Abstract

<P>PROBLEM TO BE SOLVED: To reduce processing load for controlling high-probability period. <P>SOLUTION: When a player wins a SB prize during a normal game (a), the game is transferred to an SB game (b) and an RT period (high-probability period) starts. A BB prize and a re-play prize are allocated to a special segment of the SB game. The probability that a re-play segment is selected by internal drawing during the RT period is higher than in the normal game. When the special segment is selected by drawing during the SB game it is transferred to a carryover game (c1) during the RT period. On the other hand in case the player does not win the BB prize during the SB game the game is transferred to the RT period (a1) of the normal game. The probability of re-play segment is selected by internal drawing is high also during this period (a1) to build up expectations of the player winning the BB prize. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a slot machine played with medals or pachinko balls.

  A slot machine generally includes three reels, three reel stop buttons corresponding to each reel, and a start lever for starting a game. When the player depresses the start lever, all the reels rotate at the same time, and each reel stops at the timing when the player depresses each reel stop button. Of the combinations of symbols arranged on the winning line in a state where the reels are stopped, a combination of symbols that gives a game value is called a role. When a combination of symbols composing a combination on the effective winning line is completed, a winning is made, and the player can obtain the number of medals corresponding to the winning combination. That is, when the state where the reels are stopped is a state (predetermined state) that is a combination of symbols constituting the winning combination, the winning combination is awarded and a game value corresponding to the winning winning combination is given.

  Here, the winning is generally determined by two steps. The first step is called internal lottery. In the internal lottery, the lottery is executed at the operation timing of the start lever, which prize group is determined to be won or lost, and internal lottery information indicating the lottery result is generated. Here, the prize group refers to a group of one or more roles. There may be a one-to-one correspondence between a prize group and a combination, or a plurality of combinations may correspond to a single prize group.

  In the second step, the reel stop position is controlled in accordance with the operation of the reel stop button. If the internal lottery information indicates a loss, even if the player operates the reel stop button at the timing when the symbol that constitutes a certain role reaches the valid winning line, the reel stop timing is delayed, The reel is controlled so that the symbols constituting the winning combination do not stop on the valid winning line. The same applies to the combination corresponding to the prize that was not won in the internal lottery. Such control is called kicking control. On the other hand, if the prize group which is an internal lottery is won, even if the operation timing of the reel stop button is slightly early, the pull-in control is performed so that the symbols constituting the role corresponding to the prize group stop on the winning line. The However, if the operation timing of the reel stop button is significantly deviated, no prize will be awarded. In other words, in order for a player to win a prize, it is necessary to win a prize group by internal lottery and align the winning prize group on an effective prize line. Winning any prize group in the internal lottery is called winning, and not winning any prize group is called losing. And, the fact that the symbols stopped on the winning line make up the winning combination is called winning, and the non-winning is not forming the winning combination. In non-winning cases, when the internal lottery result is lost, even if the internal lottery is won, the operation timing of the reel stop button is greatly shifted, so that the role corresponding to the winning prize is not established, so-called Includes missing items.

  In addition to the regular game, such a slot machine can execute multiple types of games such as a big bonus game, a regular bonus game, or a replay time game that has a higher probability of winning a replay prize in an internal lottery than a regular game. is there. The expected value of the number of medals that can be acquired per game is larger in the big bonus game and the regular bonus game than in the normal game. The transition from the base game to the big bonus game is conditional on winning the BB prize, and the transition to the regular bonus game is conditional on winning the RB prize. The internal lottery described above is executed for each game, and it is normal that the internal lottery result is not carried over to the next game. However, if the BB prize or the RB prize is won by the internal lottery, the internal lottery result is continued until winning. Carry over to the game.

  Further, some conventional slot machines shift to a replay time game during a period until a predetermined number of games elapse from the next game won the BB prize. In the replay time game, the regame prize is won with a high probability by internal lottery and the regame prize is won. Accordingly, since the replay time game is continuously won in the replay time game, the player can know that the BB prize has been won by continuously winning the replay prize. Furthermore, a technique for executing a continuous effect by animation or the like on a liquid crystal screen in combination with a replay time game is known. (See Patent Document 1).

  Such a slot machine not only uses the period until a predetermined number of games have passed since the next game won the BB prize as a replay time game, but also has a predetermined probability even in a game that has not won the BB prize. In some cases, a replay time game is started, and a continuous effect is also executed on the liquid crystal screen by animation or the like. That is, in a replay time game started from a game that has not won the BB prize, an effect is executed in the same manner as in the case where the BB prize has been won, even though the BB prize has not actually been won. This is called fake production including the start of a replay time game.

  In this case, in addition to the case where the BB prize is won, the continuous effect is also performed by the fake effect which is not won the BB prize, so the frequency of occurrence of the continuous effect can be increased. In other words, when a re-game prize is continuously won or a continuous performance on the liquid crystal screen is performed, the player plays the replay time game with a sense of expectation that the player may have won the BB prize. Since it can be made to progress, it can be set as a gaming machine that attracts players.

JP2003-305158

However, if the appearance frequency of the fake production is high, the expectation degree of winning the BB prize is not increased even if the continuous production is performed. On the other hand, if the appearance frequency of the fake production is low, the occurrence frequency of the continuous production is low. As a result, there was a problem that the effect of the fake production was reduced.
Furthermore, a lottery means for determining the derivation of the continuous performance is newly required, the control becomes complicated, and two probability values, that is, a probability value that the BB prize is won and a probability value that the false performance appears are prepared. There was a problem that had to be done.

  The present invention has been made in view of the above-mentioned circumstances, and has a processing load for giving a high probability period a meaning of a true production period and a false production period, and managing the high probability period. It is an object of the present invention to provide a slot machine that can be reduced.

  The present invention will be described below. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment.

  In order to solve the above-described problem, the slot machine according to the present invention includes a plurality of display rows (R1, R2, R3) each having a plurality of types of symbols arranged therein and capable of variable display, and an instruction to start the variable display. Start operation means (12) for the player to input, and a plurality of instructions for the player to input instructions to stop the variable display provided corresponding to the plurality of display columns (R1, R2, R3) Stop operation means (13a, 13b, 13c) and a winning line (L1 to L5) consisting of a set of display positions at which symbols are displayed for each of the plurality of display columns (R1, R2, R3), When a stop mode on the winning line (L1 to L5) in a state where variable display of the plurality of display columns (R1, R2, R3) is stopped is a predetermined mode, a prize is won, and according to a prize that is won Predetermined games A value is assigned to the award, and a re-game award that gives a condition for starting the next game without paying a game medium as the game value to be given, and a game type as the game value to be given are transferred. The start prize includes a specific game start prize that starts a specific game that ends in one game, and a special game start prize that starts a special game, and includes a normal game, the specific game, Can carry out multiple types of games including carry-over games and special games that continue from the next game to the game that wins the special game start prize when the game won the special game start prize is not won And has a high probability period in which the probability of winning the re-game prize by lottery is high, and when the special game start prize is won, the game is played from the next game. The type of game is transferred to the special game, and when a predetermined condition is satisfied in the special game, the type of game is transferred to the normal game. When the type is shifted to the special game and a predetermined number of games have elapsed from the specific game as the high probability period, and the next game after the specific game ends becomes the carry-over game, the carry-over game is The game management means (101, S105, S112) that are continuously managed as the high probability period and a plurality of divisions each associated with one or a plurality of prizes or loses are selected and selected by lottery. Generate lottery information indicating the winning or losing of one or more prizes based on the determined division and game type In the base game, a lottery is executed for a plurality of categories including a specific category associated with the specific game start prize and a replay category associated with the replay prize, and the specific category is selected by lottery. The lottery information indicating the winning of the specific game start prize is generated when selected by the above, and the lottery information indicating the winning of the replay prize is generated when the replay division is selected by lottery. In the specific game, a lottery is executed for a plurality of categories including the special category associated with the special game start prize and the replay category, and the special category is selected when the special category is selected by lottery. The lottery information indicating the winning of the game start prize is generated, and when the re-game division is selected by lottery, the lottery information indicating the winning of the re-game prize is generated. In the carryover game, The lottery is executed for a plurality of divisions including the replay division, and when the replay division is selected by lottery, the lottery information indicating the winning of the replay award is generated, and the special game start prize is generated. The lottery information indicating the winning of the current game is held until winning the special game start prize, and the lottery information indicating the winning of the held special game start prize and the lottery information in the current game are combined as new lottery information. In the carryover game of the high probability period, the probability that the replay division is selected by lottery is set higher than that of the carryover game other than the high probability period. In the high probability period of the normal game that shifts when the game start prize is not won, the re-game division is compared with the normal game other than the high probability period. At the timing when each of the lottery means (101, TBL11 to TBL15) and the plurality of stop operation means (13a, 13b, 13c) are operated, the winning line (L1 to L5) is set. ) Draws the symbols constituting the award in which the lottery information located within a predetermined range indicates winning, and stops variable display of the plurality of display rows (R1, R2, R3). Stop control means (101, S109), the stop control means (101, S109), in the carry-over game of the high probability period, the lottery information of both the special game start prize and the re-game prize The figure which comprises the said special game start prize at the timing when each of the said several stop operation means (13a, 13b, 13c) was operated when showing winning. If the pattern and the symbol constituting the re-game award are within the predetermined range from the winning line (L1 to L5) and there is a possibility of winning the re-game award, the symbol constituting the re-game award is The plurality of display columns (R1, R2, R3) are controlled so as to be stopped on the winning lines (L1 to L5).

