Description

The present invention relates to a slot machine, and more particularly to a continuous effect that is continuously performed during a continuous effect period over a plurality of games .

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

  The types of winning combinations include small roles with payout of medals, replay roles that allow the next game to be started without setting the number of bets, and transition to a gaming state that is advantageous to the player such as regular bonuses and big bonuses. There is a bonus role with. In particular, the bonus combination is not limited to the winning game, and a large profit can be obtained as a whole over a certain period after the winning. Therefore, the player is most interested in the occurrence of the winning combination.

  In order for a winning combination including a bonus combination to occur, generally, a winning flag must be set by winning an internal lottery performed in advance (usually when a start lever is operated). Here, the winning flag for the bonus combination is different from the winning flag for the small role or the replay, and is not limited to the game won in the internal lottery, but is carried over until winning. Since the internal lottery is performed only as a process inside the machine of the slot machine, it is not possible for the player to know the setting status of the winning flags of each combination including the bonus combination.

  Therefore, in many slot machines, an effect corresponding to the setting status of the winning flag is performed, and the setting status of the winning flag is shown to the player to some extent by this effect (however, it may be shown completely). In particular, the winning flag for the bonus combination is carried over until winning, and the player's interest is high. Therefore, the winning flag is indicated by a continuous effect that lasts longer than one game. In addition, even when the bonus combination winning flag is not actually set, the same continuous performance as when the bonus combination winning flag is set is performed at a predetermined rate to increase the player's expectation. It is intended to improve the fun of gaming.

  By the way, the continuous performance is started according to the conditions established at the time of the start, but the conditions may change during the execution of the continuous performance. For example, when a bonus combination is won during execution of a continuous production started when the bonus combination is not won, there is a change in the content of the continuous production being executed (for example, Patent Document 1). reference). Moreover, although it is applied to the pachinko gaming machine, there is a case in which the period of the continuous production being executed is extended when a predetermined condition such as a start prize is established after the start of the continuous production (for example, Patent Document 2). reference).

Japanese Patent No. 363243 (paragraph 0081) JP 2002-355400 A (paragraph 0015)

  However, in any of Patent Documents 1 and 2, the control of the continuous production being executed is changed midway. For this reason, there has been a problem that the control for the execution of the continuous performance becomes complicated. On the other hand, if the continuous production is ended with the conditions at the start of the continuous production, the conditions established at the end of the production will be different from the contents of the production, causing distrust to the player. There was a risk of feeling.

The present invention does not complicate the control related to the execution of the continuous effect even if a condition different from the condition established at the start after the start of the continuous effect that continues between the continuous effect periods over a plurality of games is established. An object of the present invention is to provide a slot machine that can produce effects according to new conditions.

To achieve the above object, a slot machine according to the present invention includes:
By setting a predetermined number of bets for one game, the game can be started, and the display result is displayed on a variable display device (variable display device 2) that variably displays a plurality of types of identification information each of which can be identified. In a slot machine in which one game is completed by being derived and winning can be generated according to the display result derived to the variable display device,
Includes special display results (regular bonus, big bonus (1), big bonus (2)) accompanying the transition of the gaming state to the special gaming state before the display result of the variable display device is derived for each game A pre-determining means (steps S403, S505 to S518, S1405 to S1415) for determining whether or not to permit the derivation of a plurality of types of winning display results;
Special decision carry-over means (step S913) for carrying over the decision to permit the derivation of the special display result until the special display result is derived based on the decision to permit the derivation of the special display result;
Fluctuation stop control means (steps S405 and S704) for stopping the variable display according to the determination result of the prior determination means and deriving the display result of the variable display device;
When it is determined that the derivation of the special display result is permitted, and when a predetermined condition is established in a state where it is not determined that the derivation of the special display result is permitted, a continuous effect over a plurality of games Continuous production determining means for determining to execute a continuous production that continues during the period (step S1108 is modified to determine whether or not RT, S1110, S1111);
When it is determined by the continuous effect determining means that the continuous effect is to be executed, the continuous effect is continuously executed during the continuous effect period, and the special display result is derived when the continuous effect determining means is determined. Continuous effect execution means (step S1202 (NO) → S1206, S1308, S1316) for informing the information indicating whether or not the permission is determined by the continuous effect;
When the predetermined condition is satisfied in a state where it is not determined that the derivation of the special display result is permitted, the special display is performed by the predetermining unit during a continuous performance period based on the satisfaction of the predetermined condition. Special determination determination means (step S1202 (NO) → S1203) for determining whether or not to permit the derivation of the result is determined;
When it is determined by the special determination determining means that it is determined that the derivation of the special display result is permitted, after the continuous effect is ended, during the predetermined additional effect period following the ended continuous effect. Additional production execution means (S1203 (YES) to S1205, S1202 (YES) → S1203 (YES) → S1203 (YES)) in which additional production is executed and information indicating that permission for deriving the special display result has been determined S1207 (YES) → S1208, S1308),
A plurality of types in which probabilities that the derivation of the winning display result is allowed to be determined by the predetermining means based on the operation of predetermined setting operation means (setting key switch 92, setting switch 91) are different for each set value. Setting value setting means (steps S201 to S210) for selecting and setting any one of the setting values (setting values),
Data storage means (RAM 112) for storing data for controlling the progress of the game including setting value data indicating the setting values set by the setting value setting means so as to be readable and writable;
The progress of the game held by the holding means without individually determining whether or not the set value data of the data for controlling the progress of the game is appropriate when the slot machine is powered on Stored data determination means (steps S104 and S105) for determining whether or not the data for controlling the data matches the data before power-off,
A first step of disabling the progress of the game when it is determined by the stored data determination means that the data for controlling the progress of the game held by the holding means does not match the data before the power-off. Disabling means (step S106 (NO), step S301),
The set value data is read from the data storage means every time a game start operation is performed, and the set value indicated by the read set value data is within a set value range that can be set by the set value setting means The setting value determination means for determining that the read setting value data is appropriate and determining that the read setting value data is not appropriate when the setting value data is not within the range of the settable setting value (steps S501, S502, S1401, S1402),
A second disabling unit that disables the progress of the game when the set value determining unit determines that the read set value data is not appropriate (steps S502 (NO), S1402 (NO), and step S301). )When,
Based on the operation of the setting operation means, even when the progress of the game is disabled by the first disabling means and also when the progress of the game is disabled by the second disabling means. On the condition that the set value is newly set by the set value setting means, the disabled state cancellation means for canceling the state where the progress of the game is disabled and enabling the progress of the game (step S111, FIG. 11)
The pre-determining unit makes a determination in the game with a probability according to the setting value indicated by the read setting value data when the setting value determining unit determines that the read setting value data is appropriate. It is characterized by that.

  In the slot machine, the continuous effect is executed both when it is determined that the derivation of the special display result is permitted. In the continuous performance when it is not determined to allow the derivation of the special display result, information indicating that the permission to derive the special display result is not determined is notified. By the way, there is a case where it is determined that the derivation of the special display result is newly permitted during the execution of the continuous production started when it is not determined that the derivation of the special display result is permitted. Since the continuous performance performed here is started when it is not determined that the derivation of the special display result is permitted, the continuation performance is determined to permit the derivation of the special display result. Information indicating that it is not present is once notified. However, in this case, the additional effect is executed following the continuous effect, and information indicating that the permission for deriving the special display result is determined by the additional effect is notified.

  Thus, even if it is determined that the derivation of the special display result is newly permitted during the execution of the continuous effect, the continuous effect being executed may be executed as it is without changing the control. Not complicated. On the other hand, information indicating the decision to allow the derivation of the special display result after the start of the continuous effect is notified in the additional effect performed following the continuous effect. For this reason, since the player is not given information different from whether or not it is determined that the derivation of the special display result is permitted at the end of the continuous performance, the player feels distrust. I will not let you.

  Note that, for example, after performing the suggestion effect suggesting whether or not the derivation of the special display result is determined, the continuous effect is determined whether or not the derivation of the special display result is determined. Information to be shown can be confirmed and notified at the end of the continuous performance period. The suggestion effect and the confirmation notification may be performed as a series of continuous effect processing, or may be performed as a separate notification after the suggestion effect processing ends. The same applies to the additional effects.

  In addition, the additional effect executing means may execute an additional effect following the continuous effect when a predetermined process is performed after the continuous effect is completed. Even if the predetermined processing is performed based on the player's operation (setting of the bet number by BET operation, operation of the start lever, operation of the stop button, etc.), it is automatically performed (replay winning) It may be automatic setting of the number of bets to be made later). An additional effect following the continuous effect can be executed in response to the start of a new game after the end of the continuous effect.

Further, conventionally, the state of progress of the game by the data stored in the data storage means (RAM) was broken becomes impossible in the slot machine, initialization data in the data storage means by a predetermined reset operation It was released after being released, and the progress of the game was resumed. Here, when the data in the data storage means is initialized by the reset operation, the default setting value (usually, the setting value with the lowest probability that it is determined that the derivation of the winning display result is permitted) is automatically set. Was to be selected. For this reason, the pre-determining means may not be determined with the probability that the amusement store has intended. Especially when the setting value with the lowest probability is automatically selected, it is disadvantageous for the player. There was a problem that would become larger.

On the other hand, when the data stored in the data storage means does not match the data before the power is turned off , the game cannot be progressed properly because the game cannot be progressed properly. It is necessary to initialize the data stored in the data storage means in order to cancel the state where the progress of the game is impossible here. In this case, the data indicating the set value is also initialized. End up. However, in the slot machine, the state in which the progress of the game is disabled based on the fact that the data stored in the data storage means does not match the data before the power is shut off is a new setting value based on the operation of the setting operation means. If it is not set, it will not be released. For this reason, since it is ensured that the game is played based on the newly set value , the fairness of the game can be achieved.

Further, when the determination is made by the prior determination means, the setting value stored in the data storage means is read to determine whether the setting value is within an appropriate range . If the set value is not within an appropriate range, the game cannot be progressed properly because the game cannot be progressed properly. Here, the state where the progress of the game is disabled based on the fact that the setting value indicated by the setting value data stored in the data storage means is not within the proper range is newly set based on the operation of the setting operation means. If the value is not set, it will not be released. For this reason, since it is ensured that the game is played based on the newly set value , the fairness of the game can be achieved.

  FIG. 3 is a diagram showing the configuration of the control circuit of the slot machine 1. As shown in the figure, the control circuit of the slot machine 1 includes a power supply board 100, a game control board 101, an effect control board 102, a reel relay board 103, a reel lamp relay board 104, an external output board 105, and an effect relay board 106. It is divided roughly.

  The power supply board 100 transforms an external power supply voltage of AC 100V and supplies operating power to the game control board 101 and other parts of the slot machine 1. In FIG. 3, it is shown that only the game control board 101, the hopper 80, and each of the switches 91 to 94 are connected, but the power supply board 100 also supplies power to other parts. The power supply board 100 is provided in the slot machine 1 and is connected to a hopper 80 that includes a hopper motor 82 that performs a medal payout operation and a payout sensor 81 that detects a medal payout operation.

  The power supply board 100 sets a winning probability for an internal lottery to be described later, and a setting switch 91 and a setting switch 91 for changing setting values (setting 1 to setting 6) of medal payout rates calculated based on the probability. Are connected to a setting key switch 92 for enabling the operation, a second reset switch 93 for resetting the internal state (RAM 112), and a main switch 94 for switching the power ON / OFF, and detection of these switches. A signal is sent to the game control board 101. These switches 91 to 94 are provided inside the slot machine 1.

  The game control board 101 is a control board on the main side that controls the overall flow of the game in the slot machine 1, and includes a control unit 110 including a CPU 111, a RAM 112, a ROM 113, and an I / O port 114. It is installed. Further, a random number generation circuit 115, a sampling circuit 116, a power supply monitoring circuit 117, a reset circuit 118, and other circuits are mounted.

  The CPU 111 has an interrupt function (including an interrupt prohibition function) such as a timekeeping function and a timer interrupt, and executes a program (described later) stored in the ROM 113 to perform processing related to the progress of the game, and in the slot machine 1 Control each part of the control circuit directly or indirectly. One word of data handled by the CPU 111 is 8 bits (1 byte), and the addresses of the RAM 112 and the ROM 113 are also assigned in units of 8 bits.

  The RAM 112 is used as a work area when the CPU 111 executes a program. The ROM 113 stores programs executed by the CPU 111 and fixed data. The allocation of the addresses of the RAM 112 and the ROM 113 is different between the development model in the manufacturer and the mass production model delivered to the hall. The I / O port 114 inputs and outputs control signals to and from each circuit connected to the game control board 101.

  The RAM 112 uses a DRAM (Dynamic RAM), and requires a refresh operation to maintain the stored data contents. The CPU 111 is provided with a refresh register for performing this refresh operation. The refresh register is composed of 8 bits, which is the size of one word, and the lower 7 bits are automatically incremented every time the CPU 111 fetches an instruction from the ROM 113, and the value is updated by 1 instruction. It is performed at every execution time. The configuration of the RAM 112 area will be described later.

  The random number generation circuit 115 is configured by a counter that counts up and updates the value every time a predetermined number of pulses are generated, as will be described later, and the sampling circuit 116 acquires the numerical value counted by the random number generation circuit 115. . The random number generation circuit 115 is provided for each type of random number used for the progress of the game, and a range of numerical values to be counted for each type of random number is determined. The CPU 111 sends an instruction to the sampling circuit 116 according to the processing to acquire the numerical value indicated by the random number generation circuit 115 as a random number (hereinafter, this function is referred to as a hardware random number function). As a random number for internal lottery described later, a numerical value obtained by processing a numerical value extracted by the hardware random number function by software is used.

  The power monitoring circuit 117 monitors the power supply voltage supplied from the power supply substrate 100, and outputs a voltage drop signal to the control unit 110 when detecting a voltage drop. Although not particularly shown, the control unit 110 includes an interrupt input terminal connected to the power supply monitoring circuit 117, and an external interrupt is generated in the CPU 111 when a voltage drop signal is input to the interrupt input terminal. The CPU 111 executes a power interruption interrupt process.

  The reset circuit 118 outputs a reset signal when the voltage rises to a level at which the control unit 110 can be activated when the power is turned on to start the control unit 110, and generates a signal periodically output from the control unit 110. When the count is incremented without being cleared based on the reset counter, that is, when the control unit 110 does not operate for a certain time, a reset signal is output to the control unit 110 and the control unit 110 is restarted. .

  The CPU 111 also has a function of updating the numerical value of the specific address in the RAM 112 by timer interrupt processing and acquiring the updated numerical value as a random number (hereinafter, this function is referred to as a software random number function). The CPU 111 transmits various commands to the effect control board 102 via the I / O port 114. Each of these commands consists of 8 bits. Note that information (commands) is sent from the game control board 101 to the effect control board 102 only in one direction, and no information (commands) is sent from the effect control board 102 to the game control board 101.

  Connected to the game control board 101 are a single BET switch 45, a MAXBET switch 46, a start switch 41, stop switches 42L, 42C, 42R, a settlement switch 47, a first reset switch 48, and a throw-in medal sensor 44. Detection signals from the switches / sensors are input. In addition, detection signals of the reel sensors 3SL, 3SC, and 3SR are input via the reel relay substrate 103. In accordance with the detection signals of these switches / sensors input via the I / O port 114 or the detection signals of various switches input via the power supply board 100 as described above, the CPU 111 on the game control board 101 Processing is in progress.

  The game control board 101 also includes a flow path switching solenoid 49, a game number display 51, a credit display 52, a payout display 53, a loading instruction lamp 59, a single betting lamp 54, two betting lamps 55, 56, Three betting lamps 57 and 58, a game over lamp 63, a start lamp 60, a replay lamp 62, BET button lamps 70a and 70b, and operation valid lamps 63L, 63C, and 63R are connected, and the CPU 111 follows the progress of the game. These operations are controlled.

  The game control board 101 is connected to reel motors 3ML, 3MC, and 3MR via a reel relay board 103. The CPU 111 controls the reel motors 3ML, 3MC, 3MR via the reel relay substrate 103 and stops the reels 3L, 3C, 3R with reference to a winning flag set in the RAM 112 by an internal lottery described later. An effect control board 102 is further connected to the game control board 101 via an effect relay board 106.

  The effect relay board 106 is a board provided to ensure one-way information transmitted from the game control board 101 to the effect control board 102. The effect relay board 106 does not check the game control board 101 and the effect control board 102 by checking this state, and an illegal signal (especially an external input to the effect control board 102 is input to the control unit 110 of the game control board 101). It is possible to check whether or not a modification has been made such that a signal is input).

  The effect control board 102 is a sub-side control board that controls the execution of effects in the slot machine 1, and is equipped with a control unit 120 including a one-chip microcomputer including a CPU 121, a RAM 122, a ROM 123, and an I / O port 124. Yes. In addition, the random number generation circuit 125 and the sampling circuit 126 are mounted, and the CPU 121 obtains the value counted by the random number generation circuit 125 by the sampling circuit 126, so that the hardware random number function similar to that of the game control board 101 is obtained. Is forming. It also has a software random number function by interrupt processing.

  The CPU 121 executes a program (described later) stored in the ROM 123 to perform processing related to the execution of the effect, and controls each circuit in the effect control board 102 and each circuit connected thereto. The performance is performed based on a command received from the game control board 101 via the I / O port 124. The RAM 122 is used as a work area when the CPU 121 executes a program. The ROM 123 stores programs executed by the CPU 121 and fixed data. The I / O port 124 inputs and outputs control signals to and from each circuit connected to the effect control board 102.

  The effect control board 102 is connected with game effect lamps 75A to 75M, a liquid crystal display 4, speakers 7L, 7R, and 7U, a fluorescent lamp 6, a weight lamp 61, and a bonus notification lamp 66. A reel lamp 3LP is connected via a reel lamp relay substrate 104. The control unit 120 of the effect control board 102 performs these effects by controlling these parts.

  The reel relay board 103 relays between the game control board 101, the external output board 105 and the reel unit 3. The reel relay substrate 103 is also connected with a full sensor 90, and its detection signal is input. The full tank sensor 90 is provided inside the slot machine 1 and detects that the medals in the overflow tank storing the medals overflowed from the hopper 80 are full.

