Description

  The present invention relates to a slot machine, and more particularly, to derivation of a replay display result accompanied by a replay and a determination to allow a special display result accompanied by a transition of a game state.

  In general, a slot machine generally has a plurality of types of symbols such as “red 7”, “white 7”, “BAR”, “watermelon”, “bell”, “cherry”, “JAC” drawn on the outer periphery. A variable display device having three (usually three) reels is provided, and each reel starts to rotate when the player operates the start lever, and the player is provided corresponding to each reel. The rotation is stopped by operating the stop button. 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. Among these combinations, the bonus combination is a combination with a high expectation for the player because the player can make a profit over several games thereafter. A small role generally has more medals to be paid out than the number of bets, and can be said to be a role that brings profits to the player. On the other hand, it can be said that the replay role is a role that prolongs the progress of the game because there is no loss to the player.

  Which display mode is derived for each combination is determined according to the gaming state, and in order for any combination to win, before the display result is derived It is necessary to win the internal lottery performed in advance and set the corresponding winning flag. Here, in the internal lottery in the conventional slot machine, only one combination is won in one game (see, for example, Patent Document 1).

Japanese Patent No. 3474804

  Here, if one game is won in one game like a conventional slot machine, it means that a game won in a role other than the bonus is not won in the bonus. Bonus winnings in games prior to games won in non-bonus roles may be carried over, but winnings in non-bonus roles are irrelevant to the possibility of winning the bonus. Winning won't let the player expect a bonus win. Here, when the winning combination other than the winning bonus is replay, no profit including expectation is provided to the player.

  On the other hand, unlike the slot machine of Patent Document 1, when a bonus is won, the player can also win a replay at the same time. However, from the viewpoint of suppressing the shooting property, it is preferable that the probability of replay winning (in general, winning = winning) is a certain value or more. On the other hand, since a player can obtain a large profit by winning a prize, the winning probability cannot be increased so much in order to keep the payout rate for a certain long period within an appropriate range. Then, even if the player is expected to win a bonus when he wins a replay, the expectation will not be very high. I can't plan enough.

  The present invention allows the player to expect that the derivation of the replay display result accompanied by the replay is determined to permit the derivation of the special display result accompanied by the transition of the game state, thereby making the game more interesting. It is an object of the present invention to provide a slot machine that can improve the performance.

To achieve the above object, a slot machine according to the present invention includes:
A game can be started by setting a predetermined number of bets for one game using the game value, and a plurality of variable display portions (reels 3L, 3C, 3R) that can be distinguished from each other. One game is completed when a display result is derived to a variable display device (variable display device 2) that variably displays the type of identification information, and a winning can be generated according to the display result derived to the variable display device. In a slot machine,
A means for determining by lottery whether or not to allow a plurality of types of winning display results to be derived before the display result of the variable display device is derived. Special decision means for deciding whether or not derivation of the regular bonus, the big bonus (1), and the big bonus (2)) is allowed, and the replay that allows the next game to be played without using the gaming value Pre-determining means (step S403, FIG. 11) including re-game determining means for determining whether or not to allow a re-game display result (replay A, replay B) with grant of
Stop operation means (stop buttons 12L, 12C, 12R) for instructing to stop the variable display of the identification information on the variable display device by the player's operation;
Stop operation detection means (stop switches 42L, 42C, 42R) for detecting the operation of the stop operation means;
When the stop operation detecting means detects an operation of the stop operation means , the predetermining means derives the identification information located within a predetermined pull-in range when the operation is detected. When there is identification information corresponding to the permitted display result, control is performed to derive the identification information as one of the display results of the variable display device. Derivation control means (step S5);
Special game state control means (steps S702 and S704) for shifting the game state from the next game to a special game state different from the normal game state when the special display result is derived as the display result of the variable display device. ,
Special decision carry-over means for carrying over the decision to the next game when the advance decision means decides that the derivation of the special display result is allowed and the special display result allowed by the decision is not derived (step S810) )When,
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 setting value (setting value) from among the 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;
Holding means for holding data for controlling the progress of the game stored in the data storage means even when power supply to the slot machine is interrupted;
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 Setting value determining means for determining that the read set value data is appropriate and determining that the read set value data is not appropriate when the set value data is not within the range of the settable set value (steps S502, S503, S1002, S1003),
A second disabling means for disabling the progress of the game when the set value determining means determines that the read set value data is not appropriate (steps S503 (NO), S1003 (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. 8)
When the predetermining unit determines that the read set value data is appropriate by the set value determining unit, a winning display result in the game with a probability corresponding to the set value indicated by the read set value data Decide whether or not to allow
The re-game determining means is a combination of identification information derived to the plurality of variable display sections, regardless of whether or not the special decision carry-over means has carried forward the decision to permit the derivation of the special display result. The combination of the first regame display result (replay A) that is won by becoming the first combination (JAC-JAC-JAC) and the identification information derived to the plurality of variable display portions is partially variable The re-game display result including the second re-game display result (replay B) that is won by becoming the second combination (JAC-JAC-Bell) common to the first combination in the display unit is derived. Is determined with a probability greater than or equal to the probability of allowing the derivation of the special display result,
In the game in which the derivation control means is determined to permit the derivation of the replay display result, and the derivation control means is also determined to permit the derivation of the special display result, the operation procedure of the stop operation means is the special procedure. when none of the display result and該再game display result was derivable procedure, it performs control Ru the該再game display result is derived in preference to該特another display result,
The special determination means determines that the replay determination means permits the derivation of the second regame display result in a game for which the special determination carryover means does not permit the derivation of the special display result. When replayed, the re-playing permission special determining means for determining that the derivation of the special display result is permitted in the game (FIG. 4: regular bonus + replay B, big bonus (1) + replay B, big bonus ( 2) + replay B) included.

  In the slot machine, when it is determined that the derivation of the special display result is allowed, it may be determined that the derivation of the second regame display result is allowed. In addition, when it is determined that the derivation of the replay display result including the second regame display result is permitted and it is also determined that the derivation of the derivation of the special display result is permitted, the regame display result Will be derived at a higher rate. That is, when the second regame display result is derived, it is highly likely that it is determined that the derivation of the special display result is permitted. It is possible to increase the player's expectation that it is determined that the derivation is permitted.

  When it is determined that the derivation of the special display result is permitted, it may be determined that the derivation is permitted at the same time, but the second regame display result may be determined. There are a re-game display result and a second re-game display result. Therefore, even if the probability that the derivation is permitted as a whole re-game display result is determined to be higher than the probability that the special display result is allowed to be derived, the second re-game display result is derived. The probability of being determined to be allowed can be lower than the probability of determining to permit the derivation of the special display result, and the special display result is obtained when the second re-game display result is derived. It is possible to make the probability that it is determined that the derivation of is allowed to be higher than a certain value. For this reason, when the second re-game display result is derived, not only can it be expected that the derivation of the special display result is permitted, but the expectation can be high.

  The combination of identification information that wins the first regame display result (first combination) and the combination of identification information that wins the second regame display result (second combination) are partly variable. Common to the display unit. For this reason, when the variable display is stopped only in the part of the variable display parts, even if the re-game display result is derived, whether it becomes the first re-game display result or the second re-game display result The player does not know what will happen. Therefore, not only when it is determined that the derivation of the second regame display result that allows the derivation of the special display result is allowed, but also when the derivation of the first regame display result is allowed. Even when determined, the player can expect that the derivation of the special display result is still allowed when the variable display is stopped only in some of the variable display units. Can be improved.

  In addition, even if the prior determination means determines whether to permit the derivation of the second replay display result and whether to permit the derivation of the special display result by separate lottery, the same It may be determined by lottery. In the former case, if it is determined that the derivation of the special display result is allowed after the derivation of the second replay display result is determined, the determination that the derivation of the special display result is allowed Is performed by the special determination means when replaying is allowed. In addition, it is determined that the derivation of the special display result is permitted before deciding whether to permit the derivation of the second re-game display result, and thereafter, the second re-game determining means determines the second re-game display result. Even when it is determined that the derivation of the game display result is permitted, the determination that the derivation of the special display result is allowed is included in the range of the re-game permission special determination means. In the latter case, a part for determining whether or not to permit the derivation of the second replay display result in one lottery is included in the replay determination means, and the derivation of the special display result is permitted. The portion for determining whether or not the game is permitted is included in the special determination means when replaying is permitted.

  Further, the re-game determining means may include means for determining that the derivation of the second re-game display result is allowed even when it is not determined that the derivation of the special display result is allowed. The special determining means may include means for determining that the derivation of the special display result is permitted even when it is not determined that the derivation of the second regame display result is permitted.