  According to the present invention, when a specific game start prize (for example, the SB prize of the embodiment) is won in the base game, the next specific game is shifted to a high probability period in which the winning probability of the re-game prize is increased. In the conventional slot machine, there are a first high probability period starting from the next game won the BB prize and a second high probability period started by winning the lottery in a state where the BB prize is not won. Were present. In this case, even if the BB prize is accidentally won during the second high probability period and the first high probability period is started, the first high probability period and the second high probability period There is no relationship between them. Here, the second high-probability period functions as a fake production period in which the re-game prize is drawn with high probability in a state where the BB prize is not selected. On the other hand, in the slot machine according to the present invention, the high probability period is not started on the condition that the special game start prize (BB prize) is won, but on the condition that the specific game start prize is won. A probability period begins. If the special game start prize is won in the specific game, the high probability period functions as a true effect period, while if the special game start prize is not selected in the specific game, the high probability period is set as a false effect period. Function. In other words, in the present invention, one high probability period is started by winning the specific game start prize, and whether the high probability period is set as a true production period or a false production period Leave to the lottery. As a result, it is not necessary to manage two types of high probability periods, so that the processing load can be reduced. Furthermore, since the probability of winning the re-game prize by lottery increases when the high probability period starts, the probability of winning the re-game prize also increases. For this reason, the player can know that it is a high probability period. And since the win probability of a special game is high in the specific game of a high probability period, even if it is a fake production period, a player can be expected. The special game start award is arranged by arranging both symbols so that the range in which the symbols constituting the replay prize can be drawn is the same as or wider than the range in which the symbols constituting the special game start prize can be drawn. Even if the player has been won, the probability of winning the re-game prize increases in the high probability period, and the difficulty of winning the special game start prize can be increased. For example, it is a case where a symbol constituting the re-game award is arranged adjacent to a symbol constituting the special game start prize. The slot machine according to the present invention includes not only medals but also so-called pachilots that can be played with pachinko balls.

  In the slot machine described above, the special category is associated with both the special game start prize and the replay prize, and the lottery means (101, TBL11 to TBL15) Is selected by lottery, the lottery information indicating the winning of both the special game start prize and the replay prize is generated, and the stop control means (101, S109) When the division or the replay division is selected by lottery and the lottery information indicates at least the winning of the replay prize, the re-operation is performed at the timing when each of the plurality of stop operation means (13a, 13b, 13c) is operated. When the symbols constituting the game prize are within the predetermined range from the winning line, the symbols constituting the re-game prize are stopped on the winning line. Wherein the plurality of display columns so that (R1, R2, R3) are preferably controlled. In this case, since both the special game start prize and the re-game prize are assigned to the special category, when the special game start prize is won in the specific game, the re-game prize is always won. Since the regame prize symbol is drawn on the winning line in preference to the special game start award symbol, the difficulty of winning the special game start award in the specific game can be increased. As a result, it is possible to enhance the player's expectation for winning the special game start prize in the high probability period.

  In the above-described slot machine, the award further includes a small role award accompanied by paying out game media as the game value to be given, and the special category includes the special game start award and the small role award. Both prizes are associated with each other, and the lottery means (101, TBL11 to TBL15), when the special division is selected by lottery in the specific game, both the special game start prize and the small role prize. It is preferable to generate the lottery information indicating the winning. In this case, in the specific game, even when winning the small role prize, it is possible to have the possibility of winning the special game start prize, so that the player's expectation can be further enhanced in the high probability period. Can be increased.

  Further, in the slot machine described above, the lottery means (101, TBL11 to TBL15) executes the lottery by including the special category as a lottery target in the base game, and the special category is a lottery in the specific game. It is preferable that the selection probability is set to be higher than the probability that the special division is selected by lottery in the normal game. In this case, since the probability of winning the special game start prize in the specific game is increased, the player's expectation can be enhanced by entering the high probability period.

  In the slot machine described above, the storage means (194) for storing the first notification data indicating the notification contents and the second notification data, and the storage means (194) when the lottery information indicates the special game start prize. ), The notification is executed according to the read first notification data, and when the lottery information does not indicate the special game start prize, the second notification data is stored from the storage means (194). And the notification is executed in accordance with the read second notification data, and the start or start of the specific game is common to both the notification based on the first notification data and the notification based on the second notification data. And a notification means (101, 30) for starting notification when a predetermined number of games have passed.

  According to the present invention, it is possible to execute “true” notification based on the first notification data and “false” notification based on the second notification data. In a conventional slot machine, the notification of “true” is executed after winning the special game start prize, and the notification of “false” is executed by lottery in a game not won the special game start prize. Had decided whether or not. In other words, the trigger for executing “true” notification and the trigger for executing “false” notification are set independently. In contrast, the present invention starts with a game in which “true” notification and “false” notification are shared. This can be a “true” notification when the special game start prize is won in the specific game after winning the specific game start award, and a “false” notification when it is not won. Because it can be done. As described above, since the start of notification is set based on the winning of the specific game start prize, that is, the start of the specific game, it is not necessary to determine when to notify “false” by lottery or the like, and the processing load is reduced. It becomes possible to do.

<2: Configuration of variable reel display device>
FIG. 2 is an explanatory view showing the structure of the reel variable display device RL of the slot machine 1. FIG. 2A shows the structure of the entire reel variable display device RL, and shows a state in which the right reel R3 is removed to show the inside of the reel variable display device. FIG. 2B shows the detailed structure of the right reel R3.

  The reels R1 to R3 are provided with 21 various symbols (symbol number PN = 1) on reel frames 56a to 56c made of transparent ABS resin or the like having a plurality of spoke portions radially extending from the shaft portion and an annular frame. To 21) are printed on the peripheral surfaces of the reel frames 56a to 56c. The reels R <b> 1 to R <b> 3 are inserted along guide rails 51 a to 51 c corresponding to the respective reels provided above and below the case body 50 of the reel variable display device RL, and are accommodated in the case body 50. The reel R3 will be described with reference to FIG. 2B, but the reels R1 and R2 have the same structure. The reel R3 is fixed to the stepping motor 54c and rotates. For the rotation of the reel R3, a stepping motor 54c that rotates once by supplying a pulse of 400 steps is used. By supplying a predetermined pulse, a predetermined symbol can be displayed on the reel window 20. Further, a backlight device 53c provided with LEDs (not shown) is provided so that light can be irradiated from the inside of the reel band 58c. Thus, by irradiating light from the inside of the reel band 58c by the backlight device 53c, the player can make the symbols on the reel band 58c stand out.

  A detection plate 57c is attached to one of the spoke portions, and a reel position detection signal 55c can be output by the reel position detection sensor 55c every time the reel R3 rotates once. The position of the detection plate 57c and the reel band 58c is set so that the symbol number PN = 1 is positioned on the winning line L1 at the center of the reel window 20 when 10 steps are advanced after detecting the reel position detection signal 155c. It is set.

  The reel R3, the stepping motor 54c to which the reel R3 is fixed, the backlight device 53c, and the reel position detection sensor 55c are fixed to the base plate 52c to form one unit. Further, the reel variable display device RL is configured such that the base plate 52c is inserted along the guide rail 51c provided on the case body 50 of the reel variable display device RL and accommodated in the case body 50. Although the stepping motor 54c, the backlight device 53c, the detection plate 57c, the reel position detection sensor 55c, and the reel position detection signal 155c are not shown, in the reel R1, the stepping motor 54a, the backlight device 53a, the detection plate 57a, the reel The reel R2 corresponds to the position detection sensor 55a and the reel position detection signal 155a, and the reel R2 corresponds to the stepping motor 54b, the backlight device 53b, the detection plate 57b, the reel position detection sensor 55b, and the reel position detection signal 155b.

  FIG. 3 is an explanatory diagram showing the arrangement of symbols printed on the reel bands 58a to 58c. Twenty-one symbols are printed at equal intervals on each of the left, middle, and right reels. Since stepping motors 54a to 54c that rotate once by supplying pulses of 400 steps are used, when 21 symbols are arranged, the interval between symbols is 19 steps. Further, since the symbol number PN = 1 is positioned on the winning line L1 at the center of the reel window 20 when 10 steps are advanced after the reel position detection signals 155a to 155c are detected, the reel position detection signal 155a. If 290c is advanced after detecting ~ 155c, the symbol number PN = 2 is positioned on the winning line L1, and if the 48 steps are advanced, the symbol number PN = 3 is positioned on the winning line L1, and if 390 steps are advanced. The symbol number PN = 21 is positioned on the winning line L1. When the processing proceeds beyond step 390, reel position detection signals 155a to 155c are detected again. Thereby, a predetermined symbol can be positioned on the winning line L1 by the number of steps to be advanced based on the timing at which the reel position detection signals 155a to 155c are detected. As shown in parentheses in FIG. 3, the symbol arrangement on the reel band is “01” for the “red 7” symbol and “07” for the “plum” symbol. Stored in data.

<4-2: Slot machine awards and roles>
FIG. 6 is an explanatory diagram for explaining a prize and a combination in the slot machine 1. FIG. 6A shows a configuration of a prize type and a combination (combination of symbols). The slot machine 1 wins when a predetermined symbol combination is aligned on the activated pay line, and a small combination to which a maximum payout of 15 medals is awarded based on the number of payouts determined for each combination. There are a prize, a start prize for starting another type of game from the base game, and a replay prize for giving a game value for starting the next game without a betting operation.

(1) Start Award The BB1 Award (special game start award) is a start award for starting the BB1 game (special game), and a combination of symbols “red 7-red 7-red 7” (“red 7 role”) ”). The BB2 award (special game start award) is a start award for starting the BB2 game (special game), and is a combination of symbols of “white 7-white 7-white 7” as a role (also referred to as “white 7 role”). Composed. The RB award (special game start award) is a start award for starting an RB game (special game), and includes a combination of symbols “BAR-BAR-BAR” (also referred to as “BAR combination”) as a combination. The SB award (specific game start award) is a start award for starting the SB game (specific game), and includes a combination of symbols “Plum-Plum-Bell” (also referred to as “Plumbell role”) as a role. A plurality of types of SB prizes may be provided. Further, this “Plumbell combination” is made to function as a start condition for starting the RT period (high probability period). In addition, the BB1 game and the BB2 game may be games in which the winning probabilities of the internal lottery of the small role award are different from each other, may be different from each other in the number of acquired medals as end conditions, or may be exactly the same. It may be a game. Hereinafter, when it is not necessary to distinguish between BB1 and BB2, they are collectively referred to simply as BB.

