There are a game combination and a special combination with a transition of the game state. Of each combination determined according to the gaming state, in order to win a special combination and a re-playing combination, it is necessary to win an internal lottery to be described later and set a winning flag for the combination . In addition, for a small role, depending on whether it is a normal gaming state, a small role game and a regular bonus, which will be described later, or a CTBB and 1GCT, a prize for a small role occurs in the normal gaming state, the small role game and the regular bonus. In order to do so, it is necessary to win an internal lottery to be described later, and the winning flag for the winning combination must be set. However, in order to win a small winning combination in CTBB and 1GCT, It does not need to be set. This is because winning of all small roles is permitted by a later-described CTBB flag set in the RAM 41c during CTBB and a later-described 1GCT flag set in the RAM 41c during 1GCT.

  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 1GCT and JACIN among the special roles will always be aligned with the winning game, so it will not be carried over to the next game, regular bonus (1), regular bonus (2) Only the winning flag of Big Bonus and CTBB will be carried over to the next game if the combination of combinations allowed by the flag is not complete.

  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.

  Roles in this slot machine 1 are JAC, Cherry, Bell, Bell B as small roles, Replay as replaying roles, Regular bonus (1), Regular bonus (2), Big bonus, Challenge time / Big as special roles Bonus (hereinafter referred to as CTBB), one game challenge time (hereinafter referred to as 1 GCT), and JACIN are defined.

  In addition, as shown in FIG. 4A, a combination of symbols corresponding to each type of role is registered in the gaming state-specific combination table, and values 0 to 3 are registered for each gaming state. Of these, a game state in which 0 is registered indicates that the combination is not a target combination for either internal lottery or winning determination, and in a gaming state in which 1 is registered, the combination is subject to internal lottery or winning determination. In the gaming state in which 2 is registered, indicating that both of the winning combinations are registered, it is indicated that the winning role is a target role for internal lottery only, and in the gaming state in which 3 is registered, the winning combination is determined to be a prize. Indicates that it is the only target role.

  In the regular bonus game state, JAC, Cherry, Bell, and Bell B, which are small roles, are determined as winning roles, and all of these roles are determined as roles to be selected in the internal lottery. . In the small bonus game described later of the big bonus, the regular bonus (2) and JACIN, which are special roles, and cherry, bell and bell B, which are special roles, are defined as winning roles, and all these roles are internal. In the lottery, it is defined as the role that will be the subject of the lottery. In the gaming state of CTBB, small roles such as Cherry, Bell, and Bell B are determined as winning roles, and the special bonus Regular Bonus (1) is determined as a target to be selected in the internal lottery. Yes. In the gaming state of 1 GCT, small roles such as cherry, bell and bell B, and replaying replays are defined as winning roles. Regular bonuses (1), big bonus and CTBB, A replay as a game combination is defined as a combination to be selected in the internal lottery. In the normal gaming state, the regular bonus (1), big bonus, CTBB and 1GCT, which are special roles, cherry, bell and bell B, which are small roles, and replay which is a replaying role, are determined as winning roles. All of these combinations are defined as combinations that are subject to the lottery in the internal lottery.

  In this embodiment, in the regular bonus game state, in addition to cherry, bell and bell B, JAC is defined as a small role for winning. However, in the regular bonus game state, Similarly, only the cherry, bell, and bell B may be determined as small winning combinations.

  The big bonus is awarded when a combination of “red 7-red 7-red 7” is 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. In the big bonus, a game called a small role game can be played. While the game state is the big bonus, the big bonus medium flag is set in the RAM 41c. The big bonus ends when the total number of medals paid out to the player in the big bonus reaches 345.

  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 described later. 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. Further, when the total number of medals paid out to the player in the big bonus reaches 345 with the regular bonus provided during the big bonus, 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). Further, the big bonus, the regular bonus (1), the regular bonus (2), and the CTBB described above may be collectively referred to as “bonus”.

  JACIN wins when a combination of “JAC-JAC-Watermelon” 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 big bonus medium flag. When the total number of medals paid out to the player during the big bonus reaches 345 with the regular bonus provided during the big bonus, the regular bonus is terminated together with the big bonus.

  CTBB is awarded when a combination of “white 7-white 7-white 7” is aligned on any of the active lines in the normal gaming state. When CTBB wins, the gaming state shifts to CTBB. In CTBB, a game called a challenge time game (hereinafter referred to as a CT game) can be played. While the gaming state is in CTBB, the CTBB in-progress flag is set in the RAM 41c. The CTBB ends when the total number of medals paid out to the player in the CTBB reaches 253 or when the regular bonus (1) is won, whichever comes first.

  1GCT is awarded when a combination of “watermelon-watermelon-watermelon” is arranged on any of the active lines in the normal gaming state. When 1GCT is won, the gaming state shifts to 1GCT. In 1 GCT, only one CT game described above can be played. While the gaming state is 1GCT, the 1GCT in-progress flag is set in the RAM 41c.

  JAC is awarded when the combination of “JAC-JAC-Bell” is aligned on the active line in the regular bonus. However, in the gaming state other than the regular bonus, JAC is not awarded even if these combinations are aligned. 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 bell is awarded when a combination of “bell-bell-bell” is arranged on any of the active lines in any gaming state. Bell B wins when the combination of “Bell-Bell-BAR” is aligned on any of the active lines in any gaming state. The payout of medals when these small roles are won will be described later.

  Replays are awarded when a combination of “JAC-JAC-JAC” is placed on either of the active lines in the normal gaming state and 1 GCT, but in regular bonuses and big bonuses (small game and regular bonus), CTBB Even if this combination is complete, it will not be a replay prize. When a replay win is made, no medals are paid out, but the next game can be started without setting the bet amount again. Therefore, the bet number that does not need to be set in the next game (regular bonus does not cause a replay win and 1GCT Even if a replay is won, the next game will be in the normal gaming state, so it will be always 3), which is substantially the same as the payout of 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, as will be described later, a random number for internal lottery (an integer from 0 to 16383) is acquired. 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 the bonus is provided during the big bonus), JAC, cherry, bell, and bell B are sequentially read out as the internal lottery target roles, and the gaming state is a small role in the big bonus. When in the game, the regular bonus (2), JACIN, cherry, bell, and bell B are sequentially read out as the subject combinations for 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 CTBB, only the regular bonus (1) is read out as a target combination for internal lottery. When the gaming state is 1 GCT, the regular bonus (1), big bonus, CTBB, and replay are sequentially read out as the subject combination of the internal lottery. When the gaming state is the normal gaming state, the regular bonus (1), big bonus, CTBB, 1GCT, cherry, bell, bell B, and replay are sequentially read out as the subject combinations of the internal lottery. However, when the regular bonus winning flag (1), the big bonus winning flag or the CTBB winning flag 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 , CTBB and 1GCT 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 with the same combination, the winning probability in regular bonus, CTBB, and 1GCT may be different from other combinations. 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 table, as shown in FIG. 4 (b), regular bonus (1), regular bonus (2), big bonus, CTBB, 1GCT, JACIN, JAC, cherry, bell, bell B, replay judgment value Numbers of storage addresses are registered in the order in which they are referenced.

  Regular bonus (1) is a role that is subject to internal lottery in the normal gaming state, CTBB and 1GCT, the storage address of the judgment value number corresponding to the betting number 1 in CTBB and 1GCT, and the betting in the normal gaming state A storage address of the number of determination values corresponding to Equation 3 is registered. For the regular bonus, the common flag is 1 corresponding to the bet number 1, and the storage address of the common determination value number is registered regardless of the set value. Is 0, and 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 judgment value corresponding to the bet number 3 in the small bonus game is registered. . The value of the common flag for this combination is 1, and a common storage address for the number of determination values is registered regardless of the set value.