  In addition, the game in which it is determined that the derivation of the replay display result is permitted and the derivation of the special display result is also permitted is the derivation of the special display result by the special determination carryover means. In the game where the decision to allow is carried over, when the re-game determining means determines that the derivation of the first re-game display result or the second re-game display result is permitted, the special decision carry-over In the game in which the derivation of the special display result is not carried over by the means, it is determined that the derivation of the second replay display result is permitted by the replay determination means, and the special determination means when the replay is permitted is determined by the special determination means. This includes both when it is determined to allow the derivation of the display result.

  The derivation control means derives the second regame display result regardless of the operation procedure of the stop operation means when it is determined that the derivation of the second regame display result is permitted. It may be a thing. In this case, in the game in which it is determined that the derivation of the replay display result is permitted and the derivation of the special display result is also permitted, the operation procedure of the stop operation means is the special display result. When any of the second regame display results is a procedure that can be derived, the second regame display results can be derived at a high rate at a rate of 100%. The same can be applied to the first regame display result.

By the way, when the data stored in the data storage means (RAM) in the slot machine has been broken in the past, the game cannot be progressed. The data in the data storage means is initialized 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, even in the slot machine, 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. In order to cancel the state where the game cannot be progressed here, it is necessary to initialize the data stored in the data storage means. In this case, the set value data is also initialized. However, in the slot machine, when the game cannot be advanced based on the fact that the data stored in the data storage means does not match the data before the power is turned off, a new set value is set based on the operation of the setting operation means. If not, 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, the setting value data stored in the data storage means is also read when the determination is made by the prior determination means, and it is determined whether or not the setting value indicated by the read setting value data 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.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  Further, on the front side of the slot machine 1, an effect by light is performed by light emission of game effect lamps 75 </ b> A to 75 </ b> M (see FIG. 2) as effect means so as to surround the variable display device 2 and the liquid crystal display 4. Game effect display sections 5A to 5M are provided. The game effect display units 5A to 5M perform effects by light in various patterns according to the progress of the game. Note that the light emission colors of the game effect display units 5A to 5M may be either single colors or multiple colors.

  FIG. 2 is a diagram showing a 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. 2, only the game control board 101, the hopper 80, and the switches 91 to 94 are connected, but the power supply board 100 also supplies power to other units. 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 process described later.

  The reset circuit 118 outputs a reset signal when the voltage rises to a level at which the control circuit 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, regular bonus medium signal, reel control signal, stop signal input from the game control board 101 via the reel relay board 103. The switch signal, medal IN signal, medal OUT signal, and winning status signal are output to the external device.

  Next, the configuration of the RAM 112 of the game control board 101 will be described. FIG. 3 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. 4A 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. In the slot machine 1, the special bonus is a regular bonus, a big bonus (1), a big bonus (2), JACIN, a small role is Cherry, a watermelon, a bell, and a replay role is Replay A and Replay B. It has been established.

  In addition, for Replay B and watermelon, a regular bonus, a big bonus (1), or a big bonus (2) and an internal lottery may be simultaneously used for lottery. However, the regular bonus, the big bonus (1), and the big bonus (2) are won at the same time as other roles due to the relationship between the symbol arrangement on the reels 3L, 3C, and 3R and the stop symbols registered in the reel control table. There is no.

  In the regular bonus game state, small roles such as cherry, watermelon and bell are determined as winning combinations. In the game state of the big bonus, the regular bonus and JACIN which are special roles and the cherry, watermelon and bell which are small roles are determined as winning roles. In the normal gaming state and RT, regular bonuses and big bonuses which are special roles, cherry, watermelon and bell which are small roles, and replay A and replay B which are replaying roles are defined as winning roles.

  The regular bonus is awarded when a combination of “BAR-BAR-BAR” is arranged on any of the active lines (five) in the normal gaming state, the RT or the small role game in the big bonus. When the regular bonus is won, the gaming state shifts from the normal gaming state to the regular bonus. The regular bonus ends when 12 games are consumed, or when 8 games are won (any kind of combination is possible), whichever comes first. While the game state is in the regular bonus, the regular bonus medium flag is set in the RAM 112 (including the case where it is provided during the big bonus described below).

  The big bonus comes in either the red 7-red 7-red 7 combination or the white 7-white 7-white 7 combination on the active line (5) in the normal gaming state or RT. Sometimes wins. When the big bonus is won, the gaming state shifts to the big bonus. In the big bonus, a game called a small role game can be played. While the gaming state is the big bonus, the big bonus medium flag is set in the RAM 112. The big bonus ends when the number of medals paid out to the player exceeds 465. Here, since the maximum payout number per game is 15, the upper limit of the payout medal number in the big bonus is 480. In the following description, when it is necessary to distinguish between the big bonus by “Red 7-Red 7-Red 7” and the big bonus by “White 7-White 7-White 7”, the big bonus (1), It shall be called a big bonus (2).

  JACIN is awarded when a combination of “watermelon-JAC-JAC” is placed on any of the active lines (5) in the small role game in the big bonus, but in a game state other than the small role game, Even if the combination is complete, JACIN won't win. When winning JACIN, the above-mentioned regular bonus is provided in the big bonus, and the regular bonus medium flag is also set in the RAM 112 in addition to the big bonus medium flag. When the regular bonus in the big bonus exceeds the above-mentioned 465, the regular bonus is terminated together with the big bonus.

  A watermelon is awarded when the combination of “watermelon-watermelon-watermelon” is aligned on any of the active lines (one or five) in any gaming state. A bell is awarded when the combination of “bell-bell-bell” is aligned on any of the active lines (one or five) in any gaming state. Cherry is awarded when the symbol “cherry” is derived on one of the active lines (one or five) for the left reel 3L in any gaming state.

  Replay A is awarded when the combination of “JAC-JAC-JAC” is aligned on either of the active lines (5) in normal gaming state or RT, but regular bonus and big bonus (small game and Regular Bonus) will not win Replay A even if this combination is available. Replay B wins when a combination of “JAC-JAC-Bell” is aligned on either of the active lines (5) in normal gaming state or RT, but regular bonus and big bonus (small game and In the regular bonus), even if this combination is complete, it will not be a Replay B prize.

  When winning a Replay A or Replay B (hereinafter referred to as a “Replay Winning”), no medals will be paid out, but the next game can be started without setting the number of bets again. The number of bets (3 because the regular bonus does not result in a replay win), that is, substantially the same as 3 medals corresponding to the 3 bets set in the previous game that generated the replay win. It becomes.

  The only roles that medals are to be paid out when winning are the small roles of cherry, watermelon and bell. The regular bonus, the big bonus (1), the big bonus (2), and the winning of JACIN are accompanied by the transition of the game state to the regular bonus or the big bonus, and are not eligible for paying out medals.

  Cherry, watermelon and bell can be awarded when the bet number is 1 (regular bonus) or 3 (game state other than regular bonus), but for the bell, when the bet number is 1, That is, when the gaming state is a regular bonus, 15 medals that are more than the other 8 are paid out. Regardless of the number of bets, the number of medals to be paid out when winning a cherry is 2 per active line, and if 3 wagers the cherry stops in the upper or lower tier, the total number is four. The number of medals to be paid out when winning a watermelon is fifteen.

  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 16383) 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.

  The reference of the combination according to the gaming state is performed according to the winning combination table by gaming state shown in FIG. In the winning combination table according to gaming state shown in FIG. 4A, regular bonus + replay B, big bonus (1) + replay B, or big bonus (2) + replay B, or regular bonus + watermelon, big bonus (1 ) + Watermelon or Big Bonus (2) + Watermelon means that Regular Bonus, Big Bonus (1), Big Bonus (2) and Replay B or Watermelon are eligible for lottery at the same time. It is.

  When the gaming state is a regular bonus (including the case where the bonus is provided during the big bonus), the cherry, watermelon, and bell are sequentially read as the internal lottery target roles, and the gaming state is in the small role game during the big bonus. Sometimes regular bonus + replay B, regular bonus + watermelon, regular bonus, big bonus (1) + replay B, big bonus (1) + watermelon, big bonus (2) + replay B, big bonus (2) + watermelon, Cherry, watermelon, bell, and JACIN are sequentially read out as the target combination of the internal lottery.

  In normal gaming state, regular bonus + replay B, regular bonus + watermelon, regular bonus, big bonus (1) + replay B, big bonus (1) + watermelon, big bonus (1), big bonus (2) + Replay B, Big Bonus (2) + Watermelon, Big Bonus (2), Cherry, Watermelon, Bell, Replay A, and Replay B are sequentially read out as the subject combination of the internal lottery. When the gaming state is RT, regular bonus + replay B, regular bonus + watermelon, big bonus (1) + replay B, big bonus (1) + watermelon, big bonus (2) + replay B, big bonus (2 ) + Watermelon, cherry, watermelon, bell, replay A, and replay B are defined as internal lotteries. Although the replay B in the normal gaming state and the replay B in the RT are separately determined as the target for internal lottery, the replay B winning flag set when winning is the same.

