Description

  The present invention relates to a slot machine and a pachislot machine comprising: display means for variably displaying and stopping and displaying a plurality of symbols required for a game; and control means such as a microcomputer (hereinafter referred to as a microcomputer) for controlling the display means. The present invention relates to gaming machines, pachinko gaming machines, and other gaming machines.

  For example, pachislot machines that are currently mainstream have a plurality of types of winning modes. This winning mode is called a role. In particular, when a winning combination is won, the game state is better in condition than the normal state for a predetermined period of time, without finishing paying out a single medal. As such a combination, a combination that can play a game that gives a relatively large profit to a player a predetermined number of times (big bonus, hereinafter referred to as BB) and a game that gives a relatively small profit to the player There is a combination that can be performed a predetermined number of times (regular bonus, hereinafter referred to as RB). Hereinafter, BB and RB are collectively referred to as a bonus.

  Also, in the current mainstream models, a combination of predetermined symbols is arranged along a validated winning line of a plurality of reels where a plurality of symbols necessary for a game are arranged, and medals, coins, etc. are paid out In order to win a prize, a combination of symbols representing a winning combination of a winning combination (hereinafter referred to as a winning combination) is validated for a reel by an internal lottery process (hereinafter referred to as an internal lottery). The player is required to perform a stop operation at a timing at which the player can stop at the winning line. In other words, no matter how much you win, if the timing of the player's stop operation is bad, you cannot win the winning combination. That is, a gaming machine that requires a technique for performing a stop operation with good timing (having a high specific gravity of technology intervention) is currently the mainstream.

In addition, an effect display means such as a liquid crystal display device is provided, and some effect display is performed on the effect display means between the start and end of the variable display of the display means for displaying the symbols necessary for the game, which is performed by the display means. This eliminates the monotony until the game display becomes clear after the fluctuation display is stopped, and allows the player to concentrate on the game by performing an operation for stopping while watching the effect display. A gaming machine is provided (see, for example, Patent Document 1). Such a gaming machine is generally configured to notify the player of the establishment of a condition by displaying a specific effect when a predetermined condition such as a bonus is won is established. .

  However, in the gaming machine as described above, the effect image displayed on the effect display means is predetermined according to the winning combination, and the correspondence between the winning combination and the effect display is fixed. The pattern becomes universal and fixed. For this reason, the player cannot freely interpret the information implied by the display pattern of the effect display, and cannot freely estimate whether or not it is in an advantageous gaming state.

  In view of the above problems, the present invention allows the player to freely interpret information implied or suggested by the display pattern of the effect display, and can freely infer whether the game state is advantageous. An object is to provide a gaming machine.

  Specifically, the present invention provides the following.

  (1) A gaming machine that allows a unit game to be performed in accordance with a player's operation, and displays display means (for example, an effect display device 5 to be described later) that displays effects related to the game, and displays on the display means Display control means (for example, an image control circuit 72a, which will be described later) for controlling the effect display and at least one game information (for example, winning combination information) necessary for the progress of the game, with a predetermined probability (for example, The game information determination means (for example, the main control circuit 71 (see FIG. 13) for executing S16 of FIG. 16 described later) etc. determined based on the winning probability of each winning combination shown in the probability lottery table of FIG. ) And the total of the number of unit games (one game) used while the specific game information is determined by the game information determination means for the last predetermined number of times (for example, 3 times). Digestion Specific game information (for example, the main control circuit 71 that executes processing of S61 in FIG. 19 described later) and the game information determination unit that is statistically estimated based on the predetermined probability (for example, Distribution of the total occurrence probability (for example, normal distribution, etc.) of the number of digests of unit games performed while the specific game information is determined a predetermined number of times from the unit game for which the bonuses such as BB and RB are determined, And a probability distribution management means (for example, a ROM 83 (see FIG. 14) for storing the occurrence probability management table of the sum of the number of games between the three previous bonuses shown in FIG. 9) described later, and the display control means. Regardless of the at least one game information determined by the game information determining means, at least one effect state from a plurality of effect states is stored by the digest number storage means. Effect state selection means (for example, S63 in FIG. 19 to be described later) is selected based on the total number of digested unit games and the distribution of the total occurrence probability of the number of unit games managed by the probability distribution managing means. 19 for controlling the effect display based on the effect state selected by the effect state selection means (for example, the image control circuit 72a uses the effect state shown in FIG. 19 to be described later). A game machine characterized by, for example, determining an effect identifier by executing S65).

  According to the invention of (1), the effect display displayed on the display means is the sum and probability of the number of digests of the unit game stored by the continuation number storage means, regardless of the game information determined by the game information determination means. Since the effect display is controlled based on the effect state selected by the effect state selection means based on the distribution of the total occurrence probability of the number of unit games managed by the distribution management means, the display pattern of the effect display is Whether it is an advantageous gaming state by not only preventing the game from becoming less fun by universalizing and fixing, but also allowing the player to interpret the suggested and suggested information freely. It can be guessed freely and the interest of the game is improved.

  (2) In the gaming machine according to (1), the production states included in the plurality of production states are specific probabilities in which the occurrence probabilities managed by the probability distribution management unit are all derived from the predetermined probabilities. A gaming machine, which is either the above-described effect state or the effect state in which all the occurrence probabilities managed by the probability distribution management means are smaller than the specific probability.

  According to the invention of (2), the occurrence probability of the number of digests of the unit game that is performed until the specific game information is determined next from the unit game for which the specific game information is determined by the game information determination means, Since the performance state is defined based on the magnitude relationship with a specific probability derived from a predetermined probability, it becomes possible for the player to estimate the game advantage based on the statistical basis from the performance state. , The fun of gaming is improved.

  According to the present invention, not only can the display pattern of the effect display be universalized and fixed to prevent the game from becoming less interesting, but the display pattern of the effect display can be freely given to the player. Interpretation can be made to guess freely whether the game state is advantageous, and the interest of the game is improved.

Each reel 3L, 3C, 3R is rotationally driven so that the symbol row moves in the direction of the arrow in FIG.

  With reference to FIG. 3, the occurrence condition, the end condition, and the transfer destination game state of each game state of the gaming machine 1 will be described. The generation condition, end condition, and destination game state of each game state are as illustrated in FIG.

  There are four gaming states of the gaming machine 1; a general gaming state, a carryover state (including an RB carryover state during the BB gaming state), a BB general gaming state, and an RB gaming state. Here, the RB gaming state includes an RB gaming state during the BB gaming state and an RB gaming state during the general gaming state. In addition, a gaming state constituted by a predetermined combination of the BB general gaming state and the RB gaming state BB gaming state in the BB gaming state is referred to as a BB gaming state.

  The carryover state is a game state that transitions from the general game state or the BB game state, and is generated by winning a BB or RB, and is based on winning of the BB or RB, or the end of the BB game state or the start of the RB game state during the BB game state. finish. The carryover state is a state in which BB or RB is carried over, that is, a state in which information won in BB or RB is carried over. In particular, a state where BB is carried over is referred to as a BB carryover state, and a state where RB is carried over is referred to as an RB carryover state. In this carryover state, BB or RB winning is permitted unless a winning combination other than a loss is won.

  The BB general gaming state is a gaming state that shifts from the general gaming state, the BB carryover state, or the RB gaming state during the BB gaming state, and is generated when the BB is winning or when the BB gaming state ends, The game ends when the RB gaming state starts during the BB gaming state, or when the BB gaming state ends or the RB gaming state starts during the BB gaming state.

  The RB gaming state in the BB gaming state is generated when a specific condition is established in the BB gaming state or an RB winning in the BB gaming state, and a predetermined number (for example, 12 times) of the game ends, a predetermined number of times (for example, eight times). The game is ended by winning a small role or BB game state. Transition from the BB general gaming state to the RB gaming state, the RB gaming state is completed, the BB general gaming state is transitioned, and the transition to the RB gaming state is repeated until the number of paid-out medals reaches 466 or more. Is the BB gaming state.

  The RB gaming state in the general gaming state is generated by the RB winning in the general gaming state, and is caused by the predetermined number of times (for example, 12 times) the game end, the predetermined number of times (for example, eight times) the small role winning, or the end of the BB gaming state. finish.

  Note that the general gaming state is a gaming state that is not any of the carryover state, the BB general gaming state, or the RB gaming state.

  With reference to FIG. 4, a winning combination, a symbol combination, and a payout number will be described. The combination of the embodiment includes BB, RB, replay, watermelon small part, bell small part, and cherry small part. When this role is elected, it becomes a winning role, and when it wins further, it becomes a winning role. The winning mode of each combination (a combination of predetermined symbols along the active line) and the number of medals to be paid out at the time of winning vary depending on the number of BETs as shown in FIG.

  The winning of BB is realized by arranging red 7-red 7-red 7 or blue 7-blue 7-blue 7 along the active line in the general gaming state or the carryover state. After BB wins, the gaming state becomes the BB general gaming state. The BB gaming state is an advantageous gaming state compared to the RB gaming state.

  The RB winning is realized by arranging BAR-BAR-BAR along the active line in the general gaming state, the carryover state, or the BB general gaming state. The RB winning in the BB general gaming state may be referred to as JAC in. After the RB wins, the gaming state becomes the RB gaming state.

  The establishment of the replay is realized by arranging Replay-Replay-Replay along the active line in the general gaming state or the carryover state. When the replay is established, the same number of medals as the number of inserted medals are automatically inserted (the player is given game value), so that the player can play the next game without consuming the medals.