(2) Small role award The small role A award is a small role award with 10 medals as a dividend, and consists of a combination of “watermelon-watermelon-watermelon” symbols (also called “watermelon role”). The The small role B award is a small role award with 15 medals as a payout, and includes a combination of symbols “bell-bell-bell” (also referred to as “bell-bell”) as a combination. The small role C award is a small role award that uses two medals as a payout, and includes a combination of symbols “cherry-ANY-ANY” (also referred to as “cherry role”). ANY indicates that any symbol may be used. This “cherry role” is awarded only when the “cherry” symbols of the left reel R1 are aligned on the winning line, and the “cherry” symbol is displayed at the middle display position (M1) of the left reel R1. Wins on the winning line L1 and obtains a payout of two medals, but when displayed at the upper display position of the left reel R1, it wins on the two winning lines of the winning lines L2 and L4. Such a simultaneous winning combination on a plurality of winning lines is called a double winning, and it is possible to obtain a payout corresponding to a maximum of 15 payouts corresponding to the overlapping winning combination. A dividend of medals can be obtained.

(3) Re-game award The re-game award is an award that gives a game value for starting the next game without a betting operation, and a combination of symbols “Plum-Plum-Plum” (“Plum Role”) Consists of).

(4) 100% retractable design The “Plum” design and the “Bell” design are the same “Plum” design and the next “Plum” design on the same reel, as shown in the design layout of FIG. The interval between symbols up to “symbols”, and the interval between symbols from one “bell” symbol to the next “bell” symbol, are arranged within 4 symbols (4 frames). In this slot machine 1, the symbols constituting the prize can be drawn and stopped at the maximum four frames on the winning line by reel stop control described later. Therefore, no matter what timing the player operates the reel stop buttons 13a, 13b, 13c by arranging the “plum” symbol and the “bell” symbol so that the interval is within 4 frames, The symbol can be drawn on the winning line and stopped. Such a “plum” symbol and a “bell” symbol are referred to as 100% drawable symbols or 100% winning symbols. The “bell role” and “plum role”, where all the combinations of symbols that make up the award are 100% drawable symbols, are the reels at any timing in the game where only those awards are won. Even if the stop buttons 13a, 13b, 13c are operated, a prize is always awarded. Prizes composed of such roles are called prizes that can be awarded 100%.

<4-3: Explanation of various games in the slot machine>
FIG. 7 is an explanatory diagram showing the types of games played in the slot machine 1. FIG. 7A shows a transition between a plurality of games performed in the slot machine 1.
(1) Start and end of the BB game When the BB prize is won by an internal lottery during the normal game, and the "Red 7 role" or "White 7 role" is established on the winning line, the BB game starts from the next game To do. The BB game is ended when the acquired number of sheets in the BB game exceeds the specified number. The BB1 game that starts when "Red 7 role" is established has a prescribed number of 465 sheets, and the BB2 game that starts when "White 7 role" is established has a prescribed number of 185 sheets. Note that in the BB game, the number of medals required to start the game is set to one.
(2) BB carryover game If the “Red 7 role” or “White 7 role” is not established on the winning line even if the BB prize is won in the internal lottery during the normal game, the relevant role is established after the next game. Until it wins, it becomes a BB carryover game in which the winning flag of the BB prize is carried over. When the winning combination is established on the winning line while the BB carryover game is being executed, the BB game starts from the next game. In the carryover game, the number of medals required to start the game is set to three.

(3) Start and end of the RB game When the RB prize is won by the internal lottery during the normal game and the “BAR combination” is established on the winning line, the RB game starts from the next game. A maximum of 12 RB games are played, and when the RB game is won eight times during execution, the RB game is terminated. Note that in the RB game, the number of medals required to start the game is set to one.
(4) RB carryover game If the “BAR role” is not established on the winning line even if the RB prize is won in the internal lottery during the normal game, the RB award will continue until the relevant game is established and won. It will be an RB carryover game that carries the winning flag. When the winning combination is established on the winning line while the RB carryover game is executed, the RB game starts from the next game. In the carryover game, the number of medals required to start the game is set to three.

(5) SB game During the regular game, the SB prize is won by an internal lottery. When the “Plumbell” is established on the winning line and the prize is won, the SB game (specific game) starts from the next game. End. Since the “Plumbell role” is made up of 100% winning symbols, the SB award is always won in games where the SB award is won. Further, in this example, the establishment of the “Plumbell role” that is the winning of the SB prize is the start condition of the RT period over five games. For this reason, in the SB game, the winning probability of the re-game prize is higher than that in the normal game. Further, as will be described later, in the SB game, an internal lottery is executed so that the winning flag is set simultaneously with the replay prize for the BB prize and the RB prize. Therefore, in the SB game, the re-game prize is won frequently, and the game becomes easy to win the re-game prize. Note that in the SB game, the number of medals required to start the game is set to one.

(6) Normal game RT period (high probability period)
If the BB game or the RB award start prize is not won in the SB game, after the end of the SB game, the normal RT period is set and the RT period is continued. When the RT period (4 games) ends, the next game returns to the normal game.
(7) BB carryover game RT period (high probability period)
When the BB prize is won in the SB game, the re-game prize is also won at the same time. Therefore, stop control giving priority to the re-game prize is executed. Therefore, as shown in FIG. 7B, after the SB game ends, the BB carryover game RT period is entered. This BB carryover game RT period is a game in which the winning probability of the re-game award is set higher than that of the BB carryover game, and the RT period started from the SB game is continued. The RT period ends when the RT period (4 games) in the BB carryover game ends or when the BB prize is won during the game. That is, when the RT period ends, the game returns from the next game to the BB carryover game, and when the BB prize is won and ends, the game shifts from the next game to the BB game. The RT period (high probability period) is managed by the RT count number indicating the number of remaining games (counting means).
(8) RB carryover game RT period (high probability period)
When the RB game is won in the SB game, the re-game prize is also won at the same time, so stop control is performed with priority on the re-game prize. Therefore, after the end of the SB game, the RB carryover game RT period is entered. This RB carryover game RT period is a game in which the winning probability of the re-game award is set higher than that of the RB carryover game, and the RT period started from the SB game is continued.

(9) Modification Example of BB FIG. 7C is a modification example of the BB game performed in the slot machine 1. When the BB prize is won by the internal lottery during the normal game and the BB role is established on the winning line and the prize is won, the BB game is started from the next game, and the BB normal game is started first. The BB normal game is a game in which the winning probability of the RB prize varies as compared with the normal game. During the BB regular game, the RB prize is won by internal lottery. When the RB role is established on the winning line and the prize is won, the RB game (RB game in the BB) is started from the next game. End the game. The BB game is terminated when the number obtained in the BB game reaches the prescribed number or exceeds the prescribed number in the next payout.

  In the slot machine 1, the game type is managed by a game type flag shown in FIG. When bit 1 of the game type flag is set to “1” as the BB1 game in-progress flag, it indicates that the BB1 game is in progress, and when bit 1 is set to the BB2 game in-progress flag and “1” is set, it indicates that the BB2 game is in progress Show. Further, when bit 2 is set as an RB game in-progress flag and set to “1”, it indicates that an RB game is in progress. When bit 3 is set to “1” with the SB game in-progress flag set to “1”, it indicates that the SB game is in progress. When the bit 5 is set to “1” as the RB carryover game flag, it indicates that the RB carryover game is in progress. When bit 6 is set to “1” as an RT period flag, the RT period is indicated. When only this RT period flag is set, it indicates the normal game RT period, and when it is set at the same time as the SB game flag, it indicates the SB game RT period and is set at the same time as the carryover game flag. Show the carry-over RT period. If any bit indicates “0” without being set, it indicates that the game is in progress. In addition, during the BB RB game, bit 0 or bit 1 and bit 2 are simultaneously set to “1”. Hereinafter, when it is not necessary to distinguish between the BB1 in-game flag and the BB2 in-game flag, they are collectively referred to simply as the BB game flag.

<5: Operation of slot machine>
Next, details of the overall operation of the slot machine 1 will be described. The CPU 101 performs an initialization process after turning on the power, and executes the process of the flowchart shown in FIG.

<5-1: 1 game flow>
FIG. 8 is a flowchart showing the contents of the flow of one game. First, the CPU 101 determines based on the medal insertion signal 160 or the bet operation instruction signals 111a to 111c whether or not an insertion bet operation by inserting a medal or a storage bet operation by pressing the bet button 11 has been performed, (S100). If any signal is detected, the CPU 101 proceeds to the next step, determines whether a start lever operation has been performed based on the start operation instruction signal 112, and waits until a signal is detected (S101). If the CPU 101 detects a signal, it prohibits the betting operation (S102). More specifically, the solenoid of the medal selector device is turned off by the medal block signal 161, the passage route of the medal selector device is switched, and the game medal is discharged to the medal tray 40 even when it is inserted from the medal insertion slot 10. Also, bet operation instruction signals 111a to 111c are not accepted.

  Next, the CPU 101 sequentially increments every 10 nanoseconds in the range of 0000H to 3FFFH, acquires a counter value from the counter circuit that makes one round in about 1.6 milliseconds via the input / output port 107, and sets it as a random value. (S103). Next, referring to each game type flag, a prize lottery table corresponding to the type of the game is selected (S104). The CPU 101 uses the selected prize lottery table to determine which numerical range set for each lottery category on the prize lottery table the acquired random number value belongs to, and for the prize corresponding to the lottery category A winning flag is set (S105). Next, the CPU 101 outputs the RT count number and winning information data indicated by the winning flag to the data sending circuit 106 and notifies the sub CPU 191 of the contents. Next, a stop link table to be referred to in stop control is selected based on the winning flag set in step S105 (S106). The detailed data structure of the stop link table will be described later (see FIG. 14).

  In the slot machine 1, the elapsed time required for one game is measured in order to prevent the player from consuming a lot of game medals in a short time. In this embodiment, the minimum consumption time of one game is 4.1 seconds, and 15 games or more cannot be executed in one minute. Specifically, referring to a timer value that counts down to 0 every 2 milliseconds indicating the elapsed time of one game, when the timer value reaches 0, the timer value is an initial value corresponding to 4.1 seconds Reset to the value (2050). Therefore, even if the start lever is operated in step S101, if 4.1 seconds have not elapsed since the start of the rotation of the reel of the previous game, the reels R1 to R3 are in a standby state without being rotated and are in a standby state. The player is informed by a lamp or sound (S107). Then, the CPU 101 supplies pulses to the reel drive signals 154a to 154c and drives the stepping motors sequentially or simultaneously to rotate the three reels (S108). Specifically, each of the reel drive signals 154a to 154c includes a plurality of drive signal lines for exciting a plurality of winding phases, and a reel is supplied by supplying a pulse signal to each drive signal line in a predetermined phase pattern. Rotate.

