Abstract

<P>PROBLEM TO BE SOLVED: To concentratedly produce a BB game despite a simple structure. <P>SOLUTION: In a regular period of a regular game and an RT game, BB prizes are assigned to all lottery divisions. In winning a minor winning combination prize and a replay prize, a stop control is executed to preferentially get the BB prize. This method allows only a game, which wins a lottery division 11 in an internal lottery and validates a winning flag of the BB1 prize, to win the BB1 prize. In the RT game, a probability of selecting the lottery division 10 is lowered compared with that of the regular game and, by just that much, the probability of selecting the lottery division 11 increases substantially 11 times more than that of the regular game. Therefore, RT game can improve a possibility of winning the BB prize. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

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

  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. In addition to the determination, a slot machine including special game storage mode transition lottery determination means is disclosed.

Further, in some conventional slot machines, when a big bonus prize is won by internal lottery, an RT game is executed during a carry-over period until the big bonus prize is won and the big bonus prize is won. In this slot machine, the right to shift to the big bonus was accumulated in the RT game during the carryover period, and the big bonus prize was continuously awarded after the end of the big bonus game.
JP 2004-229952 A

However, in the conventional slot machine, since the lottery for the 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.
In addition, if the big bonus prize was not won in the special game storage mode, the big bonus was not started even if the lottery for the transition to the special game release mode was won.
In addition, in order to prevent the right to shift to the big bonus as much as possible, it is necessary to lengthen the period of the RT game or increase the probability of winning the big bonus prize in the internal lottery. However, if the RT game period is lengthened, the bonus game does not continue in a short time. On the other hand, if the RT game period is shortened and the probability of winning the big bonus prize is increased, the bonus game is too continuous and the payout becomes excessive. For this reason, it is not established as a slot machine.
The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a slot machine capable of concentrating and executing a big bonus prize in a short time only by internal lottery.

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 problems, the present invention is provided with a plurality of display rows (R1, R2, R3) in which a plurality of types of symbols are arranged and variable display is possible for each game that can be started when a game value is received. ), And when the stop mode in the state in which the variable display of the plurality of display columns (R1, R2, R3) is stopped is a predetermined mode, a prize is won and a value determined in advance according to the winning prize is obtained. The game includes a normal game and one or more special games with higher value than the normal game, and the prize does not accept the game value as the value. In addition, one or more kinds of re-game prizes for starting the next game, one kind or two or more kinds of small prizes for giving the predetermined game value as the value, and the kind of the game as the value Normal A slot machine (1) including one or two or more types of special game start prizes to be transferred from a game to any one of the special games, one of the prizes to be drawn A lottery means (101, TBL11 to TBL13) which draws lots so that two or more types of prizes can be won at the same time, or draws lottery results so as not to win any of the prizes, and uses the lottery results as lottery results. And a lottery result holding means (101, S112a) for holding a lottery result won in the special game start prize as a carry-over game period after winning one of the special game start prizes. , S112j), and when the lottery result indicates winning of any one of the prizes based on the lottery result, the lottery result indicates winning. If each of the display columns (R1, R2, R3) is stopped so that one or more of the prizes are won, and the lottery result does not indicate any prize among the prizes, Display row stop means (101, S109) for stopping the display rows (R1, R2, R3) so as not to win any of the awards, and any of the special game start prizes in the base game When winning, the game type is changed from the normal game to the special game corresponding to the special game start prize type, and the special game is continued until the special game end condition corresponding to the special game is satisfied. Management means (101), wherein the lottery means (101, TBL11 to TBL13) is a small game prize or a prize in a base game other than the carryover game period. Is a simultaneous lottery in which at least one of the replay prizes and at least one of the special game start prizes are won at the same time, or an individual having only at least one of the special game start prizes as a prize. For each type of the special game start award, the probability of winning the special game start award that is the target of the simultaneous win and the special game start award that is the target of the individual win The lottery is executed such that the total probability of winning is constant, and the special game held by the lottery result holding means from the prize for the lottery is held in the regular game during the carry-over game period. It is possible to perform a lottery by excluding the game start prize and not to win any of the prizes. 101, S109), when the lottery result of the lottery means (101, TBL11 to TBL13) indicates winning of at least one of the small role award or the replay award, Each display row (R1, R2, R3) is stopped so that at least one of the prizes for winning a prize or the replay prize that has been preferentially won is selected, and is subject to the simultaneous winning. Only the at least one special game start prize that is the target of the individual winning is obtained by further including a probability adjusting means for changing a probability of winning at least one kind of prize among the small role prize or the replay prize. The probability of winning is adjustable.

  According to the present invention, in the base game other than the carryover game period, for each type of special game start prize, at least one kind of prizes and special game start prizes among small prizes or replay prizes to be simultaneously elected There is a trade-off relationship between the probability of winning at the same time and the probability of winning only the special game start prize that is the target of individual winning. By varying the probability that at least one of the small role award or replay award and the special game start prize will be won simultaneously, the probability of winning only the special game start prize will vary, resulting in special The probability of winning the game start prize can be adjusted.

  If the conditions change, the winning probability of the whole special game start prize is “the probability of winning the special game start prize that is the target of the simultaneous winning and the probability of winning the special game start prize that is the target of the individual win. May be changed. For example, when there are two types of normal games and the transition from one normal game to another normal game is triggered by something, the total probability in one normal game is different from the total probability in another normal game. Also good.

  Furthermore, the lottery means performs a lottery by excluding the special game start prize held as the lottery result won by the lottery result holding means from the prizes to be drawn in the base game during the carryover game period. In addition, it is possible to make a lottery so as not to win any of the awards, and the probability of not winning any of the awards other than the carryover game period. Compared to the normal game, the probability assigned to the excluded special game start prize may be increased. In this case, in the normal game during the carry-over game period, the probability of losing is in a trade-off relationship with respect to the probability that at least one kind of prize is won out of the small role prize or the replay prize. By changing the probability of winning at least one of the small role award or replay award, the probability of losing will change and the lottery result will carry over the special game start award. The probability of winning the game start prize can be adjusted.

  Further, in another slot machine according to the present invention, a plurality of types of symbols are arranged in each, and a plurality of display columns (R1, R2, R3) that can be variably displayed for each game that can be started upon receipt of a game value. ), And when the stop mode in the state in which the variable display of the plurality of display columns (R1, R2, R3) is stopped is a predetermined mode, a prize is won and a value determined in advance according to the winning prize is obtained. The game includes a normal game and one or more special games with higher value than the normal game, and the prize does not accept the game value as the value. In addition, one or more kinds of re-game prizes for starting the next game, one kind or two or more kinds of small prizes for giving the predetermined game value as the value, and the kind of the game as the value Said A slot machine (1) including one type or two or more types of special game start prizes to be transferred from a game to one of the special games. A lottery means (101, TBL11 to TBL13) which draws lots so that more than one kind of prizes can be won at the same time, or draws lottery so as not to win any of the prizes, and uses the lottery result as a lottery result; The lottery result holding means (101, S112a, and the like) holds the lottery result won in the special game start prize as a carryover game period after winning one of the special game start prizes. S112j) and, based on the lottery result, when the lottery result indicates winning of any one of the prizes, before the lottery result indicates winning If each of the display columns (R1, R2, R3) is stopped so that one or more of the prizes are won, and the lottery result does not indicate any prize winning of the prizes, Display row stop means (101, S109) for stopping each of the display rows (R1, R2, R3) so as not to win any of the awards, and any of the special game start prizes in the base game When a prize is won, the game type is shifted from the normal game to the special game corresponding to the special game start prize type, and the special game is continued until the special game end condition corresponding to the special game is satisfied. A game management means (101), wherein the lottery means (101, TBL11 to TBL15) receives the small role award in a base game other than the carryover game period. Or, among the replay prizes, at least one kind of prize and at least one kind of the special game start prize are won at the same time, or only the at least one kind of the special game start prize is won. A lottery for individual winning is possible, and for each type of the special game start prize, the probability of winning the special game start prize that is the target of the simultaneous winning and the special game start prize that is the target of the individual prize The lottery is executed so that the total probability of winning is fixed, and in the regular game during the carryover game period, the lottery result holding means (101, S112a, S112j) wins from the prize to be drawn As a result, a lottery may be performed excluding the special game start prize that is held, and so that none of the awards will be won. The display row stopping means (101, S109) indicates that the lottery result indicates winning of at least one kind of prize among the small role prize or the replay prize to be the target of the simultaneous winning. The display columns (R1, R2, R3) are stopped so that none of the special game start prizes are won, and at least one kind of the small prize or the replay prize that is the subject of the simultaneous winning is selected. By further including a probability adjusting means for changing the probability of winning a prize, it is possible to adjust the probability of winning only the at least one special game start prize that is a target of the individual winning.