  1GCT is a role that is subject to internal lottery only in the normal gaming state, and a storage address of the number of determination values corresponding to the bet number 3 in the normal gaming state is registered. The value of the common flag for this combination is 0, and the storage addresses for the number of determination values are 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, Bell, and Bell B are internal bonus draws in regular bonus, small role game, and normal gaming state, and the storage address of the number of judgment values corresponding to the number of bets 1 in the regular bonus, and the small role game Alternatively, the storage address of the number of determination values corresponding to the bet number 3 in the normal gaming state is registered. For Cherry and Bell B, 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.

  Replay is a role that is subject to internal lottery in the normal gaming state and 1 GCT, the storage address of the determination value number corresponding to 1 bet in 1 GCT, and the determination value number corresponding to 3 bets in the normal gaming state Storage address 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. Of course, only the JAC, Cherry, Bell, and Bell B, which are small roles, are the targets for paying out medals when winning a prize. Cherry, Bell, and Bell B can be awarded when the number of bets is 1 (regular bonus, CTBB, 1GCT) or 3 (small role game, normal gaming state). When the number is 1, that is, when the gaming state is a regular bonus, CTBB, or 1GCT, 15 medals that are more than the other 5 are paid out.

  The regular bonus (1), regular bonus (2), big bonus, CTBB, 1GCT, and JACIN wins are accompanied by a shift in the gaming state and are not eligible for payout of medals. The replay does not involve the payout of medals, but it is substantially the same as the payout of 3 medals since it is not necessary to insert medals used for setting the bet amount in the next game (always the normal gaming state).

  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 + 56, and ADD + 58 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, 21, 4311 and 12363 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 1, that is, when the subject in the internal lottery is a regular bonus (1) in CTBB or 1GCT. The addresses ADD + 16 and ADD + 30 are addresses that are referred to regardless of the set value when the number of bets is 1, that is, when the target of the internal lottery is a big bonus or CTBB in 1 GCT.

  The address ADD + 2 is an address that is referred to when the number of bets is 3, that is, in the normal game state, when the target character of the internal lottery is the regular bonus (1) and the set value is 1, and is stored here. The obtained value 1000 is acquired as the number of determination values. The addresses ADD + 4, ADD + 6, ADD + 8, ADD + 10, and ADD + 12 are referred to when the bet number is 3, that is, when the target character of the internal lottery is a regular bonus (1) and the set value is 2 to 6 in the normal gaming state Address. 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 are referred to when the number of bets is 3, that is, when the target for internal lottery is a big bonus and the set value is 1 to 6 in the normal gaming state Address. Addresses ADD + 32, ADD + 34, ADD + 36, ADD + 38, ADD + 40, and ADD + 42 are addresses that are referenced when the number of bets is 3, that is, when the target combination of the internal lottery is CTBB and the set value is 1 to 6 in the normal gaming state It is. Addresses ADD + 44, ADD + 46, ADD + 48, ADD + 50, ADD + 52, and ADD + 54 are addresses that are referenced when the number of bets is 3, that is, when the target of the internal lottery is 1 GCT and the set value is 1 to 6 in the normal gaming state It is. For regular bonus (1), big bonus, CTBB, and 1GCT, the number of judgment values referred to when the bet number is 3 is individually stored according to the set value, and different judgment value numbers are stored. Therefore, the winning probabilities differ depending on the set value.

  The address ADD + 60 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 + 62 is an address that is referred to regardless of the set value when the bet number is 3, that is, in the normal gaming state or in the small role game, when the target character of the internal lottery is cherry. The number of judgment values for cherry is registered according to the number of bets, but since the same value is registered, the winning of cherry regardless of whether it is a regular bonus, a normal gaming state or a small role game Probability is the same. Regarding the bell B, the number of determination values is registered in the same manner at the addresses ADD + 88 and ADD + 90.

  The address ADD + 92 is an address that is referred to regardless of the set value when the bet number is 1, that is, when the target character of the internal lottery is replay in 1 GCT. The address ADD + 94 is an address that is referred to regardless of the set value when the bet number is 3, that is, when the target character of the internal lottery is replay in the normal gaming state. 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 is the same regardless of whether it is 1 GCT or the normal gaming state. .

  The addresses ADD + 64, ADD + 66, ADD + 68, ADD + 70, ADD + 72, and ADD + 74 are addresses that are referred to when the bet number is 1, that is, when the target character of the internal lottery is a bell and the set value is 1 to 6 in the regular bonus. is there. Since the same values are registered in the addresses ADD + 64 and ADD + 66, ADD + 68 and ADD + 70, and ADD + 72 and ADD + 74, respectively, 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. With 5 and the set value 6, the winning probability of the bell is the same.

  Addresses ADD + 76, ADD + 78, ADD + 80, ADD + 82, ADD + 84, and ADD + 86 are each when the bet number is 3, that is, when the target lot of the internal lottery is a bell and the set value is 1 to 6 in the normal game state or small role game The address to be referenced. Since different values are registered in the addresses ADD + 76, ADD + 78, ADD + 80, ADD + 82, ADD + 84, and ADD + 86, the winning probability of the bell differs depending on the set value in the normal game state or the small role game.

  FIGS. 6A and 6B and FIGS. 7A to 7C 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. FIG. 6A shows a normal gaming state, FIG. 6B shows a 1 GCT, FIG. 7A shows a CTBB, and FIG. 7B shows a small role game. FIG. 7C shows an example when the player is in the regular bonus. FIGS. 6A, 6B, and 7A to 7C show examples in which the set value is 6, and the regular bonus winning flag, the big bonus winning flag, and the CTBB winning flag An example in which none is set is shown.

  For example, as shown in FIG. 6 (a), in the normal gaming state, the roles that are subject to the internal lottery are regular bonus (1), big bonus, CTBB, 1GCT, cherry, bell, bell B, and replay. In the setting value 6, the number of determination values is 20, 40, 40, 80, 269, 3582, 68, and 2245, respectively. First, the regular bonus (1), which is the subject of the internal lottery, is won when 16364-16383, which results in an overflow of the addition result by adding 20 judgment values, is acquired as a random number for internal lottery. It becomes.

  Next, for the big bonus that is the target of the internal lottery, the addition result overflows by adding 60, which is the sum of the determination value number 20 of the regular bonus (1) and the determination value number 40 of the big bonus. A win is made when ˜16363 is acquired as a random number for internal lottery. Similarly, when CTBB is acquired as a random number for internal lottery from 16284 to 16323, 1GCT is acquired as a random number for internal lottery from 16204 to 16283, and from 15935 to 16203 is an internal lottery when cherry is acquired Bell is replayed when 12353-15934 is acquired as a random number for internal lottery, and Bell B is replayed when 12285-12352 is acquired as a random number for internal lottery. Are determined as winning when 10040-12284 are acquired as random numbers for internal lottery.

  The approximate winning probabilities of the respective roles calculated based on the number of judgment values are 1 / 819.2 for each of the regular bonus (1), big bonus, CTBB, 1GCT, cherry, bell, bell B, and replay. 1 / 409.6, 1 / 409.6, 1 / 204.8, 1 / 60.9, 1 / 4.6, 1 / 240.9, and 1 / 7.3. When 0 to 10039 are acquired as random numbers for internal lottery, all combinations are lost.

  In addition, as shown in FIG. 6B, in 1 GCT, regular bonus (1), big bonus, CTBB, and replay are subject to internal lottery, and the numbers of judgment values are 1000, 3632, 3560, and 2245, respectively. Therefore, when 15384 to 16383, 11752 to 15383, 8192 to 11751, and 5947 to 8191 are acquired as random numbers for internal lottery, it is determined that the winning is made. In addition, the approximate winning probabilities of each combination are 1 / 16.4, 1 / 4.5, 1 / 4.6, 1 / 7.3. When 0 to 5946 are acquired as random numbers for internal lottery, all combinations are lost.

