Description

  The present invention relates to a slot machine capable of generating a predetermined winning according to a display result of a variable display device capable of variably displaying a plurality of types of identification information each identifiable, and is particularly advantageous for a player such as a big bonus. The present invention relates to a slot machine having a special gaming state.

  Conventionally, for example, a combination of symbols corresponding to a special prize (for example, a combination of “7-7-7”, hereinafter also referred to as a special role) is aligned on a winning line on a variable display device composed of a plurality of reels by a player's stop operation. In general, a slot machine that shifts to a special game state advantageous to a player such as a big bonus is common.

  In this type of slot machine, in this type of slot machine, an internal lottery is performed to determine whether or not a prize is allowed to occur, and when the prize is won in this internal lottery, the variable display device is won. In general, control is performed so that the corresponding symbol combinations are aligned, and control is performed so that the symbol combinations that are not won in the internal lottery are not aligned, and a winning is generated according to the aligned symbol combinations. Is.

  In addition, in order to raise the expectation for the winning of the special role described above, when the special role is won, more reels are operated at the timing of the stop operation positions than when the special role is not won. By determining the specific display result as the display result derived when the stop operation is performed, when the specific display result is derived, the player is likely to be selected as a special role. A slot machine has been proposed (see, for example, Patent Document 1).

In addition, when any of the winnings is not permitted by the predetermining means, that is, in the state of occupying most of the normal times, the first or second specific display result is not derived, and the predetermining means Since it is possible to derive the first or second specific display result by making a decision to allow the occurrence of the first or second specific prize winning, it is influenced by the skill of the player. Therefore, it is possible to derive a specific display result at an appropriate rate.
Further, when the second specific display result is derived in the specific variable display area by operating the derivation operation means corresponding to the specific variable display area at the specific operation timing, the first specific display result is Since it is more likely that a special prize will be allowed than when it was derived, even if you are playing a game while always operating the derivation operation means at the same operation timing, the display result derived at that time Thus, it is possible to change the player's expectation that a special prize is allowed to occur.
In addition, an operation timing capable of generating a predetermined prize winning, an operation timing capable of generating a first specific prize winning and an operation timing capable of generating a second specific prize winning are: There is no duplication, and it is impossible to operate the derivation operation means aiming at the predetermined specified winning award and the first specific award winning or the second specified award winning at the same time. Since a larger number of game values are given than when the second specific prize is awarded, the operation at the operation timing that can actively generate the predetermined prize, ie, the first and first It is possible to prompt the player to perform an operation at an operation timing to miss the 2 specific prizes, and as a result, it is possible to increase the chances of deriving the first and second specific display results. Can be effectively enhanced player's expectation for the generation of special pay is allowed.
If the first operation timing and the second operation timing do not overlap, and the first operation timing and the third operation timing do not overlap, the second operation timing and the third operation timing are used. May be overlapping or non-overlapping.
Further, an expected value of gaming value when the operation of the derivation operation means is performed at the first operation timing (probability determined to allow the generation of the predetermined prize-winning × the prize is given along with the occurrence of the predetermined prize-winning It is determined that the number of game values) is to allow the expected value of game value to be obtained when the operation of the derivation operation means is performed at the second or third operation timing (occurrence of the first specific awarded prize) Probability to be performed x number of game values to be awarded with the occurrence of the first specific prize-winning, or probability to be determined that the second specific prize-winning is allowed to occur x occurrence of the second specific prize-winning (The number of game values to be awarded) is increased, and in this way, the operation at the operation timing at which the predetermined prize can be generated more actively, that is, the first and the first Missed 2 specific grants It is possible to promote the operation in the work timing to the player.

An interrupt is generated based on the input of the output V blank interrupt signal, and the V blank interrupt process is executed.

  Further, the CPU 91a is based on inputs of a transfer end interrupt signal, a read end interrupt signal, and a drawing end interrupt signal that are output from the graphic controller 200 at the end of transfer processing, reading processing, and drawing processing, which will be described later. An interrupt is generated to execute a transfer end interrupt process, a read end interrupt process, and a drawing end interrupt process. The transfer end interrupt signal is connected to the normal signal input terminal in addition to the interrupt terminal of the CPU 91a, and the CPU 91a can detect the transfer end interrupt signal via the input port in addition to the interrupt terminal. It is like that.

  Also, when an unused interrupt occurs in the CPU 91a, an unused interrupt process for immediately returning to the original process is executed.

  Further, unlike the CPU 41a, when an interrupt is generated based on the input of the strobe signal (INT), the CPU 91a interrupts the process even when an interrupt process based on another interrupt is being executed. The command reception interrupt process is executed at the top, and even if another interrupt occurs at the same time, the command reception interrupt process is executed with the highest priority. During execution of the interrupt process, interrupts other than the interrupt based on the input of the strobe signal (INT) are prohibited.

  The sub-control unit 91 is also supplied with backup power at the time of a power failure, and while the backup power is supplied, the CPU 91a performs a refresh operation so that the data stored in the RAM 91c is retained. It has become.

  Further, backup power is supplied to the clock device 97 in the event of a power failure, and the date / time information is not reset unless the power failure state continues for 2 to 3 days, for example.

  Next, details of wiring connection states between the game control board 40 and various game electronic components connected to the game control board 40 will be described with reference to FIG. FIG. 4 is a schematic view showing a wiring connection state between the game control board 40 and the game electronic components connected to the game control board 40.

A start switch 7 that is operated, stop switches 8L, 8C, and 8R that are operated when the rotation of the reels 2L, 2C, and 2R is stopped, a inserted medal sensor 31 that detects a medal inserted to set a bet number; Reel sensors 33L, 33C, 33R for detecting the rotation of the reels 2L, 2C, 2R, a payout sensor 35 for detecting medals to be paid out when a winning occurs, and an effect control board 90 are shown, and other switches, Illustrations of sensors and the like are omitted.

  The gaming electronic components 5, 6, 7, 8, 31, 32 L, 32 C, 32 R, 33 L, 33 C, 33 R, 34, and 35 excluding the effect control board 90 send signals related to the progress of the game to the game control board 40. It is an electronic component that inputs and outputs. The signal related to the progress of the game is, for example, an operation for setting the number of bets to make the game startable, an operation for starting the game, or an operation for deriving the display results of the reels 2L, 2C, and 2R. Such as signals output to the game control board 40 in accordance with the progress of the game, detection of inserted medals, detection of the reference position of the reels, detection of the payout medals, etc., output from the game electronic components in accordance with the progress of the game And a signal input to the game control board 40, a drive signal for driving the reels 2L, 2C, 2R according to the detection of the start operation, and a hopper for paying out medals when a winning occurs. A signal that is output from the game control board 40 in accordance with the progress of the game and that is input to the game electronic component.

  These gaming electronic components 5, 6, 7, 8, 31, 32L, 32C, 32R, 33L, 33C, 33R, 34, and 35 output signals to the game control board 40 as the game progresses. 1 electronic component and a second electronic component to which a signal from the game control board 40 is input as the game progresses.

  Specifically, the single bet switch 5 and the MAXBET switch 6 that are operated when setting the bet number and the inserted medal sensor 31 that detects a medal inserted to set the bet number are the operation or the medal of the medal. This is a first electronic component that outputs a BET signal to the game control board 40 based on the detection. Since the main control unit 41 performs the betting number setting process based on the reception of the BET signal, the betting number cannot be set without these electronic components. That is, since the game cannot be started unless the bet number is set, the one-sheet BET switch 5, the MAXBET switch 6, and the inserted medal sensor 31 are electronic components for games necessary for the progress of the game.

  The start switch 7 that detects an operation for starting a game is a first electronic component that outputs a start signal to the game control board 40 based on the detection of the operation. Since the main control unit 41 performs a process for starting the game (reel rotation process or the like) based on the reception of the start signal, the game cannot be started without this electronic component. That is, the start switch 7 is a game electronic component necessary for the progress of the game.

  Stop switches 8L, 8C, and 8R that detect an operation for deriving the display results of the reels 2L, 2C, and 2R are first electronic components that output a stop signal to the game control board 40 based on the detection of the operation. is there. The main control unit 41 performs processing for deriving the display result by stopping the rotation of the corresponding reels 2L, 2C, and 2R based on the reception of the stop signal. The display result of cannot be derived. That is, the stop switches 8L, 8C, and 8R are game electronic components necessary for the progress of the game.

  The reel sensors 33L, 33C, and 33R that detect the rotation of the reels 2L, 2C, and 2R are first electronic components that output a detection signal for the reference position of the reel to the game control board 40. The main control unit 41 does not have this electronic component because it performs processing to stop rotation by grasping the positions of the symbols of the corresponding reels 2L, 2C, and 2R based on reception of the detection signal of the reference position of the reel. In addition, derivation of display results of each reel 2L, 2C, 2R, determination of winning, etc. cannot be performed. That is, the reel sensors 33L, 33C, and 33R are game electronic components necessary for the progress of the game.

  The payout sensor 35 that detects a medal to be paid out when a winning occurs is a first electronic component that outputs a medal payout signal to the game control board 40 based on the detection of the medal. The main control unit 41 performs a payout process for paying out the number of medals according to the generated prize based on the reception of the payout medal detection signal. Therefore, the number of medals according to the number of prizes generated without this electronic component. Cannot be paid out. That is, the payout sensor 35 is a game electronic component necessary for the progress of the game.

  The reel motors 32L, 32C, and 32R that rotate the reels 2L, 2C, and 2R are second electronic components to which a drive signal output from the game control board 40 is input. The reel motors 32L, 32C, and 32R rotate the reels 2L, 2C, and 2R based on the input of the drive signal output from the game control board 40 and start the symbol variation display. Even if the reels 2L, 2C, and 2R are not actually rotated based on the above, the main control unit 41 receives the signals from the reel sensors 33L, 33C, and 33R after outputting the reel drive signals. The game can be controlled to proceed as the reel rotates. However, the timing at which signals are input to the game control board 40 from the reel sensors 33L, 33C, 33R is an error unless the reel drive signal is output. In order to measure the output timing of the signal based on the detection of the rotation of the reel, a reel drive signal is required. That is, the reel motors 32L, 32C, and 32R are game electronic components necessary for the progress of the game.

  The hopper motor 34 that drives the hopper tank that pays out medals is a second electronic component that receives a drive signal output from the game control board 40 in response to the occurrence of a prize. The hopper motor 34 drives the hopper tank based on the input of the drive signal output from the game control board 40 and pays out medals, but does not actually drive the hopper tank based on the signal input. Even if the main control unit 41 outputs the hopper tank drive signal, the signal from the payout sensor 35 is input, so that the game can be controlled so that the medal is paid out. it can. However, the timing at which a signal is input from the payout sensor 35 to the game control board 40 is an error unless the hopper tank drive signal is output. Therefore, when the game is advanced by the driving tool described above, In order to measure the output timing of the signal based on the detection, a driving signal for the hopper tank is required. That is, the hopper motor 34 is a gaming electronic component necessary for the progress of the game.

  First, the first electronic component will be described in detail. One of the BET switch 5, the MAXBET switch 6, or the connector of a cable provided between the inserted medal sensor 31 and the game control board 40 is driven into a connector. If the BET signal is illegally output from the driving tool to the game control board 40, the bet number may be set without performing the bet number setting operation. When a connector of a driving tool is connected to one of the connectors of a cable provided between the start switch 7 and the game control board 40, and a start signal is illegally output from the driving tool to the game control board 40 There is a possibility that the game is started without performing the game start operation. The connector of the driving tool is connected to one of the connectors of the cable provided between the stop switches 8L, 8C, 8R and the game control board 40, and the stop signal is illegally transmitted from the driving tool to the game control board 40. If output, the rotation of the reel may be stopped without performing a stop operation. The connector of the driving tool is connected to one of the connectors of the cable provided between the reel sensors 33L, 33C, 33R and the game control board 40, and the reel rotation signal is illegal from the driving tool to the game control board 40. Is output to the reels 2L, 2C and 2R without rotating the reels, there is a risk that the display result of each reel, determination of winning, etc. may be performed. The connector of the driving tool is connected to one of the connectors of the cable provided between the payout sensor 35 and the game control board 40, and a medal payout signal is illegally output from the driving tool to the game control board 40. There is a possibility that the medals are counted without paying out medals.

  The second electronic component will be described in detail. The game control board 40 is released by disconnecting one of the connectors of the cable provided between the reel motors 32L, 32C, 32R and the game control board 40. When the driving signal output from the game control board 40 can be acquired by the driving tool, the timing at which the driving signal of the reel is output from the game control board 40 can be specified on the driving tool side, so game control is originally performed from the reel sensors 33L, 33C, 33R There is a possibility that the reel rotation detection signal input to the substrate 40 may be output from the driving tool at an appropriate timing after the reel rotation. In addition, the drive signal output from the game control board 40 can be acquired by a driving tool or the like after the connection at any of the connectors of the cable provided between the hopper motor 34 and the game control board 40 is released. Then, since the timing at which the driving signal of the hopper tank is output from the game control board 40 can be specified on the driving instrument side, the payout medal detection signal originally input from the payout sensor 35 to the game control board 40 is sent from the driving tool to the hopper tank. May be output at an appropriate timing after driving.

  As described above, the signals that are output from the first electronic components 5, 6, 7, 8, 31, 33L, 33C, 33R, and 35 according to the progress of the game and that are originally input to the game control board 40 are provided. When output from the driving tool, the main control unit 41 can perform control to advance the game based on the reception of the signal, and is output from the game control board 40 according to the progress of the game. When a signal input to the second electronic component 32L, 32C, 32R, 34 is input to the driving tool, on the driving tool side, an output timing of a signal output from the main control unit 41 after driving the reel motor or the hopper motor When a new signal is input to the main control board 40 based on this, the main control unit 41 plays the game based on the reception of the signal. It is possible to perform control of the line, there is a possibility that fraud such causes game automatically proceed is performed. Therefore, in this embodiment, various measures are taken in order to prevent an illegal act due to the connection of the driving tool.

  In this embodiment, it is difficult to connect the driving tool by restricting the release of the connector connection between the game control board 40 and the game electronic component. Specifically, the connector connection between the game control board 40 and the inserted medal sensor 31, that is, the connection between the board side connector 620a of the game control board 40 and the cable side connector 610a of the cable 600a, the cable side connector 611a of the cable 600a. And the connection between the board-side connector 621a of the operation part relay board 110 and the connection between the board-side connector 622g of the operation part relay board 110 and the cable-side connector 612g of the cable 601g are restricted from being released from each other. .

  Further, by restricting the release of the connector connection between the game control board 40 and the effect control board 90, it is difficult to release the connection between the game control board 40 and the effect control board 90. Specifically, the connector connection between the game control board 40 and the effect control board 90, that is, the connection between the board side connector 620d of the game control board 40 and the cable side connector 610d of the cable 600d, the cable side connector 611d of the cable 600d. And the board side connector 621d of the production relay board 80, the board side connector 622p of the production relay board 80 and the cable side connector 612p of the cable 601p, the cable side connector 613p of the cable 601p and the board side of the production control board 90 The connection with the connector 623p is restricted from releasing the connection between these connectors.

  The connection between the board-side connector and the cable-side connector is restricted from being released by a connector restricting member (not shown). The connector restricting member is configured to be able to restrict the removal of the cable-side connector from the board-side connectors connected to each other. The configuration is arbitrary and can be variously changed as long as it is configured to leave a trace when the connection release restriction state is released.

  Specifically, for example, it may be a cover body that is formed separately from the board-side connector and the cable-side connector and that can be attached and removed in a connected state to restrict the connector from being removed. Alternatively, it may be a locking portion that is provided on at least one of the board-side connector and the cable-side connector and that cannot be detached from each other when the connectors are connected to each other, or the board-side connector is mounted. In a restricting portion or the like that is provided in a substrate storage case or the like that can store a substrate to be connected, and that forms a connection release restriction state that restricts connector removal when the substrate is stored in the substrate storage case and sealed. It may be an adhesive or the like that bonds the connectors connected to each other.

  Next, a configuration around the disconnection monitoring IC 50 in the game control board 40 will be described.

  The game control board 40 is supplied with + 5V DC voltage generated by the voltage generation circuit of the power supply board 100. The + 5V DC voltage supplied from the power supply board 100 is supplied to the power supply terminal (VDD) as a drive power supply for the disconnection monitoring IC 50, and also branches on the game control board 40 as shown in FIG. 40 and the operation unit relay board 110 via the cable 600a, the operation unit relay board 110, the operation unit relay board 110 and the insertion medal sensor 31 via the cable 601g, and then folded back by the insertion medal sensor 31, Returning to the game control board 40 via the cable 601g, the operation unit relay board 110, and the cable 600a, and further connecting the game control board 40 and the production relay board 80 to the cable 600d, the production relay board 80, and the production relay board 80 Via the cable 601p for wiring and connecting the effect control board 90, the effect control board 90 is further turned back. Te, cable 601P, directing the relay board 80, so that via the cable 600d to return to the game controller board 40 again, is input as a connection signal to the input terminal disconnection monitoring IC50 (IN).

  For this reason, in this embodiment, the board-side connector 620a of the game control board 40 and the cable-side connector 610a of the cable 600a are connected, and the cable-side connector 611a of the cable 600a and the board-side connector 621a of the operation unit relay board 110 are connected. The connection of the board side connector 622g of the operation unit relay board 110 and the cable side connector 612g of the cable 601g, the connection of the board side connector 620d of the game control board 40 and the cable side connector 610d of the cable 600d, and the cable side connector of the cable 600d 611d and the board-side connector 621d of the production relay board 80, the board-side connector 622p of the production relay board 80 and the cable-side connector 612p of the cable 601p, the cable-side connector 613p of the cable 601p and the production control board The connection signal input to the input terminal (IN) of the disconnection monitoring IC 50 is cut off by releasing any one of the connection to the board-side connector 623p of 0, and thus the disconnection monitoring IC 50 is connected to the game control board. 40 and the inserted medal sensor 31 and the disconnection between the game control board 40 and the effect control board 90 are detected. That is, when the connection between the connectors between the game control board 40 and the inserted medal sensor 31 and the connection between the game control board 40 and the effect control board 90 are released even at one place, the disconnection monitoring IC 50 detects the disconnection. It has come to be.

  Further, as shown in FIG. 5, the + 5V DC voltage supplied from the power supply board 100 branches on the game control board 40 and is connected to the ground level on the power supply board 100 side. A capacitor C1 is provided. D1 is a diode for preventing backflow. As a result, a DC voltage of +5 V can be stored in the capacitor C1, and when the power supply to the slot machine 1 is cut off, the voltage stored in the capacitor C1 can be supplied as a backup power source for driving the disconnection monitoring IC 50. Thus, the disconnection monitoring IC 50 can detect disconnection between the game control board 40 and the inserted medal sensor 31 and between the game control board 40 and the effect control board 90 regardless of whether it is during energization or during a power failure. It has become.

  In the slot machine 1 of this embodiment, the medal payout rate changes according to the set value, and the winning probability of the internal lottery described later is determined according to the set value. Hereinafter, the setting value changing operation will be described.

  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 power is turned on with the setting key switch 37 in the ON state, 1 is displayed as the initial value of the setting value on the setting value display 24, and the setting change mode in which the setting value can be changed by operating the reset / setting switch 38 is set. Transition. When the reset / setting switch 38 is operated in the setting change mode, the setting value displayed on the setting value display 24 is updated one by one (when further operation is performed from the setting 6, the setting value is returned to the setting 1). . When the start switch 7 is operated, the set value is confirmed, and the confirmed set value is stored in the RAM 41c of the main control unit 41. Then, when the setting key switch 37 is turned off, the state shifts to a state in which the game can proceed.

