup data differs for each program module, the return process can be performed reliably.

  In the above embodiment, in the startup process (main) and the startup process (sub), the checksums of the program modules are all returned to the state before the power interruption on condition that the checksums match. Not limited, if there is a program module with a checksum that matches and a program module with a checksum that does not match, only the functions related to the program module with a matching checksum are restored to the state before power interruption, or all The configuration described in the above embodiment may be applied to a gaming machine that returns to the state before power interruption with respect to the function.

  In particular, as in the case of the game history control module of the above-described embodiment, when performing control of a game history that allows a privilege to be granted by external output, not only the game machine, checksums of other program modules If the checksums of the game history control modules match even if the backup data is not normal, that is, if the backup data is not normal, only the game history control module returns to the state before the power interruption, so Even if has been initialized, the game history that has been returned can be output to the outside so that a privilege that does not depend on the initialized contents of the production can be received. In the case of such a configuration, it is preferable to preferentially create and store the backup data of the game history control module at the time of power interruption, as in the above embodiment, so that other program modules can be Even if it is not backed up normally, there is an increased possibility that the game history control module has been backed up normally, the power interruption will not be performed normally, and other effects will be initialized as described above Even if it is done, the possibility that the game history module will return to the state before the power interruption is increased, and it is possible to receive benefits that do not depend on the initialized production contents by outputting the returned game history to the outside Increases nature.

  Also, in the case of controlling a game history such as a game history control module in which not only the gaming machine but also a bonus can be given by external output, only the game history control module is different from other program modules. For other program modules, the checksums of the other program modules are restored to the state before the power interruption while the checksums of the program modules are all matched. Regardless of whether or not they match, if the checksum of the game history control module matches, it may be configured to be able to return to the state before the power interruption, and with this configuration, a program other than the game history control module If the module is not normal, other effects will be initialized, If the checksum of the technique history control module is normal, it is possible to restore only the game history control module. By outputting the restored game history to the outside, it is possible to grant a privilege that does not depend on the initialized contents of the production. Can be received.

  Even in such a configuration, it is preferable to preferentially create and store the backup data of the game history control module at the time of power interruption, and this makes it possible for other program modules not to be backed up normally. Even if there is, the possibility that the game history control module will be backed up normally will increase, and even if the power interruption is not performed normally and other production contents are initialized as described above, the game history module Is likely to return to the state before the power interruption, and by outputting the returned game history to the outside, the possibility of receiving a privilege that does not depend on the initialized contents of the production increases.

  In this embodiment, the backup data is stored in the backup RAM by performing a common data conversion process regardless of which program module is used as the backup data (Sm2, Sm7,. (Sm12, Sm17, and St0-2, St2, St7, St12 in FIG. 36 are the parts that perform data conversion shown in FIG. 38). Therefore, the number of program development steps can be reduced.

  In the above embodiment, data conversion for adding 8-bit data is performed. However, the present invention is not limited to this embodiment, and the configuration shown in the above embodiment is applied to a slot machine that performs data conversion processing by another method. It may be applied.

  In this embodiment, the program module performs backup processing of backup data based on data used in the AT control module in preference to an image control module other than the AT control module for performing processing related to AT (see FIG. The part of St6 to St10 in 36 is given priority over the process of St11 to St15, and the part of the modified example regarding the order of the backup process). Therefore, it is possible to reliably back up the program module having a high importance related to the player's profit.

  In the above embodiment, an example in which an AT control module is applied as a game control program module has been described. However, the present invention is not limited to this embodiment. For example, backup processing of a program module that performs processing related to RT is given priority. The configuration shown in the above embodiment may be applied to a gaming machine that performs backup processing of program modules related to games other than AT.