  According to the present invention, the display row stopping means does not win any special game start prize when the lottery result indicates winning of at least one kind of prize for the small role or replay prize to be simultaneously elected. Stop each display column as follows. In this case, it is not always necessary to win at least one type of prize among the small prizes or replay prizes for which the lottery results are the targets of simultaneous winning. For example, the special game start award may not be won as a result of the control for stopping the symbols constituting the small winning prize or re-playing award to be simultaneously elected close to the winning line.

According to this invention, the sum of the probability of winning the special game start prize that is the target of simultaneous winning and the probability of winning the special game start prize that is the target of individual winning is constant for each type of special game start prize. Since the lottery is executed, the special game is changed by changing the probability that at least one of the small role award or the replay award and the special game start prize are won simultaneously in the base game other than the carryover game period. The probability of winning only the start prize varies, and as a result, the probability of winning the special game start prize can be adjusted.
Furthermore, the lottery means performs a lottery by excluding the special game start prize held as the lottery result won by the lottery result holding means from the prizes for the lottery in the base game during the carryover game period. In addition, it is possible to make a lottery so as not to win any prize among the prizes, and the probability of not winning any prize among the prizes other than the carryover game period. In comparison with the normal game, the probability assigned to the excluded special game start prize may be increased. In this case, in the regular game during the carry-over game period, the probability of losing is in a trade-off relationship with respect to the probability that at least one kind of prize is won in the small role award or the replay prize. By changing the probability of winning at least one of the small role award or replay award, the probability of losing will vary and the lottery result will carry over the special game start award. The probability of winning the game start prize can be adjusted.

As a specific aspect of the above-described slot machine, the game value includes game media, and the small role award pays out a number of game media including zero according to the type of the small role award as the value. Preferably, the special game is more advantageous to the player in terms of the game medium payout condition than the normal game.
In this case, what is used for the game is a game medium, and the game medium is paid out when the small role prize is won. Therefore, the paid game medium can be used for the game again. In addition, even if a small role award is won, there may be zero payouts. For example, even if a small role award is won, there is no payout, that is, there is no payout, but the number of game media corresponding to the award is stocked. (Memorize), and when another prize is awarded, the number of stocked game media may be paid out.

  Further, in the slot machine described above, the game medium can accept one or a plurality of game media for each game, and the winning mode is determined according to the number of the game media received and the type of the prize. Are preferably associated with each other. For example, this corresponds to a case where the winning determination mode is changed by changing a valid pay line depending on the number of game media received.

  In addition, at least one kind of small role award among the small role awards may be paid out by a smaller number of game media than the number of game media received for each game. Further, the one type or two or more types of small role awards are based on the number of game media necessary for starting one game, and the one type or two or more types of small role awards are drawn by lottery. When the sum of the products of the selected probabilities and the number of game media to be given is an expected value, the expected value is preferably smaller than the reference number of game media. In this case, since the number of game media to be paid out is smaller than the number of game media to be accepted, the number of game media held by the player decreases in the course of the normal game. Therefore, even if a lot of game media are paid out in the special game, it is possible to achieve a balance.

  Further, in the slot machine described above, the lottery means (101, TBL11 to TBL13) is the special game subject to the simultaneous winning for each type of the special game start prize in the normal game other than the carryover game period. Lottery so that the total of the probability of winning the starting prize and the probability of winning the special game starting prize subject to the individual winning is higher than the probability of not winning any of the prizes. And the total probability of winning the one or more types of small role awards in the special game is the total probability of winning the one type or two or more types of small role awards in the normal game. It is preferable that the lottery is executed so as to be higher in comparison.

  If the total of the probability of winning the special game start award that is the subject of simultaneous winning and the probability of winning the special game start award that is the subject of the individual win is small, at least one of the small role award or replay award Even if the probability of winning simultaneously with the special game start prize is adjusted, the probability of winning the special game start prize can only be finely adjusted. On the other hand, according to the present invention, since the lottery is executed so that the total probability is higher than the probability of not winning any of the prizes, the probability of winning the special game start prize is increased. It is possible to adjust in a large range. As a result, it is possible to provide a large degree of freedom in setting the payout rate.

In the slot machine described above, the lottery means (101, TBL11 to TBL13) starts at least one kind of the special game when a prize other than the special game start prize is won in the base game other than the carryover game period. It is preferable that lottery is not performed so that prizes are won at the same time and none of the prizes is won.
In this case, the probability of a so-called losing in a base game other than the carryover game period is zero. For this reason, it is possible to win simultaneously or individually. In either case, since the special game start prize is won, the probability can be set to 100%.

In the slot machine described above, the game management means (101) shifts the game type from the special game to a high-probability game when the special game end condition is satisfied, and the probability adjustment means (101) In the high-probability game, by reducing the probability of winning at least one of the small prizes or the replay prizes that are the targets of the simultaneous winning compared to the normal game, It is preferable to increase the probability of winning only the at least one special game start prize to be targeted.
According to the present invention, after the special game is over, the game shifts to a high-probability game in which the winning probability of at least one of the small role award or replay award is lowered. Thereby, after the special game ends, the probability of winning the special game start prize again increases, and the possibility that the special game can be continuously executed increases.

In the slot machine described above, the game management means (101) selectively shifts the game type from the special game to the high-probability game or the normal game when the special game end condition is satisfied, and the probability In the high-probability game, the adjusting means (101) lowers the probability of winning at least one type of the small role award or the replay award that is the target of the simultaneous winning as compared with the normal game. Accordingly, it is preferable to increase the probability of winning only the at least one special game start prize that is the target of the individual winning.
According to the present invention, after the special game is over, the game shifts to a high-probability game in which the winning probability of at least one of the small role award or replay prize is lowered, or shifts to a normal game. As a result, when a transition is made to a high-probability game after the end of the special game, the probability of winning the special game start prize again increases, and the possibility that the special game can be continuously executed increases.

In the slot machine described above, the special game start prize includes a plurality of types of special game start prizes, and the high probability game ends when the end condition of the high probability game is satisfied. And the plurality of high-probability games differ in at least one of the high-probability game end conditions or the probability that only the at least one special game start prize in the high-probability game is won, The lottery means (101, TBL11 to TBL13) draws lots so that the plurality of types of special game start prizes are not won at the same time in the base game other than the carryover game period, and the game management means (101) Depending on the type of special game start prize drawn by the lottery means (101, TBL11 to TBL13), any high probability game It is preferable that the correlated whether to shift to.
According to this invention, there are a plurality of special game start prizes and high probability games, and each special game start prize is associated with each high probability game. This makes it possible to shift to an advantageous high probability game when a special game start prize is won. As a result, various games can be executed.
Furthermore, if the small role prize that is drawn at the same time as a special game start prize is not drawn at the same time as another special game start prize, the player can be notified of the type of the special game start prize that has been won. In this case, if only the advantageous special game start prize is notified, the player's willingness to continue the game can be further enhanced.

