Description

  The present invention relates to a slot machine, and more particularly to a slot machine having a short-term advantageous state that lasts for a predetermined number of games and a long-term advantageous state that lasts for a number of games longer than the predetermined number of games.

  A slot machine generally includes a variable display device having a plurality of (usually three) reels having a plurality of types of symbols as identification information drawn on the outer periphery, and each reel has a start lever by a player. Rotation is started by operating, and when the player operates a stop button provided corresponding to each reel, the rotation is stopped within a range of a predetermined maximum delay time from the operation timing. . Then, a prize is generated according to the display mode derived when the rotation of all the reels is stopped.

  The types of winning combinations include small roles, bonuses, and replays. Here, in the winning of a small role, the player can obtain a profit that a predetermined number of medals are paid out for each type of small role. In the bonus winning, the player can obtain a profit that the next game is shifted to a gaming state advantageous to the player, such as a regular bonus or a big bonus. In the replay winning, it is possible to obtain a profit that the next game can be performed without consuming new medals for setting the number of bets.

  In order for a winning combination including a bonus combination to occur, generally, a winning flag must be set by winning an internal lottery performed in advance (usually when a start lever is operated). Here, using the fact that the player can obtain the benefit of not having to consume medals for setting the number of bets due to the replay winning, the RT winning is determined in advance by the symbol derived to the variable display device. A special game state called a bonus such as a big bonus or regular bonus is used to increase the replay winning probability without changing the winning probability of a role other than replay by the predetermined number of games. There is a slot machine that is determined as a gaming state advantageous to other players (see, for example, Patent Document 1).

  In games where the game state is controlled to RT, replay is won with a fairly high probability, and in games where replay is won, replay is usually preferentially derived even if a bonus is won. . In other words, when the gaming state is controlled to RT, it is difficult to win a bonus even if a bonus is won. Therefore, a continuous period that is executed over a plurality of game periods using the period controlled by RT. There has been a slot machine that performs an effect (see, for example, Non-Patent Document 1).

Japanese Patent Laying-Open No. 2005-131323 (paragraph 0035) Pachislot Strategy Magazine January 2003 (16, 17 pages)

  As described above, the RT in the conventional slot machine is an attempt to improve the interest of the game by providing a game state that is advantageous to the player other than the bonus as in Patent Document 1, As such, it was only intended to improve the interest of the game by performing a continuous production using the fact that it is difficult to win a bonus regardless of whether or not it was won. Even if there is a difference in whether or not the game can be advantageously advanced depending on whether or not the game state is controlled by RT, there is no strategy in the game.

  The present invention provides, as an advantageous state, a short-term advantageous state that lasts for a predetermined number of games and a long-term advantageous state that lasts for a number of games longer than the predetermined number of games. It is an object of the present invention to provide a slot machine that enhances technical intervention and increases game strategy by making it possible to avoid the transition according to the skill of the player.

To achieve the above object, a slot machine according to the present invention includes:
A game can be started by setting a predetermined number of bets for one game using a game value (medal), and a variable display device (variable display device 2) that displays a plurality of types of identification information in a variable manner. In the slot machine in which one game is completed by deriving the display result in) and winning can be generated according to the display result derived to the variable display device.
Specific display results (regular bonus, big bonus (1), big bonus (2), watermelon) and short-term advantageous display results (chance) are included before the display result of the variable display device is derived for each game. A pre-determining means (step S403) for determining whether or not to permit derivation of a plurality of types of display results;
Stop operation means (stop buttons 12L, 12C, 12R) operated by the player to stop the variation display of the identification information;
Derivation control means (step S404) for deriving the display result of the variable display device according to the operation procedure of the stop operation means and the determination result of the prior determination means when the stop operation means is operated;
Advantageous state control means (steps S815 and S916) for controlling the gaming state to an advantageous state (RT) that is more advantageous to the player than the normal gaming state ;
A plurality of types in which probabilities that the derivation of the winning display result is allowed to be determined by the predetermining means based on the operation of predetermined setting operation means (setting key switch 92, setting switch 91) are different for each set value. Setting value setting means (steps S201 to S210) for selecting and setting any one of the setting values (setting values),
Data storage means (RAM 112) for storing data for controlling the progress of the game including setting value data indicating the setting values set by the setting value setting means so as to be readable and writable;
Holding means for holding data for controlling the progress of the game stored in the data storage means even when power supply to the slot machine is interrupted;
The progress of the game held by the holding means without individually determining whether or not the set value data of the data for controlling the progress of the game is appropriate when the slot machine is powered on Stored data determination means (steps S105 and S106) for determining whether or not the data for controlling the data matches the data before power-off,
A first step of disabling the progress of the game when it is determined by the stored data determination means that the data for controlling the progress of the game held by the holding means does not match the data before the power-off. Disabling means (step S106 (NO), step S301),
The set value data is read from the data storage means every time a game start operation is performed, and the set value indicated by the read set value data is within a set value range that can be set by the set value setting means Setting value determination means for determining that the read set value data is appropriate and determining that the read set value data is not appropriate when it is not within the settable set value range (steps S508 and S509). When,
Second disabling means (step S509 (NO), step S301) for disabling the progress of the game when the set value determining means determines that the read set value data is not appropriate;
Based on the operation of the setting operation means, even when the progress of the game is disabled by the first disabling means and also when the progress of the game is disabled by the second disabling means. On the condition that the set value is newly set by the set value setting means, the disabled state cancellation means for canceling the state where the progress of the game is disabled and enabling the progress of the game (step S111, FIG. 11)
When the predetermining unit determines that the read set value data is appropriate by the set value determining unit, a winning display result in the game with a probability corresponding to the set value indicated by the read set value data And determining whether to permit the derivation of the specific display result is also determined to permit the derivation of the short-term advantageous display result at the same time,
The advantageous state control means includes:
When a predetermined short-term advantageous display result (chance) is derived as a display result of the variable display device, a short-term advantageous state (short) that continues for a predetermined number of games (three games) among the advantageous states. RT) short-term advantageous state control means for controlling the gaming state (step S815),
When a predetermined long-term transition condition is established, the game continues for the number of games (100 games) longer than the predetermined number of games in the advantageous state, and the profit obtained by the player by the end is Long-term advantageous state control means (step S906) for controlling the gaming state to a long-term advantageous state (long RT) larger than the short-term advantageous state;
When the short-term advantageous display result is derived in the long-term advantageous state, the long-term advantageous state is terminated and the gaming state is controlled to the short-term advantageous state (in step S815, the value of the RT counter so far is related). First, set 4 as the initial value of the RT counter)
The derivation control means includes
First procedure time derivation means for deriving the specific display result when the stop operation means is operated in the first procedure when it is determined that the derivation of the specific display result and the short-term advantageous display result is permitted. (FIGS. 2, 8, and 9),
When it is determined that the derivation of the specific display result and the short-term advantageous display result is permitted, the short-term advantageous display result is displayed when the stop operation means is operated in a second procedure different from the first procedure. Second procedure time deriving means (FIGS. 2, 8, and 9) for deriving,
The slot machine is
When it is determined by the pre-determining means that the derivation of the specific display result and the short-term advantageous display result is permitted in the game controlled to the long-term advantageous state, predetermined information (SRT possibility notification) is provided. It further comprises information notification means for notification (step S1007).

  In the slot machine, when controlled to the advantageous state, the player can advance the game more advantageously than the normal gaming state, and this advantageous state includes a short-term advantageous state that continues for a predetermined number of games. There is a long-term advantageous state that lasts for a longer number of games. Even when the long-term advantageous state is controlled, if the short-term advantageous display result is derived, the gaming state is controlled to the short-term advantageous state, and the number of games as the entire advantageous state may be reduced. When the long-term advantageous state is controlled, it may be advantageous for the player not to derive the short-term advantageous display result.

Here, the reason why the short-term advantageous display result is derived as the display result of the variable display device is that it is determined that the derivation of the specific display result and the short-term advantageous display result is permitted, and the stop operation means is the second procedure. Only when operated. If it is determined that the derivation of the specific display result and the short-term advantageous display result is permitted in the long-term advantageous state , predetermined information (substantially, the short-term advantageous state can be obtained by operating the stop operation means in the second step. since but so that the indicating derived) is informed, it can be determined whether it is sufficient to operate the stop operation means in any operating procedures. Thereby, the player's technical intervention is maintained for maintaining the long-term advantageous state, and the strategy of the game is enhanced, so that the interest of the game can be improved.

  Conventionally, when the data stored in the data storage means (RAM) in the slot machine has been corrupted and the game cannot be progressed, the data in the data storage means is initialized by a predetermined reset operation. It was released after being released, and the progress of the game was resumed. Here, when the data in the data storage means is initialized by the reset operation, the default setting value (usually, the setting value with the lowest probability that it is determined that the derivation of the winning display result is permitted) is automatically set. Was to be selected. For this reason, the pre-determining means may not be determined with the probability that the amusement store has intended. Especially when the setting value with the lowest probability is automatically selected, it is disadvantageous for the player. There was a problem that would become larger.

  On the other hand, when the data stored in the data storage means does not match the data before the power is turned off, the game cannot be progressed properly because the game cannot be progressed properly. It is necessary to initialize the data stored in the data storage means in order to cancel the state where the progress of the game is impossible here. In this case, the data indicating the set value is also initialized. End up. However, in the slot machine, when the game cannot be advanced based on the fact that the data stored in the data storage means does not match the data before the power is turned off, a new set value is set based on the operation of the setting operation means. If not, it will not be released. For this reason, since it is ensured that the game is played based on the newly set value, the fairness of the game can be achieved.
  Further, when the determination is made by the prior determination means, the setting value data stored in the data storage means is read out, and it is determined whether or not the setting value indicated by the setting value data is within an appropriate range. If the set value is not within an appropriate range, the game cannot be progressed properly because the game cannot be progressed properly. Here, the state where the progress of the game is disabled based on the fact that the setting value indicated by the setting value data stored in the data storage means is not within the proper range is newly set based on the operation of the setting operation means. If the value is not set, it will not be released. For this reason, since it is ensured that the game is played based on the newly set value, the fairness of the game can be achieved.

The short-term advantageous state and the long-term advantageous state may be the same advantageous state except for the number of continuing games until the end. In this case, when the number of remaining games in the long-term advantageous state is larger than the number of games in the short-term advantageous state, the profit that the player can obtain in the remaining games in the long-term advantageous state is obtained in the short-term advantageous state. Greater than profit.
In addition, the pre-determining unit determines whether or not to permit the derivation of a re-game display result (replay) that allows a next game to be played without using a gaming value for setting the bet amount. Where
The advantageous state may be, for example, a replay high probability state in which a probability of determining that the derivation of the replay display result is permitted is higher than that in the normal game state.
Further, there may be a plurality of types of specific display results. Here, the first procedure for deriving the specific display result when it is determined that the derivation of the specific display result is allowed may be different for each type of the specific display result. The second procedure may be all the operation procedures other than the first procedure among the operation procedures of the stop operation means, or may be a part of the operation procedures other than the first procedure. .

In addition, the information notification means is provided on the condition that in the game controlled to the long-term advantageous state, the profit obtained during the remaining number of games in the long-term advantageous state is larger than the profit obtained in the short-term advantageous state. The predetermined information may be notified. On the other hand, although the information notification means notifies the predetermined information in the game controlled to the long-term advantageous state, the profit obtained during the remaining number of games in the long-term advantageous state is obtained in the short-term advantageous state. When the profit is smaller than the profit, information indicating that can also be notified. In these cases, it is actually better to derive the short-term advantageous display result, but the player intentionally removes the short-term advantageous display result without operating the stop operation procedure in the second step. There will be no need.

In the above slot machine,
The pre-determining means includes a special display result (regular bonus, big bonus (1), big bonus (2) with a transition to a special gaming state (regular bonus, big bonus) advantageous to a player different from the advantageous state. )) And whether to allow the derivation of the re-game display result (replay) that allows the next game to be played without using the gaming value in the setting of the bet number,
The short-term advantageous state control means controls the gaming state to a re-gaming high probability state (RT) that increases the probability of determining that the derivation of the re-game display result is allowed as compared with the normal gaming state as the short-term advantageous state. May be.
In this case, the slot machine is
Special decision carry-over means (step S914) for carrying over the decision to allow the derivation of the special display result until the special display result is derived based on the decision to permit the derivation of the special display result;
Special gaming state control means (steps S808, S810, S812) for controlling the gaming state to the special gaming state when the special display result is derived as the display result of the variable display device;
An effect execution means for executing a predetermined effect (continuous effect) after the special display result is not derived based on the decision to permit the derivation of the special display result and after the short-term advantageous display result is derived. (Step S1010) can further be provided,
The derivation control means is configured to re-execute the re-display than the special display result when it is determined that the derivation of the re-game display result is permitted in a state where the determination to permit the derivation of the special display result is carried forward. It may further include a re-game priority deriving means for deriving the game display result as a display result of the variable display device with priority.

  Here, a predetermined effect is executed after it is determined that the derivation of the special display result is allowed and after the advantageous display result is derived. In other words, the fact that the predetermined effect has been executed means that it may be determined that the derivation of the special display result is permitted. Therefore, the player can derive the special display result by the predetermined effect. It is possible to give a sense of expectation that it has been decided to allow, and to improve the interest of the game.

  In addition, after the short-term advantageous display result is derived, there is a high probability that it is determined that the re-game display result is allowed to be derived during a predetermined number of games that are controlled in the short-term advantageous state, that is, the high replay probability state. Even if it is determined that the derivation of the special display result is permitted, the possibility that the special display result is derived is reduced. When the replay high probability state is applied to the long-term advantageous state, the re-game display result is often derived even in a game after it has been determined that the special display result can be derived in the long-term advantageous state. . When it is determined that the derivation of the special display result is permitted (or when all the display results derived by the omission of the special display result are derived), the game is replayed even if the advantageous display result is not derived. It is also possible to control to a high probability state (including a case where a replay display result as a long-term advantageous state is continued).

  In such a case, even if it is determined that the derivation of the special display result is permitted, the special display result is not derived anyway in many games where the derivation of the replay display result is permitted. Can be carried out effectively. In addition, if it is determined that allowing the derivation of the special display result may not be determined in the same game as allowing the derivation of the replay display result, a winning display including the regame display result as the display result of the variable display device When the result is not derived, there is a possibility that it is determined that the derivation of the special display result is allowed in the game, and the player's expectation can be increased. However, even if it is determined that the derivation of the special display result is permitted, even if the replay high probability state is not controlled, the player may be allowed to derive the special display result by executing the predetermined effect. The effect of expecting to be decided remains unchanged.

  The predetermined effect may be an effect for only one game, or may be a continuous effect that is continuously executed for a plurality of games. In the case of a continuous production, the production may be temporarily stopped at the end of one game, and the result of the production may be shown when the number of bets is set for the next game. In this way, by making the predetermined effect as a continuous effect over the game, the player has a sense of expectation for the decision to allow the derivation of the special display result for a relatively long period of time, not a single game unit but a plurality of games. Since it can be given to the game, the interest of the game can be improved.

The specific display result may include the special display result or may not include the special display result. Further, the specific display result may include a small combination display result (watermelon) accompanied by the addition of the game value. When the specific display result includes the special display result, when the special display result is not derived based on the determination that the special display result is allowed to be derived, the display result other than the special display result is displayed. Even if the predetermined effect is executed regardless of whether or not the advantageous display result is derived, the predetermined display is performed on the condition that the advantageous display result is derived as a display result other than the special display result. It is good also as what performs a production.

Here, when the special display result is included in the specific display result , the short-term advantageous display result may be derived by missing the special display result and controlled to the short-term advantageous state. Therefore, it is possible to give the player a sense of expectation that it is determined that the derivation of the special display result is permitted in the derivation of the short-term advantageous display result. If the special display result includes both the special display result and the small role display result, if the short-term advantageous display result is derived, the possibility of the special display result being missed and the small role display result being missed Therefore, it is possible to give the player a reasonable expectation that it has been decided to allow any derivation, and to improve the interest of the game.

Furthermore, when the special display result (and the small role display result) is included in the specific display result , the display derived by missing the special display result (and / or the small role display result) including the short-term advantageous display result Since a role other than information merely informing the player of the possibility of allowing the derivation of the special display result to be given to the result is given, it is possible to improve the gameability.

In this case, the slot machine is
When a predetermined special end condition (payout exceeding 465 cards) is established after being controlled to the special gaming state (big bonus), the special gaming state is ended and the gaming state is controlled to the long-term advantageous state. Special game state ending means (step S906) may be further provided.

  By making the gaming state controlled after the end of the special gaming state a long-term advantageous state, it is possible to suppress the decrease in the gaming value possessed by the player after the end of the special gaming state (while increasing in some cases) Since the number of cases in which a special gaming state can be reached increases, the player's expectation can be enhanced and the interest of the game can be improved.

In this case, in the slot machine,
The pre-determining means includes
When determining that the derivation of the special display result is allowed, it is further determined that the derivation of the third display result different from the special display result, the specific display result, and the short-term advantageous display result is allowed ,
When determining that the derivation of the specific display result and the short-term advantageous display result is allowed, it is further determined that the derivation of the third display result is allowed,
The derivation control means includes
When it is determined that the derivation of the special display result and the third display result is permitted, the special display result is derived when the stop operation means is operated in a special procedure, and the stop operation means Special permissible time deriving means for deriving the third display result when operated in a non-special procedure different from the special procedure;
When it is determined that the derivation of the specific display result , the short-term advantageous display result, and the third display result is permitted, the stop operation means is operated in a third procedure different from the first procedure and the second procedure. And a third procedure time deriving means for deriving the third display result when it is performed,
In this case, the slot machine is
When the third display result is derived in the game controlled to the long-term advantageous state, a special effect (chance effect) indicating whether or not the derivation of the special display result is permitted is executed. It is possible to further include special effect execution means (step S1017).

Here, even if it is not possible to derive the special display result and shift the gaming state to the special gaming state, it is determined that the derivation of the special display result is still allowed when the third display result is derived. It can happen. A special effect performed in such a case can give the player a sense of expectation that the derivation of the special display result is permitted, so that the interest of the game can be further improved. . Even when it is determined that the derivation of the specific display result is permitted, the third display result is derived, so that the player's expectation for maintaining the gaming state in the long-term advantageous state can be enhanced. Furthermore, the interest of the game can be improved.

When the specific display result includes the special display result, the special procedure is the first procedure, and the non-special procedure is the second procedure. If the specific display result includes a special display result and a winning display result other than the special display result, the special effect indicates that derivation of the special display result may be permitted, so-called notice If the specific display result includes only the special display result, the special effect is a so-called notification effect that definitely indicates that the derivation of the special display result is permitted. In either case, the player can be given a sense of expectation that it has been determined that the derivation of the special display result is allowed.

In the above slot machine,
The pre-determining means determines whether or not to permit derivation of a small combination display result (watermelon) accompanied by a predetermined number (9) of game value as the specific display result ,
The information notification means, when the instruction to permit the derivation of the specific display results with the short-term beneficial results are displayed is determined by the predetermination means even in a game which is controlled in the normal gaming state, the predetermined information You may notify. In this case, the slot machine is
When the small combination display result is derived as the display result of the variable display device, the difference between the number of games that can be executed with the predetermined number of game values (3 games) and the predetermined number of games is less than 1 (0) It is possible to further include game value providing means (step S902) for providing the player with a number of game values.

