The game is controlled to an advantageous special game state (so-called big bonus or regular bonus).

  In addition, in recent years, there are cases in which an extremely large number of medals can be obtained in the special gaming state, and there is a problem that the player's gambling ambition is more than necessary. When the number of medals earned in (1) reaches a predetermined number, the special gaming state is ended.

  However, when the number of medals acquired in the special gaming state reaches a certain number, the number of medals that can be acquired in the special gaming state hardly varies when the special gaming state ends. Since there is a problem of lack of, there are provided a plurality of special display modes (combination of 7 with color and 7 with no color), and depending on the type of special display mode that triggered the transition to the special gaming state, In the case where the number of medals acquired as the end condition of the special gaming state is changed, for example, in the case of a big bonus in which a combination of 7 colored is transferred, 450 is set as the number of medals acquired as the end condition. However, in the case of a big bonus in which the combination of 7 without color is aligned, 300 is set as the number of medals to be the end condition. Slot machines have been proposed (e.g., see Patent Document 1).

With respect to the winning in which the judgment value data is stored, the storage capacity necessary for storing the judgment value data can be reduced. That is, it is possible to reduce the data amount of the judgment value data necessary for determining whether or not winning is allowed.
Note that storing the judgment value data individually according to the types of allowable stages does not necessarily mean that the judgment value data is stored individually for the number of types of allowable stages. If the judgment value data is not stored in common, the data is included in this. For example, when there are six types of allowable stages (first stage to sixth stage), the determination value data is allowed in the allowable stage even when the first to third stages are common and the fourth to sixth stages are common. Depending on the type, it is stored separately.
Further, the plurality of types of permissible steps that can be set by the permissible step setting means do not mean that the proportions at which the pre-determining means allows the occurrence of winnings must be different from each other in all types.

  The game control board 40 is composed of a microcomputer having a CPU 41a, ROM 41b, RAM 41c, and I / O port 41d. The main control unit 41 for controlling the game, random numbers in a predetermined range (0 to 16383 in this embodiment) are used. A random number generation circuit 42 for generating, a sampling circuit 43 for acquiring a random number from the random number generation circuit, and a switch detection circuit 44 for detecting a detection signal input from switches connected to the game control board 40 directly or via the power supply board 100 , A motor driving circuit 45 that controls the driving of the reel motors 32L, 32C, and 32R, a solenoid driving circuit 46 that controls the driving of the flow path switching solenoid 30, and a driving control of various displays and LEDs connected to the game control board 40. The power supply voltage supplied to the LED drive circuit 47 and the slot machine 1 to be monitored is monitored. An interruption detection circuit 48 that outputs a voltage drop signal indicating that to the main control unit 41 when a drop is detected. When the power is turned on or when an initialization command from the CPU 41a is not inputted, a reset signal is sent to the CPU 41a. A reset circuit 49 to be applied and other various devices and circuits are mounted.

  The CPU 41a 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 41b to perform processing related to the progress of the game. Each part of the control circuit mounted on the control board 41 is controlled directly or indirectly. The ROM 41b stores fixed data such as programs executed by the CPU 41a and various tables. The RAM 41c is used as a work area when the CPU 41a executes a program. The I / O port 41d inputs / outputs a control signal to / from each circuit connected via a signal input / output terminal included in the main control unit 41.

  As the RAM 41c, a DRAM (Dynamic RAM) is used, and a refresh operation is required to maintain the stored data contents. The CPU 41a is provided with a refresh register 41R (see FIG. 42) for performing this refresh operation. The refresh register 41R is composed of 8 bits, and the lower 7 bits are automatically incremented every time the CPU 41a fetches an instruction from the ROM 41b. The value is updated every execution time of one instruction. Is called.

  The random number generation circuit 42 is configured by a counter that counts up and updates the value every time a predetermined number of pulses are generated, as will be described later, and the sampling circuit 43 acquires the numerical value counted by the random number generation circuit 42. . The random number generation circuit 42 defines a range of numerical values to be counted for each type of random number. In this embodiment, 0 to 16383 is defined as the range. The CPU 41a sends an instruction to the sampling circuit 43 in accordance with the processing to acquire the numerical value indicated by the random number generation circuit 42 as a random number (this function is hereinafter referred to as a hardware random number function). Random numbers for internal lottery, which will be described later, are not used as they are extracted by the hardware random number function, but are processed and used by software. Details thereof will be described in detail. The CPU 41a also has a function of updating the numerical value of the specific address in the RAM 41c by the process associated with the above-described timer interrupt, and acquiring the updated numerical value as a random number (hereinafter, this function is referred to as a software random number function).

  The CPU 41a transmits various commands to the effect control board 90 via the I / O port 41d. A command transmitted from the game control board 40 to the effect control board 90 is sent in only one direction, and no command is sent from the effect control board 90 to the game control board 40. The transmission line of the command transmitted from the game control board 40 to the effect control board 90 is composed of a strobe (INT) signal line, a data transmission line, and a ground line, and is connected via the effect relay board 80. The game control board 40 and the effect control board 90 are not directly connected.

  The production control board 90 is connected to electrical components such as a liquid crystal display 51 (see FIG. 1), production effect LEDs 52, speakers 53 and 54, and reel LEDs arranged on the front door of the slot machine 1. The components are driven based on control by a later-described sub-control unit 91 mounted on the effect control board 90.

  Similar to the main control unit 41, the effect control board 90 includes a microcomputer having a CPU 91a, ROM 91b, RAM 91c, and I / O port 91d.

Like the CPU 41a of the main control unit 41, the CPU 91a has an interrupt function (including an interrupt prohibition function) such as a timer interrupt, and a program stored in the ROM 91b based on a command transmitted from the game control board 40. (Described later) is performed to perform various controls for producing effects, and each part of the control circuit mounted on the effect control board 90 is controlled directly or indirectly.

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

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

  In the slot machine 1 of the present embodiment, when the CPU 41a of the main control unit 41 detects a voltage drop signal, a power interruption interrupt process is executed. In the power interruption processing, the RAM 41c of the main control unit 41 stores destructive diagnosis data (5A (H) in this embodiment) in which any bit is 1, and is stored in all areas of the RAM 41c. The RAM parity adjustment data is calculated so that the RAM parity based on the data becomes 0, and stored in the RAM 41c. The RAM parity is a value calculated as an exclusive OR of values stored in each bit of the corresponding area (all areas in this embodiment) of the RAM 41c. Therefore, if the RAM parity based on the data stored in all areas of the RAM 41c is 0, the RAM parity adjustment data is 0, and the RAM parity based on the data stored in all areas of the RAM 41c is 1. In this case, the RAM parity adjustment data is 1.

  The CPU 41a calculates the RAM parity based on the data stored in all areas of the RAM 41c at the time of activation, confirms the value of the destructive diagnosis data, the RAM parity is 0, and the destructive diagnosis On the condition that the data value is also correct, the processing state of the CPU 41a is restored to the state before the power interruption based on the data stored in the RAM 41c, but when the RAM parity is not 0 (in the case of 1) or for destructive diagnosis If the data value is not correct, 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. Unlike the other error states, the RAM abnormal error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated, and a new set value is set in the setting change mode described above. It will not be released until

  In the slot machine 1 according to the present embodiment, as described above, the prescribed number of bets that can be set according to the gaming state is determined, and when the prescribed number of bets determined according to the gaming state is set. It is possible to start the game only in In this embodiment, as will be described later, there are a regular bonus, a small role game in a big bonus, and a normal gaming state as a gaming state. Among these, 1 is defined as the prescribed number of bets corresponding to the regular bonus. 3 is defined as the prescribed number of bets corresponding to the small role game. In addition, the normal gaming state is composed of a two-card betting game and a three-card betting game, of which two is defined as the prescribed number of bets corresponding to the two-card betting game. 3 is defined as the prescribed number. Therefore, when the gaming state is a regular bonus, the game can be started only when the betting number is set to 1, and when the gaming state is the small role game, when the betting number is set to 3. Only the game can be started. In addition, when the gaming state is the normal gaming state, the game can be started only when 2 is set as the betting number in the case of a two betting game. The game can be started only when 3 is set. In this embodiment, when a specified number of bets corresponding to the gaming state is set, all winning lines L1 to L5 are activated, and the specified number corresponding to the gaming state is If it is 1, all winning lines L1 to L5 are activated at the time when 1 is set as the bet number, and if the specified number according to the gaming state is 2, at the time when 2 is set as the bet number If all the winning lines L1 to L5 are activated and the specified number corresponding to the gaming state is 3, all the winning lines L1 to L5 are activated when 3 is set as the bet number. .

  In the slot machine 1 of this embodiment, when all the reels 2L, 2C, and 2R are stopped, if a combination of symbols called “combinations” is arranged on the activated winning line (hereinafter referred to as an effective line), Become. The type of winning combination is determined according to the game state, but it can be roughly divided into a small role with payout of medals and a replay that can start the next game without the need to set the number of bets. There are a game combination and a special combination with a transition of the game state. 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.

  Of the winning flags for each of the winning combinations, the winning flag for the small role and the replaying role is valid only in the game in which the flag is set and is cleared at the end of the game. Is valid until a combination of combinations permitted by the flag is completed, and is cleared in a game having a combination of combinations permitted. In other words, once the winning flag for the special role is won, even if the combination of the characters allowed by the flag cannot be aligned, the winning flag is not cleared and it is carried over to the next game. Become. However, as will be described later, the combination of JACIN among the special roles will always be aligned with the winning game, so it will not be carried over to the next game, only the winning flags of other special roles will be If the combination of allowed combinations is not complete, it will be carried over to the next game.

  FIG. 4A is a diagram showing a gaming state-specific combination table. The game state-by-game role table is stored in advance in the ROM 41b of the main control unit 41, and is used when determining a winning combination determined in the internal lottery and determining a winning combination determined in winning determination. Yes, the registered content of the role table classified by game state indicates a role determined according to the game state.

  The role in this slot machine 1 is JAC, Cherry, Watermelon, Bell as a small role, Replay as a replaying role, Big bonus (1), Big bonus (2), Regular bonus (1), Regular bonus as special roles (2) JACIN is defined.

  In the regular bonus game state, JAC, cherry, watermelon, and bell, which are small roles, are determined as winning roles, and are subject to lottery in the internal lottery in the regular bonus. In the small bonus game, which will be described later of the big bonus, cherry, watermelon and bell, which are small roles, and regular bonus (2), which is a special role, and JACIN are determined as winning roles. It is targeted. In the normal game state, small roles such as cherry, watermelon and bell, replay role replay, special roles big bonus (1), big bonus (2), regular bonus (1) are determined as winning roles. In the normal game state, the lottery is a lottery target.

  In this embodiment, in the regular bonus game state, in addition to cherry, watermelon and bell, JAC is defined as a small role for winning. However, in the regular bonus game state, a small role game or a normal game is also provided. Similarly to the state, only cherry, watermelon and bell may be determined as winning small prizes.

  The big bonus is awarded when a combination of “red 7-red 7-red 7” and a combination of “white 7-white 7-white 7” are arranged on any of the active lines in the normal gaming state. When the big bonus is won, the gaming state shifts to the big bonus.