In the slot machine described above, the special game start prize includes a plurality of types of special game start prizes, and the high probability game ends when the high probability game end condition is satisfied, and the lottery means (101, TBL11 to TBL11) TBL13) draws so that the plurality of types of special game start prizes are not won at the same time in the base game other than the carryover game period, and the game management means is drawn by the lottery means (101, TBL11 to TBL13). Depending on the type of the special game start prize, it is preferable to associate the transition to the high probability game or the normal game.
According to this invention, there are a plurality of special game start prizes, and each special game start prize is associated with whether to shift to a high-probability game or to a normal game. This makes it possible to shift to a high-probability game when a special game start prize is won.
Furthermore, if the small role prize that is drawn at the same time as a special game start prize is not drawn at the same time as another special game start prize, the player can be notified of the type of the special game start prize that has been won. In this case, the player's willingness to continue can be increased by designing so that only an advantageous special game start prize can be notified.

  In the slot machine described above, stop operation means (13a, 13b, 13c) provided corresponding to the plurality of display rows (R1, R2, R3) for allowing the player to input an instruction to stop the variable display. The display row stopping means (101, S109) further includes the lottery result and the stop operation means (13a, 13b, 13c) when the lottery result indicates winning of any one of the prizes. Each display row (R1, R2, R3) is stopped so that one or more of the prizes in which the lottery result indicates winning is won according to the relationship with the stop instruction input timing from Is preferred.

  Here, the display row stopping means (101, S109) causes at least one type of prize among the small prizes or the replay prizes to be simultaneously selected to win regardless of the stop instruction input timing. It is preferable to stop the display columns (R1, R2, R3). According to the present invention, since the prize that prevents the special game start prize from being won is 100%, the special game start prize is surely awarded when the small part prize or replay prize that is the subject of simultaneous winning is won. I can stop.

  In the slot machine described above, when the lottery result indicates the winning of the at least one special game start prize to be the target of the simultaneous winning, the display row stopping means (101, S109) Regardless of whether the display row (R1, R2, R3) is stopped so as to win the special game start prize, or the stop instruction means (13a, 13b, 13c) are instructed to stop in a specific order. It is preferable that the display columns are stopped so that a prize is awarded regardless of the input timing. According to the present invention, the special game start prize is 100% winning or 100% winning at the time of forward pressing. Therefore, if the stop instructing means is operated without pressing or in a specific order, the special game starting prize is always selected. Since winning a prize, it becomes easy to adjust the winning probability of the special game start prize.

  The slot machine described above includes a plurality of display rows (R1, R2, R3) each having a plurality of types of symbols arranged therein and capable of variable display for each game, and the plurality of display rows (R1, R2, R3). When the stop mode in the state where the variable display is stopped is a predetermined mode, a prize is awarded, and a predetermined value is given according to the prize awarded, and the game is given more than the regular game and the regular game One type or two or more types of special games with high value, and the prize includes one type or two for transferring the game type from the normal game to one of the special games as the value. A slot machine (1) including one or more types of special game start prizes and one or more types of block prizes for preventing the special game start prizes from being won, A lottery is performed so that one or two or more types of prizes can be won simultaneously from the prizes to be selected, or lottery is performed so that none of the prizes is won, and the result of the lottery is used as the lottery result. The lottery means (101, TBL11 to TBL13) and the winning result of the special game start prize are held as a carry-over game period after winning one of the special game start prizes and then winning the special game start prize. The lottery result holding means (101, S112a, S112j), and when the lottery result indicates winning of any one of the prizes excluding the blocking prize based on the lottery result, the lottery result is Each display row (R1, R2, R3) is stopped so that one or more of the prizes indicating winning are won, and the result of the lottery is displayed for each prize. When the winning of any of the blocking prizes is indicated, the display columns (R1, R2, R3) are stopped so as to block all winnings of the special game start prize, and the lottery result is included in the prizes. Display row stop means (101, S109) for stopping each of the display rows (R1, R2, R3) so as not to win any of the awards when winning of any prize is not indicated; When winning one of the special game start prizes in the normal game, the game type is shifted from the normal game to the special game corresponding to the special game start prize type, and a special game end condition corresponding to the special game And a game management means (101) for continuing the special game until is satisfied, and the lottery means (101, TBL11 to TBL13) In the regular game other than the regular game, one of the blocking prizes and at least one special game start prize is won at the same time, or the at least one special game start prize is selected as an individual prize. For each type of the special game start award, the probability of winning the special game start award that is the target of the simultaneous win and the special game start award that is the target of the individual win The lottery is executed so that the total probability of winning is constant, and in the regular game during the carryover game period, the lottery result holding means (101, S112a, S112j) wins from the prize to be the lottery target The lottery will be conducted with the exception of the special game start prize held as a lottery, and the lottery will not be won in any of the prizes. The at least one type of the special game that is the target of the individual winning by further including a probability adjusting means that can change the probability of winning one of the blocking prizes that are the target of the simultaneous winning. The probability of winning only the starting prize is adjustable.

According to this invention, the sum of the probability of winning the special game start prize that is the target of simultaneous winning and the probability of winning the special game start prize that is the target of individual winning is constant for each type of special game start prize. Since the lottery is executed, the special game is changed by changing the probability that at least one of the small role award or the replay award and the special game start prize are won simultaneously in the base game other than the carryover game period. The probability of winning only the start prize varies, and as a result, the probability of winning the special game start prize can be adjusted.
Furthermore, the lottery means performs a lottery by excluding the special game start prize held as the lottery result won by the lottery result holding means from the prizes for the lottery in the base game during the carryover game period. In addition, it is possible to make a lottery so as not to win any prize among the prizes, and the probability of not winning any prize among the prizes other than the carryover game period. In comparison with the normal game, the probability assigned to the excluded special game start prize may be increased. In this case, in the normal game during the carryover game period, the probability of losing is in a trade-off relationship with respect to the probability that at least one kind of prize among the blocking prizes is won. By changing the probability of winning at least one of the prevention prizes, the probability of losing will change and the lottery result will carry over the special game start prize, resulting in a special game start prize. It is possible to adjust the probability of

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 have 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 and radial frames extending radially from the shaft portion. 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.

  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. 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.

<4-1: Slot Machine Game Method>
FIG. 5 is an explanatory diagram showing the flow of game medals in the game method of the slot machine 1 according to the embodiment of the present invention.
(1) Insertion Bet Processing A game in the slot machine 1 starts when a player inserts a game medal into the medal insertion slot 10 (insertion operation). In this embodiment, by inserting three game medals, the five pay lines L1 to L5 are activated (insert bet operation).
(2) Insertion credit processing When the player further inserts game medals, up to 50 game medals are stored in the storage device as credits. If the player inserts more game medals after the number of stored game medals reaches 50, the game medals are returned to the medal tray 40.
(3) Storage bet processing In order to start a game, a winning line is activated when the player presses the bet button 11 for a credit stored in the storage device in addition to the input operation (storage bet operation). The storage bet operation and the insertion bet operation are collectively referred to as a bet operation.

(4) Dividend credit processing When the player depresses the start lever 12, the rotation of the three reels R1 to R3 is started, and when the player depresses the stop buttons 13a to 13c, the reel corresponding to each stop button. R1 to R3 are stopped. When all the reels R1 to R3 are stopped, a winning combination is obtained when the predetermined symbol combination is aligned on the activated pay line (when the reel stop mode is in a predetermined state), ) Is given game value. When a game medal is awarded as a game value as a game value, the game medal is first stored as a credit in the storage device.

The

<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). In the slot machine 1, when a predetermined symbol combination is aligned on the activated pay line, a winning is made (when the reel stop mode is not in a predetermined state), and 15 coins are determined based on the number of payouts determined for each combination. There are a small role award in which a payout with the maximum medal is awarded, a start award for starting another type of game from the normal game, and a re-game award 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). Composed. Further, in the BB1 game and the BB2 game, the winning probabilities of the internal lottery for the small role prize may be different from each other, or the number of medals acquired as the end condition may be different from each other. In this embodiment, the game is exactly the same.

