Description

  The present invention relates to a slot machine.

  The slot machine generally includes three reels, a display window provided on the front surface of each reel, three reel stop buttons corresponding to each reel, and a start lever for starting a game. A plurality of symbols are arranged on each reel, and an area where one symbol is arranged is called a frame. In the display window, three symbols stop at symbol stop positions such as an upper stage, a middle stage, and a lower stage. A set of symbol stop positions of each display window is a winning position. Generally, the position of the winning position is as follows: the middle of each display window, the top of each display window, the bottom of each display window, the top of the left display window, the middle of the middle display window, the bottom of the right display window, the left display window There are the lower and middle display windows, the middle and right display windows, and each winning position is called a winning line.

  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 to determine which prize is won or lost, and internal lottery information indicating the lottery result is generated.

  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 operation timing is delayed. Then, the reel is controlled so that the symbols constituting the combination do not stop on the effective 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 which is an internal lottery is won, the drawing control is performed so that the symbols constituting the combination corresponding to the prize stop on the winning line even if the operation timing of the reel stop button is slightly early. The number of frames that are advanced from the operation of the reel stop button until the reel moves and stops is limited to a maximum of four frames. The display window can stop three symbols at symbol stop positions such as an upper stage, a middle stage, and a lower stage. For this reason, the range in which a predetermined symbol can be stopped in the display window is seven frames. Here, if the operation timing of the reel stop button is greatly deviated, no prize is won. In other words, in order for a player to win a prize, it is necessary to win a prize by an internal lottery and align the winning combination on an effective prize line.

The multiple awards include a start prize for switching the game state from the normal game to another game, a small role prize that gives a predetermined number of medals as a dividend, and a condition for starting the next game without inserting medals. Includes replay prizes to be awarded. In addition, there is known a slot machine capable of executing a replay time game (hereinafter referred to as an RT game) in which a winning probability of an internal lottery replay prize is high as a game state compared to a normal game. In such a slot machine, the transition from the normal game to the RT game is often made on condition that a lottery different from the internal lottery is executed and the lottery is won. For example, Patent Document 1 includes a special game storage mode for storing a right to perform a big bonus, and a special game release mode for providing a player with a special game for the number of times of the stored right. There are a plurality of special game release mode transition lottery determination means for determining whether or not to shift to the special game release mode in each mode, and whether or not to shift to any other special game storage mode by lottery. There is disclosed a slot machine provided with other special game storage mode transition lottery determination means for determining.

However, in the conventional slot machine, since the lottery for mode transition is executed independently of the internal lottery, two lottery processes such as the internal lottery and the mode transition are required, and the processing is complicated. It was.
Since the transition of the mode is not associated with the outcome that is a sequence of symbols in a state where each reel is stopped, the player cannot know which mode the current game is in.

  The present invention has been made in view of the above-described problems, and allows the transition to the RT game without increasing the processing, and allows the player to know in which mode the game is played. The problem to be solved is to provide a machine.

  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.

  The slot machine according to the present invention is for a player to input a plurality of display rows (R1, R2, R3) each having a plurality of kinds of symbols arranged therein and capable of variable display, and an instruction to start the variable display. Start operation means (12), and stop operation means (13a, 13b, 13c) for a player to input an instruction to stop the variable display, the plurality of display rows (R1, R2, R3) When the stop mode on the pay line (L1 to L5) in the state where the variable display is stopped is a predetermined mode, a prize is awarded, and a predetermined game value is given according to the prize awarded. The first re-game award and the first re-game award for giving a condition for starting the next game without paying the game medium as the game value to be given as the game value to be given, and the game value to be given as the game value to be given. 2 Replay Award And can execute a plurality of types of games including a base game, a first probability variation game (RT1), and a second probability variation game (RT2), and one of the lottery targets is selected. The lottery information indicating the lottery result is generated and the first replay is performed on the lottery targets of the base game, the first probability variation game (RT1), and the second probability variation game (RT2). A plurality of re-game awards including a game award and the second re-game award, and a small role award. The first probability variation game (RT1) and the second probability variation game (RT2) Each of the game prizes is set such that a combined probability obtained by totaling the winning probabilities selected in the lottery is different from that of the normal game, and the first probability varying game (RT1) and the second probability varying game ( RT2) In the base game, the lottery means (101, S104 to S105) for setting the winning probabilities that the first regame prize and the second regame prize are selected in the lottery are different from each other. Detecting that the first re-game award is won, detecting that the game type is transferred from the next game to the first probability variation game (RT1), and that the second re-game award is won Then, the game type is transferred from the next game to the second probability variation game (RT2), and the first number of games is managed by managing the number of games from the start in the first probability variation game (RT1). When the game type is reached, the game type is changed from the next game to the normal game, and when it is detected that the first replay prize is won, the first probability variation game (RT1) is continued, Won the 2nd Regame Award When the game is detected, the game type is transferred from the next game to the second probability variation game (RT2), and in the second probability variation game (RT2), the number of games is managed from the start and the second When the number of games reaches 2, the game type is transferred from the next game to the normal game, and when it is detected that the second replay prize is won, the second probability variation game (RT2) is continued. When it is detected that the first replay prize has been won, game management means (101, S110b, S110b1 to S110b5) for transferring the game type from the next game to the first probability variation game (RT1). S110c, S110c1 to S110c5).

  According to the present invention, it is possible to execute the first and second probability variation games in which the combined probability of the replay prize is different from that of the base game. The transition to the first probability-changing game is conditional on winning the first re-game prize, and the transition to the second probability-changing game is conditional on winning the second re-game prize. Therefore, it is not necessary to execute the lottery for transferring the game type separately from the internal lottery, so that the process becomes simple. In addition, winning is a condition for shifting, and winning in the first re-playing award and second re-playing award is that the symbols constituting the award are arranged on the winning line. It can be clearly known that the game is shifted to the first or second probability variation game. Furthermore, since the winning probabilities of the first replay prize and the second replay prize can be set independently for the first probability varying game and the second probability varying game, the transition probability between the probability varying games Can be set freely, and the taste of the game can be improved.

  Further, in the first and second probability variation games, the first and second replay prizes can be drawn and the same game can be continued on the condition of winning. Here, when the game management means (101, S110b, S110b1 to S110b5, S110c, S110c1 to S110c5) wins the first replay prize in the first probability variation game (RT1), The probability variation game (RT1) is continued, but as a way to continue, the number of games obtained by adding the first number of games to the number of remaining games until the first number of games is reached in the game The number of games may be set as one, the number of games from the start of the first probability variation game (RT1) may be reset, or the number of games may be set before the first number of games is reached. The count may be maintained as it is. Similarly, when the game management means (101, S110b, S110b1 to S110b5, S110c, S110c1 to S110c5) wins the second replay prize in the second probability variation game (RT2), The second probability variation game (RT2) is continued. As a way to continue, the number of games obtained by adding the second number of games to the number of remaining games until the second number of games is reached in the game. The number of games may be set as the second number of games, the number of games from the start of the second probability variation game (RT2) may be reset, or the game may be played before the second number of games is reached. The count of numbers may be maintained as it is.