  When it is necessary to distinguish the big bonus by “Red 7-Red 7-Red 7” and the big bonus by “White 7-White 7-White 7”, the big bonus (1) and the big bonus (2 ), Called Big Bonus (3). When it is necessary to distinguish between the big bonus transferred with the big bonus (1) and the big bonus transferred with the big bonus (2), they are called the super big bonus and the normal big bonus, respectively. And

  In the big bonus, a game called a small role game can be played. While the gaming state is a big bonus, if the big bonus is a super big bonus, a super big bonus (SBB) flag is set in the RAM 41c, and if the big bonus is a normal big bonus, a normal big bonus is in progress. A flag is set in the RAM 41c. If the big bonus is a super big bonus, it ends when the total number of medals paid out to the player in the big bonus reaches 465, and if it is a normal big bonus, the game is played in the big bonus. The process ends when the total number of medals paid out to the person reaches 350. In other words, the number of medals, which is the big bonus end condition, differs between the super big bonus and the normal big bonus, so the number of medals that can be expected to be different depends on whether it is a super big bonus or a normal big bonus. It becomes.

  The regular bonus is awarded when a combination of “BAR-BAR-BAR” is arranged on any of the active lines in the small role game and the normal gaming state. When the regular bonus is won, the gaming state shifts from the small role game or the normal gaming state to the regular bonus. The regular bonus ends when 12 games are consumed, or when 8 games are won (any kind of combination is possible), whichever comes first. While the game state is in the regular bonus, the regular bonus medium flag is set in the RAM 41c. In particular, when a regular bonus is won in the small role game, a regular bonus is provided during the big bonus, and the regular bonus medium flag is also set in the RAM 41c in addition to the super big bonus medium flag or the normal big bonus medium flag. When the total number of medals paid out to the player in the big bonus reaches 465 with the regular bonus in the super big bonus, or the medal paid out to the player in the big bonus with the regular bonus in the normal big bonus When the total number reaches 350, the regular bonus is terminated together with the big bonus.

  In addition, when it is necessary to distinguish between the regular bonus due to “BAR-BAR-BAR” in the normal gaming state and the regular bonus due to “BAR-BAR-BAR” in the small role game in the big bonus, the regular bonus (1) respectively. This is called regular bonus (2). In addition, the big bonus (1), the big bonus (2), the regular bonus (1), and the regular bonus (2) described above may be simply referred to as “bonus”.

  JACIN wins when a combination of “Watermelon-JAC-JAC” is available on any of the active lines in the small role game, but in a gaming state other than the small role game, even if this combination is available, JACIN wins. Not. When winning JACIN, the above-mentioned regular bonus is provided during the big bonus, and the regular bonus medium flag is also set in the RAM 41c in addition to the super big bonus medium flag or the normal big bonus medium flag. When the total number of medals paid out to the player in the big bonus reaches 465 with the regular bonus in the super big bonus, or the medal paid out to the player in the big bonus with the regular bonus in the normal big bonus When the total number reaches 350, the regular bonus is terminated together with the big bonus.

  JAC is awarded when the combination of “Bell-JAC-JAC” is aligned on the active line in the regular bonus. However, in the gaming state other than the regular bonus, even if this combination is aligned, JAC is not awarded. Cherry is awarded when the symbol “cherry” is derived to any of the active lines for the left reel 2L in any gaming state. A watermelon is awarded when a combination of “watermelon-watermelon-watermelon” is aligned on any of the active lines in any gaming state. A bell is awarded when a combination of “bell-bell-bell” is arranged on any of the active lines in any gaming state. The payout of medals when these small roles are won will be described later.

  Replay is awarded when a combination of “JAC-JAC-JAC” is available on any of the active lines in the normal gaming state, but this combination is used for regular bonuses and big bonuses (small-games and regular bonuses). Even if it is complete, it will not be a replay prize. When a replay is won, no medals are paid out, but the next game can be started without setting the number of bets again, so the number of bets that no longer need to be set in the next game (replay wins are subject to the normal gaming state) Therefore, the number of bets that need not be set is 2 or 3, which is substantially the same as the payout of 2 or 3 medals.

  Hereinafter, the internal lottery will be described. The internal lottery decides whether or not the winning of each winning combination is allowed before the display results of all the reels 2L, 2C and 2R are derived and displayed (actually, when the start switch 7 is detected). To do. In the internal lottery, first, a random number for internal lottery (an integer from 0 to 16383) is acquired as described later. Then, for each combination determined according to the gaming state, the acquired internal lottery random number, the bet number set by the player, and the set value set by the reset / setting switch 38 It is performed according to the number of judgment values for the combination.

  The reference of the combination according to the game state is performed according to the combination table according to the game state shown in FIG. When the gaming state is a regular bonus (including the case where it is provided during the big bonus), JAC, cherry, watermelon, and bell are sequentially read out as the internal lottery target roles, and the small state game in which the gaming state is in the big bonus When there is, the regular bonus (2), JACIN, cherry, watermelon, and bell are sequentially read out as the subject combination of the internal lottery. However, when the regular bonus winning flag (2) is set in the game before the previous game and the winning based on the flag is carried over, the regular bonus (2) and JACIN are eligible for internal lottery. There is no. When the gaming state is the normal gaming state, the regular bonus (1), the big bonus (1), the big bonus (2), cherry, watermelon, bell, and replay are sequentially read out as the internal lottery target roles. However, when the winning flag of the regular bonus (1), the big bonus (1), or the big bonus (2) is set in the game before the previous game, and the game is carried over without winning based on the flag, the regular bonus (1 ), Big Bonus (1) and Big Bonus (2) are not eligible for internal lottery.

  In the internal lottery, the number of determination values determined for the internal lottery target combination is sequentially added to the internal lottery random number, and when the addition result overflows, it is determined that the winning combination is won. When the winning is determined, the winning flag of the combination is set in the RAM 41c of the main control unit 41. The determination value number is read according to the storage address of the determination value number registered in the role-specific table stored in advance in the ROM of the main control unit 41.

  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 in one byte. Therefore, each determination value number is registered using a storage area of two bytes.

  The number of determination values for each combination is registered corresponding to the number of bets (BET) set by the player in the game. This is because even if they have the same combination, the winning probabilities may differ depending on the number of bets. In addition, the number of determination values according to the number of bets for each combination may be common regardless of the set value, or may be different depending on the set value. If the number of determination values is common regardless of the set value, a common flag is set (value is set to “1”).

  In the role-specific table, as shown in FIG. 4B, regular bonus (1), regular bonus (2), big bonus (1), big bonus (2), JACIN, JAC, cherry, watermelon, bell, A storage address for the number of replay judgment values is registered.

  The regular bonus (1) is a role that is subject to internal lottery in the normal gaming state, and the storage address of the judgment value number corresponding to the bet number 2 in the two-wager game and the bet number 3 in the three-wager game And the storage address of the number of judgment values corresponding to. For the regular bonus (1), the common flag is 1 corresponding to the bet number 2, and the storage address of the common determination value number is registered regardless of the set value, but the bet number 3 is corresponded. The common flag is 0, and the storage addresses for the number of determination values are individually registered according to the set value.

  Regular bonus (2) and JACIN are internal lottery targets only in the small bonus game in the big bonus, and the storage address of the number of judgment values corresponding to the bet number 3 in the small bonus game is registered. . The value of the common flag for this role is 1, and a storage address for a common number of determination values is registered regardless of the set value.

  The big bonus (1) and the big bonus (2) are roles that are the targets of internal lottery in the normal gaming state, and the storage address of the judgment value number corresponding to the betting number 2 in the two-wager game and the three-wager betting The storage address of the number of determination values corresponding to the number 3 of bets in the game is registered. For the big bonus (1) and the big bonus (2), the common flag is 1 corresponding to the bet number 2, and the storage address of the common determination value number is registered regardless of the set value. The common flag is 0 corresponding to the bet number 3, and the storage address of the determination value number is individually registered according to the set value.

  The JAC is a role that is subject to internal lottery only with the regular bonus, and the storage address of the number of determination values corresponding to the bet number 1 with the regular bonus is registered. 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.

  Cherry, watermelon, and bell are internal lottery targets in any of the regular bonus, small role game, and normal game state, and the storage address of the number of judgment values corresponding to the bet number 1 in the regular bonus And a storage address of a determination value number corresponding to 2 bets in the two-game betting game in the normal gaming state, and a determination value number corresponding to 3 bets in the three-game betting game in the small role game or the normal gaming state. The storage address is registered. For cherry and watermelon, the common flag is 1, and a storage address for the common number of determination values is registered corresponding to the number of bets regardless of the set value. For the bell, the common flag is 0, and the storage address of the number of determination values is individually registered according to the set value corresponding to each bet number.

  The replay is a role that is an object of the internal lottery in the normal gaming state, and the storage address of the determination value number corresponding to the betting number 2 in the two-sheet betting game and the determination corresponding to the betting number 3 in the three-sheet betting game The storage address of the number of 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, the number of medals to be paid out when winning each winning combination is registered in the role-specific table. However, only the JACs, cherries, watermelons, and bells, which are small roles, are the targets for paying out medals when winning a prize. Cherry and watermelon can be played when the number of bets is 1 (regular bonus), 2 (two-game betting game in the normal gaming state), or 3 (small-game, three-game betting game in the normal gaming state) The number of medals to be paid out is the same, but for Bell, when the number of bets is 1 or 2, that is, when the game state is a regular bonus or a two-game bet game in the normal game state, it is more than the other eight A large number of 15 medals will be paid out.

  The regular bonus (1), the regular bonus (2), the big bonus (1), the big bonus (2), and the winning of JACIN are accompanied by a transition of the gaming state and are not eligible for paying out medals. Replay does not involve the payout of medals, but since it is not necessary to insert medals used for setting the number of bets in the next game (always the normal gaming state), it is substantially the same as paying out two or three.

  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 41c of the main control unit 41 in the development model, and in the address area allocated to the ROM 41b in the main control unit 41 in the mass production model.

  For example, the addresses ADD + 14, ADD + 44, and ADD + 46 are addresses that are referred to regardless of the bet number and the set value when the target part of the internal lottery is the regular bonus (2), JACIN, and JAC, respectively. Regardless, 32, 4311, and 27 are acquired as the number of determination values, respectively.

  The address ADD + 0 is an address that is referred to regardless of the set value when the number of bets is 2, that is, in the two-game betting game in the normal gaming state, when the target character of the internal lottery is the regular bonus (1). Addresses ADD + 16 and ADD + 30 are set regardless of the set value when the number of bets is 2, that is, when the target for internal lottery is a big bonus (1) or a big bonus (2) in a two-game betting game in the normal gaming state. This address is referred to by

  The address ADD + 2 is an address that is referred to when the bet number is 3, that is, when the target for internal lottery is the regular bonus (1) and the set value is 1 in the three-game betting game in the normal gaming state. Sometimes, the value 31 stored here is acquired as the number of determination values. Addresses ADD + 4, ADD + 6, ADD + 8, ADD + 10, and ADD + 12 are each when the bet number is 3, that is, in the three-game betting game in the normal game state, the internal lottery target is a regular bonus (1) and the set value is 2-6 This is the address that is referenced when Regarding the regular bonus (1), when the number of bets is 3, the number of determination values is individually stored in accordance with the set value. However, since the same number of determination values is stored, in any set value The probability of winning the regular bonus (1) is the same.