  In the slot machine 1 of the present embodiment, the CPU 41a makes a disconnection flag confirmation request to the disconnection monitoring IC 50 at the time of activation, acquires the storage state of the disconnection flag based on a reply from the disconnection monitoring IC 50, and disconnects the disconnection flag. When the flag is stored, it is determined that the disconnection is abnormal, and a disconnection error error code is set in the register to control the disconnection error, thereby disabling the progress of the game. Unlike the normal error state, the disconnection abnormality error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated, and the area of the RAM 41c that is being used by the CPU 41a is not changed. All the areas other than the initialization area are initialized and cannot be restored to the original state, and are not canceled until a new setting value is set in the setting change mode described above.

  Further, the CPU 41a also acquires the storage state of the disconnection flag of the disconnection monitoring IC 50 in the timer interrupt process that is periodically executed. If the disconnection flag is stored, it is determined that the disconnection is abnormal as in the start-up. Then, the disconnection error error code is set in the register to control the disconnection error, and even in this case, the original state cannot be restored, and it is canceled until a new set value is set in the setting change mode described above. It will not be done.

  In the slot machine 1 of the present embodiment, when the CPU 41a of the main control unit 41 detects a voltage drop signal, a power interruption interrupt process is executed. In the power interruption interrupt processing, the register is saved in a stack of a RAM 41c, which will be described later, and data for destructive diagnosis (5AH in this embodiment) in which any bit is 1 in the RAM 41c of the main control unit 41, that is, other than 0 In addition to storing specific data, the RAM parity adjustment data is calculated so that the RAM parity based on the data stored in all areas of the RAM 41c becomes 0, and stored in the RAM 41c. The RAM parity is a value calculated as an exclusive OR of values stored in each bit of the corresponding area (all areas in this embodiment) of the RAM 41c. Therefore, if the RAM parity based on the data stored in all areas of the RAM 41c is 0, the RAM parity adjustment data is 0, and the RAM parity based on the data stored in all areas of the RAM 41c is 1. In this case, the RAM parity adjustment data is 1.

  The CPU 41a calculates the RAM parity based on the data stored in all areas of the RAM 41c at the time of activation, confirms the value of the destructive diagnosis data, the RAM parity is 0, and the destructive diagnosis On the condition that the data value is also correct, the processing state of the CPU 41a is restored to the state before the power interruption based on the data stored in the RAM 41c. If the data value is not correct, it is determined that the RAM is abnormal, and a RAM abnormal error code is set in the register to control the RAM abnormal error, thereby disabling the progress of the game. As in the case of the disconnection abnormality error, the RAM abnormality error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated, and the area used by the CPU 41a in the area of the RAM 41c is not changed. All the areas other than the initialization area are initialized and cannot be restored to the original state, and are not canceled until a new setting value is set in the setting change mode described above.

  Further, the CPU 41a determines whether or not the bet number set in the game in the internal lottery process described later is a bet number corresponding to the gaming state. And even when the set bet number is not the bet number according to the gaming state, it is determined that the RAM is abnormal, and the RAM abnormal error code is set and controlled to the RAM abnormal error state, so that the progress of the game is disabled. It is like that. As described above, the RAM abnormal error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated, and all the areas of the RAM 41c except for the area in use by the CPU 41a. The area is initialized and cannot be restored to the original state, and is not released until a new set value is set in the setting change mode described above.

  In addition, the CPU 41a determines whether or not the bet number set in the internal lottery process described later is a bet number according to the gaming state, and whether or not the set value used for the internal lottery is an appropriate value. judge.

  Even when the set bet number is not the bet number according to the gaming state, or when the set value used for the internal lottery is not an appropriate value, it is determined that the RAM is abnormal and the RAM abnormal error code is set and the RAM is set. The game is controlled to an abnormal error state and the progress of the game is disabled. As described above, the RAM abnormal error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated, and all the areas of the RAM 41c except for the area in use by the CPU 41a. The area is initialized and cannot be restored to the original state, and is not released until a new set value is set in the setting change mode described above.

  Further, when the CPU 41a returns the processing state to the state before the power interruption based on the data stored in the RAM 41c at the time of activation, whether or not the winning flag of any special role is set, that is, the power interruption It is determined whether or not any special role has been won before, and if the winning flag for any special role is set, a power-on command is sent to indicate the special role and the sub-control is sent. Instruct the part 91 to notify that the special role is won. On the other hand, if the winning flag for any special combination is not set, a power-on command indicating that the special combination is not won is transmitted. When the sub-control unit 91 receives a power-on command from the main control unit 41 at the time of startup, the sub-control unit 91 performs a notification effect indicating that the special role is won by the liquid crystal display 51 or the like if the command is a power-on command indicating that the special role is won. Then, it continues until the special combination wins, whereas if it is a power-on command indicating that the special combination is not won, it will return to the backed-up performance state.

  Further, the sub-control unit 91 produces the effect even if the backup is normal until it receives a power-on command or an initialization command indicating that the control state of the main control unit 41 has been initialized as will be described later. Without returning to the state, even if another command is received, the production is not controlled accordingly. For this reason, even if the command transmission lines of the main control unit 41 and the sub control unit 91 are disconnected at the time of startup and the main control unit 41 and the sub control unit 91 are connected thereafter, the sub control unit 91 can Since the initialization command is not received, the production control is not performed, and even if the command transmission line of the main control unit 41 and the sub control unit 91 is disconnected at the time of activation, the power-on command is issued on the sub control unit 91 side. It is impossible to avoid the reception of the special announcement and the announcement effect indicating that the special role is won.

  That is, when the main control unit 41 is activated, it returns to the state before the power interruption, and when the special role is elected before the power interruption, a power-on command indicating that the special role is elected is transmitted. When the sub-control unit 91 receives the power-on command indicating the winning, the sub-control unit 91 executes a notification effect indicating the winning of the special role, and avoids receiving the power-on command on the side of the sub-control unit 91 to notify the winning of the special role. Since it is impossible to avoid the execution of the production, when the main control unit 41 is restored to the state before the power interruption and the special role is elected before the power interruption as described above, The winning of special role will be notified.

  In the slot machine 1 according to the present embodiment, the prescribed number of bets that can be set according to the gaming state is determined as described above, and the prescribed number of bets that are determined according to the gaming state is set. It becomes possible to start the game on the condition. In this embodiment, as will be described later, there are a regular bonus and a normal gaming state as the gaming state, and 1 is defined as the prescribed number of bets corresponding to the regular bonus, and the regulation of the betting number corresponding to the normal gaming state. Three is defined as the number. For this reason, when the gaming state is a regular bonus, the game can be started when the betting number is set to 1, and when the gaming state is the normal gaming state, the game is started when the betting number is set to 3. Can be started. In this embodiment, when a specified number of bets corresponding to the gaming state is set, all winning lines L1 to L5 are activated, and the specified number corresponding to the gaming state is If it is 1, all winning lines L1 to L5 are activated when 1 is set as the bet number, and if the specified number is 3 according to the gaming state, 3 is set as the bet number. All winning lines L1 to L5 are activated.

  In the slot machine 1 of this embodiment, when all the reels 2L, 2C, 2R are stopped, the activated pay line (in the present embodiment, all the pay lines are always enabled. The activated winning line is simply referred to as a winning line), and a winning combination is obtained when a combination of symbols called a combination is arranged on the winning line. 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 can start the next game without the need to set the number of bets. There are a game combination and a special combination with a transition of the game state. 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 is carried over to the next game. It becomes.

  FIG. 6 is a diagram showing a winning combination table. The winning combination table is stored in advance in the ROM 41b of the main control unit 41, and the combination numbers (0 to 18) assigned in the order in which the lottery is performed corresponding to combinations of combinations and combinations to be selected in the internal drawing. ) Is registered.

  As the role in this slot machine 1, special bonuses include big bonus (1), big bonus (2), regular bonus, small roles such as watermelon, cherry, 1 (1), 1 (2), bell, Replay is defined as a re-playing role. In addition, combinations of combinations in the slot machine 1 include big bonus (1) +1 (1), big bonus (2) +1 (1), regular bonus + 1 (1), big bonus (1) +1 ( 2) Big bonus (2) +1 (2), Regular bonus + 1 (2), Bell + Watermelon, Bell + Cherry, Bell + 1 (1), Bell + 1 (2). That is, the total number of combinations of combinations and combinations is 19.

  In the slot machine 1 according to the present embodiment, as shown in FIG. 6, the combination and combination of combinations that are subject to the lottery differ depending on whether the gaming state is the normal gaming state or the regular bonus. Furthermore, when the gaming state is the normal gaming state, it depends on whether any special role is being carried over (whether any special role has already been set in the winning flag of the special role). The combination of combinations and combinations that are subject to lottery are different. In this embodiment, a state number corresponding to the gaming state is assigned, and when performing an internal lottery, a state number corresponding to the current gaming state is set, and a role to be a lottery object is determined according to this state number. It becomes possible to specify. Specifically, when no special combination is carried over in the normal gaming state, “0” is set as the state number, and when any special combination is carried over in the normal gaming state, “1” is set as the state number, and “2” is set as the state number in the case of a regular bonus.

  As shown in FIG. 6, when the gaming state is the normal gaming state and no special role is carried over, that is, when the state number is set to “0”, the big bonus (1), big Bonus (2), Regular Bonus, Big Bonus + 1 (1), Big Bonus (2) +1 (1) Regular Bonus + 1 (1), Big Bonus (1) +1 (2), Big Bonus (2) +1 (2), regular bonus +1 (2), replay, watermelon, cherry, 1 (1), 1 (2), bell, that is, the combination of the combination of combination number 0-14 and combination of combination It becomes a target. Further, when the gaming state is the normal gaming state and any special role is carried over, that is, when the state number is set to “1”, replay, watermelon, cherry, 1 (1) One (2), a bell, that is, a combination of a combination of combination numbers 9 to 14 is a target of internal lottery. When the game state is a regular bonus, that is, “2” is set as the state number, bell, bell + watermelon, bell + cherry, bell + 1 (1), bell + 1 (2), that is, role Combinations and combinations of combinations after number 14 are subject to internal lottery.

  The watermelon is awarded when the combination of “watermelon-watermelon-watermelon” is aligned on any of the winning lines in any gaming state, and six medals are paid out. Cherry is awarded when the symbol “Cherry” is derived on any of the winning lines for the left reel in any gaming state, and five medals are paid out. If the “Cherry” symbol stops at the upper or lower level of the left reel, the combination of cherries will be aligned on the two winning lines L2 and L4 or the winning lines L3 and L5. Since winning a cherry on the winning line, ten medals will be paid out. One (1) is awarded when a combination of “white 7-orange-cherry” is aligned on any of the winning lines in any gaming state, and one medal is paid out. One (2) is awarded when a combination of “Red 7-Cherry-Cherry” is aligned on any of the winning lines in any gaming state, and one medal is paid out. The bell is awarded when a combination of “bell-bell-bell” is arranged on any of the winning lines in any gaming state, and 12 medals are paid out.

  Replay is awarded when a combination of “replay-replay-replay” is arranged on any of the winning lines in the normal gaming state. When a replay prize is won, a replay game is provided in which a game can be played without setting the number of bets. When a replay is won, the medals will not be paid out, but the next game can be started without setting the number of bets again, so the number of bets no longer required to be set in the next game (the regular bonus will not be replayed and will always be 3) This is substantially the same as when three corresponding medals are paid out.

  The regular bonus is awarded when a combination of “white 7-white 7-red 7” is arranged on any of the winning lines in the normal gaming state. When the regular bonus is won, the gaming state shifts from the normal gaming state to the regular bonus. The regular bonus ends when 12 games are consumed, or when 8 games are won (any kind of combination is possible), whichever comes first. While the game state is in the regular bonus, the regular bonus medium flag is set in the RAM 41c.

  The big bonus is awarded when a combination of “red 7-red 7-red 7” or a combination of “white 7-white 7-white 7” is arranged on any of the winning lines in the normal gaming state. When the big bonus is won, the gaming state shifts to the big bonus. In this embodiment, the big bonus to be awarded when the combination of “red 7-red 7-red 7” is complete is the big bonus (1), and the combination of “white 7-white 7-white 7” is complete. The big bonus that is sometimes won is the big bonus (2). When the big bonus (1) wins, the gaming state shifts to the big bonus (1). When the transition to the big bonus (1) is made, the transition to the regular bonus is made at the same time as the transition to the big bonus (1). Then, it is controlled to the regular bonus repeatedly until the big bonus (1) ends. That is, during the big bonus (1), the regular bonus is always controlled. The big bonus (1) ends when the total number of medals paid out to the player in the big bonus (1) exceeds 465. At this time, the regular bonus is ended regardless of whether the regular bonus end condition is satisfied. While the gaming state is the big bonus (1), the big bonus (1) medium flag is set in the RAM 41c.

  When the big bonus (2) wins, the gaming state shifts to the big bonus (2). If you move to Big Bonus (2), you will be transferred to Regular Bonus at the same time as Big Bonus (2). Then, it is controlled to the regular bonus repeatedly until the big bonus (2) ends. That is, during the big bonus (2), the regular bonus is always controlled as in the big bonus (1). The big bonus (2) ends when the total number of medals paid out to the player in the big bonus (2) exceeds 300. At this time, the regular bonus is ended regardless of whether the regular bonus end condition is satisfied. While the gaming state is the big bonus (2), the big bonus (2) medium flag is set in the RAM 41c.

  When it is necessary to distinguish between the big bonus by “red 7-red 7-red 7” and the big bonus by “white 7-white 7-white 7”, the big bonus (1) and the big bonus (2 ). Further, the regular bonus, the big bonus (1), and the big bonus (2) described above may be simply referred to as “bonus”.

  Hereinafter, the internal lottery of the present embodiment will be described. 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 number for internal lottery (an integer from 0 to 16383) is acquired as described later. And, for each combination of combinations and combinations determined according to the gaming state, according to the obtained random number for internal lottery and the number of judgment values of each combination of combinations and combinations determined according to the gaming state and setting value Done. In this embodiment, based on the number of judgment values for each combination and combination of combinations, a range of determination values for each of the general combination and special combination, and a range of determination values for the combination of general combination and special combination is won. And the winning in the internal lottery is not exclusive, and a general combination and a special combination may be won simultaneously in one game. However, for special roles of different types, the range of determination values to be won in duplicate is not specified, and special types of different types are exclusively drawn.

  Each combination and combination of combinations determined according to the game state is referred to in the order of combination numbers registered in the winning combination table shown in FIG.

  When the gaming state is the normal gaming state and no special roles are carried over, that is, when the state number is set to “0”, the winning combination table is referred to and the combination of the combination numbers 0 to 14 is referred to. And combinations of combinations, that is, big bonus (1) [port number 0], big bonus (2) [port number 1] regular bonus [port number 2], big bonus (1) +1 (1) [port number 3] , Big bonus (2) + 1 (1) [number 4], regular bonus + 1 (1) [number 5], big bonus (1) + 1 (2) [number 6], big bonus (2 ) + 1 (2) [Position number 7], Regular bonus + 1 (2) [Position number 8], Replay [Position number 9], Watermelon [Position number 10], Cherry [Position number 11], 1 (1 ) [Combination number 12], 1 sheet (2) [Combination Number 13] and bell [Position number 14] are sequentially read out as target lotteries for internal lottery.

  When the gaming state is the normal gaming state and any special combination is carried over, that is, when the status number is set to “1”, the winning combination table is referred to and the combination numbers 9 to 14 roles and combinations of roles, that is, replay [role number 9], watermelon [role number 10], cherry [role number 11], 1 sheet (1) [role number 12], 1 sheet (2) [role number 13 ], [Bell number 14] are sequentially read out as a target combination for internal lottery.

  Further, when the game state is a regular bonus, that is, “2” is set as the state number, the winning combination table is referred to, and combinations of the combination of combination numbers 14-18 and combination, that is, the bell [portion number 14], Bell + watermelon [role number 15], bell + cherry [role number 16], bell + 1 (1) [role number 17], bell + 1 (2) [role number 18] are sequentially read out as target lots for internal lottery. .

  In the internal lottery, when the number of judgment values determined for the combination or combination of roles and the state number indicating the current gaming state are added to the random number for internal lottery, and the result of the addition overflows In addition, it is determined that the combination or combination of combinations is won.

  Then, when winning of any combination or combination of combinations is determined, the winning flag corresponding to the combination of combination or combination determined to be selected is stored in the internal winning flag storage work (iwin_flag) assigned to the RAM 41c. Set. The internal winning flag storage work (iwin_flag) consists of a 2-byte storage area, of which the upper byte is assigned as the special role storing work in which the special role winning flag is set, and the lower byte is general. It is assigned as a general role storage work in which a winning flag for a role is set. Specifically, if any of the roles 0-2 is elected (special role), the winning flag of the special role indicating that the special role is won is set in the special role storing work, and the general role is stored. Clear the winning flag set for the workpiece. In addition, when any of the role numbers 3 to 8 (special role + general role) is won, a special role winning flag indicating that the special role is won is set in the special role storing work. A winning combination flag indicating that the general combination is won is set in the general combination storing work. When any of the combination numbers 9 to 18 (general combination) is won, a general combination winning flag 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.

  The number of determination values of each combination and combination of combinations is read according to the storage address of the number of determination values registered in the role-specific table (not shown) stored in advance in the ROM 41b of the main control unit 41.

  The number of determination values may be 256 or more, and cannot be stored in one byte. Therefore, each determination value number is registered using a storage area of two bytes. The number of determination values is registered in correspondence with the above-described state number that can specify the gaming state. This is because even if the combination is the same combination or combination, the winning probabilities may differ depending on the gaming state. The number of determination values may be common regardless of the set value, or may be different depending on the set value. If the number of determination values is common regardless of the set value, a common flag is set (value is set to “1”).

  Also, the number of medals to be paid out when winning each winning combination is registered in the role-specific table. However, only the watermelon, 1 (1), 1 (2), and the bell, which are small roles, are the targets to which medals are paid out when winning a prize.

  Winning big bonuses and regular bonuses are accompanied by a transition of the gaming state and are not eligible for medal payout. The replay does not involve the payout of medals, but it is substantially the same as the payout of 3 medals since it is not necessary to insert medals for setting the bet amount in the next game (always the normal game state).

  The storage area for the number of determination values acquired based on the addresses registered in the role-specific table is provided in the address area assigned to the ROM 41 b of the main control unit 41.

  7 and 8 are diagrams showing an example of the relationship between the value of the random number for internal lottery, the number of determination values of each combination and combination of combinations, and winning. FIG. 7 shows a regular bonus when no special combination is carried over in the normal gaming state, FIG. 8A shows a special bonus when any special combination is carried over in the normal gaming state, and FIG. 8B shows a regular bonus. Each example is shown. 7, 8 </ b> A, and 8 </ b> B each show an example in which the set value is 6.

  For example, as shown in FIG. 7, when no special combination is carried over in the normal gaming state, a big bonus (1), a big bonus (2), a regular bonus, a big bonus (1) +1 (1 ), Big Bonus (2) +1 (1), Regular Bonus + 1 (1), Big Bonus (1) +1 (2), Big Bonus (2) +1 (2), Regular Bonus + 1 (2) , Replay, watermelon, cherry, 1 sheet (1), 1 sheet (2), bell will be subject to internal lottery. Further, in this embodiment, with the setting value 6, the number of determination values for each combination when no special combination is carried over in the normal gaming state is 8, 6, 12, 4, 8, 6, 8, 16 , 12, 2236, 192, 150, 150, 54, and 1362 are registered, and the big bonus (1), which is the target of the internal lottery first, adds the judgment value number 8 and the addition result overflows The winning combination is obtained when 16376 to 16383 are acquired as random numbers for internal lottery.