  In the general gaming state, the carryover state, the BB general gaming state, and the RB gaming state, it is possible to realize a winning combination of a watermelon small part, a bell small part, and a cherry small part, As shown, it depends on the number of BETs. There are medium cherry and small cherry small roles. The winning of the small portion of the corner cherry is realized by the cherry being stopped and displayed on the upper or lower portion of the left display window 4L. Further, the winning of the small cherry role is realized by stopping and displaying the cherry in the middle of the left display window 4L.

  With reference to FIG. 5, the probability lottery table referred to in the probability lottery process of step (hereinafter referred to as S) 16 of FIG. The probability lottery table is provided for each of five gaming states, that is, a general gaming state, a carryover state, a BB general gaming state, an RB gaming state in the BB gaming state, and an RB gaming state in the general gaming state. The data table is stored in a ROM 32 (see FIG. 13) described later.

  The random number extraction range of this probability lottery table is 0 to 16383, and one random number is extracted from this random number extraction range in S13 of FIG. 16 to be described later, and this random number is the random number range of any winning combination depending on the gaming state. The winning combination is determined depending on whether it belongs to. For example, when the extracted random number is 15 in the general gaming state, since the random number belongs to the random number range of BB, the winning combination is BB. The probability that this BB is determined as a winning combination is 47/16384, which is obtained by dividing 47 random numbers belonging to the random number range from 0 to 46 by the number 16384 of numerical values belonging to the random number extraction range. The process of determining the winning combination in the case of other gaming states and / or in the case of other winning combinations, and the winning probabilities thereof are also the same.

  With reference to FIG. 6, the winning combination determination table for stop referred to in the winning combination determination process for stop of S17 of FIG. 16 mentioned later is demonstrated. The winning combination determination table for stop is provided for each of the above five gaming states, and is stored in a ROM 32 (see FIG. 13) described later as a predetermined data table.

  The random number extraction range of this stop winning combination determination table is from 0 to 127. One random number is extracted from this random number extraction range, and this random number belongs to the random number range of any stop winning combination according to the winning combination. Depending on how, the winning combination for stoppage is determined. For example, when the game state is a general gaming state and the winning combination is a cherry small combination, and the extracted random number is 9, this random number belongs to the random number range of the small winning combination for the middle cherry. The winning role will be a small role for Medium Cherry. The probability that the small cherry part is determined to be a winning winning combination is 16/128, which is 16 which is the number of random numbers belonging to the random number range from 0 to 15 divided by the number 128 of numerical values belonging to the random number extraction range. is there. The process for determining the winning combination for stopping in the case of other gaming states and / or in the case of other winning combinations for stopping, and the determination probabilities thereof are also the same.

  In addition, when the winning role is a cherry small role, it does not determine the winning role for stopping the medium cherry small size and the corner cherry small role, but by the stop control, the medium cherry small size and the corner cherry small role You may make it distribute.

  Next, with reference to FIG. 7, the stop table group selected corresponding to the gaming state and the winning combination for stop will be described. The stop table group is a set of stop tables used for stop control of the reels 3L, 3C, and 3R in the process of S26 in FIG. The stop table will be described with reference to FIG.

The RB winning stop table group is a set of RB winning stop tables, and the RB winning stop table is a stop table that allows RB winning according to the player's stop operation. The replay establishment possible stop table group is a set of replay establishment possible stop tables, and the replay establishment possible stop table is a stop table in which establishment of a replay is permitted regardless of a player's stop operation. The watermelon small role winning stop table group is a set of watermelon small role possible stop tables, and the watermelon small role possible stop table is allowed to win a watermelon small role according to a player's stop operation. It is a stop table. The bell small role winning stop table group is a set of bell small role possible stop tables, and the bell small role possible stop table allows the bell small role winning regardless of the player's stop operation. It is a stop table. The medium cherry small role winning stop table group is a set of medium cherry small role possible stop tables, and the medium cherry small role possible stop table is a prize for the medium cherry small role according to the player's stop operation. Is an allowable stop table. The corner cherry small role winning stop table group is a set of corner cherry small role possible stop tables, and the corner cherry small role possible stop table is a winning combination of corner cherry small roles according to the player's stop operation. Is an allowable stop table. The non-winning stop table group is a set of non-winning stop tables, and the non-winning stop table is a stop table that does not allow any winning combination regardless of the player's stop operation.

  Next, with reference to FIG. 8, a stop table stored in a ROM 32 (see FIG. 14) of the main control circuit 71 described later will be described.

  The stop table shows stop operation positions and stop control positions of the reels 3L, 3C, and 3R. The stop operation position is a symbol that is located on the center line 8c when the stop buttons 7L, 7C, and 7R provided corresponding to the reels 3L, 3C, and 3R are operated (specifically, The code number of a symbol whose center is located above the center line 8c and whose center is closest to the position of the center line 8c). The stop control position represents a code number of a symbol that is stopped and displayed at the position of the center line 8c when the reel on which the stop operation is performed stops. Here, in the present embodiment, the maximum number of sliding frames is four. Referring to FIG. 8A, for example, when the stop button 7R is operated when the bell (symbol 92) of the code number 14 reaches the position of the center line 8c during the rotation of the right reel 3R, The right reel 3R can be controlled to stop so that the number 16 cherry (symbol 95) is stopped and displayed at the position of the center line 8c.

  The stop table includes a BB winning stop table included in the BB winning stop table group, an RB winning stop table included in the RB winning stop table group, a replay enable stop table included in the replay enable stop table group, The watermelon small role winning stop table included in the watermelon small role winning stop table group, the bell small role winning stop table included in the bell small role winning stop table group, the medium cherry small role winning stop Stopper table included in the table cherries included in the small cherries included in the table group, Stopper table included in the cherries included in the small cherries included in the small cherries of the horned cherry There is a stop table.

  The replay establishment possible stop table (not shown) is used when the reels 3L, 3C, and 3R are controlled to stop so that the replay is established when the winning combination for stop is replay. In the replay establishment possible stop table, in each reel 3L, 3C, 3R, replay can be established only when a stop operation is performed at a predetermined stop operation position, and stop operation positions other than the predetermined stop operation position. If a stop operation is performed in step 1, replay cannot be established.

  FIG. 8A shows an example of a bell small role winning possible stop table included in the bell small role winning possible stop table group shown in FIG. This table is used when the reels 3L, 3C, and 3R are controlled to stop so that the bell wins when the winning winning combination is a bell.

  In FIG. 8A, the stop control position of the left reel 3L is any one of code numbers 04, 08, 13, 16, and 20. In the symbol arrangement shown in FIG. 2, all symbols corresponding to positions one code number 04, 08, 13, 16, 20 are bells (symbol 92).

  In FIG. 8A, the stop control position of the central reel 3C is any one of the code numbers 01, 06, 09, 13, and 18. In the symbol array shown in FIG. 2, all symbols corresponding to code numbers 01, 06, 09, 13, and 18 are bells (symbol 92).

  Further, in FIG. 8A, the stop control position of the right reel 3R is any one of code numbers 03, 08, 12, 16, and 20. In the symbol arrangement shown in FIG. 2, all symbols corresponding to the positions one code number 03, 08, 12, 16, and 20 are bells (symbol 92).

  As described above, when the bell small role winning stop table shown in FIG. 8A is used for the stop control of the reels 3L, 3C, 3R, the cross-down line 8e is activated. , Bell-bell-bells are displayed side by side and the bell can be won.

  When the bell small role winning stop table is used for stop control of each reel 3L, 3C, 3R, three bells (symbol 92) are stopped and displayed along the cross-down line 8e. It is always possible to win a small role. In this embodiment, when a bell small role is won, a winning can always be established. This is related to the arrangement of the bell (symbol 92) in the symbol array shown in FIG. In this embodiment, the maximum number of so-called sliding frames is four, and if there is a symbol that establishes a winning in the range of four frames from the position where the stop operation is performed, it is possible to draw on the active line. Referring to FIG. 2, in each of the reels 3L, 3C, and 3R, the bell (symbol 92) has a symbol arrangement that is always arranged in the range of four frames. For this reason, the bell (symbol 92) can be arranged on the effective line regardless of the position at which the stop operation is performed on each reel 3L, 3C, 3R. In other words, basically, the small part of the bell does not cause a so-called missing (inability to establish a winning combination for the selected winning combination for stoppage).

  The watermelon small role winning stop table (not shown) is used when the reels 3L, 3C, and 3R are controlled to stop so that the watermelon small role is won when the winning winning combination is a watermelon small role. used. In the watermelon small role winning possible stop table, each of the reels 3L, 3C, 3R can receive a watermelon small role only when a stop operation is performed at a predetermined stop operation position. When a stop operation is performed at a stop operation position other than the position, the small part of the watermelon cannot be won.

  The medium cherry small combination winning stop table (not shown) is used when the left reel 3L is controlled to stop when the winning combination for stopping is a medium cherry small combination. In the middle cherry small role winning stop table, the middle cherry small role can be won only when the stop operation is performed at the predetermined stop operation position on the left reel 3L, except for the predetermined stop operation position. When the stop operation is performed at the stop operation position, the small cherry small role cannot be won.

  A corner cherry small role winning stop table (not shown) is used to stop and control the left reel 3L so that the corner cherry small role wins when the winning winning combination is a corner cherry small role. Is done. In the corner cherry small role winning stop table, the corner cherry small role can be won only when the stop operation is performed at the predetermined stop operation position on the left reel 3L, and other than the predetermined stop operation position. When the stop operation is performed at the stop operation position, it is not possible to win the small portion of the corner cherry.