  The reel lamp relay board 104 relays between the effect control board 102 and the reel unit 3. The external output board 105 is connected to an external device such as a hall management computer, and receives a big bonus medium signal, a regular bonus medium signal, a medal IN signal, and the like input from the game control board 101 via the reel relay board 103. The medal OUT signal is output to the external device. In addition, a winning status signal, a reel control signal, and a stop switch signal may be output to an external device.

  Next, the configuration of the RAM 112 of the game control board 101 will be described. FIG. 4 is a diagram showing the configuration of the storage area of the RAM 112. As shown in the figure, the RAM 112 stores an important work 112-1, a general work 112-2, a special work 112-3, a set value work 112-4, a non-saved work 112-5, a stack area 112-6, and a parity storage. A plurality of storage areas including the area 112-7 are provided.

  Among these storage areas, in particular, the set value work 112-4 is an area for storing a set value for determining a winning probability of internal winning to be described later, and the parity storage area 112-7 is a RAM parity at the time of power-off. Is an area for storing An area for setting a winning combination flag to be described later is provided in the general work 112-2. The RAM 112 is supplied with power from a backup power source even in the event of a power failure, and stores stored data.

  In the slot machine 1, 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, a setting value changing operation using the setting switch 91 will be described. In order to change the setting value, it is necessary to turn on the power of the slot machine 1 by the main switch 94 after the setting key switch 92 is turned on. When the slot machine 1 is started without changing the setting value, the setting key switch 92 may be turned off and the power may be turned on by the main switch 94.

  When the setting key switch 92 is turned on and the power is turned on, a setting change mode in which a setting value can be changed is entered. When the setting switch 91 is operated in the setting change mode, the setting value is updated one by one (when further operation is performed from the setting 6, the setting is returned to the setting 1). Then, when the setting key switch 92 is turned OFF after the start lever 11 is operated, the determined setting value after the change is stored in the setting value work 112-4. Then, when the setting key switch 92 is turned off, the state shifts to a state in which the game can proceed.

  When the game can be progressed, the games in the slot machine 1 progress one game at a time, but the set value stored in the set value work 112-4 in the internal lottery performed in each game is within the normal range (1 -6) is determined. When the set value is within the normal range, it is determined that the RAM is abnormal, and a RAM abnormal error code is set and controlled to a RAM abnormal error state to disable the progress of the game.

  Further, when the CPU 111 of the game control board 101 detects the voltage drop signal, the power interruption processing is executed. In the power interruption processing, the RAM parity is calculated based on all data other than the data stored in the parity storage area 112-7 of the RAM 112, and stored in the parity storage area 112-7. ing. Here, the RAM parity is the least significant bit of the sum total of data strings (bits at the same position in each address).

  When the control unit 110 of the game control board 101 is activated, the RAM parity is calculated based on all data other than the data stored in the parity storage area 112-7 among the data stored in the RAM 112. Compared with the RAM parity stored in the parity storage area 112-7. If the comparison results match, the state before power-off is restored based on the state stored in the RAM 112.

  On the other hand, if the comparison result of the RAM parity does not match, it is determined that the RAM is abnormal again, and the RAM abnormal error code is set to control the RAM abnormal error state, thereby making the progress of the game impossible. ing. Unlike the other error states, the RAM abnormal error state is not canceled even if the first reset switch 48 or the second reset switch 93 is operated, and a new set value is set in the setting change mode. It comes to be canceled by this.

  In the slot machine 1, a winning is awarded when the symbols are arranged on the active line set according to the betting number of the variable display device 2. The types of winning combinations are determined according to the gaming status, but can be broadly divided into special roles that involve the transition of gaming status, small roles that involve the payout of medals, and no need to set the number of bets. There is a re-player who can start the next game. In order for each winning 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 for the winning combination.

  FIG. 5A is a diagram showing a winning combination table by gaming state. The winning combination table according to gaming state is stored in advance in the ROM 113 and is used to determine the winning combination determined in the internal lottery. The registered content of the winning combination table according to gaming state depends on the gaming state. In this case, the combination determined as the lottery target is shown. FIG. 5 (a) also shows the symbol combinations corresponding to each combination and the payouts awarded when winning, but these are included in the winning combination table by game state stored in the ROM 113. is not.

  In this slot machine 1, a regular bonus, a big bonus (1), and a big bonus (2) as special roles are combined as small roles, a combination small role, watermelon, bell, and cherry are replayed as replaying roles. ing. In addition, although it is not a target for internal lottery, when a combination of “bell-bell-red 7 / white 7” (RT symbol) is derived at the time of internal winning of a combination small role in a normal gaming state Triggered by this, the gaming state is shifted to RT (Replay Time) only for the subsequent five games. When the regular bonus, the big bonus (1), or the big bonus (2) is won, the gaming state is shifted to RT only during the next five games.

  In a normal gaming state or RT, a regular bonus, a big bonus (1), a big bonus (2), a combination small combination, a watermelon, a bell, a cherry, and a replay are lottery targets. In normal game state replay and RT replay, the number of determination values used for determination of winning is different, so it is defined as a different role in the winning state table by game state, but when each is won The control contents are exactly the same. In addition, in the gaming state of a regular bonus (including a case where the bonus is provided in the big bonus as will be described later), the combination small combination, watermelon, bell, and cherry become the lottery target.

  When the combination of “Red 7-Red 7-Red 7” is aligned on any active line of the variable display device 2, the big bonus (1) is won, and even if it is won in any gaming state (however, the gaming state If the player is in the big bonus or regular bonus, no prize is awarded), and a big bonus that is a game state advantageous to the player is given from the next game as a payout. When the combination of “white 7-white 7-white 7” is arranged on any active line of the variable display device 2, the big bonus (2) is won, and in any gaming state (however, the gaming state If the player is in the big bonus or regular bonus, no prize is awarded), and a big bonus that is a game state advantageous to the player is given from the next game as a payout.

  If the combination of “BAR-BAR-BAR” is aligned on any active line of the variable display device 2, the regular bonus will be awarded, and in any gaming state (however, the gaming state is a big bonus or regular bonus) If it is, the game is not won), and a regular bonus that is a game state advantageous to the player is given as a payout from the next game.

  When the gaming state is a big bonus, the regular bonus gaming state is repeatedly provided until the number of payout medals reaches a predetermined number described later. 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 112, and 1 different from the normal bet number is set to start the game.

  The big bonus ends when the number of payout medals reaches 465. While the gaming state is the big bonus, the big bonus medium flag is set in the RAM 112. If the regular bonus flag is not set at the start of the game when the game state is the big bonus, the regular bonus flag is also set in the RAM 112 at that time.

  If the combination of “Bell-Bell-BAR” is aligned on any active line of the variable display device 2, a winning combination will be awarded, and no matter how many bets (in any game state) are awarded, 15 medals are paid out. If a combination hero is not won at the time of internal winning of the combination hero, a combination of “bell-bell-red 7 / white 7”, that is, an RT symbol may be arranged on any active line of the variable display device 2. . Derivation of the combination of “bell-bell-red 7 / white 7” in the normal gaming state is treated as a substantial RT prize, and the gaming state is shifted to RT. However, even if RT symbols are arranged on the active line, they are not treated as RT prizes when the gaming state is at RT or the regular bonus.

  When the combination of “watermelon-watermelon-watermelon” is aligned on any active line of the variable display device 2, a prize is given to the small part of the watermelon, and a dividend is awarded regardless of the number of bets (in any game state). 15 medals will be paid out. If a combination of “Bell-Bell-Bell” is arranged on any active line of the variable display device 2, it becomes a small prize for Bell, and even if it wins in any number of bets (in any game state) Eight medals are paid out.

  If “cherry” is derived to the left reel 3L in any active line of the variable display device 2, a cherry small prize is awarded, and any number of bets (in any gaming state) Two medals per effective line are paid out as a dividend. Therefore, when “cherry” is derived to the upper or lower stage of the left reel 3L, two effective lines are set to the upper or lower stage, so that four medals are paid out and “cherry” is set to the middle stage. ”Is derived, only one medal line is set in the middle stage, so two medals are paid out.

  If a combination of “JAC-JAC-JAC” is aligned on any active line of the variable display device 2, a replay win will be awarded, and in any gaming state (however, the gaming state will be either a big bonus or a regular bonus) If there is a crab, no win is awarded), and a replay that can be performed without setting the number of bets on the next game is awarded as a payout.

  By the way, when the combination small part is won in the normal gaming state, if the RT symbols are aligned on the active line of the variable display device 2, it is treated as an RT winning and the gaming state is controlled by RT. It was. When the gaming state is RT or a regular bonus, it is not treated as an RT prize, but an RT symbol may be derived if a combination small combination is won. As described above, the RT symbol is a display result derived on the condition that the combination winning combination is won separately from whether or not the RT symbol is treated.

  In addition, even if the RT symbol is not selected as a combination small role, these symbols are displayed in the state that either the regular bonus, the big bonus (1) or the big bonus (2) is set. When a winning combination is not won, it may be derived on the active line of the variable display device 2. That is, when the winning flag of any one of the regular bonus, the big bonus (1), and the big bonus (2) is set, the RT symbol may be derived as a reach.

  Hereinafter, the internal lottery will be described. The internal lottery is to determine whether or not the winning of each of the above combinations is permitted before the display result of the variable display device 2 is derived and displayed (actually, when the start lever 11 is operated). . In the internal lottery, a random number for internal lottery (an integer from 0 to 65535) is acquired from the random number generation circuit 115. Then, for each combination determined according to the gaming state, the acquired random number for internal lottery, the number of bets set by the player, and each combination determined according to the set value set by the setting switch 91 This is performed according to the number of judgment values.

  Reference of the combination according to the gaming state is performed according to the winning combination table according to gaming state shown in FIG. In the winning combination table by gaming state shown in FIG. 5 (a), regular bonus, big bonus (1), big bonus (2), combination small combination, watermelon, bell, cherry, and replay (normal) are eligible for internal lottery. Are read in order. When the gaming state is in RT, the reciprocal (RT) instead of replay (normal) is read out as an internal lottery target combination in the same manner as in the normal gaming state, and the internal lottery target combination is sequentially read out. When the gaming state is a regular bonus (including a case where the bonus is provided during a big bonus), a combination small combination, watermelon, bell, cherry, and JAC are sequentially read out as target combinations for internal lottery.

  In the normal gaming state or RT, the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is set in the game before the previous time, and the game is carried over without winning based on the flag. When the game is played, the regular bonus, the big bonus (1), and the big bonus (2) are not subject to the internal lottery even if they are read from the winning combination table according to gaming state.

  In the internal lottery, the number of judgment values determined for the target part of the internal lottery is sequentially added to the random number for the internal lottery, and when the result of the addition overflows, it is determined that the target part is won. Is done. If the winning combination is determined, the winning flag of the combination is set in the RAM 112. The number of determination values is read in accordance with the storage address of the number of determination values registered in the role table stored in advance in the ROM 113. FIG. 5B is a diagram illustrating an example of the role-specific table. The number of determination values may be 256 or more, and cannot be stored for one word. Therefore, each determination value number is registered using a storage area for two words.

  The number of determination values of the combination to be a lottery target is registered corresponding to the number of bets (BET) set by the player in the game for each combination. This is because even if the winning combinations are the same, the winning probability in the regular bonus may be different from the winning probabilities in other gaming states. In addition, the number of determination values according to the number of bets of the combination to be a lottery object may be common regardless of the set value, and 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”).

  The regular bonus, the big bonus (1), and the big bonus (2) are subject to internal lottery in the normal gaming state or RT, and the storage address of the number of determination values corresponding to the betting number 3 in the normal gaming state and RT is stored. It is registered. The value of the common flag for these roles is 0, and the storage addresses for the number of determination values are individually registered according to the set value.

  Combined small roles, watermelons, bells and cherries are subject to internal lottery in any gaming state, the storage address of the number of judgment values corresponding to the regular bet number 1 in the regular bonus, the number of bets in the normal gaming state and RT A storage address of the number of determination values corresponding to 3 is registered. Among these roles, the value of the common flag of the bell is 0, and the storage address of the determination value number is individually registered according to the set value corresponding to the number of bets. The value of the common flag for roles other than the bell is 1, and a storage address for the common number of determination values is registered regardless of the set value.

  The replay is subject to internal lottery in the normal gaming state or RT, but the storage address of the judgment value number is set to 3 bets in each gaming state as a separate lottery target in the normal gaming state and RT. Correspondingly registered. For both the replay in the normal gaming state and the replay in RT, the common flag is 1, and a common storage address for the number of determination values is registered regardless of the set value.

  FIG. 6 is a diagram illustrating a storage area for the number of determination values acquired based on the addresses registered in the role-specific table. The storage area for the number of determination values is provided in the RAM 112 for the development model and in the address area allocated to the ROM 113 for the mass production model.

  For example, the addresses ADD + 0, ADD + 2, ADD + 4, ADD + 6, ADD + 8, and ADD + 10 are addresses that are referenced when the internal lottery target is a regular bonus, the number of bets is 3, and the set value is 1-6. As for the regular bonus, the number of judgment values is individually stored according to the set value, but since the same number of judgment values (44) is stored for any set value, the regular bonus regardless of the set value. The winning probabilities are the same.

  Addresses ADD + 12, ADD + 14, ADD + 16, ADD + 18, ADD + 20, and ADD + 22 are addresses that are referenced when the internal lottery target is a big bonus (1), the number of bets is 3, and the set value is 1-6. For the big bonus (1), the number of determination values is individually stored according to the set value, and different determination value numbers are stored, so that the winning probability of the big bonus (1) varies depending on the set value. It becomes.

  Addresses ADD + 24, ADD + 26, ADD + 28, ADD + 30, ADD + 32, and ADD + 34 are addresses that are referenced when the internal lottery target is a big bonus (2), the number of bets is 3, and the set value is 1-6. For the big bonus (2), the number of determination values is individually stored according to the set value, and different determination value numbers are stored, so that the winning probability of the big bonus (2) is different according to the set value. It becomes.

  The address ADD + 36 is an address that is referred to regardless of the set value when the betting number is 3, that is, when the target combination of the internal lottery is a combination small combination in the normal gaming state or RT. The address ADD + 38 is an address that is referred to regardless of the set value when the number of bets is 1, that is, in the regular bonus, when the target combination of internal lottery is a combination small combination. The number of judgment values for the combination small combination is registered according to the number of bets, but since different values are registered, when the gaming state is in the regular bonus, when in the normal gaming state or RT Thus, the winning probabilities of the combination small roles will be different.

  The address ADD + 40 is an address that is referred to regardless of the set value when the number of bets is 3, that is, in the normal gaming state or in the RT, when the target combination of the internal lottery is a watermelon. The address ADD + 42 is an address that is referred to regardless of the set value when the bet number is 1, that is, in the regular bonus, when the target part of the internal lottery is a watermelon. The number of determination values for watermelon is registered according to the number of bets, but since the same value is registered, the winning probability of watermelon is the same in any gaming state.

  Addresses ADD + 44, ADD + 46, ADD + 48, ADD + 50, ADD + 52, and ADD + 54 are referred to when the bet number is 3, that is, when the target lot of the internal lottery is bell and the set value is 1 to 6 in the normal gaming state or RT Address. Addresses ADD + 56, ADD + 58, ADD + 60, ADD + 62, ADD + 64, and ADD + 66 are addresses that are referenced when the bet number is 1, that is, when the target character of the internal lottery is a bell and the set value is 1 to 6 in the regular bonus It is. Regarding the bell, since the number of determination values is individually stored according to the gaming state and the set value, and the number of different determination values is stored, the winning probabilities are different according to the gaming state and the setting value.

  The address ADD + 68 is an address that is referred to regardless of the set value when the betting number is 3, that is, when the target character of the internal lottery is cherry in the normal gaming state or RT. The address ADD + 70 is an address that is referred to regardless of the set value when the bet number is 1, that is, when the target character of the internal lottery is cherry in the regular bonus. The number of determination values for cherry is registered according to the number of bets, but since the same value is registered, the winning probability of cherry is the same in any gaming state.

  The addresses ADD + 72 and ADD + 74 are addresses that are referred to regardless of the set value when the bet number is 3 in the normal replay and the bet number is 3 in the replay at the RT, regardless of the set value. , 8980 and 50608 are acquired as the number of determination values, respectively.

  For a combination determined to be won in the internal lottery, a winning flag for the combination is set in the RAM 112. The regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag set in the normal gaming state or RT is carried over after the next game if no winning is generated based on them. It will be a thing. In other cases, the winning flags for each combination are deleted only for the game.

  In addition, even if the regular bonus winning flag, big bonus (1) winning flag, or big bonus (2) winning flag is carried over in the normal gaming state or RT, the lottery and replay lottery will be performed. When winning the replay, the regular bonus winning flag, the big bonus (1) winning flag, the big bonus (2) winning flag, and the winning combination of the small role or the replay are set in an overlapping manner.

  Next, acquisition of random numbers for internal lottery will be described in detail with reference to FIGS. The random numbers for the internal lottery are acquired by extracting random numbers from the random number generation circuit 115 by the hardware random number function and processing them by software by the CPU 111. When acquiring a random number for internal lottery, a random number for determining notification for determining whether or not to turn on the bonus notification lamp 66 is also acquired. The least significant bit of the random number generated by the random number generation circuit 115 is referred to as the 0th bit, and the most significant bit is referred to as the 15th bit.

  FIG. 7 is a block diagram showing the configuration of the random number generation circuit 115 in detail. As shown in the figure, the random number generation circuit 115 includes a pulse generation circuit 115a, a lower counter 115b, and an upper counter 115c. The lower counter 115b and the upper counter 115c are both 8-bit (1 byte) counters, the lower counter 115b is the 0th bit to the 7th bit, and the upper counter 115c is a total of 16 bits from the 8th bit to the 15th bit. The data signal is output.

  The pulse generation circuit 115a outputs a pulse signal at a frequency that is higher than the frequency of the operation clock of the CPU 111 and is not an integral multiple thereof (preferably relatively prime). The pulse signal output from the pulse generation circuit 115a is clocked into the lower counter 115b.