In this case, when predetermined information is notified from the information notification means, the player may not be able to determine whether the game state is normal or advantageous. If the stop operation means is operated so that the short-term advantageous display result is not derived in the normal gaming state, the player loses the profit due to the short-term advantageous state. However, if the stop operation means is operated in the first procedure, the small role display result can be derived, and the profit in the short-term advantageous state lost due to the game value provided thereby can be maintained. It will not be disadvantageous to you.

In the above slot machine,
The variable display device rotates display bands (reels 3L, 3C, and 3R) each having a plurality of types of identification information that can be identified by driving a stepping motor (reel motors 3ML, 3MC, and 3MR). A display result may be derived from each of a plurality of variable display units capable of variably displaying. in this case,
The stop operation means is provided in correspondence with each of the plurality of variable display sections, and is operated by a plurality of stop operation means (stop buttons 12L, 12C, 12R) that are respectively operated when deriving display results in the corresponding variable display sections. ).

Here, the derivation control means is
In a situation where a display result has not yet been derived for any of the plurality of variable display units, a variable display unit for which a display result has not yet been derived is displayed at the time when the stop operation means corresponding to the variable display unit is operated. From a plurality of control patterns (FIG. 9: stop control table) that uniquely specify a display result derived with respect to the number of steps of the stepping motor, a control pattern corresponding to the determination result of the predetermining means is uniquely set Control pattern selection means (step S705) for specifying
When the stop operation unit corresponding to the variable display unit for which the display result has not yet been derived is operated, the control pattern selected for the variable display unit by the control pattern selection unit is the step at the time of operation of the stop operation unit The display result uniquely specified for the number can be derived as the display result in the variable display unit (step S715).

  In this case, the step of the stepping motor at the time when the stop operation means is operated for the variable display unit for which the display result has not been derived yet in the situation where the display result has not yet been derived for all of the plurality of variable display units. The control pattern corresponding to the combination of the determination results of the predetermining means of the game is uniquely selected from the plurality of control patterns that uniquely specify the display result derived for the number, and the corresponding variable display unit Control for deriving the display result is performed. That is, there is only one control pattern that is applied to one determination result of the prior determination means. For this reason, there is no need to further select any one control pattern from a plurality of control patterns with respect to one determination result of the prior determination means as in the prior art by lottery or the like different from the prior determination means. The control for deriving the display result is not complicated.

The derivation control means includes
In a situation where a display result is derived to at least one of the plurality of variable display sections and a display result is not derived to another variable display section, the variable display section for which the display result has not been derived yet From a plurality of control patterns (FIG. 9: stop control table) that uniquely specify the display result derived with respect to the number of steps of the stepping motor at the time when the stop operation means corresponding to the section is operated Control pattern selection means (step S705) for uniquely identifying the control pattern corresponding to the number of steps when the corresponding stop operation means is operated in the variable display section for which the determination result of the determination means and the display result has already been derived. Including
When the stop operation unit corresponding to the variable display unit for which the display result has not yet been derived is operated, the control pattern selected for the variable display unit by the control pattern selection unit is the step at the time of operation of the stop operation unit The display result uniquely specified for the number can be derived as the display result in the variable display unit (step S715).

Alternatively, the derivation control means includes
In a situation where a display result is derived to at least one of the plurality of variable display sections and a display result is not derived to another variable display section, the variable display section for which the display result has not been derived yet From a plurality of control patterns (FIG. 9: stop control table) that uniquely specify the display result derived with respect to the number of steps of the stepping motor at the time when the stop operation means corresponding to the section is operated Control pattern selection means (step S705) for uniquely identifying a control pattern corresponding to the combination of the determination result of the determination means and the display result in the variable display unit from which the display result has already been derived,
When the stop operation unit corresponding to the variable display unit for which the display result has not yet been derived is operated, the control pattern selected for the variable display unit by the control pattern selection unit is the step at the time of operation of the stop operation unit A display result uniquely specified for the number can be derived as a display result in the variable display unit (step S715).

  In these cases, the display results are still derived in any one of the plurality of variable display sections, and the display results are not yet derived in the other variable display sections. From the plurality of control patterns that uniquely specify the display result derived with respect to the number of steps of the stepping motor at the time when the stop operation means is operated for the variable display unit from which the stop operation means is operated, The control pattern corresponding to the combination of the display results of the variable display section from which the display results have already been derived (or the number of steps when the corresponding stop operation means is operated in the variable display section from which the display results have already been derived) is unique. Control is performed so that the corresponding variable display unit derives the display result. That is, the combination of the determination result of the predetermining means and the display result of the variable display section for which the display result has already been derived (or the number of steps when the corresponding stop operation means is operated in the variable display section for which the display result has already been derived) ) Has only one control pattern applied. For this reason, it is not necessary to further select any one of the plurality of control patterns, and the control for deriving the display result of the variable display device is not complicated.

The slot machine is
Predetermined for a special game (regular bonus) in which, when a predetermined special condition is established, the pre-determining means determines with higher probability than the game in the normal gaming state that the derivation of the small role display result is allowed Special game control means (steps S503 and S812) for controlling the period may be provided.

Here, the slot machine further includes special game determination means (step S502) for determining, for each game, whether or not the special game is controlled in the special state.
The special game control means may start control of the special game as establishment of the special condition when it is determined by the special game determination means that the special game is not controlled (step) S503).

  In this case, whether to control to a special game for the first time after derivation of the special state display result, or to control to a special game again when the special game period has ended and the special state has not ended yet, The same processing can be performed.

  Further, the special game control means starts controlling the special game as the special condition is satisfied when the special condition is controlled, and starts the control of the special game in the special state. When the predetermined period expires and the control of the special game is finished, the special game can be resumed as the special condition is satisfied (variation: at the end of the big bonus, the regular bonus Set regular bonus medium flag at the end).

  In this case, when the special game period ends and the special state has not ended yet, the special game can be immediately returned to.

In the above slot machine,
The pre-determining means determines whether to permit the derivation of both the special display result and the small role display result in one game (FIG. 5 (b), (c): regular bonus + watermelon, Big Bonus (1) + Watermelon, Big Bonus (2) + Watermelon).

  If it is determined that the derivation of both the special display result and the small role display result is allowed in this way, the special display result is derived by deriving the small role display result as the display result of the variable display device.

  FIG. 3 is a diagram showing the configuration of the control circuit of the slot machine 1. As shown in the figure, the control circuit of the slot machine 1 includes a power supply board 100, a game control board 101, an effect control board 102, a reel relay board 103, a reel lamp relay board 104, an external output board 105, and an effect relay board 106. It is divided roughly.

  The power supply board 100 transforms an external power supply voltage of AC 100V and supplies operating power to the game control board 101 and other parts of the slot machine 1. In FIG. 3, it is shown that only the game control board 101, the hopper 80, and each of the switches 91 to 94 are connected, but the power supply board 100 also supplies power to other parts. The power supply board 100 is provided in the slot machine 1 and is connected to a hopper 80 that includes a hopper motor 82 that performs a medal payout operation and a payout sensor 81 that detects a medal payout operation.

  The power supply board 100 sets a winning probability for an internal lottery to be described later, and a setting switch 91 and a setting switch 91 for changing setting values (setting 1 to setting 6) of medal payout rates calculated based on the probability. Are connected to a setting key switch 92 for enabling the operation, a second reset switch 93 for resetting the internal state (RAM 112), and a main switch 94 for switching the power ON / OFF, and detection of these switches. A signal is sent to the game control board 101. These switches 91 to 94 are provided inside the slot machine 1.

  The game control board 101 is a control board on the main side that controls the overall flow of the game in the slot machine 1, and includes a control unit 110 including a CPU 111, a RAM 112, a ROM 113, and an I / O port 114. It is installed. Further, a random number generation circuit 115, a sampling circuit 116, a power supply monitoring circuit 117, a reset circuit 118, and other circuits are mounted.

  The CPU 111 has an interrupt function (including an interrupt prohibition function) such as a timekeeping function and a timer interrupt, and executes a program (described later) stored in the ROM 113 to perform processing related to the progress of the game, and in the slot machine 1 Control each part of the control circuit directly or indirectly. One word of data handled by the CPU 111 is 8 bits (1 byte), and the addresses of the RAM 112 and the ROM 113 are also assigned in units of 8 bits.

  The RAM 112 is used as a work area when the CPU 111 executes a program. The ROM 113 stores programs executed by the CPU 111 and fixed data. The allocation of the addresses of the RAM 112 and the ROM 113 is different between the development model in the manufacturer and the mass production model delivered to the hall. The I / O port 114 inputs and outputs control signals to and from each circuit connected to the game control board 101.

  The RAM 112 uses a DRAM (Dynamic RAM) and requires a refresh operation to maintain the stored data contents. The CPU 111 is provided with a refresh register for performing this refresh operation. The refresh register is composed of 8 bits, which is the size of one word, and the lower 7 bits are automatically incremented every time the CPU 111 fetches an instruction from the ROM 113, and the value is updated by 1 instruction. It is performed at every execution time.

  The random number generation circuit 115 is configured by a counter that counts up and updates the value every time a predetermined number of pulses are generated, as will be described later, and the sampling circuit 116 acquires the numerical value counted by the random number generation circuit 115. . The random number generation circuit 115 is provided for each type of random number used for the progress of the game, and a range of numerical values to be counted for each type of random number is determined. The CPU 111 sends an instruction to the sampling circuit 116 according to the processing to acquire the numerical value indicated by the random number generation circuit 115 as a random number (hereinafter, this function is referred to as a hardware random number function). As a random number for internal lottery described later, a numerical value obtained by processing a numerical value extracted by the hardware random number function by software is used.

  The power monitoring circuit 117 monitors the power supply voltage supplied from the power supply substrate 100, and outputs a voltage drop signal to the control unit 110 when detecting a voltage drop. Although not particularly shown, the control unit 110 includes an interrupt input terminal connected to the power supply monitoring circuit 117, and an external interrupt is generated in the CPU 111 when a voltage drop signal is input to the interrupt input terminal. The CPU 111 executes a power interruption process described later.

  The reset circuit 118 outputs a reset signal when the voltage rises to a level at which the control unit 110 can be activated when the power is turned on to start the control unit 110, and generates a signal periodically output from the control unit 110. When the count is incremented without being cleared based on the reset counter, that is, when the control unit 110 does not operate for a certain time, a reset signal is output to the control unit 110 and the control unit 110 is restarted. .

  The CPU 111 also has a function of updating the numerical value of the specific address in the RAM 112 by timer interrupt processing and acquiring the updated numerical value as a random number (hereinafter, this function is referred to as a software random number function). The CPU 111 transmits various commands to the effect control board 102 via the I / O port 114. Note that information (commands) is sent from the game control board 101 to the effect control board 102 only in one direction, and no information (commands) is sent from the effect control board 102 to the game control board 101.

  Connected to the game control board 101 are a single BET switch 45, a MAXBET switch 46, a start switch 41, stop switches 42L, 42C, 42R, a settlement switch 47, a first reset switch 48, and a throw-in medal sensor 44. Detection signals from the switches / sensors are input. In addition, detection signals of the reel sensors 3SL, 3SC, and 3SR are input via the reel relay substrate 103. In accordance with the detection signals of these switches / sensors input via the I / O port 114 or the detection signals of various switches input via the power supply board 100 as described above, the CPU 111 on the game control board 101 Processing is in progress.

  The game control board 101 also includes a flow path switching solenoid 49, a game number display 51, a credit display 52, a payout display 53, a loading instruction lamp 59, a single betting lamp 54, two betting lamps 55, 56, Three betting lamps 57 and 58, a game over lamp 63, a start lamp 60, a replay lamp 62, BET button lamps 70a and 70b, and operation valid lamps 63L, 63C, and 63R are connected, and the CPU 111 follows the progress of the game. These operations are controlled.

  The game control board 101 is connected to reel motors 3ML, 3MC, and 3MR via a reel relay board 103. The CPU 111 controls the reel motors 3ML, 3MC, 3MR via the reel relay substrate 103 and stops the reels 3L, 3C, 3R with reference to a winning flag set in the RAM 112 by an internal lottery described later. An effect control board 102 is further connected to the game control board 101 via an effect relay board 106.

  The effect relay board 106 is a board provided to ensure one-way information transmitted from the game control board 101 to the effect control board 102. The effect relay board 106 does not check the game control board 101 and the effect control board 102 by checking this state, and an illegal signal (especially an external input to the effect control board 102 is input to the control unit 110 of the game control board 101). It is possible to check whether or not a modification has been made such that a signal is input).

  The effect control board 102 is a sub-side control board that controls the execution of effects in the slot machine 1, and is equipped with a control unit 120 including a one-chip microcomputer including a CPU 121, a RAM 122, a ROM 123, and an I / O port 124. Yes. In addition, the random number generation circuit 125 and the sampling circuit 126 are mounted, and the CPU 121 obtains the value counted by the random number generation circuit 125 by the sampling circuit 126, so that the hardware random number function similar to that of the game control board 101 is obtained. Is forming. It also has a software random number function by interrupt processing.

  The CPU 121 executes a program (described later) stored in the ROM 123 to perform processing related to the execution of the effect, and controls each circuit in the effect control board 102 and each circuit connected thereto. The performance is performed based on a command received from the game control board 101 via the I / O port 124. The RAM 122 is used as a work area when the CPU 121 executes a program. The ROM 123 stores programs executed by the CPU 121 and fixed data. The I / O port 124 inputs and outputs control signals to and from each circuit connected to the effect control board 102.

  The effect control board 102 is connected with game effect lamps 75A to 75M, a liquid crystal display 4, speakers 7L, 7R, and 7U, a fluorescent lamp 6, a weight lamp 61, and a bonus notification lamp 66. A reel lamp 3LP is connected via a reel lamp relay substrate 104. The control unit 120 of the effect control board 102 performs these effects by controlling these parts.

  The reel relay board 103 relays between the game control board 101, the external output board 105 and the reel unit 3. The reel relay substrate 103 is also connected with a full sensor 90, and its detection signal is input. The full tank sensor 90 is provided inside the slot machine 1 and detects that the medals in the overflow tank storing the medals overflowed from the hopper 80 are full.

  The reel lamp relay board 104 relays between the effect control board 102 and the reel unit 3. The external output board 105 is connected to an external device such as a hall management computer and receives a big bonus medium signal, regular bonus medium signal, reel control signal, stop signal input from the game control board 101 via the reel relay board 103. The switch signal, medal IN signal, medal OUT signal, and winning status signal are output to the external device.

  Next, the configuration of the RAM 112 of the game control board 101 will be described. FIG. 4 is a diagram showing the configuration of the storage area of the RAM 112. As shown in the figure, the RAM 112 stores an important work 112-1, a general work 112-2, a special work 112-3, a set value work 112-4, a non-saved work 112-5, a stack area 112-6, and a parity storage. A plurality of storage areas including the area 112-7 are provided.

  Among these storage areas, in particular, the set value work 112-4 is an area for storing a set value for determining a winning probability of internal winning to be described later, and the parity storage area 112-7 is a RAM parity at the time of power-off. Is an area for storing An area for setting a winning combination flag to be described later is provided in the general work 112-2. The RAM 112 is supplied with power from a backup power source even in the event of a power failure, and stores stored data.

  In the slot machine 1, the medal payout rate changes according to the set value, and the winning probability of the internal lottery described later is determined according to the set value. The medal payout rate is calculated by the ratio of the expected value of the number of medals that will be paid out to the small role won in the internal lottery described later to the number of medals that the player inserts to set the number of bets Is done. It is not calculated based on the number of medals that will be paid out for the small role that is actually won. As will be described later, when the gaming state is different, the medal payout rate also changes.

  Here, a setting value changing operation by the setting switch 91 will be described. In order to change the setting value, it is necessary to turn on the power of the slot machine 1 by the main switch 94 after the setting key switch 92 is turned on. When the slot machine 1 is started without changing the setting value, the setting key switch 92 may be turned off and the power may be turned on by the main switch 94.

  When the setting key switch 92 is turned on and the power is turned on, a setting change mode in which a setting value can be changed is entered. When the setting switch 91 is operated in the setting change mode, the setting value is updated one by one (when further operation is performed from the setting 6, the setting is returned to the setting 1). Then, when the setting key switch 92 is turned OFF after the start lever 11 is operated, the determined setting value after the change is stored in the setting value work 112-4. And it transfers to the state which can advance a game in a normal game state.

  When the game can be progressed, the games in the slot machine 1 progress one game at a time, but the set value stored in the set value work 112-4 in the internal lottery performed in each game is within the normal range (1 -6) and whether the number of bets is within a normal range (1 for regular bonus, 3 for other). When the set value is not within the normal range, it is determined that the RAM is abnormal, and a RAM abnormal error code is set and controlled to a RAM abnormal error state to disable the progress of the game.

  Further, when the CPU 111 of the game control board 101 detects the voltage drop signal, the power interruption processing is executed. In the power interruption processing, the RAM parity is calculated based on all data other than the data stored in the parity storage area 112-7 of the RAM 112, and stored in the parity storage area 112-7. ing. Here, the RAM parity is the least significant bit of the sum total of data strings (bits at the same position in each address).

  When the control unit 110 of the game control board 101 is activated, the RAM parity is calculated based on all data other than the data stored in the parity storage area 112-7 among the data stored in the RAM 112. Compared with the RAM parity stored in the parity storage area 112-7. If the comparison results match, the state before power-off is restored based on the state stored in the RAM 112.

  On the other hand, if the comparison result of the RAM parity does not match, it is determined that the RAM is abnormal again, and the RAM abnormal error code is set to control the RAM abnormal error state, thereby making the progress of the game impossible. ing. Unlike the other error states, the RAM abnormal error state is not canceled even if the first reset switch 48 or the second reset switch 93 is operated, and a new set value is set in the setting change mode. It comes to be canceled by this.

  In the slot machine 1, a winning is awarded when the winning symbols are arranged on any winning line of the variable display device 2. The types of winning combinations are determined according to the gaming status, but can be broadly divided into special roles with transition to special gaming status (regular bonus, big bonus) and small roles with payout of medals. There is a re-player who can start the next game without setting the bet amount. FIG. 5A is a view for explaining the combination of the types of winning combinations in the slot machine 1 and the symbols in the variable display device 2.

  The regular bonus is awarded when the combination of “BAR-watermelon-watermelon” is aligned on any of the winning lines (5) in the normal gaming state or RT. When the regular bonus is won, the gaming state shifts from the normal gaming state to the regular bonus. The regular bonus ends when 12 games are consumed, or when 8 games are won (any kind of combination is possible), whichever comes first. While the gaming state is in the regular bonus, the regular bonus medium flag is set in the RAM 112 (including the case where it is provided during the big bonus described below).

  The big bonus (1) is won when a combination of “7-watermelon-watermelon” is arranged in any of the winning lines (five) in the normal gaming state or RT. The big bonus (2) is won when a combination of “7-watermelon bell” is arranged in any of the winning lines (five) in the normal gaming state or RT. When the big bonus (1) and the big bonus (2) are won, the gaming state shifts to the big bonus.

  In the big bonus, the regular bonus described above is repeatedly provided until the end. While the gaming state is the big bonus, the big bonus medium flag is set in the RAM 112. The big bonus ends when the number of medals paid out to the player exceeds 465. Here, since the maximum payout number per game is 15, the upper limit of the payout medal number in the big bonus is 480. After the end of the big bonus, the gaming state is controlled to RT (long RT) that continues for 100 games. However, when the regular bonus, the big bonus (1) or the big bonus (2) is won, even if the prescribed number of games remains, the RT is terminated at that time.