  In the present embodiment, even when a replay, watermelon small part, medium cherry small part, or corner cherry small part is selected as a winning combination for stopping, and a winning (established) possible stop table is selected, There are cases where winning (establishment) is not possible. This is related to the arrangement of replay (symbol 94), cherry (symbol 95), or watermelon (symbol 96) in the symbol array shown in FIG. Referring to FIG. 2, in the left reel 3L, cherries (symbol 95) are not arranged in a pattern arrangement that is necessarily arranged in the range of four frames, but are arranged only at the positions of code numbers 02 and 11. For this reason, the cherry (symbol 95) cannot be stopped at the effective line depending on the stop operation position. That is, the small cherry role and the small cherry role are so-called missed roles. Similarly, referring to FIG. 2, in each of the reels 3L, 3C, and 3R, the replay (symbol 94) and the watermelon (symbol 96) are arranged so that they are always arranged in the range of 4 frames. Absent. For this reason, depending on the stop operation position, the replay (symbol 94) and the watermelon (symbol 96) cannot be stopped at the effective line. That is, the replay and the watermelon small role are roles in which so-called missing may occur.

  In the present embodiment, the winning combination for stopping that may be missed has been described as an example of a replay, a small cherry small role, a corner cherry small role, or a watermelon small role, but BB (blue 7 (design) 91)), red 7 (symbol 97), and RB (BAR (symbol 93)) are also winning winning combinations that can be missed. That is, blue 7 (symbol 91), red 7 (symbol 97) or BAR (symbol 93) are all arranged in a pattern arrangement in which the reels 3L, 3C and 3R are necessarily arranged in the range of 4 frames. Not. For this reason, depending on the stop operation position, blue 7 (symbol 91), red 7 (symbol 97), and BAR (symbol 93) may not be stopped at the active line.

  FIG. 8 (2) shows an example of a non-winning stop table included in the non-winning stop table group shown in FIG. This table is used when the reels 3L, 3C, and 3R are controlled to stop so that no winning combination is won when the winning combination for stopping is lost.

  In FIG. 8 (2), the stop control position of the left reel 3L is any one of the code numbers 00, 05, 09, 14, and 17. In the symbol array shown in FIG. 2, the symbols corresponding to the position one code number 00, 05, 09, 14, 17 are not all Replay (symbol 94).

  In FIG. 8B, the stop control position of the central reel 3C is any one of the code numbers 02, 05, 10, 14, and 19. In the symbol array shown in FIG. 2, all symbols corresponding to code numbers 02, 05, 10, 14, and 19 are Replay (symbol 94).

  Further, in FIG. 8B, the stop control position of the right reel 3R is any one of code numbers 03, 08, 12, 16, and 20. In the symbol arrangement shown in FIG. 2, all symbols corresponding to the positions one code number 03, 08, 12, 16, and 20 are bells (symbol 92).

  As described above, when the non-winning stop table shown in FIG. 8 (2) is used for stop control of the reels 3L, 3C, and 3R, along the activated cross-down line 8e, The symbols are not stopped and displayed side by side, and any combination cannot be won.

  Next, with reference to FIG. 9, a description will be given of the occurrence probability management table for the sum of the previous three bonus-time games, which is referred to in the processing of S62 in FIG. This table is stored in a later-described ROM 83 (see FIG. 14) as a predetermined data table. The occurrence probability of the sum of the number of games between the previous three bonuses is the sum of the number of games (number of unit games) spent until the last (most recent) three bonuses (BB or RB) are won, The probability of being a certain number. By referring to this table in the process of S62 of FIG. 19, it is possible to search for the occurrence probabilities with respect to the sum of the previous three bonus games x = 3, 4,. The term “between bonuses” refers to the period from the end of a bonus (BB or RB) to the occurrence of the next bonus (BB or RB). Therefore, the sum of the number of games between the three previous bonuses means the number of games consumed from the end of the bonus to the next occurrence of the bonus. In other words, the sum of the number of games between the three previous bonuses is the number of games as the cost required to win one bonus. Further, the occurrence probability of the sum of the number of games between the three previous bonuses means the probability that the number of games digested from the end of the bonus to the next bonus occurrence will be a certain number of games. Therefore, the occurrence probability management table for the sum of the previous three bonus games is a table for managing the occurrence probability for each of the previous three bonus games.

  By the way, the probability that the sum of the three previous bonus games will be a certain number of games is statistically estimated as follows. For example, it is statistically known that when the statistics of the frequency distribution of the height of Japanese men are taken, the distribution generally follows a normal distribution. Similarly, in a pachislot machine, regarding the sufficiently large natural number n, when taking the frequency distribution of the sum of the number of games between the three bonuses that occur before n games, this distribution is generally normal. It is expected to follow the distribution. Therefore, regarding the sufficiently large number n, the occurrence probability of the sum of the number of games between bonuses three times before occurring during n games is also expected to follow a normal distribution. Based on such statistical experience, the distribution of occurrence probabilities of the sum of the number of games between the previous three bonuses can follow a normal distribution.

  In the gaming machine 1 of the present embodiment, the average (expected value) of the distribution of the occurrence probability of the sum of the previous three bonus games is considered as follows. That is, in the probability lottery table in FIG. 5A, the probabilities of winning BB and RB are 47/16384 and 20/16384, respectively. Therefore, in the gaming machine 1 of the present embodiment, the probability that BB or RB is won is (47/16384) + (20/16384) = 67/16384 (≈0.004089, hereinafter, this number is the bonus winning probability ). From this, it can be said that the gaming machine 1 of the present embodiment wins BB or RB 67 times out of 16384 games. From now on, if the bonus is won on average, 16384/67 = 244.5373, which is the reciprocal of 67/16384, can be said to be the average of the distribution of the occurrence probability of the sum of the number of games between bonuses. That is, on average, BB or RB wins once in 244.5373 games. The average distribution of the occurrence probability of the sum of the three bonus games is 244.5373 × 3 = 733.6119, which is three times the average number of games per bonus winning. Hereinafter, 733.6119 is the average (expected value) of the number of games between the previous three bonuses.

  From the above considerations, the distribution of the probability of the sum of the three previous bonus games is a normal distribution with 733.6119 games as an average (expected value), so the sum of the previous three bonus games is x. When the variance is σ, the occurrence probability P (x) of the sum of the previous three bonus game numbers at this time can be expressed by the following equation.

  Note that the initial value of x is 3, since x is the sum of the previous three bonus games and is at least 3.

  Here, the variance σ is unknown, but this σ is obtained as follows. That is, the total probability of the probability expressed by P (x), that is, the sum of P (x) from x = 3 to x = ∞ is 1.

  When σ is obtained by numerical calculation, assuming that the intermediate formula = 1 of the above (2) is an equation relating to σ, σ = 42.5. However, strictly speaking, in consideration of errors due to numerical calculation, it is considered that a value in the range of 41 to 44 and a value in the vicinity of this range are appropriate for σ. In this embodiment, σ = 42.5 is obtained by averaging the above numerical value ranges. The value of σ is a numerical value that can be regarded as a solution of the above equation in consideration of errors in numerical calculation.

  Therefore, it can be concluded that the occurrence probability P (x) of the sum of the number of games between the three previous bonuses is as follows.

  When the value of the occurrence probability P (x) corresponding to x = 3, 3,... Is obtained from the expression (3), the occurrence probability of the sum of the previous three bonus-to-bonus games shown in FIG. I want.

  Referring to FIG. 9, it can be seen that P (x) = 0 can be considered numerically after the sum of the number of games between the previous three bonus games is 2329 or later. Therefore, in the row of the occurrence probability management table of the sum of the number of games between the previous three bonuses shown in FIG. 9, the row where the sum of the number of games between the previous three bonuses is larger than 2329 can be omitted as appropriate. In addition, in consideration of the recording capacity of the ROM 83 (see FIG. 14), it is omitted as appropriate.

  In addition, when the correspondence between the sum of the three previous bonus games shown in FIG. 9 and the occurrence probability is graphed, a normal distribution is obtained as shown in FIG. 26 described later. The distribution of the occurrence probability of the sum of the number of games between the previous three bonuses represents the correspondence of P (x) to the discrete value x, and does not represent the correspondence to the continuous value. Not a normal distribution. The curve in the graph of FIG. 26 is a set of points in which the value of P (x) is plotted with respect to the discrete value x, not continuous as in the normal distribution curve. However, since it represents a distribution that is almost equal to the normal distribution, in this embodiment, even if the distribution of the occurrence probability of the sum of the number of games between the previous three bonuses is regarded as a normal distribution, there is a special inconvenience in handling. Absent.

  Next, with reference to FIG. 10, an effect state determination table referred to by a later-described sub control circuit microcomputer 81 (see FIG. 14) in S63 of the start command receiving process of FIG. 19 described later will be described. This table is stored in a later-described ROM 83 (see FIG. 14) as a predetermined data table.

  The effect state means an effect display stage displayed on the display screen 5 a of the liquid crystal display device 5. The stage in the effect display is specified by the effect state, and the movement of the main character m in the effect display and the state of the stage are specified by the effect identifier described later. In this way, the effect display is specified by the combination of the effect state and the effect identifier. When the production state is 1, the stage of production display is the sea as shown in FIG. 23 (1), and when the production state is 2, the stage of production display is the mountain as shown in FIG. When the production state is 3, the stage of production display is a field as shown in FIG. For example, when the stage is at the sea, the main character m takes a predetermined movement based on the production identifier with the sea as the stage, and the situation such as the weather on the stage is specified.