  The lower counter 115b alternately inverts the 0th bit data signal between the H level and the L level every time a pulse signal is input from the pulse generation circuit 115a. Assuming that positive logic is applied, a logical value of H level corresponds to 1 and a logical value of L level corresponds to 0. In the case of negative logic, a logic value of 1 may be read as L level, and a logic value of 0 may be read as H level. When the level of the 0th bit data signal is inverted from H level to L level, that is, whenever the logic value of the 0th bit data signal changes from 1 to 0, the level of the 1st bit data signal is changed to H level. Inverted alternately with L level.

  Similarly, when the level of the (m−1) th bit data signal is inverted from the H level to the L level, that is, whenever the logic value of the (m−1) th bit data signal changes from 1 to 0, the mth bit data The signal level is alternately inverted between the H level and the L level. The carry signal is output every time the level of the seventh bit data signal changes from H level, that is, the logical value of the seventh bit data signal changes from 1 to 0. The carry signal output from the lower counter 115b is clocked into the upper counter 115c.

  The upper counter 115c alternately inverts the eighth bit data signal between the H level and the L level every time a carry signal is input from the lower counter 115b. Each time the level of the 9th bit data signal is inverted from H level to L level, the level of the 9th bit data signal is alternately inverted between H level and L level. Similarly, every time the level of the m−1th bit data signal is inverted from the H level to the L level, the level of the mth bit data signal is alternately inverted between the H level and the L level.

  The logic value of the 16-bit data signal in which the data signal of the lower counter 115b is the lower 8 bits and the data signal of the upper counter 115c is the upper 8 bits is 0 (0000h) every time the pulse generation circuit 115a outputs the pulse signal. ) → 1 (0001h) → 2 (0002h) →... → 65535 (FFFFh) The values are updated so as to be continuous every update, and the maximum value 65535 (FFFFh) is next to the initial value 0 (0000h). The value circulates and is output from the random number generation circuit 115.

  The sampling circuit 116 includes a latch circuit. Based on a sampling command from the CPU 111 (when the start lever 11 is operated), the sampling circuit 116 latches and latches the 16-bit data signal output from the random number generation circuit 115 at that time. Output the data signal. The signal wirings connecting the random number generation circuit 115 and the sampling circuit 116 are connected so that the order of bits is reversed for each of the upper 8 bits and the lower 8 bits. Accordingly, the data latched by the sampling circuit 116 is reverse in the order of bit arrangement for the upper 8 bits and the lower 8 bits with respect to the data signal output by the random number generation circuit 115. For the random number latched by the sampling circuit 116 or the random number processed by the CPU 111, the least significant bit is called the 0th bit and the most significant bit is called the 7th bit for each upper byte and lower byte.

  The CPU 111 fetches numerical data corresponding to the data signal input from the sampling circuit 116 via the I / O port 114 from the sampling circuit 116 separately from the upper 8 bits and the lower 8 bits, and is provided in the RAM 112. Temporarily stored in the random number storage area for internal lottery. The random number storage area for internal lottery is provided for 2 bytes. The upper byte storage area is called the upper area, and the lower byte storage area is called the lower area.

  When the CPU 111 fetches numerical data from the sampling circuit 116, the upper 8 bits of the random number latched by the sampling circuit 116 is taken into the lower area, and the lower 8 bits of the latched random number are taken into the upper area. Therefore, the numerical data taken by the CPU 111 from the sampling circuit 116 into the internal lottery random number storage area is completely in reverse order to the data signal generated by the random number generation circuit 115. Hereinafter, the data signal output from the random number generation circuit 115 will be described as a random number corresponding to the logical value, and the numerical data latched by the sampling circuit 116 will be described as a random number corresponding to the value.

  FIG. 8 is an explanatory diagram until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. As described above, when the random number generated by the random number generation circuit 115 is latched by the sampling circuit 116, the bit order of the latched random numbers is reversed for the upper 8 bits and the lower 8 bits ((a) To (b)).

  The CPU 111 captures the upper 8 bits of the random number latched by the sampling circuit 116 from the upper port into the lower area of the RAM 112 and the lower 8 bits from the lower port into the upper area of the RAM 112 ((b) to (d)). Thus, 16-bit numerical data composed of numerical data taken into the upper area and lower area of the RAM 112 is a random number before processing.

  The data in the lower area is rewritten by the subsequent processing. However, since the data in the lower area of the random number before the processing may be used after that, the data in the lower area before the processing is used as the save data. Save in the save area. Next, the CPU 111 subtracts 11h from the upper area data, and temporarily stores the resulting data in the upper area (e). Next, data in the upper area is read, the data is rotated bit by bit to the lower (right), and the resulting data is temporarily stored in the upper area (f).

  Next, an exclusive OR operation is performed on the upper area data and the lower area data bit by bit, and the resulting data is newly stored in both the upper area and the lower area (g). Further, the saving area data 78h is added, and the resulting data is temporarily stored in the saving area (h). Then, an exclusive OR operation is performed on the upper area data and the save area data for each bit, and the resulting data is newly stored in the upper area (i). At this time, numerical data in which the data stored in the upper area is the upper 8 bits and the data stored in the lower area is the lower 8 bits is acquired as a random number for internal lottery (j).

  Here, the random number for internal lottery finally generated here appears almost randomly every time a pulse signal is input. That is, both continuity and periodicity are eliminated. Here, it is assumed that a state in which values are completely continuous, such as the numerical value of the random number generation circuit 115, approaches a state in which discontinuous values appear randomly. For example, any one of the change from the numerical value of the random number generation circuit 115 to the numerical value of the sampling circuit 116, the change from the numerical value of the sampling circuit 116 to the random number before processing, and the change from the random number before processing to the random number for internal lottery. Corresponds to those whose values vary. The same is true for variations and variations.

  When the winning flag is set in the RAM 112 according to the result of the internal lottery, a winning combination for which the winning flag is set can be made. This is so that when the operation of the stop buttons 12L, 12C, and 12R is detected by the stop switches 42L, 42C, and 42R, the symbols for which the winning flag is set are aligned on the active line of the variable display device 2. The symbol to be stopped on the reel corresponding to the detected stop operation is selected.

  For example, consider a case where the stop buttons 12L, 12C, and 12R are operated in the order of left → middle → right with the regular bonus winning flag set. In the range of the maximum stop delay time of 190 ms from the symbol displayed when the operation of the left stop button 12L is detected, that is, the symbol of “BAR” in any of the upper, middle and lower tiers in the pull-in range of four frames If it can be derived, it is derived to one of the upper, middle and lower stages of the left reels 3L, 3C, 3R. If the symbol of “BAR” is not in the drawing range of 4 frames, it is not derived to the left reel 3L even if the regular bonus winning flag is set.

  A maximum stop delay of 190 milliseconds from the symbol displayed when the operation of the middle stop button 12C is detected in a state where the symbol “BAR” is derived in any of the upper, middle and lower stages of the left reel 3L If the symbol of “BAR” can be derived on the same effective line within the time range, “BAR” is derived to the reel 3C in the middle, and is tempered. When the operation of the right stop button 12R is detected, if the symbol “BAR” can be derived on the same effective line within the range of the maximum stop delay time of 190 milliseconds, “BAR” is derived to the right reel 3R. Make regular bonus awards.

  By the way, when the regular bonus winning flag is set, the operation timing of the stop button 12L for deriving the symbol “BAR” for the left reel 3L is only the timing when the symbols 0 to 6 are positioned in the lower stage. is there. Similarly, when the big bonus (1) winning flag is set, the operation timing of the stop button 12L for deriving the “red 7” symbol for the left reel 3L is the symbol for the 14th to 20th symbols at the bottom. It is only the timing to locate. When the big bonus (2) winning flag is set, the operation timing of the stop button 12L for deriving the symbol “white 7” for the left reel 3L is the timing at which symbols 7 to 13 are positioned in the lower stage Only.

  As described above, the regular bonus, the big bonus (1), and the big bonus (2) are not only set as separate lottery targets in the internal lottery but set as separate winning flags, and each is also awarded a prize. The operation timings of the stop buttons 12L, 12C, and 12R for making them are mutually exclusive.

  In addition, a combination small role winning flag, watermelon winning flag, bell winning flag, cherry winning flag or replay winning flag is set over the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag. When the player is playing, the reels 3L, 3C, and 3R are controlled so as to give priority to the winning of the small role or replay.

  Here, the watermelon, bell, and JAC symbols are arranged at intervals of 5 frames or less in any of the reels 3L, 3C, and 3R, so the watermelon winning flag, the bell winning flag, or the replay winning flag is set. Sometimes, you will always win these roles. Even when the combination small combination winning flag is set, the RT symbol is always derived whether the combination small combination is won. In these cases, even if the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is also set, the regular bonus, big bonus (1) or big bonus (2) is won. Never do.

  In particular, when the gaming state is RT, the player wins the replay with a high probability of 50608/65536 (≈ 1 / 1.29). Furthermore, when combining the combination small roles, watermelons, and bells that are not missed, regular bonuses and big bonuses with a probability of 54759/65536 (≈ 1 / 1.20) to 55022/65536 (≈ 1 / 1.19) or more ( A winning other than 1) or Big Bonus (2) will be won. Therefore, when the gaming state is RT, the regular bonus, big bonus (1) or big bonus (2) even if the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is set. The chances of winning the prize are only 10514/65536 (≈ 1 / 6.23) to 10777/65536 (≈ 1 / 6.08).

  On the other hand, in the normal gaming state, when the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is set, the regular bonus, big bonus (1) or big bonus (2 ) Is a probability of 52142/65536 (≈1 / 1.25) to 52450/65536 (≈1 / 1.25). Therefore, RT is a state in which it is more difficult to win a regular bonus, a big bonus (1) or a big bonus (2) than in a normal gaming state.

  On the game control board 101 side, the internal lottery is performed as described above, and the rotation of the reels 3L, 3C, 3R is stopped according to the result and the operation timing of the stop buttons 12L, 12C, 12R, and a prize is generated. It will be a thing. As a result of winning a prize, a medal is paid out or a game state is transferred as a payout. In this way, depending on the progress of the game on the game control board 101 side, an original effect is performed on the effect control board 102 side. Is called. In order to perform such an effect, the CPU 121 of the effect control board 102 must be able to recognize the progress of the game on the game control board 101 side. Is transmitted from the game control board 101 to the effect control board 102.

  The commands transmitted from the game control board 101 to the effect control board 102 include at least a BET command, an internal winning command, a reel rotation start command, a reel stop command, a winning determination command, and a game state command. The commands transmitted from the game control board 101 to the effect control board 102 include other commands, but since they are not directly related to the present invention, a detailed description thereof is omitted.

  The internal winning command indicates the setting status of the winning flag in the RAM 112 and is transmitted when the start lever 11 is operated and an internal lottery is performed. The reel rotation start command indicates the timing at which the reels 3L, 3C, and 3R start to rotate, and is transmitted when the rotation of the reels 3L, 3C, and 3R is actually started. The reel stop command indicates the number of symbols stopped at the middle and the other of the reels 3L, 3C, and 3R, and is transmitted when the reels 3L, 3C, and 3R are stopped.

  The winning determination command indicates the type of winning generated according to the display result of the variable display device 2 and the number of medals to be paid out with the winning. The display result is derived to the variable display device 2 and the winning determination is made. Sent when done. The gaming state command indicates a gaming state applied in the next game, and is transmitted at the end of one game.

  Next, an effect performed on the effect control board 102 side will be described. In the slot machine 1 according to this embodiment, there are continuous effects and additional effects executed over a plurality of games as effects on the effect control board 102 side. Both the continuous effect and the additional effect are performed by displaying a predetermined image on the liquid crystal display 4. In addition, the effects for each individual game in the continuous effect and the additional effect start when the start lever 11 is operated, and end when all the rotations of the reels 3L, 3C, and 3R are stopped. There are three types of performance results for each game: victory, defeat, and great victory on the player side, but there are many types of performance processes.

  The continuous effect is started when an RT symbol is derived as a display result of the variable display device 2 (regardless of whether or not an RT prize is won). However, even if the RT symbol is derived when the continuous effect or the additional effect is performed, the continuous effect is not newly started here. Before the first game production in the continuous production is started, the start production is performed when the bet number is set in the game, and when the production in the last game in the continuous production is finished, the bonus ( A definite notification is made as to whether or not the winning is a regular bonus, big bonus (1) or big bonus (2).

  The additional effect is performed on the condition that a regular bonus, a big bonus (1), or a big bonus (2) is newly won in the game while the continuous effect is being performed. However, the additional production is not started when the regular bonus, the big bonus (1) or the big bonus (2) is won, but after the continuous production that has been executed at that time is executed to the end, the betting is performed. It starts when the number is set.

  When an additional effect is to be performed, the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is set at the end of the continuous effect. However, at the start of this continuous production, none of the regular bonus, the big bonus (1), and the big bonus (2) are won. Therefore, when an additional effect is to be performed, the result of the loss (regular bonus, big bonus (1) and big bonus (2)) is notified as a result of the continuous effect.

  In the next game in which the result of the loss is notified, the additional effect starts after the effect that the effect is continued is notified. Then, at the time when the last game in the additional production is finished, it is definite that the bonus (which indicates regular bonus, big bonus (1) or big bonus (2)) is won as a result of the additional production. To be notified.

  Regardless of whether it was announced as a result of continuous production or as a result of additional production, if a confirmation notification that a bonus has been won is made, the bet number is set in the next game In addition, the type of bonus that is won at a predetermined rate (regular bonus, big bonus (1) or big bonus (2)) may be notified.

  By the way, there are a plurality of patterns in the above-described continuous effects and additional effects. FIG. 9 is a diagram showing a continuous effect selection table for selecting a pattern of continuous effects and additional effects. There are three types of continuous effect selection tables: a non-winning time table shown in FIG. 9A, a winning time table shown in FIG. 9B, and an additional effect table shown in FIG. 9C. The pattern of the continuous performance is determined by referring to the non-winning time table or the winning time table according to a random number for selecting the continuous performance pattern.

  In the non-winning table shown in FIG. 9 (a), the RT symbol is derived in a state where none of the regular bonus, the big bonus (1), and the big bonus (2) is won (that is, the RT is won). It is a table for selecting the pattern of the continuous production started sometimes. In the winning time table shown in FIG. 9B, the RT symbol is derived in a state where one of the regular bonus, the big bonus (1), or the big bonus (2) is won (that is, the RT symbol as the reach eye). It is a table for selecting the pattern of the continuous production which is started when Regardless of which table the continuous effect pattern is selected, the number of games in which the continuous effect continues is two games or three games.

  In the additional effect table shown in FIG. 9C, when the regular bonus, the big bonus (1), or the big bonus (2) is newly won in the state where the continuous effect has already been performed, the continuous effect is finished. It is a table for selecting the pattern of the additional effect performed after that. The pattern of the additional effect is selected according to the pattern of the continuous effect performed at that time, and the number of games in which the additional effect continues is one game or two games.

  When the final result of the continuous performance is shown, if there are more winning results than the losing result, or if one game shows a big victory result, regular bonus, big bonus (1) Or it means that one of the big bonuses (2) is won. Therefore, such a pattern is a pattern selected according to the winning time table. A pattern where the losing result is not more than the winning result is a pattern selected according to the non-winning table, but when the result of the additional effect that was performed following the continuous effect is shown, the continuous effect If there are more win results than the losing results from the start of the game, or if one game shows a big win result, either regular bonus, big bonus (1) or big bonus (2) It means that you have won the crab.

  In addition, the RAM 122 of the effect control board 102 is provided with a continuous counter indicating the number of remaining games of the continuous effect and an additional counter indicating the number of remaining games of the additional effect, and the initial value according to the selected effect pattern. Is set. In addition, the RAM 122 includes an area for storing the pattern selected for the continuous effect and the additional effect, a confirmation notification flag that is set when the bonus winning is confirmed, and a restart flag for shifting from the continuous effect to the additional effect. An area for setting is provided.

  In addition, a stop symbol table for determining the display mode of the variable display device 2 based on the reel stop command is provided in the RAM 122. However, since the reel stop command includes only the type of the stopped reel and the number of the symbol stopped in the middle as information, it is impossible to determine what symbol is stopped by this alone. Tables indicating all symbols arranged in 3C, 3R are stored in advance, and symbols stopped on the reels 3L, 3C, 3R are registered in the stop symbol table with reference to this table.

  Further, the RAM 122 is also provided with an area for storing the game state applied in the game progressing on the game control board 101 side and the winning status of each combination based on the game state command and the internal lottery command. The game state and the winning situation are to be stored for two games.

  Hereinafter, processing in the slot machine 1 according to this embodiment will be described. In the slot machine 1, the game is progressed by repeatedly performing the game process one game at a time. For this purpose, the game must be in a state where the game can be progressed. In order to be able to advance the game, the setting value of the normal range is stored in the setting value work 112-4 with the control unit 110 including the CPU 111 activated, and the data stored in the RAM 112 is stored in the data stored in the RAM 112. The condition is that there is no abnormality.

  FIG. 10 is a flowchart showing a startup process executed by the CPU 111 of the game control board 101. This activation process is a process performed when the reset signal is input from the reset circuit 118 and the control unit 110 is activated. Since the reset signal is a signal that is output when the power is turned on and when the operation of the control unit 110 is stagnant, the activation process is accompanied by the activation of the control unit 110 that accompanies power-on and a malfunction of the control unit 110. This process is performed when restarting.

  In the startup process, first, the built-in device, peripheral IC, stack pointer, and the like are initialized (step S101), and access to the RAM 112 is permitted (step S102). Then, it is determined whether or not the setting key switch 92 is in an ON state (step S103). If the setting key switch 92 is not ON, the RAM parity is calculated based on all the data stored in the RAM 112 except the parity storage area 112-7 (step S104).

  Next, the RAM parity calculated here is compared with the RAM parity stored in the parity storage area 112-7, that is, the RAM parity calculated and stored at the previous power-off (step S105). Whether or not the data stored in the RAM is normal (step S106). In this embodiment, whether or not the RAM 112 is normal based on the RAM parity is determined only in the startup process.

