Abstract

<P>PROBLEM TO BE SOLVED: To provide a slot machine, switchable between an advantageous game state and a disadvantageous game state. <P>SOLUTION: This slot machine can perform a first normal game and a second normal game. The first normal game performs lottery for a BB prize, while the second normal game does not perform lottery. When an MB prize is won, the transition of the game state from the first normal game to the second normal game occurs. In the second normal game, when the number of tokens acquired reaches a predetermined amount, the game state is returned to the first normal game. Since the first normal game and the second normal game have the same probability of winning a small prize, a game play cannot discriminate whether the current game state is the first ordinary game or the second normal game from the prize winning rate of the small prize. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

The present invention relates to a slot machine.

A slot machine generally includes three reels, three reel stop buttons corresponding to each reel, and a start lever for starting a game. When the player depresses the start lever, all the reels rotate at the same time, and each reel stops at the timing when the player depresses each reel stop button. Of the combinations of symbols arranged on the winning line in a state where the reels are stopped, a combination of symbols that gives a game value is called a role. When a combination of symbols composing a combination on the effective winning line is completed, a winning is made, and the player can obtain the number of medals corresponding to the winning combination. That is, when the state where the reels are stopped is a state (predetermined state) that is a combination of symbols constituting the winning combination, a prize is won, and a game value corresponding to the winning prize 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 shows a loss, even if the player operates the reel stop button at the timing when the symbol that constitutes a certain role has reached the valid winning line, the reel stop timing is delayed, The reels are controlled so that the symbols constituting the combination do not stop on the valid pay 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. However, if the operation timing of the reel stop button is significantly deviated, no prize will be awarded. In other words, in order for a player to win a prize, it is necessary to win a prize by an internal lottery and align the winning combination on an effective prize line.

The plurality of prizes include a start prize for switching the game state from the base game to another game, and a payout prize for giving a predetermined number of medals as a dividend. The start prize includes the BB prize, and the payout prize includes the watermelon prize with 15 medals and the 10 bell prize. When the BB prize is won in the internal lottery and the combination of symbols “7-7-7” is arranged, the BB prize is won, and the BB game is started with a high probability of lottery in the internal lottery of the payout prize from the next game. The As for the BB prize, even if the BB prize cannot be aligned on the winning line in the game won by the internal lottery and the prize is not won, the result of the internal lottery is carried over until the BB prize is won.

In addition, there are slot machines called so-called stock machines. In this type of slot machine, the reel control is executed so that even if the BB prize is won in the internal lottery and the BB prize is not won, the number of times the BB prize is won is stored and the predetermined condition is satisfied. Then, the reel stop control is executed so that the symbols constituting the BB prize are aligned on the winning line (Patent Document 1). In other words, in the game state of the conventional stock machine, the internal lottery of the BB prize is executed, but even if the BB prize is won in the internal lottery, the stock period in which the symbols are prohibited is executed, and the internal lottery of the BB prize is executed. In addition, it is roughly divided into release periods in which it is allowed to align the symbols constituting the BB prize.
JP 2000-210413 A

In the conventional stock machine, since the BB prize stocked during the release period is released, the BB prize is continuously awarded during the release period, and there is a problem that the wave of the ball is rough. That is, there are cases where a large amount of medals can be obtained in a short time, and even when playing for a long time, no big bonus can be enjoyed. That is, in the conventional stock machine, the winning of the BB prize is controlled regardless of the internal lottery in the current game. In this way, slot machines with a lot of medals coming and going can be mischievous, so the rules regarding the recognition of game machines and the type test, etc., revised in 2004, indicate the number of winning BB prizes. Cumulative memory was banned.

The present invention has been made in view of the above-described problems, and it is an object of the present invention to provide a slot machine capable of executing a game state advantageous to a player and an unfavorable game state and capable of gently controlling the wave of a ball. And

The present invention will be described below. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment. The slot machine according to the present invention comprises a display means (DP) capable of variable display, a start operation means (12) for a player to input an instruction to start the variable display, and an instruction to stop the variable display. Stop operation means (13a, 13b, 13c) for the player to input, and the stop mode on the winning line (L1 to L5) in a state where the variable display of the display means (DP) is stopped is predetermined. It is possible to execute a plurality of types of game states including a first normal game, a second normal game, and a special game by winning a prize in the case of a winning mode, giving a predetermined game value according to the winning prize. In the slot machine, the prize includes a small prize including a payout of a game medium as the game value to be given, and a start prize for changing a game state type as the game value to be given. In the first base game, a plurality of start prizes and a plurality of small part prizes including a second base game start prize for transferring the game state to the second base game and a special game start prize for transferring the game state to the special game. A lottery is executed as a lottery object, a lottery is executed for a start prize and a plurality of small part awards that do not include the special game start prize in the second base game, and a plurality of small part prizes are drawn in the special game. A lottery is executed as a target, lottery information indicating a lottery result is generated, and in each of the first normal game and the second normal game, the types of small bonuses to be selected are the same, and each of a plurality of small bonuses And the combined probability of the plurality of small role awards in the special game is the first normal game. And a lottery means (101, TBL11 to TBL18) for executing a lottery so as to be higher than the combined probability of a plurality of small role awards in the second normal game, and the lottery information for winning any one of the small role awards. When the player operates the stop operation means (13a, 13b, 13c) at a predetermined timing, when the stop mode of the display means (DP) becomes a winning mode corresponding to the small role prize, On the condition that the second normal game start prize is won by the payout means (101) for paying out the game medium corresponding to the prize and the lottery means (101, TBL11 to TBL18), the game state is changed from the next game. After shifting from the first base game to the second base game and winning the special game start prize, the player operates the stop operation means (1 3a, 13b, 13c) When the stop mode of the display means (DP) becomes the special game start prize winning mode by operating 3a, 13b, 13c), the game state is shifted from the first normal game to the special game from the next game State transition means (101, S110k, S110k1) and acquired quantity counting means (101 for generating an acquired quantity by cumulatively counting the number of game media paid out in each of the second normal game and the special game. , S111k, S111v) and game state return means (101, S111n, S111p) for returning the game state to the first normal game when the acquired quantity exceeds a predetermined quantity in each of the second normal game and the special game. , S111x, S111y).

According to the present invention, the special game has a higher prize combination probability than the first normal game and the second normal game. Since the special game start prize is drawn in the first normal game, the game state may shift from the first normal game to the special game, while the special game start prize is not drawn in the second normal game. There is no transition to a special game. That is, the first normal game is an advantageous game compared to the second normal game in terms of the possibility of shifting to the special game. In this way, providing the game state with an advantageous state and an unfavorable state is important in terms of improving the taste of the game. However, if the player senses whether the current game state is the first normal game or the second normal game, no one will play in the second normal game, and the operating rate of the slot machine will decrease. . According to the present invention, the lottery means has the same small prize for lottery in the first normal game and the second normal game. In addition, the lottery is executed so that the winning probabilities of the small prizes are almost equal. Here, “substantially equal” means that the winning probabilities are set in a range in which it is impossible to determine that there is a significant difference in the winning probabilities even if a statistical method is used. For example, the winning probability of the same type of small role award in the first normal game and the second normal game may be within 70% to 130% for the other when one is used as a reference.

Also, in the conventional slot machine, the number of times the BB prize is won in the past is stocked, and the variable display is controlled to be stopped so as to allow the BB prize to be awarded when the release period is advantageous to the player. Therefore, the game state is an alternative of whether to win the BB prize or not, and there is a tendency for the wave of appearance to become rough. On the other hand, in the slot machine according to the present invention, even if it is the first normal game advantageous to the player, it is not possible to shift to the special game unless winning the special game start prize lottery. The number of winnings per unit time of the special game start prize during the game can be controlled by setting the winning probability. Also, in the first normal game, the game state is changed from the next game on condition that a lottery of the second normal game start award that triggers the transition to the second normal game, which is disadvantageous to the player, is executed and won. Since the transition is made to the second normal game, the transition to the special game can be flexibly controlled. In addition, the second normal game ends when the acquired quantity exceeds a predetermined quantity, and the game state shifts to the first normal game. Assuming that the transition from the second normal game to the first normal game is performed by lottery, if a large number of slot machines are installed in the hall, the slot machine that continues to lose the lottery and wins in a short period of time will be elected to the first normal game. The returning slot machine comes out. That is, the disparity between the stands becomes large, making it difficult to operate with an average number of balls. In this regard, the slot machine according to the present invention forcibly shifts to the first normal game when the acquired quantity exceeds a predetermined quantity. Therefore, even if a plurality of slot machines are installed, the gap between the stands is reduced. It becomes possible.

Note that there may be a plurality of small role awards in the special game, and the types of the small role awards do not necessarily match the first normal game and the second normal game. For example, assume that a small role a, a small role award b, and a small role award c are adopted as a small role award of the first normal game, and their combined probability is X. In this case, only the small role a and the small role award b may be employed as the small role award of the special game, or the small role a, the small role award b, and the small role award d may be employed. The small role award, the small role award b, the small role award c, and the small role award d may be employed, or the small role award d and the small role award e may be employed. In short, when Y is the synthetic probability of the small role prize of the special game, X <Y may be satisfied.

Next, another slot machine according to the present invention includes a display means (DP) capable of variable display, a start operation means (12) for a player to input an instruction to start the variable display, and the variable Stop operation means (13a, 13b, 13c) for the player to input an instruction to stop the display, on the winning line (L1 to L5) in a state where the variable display of the display means (DP) is stopped A plurality of types of game states including a first normal game, a second normal game, and a special game, in which a prize is awarded when the stop mode is a predetermined prize mode, a predetermined game value is given according to the prize awarded The prize includes a small prize including a payout of a game medium as the game value to be given, and a start prize for changing a game state type as the game value to be given. A plurality of start prizes including a second normal game start prize for transferring the game state to the second normal game and a special game start prize for transferring the game state to the special game in the first normal game; A lottery is executed with a prize as a lottery object, a lottery is executed with a start prize and a plurality of small part awards not including the special game start prize in the second normal game as a lottery object, and a plurality of small roles are included in the special game. A lottery is executed with a prize as a lottery object, lottery information indicating a lottery result is generated, and in the first normal game and the second normal game, the types of small role prizes to be a lottery object are the same and a plurality of small roles When the probability of winning each of the prizes is substantially equal, and the total probability of winning each of the plurality of small prizes is defined as the combined probability, The lottery is executed so as to be higher than the combined probability of a plurality of small role awards in the base game and the second base game, and the second base game start award and the special game start award are next to the game won by the lottery. Lottery means for carrying over the winning lottery result and generating the lottery information together with the lottery result of the current game in the carry-over period from the game to the second base game and the game winning each of the special game start prizes 101, TBL11 to TBL18) and when the lottery information indicates winning of any of the small role prizes, the player operates the stop operation means (13a, 13b, 13c) at a predetermined timing to display the display means. When the stop mode of (DP) becomes the winning mode corresponding to the small prize, the payout player who pays out the game medium corresponding to the winning small role prize When the player operates the stop operation means (13a, 13b, 13c) after winning the stage (101) and the second normal game start prize, the stop mode of the display means (DP) is changed to the second mode. When the winning mode corresponding to the base game start prize is reached, the game state is shifted from the first base game to the second base game from the next game, and after the player wins the special game start prize, the player performs the stop operation. When the stop mode of the display unit (DP) becomes a winning mode corresponding to the special game start prize by operating the units (13a, 13b, 13c), the game state is changed from the first game to the special game. Game state transfer means (101, S110k, S110k1) to be transferred, and game media paid out in each of the second normal game and the special game In the acquisition quantity counting means (101, S111k, S111v) for generating the acquisition quantity by cumulatively counting the quantity of the game, and each of the second normal game and the special game, if the acquisition quantity exceeds a predetermined quantity, the game Game state return means (101, S111n, S111p, S111x, S111y) for returning the state to the first normal game.