  This effect state determination table includes the value of a counter that stores the sum of the three previous bonus games stored in the work RAM 84 (see FIG. 14) and the sum of the previous three bonus games in FIG. The production state is determined depending on whether or not the occurrence probability of the sum of the number of games between bonuses three times searched from the occurrence probability management table satisfies a predetermined condition. Therefore, a numerical value is added to the counter that stores the sum of the previous three bonus game numbers, and the production state is changed in accordance with the occurrence probability of the previous three bonus game numbers corresponding to this numerical value. Is selected.

For example, when the value of the counter for storing the sum of the three previous bonus games is 500, the occurrence probability of the sum of the previous three bonus games corresponding to this value is 2.5979 × 10 ⁻⁹ . The sum of the three previous bonus games counted by the counting means is smaller than the expected sum of the previous three bonus games (500 <733.6119) and the sum of the previous three bonus games Since the condition that the occurrence probability is smaller than the theoretical value of the average occurrence probability of the number of games between the three bonuses before (2.5797 × 10 ⁻⁹ <0.000000003426) is satisfied, the production state is 1, that is, the sea stage. In addition, the theoretical value of the average occurrence probability of the number of games between the three previous bonuses is obtained as follows. In other words, three of the 733.6119 games are won by the bonus, and the remaining (733.6119-3) games are non-bonus, so (bonus winning probability) ³ × (bonus non-winning probability) ^(733.6119-3) = (67 / 16384) ³ × ((16384-67) / 16384) ^(733.6119-3) = about 0.000000003426. The process of determining other performance states and the determination probabilities are the same. Note that there are six settings for setting the winning probability of each winning combination of the gaming machine 1 (usually, setting 1, setting 2, setting 3, setting 4, setting 5, setting 6). The bonus winning probability is different every time (the winning probability of the role is high), and the theoretical value of the average occurrence probability of the sum of the expected number of games between the previous three bonuses and the sum of the number of games between the previous three bonuses is It may be different.

  Next, with reference to FIG. 11, an effect pattern selection table referred to by a sub control circuit microcomputer 81 (see FIG. 14) described later in S65 of the start command receiving process of FIG. 19 described later will be described. This table is stored in a later-described ROM 83 (see FIG. 14) as a predetermined data table.

  The effect pattern is a situation such as the movement of the main character m in the effect display and the weather of the stage specified by the effect identifier. This production pattern is common to any production state 1 to production state 3, and there are production pattern 01 to production pattern 10. For example, as shown in FIG. 24 (1), the stage of the effect display is the sea, and in the effect pattern 01, the main character m moves the display screen 5a from the left to the right, and the state of the stage is the display screen 5a. A cloud c appears on the screen. Similarly, in the production patterns 02, 03, 04, 05, 06, 07, the main character m moves the display screen 5a from the left to the right, and the state of the stage is that the clouds c are 2, 3 and 3 on the display screen 5a. 4, 5, 6, and 7 appear (see FIGS. 24 (2) to (7)).

  Then, as shown in FIG. 25 (8), in the effect pattern 08, the main character m moves the display screen 5a from the left to the right, and the state of the stage is that the cloud c disappears from the display screen 5a and the sun s Appears. As shown in FIG. 25 (9), in the production pattern 09, the main character m moves the display screen 5a from the left to the right, and the stage situation is that the cloud c disappears from the display screen 5a, and the thundercloud and lightning t Appears. Further, as shown in FIG. 25 (10), in the effect pattern 10, the main character m moves the display screen 5a from the left to the right, and in the stage state, the cloud c disappears from the display screen 5a, and the rain cloud r Appears. These effect patterns specified by the effect identifiers of the effect pattern 08 to the effect pattern 10 specify a more impressive effect display compared to the effect patterns specified by the effect identifiers other than these, and are therefore collectively referred to as development effects. .

  Even when the stage of the effect display is mountain or field, if the effect identifier is the same, the movement of the main character m on the display screen 5a and the number of clouds c appearing on the display screen 5a or the sun s, thunderclouds The appearance mode of either lightning bolt t or rain cloud r is the same.

  The random number extraction range of this effect pattern selection table is 0 to 127, one random number is extracted from this random number extraction range, and the effect state previously determined in S62 of the start command reception process of FIG. An effect pattern is determined depending on which effect state the random number belongs to. The effect pattern is specified by the effect state and the effect identifier. For example, when the production state is 1 and the extracted random number is 9, since this random number belongs to the random number range of the production identifier 01 with the production state 1, the production pattern is the production identifier 01 with the production state 1; This is the stage identifier 01 for the sea stage. When the production state is 1, the probability that this production pattern 01 is determined as the production state is obtained by dividing 17 which is the number of random numbers belonging to the random number range from 0 to 16 by the number 128 of numerical values belonging to the random number extraction range. 17/128. The process of selecting other effect patterns and the selection probabilities in the case of other effect states are the same.

  Referring to FIG. 11, the effect identifiers that can be selected in effect state 1 to effect state 3 are effect pattern 01 to effect pattern 10. That is, even if the production state is different, if the production identifier is the same, only the stage of the production display is different, and the situation such as the movement of the main character m in each stage and the weather of the stage are the same. However, the probability that each production identifier is selected differs depending on each stage as shown in the figure.

  What should be noted here is the selection probability of the development effect. On the sea stage (production state 1), the production pattern 08 is selected with a probability of 12/128, and the production pattern 09 and the production pattern 10 are selected with a probability of 4/128. On the other hand, in the mountain stage (production state 2), the production pattern 09 is selected with a probability of 12/128, and the production pattern 08 and the production pattern 10 are selected with a probability of 4/128. In state 3), the effect pattern 10 is selected with a probability of 12/128, and the effect pattern 08 and the effect pattern 09 are selected with a probability of 4/128. In this way, each stage can be characterized by changing the production identifier of the development effect selected with high probability in each stage. When each stage is characterized in this way, the player can freely interpret the information suggested and implied by the effect display, and can freely interpret whether the game is in an advantageous state, thereby improving the interest of the game. There is a case.

  Next, referring to FIG. 12, a table (hereinafter referred to as an image data storage address table) showing the correspondence between the combination of the effect state and the effect identifier, the effect data storage address and the next frame address will be described. This table is stored in a later-described ROM 83 (see FIG. 14) as a predetermined data table.

For example, the effect display whose effect identifier is the effect pattern 01 when the effect state is 1 is composed of frames (two-dimensional images) from frame 01 to frame n11 ₁ and these frames are sequentially switched and displayed. To compose a video. That is, a frame refers to one still image and one screen constituting a moving image.

  The effect display of the present embodiment is 2D graphics that composes a moving image by sequentially switching and displaying 2D (Two Dimension) images. However, the present invention is not limited to this, and it may be 3D graphics that digitizes a 3D (Three Dimension) image and displays a three-dimensional moving image by changing the numerical value.

In the image data storage address table, the storage address in the image ROM 88 and the storage address of the next frame to be displayed next are associated with each frame. The effect display whose effect identifier is the effect pattern 01 when the effect state is 1 is a moving picture by sequentially switching and displaying frame 01, frame 02,..., Frame n1 ₁ -1, frame n1 ₂ on the display screen 5a. is but composed, from the storage address of the example frame 01, the storage address of the frame 01 is an address k1 _1, the frame should be switched displayed from the next frame address to the next frame 01 it can be seen that a frame 02. The table shown in FIG. 12 is referred to in order to obtain the storage address of the image data of frame 01 in the process of S66 of FIG. 19 described later, and the storage address of the image data of the frame to be displayed next in the process of S69. Referenced to get. For example, when the effect state 1, is obtained address k1 ₁ is a storage address in the processing of S66, the address k1 ₂ is obtained as the next frame address in the processing of S69. Each time the process of S69 is repeated, address k ₃ , address k ₃ ,..., Address n1 ₃ are sequentially acquired. The same applies to other combinations of effect states and effect identifiers.

  FIG. 13 is based on a main control circuit 71 that controls game processing operations in the gaming machine 1, peripheral devices (actuators) that are electrically connected to the main control circuit 71, and control commands transmitted from the main control circuit 71. A circuit configuration including the liquid crystal display device 5, the speaker 21, the LED 101, and the sub-control circuit 72 that controls the lamp 102 is shown.

  The main control circuit 71 includes a microcomputer 30 disposed on a circuit board as a main component, and is added with a circuit for random number sampling. The microcomputer 30 includes a CPU 31 that performs a control operation according to a preset program, and a ROM 32 and a RAM 33 that are storage means.

  Connected to the CPU 31 are a clock pulse generation circuit 34 and a frequency divider 35 for generating a reference clock pulse, and a random number generator 36 and a sampling circuit 37 for generating a random number to be sampled. As a means for random number sampling, random number sampling may be executed in the microcomputer 30, that is, on the operation program of the CPU 31. In that case, the random number generator 36 and the sampling circuit 37 can be omitted, or can be left as a backup for the random number sampling operation.

  The ROM 32 of the microcomputer 30 has a probability lottery table (see FIG. 5) that is referred to in the probability lottery process of S16 in FIG. A stop winning combination determination table (see FIG. 6) referred to every time a stop winning combination determination process of S17 in FIG. 16 described later is executed, and is referred to every time a stop table group selection process of S18 is executed. Stop table group selection table (see FIG. 7), stop table (see FIG. 8) referred to in the reel stop control process in S26 of FIG. 16 described later, and reel stop mode according to the stop button operation by the player A stop position search table (not shown) for determining the number, a table number selection table (not shown), and various controls for transmission to the sub-control circuit 72. Command (command) or the like are stored. These commands include a demo display command, a start command, a reel stop permission command, a reel stop command, an all reel stop command, a winning combination command, and the like.