(2) 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).

(3) Small role award The small role A award (also referred to as a bell award) is a small role award with eight medals as a dividend, and a combination of “Bell-Bell-Bell” symbols (“Bell”). (Also called).
The small role B prize (also referred to as a cherry award) is a small role award that uses two medals as a dividend, and is composed of a combination of symbols “cherry-ANY-ANY” (also referred to as “cherry role”) as a role. The ANY indicates that any symbol may be used. The “cherry role” is awarded only when the “cherry” symbols of the left reel R1 are aligned on the winning line.
The small role C award is a small role award with a single medal as a payout, and is composed of a combination of symbols “Plum-Plum-Bell” as a role. The small role D award is a small role award in which one medal is a dividend, and is composed of a combination of symbols “Plum-Bell-Plum” as a role. The small role E award is a small role award with a single medal as a payout, and is composed of a combination of symbols of “bell-plum-plum” as a role.
The number of medals required to start one game is “3”, but the payout of the small role C prize to the small role E prize is one. However, as in the case of losing, the number of medals held by the player decreases.

(4) 100% retractable design The “Plum” design and the “Bell” design, as shown in the design layout of FIG. The interval between symbols up to “a” symbol, and the interval between symbols between a “bell” symbol and the next “bell” symbol, are both within 5 symbols (5 frames). For example, in the middle reel, the “bell” symbol with symbol number PN = 12 is separated from the “bell” symbol with symbol number PN = 7 by five 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, by arranging the “plum” symbol and the “bell” symbol so as to be within 5 frames, no matter what timing the player operates the reel stop buttons 13a, 13b, 13c, The symbol can be drawn on the winning line and stopped.

  In each reel, symbols arranged within one frame number larger than the maximum number of frames to be drawn are stopped by drawing the symbol onto the winning line even if the reel stop buttons 13a, 13b, 13c are operated at an arbitrary timing. It becomes possible. Such a “plum” symbol and a “bell” symbol are referred to as 100% drawable symbols or 100% winning symbols. In this example, the “Red 7” symbols arranged on the middle reel and the right reel are also 100% retractable symbols.

  Furthermore, a cherry symbol to be arranged is arranged on the left reel. The Cherry Prize is awarded when the “Cherry” symbol stops on the upper, middle, or lower stage on the left reel. For this reason, the “cherry” symbol can be stopped at any one of the upper, middle, and lower stages by pulling in four frames regardless of the timing of operating the reel stop button 13a. Therefore, the “cherry” symbol is a 100% retractable symbol.

  On the other hand, the “red 7” symbol and the “white 7” symbol on the left reel are not 100% retractable symbols. For example, it is assumed that the variable display of the middle reel and the right reel is stopped, and “red 7” symbols are aligned in the lower stage. In this case, if the left reel stop button 13a is operated at the timing when the plum symbol with the symbol number PN = 7 is positioned in the middle, the left reel is used to draw the “white 7” symbol with the symbol number PN = 11 down. It is necessary to advance the left reel by 6 frames in order to draw the “red 7” symbol of symbol number PN = 12. Therefore, the maximum number of frames to be drawn exceeds 4 frames. Therefore, the “red 7” symbol and the “white 7” symbol on the left reel are not 100% retractable symbols.

  However, when the winning flag for the BB1 prize or the winning flag for the BB2 prize is valid independently, when the player first operates the left reel stop button 13a, the player may be awarded 100% in the BB1 prize or the BB2 prize. Is possible. This is because it is possible to stop the “Red 7” symbol and the “White 7” symbol at any of the upper, middle and lower levels of the stop display position of the left reel regardless of the timing of the stop operation. is there.

<4-3: Explanation of various games in the slot machine>
FIG. 7 is an explanatory diagram showing the transition of the game state performed in the slot machine 1. The game state transition is performed by the CPU 101 executing a control program. In the normal game, the BB game, and the RT game, the probability that each lottery category is selected in the internal lottery is different.

(1) Normal game (A)
In the internal lottery in the normal game, one of a plurality of lottery categories is selected. Each of the plurality of lottery sections is associated with one or more prizes. In the present embodiment, the BB1 prize or the BB2 prize is associated with all the lottery sections (see FIG. 10). Therefore, the BB1 prize or the BB2 prize is always won in the internal lottery of the first normal game.

(2) Carry-over period in normal games (Am1, Am2)
If the BB1 award is won by an internal lottery during the normal game, and the “red 7 role” is not aligned on the winning line in the game and the game is non-winning, the transition to the carry-over period of the BB1 award in the normal game (Am1 ), Carry on the BB1 prize winning flag until winning the BB1 prize. Also, if the BB2 is won by an internal lottery during the normal game, and the “white 7 role” is not lined up on the winning line in the game and the game is not won, the BB2 award carry-over period in the normal game is entered ( Am2).

(3) Start and end of BB game (B)
When “red 7 role” or “white 7 role” is established on the winning line and the BB1 award or BB2 award is won, the game type shifts from the next game to the BB game. The BB game ends when the acquired number of games during the BB game exceeds the specified number. This is the BB game end condition. In this example, the prescribed number is set to 465 in both the BB1 game that starts when “Red 7 role” is established and the BB1 game that starts after “White 7 role” is established. It should be noted that the BB2 game that starts when “White 7 role” is established may have a prescribed number of 185. In the BB game, the number of medals required to start the game is set to one. In addition, the number of bells to be paid out is 15.

(4) Start and end of RT game (C)
When the BB1 game or the BB2 game ends, the process shifts to the RT game (C). In the RT game, the probability that the lottery category to which the re-game prize belongs is selected in the internal lottery is different from that in the normal game. In this example, the RT game is smaller than the normal game. Then, as the probability that the lottery section is selected decreases, the probability that the lottery section assigned only with the BB1 prize increases. The RT game end condition is to win a BB prize or to pass a predetermined number of games. In this example, the maximum number of RT games is 30 games and 10 games. When the BB1 prize winning flag is carried over, the game is 30 games, while when the BB2 prize winning flag is carried over, the game is 10 games.

(5) Carry-over period in RT game (Cm1, Cm2)
If the BB1 prize is won by an internal lottery during the RT game, and the "Red 7 role" is not aligned on the winning line in the game and the prize is not won, the BB1 prize carryover period in the RT game is entered (Cm1 ), Carry on the BB1 prize winning flag until winning the BB1 prize. In addition, when the BB2 is won by an internal lottery during the RT game, and the “white 7 role” is not aligned on the winning line in the game and the player has not won, the BB2 award carryover period in the RT game is entered ( RT2). In the internal lottery of the RT game, a BB1 prize or a BB2 prize is assigned to all lottery sections (see FIG. 10). For this reason, in the internal lottery of the first RT game, the BB1 prize or the BB2 prize is always won. If the BB1 prize or BB2 prize is not won in the first RT game, the carry-over period (Cm1, Cm2) is entered.

  In the slot machine 1, the game type is managed by the game type flag shown in FIG. Bit b0 of the game type data is a BB1 in-game flag. When the BB1 in-game flag is set to “1”, it indicates that the BB1 game is in progress. Bit b1 of the game type data is a BB2 in-game flag. When the BB2 in-game flag is set to “1”, it indicates that the BB2 game is in progress. Bit b2 of the game type data is an RT game flag. When the RT game in-progress flag is set to “1”, it indicates that the RT game is in progress.