Similarly to the slot machine described above, this slot machine does not detect whether the current game state is the first normal game or the second normal game from the winning rate of the small role prize. Even if the first normal game is advantageous to the player, the special game start prize cannot be transferred to the special game unless the special game start prize is won. The number of times can be controlled by setting the winning probability. Further, in the first normal game, the game state is changed from the next game on condition that the lottery of the second normal game start prize that triggers the transition to the second normal game disadvantageous to the player is executed and won. Since the transition is made to the second normal game, the transition to the special game can be flexibly controlled. In addition, since the second normal game is finished when the acquired quantity exceeds a predetermined quantity and the game state shifts to the first normal game, even if a plurality of slot machines having a large number of fits are installed, the disparity between the stands is reduced. It becomes possible.

In such a slot machine, the lottery means (101, TBL11 to TBL18) receives the second normal game start award and the special game start award during the carry-over period of the second normal game start award and the special game start award. A lottery is executed excluding the lottery object, a period other than the carry-over period of the second normal game start prize in the first normal game, a carry-over period of the second normal game start prize in the first normal game, and the The composite probabilities of a plurality of small role awards are approximately equal in the period of the second normal game, and the winning probabilities of the plurality of small role awards in the special game compared to the first normal game and the second normal game It is preferable to execute the lottery so that the value becomes high. According to the present invention, when the second normal game start prize is won by the lottery means, the special game start prize is not drawn in the carry-over period, so that a highly skilled player does not win the second normal game start prize. Even if the stop operation means is operated, such a player is not advantageously handled. Therefore, game media can be equally given to any player.

In the slot machine described above, the game state includes a specific game, and the start prize includes a specific game start prize that shifts to the specific game when winning, and the lottery means (101, TBL11 to TBL18). Executes the lottery by including the specific game start prize in the lottery targets of the first base game and the second base game, and the game state return means (101, S111n, S111p, S111x, S111y) When winning the specific game start prize in the second normal game, the game state is shifted to the specific game from the next game, and when the specific game is completed, the game state is shifted from the next game to the first normal game. Is preferred. In this case, since the game state is returned to the first normal game when the specific game ends, a variation can be added to the return to the first normal game. In addition, as a specific game, SB game and RB game correspond, for example.

Further, when the lottery means (101, TBL11 to TBL18) wins the specific game start prize in the first normal game, the carry-over period from the game next to the selected game to the game winning the specific game start prize In the above, the lottery result won is carried over and the lottery information is generated together with the lottery result of the current game, and the game state return means (101, S111n, S111p, S111x, S111y) When the specific game start prize is won, it is preferable to shift the game state from the next game to the carry-over period of the specific game start prize in the first normal game. When the specific game ends, the next game shifts to the first normal game. Therefore, in addition to the transition of the first normal game → the carry-over period of the specific game in the first normal game → the specific game → the first normal game, A transition of a game such as a carry-over period of a specific game in a second normal game → a second normal game → a specific game → a first normal game may be considered. However, in either case, there is no substitute for making a transition to the first normal game. If the carry-over period of the specific game in the second normal game is provided, the carry-over period of the specific game in the second normal game must be managed in addition to the carry-over period of the specific game in the first normal game, and the process is complicated become. On the other hand, according to the present invention, since the transition to the carry-over period of the first normal game is made on the condition that the specific game start prize is won in the second normal game, the processing can be simplified.

Further, the lottery means (101, TBL11 to TBL18) generates the lottery information without carrying over to the next game that the specific game start prize was won in the first base game, and the game state return means (101 , S111n, S111p, S111x, S111y) wins the specific game start prize in the second normal game, and if the specific game start prize is not won in the game, the game state is changed from the next game to the first game state. 1 It is characterized by shifting to a normal game. According to the present invention, the game is shifted to the first normal game not only when winning the specific game start prize but also when not winning, so that a low-skilled player and a high-skilled player can be treated equally.

In the slot machine described above, the display unit (DP) includes a plurality of display columns (R1, R2, R3), and the stop operation unit (13a, 13b, 13c) includes the plurality of display columns (R1, R2, R3) is provided corresponding to each of the plurality of display columns (R1, R2, R3), and a plurality of types of symbols including special symbols are arranged in each of the plurality of display columns (R1, R2, R3). , R2, R3), when the stop operation means (13a, 13b, 13c) is operated during the variable display, the display row (R1, R2, ...) at the operation timing of the stop operation means (13a, 13b, 13c) R3) is provided with stop means (101, S109) for advancing and stopping the symbols within a predetermined number of symbols, and the stop means (101, S109) indicates that the lottery information indicates the winning of the specific game start prize. When one stop operation means corresponding to one display row is operated in a state where the plurality of display rows are variably displayed, a winning line (L1 to L1) is operated at the operation timing of the one stop operation means. If the symbol constituting the winning mode of the specific game starting prize is not located within the predetermined number of symbols from L5), the symbols other than the symbols constituting the winning mode of the specific game starting prize are drawn onto the winning line. When the one display column is stopped and the one stop operation unit is operated, and then another stop operation unit corresponding to another display column other than the one display column is operated, It is characterized in that symbols other than symbols constituting the winning mode of the specific game start prize are drawn on the winning lines (L1 to L5) to stop the other display columns. This slot machine shifts the game state from the second normal game to the first normal game on condition that a specific game start prize (for example, the SB prize of the embodiment) is won. Since the internal lottery is executed inside the slot machine, the player is never perceived as having won the specific game start prize. However, when the specific game start prize is won, the stop control of the display row is executed so that the symbols constituting the specific game start prize are drawn into the winning line. Therefore, the player may be informed that the specific game start prize has been won based on the behavior until the display row stops. Therefore, the present invention first, when one stop operation means corresponding to one display row is operated in a state where a plurality of display rows are variably displayed, that is, the stop means, in the first stop operation, If the symbols that make up the specific game start prize could not be drawn into the winning line, draw the symbols other than the symbols that make up the winning mode of the specific game start prize into the winning line when stopping other display columns Stop other display columns. This makes it difficult for the player to detect that the specific game start prize has been won.

More specifically, the stopping means stores a plurality of pieces of stop data for drawing and stopping a predetermined symbol within a predetermined number of symbols on the winning line for each of the plurality of display columns. The plurality of stop data draws the combination of the specific stop data for drawing the symbols constituting the specific game start prize into the winning line within a predetermined number of symbols and the symbols constituting any of the prizes to the winning line. Storage means including no losing stop data, detection means for detecting operation timing for each of the plurality of stop operation means, stoppage of the display information in which the lottery information, the detection result of the detection means, and the variable display has already stopped A determination unit that determines the stop data to be read from the storage unit based on a position; and the stop data determined by the determination unit And a stop control means for stopping the display sequence in which the stop operation has been performed using the read stop data, and the determination means, wherein the lottery information wins the winning of the specific game start prize. In the game shown, when the detection means detects that the one stop operation means is operated, it is decided to read the specific stop data from the storage means, and after the one stop operation means is operated, The detection means detects that the other stop operation means is operated, and symbols other than the symbols constituting the winning mode of the specific game start prize are stopped on the winning line of the one display row. If it is, it is preferable to determine to read the loss stop data from the storage means. In this case, in the process of sequentially stopping the plurality of display columns by operating the plurality of stop operation means, the first stop operation selects the specific stop data that can win the specific game start prize. When there is no possibility of winning the specific game start prize in the stopped display row depending on the stop position, the display line is switched to the loss stop data. This makes it difficult for the player to detect that the specific game start prize has been won.

In the slot machine described above, the plurality of small role awards include a first small role award, and the winning mode of the specific game start award is displayed in at least one display row of the plurality of display rows (R1, R2, R3). The first symbol constituting the winning mode of the first small role award is not arranged within the range of the predetermined symbol number from the symbol constituting the symbol, and the first symbol is arranged outside the predetermined symbol number range. preferable. The present invention presupposes that the maximum number of pull-ins in the display row stop control is a predetermined number of symbols. In this case, if the display row is arranged in the vertical direction, the first symbol does not exist in the range of the predetermined number of symbols in the upward direction on the basis of the symbol of the specific game start prize, and the predetermined symbol in the downward direction The first symbol does not exist in the range of numbers. Therefore, the player cannot operate the stop operation means aiming at both the first small role prize and the specific game start prize. In other words, the operation timing for drawing the symbol of the first small role prize into the winning line and the operation timing for drawing the symbol of the specific game start prize into the winning line can be made exclusive. Here, in a game in which the player is not notified of which prize has been won in the internal lottery, it is a small role prize that can win medals, and if a stop operation is not performed at an appropriate stop timing, a pattern that forms a prize on the winning line It is usual to operate the stop operation means aiming at the first small role prize that cannot be aligned. This makes it difficult for the player to detect that the specific game start prize has been won. Since the first symbol is not arranged within the predetermined number of symbols from the symbols constituting the winning mode of the specific game start prize, the first small role award is a so-called missed award. Even if the stop operation means is operated at such an operation timing, it is different from the 100% winning symbol that can be drawn into the winning line.

In the slot machine described above, the plurality of small role awards include a specific small role award, and the lottery means (101, TBL11 to TBL18) receives the specific game start award in the first normal game and the second normal game. When selected, lottery information indicating that both the specific game start prize and the specific small role prize are won is generated as the lottery result, and the display means (DP) displays a plurality of display columns (R1, R2, R3). The stop operation means (13a, 13b, 13c) is provided corresponding to each of the plurality of display columns (R1, R2, R3), and the plurality of display columns (R1, R2, When the stop operation means (13a, 13b, 13c) corresponding to the variable display in each of R3) is operated, the operation timing of the stop operation means (13a, 13b, 13c) is reached. Stop means (101, S109) for advancing and stopping the symbols of the display row (R1, R2, R3) within a predetermined number of symbols, wherein the stop means (101, S109) includes the lottery information One stop operation corresponding to one display row (R1, R2, R3) in a state where the plurality of display rows are variably displayed in a game showing winning of both the specific game start prize and the specific small role prize When the means (13a, 13b, 13c) is operated, the winning mode of the specific game start prize is configured from the winning line (L1 to L5) at the operation timing of the one stop operation means (13a, 13b, 13c). When the symbol is not located within the range of the predetermined symbol number and the symbol constituting the winning aspect of the specific small role award from the winning line (L1 to L5) is located within the range of the predetermined symbol number, Special The symbols constituting the winning mode of the small role prize are drawn on the winning lines (L1 to L5) to stop the one display row (R1, R2, R3), and the one stop operation means (13a, 13b, After the operation of 13c), the other stop operation means (13a, 13b, 13c) corresponding to the other display columns (R1, R2, R3) other than the one display column (R1, R2, R3) are provided. When operated, only when the symbols constituting the winning mode of the specific game start prize in the one display row (R1, R2, R3) do not stop on the winning line (L1 to L5), When symbols constituting the winning aspect of the specific small role prize from the winning line (L1 to L5) are within the predetermined number of symbols at the operation timing of the other stop operation means (13a, 13b, 13c) The winning design It is preferable to stop on the line (L1-L5).