  In the slot machine described above, the lottery means (101, S104 to S105) is configured such that the winning probability of the second re-game prize is the winning probability of the first re-game prize in the first probability variation game (RT1). It is preferable that the winning probability of the second re-game prize is set to be larger than the winning probability of the first re-game prize in the second probability variation game (RT2). . In this case, in the first probability variation game, the winning probability of the first replay prize is larger than the winning probability of the second replay prize, so the game type is changed to the first probability varying game again. The possibility of continuing the same type of game can be increased. On the other hand, in the second probability variation game, the winning probability of the second replay award is larger than the winning probability of the first replay award, so that the game type is changed to the first probability varying game and the game The possibility of changing the type can be increased. Thereby, as a game state, the 1st probability variation game with high continuity and the 2nd probability variation game with low continuity can be produced, and the game preference can be improved.

  In the slot machine described above, the game management means (101, S110b, S110b1 to S110b5, S110c, S110c1 to S110c5) is configured such that the first replay prize and the first replay prize in the first probability variation game (RT1). When the total of the winning probabilities of the second replay prize is the first synthetic probability, the first game number is set larger than the reciprocal of the first synthetic probability, and the second probability variation game (RT2) The second game number may be set to be larger than the reciprocal of the second synthesis probability when the total probability of winning the first replay prize and the second replay prize is the second synthesis probability. preferable. According to the present invention, in the first and second probability variation games, when the first and second game numbers have elapsed, the game state is shifted to the normal game, but the first game probability is more than the reciprocal of the first synthetic probability. Since the number of games is large and the second game number is larger than the reciprocal of the second synthetic probability, the probability variation rather than the possibility of returning to the normal game when moving from the normal game to the first or second probability variation game The possibility of continuing the game can be increased.

  In the slot machine according to the present invention, a player inputs a plurality of display rows (R1, R2, R3) each having a plurality of kinds of symbols arranged therein and capable of variable display, and an instruction to start the variable display. Start operation means (12) for stopping and a stop operation means (13a, 13b, 13c) for a player to input an instruction to stop the variable display, and the plurality of display rows (R1, R2, R3) ) In the state in which the variable display of) is stopped, when the stop mode on the pay line (L1 to L5) is a predetermined mode, a prize is awarded, and a predetermined game value is given according to the prize awarded, The first re-game award for granting a condition for starting the next game without paying the game medium as the game value to be given is given as a small role award with payout of game media as the game value to be given. And second re A lottery information that includes a technical award and can execute a plurality of types of games including a base game and a probability variation game, and executes a lottery for selecting one of the lottery targets and indicates a lottery result. A plurality of re-game awards including the first re-game award and the second re-game award and a small role award are generated as the lottery targets of the base game and the probability-variable game; Each of the re-game prizes is set so that the combined probability of the winning probabilities selected in the lottery is higher than that of the normal game, and the first replay prize is set between the normal game and the probability varying game. In the base game, the lottery means (101, S104 to S105) for setting the game prize and the second replay prize to be different so that the winning probabilities selected in the lottery are different from each other. In When it is detected that the game has been won, the game type is transferred from the next game to the probability variation game. In the probability variation game, when the game number is managed from the start and the predetermined game number is reached, the next game The game management means (101, S110b, S110b1 to S110b5, S110c, S110c1 to S110c5) that continues the probability varying game when it is detected that the game type is transferred to the normal game and the second replay prize is won. ).

  According to the present invention, it is possible to execute a probability variation game in which the composite probability of the replay prize is different from that of the normal game. Transition to the probability-changing game is conditional on winning the second replay prize. Therefore, it is not necessary to execute the lottery for transferring the game type separately from the internal lottery, so that the process becomes simple. In addition, winning is a condition for shifting, and winning in the second re-playing award is that the symbols that make up the award are on the winning line, so the player moves from the next winning game to a stochastic game. To know clearly what to do.

  In the slot machine described above, the lottery means (101, S104 to S105) is set so that the winning probability of the second replay prize is higher than the winning probability of the first replay prize in the probability variation game. It is preferable to do. In this case, it is possible to increase the possibility of continuing the probability variation game by winning the second replay prize. Here, when the sum of the winning probabilities of the first re-game prize and the second re-game prize in the probability variation game is a composite probability, the predetermined number of games is set larger than the reciprocal of the composite probability. Alternatively, the predetermined number of games may be set larger than the reciprocal of the winning probability of the second replay prize in the probability variation game.

  In the slot machine described above, when the game management means (101, S110b, S110b1 to S110b5, S110c, S110c1 to S110c5) detects that the first replay prize has been won in the probability variation game, It is preferable to shift the game type from the game to the normal game. In this case, in the probability variation game, it is possible to draw a first replay award that falls into the base game and a second replay award that continues the probability variation game.

  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. On the left, middle and right reels, 21 symbols are printed at equal intervals. Since stepping motors 54a to 54c that rotate once by supplying a pulse of 400 steps are used, when 21 symbols are arranged, the interval of symbols becomes 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 the process proceeds 29 steps after detecting ~ 155c, the symbol number PN = 2 is positioned on the winning line L1, and if the step 48 is advanced, the symbol number PN = 3 is positioned on the winning line L1, and if the step is advanced 390 steps 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. Accordingly, a predetermined symbol can be positioned on the winning line L1 by the number of steps to be advanced with the timing at which the reel position detection signals 155a to 155c are detected as a base point. The symbol arrangement on the reel band is stored as symbol code PC data such as “01” for red 7 symbols and “07” for blue plum symbols as described in parentheses in FIG. Has been.

<4-2: Slot machine awards and roles>
FIG. 6 is an explanatory diagram for explaining the prizes and combinations in the slot machine 1 and shows the configuration of the types of awards and their combinations (combination of symbols). In the slot machine 1, a prize is awarded when a predetermined symbol combination is aligned on the activated prize line, and a small prize is awarded with a maximum of 15 medals based on the number of prizes determined by the combination. There are also prizes for starting other types of games from regular games.

  As a prize for starting another type of game, a BB1 award consisting of a combination of symbols “red 7-red 7-red 7” (also referred to as a BB1 role) for starting a BB1 game, and “white 7- for starting a BB2 game” There is a BB2 award consisting of a combination of symbols “White 7-White 7” (also referred to as a BB2 role) and an RB award consisting of a combination of symbols “BAR-BAR-BAR” (also referred to as an RB role) for starting an RB game. Each content of the BB1 game and the BB2 game can be arbitrarily set as long as the definition of the BB game is followed. In addition, the BB1 game and the BB2 game may be games with different winning roles for the small role prize, may be games with different numbers of medals as end conditions, or may be the same game. . Hereinafter, when it is not necessary to distinguish between BB1 and BB2, they are collectively referred to simply as BB.

  As a small role award for giving a dividend, a small role A prize consisting of a combination of “watermelon-watermelon-watermelon” symbols (also called a watermelon role) with 15 medals as a dividend, and 10 medals as a dividend “ Belle-Bell-Belle "combination of symbols (also referred to as a bell) B Small Award B, consisting of a combination of" Cherry-ANY-ANY "symbols (also referred to as a cherry) with two medals as dividends There is a small role C prize. ANY may be any symbol. This cherry role is a win when the cherry symbols of the left reel R1 are aligned on the winning line. When the cherry symbols are displayed in the middle stage of the left reel R1 (position of the winning line L1), the winning line L1 is displayed. Although it is a win, when it is displayed on the upper stage of the left reel R1, it is a win on the pay lines L2 and L4. Simultaneous winning on a plurality of winning lines is called duplicate winning. In this case, four payouts can be obtained.