  In addition, when the regular bonus winning flag, big bonus (1) winning flag, or 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 (the game state is In this case, the regular bonus, the big bonus (1), and the big bonus (2) are not subject to the internal lottery.

  Further, when the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is already set (that is, when the gaming state is at RT), the regular bonus + replay Bor watermelon, Even if Big Bonus (1) + Replay Bor Watermelon, Big Bonus (2) + Replay Bor Watermelon is read out as a target for lottery, it is actually a regular bonus, big bonus (1) and big bonus (2). Will not win repeatedly, only Replay B or watermelon. The same applies to the big bonus (1) and the big bonus (2) when the gaming state is a small role game in the big bonus.

  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. 4B 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”).

  Regular Bonus + Replay B, Regular Bonus + Watermelon are subject to internal lottery in normal gaming state, small role game in RT or big bonus, and corresponds to 3 bets in normal gaming state, RT and small role game The storage address of the number of judgment values to be registered is registered. The value of the common flag of regular bonus + replay B and regular bonus + watermelon is 1. Regardless of the set value, a common storage address for the number of determination values is registered.

  Big Bonus (1) + Replay B, Big Bonus (1) + Watermelon, Big Bonus (2) + Replay B, and Big Bonus (2) + Watermelon are normal games, small games in RT or big bonus The storage address of the number of determination values corresponding to the number of bets 3 in the normal gaming state, RT or small role game is registered. For these roles, the value of the common flag is 1, and a storage address for the common number of determination values is registered regardless of the set value. In the small bonus game during the big bonus, the big bonus (1) and the big bonus (2) are not actually won, and here, Replay B or watermelon is won.

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

  Cherry is subject to internal lottery in any gaming state, and corresponds to the storage address of the number of judgment values corresponding to the bet number 1 with the regular bonus and the bet number 3 in the normal gaming state, RT or small role game. The storage address of the number of judgment values is registered. The value of the common flag for this combination is 0, and the storage address for the number of determination values is individually registered according to the set value corresponding to the number of bets.

  The watermelon is subject to internal lottery in any gaming state, and corresponds to the storage address of the judgment value number corresponding to the bet number 1 with the regular bonus and the bet number 3 in the normal gaming state, RT or small role game. The storage address of the number of judgment values is registered. The common flag of this combination is 1, and the storage address of the common determination value number is registered regardless of the set value corresponding to each bet number. Also for the bell, the storage address of the number of determination values is registered as in the case of the watermelon.

  JACIN is subject to internal lottery only in the small role game in the big bonus, and the storage address of the number of determination values corresponding to the bet number 3 in the small role game is registered. The value of the common flag for this combination is 1, and a common storage address for the number of determination values is registered regardless of the set value. Replay A is subject to internal lottery in the normal gaming state and RT, and the storage address of the number of determination values corresponding to the betting number 3 in the normal gaming state or RT is registered. The common flag of this combination is 1, and the storage address of the common determination value number is registered regardless of the set value corresponding to each bet number.

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

  FIG. 5 is a diagram illustrating a storage area for the number of determination values acquired based on 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, in the addresses ADD + 0, ADD + 2, ADD + 16, ADD + 18, ADD + 32, and ADD + 34, internal lottery targets are regular bonus + replay B, regular bonus + watermelon, big bonus (1) + replay B, big bonus (1) + watermelon, Big Bonus (2) + Replay B, Big Bonus (2) + Watermelon with 3 bets, that is, an address referenced regardless of the set value in the normal gaming state, RT or small role game Yes, 10 which is the value stored in each is acquired as the number of determination values.

  Addresses ADD + 4, ADD + 6, ADD + 8, ADD + 10, ADD + 12, and ADD + 14 are addresses that are referenced when the internal lottery is a regular bonus, the number of bets is 3, and the set value is 1-6. Regarding the regular bonus, the number of determination values is individually stored according to the set value, but since the same number of determination values 11 is stored, the winning probability of the regular bonus is the same at any set value. ing. Regardless of the set value, the regular bonus + replay B and regular bonus + watermelon judgment value counts are the same regardless of the set value. It will be the same.

  Addresses ADD + 20, ADD + 22, ADD + 24, ADD + 26, ADD + 28, and ADD + 30 are addresses that are referenced when the internal lottery target is the big bonus (1), the bet number 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. Big bonus (1) + replay B, big bonus (1) + watermelon judgment value number is common regardless of the set value, so even if you win at the same time as replay B or watermelon, The winning probability differs depending on the set value.

  The addresses ADD + 36, ADD + 38, ADD + 40, ADD + 42, ADD + 44, and ADD + 46 are addresses that are referred to when the internal lottery target role is the 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. Big Bonus (2) + Replay B, Big Bonus (2) + Watermelon judgment value number is common regardless of the set value, so even if you win at the same time as Replay B or Watermelon, The winning probability differs depending on the set value.

  Addresses ADD + 48, ADD + 50, ADD + 52, ADD + 54, ADD + 56, and ADD + 58 each have a bet number of 3, that is, in the normal gaming state, RT, or small role game, and the target value of the internal lottery is cherry and the set value is 1-6 An address that is sometimes referred to. Addresses ADD + 60, ADD + 62, ADD + 64, ADD + 66, ADD + 68, and ADD + 70 are addresses that are referenced when the bet number is 1, that is, when the target character of the internal lottery is a cherry and the set value is 1 to 6 in the regular bonus It is.

  The address ADD + 72 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, RT, or small role game, when the internal lottery target role is a watermelon. The address ADD + 74 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. Regular bonus + watermelon, big bonus (1) + watermelon, big bonus (2) + watermelon judgment value number is registered regardless of the set value, so even if you consider these, the watermelon winning probability is in the gaming state Regardless, it will be the same.

  The address ADD + 76 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, RT, or the small lottery game, when the internal lottery target role is a bell. The address ADD + 78 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 character of the internal lottery is a bell. The number of judgment values for the bell is registered according to the number of bets, but since different values are registered, there is a case where the game state is a regular bonus and a small value in the normal game state, RT or big bonus. The probability of winning the bell will differ depending on the role game.

  Addresses ADD + 80, ADD + 82, ADD + 84, and ADD + 86 have an internal lottery subject of JACIN with 3 bets, replay A with 3 bets, normal replay B with 3 bets, and RT with replay B In this case, the addresses are referred to regardless of the set value when the betting number is 3, and 4431, 2245, 1 and 12652 are obtained as the determination value numbers regardless of the set value.

  Replay A and Replay B enable winning the next game without consuming medals for setting the number of bets by winning, thereby suppressing consumption of medals. Here, in order to ensure that the number of medals consumed per unit time is within a certain number, the probability of internally winning Replay A or Replay B (including duplication) in a normal gaming state must be a certain probability or more. I must. This probability is considerably higher than the probability of winning the regular bonus, the big bonus (1), or the big bonus (2). However, when replay B is won (winning = winning), the probability of winning the regular bonus, big bonus (1) or big bonus (2) is the single replay B in the normal gaming state. Since the number of determination values is only one, (10 + 10 + 10) / (10 + 10 + 10 + 1) ≈1 / 1.03 is very high.

  In addition, the winning probability of Replay B when it overlaps with regular bonus, big bonus (1) or big bonus (2) is the same in both normal gaming state and RT, but the winning probability of single Replay B is usually It is higher at RT than in the gaming state. That is, when the gaming state is RT, that is, when the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is carried over from the previous game, the winning probability of Replay B is normal. It becomes higher than the gaming state. The winning probability of Replay A does not change between the normal gaming state and RT.

  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. The watermelon winning flag and the replay B winning flag set by winning at the same time as the regular bonus, the big bonus (1) or the big bonus (2) are also deleted as long as the game is concerned.

  Also, in the normal gaming state, a regular bonus, a big bonus (1) or a big bonus (2) is won (including duplicate winning with Replay B or watermelon), a regular bonus winning flag, a big bonus (1) winning flag or When the big bonus (2) winning flag is set, an RT flag is also set in the RAM 122. If the regular bonus, big bonus (1) or big bonus (2) is won in the game, the RT flag is cleared. Otherwise, the regular bonus, big bonus (1) or big bonus ( The gaming state is controlled to RT until winning 2).

  Next, acquisition of random numbers for internal lottery will be described in detail. 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 extracted from the random number generation circuit 115 or processed from 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.