  If the RAM parities do not match in step S106, the data stored in the RAM 112 is not normal, and the routine proceeds to the RAM abnormality error processing shown in FIG. If the RAM parities match, the data stored in the RAM 112 is normal, so the register stored in the stack area 112-6 is restored (step S107), and the interrupt prohibition is canceled (step S107). S108), the process returns to the state before the power is turned off.

  If the setting key switch 92 is ON in step S103, all the data stored in the RAM 112 is initialized except for the area in use in the stack area 112-6 (other than the setting value work 112-4). Is rewritten to 0 and the set value work 112-4 is rewritten to 0) (step S109), the prohibition of interruption is canceled (step S110), and the process proceeds to the setting change process shown in FIG. 11 (step S111). Then, after the setting change process is completed, the game can be progressed and the process proceeds to the game control process.

  FIG. 11 is a flowchart showing in detail the setting change process executed by the CPU 111 in step S111. In the setting change process, first, a setting changing flag indicating that the setting changing mode is being set is set in a predetermined area of the RAM 112 (step S201), and the setting value (setting change) stored in the setting value work 112-4 is set. Before shifting to the processing, the value of the set value work 112-4 has been rewritten to 1, so it is 1 here) (step S202).

  Thereafter, the operation waits for detection of the operation of the setting switch 91 and the start switch 41 (steps S203 and S204). When the operation of the setting switch 91 is detected in step S203, 1 is added to the setting value read in step S202 (step S205), and whether or not the setting value after the addition is 7, that is, whether the normal range has been exceeded. It is determined whether or not (step S206). If the set value after addition is not 7, the process returns to the state of waiting for detection of the operation of the setting switch 91 and the start switch 41 in steps S203 and S204. If the set value after addition is 7, the set value is corrected to 1 (step S207), and the process returns to the state of waiting for detection of the operation of the setting switch 91 and the start switch 41 in steps S203 and S204.

  When the operation of the start switch 41 is detected in step S204, the changed set value selected at that time is stored in the set value work 112-4 and the set value is confirmed (step S208). Thereafter, the process waits until the setting key switch 92 is turned off (step S209). If it is determined in step S209 that the setting key switch 92 has been turned off, the setting changing flag set in step S201 is cleared (step S210). Then, when returning to the flowchart of FIG. 10, the game can be progressed and the game control process is started.

  FIG. 12 is a flowchart showing in detail the RAM abnormality error process executed by the CPU 111 of the game control board 101. In the RAM abnormality error process, the game number display unit 51 is controlled to display the RAM abnormality error code on the game number display unit 21 (step S301), and then the process proceeds to a loop process in which no process is performed.

  As described above, in the startup process, when the setting key switch 92 is not in the ON state, the data stored in the RAM 112 is compared by comparing the RAM parity calculated at the time of power-off with the RAM parity calculated at the time of startup. It is determined whether or not it is normal, and the routine proceeds to RAM abnormality error processing. In the RAM abnormality error process, since the RAM abnormality error code is displayed on the game number display unit 21, the process proceeds to a loop process in which no process is performed, so that the progress of the game is disabled.

  If the RAM parity does not match, the interrupt is not permitted. Therefore, once the process proceeds to the RAM abnormality error process, the setting key switch 92 is activated in the ON state until the interrupt prohibition is canceled. Even if the power is cut off, no power interruption processing is performed. In other words, since no new RAM parity is calculated and stored in the power interruption process, the RAM parity is always set except when the setting key switch 92 is activated even when the control unit 110 is activated. Since they do not match, the control unit 110 cannot be activated to start (resume) the game.

  Once the RAM abnormal error state is entered, the setting key switch 92 is turned on, the setting key switch 92 is turned on, setting change processing is performed, and a new set value is selected and set by operating the setting switch 91 until the game It becomes impossible to progress. That is, in the state that has shifted to the RAM abnormal error mode state, the state in which the game cannot be progressed is canceled and the game is started (resumed) on condition that a setting value is newly selected and set by operating the setting switch 91. ). In the error state other than the RAM abnormal error, there is no problem of the RAM parity mismatch, so that the state where the game cannot be progressed is canceled only by the operation of the first reset switch 48 or the second reset switch 93, and the game is resumed. Can be made.

  As described above, when the game can be progressed, the game processing is repeated one by one in the slot machine 1. Hereinafter, each game in the slot machine 1 will be described. The “game” in the slot machine 1 is, in a narrow sense, from the operation of the start lever 11 to the stop of the reels 3L, 3C, 3R. Since the bet number before the operation is set, the medals are paid out and the game state is shifted after the reels 3L, 3C, and 3R are stopped, these accompanying processes are also included in the “game” in a broad sense. . It should be noted that the transmission of commands from the game control board 101 to the effect control board 102 will be described only for those necessary for the description of the present invention, and the description of the transmission of other commands will be omitted.

  FIG. 13 is a flowchart showing a game control process performed by the CPU 111 of the game control board 101 for each game. This process is also executed after the power is turned on and a predetermined boot process is performed, or immediately after the setting is changed by operating the setting switch 91. When the process of one game is started, first, an initial process including a process of clearing a predetermined area of the RAM 112 is performed (step S401).

  Next, the number of bets is set by operating one BET button 14 or MAXBET button 15 or by inserting medals from the medal insertion slot 13, and operating the start lever 11 to substantially change the game. BET processing for instructing start is performed (step S402). When the bet number is set by operating the BET buttons 14 and 15 or inserting medals, a BET command is transmitted to the effect control board 102.

  Here, when the gaming state is a regular bonus (including that provided during the big bonus), if the bet number is set to 1 (the bet number larger than this is not set), the start lever 11 is activated. Become. In other game states, the start lever 11 becomes effective after 3 is set as the bet number. Further, if the player has won a replay in the previous game, the same bet number (3 in this embodiment) as the previous game is automatically set by the replay game flag (the replay game flag is erased at this stage). The start lever 11 becomes effective as it is.

  When the number of bets is set by the BET process and the start lever 11 is operated, a random number for internal lottery is extracted, and winning to each combination determined according to the gaming state is allowed based on the extracted random number value A lottery process for determining whether or not to perform is performed (step S403). In the lottery process, an internal winning command indicating the setting status of the winning flag in the RAM 112 is transmitted to the effect control board 102. Details of the lottery process will be described later.

  When the lottery process is completed, a reel fluctuation start process is performed (step S404). In the reel fluctuation start process, the reels 3L, 3C, and 3R in the previous game are processed on the condition that a predetermined time (for example, 4.1 seconds) has elapsed from the start of rotation of the reels 3L, 3C, 3R The motors 3ML, 3MC, and 3MR are driven to start rotation of all the left, middle, and right reels 3L, 3C, and 3R. When starting the rotation of the reels 3L, 3C, 3R, a reel rotation start command is transmitted to the effect control board 102. Thereby, the symbols are variably displayed on the variable display device 2.

  Here, when a predetermined time has not elapsed since the start of rotation in the previous game, the rotation is awaited for rotation, and the weight display unit 31 is notified by lighting the weight lamp 61. Also, the timing of one game timer for the next game is started. Further, when a predetermined condition (detection of the reference position by the reel sensors 3SL, 3SC, 3SR after the rotation speed reaches a constant speed) is satisfied from the start of the rotation of the reels 3L, 3C, 3R, the reel fluctuation stop process is performed. Transition.

  Thereafter, reel fluctuation stop processing is performed (step S405). In the reel fluctuation stop processing, the stop buttons 12L, 12C, and 12R are validated and operated by the player, respectively, and the reel motors 3ML, 3MC, and 3MR are driven and stopped according to the setting state of the winning flag, and the reel 3L The rotation of 3C and 3R is stopped. When the rotation of the reels 3L, 3C, 3R stops, a reel stop command is sent to the effect control board 102. Details of the reel fluctuation stop process will be described later.

  When the driving of each of the reels 3L, 3C, 3R is stopped, in the display mode at the time of stopping, whether any of the above-mentioned role symbols is derived and displayed on the active line according to the bet number set in the BET process in step S402 A winning determination process for determining whether or not is performed (step S406). If it is determined in this winning determination process that a winning combination has been won, various processes corresponding to the winnings generated on the game control board 101 are performed. Here, a winning determination command indicating a winning determination result is sent to the effect control board 102. Details of the winning determination process will be described later.

  When the winning determination process ends, a payout process is performed (step S407). In the payout process, the credit is increased by the number of payouts set in the winning determination process. However, when the number of credits accumulated as data reaches 50, the hopper motor 82 is driven to pay out an excess number of medals from the medal payout slot 71. In addition, various processes that are not related to winning (for example, a process related to the end control of the big bonus and the deletion of a winning flag that does not carry over) are also performed. At the end of the payout process, that is, at the end of one game, a game state command indicating the game state of the next game is sent to the effect control board 102. Details of the payout process will be described later. Then, the process for one game ends, and the process for the next one game starts.

  Next, the lottery process in step S403 will be described in detail. FIG. 14 is a flowchart showing in detail the lottery process executed by the CPU 111 in step S403. In the lottery process, the set value stored in the set value work 112-4 of the RAM 112 is read (step S501), and it is determined whether or not the read set value is in the range of 1 to 6 that is a value that should be originally taken. (Step S502). If the read set value is not in the range of 1 to 6, a RAM abnormality error occurs and the RAM abnormality error process shown in FIG. 12 is performed.

  If the read set value is in the range of 1 to 6, it is determined whether or not the big bonus medium flag is set in the RAM 112 (step S504). If the big bonus medium flag is not set, the process proceeds to step S505 as it is. If the big bonus medium flag is set, the regular bonus medium flag is set in the RAM 112 in any case in order to play the game in the regular bonus game state (step S504). Here, if the regular bonus flag is already set, the state is only continued. Then, the process proceeds to step S505.

  In step S505, random number acquisition processing is performed, and a random number generated by the random number generation circuit 115 is output by the sampling circuit 116 by outputting a sampling command, and the extracted random number is processed into a random number for internal lottery. It is stored in a random number storage area for internal lottery. Details of the random number acquisition process will be described later.

  Next, corresponding to the current gaming state, the lottery target combination registered in the winning combination table according to gaming state in FIG. 5A is sequentially read (step S506). It is determined whether the combination read here is a regular bonus, a big bonus (1), or a big bonus (2) (step S507). If none of the regular bonus, the big bonus (1), and the big bonus (2), the process proceeds to step S509.

  If the regular bonus, the big bonus (1), or the big bonus (2), the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is stored in the RAM 112 in the previous game. It is set and it is determined whether or not these winnings are carried over without occurring (step S508). If the regular bonus winning flag, big bonus (1) winning flag, or big bonus (2) winning flag is set, the process returns to step S506, and the next lottery object registered in the winning combination table according to gaming state Read the role. If none of the regular bonus winning flag, the big bonus (1) winning flag, and the big bonus (2) winning flag are set, the process proceeds to step S509.

  In step S509, the number of BETs set in the current game is read out, and the setting state of the common flag in the combination table in FIG. 5B is acquired corresponding to the BET number read out for the lottery target combination. As a result, it is determined whether or not the common flag is set (step S510).

  If the common flag is set, the number of determination values stored in the address registered in the role-specific table of FIG. 5B is acquired for the read lottery target character corresponding to the BET number (step) S511). Then, the process proceeds to step S513. If the common flag is not set, the setting value set in the RAM 112 is read out and stored in the address registered in the role-specific table corresponding to the BET number and the read setting value for the lottery target role. The number of determination values is acquired (step S512). Then, the process proceeds to step S513.

  In step S513, the number of determination values acquired in step S511 or S512 is added to the internal lottery random value stored in the determination area of the RAM 112, and the result of the addition is used as a new internal lottery random value. Here, it is determined whether or not an overflow has occurred when the number of determination values is added to the value of the random number for internal lottery (step S514).

  If no overflow has occurred, it is determined whether or not there is a combination that is not yet a processing target among the lottery targets in the gaming state (step S515). If there is something that has not been processed yet, the process returns to the process of step S506, and the processing is continued with the next lottery target registered in the winning combination table according to gaming state as the processing target. If there is nothing not to be processed, the process proceeds to step S519.

  If an overflow has occurred, it is determined whether or not the lottery target combination read in the previous step S506 is a regular bonus, a big bonus (1), or a big bonus (2) (step S516). If none of the regular bonus, the big bonus (1), and the big bonus (2), the process proceeds to step S518.

  When the regular bonus, the big bonus (1), or the big bonus (2) is selected, 6 is set as the initial value of the RT counter of the RAM 112. Here, to set 6 as the initial value, the RT counter value is decremented by 1 in step S912 (described later) until the next game is started. This is to secure five games (step S517). Then, the process proceeds to step S518.

  In step S518, the winning flag of the lottery target combination read in the immediately preceding step S506 is set in the RAM 112. Then, the process proceeds to step S519. In step S519, an internal winning command is generated according to the setting status of the winning flag in the RAM 112, and is transmitted to the effect control board 102. Then, the lottery process is terminated, and the process returns to the flowchart of FIG.

  Next, the random number acquisition process in step S505 will be described in detail. FIG. 15 is a flowchart showing in detail the random number acquisition process executed by the CPU 111 in step S505. In the random number acquisition process, first, an interrupt to the CPU 111 is prohibited (step S601).

  Next, the random number generated by the random number generation circuit 115 is latched by the sampling circuit 116 (step S602). Here, in the latched random number, the order of bit arrangement is reversed for each of the upper 8 bits and the lower 8 bits. Then, the CPU 111 captures the lower 8 bits of the random number latched by the sampling circuit 116 into the upper area of the RAM 112 and the upper 8 bits into the lower area. Further, the upper 8 bits of the random number latched by the sampling circuit 116 (that is, the same data as that taken in the lower area) is saved in the save area in the RAM 112 (step S603). That is, the data fetched into the specific area of the RAM 112 by the CPU 111 is completely in reverse order of the bit arrangement from the data generated by the random number generation circuit 115. Then, the interrupt prohibited in step S601 is permitted (step S604).

  Next, the CPU 111 subtracts 11h from the data in the upper area, and temporarily stores the resulting data in the upper area (step S605). Next, the upper area data after the processing of S605 is rotated to the lower bit by bit, and the resulting data is temporarily stored in the upper area (step S606). Next, an exclusive OR operation is performed for each bit on the upper area data and the lower area data after the processing of S606, and the resultant data is newly stored in the upper area (step S607). Here, the processing of the data in the upper area performed before the final exclusive OR operation is completed.

  Further, the upper area data is stored as it is as the lower area data (step S608). Here, the data stored in the lower area is data obtained by performing an exclusive OR operation on the upper area data after the processing of S606 and the lower area data for each bit, and further, until the random number acquisition process is completed. The lower 8 bits of the random number for internal lottery used in the lottery process are not changed.

  Further, 78h is added to the data in the save area, and the resulting data is temporarily stored in the save area (step S609). Then, an exclusive OR operation is performed for each bit of the upper area data after the processing of S606 and the save area data after the processing of S609, and the resulting data is temporarily stored in the upper area (step S610). . Here, the data stored in the upper area is the upper 8 bits of a random number for internal lottery. Then, the random number acquisition process ends, and the process returns to the process of FIG.

  Next, the reel fluctuation stop process in step S405 will be described in detail. FIG. 16 is a flowchart showing in detail the reel fluctuation stop process executed by the CPU 111 in step S405. In the reel fluctuation stop process, first, all the stop buttons 12L, 12C, and 12R are validated (step S701).

  Next, it is determined whether any operation of the stop buttons 12L, 12C, 12R has been detected based on signals from the stop switches 42L, 42C, 42R (step S702). Here, among the stop buttons 12L, 12C, and 12R, those that have been operated and the corresponding reels have stopped rotating are invalid. Therefore, even if a physical operation is performed, the operation is detected. It is determined that it has not been done. If the operation of the stop buttons 12L, 12C, 12R is not detected, the process of step S702 is repeated.

  If any one of the stop buttons 12L, 12C, and 12R is detected, the operation that is determined to be detected among the stop buttons 12L, 12C, and 12R is invalidated (step S703). . Further, the reel stop control process is performed to stop the rotation of the reels 3L, 3C, 3R corresponding to the stop button whose operation is detected (step S704). Here, the symbols to be stopped are selected according to the setting status of the winning flag from among the symbols in the range of 5 frames including the symbols displayed when the stop buttons 12L, 12C, and 12R are operated. It will be.

  Further, a reel stop command indicating the type and stop position of the reel stopped here is generated and transmitted to the effect control board 102 (step S705). Next, it is determined whether or not all the rotations of the reels 3L, 3C, and 3R have been stopped (step S706). If any of the reels 3L, 3C, 3R is still rotating, the process returns to step S702. When all the rotations of the reels 3L, 3C, and 3R are stopped, the reel fluctuation stop processing is ended and the process returns to the flowchart of FIG.

  Next, the winning determination process in step S406 will be described in detail. FIG. 17 is a flowchart showing in detail the winning determination process executed by the CPU 111 in step S406. In the winning determination process, the winning combination corresponding to the gaming state is read in order from the beginning (step S801). Next, it is determined whether or not the symbol combination of the read combination is aligned with any of the five active lines set in the variable display device 2 (step S802).

  If the symbol combination of the combination is complete, a winning flag for the combination is set in the RAM 112 (step S803), and the process proceeds to step S804. If the symbol combination of the combination is not complete, the process proceeds to step S804 as it is. If RT symbols are available in the normal gaming state, the RT winning flag will be set in the RAM 112. However, if the RT symbols are available but in other gaming states, the RT winning flag is set. Never happen.

  In step S804, it is determined whether there is a combination that has not yet been determined as a winning determination among the combinations corresponding to the gaming state. If there is a winning combination that has not yet been determined for winning, the process returns to step S801, and the next winning combination corresponding to the gaming state is read out.

  If all of the combinations corresponding to the game state are targeted for winning determination, it is next determined whether or not a replay winning is made based on whether or not a replay winning flag is set in the RAM 112 (step S805). If a replay prize has been won, a replay game in-progress flag is set in the RAM 112 (step S806). The replay game in-progress flag is deleted when the bet number is automatically set in the next game. Then, the process proceeds to step S815.

  If no replay winning is made, it is determined whether or not the big bonus (1) is won according to whether or not the big bonus (1) winning flag is set in the RAM 112 (step S807). If the big bonus (1) has been won, the big bonus medium flag is set in the RAM 112 and the big bonus (1) winning flag set in the RAM 112 is erased. Further, the RT counter value of the RAM 112 is initialized to 0 (step S808). Then, the process proceeds to step S815.