  Next, the big bonus (2) that is the subject of the internal lottery is obtained by adding 24, which is the sum of the judgment value number 8 of the big bonus (1) and the judgment value number 16 of the big bonus (2). The winning combination is obtained when 16360 to 16375 that will overflow are acquired as random numbers for internal lottery. Similarly, the regular bonus is obtained when 16348 to 16359 are acquired as random numbers for internal lottery, when the big bonus (1) +1 (1) and 16344 to 16347 are acquired as random numbers for internal lottery, Big bonus (2) + 1 (2), 16336-16343 was acquired as random numbers for internal lottery, Regular bonus +1 (1), 16330-16335 was acquired as random numbers for internal lottery Sometimes, Big Bonus (1) + 1 (2), 16322-16329 are acquired as random numbers for internal lottery, Big Bonus (2) + 1 (2), 16306-16321 are internal lottery 16294-16305 are random numbers for internal lottery when regular bonus + 1 (2) The replay is obtained when 14058-16293 is obtained as a random number for internal lottery, the watermelon is obtained when 13866-14057 is obtained as a random number for internal lottery, and the cherry is 13716 When ~ 13865 is acquired as a random number for internal lottery, 1 sheet (1) is acquired when 13666-13715 is acquired as a random number for internal lottery, and 1 sheet (2) is stored inside 13512-13565 When acquired as random numbers for lottery, the bells are determined to be winning when 12150 to 13511 are acquired as random numbers for internal lottery. When 0 to 12149 are acquired as random numbers for internal lottery, all combinations are lost.

  The approximate winning probability of each combination and combination of combinations calculated based on the number of determination values is as follows: Big Bonus (1), Big Bonus (2), Regular Bonus, Big Bonus (1) + 1 (1), Big Bonus (2) +1 (1), Regular Bonus + 1 (1), Big Bonus (1) +1 (2), Big Bonus (2) +1 (2), Regular Bonus + 1 (2), Replay , Watermelon, cherry, 1 sheet (1), 1 sheet (2), bell, 1/248, 1/1024, 1 / 11365.3, 1/496, 1/248, 1 / 2730.7, 1/12048, 1/1024, 1 / 11365.3, 1 / 7.33, 1 / 85.3, 1 / 19.2, 1 / 109.2, 1 / 303.4, 1 / 12.03 Become.

  In addition, as shown in FIG. 8A, when any special combination is carried over in the normal gaming state, only replay, watermelon, cherry, 1 (1), 1 (2), and bell In this embodiment, 2236, 192, 150, 168, 90 are determined as the number of determination values of each combination when any special combination is carried over in the normal gaming state at the set value 6. 1362 are registered, and the approximate winning probabilities of the respective roles are 1 / 7.33, 1 / 85.3, 1 / 109.2, 1 / 97.5, 1/182, 1/12. .03.

  In addition, as shown in FIG. 8B, in the regular bonus, only bell, bell + watermelon, bell + cherry, bell + 1 (1), bell + 1 (2) are subject to internal lottery. 15320, 192, 150, 168, 90 are registered as the number of judgment values for each of the combinations, and the approximate winning probabilities of the respective combinations are 1 / 1.07, 1 / 85.3, 1/109. .2, 1 / 97.5, 1/182.

  Next, stop control of the reels 2L, 2C, 2R will be described.

  The CPU 41a refers to the table index and table creation data stored in the ROM 41b when the reel starts rotating and when the reel stops and the reel that is still rotating still remains. Create a stop control table for each reel. 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, the start address of the area where the data for table creation is stored from the reference address (table_index) 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) The difference up to the address where the index data indicating is stored is 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 (table_index).

  Specifically, lose, replay, watermelon, cherry, 1 (1), 1 (2), bell, big bonus (1) (+ lose), big bonus (1) + replay, big bonus (1) + Watermelon, Big Bonus (1) + Cherry, Big Bonus (1) + 1 (1), Big Bonus (1) + 1 (2), Big Bonus (1) + Bell, Big Bonus (2) (+ Loss) Big Bonus (2) + Replay, Big Bonus (2) + Watermelon, Big Bonus (2) + Cherry, Big Bonus (2) + 1 (1), Big Bonus (2) + 1 (2), Big Bonus ( 2) + Bell, Regular Bonus (+ Loss), Regular Bonus + Replay, Regular Bonus (2) + Watermelon, Regular Bonus + Cherry, Regular Bo Scan +1 Like (1), +1 Like regular bonus (2), for each of the regular bonus + bell, index data indicating the leading address of the area table created data is stored is stored. Note that even if the winning status of the combination is different, the same control is applied (for example, the same control is applied when the big bonus (1) + replay is won and when the big bonus (2) + replay is won. In this case, the same address is stored as the index data. In such a case, the stop control table is created with reference to the same table creation data.

  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. In particular, in this embodiment, even when the stopped position of the stopped reel is the same, when the stopped operation position of the stopped reel is different, the address data of the different number of drawing frame data is registered for each rotating reel. Even if the stopped positions of the stopped reels are the same, it is possible to specify the required number of drawn frames according to the stop operation position of the stopped reels. 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) are defined for one reel. These areas are areas 1 to 21 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 1 to 21 (see FIG. 2) from the reel reference position are assigned to the symbols of each reel. The area numbers 1 to 21 are sequentially assigned to the symbols. 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 of each stored reel is expanded to create a stop control table for the unstopped reels.

  Next, when the CPU 41a effectively detects any one of the stop switches 8L, 8C, 8R corresponding to the rotating reel, the control for deriving the display result to the corresponding reel will be described. If any of the stop switches 8L, 8C, and 8R corresponding to the rotating reel is detected effectively, the area number of the stop operation position is based on the number of steps from the reel reference position when the stop operation is detected. And the number of sliding symbols corresponding to the area number of the specified stop operation position is obtained 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, an area (stop point in the figure) corresponding to the area number corresponding to the stop position ahead of the number of sliding frames from the area (stop operation point in the figure) corresponding to the area number of the stop operation position where the stop operation is detected is shown. It stops at the stop reference position (in this embodiment, the lower symbol area of the fluoroscopic window 3).

  The table index of this embodiment stores only one address as index data corresponding to one internal winning state in one gaming state. Furthermore, one table creation data includes one table data. Only one address is stored as the address of the storage area of the stop control table corresponding to the reel stop status (and the stop operation position of the stopped reel). That is, the table creation data corresponding to one internal winning state in one gaming state and the number-of-drawing frame data corresponding to the reel stop status (and the stop operation position of the stopped reel) are uniquely determined. The stop control table created with reference to these is also unique for one internal winning state in one gaming state and the reel stop status (and the stop operation position of the stopped reel). Therefore, based on the same stop control table, that is, the same control pattern, when the gaming state, the internal winning state, and the reel stop status (and the stop operation position of the stopped reel) all have the same conditions. The reel stop control is performed.

  Further, in this embodiment, a value of 0 to 4 is determined as the number of sliding frames, and the reel can be stopped by drawing a maximum of 4 symbols after detecting the stop operation. In other words, the stop position of the symbol can be designated from a range of a maximum of 5 frames including the stop operation position where 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 table index, the address corresponding to the case where one of the winning combinations is won is drawn to the maximum in the range of four frames so that the winning combination is aligned with the winning line, and the winning combination is the winning line. The index data that identifies the data for creating the table with the number of sliding frames to be drawn so as not to be aligned is stored, and the corresponding address when winning is lost so that none of the roles match the winning line Index data for specifying data for creating a table in which the number of sliding frames to be drawn is determined is stored. For this reason, if you win any of the winning combinations, the maximum amount of the winning combination will be drawn in the range of 4 frames so that the winning combination will be aligned with the winning line, and the sliding piece will be drawn so that the winning combination will not align with the winning line A stop control table with a fixed number is created and reel stop control is performed. On the other hand, if none of the winning combinations are won, the number of sliding symbols that do not match any winning line is determined. A stop control table is created, and reel stop control is performed. As a result, when the stop operation is performed, if the symbols of the winning combination can be stopped on the winning line in the drawing range of up to 4 frames, the control is performed to align them and stop. The symbol of the winning combination will be controlled to be stopped in a drawing range of a maximum of 4 frames.

  Also, in the table index, if the special role and the small role are won at the same time (Big Bonus + 1 (1), Big Bonus + Bell, etc.), the selected special role will be aligned with the winning line 4 The number of sliding symbols is determined so that the maximum number of frames can be drawn in the range of frames, and the selected small role is the winning line for the stop operation position where the selected special role cannot be pulled into the winning line within the range of up to 4 frames. The index data for specifying the table creation data in which the number of sliding frames is determined so as to be drawn to the maximum within the range of 4 frames so as to be aligned with each other is stored, and reel stop control is performed. As a result, when the stop operation is performed, if the symbols of the special roles that have been elected within the draw range of up to 4 frames can be aligned and stopped on the winning line, the control is performed to align and stop them. If you can't draw a special role that you have won in the drawing range of up to 4 frames on the winning line, you can align the symbols of the small role that has been won in the drawing range of up to 4 frames on the winning line. If they can be stopped, control is performed to stop them together, and the symbol of the winning combination is controlled to be stopped in the drawing range of 4 frames. That is, in such a case, the control for aligning the special combination on the winning line is prioritized over the small combination, and the small combination can be won only when the special combination cannot be drawn into the winning line. When a special combination and a small combination can be drawn at the same time, only the special combination is drawn, and the small combination is not arranged on the winning line at the same time as the special combination.

  In addition, in the table index, the address corresponding to the case where a special combination and a replaying player are simultaneously elected (big bonus + replay, etc.) is drawn to the maximum in the range of 4 frames so that the replaying game is aligned with the winning line. In this way, index data for specifying data for creating a table with a determined number of sliding frames is stored, and reel stop control is performed. As a result, when a stop operation is performed, control is performed so that the symbols of the re-gamer are aligned and stopped on the winning line within a drawing range of up to four frames. As will be described later, “replay” which is a symbol constituting the re-gamer is arranged within 5 symbols, that is, within an interval of 4 frames for each of the reels 2L, 2C, 2R. Can be stopped at any position within the pull-in range, so if a special combination and a re-game player are elected at the same time, it will always be restarted regardless of the operation timing of the stop switches 8L, 8C, 8R by the player. Gamers will win along the winning line. That is, in such a case, the control for aligning the re-games on the winning line 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 arranged on the winning line simultaneously with the re-playing combination.

  In addition, in the table index, when a plurality of types of small roles with different payout numbers are simultaneously selected (bell + watermelon, bell + cherry, etc.), a small role with a large number of payouts among the selected small roles ( In this embodiment, when multiple types of small roles are elected at the same time, one of them will always be the bell with the maximum payout number. In this way, index data for specifying data for creating a table with a determined number of sliding frames is stored, and reel stop control is performed. As a result, when a stop operation is performed, control is performed such that the symbols of the small combination (bell) with a large number of payouts are aligned and stopped on the winning line within the maximum four-frame drawing range. As will be described later, “bell”, which is the symbol of the bell with the largest number of payouts, is arranged within 5 symbols, that is, within an interval of 4 frames for all of the reels 2L, 2C, 2R. Since it can always be stopped at any position within the frame drawing range, when multiple types of small roles with different payout numbers are won at the same time, regardless of the operation timing of the stop switches 8L, 8C, 8R by the player In addition, the bell will always win along the winning line. That is, in such a case, the control for aligning the bell on the winning line is prioritized over the small role other than the bell (the small role having a smaller number of payouts than the bell), and the bell always wins. In the case where a bell and a small role other than the bell can be withdrawn at the same time, only the bell is drawn, and other small roles are not aligned on the winning line at the same time as the bell.

  Here, as shown in FIG. 2, the “bell” and “replay” are arranged within 5 symbols, that is, within an interval of 4 frames, for all of the reels 2L, 2C, and 2R. It can be stopped at any position within the range. That is, when the winning flag for the bell and the replay is set, the winning combination can always be won regardless of the operation timing of the stop switches 8L, 8C, and 8R by the player.

  For “Red 7”, “White 7”, “Watermelon”, and “Cherry”, the reels 2L, 2C, and 2R are all arranged at intervals of 5 symbols or more, that is, at intervals exceeding 4 frames, particularly the left For the reel, there are places where “cherry” is arranged at intervals of 6 symbols or more, and for “orange”, there are locations where the reels 2C, 2R are arranged at intervals of 5 symbols or more, that is, at intervals exceeding 4 frames. Yes, these symbols cannot be aligned unless the stop operation is performed within the drawing range of 4 frames with respect to the winning line. For this reason, when drawing a bonus (1), big bonus (2), regular bonus, watermelon, cherry, 1 card (1), 1 card (2) with these symbols as a constituent symbol, the draw range of 4 frames If any reel is stopped at a timing other than the above, these winning combinations will not be aligned with any winning line and will be missed.

  In this embodiment, among the small and re-playing roles, the bell and replay can always be matched to the winning line regardless of the operation timing. As described above, the combination of watermelon, cherry, 1 The pieces (1) and (2) cannot be aligned unless a stop operation is performed at a timing when the constituent symbols are within a drawing range of four frames with respect to the winning line.

  Here, for the left reel, the stop operation position where “white 7” can be drawn into the winning line is area numbers 3 to 9, and the stop operation position where “red 7” can be drawn into the winning line is area numbers 15 to 9. 21. Stop operation positions where “watermelon” can be drawn into the winning line are area numbers 7 to 13, stop operation positions where “cherry” can be drawn into the winning line are area numbers 1 to 4, 11 to 17, 19 to 21. Of these stop operation positions, the region numbers 3 and 4 are stop operation positions where both “white 7” and “cherry” can be drawn, and the region numbers 7 to 9 are “white 7” and “ It becomes a stop operation position where both of “watermelon” can be drawn, and the area numbers 11 to 13 become stop operation positions where both “cherry” and “watermelon” can be drawn, and area numbers 15 to 17 and 19 21 to 21 are stop operation positions where both “Red 7” and “Cherry” can be drawn.

  In this way, there are stop operation positions at which “white 7” and “cherry”, “white 7” and “watermelon”, “cherry” and “watermelon”, and “red 7” and “cherry” can be aimed at the same time. However, there is no stop operation position that can simultaneously aim at three or more kinds of symbols among “Red 7”, “White 7”, “Watermelon”, and “Cherry”. That is, in the left reel, it is possible to aim at two types of symbols simultaneously among the watermelon, cherry, one (1), and one (2) symbols, but it is not possible to aim at three or more symbols simultaneously. It becomes possible.

  In this embodiment, as described above, the winning probabilities (including special roles and simultaneous winning probabilities) of watermelon, cherry, 1 (1), 1 (2) are 1 / 85.3 and 1/109. 2, 1 / 97.5, 1/182, so that the expected payout of medals when playing a game with these roles alone (the winning probability of the target role × the number of payouts of the target role), that is, these The number of medals that can be expected to be paid out per game when a game is aimed alone is approximately 0.0703 for watermelon, cherry, 1 (1), 1 (2), respectively. 0.0916, 0.0103, and 0.0054.

  And, for the left reel, the expected payout value of the medals when a game is performed simultaneously aiming at “white 7” and “cherry”, that is, one (1) and cherry, is when one (1) is aimed alone Is the sum of the expected payout value and the expected payout value when the cherry is aimed alone, and is 0.1018. “White 7” and “Watermelon” for the left reel, that is, the expected payout of medals when playing with one (1) and watermelon at the same time, “Watermelon” and “Cherry” for the left reel, that is, watermelon Expected medal payout when playing a game aiming at cherry at the same time, “red 7” and “cherry” for the left reel, that is, paying out a medal when playing a game aiming at one (2) and a cherry at the same time Expected values are approximately 0.0806, 0.1619, and 0.097, respectively.

  For this reason, in this embodiment, when the left reel is stopped for the first time, it is possible to simultaneously aim at two types of symbols among the watermelon, cherry, one (1), and one (2) constituent symbols. Among the operation positions, when the game is performed by stopping the left reel at the timing of the area numbers 11 to 13 at the stop operation position where the cherry and watermelon configuration symbols can be aimed at simultaneously, another stop operation is performed. This is advantageous to the player as compared with the case where the game is performed by performing the stop operation of the left reel at the position timing.

  Next, in the normal gaming state, stop control when the left reel is stopped in a state where all reels are still fluctuating, in particular, the timings of the area numbers 11 to 13 which are stop operation positions that are advantageous to the player described above. The stop control when the stop operation is performed will be described.

  FIG. 9 shows that when all the reels are still changing, if any combination is not won (losing), if replay is won (replay), if Bell is won (bell), When winning with watermelon (watermelon), when cherry is winning (cherry), when 1 (1) is won (the same applies when winning at the same time as a special role), 1 ( 2) is the case of winning (the same applies to the case of winning at the same time as a special role), or when any special role is winning alone (bonus), the timing of area numbers 11 to 13 respectively. It is a figure which shows the stop position which stops when stop operation is performed by.

  In the present embodiment, in the left reel stop control table that is applied when no combination is won (losing) and the left reel stop control table that is applied when replay is won (replay) In the case where the number of frames to be drawn in which the area number 10 is specified as the stop position with respect to the stop operation positions of the area numbers 11 to 13 is determined, and none of the winning combinations are won, and the replay is won When the stop operation of the left reel is performed at the timing of the region numbers 11 to 13, as shown in FIG. 10 is the stop position, and the display results of the region numbers 8, 9, 10 are stopped.

  Left reel stop control table applied when watermelon is won (watermelon), left reel stop control table applied when one (1) is won (1 (1)), In the left reel stop control table applied when the special combination is won alone (bonus), the lead-in frame in which the area number 9 is specified as the stop position with respect to the stop operation positions of the area numbers 11 to 13 In the case where the number is fixed and the watermelon, one piece (1), and the special role are elected, and the left reel is stopped at the timing of the area numbers 11 to 13, as shown in FIG. In addition, if the left reel is stopped at any timing among the region numbers 11 to 13, the region number 9 becomes the stop position, and the display results of the region numbers 7, 8, and 9 are stopped. At this time, if the watermelon is elected, the “watermelon is in a stopped state in the winning lines L2 and L4, and the“ watermelon ”is stopped in the drawing range of 4 frames with respect to these winning lines L2 and L4. If you stop the other reels at the timing that can be used, the combination of watermelons will be aligned on the winning line, but if one (1) is won or one of the special roles is won In such a case, since these combinations have already been missed, none of the combinations are arranged when all reels are stopped.

  In the stop control table for the left reel applied when the bell is elected (bell), among the stop operation positions of the area numbers 11 to 13, the area number 9 is specified as the stop position with respect to the area number 11. In the case where the number of frames to be drawn in which the area number 10 is specified as the stop position for the area numbers 12 and 13 is determined and the bell is elected, When the stop operation of the left reel is performed at the timing, the region number 9 or the region number 10 becomes the stop position, and the display result of the region numbers 7, 8, 9 or the display result of the region numbers 8, 9, 10 stops. At this time, the “bell” is stopped on the winning lines L2, L4 or the winning line L1, and the combination of the bells is always aligned with the winning line by stopping other reels.

  In the stop control table for the left reel applied when the cherry is won (cherry), the area number 11 is the stop position for the area numbers 11 and 12 among the stop operation positions of the area numbers 11 to 13. When the number of drawn frames to be specified is determined, and the number of drawn frames to which the region number 13 is specified as the stop position is determined with respect to the region number 13, and when the cherry is elected, the region numbers 11 to 13 When the stop operation of the left reel is performed at the timing, the region number 11 or the region number 13 becomes the stop position, and the display result of the region numbers 9, 10, 11 or the display result of the region numbers 11, 12, 13; Or the display result stops at the bottom. At this time, since “Cherry” has already stopped on the winning line, the combination of cherries is always aligned on the winning line by stopping other reels.

  In the stop control table for the left reel applied when one (2) is won (1 (2)), the area corresponding to the area number 11 among the stop operation positions of the area numbers 11 to 13 The number of drawn frames specified as number 7 is determined as the stop position, the number of drawn frames specified as area number 8 is determined as the stop position for area number 12, and the area number 9 is stopped for area number 13. When the number of frames to be drawn specified as the position is determined and one (2) is won, if the stop operation of the left reel is performed at the timing of the region numbers 11 to 13, the region number 7 and the region number 8 Alternatively, the area number 9 becomes the stop position, and the display results of the area numbers 5, 6, and 7, the display results of the area numbers 6, 7, and 8, or the display results of the area numbers 7, 8, and 9 are obtained. At this time, since one sheet (2) has already been missed, none of the roles are aligned when all reels are stopped.