According to this invention, when the specific game start prize is selected, the lottery means generates lottery information indicating not only the specific game start prize but also the specific small role prize. That is, when a specific game start prize is won by lottery, a specific small role prize is won in duplicate. Further, the plurality of small role awards include a single specific small role award that generates lottery information indicating the winning of only the specific small role award. In other words, when the lottery information indicates the winning of the specified small role award, both when the specified small role award is shown at the same time as the specific game start award and when only the specified small role award is shown. There is. Therefore, even a game that has won a specific small role award does not indicate that a specific game start prize has been won in that game. Then, the stop means draws the symbol of the specific game start prize to the winning line in preference to the symbol of the specific small role award in the first stop operation, but cannot draw the symbol of the specific game start prize to the winning line. If it is possible to draw a specific small role prize into the winning line, the specific small role prize is drawn into the winning line. Then, in the second and subsequent stop operations, when the specific small role award is drawn into the winning line, the symbol of the specific small role award is displayed even if the symbol of the specific game start prize can be drawn into the winning line. Pull into the winning line. The player cannot determine whether he / she has won the specific game start prize or the single specific small role prize. This makes it difficult for the player to detect that the specific game start prize has been won. For example, the lottery unit may select one category from the categories corresponding to one or a plurality of prizes, specify one or more prizes corresponding to the selected category, and generate lottery information. In this sense, “when a specific game start award is selected” means, for example, which category a value (random value) acquired at the timing when the start operation means is operated belongs to such a category. When such a category is specified, lottery information indicating a specific game start prize and a specific small role prize is generated.

More specifically, the stopping means stores a plurality of pieces of stop data for drawing and stopping a predetermined symbol within a predetermined number of symbols on the winning line for each of the plurality of display columns. In the plurality of stop data, the specific stop data for drawing the symbols constituting the specific game start prize to the winning line within a predetermined number of symbols and the specific for drawing the symbols corresponding to the specific small role prize to the winning line Storage means including small role stop data, detection means for detecting the operation timing for each of the plurality of stop operation means, stop of the lottery information, the detection result of the detection means, and the display row in which variable display has already stopped A determination unit that determines the stop data to be read from the storage unit based on a position; and the storage unit that stores the stop data determined by the determination unit. And a stop control means for stopping the display row where the stop operation has been performed using the read stop data, and the determination means includes the lottery information as the specific game start prize and the specific small role prize. When the detection means detects that the one stop operation means has been operated in the game showing the winning, the determination is made to read the specific stop data from the storage means, and the one stop operation means is operated. After that, the detection means detects that the other stop operation means is operated, and the symbols constituting the winning mode of the specific small role award are stopped on the winning line of the one display row. If it is, it is preferable to decide to read out the specific small combination stop data from the storage means. In this case, in the process of sequentially stopping the plurality of display columns by operating the plurality of stop operation means, the first stop operation selects the specific stop data that can win the specific game start prize. When there is no possibility of winning the specific game start prize depending on the stop position in the stopped display row, and there is a possibility of winning the specific small role prize, the display is switched to the specific small role stop data. This makes it difficult for the player to detect that the specific game start prize has been won.

In this slot machine, in at least one display row of the plurality of display rows (R1, R2, R3), the specified small number is within the predetermined number of symbols from the symbols constituting the winning mode of the specific game start prize. It is preferable to arrange the symbols outside the range of the predetermined number of symbols without arranging the symbols constituting the winning mode of the prize. The present invention presupposes that the maximum number of pull-ins in the display row stop control is a predetermined number of symbols. In this case, if the display row is arranged in the vertical direction, there is no symbol that constitutes the winning mode of the specific small role award in the range of the predetermined number of symbols in the upward direction with reference to the symbol of the specific game start prize. In addition, the symbol does not exist in the range of the predetermined number of symbols in the downward direction. Therefore, the player cannot operate the stop operation means aiming at both the specific small role prize and the specific game start prize. In other words, it is possible to make exclusive the operation timing for drawing the symbol of the specific small role prize to the winning line and the operation timing for drawing the symbol of the specific game start prize to the winning line. Here, in a game in which the player is not notified of which prize has been won in the internal lottery, it is a small role prize that can win medals, and if a stop operation is not performed at an appropriate stop timing, a pattern that forms a prize on the winning line It is usual to operate the stop operation means aiming at a specific small role award that cannot be aligned. This makes it difficult for the player to detect that the specific game start prize has been won. In addition, since the symbols constituting the winning mode of the specified small role award are not arranged within the predetermined number of symbols from the symbols configuring the winning mode of the specified game start prize, the specified small role award is a so-called missed award. Yes, the symbol is different from the 100% winning symbol that can be drawn into the winning line regardless of the operation timing of the stop operation means.

The award includes a re-game award that gives a condition for starting a next game without paying out game media as the game value to be given, and the lottery means (101, TBL11 to TBL18) When the specific game start award is selected in the normal game and the second normal game, the lottery information indicating both the specific game start award and the re-game award is generated as the lottery result, and the display means (DP) includes a plurality of display columns (R1, R2, R3), and the stop operation means (13a, 13b, 13c) are provided corresponding to each of the plurality of display columns (R1, R2, R3). When the stop operation means (13a, 13b, 13c) corresponding to the variable display in each of the plurality of display columns (R1, R2, R3) is operated, the stop operation means 13a, 13b, 13c) is provided with stop means (101, S109) for advancing and stopping the symbols of the display sequence within a predetermined number of symbols in the operation timing, and the stop means (101, S109) is the lottery information Is a game in which both the specific game start prize and the replay prize are won, and the plurality of display rows (R1, R2, R3) are variably displayed in one display row (R1, R2, R3). ) Corresponding to one stop operation means (13a, 13b, 13c) is operated from the pay line (L1 to L5) at the operation timing of the one stop operation means (13a, 13b, 13c). When the symbol constituting the winning aspect of the start prize and the symbol constituting the winning aspect of the re-game award are located within the predetermined number of symbols, the symbol constituting the winning aspect of the re-game award The winning lines (L1 to L5) drawn in said one display column on the (R1, R2, R3) is preferably a stop.

According to the present invention, the lottery means generates lottery information indicating not only the specific game start prize but also the re-game prize when the specific game start prize is selected. In other words, when the specific game start prize is won by lottery, the re-game prize is won in duplicate. Further, the plurality of small prizes include a single re-game prize for generating lottery information indicating winning of only the re-game prize. In other words, when the lottery information indicates the winning of the re-game prize, there are both the case where the winning of the specific game start prize is shown simultaneously with the time of the re-game prize and the case where the winning of only the re-game prize is shown. Therefore, even a game that won the re-game prize does not indicate that the specific game start prize has been won in the game. Then, in the first stop operation, the stop means preferentially draws the re-game prize symbol to the winning line over the symbol of the specific game start prize. Therefore, in order to win the specific game start prize, the re-game prize symbol is not within the predetermined number of symbols from the winning line, and the specific game start prize is within the predetermined symbol number from the winning line. In some cases, it is necessary to operate the stop operation means in a timely manner, and a high level of skill is required. This makes it difficult for the player to detect that the specific game start prize has been won. More specifically, the stopping means stores a plurality of stop data for drawing and stopping a predetermined symbol within a predetermined number of symbols on the winning line for each of the plurality of display columns. When the plurality of stop data includes a symbol constituting the specific game start award and a symbol constituting the replay award within a predetermined number of symbols from the winning line, a symbol constituting the replay award is included. Storage means including special stop data for drawing a symbol constituting the specific game start prize into the winning line when the symbol constituting the replay prize is not within a predetermined number of symbols from the winning line. Detection means for detecting the operation timing for each of the plurality of stop operation means, the lottery information, the detection result of the detection means, and the display row in which variable display has already been stopped. Based on a stop position, a determination unit that determines the stop data to be read from the storage unit, and the stop data determined by the determination unit is read from the storage unit, and the stop operation is performed using the read stop data. Stop control means for stopping the display row that has occurred, the determination means in the game in which the lottery information indicates the winning of the specific game start prize and the re-game prize, the detection means is the one stop When it is detected that the operation means has been operated, it is preferable to decide to read the special stop data from the storage means.

Here, when the lottery information in the second base game detects that the specific game start prize is won, a notification means is provided for starting a specific effect after the game or a predetermined number of games have passed. preferable. In this case, since the player can be notified of the transition to the first normal game, the game preference is improved.

In addition, there are a plurality of types of specific games as the specific game, and the specific game start award is composed of a plurality of individual start awards corresponding to each of the plurality of types of specific games, each corresponding to the plurality of individual start awards. The winning modes are different from each other, and the lottery means (101, TBL11 to TBL18) includes, in the first normal game and the second normal game, the plurality of individual start prizes as lottery targets as the specific game start prize. It is preferable to execute a lottery. If the specific game start prize is single, the player will remember the winning mode, and the player can easily detect that the game will shift to the first normal game, but by providing a plurality of specific game start prizes, Transition to the first normal game can be made difficult to understand.

In the slot machine described above, the display unit (DP) includes a plurality of display columns (R1, R2, R3), and the stop operation unit (13a, 13b, 13c) includes the plurality of display columns (R1, R2, R3) is provided corresponding to each of the plurality of display columns (R1, R2, R3), and a plurality of types of symbols including special symbols are arranged in each of the plurality of display columns (R1, R2, R3). , R2, R3), when the stop operation means (13a, 13b, 13c) is operated, the display row (R1, R2, R3) is provided with stop means (101, S109) for advancing and stopping the symbols within a predetermined number of symbols, and the winning mode of the second normal game start prize is stopped at a predetermined position on the winning line (L1-L5) did The special symbols and the next special symbols are arranged within the predetermined number of symbols in each display row (R1, R2, R3), and the game state transition means (101, In S110k, S110k1), when the lottery information indicates the winning of the second base game start prize, the special symbol becomes the prize no matter what timing the stop operating means (13a, 13b, 13c) is operated. It is preferable to control the stop means (101, S109) so that the special symbol stops at a predetermined position on the line (L1 to L5), and to win the second base game start prize.