  In addition, a re-game 1 award consisting of a combination of symbols of “blue plum-blue plum-blue plum” (also called blue plum), which plays the next game without a betting operation (no game medal inserted) and “blue plum” There is a second replay award consisting of a combination of “Blue Plum-White Plum” (also called white plum). When winning the replay 1 award, the normal game RT1 (replay winning high probability game) in which the lottery probability of the replay 1 award or the replay 2 award among a plurality of awards from the next normal game is changed to 100 games. Giving across. When winning the replay 2 prize, the normal game RT2 (replay winning high probability game) in which the lottery probability of the replay 1 award or the replay 2 award among the plurality of awards from the next normal game is changed to 10 games. Giving across. Although not shown in the present embodiment, either a blue plum or a white plum may be provided as a replay prize for playing a game without a betting operation only for the next game, or another role (for example, a red plum role, etc.) may be provided for the next game. Only a replay prize for playing a game without a betting operation may be provided.

<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.
(1) Start and end of the BB game In FIG. 7A, the slot machine 1 wins the BB prize by the internal lottery during the normal game, and when the BB role is established and the prize is won, the BB game starts from the next game. Is done. The BB game is ended when the acquired number of sheets in the BB game exceeds the specified number.
(2) BB inside game Even if the BB prize is won in the internal lottery during the normal game, if the BB role is not established, the BB prize winning flag will be carried over until the next game is won. Become. When the BB combination is established in the BB1 internal game and a prize is won, the BB game is started from the next game.
(3) Start and end of the RB game When the RB prize is won by the internal lottery during the normal game and the RB combination is established and won, the RB game is started from the next game. A maximum of 12 RB games are played, and when the RB game is won eight times, the RB game is terminated.
(4) RB inside game When the RB prize is won by an internal lottery during a normal game, if the RB role is not established, the winning flag of the RB prize is carried over until the next game is won and Become. When an RB combination is established and won in the RB inside game, the RB game is started from the next game.
(6) Normal game RT1
When the replay 1 prize is won during the normal game, RT (replay winning high probability game) with the upper limit of 100 games is started from the next game. As shown in FIG. 7A, when the internal game, the BB game, or the normal game RT2 is started during the normal game RT1, the normal game RT1 ends. As shown in FIG. 7B, during the normal game RT1, the winning probability of the replay 1 prize is 1 / 6.2, the winning probability of the replay 2 prize is 1 / 163.8 and the replay 2 prize is won. Therefore, the continuation probability of continuing the normal game RT1 after winning the replay 1 prize is higher than the transition probability of shifting to the normal game RT2. The synthesis probability of the re-game award in the normal game RT1 (the sum of the lottery probabilities of the re-game 1 and 2 awards) is 1 / 6.0, which is higher than the synthesis probability 1 / 7.3 of the re-game award in the normal game It is set high. As described above, during the normal game RT1, one of the six games is won at any one of the re-game prizes, and the re-game prize is won regardless of the stop operation timing of the player. Therefore, the normal game RT1 is continued or shifted to the normal game RT2, so that the normal game is not returned. Furthermore, since the continuation rate of the normal game RT1 is increased, the game is mostly advanced in the normal game RT1.

(7) Normal game RT2
When the second replay prize is won during the normal game, ten games RT (replay winning high probability game) is started from the next game. As shown in FIG. 7A, when the internal game, the BB game, or the normal game RT1 is started during the normal game RT2, the normal game RT1 ends. As shown in FIG. 7B, during the normal game RT2, the winning probability of the replay 1 award is 1 / 163.8, the winning probability of the replay 2 award is 1 / 3.0, and the replay 1 award is won. Thus, the continuation probability of continuing the base game RT2 after winning the replay 2 prize is higher than the transition probability of transitioning to the base game RT1. The composite probability of the re-game prize in the normal game RT2 (sum of the lottery probabilities of the re-game 1-2 prizes) is 1 / 2.9, and the composite probability of the re-game prize in the normal game and the normal game RT1 is 1 / 2.9. It is set higher than 7.3 and 1 / 6.0. As described above, during the normal game RT2, one of the three games is won at one of the regame prizes, and in the regame prize, the game is won regardless of the stop operation timing of the player. Therefore, since the normal game RT2 is continued or shifted to the normal game RT1, the normal game is not returned. Furthermore, since the continuation rate of the normal game RT2 is increased, once the normal game RT2 is reached, the game is almost advanced in the normal game RT2. Therefore, this state continues until the BB game or the RB game is started.

(8) 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 and 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 lottery 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 and won, the RB game (RB game during BB) is started from the next game, and when the RB game is won eight times during the RB game, the RB game is ended. . 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.

<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, based on the medal insertion signal 160 or the bet operation instruction signals 111a to 111c, the CPU 101 determines 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. Wait until it is detected (S100). When the signal is detected, the process proceeds to the next, and it is determined whether or not the start lever operation has been performed based on the start operation instruction signal 112, and waits until the signal is detected (S101). When the signal is detected, the betting operation is prohibited (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 makes it a random value. (S103). Next, referring to the game type data, a prize lottery table corresponding to the type of the game is selected (S104). Although details will be described later, the prize lottery table is determined according to the bit status of the game type data. Using the selected prize lottery table, it is determined which numerical range set for each prize on the prize lottery table the acquired random number value belongs to, and a winning flag for the prize is set (S105). . 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. 13).

  In this embodiment, since the minimum consumption time of one game is 4.1 seconds, the timer value that counts down to 0 every 2 milliseconds indicating the elapsed time of one game is referred to until the timer value reaches 0. Wait (S107). When the timer value reaches 0 to start rotation of the reel as a starting point for measuring the elapsed time of one game, the timer value is set to an initial value (2050) corresponding to 4.1 seconds, and three reels To drive the reel drive signals 154a to 154c to rotate the stepping motor simultaneously or sequentially (S108). Specifically, the reel drive signals 154a to 154c include a plurality of drive signal lines for exciting a plurality of winding phases, and the reels are supplied by supplying a pulse signal to each drive signal line in a predetermined phase pattern. Rotate. Also, even if the start lever is operated in step S101, if 4.1 seconds have not elapsed since the start of rotation of the reel of the previous game, the reels R1 to R3 immediately enter a standby state without rotating and enter a standby state. Inform the player of this by a lamp or sound.

  Next, the CPU 101 detects that the three reels R1 to R3 have reached a constant rotational speed after all the three reels R1 to R3 have reached a constant rotational speed through an acceleration period of 10 steps. Is used as a reference time, and measurement of the remaining time from the reference time until the automatic stop time elapses is started, and an LED incorporated in the stop button is lit to notify that the stop buttons 13a to 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 of detecting that the three reels R1 to R3 have reached a constant rotation speed, after a predetermined number of steps have elapsed from the start of rotation, or after a predetermined time has elapsed from the start of rotation (a predetermined number of interruptions have occurred), A method of assuming that a constant rotational speed has been reached by outputting pulses at regular intervals to the stepping motor, or after a predetermined number of steps have elapsed since the start of rotation, or after a predetermined time has elapsed since the start of rotation (a predetermined number of interruptions have occurred) There is a method of determining that a predetermined rotational 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. 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, the position of the stop button operation based on the stop link table selected in step S106. The symbol number PN to be stopped is determined from the stop data in the stop data table group, the braking force is applied by all-phase excitation that simultaneously excites all winding phases, and the equivalent of 15 steps after starting all-phase excitation. Reel stop processing to rotate and stop due to inertia is performed for each reel, and when the automatic stop time has elapsed from the reference time (remaining time is exhausted), the reel that has not been stopped is automatically stopped. Let

  Next, when all reels are stopped, the CPU 101 determines whether or not a winning combination is established on a valid winning line (S110), and if winning, a game value set for each winning combination is given. To do. Next, a game end determination process is performed (S111), and then 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 part prize that the flag cannot carry over, the winning flag is cleared regardless of winning or missing. Subsequently, the prohibition of the bet operation performed in step S102 is canceled (S113), so that the insertion of a game medal or the input of the bet button 11 can be performed, and the process returns to step S100 to prepare for the start of the next game.