  As described above, in this embodiment, when the left reel is set to the first stop (stopped first) and the stop operation is performed at the timings of the region numbers 11 to 13, the bell, the watermelon, one (1), 1 The display result of area numbers 7, 8, and 9 is stopped only when one (2) or any special role is won. In the case of losing, if replay is won The display results of area numbers 7, 8, and 9 are not stopped.

  Furthermore, when the bell is elected among these roles, the bell is always on the winning line when all the reels stop regardless of the operation timing of other reels, and the watermelon is elected In the other reels, the stop operation is aimed at “watermelon” and the watermelons are aligned on the winning line, while one (1), one (2) or any special role is won. In this case, regardless of the operation timing of the other reels, when all the reels are stopped, none of the winning combinations are aligned with the winning line.

  Therefore, if the left reel is set to the first stop and the stop operation is performed at the timings of the area numbers 11 to 13, and the display result of the area numbers 7, 8, and 9 is stopped, the special role is won. In the event that none of the roles are in line with the winning line, there is a chance that the player will win a special role or may win the special role at the same time (1 ) Or 1 (2), or you have missed a watermelon, which suggests that you are more likely to win a special role. That is, in this embodiment, when the left reel is set to the first stop and the stop operation is performed at the timings of the area numbers 11 to 13, the display results of the area numbers 7, 8, and 9 are stopped, and any role is played. The display mode that does not align with the winning line does not confirm the winning of the special role, but it is more likely than other display modes (except for the reach that indicates that the special role has been selected). It functions as an opportunity to show the effect.

  Further, in this embodiment, when the left reel is set to the first stop and the stop operation is performed at the timing of the area numbers 11 to 13, the area numbers 5 and 6 are only obtained when one (2) is elected.・ The display result of area number 6, 7, 8 is stopped. In other cases, the display result of area number 5, 6, 7 and area number 6, 7, 8 is not stopped. It has become. Further, in this case, regardless of the operation timing of the other reels, when all the reels are stopped, none of the winning combinations are aligned with the winning line.

  Therefore, when the left reel is set to the first stop and the stop operation is performed at the timing of the area numbers 11 to 13, the display results of the area numbers 5, 6, 7 and the area numbers 6, 7, 8 are stopped. Since it is confirmed that one (2) who is more likely to be elected at the same time as a special role than one (1) is won, it will be won simultaneously than one (2). If you are elected to the one (1) that is unlikely to be, or if the display result of the area number 7, 8, 9 that can appear even when the watermelon is dropped, will be elected to the special role It is suggested that there is a high possibility that That is, in this embodiment, when the left reel is set to the first stop and the stop operation is performed at the timing of the area numbers 11 to 13, the display results of the area numbers 5, 6, 7 and the area numbers 6, 7, 8 are displayed. Stopped display mode functions as a chance chance that the display results of area numbers 7, 8, and 9 are stopped and that there is a higher possibility that a special role is won more than the display mode in which none of the roles match the winning line It is supposed to be.

  Further, in this embodiment, when a non-left reel is set as the first stop, and then the left reel is stopped at the timing of the area numbers 11 to 13, the winning combination is aligned with the winning line. With the exception of 1) (1), 1 (2), if any special role has been won, or if the watermelon has been won and the reel has already stopped, ”Is not stopped, that is, when the watermelon is dropped, the display results of the region numbers 7, 8, and 9 are stopped. In other cases, the display results of the region numbers 7, 8, and 9 are not stopped. It has become.

  For this reason, if the other reels are set to the first stop, and the stop operation of the left reel is performed at the timing of the area numbers 11 to 13, the display result of the area numbers 7, 8, and 9 is stopped. Either winning a role, winning one (1) or one (2) with the possibility of winning simultaneously with a special role, or dropping a watermelon on a reel that has already been stopped. It is suggested that there is a high possibility that the role is won. That is, in the present embodiment, when the first reel is stopped except for the left reel, and the left reel is stopped at the timing of the area numbers 11 to 13, the display result of the display results of the area numbers 7, 8, and 9 is stopped. It has come to function as a chance eye.

  In this embodiment, the CPU 41a continues to rotate the reels for which the stop operation has not yet been detected until the operation of the stop switches 8L, 8C, 8R is detected after the rotation of the reels 2L, 2C, 2R is started. Then, 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, it is preferable to derive a display result that does not constitute any combination even if any combination is won.

  The CPU 41a according to the present embodiment performs an abnormal winning determination that determines whether or not a combination that is not permitted in the game is aligned on the winning line when all the reels are stopped. When a combination that has not been won in the internal lottery is arranged, and when a special combination and a general combination are prepared at the same time, it is determined that the prize is abnormal. If it is determined that the prize is abnormal, it is controlled to an abnormal prize error state to disable the progress of the game. The abnormal winning error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated as in the case of the disconnection error error or the RAM error error described above, and the CPU 41a in the area of the RAM 41c. All areas except for the area in use are initialized, cannot be restored to the original state, and are not canceled until a new set value is set in the setting change mode described above.

  Next, initialization of the RAM 41c of the main control unit 41 will be described. The storage area of the RAM 41c of the main control unit 41 is divided into an important work, a general work, a special work, a set value work, a non-saved work, an unused area, and a stack area.

  The important work is a work that stores data that is inconvenient to be initialized at the end of the big bonus, such as various display devices and LED display data, input / output data of the I / O port 41d, and a game time counter. The general work is a work in which data that can be initialized at the end of the big bonus, such as a stop control table, a stop symbol, the number of medals paid out, and the total number of medals paid out in the big bonus, are stored. The special work is a work that stores data to be initialized only before the start of setting, such as data for transmitting a command to the effect control board 90 and various software random numbers. The set value work is a work in which a set value used when performing a lottery in the internal lottery process is stored. After initializing 0 before setting is started (before shifting to the setting change mode), 1 is stored. The set value that is corrected and newly set at the end of the setting (when the setting change mode is ended) is stored. The unsaved work is a work that holds the state of various switches, and a value is always set regardless of whether or not the data in the RAM 41c is destroyed at the time of activation. The unused area is an unused area in the storage area of the RAM 41c, and is initialized if any one of a plurality of initialization conditions described later is satisfied. The stack area is an area in which data saved from the register of the CPU 41a is stored, and the unused stack area is satisfied by any one of a plurality of initialization conditions to be described later, like the unused area. However, the used stack area is not initialized because the program continues.

  In this embodiment, the CPU 41a of the main control unit 41 terminates the big bonus before the start of setting (before the transition to the setting change mode) and when an unrecoverable error (disconnection error, RAM error, abnormal winning error) occurs. When the data in the RAM 41c is not destroyed at the time of startup, when four initialization conditions at the end of one game are satisfied, four types of initials with different areas initialized according to each initialization condition To do.

  Initialization 1 is a state in which the setting key switch 37 is in an ON state at the time of start-up, and when shifting to the setting change mode, initialization performed before that and an error that cannot be recovered (disconnection abnormality error, RAM abnormality error, In the initialization 1, all the areas (including the unused area and the unused stack area) other than the used stack area are initialized in the storage area of the RAM 41c. The Initialization 2 is initialization performed at the end of the big bonus. In initialization 2, the general work, the unused area, and the unused stack area are initialized in the storage area of the RAM 41c. Initialization 3 is initialization that is performed when the setting key switch 37 is in an OFF state at the time of startup and the data in the RAM 41c is not destroyed. The used stack area is initialized. Initialization 4 is initialization performed at the end of one game. In initialization 4, an unused area and an unused stack area in the storage area of the RAM 41c are initialized.

  Next, commands that the CPU 41a of the main control unit 41 transmits to the effect control board 90 will be described.

  In the present embodiment, the CPU 41a of the main control unit 41 makes a BET command, an internal winning command, a reel rotation start command, a reel stop command, a winning determination command, a payout start command, a payout end command, a gaming state to the effect control board 90. A plurality of types of commands including a command, a standby command, a stop command, an error command, an initialization command, a setting end command, and a power-on command are transmitted.

  The BET command is a command that can specify the number of medals inserted, that is, the number of medals used to set the bet number. Sent when

  The internal winning command is a command that can specify the winning status of the internal winning flag and the type of the internal winning flag established, and is transmitted when the start switch 7 is operated to start the game.

  The reel rotation start command is a command for notifying the start of reel rotation, and is transmitted when rotation of the reels 2L, 2C, and 2R is started.

  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. And is transmitted each time stop control of each reel is performed.

  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 at the time of winning, and is transmitted after all the reels are stopped and the winning determination is performed.

  The payout start command is a command for notifying the start of payout of medals, and is transmitted when the payout of medals is started by paying out a prize or credit (including medals used for setting the number of bets). The payout end command is a command for notifying the end of payout of medals, and is transmitted when the payout of medals by winning and winning a credit is completed.

  The gaming state command is a command that can specify the gaming state of the next game (whether it is a normal gaming state, a big bonus, a regular bonus, etc.), and is transmitted at the end of the game.

  The stand-by command is a command indicating a transition to a stand-by state, and when a certain time (30 seconds in the present embodiment) elapses without a bet amount being set after one game is over, or when a credit is entered. Sent when transitioning to the standby state with the settlement of. In the present embodiment, when the bet number is set to 1, even if a certain time elapses after the end of one game, the standby command is not transmitted.

  The stop command is a command indicating the occurrence or release of the stop state, and after the end of the BB, the stop command indicating the occurrence of the stop state is transmitted when the ending effect waiting time has elapsed, and the reset operation is performed. When the stop state is released, a stop command indicating the release of the stop state is transmitted.

  An error command is a command that indicates the occurrence or release of an error state. When an error is determined and controlled to the error state, an error command that indicates the occurrence of the error state is sent, and a reset operation is performed to release the error state. At that time, an error command indicating the cancellation of the error state is transmitted.

  The initialization command is a command indicating that the gaming state has been initialized and the start of the setting change mode, and is transmitted when the RAM 41c is initialized and shifts to the setting change mode.

  The setting end command is a command indicating the end of the setting change mode, and is transmitted at the end of setting, that is, at the end of the setting change mode.

  The power-on command is a command that indicates whether or not one of the special roles has been won at power-on, and if it can be restored to the state before the power interruption at startup, it returns to the state before the power interruption. Sent at a time before

  Each of these commands is generated in an activation process and a game process described later, temporarily stored in a command queue provided in a special work in the RAM 41c, and transmitted in the timer interrupt process (main) described above.

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

  When the CPU 91a of the sub control unit 91 receives a command transmitted by the CPU 41a of the main control unit 41, the CPU 91a refers to the control pattern table stored in the ROM 91b, and displays the liquid crystal display based on the control content registered in the control pattern table. The various effect devices such as the device 51, the effect LED 52, the speakers 53 and 54, and the reel LED 55 are controlled.

  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. The control patterns of these effect devices are registered, and when the CPU 91a receives a command, the CPU 91a receives among the control patterns registered corresponding to the effect patterns set in the RAM 91c in the game of the control pattern table. The control device corresponding to the type of the command is referred to, and the rendering device is controlled based on the control pattern. Thereby, the production according to the production pattern and the progress of the game is executed.

  If the CPU 91a receives a new command during the execution of an effect triggered by the reception of a certain command, the CPU 91a stops the effect based on the control pattern being executed, and performs control corresponding to the newly received command. An effect based on the pattern is executed. In other words, even when the effect has not been completed until the end, when a new command is received, the effect that has been executed is canceled and the effect based on the new 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. When the CPU 91a receives the internal winning command, the CPU 91a is registered in the effect table according to the result of the internal lottery indicated by the internal winning command. The selected selection pattern is selected from a plurality of types of production patterns according to the selection rate, and the selected production pattern is set in the RAM 91c as the production pattern of the game.

  The control pattern table also includes specific commands (a winning determination command indicating the occurrence of winning, a payout start command, a payout end, a gaming state command indicating the end of the big bonus, a standby command, a stop command, an error command, an initialization command. , A setting end command, a power-on command indicating that the special role is won, etc.) are stored, and when the CPU 91a receives these specific commands, the CPU 91a Regardless of the effect pattern set in, a specific control pattern corresponding to the command is referred to, and the effect device is controlled based on the control pattern.

  When a winning determination command indicating the occurrence of a winning is received, a winning effect pattern for executing a winning effect according to the type of winning is referred to as a control pattern. In particular, when a winning determination command indicating the occurrence of a big bonus winning is received, a BB winning pattern for executing a BB winning effect peculiar to the big bonus winning is referred to as a control pattern.

  When a payout start command is received, a payout pattern for outputting payout sound effects is referred to as a control pattern. Further, when a payout end command is received during the output of the payout sound effect, the output of the payout sound effect is stopped. When a payout start command is received, unlike the other commands, the effect that is being executed is not executed and the effect corresponding to the received command is not executed. Sound effects are output. That is, the other effects and the effects accompanying the payout are executed in parallel.

  When a gaming state command indicating the end of the big bonus is received, an ending pattern for executing an ending effect indicating the end of the big bonus is referred to as a control pattern.

  When a standby command is received, a standby pattern for executing a standby effect as a demonstration effect is referred to as a control pattern. In addition, when a bonus medium effect accompanying a big bonus or a regular bonus is being executed, the execution of the standby effect is prohibited. It is not referred to as a control pattern, and no standby effect is executed.

  When a stop command indicating the occurrence of a stop state is received, a stop notification pattern for notifying that the stop state is in effect is referred to as a control pattern. When a stop command indicating release of the stop state is received, the above-described standby pattern is referred to as a control pattern. That is, when the stop state is released, the standby effect is executed.

  When an error command indicating the occurrence of an error state is received, an error notification pattern for notifying the fact of the error state and its type is referred to as a control pattern. When an error command indicating the cancellation of the error state is received, the control pattern that was being executed when the error occurred is referred to. That is, the production at the time of error occurrence is executed from the beginning.

  When the initialization command is received, a setting notification pattern for notifying that the setting is being changed is referred to. When the setting end command is received, the above-described standby pattern is referred to as a control pattern. In other words, when an initialization command is received, a notification during setting change is executed, and thereafter, when a setting end command is received, a standby effect is executed.

  When a power-on command indicating that a special role is won is received, a special role notification pattern for notifying that the special role has been won is referred to. That is, when a power-on command indicating that the special role is won is received, a notification effect for notifying that the special role is won is executed. Note that the notification effect for notifying the winning of the special combination is once executed until it receives a winning determination command indicating that the special combination has won.

  The CPU 91a of the sub-control unit 91 performs RAM parity adjustment so that the RAM parity based on the data stored in all areas of the RAM 91c becomes 0 each time the timer interrupt process (sub) that is periodically executed is executed. Data is calculated and stored in the RAM 91c.

  Then, the CPU 91a calculates the RAM parity based on the data stored in all the areas of the RAM 91c at the time of activation, and is based on the data stored in the RAM 91c on the condition that the RAM parity is 0. It is designed to return to the production state before the interruption. Specifically, the control pattern executed last is referred to and control based on the control pattern is executed. As a result, an effect based on the control pattern executed before power interruption is executed from the beginning. Further, when the RAM parity calculated based on the data stored in all areas of the RAM 91c at the time of startup is not 0 (in the case of 1), it is determined that the RAM is abnormal, and all areas of the RAM 91c are initialized. It has become.

  In addition, the CPU 91a receives an initialization command or a power-on command before actually starting the production regardless of whether or not the production state before power interruption can be restored based on the data stored in the RAM 91c at the time of activation. Wait until either is received. When the initialization command is received in this state, the data in the RAM 91c is cleared. In addition, when a power-on command indicating that the special role is elected is received in this state, a notification effect indicating that the special role is elected is executed. If it is possible to return to the effect state before the power interruption, it returns, and if it cannot be recovered, the standby effect is executed. Also, in the state of waiting for receiving the initialization command or the power-on command, the execution of the timer interrupt process that executes the presentation based on the reception of the command is not permitted, and even when other commands are received, An effect based on the command is not performed, and no effect is performed until the initialization command or the power-on command is received after the startup and the execution of the timer interrupt process is permitted.

  Further, when receiving the internal winning command, the CPU 91a of the sub-control unit 91 stores the winning situation of the internal winning flag specified from the internal winning command and the type of the established internal winning flag in the RAM 91c, and then the internal winning command. Holds the winning command until it is updated. When the reel stop command is received, the stop reel specified from the reel stop command, the area number of the stop operation position of the corresponding reel, and the area number of the stop position of the corresponding reel are stored in the RAM 91c, and then the reel rotation start command Is held, that is, until the rotation of the reel in the next game is started, and erased as the rotation starts. When a winning determination command is received, the presence / absence of a winning specified from the winning determination command, the type of winning, and the number of medals paid out at the time of winning are stored in the RAM 91c until the winning determination command is received and updated. Hold. When the gaming state command is received, the gaming state of the next game specified from the gaming state command (normal gaming state, big bonus, regular bonus, etc.) is stored in the RAM 91c, Next, the incoming game state command is received and held until updated.

  Further, the CPU 91a of the sub-control unit 91, when a predetermined time (60 seconds in this embodiment) elapses without all the stop operations of the reels 2L, 2C, and 2R being started after the reel starts rotating, that is, the reel After acquiring the rotation start command, when a predetermined time (60 seconds in this embodiment) has passed without acquiring the reel stop command for all the reels, a promotion notification for prompting the reel stop operation is performed.

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

  When the reset signal is input from the reset circuit 49, the CPU 41a performs a startup process shown in the flowchart of FIG. Since the reset signal is a signal output when the power is turned on and when the operation of the main control unit 41 is stagnant, the activation process is performed when the CPU 41a is activated when the power is turned on and when the CPU 41a is activated due to a malfunction. This is a process to be performed.

  In the start-up process, first, the built-in device and peripheral IC (excluding disconnection monitoring IC 50), interrupt mode, stack pointer, etc. are initialized (Sa1), then the voltage drop signal detection data is acquired from the input port, and the voltage drop It is determined whether or not a signal is input, that is, whether or not the voltage is stable (Sa2), and when a voltage drop signal is input, other than whether or not a voltage drop signal is input Shifts to a loop process that does not perform any process.

  If it is determined in step Sa2 that the voltage drop signal is not input, the values of the I register and IY register are initialized (Sa3), and the states of the stop switch 36 and the automatic settlement switch 29 are acquired. Validity / invalidity of the stop function and automatic settlement function is set in a specific register of the CPU 41a (Sa4). 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, access to the RAM 41c is permitted (Sa5), and it is determined whether or not the setting key switch 37 is in an ON state (Sa6). If the setting key switch 37 is not in the ON state at step Sa6, the storage state of the disconnection flag is acquired from the disconnection monitoring IC 50 (Sa7), and it is determined whether the disconnection flag is stored (Sa8). If the electrical connection state between the game control board 40 and the inserted medal sensor 31 and the electrical connection state between the game control board 40 and the effect control board 90 are not released during a power failure, the disconnection flag is If the disconnection flag is stored, the state of electrical connection between the game control board 40 and the inserted medal sensor 31 or the game control board 40 and the effect control board 90 is not stored. Since the electrical connection state between and is released, an error code indicating a disconnection abnormality is set in the register (Sa9), and the process proceeds to the error processing shown in FIG.

  If the disconnection flag is not stored in step Sa8, the RAM parities of all the storage areas (including the unused area and the unused stack area) of the RAM 41c are calculated (Sa10), and whether the RAM parity is 0 or not. Is determined (Sa11). If the interruption interrupt process (main) is normally performed, the RAM parity should be 0. If the RAM parity is not 0 in the step of Sa11, the data stored in the RAM 41c is not normal. Therefore, an error code indicating a RAM abnormality is set in the register (Sa13), and the process proceeds to the error process shown in FIG.

  If the RAM parity is 0 in step Sa11, it is further determined whether or not the destructive diagnosis data is normal (Sa12). If power interruption interrupt processing (main) is performed normally, the data for destruction diagnosis should be set. If the data for destruction diagnosis is not normal in step Sa12 (data for destruction diagnosis is power interruption) Since the data in the RAM 41c is not normal also in cases other than 5A (H) stored at the time), an error code indicating RAM abnormality is set in the register (Sa13), and the process proceeds to the error processing shown in FIG.