  Even if a regular bonus, a big bonus (1) or a big bonus (2) is won in an internal lottery to be described later, “7” and “BAR” are arranged at intervals of 5 frames or less for the left reel 3L. However, at least the reel 3L can operate the stop button 12L at the timing when the “7” or “BAR” is stopped at either the upper, middle, or lower level, and the stop buttons 12L, 12C, and 12R can be awarded to these roles. If you do not follow the proper operating procedure, you will not win any of these roles.

  Of course, if the winning combination is not performed and the winning combination (for example, cherry-watermelon-watermelon) may be derived. When the operation procedure of the stop buttons 12L, 12C, 12R (especially the operation timing of the stop button 12L) cannot pull the “cherry” and the chance cannot be derived, the reach eye (for example, JAC-watermelon-watermelon) is derived. (Including the case of winning along with watermelon). In other words, when the chance bonus and the reach bonus are won for the regular bonus, the big bonus (1), or the big bonus (2), derivation is permitted as a display result of the variable display device 2 together with the display mode of each combination. That is, the display mode.

  A watermelon is awarded when a combination of “watermelon-watermelon-watermelon” is aligned on any winning line (5 or 1) in any gaming state, and nine medals are paid out. “Watermelons” for the reels 3C and 3R are arranged at intervals of 5 frames or less. However, there is only one “watermelon” for the reel 3L, and “watermelon” is a winning line depending on the operation timing of the stop button 12L. Can't stop on top. Even if a watermelon is won in an internal lottery to be described later, if the operation procedure of the stop buttons 12L, 12C, and 12R is not operated according to an appropriate operation procedure, the watermelon will not be won.

  However, even in this case, chances (for example, cherry-watermelon-watermelon) may be derived. When the “cherry” cannot be pulled in due to the operation procedure of the stop buttons 12L, 12C, 12R (especially the operation timing of the stop button 12L) and the chance cannot be derived, the losing eye (for example, bell-watermelon-watermelon) is derived. . In other words, the chance eyes and the losing eyes are display modes in which derivation is permitted as a display result of the variable display device 2 together with the display mode of “watermelon-watermelon-watermelon” when the watermelon is won.

  The chance is a display mode that can be derived only by regular bonus, big bonus (1) or big bonus (2), or by dropping a watermelon. The chance is not a winning display mode, but a display mode indicating the possibility of winning the regular bonus, the big bonus (1), or the big bonus (2). Further, when the chance is derived, the gaming state is controlled to RT (short RT) that continues for three games from there. Even if there are more than 4 games remaining in the long RT, since the gaming state is controlled to RT, the number of RT remaining games from there is 3 games.

  A bell is awarded when a combination of “bell-bell-bell” is arranged on any winning line (5 or 1) in any gaming state, and 15 medals are paid out. Since the “bells” are arranged at intervals of 5 frames or less for all of the reels 3L, 3C, 3R, when a bell is won in an internal lottery to be described later, the bell is always won.

  Cherry will be awarded when the “Cherry” symbol is derived on any of the winning lines (5 or 1) for the left reel 3L in any gaming state. Medals will be paid out. In the gaming state other than the regular bonus, when “Cherry” is stopped at the upper or lower stage of the left reel 3L, it is derived from two pay lines, so a total of four medals are paid out.

  Replay is awarded when a combination of “JAC-JAC-JAC” is aligned on any of the winning lines (five) in the normal gaming state or RT. With regular bonuses (including those inside big bonuses), even if this combination is complete, no replay prize will be awarded. When you win a replay, there will be no medals paid out, but you can start the next game without setting the number of bets again, so the number of bets that you no longer need to set in the next game (the regular bonus will not be replayed and will always be 3) This is substantially the same as paying out three medals corresponding to. Since “JAC” is arranged with an interval of 5 frames or less for all of the reels 3L, 3C, and 3R, when a replay is won in an internal lottery described later, the replay is always won.

  Hereinafter, the internal lottery will be described. The internal lottery is to determine whether or not the winning of each of the above combinations is permitted before the display result of the variable display device 2 is derived and displayed (actually, when the start lever 11 is operated). . In the internal lottery, a random number for internal lottery (an integer from 0 to 16383) is acquired from the random number generation circuit 115. Then, for each combination determined according to the gaming state, the acquired random number for internal lottery, the number of bets set by the player, and each combination determined according to the set value set by the setting switch 91 This is performed according to the number of judgment values. Winning in the internal lottery is exclusive.

  FIG. 5B is a diagram showing a winning combination table by gaming state. The winning combination table according to gaming state is stored in advance in the ROM 113 and is used to determine the winning combination determined in the internal lottery. The registered content of the winning combination table according to gaming state depends on the gaming state. It shows the role that has been determined. In the game state of each game, a combination that is a lottery target is referred to. Here, a plurality of winning combinations may be subject to lottery at the same time.

  When the gaming state is a regular bonus (including a case where the bonus is provided during a big bonus), watermelon, bell, and cherry are sequentially read out as a target for internal lottery. During normal gaming, regular bonus + watermelon, regular bonus, big bonus (1) + watermelon, big bonus (1), big bonus (2) + watermelon, big bonus (2), watermelon, bell, cherry, Replay (normal) is sequentially read out as a target combination of internal lottery. When the game state is RT, regular bonus + watermelon, regular bonus, big bonus (1) + watermelon, big bonus (1), big bonus (2) + watermelon, big bonus (2), watermelon, bell, cherry, Replay (RT) is sequentially read out as a target combination for internal lottery.

  In the internal lottery, the number of judgment values determined for the target part of the internal lottery is sequentially added to the random number for the internal lottery, and when the result of the addition overflows, it is determined that the target part is won. Is done. If the winning combination is determined, the winning flag of the combination is set in the RAM 112. The number of determination values is read in accordance with the storage address of the number of determination values registered in the role table stored in advance in the ROM 113. FIG. 5C is a diagram illustrating an example of the role-specific table. Watermelon, bell and cherry are subject to internal lottery in any gaming state, corresponding to the storage address of the number of judgment values corresponding to the regular bet number 1 with the regular bonus, and the bet number 3 in the normal gaming state and RT The storage address of the number of judgment values is registered. The number of determination values may be 256 or more, and cannot be stored for one word. Therefore, each determination value number is registered using a storage area for two words.

  The number of determination values of the combination to be a lottery target is registered corresponding to the number of bets (BET) set by the player in the game for each combination. This is because even if the winning combinations are the same, the winning probability in the regular bonus may be different from the winning probabilities in other gaming states. In addition, the number of determination values according to the number of bets of the combination to be a lottery object may be common regardless of the set value, and may be different depending on the set value. If the number of determination values is common regardless of the set value, a common flag is set (value is set to “1”).

  Regular Bonus + Watermelon, Big Bonus (1) + Watermelon, Big Bonus (2) + Watermelon are subject to internal lottery in the normal gaming state or RT, the decision corresponding to the normal gaming state and the number of bets in RT 3 The storage address for the number of values is registered. The value of the common flag for these roles is 1, and a storage address for a common number of determination values is registered regardless of the set value. The regular bonus, the big bonus (1), and the big bonus (2) are subject to internal lottery in the normal gaming state or RT, and the storage addresses of the number of judgment values corresponding to the number of bets 3 in the normal gaming state and RT Is registered. For these combinations, the value of the common flag is 0, and the storage address for the number of determination values is individually registered according to the set value.

  Watermelon, bell and cherry are subject to internal lottery in any gaming state, corresponding to the storage address of the number of judgment values corresponding to the regular bet number 1 with the regular bonus, and the bet number 3 in the normal gaming state and RT The storage address of the number of judgment values is registered. Among these small roles, the value of the common flag for the roles other than cherry is 1, and the storage address of the common number of judgment values is registered regardless of the set value regardless of whether the number of bets is 1 or 3. Yes. The common flag for cherry is 0, and the storage address of the number of determination values is individually registered according to the set value regardless of whether the number of bets is 1 or 3.

  The replay is subject to internal lottery in the normal gaming state or RT, but the storage address of the judgment value number is set to 3 bets in each gaming state as a separate lottery target in the normal gaming state and RT. Correspondingly registered. For both the replay in the normal gaming state and the replay in RT, the common flag is 1, and a common storage address for the number of determination values is registered regardless of the set value.

  FIG. 6 is a diagram illustrating a storage area for the number of determination values acquired based on the addresses registered in the role-specific table. The storage area for the number of determination values is provided in the RAM 112 for the development model and in the address area allocated to the ROM 113 for the mass production model.

  For example, the address ADD + 0 is an address that is referred to when the target part of the internal lottery is regular bonus + watermelon and the set value is 1-6. The address ADD + 14 is an address that is referred to when an internal lottery target role is a big bonus (1) + watermelon and a set value is 1-6. The address ADD + 28 is an address that is referred to when the internal lottery target role is the big bonus (2) + watermelon and the set value is 1-6.

  The address ADD + 2 is an address that is referred to when the target character of the internal lottery is a regular bonus and the set value is 1, and at this time, the value 11 stored here is acquired as the number of determination values. Addresses ADD + 4, ADD + 6, ADD + 8, ADD + 10, and ADD + 12 are addresses that are referred to when the target character of the internal lottery is a regular bonus and the set value is 2 to 6, respectively. Regarding the regular bonus, the number of judgment values is individually stored according to the set value, but since the same number of judgment values is stored, the winning probability of the regular bonus is the same at any set value. Yes. Since the regular bonus + watermelon has the same number of determination values as the setting values 1 to 6, the winning probability of the regular bonus is the same regardless of the setting value, even in the case of overlapping winning with the watermelon.

  The addresses ADD + 16, ADD + 18, ADD + 20, ADD + 22, ADD + 24, and ADD + 26 are addresses that are referred to when the internal lottery target role is the big bonus (1) and the set value is 1 to 6, respectively. Addresses ADD + 30, ADD + 32, ADD + 34, ADD + 36, ADD + 38, and ADD + 40 are addresses that are referred to when the internal lottery target is the big bonus (2) and the set value is 1 to 6, respectively. With regard to the big bonuses (1) and (2), the number of determination values is individually stored according to the set value, and a different number of determination values is stored, so that the big bonus (1), ( The winning probabilities in 2) will be different.

  The address ADD + 42 is an address that is referred to regardless of the set value when the number of bets is 3, that is, in the normal gaming state or when the target combination of the internal lottery is a watermelon in RT. The address ADD + 44 is an address that is referred to regardless of the set value when the bet number is 1, that is, in the regular bonus, when the target combination of the internal lottery is a watermelon. The number of determination values for watermelon is registered according to the number of bets, but since the same value is registered, the winning probability of watermelon is the same in any gaming state.

  The address ADD + 46 is an address that is referred to regardless of the set value when the number of bets is 3, that is, in the normal gaming state or when the target character of the internal lottery is a bell in RT. The address ADD + 48 is an address that is referred to regardless of the set value when the number of bets is 1, that is, in the regular bonus, when the target character of the internal lottery is a bell. Since the number of judgment values for the bell is different depending on the number of bets, the winning probability of the bell differs depending on whether the gaming state is a regular bonus or the normal gaming state or RT. It will be.

  Addresses ADD + 50, ADD + 52, ADD + 54, ADD + 56, ADD + 58, and ADD + 60 are referenced when the bet number is 3, that is, when the target lottery is cherry and the set value is 1 to 6 in the normal gaming state or RT Address. When the bet number is 3, the number of determination values is individually stored according to the set value, and different determination value numbers are stored, so that the winning probability of the cherry differs according to the set value. .

  Addresses ADD + 62, ADD + 64, ADD + 66, ADD + 68, ADD + 70, and ADD + 72 are addresses that are referenced when the bet number is 1, that is, when the target for internal lottery is cherry and the set value is 1 to 6 in the regular bonus. . The number of determination values for the cherries when the bet number is 1 is individually stored according to the set value, but since the same number of determination values is stored, the winning probability of cherries at any set value is It is the same. In addition, since the number of bets is 3 and the set value is 6, it is the same as the determination value of cherry. When the set value is 6, the winning probability of cherry is the same in any gaming state.

  The addresses ADD + 74 and ADD + 76 are addresses that are referred to regardless of the set value when the bet number is 3 in the normal replay and the bet number is 3 in the replay at the RT, regardless of the set value. , 2245 and 12552 are acquired as the number of determination values, respectively. In RT, the number of replay determination values is larger than in the normal gaming state, and the replay winning probability is higher than in the normal gaming state.

  In the normal gaming state, the medal payout rate is smaller than 1 (that is, the medal to be paid out for the small role won in the internal lottery with respect to the number of medals inserted for setting the bet number. Is smaller). In RT, the replay winning probability is higher and the medal payout rate is higher than in the normal gaming state, and is larger than 1 (that is, internal to the number of medals inserted for setting the bet number). The number of medals that will be paid out for the small role won in the lottery is larger). In the regular bonus and the big bonus, the medal payout rate is larger than that of the RT. The relation of the medal payout rate according to the gaming state described here is the same when the set value is any one of 1-6.

  Next, acquisition of random numbers for internal lottery will be described in detail with reference to FIG. The random numbers for the internal lottery are acquired by extracting random numbers from the random number generation circuit 115 by the hardware random number function and processing them by software by the CPU 111. When acquiring a random number for internal lottery, a random number for determining notification for determining whether or not to turn on the bonus notification lamp 66 is also acquired. The least significant bit of the random number generated by the random number generation circuit 115 is referred to as the 0th bit, and the most significant bit is referred to as the 15th bit.

  FIG. 7A is a block diagram showing the configuration of the random number generation circuit 115 in detail. As shown in the figure, the random number generation circuit 115 includes a pulse generation circuit 115a, a lower counter 115b, and an upper counter 115c. The lower counter 115b and the upper counter 115c are both 8-bit (1 byte) counters, the lower counter 115b is the 0th bit to the 7th bit, and the upper counter 115c is a total of 16 bits from the 8th bit to the 15th bit. The data signal is output.

  The pulse generation circuit 115a outputs a pulse signal at a frequency that is higher than the frequency of the operation clock of the CPU 111 and is not an integral multiple thereof (preferably relatively prime). The pulse signal output from the pulse generation circuit 115a is clocked into the lower counter 115b.

  The lower counter 115b alternately inverts the 0th bit data signal between the H level and the L level every time a pulse signal is input from the pulse generation circuit 115a. Assuming that positive logic is applied, a logical value of H level corresponds to 1 and a logical value of L level corresponds to 0. In the case of negative logic, a logic value of 1 may be read as L level, and a logic value of 0 may be read as H level. When the level of the 0th bit data signal is inverted from H level to L level, that is, whenever the logic value of the 0th bit data signal changes from 1 to 0, the level of the 1st bit data signal is changed to H level. Inverted alternately with L level.

  Similarly, when the level of the (m−1) th bit data signal is inverted from the H level to the L level, that is, whenever the logic value of the (m−1) th bit data signal changes from 1 to 0, the mth bit data The signal level is alternately inverted between the H level and the L level. Further, when the level of the seventh bit data signal is inverted from the H level to the L level, that is, whenever the logic value of the seventh bit data signal changes from 1 to 0, a carry signal is output. The carry signal output from the lower counter 115b is clocked into the upper counter 115c.

  The upper counter 115c alternately inverts the eighth bit data signal between the H level and the L level every time a carry signal is input from the lower counter 115b. Each time the level of the 9th bit data signal is inverted from H level to L level, the level of the 9th bit data signal is alternately inverted between H level and L level. Similarly, every time the level of the m−1th bit data signal is inverted from the H level to the L level, the level of the mth bit data signal is alternately inverted between the H level and the L level.

  The logic value of the 16-bit data signal in which the data signal of the lower counter 115b is the lower 8 bits and the data signal of the upper counter 115c is the upper 8 bits is 0 (0000h) every time the pulse generation circuit 115a outputs the pulse signal. ) → 1 (0001h) → 2 (0002h) →... → 65535 (FFFFh) The values are updated so as to be continuous every update, and the maximum value 65535 (FFFFh) is next to the initial value 0 (0000h). The value circulates and is output from the random number generation circuit 115.

  The sampling circuit 116 includes a latch circuit. Based on a sampling command from the CPU 111 (when the start lever 11 is operated), the sampling circuit 116 latches and latches the 16-bit data signal output from the random number generation circuit 115 at that time. Output the data signal. The CPU 111 extracts numerical data corresponding to the data signal input from the sampling circuit 116 via the I / O port 114 as a random number generated by the random number generation circuit 115. Hereinafter, the data signal output from the random number generation circuit 115 will be described as a random number corresponding to the logical value.

  FIG. 7B is an explanatory diagram until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. The random number extracted from the random number generation circuit 115 is stored in a 16-bit general-purpose register 111GR included in the CPU 111.

  When the random number extracted from the random number generation circuit 115 is stored in the general-purpose register 111GR, the CPU 111 uses the other general-purpose register or the work area of the RAM 112 to lower byte of the general-purpose register 111GR (value extracted from the lower counter 115b). And the value of the upper byte (the value extracted from the upper counter 115c) are exchanged.

  Next, the CPU 111 performs an AND operation on the value of the random number obtained by exchanging the upper byte and the lower byte for the extracted random number with 8080h. Since the processing word of the CPU 111 is 1 byte, the logical product operation is actually performed sequentially on the upper byte and the lower byte. The 15th bit and the 7th bit are always 1 by this logical product operation. Further, the CPU 111 shifts the upper 1 byte (8th bit to 15th bit) to the lower bit by bit, and inserts 1 into the empty 15th bit.

  The CPU 111 acquires the value stored in the general-purpose register 111GR at this time as a random number for internal lottery, stores it in a predetermined area of the RAM 112, and sequentially adds the number of determination values of each combination to this. It becomes. Since the 15th and 14th bits of the random number for internal lottery are always 1, the random number for internal lottery is a random number having a size of 14 bits (16384), which is substantially 0 to 16383. It takes a value.

  Note that interrupts to the CPU 111 are prohibited from the extraction of random numbers from the random number generation circuit 115 to the end of processing. This is to prevent the contents of the general-purpose register 111GR from being rewritten in the interrupt processing routine when an interrupt occurs to the CPU 111.

  Next, stop control of the reels 3L, 3C, 3R will be described. The CPU 111 refers to the table index and table creation data stored in the ROM 113 when the reel starts rotating and when the reel is stopped and the reel that is still rotating still remains. Create a stop control table for each reel. When any of the stop buttons 12L, 12C, and 12R corresponding to the rotating reel is effectively detected, the stop control table of the corresponding reel is referred to, and the referred stop control table is drawn. Based on the number of frames, control is performed to stop the rotation of the reels 3L, 3C, 3R corresponding to the operated stop buttons 12L, 12C, 12R.

  FIG. 8 is a diagram showing a table index stored in the ROM 113. As shown in the figure, the table index stores the top address of the area where the data for table creation is stored for each internal winning situation.

  Even if the internal winning situation is different, if the same control is applied, the same address is stored as the start address of the area where the data for table creation is stored. In this case, the stop control table is created with reference to the same table creation data. Here, the table creation data is made up of drawn-in frame number data indicating the number of drawn-in frames corresponding to the stop operation position, and the address of the drawn-in frame number data to be referred to according to the reel stop status.

  The number-of-drawing frame data referred in accordance with the reel stop status indicates whether all the reels 3L, 3C, 3R are rotating, only the left reel 3L is stopped, only the middle reel 3C is stopped, or the right reel Depending on whether only 3R is stopped, left and middle reels 3L and 3C are stopped, left and right reels 3L and 3R are stopped, and middle and right reels 3C and 3R are stopped. In addition, in a situation where any of the reels 3L, 3C, 3R is stopped, it may differ depending on the stop position of the stopped reel.