<5-2: Prize lottery table determination process>
FIG. 9 is an explanatory diagram showing an example of lottery using the prize lottery table selected in the prize lottery table determination process in step S104. During a regular game, a small role C prize, a small role B prize, a small role A prize, an RB prize, a BB2 prize, a BB1 prize, a replay 2 prize, a replay 1 prize, or a loss is determined by lottery. The lottery probabilities are “200/16384”, “910/16384”, “300/16384”, “200/16384”, “75/16384”, “75/16384”, “10/16384”, “2240/16384”, respectively. ”And“ 12374/16384 ”, a lottery is performed using the prize lottery table TBL11 in which data indicating the lottery probability is stored, and a winning flag of the winning prize is set.

  In the prize lottery table TBL11, the lottery classification data “200” of the small role C prize is stored in the first memory 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 199. The case indicates that the small role C prize has been won. In the storage area offset 02H from the top of the prize lottery table, the lottery B prize lottery classification data “910” is stored, and if the obtained random number value is in the range of 200 to 1109, the prize is assigned to the small role B prize. Shows that you have won. In the storage area offset by 04H from the top of the prize lottery table, the lottery A prize lottery classification data “300” is stored, and if the obtained random number value falls within the range of 1110 to 1409, the prize is assigned to the small role A prize. Shows that you have won. The storage area offset by 06H from the top of the prize lottery table stores the RB prize lottery classification data “200”. If the obtained random number value is in the range of 1410 to 1609, it means that the RB prize is won. Show. The storage area offset by 08H from the beginning of the prize lottery table stores the lottery classification data “75” for the BB2 prize. If it belongs to the range of 1610 to 1684, it indicates that the BB2 prize is won. In the storage area offset by 0 AH from the top of the prize lottery table, the lottery classification data “75” of the BB1 prize is stored, and if the acquired random number value belongs to the range of 1685 to 1759, it means that the BB1 prize is won. Show. The re-game 2 award lottery classification data “10” is stored in the storage area offset by 0 CH from the head of the award lottery table. If it belongs to the range of 1760 to 1769, it indicates that the re-game 2 award is won. . In the storage area offset by 0EH from the beginning of the prize lottery table, lottery classification data “2240” of the replay 1 prize is stored, and if the acquired random number value belongs to the range of 1770 to 4009, it is determined as the replay 1 prize. Shows that you have won. In addition, the data of the numerical value range belonging to the lose is not stored, the acquired random number value is sequentially compared with the lottery classification data from the small role C prize to the replay 1 prize, and it is determined that it does not belong to any range If you are lost. The prize lottery tables TBL12 to 17 described later are the same as the prize lottery table TBL11 except that the prizes to be drawn and the range of numerical values are different.

  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, and FIG. 23 shows the prize according to the type of game in step S104. It is a flowchart which shows the content of the lottery table determination process. First, the CPU 101 refers to bit 3 of the game type data to determine whether or not the game is an RB game (S104a). If it is determined that the game is an RB game, the CPU 101 selects the prize lottery table TBL17 indicated by the ADR17. (S104a1). If it is determined in step 104a that the RB game is not being played, it is determined whether or not the BB game is being played with reference to bits 0 to 1 of the game type data (S104b). Is selected (S104a1). If it is determined in step 104b that the BB game is not being played, it is determined whether or not the RB internal game is being played with reference to bit 7 of the game type data (S104c). The prize lottery table TBL15 indicated by the ADR 15 is selected (S104c1). If it is determined in step 104c that the RB internal game is not being played, it is determined whether or not the BB internal game is being played with reference to bit 6 of the game type data (S104d), and it is determined that the BB internal game is being played. In this case, the prize lottery table TBL14 indicated by the ADR 14 is selected (S104d1). If it is determined in step 104d that the game is not in the BB internal game, it is determined whether or not the normal game RT2 is being played with reference to bit 5 of the game type data (S104e). The prize lottery table TBL13 indicated by the ADR 13 is selected (S104e1). If it is determined in step 104e that it is not in the normal game RT2, it is determined whether or not it is in the normal game RT1 with reference to bit 4 of the game type data (S104f). The prize lottery table TBL12 indicated by the ADR 12 is selected (S104f1). If it is determined in step 104f that the game is not in the normal game RT1, the game is indicated as being in the normal game, so the prize lottery table TBL11 indicated by ADR11 is selected and the process is terminated (S104g).

  In the base game RT1 and the base game RT2, the replay probabilities of the replay 1-2 prizes are 2630 for the replay prize 1 and 100 for the replay prize 2 in the base game RT1, and replay prizes in the base game RT2. 1 is 100 and the re-game award 2 is 5500, which is set with a higher probability than in the normal game. On the other hand, in the normal game RT1 and the normal game RT2, the lottery probabilities of the small role C prize, the small role B prize, the small role A prize, the RB prize, the BB2 prize, and the BB1 prize are set to be the same as in the normal game. . As a result of the above, the lottery probability divided into the lost games in the base game RT1 and the base game RT2 is lower than the base game in the base game RT1 because the lottery probability of the replay prizes 1 and 2 is high. ing.

  The winning probabilities of the small role C prize, the small role B prize, the small role A prize, and the replay 1-2 prizes in the BB inside game and the RB inside game are set to be the same as in the normal game. Also, the RB prize, BB2 prize, and BB1 prize lottery probabilities in the BB inside game and RB inside game are each “0/16384” and are not subject to lottery.

  During the BB game and the RB game, the lottery probabilities for determining any one of the small role C prize, the small role B prize, the small role A prize or the loser by lottery are “200”, “15800”, “300”, respectively. , “84”, and the winning flag of the winning prize is set. Thus, during the BB game and during the RB game, the lottery probability of the small role B prize is higher than that during the normal game and the inside game. In this embodiment, in the BB game, only the small role B prize has a high probability of lottery, but the small role A prize, the small role B prize and the small role C prize are all high probability, or the small role A prize, The B prize and the small part C prize may have the same lottery probability as that of the base game or the internal medium game, and a small part prize dedicated to the BB game or the RB game may be provided. In any case, during the BB game, the combination probability of the small role award (the sum of the lottery probabilities of a plurality of small role awards) is higher than that during the normal game and the internal middle game.

<5-3: Winning flag set processing>
FIG. 11 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 value 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, and even if the random number value is different even in the same prize lottery table, the winning flag to be set is also different. In addition, when there is a carry-over flag that is a win flag carried over from the previous game, at least one win flag is set by combining the carry-over flag and the random value acquired in the game.