  Further, as shown in FIG. 7 (a), in CTBB, only the regular bonus (1) is the subject of internal lottery and the number of judgment values is 1000, so 15384 to 16383 are acquired as random numbers for internal lottery. Is determined to be a win. In addition, the approximate winning probability is 1 / 16.4. When 0-15383 is acquired as a random number for internal lottery, all combinations are lost.

  Further, as shown in FIG. 7B, in the small role game, the regular bonus (2), JACIN, cherry, bell, and bell B are subject to the internal lottery, and the respective number of judgment values is 21, 4311, 269. , 3582, 68, 16363 to 16383, 12052 to 16362, 11783 to 12051, 8201 to 11782, and 8133 to 8200 are acquired as internal random numbers, and are determined to be winning. In addition, the approximate winning probabilities for each combination are 1 / 780.2, 1 / 3.8, 1 / 60.9, 1 / 4.6, and 1 / 240.9. When 0 to 8132 are acquired as random numbers for internal lottery, all combinations are lost.

  Further, as shown in FIG. 7C, in the regular bonus, JAC, cherry, bell, and bell B are subject to internal lottery, and the number of determination values is 12363, 269, 3583, 68. When ˜16383, 3752-4020, 169-3751, 101-168 are acquired as random numbers for internal lottery, it is determined to be a winner. In addition, the approximate winning probabilities for each combination are 1 / 1.3, 1 / 60.9, 1 / 4.6, 1 / 240.9. When 0 to 100 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 acquired 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. It is assumed 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 bit to the 7th bit, and the upper counter 42c is a total of 16 bits from the 8th bit to the 15th bit. 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, the logic value of 1 may be read as L level, and the 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, every time 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. A 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 will be 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 sum operation is actually sequentially performed on the upper byte and the lower byte. By this OR operation, the 15th bit and the 7th bit are always 1. Further, 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. When any of the stop switches 8L, 8C, 8R is detected, the reel corresponding to the operated stop switch 8L, 8C, 8R is referred with reference to the table index and the reel control table stored in the ROM 41b. Control to stop the rotation of 2L, 2C, 2R is performed.

  In the table index, the table numbers of the reel control tables corresponding to the game state, the winning status of the combination, and the stop symbols of other reels are registered for each reel 2L, 2C, 2R. The reel control table also has a stop timing (a symbol number positioned at the reference position (the lower position of the fluoroscopic window 3 in this embodiment) when an operation of the stop switches 8L, 8C, and 8R is detected). The number of drawn-in symbols is registered.

  When any operation of the stop switches 8L, 8C, 8R is detected, the CPU 41a refers to the reel index, and corresponds to the gaming state at that time, the type of winning flag, and the stop status of other reels. The table number registered for the reel to be read is read, and the reel control table of the read table number is further referred to, and when the operation of the stop switches 8L, 8C, 8R is detected, the symbol positioned at the reference position The number of drawn symbols registered corresponding to the number is read out, rotated after the number of drawn symbols, and then controlled to stop the corresponding reel.

  In addition, as the number of drawn symbols in the reel control table, values of 0 to 4 are registered, and if the winning flag of the combination is won in the table index, in principle, the winning flag allows If the table number is registered so that the combination of the reel control table that draws the combination of the winning combination to the maximum is referred to, and the winning flag of any winning combination is not won, the reel that does not draw any winning combination Table numbers are registered so that combinations of control tables are referenced. For this reason, the rotation of the reels 2L, 2C, 2R is stopped within a drawing range within 4 symbols from when the stop switches 8L, 8C, 8R are operated. Then, if the symbols of the winning combination in the drawing range of 4 symbols can be aligned and stopped on the effective line set in each game, the control is performed to align and stop the winning combination. The symbol is controlled to be stopped in the drawing range of 4 symbols.

  Here, as shown in FIG. 2, “watermelon”, “bell”, and “JAC” are arranged at intervals of 5 symbols or less on each of the reels 2L, 2C, and 2R, and the drawing range of 4 symbols Thus, it is possible to stop at any position in the display area of the reels 2L, 2C, and 2R. In other words, when the winning flags of 1GCT, Bell, Bell B, Replay, JAC, and JACIN are set, in principle, the winning combination is always used regardless of the operation timing of the stop switches 8L, 8C, and 8R by the player. You can win a prize. However, as will be described later, this is not the case during CT.

  Next, the control of the CT game executed during 1GCT and CTBB, which is shifted by winning 1GCT and CTBB, will be described.

  When shifting to 1GCT or CTBB, the 1GCT in-progress flag or CTBB in-progress flag is set, and winning of cherry, bell, and bell B is permitted by these flags, so in CT games, it was permitted by internal lottery. In addition to the roles, winning of these roles is allowed.

  Also, in the CT game, for the left reel and the middle reel, as in other gaming states, the symbols of allowed roles (mainly bells and bells B in this embodiment) are drawn in a drawing range of up to four symbols. However, for the right reel, control is performed so that the symbol of the permitted role is drawn and stopped only within the drawing range of a maximum of one symbol. That is, the pull-in range is limited to one symbol only for the right reel.

  For this reason, in the CT game, if the symbol of the combination allowed in the drawing range of one symbol on the right reel can be stopped, it becomes possible to make a winning combination with the combination of the combination. In the present embodiment, as described above, the specified number of bets is 1 in 1 GCT and CTBB, and the number of payouts of Bell B is 15 as shown in FIG. 4B. In other words, when “Bell-Bell-BAR”, which is a combination of Bell B, is aligned on the effective line, the number of payouts is the largest, so that “BAR” can be stopped on the effective line of the right reel. It is preferable to perform a right reel stop operation.

  FIGS. 9A to 9J, FIGS. 10A to 10C, and FIGS. 11A to 11F are diagrams illustrating examples of the stop states of the reels 2L, 2C, and 2R in the CT game. . FIG. 12 is a diagram showing an example of a reel control table for the right reel referred to in the CT game.

  In this embodiment, as shown in FIG. 12, when the replay is not won during BBCT or 1GCT, the right reel is set to the first stop (hereinafter, the first stop is the first stop, the second is Is called the second stop, and the last stop is called the third stop), the reel control table of the table number R-CT1 is referred to. In the reel control table of the table number R-CT1, Since the 6th to 10th symbols are within the retractable range of “BAR”, as shown in FIGS. 9A and 9B, the stop operation is performed at the timing when any of the 6th to 10th symbols is located in the lower stage. In such a case, as shown in FIGS. 9C and 9D, “BAR” stops at the upper or lower stage of the right reel. When the stop operation of the left reel and the right reel is performed in this state, the control is performed so that the “bell” is pulled and stopped on the effective line where the “BAR” is stopped on the right reel. As shown in (f), the combination of bell B stops on the active line. In the reel control table of the table number R-CT1, since the “Bell” retractable range is other than the 6th to 10th symbols, for example, the stop operation is performed when any of the 6th to 10th symbols is positioned in the lower stage. Even if no is performed, as shown in FIGS. 9G and 9H, the “bell” stops at the upper or lower stage of the right reel. If the stop operation of the left reel and the right reel is performed in this state, the control is performed so that the “bell” is pulled and stopped on the effective line where the “bell” is stopped on the right reel. As shown in (j), the combination of bells stops on the active line.