  First, extraction of random numbers from the random number generation circuit 115 will be described. FIG. 6A 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. Further, when the level of the seventh bit data signal is inverted from the H level to the L level, that is, whenever the logic value of the seventh bit data signal changes from 1 to 0, a carry signal is output. 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 is configured by a latch circuit, and latches the 16-bit data signal output at that time from the random number generation circuit 115 based on a sampling command from the CPU 111 and outputs the latched data signal. The CPU 111 extracts numerical data corresponding to the data signal input from the sampling circuit 116 via the I / O port 114 as a random number 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.

  Next, processing of random numbers extracted from the random number generation circuit 115 by software will be described. FIG. 6B 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. The random number extracted from the random number generation circuit 115 is stored in a 16-bit general-purpose register 111GR included in the CPU 111.

  When the random number extracted from the random number generation circuit 115 is stored in the general-purpose register 111GR, the CPU 111 uses the other general-purpose register or the work area of the RAM 112 to lower byte of the general-purpose register 111GR (value extracted from the lower counter 115b). And the value of the upper byte (the value extracted from the upper counter 115c) are exchanged.

  Next, the CPU 111 performs an AND operation on the value of the random number obtained by exchanging the upper byte and the lower byte for the extracted random number with 8080h. Since the processing word of the CPU 111 is 1 byte, the logical product operation is actually performed sequentially on the upper byte and the lower byte. The 15th bit and the 7th bit are always 1 by this logical product operation. Further, the CPU 111 shifts the upper 1 byte (8th bit to 15th bit) to the lower bit by bit, and inserts 1 into the empty 15th bit.

  The CPU 111 acquires the value stored in the general-purpose register 111GR at this time as a random number for internal lottery, stores it in a predetermined area of the RAM 112, and determines the determination value (actual value) of each combination registered in the winning determination table. Are sequentially compared with the upper limit judgment value only). Since the 15th and 14th bits of the random number for internal lottery are always 1, the random number for internal lottery is a random number having a size of 14 bits (16384), which is substantially 0 to 16383. It takes a value.

  Note that interrupts to the CPU 111 are prohibited during the period from the extraction of random numbers from the random number generation circuit 115 to the end of processing. This is to prevent the contents of the general-purpose register 111GR from being rewritten in the interrupt processing routine when an interrupt occurs to the CPU 111.

  When the winning flag is set according to the result of the internal lottery, the rotation of the reels 3L, 3C, 3R is stopped according to the setting state of the winning flag (including those carried over from the previous game) A reel control table for selecting a stop symbol is selected. In the reel control table selected when the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag and the replay A winning flag or the replay B winning flag are set in duplicate, The latter is derived in preference to the former. Since all of the reels 3L, 3C and 3R are arranged with intervals of 5 frames or less, in this case, the player will always win Replay A or Replay B, and the regular bonus, The big bonus (1) or the big bonus (2) is never won.

  Reel control table selected when regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag and watermelon winning flag, bell winning flag or cherry winning flag are set redundantly Then, the former is derived in preference to the latter. However, since “Red 7”, “White 7”, and “BAR” are arranged at intervals of 6 frames or more in any of reels 3L, 3C, and 3R, regular bonus and big bonus (1) And the big bonus (2) is missing, and when these are missed, it becomes possible to win a watermelon, bell or cherry.

  The CPU 121 of the effect control board 102 performs an effect by original control based on various commands sent from the CPU 111 of the game control board 101. The effect controlled by the CPU 121 of the effect control board 102 is continued for the next two games after winning the replay B (however, the regular bonus, the big bonus (1) or the big bonus (2)) There is continuous production (until winning). If a new replay B prize is generated during the continuation of the continuous presentation, the continuous presentation will be continued for two games from the new replay B prize.

  In order to perform such a continuous effect, the CPU 121 of the effect control board 102 knows whether or not a replay B prize has occurred and whether or not a regular bonus, a big bonus (1) or a big bonus (2) has been won. There must be. For this reason, when the display result is derived to the variable display device 2, the CPU 111 of the game control board 101 generates a winning information command indicating whether or not a winning has occurred and the type of winning that has occurred, and the effect control board 102 To be sent to.

  When the received winning information command indicates the replay B winning, the CPU 121 of the effect control board 102 starts the continuous effect and sets 2 as the initial value of the continuous effect counter. Even if the value of the continuous effect counter is not 0, 2 is set as a new initial value. If the received winning information command indicates a winning of regular bonus, big bonus (1) or big bonus (2), the value of the continuous effect counter is cleared to 0 and the continuous effect is ended. When the value of the continuous effect counter is not 0, if any of the replay B, the regular bonus, the big bonus (1) and the big bonus (2) is not indicated, the continuous effect is continuously executed and the continuous effect is performed. Subtract 1 from the counter value.

  In addition to the winning information command, the command transmitted from the game control board 101 to the effect control board 102 includes a BET command transmitted when setting the number of bets, and a winning flag transmitted when operating the start lever 11. Commands such as a winning status notification command that indicates a setting status, a reel stop command that is transmitted when the reels 3L, 3C, and 3R are stopped, and a status command that indicates a gaming status that is applied at the end of each game and that is applied to the next game There is.

  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 more.

  FIG. 7 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 process proceeds to the RAM abnormality error process 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. 8 (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. 8 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. 7, the game can be progressed and the game control process is started.

  FIG. 9 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 is played. 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. 10 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). Here, when the gaming state is a regular bonus (including the case where the bonus is 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 operated effectively. It becomes. 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 number of bets as in the previous game (3 in this embodiment) is automatically set by the replay flag (the replay flag is erased at this stage) and remains as it is. The start lever 11 becomes effective.

  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 this lottery process, a winning flag is set in the RAM 112 based on each lottery result, and a reel control table is selected. In addition, a winning status notification command indicating the setting status of the winning flag 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. 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.

  Thereafter, reel fluctuation stop processing is performed (step S405). In the reel fluctuation stop process, after a predetermined condition is established from the start of reel rotation (the reference position is detected by the reel sensors 3SL, 3SC, 3SR after the rotation speed reaches a certain speed), the stop buttons 12L, 12C , 12R are made effective, and each is operated by a player to stop driving the reel motors 3ML, 3MC, 3MR with reference to a reel control table preselected according to the setting status of the winning flag, The rotation of 3C and 3R is stopped.

  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 any of the winning combinations has been won, various processes corresponding to winnings generated on the game control board 101 (regular bonus or big bonus generation processing, medal at the time of small winning combination, And a replay flag at the time of replay winning are set), and a winning information command indicating whether or not a winning has occurred and the type of winning that has occurred is transmitted 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. Various processes not related to winning (including processes related to the end of the regular bonus or big bonus) are also performed, and a state command indicating the gaming state to be applied in the next game is transmitted to the effect control board 102. The Then, the process for one game ends, and the process for the next one game starts. Details of the payout process will be described later.

  Next, the lottery process in step S403 will be described in detail. FIG. 11 is a flowchart showing details of the lottery process executed by the CPU 111 in step S403. In the lottery process, a random number acquisition process 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 (step S501). Details of the random number acquisition process will be described later.

  Next, the set value stored in the set value work 112-4 of the RAM 112 is read (step S502), 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 S503). 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. 9 is performed.

  If the read set value is in the range of 1 to 6, the lottery target combination registered in the winning combination table according to gaming state in FIG. 4A is read in order corresponding to the current gaming state ( Step S504). Next, 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. 4B is acquired corresponding to the number of BETs read out for the lottery target combination (step) S505). As a result, it is determined whether the common flag is set (step S506).

  If the common flag is set, the number of determination values stored in the address registered in the role-specific table of FIG. 4B corresponding to the number of BETs for the lottery target role is acquired (step S507). ). Then, the process proceeds to step S509. 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 that are present is acquired (step S508). Then, the process proceeds to step S509.

  In step S509, the number of determination values acquired in step S507 or S508 is added to the internal lottery random number value stored in the determination area of the RAM 112, and the addition result 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 S510).

  If no overflow has occurred, it is determined whether there is a combination that has not yet been processed among the lottery targets in the gaming state (step S511). If there is something that has not yet been processed, the process returns to the processing of step S504, 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 S530.

  If an overflow has occurred in step S510, the lottery role is a big bonus (1) + replay B, big bonus (1) + watermelon, big bonus (2) + replay B, big bonus (2) + watermelon It is determined whether or not any of the above (step S512). In the case of one of big bonus (1) + replay B, big bonus (1) + watermelon, big bonus (2) + replay B, big bonus (2) + watermelon, an RT flag is set in RAM 112. Whether or not the current gaming state is RT is determined based on whether or not it is present (step S513).

  If the current gaming state is not RT, 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 (step S514). ). If the current gaming state is neither a regular bonus nor a big bonus, a replay B winning flag or a watermelon winning flag is set in the RAM 112 together with a big bonus (1) winning flag or a big bonus (2) winning flag (step S515). ). Further, except when the RT flag is set in the RAM 112 and a big bonus (1) or big bonus (2) is won in the game (when the replay B winning flag is set, these are not won). The gaming state applied in the next game is set to RT (step S516). Then, the process proceeds to step S530.