  First, the CPU 101 determines whether or not the small role C prize has been won based on whether or not the acquired random number value belongs to the range indicated by the lottery division data of the small role C prize in the prize lottery table (S105a). If it is determined, the small combination C winning flag of bit 4 of the winning information 2 data is set to “1” (S105a1).

  Next, the CPU 101 determines whether or not the small role B prize has been won based on whether the acquired random number value belongs to the range indicated by the lottery division data of the small role B prize in the prize lottery table (S105b). Is determined, the small combination B winning flag of bit 3 of the winning information 2 data is set to “1” (S105b1).

  Next, the CPU 101 determines whether or not the small role A prize is won based on whether or not the acquired random number value belongs to the range indicated by the lottery classification data of the small role A prize in the prize lottery table (S105c). Is determined, the small combination A winning flag of bit 2 of the winning information 2 data is set to “1” (S105c1).

  Next, the CPU 101 determines whether any of bits 0 to 3 and bits 6 to 7 of the game type data is set to “1” in the normal game, the normal game RT1, or the normal game RT2. Is checked (S105d), and if any of the bits is set to “1” and it is determined that the normal game is not in the normal game RT1 or the normal game RT2, the process proceeds to step S105j. If it is determined in step S105d that the game is in the normal game, the normal game RT1, or the normal game RT2, whether or not the RB prize is won is determined based on the RB prize lottery classification data in the prize lottery table. Is determined (S105e), and if it is determined to belong, the RB winning flag of bit 3 of the winning information 1 data is set to “1” (S105e1).

  Next, the CPU 101 determines whether or not the BB2 prize has been won based on whether or not the acquired random number value belongs to the range indicated by the lottery classification data of the BB2 prize in the prize lottery table (S105g). In such a case, the BB2 winning flag of bit 1 of the winning information 1 data is set to “1” (S105g1).

  Next, the CPU 101 determines whether or not the BB1 prize has been won based on whether or not the acquired random number value belongs to the range indicated by the lottery classification data of the BB1 prize in the prize lottery table (S105h). In such a case, the BB1 winning flag of bit 0 of the winning information 1 data is set to “1” (S105h1).

  Next, the CPU 101 determines whether or not the BB game or the RB game is in progress by checking whether any of the bits 0 to 3 of the game type data is set to “1” (S105j). If it is determined that the game is being played or the RB game is being played, this process is terminated. If it is determined in step S105j that the BB game or the RB game is not being played, the range in which the lottery classification data of the replay 2 prize in the prize lottery table indicates whether or not the replay 2 prize has been won (S105k), if it is determined that it belongs, the replay 2 winning flag of bit 1 of the winning information 2 data is set to “1” (S105k1).

  Next, the CPU 101 determines whether or not the replay 1 prize has been won based on whether or not the acquired random number value belongs to the range indicated by the replay 1 prize lottery classification data in the prize lottery table (S105m). Is determined, the replay 1 winning flag of bit 0 of the winning information 2 data is set to “1” (S105m1). Thereafter, this process is terminated.

  In addition, in the flowchart shown in FIG. 11, when there is a carry-over flag from the previous game, it is clearly indicated that when a new prize is won in this game, a plurality of winning flags are set simultaneously. However, when a new prize is won, a bit corresponding only to the prize is set to “1” without affecting other bits, so that a plurality of bits may be set to “1” at the same time. . In this example, the winning information 1 data is stored as a storage device that stores the winning flag corresponding to the start prize, and the winning information 2 data is stored as a storage device that stores the winning flags corresponding to the replay 1-2 prize and the small role prize. However, they may be stored in the same storage device. The plurality of bits being “1” means that the plurality of bits are “1” considering the winning information 1 data and the winning information 2 data together. In addition, as winning information, a prize is assigned to each bit and managed as a flag as to whether or not the winning is performed. However, if it is “01H”, the replay 1 prize is won, and if it is “02H”, the small role A prize is won. You may make it manage with a numerical value.

<5-4: Stop data selection process>
FIG. 12 is a flowchart showing the contents of the stop link table selection process in step S106. In this stop data selection process, 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 stop positions are specified according to the stop operation order. The stop display is performed while sequentially selecting. FIG. 13 is an explanatory diagram showing the data structure of the stop link table. The stop link table is categorized for each award to be drawn in the internal lottery. (A) Stop link table TBL21-1 for replay 1 (B) Stop link table TBL23 for small role B and (C) For BB1 A stop link table TBL27 is provided. The stop link tables TBL21 to TBL29 are classified when the first stop operation is the left reel R1, the middle reel R2, and the right reel R3, and the symbols constituting the award are displayed in the upper, middle, and lower stages. It is classified according to which one is stopped, and further classified according to the type of winning line.

  The structure of the table will be described using the replay 1 stop link table TBL21-1 shown in FIG. The stop link table is divided into three data groups (a) to (c) depending on whether the first stop operation is the left reel R1, the middle reel R2, or the right reel R3. That is, when the replay 1 prize is won and the first stop operation is the left reel R1, the data group (a) of the TBL 21-1 is selected, and the first stop operation is performed on the middle reel R2. If there is, the data group (b) of TBL 21-1 is selected. If the first stop operation is the right reel R3, the data group (c) of TBL 21-1 is selected.

  Next, the stop data table used for the first left reel R1 is selected depending on whether the blue plum symbol constituting the combination relating to the replay 1 prize is stopped at any one of the upper, middle and lower stages. The selection of whether the symbol is to be stopped at the upper, middle or lower level will be described in detail later, but in which step the symbol to be stopped is displayed according to the stop operation symbol position of the player's stop operation timing. There are a method of setting in advance for each stop operation symbol position, a method of determining at which stage the stop operation symbol position can be stopped, and a method of determining by lottery when there are a plurality of candidates. In the case of a game in which only one winning line (L1 line) is valid, it is determined as the middle stage.

  For example, when the left reel R1 is selected by the first stop operation and the data group (a) of the TBL 21-1 is selected, the stop data table TBL102 is selected when stopping at the upper stage of the left reel R1, and stopped at the middle stage. When stopping, the stop data table TBL101 is selected, and when stopping at the lower stage, the stop data table TBL103 is selected. Here, when the stop data table TBL103 is selected and the blue plum symbol is displayed in the lower stage of the left reel R1, in the second stop operation, the lower stage of the left reel R1 includes the L3 line and the L5 line included in the winning line. Is a candidate. Further, stop data to be selected depending on whether the second stop operation is the middle reel R2 or the right reel R3 is determined by the stop operation order. That is, when the middle reel R2 is selected in the second stop operation, the stop data table TBL203 displayed in the lower row or the stop data table TBL201 displayed in the middle row is selected. On the other hand, when the right reel R3 is selected in the second stop operation, the stop data table TBL303 displayed in the lower row or the stop data table TBL302 displayed in the upper row is selected. For example, when the stop data table TBL201 is selected and the blue plum symbol is displayed in the middle stage of the middle reel R2, the stop data table TBL302 which is the upper stage of the remaining right reel R3 is selected in the third stop operation, and the winning line The blue plum symbols are displayed on L5.