Bit b3 of the game type data is a BB1 award carry-over flag during the normal game. When the flag is set to “1”, it indicates that the BB1 award is carried over during the normal game. Bit b4 of the game type data is a BB2 award carryover flag during the normal game. When the flag is set to “1”, it indicates that the BB2 prize is carried over during the normal game. Bit b5 of the game type data is a BB1 award carryover flag during the RT game. When the flag is set to “1”, it indicates that the BB1 prize is carried over during the RT game. Bit b6 of the game type data is a BB2 award carryover flag during the RT game. When the flag is set to “1”, it indicates that the BB2 prize is carried over during the RT game.
Hereinafter, when it is not necessary to distinguish between the BB1 in-game flag and the BB2 in-game flag, they are simply referred to as a 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 makes it 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). Using the selected prize lottery table, the CPU 101 determines which numerical range set for each lottery category on the prize lottery table the acquired random number value belongs to, and the prize corresponding to the lottery category is determined. A winning flag is set (S105). Next, the CPU 101 outputs the RT count number and the 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 stop link table is data specifying a stop data table used for stop control.

  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 motor sequentially or simultaneously to rotate the three reels (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.

  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, there are other methods after a predetermined number of steps have elapsed from the start of reel rotation or a predetermined time has elapsed since the start of reel rotation (predetermined number of interruptions). After generation)), a method of assuming that a constant rotational speed has been reached by outputting pulses at regular intervals to the stepping motor, or a predetermined time after the start of reel rotation, or a predetermined time after the start of reel rotation ( 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 reel that was not performed is automatically stopped.

  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, the symbol corresponding to the symbol position designated by the advance frame number can be displayed at the middle display position with the symbol 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 maximum number of advance frames in the slot machine 1 is “4”.

  Next, when all the reels are stopped, the CPU 101 determines whether a winning combination is established based on the symbol positions on the effective winning line (whether or not the reel stop mode is in a predetermined state). (S110), and when winning, a game value set for each combination is given. Next, the CPU 101 performs a game end determination process (S111). In this game end determination process, for example, in the BB game, it is determined whether or not the number of acquired sheets in the BB game exceeds 465 as the end condition. Further, in the RT game, it is determined as an end condition that a BB prize has been won or a predetermined number of games have passed. When these end conditions are satisfied, the respective in-game flags (BB1 in-game flag, BB2 in-game flag, RT in-game flag, carryover period flag in the RT game) are cleared and the game 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 small role award or replay award that the flag cannot carry over, the winning flag is cleared regardless of whether it 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 a prize, the prohibition of the bet operation performed in step S102 is canceled (S114) so that a game medal can be inserted or the input of the bet button 11 can be accepted, and in preparation for the start of the next game. 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 base game, selection probabilities for determining any of the lottery categories from “lottery category 1” to “lottery category 11” by internal lottery are “3800/65536”, “200/65536”, “10148 /”, respectively. 65536 "," 6000/65536 "," 10148/65536 "," 6000/65536 "," 10149/65536 "," 6000/65536 "," 6017/65536 "," 6000/65536 "," 374/65536 " Is set, and an internal lottery is performed using the prize lottery table TBL11 storing data indicating the selection probability, 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 the top storage area of the prize lottery table TBL11, lottery category data “3800” of “lottery category 1” is stored. When the acquired random number value belongs to the range of 0 to 3799, the lottery category 1 is selected, and the BB1 prize and the Bell prize are won at the same time.
Further, the lottery category data of “lottery category 2” is “200”. When the acquired random number value belongs to the range of 3800 to 3999, the lottery category 2 is selected, and the BB1 prize and the cherry prize are won at the same time.
Further, the lottery category data of “lottery category 3” is “10148”. When the acquired random number value belongs to the range of 4000 to 14247, the lottery category 3 is selected, and the BB2 prize and the small part C prize are won simultaneously.
Further, the lottery category data of “lottery category 4” is “6000”. When the acquired random number value belongs to the range of 14148 to 20147, the lottery category 4 is selected, and the BB1 prize and the small part C prize are won simultaneously.
Further, the lottery category data of “lottery category 5” is “10148”. When the acquired random number value is in the range of 20144 to 30295, the lottery category 5 is selected, and the BB2 prize and the small part D prize are won simultaneously.
Further, the lottery category data of “lottery category 6” is “6000”. When the acquired random number value belongs to the range of 30296 to 36295, the lottery category 6 is selected, and the BB1 prize and the small part D prize are won simultaneously.
In addition, the lottery category data of “lottery category 7” is “10149”. When the acquired random number value belongs to the range of 36296 to 46444, the lottery category 7 is selected, and the BB2 prize and the small part E prize are won simultaneously.
Further, the lottery category data of “lottery category 8” is “6000”. When the acquired random number value belongs to the range of 46445 to 52445, the lottery section 8 is selected, and the BB2 prize and the small part E prize are won simultaneously.
Further, the lottery category data of “lottery category 9” is “6717”. When the acquired random number value belongs to the range of 52445 to 59161, the lottery category 9 is selected, and the BB2 prize and the replay prize are won at the same time.
Further, the lottery category data of “lottery category 10” is “6000”. When the acquired random number value belongs to the range of 59162 to 65161, the lottery category 10 is selected, and the BB1 prize and the replay prize are won simultaneously.
Further, the lottery category data of “lottery category 11” is “374”. If the acquired random number value belongs to the range of 65162 to 65536, the lottery category 11 is selected and only the BB1 prize is won.

Here, the product of the probability that the lottery category to which each of the small role prizes is assigned is selected by lottery and the number of medals given to the small role prize associated with the lottery category is set as the expected value of each lottery category. Sometimes, it is an important technical factor that the sum of expected values is smaller than the number of reference medals required to start one game.
In the slot machine 1, most of the payout of medals is executed in the BB game. Therefore, in the normal game, it is necessary to reduce the medals held by the player. However, in the present embodiment, stop control is performed in which a BB prize is assigned to all lottery sections, and a small role prize is given priority over a BB prize. For this reason, in order for a game to be established, it is necessary to reduce the number of medals even when winning the small role prize. By determining the probability and the payout as described above, the game of the slot machine 1 is established.

  The result of the internal lottery is stored by a winning flag shown in FIG. Bit b0 of the winning flag indicates a BB1 winning flag, bit b1 indicates a BB2 winning flag, bit b2 indicates a bell winning flag, and bit b3 indicates a cherry winning flag. Bit b4 indicates a replay winning flag, bit b5 indicates a small combination C winning flag, bit b6 indicates a small combination D winning flag, and bit b7 indicates a small combination E winning flag. When the flag is set to “1”, the winning of the corresponding prize is shown. Further, if the corresponding prize cannot be won in the game won by the internal lottery, the BB1 winning flag and the BB2 winning flag are carried over with the winning flag set in the next game until winning. 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 it is “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 BB game in-progress flag to determine whether or not the BB game is in progress (S104a). If it is determined that the BB game is in progress, the award lottery table TBL13 is selected (S104a1). Then, the association between the lottery sections 1 to 11 and the winning prize is set in the association pattern CP5 shown in FIG.

  If it is determined in step 104a that the BB game is not being played, it is determined whether the RT game is being played with reference to the RT game flag (S104b). If it is determined that the RT game is being played, the prize lottery table TBL12 is stored. Select (S104b1). Further, the CPU 101 refers to the flag to determine whether or not it is a carry-over period during the RT game (S104d). If it is the carry-over period during the RT game, the association between the lottery sections 1 to 11 and the winning prize is set in the association pattern CP4 shown in FIG. 10B (S104d1), and the normal period during the RT game is set. If there is, the association between the lottery sections 1 to 11 and the winning prize is set in the association pattern CP3 shown in FIG. 10B (S104d2).

Next, when it is determined in step 104b that the RT game is not being played, the prize lottery table TBL11 is selected (S104b2). Further, the CPU 101 refers to the flag to determine whether or not it is a carry-over period during the normal game (S104e). In the case of the carry-over period during the normal game, the association between the lottery categories 1 to 11 and the winning prize is set in the association pattern CP2 shown in FIG. 10B (S104e1), If there is, the association between the lottery sections 1 to 11 and the winning prize is set in the association pattern CP1 shown in FIG. 10B (S104e2).
The association patterns CP1 to CP5 described above are realized by a winning flag set process described below.