  On the other hand, as shown in FIG. 12, when replay is not won during BBCT or 1GCT, when the right reel is set to the second stop or the third stop, it is stopped to the left reel or the middle reel. The reel control table with the table number R-CT2 or R-CT3 is referred to according to the design. For example, as shown in FIG. 10A, the left reel and the middle reel are stopped at either the winning line L2 or L4 among the active lines. At this time, the left reel and the middle reel are stopped at the left reel and the middle reel. The reel control table to be referred to differs depending on on which effective line the “bell” is stopped. When the “bell” of the left reel and the middle reel is stopped at the right slanting-down effective line, that is, when it stops at the winning line L4 (in this state, when “bell” or “BAR” stops at the lower position of the right reel) In this case, the reel control table of the table number R-CT2 is referred to, and when the “bell” of the left reel and the middle reel is stopped on the upper effective line, that is, the prize is won. When stopped at the line L5 (in this state, if "Bell" or "BAR" stops at the upper position of the right reel, a win is made, and this state is referred to as upper receiving), the reel of table number R-CT3 A control table is referenced. When the left reel is set to the first stop, the “bell” always stops at the upper stage. When the right reel is set to the second stop in this state, the middle reel is stopped. Even in the absence, the reel control table of the table number R-CT3 is referred to as the upper stage receiver. When the middle reel is set to the first stop, the “bell” is always stopped at the middle stage. When the right reel is set to the second stop in this state, the left reel is stopped. Even in the absence, the reel control table with the table number R-CT2 is referred to as the lower receiving.

  In the reel control table of table number R-CT2, the 8th to 10th symbols are within the retractable range of “BAR”, and the 1st, 2nd, 5th, 6th, 11th, 14th, 15th, 18th and 19th symbols are “bell”. 10 (b) (c), when the right reel is stopped at the timing when any of the 8th to 10th symbols is located in the lower stage in the lower stage receiving state, as shown in FIGS. The “BAR” stops at the lower stage of the right reel, and the right reel stops at the timing when any of the symbols 1, 2, 5, 6, 11, 14, 15, 18, 19 is located at the lower stage. If this is done, the “bell” stops at the bottom of the right reel, but if the right reel is stopped at a timing when the other symbols are positioned at the bottom, the “bell” or “BAR” The symbols other than It is not possible to win the bell B.

  In the reel control table of table number R-CT3, symbols 6 to 8 are “BAR” retractable ranges, and symbols 0, 3, 4, 9, 12, 13, 16, 17, and 20 are “bell”. In the upper receiving state, when the right reel is stopped at the timing when any of the 6th to 8th symbols is positioned in the lower stage, “BAR” is stopped in the upper stage of the right reel. If the right reel is stopped at the timing when any of the symbols 0, 3, 4, 9, 12, 13, 16, 17, 20 is located in the lower row, ”Stops, but if the right reel is stopped at the timing when the other symbols are positioned in the lower row, the symbols other than“ Bell ”or“ BAR ”are stopped in the upper row, and the bell or bell B is Cannot win a prize.

  As described above, when the replay is not won during BBCT or 1GCT, when the first reel other than the right reel is set as the first stop, the “bell” on the right reel is compared with the case where the right reel is set as the first stop. ”And“ BAR ”can be pulled in less. In other words, when the replay is not won during BBCT or 1GCT, the pullable range of the combination of combinations changes depending on whether the right reel is set to the first stop or the reel other than the right reel is set to the first stop. It is like that.

  Also, as shown in FIG. 12, when the right reel is set to the first stop when replay is won in 1 GCT, the reel control table of table number R-CT4 is referred to, and table number R- In the CT4 reel control table, since only the 9th symbol is within the pullable range of “BAR”, as shown in FIG. 11A, when the stop operation is performed at the timing when the 9th symbol is positioned in the lower stage. As shown in FIG. 11B, “BAR” stops at the lower stage of the right reel. When the stop operation of the left reel and the right reel is performed in this state, the control is performed so that the “bell” is pulled and stopped on the effective line where the “BAR” is stopped on the right reel. As shown, the combination of bells B stops on the active line. In the reel control table of table number R-CT4, since the range other than the 9th symbol is the “JAC” retractable range, even if the stop operation is not performed at the timing when the 9th symbol is positioned in the lower row, As shown in FIGS. 11 (c) and 11 (d), “JAC” stops at the upper or lower level of the right reel. When the stop operation of the left reel and the right reel is performed in this state, the control is performed so that “JAC” is drawn onto the effective line where “JAC” is stopped on the right reel and stopped. As shown in (f), the replay combination stops on the active line.

  On the other hand, as shown in FIG. 12, when the right reel is set to the second stop or the third stop when the replay is won in 1 GCT, the table corresponding to the symbols stopped on the left reel and the middle reel is used. The reel control table with the number R-CT5 or R-CT6 will be referred to. For the left and middle reels, “JAC” stops on either the winning line L3 or L5 of the active lines. At this time, “JAC” stopped on the left and middle reels stops on which active line Depending on whether or not, the reel control table to be referred to is different. When “JAC” of the left reel and the middle reel is stopped at the right-upward effective line, that is, when it stops at the winning line L5 and becomes the upper stage receiving, the reel control table of the table number R-CT5 is referred. When “JAC” of the left reel and the middle reel is stopped at the lower effective line, that is, when it is stopped at the winning line L3 and becomes the lower receiving, the reel control table of the table number R-CT6 is referred. . When the left reel is set to the first stop, “JAC” is always stopped at the lower stage. When the right reel is set to the second stop in this state, the middle reel is stopped. Even in the absence, the reel control table with the table number R-CT5 is referred to as the lower receiving. In addition, when the middle reel is set to the first stop, “JAC” always stops at the middle stage. When the right reel is set to the second stop in this state, the left reel is stopped. Even in the absence, the reel control table having the table number R-CT6 is referred to as the upper stage receiver.

  In the reel control table of table number R-CT5, the 8th to 10th symbols are within the pullable range of “BAR”, and the 0th, 3, 4, 7, 8, 12, 13, 16, 17, and 20 symbols are “ Because it is within the retractable range of “JAC”, the right reel stops at the timing when any of symbols 0, 3, 4, 7, 8, 12, 13, 16, 17, 20 is positioned in the lower stage in the lower stage receiving state. When the operation is performed, “JAC” stops at the lower stage of the right reel, but when the right reel is stopped at a timing when the other symbols are positioned at the lower stage, “JAC” is not displayed at the lower stage. This symbol stops and I cannot win a replay.

  In the reel control table of the table number R-CT6, the symbols 1, 2, 5, 6, 10, 11, 14, 15, 18, and 19 are within the retractable range of “JAC”. If the right reel is stopped at the timing at which one of the symbols 1, 2, 5, 6, 10, 11, 14, 15, 18, or 19 is located, “JAC” is displayed at the top of the right reel. However, if the right reel is stopped at a timing when symbols other than these are positioned in the lower stage, symbols other than “JAC” are stopped in the upper stage, and replay cannot be won.

  As described above, when the right reel is set to the first stop when the replay is won in 1 GCT, there is room for drawing the combination of the bell B into the effective line, although it is for one symbol. In the case where a combination other than the right reel is set to the first stop, the combination of the bell B cannot be drawn to the effective line, or the right reel is set to the first stop. In comparison, the retractable range of “JAC” in the right reel is also reduced. That is, even when a replay is won in 1 GCT, the pullable range of the combination of combinations changes depending on whether the right reel is set to the first stop or the reel other than the right reel is set to the first stop. Yes.

  In particular, in 1 GCT, the regular bonus (1), big bonus, and CTBB, which are special roles, are subject to internal lottery, and in the game during 1 GCT, the specified number of bets is 1 as described above. As shown in FIG. 6B, in the internal lottery, the number of determination values having a wider range than the number of determination values read out in the normal gaming state, that is, when the specified number of bets is 3, is read out. Since the regular bonus (1), big bonus, and CTBB will be determined based on the number of determination values, the regular bonus (1), big bonus, and CTBB have a higher probability than the normal gaming state in 1 GCT. Will be judged.