  When the middle reel R2 is selected by the first stop operation and the data group (b) of the TBL 21-1 is selected, only the TBL 201 to be stopped at the middle stage of the middle reel R2 can be selected, and the cherry symbol and plum are selected on the left reel R1. In order to prevent the symbols from being displayed at the same time, the plum symbol needs to be displayed in the middle, and cannot be stopped in the upper and lower stages of the middle reel R2, so the blue plum symbol is displayed in the middle. Next, regardless of whether the second stop operation is the left reel R1 or the right reel R3, TBL101 or TBL301 is selected and displayed so that the blue plum symbols are arranged only on the pay line L1.

  Similarly, when the right reel R3 is selected in the first stop operation and the data group (c) of TBL 21-1 is selected, only the TBL 301 to be stopped at the middle stage of the right reel R3 can be selected, and the cherry on the left reel R1 is selected. In order to prevent the symbols and the plum symbol from being displayed at the same time, the plum symbol needs to be displayed in the middle, and the upper and lower portions of the right reel R3 cannot be stopped. Therefore, the blue plum symbol is displayed in the middle. Next, regardless of whether the second stop operation is the left reel R1 or the middle reel R2, TBL101 or TBL201 is selected and displayed so that the blue plum symbols are arranged only on the winning line L1.

  In the small link B stop link table TBL23 shown in FIG. 13 (B), when the data group (a) of TBL23 is selected, the bell symbol is displayed according to the stop operation symbol position of the player's stop operation timing. Display on either the top, middle or bottom. On the other hand, when the data group (b) of TBL23 or (c) of TBL23 is selected, it is necessary to display the bell symbol in the lower stage in order to prevent the cherry symbol and the bell symbol from being displayed simultaneously on the left reel R1. Therefore, the bell symbols are displayed so as to line up on the winning line L3 or L5.

  In the stop link table TBL27 for BB1 shown in FIG. 13C, even if the data group of (a) of TBL27, (b) of TBL27, or (c) of TBL27 is selected, the stop operation at the stop operation timing of the player Depending on the symbol position, the red 7 symbols are displayed on every winning line.

  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. 14, the stop data tables TBL101 to TBL179, TBL201 to TBL279 corresponding to each reel R1 to R3, and each prize and loss, It consists of TBL301 to TBL379. 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 if 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. In this embodiment, since the blue plum symbol is arranged on the lower side of all the bell symbols on the right reel R3, the stop data table TBL321 that displays the bell symbol on the middle row and the stop data table TBL303 that displays the blue plum symbol on the lower row. Can be shared by one stop data table.

  Returning to FIG. First, the CPU 101 refers to bit 0 of the winning information 2 data to determine whether or not the replay 1 winning flag is set (S106a). If it is determined that the replay 1 winning flag is set, the replay 1 stop link is determined. The table TBL21-1 is selected (S106a1).

  Next, the CPU 101 refers to bit 1 of the winning information 2 data to determine whether or not the replay 2 winning flag is set (S106a2). If it is determined that the replay 2 winning flag is set, the replay 2 stop is performed. The link table TBL21-2 is selected (S106a3).

  Next, the CPU 101 refers to bit 4 of the winning information 2 data to determine whether or not the small role C winning flag is set (S106b). The link table TBL22 is selected (S106b1).

  Next, the CPU 101 determines whether or not the small role B winning flag is set by referring to bit 3 of the winning information 2 data (S106c). The link table TBL23 is selected (S106c1).

  Next, the CPU 101 refers to bit 2 of the winning information 2 data to determine whether or not the small role A winning flag is set (S106d). The link table TBL24 is selected (S106d1), and this process ends.

  Next, the CPU 101 refers to bit 3 of the winning information 1 data to determine whether or not the RB winning flag is set (S106e). If it is determined that the RB winning flag is set, the CPU 101 stores the RB stop link table TBL25. Selection is made (S106e1), and this processing is terminated.

  Next, the CPU 101 refers to bit 1 of the winning information 1 data to determine whether or not the BB2 winning flag is set (S106g). If it is determined that the BB2 winning flag is set, the CPU 101 stores the BB2 stop link table TBL26. Select (S106g1), and the process is terminated.

  Next, the CPU 101 refers to bit 0 of the winning information 1 data to determine whether or not the BB1 winning flag is set (S106h). If it is determined that the BB1 winning flag is set, the CPU 101 stores the BB1 stop link table TBL27. Selection is made (S106h1), and this processing is terminated.

  Finally, if one winning flag is not set, the CPU 101 selects the stop link table for losing TBL29 (S106p), and ends this processing.

  FIG. 15 is an explanatory diagram showing a data structure of a stop data table used for stopping the right reel R3. 15A shows the symbol arrangement of the right reel band, and FIGS. 15B, 15C and 15D show the replay 1 stop data table TBL301, the small role B stop data tables TBL321 and BB1, respectively. The stop data table TBL361 is shown. These stop data tables indicate “0” to “4” indicating that the frame is advanced from the symbol position (stop operation symbol position) immediately before the stop position where the stop operation instruction signal 113c is detected to the number of symbols ahead. The number of frames up to is stored. “0” means to stop at the stop operation symbol position, and “4” means to stop at the symbol position four frames ahead. Since the stop data table only needs to be able to instruct where the symbol is advanced and stopped, the symbol number PN to be stopped may be stored instead of the number of advance frames such as “0” to “4”. Good.

  The replay 1 stop data table TBL301 can stop the blue plum symbol in the middle regardless of the symbol number (stop operation symbol number) of the stop operation symbol position. Also, in the small role B stop data table TBL321, the bell symbol can be stopped at the middle stage regardless of the stop operation symbol number. In this way, if five of the 21 symbols are arranged within an interval of 4 frames, the symbol can always be stopped at the middle stage regardless of the symbol number. Such a blue plum symbol and bell symbol are called 100% retracted symbols.

  On the other hand, in the BB1 stop data table TBL361, the red 7 symbols can be stopped in the middle only at 5 locations where the stop operation symbol numbers are “5” to “9” (winning pull-in range). When the stop operation symbol numbers are “1” to “4” (winning pull-in range), “10” to “14” (winning pull-in range), and “15” to “21” (winning pull-in range), BAR The symbol, the white 7 symbol, and the watermelon symbol are stopped in the middle.

  For example, when the player's stop operation timing is a symbol number (stop operation symbol number) PN = 7, when the stop data table TBL301 for re-game 1 is selected, the number of advance frames “3” is acquired. Then, when the stop operation symbol number is advanced three frames, the blue plum symbol with symbol number PN = 10 is displayed in the middle, and when the small data B stop data table TBL321 is selected, the advance frame number “0” is acquired. Then, the bell symbol of the symbol number PN = 7 is displayed in the middle without proceeding from the stop operation symbol number. When the BB1 stop data table TBL361 is selected, the advance frame number “2” is acquired, and two frames are advanced from the stop operation symbol number to display the red 7 symbol of symbol number PN = 9 in the middle row. Depending on the stop data table selected in this way, even if the same stop operation symbol number is used, the symbols to be stopped in the middle stage are different.

<5-5: Reel stop processing>
16 to 17 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 as to automatically stop if no operation is performed and the automatic stop time from the reference time to the last stop of the reel. 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 determines whether or not the automatic stop time has elapsed from the reference time (whether or not the timer value indicating the remaining time has become 0) (S109a) and whether or not the first stop button stop operation has been performed. Is determined based on the stop operation instruction signals 113a to 113c (S109b).