  Addresses ADD + 18, ADD + 20, ADD + 22, ADD + 24, ADD + 26, and ADD + 28 each have a bet number of 3, that is, in the normal gaming state, the target for internal lottery is the big bonus (1) and the set value is 1. It is an address that is referenced when .about.6. Addresses ADD + 32, ADD + 34, ADD + 36, ADD + 38, ADD + 40, and ADD + 42 each have a bet number of 3, that is, in a three-game betting game in the normal gaming state, the internal lottery target role is a big bonus (2) and the set value is 1. It is an address that is referenced when .about.6. For the big bonus (1) and the big bonus (2), the number of judgment values referred to when the number of bets is 3 is individually stored according to the set value, and a different number of judgment values is stored. The winning probabilities differ depending on the set value.

  The address ADD + 48 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 character of the internal lottery is cherry. The address ADD + 50 is an address that is referred to regardless of the set value when the number of bets is 2, that is, in the normal gaming state two-bet game, when the internal lottery target role is cherry. The address ADD + 52 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 of the three betting game or the small role game, the internal lottery target role is cherry. The number of judgment values for cherry is registered according to the number of bets, but since the same value is registered, whether it is a regular bonus, a two-game betting game in a normal gaming state, or a normal gaming state Regardless of whether it is a three-card betting game or a small role game, the winning probability of cherry is the same. Also for the watermelon, the number of determination values is registered in the same manner at addresses ADD + 54, ADD + 56, and ADD + 58.

  The address ADD + 96 is an address that is referred to regardless of the set value when the number of bets is two, that is, in the two-game betting game in the normal gaming state, when the target character of the internal lottery is replay. The address ADD + 98 is an address that is referred to regardless of the set value when the bet number is 3, that is, in the three-game betting game in the normal gaming state, when the target character of the internal lottery is replay. The number of judgment values for replay is registered according to the number of bets, but since the same value is registered, the winning probability of replay regardless of whether it is a two-player betting game or a three-player betting game Are the same.

  Addresses ADD + 60, ADD + 62, ADD + 64, ADD + 66, ADD + 68, and ADD + 70 are addresses that are referenced when the number of bets is 1, that is, when the target character of the internal lottery is a bell and the set value is 1 to 6 in the regular bonus. is there. Since the same value is registered in each of the addresses ADD + 60 and ADD + 62, ADD + 64 and ADD + 66, and ADD + 68 and ADD + 70, the set value 1 and the set value 2, the set value 3 and the set value 4 and the set value are set at the regular bonus time. With 5 and the set value 6, the winning probability of the bell is the same.

  Addresses ADD + 72, ADD + 74, ADD + 76, ADD + 78, ADD + 80, and ADD + 82 are each when the number of bets is 2, that is, when the target for internal lottery is a bell and the set value is 1 to 6 in a normal two-game betting game This address is referred to by Since different values are registered in the addresses ADD + 72, ADD + 74, ADD + 76, ADD + 78, ADD + 80, and ADD + 82, in the two-game betting game in the normal gaming state, the winning probability of the bell differs depending on the set value. . Addresses ADD + 84, ADD + 86, ADD + 88, ADD + 90, ADD + 92, and ADD + 94 each have a bet number of 3, that is, in a three-game betting game or a small-combination game in a normal gaming state, and the set value is 1 It is an address that is referenced when .about.6. Since different values are also registered in the addresses ADD + 84, ADD + 86, ADD + 88, ADD + 90, ADD + 92, and ADD + 94, the winning probability of the bell in the three-game betting game or small role game in the normal gaming state depends on the set value. It will be different.

  FIGS. 6A, 6B and 7A, 7B are diagrams showing an example of the relationship between the value of the random number for internal lottery and the number of determination values of each combination and the winning combination. In FIG. 6 (a), when the player is in a three-game betting game in the normal gaming state, in FIG. 6 (b), when the player is in the two-game betting game in the normal gaming state, and in FIG. FIG. 7B shows an example when the player is in the regular bonus. FIGS. 6A, 6B and 7A, 7B show examples where the set value is 6, and both the regular bonus winning flag and the big bonus winning flag are set. An example is shown when there is not.

  For example, as shown in FIG. 6 (a), in the three-game betting game in the normal gaming state, the roles that are subject to the internal lottery are regular bonus (1), big bonus (1), big bonus (2), Cherry, watermelon, bell, and replay. With the setting value 6, the number of determination values is 31, 20, 20, 20, 96, 68, 3582, and 2245, respectively. First, the regular bonus (1), which is the target of the internal lottery, is won when 16353-16383, which results in an overflow of the addition result by adding 31 judgment value numbers, is acquired as a random number for internal lottery. It becomes.

  Next, the big bonus (1) that is the subject of the internal lottery is obtained by adding 51, which is the sum of the judgment value number 31 of the regular bonus (1) and the judgment value number 20 of the big bonus (1). The winning combination is obtained when 16333 to 16352, which will overflow, are acquired as random numbers for internal lottery. Similarly, Big Bonus (2) is obtained when 16293-16332 is obtained as a random number for internal lottery, Cherry is obtained when 16197-16292 is obtained as a random number for internal lottery, and Watermelon is obtained from 16129- When 16196 is acquired as a random number for internal lottery, Bell is when 14047-16128 is acquired as a random number for internal lottery, and replay is when 11802-14046 is acquired as a random number for internal lottery Each is determined to be a winner.

  The approximate winning probabilities calculated for each combination based on the number of judgment values are 1 for each of the regular bonus (1), big bonus (1), big bonus (2), cherry, watermelon, bell, and replay. /528.5, 1 / 819.2, 1 / 409.6, 1 / 170.1, 1 / 240.9, 1 / 7.9, and 1 / 7.3. When 0 to 11801 are acquired as random numbers for internal lottery, all combinations are lost.

  In addition, as shown in FIG. 6B, in the two-player betting game in the normal gaming state, the regular bonus (1), the big bonus (1), the big bonus (2), cherry, watermelon are the same as the three-player betting game. , Bell, and Replay are subject to internal lottery, but since the number of judgment values is 31, 80, 40, 96, 68, 3582, 2245, 16353-16383, 16273-16352, 16233-16272, 16137 When ˜16232, 16069-16136, 12487-16668, 10242-12486 are acquired as random numbers for internal lottery, it is determined that the winning is made. In addition, the approximate winning probabilities of the respective roles are 1 / 528.5, 1 / 204.8, 1 / 409.6, 1 / 17.01, 1 / 240.9, 1 / 4.6, 1 / 7.3. When 0-10241 is acquired as a random number for internal lottery, all combinations are lost.

  In addition, as shown in FIG. 7A, in the small role game, the regular bonus (2), JACIN, cherry, watermelon, and bell are subject to internal lottery, and the number of determination values is 32, 4311, 96, Since 68, 2082, 16352 to 16383, 12041 to 16351, 11945 to 12040, 11877 to 11944, and 9795 to 11876 are acquired as the random numbers for the internal lottery, it is determined that the winning is made. In addition, the approximate winning probabilities for each combination are 1/512, 1 / 3.8, 1 / 17.01, 1 / 240.9, and 1 / 7.9. When 0 to 9794 are acquired as random numbers for internal lottery, all combinations are lost.

  Further, as shown in FIG. 7B, in the regular bonus, JAC, cherry, watermelon, and bell are subject to internal lottery, and the number of determination values is 27, 96, 68, 15919. When 16383, 16261-16356, 16193-16260, 274-16192 are acquired as random numbers for internal lottery, it is determined that the winner is won. In addition, the approximate winning probabilities for each combination are 1 / 606.8, 1 / 17.01, 1 / 240.9, and 1 / 1.03. When 0 to 273 are acquired as random numbers for internal lottery, all combinations are lost.

  Next, acquisition of random numbers for internal lottery will be described in detail with reference to FIG. The random numbers for the internal lottery are obtained by extracting random numbers from the random number generation circuit 42 by the hardware random number function and processing them by software by the CPU 41a. Note that the least significant bit of the random number extracted from the random number generation circuit 42 or the processed random number is called the 0th bit, and the most significant bit is called the 15th bit.

  FIG. 8A is a block diagram showing the configuration of the random number generation circuit 42 in detail. As shown in the figure, the random number generation circuit 42 includes a pulse generation circuit 42a, a lower counter 42b, and an upper counter 42c. The lower counter 42b and the upper counter 42c are both 8-bit (1 byte) counters, the lower counter 42b is the 0th to 7th bits, and the upper counter 42c is a total of 16 bits from the 8th to 15th bits. The data signal is output.

  The pulse generation circuit 42a outputs a pulse signal at a frequency that is higher than the frequency of the operation clock of the CPU 41a and is not an integral multiple thereof (preferably relatively prime). The pulse signal output from the pulse generation circuit 42a is clocked into the lower counter 42b.

  The lower counter 42b 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 42a. Assuming that positive logic is applied, a logical value of H level corresponds to 1 and a logical value of L level corresponds to 0. In the case of negative logic, a logic value of 1 may be read as L level, and a logic value of 0 may be read as H level. When the level of the 0th bit data signal is inverted from H level to L level, that is, whenever the logic value of the 0th bit data signal changes from 1 to 0, the level of the 1st bit data signal is changed to H level. Inverted alternately with L level.

  Similarly, when the level of the (m−1) th bit data signal is inverted from the H level to the L level, that is, whenever the logic value of the (m−1) th bit data signal changes from 1 to 0, the mth bit data The signal level is alternately inverted between the H level and the L level. The carry signal is output every time the level of the seventh bit data signal changes from H level, that is, the logical value of the seventh bit data signal changes from 1 to 0. The carry signal output from the lower counter 42b is clocked into the upper counter 42c.

  The upper counter 42c 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 42b. 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 a 16-bit data signal in which the data signal of the lower counter 42b is the lower 8 bits and the data signal of the upper counter 42c is the upper 8 bits is 0 (0000h) every time the pulse generation circuit 42a 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 42.

  The sampling circuit 43 includes a latch circuit, and latches and latches a 16-bit data signal output from the random number generation circuit 42 at that time based on a sampling command (when the start switch 7 is operated) from the CPU 41a. Output the data signal. The CPU 41a extracts numerical data corresponding to the data signal input from the sampling circuit 43 via the I / O port 41d as a random number generated by the random number generation circuit. In the following description, the data signal output from the random number generation circuit 42 is described as a random number corresponding to the logical value.

  FIG. 8B is an explanatory diagram until the CPU 41a processes the random number extracted from the random number generation circuit 42 into a random number for internal lottery by software. The random number extracted from the random number generation circuit 42 is stored in a 16-bit general-purpose register 41GR included in the CPU 41a.

  When the random number extracted from the random number generation circuit 42 is stored in the general-purpose register 41GR, the CPU 41a uses the other general-purpose register or the work area of the RAM 41c to lower-order the bytes of the general-purpose register 41GR (value extracted from the lower-order counter 42b). And the value of the upper byte (the value extracted from the upper counter 42c) are exchanged.