  Next, the CPU 101 shifts all three reels R1 to R3 to a constant rotational speed through an acceleration period of 10 steps. It is detected that the three reels R1 to R3 have reached a constant rotational speed, this detection time is set as a reference time, measurement of the remaining time until the automatic stop time elapses from this reference time is started, and the stop buttons 13a to 13 The LED built in the stop button is turned on to notify that 13c can be received. Specifically, it is detected that the pulse width of the reel drive signals 154a to 154c supplied to the drive signal line of the stepping motor is constant, and this detection time is used as a reference time, and counts down to 0 every 2 milliseconds. A value indicating a predetermined automatic stop time (for example, 30 seconds) is set as an initial value of the timer value. At this time, the LED built in the stop button corresponding to each reel is turned on.

  In addition, as a method for detecting that the three reels R1 to R3 have reached a constant rotational speed, a predetermined time after the start of reel rotation or a predetermined time after the start of reel rotation (predetermined number of interruptions). After the occurrence of a predetermined number of steps from the start of rotation of the reel, or a predetermined time after the start of rotation of the reel ( After a predetermined number of interruptions), a method that considers that a certain rotation speed has been reached when a predetermined time has elapsed, a predetermined number of steps have elapsed, a stepping motor has made one revolution, or an index has been detected. There is. That is, in this embodiment, the time point at which the constant rotational speed is detected is set as the reference time point, but the time point at which it is considered that the constant rotational speed is reached may be set as the reference time point.

  Then, the CPU 101 performs a reel stop process for stopping the three reels R1 to R3 (S109). As will be described in detail later, in the reel stop process, when stop operation instruction signals 113a to 113c are detected and the stop button is operated by the player, the stop button is selected based on the stop link table selected in step S106. The symbol number PN to be stopped is determined from the symbol position on the reel obtained at the operation timing and the stop data in the stop data table group, and the braking force is applied by all-phase excitation that excites all winding phases simultaneously. Reel stop processing is performed for each reel to rotate and stop at a inertia equivalent to 15 steps from the start of excitation. When the automatic stop time elapses from the reference time point (when the remaining time runs out), the stop operation is performed. The reels that were not performed are automatically stopped.

  Next, when all the reels are stopped, the CPU 101 determines whether or not a winning combination has been established on a valid winning line (S110), and if it has won, a game value set for each winning combination is given. To do. Next, the CPU 101 performs a game end determination process (S111). In this game end determination process, in the BB1 game, it is determined whether or not the acquired number of games during the BB1 game has exceeded 465 as an end condition. Further, in the BB2 game, it is determined whether or not the acquired number of games during the BB2 game has exceeded 185 as an end condition. In the RB game, it is determined whether the winning condition is eight times during the RB game or whether 12 RB games have passed. Further, in the SB game, it is determined whether one SB game has elapsed as an end condition. When these end conditions are satisfied, the respective in-game flags (BB1 in-game flag, BB2 in-game flag, RB in-game flag, or SB in-game flag) are cleared to end the game. In the RT period, the RT count is subtracted, and when the RT count reaches 0, the RT period flag is cleared and the RT period is ended.

  Subsequently, a winning flag clear process is performed (S112). Here, if the winning flag established in the game is a start prize that the flag can be carried over, the winning flag is cleared only when winning, and the winning flag is not cleared if it is missed without winning. . On the other hand, if the winning flag established in the game is a start prize or a small role award that the flag cannot carry over, the winning flag is cleared regardless of whether the winning prize is won or not missed. Next, the CPU 101 determines whether or not a re-game prize has been won (S113). If it is determined that a prize has been won, automatic bet processing is performed (S100a), and the process returns to step S101. If it is determined that the player has not won, the prohibition of the betting operation performed in step S102 is canceled (S114) so that the game medal can be inserted or the input of the bet button 11 can be accepted, and the next game is started. Therefore, the process returns to step S100.

<5-2: Prize lottery table determination process>
FIG. 9 is an explanatory diagram showing an example of an internal lottery using the prize lottery table selected in the prize lottery table determination process in step S104. During the normal game, selection probabilities for determining any of the lottery categories from “lottery category 1” to “lottery category 9” by internal lottery are “112/16384”, “150/16384”, “1400 / 16384 ”,“ 200/16384 ”,“ 25/16384 ”,“ 30/16384 ”,“ 15/16384 ”,“ 2250/16384 ”,“ 12202/16384 ”, and data indicating the selection probability is stored An internal lottery is performed using the prize lottery table TBL11, and a prize winning flag corresponding to the selected lottery category is set. The selection probability of each lottery section is synonymous with the winning probability of a prize corresponding to each lottery section. In addition, the selection probability of “lottery category 9” means the probability of losing which is not any prize.

  In the prize lottery table TBL11, lottery category data “112” of “lottery category 1” is stored in the top storage area of the prize lottery table indicated by the table storage address ADR11, and the obtained random number value belongs to the range of 0 to 111. If it is, it indicates that the SB prize is won. The lottery category data “150” of “lottery category 2” is stored in the storage area offset by 02H from the top of the prize lottery table, and if the obtained random number value belongs to the range of 112 to 261, the small role C prize Indicates that you have won. The lottery section data “1400” of “lottery section 3” is stored in the storage area offset by 04H from the head of the prize lottery table. If the obtained random number value falls within the range of 262 to 1661, the small role B prize Indicates that you have won. In the storage area offset by 06H from the top of the prize lottery table, lottery classification data “200” of “lottery classification 4” is stored, and when the obtained random number value belongs to the range of 1662 to 1861, the small role A prize Indicates that you have won. The lottery section data “25” of “lottery section 5” is stored in the storage area offset by 08H from the top of the prize lottery table. If the obtained random number value falls within the range of 1862 to 1886, the RB prize is won. Indicates that The lottery section data “30” of “lottery section 6” is stored in the storage area offset by 0 AH from the top of the prize lottery table. If it belongs to the range of 1887 to 1916, it indicates that the BB2 prize is won. The lottery section data “15” of “lottery section 7” is stored in the storage area offset by 0CH from the head of the prize lottery table. If the obtained random number value falls within the range of 1917 to 1931, the BB1 prize is won. Indicates that The lottery section data “2250” of “lottery section 8” is stored in the storage area offset by 0EH from the top of the prize lottery table, and if the obtained random number value belongs to the range of 1932 to 4181, it will be a re-game prize Shows that you have won. Note that the lottery category data of “lottery category 9” is not stored, and the obtained random number value is sequentially compared with the lottery category data from “lottery category 1” to “lottery category 8” and belongs to any range. If it is determined that it is not, it is regarded as “lottery category 9” and is lost. Prize lottery tables TBL12 to 16 described later are also the same as the prize lottery table TBL11 except that prizes (one or more) and numerical values included in the lottery classifications to be drawn are different.

  The result of the internal lottery is stored by a winning flag shown in FIG. Bit 0 of the winning flag indicates the BB1 winning flag, bit 1 indicates the BB2 winning flag, bit 2 indicates the RB winning flag, and bit 3 indicates the SB winning flag. Bit 8 indicates a replay winning flag, bit 9 indicates a small role A winning flag, bit 10 indicates a small role B winning flag, and bit 11 indicates a small role C winning flag. When the flag is set to “1”, the winning of the corresponding prize is shown. Further, the BB 1-2 winning flag and the RB winning flag are carried over with the winning flag set in the next game until the winning is made when the corresponding prize cannot be won in the game won by the internal lottery. When a game with a flag carried over from the previous game is won and another prize is won in the internal lottery, a plurality of flags of the flag carried over and the newly won flag are set. In addition, as a result of the internal lottery, a flag is managed as information on whether or not a prize is assigned to each bit. However, if it is “01H”, a re-game prize is won, and if “02H”, a small role A prize is won. You may make it manage with a numerical value.

  FIG. 10 is an explanatory diagram showing the relationship between the prize lottery table selected in the prize lottery table determination process in step S104 and the type of game being executed. FIG. FIG. 10B shows a relationship between a game type and a flag that is set according to the game type. FIG. 11 is a flowchart showing the contents of the prize lottery table determination process corresponding to the game type in step S104. First, the CPU 101 refers to the SB game in-progress flag to determine whether or not the SB game is in progress (S104a). If it is determined that the SB game is in progress, the award lottery table TBL16 indicated by the ADR 16 is selected (S104a1). When it is determined in step 104a that the SB game is not being played, it is determined whether or not the RB game is being played with reference to the RB game flag (S104b). The table TBL15 is selected (S104b1). If it is determined in step 104b that the RB game is not being played, it is determined whether or not the BB game is being played with reference to the BB game flag (S104c). If it is determined that the BB game is being played, the prize lottery indicated by the ADR 15 is determined. The table TBL15 is selected (S104c1). In the present embodiment, the same lottery table is selected during the BB game and during the RB game. If it is determined in step 104c that the BB game is not being played, it is determined whether or not the RB carryover game is being performed with reference to the RB carryover game flag (S104d). It is determined with reference to the period flag whether or not it is during the RT period (S104d1). If it is determined in step 104d1 that it is during the RT period, the prize lottery table TBL14 is selected, and if it is determined that it is not during the RT period, the prize lottery table TBL13 is selected. If it is determined in step 104d that the RB carryover game is not in progress, it is determined whether or not the BB carryover game is in progress with reference to the BB carryover game in-progress flag (S104e). It is determined with reference to the RT period flag whether or not it is during the RT period (S104e1). If it is determined in step 104e1 that it is during the RT period, the prize lottery table TBL14 is selected, and if it is determined that it is not during the RT period, the prize lottery table TBL13 is selected. In this embodiment, the same lottery table is selected during the BB carryover game and during the RB carryover game. If it is determined in step 104e that the BB carryover game is not in progress, it indicates that the base game is in progress, and it is further determined by referring to the RT period flag whether it is in the RT period (S104f). If it is determined in step 104f that it is during the RT period, the prize lottery table TBL12 is selected (S104f1), and if it is determined that it is not during the RT period, the prize lottery table TBL11 is selected (S104f2).