  If the current gaming state is RT in step S513, or if the current gaming state is a regular bonus or a big bonus in step S514, a replay B winning flag or a watermelon winning flag is set in the RAM 112 (step S517). Then, the process proceeds to step S530.

  In step S512, if the winning combination is neither big bonus (1) + replay B, big bonus (1) + watermelon, big bonus (2) + replay B, big bonus (2) + watermelon, It is determined whether or not the winning combination is one of regular bonus + replay B and regular bonus + watermelon (step S518). In the case of either regular bonus + replay B or regular bonus + watermelon, it is determined whether the current gaming state is RT based on whether the RT flag is set in the RAM 112 (step S519).

  If the current gaming state is not RT, it is determined whether or not the current gaming state is a regular bonus (including a case where the bonus is provided during a big bonus) depending on whether or not the regular bonus flag is set in the RAM 112. (Step S520). If the current gaming state is neither a regular bonus nor a big bonus, a replay B winning flag or a watermelon winning flag is set in the RAM 112 together with the regular winning flag (step S521).

  Further, it is determined whether or not the current gaming state is a big bonus (except when it is a regular bonus) depending on whether or not the big bonus flag is set in the RAM 112 (step S522). If the current gaming state is not a big bonus, an RT flag is set in the RAM 112 (step S523). Then, the process proceeds to step S530. If the current gaming state is a big bonus, the process proceeds directly to step S530.

  If the current gaming state is RT in step S519 or if the current gaming state is a regular bonus in step S520, a replay B winning flag or a watermelon winning flag is set in the RAM 112 (step S524). Then, the process proceeds to step S530.

  In step S518, if the winning combination is neither regular bonus + replay B nor regular bonus + watermelon, the winning flag for the winning combination (here, only one of them) is set in the RAM 112. (Step S525). It is determined whether or not the current gaming state is RT depending on whether or not the RT flag is set in the RAM 112 (step S526).

  If the current gaming state is not RT, 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 (step S527). ). If the current gaming state is not a big bonus or a regular bonus, it is a normal gaming state.

  In this case, it is determined whether or not the winning combination is a regular bonus, a big bonus (1), or a big bonus (2) (step S528). If the winning combination is a regular bonus, a big bonus (1) or a big bonus (2), an RT flag is set in the RAM 112, and the regular bonus, big bonus (1) or big bonus ( The gaming state applied in the next game is set to RT except when winning in 2) (step S529). Then, the process proceeds to step S530.

  When the current gaming state is RT in step S526, when the current gaming state is a regular bonus or a big bonus in step S527, or in step S528 the lottery target is a regular bonus, big bonus (1) and big bonus. If none of (2), the process proceeds to step S530.

  In step S530, a reel control table corresponding to the setting status of the winning flag in the RAM 112 is selected. Then, the lottery process is terminated, and the process returns to the flowchart of FIG.

  Next, the random number acquisition process in step S501 will be described in detail. FIG. 12 is a flowchart showing in detail the random number acquisition process executed by the CPU 111 in step S501. In the random number acquisition process, first, an interrupt to the CPU 111 is prohibited (step S601). Next, a sampling command is output to the sampling circuit 116, the random number generated by the random number generation circuit 115 is latched, and the value of the latched random number is input from the I / O port 114 and extracted. The random number value extracted from the random number generation circuit 115 is stored in the general-purpose register 111GR (step S602).

  Next, the lower byte value and upper byte value of the random number stored in the general-purpose register 111GR are exchanged with each other (step S603). Next, the value of the random number stored in the general-purpose register 111GR is ANDed with 8080h (step S604). Further, the upper byte (15th to 8th bits) is shifted downward by 1 bit, and 1 is inserted into the empty 15th bit. At this time, the value stored in the general-purpose register 111GR is acquired as a random number for internal lottery and stored in a predetermined area of the RAM 112 (step S605). Then, after permitting the interrupt prohibited in step S601 (step S606), the random number acquisition process is terminated, and the process returns to the flowchart of FIG.

  Next, the winning determination process in step S406 will be described in detail. FIG. 13 is a flowchart showing in detail the winning determination process executed by the CPU 111 in step S406. First, it is determined whether a regular bonus display mode (BAR-BAR-BAR) or a JACIN display mode (watermelon-JAC-JAC) is derived on any active line (step S701).

  If the display mode of the regular bonus or the display mode of JACIN is derived, the gaming state becomes the regular bonus from the next game. Therefore, the number of games in the regular bonus in the RAM 112 and the counter value for counting winnings are initialized, and a regular bonus flag is set in the RAM 112. If the RT flag is set in the RAM 112, it is deleted. Further, when the regular bonus winning flag is set in the RAM 112, it is deleted (step S702). In any case, the JACIN winning flag is deleted in step S810, which will be described later, so it is not necessary to delete the JACIN winning flag here even if JACIN wins. Then, the process proceeds to step S713.

  If neither the regular bonus display mode nor the JACIN display mode is derived, the big bonus (1) display mode (red 7-red 7-red 7) or the big bonus (2) is displayed on any active line. It is determined whether an aspect (white 7-white 7-white 7) has been derived (step S703).

  If the display mode of the big bonus (1) or the big bonus (2) is derived, the gaming state becomes the big bonus from the next game. Therefore, a counter value for counting the number of payout medals in the big bonus in the RAM 112 is initialized, and a big bonus medium flag is set in the RAM 112. Also, the RT flag set in the RAM 112 is deleted. Further, the big bonus (1) winning flag or the big bonus (2) winning flag set in the RAM 112 is erased (step S704). Then, the process proceeds to step S713.

  When neither the display mode of the big bonus (1) nor the display mode of the big bonus (2) is derived, it is determined whether or not the display mode of cherry (cherry-ANY-ANY) is derived on any active line. Determination is made (step S705). If the cherry display mode is derived, 2 or 4 is set as the planned medal payout number according to the number of active lines from which the cherry display mode is derived (step S706). Then, the process proceeds to step S713.

  When the display mode of cherry is not derived, it is determined whether or not the display mode of watermelon (watermelon-watermelon-watermelon) is derived on any effective line (step S707). If the display mode of the watermelon is derived, 15 is set as the planned medal payout number (step S708). Then, the process proceeds to step S713.

  If the display mode of the watermelon has not been derived, it is determined whether or not the display mode of the bell (bell-bell-bell) has been derived on any effective line (step S709). If the bell display mode is derived, 15 (in regular bonus) or 8 (normal game state, RT or small role game) is set as the expected payout number of medals (step S710). Then, the process proceeds to step S713.

  If the display mode of the bell is not derived, it is determined whether the display mode of Replay A (JAC-JAC-JAC) or the display mode of Replay B (JAC-JAC-Bell) is derived on any active line. (Step S711). If the display mode of replay A or replay B is derived, a replay flag is set in the RAM 112 (step S712). This replay flag is deleted when the bet number is automatically set in the next game. Then, the process proceeds to step S713. If the display mode of replay A or replay B is not derived, the process proceeds to step S713 as it is.

  In step S713, a winning information command is generated that indicates which of the winning combinations has been won according to the display mode derived to the variable display device 2, or which type of winning combination has been won. 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. 14 is a flowchart showing in detail the payout process executed by the CPU 111 in step S407. In the payout process, until the planned payout number set in the RAM 112 becomes 0, the hopper 80 is controlled while subtracting the payout number one by one and the medals are discharged one by one, so that it corresponds to the winning combination Pay the number of medals to the player. However, if the number of credits has not reached 50, the number of credits is incremented by 1 instead of discharging medals one by one (step S801).

  Next, it is determined whether or not the current gaming state is a big bonus depending on whether or not the big bonus flag is set in the RAM 112 (step S802). If the current gaming state is not a big bonus, the process proceeds to step S806. If the current gaming state is a big bonus, the number of payout medals in the big bonus is counted using the counter of the RAM 112 (step S803). The number of payout medals counted here exceeds 465, and it is determined whether or not the big end condition is satisfied (step S804).

  If the number of payout medals does not exceed 465, the process proceeds to step S806. If the number of payout medals exceeds 465 and the big bonus ending condition is satisfied, the big bonus medium flag in the RAM 112 is deleted. If the regular bonus flag is set, it is also deleted (step S805). Then, the process proceeds to step S810.

  In step S806, it is determined whether or not the current gaming state is a regular bonus (including those provided during the big bonus) depending on whether or not the regular bonus flag is set in the RAM 112. If the current gaming state is not a regular bonus, the process proceeds to step S810. If the current gaming state is a regular bonus, the number of games and winnings in the regular bonus are counted using the counter of the RAM 112 (step S807).