  Next, the CPU 41a performs an OR operation with the value 8080h of the random number in which the upper byte and the lower byte are replaced with respect to the extracted random number. Since the processing work of the CPU 41a is 1 byte, the logical OR operation is actually performed sequentially on the upper byte and the lower byte. By this OR operation, the 15th bit and the 7th bit are always 1. Furthermore, the CPU 41a 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 41a acquires the value stored in the general-purpose register 41GR at this time as a random number for internal lottery, stores it in a predetermined area of the RAM 41c, and sequentially adds the number of determination values of each combination to this It becomes. 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 41a are prohibited from the extraction of random numbers from the random number generation circuit 42 to the end of processing. This is to prevent the contents of the general-purpose register 41GR from being rewritten in the interrupt processing routine when an interrupt is generated to the CPU 41a.

  Next, the arrangement of symbols on the reels 2L, 2C, and 2R and stop control will be described. As described above, the rotation of the reels 2L, 2C, and 2R is stopped within a drawing range within 4 symbols from when the stop switches 8L, 8C, and 8R are operated. The symbol to be stopped is selected according to the setting status of the winning flag, and the symbols of the winning combination in the drawing range of 4 symbols are aligned and stopped on the effective line set in each game. If you can, stop them all together. Symbols that have not been selected will be stopped in the range of 4 symbols.

  Here, as shown in FIG. 2, “watermelon”, “bell”, and “JAC” are arranged at intervals of 5 symbols or less on all of the reels 2L, 2C, and 2R, and the drawing range of 4 symbols Thus, the variable display device 2 can always be stopped at any position. In other words, when the winning flags of watermelon, bell, replay, JAC, and JACIN are set, the winning combination can always be won regardless of the operation timing of the stop switches 8L, 8C, and 8R by the player.

  Next, the control of the two-sheet betting game and the three-sheet betting game in the normal gaming state will be described. In the normal gaming state, the game is controlled to either a two-card betting game in which the prescribed number of bets is set to two or a three-card betting game in which the prescribed number of bets is set to three. As described above, the game can be started only when the prescribed number of bets is set, so in the two-sheet betting game, the game can be started only when two bets are set, and the three-sheet betting game Then, the game can be started only when 3 is set as the bet number.

  In the normal gaming state, the game is basically controlled by a three-card betting game. After the big bonus (regardless of whether it is a super big bonus or a normal big bonus), the game is switched to the normal gaming state. During the 100 games, the prescribed number of bets is set to 2 and is controlled by a two-sheet betting game. When the regular bonus (1) is won in a state where the two-game betting game is controlled, the game from that time until the regular bonus (1) is won is controlled by the two-game betting game. However, it is not counted as the number of games for the two-wager game. When the regular bonus based on the winning of the regular bonus (1) is completed and the normal gaming state is resumed, the two-bet game is controlled, and the number of remaining two-bet games is counted from that point. In other words, the two betting game is controlled for 100 games after the end of the big bonus, except for the game after the regular bonus (1) is won and the regular bonus based on the winning of the regular bonus (1) is ended. Will be. Then, when 100 games have elapsed after the end of the big bonus, the specified number of bets is set to 3 again, and the game returns to the 3-wafer game.

  In addition, even if the remaining number of two betting games remains, if the big bonus (1) or big bonus (2) is won in the middle of the game, the time after the end of the big bonus accompanying the winning The game will be controlled to a two-bet game over 100 games, and the remaining number of games of the two-bet game will not be added.

  The two-card betting game requires fewer medals to start the game than the three-card betting game, and, as shown in FIGS. 5 and 6, a big bonus (1), The ratio of winning the big bonus (2) is 1: 2 regardless of the set value, whereas the ratio of winning the big bonus (1) and the big bonus (2) in the two-player betting game is related to the set value. In the two-game betting game, the Big Bonus (1) and the Big Bonus (2) will be selected as the Big Bonus (1) with the transition to the Super Big Bonus that can be expected to win more medals. The ratio of playing is higher than that of the three-wager game. As shown in FIGS. 5 and 6, the combined probability of the winning probability of the big bonus (1) and the winning probability of the big bonus (2) in the three-wager game is 1 / 273.1 (when the setting value is 6). On the other hand, the combined probability of the winning probability of the big bonus (1) and the winning probability of the big bonus (2) in the two-bet game is 1 / 16.5, and in the two-bet game, the big bonus (1 ) And the combined bonus probability of the big bonus (2) are higher than in the three-wager game. Furthermore, as shown in FIG. 5 and FIG. 6, in the two-card betting game, the winning probability of the bell is higher than that in the three-card betting game, and as shown in FIG. The number of three betting games is eight, whereas in the two betting game, 15 more medals are paid out. In other words, by being controlled by the two-card betting game, the probability of winning the big bonus is higher than that of the three-card betting game, and the ratio of winning the big bonus (1) is higher than that of the three-card betting game. The medal payout rate is controlled to be higher than that in the three-card betting game.

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

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

  In the start-up process, first, the built-in device, peripheral IC, interrupt mode, stack pointer, etc. are initialized (Sa1), then the voltage drop signal detection data is acquired from the input port, and whether or not the voltage drop signal is input. That is, it is determined whether or not the voltage is stable (Sa2), and when the voltage drop signal is input, the process proceeds to a loop process in which no process is performed.

  If it is determined in step Sa2 that the voltage drop signal is not input, the values of the I register and IY register are initialized (Sa3). By the initialization of the I register and the IY register, the address of the interrupt table to be referred to when an interrupt occurs is set in the I register, and the reference address for referring to the storage area of the RAM 41c is set in the IY register. . These values are fixed values and are always initialized at startup.

  Next, access to the RAM 41c is permitted (Sa4), and it is determined whether or not the setting key switch 37 is in an ON state (Sa5). If the setting key switch 37 is not in the ON state in step Sa5, the RAM parity of all storage areas (including the unused area and the unused stack area) of the RAM 41c is calculated (Sa6). Is determined (Sa7). In the case of normal backup, adjustment data is stored so that the RAM parity becomes 0. Therefore, if the RAM parity is not 0 in step Sa7, the data stored in the RAM 41c is not normal. Then, the process proceeds to the RAM abnormality error process shown in FIG.

  If the RAM parity is 0 in step Sa7, it is further determined whether or not the destructive diagnosis data is normal (Sa8). When the backup is normally performed, the destruction diagnosis data is set in the RAM 41c. Therefore, when the destruction diagnosis data is not normal in step Sa8 (when the destruction diagnosis data is not a value stored at the time of power failure). In addition, the data in the RAM 41c is not normal, and the routine proceeds to the RAM abnormality error processing shown in FIG.

  In the RAM abnormality error process, as shown in FIG. 10, after the RAM abnormality error code is displayed on the game auxiliary display 12 (Sb1), the process proceeds to a loop process in which neither process is performed.

  If it is determined in step Sa8 that the destruction diagnosis data is normal, the data in the RAM 41c is normal. Therefore, after initializing the storage area of the RAM 41c that is not required for restoration (Sa9), Destructive diagnosis data is cleared (Sa10). Next, each register is restored to the state before the power interruption (Sa11), the interrupt is permitted (Sa12), and the process executed at the end before the power interruption is returned to.

  If the setting key switch 37 is in the ON state in step Sa5, all the storage areas except the used stack area in the storage area of the RAM 41c are initialized (Sa13), and then the set value work (in the RAM 41c). The value (0 at this time) stored in the area where the set value is stored is corrected to 1 (Sa14). Next, an interrupt is permitted (Sa15), and the setting change process shown in FIG. 11, that is, the setting change mode is entered (Sa16). After the setting change process is completed, the process proceeds to the game process.

  In the setting change process, as shown in FIG. 11, the set value stored in the set value work of the RAM 41c (the value of the set value work is corrected to 1 before the setting change process is entered. Is read (Sb1).

  Thereafter, the operation enters a state of waiting for detection of the operation of the reset / setting switch 38 and the start switch 7 (Sb2, Sb3). When the operation of the reset / setting switch 38 is detected in the step Sb2, the set value read in the step Sb1. 1 is added (Sb4), and it is determined whether or not the set value after the addition is 7, that is, whether or not the settable range is exceeded (Sb5). If the set value after the addition is not 7, After returning to the state of waiting for detection of the operation of the reset / setting switch 38 and the start switch 7 in the steps Sb2 and Sb3 again, if the set value after addition is 7 in the step Sb5, the set value is corrected to 1 (Sb6 ), The process returns to the detection waiting state for the operation of the reset / setting switch 38 and the start switch 7 in the steps Sb2 and Sb3.

  When the operation of the start switch 7 is detected in step Sb3, the changed set value selected at that time is stored in the set value work of the RAM 41c and the set value is confirmed (Sb7). Wait until the setting key switch 37 is turned off (Sb8). If it is determined in step Sb8 that the setting key switch 37 is OFF, the process returns to the flowchart of FIG. 9, and the process proceeds to game processing.

  As described above, in the startup process, when the setting key switch 37 is not in the ON state, it is determined whether the RAM parity is 0 or not, and whether or not the destructive diagnosis data is normal is stored in the RAM 41c. It is determined whether or not the stored data is normal. If the data in the RAM 41c is not normal, the process proceeds to a RAM abnormality error process. In the RAM abnormality error process, after the RAM abnormality error code is displayed on the game auxiliary display 12, the process proceeds to a loop process in which no process is performed, so that the progress of the game is disabled. Once the RAM abnormality error process is started, the game cannot be resumed even if the CPU 41a is restarted except when the setting key switch 37 is started even when the CPU 41a is restarted. ing.

  Once the RAM abnormal error state is entered, the setting key switch 37 is activated and all areas except for the used stack area of the RAM 41c are initialized. The game cannot be progressed until a new set value is selected and set by operating the setting switch 38. In other words, in the state that has shifted to the RAM abnormal error state, the state where the game cannot be progressed is released and the game is resumed on condition that a new set value is selected and set by operating the reset / setting switch 38. Is possible.

  FIG. 12 is a flowchart showing the control contents of the game process executed by the CPU 41a.

  In the game process, a BET process (Sd1), an internal lottery process (Sd2), a reel rotation process (Sd3), a reel stop process (Sd4), a winning determination process (Sd5), a payout process (Sd6), and a game end process (Sd7) ) Are executed in order, and when the game end process is completed, the process returns to the BET process again.

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

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

  In the reel rotation process in step Sd3, a process of rotating each reel 2L, 2C, 2R is executed. In this reel rotation process, the operation of the stop switches 8L, 8C, 8R is validated when all the reels 2L, 2C, 2R rotate at a constant speed.

  In the reel stop process in the step of Sd4, the player's operation of the stop switches 8L, 8C, 8R is detected, and the corresponding reels 2L, 2C, 2R corresponding to the fact that the stop condition of each reel 2L, 2C, 2R is satisfied. Execute the process to stop the rotation.

  In the winning determination process in step Sd5, when it is determined in step Sd4 that the rotation of all the reels 2L, 2C, and 2R has been stopped, a winning is determined according to the display result derived for each reel 2L, 2C, and 2R. A process of determining whether or not it has occurred is executed.

  In the payout process in step Sd6, when it is determined in step Sd5 that a winning has occurred, processing such as addition of credits and payout of medals is performed based on the number of payouts according to the win.

  In the game end process in the step of Sd7, a process for setting a gaming state in preparation for the next game is executed.