  Note that when a regular bonus (1), big bonus, or CTBB combination is won in a game during 1 GCT, the same control as when no replay is won in the game during 1 GCT is performed. That is, for the left reel and the middle reel, control is performed so that the “bell” is pulled in and stopped at a maximum of 4 symbols, and for the right reel, “BAR” and “bell” are only pulled at a maximum of 1 symbol. Control to pull in and stop is performed, and even if any of regular bonus (1), big bonus, or CTBB is won, control is performed so that the combination of these roles is not drawn on the active line. Is done. As described above, the regular bonus (1), the big bonus, and the CTBB winning flag are carried over to the next game when the combination of the combinations permitted by the flag is not completed. When the regular bonus (1), the big bonus, and the CTBB are won in this game, it is possible to align the winning combinations after the transition to the normal gaming state after the end of the 1GCT.

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

  FIG. 13 is a diagram illustrating an example of a command transmitted from the main control unit 41 to the effect control board 90.

  The BET command is a command that can specify the number of medals inserted, that is, the number of medals used to set the bet number. When a medal is inserted, the one-BET switch 5 or the MAX BET switch 6 is operated to set the bet number. Sent when

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

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

  The reel stop command is a command that can specify whether the reel to be stopped is the left reel, the middle reel, or the right reel, or the symbol to stop on the corresponding reel, and every time the reel is controlled to stop. Sent.

  The winning determination command is a command that can specify the presence / absence of winning, the type of winning, and the number of medals to be paid out at the time of winning, and is transmitted after all the reels are stopped and the winning determination is performed.

  The payout start command is a command for notifying the start of payout of medals, and is transmitted when the payout of medals by winning and winning a credit is started. The payout end command is a command for notifying the end of payout of medals, and is transmitted when the payout of medals by winning and winning a credit is completed.

  The gaming state command is a command that can specify the gaming state of the next game (whether it is a normal gaming state, 1 GCT, CTBB, small role game, regular bonus, etc.). Yes, sent at the end of the game.

  The standby command is a command indicating a transition to the standby state, and is transmitted when the transition to the standby state is made after a certain time has elapsed without setting the bet amount after the end of one game.

  The initialization command is a command indicating that the gaming state has been initialized, and is transmitted when the setting ends, that is, when the setting change mode ends.

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

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

  When the internal winning command is received, the effect pattern is selected at a selection rate corresponding to the result of the internal lottery indicated by the internal winning command, and is set in the RAM 91c. The selection rate of the effect pattern is registered in the effect table stored in the ROM 91b. When the CPU 91a receives the internal winning command, the CPU 91a is registered in the effect table according to the result of the internal lottery indicated by the internal winning command. The selected selection pattern is selected from a plurality of types of production patterns according to the selection rate, and the selected production pattern is set in the RAM 91c as the production pattern of the game.

  In addition, the CPU 91a executes a special 1GCT effect different from the effect executed in other game states, particularly in a 1GCT game. As shown in FIG. 14A, the 1GCT effect is composed of a 1GCT start effect indicating the start of 1GCT and a plurality of types of development patterns 1 to 5 that develop from the 1GCT start effect.

  In the 1GCT start effect, after receiving a gaming state command indicating that the next game is 1GCT, when a BET command is received for the first time, that is, in the 1GCT game, the first bet setting operation, that is, a medal is inserted. This is executed when the single BET switch 5 or the MAXBET switch is operated, and the development pattern is executed when the internal winning command is received thereafter, that is, when the game is started.

  When the CPU 91a receives a gaming state command indicating that the next game is 1GCT and then receives a BET command for the first time, the CPU 91a sets an effect pattern (hereinafter referred to as 1GCT start pattern) of the 1GCT start effect in the RAM 91c, The rendering device is controlled based on the 1GCT start pattern. After that, when an internal winning command is received, one of the development patterns 1 to 5 is selected according to the result of the internal lottery indicated by the internal winning command, and the selected development pattern is used as an effect pattern of the game. The effect device is controlled based on the developed pattern set in the RAM 91c.

  The selection rate of the developed pattern is registered in the 1GCT effect table stored in the ROM 91b. In the 1GCT production table, as shown in FIG. 14B, the selection rate of the development patterns 1 to 5 at the time of winning the regular bonus (1) is 20%, 25%, 35%, 10%, 10%, respectively. Are registered, and 15%, 20%, 20%, 30%, and 15% are registered as the selection rates of the development patterns 1 to 5 at the time of winning the big bonus, respectively, and the selection rates of the development patterns 1 to 5 at the time of winning the CTBB 15%, 20%, 20%, 15%, and 30% are registered, respectively, that is, as the selection rate of development patterns 1 to 5 at the time of replay winning or losing, 50%, 30%, 10%, 5% and 5% are registered.

  As described above, since different selection rates are determined in the 1GCT production table according to the result of the internal lottery, the development patterns 1 to 5 are executed with different probabilities according to the result of the internal lottery. . In particular, since the development patterns 3 to 5 are selected with a higher probability than the development patterns 1 and 2 when the special role is won, the development patterns 3 to 5 are executed more than when the development patterns 1 and 2 are executed. Sometimes you can expect to win a special role. Further, since the development pattern 3 is selected with a higher probability when the regular bonus (1) is won than when other special roles are won, the regular pattern (1) ) Can be expected. Further, since the development pattern 4 is selected with a higher probability when the big bonus is won than when other special roles are won, the big bonus can be expected especially when the development pattern 4 is executed. . Further, since the development pattern 5 is selected with a higher probability when winning the CTBB than when other special roles are won, the CTBB can be expected to win especially when the development pattern 5 is executed.

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

  When a 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, the adjustment data is stored so that the RAM parity becomes 0. Therefore, if the RAM parity is not 0 in the step of Sa7, the data stored in the RAM 41c is not normal. Therefore, 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, since the data in the RAM 41c is not normal, the routine proceeds to the RAM abnormality error processing shown in FIG.

  In the RAM abnormality error process, as shown in FIG. 16, 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, interruption is permitted (Sa15), and the setting change process shown in FIG. 20, 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. 17, the setting value stored in the setting value work of the RAM 41c (the value of the setting value work is corrected to 1 before shifting to the setting changing process. Is read out (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). Then, when it is determined in step Sb8 that the setting key switch 37 is OFF, the process returns to the flowchart of FIG. 15 and proceeds to the game process.

  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. 18 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.

  19 to 21 are flowcharts showing the control contents 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 (explained later, this is the stipulated number of bets determined according to the gaming state, and when it is in the regular bonus, 1GCT, CTBB, 1 is set, and it is in the normal gaming state and the small role game In some cases, a value of 3 is set, although only the normal gaming state is controlled by the replay game), and processing for determining whether or not the value of the BET counter is a specified number (Se3, Se4) is performed. It is repeatedly executed until it is determined that the value of the BET counter is a specified number in the Se4 step, and in the Se4 step, the BET counter There when it is determined that the prescribed number, it waits in the detection standby state of 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 insertion medal sensor 31 detects the passage of the insertion 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. 22 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. If the read set value is not a value in the range of 1 to 6, the process proceeds to the RAM abnormality error process shown in FIG.

  If the set value read in step Sf3 is in the range of 1 to 6, it is registered as an internal lottery object in the winning 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, CTBB, 1GCT or JACIN (Sf5). In the case of regular bonus, big bonus, CTBB, 1GCT or JACIN, the regular bonus winning flag, big bonus winning flag or CTBB winning flag is already set in the RAM 41c in the previous game, and the winning is based on the winning flag. It is determined whether it has been carried over without any change (Sf6). If the type of the read combination is not regular bonus, big bonus, CTBB, 1GCT, or JACIN, the process proceeds to Sf7.