  As a result of the count, it is determined whether the number of games has reached 12 or the number of winnings has reached 8, which is a regular bonus termination condition (step S808). If the number of games is less than 12 and the number of winnings is less than 8, the process proceeds to step S810 as it is. If the number of games has reached 12 or the number of winnings has reached 8, the regular bonus flag in the RAM 112 is erased (step S809). Then, the process proceeds to step S810.

  In step S810, if the small role (watermelon, bell, cherry) winning flag, replay A winning flag, replay B winning flag, and JACIN winning flag are set in the RAM 112, these are deleted. The regular bonus winning flag, the big bonus (1) winning flag, and the big bonus (2) winning flag are not deleted from the RAM 112 unless they have won the corresponding role in the game, and are carried over to the next game. Here, in this game, when the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag and the replay B winning flag or the watermelon winning flag are set at the same time, only the latter is set. Erase. Then, the payout process is terminated, and the process returns to the flowchart of FIG.

  In the repetition of the game as described above, the CPU 111 of the game control board 101 shifts the game state between the normal game state, RT, regular bonus, and big 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 based on the command received from the game control board 101. In the following, processing executed by the CPU 121 of the effect control board 102 to perform various effects (particularly, bonus effect after winning the replay B) will be described.

  FIG. 15 is a flowchart showing 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 S901). When any command is received from the game control board 101, the type of the received command is determined (step S902).

  If the received command type is the winning information command transmitted in step S713, it is determined whether or not the winning information command indicates a replay B winning (step S903). If the replay B winning is indicated, a continuous effect is started on the liquid crystal display 4 (step S904). After the continuous production starts, 2 is set as an initial value in the continuous production counter of the RAM 122 (step S905). Here, the initial value of 2 is set regardless of the value of the continuous performance counter. Then, the process returns to step S901.

  If the received prize information command does not indicate a replay B prize, it is determined whether the received prize information command indicates a regular bonus, a big bonus (1), or a big bonus (2) (step). S906). If the winning of the regular bonus, the big bonus (1), or the big bonus (2) is indicated, it is determined whether or not the value of the continuous effect counter in the RAM 122 is 0 (step S907). If the value of the continuous effect counter is 0, the process directly returns to step S901.

  If the value of the continuous effect counter is not 0, the continuous effect is still being executed. In this case, first, the continuous effect performed in the liquid crystal display 4 is ended (step S908). Further, the value of the continuous effect counter in the RAM 122 is cleared to 0 (step S909). Then, the process returns to step S901.

  If the received winning information command does not indicate any of the regular bonus, the big bonus (1), and the big bonus (2), it is determined whether or not the value of the continuous effect counter in the RAM 122 is 0 (step). S910). If the value of the continuous effect counter is 0, the continuous effect performed in the liquid crystal display 4 is ended here (step S911). Then, the process returns to step S901.

  If the value of the continuous effect counter is not 0, the liquid crystal display 4 continues the continuous effect. Here, the continuous effect may be changed in accordance with the value of the continuous effect counter (step S912). Further, 1 is subtracted from the value of the continuous effect counter in the RAM 122 (step S913). Here, when the value of the continuous effect counter becomes 0, the continuous effect is ended even if the regular bonus, the big bonus (1) or the big bonus (2) is not won unless the Replay B winning is generated in the next game. Become. Then, the process returns to step S901.

  Further, when the received command type is another command (including a BET command, a winning status notification command, a reel stop command, a status command, etc.), processing corresponding to the type of each command (the present invention and Since there is no relation, the details are omitted) (step S914). Thereafter, the process returns to step 901.

As described above, in the slot machine 1 according to this embodiment, there are two types of replay A and replay B as replay roles, and the display mode of both is different in the symbols derived to the right reel 3R. However, the symbols derived from the left and middle reels 3L and 3C are the same. In addition, as the number of determination values in the normal gaming state, those for which both the regular bonus, the big bonus (1) or the big bonus (2) and the replay B are subject to lottery are registered. When both are won, the derivation of Replay B is prioritized.
As described above, the replay B may be a lottery target even in the normal gaming state, but when this display mode is derived to the variable display device 2, the regular bonus, the big bonus (1), or the big bonus Since the probability of winning either of the bonuses (2) is high, it is possible to increase the player's expectation and improve the interest of the game.

  In addition to the replay B that can be won at the same time as the regular bonus, the big bonus (1) or the big bonus (2) as a replay role, the replay A is also prepared, so that a certain probability from the viewpoint of suppressing shooting characteristics. Even if it is necessary to make a replay winning in the above, the winning probability of only Replay B may be lower than the certain probability. Actually, the winning probability of Replay B in the normal gaming state is (10 + 10 + 10 + 1) /16384≈528.5 including the case of overlapping winning with regular bonus, big bonus (1) or big bonus (2). The winning probability of Replay A is considerably higher than 2245 / 16384≈ 1 / 7.29.

  From another perspective, when replay B is won, the probability of winning the regular bonus, big bonus (1) or big bonus (2) is also (10 + 10 + 10) / (10 + 10 + 10 + 1) ≈1 / 1 .03, a very high probability. For this reason, when winning Replay B, not only can you expect to win regular bonus, big bonus (1) or big bonus (2), but the expectation will be quite high. It can enhance the feeling and improve the interest of the game.

  On the other hand, Replay A, which is won with a much higher probability than Replay B in the normal gaming state, will not win in the same game as regular bonus, big bonus (1) or big bonus (2). However, since the display modes of Replay A and Replay B are the same for the left and middle reels 3L and 3C, for example, at the stage where the left reel 3L and the middle reel 3C are stopped in this order (experience this In many cases, the game is progressed by pushing forward), and even if “JAC” common to both of them is tempered on the active line, whether replay A is finally derived or replay B is derived I do not understand.

  For this reason, even when the replay A required for making the replay winning probability equal to or higher than a certain probability from the viewpoint of suppressing the shooting property is won, the left and middle reels 3L, At the stage where 3C is stopped, the regular bonus, the big bonus (1) or the big bonus (2) can be expected to be won, and the fun of the game can be further improved.

  When the regular bonus, big bonus (1) or big bonus (2) is won, the gaming state is controlled to RT from the next game (regular bonus, big bonus (1) or big bonus (2) in the game). The winning probability of Replay B will be increased. In this way, the game state is controlled to RT, so that replay B wins frequently. As a result, the regular bonus, the big bonus (1) or the big bonus (2) can be selected not only by considering the Replay B winning in units of one game but also by considering the Replay B winning in units of multiple games. It can make a player expect, and can further improve the interest of the game.

  Further, when the replay B is won based on the display result of the variable display device 2, a continuous effect is continued on the liquid crystal display 4 from that time onward after two games (however, the regular bonus, the big bonus (1) or the big bonus ( Until winning the 2). This continuous performance allows the player to continuously expect regular bonus, big bonus (1) or big bonus (2) to be won not only in the game won in Replay B, but also in the subsequent games. The interest of the game can be improved.

  In addition to Replay B, there are also watermelons that can be won in duplicate with regular bonus, big bonus (1) or big bonus (2). The regular bonus, the big bonus (1), and the big bonus (2) are all roles that are missed depending on the operation timing of the stop buttons 12L, 12C, and 12R. Therefore, when winning the watermelon, the regular bonus, the big bonus (1) or the big bonus (2) was won, but the regular bonus and the big bonus (1) are determined by the operation timing of the stop buttons 12L, 12C, 12R. Alternatively, it can be considered that the big bonus (2) has been missed. This allows the player to expect regular bonus, big bonus (1) or big bonus (2) to be won not only in the game won in Replay B but also in the game won in watermelon. 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. In the role-specific table, for the cherry, watermelon, and bell that are determined as winning combinations in any gaming state, the storage address of the determination value number is registered for each bet number, and the determination value number according to the bet number Will be acquired.

  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, the cherry, watermelon, and bell internal lottery can be performed with the winning probability corresponding to the gaming state only 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. Furthermore, since the number of bets paid out in the 1st bet corresponding to the regular bonus is more than the number of bets paid out at the time of winning the bell, the player's expectation in the regular bonus is further enhanced. Interest can be improved.

  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 in 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 determined and determined for each winning combination.

  However, the random number for internal lottery acquired by the random number acquisition process is not used as it is from the random number generation circuit 115 by the sampling circuit 116 but is used after being processed by software. The random number generation circuit 115 generates a random number by updating at a high speed with the frequency of the pulse signal of the pulse generation circuit 115a. However, in the random number for internal lottery processed by software, the periodicity of the update is increased by the processing. It will be lost. Thereby, it is possible to prevent the player from hitting as much as possible by losing the periodicity of the random numbers for internal lottery and varying the values.