  13 to 15 are flowcharts showing the control content of the BET process executed by the CPU 41a in the step Sd1.

  In the BET process, first, the value of the BET counter in which the value of the bet amount is stored in the RAM 41c is cleared (Se1), and it is determined whether or not the game is a replay game (Se2). If a replay game flag indicating that a replay game is in progress is set in the RAM 41c and it is determined that the game is a replay game, the value of the BET counter is incremented by 1, and the bet set in the RAM 41c is set. Specified number of numbers (a stipulated number of bets determined according to the gaming state, set to 1 when in a regular bonus, set to 2 when in a two-game betting game in the normal gaming state, and the normal gaming state In the case of the three-game betting game and the small role game, 3 is set.However, only the normal gaming state is controlled by the replay game.), Whether or not the value of the BET counter is a specified number The process (Se3, Se4) is repeatedly executed until it is determined that the value of the BET counter is a predetermined number in the Se4 step. If the value of the BET counter is determined to be the specified number in flop stands in detecting the state of waiting for operation of the start switch 7 (Se5). When the operation of the start switch 7 is detected in this state, the BET process is terminated and the process returns to the flowchart of FIG.

  Further, if the game is not a replay game in the step of Se2, it is determined whether or not the value of the BET counter is a specified number by referring to the specified number of bets set in the RAM 41c (Se6), and the value of the BET counter is specified. If it is a number, it is further determined whether or not the value of the credit counter in which the credit value is stored in the RAM 41c is 50, which is the upper limit value (Se7). If the value of the BET counter is the prescribed number and the value of the credit counter is 50 in the steps of Se6 and Se7, the flow path switching solenoid 30 is turned off, and the medal flow path is set on the medal payout exit 9 side. If a new medal is not allowed to enter the route (Se8) and the BET counter value is not a prescribed number in the Se6 step, or if the credit counter value is not 50 in the Se7 step, the flow path is switched. The solenoid 30 is turned on, and a medal can be inserted using the medal flow path as a path on the hopper tank side (Se9).

  Next, it is determined whether or not the value of the credit counter is 0 (Se10). If the value of the credit counter is not 0, it is further determined whether or not an operation of the settlement switch 10 is detected (Se11). If the operation of the settlement switch 10 is detected, a control for driving the hopper motor 34 to pay out medals for the value stored in the credit counter, that is, a control for returning medals stored as credits is performed. After performing the process (Se12), the process returns to the step of Se6.

  Further, when the value of the credit counter is 0 in the step of Se10, or when the operation of the settlement switch 10 is not detected in the step of Se12, it is determined whether or not the inserted medal sensor 31 has detected the passage of the inserted medal. If the passage of the inserted medal is detected, the specified number of bets set in the RAM 41c is referred to determine whether or not the value of the BET counter is the specified number (Se14). If the value of the counter is not the specified number, the BET counter value is incremented by 1 (Se15), and the process returns to the step of Se6. If the value of the BET counter is the specified number in the step of Se14, the value of the credit counter is 50. (Se16), and if the value of the credit counter is 50, the process proceeds directly to the step of Se6. Ri, unless Nea 50 of the credit counter, after adding 1 to the value of the credit counter (SE17), the flow returns to step Se6.

  If the inserted medal is not detected in step Se13, the specified number of bets set in the RAM 41c is referred to determine whether or not the value of the BET counter is the specified number (Se18). If the value of the counter is a specified number, it is determined whether or not the operation of the start switch 7 is detected (Se19). If the operation of the start switch 7 is not detected, the process returns to the step of Se6 as it is. If the operation No. 7 is detected, the flow path switching solenoid 30 is turned off, and the insertion of a new medal is prohibited using the medal flow path as a path on the medal payout exit 9 side (Se20), and the BET process is ended. Then, the process returns to the flowchart of FIG.

  If the value of the BET counter is not a prescribed number in the step of Se18, it is determined whether or not the value of the credit counter is 0 (Se21). If the value of the credit counter is 0, the process returns to the step of Se6. If the value of the credit counter is not 0 in the step of Se21, it is determined whether or not the operation of the single BET switch 5 is detected (Se22). If the operation of the single BET switch 5 is not detected, MAXBET It is determined whether or not the operation of the switch 6 is detected (Se23). If the operation of the MAXBET switch 6 is not detected, the process returns to the step of Se6.

  If the operation of the single BET switch 5 is detected in the Se22 step, the credit counter value is decremented by 1 (Se24), the BET counter value is incremented by 1 (Se25), and the process returns to the Se6 step. . If the operation of the MAXBET switch 6 is detected in the step of Se23, the credit counter value is decremented by 1 until the credit counter value becomes 0 or the BET counter value reaches a specified number, and the BET counter When the value of the credit counter becomes 0 at the step of Se26 or when the value of the BET counter reaches the specified number at the step of Se29, the process of adding 1 to the value of Se6 (Se26 to Se29) is repeated. Return to step.

  As described above, the BET process waits until a prescribed number of bets according to the gaming state is set, and the operation of the start switch 7 is enabled by setting the prescribed number of bets according to the gaming state. The game is allowed to start.

  FIG. 16 is a flowchart showing the control contents of the internal lottery process executed by the CPU 41a in step Sd2.

  In the internal lottery process, first, a random number acquisition process, the details of which will be described later, is performed (Sf1). In this random number acquisition process, a random number value for internal lottery is acquired based on a random number generated by a random number generation circuit (not shown).

  Then, the set value stored in the set value work of the RAM 41c is read (Sf2), and whether or not the read set value is in the range of 1 to 6, that is, whether the set value stored in the set value work is an appropriate value. (Sf3), and if the read set value is not in the range of 1 to 6, the process proceeds to the RAM abnormality error process shown in FIG.

  If the setting value read in step Sf3 is in the range of 1 to 6, the combination registered as an internal lottery target in the combination table according to gaming state in FIG. 4A corresponding to the current gaming state. Are read in order (Sf4). It is determined whether or not the type of the read role is regular bonus (regular bonus (1) (2)), big bonus (big bonus (1) (2)), or JACIN (Sf5). In the case of regular bonus, big bonus, or JACIN, whether or not the regular bonus or big bonus winning flag has already been set in the RAM 41c in the previous game, and it is carried over without winning based on the winning flag. Determine (Sf6). If the type of the read combination is not regular bonus, big bonus, or JACIN, the process proceeds to Sf7 as it is.

  If the winning flag for the regular bonus or the big bonus has already been set, the process returns to the process of Sf4, and further, the next registered role in the gaming state-specific role table is read (regular bonus, big bonus, JACIN is Since it is registered first in the role table according to gaming state, the lottery process will not be ended with this.) Even if the type of the read combination is regular bonus, big bonus, or JACIN, if neither the regular bonus winning flag nor the big bonus winning flag is set, the process proceeds to Sf7.

  In Sf7, the BET number (the number of bets) set in the step of Sd1 is further read, and the setting status of the common flag is acquired in the combination table of FIG. 4B for the combination and the combination corresponding to the read BET number. To do. As a result, it is determined whether or not a common flag is set for the combination and the BET number (Sf8).

  If the common flag is set, the number of determination values stored in the address registered in the role-specific table of FIG. 4B is acquired for the role and the BET number (Sf9). Then, the process proceeds to Sf11. If the common flag is not set, the determination value number stored in the address registered in the role-specific table corresponding to the setting value read for the role and the BET number is acquired (Sf10). Then, the process proceeds to Sf11.

  In step Sf11, the number of determination values acquired in step Sf9 or Sf10 is added to the random number value for internal lottery, and the result of the addition is used as a new random number value for internal lottery. Here, it is determined whether or not an overflow has occurred when the number of determination values is added to the random number for internal lottery (Sf12). If an overflow occurs, the winning flag for the combination is set in the RAM 41c (Sf13). Then, the internal lottery process is terminated, and the process returns to the flowchart of FIG.

  If no overflow has occurred, it is determined whether or not there is a combination that has not yet been processed among the combinations determined for the internal lottery for the gaming state (Sf14). If there is a combination that has not yet been processed, the process returns to the process of Sf4, and the process continues with the next combination registered in the gaming state-specific combination table as the processing target. If there is no combination not to be processed, the internal lottery process is terminated and the process returns to the flowchart of FIG.

  As described above, in the internal lottery process, it is confirmed whether or not the set value stored in the set value work is an appropriate value. If the set value is not an appropriate value, the above-described RAM abnormality error process is performed. In the same manner as when the RAM data is determined not to be normal at the time of startup, a RAM abnormality error state occurs, and the progress of the game is disabled.

  Next, the random number acquisition process in step Sg1 will be described in detail based on the flowchart of FIG. In the random number acquisition process, first, interrupts are prohibited (Sg1). Next, a sampling command is output to the sampling circuit 43, the random number generated by the random number generation circuit 42 is latched, and the value of the latched random number is input from the I / O port 41d and extracted. The random number value extracted from the random number generation circuit 42 is stored in the general-purpose register 41GR (Sg2).

  Next, the lower byte value and upper byte value of the random number stored in the general-purpose register 41GR are exchanged with each other using the work area of the RAM 41c (Sg3). Next, the value of the random number stored in the general-purpose register 41GR is ORed with 8080h (Sg4). 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 41GR is acquired as a random number for internal lottery and stored in a predetermined area of the RAM 41c (Sg5). Then, after permitting the interrupt prohibited in the step of Sg1 (Sg6), the random number acquisition process is terminated and the process returns to the flowchart of FIG.

  FIG. 18 is a flowchart showing the control contents of the winning determination process executed by the CPU 41a in step Sd5.

  In the winning determination process, first, in correspondence with the current gaming state, the combinations registered as winning determination targets in the gaming state combination table of FIG. 4A are sequentially read (Sj1), and the combination of the reading combination Are aligned with the active line (Sj2). If the combination of the combination is not on the effective line, the process proceeds to Sj4. If the combination of the combination is on the effective line, a winning flag indicating that the combination has won is set in the RAM 41c ( The processing proceeds to Sj3) and Sj4.

  In the step of Sj4, it is determined whether or not there is a combination that has not been processed yet among the combinations determined as a winning determination target for the gaming state. If there is a combination that has not yet been processed, the process returns to the process of Sj1, and the process continues with the next combination registered in the gaming state-specific combination table as the processing target. If there is no combination not to be processed, the winning flag is referred to determine whether or not the replay has won (Sj5). If the replay has not won, the process proceeds to Sj7. If the replay has won, the replay is performed. A replay game in-progress flag indicating that a game is in progress is set in the RAM 41c (Sj6), and the process proceeds to Sj7.

  In step Sj7, the winning flag is referenced to determine whether or not the big bonus (1) has been won. If the big bonus (1) has not won, the process proceeds to Sj10, and the big bonus (1) is won. If so, a super big bonus medium flag indicating that a super big bonus is in progress is set in the RAM 41c, and the winning flag of the big bonus (1) is cleared (Sj8), and the medal in the big bonus is paid out in the RAM 41c. After initializing the value of the big bonus medium payout counter in which the total number is stored (Sj9), the process proceeds to Sj10.