In this case, even if the player operates the stop operation means so as not to win the second normal game start prize in the state where the second normal game start prize is won by lottery, the second normal game start prize is configured. Stop control is executed so that the symbol is drawn on the winning line and stopped. Accordingly, the game state can be shifted from the next game to the second normal game on condition that the second normal game start prize is won. in this case,
It may be detected that the second base game start prize is won and the game state may be shifted from the next game to the second base game, or the second base game start prize is detected and The game state may be shifted from the game to the second normal game.

The reels R1 to R3 are made of transparent ABS resin or the like, and are affixed to the reel frames 56a to 56c composed of a plurality of spoke portions extending radially from the shaft portion and an annular frame, and the peripheral surfaces of the reel frames 56a to 56c. It is composed of reel bands 58a to 58c on which 21 various symbols (symbol numbers PN: 1 to 21) are printed. The reels R1 to R3 are fixed to the stepping motors 54a to 54c and rotate. For the rotation operation of the reels R1 to R3, stepping motors 54a to 54c that rotate once by supplying pulses of 400 steps are used, and predetermined symbols can be displayed on the reel window 20 by supplying predetermined pulses. . Further, backlight devices 53a to 53c provided with LEDs (not shown) are provided so that light can be irradiated from the inside of the reel bands 58a to 58c. Thus, the player can make the symbols on the reel bands 58a to 58c stand out by irradiating light from the inside of the reel bands 58a to 58c by the backlight devices 53a to 53c.

In addition, the detection plates 57a to 57c are attached to one of the spoke portions, and the reel position detection sensors 55a to 55c can output one pulse of the reel position detection signals 155a to 155c for each rotation of the reels R1 to R3. ing. The detection plates 57a to 57c and the reel band 58a are arranged so that the symbol number PN = 1 is positioned on the winning line L1 in the center of the reel window 20 when 10 steps are advanced after detecting the reel position detection signals 155a to 155c. The position of ~ 58c is set.

In the variable reel display device RL, the reels R1 to R3, the stepping motors 54a to 54c to which the reels R1 to R3 are fixed, the backlight devices 53a to 53c, and the reel position detection sensors 55a to 55c are fixed to the base plates 52a to 52c, respectively. By doing so, it has a single unit configuration. Further, the reel variable display device RL is inserted into the case body 50 by inserting the base plates 52a to 52c along the guide rails 51a to 51c provided on the case body 50 of the reel variable display device RL. Yes.

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, when the reel position detection signals 155a to 155c are detected and 10 steps are advanced, the symbol number PN
= 1 is positioned on the winning line L1 in the center of the reel window 20, and if the process advances 29 steps after detecting the reel position detection signals 155a to 155c, the symbol number PN = 2 is positioned on the winning line L1. If 48 steps are advanced, the symbol number PN = 3 is positioned on the winning line L1, and if 390 steps are advanced, the symbol number PN = 21 is positioned on the winning line L1. When the processing proceeds beyond step 390, reel position detection signals 155a to 155c are detected again. 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.

<4-3: Explanation of Various Games of Slot Machine> FIG. 7 is an explanatory diagram showing the state of a game performed in the slot machine 1. The state of the game is distinguished by the winning probability of each prize in the internal lottery. (1) Start and end of the BB game In FIG. 7A, when the slot machine 1 wins the BB prize in the internal lottery during the execution of the first normal game, When is established and winning, the BB game is started from the next game. The BB game is ended when the acquired number of sheets in the BB game exceeds the specified number. (2) Inside the BB Even if the BB prize is won by the internal lottery during the first normal game, if the BB role is not established in this game, the winning flag of the BB prize is carried over until the next game is won. BB inside. When the BB combination is established within the BB and a prize is won, the BB game is started from the next game. (3) Start and end of the RB game When the RB prize is won in the internal lottery during the first and second normal games, the RB game is played from the next game when the RB role is established in this game or the subsequent game. Be started. A maximum of 12 RB games are played, and when the RB game is won eight times, the RB game is terminated. (4) Inside the RB Even if the RB prize is won by the internal lottery during the first and second regular games, if the RB role is not established in this game, the RB prize winning flag is carried forward until the next game is won. The inside of the RB to be When the RB combination is established in the RB and a prize is won, the RB game is started from the next game. (5) Start and end of the SB game When the SB1 prize is won by the internal lottery during the first and second regular games, the SB1 game is started in the next game when the SB1 role is established only in this game and won. Is done. The SB1 game ends in one game. The same applies to the SB2 award. (6) Start and end of CB game When the CB prize is won by internal lottery during the 1st and 2nd regular games, the CB game starts in the next game when the CB role is established only in this game and won Is done.

When the number of acquired cards in the entire period or a specific period in the second normal game exceeds the specified number, the second normal game is ended and the process returns to the first normal game.

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

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

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

Next, the CPU 101 sequentially increments every 10 nanoseconds in the range of 0000H to 3FFFH, acquires a counter value from the counter circuit that makes one round in about 1.6 milliseconds via the input / output port 107, and sets it as a random value. (S103). Next, referring to the game state data, a prize lottery table corresponding to the state of the game is selected (S104). Using the selected prize lottery table, a determination is made as to which numerical range set for each prize on the prize lottery table the acquired random number value belongs to, and a winning flag for that prize is set (S105). . Next, a stop data table group to be referred to by stop control is selected based on the winning flag set in step S105 (S106).

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

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

In addition, as a method of detecting that the three reels R1 to R3 have reached a constant rotation speed, after a predetermined number of steps have elapsed from the start of rotation, or after a predetermined time has elapsed from the start of rotation (a predetermined number of interruptions have occurred), A method of assuming that a constant rotational speed has been reached by outputting pulses at regular intervals to the stepping motor, or after a predetermined number of steps have elapsed since the start of rotation, or after a predetermined time has elapsed since the start of rotation (a predetermined number of interruptions have occurred) There is a method of determining that a predetermined rotational speed has been reached when a predetermined time has elapsed, a predetermined number of steps have elapsed, a stepping motor has made one revolution, or an index has been detected. That is, in this embodiment, the time point at which the constant rotational speed is detected is set as the reference time point, but the time point at which it is considered that the constant rotational speed is reached may be set as the reference time point.

Then, the CPU 101 performs a reel stop process for stopping the three reels R1 to R3 (S109). As will be described in detail later, in the reel stop process, when stop operation instruction signals 113a to 113c are detected and the stop button is operated, the operation of the stop button is performed based on the stop data table group selected in step S106. The symbol number PN to be stopped is determined from the position and stop data in the stop data table group, the brake force is applied by all-phase excitation that simultaneously excites all winding phases, and 15-step equivalents after starting all-phase excitation Reel stop processing is performed for each reel, which is rotated and stopped by inertia, and when the automatic stop time elapses from the reference time (remaining time runs out), the reels that have not been stopped are automatically Stop.

Next, when all reels are stopped, the CPU 101 determines whether or not a winning combination is established on a valid winning line (S110), and if winning, a game value set for each winning combination is given. To do. Next, a game end determination process is performed (S111), and then a winning flag clear process is performed (S112). Here, if the winning flag established in the game is a start prize that the flag can be carried over, the winning flag is cleared only when winning, and the winning flag is not cleared if it is missed without winning. . On the other hand, if the winning flag established in the game is a start prize or small role prize that the flag cannot carry over, the winning flag is cleared regardless of winning or missing. Subsequently, the prohibition of the bet operation performed in step S102 is canceled (S113), so that the insertion of a game medal or the input of the bet button 11 can be performed, and the process returns to step S100 to prepare for the start of the next game.

<5-2: Prize Lottery Table Determination Process> FIG. 9 is an explanatory diagram showing an example of a lottery according to the state of the game selected in the prize lottery table determination process in step S104. During the first base game, a small role B, small role A, CB, SB2, SB1, RB, BB, MB2, MB1, a replay prize, or lose Set the lottery probabilities for determining at 1000/16384, 300/16384, 70/16384, 60/16384, 60/16384, 50/16384, 160/16384, 30/16384, 30/16384, 2250/16384, respectively. Then, a lottery is performed using the prize lottery table TBL11 in which data indicating the lottery probability is stored, and a winning flag of the winning prize is set.

In the prize lottery table TBL11, the lottery classification data 1000 for the small role B prize is stored in the first memory area of the prize lottery table indicated by the table storage address ADR11, and the obtained random number value belongs to the range of 0 to 999. Indicates that the small role B prize has been won. In the storage area offset by 02H from the top of the prize lottery table, the lottery A prize lottery classification data 300 is stored. If the obtained random number value is in the range of 1000 to 1299, the prize is awarded for the small role A prize. It shows that. CB prize lottery classification data 70 is stored in the storage area offset by 04H from the top of the prize lottery table. If the obtained random number value is in the range of 1300 to 1369, it indicates that the CB prize is won. The storage area offset by 06H from the head of the prize lottery table stores SB2 prize lottery classification data 60. If the obtained random number value is in the range of 1370 to 1429, it indicates that the SB2 prize is won. The storage area offset by 08H from the top of the prize lottery table stores the lottery classification data 60 of the SB1 prize. If the obtained random number value belongs to the range of 1430 to 1489, it indicates that the SB1 prize is won. RB prize lottery classification data 50 is stored in the storage area offset by 0 CH from the head of the prize lottery table. If the obtained random number value is in the range of 1490 to 1539, it indicates that the RB prize is won. BB prize lottery classification data 160 is stored in the storage area offset by 0EH from the top of the prize lottery table. If it belongs to the range of 1540 to 1699, it indicates that the BB prize is won. MB2 prize lottery classification data 30 is stored in the storage area offset by 0 AH from the top of the prize lottery table. If the obtained random number value is in the range of 1700 to 1729, it indicates that the MB2 prize is won. MB1 prize lottery classification data 30 is stored in the storage area offset by 10H from the head of the prize lottery table. If the obtained random number value falls within the range of 1730 to 1759, it indicates that the MB1 prize is won. The re-game prize lottery classification data 2250 is stored in the storage area offset by 12H from the head of the prize lottery table. If the acquired random number value is in the range of 1760 to 4009, it means that the re-game prize is won. Show. It should be noted that the data of the numerical value range belonging to the lose is not stored, and the obtained random number value is sequentially compared with the lottery division data from the small role C prize to the re-game prize, and does not belong to any lottery division data. If it is judged, it is lost. The prize lottery tables TBL12 to 18 described later are the same as the prize lottery table TBL11 except that the prizes to be drawn and the range of numerical values are different.

FIG. 10 is an explanatory diagram showing a prize lottery table selected in each game selected in the prize lottery table determination process in step S104. During the first base game, the prize lottery table TBL11 is selected, and during the second base game, the prize lottery table TBL14 is selected. Therefore, during the first normal game, lottery is performed including the BB prize, MB1 prize and MB2 prize in the start prize, but in the second normal game, these prizes are excluded from the lottery targets. For this reason, as described with reference to FIG. 7, the BB game may be transferred during the first normal game, but the BB game is not transferred during the second normal game. That is, the CPU 101 includes a plurality of second normal game start prizes MB1 and MB2 for transferring the game state to the second normal game in the first normal game, and a plurality of BB prizes for transferring the game state to the BB game (special game). It functions as a transfer lottery means that executes a lottery with the start prize as a lottery object and executes a lottery with a start prize not including the BB prize as a lottery object in the second base game.