  Moreover, the frequency of the pulse signal generated by the pulse generation circuit 115a to update the values of the counters 115b and 115c of the random number generation circuit 115 is higher than the frequency of the operation clock of the CPU 111, and is not an integral multiple. For this reason, the update of the random number generated by the random number generation circuit 115 becomes difficult to synchronize with the processing performed by the CPU 111. In addition, by increasing the frequency of the pulse signal of the pulse generation circuit 115a, the update speed of the random number generated by the random number generation circuit 115 can be made extremely fast. For this reason, the effect of preventing aiming by the player is further enhanced.

  On the other hand, the processing of random numbers by software is performed by replacing the upper byte and lower byte of the random number extracted from the random number generation circuit 115 by the sampling circuit 116, masking the 15th and 7th bits, and then bit-shifting the upper byte. Good. Therefore, even for a relatively large random number of 16 bits (actually masked 14 bits), the load required for processing necessary to lose periodicity is not so large, and can be easily obtained. Can do. Since a large random number can be acquired in this way, the probability setting in the internal lottery can be finely performed.

  Further, in the slot machine 1 according to this embodiment, when an abnormality occurs in the data stored in the RAM 112, the RAM is controlled to an abnormal error state of the RAM, 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. is 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 applicable to the present invention will be described.

  In the above embodiment, the display mode of Replay A is “JAC-JAC-JAC”, the display mode of Replay B is “JAC-JAC-Bell”, and the symbols on the right reel 3R are different. It was. For this reason, when the left and middle reels 3L and 3C were stopped as the first and second reels, it was not known whether Replay A or Replay B was used in the “JAC” template, If the right reel 3R is first stopped as the second reel, it will be known by the stop of the second reel whether it will be replay A or replay B even if a replay is won. Therefore, the display mode of Replay B is “JAC-JAC-Bell”, “JAC-Bell-JAC”, and “Bell-JAC-JAC”, and the stop buttons 12L, 12C, and 12R are operated in any order. Regardless of whether or not it is made, “JAC” may be tempered until the stop of the second reel when Replay B is won.

  In the above embodiment, the regular bonus winning flag, the big bonus (1) winning flag, and the big bonus (2) winning flag accompanying the transition to the regular bonus or the big bonus are carried over after the next game if no winning occurs. However, the JACIN winning flag that accompanies the transition to the regular bonus is deleted only for the game regardless of whether or not a prize has been won. However, the JACIN winning flag can also be carried over after the next game until a winning occurs. Even when the gaming state is a small role game with a big bonus, a regular bonus lottery may not be performed separately from JACIN.

  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 determination values of a combination such as a regular bonus, a big bonus (1), and a big bonus (2) cannot exceed 255 in any game situation. . 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, the number of determination values acquired according to the set value or the like is sequentially added to the random number value for internal lottery. However, the number of determination values acquired in accordance with the set value or the like may be sequentially subtracted from the acquired internal lottery random value, and the subtraction result 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, the 15th and 14th bits of the random number for internal lottery are set to “0”, and the subtraction result overflows (here, the subtraction result is negative) It can be determined whether or not

  In the above embodiment, the internal lottery is performed by sequentially adding the number of determination values of the lottery target according to the game situation to the acquired random number for internal lottery, and when the addition result overflows The role was determined to be a winner. On the other hand, according to the number of determination values of each combination according to the game situation, using the winning determination table that determines the determination value for determining each combination as winning, the acquired internal lottery random value value It is good also as what performs an internal lottery by comparing with the determination value of each combination.

  Further, in the above embodiment, the number of determination values sequentially added to the random numbers for internal lottery wins both regular bonus, big bonus (1) or big bonus (2) and replay B or watermelon. There was a thing. That is, the special bonus lottery of the regular bonus, the big bonus (1) or the big bonus (2) and the non-special lottery of the replay B and watermelon are simultaneously performed with the same number of determination values. On the other hand, the lottery for special roles and the lottery for non-special roles may be performed separately.

  FIG. 16 is a diagram schematically showing a winning determination table used in this modification. FIG. 17 is a flowchart showing details of the lottery process in this modification. In the example shown in FIG. 16 and FIG. 17, it is assumed that there is no regular bonus lottery in the small role game in the big bonus, and other configurations and processes are the same as those in the slot machine 1 in the above embodiment. Shall.

  As shown in FIG. 16, the winning determination table includes a small role winning determination table (small role table) and a bonus winning determination table (bonus table) for each gaming state, which are stored in the ROM 113 in advance. Here, as shown in FIG. 16A, 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. 16 (a), the hatched range is a range where both the non-special role and the special role are won if the random value for internal lottery is a value within this range.

  On the other hand, when the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is carried over from the previous game and the gaming state is RT, as shown in FIG. Only the small role table (2) corresponding to RT is used and an internal lottery is performed. In the small role table (2) corresponding to RT, a part of the range that was lost in the small role table (1) is a range for winning the replay B. Even when the gaming state is a small bonus game in a big bonus or a regular bonus, as shown in FIGS. 16C and 16D, the small bonus tables (3), (3), ( Only 4) is used and an internal lottery is performed.

  In the lottery process shown in FIG. 17, the process of steps S1001 to 1003 and the point of shifting to the RAM abnormality error process when it is determined in step S1003 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 S503 in FIG. 11). Also, the reel control table selection process (step S1015) after the winning flag setting status is confirmed is the same as the lottery process (step S530 in FIG. 11) in the above embodiment.

  When it is determined in step S1003 that the set value is in the range of 1 or more and 6 or less, the small combination winning determination table prepared according to the current gaming state (normal, RT, regular bonus or small combination game) The winning determination table used for internal lottery is set (step S1004). Next, a determination value for winning each combination registered in the set small role winning determination table is sequentially compared with a random number value for internal lottery acquired in step S1001 (step S1005) and set. It is determined whether or not any combination registered in the small combination winning determination table has been won (step S1006). When any winning combination is won, the winning flag of the winning combination is set in the RAM 112 (step S1007), and the process proceeds to step S1008. If no winning combination is won, the process proceeds to step S1008.

  In step S1008, it is determined whether the current gaming state is a regular bonus or a big bonus depending on whether the regular bonus flag or the big bonus flag is set in the RAM 112. If the current gaming state is a regular bonus or a big bonus, the process proceeds to step S1015.

  If the current gaming state is neither a regular bonus nor a big bonus, the gaming state is RT and the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag in the RAM 112 is the previous game. Whether it has already been set is determined based on whether the RT flag is set in the RAM 112 (step S1009). Even when the gaming state is RT, the process directly proceeds to step S1015.

  If the gaming state is not RT, it means a normal gaming state. Here, the bonus winning determination table is set as a winning determination table used for internal lottery (step S1010). Next, the winning value of each combination registered in the set bonus winning determination table is sequentially compared with the internal lottery random value acquired in step S1001 (step S1011), and the set bonus is determined. It is determined whether or not any combination registered in the winning determination table is won (step S1012). If no winning combination is won, the process proceeds to step S1015.

  If any winning combination (here, regular bonus, big bonus (1) or big bonus (2)) is won, the winning flag of the winning combination is set in the RAM 112 (step S1013). Here, an RT flag is also set in the RAM 112, and unless the regular bonus, the big bonus (1) or the big bonus (2) is won in the game, the gaming state applied in the next game is set to RT (step) S1014). Then, the process proceeds to step S1015.

  In this way, separate winning determination tables are prepared for special roles and non-special roles, and the random number value for internal lottery corresponds to the value that wins the special role in the normal gaming state, and non-special roles In the case of corresponding to the winning value, the special combination and the non-special combination will be won simultaneously. In this example, even if the display result of the variable display device 2 becomes watermelon or replay B based on the watermelon winning flag or the replay B winning flag, there is a possibility that the player has also won the special role. 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, in the normal gaming state, the internal lottery is performed using both the small role winning determination table and the bonus winning determination table, but the special state winning flag is carried over from the previous game and the gaming state is set to RT. If the game state is a big bonus or a regular bonus due to winning a special role, an internal lottery may be performed using only the small role winning determination table. Thereby, the internal lottery in the normal gaming state can be performed by a simple process.

  In this 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 different random numbers were used. Also good. Refer to the small role winning determination table according to the value of the random number for internal lottery corresponding to the non-special role, determine whether or not the winning of cherry, watermelon, bell, replay A, replay B, It is only necessary to determine whether the regular bonus, the big bonus (1) and the big bonus (2) are won or not by referring to the bonus winning determination table according to the value of the random number for internal lottery corresponding to.