  In the error processing, as shown in FIG. 11, the current display state of the game auxiliary display 12 is saved in the stack (Sb1), and the error code stored in the register is displayed on the game auxiliary display 12 (Sb2). .

  Next, the error code stored in the register is checked, and it is determined whether or not the error code is an error code indicating a disconnection error, a RAM error, or an abnormal winning error (Sb3). In the case of an error code indicating an abnormal error or an abnormal winning error, after performing initialization 1 for initializing all the storage areas in the storage area of the RAM 41c except the used stack area (Sb4), The process proceeds to a loop process that does not perform any process.

  If it is determined in step Sb3 that the error code is not an error other than a disconnection error, a RAM error, and an abnormal winning error, it is determined whether an operation of the reset / setting switch 38 is detected. (Sb5) If the operation of the reset / setting switch 38 is not detected, it is further determined whether or not the operation of the reset switch 23 is detected (Sb6). If the operation of the reset switch 23 is not detected, Return to step Sb5. That is, the game waits in a state where the progress of the game is impossible until the operation of the reset / setting switch 38 or the reset switch 23 is detected.

  When the operation of the reset / setting switch 38 is detected in the step Sb5 or when the operation of the reset switch 23 is detected in the step Sb6, the error code stored in the register is cleared (Sb7 ), The display state of the game auxiliary display 12 is returned to the display state saved in the stack in the step Sb1 (Sb8), and the process returns to the original process.

  As described above, in the error processing, if the error processing is other than the disconnection abnormality error, the RAM abnormality error, and the abnormal winning error, the error state can be canceled by operating the reset / setting switch 38 or the reset switch 23. If the error processing is due to a disconnection error, a RAM error, or an abnormal winning error, initialization 1 is performed to initialize all the storage areas of the RAM 41c except the stack area in use. When the reset / setting switch 38 or the reset switch 23 is operated, the error state is canceled and the original state is not restored.

  Returning to FIG. 10, when it is determined in the step Sa12 that the data for failure diagnosis is normal, the data in the RAM 41c is normal, so the unsaved work, the unused area, and the unused stack area in the RAM 41c are initialized. After performing initialization 3 (Sa14), the destruction diagnosis data is cleared (Sa15). Next, it is determined whether any special role is won in the state before the power interruption (Sa16). If any special role is elected in the state before the power interruption, A power-on command indicating winning is set (Sa17), and the process proceeds to step Sa19. If no special role is won in the state before power interruption, a power-on command indicating non-winning special role is set. (Sa18), the process proceeds to step Sa19.

  In step Sa19, each register is restored to the state before power interruption, that is, stored in the stack, interrupt is permitted (Sa20), and the process executed last before power interruption is returned to. When interrupt is permitted in step Sa20, timer interrupt processing is periodically executed, and accordingly, the power-on command set in step Sa17 or Sa18 is sent to sub-control unit 91. Sent.

  If the setting key switch 37 is in the ON state in the step of Sa6, after executing initialization 1 that initializes all the storage areas in the storage area of the RAM 41c except the used stack area (Sa21), The value stored in the set value work (0 at this time) is corrected to 1 (Sa22). Next, after setting the initialization command (Sa23), the interruption is permitted (Sa24), and the setting change process shown in FIG. 12, ie, the setting change mode is entered (Sa25). When the interrupt is permitted in the step Sa24, the timer interrupt process is periodically executed, and the initialization command set in the step Sa23 is transmitted to the sub-control unit 91 accordingly. . After the setting change process in step Sa25 is completed, a setting end command is set (Sa26), and the process proceeds to the game process. The initialization command set in step Sa26 is transmitted to the sub-control unit 91 in the subsequent timer interrupt process.

  In the setting change process, as shown in FIG. 12, the setting value stored in the setting value work of the RAM 41c (the value of the setting value work is corrected to 1 before shifting to the setting changing process. Is read out (Sc1).

  Thereafter, the operation waits for detection of the operation of the reset / setting switch 38 and the start switch 7 (Sc2, Sc3). When the operation of the reset / setting switch 38 is detected in the step of Sc2, the setting value read in the step of Sc1. 1 is added (Sc4), and it is determined whether or not the set value after addition is 7, that is, whether or not the settable range is exceeded (Sc5). If the set value after addition is not 7, After returning to the detection waiting state for the operation of the reset / setting switch 38 and the start switch 7 in the steps Sc2 and Sc3 again, if the setting value after addition is 7 in the step Sc5, the setting value is corrected to 1 (Sc6). ), The process returns to the detection waiting state for the operation of the reset / setting switch 38 and the start switch 7 in the steps Sc2 and Sc3.

  When the operation of the start switch 7 is detected in the step of Sc3, the changed set value selected at that time is stored in the set value work of the RAM 41c and the set value is confirmed (Sc7). Wait until the setting key switch 37 is turned off (Sc8). If it is determined in step Sc8 that the setting key switch 37 is OFF, the flow returns to the flowchart of FIG. 10 and the game process is started.

  As described above, in the starting process, when the setting key switch 37 is not in the ON state, it is determined whether or not a disconnection flag is stored. If the disconnection flag is stored, the process proceeds to an error process. Further, it is determined whether or not the data stored in the RAM 41c is normal by determining whether or not the RAM parity is 0 and whether or not the data for destructive diagnosis is normal, and the data in the RAM 41c is normal. If not, the process proceeds to error processing. In the error processing due to the disconnection error error or the RAM error error, the error code indicating the disconnection error error or the RAM error error is displayed on the game auxiliary display 12 and then initialized so that it cannot return to the state before the power interruption. To initialize the RAM 41c and shift to a loop process in which no process is performed, so that the progress of the game is disabled. If the data in the RAM 41c is not normal, the interrupt is not permitted. Therefore, once the process proceeds to error processing due to a disconnection error or RAM error, the setting key switch 37 is activated and the interrupt is interrupted. Until interruption is permitted, the interruption interruption process (main) is not performed even if the interruption occurs. That is, the RAM adjustment data is not calculated and stored so that the RAM parity is newly set to 0 in the power interruption interrupt process (main), and the destruction diagnosis data is not newly set. Even if the CPU 41a is restarted, the game cannot be restarted even if the CPU 41a is restarted, except when the setting key switch 37 is started in the ON state.

  Once the process proceeds to error processing due to disconnection error or RAM error, the setting key switch 37 is activated and all the areas except the used stack area of the RAM 41c are initialized, and then the setting change process is performed. Until the setting value is newly selected and set by operating the reset / setting switch 38, the game cannot be progressed. In other words, in the state where the error processing due to the RAM abnormality error is started, the state in which the game cannot be progressed is canceled and the game is resumed on the condition that a new set value is selected and set by operating the reset / setting switch 38. It becomes possible to make it.

  FIG. 13 is a flowchart showing the control contents of the game process executed by the CPU 41a.

  In the game process, a BET process (Sd1), an internal lottery process (Sd2), a reel rotation process (Sd3), a winning determination process (Sd4), a payout process (Sd5), and a game end process (Sd6) are sequentially executed. When the end-time process ends, the process returns to the BET process again.

  In the BET process in the step of Sd1, the process waits in a state where the bet number can be set, sets a predetermined number of bets according to the gaming state, and executes a process of determining the bet number when the start switch 7 is operated. To do.

  In the internal lottery process in step Sd2, a random number for internal lottery is extracted simultaneously with the start of the game by the detection of the start switch 7 in step Sd1, and the winning of each above-described combination is permitted based on the extracted random number value. Process to determine whether or not. In this internal lottery process, a winning flag is set in the RAM 41c based on the respective lottery results.

  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.

  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. In the winning determination process, an abnormal winning determination process is performed to determine whether or not an abnormal winning has occurred, such as winning a winning combination or winning a special combination and a general combination at the same time.

  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.

  FIG. 14 is a flowchart showing the control contents of the internal lottery process executed by the CPU 41a in step Sd2.

  In the internal lottery process of the present embodiment, first, a prescribed number that is a predetermined number of medals inserted in accordance with the game state of the game is read (Se1), and the process proceeds to Step Se2. The prescribed number is 3 in the normal gaming state and 1 in the regular bonus gaming state.

  In the step of Se2, it is determined whether or not the number of inserted medals, that is, the value of the BET counter is the specified number read in the step of Se1, and if the inserted number of medals is the specified number, the process proceeds to the step of Se3. If the input number is not the specified number, the process proceeds to Step Se4.

  In the step of Se3, it is determined whether or not the set value stored in the set value work of the RAM 41c is in the range of 1 to 6, that is, whether or not the set value stored in the set value work is an appropriate value. If the set value is in the range of 1 to 6, the process proceeds to Step Se5, and if not, the process proceeds to Step Se4.

  In the step of Se4, since it is determined that the data stored in the RAM 41c is not normal, an error code indicating the RAM abnormality is stored in the register, and the process proceeds to the error processing shown in FIG.

  In the step of Se5, a random number acquisition process for acquiring a random number used in the game is performed, and the process proceeds to the step of Se6. In the random number acquisition process, a sampling command is output to the sampling circuit 43, the random number generated by the random number generation circuit 42 is latched, and the latched random number value is input from the I / O port 41d and extracted. A predetermined logical operation is performed on the extracted random number, and the result is obtained as a random number.

  In the step of Se6, the state number (any one of 0 to 2) is stored in the RAM 41c according to the game state of the game, and the process proceeds to the step of Se7. In the step of Se7, in the gaming state indicated by the state number, the hand number to be drawn first is stored in the RAM 41c, and the process proceeds to the step of Se8. In the step of Se7, when the state number is 0, that is, when no special combination is carried over in the normal gaming state, 0 (big bonus (1)) is first set as the combination number to be drawn. When the state number is 1, that is, when any special combination is carried over in the normal gaming state, 9 (replay) is first set as the combination number to be drawn, and the state number is 2. That is, in the case of a regular bonus, 14 (bell) is first set as the winning number to be drawn.

  In the step of Se8, it is confirmed whether or not the state number is 2, that is, whether or not the regular bonus is being performed. If the state number is 2, that is, if the regular bonus is being performed, the processing proceeds to the step of Se10. . If the status number is not 2, the process proceeds to step Se9.

  In the step of Se9, it is confirmed whether or not the role number as the lottery target is 15, that is, whether or not all the lotteries subject to the lottery are finished in the gaming state other than the regular bonus, and the role number is 15 If so, the process proceeds to Se11. If not 15, the process proceeds to step Se10.

  In the step of Se10, it is confirmed whether or not the role number as the lottery target is 19, that is, whether or not the lottery for all the lottery targets in the regular bonus has ended. Advances to the step of Se11. If not 19, the process proceeds to step Se12.

  In the step of Se11, the general combination storing work in which the general combination winning flag is stored in the RAM 41c is cleared, the internal lottery process is terminated, and the process returns to the flowchart shown in FIG.

  In the step of Se12, it is checked whether or not the common flag registered in the role-specific table is 1 in association with the processing target number, and if it is 1, the process proceeds to the step of Se13. Advances to step Se14.

  In step Se13, the address of the storage area for the number of determination values in the ROM 41b registered in the role-specific table in association with the role number to be processed is read. Then, the number of judgment values stored at this address is acquired, and the process proceeds to Step Se15.

  In the step of Se14, first, the set value stored in the RAM 41c is read, and further, the number of determination values of the ROM 41b registered in the role-specific table is associated with the processing-target role number and the read set value. Read the address of the area. Then, the number of judgment values stored at this address is acquired, and the process proceeds to Step Se15.

  In the step of Se15, the number of determination values acquired in the step of Se13 or Se14 is added to the random number value for internal lottery, and the result of the addition is set as a new random number value. The process proceeds to the step of Se16, and the number of determination values is determined by internal lottery. It is determined whether an overflow has occurred when added to the random number value. The occurrence of an overflow indicates that the winning combination corresponding to the processing target winning number has been won. If an overflow occurs, the process proceeds to step Se18. If no overflow has occurred, the process proceeds to step Se17.

  In step Se17, 1 is added to the role number to be processed, and the process returns to step Se8.

  In the step of Se18, it is confirmed whether or not the combination number is 0 to 8, that is, a combination number indicating a special combination or a combination including a special combination. If the combination number is 0 to 8, the step of Se19 is performed. If the combination number is not 0 to 8, the process proceeds to Step Se20.

  In the Se19 step, the special combination winning flag corresponding to the combination number to be processed is set in the special combination storing work in which the special combination winning flag is stored in the RAM 41c. In the Se20 step, the general combination storing work in the RAM 41c. In addition, the winning flag of the general combination corresponding to the combination number to be processed is set, the internal lottery process is terminated, and the process returns to the flowchart shown in FIG. In the Se20 step, when the combination number is 0 to 2, since the general combination is not won, the general combination storing work in the RAM 41c is cleared in this case.

  FIG. 15 is a flowchart showing the control contents of the reel rotation process executed by the CPU 41a in step Sd3.

  In the reel rotation process, first, it is determined whether or not a wait time (about 4.1 seconds in this embodiment) has elapsed since the reel rotation start time of the previous game (Sf1), and the wait time must have elapsed. For example, it waits until the wait time elapses.

  If the wait time has elapsed in step Sf1, a new wait time is set (Sf2).

  Next, the setting at the time of starting the rotation of the reel motor is performed, and the rotation of the reel is started (Sf3). Then, referring to the table index, the table creation data is specified, and the stop control table corresponding to the game state of the game, the winning combination status of the game, and the stop status of other reels based on the specified table creation data Is created for each reel that is rotating (Sf4), and setting is made when stop preparation is completed (Sf5). As a result, the stop operation can be enabled, and then the stop operation becomes effective when the constant speed rotation of the reel is detected in the timer interruption process (main), which will be described later, during the origin passage process. It becomes.

  Next, it is determined whether or not any of the stop switches 8L, 8C, and 8R has been detected (Sf6). If any of the stop switches has not been detected, a reel rotation error (over a certain period of time). Then, it is determined whether or not an error determined when the reel reference position is not detected by the reel sensor 33 (Sf7). If no reel rotation error has occurred, an insertion error (medal insertion) is further performed. Whether or not a medal insertion was detected outside the permitted period, and whether or not a payout error (medal payout was detected outside the medal payout period) Error) is determined (Sf8, Sf9), and any error occurs in steps Sf7 to Sf9. If it is not determined, the flow returns to step Sf6.

  If it is determined in Sf8 that the insertion error has occurred, or if a payout error is determined in Sf9, an error code indicating the insertion / discharge error during reel rotation is set in the register (Sf10). ), The process proceeds to the error process shown in FIG. 11 (Sf11). When the error is released, the process returns to step Sf6 again.

  If it is determined in step Sf7 that a reel rotation error has occurred, an error code indicating a reel rotation error is set in the register (Sf12), and the process proceeds to error processing shown in FIG. 11 (Sf13). Along with this, the rotation of the reels is also temporarily stopped. When the error is released, the process returns to the step Sf3 again, and the reel rotation is resumed.

  If any stop switch operation is detected in step Sf6, the number of steps from the reel reference position at that time in the reel motor corresponding to the stop switch (the number of steps to be the stop operation position) is calculated. After obtaining and setting the work corresponding to the stop reel (Sf14), the process waits until the rotation of the reel corresponding to the stop operation stops (Sf15).

  Then, when the rotation of the reel corresponding to the stop operation stops, the detection of the operation of the stop switch corresponding to the reel is invalidated, and then it is determined whether or not all the reels are stopped (Sf16). If not stopped, the process returns to the step of Sf4. If all the reels are stopped, the reel rotation process is terminated and the process returns to the flowchart of FIG.

  FIGS. 16 and 17 are flowcharts showing the control contents of the timer interrupt process (main) executed by the CPU 41a in response to the occurrence of the interrupt 3, that is, interrupting the start process or the game process at intervals of 0.56 ms. .

  In the timer interrupt process (main), interrupts are first prohibited (Si1). That is, the execution of another interrupt process during the execution of the timer interrupt process (main) is prohibited. Then, the register in use is saved in the stack area (Si2).

  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 (Si3). In the step of Si3, 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 referred to determine whether it is 2 or 3, that is, timer interrupt 3 or timer interrupt 4 (Si4). 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 is executed to output the phase signal data changed in the Si8 motor step process described later and the phase signal data changed in the Si23 final stop process described later (Si5).

  Next, it is determined whether or not it is 1 (ie, timer interrupt 2) by referring to the minute counter value (Si6). If it is not timer interrupt 2 (ie, timer interrupt 1), the reel motor Reel start processing (Si7) for controlling the step time interval when starting 32L, 32C, 32R, motor step processing (Si8) for changing phase signal data of the reel motors 32L, 32C, 32R, reel motors 32L, 32C After the stop of 32R, the motor phase signal standby processing (Si9) for changing the phase signal to one-phase excitation after a predetermined time has been sequentially executed, and then the register saved in the stack area in Si2 is restored (Si20). The interrupt prohibited in the step is permitted (Si21), and the process returns to the state before the interrupt.

  Further, in the case of timer interrupt 2 in the step of Si6, LED dynamic display processing (Si10) for dynamically lighting various indicators, output processing of control signals and the like for outputting data such as lighting signals of various LEDs to an output port (Si11), random number update processing for updating various software random numbers (Si12), time counter update processing for updating various time counters (Si13), command transmission for transmitting commands stored in the command queue to the effect control board 90 After executing the process (Si14) and the external output signal update process (Si15) for updating the external output signal in sequence, the register saved in the stack area in Si2 is restored (Si20), and the interrupts prohibited in the Si1 step are permitted. (Si21), and the process returns to the state before the interruption.

  If it is timer interrupt 3 or timer interrupt 4 in the Si4 step, it is further determined by referring to the counter value for wake-up 3 whether it is 3, ie, timer interrupt 4 (Si16). If it is not interrupt 4, that is, timer interrupt 3, port input processing (Si17) for inputting detection data of various switches from the input port, passing the origin of rotating reels 2L, 2C, 2R (reel reference) (Passing position) is detected, the occurrence of a reel rotation error is detected, whether stop preparation is completed (stop preparation completion code is set), stop preparation is complete, and If it is rotating at high speed, the origin passing process (Si18) that permits the operation of the stop switch corresponding to the reel that is rotating, based on detection signals of various switches After sequentially executing the switch input determination process (Si19) for determining whether or not the seed switch satisfies the detection condition, the register saved in the stack area in Si2 is restored (Si20), and the index prohibited in the Si1 step is restored. Is permitted (Si21), and the process returns to the state before the interruption.

  If the timer interrupt is 4 at the step of Si16, the stop position is determined from the stop operation position when the detection of the stop switches 8L, 8C, 8R is determined, and the number of steps after which the stop should be calculated is calculated. Stop switch process (Si22), the number of steps until the stop calculated in the stop switch process is counted, stop process (Si23) to start braking by two-phase excitation when it is time to stop, brake in the stop process Final stop processing (Si24) for three-phase excitation after a certain time from the start, the storage state of the disconnection flag is acquired from the disconnection monitoring IC 50, and if the disconnection flag is stored, an error code indicating a disconnection abnormality error is stored in the register After performing the disconnection confirmation process (Si25) for setting and shifting to the error process shown in FIG. Returning the registers saved in the stack area (Si20), allow interruption prohibited at step Si1 (Si 21), return to the process before the interrupt process.

  In the disconnection confirmation process of Si25, when it is determined that the disconnection flag is stored, the error state due to the disconnection abnormality is controlled, so that the setting key switch 37 is activated and newly set. Until the value is selected and set, the game cannot proceed.

  FIG. 18 is a flowchart showing the control content of the stop switch process executed in the timer interrupt 4 of the timer interrupt process (main) described above by the CPU 41a.

  In the stop switch process, first, for all reels in the order of left, middle and right, it is determined whether or not a stop operation position has been set for the work on the corresponding reel, that is, whether or not a stop operation has been detected ( If the stop operation is not detected for all the reels (Si101, Si102), the stop switch process is terminated and the process returns to the flowchart of FIG.