<5-3: Winning flag set processing>
12 to 14 are flowcharts 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 award lottery table corresponding to the acquired random value and 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. This is because during the carry-over period, the winning flag for the BB1 prize or the BB2 prize is not cleared in the winning flag clear process in step S112. If the winning flag carried over from the previous game remains without being cleared, it does not have to be reset in the winning flag setting process, but the case where the winning flag is set every time in the winning flag setting process will be described as an example. .

  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 carryover period is further increased. If it is a carryover period, the bell prize winning flag is set (S105a2), while if it is not a carryover period, a BB1 prize winning flag and a bell prize winning flag are set (S105a3).

  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 (S105b). It is determined whether or not it is a period (S105b1). If it is a carryover period, a cherry prize winning flag is set (S105b2). If it is not a carryover period, a BB1 prize winning flag and a cherry prize winning flag are set (S105b3). .

  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 (S105c). It is determined whether or not it is a period (S105c1). If it is a carryover period, a small part C prize winning flag is set (S105c2), while if it is not a carryover period, a BB2 prize winning flag and a small part C prize winning flag are set. (S105c3).

  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 (S105d). It is determined whether or not it is a period (S105d1). If it is a carryover period, a small part C prize winning flag is set (S105d2), while if it is not a carryover period, a BB1 prize winning flag and a small part C prize winning flag are set. (S105d3).

  Next, the CPU 101 determines whether or not the acquired random number value belongs to the “lottery category 5” range of the prize lottery table (S105e). It is determined whether or not it is a period (S105e1). If it is a carryover period, a small role D prize winning flag is set (S105e2). If it is not a carryover period, a BB2 prize winning flag and a small role D prize winning flag are set. (S105e3).

  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 (S105f). It is determined whether or not it is a period (S105f1). If it is a carryover period, a small part D prize winning flag is set (S105f2), while if it is not a carryover period, a BB1 prize winning flag and a small part D prize winning flag are set. (S105f3).

  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 (S105g). It is determined whether or not it is a period (S105g1). If it is a carryover period, a small role E prize winning flag is set (S105g2). If it is not a carryover period, a BB2 prize winning flag and a small role E prize winning flag are set. (S105g3).

  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 (S105h). It is determined whether or not it is a period (S105h1). If it is a carryover period, a small role E prize winning flag is set (S105h2), while if it is not a carryover period, a BB1 prize winning flag and a small role E prize winning flag are set. (S105h3).

  Next, the CPU 101 determines whether or not the acquired random number value belongs to the “lottery category 9” range of the prize lottery table (S105i). It is determined whether or not it is a period (S105i1). If it is a carryover period, a re-game prize winning flag is set (S105i2), while if it is not a carry-over period, a BB2 prize winning flag and a re-game prize winning flag are set ( S105i3).

  Next, the CPU 101 determines whether or not the acquired random number value belongs to the “lottery category 10” range of the prize lottery table (S105j). It is determined whether or not it is a period (S105j1). If it is a carryover period, a re-game prize winning flag is set (S105j2), while if it is not a carry-over period, a BB1 prize winning flag and a re-game prize winning flag are set ( S105j3).

Next, the CPU 101 determines whether or not the acquired random number value belongs to the “lottery category 11” range of the prize lottery table (S105k). It is determined whether or not it is a period (S105k1). If it is a carryover period, the process ends. On the other hand, if it is not a carryover period, a BB1 prize winning flag is set (S105k2).
Note that in the BB game, only the lottery sections 1 and 2 are provided, so that the winning flag setting process may be stopped when the process of the lottery section 2 is completed.

<5-4: Stop link table selection process>
In the present embodiment, as shown in FIG. 15, stop link tables TBL21 to TBL29 divided for each prize are stored in the ROM 104. In this stop link table selection processing, stop link tables TBL21 to TBL28 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 selected. Stop display while selecting sequentially. The stop link table is classified for each prize to be a lottery target of the internal lottery. The stop link tables TBL21 to TBL28 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 depending on which of the display positions of the upper, middle, and lower stages the symbols constituting the prize are displayed.

FIG. 16 is a flowchart showing the contents of the stop link table selection process in step S106. First, the CPU 101 determines whether or not the bell winning flag is set (S106a). If it is determined that the bell winning flag is set, the CPU 101 selects the bell stop link table TBL21 (S106a1) and ends the processing. .
Next, the CPU 101 determines whether or not the cherry winning flag is set (S106b). If it is determined that the cherry winning flag is set, the CPU 101 selects the cherry stop link table TBL22 (S106b1) and ends the processing. To do.
Next, the CPU 101 determines whether or not the small role C winning flag is set (S106c). If it is determined that the small role C winning flag is set, the CPU 101 selects the stop link table TBL23 for the small role C (S106c1). This process ends.
Next, the CPU 101 determines whether or not the small role D winning flag is set (S106d). If it is determined that the small role D winning flag is set, the CPU 101 selects the stop link table TBL24 for the small role D (S106d1). This process ends.
Next, the CPU 101 determines whether or not the small role E winning flag is set (S106e). If it is determined that the small role E winning flag is set, the CPU 101 selects the stop link table TBL25 for the small role E (S106e1). This process ends.
Next, the CPU 101 determines whether or not the re-game winning flag is set (S106f). If it is determined that the re-game winning flag is set, the CPU 101 selects the re-game stop link table TBL26 (S106f1) and performs this process. Exit.

  Next, the CPU 101 determines whether or not the BB1 winning flag is set (S106g). If it is determined that the BB1 winning flag is set, the CPU 101 selects the stop link table TBL27 for BB1 (S106g1) and is not set. Is determined, the stop link table TBL28 for BB2 is selected.

  In the present embodiment, as shown in FIG. 10B, in the normal period of the normal game and the RT game, when the lottery divisions 1 to 10 are won, the small role prize or the replay prize and the BB prize are won simultaneously. In addition, during the carryover period of the normal game and the RT game, when the lottery divisions 1 to 10 are won, the winning combination flag of the BB prize is carried over at the same time as the small role prize or the replay prize is won. As described above, when the winning flag of the small role prize or the replay prize and the winning flag of the BB prize are simultaneously valid, it becomes a problem which priority is drawn to the winning line. In the present embodiment, the small role prize or the replay prize is drawn into the winning line in preference to the BB prize. Therefore, when the winning flag for the small role prize or the replay prize and the winning flag for the BB prize are valid at the same time, the stop link table for the BB is not selected and the BB prize is not won. In other words, the BB prize can be won only in a game in which the winning flag for only the BB prize is valid.

<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 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. 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 in the upper display position, the winning line L1 if it can be displayed in the middle display position, or the winning line L3 if it can be displayed in 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 where the stop operation has been performed, 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 passed 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 prize that allows 100% winning (S109z). Here, if it is determined that 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 associated with the position of each reel stopped 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 dividend is awarded if it is a small winning prize.

  First, the CPU 101 creates a winning determination table from the symbol positions of all the stopped 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 bell prize has been won (S110c). If it is determined that a prize has been won, a payout process for eight medals is performed (S110c1). Subsequently, it is determined whether or not a cherry 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 C to E prize has been won (S110e). If it is determined that the prize has been won, a payout process for one medal 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 BB1 prize has been won (S110f). If it is determined that the BB1 prize has been won, the BB carryover game flag is cleared and the BB game flag corresponding to the prize is set (S110f1). ), The acquired number counter is cleared (S110f2).

  Next, the CPU 101 determines whether or not the BB2 prize has been won (S110g). If it is determined that the BB2 prize has been won, the CPU 101 clears the BB carryover game flag and sets the BB game flag according to the prize (S110g1). ), The acquired number counter is cleared (S110g2).

<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 clear process, a 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 is carried over to the next game without being cleared. Do things.

  First, the CPU 101 clears each winning flag in one game regardless of winning the re-game winning flag, the bell winning flag, the cherry winning flag, and the small role C to E winning flags (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 a BB1 prize has been won (S112c). When it is determined that “Red 7 role” has been established and 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 won, the BB carryover game flag is set (S112j), the next game is changed to the BB carryover game, and the process ends.