  The winning probability of the replay prize during the normal game RT period is “14451/16384”, which is set higher than the winning probability during the normal game. On the other hand, the winning probability of prizes other than the re-game prize during the normal game RT period (BB1 prize, BB2 prize, RB prize, SB prize, small role A prize, small role B prize, small role C prize) The same as the winning probability of. Therefore, the probability of being classified as a loss during the normal game RT period is lower than the probability during the normal game, as the winning probability of the replay prize is high. In addition, the winning probability of the re-game prize during the BB / RB carryover game RT period is “14451/16384”, which is set higher than the winning probability during the BB / RB carryover game. On the other hand, the winning probability of prizes other than the re-game prize during the BB / RB carry-over game RT period (BB 1 prize, BB 2 prize, RB prize, SB prize, small role A prize, small role B prize, small role C prize) It is set to be the same as the winning probability in the BB / RB carryover game. Therefore, the probability of being classified as lost during the BB / RB carry-over game RT period is lower than the probability during the BB / RB carry-over game, as the winning probability of the re-game prize is high. Also, the winning probability of the re-game prize during the normal game RT period is the same as the winning probability of the re-game prize during the BB / RB carry-over game RT period. This is because it is difficult for the player to specify which game the winning probability of the re-game prize is set to be the same winning probability. Therefore, the winning probability of the re-game award may be varied to such an extent that the player cannot clearly identify which game it is.

  The winning probability of prizes other than the start prize in the BB / RB carryover game (small role A prize, small role B prize, small role C prize, replay prize) is set to be the same as the winning probability in the normal game. . Further, the winning probability of the start prize (BB 1 prize, BB 2 prize, RB prize, SB prize) in the BB carry-over game and the RB carry-over game is set to “0/16384” and is not included in the lottery for the internal lottery.

  During the BB / RB game, the winning probabilities for determining any one of the small role C prize, the small role B prize or the small role A prize by lottery are “150/16384”, “14500/16384”, “200 / 16384 "and the winning flag of the winning prize is set. As described above, during the BB game and during the RB game, the winning probability of the small role B prize is higher than that during the normal game and the carry-over game. In this embodiment, in the BB game, only the small role B prize has a high probability of winning, but the small role A prize to small role C prize are all high probability, or the small role A prize to small role C prize are normal games. Alternatively, a small winning prize dedicated to the BB game or the RB game may be provided with the same winning probability as the carryover game. In any case, during the BB game, the combination probability of the small role award (the sum of the winning probabilities of a plurality of small role awards) is increased as compared with the normal game and the carryover game.

  When “lottery category 5” is selected by the internal lottery during the SB game, the winning flags of both the RB prize and the replay prize are set. When “lottery category 6” is selected by internal lottery, winning flags for both the BB2 prize and the replay prize are set. When “lottery category 7” is selected by internal lottery, winning flags for both the BB1 prize and the re-game prize are set. In addition, the winning probability of the replay award during the SB game is “10107/16384”, which is set higher than the winning probability during the normal game. The winning of the SB game triggers the start of the RT period (5 games), and the RT period of the first game is the SB game. The RT period after the second game is a normal game RT period or a BB / RB carryover game RT period. Therefore, the RT period is executed across the SB game and the base game or the BB / RB carryover game. In each game during the RT period, the winning probability of the re-game award is set to a high probability compared to the winning probability in the normal game, and it is avoided or difficult to select “lottery category 9” by internal lottery. It is preferable to do. In the normal game or the like, the number of medals required to start the game is set to 3, whereas in the SB game, it is set to 1. In this example, according to the number of medals required to start the game, the correspondence of which prize winning flag is set according to the lottery classification is switched.

<5-3: Winning flag set processing>
FIG. 12 is a flowchart showing the contents of the winning flag setting process in step S105. In this winning flag setting process, a winning flag effective for the game is set from the acquired random number and the prize lottery table corresponding to the type of game determined in step S104. If the prize lottery table is different, the winning flag to be set is also different. Even if the same prize lottery table is different, the winning flag to be set is different. When there is a winning flag carried over from the previous game, the winning flag is set by combining the winning flag carried over with the winning flag set from the random value acquired in the game. Also, during the SB game, among the lottery sections, lottery sections 5 to 7 set a plurality of winning flags corresponding to the lottery sections.

  First, the CPU 101 determines whether or not the acquired random number value belongs to the “lottery category 1” range of the prize lottery table (S105a), and if it is determined that it belongs to the “lottery category 1”, the SB winning flag Is set (S105a1).

  Next, the CPU 101 determines whether or not the acquired random number value belongs to the “lottery category 2” range of the prize lottery table (S105c). The C winning flag is set (S105c1).

  Next, the CPU 101 determines whether or not the acquired random number value belongs to the “lottery category 3” range of the prize lottery table (S105d). The B winning flag is set (S105d1).

  Next, the CPU 101 determines whether or not the acquired random number value belongs to the “lottery category 4” range of the prize lottery table (S105e). A winning flag is set (S105e1).

  Next, the CPU 101 determines whether or not the obtained random number value belongs to the “lottery category 5” range of the prize lottery table (S105f). If it is determined that it belongs to the “lottery category 5”, the SB game It is determined whether it is medium (S105f1). If it is determined that the SB game is in progress, an RB winning flag and a re-game winning flag are set (S105f2). That is, when it is determined that the SB game is being played, the RB winning flag and the replay winning flag are set simultaneously. If it is determined that the SB game is not being played, an RB winning flag is set (S105f3). At this time, the replay winning flag is not set. In each carryover game, BB game, and RB game, the RB prize lottery classification data is “0” and is not included in the lottery for the internal lottery.

  Next, the CPU 101 determines whether or not the acquired random number value belongs to the “lottery category 6” range of the prize lottery table (S105g). If it is determined that it belongs to the “lottery category 6”, the SB game It is determined whether it is medium (S105g1). If it is determined that the SB game is in progress, the BB2 winning flag and the replay winning flag are set (S105g2). That is, when it is determined that the SB game is being played, the BB2 winning flag and the replay winning flag are set simultaneously. If it is determined that the SB game is not being played, the BB2 winning flag is set (S105g3). At this time, the replay winning flag is not set. In each carryover game, BB game, and RB game, the lottery classification data of the BB2 prize is “0” and is not included in the lottery for the internal lottery.

  Next, the CPU 101 determines whether or not the acquired random number value belongs to the “lottery category 7” range of the prize lottery table (S105h). It is determined whether it is medium (S105h1). If it is determined that the SB game is in progress, the BB1 winning flag and the replay winning flag are set (S105h2). That is, when it is determined that the SB game is being played, the BB1 winning flag and the replay winning flag are set simultaneously. If it is determined that the SB game is not being played, the BB1 winning flag is set (S105h3). At this time, the replay winning flag is not set. In each carryover game, BB game, and RB game, the lottery classification data of the BB1 award is “0” and is not included in the lottery target of the internal lottery.

  Next, the CPU 101 determines whether or not the acquired random number value belongs to the “lottery category 8” range of the prize lottery table (S105k). A winning flag is set (S105k1). In the BB game and the RB game, the lottery classification data of the replay prize is “0” and is not included in the lottery target of the internal lottery. Thereafter, this process is terminated.

<5-4: Stop link table selection process>
FIG. 13 is a flowchart showing the contents of the stop link table selection process in step S106. In this stop link table selection processing, stop link tables TBL21 to TBL29 set for each award used in stop control are selected from the winning flags set in step S105, and a stop data table for specifying the display position according to the stop operation sequence is created. Stop display while selecting sequentially. FIG. 14 is an explanatory diagram of the data structure of the stop link table. The stop link table is categorized for each prize to be drawn in the internal lottery. FIG. (A) shows the stop link table TBL21 for replay, and FIG. (B) shows the stop link table TBL28 for SB. FIG. 4C shows the stop link table TBL27 for BB1. The stop link tables TBL21 to TBL29 are arranged such that (a) the first stop operation is the left reel R1, (b) the first stop operation is the middle reel R2, and (c) the first stop is performed, depending on the reel that is stopped first. The operation is divided into three parts, that is, the right reel R3, and further, it is divided according to whether the symbols constituting the prize are displayed at the display positions of the upper, middle, or lower stages.

  The table structure will be described with reference to the replay stop link table TBL21 shown in FIG. In the game won for the replay prize, the data group (a) of TBL21 is selected when the first stop operation is the left reel R1, and the data group (b) of TBL21 is selected when the first stop operation is the middle reel R2. When the first stop operation is the right reel R3, the data group (c) of the TBL 21 is selected.

  Next, the stop data table to be used for the first left reel R1 is selected depending on whether the “plum” symbols constituting the combination relating to the replay prize are displayed on the upper, middle or lower level. Here, the display position of the “Plum” symbol is selected according to the symbol position corresponding to the stop operation timing of the player, and the display position of any one of the upper, middle and lower levels is set in advance. For each symbol position according to the method and the player's stop operation timing, it is determined whether the “plum” symbol should be displayed at the upper, middle or lower display position, and there are multiple display position candidates. There is a method of determining by lottery. In the case of a game where the winning line is one line (L1 line), the display position is determined as the middle stage.