  In the table creation data, the address of the drawing frame number data to be referred to is registered for each reel being rotated for each situation. The address of the number of frames to be drawn that should be referred to according to each situation can be specified based on the top address of the table creation data. From this specified address, the number of frames to be drawn that are necessary for each situation can be obtained. It can be specified. Even if the reel stop status and the stop position of the stopped reel are different, the same address is registered as the address of the number of frames to be drawn when the same number of frames to be drawn is applied. In such a case, the same data for the number of drawn frames is referred to.

  Further, the number of drawn frames data is data that can specify the number of drawn frames for each timing when the stop operation is performed. For the reel motors 3ML, 3MC, and 3MR, stepping motors that make one round with a cycle of 168 steps (0 to 167) are used. That is, when the reel motors 3ML, 3MC, and 3MR are driven in 168 steps, the reels 3L, 3C, and 3R make one round. 21 areas (frames) divided every 8 steps (the number of steps in which one symbol moves) are defined for one reel. These areas are areas 1 to 21 from the reel reference position. A number is assigned (see FIG. 9).

  On the other hand, the number of symbols arranged on one reel is 21, and symbol numbers 1 to 21 from the reel reference position are assigned to symbols on each reel, so symbols 1 to 21 are assigned to each reel. , Area numbers 1 to 21 are assigned in order. The number of drawn frames by area number is compressed and stored according to a predetermined rule in the number of drawn frames data so that the number of drawn frames by area number can be acquired by expanding the number of drawn frames data. It has become.

  FIG. 9 is a diagram illustrating an example of the stop control table. As described above, the stop control table is created with reference to the table index and the table creation data. In the stop control table, as shown in FIG. 9, the area corresponding to each area number is located at the stop reference position (in this embodiment, the lower symbol area in the transparent window 3). The number of frames to be drawn when the operation of the stop buttons 12L, 12C, 12R is detected at the timing (the timing at which the number of steps from the reel reference position is included in the range of the number of steps of each area number) is set.

  Next, the procedure for creating the stop control table will be described. First, at the start of reel rotation, the top address of the table creation data corresponding to the internal winning situation in the game is acquired. Then, the table creation data is specified based on the acquired head address, and the address of the drawing frame number data of each reel corresponding to the state in which all the reels 3L, 3C, 3R are rotating is acquired from the specified table creation data. Then, the drawing frame number data of each reel stored at the acquired address is developed to create a stop control table for all the reels 3L, 3C, 3R.

  Also, when any one of the reels 3L, 3C, 3R is stopped or when any two are stopped, a table is created according to the top address acquired at the start of reel rotation, that is, the internal winning situation in the game. The table creation data is identified based on the start address of the data, and the address of the number of frames to be drawn in the unreacted reel corresponding to the stopped reel and the area number of the stop position of the reel is obtained from the identified table creation data. Then, the drawing frame number data of each reel stored at the acquired address is expanded to create a stop control table for the unstopped reels.

  Next, when the CPU 111 effectively detects any one of the stop buttons 12L, 12C, and 12R corresponding to the rotating reel, the control when the display result is derived to the corresponding reel will be described.

  When any of the stop buttons 12L, 12C, and 12R corresponding to the rotating reel is detected effectively, the area number of the stop operation position is based on the number of steps from the reel reference position when the stop operation is detected. And the number of drawn frames corresponding to the area number of the specified stop operation position is acquired by referring to the stop control table of the reel where the stop operation is detected. Then, control is performed to rotate and stop the reel by the number of acquired frames. Specifically, from the number of steps from the reel reference position at the time when the stop operation is detected, the number of steps from the acquired number of drawn frames until the stop is calculated and the reel is rotated and stopped by the calculated number of steps. Take control. As a result, an area (stop point in the figure) corresponding to the area number corresponding to the stop position ahead of the number of frames to be drawn in from the area (stop operation point in the figure) corresponding to the area number of the stop operation position where the stop operation is detected. The vehicle stops at the stop reference position (in this embodiment, the lower symbol area).

  Further, the table index stores only one address as the start address of the table creation data storage area corresponding to one internal winning situation, and one table creation data contains one reel. Only one address is stored as the address of the storage area for the number of drawn frame data corresponding to the stop status (and the stop position of the stopped reel). In other words, the table creation data corresponding to one internal winning situation and the number-of-drawing frame data corresponding to the reel stop situation (and the stop position of the stopped reel) are uniquely determined. The created stop control table is also unique with respect to one internal winning status and the reel stop status (and the stop position of the stopped reel). Therefore, when all of the internal winning status and the reel stop status (and the stop position of the stopped reel) are the same, the reel stop control is performed based on the same stop control table, that is, the same control pattern. Will be performed.

  Also, a value of 0 to 4 is determined as the number of drawn frames, and it is possible to stop the reel by drawing a maximum of four symbols after detecting a stop operation. In other words, the stop position of the symbol can be designated from a range of a maximum of 5 frames including the stop operation position where the stop operation is detected. In addition, since it is necessary to move one frame to move the reel for one symbol, it is possible to stop the reel by pulling in a maximum of four symbols after detecting the stop operation. The symbol stop position can be designated from a range of up to five symbols including the operation position.

  In addition, in the table index, the number of drawn-in frames is drawn so that the winning combination is drawn to the maximum in the range of 4 frames and no winning combination is arranged, corresponding to the case where any combination is won. A predetermined table creation data address is stored. Corresponding to the case of a loss, a table creation data address is stored in which the number of frames to be drawn is determined so that none of the roles can be obtained. Therefore, if any winning combination is won, there will be a stop control table in which the winning combination is drawn to the maximum in the range of 4 frames and the number of drawing frames to be drawn is set so that the winning combination is not aligned. It is created and reel stop control is performed. On the other hand, in the case of losing, a stop control table in which the number of frames to be drawn that do not have any combination is created, and reel stop control is performed. As a result, when the stop operation is performed, if the symbols of the winning combination can be stopped on the winning line in the drawing range of up to 4 frames, the control is performed to align them and stop. The symbol of the winning combination will be controlled to be stopped in a drawing range of a maximum of 4 frames.

  In the table index, when a special combination and a small combination are won at the same time, or when a special combination is won with the special combination carried over from before the previous game (Big Bonus (1) + Watermelon, Big Bonus ( In response to 1) + Bell, etc., the number of draws is determined so that the winning special role is drawn to the maximum in the range of 4 frames, and the winning special role is drawn in the range of up to 4 frames. For the non-stop operation position, the address of the table creation data in which the number of drawn frames is determined so that the selected winning combination is drawn to the maximum within the range of four frames is stored, and reel stop control is performed. As a result, when the stop operation is performed, if the symbols of the special roles that have been elected in the drawing range of up to 4 frames can be stopped on the winning line, the control is performed to stop them together. If you can't draw a special role that you have won in the drawing range of up to 4 frames on the winning line, you can align the symbols of the small role that has been won in the drawing range of up to 4 frames on the winning line. If they can be stopped, control is performed to stop them together, and the symbol of the winning combination is controlled to be stopped in the drawing range of 4 frames. That is, in such a case, priority is given to the control for aligning the special combination on the winning line over the small combination, and the small combination can be won only when the special combination cannot be drawn.

  In addition, the table index includes a range of 4 replays corresponding to the case where a replay player is elected with a special role being carried over from before the previous game (such as big bonus (1) + replay). The address of the table creation data in which the number of frames to be drawn is determined so as to be pulled in to the maximum is stored, and reel stop control is performed. As a result, when a stop operation is performed, control is performed so that the symbols of the re-gamer are aligned and stopped on the winning line within a drawing range of up to four frames. “JAC” which is a symbol constituting the re-gamer is arranged at intervals of 5 frames or less for all of the reels 3L, 3C and 3R, and is always stopped at an arbitrary position within the drawing range of 4 frames. be able to. When a special game is carried over from before the previous game and a re-game player is elected, the re-game game will always be awarded regardless of the operation timing of the stop buttons 12L, 12C, 12R by the player. It will be. That is, in such a case, the control for aligning the re-games on the winning line has priority over the special game, and the re-games will always win.

  On the game control board 101 side, the internal lottery is performed as described above, and the rotation of the reels 3L, 3C, 3R is stopped according to the result and the operation timing of the stop buttons 12L, 12C, 12R, and a prize is generated. It will be a thing. As a result of winning a prize, a medal is paid out or a game state is transferred as a payout. In this way, depending on the progress of the game on the game control board 101 side, an original effect is performed on the effect control board 102 side. Is called. In order to perform such an effect, the CPU 121 of the effect control board 102 must be able to recognize the progress of the game on the game control board 101 side. Is transmitted from the game control board 101 to the effect control board 102.

  The commands transmitted from the game control board 101 to the effect control board 102 include at least a winning status notification command, a reel rotation command, a reel stop command, a winning information command, and a gaming state command. The commands transmitted from the game control board 101 to the effect control board 102 include other commands, but since they are not directly related to the present invention, a detailed description thereof is omitted.

  The winning status notification command indicates the setting status of the winning flag in the RAM 112, and is transmitted when the start lever 11 is operated and an internal lottery is performed. The reel rotation command indicates the timing at which the reels 3L, 3C, and 3R start to rotate, and is transmitted when the rotation of the reels 3L, 3C, and 3R is actually started. The reel stop command indicates the number of symbols stopped at the middle and the other of the reels 3L, 3C, and 3R, and is transmitted when the reels 3L, 3C, and 3R are stopped.

  The winning information command indicates a type of winning (including no winning) generated according to the display result of the variable display device 2, and when the display result is derived to the variable display device 2 and the winning determination is performed. Sent. The gaming state command indicates a gaming state applied in the next game, and is transmitted at the end of one game. When the gaming state command indicates that the gaming state is at RT, the number of remaining RT games is at least 4 games or more, and can be distinguished from three games, two games, and one game. The fact that the number of remaining RT games indicated by the game state command is 4 games or more means that it is always a long RT.

  The CPU 121 of the effect control board 102 performs various effects based on the commands sent from the CPU 111 of the game control board 101 as described above. As an effect performed by the control of the CPU 121, an effect performed particularly on the liquid crystal display 4 is an SRT performed when there is a possibility that the chance eye is derived when there are 4 or more long RT remaining games. Possibility announcement, chance presentation performed when chance chance is not derived in game with SRT possibility announcement, and multiple games when the number of remaining RT games including short RT is 3 games or less There is a continuous production that is executed.

  The SRT possibility notification is made when there is a possibility that chances are derived in a game in which the number of remaining RT games is 4 or more (in this case, always long RT), that is, regular bonus, big bonus (1) or Performed when winning big bonus (2) and / or watermelon. The SRT possibility notification effect is not performed in a manner that directly indicates that there is a possibility that a chance will be derived, but a regular bonus, a big bonus (1) or a big bonus when the number of remaining RT games is four or more. This is done by displaying on the liquid crystal display 4 a predetermined image that is never displayed except when the bonus (2) and / or watermelon is won.

  Chance production is performed when no chance is derived in the game for which the SRT possibility notification has been made, but from the viewpoint of winning, the chance is lost, so even if the winning information command is referenced, the display of the loss is displayed. If the result is derived, the CPU 121 of the effect control board 102 cannot recognize whether it is a chance. The display mode derived to the variable display device 2 (in particular, whether all the reels 3L, 3C, 3R are stopped and the chance eyes are derived) is determined based on the reel rotation command and the reel stop command. The

  The RAM 122 is provided with a stop symbol table for determining the display mode of the variable display device 2 based on the reel stop command. However, since the reel stop command includes only the type of the stopped reel and the number of the symbol stopped in the middle as information, it is impossible to determine what symbol is stopped by this alone. Tables indicating all symbols arranged in 3C, 3R are stored in advance, and symbols stopped on the reels 3L, 3C, 3R are registered in the stop symbol table with reference to this table.

  In addition, the continuous effect is started in a game in which the number of remaining RT games is 3, and is terminated after a period of three games is continued until a game in which the number of remaining RT games is 1. Continuous production starts even in games where 97 RT games have been digested in the long RT and the remaining RT game count is 3, but in games controlled to short RT by derivation of chances in the previous game, be sure to It will be started. The number of remaining RT games can be determined by a game state command transmitted from the game control board 101.

  Even after winning 97-99 games in the long RT, the regular bonus, big bonus (1) or big bonus (2) may not be won. Therefore, the continuous performance is performed both when the regular bonus, the big bonus (1) or the big bonus (2) are won (including carryover) or not.

  There is a high possibility that the continuous performance will be performed when the regular bonus, the big bonus (1) or the big bonus (2) is won, but the regular bonus, the big bonus (1) and the big bonus (2) Since it may be performed when neither is won, it has a character as a bonus notice. If the regular bonus, the big bonus (1), or the big bonus (2) is won at the end of the continuous performance, a bonus notification that informs the player that these roles are won will be given. Done.

  Further, when a regular bonus, a big bonus (1) or a big bonus (2) is won, a bonus winning effect is performed. Bonus winning effects may differ depending on whether you win the regular bonus, the big bonus (1) or the big bonus (2), and the regular bonus will be awarded according to the gaming state to be controlled after that. The contents may differ depending on whether the big bonus (1) or the big bonus (2) is won.

  The RAM 122 has areas for setting an SRT flag indicating that an SRT possibility notification is being performed, a continuous exercise flag indicating that a continuous performance is being performed, and a bonus notification flag indicating that a bonus notification has already been performed. Is provided. Furthermore, in addition to the stopped symbol table for storing the type of symbols stopped on the reels 3L, 3C, 3R, an area for storing the winning status indicated by the winning status notification command, and an area for storing the gaming status indicated by the gaming status command Is provided in the RAM 122.

  Hereinafter, processing in the slot machine 1 according to this embodiment will be described. In the slot machine 1, the game is progressed by repeatedly performing the game process one game at a time. For this purpose, the game must be in a state where the game can be progressed. In order to be able to advance the game, the setting value of the normal range is stored in the setting value work 112-4 with the control unit 110 including the CPU 111 activated, and the data stored in the RAM 112 is stored in the data stored in the RAM 112. The condition is that there is no abnormality.

  FIG. 10 is a flowchart showing a startup process executed by the CPU 111 of the game control board 101. This activation process is a process performed when a reset signal is input from the reset circuit of the game control board 101 and the control unit 110 is activated. Since the reset signal is a signal that is output when the power is turned on and when the operation of the control unit 110 is stagnant, the activation process is accompanied by the activation of the control unit 110 that accompanies power-on and a malfunction of the control unit 110. This process is performed when restarting.

  In the startup process, first, the built-in device, peripheral IC, stack pointer, and the like are initialized (step S101), and access to the RAM 112 is permitted (step S102). Then, it is determined whether or not the setting key switch 92 is in an ON state (step S103). If the setting key switch 92 is not ON, the RAM parity is calculated based on all the data stored in the RAM 112 except the parity storage area 112-7 (step S104).

  Next, the RAM parity calculated here is compared with the RAM parity stored in the parity storage area 112-7, that is, the RAM parity calculated and stored at the previous power-off (step S105). Whether or not the data stored in the RAM is normal (step S106). In this embodiment, whether or not the RAM 112 is normal based on the RAM parity is determined only in the startup process.

  If the RAM parities do not match in step S106, the data stored in the RAM 112 is not normal, and the routine proceeds to the RAM abnormality error processing shown in FIG. If the RAM parities match, the data stored in the RAM 112 is normal, so the register stored in the stack area 112-6 is restored (step S107), and the interrupt prohibition is canceled (step S107). S108), the process returns to the state before the power is turned off.

If the setting key switch 92 is ON in step S103, all the data stored in the RAM 112 is initialized except for the area in use in the stack area 112-6 (other than the setting value work 112-4). Is rewritten to 1 and the set value work 112-4 is rewritten to 1 ) (step S109), the prohibition of interruption is canceled (step S110), and the process proceeds to the setting change process shown in FIG. 11 (step S111). Then, after the setting change process is completed, the game can be progressed and the process proceeds to the game control process.

  FIG. 11 is a flowchart showing in detail the setting change process executed by the CPU 111 in step S111. In the setting change process, first, a setting changing flag indicating that the setting changing mode is being set is set in a predetermined area of the RAM 112 (step S201), and the setting value (setting change) stored in the setting value work 112-4 is set. Before shifting to the processing, the value of the set value work 112-4 has been rewritten to 1, so it is 1 here) (step S202).

  Thereafter, the operation waits for detection of the operation of the setting switch 91 and the start switch 41 (steps S203 and S204). When the operation of the setting switch 91 is detected in step S203, 1 is added to the setting value read in step S202 (step S205), and whether or not the setting value after the addition is 7, that is, whether the normal range has been exceeded. It is determined whether or not (step S206). If the set value after addition is not 7, the process returns to the state of waiting for detection of the operation of the setting switch 91 and the start switch 41 in steps S203 and S204. If the set value after addition is 7, the set value is corrected to 1 (step S207), and the process returns to the state of waiting for detection of the operation of the setting switch 91 and the start switch 41 in steps S203 and S204.

  When the operation of the start switch 41 is detected in step S204, the changed set value selected at that time is stored in the set value work 112-4 and the set value is confirmed (step S208). Thereafter, the process waits until the setting key switch 92 is turned off (step S209). If it is determined in step S209 that the setting key switch 92 has been turned off, the setting changing flag set in step S201 is cleared (step S210). Then, when returning to the flowchart of FIG. 10, the game can be progressed and the game control process is started.

  FIG. 12 is a flowchart showing in detail the RAM abnormality error process executed by the CPU 111 of the game control board 101. In the RAM abnormality error process, the payout display 51 is controlled to display the RAM abnormality error code on the payout display unit 21 (step S301), and then the process proceeds to a loop process in which no process is performed.

  As described above, in the startup process, when the setting key switch 92 is not in the ON state, the data stored in the RAM 112 is compared by comparing the RAM parity calculated at the time of power-off with the RAM parity calculated at the time of startup. It is determined whether or not it is normal, and the routine proceeds to RAM abnormality error processing. In the RAM abnormality error process, since the RAM abnormality error code is displayed on the payout display unit 21, the process proceeds to a loop process in which no process is performed, so that the progress of the game is disabled.

  If the RAM parity does not match, the interrupt is not permitted. Therefore, once the process proceeds to the RAM abnormality error process, the setting key switch 92 is activated in the ON state until the interrupt prohibition is canceled. Even if the power is cut off, no power interruption processing is performed. In other words, since no new RAM parity is calculated and stored in the power interruption process, the RAM parity is always set except when the setting key switch 92 is activated even when the control unit 110 is activated. Since they do not match, the control unit 110 cannot be activated to start (resume) the game.

  Once the RAM abnormal error state is entered, the setting key switch 92 is turned on, the setting key switch 92 is turned on, setting change processing is performed, and a new set value is selected and set by operating the setting switch 91 until the game is played. It becomes impossible to progress. In other words, in the state that has shifted to the RAM abnormal error state, the state in which the game cannot be progressed is released on the condition that a new set value is selected and set by operating the setting switch 91, and the game is started (resumed). It becomes possible to make it. In the error state other than the RAM abnormal error, there is no problem of the RAM parity mismatch, so that the state where the game cannot be progressed is canceled only by the operation of the first reset switch 48 or the second reset switch 93, and the game is resumed. Can be made.