  In step Sj7, the winning flag is referenced to determine whether or not the big bonus (2) has been won. If the big bonus (2) has not won, the process proceeds to Sj13, and the big bonus (2) is won. If so, the normal big bonus medium flag indicating that the normal big bonus is in effect is set in the RAM 41c, and the winning flag of the big bonus (2) is cleared (Sj11), and the medal payout in the big bonus is performed in the RAM 41c. After initializing the value of the big bonus medium payout counter in which the total number is stored (Sj12), the process proceeds to Sj13.

  In step Sj13, it is determined whether or not the regular bonus (including JACIN) has been won by referring to the winning flag. If the regular bonus has not been won, the process returns to the flowchart of FIG. 12, and the regular bonus has been won. Then, a regular bonus flag indicating that the regular bonus is in progress is set in the RAM 41c, and the regular bonus winning flag (JACIN winning flag if JACIN) is cleared (Sj14), and the number of regular bonus games in the RAM 41c is determined. After initializing the value of the regular bonus game counter stored and the value of the regular bonus winning counter storing the number of winnings in the regular bonus (Sj15), the process returns to the flowchart of FIG.

  19 and 20 are flowcharts showing the control details of the game end process executed by the CPU 41a in step Sd7.

  In the process at the end of the game, first, it is determined whether or not a bonus is in effect, that is, whether or not a regular bonus or a big bonus is in effect (Sk1). If the bonus is in progress, the values of various counters used during the bonus (the above-described big bonus medium payout counter, regular bonus game number counter, regular bonus medium winning counter) are updated (Sk2). Proceed to processing.

  In step Sk3, it is determined whether or not the game is a replay game. If the game is not a replay game, the process proceeds to Sk5. If the game is a replay game, the replay game in-progress flag set in the RAM 41c is cleared. (Sk4), the process proceeds to Sk5.

  In step Sk5, it is determined whether or not the game is in the super big bonus. If the game is in the super big bonus, whether or not the value of the big bonus medium payout counter is 465 or more, that is, the payout in the big bonus. It is determined whether or not the total number has reached 465 (Sk6), and if the Super Big Bonus is not in the Sk5 step or if the value of the Big Bonus Payout Counter is less than 465 in the Sk6 Step For example, if the value of the big bonus medium payout counter is 465 or more in the step of Sk6, the super big bonus medium flag set in the RAM 41c is cleared (Sk7) and the two-wager game is in progress. Is set in the RAM 41c to indicate that the two-game betting game is in progress (S 8), the number of remaining games two bet game set 100 as the two values of the bet game counter RAM41c stored (SK9), the process proceeds to SK10.

  In the step of Sk10, it is determined whether or not the game is in the normal big bonus. If the game is in the normal big bonus, whether or not the value of the big bonus medium payout counter is 350 or more, that is, the payout in the big bonus. It is determined whether or not the total number has reached 350 (Sk11). If the normal big bonus is not in the Sk10 step, or if the value of the big bonus medium payout counter is less than 350 in the Sk11 step. If the value of the big bonus medium payout counter is 350 or more in the step of Sk11, the normal big bonus medium flag set in the RAM 41c is cleared (Sk12). The flag is set in the RAM 41c (Sk13), and the RAM Set 100 as the two values of the bet game counter 1c (SK14), the process proceeds to SK15.

  In the step of Sk15, it is determined whether the game is in a regular bonus or a state in which the regular bonus is won, and the game is in a regular bonus or the regular bonus is won. If it is one of the states, the process proceeds to the process of Sk21. If the game is not a regular bonus and the regular bonus is not won, it is determined whether or not the game is in a two-wager game. Is determined (Sk16), and if the two-wager game is not in progress, the process proceeds to Sk21.

  If it is determined in step Sk16 that the game is a two-bet game, the value of the two-bet game counter is decremented by 1 (Sk17), and it is determined whether the value of the two-bet game counter is 0 (Sk18). If the value of the two-wager game counter is not 0, it is determined whether or not the big bonus (1) or the big bonus (2) is won (Sk19).

  If the value of the two betting game counter is 0 in the step of Sk18, or if it is determined that the big bonus (1) or big bonus (2) is won in the step of Sk19, the value of the two betting game counter The two-game betting game flag is cleared (Sk20), and the process proceeds to Sk21. If it is determined in step Sk19 that neither the big bonus (1) nor the big bonus (2) has been won, the process proceeds directly to the process of Sk21.

  In the step of Sk21, it is determined whether or not the game is in the regular bonus. If the game is in the regular bonus, whether or not the regular bonus end condition is satisfied, that is, the number of regular bonus games is 12 games. Or if the number of winnings in the regular bonus reaches 8 times, and if the regular bonus provided during the Super Big Bonus, the value of the big bonus medium payout counter is 465 or more, If it is a regular bonus provided during the normal big bonus, it is determined whether or not the value of the payout counter in the big bonus is 350 or more (Sk22). Regular bonus termination conditions are not met in the step Lever, the process proceeds to the SK24, if the end conditions are met in the regular bonus at step SK22, clear the regular bonus flag set in the RAM 41c (SK23), the process proceeds to SK24.

  In step Sk24, it is determined whether or not the next game is a regular bonus. If the next game is a regular bonus, the specified number of bets set in the RAM 41c is set to 1 (Sk25) and set in the RAM 41c. The winning flags other than the special combination are cleared (Sk29), the process at the end of the game is terminated, and the process returns to the flowchart shown in FIG. If the next game is not a regular bonus, it is determined whether or not the next game is a normal two-game betting game (Sk26). If the next game is a two-game betting game, it is set in the RAM 41c. The specified number of bets is set to 2 (Sk27), the winning flags other than the special combination set in the RAM 41c are cleared (Sk29), the process at the end of the game is terminated, and the process returns to the flowchart shown in FIG. If the next game is neither a regular bonus nor a two-game betting game in the normal gaming state, that is, if the next game is a three-game betting game in the normal gaming state or a small role game in the big bonus, it is set in the RAM 41c. The specified number of bets is set to 3 (Sk28), the winning flags other than the special combination set in the RAM 41c are cleared (Sk29), the process at the end of the game is terminated, and the process returns to the flowchart shown in FIG.

  As described above, in the slot machine 1 according to the present embodiment, in the normal gaming state, the game is controlled by the two-card betting game, and when the three-card betting game is controlled, and the prize that is the object of the lottery by the internal lottery. There is no change in the type of game, but the prescribed number of bets that will be allowed to start the game is “2”, and as a result, more of Big Bonus (1) and Big Bonus (2) The ratio of winning the big bonus (1) with the transition to the Super Big Bonus that can be expected to win medals is higher than the three-card betting game, and it is controlled by the three-card betting game or the two-card betting game. The number of medals that can be expected varies depending on whether the game is successful or not.

  Further, by controlling the two-bet game in the normal gaming state, the combined probability of the winning probability of the big bonus (1) and the winning probability of the big bonus (2) is higher than that of the three-bet game. Controlled by the game can increase the player's expectation for the occurrence of a big bonus.

  In addition, by controlling to the two-card betting game in the normal gaming state, when the bell wins, the number of medals is larger than the number of medals (8) awarded when the bell wins in the three-card betting game. (15) will be awarded, so the expectation for the occurrence of the big bonus (1) accompanying the transition to the super big bonus that can be expected to win more medals by being controlled by the two-wager game Can increase the number of medals that the player can earn.

  Furthermore, by controlling to a two-card betting game in the normal gaming state, when the bell wins, more medals are awarded than when the bell wins in the three-card betting game, and by internal lottery Since the winning probability of the bell is also increased, the number of medals that the player can acquire can be further increased by being controlled by the two-wager game.

  Further, in the normal gaming state, in the three-bet game, the prescribed number of bets allowed to start the game is “3”, whereas in the two-bet game, the game start is allowed. Since the specified number of bets is “2”, even if there is no change in the type of prize that is the subject of the lottery by the internal lottery, the difference in the gaming state becomes clear due to the difference in the number of bets allowed to start the game, The game is easy to understand.

  Also, in the two-bet game, the prescribed number of bets allowed to start the game is “2”, which is smaller than the prescribed number of bets “3” in the three-bet game, and is necessary for starting the game. Since the number of medals will be small, it will be controlled by a two-wager game, and the transition to the Super Big Bonus, which can be expected to win more medals while controlling the amount of decrease in gaming value The expectation for the occurrence of the big bonus (1) accompanied with the can be increased.

  In the present embodiment, the combined probability of winning the big bonus (1) and the winning probability of the big bonus (2) is higher than that of the three-wager game by controlling the two-game betting game in the normal gaming state. Big Bonus (1) with a transition to a Super Big Bonus that can be expected to win more medals out of Big Bonus (1) and Big Bonus (2) in at least two betting games It suffices if the ratio of winning is higher than that of the three-wager game.

  Further, in this embodiment, the number of medals awarded when the bell wins in the three-game betting game is controlled by the two-game betting game in the normal gaming state. However, the number of medals awarded when another small role wins is greater than the number of medals awarded when the small role wins in a 3-bet game. Also good. Furthermore, it is good also as a structure which the number of medals given in a two betting game increases about a some small combination rather than a three betting game.

  In addition, by controlling to the two betting game in the normal gaming state, the winning probability of the bell by the internal lottery is higher than that of the three betting game, but the winning probability of other small roles is higher than that of the three betting game. It is good also as composition which becomes. Furthermore, it is good also as a structure by which the winning probability in a 2 betting game becomes high rather than a 3 betting game about several small roles.

  Also, in this embodiment, after the end of the big bonus, the game shifts to a two-wager game, and after the big bonus ends, more medals out of the big bonus (1) and the big bonus (2). Since the percentage of winning the big bonus (1) with the transition to the super big bonus that can be expected to be won increases, the winning of the big bonus again after the end of the big bonus, that is, the big bonus is a so-called consecutive resort. By doing so, more medals can be obtained, so that the game characteristics can be further improved.

  In this embodiment, the two-bet game is controlled after the end of the big bonus. However, in the three-game bet game in the normal gaming state, two cards are obtained when a predetermined transition condition is satisfied. It may be possible to shift to a betting game, and in this way, a super big bonus that can be expected to win more medals without going through the big bonus in a state where it is controlled by a three betting game. Since the transition to the two-bet game in which the ratio of winning the big bonus (1) accompanied by the transition is increased, the expectation for the transition to the two-bet game can be increased.

  In addition, in the case of transitioning from a three-game betting game in a normal gaming state to a two-game betting game, a transition to a two-game betting game is triggered when a specific small role such as cherry is elected in the three-gambling game. It is preferable, and by doing so, it will be sure to shift to a two-card betting game by winning a specific small role, so it is easy to understand the transition opportunity from the three-card betting game to the two-card betting game Can be. In addition, even if a specific small role cannot be won, that is, even when a specific small role is missed because the timing for stopping the reels is poor, only a specific small role is won by internal lottery. Since the transition to the single betting game is made, the transition condition to the two betting game is not affected by the skill of the player.

  In addition, in the case of a three-card betting game, when a specific small role is elected, when shifting to a two-card betting game, the game is controlled to a two-card betting game over the prescribed number of games, just like after the end of the big bonus. However, the two-game betting game may be terminated and the three-card betting game will be terminated when a specific small role that triggered the transition to the two-card betting game is elected in the two-card betting game. It is preferable to make the transition, and by doing so, since the transition condition to the two-wager game and the termination condition are the same, the gameability can be easily understood.