  For example, when the left reel R1 is selected in the first stop operation and the data group (a) of TBL21 is selected, the stop data table TBL102 is selected when the “plum” symbol is displayed at the upper display position of the left reel R1. When displaying at the middle display position, the stop data table TBL101 is selected, and when displaying at the lower display position, the stop data table TBL103 is selected. Here, when the stop data table TBL103 is selected and the “plum” symbol is displayed at the lower display position, the lower display position of the left reel R1 is a candidate for the L3 line and the L5 line included in the winning line. Therefore, when the middle reel R2 is selected in the second stop operation, either the stop data table TBL203 displayed at the lower display position or the stop data table TBL201 displayed at the middle display position is a selection candidate. . On the other hand, when the right reel R3 is selected in the second stop operation, either the stop data table TBL303 displayed at the lower display position or the stop data table TBL302 displayed at the upper display position is a candidate for selection. When there are a plurality of selection candidates, the selection is made by lottery or the like as in the case of the left reel R1. Here, the case where the stop data table TBL201 is selected and the “plum” symbol is displayed at the middle display position of the middle reel R2 will be described. In the third stop operation, the stop data table TBL302 that becomes the upper display position of the remaining right reel R3. Is selected, and "Plum combination" is displayed on the winning line L5.

  When the middle reel R2 is selected in the first stop operation and the data group (b) of the TBL 21 is selected, only the TBL 201 that displays the “plum” symbol at the middle display position can be selected. In order to prevent the “cherry” symbol and the “plum” symbol from being displayed at the same time on the left reel R1, if the “plum” symbol is displayed at the upper or lower display position on the left reel R1, the lower or upper symbol is displayed. This is because a “Cherry” symbol may be displayed at the display position, so that a winning line including the upper or lower display position of the left reel R1 cannot be selected. TBL101 is selected when the left reel R1 is selected in the second stop operation, and TBL301 is selected in the third stop operation. When the right reel R3 is selected in the second stop operation, TBL301 is selected, and in the third stop operation, TBL101 is selected. As a result, “Plum combination” is displayed on the winning line L1.

  For the same reason, when the right reel R3 is selected in the first stop operation and the data group (c) of the TBL 21 is selected, only the TBL 301 that displays the “plum” symbol at the middle display position can be selected. TBL101 is selected when the left reel R1 is selected in the second stop operation, and TBL201 is selected in the third stop operation. TBL201 is selected when the middle reel R2 is selected in the second stop operation, and TBL101 is selected in the third stop operation. As a result, “Plum combination” is displayed on the winning line L1.

  In the stop link table TBL28 for SB shown in FIG. 14B, when the data group (a) of TBL28 is selected, “Plumbell combination” is displayed on any winning line (L1 to L5). When the data group (b) of TBL 28 or (c) of TBL 28 is selected, “Plumbell combination” is displayed only on the winning line L1 for the same reason as the stop link table TBL21 for replay.

  In the stop link table TBL27 for BB1 shown in FIG. 14C, even if the data group of (a) of TBL27, (b) of TBL27, or (c) of TBL27 is selected, it depends on the stop operation timing of the player. "Red 7 role" is displayed on any of the winning lines (L1 to L5).

  As described above, the stop link table stores the table number indicating the stop data table to be selected according to the operation sequence of the stop operation and the display position of the upper, middle or lower stage, the address storing the table, or the like. As an example of the stop data table group TBL31 storing a plurality of stop data tables, as shown in FIG. 15, the stop data tables TBL101 to TBL199, TBL201 to TBL299 corresponding to the reels R1 to R3 and the prizes and loses, It consists of TBL301 to TBL399. Although the stop data table group TBL31 in this embodiment is divided according to each prize or loss, it is not always necessary to make such a division, and when the same stop data table is used, the award data table group TBL31 is not necessarily divided. Even if they are different, they can be used together.

  Returning to FIG. First, the CPU 101 determines whether or not the re-game winning flag is set (S106a). If it is determined that the re-game winning flag is set, the CPU 101 selects the re-game stop link table TBL21 (S106a1) and performs this process. finish. Here, it is determined that the re-game winning flag is set when the lottery section 8 is selected or when the lottery sections 5 to 7 are selected during the SB game. When the lottery divisions 5 to 7 are selected during the SB game, any one of the BB1 winning flag, the BB2 winning flag, and the RB winning flag is set simultaneously with the re-game winning flag. In this stop link table selection process, the order of determination of the winning flag determines the priority order of which stop link table to select according to the winning flag. For example, the re-game winning flag and the BB1 winning flag are set simultaneously. If it is, the replay winning flag is given priority. Next, when it is determined that the SB winning flag is set (S106b), the SB stop link table TBL28 is selected (S106b1). Similarly, when it is determined that the RB winning flag is set (S106c), the stop link table TBL25 for RB is selected (S106c1). When it is determined that the BB2 winning flag is set (S106d), the stop link table TBL26 for BB2 is selected (S106d1). When it is determined that the BB1 winning flag is set (S106e), the stop link table TBL27 for BB1 is selected (S106e1). When it is determined that the small role C winning flag is set (S106f), the stop link table TBL22 for the small role C is selected (S106f1). If it is determined that the small role B winning flag is set (S106g), the small link B stop link table TBL23 is selected (S106g1). When it is determined that the small combination A winning flag is set (S106h), the stop link table TBL24 for the small combination A is selected (S106h1). Finally, when one winning flag is not set, the CPU 101 selects the stop link table TBL29 for losing (S106k), and ends this processing.

  As shown in FIG. 6, when each prize is classified into three types of start prize, small role prize, and replay prize, when different types of winning flags are set together (for example, BB1 prize and replay prize) ), The order of determination of the winning flags in the winning process orders which winning flag has priority. In the slot machine 1, the re-game award, the start award, and the small role award are used as the determination order. Games in which different types of winning flags are set together are a BB carryover game and an RB carryover game.

  FIG. 16 is an explanatory diagram showing a data structure of a stop data table used for stopping the right reel R3. (A) shows the symbol arrangement of the right reel band. FIGS. 16 (B), (C), and (D) show the stop data table TBL301 for replay, the stop data table TBL321 for small role B, and The stop data table TBL361 for BB1 is shown. In the slot machine 1, the middle display position is set as a reference position at the timing when the stop operation instruction signals 113a to 113c are detected, and a symbol number PN indicating the symbol position on the reel corresponding to the reference position is obtained and “stop operation symbol number” is obtained. " Here, the symbol number PN indicating the symbol position on the reel corresponding to the reference position is the middle display position that is the reference position when the reel is immediately stopped at the timing when the stop operation instruction signals 113a to 113c are detected. This means a symbol number that can be displayed on the screen. The stop data table stores the number of advance frames from “0” to “4” instructing to stop the rotation of the reel from the symbol position indicated by the acquired stop operation symbol number to the symbol position ahead. ing. “0” means stop at the symbol position indicated by the stop operation symbol number, and “4” means stop at the symbol position four frames ahead of the symbol position indicated by the stop operation symbol number. To do. As a result, it is possible to display at the middle display position with the symbol corresponding to the symbol position designated by the advance frame number as the reference position. That is, the advance frame number associated with the stop operation symbol number acquired at the timing when the stop operation instruction signals 113a to 113c are detected is obtained from the stop data table. Since the stop data table only needs to be able to indicate to which symbol position the reel is to be stopped, the symbol number PN to be stopped is stored instead of the number of advance frames such as “0” to “4”. May be.

  The replay stop data table TBL301 is stop data that can display a “plum” symbol at the middle display position regardless of the number of the stop operation symbol number acquired. The stop data table TBL 321 for the small role B is stop data that can display the “bell” symbol at the middle display position regardless of the number of the stop operation symbol number acquired. As shown in FIG. 16 (A), five “Plum” symbols and “Bell” symbols are arranged within an interval of four frames, so that “Plum” symbols and “Bell” symbols are It is a 100% retractable pattern that can be displayed at a predetermined display position.

  On the other hand, the stop data table TBL361 for BB1 can display the “red 7” symbol at the middle display position only at the five locations “3” to “7” where the acquired stop operation symbol number indicates the winning pull-in range. Stop data. When the acquired stop operation symbol number is “12” to “16”, the “white 7” symbol is displayed at the middle display position, and otherwise, the “cherry” symbol is displayed at the middle display position. .

  When the stop operation symbol number PN at the stop operation timing of the player is “7”, for example, when the stop data table TBL301 for re-game is selected, the advance frame number “3” is acquired, Advance 3 frames from the symbol position indicated by the stop operation symbol number, and display the “Plum” symbol of symbol number PN = 10 at the middle display position. When the stop data table TBL321 for the small role B is selected, the advance frame number “2” is acquired, and the “bell” symbol of symbol number PN = 9 is advanced by two frames from the symbol position indicated by the stop operation symbol number. Is displayed at the middle display position. When the stop data table TBL361 for BB1 is selected, the advance frame number “0” is acquired, and the “red 7” symbol with the symbol number PN = 7 is acquired without proceeding from the symbol position indicated by the stop operation symbol number. Display at the middle display position. Depending on the stop data table selected in this way, even when the acquired stop operation symbol numbers are the same, the symbols that stop at the middle display position are different.

<5-5: Reel stop processing>
17 to 18 are flowcharts showing the contents of the reel stop process in step S109. This reel stop process is an operation stop control process for stopping the reels according to the stop data in the stop data table group, and is stopped after the automatic stop time elapses from the reference time until the last stop reel is automatically stopped. If the stop operation is performed between the automatic stop process for controlling the reel so that it automatically stops if no operation is performed, and the automatic stop time from the reference time until the last stop of the reel is automatically stopped. It includes a stop control management process for managing stop control so that the reel is stopped by the operation stop control process. The details will be described below.

  First, the CPU 101 refers to the timer value indicating the remaining time and determines whether or not the automatic stop time has elapsed from the reference time (S109a) and whether or not the first stop button stop operation has been performed. It judges based on 113a-113c (S109b). In this example, stop button numbers “1”, “2”, and “3” are assigned to the stop buttons 13a, 13b, and 13c, respectively.

  In step S109b, when any one of the stop operation instruction signals 113a to 113c is detected, it is determined that the first stop button stop operation has been performed. In this case, a stop button number indicating the type of the stop button is acquired from the detected stop operation instruction signals 113a to 113c, and stop operation symbol numbers “1” to “3” immediately after the stop operation are acquired. Further, the stop operation symbol number is acquired at the timing when the stop operation instruction signals 113a to 113c are detected (S109c).

  On the other hand, if it is determined in step S109a that the automatic stop time has elapsed, the stop button number “3” and the symbol number of the right reel R3 at that time are acquired (S109c1), and the process proceeds to step S109d.