  If any reel stop operation is detected in step Si101, the process proceeds to step Si103, the stop control table corresponding to the reel is referred to, and the work corresponding to the stop reel is set. From the area number including the number of steps at the stop operation position, the area number to be the stop position is specified, and the process proceeds to step Si104.

  In the step of Si 104, the number of steps required from the current reel reference position to the stop position specified in the step of Si 103 is calculated, and after setting the calculated number of steps, the stop switch process is terminated. Returning to the flowchart of FIG.

  FIG. 19 shows a power interruption interrupt process (main) executed by the CPU 41a in response to the occurrence of an interrupt 2, that is, when a voltage drop signal from the power interruption detection circuit 48 is input, interrupting the execution process or game process It is a flowchart which shows the control content of.

  In the power interruption interruption process (main), first, interruption is prohibited (Sk1). That is, other interrupt processing is prohibited from being executed at the start of the power interruption interrupt processing (main). Next, all registers that may be in use are saved in the stack area (Sk2). Note that the values of the I register and IY register described above are used, but are not saved here because the same fixed value is always set with the initialization at the time of startup.

  Next, the detection data of the voltage drop signal is acquired from the input port, and it is determined whether or not the voltage drop signal is input (Sk3). At this time, if the voltage drop signal is not input, the register saved in the stack area in Sk2 is restored (Sk4), the interrupt prohibited in the Sk1 step is permitted (Sk5), and the process before the interrupt is performed. Return.

  If a voltage drop signal is input in step Sk3, the destruction diagnosis data (5A (H) in this embodiment) is set (Sk6), and all output ports are initialized (Sk7). . Next, the RAM parity adjustment data is calculated and set so that the exclusive OR of all the storage areas (including the unused area and the unused stack area) of the RAM 41c becomes 0 (Sk8), and access to the RAM 41c is performed. It is prohibited (Sk9).

  Then, except for the determination as to whether or not the voltage drop signal is input (Sk10, where Sk10 is the same process as Sk3), the process enters a loop process in which no process is performed. That is, when the voltage decreases as it is, the operation is stopped internally. Therefore, the CPU 41a reliably stops operation when the power is interrupted. Further, in this loop processing, when the voltage recovers and the voltage drop signal is not input, the above-described startup processing is executed, and if the RAM parity is 0 and the destructive diagnosis data is normal, the original processing is performed. It will return to.

  In this embodiment, after the access to the RAM 41c is prohibited, the output state of the voltage drop signal is monitored, and when the voltage drop signal is not input, it is determined that the voltage is restored, and the process proceeds to the startup process. However, no processing is performed in the loop processing, and the voltage is recovered while the loop processing is being performed, and the process proceeds to the start-up processing based on the input of the reset signal from the reset circuit 49. You may make it do.

  Next, various control contents executed by the CPU 91a of the sub-control unit 91 mounted on the effect control board 90 will be described based on the flowchart of FIG.

  When a reset signal is input from the reset circuit 95 to the sub control unit 91, the CPU 91a performs a start process (sub) illustrated in FIG.

  In the startup process (sub), after initialization of built-in devices and peripheral ICs (excluding the door opening detection IC 98), interrupt mode, stack pointer, etc. (Sr1), access to the RAM 91c is permitted (Sr2). Then, the RAM parity of all the storage areas of the RAM 91c is calculated (Sr3), and it is determined whether or not the RAM parity is 0 (Sr4).

  If the data in the RAM 91c is normal, the RAM parity should be 0. If the RAM parity is 0 in the step Sr4, the data stored in the RAM 91c is normal, and the process proceeds to the step Sr5. The production state before power interruption is restored. In step Sr5, after setting the last control pattern executed before power interruption, only command reception interrupt processing is permitted (Sr6), and the process proceeds to step Sr7.

  If the RAM parity is not 0 in step Sr4, the data stored in the RAM 91c is not normal, so the RAM 91c is initialized (Sr13), the standby pattern is set as the control pattern (Sr14), and the command is received. Only the interrupt process is permitted (Sr6), and the process proceeds to step Sr7.

  In step Sr7, it is determined whether an initialization command has been received. If no initialization command has been received, the process proceeds to step Sr8, in which it is determined whether a power-on command has been received. If the initialization command is received, the RAM 91c is initialized (Sr15), the setting notification pattern is set as a control pattern (Sr16), and the process proceeds to Sr11.

  In step Sr8, if the power-on command is not received, the process returns to step Sr7 again. If the power-on command is received, the process proceeds to step Sr9.

  In step Sr9, based on the power-on command received in step Sr8, it is determined whether or not a special role is elected in the state before power interruption (Sr13), and the special role is elected in the state before power interruption. If the special role notification pattern for notifying the winning of the special role is set as the control pattern (Sr10), the liquid crystal display 51, the effect effect LED 52, the speakers 53 and 54, the reels are set according to the set control pattern. An effect control process for controlling various effect devices such as the LED 55 is executed (Sr11), all interruptions are permitted (Sr12), and the process proceeds to a loop process.

  Further, in the step Sr9, when the special role is not elected in the state before the power interruption, the liquid crystal display according to the control pattern set in the step Sr5, that is, the control pattern set before the power interruption. 51, an effect control process for controlling various effect devices such as the effect effect LED 52, the speakers 53 and 54, and the reel LED 55 is executed (Sr11), all interruptions are permitted (Sr11), and the process proceeds to the loop process. That is, as the timer interrupt process is permitted at this time, various effects based on the reception of the command can be executed.

  As described above, in the slot machine 1 according to the present embodiment, one (1) or one (2) that may be won at the same time as the special role is won, and one (1) or one that is won. If you missed (2) and you haven't won any of the roles, you can stop the chances that won't stop. Can increase the player's expectation of

  In addition, when any of the roles is not won by internal lottery (losing), that is, in the state of occupying most of the normal times, chances will not stop, and any special role, 1 (1 ) Or one (2) wins, or a watermelon wins and a missed opportunity can be derived. For this reason, among all the stop control tables, when all the reels are rotating, a stop control table uniquely determined for the internal winning state for each gaming state is selected, and the selected stop control is selected. The reel stop control is performed according to the table, and if any reel has already stopped, the internal winning state for each gaming state, the stop operation position (or stop position) of the stopped reel Even if a stop control table that is uniquely determined is selected and reel stop control is performed in accordance with the selected stop control table, the chances of the chances being met at an appropriate rate without being affected by the skill of the player. It can be derived.

  In addition, the left reel is stopped at a specific operation timing (in this embodiment, region numbers 11 to 13), and the left reel has a chance to display the region numbers 5, 6, and 7 and region numbers 6, 7, and 8. When the eye stops, the chance that the left reel will be the display result of the area number 7, 8, 9 is more likely to be won as a special role than when the eye stops, so the reel always has the same operation timing. Even when a game is played while performing a stop operation, the player's expectation for winning the special role can be changed according to the display result stopped at that time.

  Also, a stop operation position where both cherry and watermelon can be won, a stop operation position where one (1) can be won, and a stop operation position where one (2) can be won , Do not overlap, cannot stop the cherry and watermelon with one (1) or one (2) at the same time, and when the cherry or watermelon wins, one (1) Alternatively, since more medals are awarded than when one (2) wins, the stop operation position where both cherry and watermelon can be positively won, that is, one (1), one (2) ) Can be encouraged to the player at the stop operation position, and as a result, the chances for chances to be derived can be increased, and the player's expectation for winning the special role can be improved. Target It is possible to increase.

  Further, in the present embodiment, when the left reel is stopped for the first time, a stop operation capable of simultaneously aiming at two kinds of symbols out of the constituent symbols of watermelon, cherry, one (1), and one (2). Among the positions, a stop operation position at which the cherry and watermelon configuration symbols can be aimed at simultaneously, that is, when a game is performed by performing a stop operation of the left reel at the timing of area numbers 11 to 13, other stop operation positions Since the expected payout value of the medal is the highest compared to the case where the game is performed by performing the stop operation of the left reel at the timing of, the stop operation position that can win both the cherry and the watermelon more actively, That is, it is possible to prompt the player to perform an operation at the stop operation position where one (1) or one (2) is missed.

  In addition, one piece (1) or one piece (2) that can stop chance chances by missing is the number of medals necessary to set the maximum bet number (3) that can be set for one game. This is a prize that involves paying out 3 or less (1) medals. Therefore, even if 1 (1) or 1 (2) is won by internal lottery and the player cannot win, The winning probability of 1 (1) and 1 (2) does not greatly affect the payout rate of the slot machine 1, so that, for example, 1 (1) It is also possible to increase the probability that one (2) winning is permitted and increase the chance that the chances can be stopped, thereby effectively increasing the player's expectation for the special role.

  In addition, since the number of medals to be paid out with one (1) and one (2) winnings is one required to set the minimum number of bets for one game, the most slots The payout rate of the machine 1 can be hardly affected.

  In this embodiment, one medal is paid out to the player with the winning of one (1) and one (2). The number of medals to be paid out with the occurrence is not limited to one, and the number of medals to be paid out with the occurrence of a specific award that can derive a chance is preferably smaller, but at least for one game If the number of medals required for setting the maximum betable number (3 in this embodiment) (three in this embodiment) is less than or equal to, the payout rate of the slot machine 1 can be hardly affected.

  In addition, in this embodiment, cherry and watermelon are not only when one (1) and one (2) that may be won at the same time as the special role are missed, but also when the special role is won. When the left reel is stopped at the stop operation position where it is possible to aim at the same time, it is possible to stop the chance eye. Expectation can be raised.

  In addition, in this embodiment, not only when one piece (1) or one piece (2) that may be won at the same time as a special role is missed, but also when a watermelon or bell is won, When the left reel is stopped at the stop operation position where watermelon can be aimed at the same time, when the left reel is stopped, it becomes possible to stop the display result that constitutes the chance eye and configure the chance eye It is possible to increase the chances of the display result to be stopped, so that it is possible to maintain the player's expectation for winning the special role. In addition, when the display result that configures the chance eye is stopped by stopping the left reel, it may be due to the winning of a watermelon or a bell, or one piece (1 ) Since it is not possible to determine whether one (2) is missed, it is possible to effectively maintain the player's expectation until all the reels finally stop.

  Furthermore, in the present embodiment, when a watermelon is won, when a stop other than the left reel is set as the first stop, and then the stop operation of the left reel is performed, the watermelon is already dropped on the already stopped reel. When the left reel is stopped at the stop operation position where it is possible to aim at cherry and watermelon at the same time, it becomes possible to stop the chance eye, so it becomes possible to increase the chance that the chance eye stops, It is possible to maintain the player's expectation for winning the special role.

  In the present embodiment, the area numbers 5, 6, and 7 and the area numbers 6 and 7 are only selected when one (2) that is more likely to be elected simultaneously with the special role than the one (1) is elected.・ The chance of the display result of 8 is stopped, but when a special role is elected alone, or when the operation other than the left reel is made the first stop and then the left reel is stopped In addition, even when a watermelon is dropped out on a reel that has already been stopped, the chances that are the display results of the region numbers 5, 6, and 7 and the region numbers 6, 7, and 8 may be stopped. However, if a watermelon is missed, the region number 5, 6, 7 and region number only when the stop operation position or stop position of the already stopped reel is a specific limited stop operation position or stop position. It is preferable that the chance of the display result of 6, 7, 8 can be stopped, and in this way, when the special role is not won, the area numbers 5, 6, 7 and the area numbers 6, 7・ The percentage of chance chances that appear as the display result of 8 can be suppressed, and the special role is won when the chances that become the display results of area numbers 5, 6, and 7 and area numbers 6, 7, and 8 stop. It is possible to effectively increase the player's expectation for

  In this embodiment, the winning combination of cherry is determined by stopping the combination of “cherry-any-any” on the winning line. For example, the combination of “cherry-cherry-any” is determined. Stopping on the winning line, that is, the winning of cherry is determined based on the combination of display results that are not determined only by the stopping result of the left reel, and the cherry stops at a specific position on the left reel, and all If the winning combination does not result in any combination of winnings when the reel stops, the left reel is stopped at the stop operation position where the cherry wins and the cherry and watermelon can be aimed at the same time. When the left reel is stopped, display results (including cherries) that lead to chances are derived when the left reel is stopped. In this way, even when a cherry is won, when the left reel is stopped, it is possible to stop the display result constituting the chance eye and constitute the chance eye. Since it is possible to increase the chances of the display result being stopped, it is possible to maintain the player's expectation for winning the special role. In addition, when the display result that constitutes the chance eye is stopped by stopping the left reel, it may be due to the winning of cherry, or one piece (1) that may be won simultaneously with the special role, Since it cannot be determined whether one (2) has been missed, it is possible to effectively maintain the player's expectation until all reels have finally stopped.

  Further, in the slot machine 1 of this embodiment, during the regular bonus, when a small role other than the bell is elected, the bell is always elected at the same time, and the combination of the bells with the largest number of payouts is drawn into the winning line. Since a priority is given, if one of the small roles is elected during the regular bonus, the player can always win the bell regardless of the operation timing of the stop switches 8L, 8C, 8R by the player. ing. In other words, even if a role with a smaller number of payouts than the bell, such as cherry, watermelon, 1 (1), 1 (2), is won in the regular bonus, the bell wins and the cherry, watermelon, 1 (1), 1 The number of medals that can be earned during the regular bonus because the number of medals (2) can be won more than when the prize was won, and cherry, watermelon, 1 (1), 1 (2) were won. Will not decrease.

  In the present embodiment, the bell with the largest payout number in the regular bonus is made to win simultaneously when a small role smaller than the payout number of the bell is won. However, if it is not the most paying small role in the regular bonus, but the most medals are awarded during the regular bonus by stopping on multiple winning lines, such small role will be You may make it win at the same time as a small role with a smaller number of payouts.

  Also, in this embodiment, the bell which is the small payout with the largest payout number in all gaming states is simultaneously won when the small role with a smaller payout number is won in the regular bonus. If at least a small role with the highest number of payouts is selected at the same time when a small number with a smaller number of payouts is elected at the same time during the regular bonus, The number of medals that can be earned in a regular bonus is reduced. It does not have to be a small role with a large number of payouts.

  In the slot machine 1 of the present embodiment, a plurality of stop controls in which stop positions (display results) are uniquely determined with respect to the stop operation position (area assigned to the number of steps from the reel reference position). When all reels are rotating in the table, a stop control table uniquely determined for the internal winning state for each gaming state is selected, and reel stop control is performed according to the selected stop control table. In the case where any of the reels is already stopped, a stop control table uniquely determined for the internal winning state for each gaming state and the stop operation position of the stopped reel is provided. The reel stop control is performed according to the selected stop control table, and the gaming state, the internal winning state, the reel When all of the stop conditions (and the stop operation position (stop operation timing) of the stopped reel) are the same, the reel stop control is performed based on the same stop control table, that is, the same control pattern. Therefore, as in the prior art, one stop control table is selected from a plurality of stop control tables for one internal winning state by a lottery different from the internal lottery (for example, a lottery for reel control). Further, there is no need to make a selection, and the control for stopping the reel does not become complicated.

  In addition, when any of the reels is already stopped, a stop control table uniquely determined for the internal winning state for each gaming state and the stop operation position of the stopped reel is selected. Therefore, even when the gaming state and the internal winning state are the same, and the stop position (stop symbol) of the stopped reel is the same, the stop operation position of the stopped reel is different. Since the stop control table may be applied, the display results of the reels can be made more diverse.

  Also, in this embodiment, at the start of reel rotation, a stop control table uniquely determined for the internal winning state for each gaming state is selected for all reels, and the selected stop control table is selected. Each time the reels are controlled to stop, each time the reels stop, for each spinning reel, the internal winning state for each gaming state, the stop operation position of the stopped reel, that is, any one reel A stop control table uniquely determined for a combination of stop operation positions of stopped reels in a stopped state, and a combination of stop operation positions of two stopped reels in a state where any two reels are stopped is selected. The reel stop control is performed in accordance with the selected stop control table. When the reels of the reels are stopped, select the stop control table uniquely determined for the spinning reels, the internal winning state for each gaming state, and the stop operation position of the stopped reels. The reel stop control is performed according to the stop control table, and when one of the reels stops (when two reels stop), no new stop control table is selected and all the reels rotate. The remaining reels may be controlled to stop according to the stop control table selected when any one of the reels stops in this state.

  Further, when any one of the reels stops, a stop control table uniquely determined with respect to the spinning reel, the internal winning state for each gaming state, and the stop operation position of the stopped reel. Is selected, the reel stop control is performed according to the selected stop control table, and when one of the reels stops (when two reels stop), the internal winning state for each of the gaming states, first A stop control table that is uniquely determined for the stop operation position of the reel that has stopped last or the stop operation position of the reel that has stopped last is selected, and the stop control of the reel is performed according to the selected stop control table. good.

  Further, in this embodiment, when any of the reels is already stopped, the internal winning state for each gaming state, the stop state of the reel, and the stop operation position of the stopped reel are uniquely determined. The reel stop control is performed in accordance with the set stop control table, but when any reel has already stopped, the internal winning state for each gaming state, the reel stop state, and The reel stop control may be performed according to a stop control table uniquely defined for the stop operation position of the stopped reel.

  In addition, when any one of the reels is stopped, a stop control table that is uniquely determined with respect to the spinning reels, the internal winning state for each gaming state, and the stop position of the stopped reels. Select and perform reel stop control according to the selected stop control table, and when one of the reels stops (when two reels stop), no new stop control table is selected and all The stop control of the remaining reels may be performed according to the stop control table selected when any one of the reels stops while the reels are rotating.

  In addition, when any one of the reels is stopped, a stop control table that is uniquely determined with respect to the spinning reels, the internal winning state for each gaming state, and the stop position of the stopped reels. Select and perform reel stop control according to the selected stop control table, and when one of the reels stops (when two reels stop), the internal winning state for each of the gaming states, first A stop control table uniquely determined for the stop position of the stopped reel or the last stopped reel may be selected, and the reel stop control may be performed according to the selected stop control table.

  Further, in this embodiment, when any two reels are stopped, the combination of the internal winning state for each gaming state and the stop operation position of the stopped reel is uniquely set for the spinning reel. A predetermined stop control table is selected, and reel stop control is performed according to the selected stop control table. For example, when any two reels stop, Stop control table uniquely determined for the internal winning state for each of the gaming states, the stop operation position of any one of the stopped reels, and the stop positions of the remaining reels of the stopped reels And stop control of the reels may be performed according to the selected stop control table.

  In addition, when any one reel is stopped, a stop control table that is uniquely determined with respect to the spinning reel, the internal winning state for each gaming state, and the stop operation position of the stopped reel. When any two reels are stopped, a stop control table uniquely determined for the combination of the internal winning state for each gaming state and the stop position of the stopped reel is selected and selected. The reel stop control may be performed according to the stop control table.

  In addition, when any one reel is stopped, an internal winning state for each gaming state and a stop control table uniquely determined for the stopped position of the stopped reel are selected for the spinning reel. Then, when any two reels are stopped, a stop control table uniquely determined for the combination of the internal winning state for each gaming state and the stop operation position of the stopped reel is selected and selected. The reel stop control may be performed according to the stop control table.

  In addition, when any one reel is stopped, an internal winning state for each gaming state and a stop control table uniquely determined for the stopped position of the stopped reel are selected for the spinning reel. When any two reels are stopped, the internal winning state for each gaming state, the stop operation position of any one of the stopped reels, the remaining reels of the stopped reels A stop control table uniquely determined for the stop position may be selected, and the reel stop control may be performed according to the selected stop control table.

  Further, in these cases, the stop operation position of the reel that has been stopped is determined in an area in which the 1/2 symbol fluctuates, that is, in a unit less than the range in which one symbol fluctuates, and is unique to the stop operation position. The reel stop control is performed according to the stop control table that is defined in a specific manner, that is, different stop control tables can be selected for different number of steps within a range where one symbol fluctuates from the number of steps at which a certain symbol is located at the reference position. In this way, even if the stop position of the stopped reel is the same, and the timing at which the stop operation is performed is within the range where one symbol fluctuates, it is applied to other reels. Since the stop control table can be changed, the display results of each reel can be further diversified.