  As described above, when the game can be progressed, the game processing is repeated one by one in the slot machine 1. Hereinafter, each game in the slot machine 1 will be described. The “game” in the slot machine 1 is, in a narrow sense, from the operation of the start lever 11 to the stop of the reels 3L, 3C, 3R. Since the bet number before the operation is set, the medals are paid out and the game state is shifted after the reels 3L, 3C, and 3R are stopped, these accompanying processes are also included in the “game” in a broad sense. . It should be noted that the transmission of commands from the game control board 101 to the effect control board 102 will be described only for those necessary for the description of the present invention, and the description of the transmission of other commands will be omitted.

  FIG. 13 is a flowchart showing a game control process performed by the CPU 111 of the game control board 101 for each game. This process is also executed after the power is turned on and a predetermined boot process is performed, or immediately after the setting is changed by operating the setting switch 91. When the process of one game is started, an initial process including a process of clearing a predetermined area of the RAM 112 is first performed (step S401).

  Next, the number of bets is set by operating one BET button 14 or MAXBET button 15 or by inserting medals from the medal insertion slot 13, and operating the start lever 11 to substantially change the game. BET processing for instructing start is performed (step S402). Here, when the gaming state is a regular bonus (including that provided during the big bonus), if the bet number is set to 1 (the bet number larger than this is not set), the start lever 11 is activated. Become. In other game states, the start lever 11 becomes effective after 3 is set as the bet number. Further, if the player has won a replay in the previous game, the same bet number (3 in this embodiment) as the previous game is automatically set by the replay game flag (the replay game flag is erased at this stage). The start lever 11 becomes effective as it is.

  When the number of bets is set by the BET process and the start lever 11 is operated, a random number for internal lottery is extracted, and winning to each combination determined according to the gaming state is allowed based on the extracted random number value A lottery process for determining whether or not to perform is performed (step S403). In the lottery process, a winning status notification command indicating the setting status of the winning flag in the RAM 112 is transmitted to the effect control board 102. Details of the lottery process will be described later.

  When the lottery process is completed, a reel rotation process is performed (step S404). In the reel rotation process, the reel motor is operated on the condition that a predetermined time (for example, 4.1 seconds) has elapsed from the start of rotation of the reels 3L, 3C, and 3R in the previous game. 3ML, 3MC, and 3MR are driven to start rotation of all the left, middle, and right reels 3L, 3C, and 3R. When predetermined conditions (detection of the reference position by the reel sensors 3SL, 3SC, 3SR after the rotation speed reaches a certain speed) from the start of rotation of the reels 3L, 3C, 3R are satisfied, the stop buttons 12L, 12C, 12R Is enabled. Thereafter, when the stop buttons 12L, 12C, and 12R are operated by the player, the driving of the reel motors 3ML, 3MC, and 3MR is stopped according to the setting state of the winning flag, and the rotation of the reels 3L, 3C, and 3R is stopped. . When the rotation of the reels 3L, 3C, 3R is started and stopped, a reel rotation command and a reel stop command are transmitted to the effect control board 102, respectively. Details of the reel rotation process will be described later.

  When the driving of each of the reels 3L, 3C, 3R is stopped, in the display mode at the time of stopping, is any of the above-mentioned role symbols derived and displayed on the winning line according to the bet number set in the BET process in step S402? A winning determination process for determining whether or not is performed (step S405). If it is determined in this winning determination process that a winning combination has been won, various processes corresponding to the winnings generated on the game control board 101 are performed. Here, a winning information command indicating a winning determination result is sent to the effect control board 102. Details of the winning determination process will be described later.

  When the winning determination process ends, a payout process is performed (step S406). In the payout process, the credit is increased by the number of payouts set in the winning determination process. However, when the number of credits accumulated as data reaches 50, the hopper motor 82 is driven to pay out an excess number of medals from the medal payout slot 71. In addition, various processes that are not related to winning (for example, a process related to the end control of the big bonus and the deletion of the winning flag without carryover) are also performed. At the end of the payout process, that is, at the end of one game, a game state command indicating the game state of the next game is sent to the effect control board 102. Details of the payout process will be described later. Then, the process for one game ends, and the process for the next one game starts.

  Next, the lottery process in step S403 will be described in detail. FIG. 14 is a flowchart showing in detail the lottery process executed by the CPU 111 in step S403. In the lottery process, it is determined whether or not the gaming state is the big bonus depending on whether or not the big bonus flag is set in the RAM 112 (step S501). If the gaming state is not the big bonus, the process proceeds to step S504 as it is.

  If the gaming state is in the big bonus, it is determined whether the gaming state is in the regular bonus depending on whether the regular bonus flag is set in the RAM 112 (step S502). If the game state is not in the regular bonus, it is the first game of the big bonus, or the game is a game when the regular bonus for one set in the big bonus has ended and the big bonus has not ended yet. The regular bonus medium flag is set to the game state, and the gaming state is controlled to the regular bonus (step S503). Then, the process proceeds to step S504. If the gaming state is in the regular bonus, the process proceeds to step S504 as it is.

  In step S504, the bet number set in the current game is read. Next, it is determined whether or not the gaming state is a regular bonus (including a case where the bonus is provided during the big bonus) based on whether or not the regular bonus flag is set in the RAM 112 (step S505). If there is a regular bonus, it is determined whether or not the read bet number is 1 (step S506). If not in the regular bonus, it is determined whether or not the read bet number is 3 (step S507). When the bet number read at step S506 is not 1, or when the bet number read at step S507 is not 3, a RAM error occurs, and the RAM error process shown in FIG. 12 is performed. When the bet number read in step S506 is 1, or when the bet number read in step S507 is 3, the process proceeds to step S508.

  In step S508, the setting value stored in the setting value work 112-4 of the RAM 112 is read. Here, it is determined whether or not the read set value is in the range of 1 to 6 which is a value that should be taken (step S509). If the read set value is not in the range of 1 to 6, a RAM abnormality error occurs and the RAM abnormality error process shown in FIG. 12 is performed.

  If the read set value is in the range of 1 to 6, random number acquisition processing is performed, and a sampling command is output to cause the sampling circuit 116 to extract the random number generated by the random number generation circuit 115. The random number for lottery is processed into a random number storage area in the RAM 112 and stored in the random number storage area (step S510). Details of the random number acquisition process will be described later.

  Next, in correspondence with the current gaming state, the lottery target roles registered in the winning state-specific winning combination table of FIG. 5B are sequentially read (step S511). Next, the common flag setting status registered in the role-specific table of FIG. 5C for the read lottery target role is acquired (step S512). As a result, it is determined whether or not the common flag is set (step S513).

  If the common flag is set, the number of determination values stored in the address registered in the role-specific table of FIG. 5C corresponding to the read number of bets for the lottery object to be read is acquired ( Step S514). Then, the process proceeds to step S516. If the common flag is not set, the setting value set in the RAM 112 is read out and stored in the address registered in the combination table corresponding to the number of bets read and the setting value for the lottery target combination. The number of determination values is acquired (step S515). Then, the process proceeds to step S516.

  In step S516, the number of determination values acquired in step S514 or S515 is added to the internal lottery random value stored in the determination area of the RAM 112, and the result of the addition is used as a new random number for internal lottery. Here, it is determined whether or not an overflow has occurred when the number of determination values is added to the value of the random number for internal lottery (step S517).

  If no overflow has occurred, it is determined whether or not there is a combination that has not yet been processed among the lottery targets in the gaming state (step S518). If there is something that has not yet been processed, the process returns to the processing of step S511, and the processing is continued with the next lottery target registered in the winning combination table by gaming state as the processing target. If there is nothing not to be processed, the process proceeds to step S526.

  When an overflow occurs, it is determined whether or not the lottery target combination read in the immediately preceding step S511 is any of regular bonus + watermelon, big bonus (1) + watermelon or big bonus (2) + watermelon ( Step S519). If it is either regular bonus + watermelon, big bonus (1) + watermelon or big bonus (2) + watermelon, at least the game state in this game is a regular bonus (if it was offered during the big bonus Not included).

  Here, it is determined whether the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is set in the RAM 112 (step S520). If none of the regular bonus winning flag, big bonus (1) winning flag and big bonus (2) winning flag is set, the regular bonus winning flag, big bonus (1) winning flag or The big bonus (2) winning flag is set in the RAM 112, and the watermelon winning flag is set in the RAM 112 (step S521). Then, the process proceeds to step S526.

  If the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is already set in the RAM 112 in step S520, only the watermelon winning flag is set in the RAM 112 (step S522). Then, the process proceeds to step S526.

  In step S519, if the lottery target is neither regular bonus + watermelon, big bonus (1) + watermelon or big bonus (2) + watermelon, the lottery target is regular bonus, big bonus (1) or big It is determined whether or not the bonus is any of (2) (step S523). If the lottery target is any of the regular bonus, the big bonus (1), and the big bonus (2), the process proceeds to step S525. When the regular bonus, the big bonus (1), or the big bonus (2) is selected, the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is set in the RAM 112. It is determined whether or not (step S524).

  If any of the regular bonus winning flag, the big bonus (1) winning flag, and the big bonus (2) winning flag is set, the process directly proceeds to step S526. If none of the regular bonus winning flag, the big bonus (1) winning flag, and the big bonus (2) winning flag is set, the winning flag of the lottery subject is set in the RAM 112. Here, the lottery is not a regular bonus, a big bonus (1), or a big bonus (2), and is already a regular bonus winning flag, a big bonus (1) winning flag or a big bonus (2) winning flag. If it is set, the winning flag of the current lottery target role is set over the already set regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag (step S525). ). Then, the process proceeds to step S526.

  In step S526, a winning status notification command is generated according to the setting status of the winning flag in the RAM 112, and is transmitted to the effect control board 102. Then, the lottery process is terminated, and the process returns to the flowchart of FIG.

  Next, the random number acquisition process in step S510 will be described in detail. FIG. 15 is a flowchart showing in detail the random number acquisition process executed by the CPU 111 in step S510. In the random number acquisition process, first, an interrupt to the CPU 111 is prohibited (step S601). Next, a sampling command is output to the sampling circuit 116, the random number generated by the random number generation circuit 115 is latched, and the value of the latched random number is input from the I / O port 114 and extracted. The random number value extracted from the random number generation circuit 115 is stored in the general-purpose register 111GR (step S602).

  Next, the lower byte value and upper byte value of the random number stored in the general-purpose register 111GR are exchanged with each other using the work area of the RAM 112 (step S603). Next, the value of the random number stored in the general-purpose register 111GR is ANDed with 8080h (step S604). Further, the upper byte (15th to 8th bits) is shifted downward by 1 bit, and 1 is inserted into the empty 15th bit. At this time, the value stored in the general-purpose register 111GR is acquired as a random number for internal lottery and stored in a predetermined area of the RAM 112 (step S605). Then, after permitting the interrupt prohibited in step S601 (step S606), the random number acquisition process is terminated, and the process returns to the flowchart of FIG.

  Next, the reel rotation process in step S404 will be described in detail. FIG. 16 is a flowchart showing in detail the reel rotation process executed by the CPU 111 in step S404. In the reel rotation process, first, it is determined whether or not a wait time (for example, about 4.1 seconds) has elapsed since the reel rotation start time of the previous game (step S701), and if the wait time has not elapsed, Wait until the wait time has elapsed. If the wait time has elapsed, the timing of the wait time is newly started (step S702).

  Next, the work initialization code at the time of starting the rotation of the reel motor is set in the register, and the rotation of the reel is started (step S703). Here, a reel rotation command indicating that the reels 3L, 3C, and 3R have started rotating is generated and transmitted to the effect control board 102 (step S704). Then, with reference to the table index, the table creation data is identified, and based on the identified table creation data, a stop control table corresponding to the game state of the game, the internal winning situation, and the other reels stop situation is created. Then, it is created for each rotating reel (step S705), and the work initialization code at the time of completion of stop preparation is set in the register (step S706). Thereby, the operation of the stop buttons 12L, 12C, and 12R becomes valid.

  Next, it is determined whether or not any valid operation of the stop buttons 12L, 12C, and 12R has been detected (step S707). If no stop button operation is detected, it is determined whether a reel rotation error (an error determined when the reel reference position is not detected by the reel sensors 3SL, 3SC, 3SR for a certain period or more) has occurred. (Step S708). If no reel rotation error has occurred, whether or not a further insertion error (an error determined when a medal insertion is detected outside the period during which medal insertion is permitted) has occurred, and a payout error It is determined whether or not an error has occurred (error determined when medal payout is detected outside the period in which medal payout is permitted) (steps S709 and S710). If no error is determined in steps S708 to S710, the process returns to step S707.

  If it is determined in step S709 that a loading error has occurred, or if it is determined in step S710 that a dispensing error has occurred, an error code indicating a loading / dispensing error during reel rotation is set in the register (step S710). In step S711, the process proceeds to predetermined error processing (step S712). If the error is released, the process returns to step S707 again.

  If it is determined in step S708 that a reel rotation error has occurred, an error code indicating the reel rotation error is set in the register (step S713), and the process proceeds to a predetermined error process (step S714). Along with this, the rotation of the reels 3L, 3C, 3R is also temporarily stopped. If the error is released, the process returns to step S703 again, and the rotation of the reels 3L, 3C, 3R is resumed.

  If operation of the stop buttons 12L, 12C, 12R is detected in step S707, the reel motor (any of 3ML, 3MC, 3MR) corresponding to the operated stop button from the reel reference position at that time is detected. The number of steps (the number of steps at the stop operation position) is acquired and set to the work corresponding to the stop reel (step S715). Here, a reel stop command indicating the type of reel to be stopped and the symbols to be stopped for the reel is generated and transmitted to the effect control board 102 (step S716). Thereafter, the process waits until the rotation of the reel (any one of 3L, 3C, and 3R) corresponding to the operated stop button stops (step S717).

  Then, when the rotation of the reel (3L, 3C, 3R) corresponding to the operated stop button is stopped, it is determined whether all of the reels 3L, 3C, 3R are stopped (step S718). If the rotation of the reels 3L, 3C, 3R is not stopped, the process returns to step S705. If the rotation of all the reels 3L, 3C, 3R is stopped, the reel rotation process is terminated and the process returns to the flowchart of FIG.

  As described above, in the reel rotation process, after the rotation of the reels 3L, 3C, and 3R is started, the rotation of the reels for which the stop operation has not been detected is continued until the operation of the stop buttons 12L, 12C, and 12R is detected. Then, on the condition that the operation of the stop buttons 12L, 12C, and 12R is detected, control for stopping the display result on the corresponding reel is performed. Even if the reel rotation temporarily stops due to the occurrence of a reel rotation error, the stop operation is still detected until the operation of the stop button 12L, 12C, 12R is detected after the reel rotation is restarted. Control is performed to stop the display result on the corresponding reels on the condition that the operation of the stop buttons 12L, 12C, and 12R is detected by continuing the rotation of the unreeled reels. This is not the case when the data in the RAM 112 is destroyed and cannot be restored to the original state.

  Next, the winning determination process in step S405 will be described in detail. FIG. 17 is a flowchart showing in detail the winning determination process executed by the CPU 111 in step S405. In the winning determination process, the winning combination corresponding to the gaming state is read in order from the beginning (step S801). Next, it is determined whether or not the symbol combination of the read combination is aligned with any of the five winning lines of the variable display device 2 (in the case of a regular bonus, the middle one winning line) (step S802).

  If the symbol combination of the combination is complete, a winning flag for the combination is set in the RAM 112 (step S803), and the process proceeds to step S804. If the symbol combination of the combination is not complete, the process proceeds to step S804 as it is. In step S804, it is determined whether there is a combination that has not yet been determined as a winning determination among the combinations corresponding to the gaming state. If there is a winning combination that has not yet been determined for winning, the process returns to step S801, and the next winning combination corresponding to the gaming state is read out.

  If all of the combinations corresponding to the game state are targeted for winning determination, it is next determined whether or not a replay winning is made based on whether or not a replay winning flag is set in the RAM 112 (step S805). If a replay prize has been won, a replay game in-progress flag is set in the RAM 112 (step S806). The replay game in-progress flag is deleted when the bet number is automatically set in the next game. Then, the process proceeds to step S816.

  If no replay winning is made, it is determined whether or not the big bonus (1) is won according to whether or not the big bonus (1) winning flag is set in the RAM 112 (step S807). If the big bonus (1) has been won, the big bonus medium flag is set in the RAM 112 and the big bonus (1) winning flag set in the RAM 112 is erased. Further, the RT counter value of the RAM 112 is initialized to 0 (step S808). Then, the process proceeds to step S816.

  If the big bonus (1) has not been won, whether or not the big bonus (2) has been won is determined based on whether or not the big bonus (2) winning flag is set in the RAM 112 (step S809). If the big bonus (2) is won, the big bonus medium flag is set in the RAM 112 and the big bonus (2) winning flag set in the RAM 112 is deleted. Also, the RT counter value in the RAM 112 is initialized to 0 (step S810). Then, the process proceeds to step S816.

  If the big bonus (2) has not been won, whether or not the regular bonus has been won is determined based on whether or not the regular bonus winning flag is set in the RAM 112 (step S811). If the regular bonus is won, the regular bonus medium flag is set in the RAM 112 and the regular bonus winning flag set in the RAM 112 is erased. Further, the RT counter value of the RAM 112 is initialized to 0 (step S812). Then, the process proceeds to step S816.

  If the regular bonus has not been won, it is determined with reference to the symbols stopped on the reels 3L, 3C, 3R whether or not a chance is derived to the variable display device 2 (step S813). If the chance is derived, the game state of the current game (or the game state applied in the next game) depends on whether the regular bonus flag or the big bonus flag is set in the RAM 112, the regular bonus or It is determined whether or not it is a big bonus (step S814).

  If the gaming state is neither a regular bonus nor a big bonus, regardless of the current RT counter value (ie, regardless of whether the current gaming state is a normal gaming state, a short RT, or a long RT) 4 is set as the initial value of the RT counter of the RAM 122, and the gaming state is controlled to the short RT. Here, the reason why 4 is set as the initial value is to secure 3 games as the number of short RT games because the RT counter value is decremented by 1 in the current game in step S913 to be described later. (Step S815). Then, the process proceeds to step S816. If no chance has been derived, or if the gaming state is a regular bonus or a big bonus, the process proceeds directly to step S816.

  In step S816, a winning information command indicating the type of the winning combination is generated based on the winning flag set in the RAM 112 (however, in the case of a loss, the winning flag is not set), and transmitted to the effect control board 102. To do. Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  Next, the payout process in step S406 will be described in detail. FIG. 18 is a flowchart showing in detail the payout process executed by the CPU 111 in step S406. In the payout process, it is determined whether or not there has been a small prize winning accompanied by a medal payout depending on whether or not a winning flag of watermelon, bell, or cherry is set in the RAM 112 (step S901). If the small role is not won, the process proceeds to step S903 as it is.

  If the small role winning is achieved, the number of medals is sequentially paid out by controlling the hopper 80. However, until the number of credits accumulated as data reaches 50, instead of paying out medals, the number of credits is increased (step S902). Then, the process proceeds to step S903.

  In step S903, whether or not the game state of the game is a big bonus is determined based on whether or not the big bonus medium flag (the big bonus (1) medium flag or the big bonus (2) medium flag) is set in the RAM 112. However, when the big bonus (1) or big bonus (2) winning flag is set in the RAM 112, it is a big bonus (1) winning or a big bonus (2) winning in the game, and the game Therefore, even if the big bonus (1) medium flag or the big bonus (2) medium flag is set, it is not determined that the game state is the big bonus. If the game state of the game is not a big bonus, the process proceeds to step S908.