<6: Summary>
According to the slot machine 1 of the present embodiment, the first base game, that is, the base game immediately after the power is turned on, does not carry the winning flag of the BB prize because there is no previous game. In addition, since the first RT game is executed immediately after the end of the BB game, the BB prize winning flag is not carried over even in the game.
Therefore, the first normal game and the first RT game are in a normal period. However, since the BB prize is assigned to all the lottery categories 1 to 11 in the normal period of the normal game and the RT game, unless the BB prize is won in the first normal game and the first RT game, Be sure to move to the carryover period.
In the normal game and the RT game, the stop control is executed so that the replay prize, the bell prize, the cherry prize, and the small part C prize to the small part E prize are given priority over the BB prize. In the period, the BB prize can be awarded only when the lottery section 11 is selected.

  FIG. 21 shows an example of game state transition. In this example, in the first normal game, lottery section 4 is selected by internal lottery. As a result, BB2 prize and small part C prize are won. The small role C award is composed of 100% winning symbols, and in the stop control, the small role C award is drawn in preference to the BB2 award, so the small role C award is won. Therefore, the winning flag of the BB2 award is carried over to the next game, and the transition from the second game to the normal game carry-over period is made.

  In this example, in the 105th game, lottery section 11 is selected by internal lottery. In this case, the lottery result of the game is lost, but the winning flag of the BB2 prize is carried over from the previous game. That is, in the 105th game, only the winning flag for the BB2 prize is valid, and the winning flag for the small role prize and the replay prize that are prioritized in the stop control over the BB2 prize is invalidated. As a result, it becomes possible to win the BB2 prize.

  If the total number of symbol stop display positions and the maximum number of draw-in frames is the specified number of frames, the symbols placed within the specified number of frames will stop regardless of the timing at which the player operates the reel stop button. It can be pulled into the display position. In the present embodiment, there are three symbol display positions, upper, middle, and lower, and the maximum number of frames to be drawn is 4, so the specific number of frames is 7 frames. In the left reel, the “white 7” symbols constituting the BB2 award are arranged 7 frames apart. Therefore, the “white 7” symbol can be pulled into any one of the upper, middle, and lower stages and stopped regardless of the timing at which the left reel stop button 13a is operated. The “red 7” symbol on the middle reel and the right reel is a 100% winning symbol because it is arranged within five frames. Therefore, if the stop operation is executed so as to stop the left reel first, the BB2 prize can be always won.

  On the other hand, when the middle reel or the right reel is first stopped, it is not always possible to win the BB2 prize. For example, in the middle reel and the right reel, when the “red 7” symbol is stopped on the upper stage, the “BB 7” prize is not won unless the “white 7” symbol is stopped on the upper stage. For example, when the “white 7” symbol of symbol number PN = 4 is positioned at the symbol display position in the middle stage at the timing when the reel stop button 13a is operated, the BB2 prize is not won.

  Here, the payout of the small role C prize, the small role D prize, and the small role E prize is one medal, and the payout of the cherry prize is two medals. The small role C prize, the small role D prize, and the small role E prize are always won if the lottery divisions 3 to 8 are won by internal lottery. Since the number of medals required for starting the game is three, the number of medals decreases even if these small role prizes are won.

  When the BB2 prize is won in the 105th game, the BB2 game is started from the 106th game. In this example, in the 150th game, the number of acquired game sheets reaches a predetermined number, and the BB2 game ends.

  When the BB2 game ends, the next game is shifted to the RT game. In this example, the 151st game is a normal period of the RT game. In the RT game, the width of the lottery section 10 decreases from 6000 to 2277 and the width of the lottery section 11 increases from 374 to 4097, as shown in FIG. Therefore, in the RT game, the lottery section 11 is easily selected as compared with the normal game. In the example shown in FIG. 10A, it is about 11 times.

  In this example, in the 151st game which is the first RT game, the lottery category 1 is selected by the internal lottery, and the BB1 prize and the Bell prize are won. Since the symbols composing the Bell Award are drawn into the winning line in preference to the symbols composing the BB1 Award, and the symbols composing the Bell Award are 100% winning symbols, they will not win the BB1 Award. Therefore, the winning flag of the BB1 prize is carried over to the next game.

  The RT game end condition is to win a BB prize or to reach a predetermined number of games. In this embodiment, the maximum number of RT games is 30 when the BB1 award is carried over, and 10 games when the BB2 award is carried over. During the carryover period, if the lottery category 11 is selected in the internal lottery, the game is lost, and only the winning flag for the BB prize is valid. In this case, by drawing the symbols constituting the small role award and the replay award to the winning line, the winning of the BB prize is not hindered, and it is possible to win the BB prize. As described above, the probability that the lottery category 11 in which the BB prize can be won is selected in the internal lottery is higher in the RT game than in the normal game, so that it is possible to win the BB prize during the RT game. High nature. Therefore, it is possible to continuously execute the BB game via the RT game, such as BB game → RT game → BB game. The number of times of continuous transition to the BB game via the RT game is determined according to the product of the maximum number of RT games and the probability that the lottery category 11 is selected in the internal lottery.

  As described above, the maximum number of RT games is determined according to the type of the winning flag carried over. Whether the BB1 prize winning flag is carried over or the BB2 prize winning flag is carried over depends on which lottery category is selected by lottery in the first RT game. Here, a bell prize and a BB1 prize are assigned to the lottery category 1. On the other hand, there is no lottery division to which the bell prize and the BB2 prize are assigned. Therefore, if the player wins the Bell Prize in the first RT game, the player can know that the maximum number of RT games is 30 games. In addition, a cherry prize and a BB1 prize are assigned to the lottery section 2, and there is no lottery section to which the cherry prize and the BB2 prize are assigned. Therefore, if the Cherry Prize is won in the first RT game, the player can know that the maximum number of RT games is 30 games. In this way, by providing a small role award or a replay award that is paired only with a certain BB award among a plurality of types of BB awards, the type of BB award and the maximum of RT games can be obtained without using a special device. The number can be notified to the player.

In this case, it is preferable to notify the player who is advantageous to the player who has a large prescribed number of BB games or a large number of RT games.
If the bell prize and the BB2 prize are associated with the lottery category 1, the player is notified that the BB2 prize has a small prescribed number in the BB game and that the maximum number of RT games is 10 games. The Then, the player plays the game with an expectation that the game can be shifted to the BB2 game up to 10 games, but the expectation is lost in 11 games. After that, if the player knows that the prescribed number in the BB game is small even when winning the BB prize, the player loses his willingness to continue.
However, if the BB1 award is informed, the player can have an expectation of up to 30 games. Even if the BB award cannot be won, if the player knows that the prescribed number of BB games to start next is large, Because he is motivated to continue.

  In this example, the BB1 prize is won in the 165th game, and the BB1 game is from the 166th game to the 220th game. And it transfers to RT game again from the 221nd game. Then, the lottery category 7 is selected in the internal lottery of the game, and the small role E prize and the BB2 prize are won. In this case, since the winning flag of the BB2 prize is carried over, the maximum number of RT games is 10. In this example, the lottery division 11 is not selected in the 10th game from the 221nd to the 230th game, and the BB2 prize cannot be won during this period. For this reason, in the 230th game, the game shifts from the RT game to the normal game.

  As described above, the slot machine 1 has the following characteristics. First, the BB prize is assigned to all lottery sections so that the BB prize winning flag is always valid in the base game. Secondly, the probability of selecting the lottery category 10 to which the re-game prize is assigned in the RT game is reduced as compared with the normal game, and the lottery category 11 to which only the BB prize is assigned is reduced. Control that the probability of selection increases. Third, the small role award and the replay award were controlled to be drawn in preference to the BB award. Fourth, in the RT game, control is performed so that the game shifts to the BB game when the BB prize is won before the predetermined number of games elapses, and shifts to the normal game when the predetermined number of games elapses. Fifth, the small role C award to the small role E award in which one less than the number of medals to be inserted to start the game is paid. Since these technical elements are closely related in an organic manner, the slot machine 1 has the following effects.