In the prize lottery table TBL11 and the prize lottery table TBL14, the winning probabilities of the small role B prize and the small role A prize are set to be the same. Therefore, even if the player has measured the winning rate for the small role A prize and the small role B prize while playing, it is determined whether the current game state is the first normal game or the second normal game. I can't do it.

The prize lottery table TBL12 is selected inside the BB, and the prize lottery table TBL13 is selected inside the RB. During the BB game, the prize lottery table TBL15 is selected, during the RB game, the prize lottery table TBL16 is selected, during the SB1 game and during the SB2 game, the prize lottery table TBL17 is selected, and during the CB game, the prize lottery table TBL18 is selected. To do.

During the BB game and the RB game, the lottery probabilities for determining either the small role B prize, the small role A prize or the loser are set as 15800, 300 and 284, respectively, and the winning flag of the winning prize is set. set. Thus, during the BB game and during the RB game, the lottery probability of the small role B prize is higher than that during the normal game or inside. In this embodiment, in the BB game, only the small role award B has a high probability of drawing, but the small role award A and the small role award B have a high probability, or the small role award A and the small role award B An example is a method of providing a small prize C dedicated to the BB game or the RB game with the same lottery probability as the inside. In any case, during the BB game, the combined probability of the small role award (the sum of the lottery probabilities of a plurality of small role awards) is higher than that during the first and second normal games or inside.

As described above, the BB game has a higher expected value for the number of medals obtained because the winning probability of the small role prize is higher than those of the first and second normal games. And while the 1st normal game is an advantageous game state which can transfer to a BB game, the 2nd normal game is a disadvantageous game state which cannot transfer to a BB game. Thus, by providing an advantageous game state and an unfavorable game state, it is possible to change the progress of a series of games. However, if the second normal game continues for a long time, the fun is lost. Therefore, as described later, when the number of medals acquired in the second normal game reaches a predetermined number, the second normal game is ended and the game state is returned to the first normal game.

When the first normal game advantageous to the player and the second normal game disadvantageous are employed, when the player knows the current game state, the player plays only in the first normal game. As a result, the operating rate of the slot machine 1 is lowered. Therefore, the winning probability of the small role prize is made equal in the first normal game and the second normal game so that the game state cannot be determined from the winning probability of the small role prize. In addition, the winning probability of the small role prize may be in a range that the player cannot discriminate. Specifically, the average number of continuous games of the first normal game is N1, the average number of continuous games of the second normal game is N2, and the larger of N1 or N2 is N. Then, when it is assumed that all of the small prizes won in the internal lottery have been won by playing the N game, each small in the first and second normal games is within a range that is not determined to be significant by a statistical test. What is necessary is just to set the winning probability of the winning prize.

By the way, the transition to the second base game is performed by winning the MB1 prize or the MB2 prize, which is the start prize of the second base game (see step S110m1 in FIG. 19 described later). Therefore, when it is determined that the MB1 prize or the MB2 prize has been won, the player is perceived to shift from the next game to the second normal game. For this reason, in this embodiment, the winning mode of the MB1 prize is composed of a set of different types of symbols such as “Watermelon-Plum-Bell”, and the winning mode of the MB2 prize is “Bell-Plum-Watermelon”. It is devised not to catch the eyes of the person.

In addition, although winning a prize is on condition that the symbols constituting the prize stop on the activated winning lines L1 to L5, an irregular winning line may be adopted for the MB1 prize and the MB2 prize. . Specifically, the winning line may be a broken line as shown in FIG. In this case, the winning line L6 is composed of symbol stop positions M1, U2, and U3, the winning line L7 is composed of symbol stop positions M1, D2, and D3, and the winning line L8 is composed of symbol stop positions U1, M2, and U3. The winning line L9 includes symbol stop positions D1, M2, and D3, and the winning line L10 includes symbol stop positions D1, U2, and D3. From the viewpoint of making it difficult to understand the winning, the winning mode in the start prize of the second normal game may be, for example, on condition that predetermined symbols are aligned on the winning lines L6 to L10.

<5-3: Winning Flag Setting Process> FIG. 11 is a flowchart showing the contents of the winning flag setting process in step S105. In this winning flag setting process, a winning flag effective for the game is set from the award lottery tables TBL11 to TBL18 corresponding to the acquired random number value and the game state determined in step S104. However, if the prize lottery table is different depending on the game, the winning flag to be set is also different, and the winning flag to be set is different if the random number is different even in the same prize lottery table. If there is a winning flag carried over from the previous game, a plurality of winning flags are set by combining the carry-over flag and the random number value acquired in the game.

First, the CPU 101 determines whether the small role B prize has been won or whether the CB game is in progress, whether the acquired random number value belongs to the range indicated by the lottery division data of the small role B prize in the prize lottery table, or the game state It is determined by checking whether bit 5 of the data is set to “1” (S105a). If it is determined that the data belongs, the small role B prize winning flag of bit 2 of the winning information 2 data is set to “1”. "(S105a1).

Next, the CPU 101 determines whether or not the small role A prize is won based on whether or not the acquired random number value belongs to the range indicated by the lottery classification data of the small role A prize in the prize lottery table (S105b). If it is determined that, the small role A prize winning flag of bit 1 of the winning information 2 data is set to “1” (S105b1).

Next, the CPU 101 determines whether or not it is during the first normal game, during the second normal game, during the SB game, or during the CB game by checking the game state data (S105c), and during the first normal game, When it is determined that the second normal game, the SB game, and the CB game are not being performed, the process proceeds to step S105j. If it is determined in step S105d that the game is in the first normal game, the second normal game, the SB game, or the CB game, the acquired random number value indicates whether or not the CB prize is won. It is determined whether the lottery table belongs to the range indicated by the lottery classification data of the CB award (S10d). If it is determined that it belongs, the CB award winning flag of bit 6 of the winning information 1 data is set to “1”. (S105d1).

Next, the CPU 101 determines whether or not the SB2 award has been won based on whether or not the acquired random number value belongs to the range indicated by the lottery classification data of the SB2 award in the award lottery table (S105e). In such a case, the SB2 prize winning flag of bit 5 of the winning information 1 data is set to “1” (S105e1).

Next, the CPU 101 determines whether or not the SB1 prize has been won based on whether or not the acquired random number value belongs to the range indicated by the lottery classification data of the SB1 prize in the prize lottery table (S105f). In such a case, the SB1 award winning flag in bit 4 of the winning information 1 data is set to “1” (S105f1).

Next, the CPU 101 determines whether or not the RB award has been won by determining whether or not the acquired random number value belongs to the range indicated by the RB award lottery classification data in the award lottery table (S105g). In such a case, the RB award winning flag of bit 3 of the winning information 1 data is set to “1” (S105g1).

Next, the CPU 101 determines whether or not it is during the first normal game, during the SB game or during the CB game by checking the game state data (S105h), and during the first normal game, during the SB game and during the CB game. If it is determined that it is not, the process proceeds to step S105m. If it is determined in step S105h that the game is in the first normal game, the SB game, or the CB game, whether or not the BB prize is won is determined based on whether the acquired random number is the BB prize lottery in the prize lottery table. It is determined by whether or not it belongs to the range indicated by the division data (S105j). If it is determined that it belongs, the BB prize winning flag of bit 2 of the winning information 1 data is set to “1” (S105j1).

Next, the CPU 101 determines whether or not the MB2 prize has been won based on whether or not the acquired random number value belongs to the range indicated by the lottery classification data of the MB2 prize in the prize lottery table (S105k). In such a case, the MB2 prize winning flag of bit 1 of the winning information 1 data is set to “1” (S105k1).

Next, the CPU 101 determines whether or not the MB1 prize has been won based on whether or not the acquired random number value belongs to the range indicated by the MB1 prize lottery classification data in the prize lottery table (S105n). In such a case, the MB1 prize winning flag of bit 0 of the winning information 1 data is set to “1” (S105n1).

Next, the CPU 101 determines whether or not the BB game or the RB game is in progress by checking whether any of the bits 2 to 3 of the game state data is set to “1” (S105p). If it is determined that a game or an RB game is in progress, the process proceeds to step S105r. If it is determined in step S105p that the game is not in the BB game or the RB game, whether or not the re-game prize has been won is determined whether the acquired random number value belongs to the range indicated by the re-game prize lottery classification data in the prize lottery table (S105q), if it is determined that it belongs, the re-game prize winning flag of bit 0 of the winning information 2 data is set to “1” (S105q1).

Next, the CPU 101 determines whether or not the second normal game is being played by checking whether any of the bits 0 to 1 of the game state data is set to “1” (S105r). If it is determined that the game is not a regular game, the process is terminated. When it is determined in step S105r that the game is the second normal game, whether the SB prize or RB prize is won is indicated by the lottery division data of the SB prize or RB prize in the prize lottery table. It is determined whether it belongs to the range (S105s), and if it is determined that it belongs, the bits 0 to 1 of the game state data are cleared and the second normal game is being played (2A normal game or 2B normal game) (In game) is cleared (S105s1), and the process is terminated. That is, when the SB prize or the RB prize is won, the second normal game ends.

In addition, in the flowchart shown in FIG. 11, when there is a carry-over flag from the previous game, it is specified that a plurality of winning flags are set at the same time when a new prize is won in this game. However, when a new prize is won, if the prize is won, the bit corresponding only to the prize is set to “1” without affecting other bits, so that a plurality of bits are set to “1” at the same time. May be. In this example, the winning information 1 data is divided as the storage device for storing the winning flag corresponding to the start prize, and the winning information 2 data is stored as the storing device for storing the winning flag corresponding to the replay prize and the small role award. You may make it memorize | store with the memory | storage device. The plurality of bits being “1” means that the plurality of bits are “1” considering the winning information 1 data and the winning information 2 data together. In addition, as winning information, a flag is managed as information indicating 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. The winning information 1 data functions as transfer lottery information indicating winning / losing of the start prize, and the CPU 101 functions as a transfer lottery means for generating the transfer lottery information. Further, the winning information 2 data functions as a small role prize lottery information indicating the winning / losing of the small role prize, and the CPU 101 functions as a small role prize lottery means for generating the small role prize lottery information.

<5-4: Stop Data Selection Process> FIG. 13 is a flowchart showing the content of the stop data selection process in step S106. In this stop data selection process, a stop data table group to be used in stop control is selected from the winning flag set in step S105. As shown in FIG. 14, the stop data table groups TBL21 to TBL29 set for each award further include three stop data table groups TBL21A to TBL21C for the left reel R1, the middle reel R2, and the right reel R3 (replay game). In addition, for each reel, the stop data tables TBL21A1 to TBL21A5 (replay L1 of the replay L1) are distributed for each winning line so that the stop positions of the symbols are distributed to the upper line (L1), the lower line (L3), and the like. Example). In addition, since the stop data table is switched according to the stop operation of the player, it is not necessary to specify and select the stop data table to be finally used that is selected during the stop operation.