  In the circuit of FIG. 13, the main actuators whose operation is controlled by a control signal from the microcomputer 30 are various lamps (1-BET lamp 9a, 2-BET lamp 9b, maximum BET lamp 9c, etc.) and information display. Unit 18, a hopper (including a drive unit for payout) 40 as a game value giving means for storing medals and paying out a predetermined number of medals according to a command from hopper drive circuit 41, and reels 3L, 3C, 3R There are stepping motors 49L, 49C, and 49R that are driven to rotate.

  Furthermore, a motor drive circuit 39 for driving and controlling the stepping motors 49L, 49C and 49R, a hopper drive circuit 41 for driving and controlling the hopper 40, a lamp driving circuit 45 for driving and controlling various lamps, and a display unit for driving and controlling various display units A drive circuit 48 is connected to the output unit of the CPU 31 via an I / O port (not shown). Each of these drive circuits receives a control signal such as a drive command output from the CPU 31 and controls the operation of each actuator.

  The main input signal generating means for generating an input signal necessary for the microcomputer 30 to generate a control command includes a start switch 6S, a 1-BET switch 11, a 2-BET switch 12, a maximum BET switch 13, There are a C / P switch 14, a medal sensor 22S, a reel stop signal circuit 46, a reel position detection circuit 50, and a payout completion signal circuit 51. These are also connected to the CPU 31 via an I / O port (not shown).

  The start switch 6S detects the operation of the start lever 6. The medal sensor 22S detects medals inserted into the medal insertion slot 22. The reel stop signal circuit 46 outputs a stop signal in response to the operation of each stop button 7L, 7C, 7R. The reel position detection circuit 50 receives the pulse signal from the reel rotation sensor and transmits a signal for detecting the position of each reel 3L, 3C, 3R to the CPU 31. The payout completion signal circuit 51 outputs a signal for detecting completion of the medal payout when the count value of the medal detection unit 40S (the number of medals paid out from the hopper 40) reaches the designated number data.

  In the circuit of FIG. 13, the random number generator 36 generates random numbers belonging to a certain numerical range, and the sampling circuit 37 samples one random number at an appropriate timing after the start lever 6 is operated. Based on the random number sampled in this way and the probability lottery table stored in the ROM 32, one of a plurality of winning combinations is determined. After the winning combination is determined, random number sampling is performed again to select the stop position search table.

  After the rotation of the reels 3L, 3C, 3R is started, the number of drive pulses supplied to each of the stepping motors 49L, 49C, 49R is counted, and the counted value is written in a predetermined area of the RAM 33. From the reels 3L, 3C, 3R, reset pulses are obtained every rotation, and these pulses are input to the CPU 31 via the reel position detection circuit 50. The count value of the drive pulse counted in the RAM 33 is cleared to 0 by the reset pulse thus obtained. As a result, the RAM 33 stores a count value corresponding to the rotation position within the range of one rotation for each of the reels 3L, 3C, and 3R.

  A symbol table (not shown) is stored in the ROM 32 in order to associate the rotational positions of the reels 3L, 3C, and 3R as described above with the symbols drawn on the outer peripheral surface of the reel. In this symbol table, the code numbers sequentially given for each fixed rotation pitch of each of the reels 3L, 3C, and 3R with reference to the rotation position where the reset pulse is generated are provided corresponding to each code number. A symbol code indicating the displayed symbol is associated with the symbol.

  Furthermore, a winning symbol combination table (not shown) is stored in the ROM 32. In this winning symbol combination table, a winning symbol combination, a winning medal payout number, and a winning determination code representing the winning are associated with each other. The winning symbol combination table is referred to when the left reel 3L, the center reel 3C, and the right reel 3R are controlled to stop, and when the winning confirmation is made after all reels are stopped.

  When the winning of the specific winning combination is achieved by the probability lottery process based on the random sampling, the CPU 31 sends a stop command signal sent from the reel stop signal circuit 46 at the timing when the player operates the stop buttons 7L, 7C, 7R. Based on the selected stop position search table, a signal for stopping the reels 3L, 3C, 3R is sent to the motor drive circuit 39.

  If it becomes a stop mode indicating winning of the winning combination, the CPU 31 supplies a payout command signal to the hopper driving circuit 41 and pays out a predetermined number of medals from the hopper 40. At this time, the medal detection unit 40S counts the number of medals to be paid out from the hopper 40, and when the count value reaches a designated number, a medal payout completion signal is input to the CPU 31. As a result, the CPU 31 stops driving the hopper 40 via the hopper drive circuit 41 and ends the medal payout process.

  Next, the control operation of the CPU 31 of the main control circuit 71 will be described with reference to the flowcharts of FIGS.

  First, the CPU 31 performs initialization at the start of the game (S1). Specifically, initialization of the storage contents of the RAM 33, initialization of communication data, and the like are performed. Subsequently, the stored contents of the RAM 33 at the end of the game are erased (S2). Specifically, the data in the writable area of the RAM 33 used in the previous game is erased, the parameters necessary for the next game are written in the write area of the RAM 33, the start address of the sequence program of the next game is designated, I do. Next, it is determined whether or not 30 seconds have elapsed since the end of the previous game, that is, after all the reels 3L, 3C, 3R stop (S3). If this determination is YES, a demo display command for requesting display of a demo image is transmitted to the sub-control circuit 72 (S4). If this determination is NO, the process proceeds to S5.

  Next, the CPU 31 determines whether or not there is a request for automatic medal insertion, that is, whether or not a replay is won in the previous game (S5). When this determination is YES, medals for the insertion request are automatically inserted (S7), and the process proceeds to S8. When the determination in S5 is NO, it is determined whether or not there is an input from the medal sensor 22S or the BET switches 11, 12, and 13 (S6). When this determination is YES, the process proceeds to S8, and when it is NO, the process proceeds to S3.

  Next, the CPU 31 sends a BET command to the sub-control circuit in response to detecting the output of a predetermined signal from the medal sensor 22S, the 1-BET switch 11, the 2-BET switch 12, or the maximum BET switch 13. In order to transmit to 72, predetermined information is memorize | stored in RAM33 (refer FIG. 13) (S8). Subsequently, the CPU 31 determines whether or not there is an input from the start switch 6S based on the operation of the start lever 6 (S9). When this determination is YES, the process proceeds to S10, and when it is NO, S9 is repeated.

  Next, the CPU 31 determines whether or not 4.1 seconds have elapsed since the start of the previous game (S10). When this determination is YES, the process proceeds to S12, and when it is NO, the process proceeds to S11. In the process of S11, the CPU 31 performs a game start waiting time digest process. Specifically, the CPU 31 performs a process of invalidating an input based on an operation for starting the game of the player until 4.1 seconds have elapsed since the previous game started. Subsequently, the CPU 31 outputs a rotation start request command for all reels (S12). The main control circuit 71 commands the start of rotation of the reels 3L, 3C, 3R based on the detection of the rotation start request command for all reels.

  Next, in S13 of FIG. 16, the CPU 31 extracts a random number for lottery, and subsequently sets, for example, a numerical value indicating 30 seconds as an initial value in the timer for monitoring one game (S14). This one-game monitoring timer includes an automatic stop timer for automatically stopping the reel regardless of the stop operation of the player's stop button. In this timer, a numerical value is subtracted as time passes after an initial value is set. The random numbers extracted in the process of S13 are used in the probability lottery process (S16) described later. Subsequently, the CPU 31 executes a gaming state monitoring process (S15). In this gaming state monitoring process, it is determined whether or not the gaming state transition condition is satisfied, the gaming state is transitioned when it is determined that the gaming state transition condition is satisfied, and the gaming state transition condition is satisfied. The current game state is maintained when it is not determined that the player is present. For example, if a BB is won in the previous game, but a missing game occurs, the game state is changed to the general game state until a predetermined condition is met after the current game based on the information won by the BB. Transition from the state to the carryover state.

  Next, the CPU 31 performs a probability lottery process based on the random number value extracted in the process of S13 (S16). This probability lottery process uses a probability lottery table in accordance with the game state, determines which winning combination the random value range belongs to, and determines the winning combination (established flag).

  Next, in S17, the CPU 31 performs a process of determining a winning combination for stopping. In the stop winning combination determination process, the stop winning combination selection table shown in FIG. 6 is used, and the stop winning combination is determined according to the gaming state, the winning combination determined in S16, and the lottery. Subsequently, in S18, the CPU 31 refers to the stop table group selection table (see FIG. 7) and selects a stop table group corresponding to the winning combination for stop. Subsequently, in S19, the CPU 31 selects a winning line (table line selection) for arranging the symbol combinations corresponding to the winning combination for stopping.

  Next, in S20, the CPU 31 sets predetermined information in the RAM 33 (see FIG. 13) in order to transmit a start command to the sub-control circuit 72. The start command includes a winning combination, a winning combination for stoppage, information on a gaming state, and the like. Subsequently, in S21, the CPU 31 waits until 208 milliseconds have elapsed from the start of rotation of the reels 3L, 3C, and 3R, and the reels 3L, 3C, and 3R reach a constant speed of 80 rotations per second. . In S 22, the CPU 31 sets predetermined information in the RAM 33 in order to transmit a reel stop permission command to the sub control circuit 72.

  Next, in S23, the CPU 31 determines whether or not the stop button is turned on. Specifically, it is determined whether any one of the stop buttons 7L, 7C, 7R has been operated. When this determination is YES, the process proceeds to S25, and when this determination is NO, the process proceeds to S24.

  Next, in S24, the CPU 31 determines whether or not the value of the 1-game monitoring timer is 0. When this determination is YES, the process goes to S25, and when it is NO, the process moves to S23.