  If it is determined that the big bonus is in progress, the counter provided in the RAM 112 counts the total number of medals paid out after the big bonus starts (step S904). As a result of this count, it is determined whether or not the total number of medals paid out exceeds 465 (step S905). If the total number of medals paid out does not exceed 465, the process proceeds to step S908.

  If the total number of medals paid out exceeds 465, 100 is set as the initial value in the RT counter, and the gaming state after the end of the big bonus is set to long RT. When this process is performed, the process of step S913 is not performed in the current game, so the initial value to be set in the RT counter is 100 (step S906). Further, the big bonus medium flag (the big bonus (1) medium flag or the big bonus (2) medium flag) set in the RAM 112 is deleted, and the counter value for counting the total number of medals paid out is initialized to 0. (Step S907). Then, the process proceeds to step S911.

  In step S908, whether or not the game state of the game is a regular bonus (including a case where a big bonus is provided) is determined based on whether or not the regular bonus flag is set in the RAM 112. However, if the regular bonus winning flag is set in the RAM 112, it is a regular bonus winning in the game, and the game state of the game is not a regular bonus, so the regular bonus flag is set. Even if it is, it is not determined that the regular bonus was in effect.

  If the game state of the game is a regular bonus, the counter provided in the RAM 112 starts the regular bonus (after a new regular bonus starts in the big bonus) The number of digested games and the number of winning games are counted (step S909). As a result of this counting, it is determined whether the number of winning games in the regular bonus has become 8 or the number of digest games in the regular bonus has become 12 (step S910).

  If the number of winning games in the regular bonus is 8 or the number of digested games in the regular bonus is 12, the process proceeds to step S911. If the number of winning games in the regular bonus is not eight and the number of digest games in the regular bonus is not twelve, the process proceeds to step S914. In step S911, the regular bonus flag set in the RAM 112 is erased, and the values of the counters for counting the number of digest games and the number of winning games in the regular bonus are both initialized to zero. Then, the process proceeds to step S914.

  If the game state of the game is not a regular bonus in step S908, it is determined whether the RT counter value in the RAM 112 is 0 (step S912). If the RT counter value is not 0, the RT counter value is decremented by 1 (step S913), and the process proceeds to step S914. If the value of the RT counter is 0, the process proceeds to step S914 as it is.

  In step S914, if the watermelon winning flag, the bell winning flag, the cherry winning flag, and the replay winning flag are set in the RAM 112, these are deleted. The big bonus (1) winning flag, the big bonus (2) winning flag, and the regular bonus winning flag are not erased here and are carried over to the next game. If a winning flag is set in the RAM 112 in step S803, it is deleted.

  Next, based on the big bonus medium flag and the regular bonus medium flag in the RAM 112 and the value of the RT counter, a game state command indicating a game state applied in the next game is generated and transmitted to the effect control board 102. (Step S915). Then, the payout process is terminated, and the process returns to the flowchart of FIG. Here, when returning to the flowchart of FIG. 13, the process in the current one game ends.

  In the repetition of the game as described above, the CPU 111 of the game control board 101 shifts the game state among the normal game state, RT, big bonus, and regular bonus, and issues a command according to the progress of the game. It is transmitted to the production control board 102. On the other hand, the CPU 121 of the effect control board 102 performs an original effect including a short RT possibility notification, a chance effect, and a continuous effect (including a bonus notice) based on a command received from the game control board 101. Yes. Hereinafter, the process of the effect performed by the control on the effect control board 102 side will be described.

  FIG. 19 is a flowchart illustrating processing executed by the CPU 121 of the effect control board 102. On the side of the effect control board 102, it is determined whether or not a command sent from the game control board 101 has been received (step S1001). When any command is received from the game control board 101, the type of the received command is determined (step S1002).

  If the received command type is the winning status notification command transmitted in step S526, first, the winning status indicated by the received winning status notification command (that is, the setting status of the winning flag in the current game) is stored in the RAM 122. Are stored in a predetermined area (step S1003). Next, it is determined whether or not the gaming state stored in the RAM 122 in step S1027 (described later) of the previous game indicates that the number of remaining RT games is 3 or less (step S1004). When the number of remaining RT games is 4 or more, the game state of the current game is long RT.

  Here, first, it is determined whether or not the received winning status notification command indicates winning of a regular bonus, a big bonus (1), or a big bonus (2) (step S1005). If none of the regular bonus, the big bonus (1), and the big bonus (2) has been won, it is determined whether or not the received winning status notification command indicates that the watermelon has been won (step S1006). If the watermelon is not won, there is no possibility that the chance chance is derived even in the long RT, and the process directly returns to step S1001.

  If a regular bonus, a big bonus (1) or a big bonus (2), or a watermelon is won, there is a possibility that a chance will be derived in the long RT, so a predetermined image ( However, it does not directly indicate the possibility of derivation of the chance, but it may display an image that is not displayed in any other case, and may shift from long RT to short RT. SRT possibility notification is performed. Further, an SRT possibility flag is set in the RAM 122 (step S1007). Then, the process returns to step S1001.

  If the number of remaining RT games is 3 or less in step S1004, whether the gaming state stored in the RAM 122 in step S1027 (described later) in the previous game indicates that the number of remaining RT games is 1 or more It is determined whether or not (step S1008). If the number of remaining RT games is 0, that is, if the game state is other than RT, the process directly returns to step S1001.

  If the number of remaining RT games is 1 or more, that is, if 97 games or more are digested in the long RT and the remaining number of games is 1 or more and 3 or less, or a short RT is in progress, a bonus notification flag is set in the RAM 122 Whether or not a bonus notification has already been made in the game before the previous time is determined (step S1009). If a bonus notification has already been made in the previous game, the process directly returns to step S1001. If the bonus notification has not yet been made, according to the number of remaining RT games, an effect for the current game among the continuous effects continued in three games is started, and a continuous effect flag is set in the RAM 122 (step S1010). ). Then, the process returns to step S1201.

  If the received command type is the reel rotation command transmitted in step S704, the information on the stop symbols of the reels 3L, 3C, 3R stored in the RAM 122 in the previous game is cleared (step S1011). Then, the process returns to step S1001.

  If the type of the received command is the reel stop command transmitted in step S716, the symbol is identified by referring to the table of the ROM 123 according to the received reel stop command, and the reel indicated by the reel stop command is stopped. The symbol is stored in the stop symbol table of the RAM 122 (step S1012).

  Next, referring to the stop symbol table, it is determined whether or not all of the reels 3L, 3C, 3R have stopped (step S1013). If any of the reels 3L, 3C, 3R is still rotating, the process returns to step S1001. When all of the reels 3L, 3C, and 3R are stopped, it is determined whether or not the SRT possibility flag is set in the RAM 122 (step S1014). If the SRT possibility flag is not set, the process directly returns to step S1001.

  If the SRT possibility flag is set, the SRT possibility notification performed in step S1007 is terminated, and the SRT possibility flag set in the RAM 122 is deleted (step S1015). Furthermore, with reference to the stop symbol tables 3L, 3C, 3R, it is determined whether or not a chance is derived in the variable display device 2 (step S1016). If the chance is not derived, a chance effect is performed by displaying a predetermined image on the liquid crystal display 4 (step S1017). Then, the process returns to step S1001. If the chance is derived, the process directly returns to step S1001.

  Note that when the regular bonus, the big bonus (1), or the big bonus (2) is won according to the display result of the variable display device 2, the chance is not derived, so the chance effect is performed as the process of step S1017. Will be held once. However, if the regular bonus, the big bonus (1) or the big bonus (2) is won, the chance effect will be forced before the player can recognize the execution of the chance effect by the winning information command received continuously. It is ended, and it is essentially the same as no chance production.

  If the received command type is the winning information command transmitted in step S816, does the winning information command indicate a winning of a regular bonus, a big bonus (1), or a big bonus (2)? It is determined whether or not (step S1018).

  If any regular bonus, big bonus (1) or big bonus (2) win is indicated, the currently running performance (including continuous performance, chance performance, bonus notification, SRT possibility notification) is forcibly terminated (Step S1019). Further, the continuous effect flag set in the RAM 122 is deleted, and the bonus notification flag is deleted. If these flags are not originally set, only the state is maintained (step S1020). Then, the process proceeds to step S1021.

  In step S1021, a bonus winning effect indicating a regular bonus, a big bonus (1) or a big bonus (2) is performed by displaying a predetermined image on the liquid crystal display 4 or the like. This bonus winning effect may be different depending on the type of bonus that has been won. Then, the process returns to step S1001.

  If the regular bonus, the big bonus (1), and the big bonus (2) are not won in step S1018, whether or not the continuous effect is executed depending on whether or not the continuous effect flag is set in the RAM 122. Is determined (step S1022). If the continuous effect is not executed, the process returns to step S1001. If the continuous effect is being executed, the result of the continuous effect for the current game is shown, and the continuous effect flag set in the RAM 122 is deleted (step S1023).

  Next, it is determined whether or not the gaming state stored in the RAM 122 in step S1027 of the previous game indicates that the number of remaining RT games is 1 (step S1024). If the number of remaining RT games is not 1, the RT does not end as long as the current game, and a continuous effect is also performed in the next game, so the process returns to step S1001. If the number of remaining RT games is 1, it means that the RT is completed only for the current game, and the normal game state is reached in the next game.

  In this case, it is determined whether or not the winning status stored in the RAM 122 in step S1003 indicates winning of any of the regular bonus, the big bonus (1), or the big bonus (2) (step S1025). If any of the regular bonus, the big bonus (1), and the big bonus (2) is not indicated, the process directly returns to step S1001. If the winning of regular bonus, big bonus (1) or big bonus (2) is indicated, a predetermined image is displayed on the liquid crystal display 4 to inform the player of the winning of these roles. A bonus notification flag is set in the RAM 122 (step S1026). Then, the process returns to step S1001.

  If the received command type is the gaming state command transmitted in step S915, the gaming state indicated by the received gaming state command (that is, the gaming state in the next game) is stored in a predetermined area of the RAM 122. (Step S1027). Then, the process returns to step S1001.

  If the received command type is another command, processing corresponding to the type of each command (the details are omitted because it is not related to the present invention) is executed (step S1028). Thereafter, the process returns to step S1001.

  As described above, in the slot machine 1 according to this embodiment, the long RT that continues for 100 games and the short RT that ends in 3 games are used as RTs that increase the replay winning probability compared to the normal gaming state. There is. Here, for example, even when the number of remaining RT games is controlled by the long RT and there are 4 or more games, if the chance is derived as the display result of the variable display device 2, the short RT is controlled and the RT is The number of games until the end is reduced.

  However, chances of shifting the gaming state to short RT may be derived only when the regular bonus, big bonus (1) or big bonus (2), and / or watermelon is won. is there. Here, if there are four RT games or more in the long RT and these roles are won, the liquid crystal display 4 will notify the possibility of SRT. The SRT possibility notification does not directly indicate the possibility of transition to the short RT, but since it is not performed under other conditions, the player has 4 or more games remaining in the long RT. It can be recognized that there is a possibility of transition from the state to the short RT.

  Further, the chances of shifting the gaming state to the short RT are derived only in the case of regular bonus, big bonus (1) or big bonus (2), and / or a case where a watermelon is missed. Even in the case of these missed cases, the “cherry” is further stopped on the left reel 3L (if it is stopped as the second and third reels, it can be stopped on the winning line where “watermelon” stops). It is limited, and it is possible to prevent the chance eye from being derived by the operation procedure of the stop buttons 12L, 12C, and 12R.

  For this reason, the player can maintain the gaming state in the long RT by operating the stop buttons 12L, 12C, and 12R even when the gaming state may be controlled to the short RT. Also here, the player's technical intervention works to improve the fun of the game. In addition, unless the regular bonus or the big bonus has a game state, the strategy in the game of maintaining the long RT as much as possible is enhanced, so that the interest of the game can be further improved.

  In addition, since the chance of deriving the chance will affect the control of RT, when the regular bonus, the big bonus (1) or the big bonus (2), and / or the watermelon is missed. In addition to simply indicating the possibility of winning the regular bonus, the big bonus (1), or the big bonus (2), the role that can be derived can be given a role. For this reason, it is possible to further increase the player's interest in whether or not a chance is derived as a display result of the variable display device 2, and to further enhance the interest of the game.

  Furthermore, when the chance chance is not derived when the SRT possibility notification is performed, a chance effect is performed (if a regular bonus, a big bonus (1) or a big bonus (2) is won, a game Because it is immediately forcibly terminated before the person recognizes it, there is virtually no chance effect). Even if the chance is not derived, it is highly possible that the regular bonus, the big bonus (1) or the big bonus (2) has been won because the SRT possibility notification has been made.

  For this reason, it is possible to enhance the player's expectation for winning the regular bonus, the big bonus (1), or the big bonus (2) even by the chance effect, so that the interest of the game can be further improved. On the other hand, the player's expectation that the long RT will be continued without shifting to the short RT can be further enhanced by this chance effect, and the interest of the game can be further improved.

  By the way, when the chance chance is derived, the gaming state is controlled to the short RT, but the fact that the chance opportunity has been derived can only be considered a win of watermelon, so regular bonus, big bonus (1) Or the big bonus (2) is likely to be won. Opportunities are regular bonuses, big bonuses (1) or big bonuses (2), and / or outcomes that are derived at the time of winning a watermelon, so during chance RTs and short RT controlled based on this In the continuous performance to be executed, it is possible to give the player an appropriate sense of expectation for winning the regular bonus, the big bonus (1), or the big bonus (2).

  In addition, during the three games controlled by the short RT for which the continuous performance is performed, the replay winning probability is high, and the regular bonus, the big bonus (1) or the big bonus (2) is won. Even if the replay derivation is given priority, the possibility of winning these combinations becomes very low regardless of the operation procedure of the stop buttons 12L, 12C, and 12R.

  Thus, even if the regular bonus, the big bonus (1) or the big bonus (2) is won, the possibility of winning is reduced during the three games of short RT, so not only one game but three games It is possible to continuously give the player a sense of expectation and improve the interest of the game. If the regular bonus, the big bonus (1) or the big bonus (2) is actually won at the end of the continuous performance, a bonus announcement will be made, so that the player's expectation will be further enhanced. Interest can be improved.

  Further, the short RT is shifted to when the chance is derived to the variable display device 2, but the long RT is shifted to when the big bonus is ended. For this reason, even after the big bonus has ended, 100 games can be played at RT where the medal payout rate exceeds 1, so that the player can continue to the next big bonus without reducing his or her medals after the big bonus ends. Or, since the number of cases where a regular bonus can be reached increases, it is possible to increase the player's expectation and further enhance the interest of the game. On the other hand, since the long RT is not controlled even if the regular bonus is ended, it is possible to further increase the expectation of the player who wants a big bonus as a bonus type rather than the regular bonus.

  Furthermore, RT not only has a replay winning probability higher than the normal gaming state, but also has a medal payout rate exceeding 1 unlike the normal gaming state. Therefore, even if the regular bonus, big bonus (1) or big bonus (2) is won when the gaming state is RT, the regular bonus, big bonus (1) or big bonus (2 ) It is better to advance the game without winning a prize. For this reason, when the SRT possibility notification is made by winning the regular bonus, the big bonus (1) or the big bonus (2), a skill is required that neither wins nor derives a chance. Therefore, the technical intervention of the player is very high, and the interest of the game can be further improved.

  In addition, the long RT controlled after the end of the big bonus is a gaming state in which the replay winning probability is extremely high like the short RT, and for a while after the end of the big bonus, a replay is awarded in many games. Become. Here, the regular bonus, the big bonus (1), or the big bonus (2) is not won in the same game as the replay having a very high winning probability, so when the display result of the loss is derived to the variable display device 2, This means that you may have won these bonus combinations in the game. Therefore, even if the result of losing is derived especially in the long RT, the player can be expected to win the regular bonus, the big bonus (1) or the big bonus (2) without disappointing the player. Become.

  By the way, the big bonus ends when the number of medals paid out exceeds 465, regardless of the number of digest games. Here, in a game with a big bonus (including a small role game and a regular bonus), since replay is not defined as a target character for internal lottery, no replay is won. Replay does not reduce the number of medals held by the player, but does not accompany the payout of medals, and therefore does not affect the number of payout medals, which is a condition for terminating the big bonus. In other words, even if you make a replay win during the big bonus, it will only increase the number of big bonus games unnecessarily, so by not defining the replay as a target for internal lottery in the big bonus, The game can be efficiently advanced without unnecessarily prolonging the state.

  Further, when the gaming state is controlled to the big bonus, if the regular bonus medium flag is not set in the RAM 112 when the start lever 11 is operated, the regular bonus medium flag is newly set at this time, and the gaming state Is controlled to a regular bonus. Thus, the big bonus can be provided by repeating the regular bonus until the number of payout medals reaches the specified number, and the player can obtain the maximum profit in the big bonus. Moreover, even when the regular bonus is controlled first after the big bonus (1) or the big bonus (2) is won, the regular bonus is controlled again when the regular bonus for one time has ended and the big bonus has not ended yet. In this case, the same processing is performed.

  In addition, all the reels rotate among a plurality of stop control tables in which stop positions (display results) are uniquely determined with respect to stop operation positions (areas assigned to the number of steps from the reel reference position). In the middle, a stop control table uniquely determined for the internal winning state for each gaming state is selected, and reel stop control is performed according to the selected stop control table. On the other hand, if any of the reels has already stopped, select a stop control table uniquely defined for the internal winning state for each gaming state, the stop position of the stopped reel, The reel stop control is performed according to the selected stop control table, and all of the gaming state, the internal winning state, and the reel stop state (and the stop position of the stopped reel (display result)) are the same condition. When this happens, reel stop control is performed based on the same stop control table, that is, the same control pattern. Therefore, as in the prior art, one stop control table is further selected from a plurality of stop control tables for one internal winning state by a lottery different from the internal lottery (for example, a lottery lottery for reel control, etc.). This is unnecessary, and the control for stopping the reel does not become complicated.

  As described above, the storage address of the judgment value number of each lottery target role registered in the role-specific table for each gaming state may differ depending on the set value, but regardless of the set value. For the combination having the same winning probability, the number of determination values is stored in common regardless of the set value. By storing the number of determination values in common in this way, the storage capacity required for that is reduced. However, in the role-specific table, even if the target number of the internal lottery is the same as the number of bets set and the address storing the number of judgment values referenced according to the set value is different, it is stored at a different address. In some cases, the number of determination values is the same.

  In general, in the development stage, the simulation is performed while adjusting the number of determination values according to the set values for at least some of the combinations (that is, adjusting the winning probability of internal lottery). As the initial number of determination values, a different number of determination values is registered according to the set value. However, as a result of adjustment by simulation, the number of determination values when the set values are different may be the same. Although the same number of judgment values was registered as the initial number of judgment values according to the set value, the number of judgment values registered from the beginning may be used as it is depending on the result of simulation (result of simulation). The number of judgment values different from the initial value, that is, the number of judgment values may differ depending on the set value). Then, the number of determination values obtained with an appropriate result in the simulation in each case is selected as the number of determination values to be set for the mass production model.

  Here, even if the number of determination values adjusted by the simulation is the same regardless of the set value, the determination value number is stored in the ROM 113 by the same address assignment as the address assignment in the development stage. It can be used as a model for mass production. For this reason, it is not necessary to change the method for storing the number of judgment values in the model for mass production from the model for development, so that development from the initial design stage to the model for mass production can be easily performed. Become.