  If the regular bonus winning flag, the big bonus winning flag or the CTBB winning flag is already set, the process returns to Sf4, and further, the next registered role in the winning state-specific winning table is read (regular bonus). Since the big bonus, CTBB, 1GCT, and JACIN are first registered in the winning combination table according to gaming state, this does not end the lottery process). Even if the type of the read combination is regular bonus, big bonus, CTBB, 1GCT, JACIN, if the regular bonus winning flag, big bonus winning flag, and CTBB winning flag are not 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 winning combination table according to gaming state being processed. 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 checked 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. As in the case where it is determined that the RAM data is not normal at the time of start-up, a RAM abnormality error state is set 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. 24 is a flowchart showing the control content of the reel stop process executed by the CPU 41a in step Sd4.

  In the reel stop process, first, it is determined whether or not an operation of the stop switch 8L is detected (Sh1). If the operation of the stop switch 8L is not detected, the process proceeds to the process of Sh4 as it is. If it is determined that the operation of the stop switch 8L is detected, the operation of the stop switch 8L is subsequently invalidated (Sh2). Next, a reel stop control process, which will be described later in detail, is performed with the left reel as the target reel (Sh3), and the process proceeds to Sh4.

  In step Sh4, it is determined whether an operation of the stop switch 8C is detected. If the operation of the stop switch 8C is not detected, the process proceeds to the process of Sh7 as it is. When it is determined that the operation of the stop switch 8C is detected, the operation of the stop switch 8C is invalidated thereafter (Sh5). Next, a reel stop control process is performed with the middle reel as the target reel (Sh6), and the process proceeds to Sh7.

  In step Sh7, it is determined whether an operation of the stop switch 8R is detected. If the operation of the stop switch 8R is not detected, the process proceeds to Sh10 as it is. When it is determined that the operation of the stop switch 8R is detected, the operation of the stop switch 8R is subsequently invalidated (Sh8). Next, a reel stop control process is performed with the right reel as the target reel (Sh9), and the process proceeds to Sh10.

  In step Sh10, it is determined whether all the left, middle, and right reels 2L, 2C, and 2R are stopped. When all the reels 2L, 2C, and 2R are stopped, the reel stop process is terminated and the process returns to the flowchart of FIG. On the other hand, if any one of the reels 2L, 2C, 2R is not stopped, the process returns to the process of Sh1, and the processes of Sh1 to Sh10 are repeated.

  Next, the reel stop control process for Sh3, Sh6, and Sh9 will be described in detail. FIG. 25 is a flowchart showing in detail the reel stop control process executed by the CPU 41a in Sh3, Sh6, and Sh9.

  In the reel stop control process, it is first determined whether or not it is the first stop (Si1). If it is the first stop, the table index stored in the ROM 41b is referred to, and a reel control table corresponding to the gaming state, the winning flag, and the target stop reel is selected (Si2). If the stop is not the first stop, the table index stored in the ROM 41b is referred to, and a reel control table corresponding to the game state, the winning flag, the target stop reel, and the stop symbol of the stopped reel is selected (Si3). ).

  Next, referring to the reel control table selected in the Si2 or Si3 step among the reel control tables stored in the ROM 41b, the symbol number located at the lower stage of the corresponding reel at the timing when the stop operation is performed corresponds to the symbol number. The registered number of drawn symbols is read and set in the RAM 41c (Si4).

  Next, the corresponding reel is stopped based on the number of drawn symbols set in the Si4 step. That is, after the reel rotates for the number of drawn symbols, the reel is stopped (Si5).

  FIG. 26 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 accordance with the current gaming state, the combination registered in the winning combination table according to gaming state in FIG. Are sequentially read (Sj1), and it is determined whether or not the combination of the read combinations is aligned on the effective 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 winning combination table by gaming state 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, it is determined whether or not the big bonus has been won by referring to the winning flag. If the big bonus has not been won, the process proceeds to Sj10. If the big bonus has been won, A big bonus medium flag indicating that it is present is set in the RAM 41c, and the big bonus winning flag is cleared (Sj8), and the value of the big bonus medium payout counter in which the total number of medals paid out in the big bonus is stored in the RAM 41c is initialized. (Sj9), the process proceeds to Sj10.

  In step Sj10, the winning flag is referenced to determine whether or not a regular bonus (including JACIN) has been won. If the regular bonus has not been won, the process proceeds to Sj13, and if the regular bonus has been won. The 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 (Sj11), and the number of regular bonus games is stored in the RAM 41c. After initializing the value of the regular bonus game number counter and the value of the regular bonus winning counter in which the number of winnings in the regular bonus is stored (Sj12), the process proceeds to Sj13.

  In step Sj13, it is determined whether or not CTBB has won a prize by referring to the winning flag. If CTBB has not won, the process proceeds to Sj16. If CTBB has won, it indicates that CTBB is in progress. The CTBB in-progress flag is set in the RAM 41c, the CTBB win flag is cleared (Sj14), and the value of the CTBB pay-out counter in which the total payout of medals in the CTBB is stored in the RAM 41c is initialized (Sj15). Proceed to the process.

  In step Sj16, it is determined whether or not 1GCT has won by referring to the winning flag. If 1GCT has not won, the winning determination process is terminated and the process returns to the flowchart of FIG. 18 to win 1GCT. If so, a 1GCT in-progress flag indicating that 1GCT is in progress is set in the RAM 41c (Sj17), the winning determination process is terminated, and the process returns to the flowchart of FIG.

  FIG. 27 is a flowchart 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 being performed, that is, whether a regular bonus, a big bonus, or a CTBB is being performed according to the current gaming state (Sk1). For example, the process proceeds to the process of Sk3, and if it is during a bonus, the values of various counters used during the bonus (the aforementioned big bonus medium payout counter, regular bonus game number counter, regular bonus medium payout counter, CTBB payout counter) Is updated (Sk2), and the process proceeds to Sk3.

  In the step of Sk3, it is determined whether or not the game is a replay game or 1GCT, and if it is not a replay game or 1GCT, the process proceeds to Sk5. If it is a replay game or 1GCT, the replay set in the RAM 41c is determined. The in-game flag or the 1GCT in-progress flag is cleared (Sk4), and the process proceeds to Sk5.

  In the step of Sk5, it is determined whether or not the game is in the big bonus. If it is in the big bonus, whether or not the big bonus end condition is satisfied, that is, the total number of payouts in the big bonus is 345. (Sk6), and if the big bonus is not in the step of Sk5 or if the big bonus end condition is not satisfied in the step of Sk6, the process proceeds to the process of Sk8, and the step of Sk6 If the big bonus end condition is satisfied, the big bonus medium flag set in the RAM 41c is cleared (Sk7), and the process proceeds to Sk8.

  In step Sk8, it is determined whether or not the game is in a regular bonus. If the game is in a regular bonus, whether or not the regular bonus end condition is satisfied, that is, the number of regular bonus games is 12 games. Whether the number of winnings in the regular bonus reaches 8 times, and if the regular bonus provided during the big bonus, the total number of payouts in the big bonus exceeds 345, (Sk9), if the regular bonus is not in the step of Sk8, or if the regular bonus end condition is not satisfied in the step of Sk9, the process proceeds to the process of Sk11, and the end condition of the regular bonus in the step of Sk9 Is established, the legi set in the RAM 41c Clear in color bonus flag (Sk10), the process proceeds to Sk11.