  In addition, for example, in the case of not winning any combination in the normal gaming state (losing), the same operation is performed when a stop operation is performed within a range of area numbers where the same stop position is determined on a specific reel. However, only when a stop operation is performed in an area with a specific area number among the area numbers where the same stop position is determined, the chance control is configured as a stop control table for other reels. When a stop control table capable of deriving a display result is selected and a stop operation is performed in an area other than a specific area number among the area numbers where the same stop position is determined, another reel It is preferable to select a stop control table capable of deriving the display result constituting the chance as the stop control table. As a result, even if the stop position of the reel at the time when the specific reel is stopped is the same, the stop operation position is different so that the chance is finally controlled so that it can be derived, and the control cannot be derived Therefore, it is possible to prevent the display result of the reel from becoming monotonous when none of the roles is won in the normal gaming state (losing).

  Furthermore, in this case, when one of the bonuses is won in the normal gaming state, among the area numbers for which the same stop position is determined, no combination is won in the normal gaming state. For many area numbers, it is preferable to select a stop control table capable of deriving a display result that constitutes a chance as a stop control table for other reels. In the case where any bonus is won in the game, the chances are derived at a higher rate than in the case where none of the roles are won in the normal gaming state. It is possible to increase the player's expectation for winning the bonus.

  Further, when any of the reels is already stopped, the stop control uniquely determined for the internal winning state, the reel stop state, and the stop operation position of the stopped reel for each gaming state. In the reel stop control according to the table, each time the reel stops, the reel to be stopped is either the left reel, the middle reel, or the right reel, the area number of the stop operation position of the corresponding reel, the corresponding It is preferable that a reel stop command capable of specifying the area number of the stop position of the reel to be transmitted is transmitted to the sub-control unit 91. In this way, the CPU 91a of the sub-control unit 91 can detect when the reel is stopped. In addition, it is possible to perform different effects depending on not only the stop position of the reel but also the stop operation position.

  In particular, when no combination is won in the normal gaming state (losing), the same display is displayed when a stop operation is performed within the range of the area number where the same stop position is determined on a specific reel. The result is derived, but only when the stop operation is performed in the area of the specific area number among the area numbers where the same stop position is determined, the display that configures the chance as the stop control table of the other reels Select a stop control table that can derive the result, and stop other reels when a stop operation is performed in an area other than a specific area number among the area numbers where the same stop position is defined As a control table, a stop control table capable of deriving a display result constituting an opportunity is selected, and any bonus is won in the normal gaming state. As a stop control table for other reels, the area numbers for which the same stop position is determined are larger than those in the case where no combination is won in the normal gaming state. When a stop control table capable of deriving a display result constituting a chance eye is selected, when the stop operation position satisfies the derivation condition of the chance eye when the reel stop command is received, that is, the chance eye When the stop control table from which the display result to be configured can be derived is a selected stop operation position, the ratio is higher than when other stop operation positions that do not satisfy the chance derivation condition but have the same stop position are used. Therefore, a special performance (for example, unusual stop sound, etc.) that informs the possibility of winning any special role may be performed. By doing so, the special effect is performed when the specific reel is stopped, which increases the possibility that the chance chance is finally derived as compared to the case where the special effect is not performed when the specific reel is stopped, As the special performance is performed, it is possible to effectively increase the player's expectation for the derivation of the chance and the winning of the special role.

  Further, in this embodiment, the number of frames to be drawn (stop position when a stop operation is detected in the range) for each range of a plurality of consecutive steps (in this embodiment, 4 steps each having one symbol change). Since the reel stop control is performed using the uniquely determined stop control table, the capacity of the table creation data for creating the stop control table can be greatly reduced.

  In this embodiment, a stop control table is used in which the number of frames to be drawn is uniquely determined for each unit of the area in which one symbol fluctuates. That is, the reel stop control may be performed using a stop control table in which the number of frames to be drawn (stop position) is uniquely determined for each unit less than the range in which one symbol fluctuates. That is, the reel stop control may be performed using a stop control table in which different stop positions are set for different number of steps within a range in which one symbol fluctuates from the number of steps at which a certain symbol is located at the reference position. In this way, even if it is within the range where one symbol fluctuates, the display result derived by the different timing of the stop operation can be changed. The display result of the reel can be derived in such a manner.

  In this embodiment, when the main control unit 41 is activated, the state before power interruption is restored, and when the special role is elected before power interruption, the CPU 41a transmits a power-on command indicating that the special role is elected. When the sub-control unit 91 receives a power-on command indicating that the special role is won, the sub-control unit 91 executes a notification effect indicating that the special role is won, and until the notification effect receives a prize determination command indicating that the special role is won. In other words, it is continuously executed until the winning special role is won.

  Further, the sub-control unit 91 produces the effect even if the backup is normal until it receives a power-on command or an initialization command indicating that the control state of the main control unit 41 has been initialized as will be described later. Without returning to the state, even if another command is received, the production is not controlled accordingly. For this reason, even if the command transmission lines of the main control unit 41 and the sub control unit 91 are disconnected at the time of startup and the main control unit 41 and the sub control unit 91 are connected thereafter, the sub control unit 91 can Since the initialization command is not received, the production control is not performed, and even if the command transmission line of the main control unit 41 and the sub control unit 91 is disconnected at the time of activation, the power-on command is issued on the sub control unit 91 side. It is impossible to avoid the reception of the special role and to avoid the execution of the announcement effect indicating that the special role is won. Thus, when the main control unit 41 is activated, it returns to the state before the power interruption, and from before the power interruption. When the special role is elected, the winning of the special role is always notified.

  On the other hand, it is necessary to turn off the power once to connect unauthorized tools such as driving tools (disconnecting the connector without turning off the power). With the above configuration, the connector is forcibly released. Even if the special tool is won by using a driving tool, it can be easily determined from the outside that the special role is won when the main control unit 41 is restarted. In addition, it is possible to effectively prevent illegal sales such as providing the gaming machine with the slot machine 1 set in a state in which the special role is won using the driving tool at the start of the business of the game shop.

  In addition, the notice effect is continuously executed until a winning judgment command indicating the winning of the special role is received, that is, until the winning special role is won, so that the special role is won, that is, the winning flag of the special role is set. The notification effect will not stop until it is cleared, and it will not be possible to cancel the notification effect while maintaining the special role election by the amusement store. Unauthorized sales such as providing the slot machine 1 set to "" to a player at the start of business at a game shop can be further effectively prevented.

  Further, in this embodiment, when the main control unit 41 is activated, it returns to the state before the power interruption, and when the special role is elected before the power interruption, the CPU 41a indicates a power-on command indicating that the special role is elected. , And the sub-control unit 91 receives a power-on command indicating that the special role is won, so that the sub-control unit 91 controls the notice display effect indicating that the special role is won, the effect effect LED 52, This is executed by a production device such as the speakers 53 and 54, the reel LED 55, etc. Even if the special role is won illegally, when the main control unit 41 is restarted, the special role is won. The slot machine is set in a state where the special role is won using a driving tool and is provided to the player at the start of the game shop operation. Do It said was an illegal business can be more reliably prevented.

  In this embodiment, the release of the connector connection between the game control board 40 and the effect control board 90 is restricted by the connector restricting member. After the main control unit 41 is activated, the effect control board By connecting 90, it becomes difficult to craft such that the special role is not notified, so that illegal sales by an amusement store can be prevented more reliably. Further, the connector restricting member is configured to be able to restrict the removal of the cable side connector from the board side connector connected to each other, and the connection release restriction that makes the release impossible unless the release restricting part related to the connection with the connector is destroyed. When the state is formed and the connection release restriction state is released, the trace remains so that the release restriction part must be destroyed in order to release the connection between the connectors. Since it is extremely difficult to form the connection release restriction state again after releasing the connection, and it takes time and effort, it is possible to more effectively prevent the fraud.

  In the present embodiment, the electrical connection state between the game control board 40 and the effect control board 90 is monitored during a power failure, and the electrical connection state between the game control board 40 and the effect control board 90 is monitored. Is released, the game control board 40 has a disconnection monitoring IC 50 that stores a disconnection flag indicating that, and the CPU 41a requests the disconnection monitoring IC 50 to check the disconnection flag at the time of activation. When the disconnection flag is stored based on the reply from the accompanying disconnection monitoring IC 50 and the disconnection flag is stored, that is, the electrical connection state between the game control board 40 and the effect control board 90 is released. In such a case, it is determined that the disconnection is abnormal, and an error state due to the disconnection abnormality error is controlled to disable the progress of the game, and the CPU 41a is used in the RAM 41c area. Since all the areas except for the above area are initialized and cannot be restored to the original state, after the main control unit 41 is activated, the special control board 90 is connected so that the special role is not notified. In this case, since the RAM 41c is initialized and cannot be restored to the original state, illegal sales by the amusement store can be prevented more reliably.

  In this embodiment, the special device winning is notified by the effect device controlled by the sub-control unit 91. However, when the main control unit 41 is activated, it returns to the state before the power interruption, and When the special role is elected before the power interruption, the credit display 11, the game auxiliary display 12, and the payout display 13 directly controlled by the main control unit 41 may notify the special role. good. In addition, a notification LED for notifying the winning of the special role is provided as an electronic component that is directly controlled by the main control unit 41. When the main control unit 41 is activated, it returns to the state before the power interruption, and the special role is selected before the power interruption. In this case, the notification LED may be used to notify the winning of the special role.

  Further, in this embodiment, a connector restricting member is used for connector connection between the electronic control unit (input medal sensor 31) that inputs or outputs a signal to the game control board 40 and the game control board 40 as the game progresses. The use of unauthorized devices is also prevented by restricting the release of connections between the connectors, but when the main control unit 41 is activated, it returns to the state before the power interruption, and the special role is elected before the power interruption. In this case, it is possible to prevent the use of a driving tool regardless of whether or not the structure for restricting the insertion / removal between the connectors is made by notifying that effect. In this way, it is not necessary to change the structure of parts in order to regulate the insertion and removal of connectors, and maintainability in the event of a failure, etc. It can also be over.

  In this embodiment, the disconnection monitoring IC 50 also monitors the electrical connection state between the game control board 40 and the inserted medal sensor 31 at the time of a power failure, and between the game control board 40 and the inserted medal sensor 31. When the electrical connection state is released, a disconnection flag indicating that is stored, and the CPU 41a requests the disconnection monitoring IC 50 to check the disconnection flag at the time of activation, and the disconnection monitoring IC 50 accompanying this is requested. The storage state of the disconnection flag is acquired based on the reply from and when the disconnection flag is stored, that is, when the electrical connection state between the game control board 40 and the inserted medal sensor 31 is released, It is determined that the disconnection is abnormal, and an error state due to the disconnection abnormality error is controlled to disable the progress of the game, and the CPU 41 is out of the area of the RAM 41c. There all the area except the area in use is initialized and becomes impossible return to the original state.

  On the other hand, in order to connect an unauthorized device such as a driving device, it is necessary to insert and remove the connector. Since the disconnection flag is stored in the disconnection monitoring IC 50 and the CPU 41a is activated, all the areas of the RAM 41c other than the area in use by the CPU 41a are initialized. It is possible to effectively prevent illegal sales such as providing a slot machine set in a state in which a special role is won using a driving tool to a player at the start of a game shop business.

  Further, the disconnection monitoring IC 50 monitors the electrical connection state between the game control board 40 and the inserted medal sensor 31 even when energized, and the electrical connection between the game control board 40 and the inserted medal sensor 31. When the state is released, the disconnection flag indicating that is stored, and the CPU 41a periodically checks the storage state of the disconnection flag in the timer interruption process even after the activation, and the disconnection flag is stored. In such a case, it is determined that the disconnection is abnormal, and an error state due to the disconnection abnormality error is controlled to disable the progress of the game, and all areas of the RAM 41c other than the area being used by the CPU 41a are initialized, Since it is impossible to return to the original state, the disconnection monitoring IC 50 can be used even when the connection of the connector is released to replace it with a normal connector without turning off the power. The disconnection flag is stored, and accordingly, an error state due to disconnection abnormality is controlled, and all areas of the RAM 41c other than the area in use by the CPU 41a are initialized. It is possible to more surely prevent illegal sales such as providing a slot machine set in a state where a winning combination is won to a player at the start of a game shop business.

  Also, in this embodiment, once controlled to an error state due to a disconnection abnormality error, the game progresses unless the setting change mode is entered and a setting value is newly selected and set based on the setting changing operation. The disabled state is not released. That is, not the setting value automatically set by the slot machine with the initialization of the RAM 41c, but the setting value selected and set based on the setting change operation (generally, the setting change operation is an employee of a game shop) Therefore, it is ensured that the game is played based on the setting value selected by the amusement shop side), so that the fairness of the game can be achieved.

  In this embodiment, when the CPU 41a determines that the disconnection is abnormal and controls the error state due to the disconnection abnormality error, all the areas of the RAM 41c other than the area in use by the CPU 41a are initialized. Although the configuration is such that the original state cannot be restored, the RAM 41c is not initialized in the error state due to the disconnection abnormality error, but after that, the RAM 41c is initialized (in this embodiment, the setting change mode is entered). A transition operation corresponds to this, but separately from this, an initialization switch for initializing the RAM 41c by being detected when the power is turned on may be provided, and the initialization operation of the RAM 41c by the initialization switch may be applied. ), The error state may be canceled and the game can be made possible. Even if the special device is illegally set using a special instrument, the disconnection flag is stored in the disconnection monitoring IC 50 and the CPU 41a is activated by releasing the connection of the connector in order to replace it with a regular connector. At this time, since the RAM 41c is initialized and the progress of the game is disabled until the RAM 41c is initialized, the slot machine set in the state where the special role is won using the driving tool is changed to the amusement store. It is possible to effectively prevent illegal sales such as providing to a player at the start of business.

  Further, in this embodiment, the connector restricting member is provided only for the connector connection between the electronic control component (inserted medal sensor 31) that inputs or outputs a signal to the game control board 40 and the game control board 40 as the game progresses. The use of unauthorized devices is also prevented by restricting the release of the connection between the connectors, but the state of electrical connection between the game control board 40 and the inserted medal sensor 31 is monitored, and the game control board When the electrical connection state between 40 and the inserted medal sensor 31 is released, a disconnection flag indicating the fact is stored, and the CPU 41a confirms the storage state of the disconnection flag at the start and after the start. If the disconnection flag is stored, it is determined that the disconnection is abnormal, and the error state due to the disconnection abnormality error is controlled to disable the progress of the game. Initialize all the areas of the M41c area except for the areas that are being used by the CPU 41a, or disable the progress of the game until the RAM 41c is initialized by performing an initialization operation, so that the connectors can be inserted and removed. Regardless of whether or not the structure is restricted, it is possible to prevent the use of a driving tool, so it is possible not to have a structure that restricts the insertion and removal of connectors. In addition to requiring a significant structural change in the parts to regulate, it is possible to improve maintainability in the event of a failure.

  In this embodiment, the disconnection monitoring IC 50 monitors the electrical connection state between the game control board 40 and the inserted medal sensor 31, but signals necessary for the progress of the game are input and output. Electronic components (for example, stop switch 8L, 8C, 8R, etc. in a configuration that does not stop the reel until the reel stop operation is performed after the start of reel rotation). The same effects as described above can be obtained.

  Further, in the present embodiment, the disconnection monitoring IC 50 has an electrical connection between the game control board 40 and an electronic component (inserted medal sensor 31) that inputs or outputs a signal to the game control board 40 as the game progresses. And the game control board 40 between the electronic component (the input medal sensor 31) and the game control board 40 that inputs or outputs a signal to the game control board 40 according to the progress of the game. When the disconnection is determined, the RAM 41c is initialized to prevent unauthorized sales by the game store. However, the backup power source of the main control unit 41 is connected from the game control board 40 to the game control board 40. Cable 600a for wiring connection of operation unit relay board 110, operation unit relay board 110, operation unit relay board 110 and throw-in medal sensor 31 are connected by wiring. Via the cable 601g to be further turned back by the inserted medal sensor 31, and returned to the game control board 40 again via the cable 601g, the operation part relay board 110, and the cable 600a, and supplied to the main control part 41. With such a configuration, the connection between the connectors between the game control board 40 and the inserted medal sensor 31 is released even at one place while the power supply to the slot machine 1 is cut off. As a result, the backup power supply line is cut off, and the data in the RAM 41c of the main control unit 41 cannot be retained and is lost. In other words, when even one connection between the game control board 40 and the inserted medal sensor 31 is released, the backup data held in the RAM 41c of the main control unit 41 is lost. On the other hand, in order to connect an unauthorized device such as a driving device, it is necessary to insert / remove the connector, but even if a special device is selected by using the driving device, the connector must be replaced with a regular connector. Since the data in the RAM 41c is initialized by releasing the connection, the slot machine 1 set in a state in which the special role is elected using the driving tool is provided to the player at the time of starting the business of the game shop. Unauthorized sales such as doing can be prevented.

  Note that when the backup power is returned from the game control board 40 to the game control board 40 via the inserted medal sensor 31 and supplied to the main control unit 41, the connector connection therebetween is released. Although the data in the RAM 41c is lost, an electronic component (for example, a start switch 7 or a reel stop operation is performed after the reel starts rotating) that inputs and outputs signals necessary for the progress of the game. The same effect as described above can be obtained even if the stop switch 8L, 8C, 8R or the like is not used.

  Capacitors and batteries that store backup power are mounted on electronic component mounting boards and relay boards (operation unit relay board 110, etc.) for these electronic parts, which are required to input and output signals necessary for the progress of the game. A backup power supply line from a capacitor or a battery mounted on the mounting board or the relay board is connected to the game control board through a cable together with a signal line of the electronic component and supplied to the main control unit 41. Even in this case, since the data in the RAM 41c is lost when the connector connection between the mounting board or the relay board and the game control board 40 is released, the same effect as described above is obtained. In addition, the game control board 40 can be backed up via a cable from a capacitor or battery mounted on the mounting board or relay board. Therefore, in order to continue supplying the backup power to the main control unit 41 when the cable is disconnected, it is necessary to short-circuit the backup power supply line across the boards. Since it becomes very difficult to release the connector connection in a state in which the backup power supply is continuously supplied, the connection of the driving tool can be effectively prevented.

  Further, in the slot machine 1 of this embodiment, it is determined for each game whether or not the value read from the set value work is in the range of 1 to 6, that is, whether or not the set value used for the internal lottery is in the proper range. If the value read from the set value work is not in the range of 1 to 6, it is controlled to an error state due to a RAM abnormality error, and the progress of the game is disabled. In this embodiment, the value stored in the set value work, that is, the range of the set value that can be selected by the setting change process is a value of 1 to 6, and thus the value stored in the set value work is in the range of 1 to 6. If the value is not, the progress of the game is disabled.

  Further, a process for determining whether or not the set bet number is a bet number according to the gaming state is executed for each game, and the set bet number is not the bet number according to the game state. Control of the error state due to the RAM abnormal error disables the progress of the game. In this embodiment, the number of bets corresponding to each gaming state is determined, but if the game is played with a bet number different from the bet number, is the data stored in the RAM 41c broken? Or, since there is a possibility that an unauthorized program is operating, even if the set bet number is not the bet number according to the game state, the progress of the game is disabled.

  Then, once controlled to an error state due to a RAM abnormality error, the game cannot be progressed unless the setting change mode is entered and a setting value is newly selected and set based on the setting changing operation. Is not released. In other words, if the set value is not appropriate due to garbled data or illegal program operation, or if the set bet number is not the bet number according to the gaming state, the set value automatically set by the slot machine The game is executed based on the setting value selected and set based on the setting change operation (generally, since the setting change operation is performed by an employee of the amusement store, the setting value selected by the amusement store side). Since it is guaranteed that the game will be played, the fairness of the game can be improved.