  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 a symbol number (stop operation symbol number) immediately after the stop operation is acquired (S109c). Specifically, the stop button number and the stop operation symbol number at the timing are acquired by detecting stop operation instruction signals 113a to 113c that are output when the stop buttons 13a to 13c are pressed. In this example, stop button numbers “1”, “2”, and “3” are assigned to the stop buttons 13a, 13b, and 13c, respectively.

  On the other hand, if it is determined in step S109a that the automatic stop time has elapsed, the stop button number “3” and stop operation 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 reel stop data table group 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 stopped at any one of an upper stage, a middle stage, and a lower stage. In the case of the left reel R1, a winning line L2 or L4 is a winning line candidate if it can be stopped in the upper stage, a winning line L1 if it can be stopped in the middle stage, or a winning line L3 or L5 if it can be stopped in the lower stage. In the case of the middle reel R2, a winning line L2 is a candidate for the winning line if it can be stopped in the upper stage, a winning line L1, L4 or L5 if it can be stopped in the middle stage, and a winning line L3 if it can be stopped in the lower stage. In the case of the right reel R3, a winning line L2 or L5 is a winning line candidate if it can be stopped in the upper stage, a winning line L1 if it can be stopped in the middle stage, or a winning line L3 or L4 if it can be stopped in the lower stage. If it is possible to stop at a plurality of stages, one stop data table for a predetermined line is selected by lottery or the like from among the winning line candidates combining them (S109f).

  Next, the CPU 101 acquires the advance frame number corresponding to the acquired stop operation symbol number (S109g), and stops the reel that has been stopped based on the advance frame number (S109h).

  Next, the CPU 101 determines whether or not the automatic stop time has elapsed from the reference time (the timer value indicating the remaining time has become 0) and (S109j) whether or not the second stop button stop operation has been performed. The determination is made based on the stop operation 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, a stop button number indicating the type of the stop button is acquired from the detected stop operation instruction signals 113a to 113c, and a symbol number (stop operation symbol number) immediately after the stop operation is acquired (S109m).

  On the other hand, if the automatic stop time has elapsed in step S109h, the stop button number and stop operation 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 stop position of the already stopped reel based on the stop button number (S109p).
Next, the CPU 101 acquires the advance frame number corresponding to the acquired stop operation symbol number (S109q), and stops the reel that has been stopped based on the advance frame number (S109r).

  Next, the CPU 101 stops whether or not the automatic stop time has elapsed from the reference time (the remaining time indicated by the timer value has expired) and whether or not the third stop button stop operation has been performed (S109s). The determination is made based on the operation 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, a stop button number indicating the type of the stop button is acquired from the detected stop operation instruction signals 113a to 113c, and a symbol number (stop operation symbol number) immediately after the stop operation is acquired (S109u).

  On the other hand, if the automatic stop time has elapsed in step S109s, the stop button number and stop operation 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 winning is 100%, the process proceeds to step S109w.

Next, the CPU 101 determines a stop data table adapted to the stop position of the already stopped reel based on the stop button number (S109w).
Next, the CPU 101 acquires the advance frame number corresponding to the acquired stop operation symbol number (S109x), stops the reel that has been stopped based on the advance frame number (S109y), and ends the process.

  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>
18 to 19 are flowcharts 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 after the reels are stopped is checked to determine whether or not a winning is achieved. If it is determined that a prize has been won, a process for starting another type of game is performed if the prize is a start prize, and a payout is awarded if the prize is a small 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 (S110a1).

  Next, the CPU 101 determines whether or not a replay 2 award has been won (S110b). If it is determined that a win has been won, the replay 2 winning flag of bit 1 of the winning information 2 data is cleared (S110b1). Subsequently, referring to bits 6 to 7 of the game type data, it is determined whether or not an internal game is being played (S110b2). If it is determined that the game is not being played, the normal RT1 medium flag of bit 4 of the game type data is set. When the flag is cleared (S110b3), the normal RT2 flag in bit 5 is set (S110b4), and the number of games to be set as the normal game RT is set to 10 (S110b5). Subsequently, an automatic bet process is performed (S100a in FIG. 8), and the process returns to step S101.

  Next, the CPU 101 determines whether or not a replay 1 prize has been won (S110c). If it is determined that a win has been won, the replay 1 winning flag of bit 0 of the winning information 2 data is cleared (S110c1). Subsequently, referring to bits 6 to 7 of the game type data, it is determined whether or not an internal game is being played (S110c2). If it is determined that the game is not being played, the normal RT2 flag in bit 5 of the game type data is set. Clear (S110c3), set the normal RT1 flag of bit 4 (S110c4), and set the number of games to be the normal game RT to 100 (S110c5). Subsequently, an automatic bet process is performed (S100a in FIG. 8), and the process returns to step S101.

  Next, the CPU 101 determines whether or not a small role C prize has been won (S110d). If it is determined that a prize has been won, a payout process for two medals is performed (S110d1). Subsequently, it is determined whether or not the small role B prize has been won (S110e). If it is determined that the prize has been won, a payout process for 10 medals is performed (S110e1). Subsequently, it is determined whether or not a small role A prize has been won (S110f). If it is determined that a prize has been won, a payout process for 15 medals is performed (S110f1). 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 an RB prize has been won (S110g). If it is determined that a prize has been won, an RB game flag in bit 3 of the game type data is set to "1" (S110g1). . Subsequently, the maximum small part winning number (remaining winning number) in the RB game is set to 8, and the maximum game number (remaining maximum game number) is set to 12 (S110g2).

  Next, the CPU 101 determines whether or not the BB1 award to the BB2 award has been won (S110h). If it is determined that a prize has been won, the CPU 101 sets the BB game in-progress flag of any of bits 0 to 1 of the game type data to “ 1 ”(S110h1), and the acquired number counter is cleared (S110h2).

  Next, the CPU 101 further sets the RB game flag of bit 3 of the game type data to “1” (S110h3). Subsequently, the maximum small role 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 (S110h4). By the processing of steps S110h3 and S110h4, the RB game can be started from the first game of the BB game. If steps S110h3 to S110h4 are omitted, the RB game is not executed immediately after the start of the BB game, and the RB game can be started when winning the RB award. Thereafter, this process is terminated.

<5-7: Game end determination process>
20 to 21 are flowcharts showing the contents of the game end determination process in step S111. In this game end determination process, it is determined whether or not the end condition is satisfied in the game for which the end condition is set.

  First, the CPU 101 refers to bit 3 of the game type data to determine whether or not it is an RB game (S111a), and if it is determined that the RB game is not being performed, the process proceeds to step S111h.

  On the other hand, if it is determined in step S111a that the RB game is in progress, it is determined whether or not a prize has been awarded by winning the small role prize in this game (S111b). When a prize is awarded after winning the small role award, the remaining small role winning number is subtracted (S111c), and then it is determined whether the remaining small role winning number has reached 0 (S111d). If it is determined that the number of small part winnings has reached 0, the RB game flag in bit 3 of the game type data is cleared (S111g).

  On the other hand, if it is determined in step S111d that there is a remaining small role winning number, the remaining winning number is displayed on the acquired number display 23b, and the remaining game number is subtracted (S111e). Subsequently, it is determined whether or not the remaining number of games has reached 0 (S111f). If it is determined that the remaining number of games has reached 0, the RB game flag is cleared (S111g), and there is a remaining number of games. Is determined, the remaining number of games is displayed on the acquired number display 23b.