First, the CPU 101 refers to bit 0 of the winning information 2 data to determine whether or not the re-game prize winning flag is set (S106a). If it is determined that it is set, the re-game award stop data is determined. The table group TBL21 is selected (S106a1).

Next, the CPU 101 refers to bit 2 of the winning information 2 data to determine whether or not the small role B prize winning flag is set (S106b). If it is determined that the small role B prize winning flag is set, the small role B prize is determined. The stop data table group for use TBL22 is selected (S106b1).

Next, the CPU 101 refers to bit 1 of the winning information 2 data to determine whether or not the small role A prize winning flag is set (S106c). The stop data table group TBL23 for use is selected (S106c1), and this process is terminated.

Next, the CPU 101 determines whether or not the CB award winning flag is set with reference to bit 6 of the winning information 1 data (S106d), and if it is determined that it is set, the CB award stop data table. The group TBL24 is selected (S106d1), and this process ends.

Next, the CPU 101 refers to bit 5 of the winning information 1 data to determine whether or not the SB2 prize winning flag is set (S106e), and if it is determined that it is set, the SB2 prize stop data table. The group TBL25-2 is selected (S106e1), and this process is terminated.

Next, the CPU 101 determines whether or not the SB1 prize winning flag is set with reference to bit 4 of the winning information 1 data (S106f), and if it is determined that it is set, the SB1 prize stop data table. The group TBL25-1 is selected (S106f1), and this process is terminated. When the SB1 award or the SB2 award is won in the second base game, a losing stop data table group TBL29 described later may be selected. Since the winning flag is not carried over to the SB1 prize and the SB2 prize, the SB1 prize and the SB2 prize are not won in the second normal game. Also, the player cannot know the result of the internal lottery. In this case, the game state may be shifted to the first normal game on condition that the SB1 prize and the SB2 prize are won. In the game where the SB1 prize or SB2 prize is won, when the symbols constituting the winning mode corresponding to the SB1 prize or SB2 prize are positioned within 4 frames from the winning line at the timing of the reel stop operation to be stopped first, If the symbol that makes up the winning mode corresponding to the SB1 prize or SB2 prize is not located within 4 frames from the winning line at the timing of the stop operation, the symbol that does not constitute the winning mode is controlled. Control to stop on the winning line. Further, if the symbols constituting the winning mode corresponding to the SB1 prize or the SB2 prize cannot be stopped on the winning line as a result of the first reel stopping operation, SB1 Even when the symbols constituting the winning mode corresponding to the award or the SB2 award can be stopped on the winning line, the symbols are not stopped on the winning line. In this case, in the stop control of the remaining reels, a stop data table corresponding to the loss may be selected instead of the stop data table corresponding to the SB1 prize or SB2 prize. By performing such stop control, it is possible to make the player think that the game is a lose game, and to make it difficult to detect that the SB1 prize or the SB2 prize is a winning game. Furthermore, a symbol constituting a winning mode corresponding to the SB1 award or SB2 award and a symbol constituting a winning mode corresponding to a small role award (first small role award) such as a missing small role B award (for example, cherry) It is preferable to arrange so that the distance from the pattern is more than 4 frames. Players tend to perform a stop operation aiming at a missed small role award, and if arranged in this way, if not notified that the SB award has been won, the player switches from the small role B award to the SB award and stops. As a result, even if the SB1 prize or SB2 prize is won, the player can reduce the chance of winning the SB prize because the player performs a stop operation aiming at the small role B prize.

Next, the CPU 101 refers to bit 3 of the winning information 1 data to determine whether or not the RB prize winning flag is set (S106g). The group TBL26 is selected (S106g1), and this process ends.

Next, the CPU 101 refers to bit 2 of the winning information 1 data to determine whether or not the BB prize winning flag is set (S106h). If it is determined that the BB prize winning flag is set, the BB prize stop data table is determined. The group TBL27 is selected (S106h1), and this process ends.

Next, the CPU 101 refers to bit 1 of the winning information 1 data to determine whether the MB2 prize winning flag is set (S106j). If it is determined that the MB2 prize winning flag is set, the MB2 prize stop data table is determined. The group TBL28-2 is selected (S106j1), and this process ends.

Next, the CPU 101 refers to bit 0 of the winning information 1 data to determine whether or not the MB1 award winning flag is set (S106k). The group TBL28-1 is selected (S106k1), and this process is terminated.

Finally, if the CPU 101 determines that any winning flag is not set, the CPU 101 selects the lost data table group TBL29 for losing (S106n) and ends the process.

FIG. 15 is an explanatory diagram showing a stop data table to be stopped at the pay line L1 used in the left reel selected in the stop data selection process. FIG. 15A shows the symbol arrangement of the left reel band, and FIGS. 15B, 15C and 15D show the small role A award stop data table TBL23A1, the replay award stop data tables TBL21A1 and BB, respectively. The award stop data table TBL27A1 is shown. These stop data tables indicate from “0” to “4” that instructs to stop from a symbol position (stop symbol position) nearest to the stop position where the stop operation instruction signal 113c is detected to a number of symbols ahead. The number of advance frames is stored. “0” means stop at the stop symbol position, and “4” means stop at the stop symbol position four frames ahead. Since the stop data table only needs to be able to instruct where the symbol is advanced and stopped, the symbol number PN to be stopped may be stored instead of the number of advance frames such as “0” to “4”. Good.

The small symbol A stop data table TBL23A1 can stop the bell symbol in the middle stage (winning line L1 position) regardless of the symbol number (stop symbol number) of the stop symbol position. Also, in the re-game award stop data table TBL21A1, the plum symbol can be stopped at the middle stage (winning line L1 position) regardless of the stop symbol number. Thus, if five of the 21 symbols are arranged within an interval of 4 frames, the symbol can always be stopped at the middle stage (position of the winning line L1) regardless of the symbol number. Such bell designs and plum designs are called 100% retracted designs.

On the other hand, in the BB award stop data table TBL27A1, the red 7 symbols can be stopped in the middle stage (winning line L1 position) only at the five stop symbol numbers “7” to “11”. When the stop symbol numbers are “1” to “3”, “16” to “20”, or “21”, the white 7 symbols are stopped in the middle. The reason why the white 7 symbol is stopped is to notify the player that the red 7 symbol cannot be stopped by displaying it as a reach eye. Even if the winning combination is not established in this game, such as the BB Award or the RB Award, the winning flag of the next game is set, and in the stop data table of the symbol which is not 100% drawn symbol, a specific stop symbol The number of frames is set so as to stop the symbol for the number, and the number of frames advanced is set so as to reach the reach for the other stopped symbol numbers. By displaying the reach, the player can know that the winning flag is set.

For example, when the player's stop operation timing is the case where the symbol number (stop symbol number) is “7”, when the small role A prize stop data table TBL23A1 is selected, the advance frame number “2” is set. Acquire, advance 2 frames from the stop symbol number, display the bell symbol of symbol number “9” in the middle, and if the replay award stop data table TBL21A1 is selected, acquire the advance frame number “3” Then, three frames are advanced from the stop symbol number, and the plum symbol of symbol number “10” is displayed in the middle. When the BB award stop data table TBL27A1 is selected, the advance frame number “4” is acquired and the red symbol of symbol number “11” is displayed in the middle row by proceeding four frames from the stop symbol number. Depending on the stop data table selected in this way, even if the same stop symbol number is used, the symbols to be stopped in the middle stage are different.

<5-5: Reel Stop Processing> FIGS. 16 to 17 are flowcharts showing the contents of the reel stop processing in step S109. This reel stop process is an operation stop control process for stopping the reels according to the stop data in the stop data table group, and is stopped after the automatic stop time elapses from the reference time until the last stop reel is automatically stopped. If the stop operation is performed between the automatic stop process for controlling the reel so as to automatically stop if no operation is performed and the automatic stop time from the reference time to the last stop of the reel. It includes a stop control management process for managing stop control so that the reel is stopped by the operation stop control process. The details will be described below.

First, the CPU 101 determines whether or not the automatic stop time has elapsed from the reference time (whether or not the timer value indicating the remaining time has become 0) (S109a) and whether or not the first stop button stop operation has been performed. Is determined based on the stop operation instruction signals 113a to 113c (S109b).

In step S109b, when any one of the stop operation instruction signals 113a to 113c is detected, it is determined that the first stop button stop operation has been performed. In this case, a stop button number indicating the type of the stop button is acquired from the detected stop operation instruction signals 113a to 113c, and a symbol number (stop symbol number) immediately after the stop operation is acquired (S109c). Specifically, the stop button number and the stop symbol number at the timing are acquired by detecting stop operation instruction signals 113a to 113c that are output when the stop buttons 13a to 13c are pressed. In this example, stop button numbers “1”, “2”, and “3” are assigned to the stop buttons 13a, 13b, and 13c, respectively.

On the other hand, when it is determined in step S109a that the automatic stop time has elapsed, the stop button number “3” and the stop 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 stop data table groups that can be used from the stop button number among the stop data table groups based on the winning flag selected in the reel stop data table group selection process in step S106 (S109d). Specifically, it is determined whether the symbol to be stopped can be stopped at any one of an upper stage, a middle stage, and a lower stage. In the case of the left reel R1, a winning line L2 or L4 is a winning line candidate if it can be stopped in the upper stage, a winning line L1 if it can be stopped in the middle stage, or a winning line L3 or L5 if it can be stopped in the lower stage. In the case of the middle reel R2, the winning line L2 is a candidate for the winning line if it can be stopped in the upper stage, the winning line L1, L4 or L5 if it can be stopped in the middle stage, and the winning line L3 if it can be stopped in the lower stage. In the case of the right reel R3, a winning line L2 or L5 is a winning line candidate if it can be stopped in the upper stage, a winning line L1 if it can be stopped in the middle stage, or a winning line L3 or L4 if it can be stopped in the lower stage. If it is possible to stop at a plurality of stages, one stop data table for a predetermined line is selected by lottery or the like from among the winning line candidates combined with them.

Next, the CPU 101 determines a stop data table based on the stop button number (S109f). Next, the CPU 101 acquires the number of advance frames corresponding to the acquired stop symbol number (S109g), and stops the reel that has been stopped based on the advance number of frames (S109h).

Next, the CPU 101 determines whether or not the automatic stop time has elapsed from the reference time (the timer value indicating the remaining time has become 0) and (S109j) whether or not the second stop button stop operation has been performed. The determination is made based on the stop operation instruction signals 113a to 113c (S109k).

In step S109k, when any one of the stop operation instruction signals 113a to 113c other than those already detected is detected, it is determined that the second stop button stop operation has been performed. In this case, a stop button number indicating the type of the stop button is acquired from the detected stop operation instruction signals 113a to 113c, and a symbol number (stop symbol number) immediately after the stop operation is acquired (S109m).