  Further, in this embodiment, when an abnormality occurs in the data stored in the RAM 41c, the error state due to the RAM abnormality error is controlled, the progress of the game is disabled, and the error state once caused by the RAM abnormality error. If it is controlled, the state in which the progress of the game is disabled will not be released unless the setting change mode is entered and the setting value is newly selected and set based on the setting changing operation. That is, even if an abnormality occurs in the data stored in the RAM 41c, it is not the setting value automatically set by the slot machine, but the setting value selected and set based on the setting change operation (generally, the setting change Since the operation is performed by an employee of the amusement store, it is ensured that the game is performed based on the setting value selected by the amusement store side), so that the fairness of the game can be achieved.

  Further, the data stored in the RAM 41c is abnormal in most cases when the control cannot be continued due to a malfunction such as a power failure or the CPU 41a running out of control. For this reason, in this embodiment, since it is determined whether or not the data is normal only when the CPU 41a is activated after recovering from these states, it is determined whether or not the data stored in the RAM 41c is normal. The determination can be made only in a situation where there is a high possibility that an abnormality has occurred in the data. That is, in a situation where there is a low possibility that an abnormality has occurred in the data, it is not necessary to perform the determination, and the load on the CPU 41a can be reduced.

  In this embodiment, the RAM parity adjustment data is calculated and stored so that the RAM parity based on all the data in the RAM 41c in the power interruption processing (main), that is, the result of the exclusive OR operation is 0. In addition, since it is determined whether or not the data in the RAM 41c is normal by determining whether or not the RAM parity calculated based on the data stored in all areas in the RAM 41c at the time of recovery is 0. This determination can be performed accurately and simply.

  Further, in addition to the RAM parity adjustment data, the destructive diagnosis data whose bit value is not 1 is stored in the RAM 41c in the power interruption processing (main), and the RAM parity is 0 at the time of restoration. Even in such a case, it is further determined whether or not the destruction diagnosis data is normally stored. The data in the RAM 41c is initialized during the power failure, and the state before the power failure cannot actually be restored. Nevertheless, since all the data in the RAM 41c is 0, it is not determined to be normal.

  In particular, in this embodiment, when the connection between the connectors between the game control board 40 and the inserted medal sensor 31 is released even at one place, the backup data held in the RAM 41c of the main control unit 41 is lost. As a result, the destruction diagnosis data is cleared to 00H, so that when started in this state, the CPU 41a can reliably determine a RAM abnormality error and disable the progress of the game.

  In this embodiment, the CPU 41a performs an abnormal winning determination that determines whether or not a combination that is not permitted in the game is on the winning line when all the reels are stopped.

  In the abnormal winning determination, when a combination that has not been won in the internal lottery is prepared, or when a special combination and a general combination are prepared at the same time, it is determined that an abnormal winning is achieved.

  When it is determined that the winning is abnormal, that is, when a winning combination that is not permitted in the game is won, the game is controlled to be in an error state due to an abnormal winning error and the progress of the game is disabled.

  As described above, in this embodiment, when a combination that has not been won in the internal lottery is arranged, or when a special combination and a general combination are won at the same time, that is, when a combination that is not selected is won or a special combination and a general combination are combined. If you win at the same time, there is a possibility that the data has been destroyed or an abnormal program is running, and even in such a case the progress of the game will be disabled, so the fairness of the game Will not be damaged.

  Further, in this embodiment, once an error state due to an abnormal winning error is controlled, the game progresses unless the setting change mode is entered and a setting value is newly selected and set based on the setting changing operation. The disabled state is not released. In other words, when an unacceptable winning combination wins due to garbled data or abnormal program operation, it is not the setting value automatically set by the slot machine, but the setting selected and set based on the setting change operation Since it is ensured that the game is played based on the value (generally, the setting change operation is performed by an employee of the game shop, which is the set value selected by the game shop), the game is fair. be able to.

  As described above, the first embodiment of the present invention has been described with reference to the drawings. However, the present invention is not limited to the first embodiment, and the present invention can be modified or added without departing from the gist of the present invention. Needless to say, it is included.

  For example, in the first embodiment, the table index and the table creation data stored in the ROM 41b are referred to when the reel starts rotating and when the reel stops and the reel that is still rotating still remains. Thus, a stop control table is created for each spinning reel, but the internal winning state for each gaming state and the reel stop status (and the stop position of the stopped reel or the stop of the stopped reel) Operation position) Another stop control table is registered in the ROM 41b in advance, and based on the table index, it is possible to specify the required stop control table according to the internal winning state for each gaming state and the reel stop state. When the reel starts to rotate and when the reel stops and the reel that is still rotating still remains Refers to the table index, for each rotating reel may be set a stop control table.

  In the first embodiment, 21 areas (frames) divided every 8 steps (each symbol) are defined for one reel, and the stop control table corresponds to each area (area number). The stop control table in which the number of frames to be drawn (stop position) is uniquely determined, that is, the stop control table in which the stop position is uniquely determined corresponding to the range of the range in which one symbol fluctuates is used. Although stop control is performed, for example, the number of pull-in steps and the number of pull-in frames (stop position) are uniquely determined for each area less than one symbol, for example, one step, that is, every minimum unit when driving the reel motor. The stop control of the reels may be performed using the stop control table, and in this way, the stop position can be changed in units of the number of steps of the reel motor. It can be further diversified stop position that.

  In the first embodiment, among the plurality of stop control tables that uniquely determine the number of draw-in frames for the stop operation position, the internal winning state of each game state, the reel stop state (and the stop position of the stopped reel) Alternatively, a stop control table uniquely determined for the stop operation position of the stopped reel) is selected, and the stop control of the reel is performed according to the selected stop control table, but the stop position relative to the stop operation position is unique. When a stop operation is detected using a plurality of stop position specification tables determined in advance, when the stop operation is detected, the stop position specification table is referred to and uniquely specified corresponding to the stop operation position. You may make it perform the control which stops a reel in a stop position.

  Further, by defining a stop priority for the stop position, a plurality of stop priority tables that uniquely determine the stop position with respect to the stop operation position (the number of steps from the reel reference position) are used instead of the stop control table. When a stop operation is detected, the stop priority table is referenced, and the stop priorities of all stop positions within the retractable range (up to 5 frames) from the stop operation position are compared, and the highest stop priority is obtained. You may make it perform the control which stops a reel in a stop position.

  Also, select the number of draws that is uniquely determined for each internal winning state of each gaming state and the reel stop status (and the stop position of the stopped reel or the stop operation position of the stopped reel). When a stop operation is performed, if the target stop position is within the range of the selected number of pull-in frames, pull-in control is performed to pull the stop position and stop, and the stop is prohibited. It is also possible to perform kicking control (so-called control method control) in which other stop positions are pulled in and stopped so as not to stop the stop position. Since the stop position is uniquely determined with respect to the stop operation position (number of steps from the reel reference position) by performing the pull-in control and the kick-off control in this way, the control for deriving the display result by the pull-in control and the kick-off control is It can be said that this is a control pattern for uniquely specifying the stop position with respect to the stop operation position.

  In addition, a control pattern uniquely determined for each internal winning state of each gaming state, the stop status of the reel (and the stop position of the stopped reel or the stop operation position of the stopped reel), If the reel stop control is performed according to the control pattern, the reel stop control by the stop control table, the reel stop control by the stop priority table, the reel stop control by the pull-in control and the kicking control are performed in combination. For example, only the reel that has stopped first may be controlled to stop the reel by using the stop control table, and the other reels may be controlled to be stopped by pull-in control and kicking control.

  In the first embodiment, the control is uniquely determined for each internal winning state of each gaming state and the reel stop status (and the stop position of the stopped reel or the stop operation position of the stopped reel). The reel is controlled according to the control pattern selected, but at least the control pattern determined for each internal winning state of each gaming state is selected, and the reel is stopped according to the selected control pattern. Any device that performs control may be used.

  In the first embodiment, a slot machine for setting bets using medals and credits is used. However, the present invention is not limited to this, and a slot machine for setting bets using game balls, It may be a full credit type slot machine that uses only credits to set the number of bets.

  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 a game ball, and a take-in ball that detects a game ball taken in by the ball take-in device In addition to a medal payout mechanism, such as a hopper motor 34 and a payout sensor 35, a ball payout device for paying out a game ball, and a payout ball detection switch for detecting a game ball paid out by the ball payout device It is possible to set a bet number 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 by winning.

  The second embodiment of the present invention will be described below. Since the present embodiment has the same configuration as that of the first embodiment except that the reel symbol arrangement and the reel stop control are different, detailed description thereof is omitted here.

  In this embodiment, as shown in FIG. 21, for the left reel, the stop operation position where “white 7” can be drawn into the winning line is area numbers 4 to 10 and “red 7” can be drawn into the winning line. The stop operation positions become region numbers 1 to 3, 18 to 21, and the stop operation positions at which “watermelon” can be drawn into the winning line are region numbers 11 to 16. That is, in this embodiment, unlike the first embodiment described above, there is no stop operation position where both “white 7” and “watermelon” can be drawn, and both “red 7” and “watermelon” There is no stop position that can be pulled in. For this reason, it becomes impossible to aim at the watermelon and one (1) or one (2) configuration symbol at the same time.

  In the present embodiment, the same as in the first embodiment, the winning probabilities (including special roles and simultaneous winning probabilities) of watermelon, 1 (1), 1 (2) are 1 / 85.3 and 1/97. Since it will be 5, 1/182, the expected payout value of medals when playing a game aiming at these roles alone (the winning probability of the target role x the number of payouts of the target role), that is, aiming at these roles alone When playing a game, the number of medals that can be expected to be paid out per game is approximately 0.0703, 0.0103, and 0.0054 for watermelon, 1 (1), and 1 (2), respectively. Become.

  For this reason, in this embodiment, when the left reel is first stopped, the stop operation position where the watermelon can be won out of the watermelon, one (1), one (2), that is, the region numbers 11 to 11 When a game is performed by stopping the left reel at the timing of 17, the left reel is stopped at the timing of the stop operation position at which one (1), one (2) can be won. This is advantageous for the player compared to the case where the game is played. Furthermore, the stop operation position where the watermelon can be won includes a stop operation position (region numbers 15 to 17) where the cherry can be aimed at the same time, in particular, the stop where the watermelon and the cherry can be aimed at the same time. It is most advantageous for a player when a game is played by performing a stop operation of the left reel at the timing of the operation position.

  Next, in the normal game state, stop control when the left reel is stopped in a state where all reels are still fluctuating, in particular, the timings of the area numbers 15 to 17 which are the stop operation positions advantageous to the player described above. The stop control when the stop operation is performed will be described.

  In the present embodiment, the left reel stop control table applied when no combination is won (losing), the left reel stop control table applied when replay is won (replay), bell In the stop control table for the left reel applied in the case where is won (bell), the number of frames to be drawn in which the area number 14 is specified as the stop position is determined with respect to the stop operation positions of the area numbers 15-17. In the case where any combination is not won, when the replay is won and when the bell is won, if the stop operation of the left reel is performed at the timing of the area numbers 15 to 17, Even if the stop operation of the left reel is performed at any timing among the region numbers 15 to 17, the region number 14 becomes the stop position, and the region numbers 12, 13, and 14 It shows the result is stopped.

  Left reel stop control table applied when watermelon is won (watermelon), left reel stop control table applied when one (1) is won (1 (1)), In the left reel stop control table applied when the special combination is won alone (bonus), the lead-in frame in which the area number 13 is specified as the stop position with respect to the stop operation positions of the area numbers 15 to 17 In the case where the number is determined and a watermelon, one sheet (1), and a special role are elected, and the stop operation of the left reel is performed at the timing of the region numbers 15 to 17, the region numbers 15 to 17 are performed. In any case, the stop operation of the left reel is performed at any timing, and the region number 13 becomes the stop position, and the display results of the region numbers 11, 12, and 13 are stopped. At this time, if the watermelon is elected, the “watermelon is in a stopped state in the winning lines L2 and L4, and the“ watermelon ”is stopped in the drawing range of 4 frames with respect to these winning lines L2 and L4. If you stop the other reels at the timing that can be used, the combination of watermelons will be aligned on the winning line, but if one (1) is won or one of the special roles is won In such a case, since these combinations have already been missed, none of the combinations are arranged when all reels are stopped.

  In the stop control table for the left reel applied when the cherry is won (cherry), the area number 15 is the stop position for the area numbers 15 and 16 among the stop operation positions of the area numbers 15 to 17. When the number of drawn frames to be specified is determined, and the number of drawn frames to which the region number 17 is specified as the stop position is determined with respect to the region number 17, and when the cherry is elected, the region numbers 15 to 17 When the stop operation of the left reel is performed at the timing, the region number 15 or the region number 17 becomes the stop position, and the display result of the region numbers 13, 14, 15 or the display results of the region numbers 15, 16, 17 is the upper row. Or the display result stops at the bottom. At this time, since “Cherry” has already stopped on the winning line, the combination of cherries is always aligned on the winning line by stopping other reels.

  In the stop control table for the left reel applied when one (2) is elected (1 (2)), out of the stop operation positions of the region numbers 15 to 17 with respect to the region numbers 15 and 16 The number of frames to be drawn in which the area number 12 is specified as the stop position is determined, and the number of frames to be drawn in which the area number 13 is specified as the stop position for the area number 17 is determined. In this case, if the stop operation of the left reel is performed at the timing of the region numbers 15 to 17, the region number 12 or the region number 13 becomes the stop position, and the display result of the region numbers 10, 11, 12 or the region numbers 11.12・ The display result is 13. At this time, since one sheet (2) has already been missed, none of the roles are aligned when all reels are stopped.

  As described above, in this embodiment, when the left reel is set to the first stop (stopped first) and the stop operation is performed at the timings of the region numbers 15 to 17, the watermelon, one (1), one ( 2) The display results of area numbers 11, 12, and 13 are stopped only when one of the special roles is elected. In the case of losing, the replay is elected and the bell is elected. In such a case, the display results of the area numbers 11, 12, and 13 are not stopped.

  Furthermore, among these roles, when the watermelon is won, the stop operation is aimed at the “watermelon” on the other reels, so that the watermelon is aligned with the winning line, whereas one (1), If one (2) or any special combination is elected, regardless of the operation timing of the other reels, no combination will be on the winning line when all reels stop. ing.

  Therefore, when the left reel is set to the first stop and the stop operation is performed at the timings of the area numbers 15 to 17, if the display results of the area numbers 11, 12, and 13 are stopped, the special role is won. In the event that none of the roles are in line with the winning line, there is a chance that the player will win a special role or may win the special role at the same time (1 ) Or 1 (2), or you have missed a watermelon, which suggests that you are more likely to win a special role. That is, in this embodiment, when the left reel is set to the first stop and the stop operation is performed at the timings of the region numbers 15 to 17, the display results of the region numbers 11, 12, and 13 are stopped, and any role is played. The display mode that does not align with the winning line does not confirm the winning of the special role, but it is more likely than other display modes (except for the reach that indicates that the special role has been selected). It functions as an opportunity to show the effect.

  Further, in this embodiment, when the left reel is set to the first stop and the stop operation is performed at the timing of the area numbers 15 to 17, the area numbers 10 and 11 are only obtained when one (2) is won. The display result of 12 is stopped. In other cases, the display results of area numbers 10, 11, and 12 are not stopped. Further, in this case, regardless of the operation timing of the other reels, when all the reels are stopped, none of the winning combinations are aligned with the winning line.

  Therefore, when the left reel is set to the first stop and the stop operation is performed at the timings of the area numbers 15 to 17, if the display results of the area numbers 10, 11, and 12 are stopped, one (1) 1 (2), which is more likely to be won at the same time as a special role compared to, will be confirmed, so one less likely to be won at the same time than 1 (2) It is suggested that it is more likely that the player has won the special role than if the display result of the area numbers 11, 12, 13 that can appear even when the watermelon is dropped is stopped. Will be. That is, in this embodiment, when the left reel is set to the first stop and the stop operation is performed at the timings of the area numbers 11 to 13, the display mode in which the display results of the area numbers 10, 11, and 12 are stopped is the area number. The display results of 11, 12, and 13 are stopped, and it functions as an opportunity that is more likely to be won as a special role than in a display mode in which none of the roles match the winning line.

  Further, in this embodiment, when a stop other than the left reel is set as the first stop, and then the left reel is stopped at the timing of the area numbers 15 to 17, the winning combination is aligned with the winning line. With the exception of 1) (1), 1 (2), if any special role has been won, or if the watermelon has been won and the reel has already stopped, ”Is not stopped, that is, when the watermelon is dropped, the display results of the region numbers 11, 12, and 13 are stopped. In other cases, the display results of the region numbers 11, 12, and 13 are not stopped. It has become.

  For this reason, if the other reels are set to the first stop, and the stop operation of the left reel is performed at the timing of the region numbers 15 to 17, the display result of the region numbers 11, 12, and 13 is stopped. Either winning a role, winning one (1) or one (2) with the possibility of winning simultaneously with a special role, or dropping a watermelon on a reel that has already been stopped. It is suggested that there is a high possibility that the role is won. That is, in the present embodiment, the display mode in which the display results of the region numbers 11, 12, and 13 are stopped when the operation other than the left reel is set as the first stop and the stop operation of the left reel is performed at the timing of the region numbers 15 to 17 thereafter. It has come to function as a chance eye.

  As described above, in the slot machine of this embodiment, the left reel is stopped at a specific operation timing (region numbers 15 to 17 in this embodiment), and the left reel displays the display results of region numbers 10, 11, and 12. Since the chance that the left reel is elected as a special role is higher than when the chance that becomes the display result of the area numbers 11, 12, and 13 is stopped when the chance chance is stopped, always the same operation timing Even when a game is played while performing a reel stop operation, the player's expectation for winning the special role can be changed according to the display result stopped at that time.

  Also, the stop operation position where a watermelon can be won overlaps with the stop operation position where one (1) can win and the stop operation position where one (2) can win. In addition, it is not possible to stop the watermelon and one (1) or one (2) at the same time, and when the watermelon wins, one (1) or one (2) wins Since more medals will be awarded, the operation at the stop operation position where the watermelon can be positively won, that is, at the stop operation position where one (1), one (2) is missed, is performed. It is possible to prompt the player, and as a result, it is possible to increase the chances that a chance item is derived, and to effectively increase the player's expectation for winning the special role.

  Further, in this embodiment, when the left reel is first stopped, the left reel is stopped at the stop operation position where the watermelon can be won among the watermelon, one (1), and one (2). Compared to playing a game by performing a stop operation of the left reel at a stop operation position where one (1) or one (2) can be won when a game is performed by performing an operation. Since the expected payout value of medals is higher, the player can perform an operation at the stop operation position where the watermelon can be won even more actively, that is, at the stop operation position where one (1) or one (2) is missed. Can be encouraged.

  In the present embodiment, only when one sheet (2), which is more likely to be elected at the same time as the special role than one (1), has been elected, the chance to be the display result of the area numbers 10, 11, 12 is obtained. The eyes will stop, but if the special role is elected alone, or if the left reel is the first stop and then the left reel is stopped, Even when a watermelon is missed, chances of displaying the region numbers 10, 11, and 12 may be stopped. However, if a watermelon is missed, the display results of the area numbers 10, 11, and 12 are only displayed when the reel is already at a specific limited stop operation position or stop position among the stop operation positions or stop positions of the reels. It is preferable that chance chances to be stopped can be stopped, and in this way, the proportion of chance chances that will be displayed as area numbers 10, 11, and 12 when the special role is not won is suppressed. It is possible to effectively increase the player's expectation for winning the special role when the chance that is the display result of the area numbers 10, 11, and 12 stops.

  As described above, the second embodiment of the present invention has been described with reference to the drawings. However, the present invention is not limited to the second embodiment, and the present invention can be modified or added without departing from the gist of the present invention. Needless to say, it is included. Further, the same or similar configuration as the first embodiment has the same effect as that described in the first embodiment. Further, the modified example illustrated for the first embodiment is also applicable to the second embodiment.