  In this modification, the winning determination table is used, and the lottery of each combination is performed by comparing the determination value registered in this table with the winning determination table. However, as in the above-described embodiment, A special combination and a special combination are separately added to a random number for internal lottery, and the determination value of each combination is sequentially added (may be subtracted), and when the combination overflows, it can be determined that the combination is won. However, in order to win the same determination value as in the case where the winning determination table of FIG. 16 is used, it is necessary to register a loss as a lottery target in the table. Further, the acquired random numbers for internal lottery may be saved for the special lottery before the non-special lottery is performed first.

  In the above embodiment, when the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is carried over from the previous game and the game state is RT, the internal lottery If the random number value for the game corresponds to the regular bonus, the big bonus (1) or the big bonus (2) and the judgment value corresponding to both the replay B or the watermelon, It was supposed to be, but it may be lost. In order to realize this example, the lottery process in FIG. 11 may be performed without performing the processes in steps S517 and S524.

  If the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is set in the previous game, the replay B winning flag or watermelon winning flag is duplicated. Less often set. For this reason, when the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is carried over, it is often possible to win early, so that the game can be smoothly advanced. , It will be possible to prevent the player's willingness to play due to the bonus not being awarded forever.

  In the above embodiment, in the winning combination table by gaming state, regular bonus + replay B, regular bonus + watermelon, regular bonus, big bonus (1) + replay B, big bonus (1) + watermelon, big bonus (1 ), Big Bonus (2) + Replay B, Big Bonus (2) + Watermelon, Big Bonus (2), Cherry, Watermelon, Bell, Replayed role was registered in this order. Any lottery may be performed in any order.

  For example, regular bonus + replay B, big bonus (1) + replay B, big bonus (2) + replay B, replay B, regular bonus + watermelon, big bonus (1) + watermelon, big bonus (2) + watermelon, It may be registered in the order of watermelon, cherry, bell, replay A, regular bonus, big bonus (1), big bonus (2). Thus, regardless of whether the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is already set, at least the replay B and the watermelon have the same determination value range. Therefore, for the replay B, watermelon, cherry, bell, and replay A that are sequentially subject to internal lottery, the determination value range that is won in the normal gaming state and the determination value range that is won in RT are the same. can do.

  In addition, in the modified examples of FIGS. 16 and 17, the special role lottery is performed after the non-special role lottery is performed first, but the non-special role lottery is performed after the special role lottery is performed. It is good.

  In the above embodiment, the only combination that can be won in the same game as the regular bonus, the big bonus (1), and the big bonus (2) as a special combination is watermelon in addition to Replay B. Of course, other small roles may be selected in the same game as the regular bonus, the big bonus (1), or the big bonus (2). When cherry is applied as such a combination, it is preferable that the ratio of winning a special combination when winning a watermelon is different from the ratio of winning a special combination when winning a cherry. Thereby, it is possible to give the player a sense of expectation that is different between when winning the “cherry” and when winning the “watermelon”, thereby improving the fun of the game.

  Further, the ratio of the regular bonus, the big bonus (1), and the big bonus (2) as special roles that can be won simultaneously when winning a watermelon may be different. That is, the number of determination values of regular bonus + watermelon, big bonus (1) + watermelon, big bonus (2) + watermelon may be different. The same applies to Replay B and Cherry.

  Here, for example, when the number of determination values of big bonus (1) + watermelon or big bonus (2) + watermelon is larger than the number of determination values of regular bonus + watermelon, when winning a watermelon, it is more The player can expect to win the big bonus (1) or the big bonus (2) with high value. In this way, when the player wins a watermelon, the player can be further improved in interest by giving the player a different sense of expectation regarding the difference in the types of special roles.

  In the above embodiment, when the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is set, the gaming state is controlled to RT, and the winning probability of Replay A is not changed. The winning probability of Replay B is assumed to be higher than the normal gaming state. On the other hand, even when the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is set, the winning probability may not be changed in both Replay A and Replay B. When the regular bonus winning flag, big bonus (1) winning flag, or big bonus (2) winning flag is set, instead of increasing the winning probability of Replay B, the winning probability of Replay A is lowered, The winning probability may not be changed.

  In the above-described embodiment, the regular bonus, the big bonus (1), and the big bonus (2) may be won independently, or may overlap with Replay B or watermelon. In some cases, Replay B and watermelon were also won separately, and in some cases, they were won in combination with regular bonus, big bonus (1) or big bonus (2). However, in the present invention, at least the regular bonus, the big bonus (1), the big bonus (2), and the replay B need only be included in the winning combination. When you win the regular bonus, big bonus (1) or big bonus (2), you must also win Replay B. When you win the replay B, you will always win the regular bonus, big bonus (1) or big bonus (2) It is also possible to win.

  In the above embodiment, when the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is set in the RAM 112, the replay A winning flag or the replay B winning flag is further set. In this case, the derivation of the replay A or the replay B that is not missed is completely prioritized and the replay A or the replay B is always won. However, when the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is set, the gaming state is controlled by RT, and the winning probability of Replay B becomes extremely high. There is a risk that the big bonus (1) or the big bonus (2) will not be won easily.

  Therefore, not only the reel control table that prioritizes the derivation of the replay A or the replay B over the derivation of the regular bonus, the big bonus (1) or the big bonus (2), but also the regular bonus, the big bonus (1) or the big bonus (2 ) Is prioritized over Replay A or Replay B, and the latter reel control table is also selected at a predetermined ratio (however, a lower ratio than selecting the former reel control table). It is good also as what to do.

  A reel control table that gives priority to the derivation of replay A or replay B over the derivation of regular bonus, big bonus (1) or big bonus (2) until the predetermined number of games elapses after the gaming state is controlled by RT. If you do not win the regular bonus, big bonus (1), or big bonus (2) even after a predetermined number of games have passed since the RT is controlled, select the regular bonus, big bonus (1), or big A reel control table that prioritizes the derivation of bonus (2) over the derivation of replay A or replay B may be selected.

  In the above embodiment, in the small game in the normal gaming state, RT, and big bonus, the game can be started only by setting 3 as the bet number. On the other hand, even in the small game in the normal gaming state, RT and big bonus, it is possible to start the game by setting 1 as the bet number, and further set 2 as the bet number. The game may be started.

  When 1 or 2 is set as the bet number in the small game in the normal gaming state, RT and big bonus, the winning probability of the small role in the internal lottery is lower than when 3 is set as the bet number In both cases, the number of medals to be paid out when winning a small role can be increased. For example, when 3 is set as the bet number in the small game in the normal gaming state, RT, and big bonus, the win probability of the bell is 1 / 4.6 and the number of payout medals is 8. When 1 or 2 is set, the winning probability of the bell may be 1 / 240.9 and the number of medals to be paid out may be 15. Furthermore, the winning probability of the bell and the number of medals to be paid out may be changed depending on whether the bet number is set to 1 or 2 (the winning probability is higher when the bet number is 2 and the number of payout medals). Is more likely with 1 bet).

  Further, in a slot machine that can set any one, two, or three betting numbers in the small game in the normal gaming state, RT, and big bonus, the number of determination values is common to 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. 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. When the number of determination values is individually stored according to the number of bets, the same determination value number may be stored individually or different determination value numbers may be stored individually.

  In the above embodiment, the reel control table is selected in advance based on the setting status of the winning flag, the stop position of the symbol is determined with reference to the reel control table when the reels 3L, 3C, 3R are stopped, and the stop The slot machine that stops the rotation of the reels 3L, 3C, and 3R by the table system that stops the reel at the position has been described as an example. In contrast, based on the current symbol position when the stop condition is satisfied and the setting status of the winning flag, pull-in control is performed so that the symbol of the winning symbol is aligned, or the symbol of the symbol that is not winning The present invention can also be applied to a slot machine that stops the rotation of the reels 3L, 3C, and 3R by a control method in which the removal control is performed so as not to be aligned.

  In the control method, when the operation of the stop buttons 12L, 12C, 12R is detected, the corresponding reels 3L, 3C, 3R are within the range of the maximum stop delay time of 190 milliseconds from the symbol displayed at that time ( It is determined whether or not there is a winning symbol having a winning flag set in a range of a total of five frames including the displayed symbol and the amount drawn. If there is a symbol for a role with a winning flag set (determined from the symbol of the role that is given priority for derivation in the case of duplicate winning), select the symbol for winning the winning combination and select the active line (already stopped) When there is a reel, the winning display mode can be derived together with the symbols on the reels that are stopped. Otherwise, a symbol for not winning any combination is selected and derived. That is, even when the stop of the reels 3L, 3C, 3R is controlled by this control method, it can be derived by stopping the symbols within the range of the maximum stop delay time after the operation of the stop buttons 12L, 12C, 12R is detected. The display mode corresponding to the setting status of the winning flag is derived as the display result of the variable display device 2.

  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.