  Next, the CPU 101 limits the data group of the stop link table that can be used from the stop button number among the stop link tables based on the winning flag selected in the stop link table selection process of step S106 (S109d). Specifically, from the acquired stop button number, which data group from the stop link table (a) for the left reel R1, the stop link table (b) for the middle reel R2, or the stop link table (c) for the right reel R3. The use is limited.

  Next, the CPU 101 determines whether the symbol to be stopped can be displayed at any one of the upper, middle, and lower display positions. In the case of the left reel R1, the winning line L2 or L4 if it can be displayed at the upper display position, the winning line L1 if it can be displayed at the middle display position, or the winning line L3 if it can be displayed at the lower display position. L5 is a winning line candidate. In the case of the middle reel R2, the winning line L2 if it can be displayed at the upper display position, the winning line L1, L4 or L5 if it can be displayed at the middle display position, and the winning line if it can be displayed at the lower display position. L3 is a winning line candidate. In the case of the right reel R3, the winning line L2 or L5 if it can be displayed at the upper display position, the winning line L1 if it can be displayed at the middle display position, or the winning line L3 if it can be displayed at the lower display position. L4 is a winning line candidate. If display is possible at a plurality of display positions, one stop data table for a predetermined line is selected by lottery or the like from among the winning line candidates obtained by combining them (S109f).

  Next, the CPU 101 refers to the selected stop data table, acquires the advance frame number corresponding to the acquired stop operation symbol number (S109g), advances the reel that has been stopped and advances the rotation based on the frame number. To stop (S109h).

  Next, the CPU 101 refers to the timer value indicating the remaining time to determine whether or not the automatic stop time has elapsed from the reference time (S109j) and whether or not the second stop button stop operation has been performed. Determination is made based on the instruction signals 113a to 113c (S109k).

  In step S109k, when any one of the stop operation instruction signals 113a to 113c other than those already detected is detected, it is determined that the second stop button stop operation has been performed. In this case, stop button numbers “1” to “3” indicating the types of stop buttons are acquired from the detected stop operation instruction signals 113a to 113c. Further, the stop operation symbol number is acquired at the timing when the stop operation instruction signals 113a to 113c are detected (S109m).

  On the other hand, if the automatic stop time has elapsed in step S109h, the stop button number and symbol number of the rightmost reel among the remaining reels rotating at that time are acquired (S109m1). Specifically, it is determined whether the right reel R3, the middle reel R2, and the left reel R1 are rotating in this order. For example, when the middle reel R2 and the left reel R1 are rotating, the middle reel R2 is selected and stopped. The button number “2” is acquired. For example, when the right reel R3 and the middle reel R2 or the left reel R1 are rotating, the right reel R3 is selected and the stop button number “3” is acquired.

  Next, the CPU 101 determines a stop data table adapted to the display position of the already stopped reel based on the stop button number (S109p). Subsequently, the CPU 101 refers to the selected stop data table, acquires the advance frame number corresponding to the acquired stop operation symbol number (S109q), advances the reel where the stop operation is performed, and advances the rotation based on the frame number. To stop (S109r).

  Next, the CPU 101 refers to the timer value indicating the remaining time to determine whether or not the automatic stop time has elapsed from the reference time (S109s) and whether or not the third stop button stop operation has been performed. Determination is made based on the instruction signals 113a to 113c (S109t).

  In step S109t, when any one of the stop operation instruction signals 113a to 113c other than those already detected is detected, it is determined that the stop operation of the third stop button has been performed. In this case, stop button numbers “1” to “3” indicating the types of stop buttons are acquired from the detected stop operation instruction signals 113a to 113c. Further, the stop operation symbol number is acquired at the timing when the stop operation instruction signals 113a to 113c are detected (S109u).

  On the other hand, if the automatic stop time has elapsed in step S109s, the stop button number and symbol number of the remaining reels rotating at that time are acquired (S109u1). Next, it is determined whether or not the result of the internal lottery is a loss or a prize that allows 100% winning (S109z). Here, if it is determined that the internal lottery is lost or the prize is 100%, the process proceeds to step S109w.

  Next, the CPU 101 determines a stop data table adapted to the display position of the already stopped reel based on the stop button number (S109w). Subsequently, the CPU 101 refers to the selected stop data table, acquires the advance frame number corresponding to the acquired stop operation symbol number (S109x), advances the reel where the stop operation is performed, and advances the rotation based on the frame number. (S109y), and the process is terminated.

  On the other hand, if it is determined in step S109z that the internal lottery did not result in a loss and 100% winning is not possible, the CPU 101 sets an automatic stop flag to ON and specifies a reel that has not stopped ( S109z1), automatic stop processing is started (S109z2).

<5-6: Winning determination process>
FIG. 19 is a flowchart showing the contents of the winning determination process in step S110. In this winning determination process, the combination of symbols arranged on the winning line activated after the reels are stopped is checked to determine whether or not a winning combination has been established. If it is determined that a winning combination has been won and a winning combination is made, a process for starting another type of game is performed if it is a starting prize, and a payout is awarded if it is a small winning prize.

  First, the CPU 101 creates a winning determination table from stop operation symbol numbers of all reels R1 to R3 (S110a). Next, the CPU 101 performs a winning determination with reference to the winning determination table created in step S110a (S110b).

  Next, the CPU 101 determines whether or not a small role C prize has been won (S110c). If it is determined that a prize has been won, a payout process for two medals is performed (S110c1). Subsequently, it is determined whether or not the small role B prize has been won (S110d). If it is determined that the prize has been won, a payout process for 15 medals is performed (S110d1). Subsequently, it is determined whether or not a small role A prize has been won (S110e). If it is determined that a prize has been won, a payout process for 10 medals is performed (S110e1). In these payout giving processes, a payout credit process is performed in which the number of payouts is added to the credit up to the credit upper limit value (50 cards), and a payout for paying out medals from the medal payout device to the medal tray 40 for the portion exceeding the credit upper limit value. Switch to processing.

  Next, the CPU 101 determines whether or not the RB award has been won (S110f). If it is determined that the RB award has been won, the RB carryover game flag is cleared and the RB game flag is set (S110f1). Subsequently, the maximum small part winning number (remaining winning number) in the RB game is set to 8 times, and the maximum game number (remaining maximum game number) is set to 12 (S110f2).

  Next, the CPU 101 determines whether or not the BB1 award to the BB2 award has been won (S110g). If it is determined that a prize has been won, the BB carryover game flag is cleared and the BB game in-progress flag corresponding to the award is set. (S110g1) and the acquired number counter is cleared (S110g2).

  Next, the CPU 101 further sets an RB game flag (S110g3). Subsequently, the maximum number of small part winnings (remaining winnings) in the RB game is set to 8 and the maximum number of games (remaining maximum number of games) is set to 12 (S110g4). By the processing of steps S110g3 and S110g4, the RB game can be started from the first game of the BB game. If steps S110g3 to S110g4 are omitted, the RB game is not executed immediately after the start of the BB game, the BB base game is executed as shown in FIG. It can be a BB game to be started.

  Next, the CPU 101 determines whether or not the SB prize has been won (S110h). If it is determined that the SB prize has been won, the SB game in-progress flag is set (S110h1), and the maximum number of games (remaining maximum number of games) is set. Set once (S110h2). Further, since the “SB role” of the SB award is the start condition of the RT period, the RT period flag is set, and the RT count is set to 5 games (S110h3). That is, by winning the SB award, the SB game for one game is started and the RT period for five games is started.

<5-7: Winning flag clear process>
FIG. 20 is a flowchart showing the contents of the winning flag clear process in step S112. In this winning flag clearing process, the winning flag set by internal lottery or the like during one game is cleared at the end of one game based on the type of winning flag and the result of the game, or carried over to the next game without being cleared. Do things.

  First, the CPU 101 clears each winning flag in one game regardless of the winning of the replay winning flag, the SB winning flag, the small role A winning flag, the small role B winning flag and the small role C winning flag (S112a).

  Next, the CPU 101 determines whether or not the BB1 winning flag is set (S112b). If it is determined that the flag is set, the CPU 101 further determines whether or not the BB1 prize is won (S112c). If it is determined that “Red 7 role” has been established and the prize has been won, the BB1 winning flag is cleared (S112d). If it is determined in step S112c that no winning is made, the BB carryover game flag is set (S112e), and the BB carryover game is set from the next game.

  Next, the CPU 101 determines whether or not the BB2 winning flag is set (S112f). If it is determined that the flag is set, the CPU 101 further determines whether or not a BB2 prize has been won (S112g). If it is determined that “White 7 role” has been established and won, the BB2 winning flag is cleared (S112h). If it is determined in step S112g that no winning has been made, the BB carryover game flag is set (S112j), and the BB carryover game is set from the next game.

  Next, the CPU 101 determines whether or not the RB winning flag is set (S112k). If it is determined that the flag is set, the CPU 101 further determines whether or not the RB prize is won (S112m). When it is determined that “BAR combination” has been established and the prize is won, the RB winning flag is cleared (S112n). If it is determined in step S112m that no winning has been made, the RB carryover game flag is set (S112p), the next game is changed to the RB carryover game, and the process is terminated.

<5-8: Production>
In the above-described embodiment, in relation to the SB prize, the CPU 101 starts 1 game SB game by 1) establishment of a “Plumbell role” to be won. 2) The RT period of 5 games is started when the winning “Plumbell role” is established. 3) The SB prize is a single bet game that is not executed during the normal game, and the winning probability of a special game start prize (BB prize, RB prize, etc.) is high. 4) An internal lottery is executed so that the winning flag for the special game start prize (BB prize, RB prize, etc.) is set simultaneously with the re-game prize. Then, when winning the SB prize, the RT period extending from the SB game to 5 games is started, and in the SB game, the re-game prize is won alone or at the same time as the special game start prize. Therefore, in the SB game, the regame prize is easy to win. The re-game award is easy to win because the “replay role” for the re-game award is a 100% winning design and is not affected by the player's operation timing, and when the special game start award is won. This is because even if there is, stop control giving priority to replaying is executed. For a player who won a replay award in an SB game, it is unclear whether he or she won the replay award alone or at the same time as the special game start award. Can be expected. Moreover, in the RT period that continues after the SB game, the re-game prize is continuously won, so there is little or no chance to win the special game start prize even if it is a carryover game. Therefore, during the RT period of 5 games including the SB game, it is possible to effectively realize the effect of encouraging the player's expectation. In the present embodiment, effects using the liquid crystal display 30 are executed in five games in the RT period. The effect performed during the RT period is also called a continuous effect with respect to the normal effect.