  Next, in S25, the CPU 31 performs a sliding frame number determination process for determining the number of sliding frames. Specifically, a stop table corresponding to the winning combination for stop determined by the process of S19 is selected, and the number of sliding symbols is determined based on the selected stop table. That is, the number of sliding symbols is determined by the winning combination for stop determined based on the winning combination and the operation timing of the stop buttons 7L, 7C, and 7R. Subsequently, the reel corresponding to the stop button for which the stop operation has been performed is rotated for the number of sliding frames and then stopped (S26), and a reel stop command including information on the reel to be controlled for stop is transmitted to the sub-control circuit 72. In order to do this, predetermined information is set in the RAM 33 (see FIG. 13) (S27). Subsequently, the CPU 31 determines whether or not all reels are stopped (S28). When this determination is NO, the process returns to the processing of S23, and when YES, predetermined information is set in the RAM 33 in order to transmit an all reel stop command indicating that all reels have been stopped to the sub control circuit 72 (S29). .

  Next, in the process of S30 in FIG. 17, the CPU 31 performs a winning search. The winning search is to set a winning flag for identifying a winning combination based on a stop mode of symbols stopped and displayed in the display windows 4L, 4C, and 4R. Specifically, the winning combination is identified based on the code number of the symbols arranged along the center line 8c and the winning determination table. Subsequently, it is determined whether or not the winning flag is normal (S31). When this determination is NO, an illegal error is displayed (S32). When the determination in S31 is YES, the CPU 31 performs medal credit or payout according to the winning combination and the gaming state (S33). Subsequently, the CPU 31 deletes the information on the carryover combination (bonus) stored in the RAM 33 (see FIG. 13).

  Next, the CPU 31 sets predetermined information in the RAM 33 (see FIG. 13) in order to transmit a winning command to the sub-control circuit 72 (S34). The winning command is a command transmitted when it is determined that a winning is made by the process of S27.

  Next, the CPU 31 determines whether or not the gaming state is the BB gaming state or the RB gaming state (S35). When this determination is YES, BB or RB game number check processing is performed (S36). In the case of the BB gaming state, in this game number check process, the number of times that the RB gaming state has occurred, the number of games in the general gaming state during BB, the number of winnings in the RB gaming state, and the number of games in the RB gaming state are checked. In the RB gaming state, in the game number check process, the number of winnings in the RB gaming state and the number of games in the RB gaming state are checked.

  Next, it is determined whether or not it is at the end of the BB gaming state or the RB gaming state (S37). When this determination is YES, the RAM 33 at the end of the BB gaming state or the RB gaming state is cleared (S38). Subsequently, the process proceeds to S2 in FIG. On the other hand, when the determination in S35 is NO, a winning check process for BB and RB is performed (S39). When this process ends, the process proceeds to S2 in FIG.

  Next, with reference to FIG. 18, the periodic interrupt process executed by the CPU 31 of the main control circuit 71 will be described. The periodic interrupt process is invoked and started every 1.1173 milliseconds, for example.

  First, in S41, the CPU 31 (see FIG. 13) saves the register.

  Subsequently, in S42, the CPU 31 performs input port check processing.

  Subsequently, in S43, the CPU 31 performs communication data transmission processing. Various commands stored in the RAM 33 (see FIG. 13) (these commands are the commands stored in the RAM 33 in S4, S8, S12 in FIG. 15, S20, S22, S27, S29 in FIG. 16, and S34 in FIG. 17). Is transmitted from the main control circuit 71 to the sub-control circuit 72.

  Subsequently, in S44, the CPU 31 performs a process of adding 1 to an interrupt counter stored in a predetermined storage area of the RAM 33.

  Subsequently, in S45, the CPU 31 refers to the value of the interrupt counter stored in a predetermined storage area of the RAM 33, and determines whether this value is an even number. When this determination is YES, the process moves to S52, and when it is NO, the process moves to S46.

  Subsequently, in S46, the CPU 31 sets information indicating the reel 3R in the reel identifier. Subsequently, in S47, the CPU 31 performs a reel 3R control process for performing rotation start control, rotation acceleration control, constant speed rotation control, and rotation stop control of the reel 3R.

  Subsequently, in S48, the CPU 31 sets information indicating the reel 3C to the reel identifier. Subsequently, in S49, the CPU 31 performs a reel 3C control process for performing rotation start control, rotation acceleration control, constant speed rotation control, and rotation stop control of the reel 3C.

  Subsequently, in S50, the CPU 31 sets information indicating the reel 3L in the reel identifier. Subsequently, in S51, the CPU 31 performs a reel 3L control process for performing rotation start control, rotation acceleration control, constant speed rotation control, and rotation stop control of the reel 3L.

  On the other hand, in S52, the CPU 31 performs a 7SEG drive control process.

  Subsequently, in S53, the CPU 31 performs various counter subtraction processes. Subsequently, in S54, the CPU 31 performs an electromagnetic counter control process. Finally, in S55, the CPU 31 restores the register and ends the periodic interrupt process.

  Next, processing executed by the sub-control circuit 72 will be described with reference to FIGS.

  FIG. 19 shows information indicating a start command stored in a predetermined area of the RAM 33 (see FIG. 13) in the process of S20 of FIG. 16 to be transmitted to the sub control circuit 72 (see FIGS. 13 and 14). 18 is sent from the main control circuit 71 (see FIG. 13) to the sub-control circuit 72 as a start command in the process of S43, and the flow of the start command receiving process started when the sub-control circuit 72 receives this start command Show. This start command reception process is executed without referring to any information necessary for the progress of the game such as a winning combination included in the start command. That is, a plurality of effects-only modes (effect states) that do not depend on the main control circuit 71 and have different effect frequencies are set in the sub-control circuit 72 (particularly the image control circuit 72a), and effects are displayed based on the result of random lottery. Try to make the contents of the different. Thereby, it is possible to make an illusion that the player can shift to an advantageous gaming state such as a bonus.

  First, in S61, the sub-control circuit microcomputer 81 (see FIG. 14) adds 1 to a counter that stores the sum of the number of games between three bonuses stored in the work RAM 84 (see FIG. 14). Note that the value of the counter that stores the sum of the number of games between the three bonuses stored in the work RAM 84 is inevitably reset when the gaming machine 1 is turned off because the work RAM 84 is a volatile memory. Is done. Therefore, the value of the counter that stores the sum of the previous three bonus games is the cumulative value since the gaming machine 1 was turned on. However, the present invention is not limited to this, and the value of the sum counter of the previous three bonus games is stored in a non-volatile memory such as an EPROM so that the total number of games regardless of whether the gaming machine 1 is turned on or off. The number may be counted.

  Next, in S62, the sub-control circuit microcomputer 81 sums the previous three bonus game numbers stored in the ROM 83 (see FIG. 14) based on the value of the previous three bonus game number sum counter. Referring to the occurrence probability management table (see FIG. 9), the occurrence probability of the sum of the previous three bonus games is searched. The occurrence probability of the sum of the three previous bonus games corresponding to the sum counter value of the previous three bonus games does not exist in the occurrence probability management table of the sum of the previous three bonus games. In some cases, the occurrence probability of the sum of the previous three bonus games is set to zero.

  Next, in S63, the sub-control circuit microcomputer 81 generates the sum of the previous three bonus game counts stored in the work RAM 84 and the previous three bonus game count sums corresponding to this value. Based on the probability, the effect state is determined with reference to the effect state determination table (see FIG. 10). By this process, the stage of the effect display, which is the effect state, is determined as one of the sea, the mountain, and the field.

  Next, in S64, the sub-control circuit microcomputer 81 reads a predetermined random number sampling program from the ROM 83 (see FIG. 14) and starts it to extract one random number.

  Next, in S65, the sub-control circuit microcomputer 81 selects an effect identifier by referring to the effect pattern selection table (see FIG. 11) based on the effect state determined in S63 and the random number extracted in S64. . By this process, any one of effect pattern 01, effect pattern 02,..., Effect pattern 10 is selected as an effect display pattern (situations such as the movement of main character m and stage weather).

Next, in S66, the sub control circuit microcomputer 81 refers to the image data storage address table (see FIG. 12) and stores it in the image ROM 88 (see FIG. 14) based on the combination of the effect state and the effect identifier. The start address of the storage address of the predetermined effect data is set in the work RAM 84. For example, the effect pattern presentation state is 1 when 01 sets the address k1 ₁ is a storage address of the frame 01 in a predetermined area of the work RAM 84 (see FIG. 14). Regardless of the combination of any production state and production pattern, the image data storage address table is searched, the storage address of the frame 01 corresponding to the combination of the production state and the production pattern is extracted, and a predetermined area of the work RAM 84 is obtained. Set to. In this process, based on the storage address of the frame 01 set in a predetermined area of the work RAM 84, the image data specified by the storage address is obtained in the image drawing process in S74 of the RESET interrupt process shown in FIG. It is read from the image ROM 88 (see FIG. 14) and transmitted to one of the buffers secured in the video RAM 89 (see FIG. 14).

  Next, in S67, the sub control circuit microcomputer 81 determines whether or not the read effect data is the last frame. That is, referring to the image data storage address table (see FIG. 12), it is determined whether or not the frame of the effect data that has been read has the next frame address. When this determination is NO, the process is shifted to S68, and when it is YES, this process is ended.

  Next, in S68, the sub control circuit microcomputer 81 determines whether 1/30 milliseconds have elapsed. This 1/30 millisecond is a time required for completing transmission of one frame of the read effect data to the buffer provided in the video RAM 89 (see FIG. 14). That is, when 1/30 milliseconds have elapsed, all of the read effect data for one frame has been transmitted to the buffer provided in the video RAM 89. When this determination is YES, the process proceeds to S69, and when it is NO, S68 is repeated.