  If the big bonus (1) has not been won, whether or not the big bonus (2) has been won is determined based on whether or not the big bonus (2) winning flag is set in the RAM 112 (step S809). If the big bonus (2) is won, the big bonus medium flag is set in the RAM 112 and the big bonus (2) winning flag set in the RAM 112 is deleted. Also, the RT counter value in the RAM 112 is initialized to 0 (step S810). Then, the process proceeds to step S815.

  If the big bonus (2) has not been won, whether or not the regular bonus has been won is determined based on whether or not the regular bonus winning flag is set in the RAM 112 (step S811). If the regular bonus is won, the regular bonus medium flag is set in the RAM 112 and the regular bonus winning flag set in the RAM 112 is erased. Further, the RT counter value of the RAM 112 is initialized to 0 (step S812). Then, the process proceeds to step S815.

  If the regular bonus has not been won, it is determined whether or not RT has been won depending on whether or not the RT winning flag is set in the RAM 112 (step S813). If the RT is won, 6 is set as the initial value of the RT counter in the RAM 112. Here, to set 6 as the initial value, the RT counter value is decremented by 1 in step S912 (described later) until the next game is started. This is to secure 5 games (step S814). Then, the process proceeds to step S815. If no RT winning is made, the process proceeds to step S815 as it is.

  In step S815, a winning determination indicating the type of winning combination based on the winning flag set in the RAM 112 (however, in the case of losing, the winning flag is not set) and the number of medals to be paid out with the winning. A command is generated and transmitted to the effect control board 102. Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  Next, the payout process in step S407 described above will be described in detail. FIG. 18 is a flowchart showing in detail the payout process executed by the CPU 111 in step S407. In the payout process, it is determined whether or not there has been a small role winning accompanied by a medal payout depending on whether or not a winning combination flag of combination small combination, watermelon, bell, or cherry is set in the RAM 112 (step S901). If the small role is not won, the process proceeds to step S903 as it is.

  If the small role winning is achieved, the number of medals is sequentially paid out by controlling the hopper 80. However, until the number of credits accumulated as data reaches 50, instead of paying out medals, the number of credits is increased (step S902). Then, the process proceeds to step S903.

  In step S903, whether or not the gaming state of the game is a big bonus is determined based on whether or not the big bonus flag is set in the RAM 112. However, when the big bonus (1) or big bonus (2) winning flag is set in the RAM 112, it is a big bonus (1) winning or a big bonus (2) winning in the game, and the game Since the game state is not a big bonus, even if the big bonus medium flag is set, it is not determined that the big bonus is being performed.

  If it is determined that the big bonus is in progress, the counter provided in the RAM 112 counts the total number of medals paid out after the big bonus starts (step S904). As a result of this count, it is determined whether or not the total number of medals paid out exceeds 465 (step S905). If the total number of medals paid out does not exceed 465, the process proceeds to step S908.

  When the total number of paid-out medals exceeds 465, the big bonus medium flag set in the RAM 112 is erased, and the counter value for counting the total number of paid-out medals is initialized to 0 (step S906). ). Then, the process proceeds to step S910.

  If the game state of the game is not a big bonus, the game state of the game is a regular bonus (not including the case of being offered as a big bonus) depending on whether the regular bonus flag is set in the RAM 112 or not. It is determined whether or not there is (step S907). However, when the regular bonus winning flag is set in the RAM 112, it is a regular bonus winning in the game, and the game state of the game is not a regular bonus. Even if it is set, it is not determined that the regular bonus was in effect. If the game state of the game is a regular bonus, the process proceeds to step S908.

  In step S908, the counter provided in the RAM 112 counts the number of digested games and the number of winning games after the regular bonus starts (in the case of a big bonus, a new regular bonus starts therein). . As a result of this count, it is determined whether the number of winning games in the regular bonus has reached 8 or the number of digested games in the regular bonus has reached 12 (step S909).

  When the number of winning games in the regular bonus is 8 or the number of digested games in the regular bonus is 12, the process proceeds to step S910. If the number of winning games in the regular bonus is not eight and the number of digest games in the regular bonus is not twelve, the process proceeds to step S913. In step S910, the regular bonus flag set in the RAM 112 is erased, and the counter values for counting the number of digest games and the number of winning games in the regular bonus are both initialized to zero. Then, the process proceeds to step S913.

  If the game state of the game is not a regular bonus, it is determined whether the value of the RT counter in the RAM 112 is 0 (step S911). If the value of the RT counter is 0, the process proceeds to step S913 as it is. If the RT counter value is 0, the RT counter value is decremented by 1 (step S912), and the process proceeds to step S913.

  In step S913, if the watermelon winning flag, the bell winning flag, the cherry winning flag, and the replay winning flag are set in the RAM 112, these are deleted. The big bonus (1) winning flag, the big bonus (2) winning flag, and the regular bonus winning flag are not erased here and are carried over to the next game. If a winning flag is set in the RAM 112 in step S803, it is deleted.

  Next, based on the big bonus medium flag and the regular bonus medium flag in the RAM 112, a game state command indicating a game state applied in the next game is generated and transmitted to the effect control board 102 (step S914). Then, the payout process is terminated, and the process returns to the flowchart of FIG. Here, when returning to the flowchart of FIG. 13, the process in the current one game ends.

  In the repetition of the game as described above, the CPU 111 of the game control board 101 shifts the game state among the normal game state, RT, big bonus, and regular bonus, and issues a command according to the progress of the game. It is transmitted to the production control board 102. On the other hand, the CPU 121 of the effect control board 102 performs an original effect including a continuous effect and an additional effect based on the command received from the game control board 101. Hereinafter, the process of the effect performed by the control on the effect control board 102 side will be described.

  FIG. 19 is a flowchart illustrating processing executed by the CPU 121 of the effect control board 102. On the side of the effect control board 102, it is determined whether or not a command sent from the game control board 101 has been received (step S1001). When any command is received from the game control board 101, the type of the received command is determined (step S1002).

  If the type of the received command is the BET command transmitted in step S402, the BET processing described in detail later is performed (step S1003). When the BET process is terminated, the process returns to step S1001.

  If the type of the received command is the internal winning command transmitted in step S519, a start process described in detail later is performed (step S1004). When the start process is completed, the process returns to step S1001.

  If the received command type is the reel rotation start command transmitted in step S404, the information regarding the stop symbols of the reels 3L, 3C, 3R stored in the RAM 122 in the previous game is cleared (step S1005). Then, the process returns to step S1001.

  If the received command type is the reel stop command transmitted in step S705, a reel stop process described in detail later is performed (step S1006). When the reel stop process is terminated, the process returns to step S1001.

  If the received command type is the winning determination command transmitted in step S815, it indicates that the winning determination command has won either the regular bonus, the big bonus (1), or the big bonus (2). It is determined whether or not (step S1007). If it is shown that none of the regular bonus, the big bonus (1), and the big bonus (2) has been won, the process returns to step S1001.

  If it is shown that the regular bonus, the big bonus (1), or the big bonus (2) is won, it is determined whether or not the value of the continuous counter and the value of the additional counter in the RAM 122 are both 0 ( Step S1008). If the value of the continuous counter and the value of the additional counter are both 0, it means that neither a continuous effect nor an additional effect has been performed at this time, and the process directly proceeds to step S1011.

  If at least one of the value of the continuous counter or the value of the additional counter is not 0, the continuous effect or the additional effect is being executed, or these effects can be performed. In this case, first, the continuous effect or additional effect being executed is terminated (step S1009). Further, the value of the continuous counter in the RAM 122 and the value of the additional counter are initialized to 0 (step S1010). Then, the process proceeds to step S1011.

  In step S1011, the liquid crystal display 4, the speakers 7L, 7R, and 7U, the game effect LEDs 75A to 75M, and the like are controlled to perform a predetermined bonus winning effect. This bonus winning effect may have a different form depending on whether the bonus is a regular bonus, a big bonus (1), or a big bonus (2). Then, the process returns to step S1001.

  If the received command type is the gaming state command transmitted in step S914, the gaming state stored in the gaming state storage area of the latest game in the previous game (that is, applied in the current game). The game state is transferred to the game state storage area of the previous game provided in the RAM 122, and the game state indicated by the game state command (that is, the game state applied in the next game) is stored in the RAM 122. The game state is saved in the game state save area (step S1012). Then, the process returns to step S1001.

  If the received command type is another command, processing corresponding to the type of each command (the details are omitted because it is not related to the present invention) is executed (step S1013). Thereafter, the process returns to step S1001.

  Next, the BET processing in step S1003 will be described in detail. FIG. 20 is a flowchart showing in detail the BET processing executed by the CPU 121 in step S1003. In the BET processing, it is determined whether or not a fixed notification flag is set in the RAM 122 (step S1101). If the confirmation notification flag is set, when all the rotations of the reels 3L, 3C, and 3R are stopped in the previous game, the continuous effect or the additional effect is finished and the confirmation of the bonus winning is notified. It will be.

  In this case, a random number for type notification lottery is extracted by the software random number function, and a type notification lottery for determining whether or not to notify the type of bonus won by the extracted random number according to the value is performed (step S1102). Then, it is determined whether or not notification of the bonus type is determined in this type notification lottery (step S1103). If it is determined not to notify the bonus type, the process directly proceeds to step S1105.

  When it is determined that the type of bonus is to be notified, the regular bonus, the big, and the like are displayed by displaying an image on the liquid crystal display 4 according to the winning situation stored in the RAM 122 in the process (described later) of step S1201 of the previous game. It is notified whether the bonus (1) or the big bonus (2) is won (step S1104). Then, the process proceeds to step S1105. In step S1105, the fixed notification flag set in the RAM 122 is deleted. Then, the BET processing is terminated and the process returns to the flowchart of FIG.

  If the confirmation notification flag is not set, it is determined whether or not the value of the continuous counter in the RAM 122 is 0 (step S1106). If the value of the continuous counter is not 0, the continuous effect has already been executed, so the BET processing is terminated as it is, and the flow returns to the flowchart of FIG. If the value of the continuous counter is 0, it is further determined whether or not the value of the additional counter in the RAM 122 is 0 (step S1107).

  If the value of the additional counter is also 0, the RT symbols are aligned on any valid line of the variable display device 2 with reference to the stopped symbols stored in the RAM 122 in the process (described later) of step S1301 of the previous game. It is determined whether or not (step S1108). If there is no RT symbol on any valid line, the BET processing is terminated as it is, and the flow returns to the flowchart of FIG.

  If the RT symbol is aligned on any of the active lines, the regular bonus, the big bonus (1) or the big bonus (2) according to the winning situation stored in the RAM 122 in the process of step S1201 (described later) of the previous game. It is determined whether or not any one has been won (step S1109).

  If one of the regular bonus, big bonus (1) or big bonus (2) is won, a random number for selecting a continuous effect pattern is extracted by the software random number function and stored in the ROM 123 according to the extracted random number value. With reference to the winning time table in the continuous performance selection table, a continuous performance pattern to be started is selected. The continuous effect pattern selected here is stored in the RAM 122 (step S1110). Then, the process proceeds to step S1112.

  If none of the regular bonus, the big bonus (1), and the big bonus (2) is won, a random number for selecting a continuous effect pattern is extracted by the software random number function and stored in the ROM 123 according to the extracted random number value. With reference to the non-winning time table in the continuous performance selection table, a continuous performance pattern to be started is selected. The continuous effect pattern selected here is stored in the RAM 122 (step S1111). Then, the process proceeds to step S1112.

  In step S1112, a value corresponding to the effect pattern selected in step S1110 or step S1111 is set in the continuous counter of the RAM 122 as an initial value. Furthermore, the start effect is performed by displaying a predetermined image indicating the start of the continuous effect on the liquid crystal display 4 (step S1113). Then, the BET processing is terminated and the process returns to the flowchart of FIG.

  If the value of the continuous counter is not 0 in step S1107, it is determined whether a restart flag is set in the RAM 122 (step S1114). If the restart flag is not set, the BET processing is terminated as it is, and the process returns to the flowchart of FIG.

  If the resume flag is set, an additional effect is executed instead of the continuous effect from the current game. Here, the resumption effect is performed by displaying a predetermined image indicating the start of the additional effect (the resumption of the once completed continuous effect) (step S1115). Further, the restart flag set in the RAM 122 is erased (step S1116). Then, the BET processing is terminated and the process returns to the flowchart of FIG.

  Next, the start process in step S1004 will be described in detail. FIG. 21 is a flowchart showing in detail the start process executed by the CPU 121 in step S1004. In the start process, first, the winning situation saved in the storage area for the winning situation of the latest game in the previous game (that is, the setting state of the winning flag in the previous game) of the winning situation of the previous game provided in the RAM 122 is displayed. The storage area is moved to, and the winning situation indicated by the received internal winning command (that is, the setting situation of the winning flag in the current game) is saved in the winning area saving area of the latest game provided in the RAM 122 (step S1201).

  Next, it is determined whether or not the value of the continuous counter in the RAM 122 is 0 (step S1202). If the value of the continuous counter is not 0, the continuous effect has already started or at least the start effect has been performed. In this case, referring to both the current game and the previous game's winning status storage area, it is determined whether or not the regular bonus, the big bonus (1) or the big bonus (2) is won for the first time in the current game. Determination is made (step S1203). If the regular bonus, the big bonus (1) or the big bonus (2) is not won for the first time in this game, the process proceeds to step S1206.

  When the regular bonus, big bonus (1) or big bonus (2) is won for the first time in this game, it is added from the continuous production selection table according to the continuous production pattern stored in the RAM 122. Select a production pattern. The additional effect pattern selected here is also stored in the RAM 122 (step S1204). Further, a value corresponding to the selected effect pattern is set as an initial value in the additional counter of the RAM 122 (step S1205). Then, the process proceeds to step S1206.

  In step S1206, an image corresponding to the pattern of the additional effect stored in the RAM 122 and the value of the continuous counter in the RAM 122 is displayed on the liquid crystal display 4, and the effect for the current game in the series of continuous effects is started. Let Then, the start time process is terminated, and the process returns to the flowchart of FIG.

  If the value of the continuous counter is 0 in step S1202, it is further determined whether or not the value of the additional counter in the RAM 122 is 0 (step S1207). If the value of the additional counter is also 0, the start process is terminated without starting any effect here, and the process returns to the flowchart of FIG.

  If the value of the additional counter is not 0, the pattern of the additional effect stored in the RAM 122 and an image corresponding to the value of the additional counter in the RAM 122 are displayed on the liquid crystal display 4, and this time in the series of additional effects. The production for the game is started (step S1208). If the value of the continuous counter is not 0, the process of step S1208 is not executed even if the value of the additional counter is not 0, so the additional effect is performed after the continuous effect is completed. . Then, the start time process is terminated, and the process returns to the flowchart of FIG.

  Next, the reel stop process in step S1006 will be described in detail. FIG. 22 is a flowchart showing in detail the reel stop process executed by the CPU 121 in step S1006. In the reel stop process, a symbol is specified by referring to the table of the ROM 123 according to the received reel stop command, and the symbol stopped for the reel indicated by the reel stop command is stored in the stop symbol table of the RAM 122 (step S1301).

  Next, with reference to the stop symbol table, it is determined whether or not all the rotations of the reels 3L, 3C, and 3R have stopped (step S1302). If at least one of the reels 3L, 3C, 3R is still rotating, the reel stop process is terminated as it is, and the process returns to the flowchart of FIG.

  When all the rotations of the reels 3L, 3C, and 3R are stopped, it is determined whether or not the value of the continuous counter in the RAM 122 is 0 (step S1303). If the value of the continuous counter is not 0, the continuous effect is being executed at this point, so that an image corresponding to the continuous effect pattern stored in the RAM 122 and the value of the continuous counter is displayed on the liquid crystal display 4. Then, the result of the effect for the current game in the series of continuous effects is notified (step S1304). Then, 1 is subtracted from the value of the continuous counter in the RAM 122 (step S1305).

  Here, it is determined whether or not the value of the continuous counter has become 0 as a result of the subtraction (step S1306). When the value of the continuous counter becomes 0, it is determined whether or not the continuous effect pattern stored in the RAM 122 is a pattern selected based on the winning time table, and is a pattern for informing confirmation of bonus winning. (Step S1307). If it is a pattern for informing confirmation of bonus winning, the process proceeds to step S1315.

  If it is not a pattern for notifying that the bonus has been won, information indicating that the bonus has been lost is displayed on the liquid crystal display 4 to notify the player (step S1308). Next, it is determined whether or not the value of the additional counter in the RAM 122 is 0 (step S1309). If the value of the additional counter is 0, the continuous effect ends without performing the additional effect, so the reel stop process is terminated as it is, and the process returns to the flowchart of FIG. If the value of the additional counter is not 0, an additional effect is performed after the end of the continuous effect, so a restart flag is set in the RAM 122 (step S1310). Then, the reel stop process is terminated, and the process returns to the flowchart of FIG.

  If the value of the continuous counter is 0 in step S1303, it is determined whether or not the value of the additional counter in the RAM 122 is 0 (step S1311). If the value of the additional counter is not 0, the additional effect is being executed at this point, so an image corresponding to the additional effect pattern stored in the RAM 122 and the value of the additional counter is displayed on the liquid crystal display 4. The result of the effect for the current game in the series of additional effects is notified (step S1312). Then, 1 is subtracted from the value of the additional counter in the RAM 122 (step S1313).

  Here, as a result of the subtraction, it is determined whether or not the value of the additional counter has become 0 (step S1314). If the value of the additional counter becomes 0, the process proceeds to step S1315. In step S1315, a fixed notification flag is set in the RAM 122. Further, information indicating that the bonus is won is displayed on the liquid crystal display 4 to notify the player (step S1316). Then, the reel stop process is terminated, and the process returns to the flowchart of FIG.

  If the value of the continuous counter is not 0 in step S1306, the value of the additional counter is 0 in step S1311, or the value of the additional counter is not 0 in step S1314, either However, since the presence / absence of bonus winning is not notified at the time of BET in the next game, the reel stop process is terminated as it is, and the process returns to the flowchart of FIG.