  In the step of Sk11, it is determined whether or not the game is in the CTBB. If the game is in the CTBB, whether or not the CTBB termination condition is satisfied, that is, the total number of payouts in the CTBB exceeds 253. Whether or not the regular bonus (1) has been won (Sk12). If the CTBB is not in the CTBB step, or if the CTBB termination condition is not satisfied in the Sk12 step, Proceeding to the process of Sk14, if the CTBB termination condition is satisfied in the step of Sk12, the CTBB in-process flag set in the RAM 41c is cleared (Sk13), and the process proceeds to Sk14.

  In step Sk14, it is determined whether or not the next game is in a regular bonus, CTBB or 1GCT gaming state. If the next game is in a regular bonus, CTBB or 1GCT gaming state, the RAM 41c is stored. The specified value of the set bet amount is 1 (Sk15), the winning flags other than the special combination set in the RAM 41c are cleared (Sk17), the process at the end of the game is terminated, and the flowchart shown in FIG. Return to. If the next game is not a regular bonus, CTBB, or 1GCT gaming state, that is, if the next game is a normal gaming state or a small role game in a big bonus, the specified value of the bet number set in the RAM 41c is set to 3. (Sk16), the winning flags other than the special combination set in the RAM 41c are cleared (Sk17), the process at the end of the game is terminated, and the process returns to the flowchart shown in FIG.

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

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

  In the startup process (sub), the built-in device, peripheral IC, interrupt mode, stack pointer, etc. are initialized (Sr1), and then access to the RAM 91c is permitted (Sr2). Then, the RAM parity of all the storage areas of the RAM 91c is calculated (Sr3), and it is determined whether or not the RAM parity is 0 (Sr4). If the data in the RAM 91c is normal, the RAM parity should be 0. If the RAM parity is 0 in the Sr4 step, the data stored in the RAM 91c is normal. (Sr5), interrupt is permitted (Sr7), and the process proceeds to loop processing. That is, it returns to the control state at the time of power interruption. If the RAM parity is not 0 in step Sr4, the data stored in the RAM 91c is not normal. Therefore, after the RAM 91c is initialized (Sr6), interrupts are permitted (Sr7) and the loop processing is performed. Transition.

  The CPU 91a executes a command reception interrupt process by interrupting other processes based on the detection of the strobe signal output from the game control board 40. The strobe signal is a signal input to the interrupt terminal of the sub-control unit 91 at the time of command transmission. In the command reception interrupt process, a process for acquiring command transmission line detection data from the input port, that is, a command output from the game control board 40, and storing it in a buffer provided in the RAM 91c is executed.

  FIG. 29 is a flowchart showing the control contents of the timer interrupt process (sub) executed by the CPU 91a at intervals of 1.12 ms based on the count of the internal clock.

  In the timer interrupt process (sub), first, it is determined whether or not a command is stored in the buffer (Sn1). If stored, the command is acquired from the buffer (Sn2), and it is determined whether the acquired command is an initialization command (Sn3). If the acquired command is an initialization command, the RAM 91c is initialized (Sn4), and then the process proceeds to Sn17.

  If it is determined in step Sn3 that the acquired command is not an initialization command, it is determined whether the acquired command is a gaming state command (Sn5). If the acquired command is not a gaming state command, the process proceeds to Sn. If the acquired command is a gaming state command, the gaming state indicated by the gaming state command is set in the RAM 91c (Sn6), and the process proceeds to Sn7.

  In the step of Sn7, it is determined whether or not the acquired command is a BET command. If it is not a BET command, the process proceeds to Sn10. If it is a BET command, the game is further based on the gaming state set in the RAM 91c. Is determined to be in 1 GCT (Sn8). If the game is not in 1GCT, the process proceeds to Sn14. If the game is in 1GCT, the 1GCT start pattern is set as an effect pattern in the RAM 91c (Sn9), and the process proceeds to Sn14.

  In the step of Sn10, it is determined whether or not the acquired command is an internal lottery command. If it is an internal lottery command, it is determined whether or not the game is in 1 GCT based on the gaming state set in the RAM 91c ( Sn11) If the game is in 1 GCT, the 1GCT production table stored in the ROM 91b is referred to, and the production pattern (development patterns 1 to 5) is selected according to the result of the internal lottery indicated by the internal lottery command. ) Is selected, the selected effect pattern is set in the RAM 91c as the effect pattern of the game (Sn12), and the process proceeds to Sn14. If the game is not in 1 GCT, an ordinary production table stored in the ROM 91b is referred to, the production pattern is selected at a selection rate according to the result of the internal lottery indicated by the internal lottery command, and the selected production pattern is selected. The effect pattern of the game is set in the RAM 91c (Sn13), and the process proceeds to Sn14.

  In the step of Sn14, the control pattern table stored in the ROM 91b is referred to, the control pattern registered in correspondence with the effect pattern set in the RAM 91c and the acquired command is read and set in the RAM 91c. A setting process is performed, and the process proceeds to the process of Sn15.

  In the step of Sn15, in accordance with the control pattern set in the step of Sn14, an effect control process for controlling various effect devices such as the liquid crystal display 51, the effect effect LED 52, the speakers 53 and 54, and the reel LED is executed. Proceed to step.

  In the step of Sn16, after updating the values of various counters such as the random number counter of the RAM 91c, the process proceeds to the processing of Sn17. In the step of Sn17, the content of data backed up in the RAM 91c at the time of activation is normal. Thus, the RAM parity adjustment data is calculated and set so that the exclusive OR of all the storage areas of the RAM 91c becomes 0, and the timer interrupt process (sub) is terminated.

  As described above, in the slot machine 1 of the present embodiment, in the CT game in which the combination of 1 GCT is aligned on the active line in the normal gaming state and only one game is controlled when a 1 GCT winning is generated, The regular bonus (1), big bonus, and CTBB winning are determined with a higher probability than in the normal gaming state. In other words, only 1GCT is provided in which only one game is provided in the normal gaming state. In the internal lottery, the regular bonus (1), the big bonus, the CTBB winning probability, that is, the regular bonus, big bonus, Since the probability of being controlled by the CTBB is higher than that in the normal gaming state, the player's expectation for the occurrence of regular bonuses, big bonuses, and CTBB in the CT game provided only in the normal gaming state is effectively increased. Can be increased.

  Also, in this embodiment, although the right reel pull-in is restricted as a specific game that is provided only in one game in the normal gaming state, a CT game that allows a small role winning regardless of the result of the internal lottery is applied. Since it is possible to win a small role by performing appropriate technical intervention, the interest in the specific game can be enhanced.

  In this embodiment, the CT game is applied as the specific game. For example, in a normal game state, when a combination of specific symbols is aligned with the active line, only one game has the same game state as the regular bonus described above. You may apply the required single bonus.

  In the present embodiment, the specified number of bets allowed to start a game in the normal gaming state is different from the specified number of bets allowed to start a game during 1 GCT. That is, in the normal gaming state, the start of the game is allowed only when the specified betting number of 3, which is the prescribed number of betting numbers corresponding to the normal gaming state, is allowed, and in the game in 1 GCT, the betting number corresponding to 1 GCT Since the start of the game is allowed only when the bet number of 1 which is the prescribed number of is set, the difference in the gaming state becomes clear due to the difference in the number of bets allowed to start the game, and the gameability is easy to understand It becomes.

  In addition, in the role-specific table, for regular bonus (1), big bonus, and CTBB determined as internal lottery targets in both the normal gaming state and 1 GCT, the storage destination address of the number of determination values for each bet number Is registered, and the number of determination values is acquired according to the number of bets. Here, the number of bets in 1 GCT is fixed at 1, but the number of bets in the normal gaming state is fixed at 3. As a result, the regular lottery (1), big bonus, and CTBB internal lottery can be performed with the winning probability corresponding to the gaming state only by acquiring the number of determination values according to the number of bets. Further, since it is not necessary to determine the gaming state when acquiring the determination value number, the processing steps in the internal lottery can be simplified.