  Next, in S <b> 69, the sub control circuit microcomputer 81 sets the storage address of the effect data for the next frame in the work RAM 84. The effect data of the frame scheduled to be read out next to the image data read from the image ROM 88 and transmitted to any buffer secured in the video RAM 89 and transmitted to any buffer secured in the video RAM 89 Is stored in the work RAM 84. When this process ends, the process moves to S67.

  In this way, the start command reception process is executed without referring to any information necessary for the progress of the game, such as a winning combination included in the start command, so that the player can display information implied or suggested by the effect display. It can be interpreted freely. Thus, the player can freely determine whether or not the gaming state is advantageous, and the interest of the game may be improved.

  FIG. 20 shows a flow of a RESET interrupt process executed by the sub control circuit microcomputer 81. The sub control circuit microcomputer 81 whose power is first turned on and the voltage is applied to the reset terminal periodically performs the RESET interrupt processing stored in the ROM 83 (for example, every 2 milliseconds) based on the reset release signal. Configured to do.

  The sub-control circuit microcomputer 81 interrupts the program being executed before calling the interrupt processing, and saves (stores) the address indicating the interrupted position and the values of various registers in a predetermined area of the image control work RAM 83. To do. Further, when the interrupt process is completed, the sub control circuit microcomputer 81 restores the address indicating the position where the saved program is interrupted and the values of various registers, and resumes the process from the point of interruption.

  First, the sub-control circuit microcomputer 81 controls the image control IC 86 to initialize the work RAM 84, the video RAM 89, etc. (S71), and proceeds to S72. In S72, an input monitoring process for monitoring whether or not there is an input from the operation unit 17 (see FIG. 13) or the like is performed, and the process proceeds to S73. In S73, command input processing is performed, and the process proceeds to S74. In S74, an image drawing process is performed, and the process proceeds to S75.

  Here, for one frame of the liquid crystal display device 5 provided in the image control IC 86 for displaying the effect image, two frame buffer areas (hereinafter referred to as frame buffer 1 and frame buffer area) are stored in the video RAM 89. 2). When the effect data of a plurality of effect displays are continuously displayed on the liquid crystal display device 5, the effect data of the plurality of still images to be continuously displayed are alternately displayed in the frame buffer 1 and the frame buffer 2 by background processing. Store temporarily. The temporarily stored effect data of the effect image is alternately transferred from the frame buffer 1 and the frame buffer 2 to the frame by the foreground process. If it is configured to transfer to the frame of the liquid crystal display device 5 without using a buffer, when the effect data of the effect image is composed of a large amount of data, latency occurs during reading, and seamless effect image switching display is performed. I can't. Here, a frame buffer is provided in the video RAM 89. If this frame buffer is a single system, when the production data of a large amount of production images is composed of a large amount of data, latency occurs at the time of transfer. Seamless image switching display cannot be performed. Therefore, the video RAM 89 is provided with two frame buffers, and the effect data of successive effect images is alternately read into the frame buffer, thereby eliminating the latency of image data transfer to the frame with the two buffers. it can. In this way, the image drawing process is performed. Transferring effect data of effect images from the frame buffer 1 and the frame buffer 2 to frames alternately is called bank switching.

  Next, in S75, the sub control circuit microcomputer 81 determines whether or not the VDP counter is 2 or more. The VDP counter is a counter that is incremented by 1 every 1/60 seconds. When this counter becomes 2, 1/60 seconds + 1/60 seconds = 1/30 seconds is the bank switching timing. The image control IC 86 repeats S75 when the determination result is NO, that is, when the VDP counter is less than 2.

  On the other hand, if the determination result is YES, that is, if the VDP counter is 2 or more, the sub control circuit microcomputer 81 moves the process to S76. In S76, the sub-control circuit microcomputer 81 assigns 0 to the VDP counter, transmits a bank switching command to the image control IC 86 (S77), and the image control IC 86 that has received this command performs bank switching. By controlling in this way, the image reproduction time from the start of image reproduction is updated on the condition that the display timing (for example, the timing when the VDP counter becomes 2 or more) elapses, and an image is generated at every predetermined timing become. Note that when the image is generated, a predetermined sound effect corresponding to the image may be generated from the speakers 21L and 21R. Further, at the time of generating the image, the LED 101 and the lamp 102 may be turned on or blinked according to the image. When this process ends, this process ends.

  Next, with reference to FIG. 21, the periodic signal interruption processing from the image control IC executed by the sub control circuit microcomputer 81 will be described. This interrupt process is an interrupt process called in response to reception of a clock signal transmitted from the image control IC 88 every 1/60 seconds. The sub control circuit microcomputer 81 adds 1 to the value of the VDP counter (S81). When this process ends, this process ends.

  Next, a timing chart of image display control processing executed by the image control IC 86 will be described with reference to FIG. In FIG. 22, the timing chart of the frame buffer 1 is shown in the upper stage, and the timing chart of the frame buffer 2 is shown in the lower stage. In addition, the timing charts of the frame buffers 1 and 2 are displayed in the upper part and the chart showing the drawing (preparation) in the lower part.

  In the present embodiment, when displaying an image on the liquid crystal display device 5, the image control IC 86 continuously displays 30 images per second (the display time of one image is 1/30 seconds). Smoothly draw image data. Thereby, a motion is added to a still image such as a character, and a moving image is displayed. As described above, 30 pieces of image data are associated with one second, that is, image data is associated with every 1/30 seconds.

  The video RAM 89 is provided with two buffers, a frame buffer 1 and a frame buffer 2, and an image is displayed by transferring data of one of these two buffers to the liquid crystal display device 5. It is configured.

  Referring to the timing chart showing the upper display in FIG. 22, the effect display is displayed by sequentially switching the image display for 1/30 second, which is switched every 1/30 second interval. Further, referring to the timing chart showing the lower drawing, the drawing is performed between the displays (in the time of 1/30 seconds). Arrows between the frame buffer 1 and the frame buffer 2 indicate bank switching. Here, bank switching refers to switching which of the two buffers provided in the video RAM 89 is to be transferred to the liquid crystal display device 5.

  Referring to FIG. 22, first, image 1 processing is performed in the frame buffer 2. In the image 1 process, first, an image 1 (an image based on image data with a frame number of 1 and so on) corresponding to the determined effect is drawn. Here, drawing is provided in the video RAM 89 after the image control IC 86 starts generating an image based on the image data read from the image ROM 88 in accordance with a program stored in an image control program ROM (not shown). This refers to the time until image data is written in the buffer (here, frame buffer 2). Then, the drawn image 1 is displayed on the liquid crystal display device 5 for 1/30 second by the bank switching described above by operating the register developed in the control RAM 87 of the image control IC 86 from the sub control circuit microcomputer 81.

  When this image 1 processing is completed, bank switching is performed, and image 2 processing is performed in the frame buffer 1. In the frame buffer 1, drawing is performed while the display (image 1) is being performed in the frame buffer 2 (1/30 seconds), and bank switching is performed every 1/30 seconds, so that the display ( Image 2) is performed.

  On the other hand, in this case, display is not performed in the frame buffer 2, and drawing of the image 3 to be displayed next is performed. Then, by switching the bank every 1/30 seconds, the image 3 is displayed.

  As described above, by performing bank switching every 1/30 seconds, the frame buffer 1 or the frame buffer 2 alternately performs image processing (image 2 processing, image 4 processing, image 6 processing in the frame buffer 1). , And image 8 processing, and the frame buffer 2 performs image 1 processing, image 3 processing, image 5 processing, and image 7 processing). In this case, while display is performed in one frame buffer (1/30 second), drawing is performed in the other frame buffer. By switching the bank between the frame buffer 1 and the frame buffer 2 and displaying the images alternately, the display speed of the image is increased and the flicker of the image is eliminated.

  The bank switching timing is transmitted from the image control IC 86 to the sub-control circuit microcomputer 81 when the VDP counter is 2 or more and image data is drawn smoothly as shown in the determination of S75 in FIG. Bank switching is performed every time the received clock signal is received twice (when the VDP counter is updated as 2), that is, every 1/30 seconds.

  As described above, when image data is drawn smoothly, the value of the VDP counter is 0 or 1. However, when image data is not drawn smoothly, image drawing processing ( The value of the VDP counter may already be 2 or more when S74) in FIG. 20 is finished. In this case, the bank is switched when the image drawing process is finished.

  Next, an example of the effect display displayed on the display screen 5a of the liquid crystal display device 5 will be described with reference to FIGS.

  FIG. 23 shows an example of the display mode of the effect display displayed on the display screen 5a when the effect pattern 01 is selected as the effect identifier in the effect state 1, effect state 2, and effect state 3. It is. FIG. 23 (1) shows the effect display in the production state 1, that is, the stage of the sea, FIG. 23 (2) shows the effect display in the production state 2, that is, the stage of the mountain, and FIG. This is the effect display in the effect state 3, that is, the field stage. At this time, the display pattern of the effect display is equally characterized by the effect pattern 01 which is the selected effect identifier (for example, one cloud c is displayed). However, in any display state, the main character m Moves from left to right on the display screen 5a. The same applies to effect identifiers other than the effect pattern 01.

  24 and 25 show the effect display when the effect state is the sea state (that is, the effect state is 1) and the effect pattern 01, the effect pattern 02, ..., the effect pattern 10 is selected as the effect identifier. It is an example of a display mode.