  Hereinafter, a continuous effect and an additional effect performed in the slot machine 1 according to this embodiment will be described based on specific examples. FIG. 23 is a diagram schematically illustrating a specific execution mode of the continuous effect and the additional effect. In this example, when the regular bonus, the big bonus (1) and the big bonus (2) are not won, the RT is won and the continuous production is started. The case where either the big bonus (1) or the big bonus (2) is won will be described as an example. Note that the game winning RT is designated as the 0th game.

  When the RT game is won in the 0th game, the fact that the RT symbol is derived is stored in the stop symbol table of the RAM 122, and the regular bonus, the big bonus (1) and the big bonus (2) are stored in the RAM 122 as the winning status. It is remembered that none of these are won. When the number of bets is set in the first game, the continuous effect pattern is selected according to the non-winning table. Here, assuming that a pattern that continues for three games is selected, 3 is set as the initial value of the continuous counter of the RAM 122.

  In addition, when the bet number is set in the first game, a start effect is performed on the liquid crystal display 4. When the start lever 11 is operated in the first game, the first game of the continuous effect is started on the liquid crystal display 4. When all the rotations of the reels 3L, 3C, and 3R are stopped, the result of one game of continuous effects is displayed on the liquid crystal display 4. At this time, the value of the continuous counter is subtracted to 2.

  When the number of bets is set in the second game, nothing is performed as an effect because the continuous effect is being executed. When the start lever 11 is operated in the second game, the second game of the continuous effect is started on the liquid crystal display 4. At this time, if the big bonus (1) is newly won, an additional effect pattern is selected according to the continuous effect pattern. Here, assuming that a pattern that continues for two games is selected, 3 is set as the initial value of the additional counter in the RAM 122. When all the rotations of the reels 3L, 3C, and 3R are stopped, the result of two games of continuous effects is displayed on the liquid crystal display 4. At this time, the value of the continuous counter is subtracted to 1, but the value of the additional counter remains at 2.

  When the number of bets is set in the third game, nothing is performed as an effect because a continuous effect is being executed. When the start lever 11 is operated in the third game, the third game effect of the continuous effect is started on the liquid crystal display 4. When all the rotations of the reels 3L, 3C, and 3R are stopped, the result of three games of continuous effects is displayed on the liquid crystal display 4. At this time, the value of the continuous counter is subtracted to 0, but the value of the additional counter remains at 2. At this time, since the pattern of the continuous performance is not a pattern for notifying the confirmation of the bonus winning, here, the liquid crystal display 4 is notified of the bonus loss. Since the value of the additional counter is not 0, a restart flag is set in the RAM 122.

  When the number of bets is set in the fourth game, since the restart flag is set in the RAM 122, a restart effect for informing the continuation of the effect is performed on the liquid crystal display 4. When the start lever 11 is operated in the fourth game, the first game effect of the additional effect is started on the liquid crystal display 4. When all the rotations of the reels 3L, 3C, and 3R are stopped, the result of one game of an additional effect is displayed on the liquid crystal display 4. At this time, the value of the additional counter is subtracted to 1.

  When the number of bets is set in the fifth game, nothing is performed as an effect because a continuous effect is being executed. When the start lever 11 is operated in the fifth game, the second game effect of the additional effect is started on the liquid crystal display 4. When all the rotations of the reels 3L, 3C, and 3R are stopped, the result of two games of additional effects is displayed on the liquid crystal display 4. At this time, the value of the additional counter is subtracted to 0. Here, since the value of the additional counter becomes 0, the confirmation of bonus winning is notified on the liquid crystal display 4. In addition, a fixed notification flag is set in the RAM 122.

  When the number of bets is set in the sixth game, since the confirmation notification flag is set in the RAM 122, the type notification lottery is performed. If this type notification lottery is won, the liquid crystal display 4 notifies that the big bonus (1) is won.

  As described above, in the slot machine 1 according to this embodiment, the continuous performance is won when the regular bonus, the big bonus (1), or the big bonus (2) is won. Also done. In the former case, the continuous performance is a content that has not won any of the regular bonus, the big bonus (1) or the big bonus (2), and the regular bonus and the big bonus (1 ) Or Big Bonus (2) is not won, the confirmation of the loss is informed.

  However, in the game after the continuous production in the former case is started, a regular bonus, a big bonus (1), or a big bonus (2) may be newly won. Even in this case, since the continuous production that has already been started is performed to the end, the control related to the execution of the continuous production does not become complicated. However, if only the confirmation of the loss is notified as it is, information different from the winning situation at the end of the continuous performance remains to be shown to the player.

  Therefore, when a regular bonus, a big bonus (1) or a big bonus (2) is newly won in the game after the continuous production is started, it is assumed that the additional production is executed following the continuous production. . This additional effect indicates that the player has won the regular bonus, the big bonus (1), or the big bonus (2). Thereby, the continuous production once started can be performed to the end without causing the player to feel distrust.

  In addition, the continuous production is started when the RT symbol is derived in a state where neither the continuous production nor the additional production has been performed. For this reason, it becomes easy for the player to understand the trigger for starting the continuous performance visually. Further, the RT symbol is derived by missing a combination small part, or is derived as a reach when a regular bonus, a big bonus (1) or a big bonus (2) is won. For this reason, the derivation of the RT symbol before the start of the continuous performance can give the player a sense of expectation for winning the regular bonus, the big bonus (1) or the big bonus (2). Can be improved.

  Here, when the RT symbol is derived as the reach when the regular bonus, the big bonus (1) or the big bonus (2) is won, the gaming state is already controlled to the RT, so the regular state is regular. Even if the bonus, big bonus (1) or big bonus (2) is won, it is difficult to win a prize. When the RT symbol is derived by missing the combination small combination, if the game state is a normal game state, the game state is shifted to RT as a trigger.

  As described above, while the continuous performance is being executed, the gaming state is often controlled to RT, and a prize other than the regular bonus, the big bonus (1), or the big bonus (2) (especially replay) is won. Since there are many cases, the regular bonus, big bonus (1) or big bonus (1) or big bonus (2) will be won, or the losing eyes will be derived, so that the regular bonus, big bonus (1) or There are few cases where the player knows whether or not the big bonus (2) is won. For this reason, while a continuous production continues, it is possible to give the player a sense of expectation in a period longer than one game, and to improve the interest of the game.

  In the continuous production, when the RT symbol is derived, any production pattern is selected from a plurality of predetermined patterns. When a new regular bonus, a big bonus (1) or a big bonus (2) is won during the continuous production, the additional production pattern performed at that time is the continuous production pattern that was being executed at that time. Chosen according to As described above, continuous effects (and additional effects) are performed with a plurality of types of patterns, so that a variety of effects can be achieved and the interest of the game can be improved. In addition, by selecting the pattern of the additional effect according to the pattern of the continuous effect being executed, the additional effect can be matched with the continuous effect, and the continuous effect and the additional effect can be shown to the player as a series of effects without any sense of incongruity. Will be able to.

  Furthermore, as a pattern of continuous effects, there are a pattern that continues for a period of two games and a pattern that continues for a period of three games, and the period during which the continuous effects continue is determined by the selection of the pattern. The additional effect patterns include a pattern that continues during the period of one game and a pattern that continues during the period of two games, and the period during which the additional effect continues is determined by the selection of the pattern. In this way, there are different periods as the period during which the continuous effect and the additional effect are performed, so that the aspect of the effect becomes abundant and the interest of the game can be further improved.

  By the way, in the slot machine 1 according to this embodiment, three types of special bonuses, a regular bonus, a big bonus (1), and a big bonus (2) are prepared as special roles for shifting to a gaming state advantageous to the player. Here, the symbols “BAR”, “Red 7” and “White 7” which are the symbols of the respective roles are arranged at intervals of 7 frames for the left reel 3L, and therefore, a stop button 12L for winning each of them. These operation timings are mutually exclusive. For this reason, even if the confirmation of bonus winning is notified as a result of the continuous performance (and additional performance), the player must select an appropriate operation timing for the operation of the stop button 12L. In this way, the number of game procedures increases and the technical intervention by the player also increases, so that the interest of the game can be improved.

  In addition, when the bonus winning decision is notified as a result of the continuous performance (and additional performance), the type notification lottery is performed, and when this is won, any of the regular bonus, the big bonus (1) or the big bonus (2) is performed. You will be informed even if you win. This notification eliminates the need for the player to try the operation timing corresponding to each of the regular bonus, the big bonus (1), and the big bonus (2), and the regular bonus, the big bonus (1) or the big bonus (2) immediately Will be able to win the game, so that the game can proceed smoothly. In addition, since the notification of the type is not performed if it is lost in the type notification lottery, it is possible to give a player a sense of expectation as to whether or not the type will be further notified after the confirmation of the bonus winning is notified. The interest of the game can be improved.

  As described above, the types of winning combinations that are subject to internal lottery for each gaming state are registered in the winning combination table by gaming state, but the number of judgment values that determine the winning probability of each combination is referred to from the determining table. Stored in the address. For combination small roles, watermelons, bells, and cherries defined as winning combinations in any gaming state in the role-specific table, the storage address of the judgment value number is registered for each bet number. The number of determination values is acquired according to the number (although the same determination value number is acquired as a result for watermelon and cherry).

  Here, the number of bets in the regular bonus is fixed at 1, but the number of bets in the gaming state other than the regular bonus is fixed at 3. As a result, it is possible to perform an internal lottery of a combination small combination, watermelon, bell and cherry with a winning probability corresponding to the gaming state simply by acquiring the number of determination values according to the number of bets. In addition, since it is not necessary to determine the gaming state when acquiring the determination value number, the processing steps in the internal lottery are simplified.

  Moreover, the betting number 1 corresponding to the regular bonus has a higher probability of winning the bell than when the betting number is 3, so that the player's expectation in the regular bonus is further increased and the interest of the game is improved. Can do. The combination small role has a lower probability of winning when the number of bets is 1, but the effect is less than that of increasing the probability of winning the bell, and the effect of making it difficult for RT symbols to be derived in regular bonuses. It has become.

  In addition, the storage address of the judgment value number of each combination registered in the combination table may differ depending on the set value, but the winning probability is the same regardless of the set value. For the winning combination, the number of determination values is stored in common regardless of the set value. By storing the number of determination values in common in this way, the storage capacity required for that is reduced. However, in the role-specific table, even if the target number of the internal lottery is the same as the number of bets set and the address storing the number of judgment values referenced according to the set value is different, it is stored at a different address. In some cases, the number of determination values is the same.

  In general, in the development stage, the simulation is performed while adjusting the number of determination values according to the set values for at least some of the combinations (that is, adjusting the winning probability of internal lottery). As the initial number of determination values, a different number of determination values is registered according to the set value. However, as a result of adjustment by simulation, the number of determination values when the set values are different may be the same. Although the same number of judgment values was registered as the initial number of judgment values according to the set value, the number of judgment values registered from the beginning may be used as it is depending on the result of simulation (result of simulation). The number of judgment values different from the initial value, that is, the number of judgment values may differ depending on the set value). Then, the number of determination values obtained with an appropriate result in the simulation in each case is selected as the number of determination values to be set for the mass production model.

  Here, even if the number of determination values adjusted by the simulation is the same regardless of the set value, the determination value number is stored in the ROM 113 by the same address assignment as the address assignment in the development stage. It can be used as a model for mass production. For this reason, it is not necessary to change the method for storing the number of judgment values in the model for mass production from the model for development, so that development from the initial design stage to the model for mass production can be easily performed. Become.

  In addition, the internal lottery adds the number of judgment values of each role referred from the role-specific table to the acquired random number for internal lottery, and depending on whether or not the result of the addition overflows, Judgment is made on whether or not there is a win. For this reason, an internal lottery can be performed using the number of determination values of each combination as it is. It should be noted that when the winning determination table is generated before the actual winning determination is made, the loop processing is required twice, but according to this embodiment, the loop processing in the lottery processing is only required once. Thus, the processing efficiency in the entire lottery process is high.

  By the way, in the slot machine 1 according to this embodiment, when the number of determination values corresponding to the combination to be selected for the lottery is sequentially added to the random number for internal lottery according to the gaming state, and the result of the addition overflows It is determined that the winning combination has been won. When the internal lottery is performed in this way, the processing efficiency is high, but the determination value as to whether or not each winning combination is won is set in a range in which the value is continuous for each winning combination.

  Here, as a random number for internal lottery, a 2-byte random number value generated by the random number generation circuit 115 is not used as it is. That is, the sampling circuit 116 takes in the random number extracted from the random number generation circuit 115 in the reverse order of the bit order in the upper byte and the lower byte, and further, the upper byte and the lower byte of the 2-byte random number latched by the sampling circuit 116. The bytes are exchanged to be taken into the upper and lower areas. Then, 11h is subtracted from the upper area data, the upper area data is rotated, the upper area data and the lower area data are subjected to an exclusive OR operation for each bit, and the lower area data is rewritten. The rewritten lower region data and upper region data are subjected to an exclusive OR operation for each bit to obtain a random number for internal lottery.

  By the way, since the random number generated by the random number generation circuit 115 is counted up every time the pulse generation circuit 115a generates a pulse signal, the random number generated by the random number generation circuit 115 is used as it is as a random number for internal lottery. In this case, it is continuously determined that the winning combination is the same for several pulse inputs, and the player can hit the target. Further, if the high-order byte and the low-order byte of the random number generated by the random number generation circuit 115 are simply exchanged, the value every time the pulse is generated becomes periodic every 256, so that a certain amount of aiming is still possible. Furthermore, even if the order of bits is changed in reverse order for each byte, it is not possible to eliminate the periodicity of the value every time a pulse signal is generated.

  On the other hand, the random numbers for the internal lottery used in the slot machine 1 of this embodiment are obtained by reversing the order of the random number bits generated by the random number generation circuit 115, and the upper region data and the lower region. Since the exclusive OR operation is performed on the data of, the change in whether the value of each bit becomes 1 or 0 becomes large, and it is sufficient that the value becomes periodic every time a pulse signal is generated. Can be resolved. Thereby, it is possible to avoid the occurrence of the winning period and the easy-to-win period, and to prevent the player from aiming.

  Further, by subtracting 11h from the upper area data before performing the exclusive OR operation and rotating the upper area data, the change in whether each bit value becomes 1 or 0 is greatly increased. The random number value for internal lottery every time a pulse signal is generated is scattered, and the effect of preventing aiming by the player can be enhanced. In addition, since the exclusive OR operation is also performed on the data that is the lower byte in the random number for internal lottery, the random number value for internal lottery for each generation of the pulse signal will be scattered. The effect of preventing hitting by a person can be enhanced.

  Furthermore, the data that is the upper byte in the random number for internal lottery can be obtained by performing an exclusive OR operation on the data of the lower area where the exclusive OR operation circuit has been performed with the upper area data for each bit. It has become. In this way, the lower area data whose values are separated by the first exclusive OR operation can be further separated, and the aiming by the player can be more effectively prevented. .

  Further, in the slot machine 1 according to this embodiment, when an abnormality occurs in the data stored in the RAM 112, it is controlled to the RAM abnormality error state, the progress of the game is disabled, and the setting change mode is set. If the setting value is not newly selected / set based on the setting change operation, the game disabled state is not released. That is, even if an abnormality occurs in the data stored in the RAM 112, the setting value selected and set based on the setting change operation (in general, the setting value) is not set automatically by the slot machine 1. Since the change operation is performed by an employee of the game shop, it is ensured that the game is played based on the setting value selected by the game shop), so that the game can be fair.

  In addition, when determining whether or not to win the winning combination in the internal lottery, the set value stored in the set value work 112-4 must be an appropriate value (a value in the range of 1 to 6). For example, instead of deciding whether or not to win based on a probability based on a default setting value (for example, setting 1), in this case as well, the game is controlled to a RAM abnormal error state and the progress of the game is disabled. If the setting change mode is entered and a new setting value is not selected or set based on the setting change operation, the state where the progress of the game is disabled is not released. In other words, even when it is not possible to properly determine whether or not to win the winning combination in the internal lottery, the game may be played based on the setting value selected and set based on the setting change operation. Since it is secured, the fairness of the game can be achieved.

  Further, the data stored in the RAM 112 is abnormal in most cases when the control cannot be continued due to a malfunction in the control such as a power failure or the control unit 110 running away. Since it is determined whether or not the data is normal only when the control unit 110 is activated after recovering from these states, the determination whether or not the data stored in the RAM 112 is normal is abnormal. Can only be done in situations where there is a high probability that That is, in a situation where there is a low possibility that an abnormality has occurred in the data stored in the RAM 112, it is not necessary to perform the determination, and the load on the control unit 110 can be reduced.

  In particular, in the power interruption interrupt process executed by the input of the voltage drop signal generated when the power is cut off, the RAM parity is calculated based on the data stored in the RAM 112 and stored in the parity storage area 112-7. At the next startup, the RAM parity obtained by the calculation is compared with the RAM parity stored in the parity storage area 112-7 to determine whether the data in the RAM 112 is normal. doing. In this way, it is possible to determine whether or not the data in the RAM 112 is normal only by comparing the RAM parity at the time of input of the voltage drop signal generated when the power is shut off and at the time of start-up. Can do.

  In addition, when an abnormality occurs in the data of the RAM 112 and the progress of the game is disabled, a setting change mode in which a setting value changing operation that becomes a condition for releasing the disabled state of the game is enabled Along with the transition to (setting change process), the data stored in the RAM 112 is initialized. For this reason, the initialization of data associated with the occurrence of an abnormality in the data in the RAM 112 and the initialization of data associated with selection / setting of the set value can be performed at one time, so that useless processing can be omitted. .

  Further, when the control unit 110 is activated, it is determined whether or not the setting key switch 92 is ON before determining whether or not the data in the RAM 112 is normal. At that time, the setting key switch 92 is If it is determined that the data is in the ON state, the process proceeds to the setting change mode without determining whether the data in the RAM 112 is normal. In this way, a new set value is selected and set without determining whether or not the data in the RAM 112 is normal, so that useless processing can be omitted.

  The present invention is not limited to the above-described embodiment, and various modifications and applications are possible. Hereinafter, modifications of the above-described embodiment that can be applied to the present invention will be described.