  In addition, in a game during 1 GCT, for example, even if one of the regular bonus (1), big bonus, and CTBB is won, the combination of the regular bonus (1), big bonus, and CTBB is aligned on the active line. There is no control. For this reason, even if the regular bonus (1), big bonus, and CTBB are won in the game during 1 GCT, the winning regular bonus (1), big bonus, and CTBB cannot be generated in the game. Since these winnings are carried over after the next game, the expectation for winning the regular bonus (1), the big bonus, and the CTBB can be maintained even in the game after the end of 1GCT. Furthermore, even if these winning combinations are won, it is possible to arrange small roles, so that the CT game provided with only one game in the normal gaming state can be made more interesting.

  Further, in this embodiment, in the situation where 1 GCT is won and the game is shifted to 1 GCT, when the number of bets for starting the 1 GCT game is set, the 1 GCT start effect indicating that the game is 1 GCT. Is controlled, and the expectation that the winning probability of the regular bonus (1), the big bonus, and the CTBB will be increased by being controlled to 1 GCT. Furthermore, simultaneously with the start of the game by the operation of the start switch 7, that is, the internal lottery, the effect of any one of the development patterns 1 to 5 selected based on the selection rate according to the result of the internal lottery is executed Become. In other words, the development of the production at the timing when the internal lottery is executed, and the expectation for winning the regular bonus (1), big bonus, and CTBB can be effectively enhanced. With these effects, a CT game provided with only one game in the normal gaming state can be made more interesting.

  In this embodiment, when the minimum number of bets is set in a 1 GCT game, that is, when a medal is inserted or one BET switch 5 or MAX BET switch is operated (although the game starts in 1 GCT) Is set to 1 so that the 1GCT start effect is executed at the time when the number of bets allowed to start the 1GCT game is set). When the start of 1 GCT game is allowed by setting the bet number, the 1 GCT start effect may be executed when the bet number allowing start of the 1 GCT game is set.

  Also, in this embodiment, as a special gaming state advantageous to the player, a plurality of regular bonuses and regular bonuses that can obtain many medals without requiring much technical intervention, that is, not requiring much attention are provided. Big bonus and right-reel pull-in are limited, but winning of small roles is allowed, so CTBB, which can obtain many medals by applying some technical intervention, is applied. Since the game state is controlled to a special game state, it is possible to play a game with two game abilities and further enhance the interest.

  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 consume 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 game state and depends on the game 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 through winnings is the most basic role. It can be said. Here, there are JAC, cherry, bell, and bell B as types of small roles. In addition to JAC, which is awarded only in the regular bonus, it is determined as a type of winning combination in any gaming state. Yes. 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 wins JACIN with a transition to a regular bonus with a relatively high probability (winning because there is no missing). The big bonus is ended when the total number of medals paid out to the player in the big bonus reaches 345 regardless of the number of digest games. 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 as 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 JAC) 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, bell, and bell B that are also 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 gaming state from the small role game to the regular bonus in the big bonus is configured by a combination of “JAC-JAC-watermelon” and is not used as a display mode of other roles. It is. In the regular bonus, in addition to the small roles of Cherry, Bell, and Bell B, the JAC display mode that is determined to be a prize is also composed of a combination of “JAC-JAC-Bell” and is not used as a display mode for other roles. 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.

  The rotation of the reels 2L, 2C, and 2R is stopped by pulling in up to 4 symbols after the operation of the stop switches 8L, 8C, and 8R is detected except during 1GCT and CTBB. Can be selected from a range of 5 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, 1GCT constituted by these symbols, Bell, Replay, JAC, and JACIN won't miss out when they win. In particular, the JAC in the regular bonus will be won with a very high probability of approximately 1 / 1.3, but since this can not be missed, 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 to be paid out is registered according to the number of bets. When a winning of cherry, bell, or bell B occurs, the number of medals to be paid out is set according to the number of bets (although cherry As a result, the same number of medals is set for Bell.) Here, the number of bets in the regular bonus, CTBB, and 1GCT is fixed at 1, but the number of bets in the small role game and the normal gaming state 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 can be simplified. In addition, the number of bets 1 corresponding to the regular bonus, CTBB, and 1GCT has a larger number of medals at the time of winning the bell than the number of bets 3 so that the player's expectations for the regular bonus, CTBB, and 1GCT are further increased. It can be raised and the interest of the game can be improved.

  In the role-specific table, for each of the cherries, bells, and bells B that are defined as winning combinations in the normal gaming state, the small role game, and the regular bonus, the storage address of the judgment value number is registered for each bet number. Accordingly, the number of determination values is acquired according to the number of bets (although the same determination value number is acquired as a result in Cherry and Bell B). Here, the number of bets in the regular bonus is fixed at 1, but the number of bets in the normal gaming state and the small role game is fixed at 3. As a result, it is possible to perform an internal lottery of Cherry, Bell, and Bell B with a 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, since the bet number 1 corresponding to the regular bonus has a higher probability of winning the bell than when the bet number is 3, the player's expectation in the regular bonus is further enhanced, and the interest of the game is improved. Can do.

  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. Become.

  In addition, the storage address of the judgment value number of each combination registered in the combination table varies depending on the number of bets (1 or 3), but for example, at different addresses such as Cherry and Bell B. The number of stored judgment values may be the same.

  In the development model, it is normal to perform simulation while finely adjusting the judgment value data depending on 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 determination values adjusted by the simulation is the same regardless of the number of bets, the number of determination values is stored in the ROM 41b with the same address allocation as the address allocation 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. Become.

  In addition, the internal lottery adds the number of judgment values of each role referred from the role-specific table to the acquired random number for internal lottery, and depending on whether or not the result of the addition overflows, Judgment is made on whether or not there is a win. For this reason, an internal lottery can be performed using the number of determination values of each combination as it is. It should be noted that when the winning determination table is generated before the actual winning determination is made, the loop processing is required twice, but according to this embodiment, the loop processing in the lottery processing can 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 with the frequency of the pulse signal of the pulse generation circuit 42a. It will be lost.

  On the other hand, in the internal lottery, the number of determination values corresponding to each combination is sequentially added to the random value for the internal lottery. Therefore, 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 to update 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, the update of the random number generated by the random number generation circuit 42 becomes difficult to synchronize with the processing 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.

  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.

  In the above-described embodiment, the number of determination values referred to according to the number of bets for the same combination at the same set value is stored at a different address for each of the bets (1 or 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 good also as what performs.

  Further, in the above embodiment, the game can be started only by setting 3 as the bet number in the small role game in the normal gaming state and the big bonus. On the other hand, even in the small game in the normal gaming state and the big bonus, it is possible to start the game by setting 1 as the bet number, and further, by setting 2 as the bet number, You may be able to get started. As a result, when 1 or 2 is set as the bet number in the small game in the normal gaming state and the big bonus, the winning probability of the small role in the internal lottery is lower than when 3 is set as the bet number. In both cases, the number of medals to be paid out when winning a small role can be increased. For example, when 3 is set as the bet number in the small game in the normal gaming state and the big bonus, the winning probability of the bell is 1 / 4.6 and the payout number is 8, but the bet number is 1 or 2 Is set, the winning probability of the bell may be 1 / 240.9 and the payout number may be 15. Further, the winning probability of the bell and the number of payouts may be changed when 1 is set as the bet number and when 2 is set.

  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. 30 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. Further, 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. 31 is an explanatory diagram of a second 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 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. Further, 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 processing can be varied, and the effect of preventing the player from aiming can be achieved.

  In the embodiment, the slot machine for setting bets using medals and credits is used. However, the present invention is not limited to this, and the slot machine for setting bets using game balls.