  In addition, the internal lottery adds the number of judgment values of each role referred from the role-specific table to the acquired random number for internal lottery, and depending on whether or not the result of the addition overflows, Judgment is made on whether or not there is a win. For this reason, an internal lottery can be performed using the number of determination values of each combination as it is. It should be noted that when the winning determination table is generated before the actual winning determination is made, the loop processing is required twice, but according to this embodiment, the loop processing in the lottery processing is only required once. Thus, the processing efficiency in the entire lottery process is high.

  In addition, the number of determination values in the normal gaming state or RT is registered for lottery for both the regular bonus, the big bonus (1), or the big bonus (2) and the watermelon. Here, if none of the regular bonus winning flag, big bonus (1) winning flag, and big bonus (2) winning flag has been carried over from the previous game, depending on the value of the random number for internal lottery, Both the big bonus (1) or the big bonus (2) and the watermelon will be won.

  Here, even if the watermelon is won based on the display result of the variable display device 2 based on the watermelon winning flag set based on the winning of the watermelon that is one of the lottery objects, the regular bonus winning flag, the big bonus There is a possibility that either (1) a winning flag or a big bonus (2) a winning flag is set. For this reason, even when winning a watermelon, the player can be expected to win the regular bonus, the big bonus (1), or the big bonus (2), and the interest of the game can be improved.

  The random number for internal lottery acquired by the random number acquisition process is not used as it is from the random number generation circuit 115 by the sampling circuit 116 but is used after being processed by software. The random number generation circuit 115 generates a random number by updating at a high speed with the frequency of the pulse signal of the pulse generation circuit 115a. However, in the random number for internal lottery processed by software, the periodicity of the update is increased by the processing. It will be lost.

  On the other hand, in the internal lottery, by sequentially adding the number of determination values corresponding to each combination to the value of the random number for internal lottery, the value of the random number for internal lottery winning each combination is It will harden. On the other hand, it is possible to prevent the player from aiming as much as possible by losing the periodicity of the random numbers for internal lottery by processing by software and varying the values.

  Moreover, the frequency of the pulse signal generated by the pulse generation circuit 115a to update the values of the counters 115b and 115c of the random number generation circuit 115 is higher than the frequency of the operation clock of the CPU 111, and is not an integral multiple. For this reason, the update of the random number generated by the random number generation circuit 115 becomes difficult to synchronize with the processing performed by the CPU 111. In addition, by increasing the frequency of the pulse signal of the pulse generation circuit 115a, the update speed of the random number generated by the random number generation circuit 115 can be made extremely fast.

  On the other hand, the processing of random numbers by software is performed by replacing the upper byte and lower byte of the random number extracted from the random number generation circuit 115 by the sampling circuit 116, masking the 15th and 7th bits, and then bit-shifting the upper byte. Good. Therefore, even for a relatively large random number of 16 bits (actually masked 14 bits), the load required for processing necessary to lose periodicity is not so large, and can be easily obtained. Can do. Since a large random number can be acquired in this way, the probability setting in the internal lottery can be finely performed.

  Further, in the slot machine 1 according to this embodiment, when an abnormality occurs in the data stored in the RAM 112, it is controlled to the RAM abnormality error state, the progress of the game is disabled, and the setting change mode is set. If the setting value is not newly selected and set based on the setting change operation, the state where the progress of the game is disabled is not released. That is, even if an abnormality occurs in the data stored in the RAM 112, the setting value selected and set based on the setting change operation (in general, the setting value) is not set automatically by the slot machine 1. Since the change operation is performed by an employee of the game shop, it is ensured that the game is played based on the setting value selected by the game shop), so that the game can be fair.

  In addition, when determining whether or not to win the winning combination in the internal lottery, the set value stored in the set value work 112-4 must be an appropriate value (a value in the range of 1 to 6). For example, instead of deciding whether or not to win based on a probability based on a default setting value (for example, setting 1), in this case as well, the game is controlled to a RAM abnormal error state and the progress of the game is disabled. The state where the progress of the game is disabled is not canceled unless the setting change mode is entered and the setting value is newly selected and set based on the setting changing operation. Similarly, when the betting number is not an appropriate value, the RAM abnormal error state is controlled. In other words, even if it is not possible to properly determine whether or not to win the winning lot in the internal lottery, the game will be played again based on the setting value selected and set based on the setting change operation. Is secured, so that the fairness of the game can be achieved.

  Further, the data stored in the RAM 112 is abnormal in most cases when the control cannot be continued due to a malfunction in the control such as a power failure or the control unit 110 running away. Since it is determined whether or not the data is normal only when the control unit 110 is activated after recovering from these states, the determination whether or not the data stored in the RAM 112 is normal is abnormal. Can only be done in situations where there is a high probability that That is, in a situation where there is a low possibility that an abnormality has occurred in the data stored in the RAM 112, it is not necessary to perform the determination, and the load on the control unit 110 can be reduced.

  In particular, in the power interruption interrupt process executed by the input of the voltage drop signal generated when the power is cut off, the RAM parity is calculated based on the data stored in the RAM 112 and stored in the parity storage area 112-7. At the next startup, the RAM parity obtained by the calculation is compared with the RAM parity stored in the parity storage area 112-7 to determine whether the data in the RAM 112 is normal. is doing. In this way, it is possible to determine whether or not the data in the RAM 112 is normal only by comparing the RAM parity at the time of input of the voltage drop signal generated when the power is shut off and at the time of startup, so that the determination is performed accurately and simply. Can do.

  In addition, when an abnormality occurs in the data of the RAM 112 and the progress of the game is disabled, a setting change mode in which a setting value changing operation that becomes a condition for releasing the disabled state of the game is enabled The data stored in the RAM 112 is initialized in accordance with the transition to (setting change processing). For this reason, the initialization of data associated with the occurrence of an abnormality in the data in the RAM 112 and the initialization of data associated with selection / setting of the set value can be performed at one time, so that useless processing can be omitted. .

  Further, when the control unit 110 is activated, it is determined whether or not the setting key switch 92 is ON before determining whether or not the data in the RAM 112 is normal. At that time, the setting key switch 92 is If it is determined that the data is in the ON state, the process proceeds to the setting change mode without determining whether the data in the RAM 112 is normal. In this way, a new set value is selected and set without determining whether or not the data in the RAM 112 is normal, so that useless processing can be omitted.

  The present invention is not limited to the above-described embodiment, and various modifications and applications are possible. Hereinafter, modifications of the above-described embodiment applicable to the present invention will be described.

  In the above embodiment, the gaming state is controlled to the long RT after the big bonus is finished, but the gaming state may be controlled to the long RT after the regular bonus is finished. The gaming state may be controlled to the long RT after either the big bonus or the regular bonus ends. Further, when a predetermined condition other than the end of the big bonus or the regular bonus (for example, a predetermined display mode other than the above-described winning display result or chance is derived to the variable display device 2) is satisfied, The gaming state may be controlled by RT.

  In the above embodiment, the SRT possibility notification is performed only when the number of remaining RT games is 4 or more. That is, even if the regular bonus, the big bonus (1) or the big bonus (2), and / or the watermelon are won, the SRT possibility notification is not performed when in other gaming states. However, when the regular bonus, the big bonus (1) or the big bonus (2) and / or the watermelon are won in a gaming state other than the regular bonus or the big bonus, that is, the gaming state is newly controlled to the short RT. When there is a possibility, all may be notified of the possibility of SRT.

  In this case, when the SRT possibility notification is performed, the player may not know whether the game state is normal or RT (particularly long RT). If the game state is normal, it is more advantageous for the player to derive the chance than to derive the miss because the game state is controlled to RT even with only three games. Here, if the chance is lost when the chance button is removed by operating the stop buttons 12L, 12C, and 12R, it is better that the player does not intentionally remove the chance eye.

  However, derivation of chances is conditional on a regular bonus, a big bonus (1) or a big bonus (2), and / or a watermelon win. In the former case, if the winning combination can be won according to the operation procedure of the stop buttons 12L, 12C, 12R, the gaming state is controlled to the regular bonus or the big bonus, so that the player loses. Absent. If the reach is derived according to the operation procedure of the stop buttons 12L, 12C, 12R even if the winning is not possible, the regular bonus, the big bonus (1) or the big bonus (2) can be confirmed early here. Therefore, even if it is not controlled by the short RT, it cannot always be said that the player loses.

  Even in the latter case, if the watermelon can be won according to the operation procedure of the stop buttons 12L, 12C, and 12R, nine medals can be paid out. Since the number of bets set per game in the normal gaming state is 3, at least 3 games can be played with the paid-out medals. For this reason, even if the chance is deliberately removed, the player will not lose as long as the watermelon can be won.

  In the above embodiment, the SRT possibility notification does not directly indicate the possibility of derivation of the chance eye, but may be displayed except when there is a possibility that the chance eye is derived in the long RT. The predetermined image is not displayed on the liquid crystal display 4. On the other hand, it may be notified directly that there is a possibility that the chance chance is derived in the long RT. It is good also as what alert | reports the symbol which can avoid derivation | leading-out of a chance opportunity, such as "Aim at watermelon" and "Aim at BAR." The SRT possibility notification is not only performed when an image is displayed on the liquid crystal display 4, but for example, a predetermined start sound is output when the start lever 11 is operated, or lamps are displayed in a predetermined pattern. It is good also as what is performed by making it light.

  In the above embodiment, the gaming state is controlled to the short RT by derivation of the chance item, but this chance item is given to the regular bonus, the big bonus (1) or the big bonus (2), and / or the watermelon. In the case of winning, it is derived in accordance with the operation timing of the stop button 12L. However, the operation procedure of the stop buttons 12L, 12C, and 12R for deriving chance chances when the regular bonus, the big bonus (1) or the big bonus (2) and / or the watermelon is won is not limited to this. Alternatively, the chances may be derived according to the order in which the stop buttons 12L, 12C, and 12R are operated. It can also be combined with the operation timing of the stop buttons 12L, 12C, 12R.

  For example, when a forward push operation is performed in which the stop buttons 12L, 12C, and 12R are sequentially operated from left to right, chances are always derived, but when a reverse push operation is performed from right to left. It is also possible that no chance eyes are derived. Further, when the stop buttons 12L, 12C, and 12R are operated in order, a chance is always derived for the day. However, when the stop buttons 12L, 12C, and 12R are operated in reverse, the chance is determined according to the operation timing of the stop buttons 12L, 12C, and 12R. The eyes may be derived. In addition, when the stop buttons 12L, 12C, and 12R are operated in order, a chance is derived according to the operation timing of the stop buttons 12L, 12C, and 12R. The eyes may not be derived. Furthermore, even if the stop buttons 12L, 12C, and 12R are forward pressed and reversely pressed, chances are derived according to the operation timing of the stop buttons 12L, 12C, and 12R. The operation timing for deriving the chance eye may be greater than the operation timing for deriving the chance eye by the reverse pressing operation.

  In the above embodiment, there is a case where a chance bonus is derived by the regular bonus, the big bonus (1), the big bonus (2), or the watermelon missing, and the gaming state is controlled to the short RT by deriving the chance bonus. I was supposed to. However, the outcome of controlling the gaming state by the short RT is derived only by missing the regular bonus, the big bonus (1) or the big bonus (2), even if it is derived only by missing a small role such as a watermelon. It is good also as a thing.

  If the game state is controlled to the short RT with the outcome derived only by missing a small role such as a watermelon, even if a regular bonus, a big bonus (1) or a big bonus is won, a continuous performance may be performed. Good. In this case, the continuous performance can also make the player expect the winning of the regular bonus, the big bonus (1), or the big bonus (2).

  In this case, the gaming state is controlled to the short RT by winning the regular bonus, the big bonus (1) or the big bonus (2) in the normal gaming state (or the outcome that appears when not winning them). It is good. After winning the regular bonus, the big bonus (1) or the big bonus (2), it will be a short RT or long RT unless they win, so the regular bonus, big bonus (1) or big bonus (2 ) As long as possible, it is possible to effectively produce a continuous performance.

  In addition, when the outcome that controls the gaming state in the short RT is a reach eye derived by losing a regular bonus, a big bonus (1), or a big bonus (2), this reach eye is a regular bonus, a big bonus ( 1) or a big bonus (2) winning announcement (that is, a 100% winning announcement). The continuous performance performed here is also a bonus notification. In any case, there is no change in that the continuous production is expected to win the regular bonus, the big bonus (1) or the big bonus (2). The same applies to chance production.

  Note that even if the outcome of controlling the gaming state in the short RT is only reach, the significance as the present invention is not lost as long as the medal payout rate in the long RT exceeds 1. In other words, the regular bonus winning flag, the big bonus (1) winning flag and the big bonus (2) winning flag are carried over until winning, so as long as the gaming state is long RT, even if the player has intentionally dropped them, This is because there is no loss, and the player can benefit from an increase in medals in long RT.

  In the above embodiment, the chance effect is performed on the condition that the SRT possibility notification is performed and the chance eye is not derived, but this chance effect is for the player to continue the long RT. It was performed not only to make people expect, but also to make players expect to win regular bonus, big bonus (1) or big bonus (2). However, the regular bonus, the big bonus (1) or the big bonus (2) can be expected even when the chance chance is derived, regardless of whether or not the SRT possibility notification is performed. Therefore, even when a chance chance is derived as a display result of the variable display device 2, a chance effect may be performed. Of course, there is an objective that the long RT can be expected to continue when the SRT possibility notification is made and the chance eyes are not derived. Therefore, the mode of the chance effect performed at this time is when the chance eyes are derived. It is good also as a thing different from the aspect of the chance effect |

  In the above embodiment, all of the chances derived when the regular bonus, the big bonus (1) or the big bonus (2), and / or the watermelon are won are those that cause the short RT to control the gaming state. Met. On the other hand, it is derived when a regular bonus, a big bonus (1) or a big bonus (2), and / or a watermelon is won. There may be a chance to control the gaming state and a chance not to control the short RT. Which is derived can be determined by operating procedures of the stop buttons 12L, 12C, and 12R.

In the above embodiment, in 3 games after the chances are derived or 100 games after the end of the big bonus (however, the chances are derived or the regular bonus, the big bonus (1) or the big bonus (2) is won) Until the game state is controlled to RT. In RT, the winning probability of a role other than replay is the same as in the normal gaming state, but the replay winning probability is higher than in the normal gaming state, so that the gaming state is more advantageous for the player than in the normal gaming state. It was a thing. Of course, as a gaming state that is more advantageous than the normal gaming state other than the regular bonus or the big bonus, the operating procedure of the stop buttons 12L, 12C, and 12R for winning a winning combination in the internal lottery is announced ( A stop button that allows the player to recognize the operation timing of the stop buttons 12L, 12C, and 12R for notifying the winning combination by announcing the type of winning combination itself, or enabling or facilitating winning of the winning combination 12L, 12C, and 12R operation state (so-called AT) may be used. AR which combined RT and AT may be sufficient.

  In the above embodiment, the continuous production is only performed according to the number of games from the start, and the production has different contents depending on the winning status of the regular bonus, the big bonus (1) or the big bonus (2). It never became. On the other hand, when starting the continuous production, the production pattern selected according to the winning situation of the regular bonus, the big bonus (1) or the big bonus (2) is selected, and the continuous production is performed according to the selected production pattern. It is good also as what produces each game in the period which should be performed, and alert | reports the presence or absence of a bonus winning at the end.

  In this case, a new regular bonus, big bonus (1), or big bonus (2) may be won in the game after the continuous production is started. In this case, after notifying the bonus non-winning in the first selected pattern, the bonus effect can be notified again by executing an additional effect. Further, a part of the selected pattern, for example, the contents of the effect in the last game of the continuous effect can be replaced. Execution of the additional effect and replacement of the content of the effect may be used together, and one of them may be selected. Whether the regular bonus, the big bonus (1) or the big bonus (2) is newly won in the game after the continuous production is started is determined by each game during the continuous production. However, it may be determined after the internal lottery ends in the game where the continuous performance ends.

  In addition, the effect after the gaming state is controlled to the short RT by the derivation of the chance is not limited to the continuous effect that continues between the three games as described above. For example, it can be an effect that ends in only one game, or stops once at the end of one game (derivation of the display result of the variable display device 2 or completion of payout of medals) and bets for the next game. It may be an effect whose result is shown when a number is set (when the game has not yet started).

  In the above embodiment, only a bonus winning effect is performed when a regular bonus or a big bonus is won, and a special effect is performed when a regular bonus or a big bonus as a gaming state starts or ends. There was no. On the other hand, for example, when the big bonus is ended, a freeze effect may be performed in which all effects are stopped while controlling to a freeze state in which the progress of the game is disabled for a certain period of time. This freeze effect can also be performed at the start of the big bonus, that is, immediately after winning the big bonus (1) or the big bonus (2). Regardless of whether the freeze effect is performed at the end of the big bonus or the freeze effect is performed at the start of the big bonus, only the payment of the credit can be performed by operating the settlement button 16. Further, the stop control may be performed at the end of the big bonus. Even when the stop control is performed, only the credit settlement can be performed as in the case where the freeze effect is performed.

  In the above embodiment, when some of the three reels 3L, 3C, 3R are already stopped, the internal winning state for each gaming state and the stop position of the stopped reel are unique. A stop control table that is determined in a specific manner is selected, and reel stop control is performed in accordance with the selected stop control table. Here, instead of the stop position of the stopped reel, the position when the stop buttons 12L, 12C, and 12R are operated to stop the reel (that is, the number of steps of the reel) may be applied. Good. Also in this case, similarly to the selection of the stop control table in the above embodiment, it is possible to obtain an effect that the control for stopping the reel does not become complicated.

  In the above embodiment, the number of determination values stored in the address registered in the role-specific table is added to the random number for internal lottery, and when an overflow occurs as a result of the addition, the winning combination is won. I was supposed to. On the other hand, the acquired number of determination values may be sequentially subtracted from the acquired internal lottery random value, and the result of the subtraction may be used as a new internal lottery random value. When the number of determination values is subtracted from the random number value for internal lottery, it can be determined whether or not an overflow has occurred in the subtraction result (here, the subtraction result becomes negative).

  In the above embodiment, the internal lottery sequentially adds the number of judgment values of each combination according to the game situation to the acquired random value for internal lottery, and when the addition result overflows, the winning combination is won. It was supposed to be judged. On the other hand, a winning determination table in which a determination value for determining each combination as winning is determined for each game in accordance with the number of determination values for each combination according to the game situation, and the internal random number for internal lottery acquired It is good also as what performs an internal lottery by comparing this value with the determination value of each combination.

  In the above embodiment, the seventh and fifteenth bits are masked to generate a random number for internal lottery. That is, the random number value for internal lottery is represented by 14 bits and takes a range of 0 to 16383. However, the value represented by 16 bits can be directly applied as a random number for internal lottery without masking the 7th and 15th bits. In this case, the number of determination values for each target part of the internal lottery may be registered in the ROM 113 according to the range of values that the random numbers for internal lottery can take. On the other hand, when the random numbers for internal lottery are generated by masking the 7th and 15th bits as in the above embodiment, the numerical value represented by the masked 2 bits is set as the internal lottery. Can be applied as a random number for making another decision (for example, selecting the type of production). Thereby, all the bits of the random number extracted from the random number generation circuit 115 can be used effectively.