  In the above-described embodiment, the gaming state of RT ends when the number of games digested from the start from the RT reaches 5 games. In this case, however, when the regular bonus, the big bonus (1), or the big bonus (2) is elected and controlled by the RT, depending on the timing at which the RT symbol is derived, the continuous production may end. In some cases, the gaming state of RT ends. Therefore, even if the gaming state of RT is controlled by RT triggered by the winning of regular bonus, big bonus (1) or big bonus (2), when 5 games are consumed from the derivation of RT symbol It may be terminated. When the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is set, the gaming state may always be controlled to RT.

  If the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is set and the gaming state is controlled to RT, the regular bonus, big bonus (1) or Winning the big bonus (2) becomes very difficult. Therefore, after the predetermined number of games have been consumed after the gaming state is controlled to RT, winning flags other than the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag are set repeatedly. However, the regular bonus, the big bonus (1), or the big bonus (2) can be preferentially won.

  For example, if the stop button 12L, 12C, 12R is operated at the timing when “BAR” is aligned on the active line in a state where the regular bonus winning flag and the bell winning flag are set, the symbol “BELL” is also displayed. Can be aligned on the active line. In this case, when the number of digested games after the gaming state is controlled to RT exceeds the predetermined number of games, “BAR” is aligned on the active line at a higher rate than “Bell” (100% may be sufficient). Also good. Even in other cases, the stop buttons 12L, 12C, and 12R are operated at the timing when “BAR” is aligned on the active line with the regular bonus winning flag and the bell winning flag set in the RT gaming state. If so, “BAR” instead of “Bell” may be aligned on the active line at a predetermined ratio (however, less than 50%).

  In the above embodiment, the game is controlled to the RT gaming state triggered by winning RT in the normal gaming state and winning the regular bonus, big bonus (1) or big bonus (2). It was. In the latter case, the game state is RT, and replays and other small roles are always won in most games, but continuous production is not performed. Therefore, if the regular bonus, the big bonus (1) or the big bonus (2) is won, the gaming state is not controlled to RT, and the gaming state is changed to RT when the RT symbol is derived as the reach eye. It may be controlled.

  Here, as the processing on the game control board 101 side, even if the processing of steps S516 and S517 in FIG. 14 is deleted and the regular bonus, the big bonus (1) or the big bonus (2) is won, the gaming state is RT It is only necessary to prevent it from being controlled. Further, in step S813 in FIG. 17, the variable display device is used regardless of whether it is an RT prize due to a combination small combination missing or a regular bonus, a big bonus (1) or a big bonus (2) at the time of winning. It is possible to determine whether or not the RT symbol has been derived on the active line as the display result of 2, and when the RT symbol is derived, 6 may be set as the initial value of the RT counter to control the gaming state to RT. . The processing on the side of the effect control board 102 may be the same as that in the above embodiment.

  Even in this case, since the continuous production is performed in response to the derivation of the RT symbol, it becomes easy for the player to visually understand the opportunity to start the continuous production. Also, whether the RT symbol was derived as a result of missing a combination small part or as a reach when the regular bonus, big bonus (1) or big bonus (2) is won Regardless, it is an opportunity to control the gaming state to RT. Other than this, the gaming state is not controlled by RT.

  For this reason, the player does not know that the gaming state is controlled to RT without the RT symbol being derived, and the regular bonus, big bonus (1) or Players will no longer know if they have won the big bonus (2). Thereby, the continuous production (and additional production) can surely raise the player's expectation, and the interest of the game can be improved.

  In the above embodiment, the continuous production is started when the RT symbol is derived. However, if the regular bonus, big bonus (1) or big bonus (2) is won and the gaming state is controlled to RT, the gaming state will be RT and it will always win replays and other small roles in most games. However, continuous production is not performed. Therefore, instead of triggering the derivation of the RT symbol, the continuous production may be started when the gaming state is controlled by the RT.

  Here, the processing on the game control board 101 side may be the same as the above embodiment. As processing on the side of the effect control board 102, in step S1108, it is only necessary to determine whether the gaming state has changed to RT, instead of determining whether the RT symbol has been derived. This is the game state for two times stored in the RAM 122. If the game state of the current game is RT and the game state of the previous game is normal, it is determined that the game state has changed to RT. be able to.

  Here, the trigger for executing the continuous performance is not the derivation of the RT symbol, but the gaming state is controlled by the RT. In this way, the continuous production is executed by controlling the gaming state in RT, so that the regular bonus, the big bonus (1) or the big bonus (2) can be won or lost in the continuous production. It is possible to further reduce the number of cases where the player knows whether the regular bonus, the big bonus (1) or the big bonus (2) has been won before the end of the continuous performance by deriving the eyes. it can. For this reason, while a continuous production continues, it is possible to give the player a sense of expectation in a period longer than one game, and to improve the interest of the game.

  In the above embodiment, the RT is controlled by winning the RT by winning a combination bonus or by winning the regular bonus, the big bonus (1), or the big bonus (2). However, the condition for controlling to RT is not limited to this, and the gaming state is controlled to RT by winning a specific small role (for example, watermelon), and the gaming state is controlled to RT. It is good also as what starts a continuous production. In this case, it is only necessary to include a case where a specific small role is a lottery target at the same time as the regular bonus, the big bonus (1), or the big bonus (2).

  FIG. 24 is a diagram showing a winning combination table according to gaming state applied in this modification. In this modification, the combination small combination is not a lottery target combination. In FIG. 24, regular bonus + watermelon, big bonus (1) + watermelon, or big bonus (2) + watermelon are regular bonus, big bonus (1) or big bonus (2) and watermelon. At the same time, it is a lottery target role.

  When the game state is a regular bonus (including when it is offered during a big bonus), regular bonus + watermelon, big bonus (1) + watermelon, big bonus (2) + watermelon, watermelon, bell, cherry Are sequentially read as target roles. However, even if regular bonus + watermelon, big bonus (1) + watermelon, big bonus (2) + watermelon are eligible for internal lottery, regular bonus, big bonus (1) or big The bonus (2) is not won, and the winning determination when these are read out as the internal lottery winning combination is only a watermelon winning.

  When in normal gaming or RT, regular bonus, regular bonus + watermelon, big bonus (1), big bonus (1) + watermelon, big bonus (2), big bonus (2) + watermelon, watermelon, bell, Cherry and replay are sequentially read out as the target for internal lottery. Although the replay in the normal gaming state and the replay in RT are separately determined as the target for internal lottery, the replay winning flag set when winning is the same.

  Also, in a normal gaming state or RT, a regular bonus winning flag, a big bonus (1) winning flag, or a big bonus (2) winning flag is set in the game before the previous time, and the game is carried over without winning based on the flag. As in the above embodiment, the regular bonus, the big bonus (1), and the big bonus (2) are not subject to the internal lottery. In the normal gaming state or RT, the regular bonus + watermelon, big bonus (1) + with the regular bonus win flag, big bonus (1) win flag or big bonus (2) win flag already set Even when the winning decision is made when the watermelon, big bonus (2) + watermelon is read out as the target of the internal lottery, the watermelon is only won.

  As processing on the game control board 101 side here, when it is determined in step S514 in FIG. 14 that an overflow has occurred, the gaming state is in a regular bonus (including the case where it is provided in the big bonus). Whether or not the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag has already been set.

  If the game state is not a regular bonus and the regular bonus winning flag, big bonus (1) winning flag and big bonus (2) winning flag are not set yet, both winning flags (for example, lottery) If the target combination is regular bonus + watermelon, a regular bonus winning flag and a watermelon winning flag) may be set in the RAM 122. Otherwise, only the watermelon winning flag may be set in the RAM 122, or none of the winning flags may be set.

  Further, the processing of steps S516 and S517 in FIG. 14 may be deleted so that the gaming state is not controlled by RT even if the regular bonus, the big bonus (1) or the big bonus (2) is won. Further, in step S813 in FIG. 17, it is determined whether or not a watermelon small role has been won, and when winning a watermelon small role, 6 is set as the initial value of the RT counter and the gaming state is controlled to RT. It is good also as what to do. Further, as processing on the side of the effect control board 102, it is only necessary to determine whether or not the gaming state has changed to RT instead of determining whether or not the RT symbol has been derived in step S1108.

  Note that, in the role-specific table corresponding to the gaming state-specific winning combination table of FIG. 24, for each difference in the number of bets, a lottery target role in which the determination value number is stored in common for each of the setting values 1 to 6; There may be a lottery target combination in which the number of determination values is individually stored according to each of the setting values 1 to 6. In the latter case, there may be a lottery target combination in which different determination values are stored for each set value and a lottery target combination in which the same number of determination values is stored regardless of the set value.

  In this case, since the continuous production is started in response to the winning of the watermelon small part, the opportunity for starting the continuous production is easy to understand visually for the player. In addition, when winning a watermelon small role, it is not just a start of continuous production, but it is highly probable that it will win a regular bonus, a big bonus (1) or a big bonus (2) by itself. It is shown that. This is because in the internal lottery, a regular bonus, a big bonus (1) or a big bonus (2) may be won simultaneously with the watermelon. As a result, in addition to receiving a payout by paying out 15 medals, the watermelon prize can give the player a sense of expectation for winning the regular bonus, the big bonus (1) or the big bonus (2). Can improve the interest of the game.

  In the modification described with reference to FIG. 24, the regular bonus, the big bonus (1) or the big bonus (2) and the watermelon are set as the lottery targets at the same time. Including this, the lottery for the special role such as the regular bonus, the big bonus (1) or the big bonus (2) and the lottery for the non-special role (small role, replay) are performed in the same flow. On the other hand, the lottery for special roles and the lottery for non-special roles may be performed separately. In this case, the internal lottery in the modification described with reference to FIG. 24 can be further modified as follows.

  FIG. 25 is a diagram schematically showing a winning determination table applied in this further modification. FIG. 26 is a flowchart showing in detail a lottery process applied in this further modification. Other configurations and processes are the same as those of the slot machine of the modification described with reference to FIG.

  As shown in FIG. 25, the winning determination table includes a small role winning determination table and a bonus winning determination table for each gaming state, which are stored in the ROM 113 in advance. Both the small role winning determination table and the bonus winning determination table are prepared according to the set values, and those corresponding to the set values are used in the lottery process, but the illustration is omitted here. doing.

  Here, as shown in FIG. 25A, in the normal game state, the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is not carried over from the previous game. Sometimes, an internal lottery is performed using both the small role table (1) corresponding to the normal gaming state and the bonus winning determination table. In FIG. 25 (a), the hatched range is a regular bonus, a big bonus (1) or a big bonus (2) and a watermelon if the random number for internal lottery is a value within this range. It is the range that will be won by overlapping.

  On the other hand, even in the normal game state or RT, when the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is carried over from the previous game, FIG. As shown in (b), the internal lottery is performed using only the small role table (1) corresponding to the normal gaming state. When the game state is a regular bonus (including the case where the bonus is provided during the big bonus), the regular bonus, the big bonus (1), and the big bonus (2) are not drawn in the first place, and therefore, as shown in FIG. 25 (c). As described above, only the small role table (2) corresponding to the regular bonus is used, and the internal lottery is performed.

  In the lottery process shown in FIG. 26, the process of steps S1401 to 1405 and the point of shifting to the RAM abnormality error process when it is determined in step S1402 that the set value is not in the range of 1 to 6 are described above. This is the same as the lottery process (steps S501 to S505 in FIG. 14). In addition, the process of transmitting an internal winning command after the setting status of the winning flag in the game is confirmed (step S1416) is the same as the process of step S519 in FIG.

  After obtaining a random number for internal lottery in step S1405, a small role winning determination table prepared according to the current gaming state (normal and RT, or regular bonus) and a set value is used for winning determination used for internal lottery. It sets as a table (step S1406). Next, the winning value of each combination registered in the set small role winning determination table is sequentially compared with the random value for internal lottery acquired in step S1405 (step S1407) and set. It is determined whether or not any combination registered in the small combination winning determination table is won (step S1408). When any winning combination is won, the winning flag of the winning combination is set in the RAM 112 (step S1409), and the process proceeds to step S1410. If no winning combination is won, the process proceeds to step S1410.

  In step S1410, it is determined whether the current gaming state is a regular bonus or a big bonus depending on whether a regular bonus flag or a big bonus flag is set in the RAM 112. If the current gaming state is a regular bonus or a big bonus, the process directly proceeds to step S1416.

  If the current gaming state is neither a regular bonus nor a big bonus, it is either a normal gaming state or an RT. In this case, the regular bonus winning flag, big bonus (1) winning flag or big bonus ( 2) It is determined whether or not the winning flag has already been set in the previous game and is carried over without winning (step S1411). If the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is already set, the process proceeds to step S1416.

  If none of the regular bonus winning flag, the big bonus (1) winning flag and the big bonus (2) winning flag is set, the bonus winning determination table corresponding to the set value is used as the winning determination table used for the internal lottery. Setting is performed (step S1412). Next, the winning value of each combination registered in the set bonus winning determination table is sequentially compared with the random value for internal lottery acquired in step S1405 (step S1413), and the set bonus is determined. It is determined whether or not any combination registered in the winning determination table is won (step S1414). When any winning combination is won, the winning flag of the winning combination is set in the RAM 112 (step S1415), and the process proceeds to step S1416. If no winning combination is won, the process proceeds to step S1416.

  In this way, a separate winning determination table is prepared for the special role and the non-special role, and the random value for internal lottery corresponds to the value that is won for the special role in the normal gaming state or RT and is not When the special role corresponds to the winning value, the special role and the non-special role are won simultaneously. In this case, even if the display result of the variable display device 2 is a prize for a small role or a replay based on a winning flag for a non-special role such as a small role or a replay, the special role is still won. there is a possibility. Thereby, a player's expectation with respect to the winning of the special role can be enhanced, and the interest of the game can be improved.

  Further, even if the special combination is not won as a result of the internal lottery, there is a possibility that the small combination or replay is won, so that the player's expectation can be maintained. Furthermore, if the winning flag for the special role is not carried over from the previous game in the normal gaming state or RT, an internal lottery is performed using both the small role winning determination table and the bonus winning determination table. If the winning combination flag is carried over from the previous game, an internal lottery may be performed using only the small winning combination determination table. As a result, the normal game state and the internal lottery in RT can be performed by a simple process.

  In this further modification, the random numbers for internal lottery used for the determination of winning of special roles and the random numbers for internal lottery used for determination of winning of non-special roles were the same, but using different random numbers. It is good. In addition, regardless of whether the regular bonus winning flag, big bonus (1) winning flag, or big bonus (2) winning flag is carried over, in the normal gaming state or RT, a small bonus winning determination table and bonus are provided. A lottery is performed using both the winning determination tables, and the regular bonus when the regular bonus winning flag, big bonus (1) winning flag, or big bonus (2) winning flag is carried over from the previous game. When winning the big bonus (1) or the big bonus (2), the winning may be invalidated.

  In the above embodiment, the number of determination values stored in the address registered in the role-specific table is added to the random number for internal lottery, and when an overflow occurs as a result of the addition, the winning combination is won. I was supposed to. On the other hand, the acquired number of determination values may be sequentially subtracted from the acquired internal lottery random value, and the result of the subtraction may be used as a new internal lottery random value. When the number of determination values is subtracted from the random number value for internal lottery, it can be determined whether or not an overflow has occurred in the subtraction result (here, the subtraction result becomes negative).

  In the above embodiment, when the combination small combination is missed by the operation timing of the stop button 12R in the state where the combination small combination winning flag is set, the RT symbol is always derived on the active line. . This is because “BAR”, “Red 7”, and “White 7” are always arranged at intervals of 5 frames or less for the right reel 3R. On the other hand, when the combination small combination is missed in the state where the combination small combination winning flag is set, the RT symbol may be missed depending on the operation timing of the stop button 12R. For example, if the combination of the RT symbols is “Bell-Bell-Red 7” and the combination of “Bell-Bell-White 7” is not an RT symbol, the right reel 3R is not necessarily “BAR” or “Red 7”. ”Is not necessarily arranged at intervals of 5 frames or less, and RT symbols may be missed.

  In the above embodiment, the bonus type lottery is performed when the number of bets is set in the next game in which the confirmation of the bonus winning is notified, and on the condition that this is won, the type of bonus that has been won Was also supposed to be informed. If the bonus type lottery here is not won, the type of the winning bonus will not be notified. However, the conditions for notifying the timing of notifying the type of winning bonus are not limited to this.

  For example, after notifying that the bonus has been confirmed, a bonus type lottery is performed on the condition that even if the predetermined number of games is exhausted, no regular bonus, big bonus (1), or big bonus (2) will be won. It may be a thing. A bonus-type lottery may be performed in each game after notifying that the bonus has been won and winning either the regular bonus, the big bonus (1), or the big bonus (2). If you are notified of the bonus winning, and if you do not win any of the regular bonus, big bonus (1), or big bonus (2) even if you have exhausted the predetermined number of games, you will be informed of the type of bonus that has been won It is good also as what to do.

  In the above-described embodiment, the continuous effect continues for a period of two games or three games, and the additional effect continues for a period of one game or two games. On the other hand, since the gaming state of RT continues for a period of five games, when the continuous production (and additional production) ends, the gaming state is still in RT and the regular bonus, big bonus (1) or It may be difficult to win the big bonus (2).

  Therefore, the notification of the confirmation of the bonus winning may be performed after the end of RT after the continuous effect (and additional effect) ends. This makes the player feel unsatisfied without having to give the player the stress of being unable to win even though the regular bonus, big bonus (1) or big bonus (2) wins are known. Disappears. Notification of the confirmation of the loss may be performed after the end of RT.

  In the above embodiment, only when a regular bonus, a big bonus (1), or a big bonus (2) is won when a continuous production is being performed, an additional production following the end of the continuous production. Was supposed to do. On the other hand, when a regular bonus, a big bonus (1) or a big bonus (2) is newly won when a continuous production is being performed, an additional production is always performed following the end of the continuous production. However, even if the regular bonus, the big bonus (1) or the big bonus (2) are not newly won by the end of the continuous performance, the additional performance will be performed following the end of the continuous performance at a predetermined rate. Also good.