  Further, in the slot machine 1 of the present embodiment, as a type of winning combination, a small role accompanied by paying out medals, a re-playing role that does not require consumption of medals for the number of bets in the next game, and a transition of the gaming state. A special role is provided. The special role is accompanied by a transition of the gaming state and depends on the gaming state at that time, so it cannot be said to be a basic role. The playability of slot machines is not just playing a game, but the player earns medals based on the game results, so the small role that involves paying out medals by winning a prize is the most basic role. It can be said. Here, there are JAC, cherry, watermelon, and bell as types of small roles, but in addition to JAC that wins with a small probability in the regular bonus, it is determined as the types of winning combinations in any gaming state. ing. In this way, by defining the basic small combination as a winning combination regardless of the gaming state, the gameability becomes easy for the player to understand.

  When a big bonus is won in the normal gaming state, the gaming state is shifted to a big bonus that is won with a relatively high probability of winning JACIN accompanied by the transition to the regular bonus (no wins are missed). The big bonus ends when the total number of medals paid out to the player in the big bonus reaches 465 (in the case of a super big bonus) or 350 (in the normal big bonus) regardless of the number of digested games. It has become. Here, in a game with a big bonus (including a small role game and a regular bonus), since replay is not defined as a target character for internal lottery, no replay is won. Replay does not reduce the number of medals held by the player, but does not accompany the payout of medals, and therefore does not affect the number of payout medals, which is a condition for ending the big bonus. In other words, even if you make a replay win during the big bonus, it will only increase the number of big bonus games unnecessarily, so by not defining the replay as a target for internal lottery in the big bonus, The game can be efficiently advanced without unnecessarily prolonging the state.

  In addition, in the regular bonus game state, a small role (especially a bell) is won with a high probability and a large number of medals can be obtained, so the player has high expectations for this. This regular bonus is transferred not only when winning a JACIN in a small role game but also when winning a regular bonus in a normal gaming state. For this reason, even when the player is in the normal gaming state, the player can be given a sense of expectation for the regular bonus, so that the interest of the game can be improved. Furthermore, in the regular bonus, in addition to cherry, watermelon, and bell, which are defined in the normal gaming state and small role game, JAC is also defined as a small role. Thereby, the player's sense of expectation in the regular bonus can be further increased, and the interest of the game can be improved.

  In addition, the display mode of JACIN for shifting the game state from the small role game to the regular bonus in the big bonus is configured by a combination of “watermelon-JAC-JAC” and is not used as a display mode of other roles. It is. In the regular bonus, in addition to cherry, watermelon, and bell small roles, the JAC display mode is also determined by a combination of “Bell-JAC-JAC” and is not used as a display mode for other roles. It is. For this reason, the relationship between the display mode derived as the display result of the reels 2L, 2C, and 2R and the winning combination is clarified, and the gameability becomes easy for the player to understand.

  In addition, the rotation of the reels 2L, 2C, and 2R is stopped within the range of the maximum stop delay time of 190 milliseconds after the operation of the stop switches 8L, 8C, and 8R is detected. Since it can be pulled in, the symbol to be stopped can be selected from a range of five symbols. Here, since the symbols “watermelon”, “bell” and “JAC” are always arranged at intervals of 5 symbols or less for each of the reels 2L, 2C and 2R, the watermelon constituted by these symbols, Bell, Replay, JAC, and JACIN will not miss out when they are elected. In particular, the bells in the regular bonus will be won with a very high probability of approximately 1 / 1.03, but this will not be missed, so the player will effectively hold on to the regular bonus. It becomes unnecessary, and it becomes possible to advance the game easily.

  As described above, the types of the roles subject to internal lottery for each gaming state are registered in the gaming state-specific role table, but the number of determination values for determining the winning probability of each role is an address referenced from the role-specific table. Stored in In the role table, the number of medals when a winning of each role occurs is also registered.

  In the role-specific table, the number of medals is registered according to the number of wagers. When a winning of cherry, watermelon, or bell occurs, the number of medals is set according to the number of wagers (although for cherry and watermelon, the result is The same number of medals is set). Here, the number of bets in the regular bonus is fixed at 1, and the number of bets in the two-game betting game in the normal gaming state is fixed at 2. However, in the small-combination game in the big bonus and the three-game betting game in the normal gaming state The number of bets is fixed at 3. As a result, an appropriate number of medals can be paid out according to the gaming state simply by acquiring the payout number according to the number of bets. Further, since it is not necessary to determine the gaming state when setting the number of medals, the processing steps in the winning determination process are simplified.

  In the role-specific table, for cherry, watermelon, and bell defined 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 according to the bet number The number is acquired (although, in the case of cherry and watermelon, the same determination value number is acquired as a result). Here, the number of bets in the regular bonus is fixed at 1, and the number of bets in the two-game betting game in the normal gaming state is fixed at 2. However, in the small-combination game in the big bonus and the three-game betting game in the normal gaming state The number of bets is fixed at 3. Thereby, the internal lottery of cherry, watermelon, and bell 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.

  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 set bet number and the address storing the number of judgment values referenced according to the set value is different, it is stored at a different address. In some cases, the number of determination values is the same.

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

  Here, even if the number of determination values adjusted by the simulation is the same regardless of the set value, the number of determination values is stored in the ROM 41b with the same address assignment as that 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.

  Moreover, the storage address of the judgment value number of each combination registered in the combination table varies depending on the number of bets (1 to 3), but is stored at different addresses such as cherry and watermelon. In some cases, the same number of determination values is used.

  In the development model, it is normal to perform simulation while finely adjusting the judgment value data according to the number of bets (the same as when the initial number of judgment values is different) There may be cases). Here, even if the number of decision values adjusted by the simulation becomes the same regardless of the number of bets, the number of decision values is stored in the ROM 41b with 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. In addition, when generating the winning determination table before the actual winning determination is performed, the loop processing is required twice. However, according to this embodiment, the loop processing in the lottery processing may be performed only once. Thus, the processing efficiency of the entire lottery process is high.

  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 42 by the sampling circuit 43 but is used after being processed by software. The random number generation circuit 42 generates a random number by updating at a high speed at the frequency of the pulse signal of the pulse generation circuit 42a. However, in the random number for internal lottery after processing by software, the periodicity of the update is increased by the processing. It will be lost.

  On the other hand, in the internal lottery, since the number of determination values corresponding to each combination is sequentially added to the random value for internal lottery, each combination is determined as winning as shown in FIGS. The random number value for the internal lottery to be set will be hardened. On the other hand, it is possible to prevent the player from aiming as much as possible by losing the periodicity of the random numbers for internal lottery by processing by software and varying the values.

  Moreover, the frequency of the pulse signal generated by the pulse generation circuit 42a for updating the values of the counters 42b and 42c of the random number generation circuit 42 is higher than the frequency of the operation clock of the CPU 41a, and is not an integral multiple. For this reason, it becomes difficult for the update of the random number generated by the random number generation circuit 42 to be synchronized with the process performed by the CPU 41a. In addition, by increasing the frequency of the pulse signal of the pulse generation circuit 42a, the update speed of the random number generated by the random number generation circuit 42 can be made extremely fast.

  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 42 by the sampling circuit 43, 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 present embodiment, specific 2 bits (15th and 7th bits in this embodiment) are masked out of 2 bytes (16 bits) of random numbers extracted from the random number generation circuit 42 by the sampling circuit 43. A 14-bit random number is obtained. In general, a general-purpose random number generation circuit outputs a 16-bit random number. However, as a range of random numbers used in the internal lottery, a 14-bit random number is sufficient, and a 16-bit random number is used. If acquired as it is, the range of random numbers is too large, so the amount of data stored in the role-specific table increases, the storage area of the ROM 41b is compressed, and the numerical value to be processed in the internal lottery is also This is because the load on the CPU 41a also increases because it increases.

  As described above, in this embodiment, a 14-bit random number obtained by masking a specific 2-bit among 2-byte (16-bit) random numbers extracted from the random number generation circuit 42 by the sampling circuit 43 is acquired. Even if an inexpensive general-purpose random number generation circuit is used, the storage area of the ROM 41b is not compressed, and the load on the CPU 41a is not increased.

  Further, in the slot machine 1 of this embodiment, when an abnormality occurs in the data stored in the RAM 41c, the RAM is controlled to an abnormal RAM error state, and the progress of the game is disabled. If it is controlled, the state in which the progress of the game is disabled will not be released unless the setting change mode is entered and the setting value is newly selected and set based on the setting changing operation. That is, even if an abnormality occurs in the data stored in the RAM 41c, it is not the setting value automatically set by the slot machine, but the setting value selected and set based on the setting change operation (generally, the setting change Since the operation is performed by an employee of the amusement store, it is ensured that the game is performed based on the setting value selected by the amusement store side), so that the fairness of the game can be achieved.

  Further, in this embodiment, when determining whether or not winning is allowed in the internal lottery process, the set value stored in the set value work of the RAM 41c is an appropriate value (a value in the range of 1 to 6). If not, it is not determined whether or not the winning is allowed with the probability based on the default setting value (for example, setting 1), but in this case as well, it is controlled to the RAM abnormal error state, and the progress of the game is progressed. If the game is disabled, the mode is changed to the setting change mode, and the setting value is not newly selected / 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 winning is allowed in the internal lottery process, 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 41c is abnormal in most cases when the control cannot be continued due to a malfunction such as a power failure or the CPU 41a running out of control. For this reason, in this embodiment, since it is determined whether or not the data is normal only when the CPU 41a is activated after recovering from these states, it is determined whether or not the data stored in the RAM 41c is normal. The determination can be made only in a situation where there is a high possibility that an abnormality has occurred in the data. That is, in a situation where there is a low possibility that an abnormality has occurred in the data, it is not necessary to perform the determination, and the load on the CPU 41a can be reduced.

  In the present embodiment, the RAM parity adjustment data is calculated and stored so that the RAM parity based on all the data in the RAM 41c becomes 0 in the power interruption processing, and is stored in all areas in the RAM 41c at the time of restoration. By determining whether or not the RAM parity calculated based on the stored data is 0, it is determined whether or not the data in the RAM 41c is normal. Therefore, the determination can be performed accurately and easily. .

  Further, in this embodiment, in the power interruption processing, before the RAM parity adjustment data is calculated, destructive diagnosis data (in this embodiment, 5A (H)) in which any bit is 1 is set to a predetermined value. At the time of recovery, in addition to determining whether or not the RAM parity is 0, it is also determined whether or not the data for destructive diagnosis is stored normally, and the RAM parity is 0 and the data is destroyed It is determined that the data in the RAM 41c is normal on the condition that the diagnostic data is also normal. Even if the data in the RAM 41c is not normal, if 00 (H) is stored in all the areas, it is determined as normal by the RAM parity determination at the time of startup. After storing the destructive diagnostic data with the bit set to 1, calculate and store the RAM parity adjustment data, and check the destructive diagnostic data in addition to determining the RAM parity at the time of recovery. Even when 00 (H) is stored in all areas at the time of recovery and the RAM parity is determined to be normal, the destruction diagnosis data does not match the value stored at the time of a power failure and is determined to be abnormal. Therefore, the abnormality of the RAM 41c can be determined more accurately.