  FIG. 24 (1) is an example of a display form of the effect display when the effect state is the sea state and the effect pattern 01 is selected as the effect identifier. Characterized when one is displayed. FIG. 24 (2) is an example of the display form of the effect display when the effect state is selected as the effect identifier when the effect state is the sea state. Characterized when two c's are displayed. Hereinafter, the display modes of FIGS. 24 (3),..., And FIG. 24 (7) are also characterized by displaying three clouds c,.

  FIG. 25 (8) is an example of the display form of the effect display when the effect state is the sea state and the effect pattern 08 is selected as the effect identifier. Characterized when displayed. FIG. 25 (9) is an example of a display form of the effect display when the effect state is the sea state and the effect pattern 09 is selected as the effect identifier. Characterized when t is displayed. FIG. 25 (10) is an example of the display form of the effect display when the effect state is the sea state and the effect pattern 10 is selected as the effect identifier. Characterized when displayed.

  These effect displays in FIGS. 25 (8), 25 (9), and 25 (10) are effect displays that have enhanced visual and auditory impressions, and are referred to as development effects. Since these development effects are configured so that the probabilities of selection are different depending on the production state in S65 of FIG. 19, the image of each production state held by the player varies depending on the frequency of occurrence of these development effects. be able to. And, the player can freely interpret the information implied and suggested by the combination of the production state and the development production, and can freely interpret whether the game state is an advantageous state. May improve. Even if the selected effect identifier is the effect pattern 08, the sun s is displayed on the effect display, and if the selected effect identifier is the effect pattern 09, thunder clouds and lightning t are displayed on the effect display. If so, the rain cloud r is displayed on the effect display. Accordingly, when the same effect identifier is selected, the player can have almost the same impression on the effect display regardless of the effect state. Thus, when the display frequency of each effect pattern varies depending on the effect state, it can be said that the player tends to store the effect pattern having a high display frequency and the effect state in association with each other.

  The present invention utilizes the above-mentioned tendency of the player, and the effect display displayed based on the effect state and the effect identifier selected by the random number lottery is based on information necessary for the progress of some game. An illusion as if it is displayed can be generated, and the player can freely interpret the meaning of the effect display, thereby enhancing the interest of the game.

  Next, with reference to FIG. 26, the distribution of the occurrence probability P (x) of the sum of the previous three bonus game numbers with respect to the previous three bonus game number sum x will be described. In FIG. 26, the horizontal axis represents the sum x of the previous three bonus games, and the vertical axis represents the occurrence probability y = P (x) of the previous three bonus games.

As described above, the distribution of the occurrence probability P (x) of the sum of the three previous bonus games is almost a normal distribution. The average of this distribution is 733.6119 (game), and the distribution is substantially symmetrical with respect to the sum of the previous three bonus games (with respect to the x-axis), centered on this average. Referring to the inter-bonus game number occurrence probability management table of FIG. 9, when x = 734, P (x) = 9.3865 × 10 ⁻³ , which is the maximum value of the distribution. Then, a line y = 0.000000003426 intersects between x = 502 and 503 and between x = 965 and 966. Let this intersection point be (x ₁ , y ₁ ), (x ₂ , y ₂ ) in ascending order, and perpendicular lines drawn from (x ₁ , y ₁ ) and (x ₂ , y ₂ ) to the x-axis are perpendicular lines 1, The perpendicular 2 is assumed. At this time, y = P (x) is divided into three parts by the perpendicular 1 and the perpendicular 2. Then, from the condition for determining the production state (see FIG. 10), the portion of 1 ≦ x <x ₁ corresponds to the production state 1, the portion of x ₁ ≦ x <x ₂ corresponds to the production state 2, and x ₂ ≦ It can be seen that the state of x corresponds to the production state 3.

Here, when 1 ≦ x <x ₁ or x ₂ ≦ x (that is, according to the occurrence probability management table of the sum of the three previous bonus games in FIG. 9, 1 ≦ x ≦ 502 or 966 ≦ x ), Y = P (x) is the theoretical value of the probability that the sum of the three previous bonus games derived from the bonus (BB and RB) winning probability in the probability lottery table is 733.6119. Is smaller (lower) than (about 0.000000003426), and x ₁ ≦ x <x ₂ (that is, according to the occurrence probability management table of the sum of the number of games between the three bonuses in FIG. 9, 503 ≦ x ≦ 965 )), It can be seen that the value of y = P (x) is larger (higher) than the theoretical value of the probability that the sum of the previous three bonus games is 733.6119. That is, if 1 ≦ x ≦ 502 or 966 ≦ x, the statistical value of the probability that the sum of the three previous bonus games derived from the bonus winning probability in the probability lottery table is 733.6119 is statistical The probability that the total number of games between the three bonuses seen before will be 733.6119 is lower than the theoretical value, and there is a relatively low expectation that the bonus will be won three times. In addition, when 503 ≦ x ≦ 965, the probability that the sum of the number of games between the three previous bonuses statistically will be 733.6119 is higher than the theoretical value, and the three bonuses will be won relatively. The expectation for is high.

  The player plays the game without being aware of such statistical analysis results. However, according to the present invention, by changing the production state based on such a statistical analysis result, whether the state of the game is statistically high or low expectation state, Can be implied and suggested to the player. And if a player interprets this suggestion and suggestion freely, the interest and expectation of a game may increase further.

  In the present embodiment, the occurrence probability of the sum of the previous three bonus game numbers is searched in S62 of the start command reception process (see FIG. 19), and in S63, the previous three bonus game number sum counter The production state is determined on the basis of the value of and the occurrence probability of the sum of the previous three bonus games. However, the production state determination table shown in FIG. It may be adopted instead of the effect state determination table shown, and the effect state may be determined directly from the value of the sum counter of the number of games between the previous three bonuses. In this case, the range of the sum of the previous three bonus games associated with each effect state is 1 to 502, as shown in parentheses on the right side of FIG. The production state is 1 at the time of play, the production state is 2 when the sum of the previous three bonus games is between 503 and 965, and the production state when the sum of the previous three bonus games is 966 or more Becomes 3. Therefore, in this case, since the information on the occurrence probability management table of the sum of the previous three bonus games is incorporated into the effect state determination table, the effect state determination table constitutes the probability distribution management means. become.

  Instead of the previous three bonus games, the average of the previous three bonus games may be used. In this case, the distribution of the average z of the number of games between the previous three bonuses is as follows.

Distribution represented by the above equation (4), the average 244.5373, the dispersion 42.5 ^2, a distribution of approximate a normal distribution. Further, a probability management table for managing the probability corresponding to the average number z of the three previous bonus games calculated by the equation (4) is as shown in FIG. Since the theoretical value of the average occurrence probability of the number of games between the previous three bonuses is 0.004089 (= 67/16384, equal to the bonus winning probability), this value, the value of q (z), and the average of z 244.5373 may be compared, and the effect state may be determined based on the comparison result. According to the determination conditions similar to the effect state determination table of FIG. 10 of the present embodiment, the effect state 1 is determined when 1 ≦ z ≦ 189, the effect state 2 is determined when 190 ≦ z ≦ 299, and 300 ≦ At z, the production state 3 is determined. Similarly to the present embodiment, instead of the probability management table for managing the probability corresponding to the average of the previous three bonus games, the effect state and the average z of the previous three bonus games are associated. The attached production state determination table may be used.

  In the present embodiment, the basic bonus for counting the sum of the number of games between the previous three bonuses is BB or RB, and BB and RB are collectively treated as a bonus. However, the present invention is not limited to this, and the sum of the previous three bonus games may be counted only for BB and / or only for RB, and the effect state may be determined according to these count results. In addition, when only the sum of the number of games between the previous three bonuses is counted for BB only and RB only, and the presentation state is determined according to these count results, it is selected according to BB or RB, respectively. A more advantageous effect state (or an unfavorable effect state) may be finally determined as the effect state of the effect display.

  In the present embodiment, the effect state is determined based on the sum of the number of games played (the number of unit games) until the last (most recent) three bonuses (BB or RB) are won. Not limited to this, the number of games played since the last bonus was won in the sum of the number of games played (the number of unit games) until the last (most recent) bonus (BB or RB) was won It may be determined based on a value obtained by adding.

  In the present embodiment, the number of games between the previous three bonuses is counted. However, the number of games is not limited to three.

  In this embodiment, the production state is determined based on the statistically estimated distribution of the occurrence probability of the sum of the number of games played until the last three bonuses are won. Not limited to the above, the range of the sum of the number of games played until the last three bonuses are won is determined as appropriate, and the last three At least one effect state may be determined from the sum of the number of games played before winning the bonus.

  The effect state of the present embodiment is not limited to the effect display frequency being different, but may be an effect display form (for example, the number of characters (including cases where the characters are the same or different)).

  In the present embodiment, the production contents in each production state are the same except for the background image. However, the production contents are not limited to this, and may be special production contents that are selected only in the production state for each production state. In addition, different production contents may be provided for each production state.

  In the present embodiment, one effect state is selected from three effect states, and one effect identifier (effect pattern) is selected from ten effect identifiers. However, the present invention is not limited to this, as long as one production state is selected from a plurality of production states and one production identifier is selected from a plurality of production identifiers, the production state and the number of production identifiers can be appropriately changed. It is. In addition, the random number range corresponding to each effect state is a matter that can be appropriately changed in design.

  The RB of the present embodiment is a first-type special accessory, and BB is an accessory continuous operation device that continuously operates the first-type special accessory. In the present embodiment, as shown in FIG. 4, medals are not paid out in the unit game in which these RB and BB have won. However, the present invention is not limited to this, and in the unit game in which these RB and BB have won, a predetermined number (for example, 15) of medals may be paid out to the player.