  In this case, if the regular bonus, the big bonus (1) or the big bonus (2) is not newly won by the end of the additional effect, the confirmation of the loss as a result of the additional effect is notified. Further, the additional effect in this case may be considered in the same way as the continuous effect, and a further extended additional effect may be performed. When a regular bonus, a big bonus (1) or a big bonus (2) is newly won while a continuous performance is being performed, even if an additional additional performance is performed, it will be extended again at the end of the additional performance. The confirmation of the bonus winning may be notified without.

  In this way, even if the regular bonus, the big bonus (1), or the big bonus (2) is not won, the additional effect is started after the end of the continuous effect by causing the case where the additional effect is performed. Even in such a case, the player's interest in winning the regular bonus, the big bonus (1) or the big bonus (2) is not reduced. Thereby, the interest of a game can be improved.

  In the above embodiment, when the internal winning command is received during execution of the continuous performance (that is, when the value of the continuous counter is not 0), the regular bonus, the big bonus (1), or the big bonus (2) is newly added. If it is determined whether or not it has been won, and if it is determined that it has been won, an additional effect pattern is selected at this point, and an initial value is set in the additional counter. On the other hand, when the continuous production is finished (when the determination result of step S1306 is YES), the selected continuous production pattern is not a fixed notification pattern, and the regular bonus and big by this time. It may be determined whether the bonus (1) or the big bonus (2) is won. Based on the determination result, an additional effect pattern can be selected for the first time, and an initial value can be set in the additional counter.

  In the above-described embodiment, the additional effect pattern is selected corresponding to the continuous effect pattern being executed. However, if the total effects of the individual games are combined, the number of wins is greater than the number of losers or the result of the individual games during the additional effects is included as a result of the effects of the individual games. On the condition, the additional effect pattern may be selected independently of the continuous effect pattern being executed.

  In the above embodiment, the continuous effect and the additional effect are performed by displaying images on the liquid crystal display 4. However, the sound output from the speakers 7L, 7R, 7U, the reel lamp 3LP, and the game effect are performed. You may perform using other production | presentation means, such as lighting of LED75A-75M. The effect means for performing the start effect and the restart effect, the effect means for effecting in each game, and the effect means for informing the confirmation of the loss or bonus winning may be different.

  In the above embodiment, each game effect in the continuous effect or the additional effect is started when the internal winning command is transmitted, that is, when the start lever 11 is operated. However, even if the start lever 11 is operated, if the predetermined time has not elapsed since the start of the previous game, the start of rotation of the reels 3L, 3C, 3R is put on standby. The effects of each game in the continuous effect or the additional effect may be started not when the start lever 11 is operated but when the reels 3L, 3C, 3R start to rotate. In this case, the processing in steps S1202 to S1208 in FIG. 21 may be performed following the processing in step S1005.

  In the embodiment described above, 11h is subtracted from the upper area data (step S605) before the final logical sum operation (step S610) of the upper area data and the lower area data is performed. The bit rotation is performed (step S606), the exclusive OR operation is performed on the lower area data (step S607), and the upper area data is processed in advance. However, not all of these steps are necessarily required, and either one or two may be applied, or these steps may not be performed at all.

  Here, if it is assumed that the process of step S607 is not performed, the process of step S608 performs an exclusive OR operation on the upper area data and the lower area data for each bit to obtain the exclusive logic. The result of the sum operation may be stored as new lower area data. Moreover, the order which performs the process of step S605-S607 can be changed into arbitrary orders. If at least one of steps S605 to S607 is applied, the upper region data after performing all the steps applied in steps S605 to S607 without performing step S610. May be the final upper byte data in the random number for internal lottery.

  In addition, the value to be subtracted in step S605 is not limited to 11h, and any value other than 00h can be added or subtracted. In step S606, the rotation is not limited to 1 bit, but 7 bits. Rotate up or down by any number of bits up to. The lower area data subjected to the exclusive OR operation in step S607 may be data obtained by performing a predetermined operation on the data first input to the lower area from the random number generation circuit 115. As a calculation performed on the data in the upper area, a calculation by an arithmetic expression other than this can be applied. Further, the save area data that is exclusively ORed with respect to the upper area data in step S610 may be data that is first input to the lower area from the random number generation circuit 115, and steps S607 and S609. May be data obtained by performing different predetermined calculations.

  In the above-described embodiment, data obtained by performing an exclusive OR operation on the data in the upper area subjected to the processing in steps S605 to S607 and the data in the lower area is used as the final lower byte data in the random number for internal lottery. On the other hand, the data first input to the lower area from the random number generation circuit 115 may be used as the final lower byte data in the random number for internal lottery. The data in the save area after adding 78h in step S609 may be used as the final lower byte data in the random number for internal lottery (or 78h is added to the data stored in the lower area in step S608 to obtain the final It is also possible to use low-order byte data). Furthermore, as a calculation to be performed on the data in the lower area, a calculation based on another calculation formula may be applied, and the calculation result may be the final lower byte data in the random number for internal lottery.

  In the above embodiment, for example, in step S605, 11h is subtracted from the data stored in the upper area of the RAM 112, and the data of the subtraction result is stored in the upper area. In step S607, the exclusive OR operation is performed on the data stored in the upper region of the RAM 112 and the data stored in the lower region of the RAM 112, and the result of the exclusive OR operation is stored in the upper region. Was supposed to be stored in. However, the direct calculation using the area of the RAM 112 is possible only when the instruction set of the CPU 111 is the 2-address system or the 3-address system.

  On the other hand, if the instruction set of the CPU 111 is a one-address system, for example, when performing subtraction as in step S605, the data stored in the upper area of the RAM 112 is first loaded into the accumulator (general-purpose register) Then, 11h is subtracted from the accumulator data, and the subtraction result data is stored again in the accumulator. Here, when the data stored in the upper area of the RAM 112 is loaded into the accumulator, the accumulator effectively acts as the upper area. Here, the accumulator still operates on the data in the upper area. It is not necessary to store the data in the upper area of the RAM 112 yet.

  In step S606, the accumulator data in which the result of the subtraction in step S605 is stored is rotated down by 1 bit, and the resultant data is stored again in the accumulator. In step S607, an exclusive OR operation is performed on the data stored in the lower area of the RAM 112 for each bit of the accumulator data in which the result of the operation in step S606 is stored, and the resultant data is stored in the accumulator. To be. Since the accumulator is still functioning as the upper area of the RAM 112 at this point, the accumulator data may be stored in the lower area of the RAM 112 in step S608.

  Further, in step S609, the data in the save area of the RAM 112 is loaded into the accumulator. Here, the accumulator functions as the save area, and 11h is added to the accumulator data and stored in the accumulator. In step S610, the data of the accumulator is exclusive ORed with the data in the upper area of the RAM 112 for each bit, and the result is stored in the accumulator. After the result of the exclusive OR operation is stored, The accumulator will again act as the upper region.

  Thus, the accumulator in the CPU 111 having a one-address instruction set acts as any of the upper area, the lower area, and the save area depending on the data stored in the calculation process (although as described above) In the random number processing method, the accumulator does not act as a lower region). Similarly, the stack in the CPU 111 having the instruction set of the 0 address system also functions as any of the upper area, the lower area, and the save area depending on the data stored in the calculation process.

  Further, if the CPU 111 has a plurality of general-purpose registers, the RAM 112 may not be provided with an upper area and a lower area, but any two general-purpose registers may be applied as the upper area and the lower area. In particular, if the CPU 111 has a 2-byte general-purpose register in addition to the 1-byte general-purpose register, it may be used for the upper area and the lower area.

  In the above-described embodiment, the same upper region and lower region are stored in the region storing the 2n-bit numerical data fetched from the sampling circuit 116 and in the region storing the finally generated random numbers for internal lottery. However, it is also possible to use separate areas. For example, when a 2-byte random number area in which the finally generated random numbers for internal lottery are stored is provided separately from the upper area and the lower area, in step S608, the upper area data is transferred to the lower area of the random area. In step S609, the result of the exclusive OR operation may be stored in the upper byte of the random number area.

  In the above embodiment, the number of random numbers for internal lottery is 16 bits that is the same as the number of random numbers generated by the random number generation circuit 115 and takes a value of 0 to 65535. The range of values that can be taken by the random numbers for internal lottery may be made smaller by thinning out the bits. For example, after step S610, the most significant bits (the seventh bit and the fifteenth bit as random numbers for internal lottery) of the upper region and the lower region may be thinned out.

  In this case, the 8th to 14th bits of the random number that is the result of step S610 are shifted from the 7th bit to the 13th bit, and the 15th and 14th bits are set to 1 (as in the above-described modification). When winning determination is performed by subtraction, 0) can be inserted. The 2-bit numerical value indicated by the 14th bit and the 8th bit thinned out from the result of step S610 can be used for lottery of other processes (for example, effects for bonus notification). Thereby, the thinned bit value can also be used effectively.

  In the above-described embodiment, the random number generated by the random number generation circuit 115 is captured by the sampling circuit 116 with the order of the bits being changed between the upper 8 bits and the lower 8 bits, and the upper 8 bits of the random number captured by the sampling circuit 116. Bits are taken into the lower area of the RAM 112 and lower 8 bits are taken into the upper area of the RAM 112 to obtain a random number before processing. However, the present invention is not limited to this, and the processes shown in FIGS. 8A to 8D can be changed as shown in FIGS.

  In the example of FIG. 27, the random number generated by the random number generation circuit 115 is replaced with the upper 8 bits and the lower 8 bits in the same manner as in FIGS. (A) to (b). Next, the upper 8 bits of the random number taken by the sampling circuit 116 are taken into the upper area of the RAM 112 via the upper port, and the lower 8 bits are taken into the lower area of the RAM 112 via the lower port (b) to (d). Thereafter, the numerical data stored in the upper byte and the numerical data stored in the lower byte may be exchanged by software processing to obtain a random number before processing (e).

  Note that the connection order of the wiring between the random number generation circuit 115 and the sampling circuit 116 is reversed, and the arrangement order of the upper byte and the lower byte is not reversed for the random number that is first fetched into the RAM 112. The connection order of the wiring between the circuit 116 and the upper port: lower port is reversed, and the arrangement order of the upper byte and the lower byte of the random number that is first fetched into the RAM 112 is changed to the random number generated by the random number generation circuit 115. The order may be reversed. This point can also be applied to the example of FIG.

  In the example of FIG. 28, the connection of the wiring between the random number generation circuit 115 and the sampling circuit 116 is not reversed. First, the random numbers generated by the random number generation circuit 115 are sampled in the order in which the bits are arranged. (A) to (b). Next, the upper 8 bits of the random number taken by the sampling circuit 116 are taken into the upper area of the RAM 112 via the upper port, and the lower 8 bits are taken into the lower area of the RAM 112 via the lower port (b) to (d).

  Thereafter, the numerical data stored in the upper byte and the numerical data stored in the lower byte are switched by software processing (e). Furthermore, the random number before processing may be obtained by switching the bit arrangement order of the numerical data stored in the upper byte and the numerical data stored in the lower byte in reverse order by software processing (f). Note that the numerical data stored in the upper byte and the numerical data stored in the lower byte are first changed to reverse the bit order of the numerical data stored in the upper byte and the numerical data stored in the lower byte. May be replaced later.

  In the example of FIG. 29, the wiring between the random number generation circuit 115 and the sampling circuit 116 is reversed between the upper byte and the lower byte, and is connected so that the bit order does not change in each byte. . Here, the random number generated by the random number generation circuit 115 is taken into the sampling circuit by switching the upper byte and the lower byte (a) to (b). Next, the upper 8 bits of the random number taken by the sampling circuit 116 are taken into the upper area of the RAM 112 via the upper port, and the lower 8 bits are taken into the lower area of the RAM 112 via the lower port (b) to (d).

  Thereafter, the bit order of the numerical data stored in the upper byte and the numerical data stored in the lower byte may be reversed in a software process to obtain a random number before processing (e). Note that the arrangement order of the wiring between the random number generation circuit 115 and the sampling circuit 116 is not changed, and the upper byte of the sampling circuit 116 may be connected to the lower port of the CPU 111 and the lower byte may be connected to the upper port. .

  In the example of FIG. 30, the wiring between the random number generation circuit 115 and the sampling circuit 116 is completely connected in reverse order. Here, the sampling circuit 116 takes in the order of the random number bits generated by the random number generation circuit 115 in the reverse order (a) to (b). Then, the upper byte and lower byte of the random number fetched by the sampling circuit 116 may be fetched as they are into the upper area and lower area of the RAM 112 via the upper port and lower port as they are (b) to (d).

  In the above embodiment, the lower byte of the random number for the internal lottery is generated by reversing the order of the bits of the upper byte of the random number generated by the random number generation circuit 115, and the lower byte of the random byte generated by the random number generation circuit 115. The upper order byte of the random number for internal lottery was set in reverse order. However, the order in which the bits are arranged in each byte is not necessarily limited to the reverse order. For example, the most significant bit and the least significant bit in each byte may be interchanged. However, in particular, it is preferable that as many bits as possible be replaced in the upper byte of the random number generated by the random number generation circuit 115 with a small change in value according to the difference in timing.

  In the above embodiment, the determination value number storage area uses a 2-byte area to store the determination value number in each case. However, in a general slot machine, the number of judgment values for a combination such as a regular bonus, a big bonus (1), or a big bonus (2) may be set to exceed 255 in any gaming situation. Absent. Thus, for those that do not need to set the number of determination values exceeding 255, the number of determination values may be stored using only a 1-byte area.

  In the above embodiment, the number of determination values is stored in common for all of the setting values 1 to 6 or individually stored for each of the setting values 1 to 6. However, it is assumed that the number of determination values is not stored in common for all of the setting values 1 to 6 (the common flag for the setting value is not set). About 4-6, the number of judgment values can also be made common.

  In the above embodiment, in the normal gaming state or RT, the game can be started only by setting 3 as the number of bets. On the other hand, even in the normal gaming state or RT, it is possible to start the game by setting 1 as the number of bets, or to start the game by setting 2 as the number of bets. You may do it.

  When 1 or 2 is set as the bet number in the normal gaming state and RT, the winning probability of the small role in the internal lottery is lowered as compared with the case where 3 is set as the bet number, and when winning the small role The number of paid out medals can be increased. Further, in a slot machine that can set any one, two, or three bets as the number of bets in the normal gaming state and the small bonus game in the big bonus, the number of determination values is stored in common for all of the setting values 1 to 6. There may be a combination that is stored in common for all of the bets 1 to 3 as well as a combination that is stored. In this case, the storage area for the number of determination values can be reduced according to the number of bets, and the storage capacity can be further reduced.

  In the above embodiment, when the gaming state is the big bonus, if the regular bonus medium flag is not set in the RAM 112 when the start lever 11 is operated, this is set and controlled to the regular bonus. However, the condition for controlling the gaming state in the big bonus) to the regular bonus is not limited to this. For example, on the condition that a predetermined result (JACIN) is derived as the display result of the variable display device 2 in the big bonus. It is good also as what controls to a regular bonus. In this case, when the gaming state is controlled to the big bonus, JACIN is also selected as a lottery target in the internal lottery, and when JACIN is won, the JACIN winning flag may be set in the RAM 112. JACIN winning is subject to the setting of the JACIN winning flag.

  In the above embodiment, when the operation of the settlement button 16 is detected by the settlement switch 47, only medals for credits accumulated as data are paid out. At this time, the bet number is already set. If so, medals for the set number of bets may be paid out. However, when the bet number is automatically set by the replay winning of the previous game, the medals for the automatically set bet number are not paid out by the operation of the settlement button 16. Therefore, in order to be able to determine whether the bet number has been set by inserting medals or by operating the BET buttons 14 and 15, or whether the bet number has been automatically set by replay winning, the bet number is automatically set for the replay game flag After that, it can be erased by operating the start lever 11. The medal corresponding to the credit may be paid out by operating the first settlement button 16 and the medal corresponding to the bet number may be paid out by operating the second settlement button 16.

  In the above embodiment, the symbol of the winning combination is determined based on the symbol position and the setting status of the winning flag for each reel 3L, 3C, 3R when the operation of the stop button 12L, 12C, 12R is detected. The slot machine that stops the rotation of the reels 3L, 3C, and 3R is described as an example in a control method in which the pull-in control is performed so that the symbols are not aligned or the removal control is performed so that the symbols of the winning combination are not aligned.

  On the other hand, a reel in which the stop position of the symbol is registered in advance according to the setting position of the symbol position and the winning flag for each reel 3L, 3C, 3R when the operation of the stop button 12L, 12C, 12R is detected. With reference to a control table (selected in advance according to the setting status of the winning flag and the game state), the reels 3L, 3C, and 3R are stopped by a table system that stops the reel at the symbol stop position registered in the reel control table. The present invention can also be applied to a slot machine that stops rotation (see, for example, Japanese Patent No. 2627604). Here, in the reel control table, the stop position of the symbol is determined in advance, but is determined within the range of the maximum stop delay time of 190 milliseconds. That is, the symbols that are stopped by operating the stop buttons 12L, 12C, and 12R are selected within the range of the maximum stop delay time.

  The reel control table is selected in advance according to the setting state of the winning flag and the game state before the stop buttons 12L, 12C, and 12R are operated. Depending on which reel control table is selected, the reel control table is stopped. Even if the operation timings of the buttons 12L, 12C, and 12R are the same, the symbols to be stopped are different. Therefore, selecting the reel control table selects a symbol according to the setting state of the winning flag and the gaming state. Further, the reel control table registers the relationship between the symbol position displayed when the operation of the stop buttons 12L, 12C, and 12R is detected and the position where the symbol should be stopped. Since the symbol stop position registered corresponding to the symbol position when the operation of 12C, 12R is detected is selected, the symbol stop position is selected when the stop button 12L, 12C, 12R is operated. It can be said that it is a choice.

  In the above embodiment, the variable display device 2 includes the three reels 3L, 3C, and 3R in which a plurality of symbols are arranged in a predetermined order on the outer peripheral portion, and the symbols are driven by rotational driving of these reels 3L, 3C, and 3R. Was variably displayed. However, a device that virtually displays a symbol on a display device such as a liquid crystal display device may be used instead of the variable display device 2 described above.

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