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

Next, the CPU 101 determines a stop data table adapted to the stop position of the already stopped reel based on the stop button number (S109p). Next, the CPU 101 acquires the advance frame number corresponding to the acquired stop symbol number (S109q), and stops the reel that has been stopped based on the advance frame number (S109r).

Next, the CPU 101 stops whether or not the automatic stop time has elapsed from the reference time (the remaining time indicated by the timer value has disappeared) (S109s) and whether or not the third stop button stop operation has been performed. The determination is made based on the operation instruction signals 113a to 113c (S109t).

In step S109t, when any one of the stop operation instruction signals 113a to 113c other than those already detected is detected, it is determined that the stop operation of the third stop button has been performed. In this case, a stop button number indicating the type of the stop button is acquired from the detected stop operation instruction signals 113a to 113c, and a symbol number (stop symbol number) immediately after the stop operation is acquired (S109u).

On the other hand, if the automatic stop time has elapsed in step S109s, the stop button number and stop symbol number of the remaining reels rotating at that time are acquired (S109u1). Next, it is determined whether or not the result of the internal lottery is a loss or a prize that allows 100% winning (S109z). If it is determined that the internal lottery is lost or the prize is 100%, the process proceeds to step S109v. Although details will be described later, the processing after step S109t is processing for normal reel stop control (operation stop control processing) for stopping an unstopped reel using the determined stop data table. That is, when the CPU 101 determines that the internal lottery has been lost or the winning has been confirmed, the CPU 101 performs normal reel stop control. The reason for this will be described below.

[If lost in internal lottery] If lost in the internal lottery, there will be no winning even if normal reel stop control is performed. In addition, the automatic stop control process avoids winning by predetermining the stop position of the unstopped reel according to the state of the stopped reel, so that the normal reel stop using the stop data table is used. As in control, the amount of data to be used increases as the variation of the stop position increases. As described above, normal reel stop control is performed when the internal lottery is lost.

[In the case of a prize capable of winning 100%] Examples of prizes that can be confirmed when at least one reel is not stopped include a replay prize, a small part A prize, a small part B prize, an MB1 prize, And there are MB2 awards. As shown in FIG. 6 and FIG. 15, since each of the re-game prize and the small role A prize is composed only of 100% pull-in symbols, the re-game prize or small role A prize is won by internal lottery. For example, the normal reel stop control based on the player's stop operation wins a prize regardless of the stop operation timing. It is harsh to the player to prohibit such winnings because only the remaining reels are automatically stopped. Also, as shown in FIG. 6, since the combination related to the small role B prize is a combination of symbols of “Cherry-ANY-ANY”, the small role B prize is won by an internal lottery and based on the player's stop operation If the left reel is stopped so that the cherry symbol is positioned on the winning line by the normal reel stop control, the winning is determined regardless of the timing of the stop operation of the middle reel and the right reel. In this case, no matter how the stop positions of the middle reel and the right reel are controlled, it cannot be lost, so there is no point in switching to control control. As described above, the normal reel stop control is performed when the winning is definite. That is, when the predetermined condition is satisfied by executing step S109z, the CPU 101 does not perform the automatic stop process for stopping the unstopped reel so as not to win if the stop operation is not performed until the end. By executing the stop control process for operation with the time when the automatic stop time has elapsed as the detection time of the stop signal, the symbols that make up the prizes that are within the predetermined range from the activated pay line are displayed on the activated pay line It functions as a stop control means for operation that is pulled in and stopped.

Next, the CPU 101 determines a stop data table adapted to the stop position of the already stopped reel based on the stop button number (S109t). Next, the CPU 101 acquires the advance frame number corresponding to the acquired stop symbol number (S109u), stops the reel that has been stopped based on the advance frame number (S109v), and ends this process.

On the other hand, if it is determined in step S109w 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 ( S109x), the automatic stop process is started (S109y).

<5-6: Winning Determination Process> FIG. 18 is a flowchart showing the contents of the winning determination process in step S110. In this winning determination process, the combination of symbols arranged on the winning line after the reels are stopped is checked to determine whether or not a winning is achieved. If it is determined that a prize has been won, a process for starting another type of game is performed if the prize is a start prize, and a payout is awarded if the prize is a small prize.

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

Next, the CPU 101 determines whether or not a re-game prize has been won (S110c). If it is determined that a win has been won, the re-game prize winning flag of bit 0 of the winning information 2 data is cleared (S110c1). Subsequently, an automatic bet process is performed (S100a in FIG. 8), and the process returns to step S101.

Next, the CPU 101 determines whether or not a small role B prize has been won (S110e). If it is determined that a prize has been won, a payout process for two medals is performed (S110e1). Subsequently, it is determined whether or not a small role A prize has been won (S110f). If it is determined that a prize has been won, a payout process for 15 medals is performed (S110f1). In these payout giving processes, a payout credit process is performed in which the number of payouts is added to the credit up to the credit upper limit value (50 cards), and a payout for paying out medals from the medal payout device to the medal tray 40 for the portion exceeding the credit upper limit value. Switch to processing.

Next, the CPU 101 determines whether or not a CB award has been won (S110g). If it is determined that a CB award has been won, the CB game flag in bit 5 of the game state data is set to "1" (S110j1). .

Next, the CPU 101 determines whether or not the SB1 award to the SB2 award has been won (S110h). If it is determined that the SB1 has been won, the CPU 101 sets the SB game flag in bit 4 of the game state data to “1”. (S110h1).

Next, the CPU 101 determines whether or not an RB prize has been won (S110j). If it is determined that a prize has been won, the RB game flag in bit 3 of the game state data is set to "1" (S110j1). . Subsequently, the maximum small part winning number (remaining winning number) in the RB game is set to 8, and the maximum game number (remaining maximum game number) is set to 12 (S110j2).

Next, the CPU 101 determines whether or not the BB prize has been won (S110k). If it is determined that the BB prize has been won, the BB game flag in bit 2 of the game state data is set to “1” (S110k1). The acquired number counter is cleared (S110k2).

Next, the CPU 101 further sets the RB game flag of bit 3 of the game state data to “1” (S110k3). Subsequently, the maximum number of small part winnings (remaining winnings) in the RB game is set to 8 and the maximum number of games (remaining maximum number of games) is set to 12 (S110k4). By the processing in steps S110k3 and S110k4, the RB game can be started from the first game of the BB game. If steps S110k3 to S110k4 are omitted, B
The RB game is not executed immediately after the start of B, and the RB game can be started when winning the RB award.

Next, the CPU 101 determines whether or not the MB1 award or the MB2 award has been won (S110m), and if it is determined that the winning has been won, the normal 2A in-game flag of bit 0 or bit 1 of the game state data or the normal 2B The in-game flag is set to “1” (S110m1), and the acquired number counter value is cleared (S110m2). Thereafter, this process is terminated.

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

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

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

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

Next, the CPU 101 determines whether or not the BB game is being played with reference to bit 2 of the game state data (S111h). If it is determined that the BB game is not being executed, the CPU 101 proceeds to step S111q.

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

Next, the CPU 101 compares the acquired number counter value with the acquired number upper limit determination value determined in each BB game (S111n). The acquired number upper limit determination value is a value that is 15 smaller than the acquired number upper limit value that must not be exceeded during the game and determined for each BB game. If the acquired number upper limit determination value is exceeded in step S111n, the BB game flag (bit 2) in the game state data is cleared (S111p).

Next, the CPU 101 refers to bit 2 of the game state data to determine whether or not the BB game is being played and not being the RB game (S111q), and whether or not the BB game is being played or the BB game is being played and the RB game is being played. If it is determined that, the process proceeds to step S111t.

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

Next, the CPU 101 refers to bits 0 to 1 of the game state data to determine whether or not the second normal game is being played (S111t). If it is determined that the second normal game is not being played, the CPU 101 proceeds to step S111z. To do.

On the other hand, if it is determined in step S111t that the second normal game is in progress, it is determined whether or not a small role prize is won and a dividend is awarded in this game (S111u). When the small prize is awarded and a payout is awarded, the payout is added to the acquired number counter value (S111v), and the acquired number is displayed on the acquired number display 23b (S111w).

Next, the CPU 101 compares the acquired number counter value with the acquired number upper limit determination value determined in the second normal game (S111x). The acquired number upper limit determination value is a value that is 15 smaller than the acquired number upper limit value that must not be exceeded during the game determined in the second normal game. When the acquired number upper limit determination value is exceeded in step S111x, the second normal game (during 2A normal game or 2B normal game) flag (bits 0 to 1) of the game state data is cleared (S111p).

Next, the CPU 101 refers to bits 4 to 5 of the game state data to determine whether or not the SB game or the CB game is in progress (S111z). .

On the other hand, if it is determined in step S111z that any of the SB game or CB game is in progress, the game state data flag (bits 4 to 5) is set in order to end these games in one game. It is cleared (S111z1), and this process ends.

In this example, the upper limit determination value for the number of acquisitions, which is an end condition, is matched between the 2A normal game corresponding to the MB1 award and the 2B normal game corresponding to the MB2 award, but the MB1 award and the MB2 award are the same. The acquisition quantity upper limit value may be different. The second normal game is a disadvantageous game for the player. However, by providing a difference in the upper limit of the number to be acquired, the variation of the game can be increased and the preference can be improved.

<5-8: Winning Flag Clearing Process> FIG. 22 is a flowchart showing the contents of the winning flag clearing process in step S112. In this winning flag clearing process, the winning flag set by internal lottery or the like during one game is cleared at the end of one game based on the type of winning flag and the result of the game, or carried over to the next game without being cleared. Do things.

First, the CPU 101 determines that a flag relating to a start prize without carryover (SB prize winning flag and RB prize winning flag), replay prize winning flag, small role A prize winning flag and small role B prize winning flag is one game regardless of winning. Therefore, bits 4 to 6 of the winning information 1 data and bits 0 to 2 of the winning information 2 data are cleared (S112a).

Next, the CPU 101 refers to bit 3 of the winning information 1 data to determine whether or not the RB award winning flag is set (S112b). If it is determined that the flag is set, the RB award is further determined. Whether or not a prize has been won is determined (S112c). If it is determined that the RB combination has been established and the prize has been won, the RB prize winning flag is cleared (S112d). If it is determined in step S112c that no winning has been made, the RB internal game in-progress flag of bit 7 of the game state data is set to “1” (S112e), and the RB internal is determined from the next game.

Next, the CPU 101 refers to bit 2 of the winning information 1 data to determine whether or not the BB prize winning flag is set (S112f). If it is determined that the flag is set, the CPU 101 further determines the BB prize winning flag. Is determined (S112g). If it is determined that the BB combination has been established and the prize has been won, the BB prize winning flag is cleared (S112h), and the process ends. If it is determined in step S112g that no winning has been made, the BB internal game in-progress flag of bit 6 of the game state data is set to “1” (S112j), and the BB internal is determined from the next game.

Next, the CPU 101 refers to bit 1 of the winning information 1 data to determine whether or not the MB2 prize winning flag is set (S112k). If it is determined that the flag is set, the MB2 prize winning is determined. The flag is cleared (S112m), and this process ends.