More and more, so-called stock out does not occur like conventional stock machines. That is, in the conventional stock machine, even when the lottery for releasing the stocked BB prize is won during the period from when the slot machine is turned on until the BB prize is won in the internal lottery, the BB prize can be won. could not. However, according to the present embodiment, as described above, since the winning flag of the BB prize is always valid, it is possible to reliably prevent the stock from running out.
Furthermore, in the stock machine, the lottery for releasing the stock is executed separately from the internal lottery. However, in this embodiment, the BB game can be continued only by the internal lottery.
Moreover, according to the present embodiment, the BB game and the RT game can be looped, so that the BB prize can be won a plurality of times in a short time. Thereby, it is possible to give a wave to the payout of medals.
In addition. In the conventional stock machine, the stock is released at the end of the RT game, but when the so-called stock runs out, it is not possible to shift to the BB game. If the RT game period is lengthened to prevent this, the bonus game does not continue in a short time. On the other hand, if the RT game period is shortened and the probability of winning the BB prize is increased, the bonus game is too continuous and the payout increases. On the other hand, in this embodiment, since the winning flag of the BB prize is always valid, there is a possibility that the bonus game can be continuously executed by looping the BB game and the RT game, and the payout rate Can be adjusted.

<7: Modification>
The present invention is not limited to the above-described embodiments, and for example, the following modifications are possible.
(1) In the embodiment described above, the BB1 award and the BB2 award are 100% winning symbols for a part of the symbols constituting the award (middle reel and right reel), but the left reel is not a 100% winning symbol. It was. On the other hand, the BB prize can be awarded only when the lottery section associated with only the BB prize is selected in the internal lottery. In the normal game, such a lottery section is selected. Is rare.
Therefore, when the lottery category associated with only the BB prize is selected by internal lottery, this may be notified to the player. For example, notification information indicating that the liquid crystal display device 30 has been won may be displayed. Note that the notification means is not limited to display of an image, and may be notification of a tactile sensation by a vibrator. In short, any means may be used as long as the notification information can be transmitted so that the player can recognize it.

(2) For at least one BB award among the plurality of BB awards, all the symbols constituting the award may be 100% winning symbols. The BB prize can be awarded only when a lottery section associated with only the BB prize is selected in the internal lottery, but such a lottery section is rarely selected in a normal game. It is. If the BB award is a 100% winning symbol, it is possible to reliably win the BB award in the game.

(3) In the embodiment described above, the middle stage (L1) may be excluded from the winning line in order to avoid an unfair win. In this case, in particular, it is possible to easily avoid the simultaneous winning of the cherry prize and the BB1 prize.

(4) In the above-described embodiment, the BB prize is assigned to all of the plurality of lottery divisions so that the BB prize is won 100% in the base game and the RT game. A lottery section that is not allowed may be provided. Also in this case, as in the above-described embodiment, it is possible to prevent the stock from running out and to continue the BB game only by the internal lottery. Furthermore, you may employ | adopt the symbol arrangement | positioning which has missed a small part prize.

(5) In the above-described embodiment, the symbols constituting the Bell Award are 100% winning symbols, so that even if both the BB1 Award and the Bell Award are won simultaneously, winning the BB1 Award is prevented. In this way, when the BB prize and the small role prize are won at the same time, the winning of the BB prize can be prevented.
For example, the small role award includes a small role award 1 that is awarded with “Red 7-Bell-Bell” and a small role award 2 that is awarded with “White 7-Bell-Bell”, and the bonus award is “Red 7”. It shall include the BB1 award winning “Red 7-Red 7” and the BB2 award winning “White 7-Red 7-Red 7”. Here, “red 7” and “white 7” of the left reel R1 are arranged so that the pull-in range becomes exclusive. That is, in the left reel R1, “red 7” and “white 7” are arranged at a distance of 7 frames or more in total, that is, 4 frames that are the maximum number of frames to be drawn and 3 frames that are the number of columns in the display row. Then, the small role award 1 and the BB2 award are assigned to the same lottery so that simultaneous winning is possible, and the small role award 2 and the BB1 award are assigned to the same lottery so that simultaneous winning is possible.
Here, it is assumed that the small role prize 1 and the BB2 prize are won simultaneously by the internal lottery, and the player operates in the order of the right reel stop button 13c → the middle reel stop button 13b → the left reel stop button 13a.
First, in the right reel R3, the bell is a 100% winning symbol, and the small role award is given priority, so the bell is drawn into the winning line.
Secondly, the bell is drawn into the winning line in the middle reel R2 as in the right reel R3.
Thirdly, since the winning of the small role prize has priority, the left reel R1 is controlled so that “red 7” is brought closer to the winning line. “Red 7” is stopped on the winning line when it can be withdrawn, but if “red 7” cannot be withdrawn even if the “red 7” is moved by the maximum number of frames to be drawn, it is not won.
In this way, it is possible to configure such that the stop control is not performed so as to win the small role prize and the bonus prize is not won.
In the normal game, the bonus winning probability is set to 100%. However, it may not be 100%. For example, a small prize may not be won simultaneously with the bonus prize. However, it is desirable that the winning probability of the small role prize is low. In this case, since the winning probability of the small role award that is not the target of simultaneous winning is low, it can be assigned to the probability that the small role award and the bonus award are simultaneously selected and the probability that the bonus award is the individual winning. As a result, it is possible to increase the fluctuation range of the probability of winning the small prize that is the target of simultaneous winning, so that the payout rate can be adjusted with a high degree of importance.

(6) In the above-described embodiment, the transition to the RT game is always performed after the end of the BB game, but the transition to the RT game is not necessarily required. For example, when the BB2 prize is won in the first game after the end of the BB game, the game may be shifted to the normal game instead of the RT game. Other conditions that do not shift to the RT game may be set as appropriate. If the probability that the conditions for not shifting to the RT game are met is lowered, the BB game can be continued with a high probability.

(7) The slot machine may be configured as follows.
The reels R1 to R3 do not have to rotate in one direction, and may rotate from top to bottom, or may rotate from bottom to top. Further, the rotation direction may change during rotation.
The reels R <b> 1 to R <b> 3 may start rotating at an opportunity other than the operation of the start lever 12. For example, the rotation of the reels R1 to R3 may be started when a predetermined time has elapsed since the bet operation was accepted or the bet operation was accepted.
The reels R1 to R3 may stop rotating at an opportunity other than the operation of the stop buttons 13a to 13c. For example, the rotation of the reels R1 to R3 may be stopped when a predetermined time has elapsed from the start of rotation.
The internal lottery may be executed by a method other than having a lottery section. That is, any lottery method may be used as long as the lottery can be performed at a target ratio. For example, an internal lottery may be executed by providing a lottery table in which the extracted value is associated with a prize to be won for a value randomly extracted from a certain range and referring to the lottery table.
Even if the stop control of the reels R <b> 1 to R <b> 3 is not a slip control directed in one direction, the symbols constituting the winning prize may be selectively stopped.
The bonus winning probability may be adjusted by changing the probability of the small role award.
The value given when winning a prize may be other than the game medium. For example, it may be a payout of merchandise, a specific music performance, a specific image, or an animation display.
There may be an award that stocks the number of medals according to the winning prize when winning the small role prize, and an award that pays out the number of stocked medals when winning.
Bonus awards may be won. For example, when one of the bonus prizes won in duplicate is won, the bonus game may be entered and the winning flags of other bonus prizes may be cleared. If one of the duplicate bonus awards is won, the bonus game is entered, but the winning flag of the other bonus awards remains, so that the other bonus awards can be won after the bonus game ends. Also good.