  Next, the CPU 101 refers to bits 0 to 2 of the game type data to determine whether or not the BB game is in progress (S111h), and if it is determined that the BB game is not in progress, the process proceeds to step S111q.

  On the other hand, if it is determined in step S111h that the BB game is in progress, it is determined whether or not a small role prize is won and a dividend is awarded in this game (S111j). When the small prize is awarded and a payout is awarded, the payout is added to the acquired number counter value (S111k), and the acquired number is displayed on the acquired number display 23b (S111m).

  Next, the CPU 101 compares the acquired number counter value with the acquired number upper limit determination value determined in each BB game (S111n). The acquired number upper limit determination value is a value that is 15 smaller than the acquired number upper limit value that must not be exceeded during the game, determined in each BB game. If the acquired number upper limit determination value is exceeded in step S111n, the BB game flag and the RB game flag (bits 0 to 3 of the game type data) are cleared (S111p).

  Next, the CPU 101 refers to bits 0 to 3 of the game type data to determine whether the BB game is in progress and not in the RB game (S111q), and whether the BB game is in progress or the BB game is in progress. If it is determined that the game is in progress, the process proceeds to step S111t.

  On the other hand, if it is determined in step S111q that the game is in the BB game but is not in the RB game, the RB game flag in bit 3 of the game type data is set to “1” again (S111r), and then in the RB game. The maximum small role winning number (remaining winning number) is set to 8 and the maximum game number (remaining maximum game number) is set to 12 (S111s). By the processing of steps S111r and S111s, in the BB game, a new next RB game is started from the next game after one RB game is completed, and the RB game is continuously executed. If steps S111r to S111s are omitted, the RB game is not continuously executed, and the RB game can be started when the RB prize is won. The game that is in the BB game but not in the RB game is a game in which one RB game is completed by satisfying the end condition of the maximum number of small winnings or the maximum number of games in the game, as described above. The game in which the RB game flag is cleared in step S111g. Therefore, in this game, the RB game flag is once cleared in step S111g, and the RB game flag is set again in step S111r. Since the slot machine 1 outputs a game type signal synchronized with the RB game flag or the BB game flag to the hall computer connected to the outside, this RB game segment is clearly defined. The flag processing is performed.

  Next, the CPU 101 refers to bits 4 to 5 of the game type data to determine whether the game is in the normal game RT1 or the normal game RT2 (S111t), and determines that the game is not in the normal game RT1 or the normal game RT2 Ends this processing. If it is determined in step S111t that the game is in the normal game RT1 or the normal game RT2, the number of games to be RT is subtracted (S111u), and if it is determined that the remaining number of games has reached 0 (S111v), The normal RT flag in any of bits 4 to 5 of the game type data is cleared (S111w), and this process is terminated.

<5-8: Winning flag clear process>
FIG. 22 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, since the replay 1 winning flag, the replay 2 winning flag, the small role A winning flag, the small role B winning flag and the small role C winning flag are cleared in one game, the CPU 101 clears the winning information 2 data. Is cleared (S112a).

  Next, the CPU 101 determines whether or not the RB winning flag is set with reference to bit 3 of the winning information 1 data (S112b). If it is determined that the flag is set, the CPU 101 further determines the RB prize. It is determined whether or not a prize has been won (S112c). If it is determined that the RB combination has been established and the prize has been won, the RB winning flag is cleared (S112d). If it is determined in step S112c that the game has not been won, the RB internal game flag of bit 7 of the game type data is set to “1” (S112e), and the RB internal game is set from the next game.

  Next, the CPU 101 refers to bit 1 of the winning information 1 data to determine whether or not the BB2 winning flag is set (S112k). If it is determined that the flag is set, the CPU 101 further determines the BB2 award. It is determined whether or not a prize has been won (S112m). If it is determined that the BB2 combination has been established and the prize has been won, the BB2 winning flag is cleared (S112n) and the process is terminated. If it is determined in step S112m that the game has not been won, the BB internal game flag of bit 6 of the game type data is set to “1” (S112p), and the BB internal game is set from the next game.

  Next, the CPU 101 refers to bit 0 of the winning information 1 data to determine whether or not the BB1 winning flag is set (S112q). It is determined whether or not a prize has been won (S112r). If it is determined that the BB1 combination has been established and the prize has been won, the BB1 winning flag is cleared (S112s), and the process ends. If it is determined in step S112r that the game has not been won, the BB internal game flag in bit 6 of the game type data is set to “1” (S112t), the next game is changed to the BB internal game, and the process is terminated.

<Modification>
The present invention is not limited to the above-described embodiments, and for example, various modifications described below are possible.
(1) In the embodiment described above, two types of probability variation games such as the base game RT1 and the base game RT2 are adopted, but one type of probability variation game in which the winning probability of the replay 1 prize and the replay 2 prize changes. You may provide only. For example, a normal game RT may be employed as shown in FIG. In this case, the condition for shifting from the base game to the base game RT is to win the second replay prize. In addition, the condition for shifting from the normal game RT to the normal game is that the number of games of the normal game RT has reached 10 games or that a replay 1 prize has been won. In this case, the probability of winning the second replay prize is 1 / 2.9, and there is a possibility of winning once in a 2.9 game. On the other hand, when the number of games in the normal game RT reaches “10”, the game shifts to the normal game, but by that time, there is a much higher possibility of winning the replay 2 prize. Therefore, in actuality, winning the replay 1 prize is a condition for shifting to the normal game. In this slot machine, one probability variation game can be adopted to change the progress of the game.
Further, as shown in FIG. 24B, a condition for shifting from the base game RT to the base game may be that a predetermined number of games have elapsed (in this example, 10 games).
When the BB prize or RB prize is won in the normal game RT, the game shifts to the BB game or RB game, and when those games are finished, the game shifts to the normal game. The normal game RT has a high combined probability of the replay 1 award and the replay 2 award as high as 1/3. Once the normal game RT is shifted to the normal game RT, the player shifts to the BB game or the RB game without reducing the medals so much. Can be made.

(2) In the above-described embodiment, it is needless to say that three or more types of probability variation games adopting the base games RT1 and RT2 having different replay prize synthesis probabilities may be adopted. For example, in addition to the normal games RT1 and RT2, the normal game RT3 may be adopted. An example of the game state transition is shown in FIG. When each of the normal games RT1, RT2, and RT3 is continued N1, N2, and N3 times, the game state shifts to the normal game from the next game. In the normal games RT1, RT2, and RT3, one of the lottery targets including the regame 1 prize, the regame 2 prize, and the regame 3 prize is determined by lottery in the internal lottery. In addition, the symbols constituting these prizes are arranged so that they can be drawn and stopped on the winning lines L1 to L5 no matter what timing the player operates the reel stop buttons 13a to 13b. And When the winning probabilities of the replay 1 award, replay 2 award, and replay 3 award in the base game RT1 are p1, p2, and p3, p1>p2> p3. Further, when the winning probabilities of the replay 1 award, replay 2 award, and replay 3 award in the base game RT2 are q1, q2, and q3, q1> q2 and q1> q2. Furthermore, r1> r2 and r1> r2 when the winning probabilities of the replay 1 award, replay 2 award, and replay 3 award in the base game RT3 are r1, r2, and r3.
By adopting the base game RT3 in this way, the game preference can be further improved.