Next, the CPU 101 refers to bit 0 of the winning information 1 data to determine whether or not the MB1 prize winning flag is set (S112n), and if it is determined that the flag is set, the MB1 prize winning is determined. The flag is cleared (S112p), and this process ends.

In this embodiment, the symbols constituting “Watermelon-Plum-Bell” or “Bell-Plum-Watermelon”, which is a combination of symbols related to MB1 Award and MB2 Award, are not affected by the stop timing of the player on any reel. It consists of 100% pull-in symbols that can be aligned on the winning line. In other words, a game in which these awards are won always wins. Therefore, in the determination process in step S112k or S112n, determination of the presence / absence of a winning is omitted. Specifically, in the reel stop control employed in the present embodiment, when the reel stop buttons 13a to 13c are operated during the rotation of the reels R1 to R3, the CPU 101 applies the symbols of the reels R1 to R3 to a predetermined symbol from the operation timing. Advancing within a range of numbers (4 frames in this example) and stopping. On the other hand, the symbols (special symbols) “Bell”, “Plum”, and “Watermelon” that constitute the MB1 award and MB2 award are within a predetermined number of symbols within a predetermined number of symbols in the reels R1 to R3. Is arranged. Then, when the MB1 prize or the MB2 prize is won, the CPU 101 performs control so that the special symbol stops on the winning line regardless of the timing at which the reel stop buttons 13a to 13c are operated. In other words, in the present embodiment, winning the MB1 prize or MB2 prize is a necessary and sufficient condition for winning the MB1 prize or MB2 prize, and the CPU 101 is required to win the MB1 prize or MB2 prize. In addition, the game state is shifted from the first normal game to the second normal game. In this case, as described with reference to FIG. 19, the CPU 101 may detect that the MB1 prize or the MB2 prize has been won and set the second normal game in-progress flag (S110m), or the internal It may be detected that the MB1 prize or the MB2 prize is won by lottery, and the second normal game flag may be set.

<Modifications> While the present invention has been described above in relation to the most practical and preferred embodiments at the present time, the present invention is not limited to the embodiments disclosed herein. The present invention is not limited, and can be appropriately changed without departing from the spirit or idea of the invention that can be read from the claims and the entire specification, and a slot machine with such a change is also included in the technical scope of the present invention. Must be understood as being. For example, the following modifications are naturally included in the present invention.

(1) In the above-described embodiment, the symbols constituting the MB1 award and the MB2 award are configured with 100% pull-in symbols, but the present invention is not limited to this. In this case, even if the MB1 prize or the MB2 prize is won in the internal lottery, the MB1 prize or the MB2 prize is not necessarily won in the game, and a carryover of the winning flag may occur. If it is not a 100% pull-in symbol, after the player has won the MB1 prize or the MB2 prize, the player operates the reel stop buttons 13a to 13c so that the stop mode of the reels R1 to R3 corresponds to the MB1 prize or the MB2 prize. In the winning mode, it is preferable to shift the game state from the first normal game to the second normal game.

Further, it is preferable that the CPU 101 does not execute the lottery of the start prizes such as the MB1 prize and the MB2 prize during the period in which the winning flags of the MB1 prize and the MB2 prize are carried over, like the BB prize and the RB prize. Specifically, the lottery may be executed using the prize lottery table TBL13 in the BB shown in FIG. 10 during the period when the winning flags of the MB1 prize and the MB2 prize are carried over. In this case, until the MB1 prize or MB2 prize in the first base game is won for the first period, the MB1 prize or MB2 prize in the first base game is won and the MB1 prize or MB2 prize is won. Assuming that the second regular game is the second period, the CPU 101 has almost the same winning probability of the small role award in the first period and the second period, and the small game award in the BB game compared to the first period and the second period. It is preferable to execute the lottery so that the winning probability is high.

(2) In the embodiment and the modification described above, as described with reference to FIG. 7A, when the SB1 prize, the SB2 prize, or the RB prize is won in the second normal game, the game state is changed to the SB game or When the SB game or the RB game is finished, the game state is returned to the second normal game when the SB game or the RB game is finished. However, the present invention is not limited to this, and when the SB game or the RB game is finished, the game state is changed. Although the game is returned to the second normal game, the game state may be returned to the first normal game when the SB game or the RB game ends. That is, the predetermined start prize may be shifted to a different game state instead of returning to the original game state even when the start prize is completed. In this case, the transition of the game state is as shown in FIG.

Here, the CPU 101 may return the game state to the first normal game when the RB game or the SB game ends on condition that the SB1 prize, the SB2 prize or the RB prize is won internally. In addition, the reels R1 to R3 may be stopped so as to be non-winning by the reel stop control in the game won in the SB1 prize or the SB2 prize. In this case, the CPU 101 selects the lost stop data table group TBL29 in S106e1 and S106f1 described above, and detects the winning of the SB1 award and the SB2 award in order to return to the first normal game from the next game. The normal game in-game flag 2 may be cleared.

Further, the CPU 101 detects the winning of the RB prize, the SB1 prize, and the SB2 prize in the second normal game, and indicates that the game has shifted to the first normal game after a predetermined number of games have passed. May be displayed on the liquid crystal display 30.

(3) In the embodiment and the modification described above, a plurality of BB prizes such as a BB1 prize and a BB2 prize may be provided. In this case, the winning modes corresponding to the BB1 award and the BB2 award are different from each other, and the acquisition quantity upper limit value may be different between the BB1 game and the BB2 game. More specifically, in the first base game, the lottery is executed by including the BB1 prize and the BB2 prize in the lottery object, and different acquisition quantity upper limit values are selected for the BB1 game and the BB2 game, and the selected acquisition quantity upper limit value is selected. And the counted number of acquisitions may be compared to end the BB game.

(4) In the above-described embodiment and modification, the second base game is set up by appropriately setting the winning probability of the internal lottery until the predetermined condition is satisfied from the next game in which the MB prize of the CB prize is won. It can be grasped as a game that is performed by changing the prize lottery probability or a game that is performed by continuously starting the CB game. In this case, the second normal game can be recognized as a game in which the accessory continuous operation device related to the second type special accessory is operating according to the game rules.

(5) In the embodiment and the modification described above, when the SB1 prize or the SB2 prize is won in the second base game, the second base game is ended. As a result, since the player cannot know the result of the internal lottery, there is an advantage that the player is not aware that the game state has changed. Further, in the internal lottery, by performing a lottery by combining the SB1 award or SB2 award and the specific small role award or replay award, the winning flag for the award combined with the SB award is set at the same time. A game that wins the prize and a game that wins only the prize to be combined, and the game that is stopped based on the stop operation has a commonality, and the player knows that the SB1 prize or SB2 prize is won You may make it hard to be done. Specifically, as shown in FIG. 25A, when the acquired random number value belongs to the range of numerical values specified by the lottery classification data indicated by “ADR11 + 08H”, the winning flag for only the SB1 prize is set. On the other hand, as shown in the prize lottery table of FIG. 5B, the winning flags of the SB1 prize and the small role B prize as the specific small role prize are set simultaneously. Alternatively, as shown in the prize lottery table of FIG. 10C, the winning flags for the SB1 prize and the replay prize are set simultaneously. The same applies to the SB2 award, but when there are a plurality of SB awards, such as a combination of the SB1 award and the small role B award (specific small role award) and a combination of the SB2 award and the replay award, the awards to be combined are the same You don't have to. In FIG. 4B, the small role B prize paired with the SB1 prize and the SB2 prize is small when the acquired random number value belongs to the range of numerical values specified by the lottery classification data indicated by “ADR11 + 00H”. Set the winning flag for only the role B prize. In FIG. 6C, the replay award paired with the SB1 award and the SB2 award is replayed when the acquired random number value belongs to the range of numerical values specified by the lottery classification data indicated by “ADR11 + 12H”. Set the winning flag for the award only. As described above, the award paired with the SB1 award or the SB2 award does not form a pair with the SB1 award or the SB2 award and has independent lottery classification data. The prize lottery table in FIG. 10B or FIG. 10C is used in the first base game and the second base game.

A game in which both the SB1 prize and the small part B prize as the specific small part prize are won will be described as an example. In a game where both the SB1 award and the specified small role award (the small role B award) are won, the symbols constituting the winning mode corresponding to the SB1 award at the timing of the first stop operation of the reel are within 4 frames from the winning line If the symbol constituting the winning mode corresponding to the SB1 prize is not located within 4 frames from the winning line at the timing of the stop operation, the stop operation is further performed. When the symbol (cherry symbol) constituting the winning mode corresponding to the specific small role award (small role B award) is located within 4 frames from the winning line, control is performed so that the symbol is drawn. In this way, in the game where both the SB1 prize and the specified small role prize (small role B prize) are won, 1) The symbols constituting the winning mode corresponding to the SB1 prize stop depending on the reel stop operation to be stopped first. 2) The symbols constituting the winning mode corresponding to the specific small role award are stopped, and 3) the symbols not corresponding to any award are stopped. When the specific small role award is composed of 100% winning symbols, the stop mode of 3) above is not included. If the symbols constituting the winning mode corresponding to the SB1 award cannot be stopped on the winning line as a result of the first reel stopping operation, the remaining reels are stopped corresponding to the SB1 award. Even if the symbols constituting the aspect can be stopped on the winning line, the symbols constituting the winning aspect corresponding to the specific small role award (small role B award) are set so as not to stop on the winning line. Control to stop. In this case, in the stop control of the remaining reels, a stop data table corresponding to a specific small role award (small role B award) may be selected instead of the stop data table corresponding to the SB1 award. By performing such stop control, it is possible to make the player think that the specific small role prize has been won and to make it difficult to detect that the SB1 prize has been won.

Further, the specified small role award is a small role award such as the small role B Award that has been missed, and the symbol constituting the winning mode corresponding to the SB1 award and the symbol configuring the winning mode corresponding to the specific small role award It is preferable to arrange so that the distance from (for example, cherry symbol) is more than 4 frames. In a game where the player is not notified of which prize has been won in the internal lottery, the player performs a stop operation aiming at a missed small role award so that he can win as many medals as possible. If it is not notified, the player does not switch from the specified small role award (small role B award) to the SB award and stops the game even if the SB1 award is won. Since the stop operation aiming at the award (small part B prize) is performed, the chance of winning the SB prize can be reduced.

Further, a game in which both the SB1 prize and the replay prize are won will be described as an example. In a game where both the SB1 prize and the replay are won, the symbols constituting the winning mode corresponding to the SB1 prize are positioned within 4 frames from the winning line at the timing of the reel stop operation to be stopped first. Also, control is performed so as to draw a symbol (plum symbol) constituting a winning mode corresponding to the re-game award. In this case, in all reel stop control, a stop data table corresponding to the re-game prize may be selected instead of the stop data table corresponding to the SB1 prize. By performing such stop control, it is possible to make the player think that the re-game prize has been won and to make it difficult to detect that the SB1 prize has been won.