  Further, in this embodiment, when an abnormality occurs in the data in the RAM 41c and the progress of the game is disabled, a setting value changing operation as a condition for canceling the disabled state of the game is effective. As a result of the transition to the setting change mode (setting change processing), all the areas except the used stack area of the RAM 41c are initialized, so that the initial data of the RAM 41c due to the occurrence of an abnormality And initialization of data associated with selection / setting of set values can be performed at once, and unnecessary processing can be omitted. Further, when the CPU 41a is activated, it is determined whether or not the setting key switch 37 is ON before determining whether the data in the RAM 41c is normal. At that time, the setting key switch 37 is ON. If it is determined that there is, the determination as to whether the data in the RAM 41c is normal is not performed, and the mode shifts to the setting change mode, where a new setting value is selected and set. It can be omitted.

  In this embodiment, the RAM 41c is initialized before proceeding to the setting change process. However, the RAM 41c may be initialized along with the transition to the setting change process. It may be performed later, or may be performed when the set value is confirmed in the setting change process. In this case, if the determined set value is changed, inconvenience arises, and initialization is performed except for the set value work in the RAM 41c.

  Further, in this embodiment, once controlled to the RAM abnormal error state, the game is disabled until the setting change process is performed. The RAM 41c may be initialized, the set value may be set to an initial value (for example, set value 1), and the game may be restarted by performing a reset operation in this state.

  Further, in this embodiment, when determining whether or not winning is allowed in the internal lottery process, the set value stored in the set value work of the RAM 41c is an appropriate value (a value in the range of 1 to 6). If not, the RAM abnormal error state is also controlled in this case, but the setting value stored in the setting value work of the RAM 41c is not an appropriate value (a value in the range of 1 to 6). In this case, it may be determined whether or not winning is allowed with a probability based on an initial value of the set value (for example, set value 1).

  Although the embodiments of the present invention have been described with reference to the drawings, the present invention is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. Needless to say.

  For example, in the above-described embodiment, the determination value number storage area uses a 2-byte area to store the determination value number in each case. Of course, in a general slot machine, the number of judgment values for special roles is not often set to exceed 255 in any gaming situation. As described above, 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.

  Further, in the above-described embodiment, some of the determination values that are common regardless of the set value are stored in common for all of the set values 1 to 6, but the number of determination values is related to the set value. Even common items can be individually stored for each of the setting values 1 to 6. Further, if the number of determination values is common regardless of the set value, all of them can be stored in common for all of the set values 1 to 6.

  Moreover, in the said Example, it was whether it memorize | stored in common with the whole setting value 1-6, or it memorize | stored separately with respect to each of the setting values 1-6 in the said Example. 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. The same applies to the number of determination values for the bet number. For example, the bet numbers 1 and 2 may be common and the bet number 3 may be individual.

  Moreover, in the said Example, the judgment value number referred according to the number of bets about the same combination in the same setting value was stored in a different address with respect to each of the number of bets (1-3). That is, for the same combination at the same set value, even if the number of judgment values referred to according to the number of bets is the same, it is stored separately, but the combination with the same winning probability regardless of the number of bets For the role that makes the determination value number storage address common, or for the role that makes the winning probability the same regardless of the setting value and the number of bets, the address of the determination value number storage address is made common In this way, by storing the number of determination values in common, it is possible to reduce the storage capacity required for that purpose.

  In the 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, but from the value of random number for internal lottery that acquired the acquired determination value number, Subtraction may be performed sequentially, and the result of the subtraction may be used as a new random value for internal lottery. 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 embodiment, in the internal lottery, the number of determination values of each combination according to the game situation is sequentially added to the acquired random number for internal lottery, and when the addition result overflows, the winning combination is won. It was supposed to be judged. On the other hand, a winning determination table in which a determination value for determining each combination as winning is determined for each game in accordance with the number of determination values for each combination according to the game situation, and the internal random number for internal lottery acquired It is good also as what performs an internal lottery by comparing this value with the determination value of each combination. In addition, a winning determination table in which determination values for determining each winning combination are stored in advance in the ROM 41b, and an internal lottery value is compared by comparing the acquired internal random number value with the determination value for each winning combination. It is also good to do

  Further, in the above embodiment, winning in the internal lottery is exclusive, and a plurality of winning combinations are not won simultaneously in one game. However, in the internal lottery, multiple types of winnings are won. For example, a configuration in which a special combination and a small combination can be won simultaneously in the internal lottery may be adopted.

  In this case, for example, there is a role-specific table for the small role and re-playing role in which data that can specify the range of determination values for determining the winning of the small role and re-playing role are stored, and the special role is won. A special role-specific table in which data that can determine the range of determination values to be determined is stored is stored, and in one internal lottery, for a random number for the same internal lottery, a small role and replay The lottery for the small role and the replaying role referring to the role-specific table for the role and the lottery for the special role referring to the role-specific table for the special role are separately performed, and From the data registered in the separate table and the special table for special roles, the range of judgment values that each small role, replaying role, and special role win independently, and the small role and special role are won in duplicate. By making it possible to specify the range of judgment values, special roles Small role may also be adapted to be elected at the same time.

  Also, data that can specify a range of judgment values corresponding to only special roles, data that can specify a range of judgment values corresponding to both special roles and small roles, a small role, or a replay When data that can specify the range of the judgment value corresponding to only the combination is registered, and in the internal lottery, the acquired random number for internal lottery is included in the range of the determination value corresponding to only the special combination If the special role only is judged and if it falls within the range of judgment values corresponding to both the special role and the small role, the special role and the small role will be judged and the small role or replaying role will be determined. In the case of being included in the range of the determination value corresponding to only a special combination and a small combination, it can be configured such that a special combination and a small combination can be won at the same time. In other words, it is possible to specify a range of judgment values for winning a small role, a replaying role, and a special role separately from a single role-specific table, and a range of judgment values for winning a small role and a special role in duplicate. By doing so, it is possible to adopt a configuration in which a special role and a small role can be won simultaneously.

  In the above embodiment, the entire high-order byte of the random number extracted from the random number generation circuit 42 is replaced with the low-order byte, and the entire low-order byte is replaced with the high-order byte. On the other hand, the data of a specific bit among the random number bits extracted from the random number generation circuit 42 is simply replaced with data of other bits (however, other than the masked seventh and fifteenth bits). Also good. Alternatively, the random number value extracted from the random number generation circuit 42 may be directly acquired as a random number for internal lottery. Further, it may be processed into a random number for internal lottery by a method different from the above embodiment.

  FIG. 21 is an explanatory diagram of a first modification of the processing until the CPU 41a processes the random number extracted from the random number generation circuit 42 into a random number for internal lottery by software. Also in the first modification, the random number extracted from the random number generation circuit 42 is stored in the 16-bit general-purpose register 41GR included in the CPU 41a.

  When the random number extracted from the random number generation circuit 42 is stored in the general-purpose register 41GR, the CPU 41a further extracts the value of the internal refresh register 41R as a processing random number. The CPU 41a adds the processing random number extracted from the refresh register 41R to the value of the upper byte of the general-purpose register 41GR (the value extracted from the upper counter 42c). The value of the lower byte of the general register 41GR (the value extracted from the lower counter 42b) is left as it is.

  Next, the CPU 41a performs an OR operation with the value of the general-purpose register 41GR, that is, a value obtained by adding a processing random number to the upper byte with 8080h. Furthermore, the CPU 41a 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 41a acquires the value stored in the general-purpose register 41GR at this time as a random number for internal lottery, and sequentially adds the number of determination values to this.

  FIG. 22 is an explanatory diagram of a second modification of the process until the CPU 41a processes the random number extracted from the random number generation circuit 42 into a random number for internal lottery by software. Also in this example, the random number extracted from the random number generation circuit 42 is stored in the 16-bit general-purpose register 41GR included in the CPU 41a.

  When the random number extracted from the random number generation circuit 42 is stored in the general-purpose register 41GR, the CPU 41a further extracts the value of the internal refresh register 41R as a processing random number. The CPU 41a adds the processing random number extracted from the refresh register 41R to the value of the upper byte of the general-purpose register 41GR (the value extracted from the upper counter 42c). The processing random number extracted from the refresh register 41R is also added to the lower byte value (the value extracted from the lower counter 42b) of the general-purpose register 41GR.

  Next, the CPU 41a performs a logical OR operation with the value of the general-purpose register 41GR, that is, the value obtained by adding the processing random numbers to the upper byte and the lower byte, respectively, with 8080h. Furthermore, the CPU 41a 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 41a acquires the value stored in the general-purpose register 41GR at this time as a random number for internal lottery, and sequentially adds the number of determination values to this.

  In the first and second modified examples described above, the value of the refresh register 41R is extracted as a random number for processing, and this is extracted from the high-order byte of the random number extracted from the random number generation circuit 42 (in the second modified example, further lower byte) ) To process random numbers. The random number processing applied here includes at least processing for adding a processing random number to the upper byte. Thereby, the variation of the random numbers for internal lottery can be increased, and the player can prevent the aiming as much as possible.

  Further, since the processing random numbers are extracted from the refresh register 41R, no special configuration is required as means for generating the processing random numbers. Moreover, the value of the refresh register 41R is updated every time the CPU 41a fetches an instruction, and the update interval is not constant. Therefore, a random number with high randomness can be extracted as a processing random number. And since the randomness of the processing random number is high, the randomness of the random number for internal lottery generated using the random number is also high.

  In the first and second modifications, the value extracted from the refresh register 41R is added to the upper byte (and the lower byte) of the random number extracted from the random number generation circuit 42. A value that is periodically updated by hardware or software may be added. Further, instead of adding a value extracted from the refresh register 41R (or a value replacing the refresh register 41R), a logical operation such as subtraction, logical sum, or logical product may be performed.

  Further, bit replacement such as replacement of the upper byte and the lower byte shown in the above embodiment may be used in combination with the first and second modifications. Also in the first and second modified examples, the interrupt to the CPU 41a is prevented in order to prevent the contents of the general-purpose register 41GR from being rewritten between the extraction of the random number from the random number generation circuit 42 and the end of the processing. It will be prohibited.

  Further, in the second modification, processing random numbers to be added to the upper and lower bytes of the random number extracted from the random number generation circuit 42 may be separately extracted from the refresh register 41R at different timings. Separately prepare the processing random number to be added to the upper byte and the processing random number to be updated to the lower byte. Means for extracting may be provided. In this case, one of the means for updating the processing random number for the upper byte and the means for updating the processing random number for the lower byte can be constituted by the refresh register 41R.

  In the above embodiment, the case where the present invention is applied to the case where the random number generated by the random number generation circuit 42, that is, the random number extracted by the hardware random number function is processed by software has been described. However, the random number processing by the software described above may be applied to random numbers that are periodically updated by software. For example, the CPU 41a sends an instruction to the second microcomputer to extract a random number periodically updated by a timer interrupt or the like in a second microcomputer different from the microcomputer constituting the main control unit 41, and I The data can be input to the CPU 41a via the / O port 41d and stored in the general-purpose register 41GR. The function of the second microcomputer may be included in the microcomputer that constitutes the main control unit 41. Also in this case, the random number value obtained after the processing can be varied, and the effect of preventing the player from aiming can be achieved.