  FIG. 21 is a diagram showing the contents of a continuous effect executed by the CPU 191 of the display control board 100B during the RT period. Note that the notification data for production is stored in the ROM 194. The CPU 191 of the display control board 100B determines the content of the presentation (notification instruction information) based on the winning information received from the CPU 101 and the RT count. Specifically, when the winning information indicates winning of both the re-game prize and the BB prize, “pattern A” (first notification data) is selected as the display pattern. When this “pattern A” is selected, the RT count is “5” in the SB game, so the contents of “effect a” are displayed on the screen. Subsequently, in the BB carryover game RT period, “effect b” → “effect c” → “effect d1” → “effect e1” is displayed on the screen for each game according to the RT count. On the other hand, when the winning information indicates winning of both the re-game prize and the RB prize, “pattern B” is selected as the display pattern. When this “pattern B” is selected, the RT count is “5” in the SB game, and therefore the contents of “effect a” are displayed on the screen. Subsequently, in the RB carryover game RT period, “effect b” → “effect c” → “effect d1” → “effect e2” is displayed on the screen for each game in accordance with the RT count. Further, when the winning information indicates only the re-game prize, “pattern C” (second notification data) is selected as the display pattern. When this “pattern C” is selected, the RT count number indicates “5” in the SB game, so the contents of “effect a” are displayed on the screen. Subsequently, in the normal game RT period, “effect b” → “effect c” → “effect d2” → “effect e3” is displayed on the screen for each game according to the RT count. As described above, when the RT count number indicates 5, the content of the same “effect a” is displayed on the screen regardless of the display pattern. Similarly, when the RT count number is 4 to 3, the same contents of “effect b” to “effect c” are displayed on the screen. When the RT count number is 2, “effect d1” is displayed on the screen for each game in “pattern A” and “pattern B”, and “effect d2” is displayed on the screen for each game in “pattern C”. To do. When the RT count number is 1, “effect e1”, “effect e2”, or “effect e3”, which are different contents of the “pattern A”, “pattern B”, and “pattern c”, respectively, are played in the game. Display on the screen every time. That is, “pattern A” and “pattern B” display the same effect content with an RT count of 5 to 2, and “pattern A” or “pattern B” and “pattern C” have an RT count of 5. The same effect content is displayed up to ~ 3. Therefore, the player starts the SB game and displays a series of effect contents over a plurality of games on the liquid crystal display 30. However, if the RT period does not elapse for 4 games (RT count = 2), the player will receive the BB award or the RB award. It is unclear whether they are winning. Furthermore, if the game is not the last game in the RT period (RT count = 1), it is unknown whether the BB prize or the RB prize is won. Therefore, it is possible to give the player a sense of expectation that may have won the BB prize in this RT period over several games.

  “Pattern A” to “Pattern C” in the above description are associated with effects for five games corresponding to the RT count number. For example, in “Pattern C”, the RT count number is “5”. It is also possible to associate the effects to be displayed only when they are shown and return to the normal effects without displaying the continuous effects in the remaining games (RT count = 4 to 1). That is, the pattern includes a continuous effect that is a set of effects over five games and a single effect that ends in one game. In addition, the pattern may include a set of effects that end when the RT count is “2” to “4”.

  As described above, in the present embodiment, pattern A data (first notification data) and pattern C data (second notification data) indicating notification contents are stored in the ROM 194, and the winning information indicates the BB prize. In this case, pattern A data (first notification data) is read from the ROM 194, and notification is executed according to the read pattern A data (first notification data). On the other hand, when the winning information does not indicate the BB prize, the pattern C data (second notification data) is read from the ROM 194, and notification is executed according to the read pattern C data (second notification data). Then, in both cases of the notification of the pattern A and the notification of the pattern B, the notification is started upon the start of the RT period, that is, the start of the SB game.

  In this case, “true” notification of pattern A and “false” notification of pattern C can be started from a common opportunity. Since the start of the notification is set based on the winning of the SB game start prize, that is, the start of the SB game, it is not necessary to determine when to notify “false” by lottery or the like, thereby reducing the processing load. It becomes possible. Since the processing load can be reduced if the opportunity is common, it is not necessary to immediately start the notification from the start of the SB game, and it may be started after a predetermined number of games have elapsed.

<2. Summary>
FIG. 22 shows an outline of the above-described embodiment. In the slot machine 1, a lottery of the SB prize which is a specific game start prize in the normal game (a) is executed. When the lottery is won and the SB prize is won, the next game shifts to the SB game (b) as a specific game and the RT period (high probability period) starts. In the SB game, the probability that the special category is selected by the internal lottery is higher than that in the normal game. In this example, it is about 130 times. The special category of the SB game is assigned with a special game start prize BB prize and replay prize. Therefore, most of the BB prize winnings are when the special category is selected in the SB game. In addition, the probability that the replay category is selected by the internal lottery during the RT period is higher than that in the normal game. For this reason, the probability of winning the re-game prize also increases in the SB game that is a part of the RT period. Further, during the RT period, the CPU 101 executes reel stop control so that the re-game award is given priority over the BB prize. Specifically, when the winning flag as the lottery information indicates both the BB prize and the re-game prize, the symbols constituting the BB prize and the re-game prize are configured at the timing when each of the reel stop buttons 13a to 13c is operated. When the symbol to be played is within the drawing range from the winning line and there is a possibility of winning the replay prize, each of the reels R1 to R3 is controlled so that the symbols constituting the replay prize are stopped on the winning line. To do. If the symbols are stopped at a position where there is no possibility of winning the replay prize due to the first stop and the second stop, it is not always necessary to draw the symbols constituting the replay prize on the winning line. . However, when the re-game prize is composed of 100% winning symbols as in this embodiment, the re-game prize is always won.

  Here, if the re-game award is composed of 100% winning symbols, in the SB game, if the re-game award is won, the player can detect the possibility of winning the BB award. Further, since the SB game, which is the first game in the RT period, is produced, the player plays the RT period game with a sense of expectation that the player may have won the BB prize. When the special category is selected by lottery in the SB game, the game shifts to the carry-over game (c1) during the RT period. In this period, the probability that the re-game division is selected by the internal lottery is higher than that of the mere carry-over game (c). Therefore, the re-game prize is won in most of the carry-over games (c1) during the RT period. As described above, since the reel stop control is executed so that the re-game award is given priority over the BB award, it is rare to win the BB award in the carryover game (c1). That is, the BB prize is won only when the re-game prize is not won in the internal lottery and the player operates the reel stop buttons 13a to 13c in a timely manner so that the BB prize is won. Therefore, in the RT period, the player can be notified of the possibility of winning the BB prize, and the difficulty of winning the BB prize can be increased. As a result, the player expects to win the BB prize while watching the effect screen.

  On the other hand, when the BB prize is not won in the SB game, the routine shifts to the RT period (a1) of the normal game. Even during the period (a1), the probability that the re-game division will be selected by the internal lottery is high, so that the player can be expected to win the BB prize.

  When the RT period ends and the game shifts to the carry-over game (c), the probability that the re-game category is selected by lottery decreases, so the probability that the re-game award is not selected increases and the re-game award is BB. Decreasing winnings in preference to awards is reduced. As a result, it becomes easy to win the BB prize. If the BB game is not won in the SB game, the RT period ends and the game moves to the normal game (a).

  Thus, in the present embodiment, the RT period is started from the SB game on condition that the SB prize is won. In the first game in the RT period, the winning probability of the BB prize is set to be high. In other words, instead of starting the RT period on the condition that the BB prize is won, the SB prize winning condition, which is the starting condition of the SB game having a high probability of winning the BB prize, is set as the transition condition to the RT period. . If the BB prize is won in the SB game, the RT period functions as a true effect period, whereas if the BB prize is not selected in the SB game, the RT period functions as a false effect period. As a result, it is not necessary to perform a special lottery in order to provide a false performance period. Also, it is not necessary to manage two types of RT periods. As a result, it is possible to greatly reduce the processing load related to the lottery process and the management of the RT period.

<3. Modification>
The present invention is not limited to the above-described embodiment, and for example, the following modifications are possible.
(1) In the above-described embodiment, in the SB game as the specific game, both the BB prize and the replay prize are assigned to the special category, but the present invention is not limited to this, for example, FIG. As shown in A), only the BB prize may be assigned to the special category. Further, as shown in FIG. 23B, in the SB game, both the BB prize and the small role prize may be assigned to the special category. In the SB game, the lottery for the small role prize is executed in the same manner as in the normal game. When winning the small role award in the SB game, if the small role award and the BB award are assigned to the special category, it can be unclear whether or not the BB award has been won. On the other hand, if the small role prize is not assigned to the special category, the player is informed that the BB prize is not selected. According to the modified example, since both the BB prize and the small part prize are assigned to the special category, even if the small part prize is won in the SB game, the game expects that the BB prize is won in the RT period. Can be held by a person.

(2) Further, the above-described slot machines include not only medals but also those that can execute a game by inserting pachinko balls. In this case, the pachinko balls stored in the tray are taken into the slot machine by operating the bet button 11. When five pachinko balls are taken in, the winning line indicator 21 corresponding to the winning line L1 lights up, and when ten pachinko balls are taken in, the winning line indicator 21 corresponding to the winning lines L2 and L3 in addition to the winning line L1 is displayed. Is turned on, and when 15 pachinko balls are taken in, the winning line indicators 21 corresponding to the winning lines L4 and L5 may be turned on in addition to the winning lines L1 to L3. In this way, in the case of a pachinko ball, it is not necessary to perform an operation for a player to directly hold it by hand and insert it into the slot machine's medal slot.