  In the above embodiment, the entire high-order byte of the random number extracted from the random number generation circuit 115 is replaced with the low-order byte, and the whole low-order byte is replaced with the high-order byte. On the other hand, the data of a specific bit among the random number bits extracted from the random number generation circuit 115 is simply replaced with data of other bits (however, other than the masked seventh and fifteenth bits). Also good. Alternatively, the random number value extracted from the random number generation circuit 115 may be directly acquired as a random number for internal lottery. Furthermore, it may be processed into a random number for internal lottery by a method different from the above embodiment.

  FIG. 20 is an explanatory diagram of a first modification of the process (step S102) until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. Also in the first modification, the random number extracted from the random number generation circuit 115 is stored in the 16-bit general-purpose register 111GR included in the CPU 111.

  When the random number extracted from the random number generation circuit 115 is stored in the general-purpose register 111GR, the CPU 111 further extracts the value of the internal refresh register 111R as a processing random number. The CPU 111 adds the processing random number extracted from the refresh register 111R to the value of the upper byte of the general-purpose register 111GR (the value extracted from the upper counter 115c). The lower byte value of the general register 111GR (the value extracted from the lower counter 115b) is left as it is.

  Next, the CPU 111 performs an AND operation on the value of the general-purpose register 111GR, that is, a value obtained by adding a processing random number to the upper byte and 8080h. Further, the CPU 111 shifts the upper 1 byte (8th bit to 15th bit) to the lower bit by bit, and inserts 1 into the empty 15th bit. The CPU 111 acquires the value stored in the general-purpose register 111GR at this time as a random number for internal lottery, and sequentially adds the number of determination values to this.

  FIG. 21 is an explanatory diagram of a second modification of the process (step S102) until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. Also in this example, the random number extracted from the random number generation circuit 115 is stored in the 16-bit general-purpose register 111GR included in the CPU 111.

  When the random number extracted from the random number generation circuit 115 is stored in the general-purpose register 111GR, the CPU 111 further extracts the value of the internal refresh register 111R as a processing random number. The CPU 111 adds the processing random number extracted from the refresh register 111R to the value of the upper byte of the general-purpose register 111GR (the value extracted from the upper counter 115c). The processing random number extracted from the refresh register 111R is also added to the lower byte value (the value extracted from the lower counter 115b) of the general-purpose register 111GR.

  Next, the CPU 111 performs an AND operation on the value of the general-purpose register 111GR, that is, a value obtained by adding a processing random number to the upper byte and the lower byte, respectively, with 8080h. Further, the CPU 111 shifts the upper 1 byte (8th bit to 15th bit) to the lower bit by bit, and inserts 1 into the empty 15th bit. The CPU 111 acquires the value stored in the general-purpose register 111GR at this time as a random number for internal lottery, and sequentially adds the number of determination values to this.

  In the first and second modified examples described above, the value of the refresh register 111R is extracted as a random number for processing, and this is extracted from the high-order byte of the random number extracted from the random number generation circuit 115 (in the second modified example, further lower byte) ) To process random numbers. The random number processing applied here includes at least processing for adding a processing random number to the upper byte. Thereby, the variation of the random numbers for internal lottery can be increased, and the player can prevent the aiming as much as possible.

  Further, since the processing random numbers are extracted from the refresh register 111R, no special configuration is required as means for generating the processing random numbers. Moreover, since the value of the refresh register 111R is updated every time the CPU 111 fetches an instruction, and the update interval is not constant, a random number with high randomness can be extracted as a processing random number. Since the random number for processing is high in randomness, the randomness of random numbers for internal lottery generated using this is also increased.

  In the first and second modified examples, the value extracted from the refresh register 111R is added to the upper byte (and the lower byte) of the random number extracted from the random number generation circuit 115. A value that is periodically updated by hardware or software may be added. Further, instead of adding a value extracted from the refresh register 111R (or a value replacing the refresh register 111R), a logical operation such as subtraction, logical sum, or logical product may be performed.

  Further, bit replacement such as replacement of the upper byte and the lower byte shown in the above embodiment may be used in combination with the first and second modifications. Also in the first and second modified examples, during the period from the extraction of the random number from the random number generation circuit 115 to the end of processing, the interrupt to the CPU 111 is prevented in order to prevent the contents of the general-purpose register 111GR from being rewritten. It will be prohibited.

  Further, in the second modification, processing random numbers to be added to the upper and lower bytes of the random number extracted from the random number generation circuit 115 may be separately extracted from the refresh register 111R at different timings. Separately prepare the processing random number to be added to the upper byte and the processing random number to be updated to the lower byte. Means for extracting may be provided. In this case, one of the means for updating the processing random number for the upper byte and the means for updating the processing random number for the lower byte can be configured by the refresh register 111R.

  In both the above embodiment and the first and second modifications, the seventh and fifteenth bits are masked to generate a random number for internal lottery. That is, the random number value for internal lottery is represented by 14 bits and takes a range of 0 to 16383. However, the value represented by 16 bits can be directly applied as a random number for internal lottery without masking the 7th and 15th bits. In this case, the number of determination values for each target part of the internal lottery may be registered in the ROM 113 according to the range of values that the random numbers for internal lottery can take.

  On the other hand, if the random numbers for internal lottery are generated by masking the seventh and fifteenth bits as in the above embodiment and the first and second modifications, the masked two bits Can be applied as a random number for making a decision different from the internal lottery (for example, selection of the type of effect). Thereby, all the bits of the random number extracted from the random number generation circuit 115 can be used effectively.

  FIG. 22 is an explanatory diagram of a third modification of the process (step S102) until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. In this example, the signal wirings connecting the random number generation circuit 115 and the sampling circuit 116 are connected so that the order of bits is reversed for each of the upper 8 bits and the lower 8 bits. Accordingly, the data latched by the sampling circuit 116 is reverse in the order of bit arrangement for the upper 8 bits and the lower 8 bits with respect to the data signal output by the random number generation circuit 115.

  The CPU 111 fetches numerical data corresponding to the data signal input from the sampling circuit 116 via the I / O port 114 from the sampling circuit 116 separately from the upper 8 bits and the lower 8 bits, and is provided in the RAM 112. Temporarily stored in the random number storage area for internal lottery. The random number storage area for internal lottery is provided for 2 bytes. The upper byte storage area is called the upper area, and the lower byte storage area is called the lower area.

  When the CPU 111 fetches numerical data from the sampling circuit 116, the upper 8 bits of the random number latched by the sampling circuit 116 is taken into the lower area, and the lower 8 bits of the latched random number are taken into the upper area. Therefore, the numerical data taken by the CPU 111 from the sampling circuit 116 into the internal lottery random number storage area is completely in reverse order to the data signal generated by the random number generation circuit 115.

  For the random number latched by the sampling circuit 116 or the random number processed by the CPU 111, the least significant bit is called the 0th bit and the most significant bit is called the 7th bit for each upper byte and lower byte. The data signal output from the random number generation circuit 115 is described as a random number corresponding to the logical value, and the numerical data latched by the sampling circuit 116 is also described as a random number corresponding to the value.

  As described above, when the random number generated by the random number generation circuit 115 is latched by the sampling circuit 116, the bit order of the latched random numbers is reversed for the upper 8 bits and the lower 8 bits ((a) To (b)). The CPU 111 captures the upper 8 bits of the random number latched by the sampling circuit 116 from the upper port into the lower area of the RAM 112 and the lower 8 bits from the lower port into the upper area of the RAM 112 ((b) to (d)). Thus, 16-bit numerical data composed of numerical data taken into the upper area and lower area of the RAM 112 is a random number before processing.

  The data in the lower area is rewritten by the subsequent processing. However, since the data in the lower area of the random number before the processing may be used after that, the data in the lower area before the processing is used as the save data. Save in the save area. Next, the CPU 111 subtracts 11h from the upper area data, and temporarily stores the resulting data in the upper area (e). Next, data in the upper area is read, the data is rotated bit by bit to the lower (right), and the resulting data is temporarily stored in the upper area (f).

  Next, an exclusive OR operation is performed on the upper area data and the lower area data bit by bit, and the resulting data is newly stored in both the upper area and the lower area (g). Further, the saving area data 78h is added, and the resulting data is temporarily stored in the saving area (h). Then, an exclusive OR operation is performed on the upper area data and the save area data for each bit, and the resulting data is newly stored in the upper area (i). At this time, numerical data in which the data stored in the upper area is the upper 8 bits and the data stored in the lower area is the lower 8 bits is acquired as a random number for internal lottery (j).

  Here, the random number for internal lottery finally generated here appears almost randomly every time a pulse signal is input. That is, both continuity and periodicity are eliminated. Here, it is assumed that a state in which values are completely continuous, such as the numerical value of the random number generation circuit 115, approaches a state in which discontinuous values appear randomly. For example, any one of the change from the numerical value of the random number generation circuit 115 to the numerical value of the sampling circuit 116, the change from the numerical value of the sampling circuit 116 to the random number before processing, and the change from the random number before processing to the random number for internal lottery. Corresponds to those whose values vary. The same is true for variations and variations.

  In the third modification, 11h is subtracted from the upper area data before performing the final exclusive OR operation (FIG. 22 (i)) of the upper area data and the lower area data (FIG. 22). 22 (e)), rotate 1 bit lower (FIG. 22 (f)), perform exclusive OR operation with lower area data (FIG. 22 (g)), and process upper area data in advance. However, not all of these are necessarily required, and any one or two of them can be applied, and there is no need to process the data in the upper area before the final exclusive OR operation. Good. The upper area data at this time may be the final upper byte data in the random number for internal lottery. The order in which the processes of FIGS. 22E to 22F are performed can be changed to an arbitrary order.

  In addition, the value to be subtracted in FIG. 22 (e) is not limited to 11h, and any value other than 00h can be added or subtracted. In FIG. 22 (f), the rotation is limited to 1 bit in the lower order. It can be rotated up or down by any number of bits up to 7 bits. The data in the lower area subjected to the exclusive OR operation in FIG. 22G may be data obtained by performing a predetermined operation on the data first input to the lower area from the random number generation circuit 115. As a calculation performed on the data in the upper area, a calculation by an arithmetic expression other than this can be applied. Furthermore, the data in the save area that is subjected to the exclusive OR operation on the data in the upper area in FIG. 22 (i) may be data that is first input to the lower area from the random number generation circuit 115. Data obtained by performing a predetermined calculation different from (e) to (g) may be used.

  Further, the final lower byte data in the random numbers for internal lottery may be the data that is first input from the random number generation circuit 115 to the lower area as it is. The data in the save area after adding 78h in FIG. 22 (h) may be used as the final lower byte data in the random number for internal lottery. Alternatively, 78h may be added to the data of the result of the exclusive OR operation stored in the lower area in FIG. 22 (g) to obtain the final lower byte data. Furthermore, as a calculation to be performed on the data in the lower area, a calculation based on another calculation formula may be applied, and the calculation result may be the final lower byte data in the random number for internal lottery.

  When the instruction set of the CPU 111 is the 2-address system or the 3-address system, 11h is subtracted from the data stored in the upper area of the RAM 112, and the data of the subtraction result is stored in the upper area. The data stored in the upper area of the RAM 112 and the data stored in the lower area of the RAM 112 are exclusive ORed, and the data of the result of the exclusive OR operation is stored in the upper area. be able to.

  On the other hand, when the instruction set of the CPU 111 is the one-address method, for example, when subtraction as shown in FIG. 22 (e) is performed, the data stored in the upper area of the RAM 112 is first stored in an accumulator (general-purpose register). ), 11h is subtracted from the accumulator data, and the subtraction result data is stored again in the accumulator. Here, when the data stored in the upper area of the RAM 112 is loaded into the accumulator, the accumulator effectively acts as the upper area. Here, the accumulator still operates on the data in the upper area. It is not necessary to store the data in the upper area of the RAM 112 yet.

  In FIG. 22 (f), the accumulator data in which the result of the subtraction in FIG. 22 (e) is stored is rotated to the lower bit by bit, and the resulting data is stored again in the accumulator. In FIG. 22 (g), an exclusive OR operation is performed on the data stored in the lower area of the RAM 112 for each bit with respect to the accumulator data in which the result of the operation of FIG. 22 (f) is stored. Is stored in the accumulator. At this point, since the accumulator is still functioning as the upper area of the RAM 112, the accumulator data may be stored in the lower area of the RAM 112 in FIG. 22 (g) → (j).

  Furthermore, in FIG. 22 (h), the data in the save area of the RAM 112 is loaded into the accumulator. Here, the accumulator functions as a save area, and 11h is added to the accumulator data and stored in the accumulator. In FIG. 22 (i), the data of the accumulator is exclusive ORed with the data in the upper area of the RAM 112 for each bit, and the result is stored in the accumulator, but the result of the exclusive OR operation is stored. After that, the accumulator again acts as the upper region.

  Thus, the accumulator in the CPU 111 having a one-address instruction set acts as any of the upper area, the lower area, and the save area depending on the data stored in the calculation process (although as described above) In the random number processing method, the accumulator does not act as a lower region). Similarly, the stack in the CPU 111 having the instruction set of the 0 address system also functions as any of the upper area, the lower area, and the save area depending on the data stored in the calculation process.

  Further, if the CPU 111 has a plurality of general-purpose registers, the RAM 112 may not be provided with an upper area and a lower area, but any two general-purpose registers may be applied as the upper area and the lower area. In particular, if the CPU 111 has a 2-byte general-purpose register in addition to the 1-byte general-purpose register, it may be used for the upper area and the lower area.

  In the RAM 112, the same upper area and lower area are used both for the area for storing the 2n-bit numerical data fetched from the sampling circuit 116 and for the area for storing the finally generated random numbers for internal lottery. However, separate areas may be used. For example, if a 2-byte random number area that stores the finally generated random numbers for internal lottery is provided separately from the upper and lower areas, the upper area data is stored in the lower bytes of the random area. Then, the result data of the exclusive OR operation of FIG. 22 (i) may be stored in the upper byte of the random number area.

  In the third modified example, the number of random numbers for internal lottery is 16 bits which is the same as the number of random numbers generated by the random number generation circuit 115 and takes a value of 0 to 65535. . In this case, the number of determination values for each combination may be a value corresponding to the size of the random number (for example, four times that in the above embodiment). Simultaneously with the generation of the random number in the above embodiment, a part of the 16 bits (in the above embodiment, the 7th bit and the 15th bit) are thinned, so that a random number for internal lottery can be obtained. The range of possible values may be smaller than this. The thinned 2-bit numerical value can be used for lottery of other processes (for example, effects for bonus notification). Thereby, the thinned bit value can also be used effectively.

  The method for generating random numbers for internal lottery in the third modified example can change the processes in FIGS. 22A to 22D as shown in FIGS.

  In the example of FIG. 23, the random number generated by the random number generation circuit 115 is replaced with the upper 8 bits and the lower 8 bits in the same manner as in the case of FIGS. (A) to (b). Next, the upper 8 bits of the random number taken by the sampling circuit 116 are taken into the upper area of the RAM 112 via the upper port, and the lower 8 bits are taken into the lower area of the RAM 112 via the lower port (b) to (d). Thereafter, the numerical data stored in the upper byte and the numerical data stored in the lower byte may be exchanged by software processing to obtain a random number before processing (e).

  Note that the connection order of the wiring between the random number generation circuit 115 and the sampling circuit 116 is reversed, and the arrangement order of the upper byte and the lower byte is not reversed for the random number that is first fetched into the RAM 112. The connection order of the wiring between the circuit 116 and the upper port: lower port is reversed, and the arrangement order of the upper byte and the lower byte of the random number that is first fetched into the RAM 112 is changed to the random number generated by the random number generation circuit 115. The order may be reversed. This point can also be applied to the example of FIG.

  In the example of FIG. 24, the wiring connection between the random number generation circuit 115 and the sampling circuit 116 is not reversed. First, the random numbers generated by the random number generation circuit 115 are converted into the sampling circuit 116 in the bit arrangement order as they are. (A) to (b). Next, the upper 8 bits of the random number taken by the sampling circuit 116 are taken into the upper area of the RAM 112 via the upper port, and the lower 8 bits are taken into the lower area of the RAM 112 via the lower port (b) to (d).

  Thereafter, the numerical data stored in the upper byte and the numerical data stored in the lower byte are switched by software processing (e). Furthermore, the random number before processing may be obtained by switching the bit arrangement order of the numerical data stored in the upper byte and the numerical data stored in the lower byte in reverse order by software processing (f). Note that the numerical data stored in the upper byte and the numerical data stored in the lower byte are first changed to reverse the bit order of the numerical data stored in the upper byte and the numerical data stored in the lower byte. May be replaced later.

  In the example of FIG. 25, the wiring between the random number generation circuit 115 and the sampling circuit 116 is reversed between the upper byte and the lower byte, and is connected so that the bit order does not change in each byte. . Here, the random number generated by the random number generation circuit 115 is taken into the sampling circuit by switching the upper byte and the lower byte (a) to (b). Next, the upper 8 bits of the random number taken by the sampling circuit 116 are taken into the upper area of the RAM 112 via the upper port, and the lower 8 bits are taken into the lower area of the RAM 112 via the lower port (b) to (d).

  Thereafter, the bit order of the numerical data stored in the upper byte and the numerical data stored in the lower byte may be reversed in a software process to obtain a random number before processing (e). Note that the arrangement order of the wiring between the random number generation circuit 115 and the sampling circuit 116 is not changed, and the upper byte of the sampling circuit 116 may be connected to the lower port of the CPU 111 and the lower byte may be connected to the upper port. .

  In the example of FIG. 26, the wiring between the random number generation circuit 115 and the sampling circuit 116 is completely connected in reverse order. Here, the sampling circuit 116 takes in the order of the random number bits generated by the random number generation circuit 115 in the reverse order (a) to (b). Then, the upper byte and lower byte of the random number fetched by the sampling circuit 116 may be fetched as they are into the upper area and lower area of the RAM 112 via the upper port and lower port as they are (b) to (d).

  In addition, the order of bits in each byte in the upper byte and lower byte of the random number for internal lottery in the third modification is not necessarily limited to the reverse order. For example, the highest order in each byte The bit and the least significant bit may be simply exchanged. However, in particular, it is preferable that as many bits as possible be replaced in the upper byte of the random number generated by the random number generation circuit 115 with a small change in value according to the difference in timing.

  In the above embodiment, the case where the present invention is applied to the case where the random number generated by the random number generation circuit 115, that is, the random number extracted by the hardware random number function is processed by software has been described. However, the random number processing by the software described above may be applied to a random number that is periodically updated by software. For example, the microcomputer constituting the control unit 110 is an I / O port that causes the CPU 111 to send an instruction to the second microcomputer to extract a random number periodically updated by a timer interrupt or the like in the first microcomputer. It can be input to the CPU 111 via 114 and stored in the general-purpose register 111GR. The function of the second microcomputer may be included in the microcomputer constituting the control unit 110. Also in this case, the random number value obtained after processing can be varied, and the effect of preventing the player from aiming can be achieved.

  In the above embodiment, the determination value number storage area uses a 2-byte area to store the determination value number in each case. However, in a general slot machine, the number of judgment values for a combination such as a regular bonus, a big bonus (1), or a big bonus (2) may be set to exceed 255 in any gaming situation. Absent. Thus, for those that do not need to set the number of determination values exceeding 255, the number of determination values may be stored using only a 1-byte area.

  In the above embodiment, the number of determination values is stored in common for all of the setting values 1 to 6 or individually stored for each of the setting values 1 to 6. However, it is assumed that the number of determination values is not stored in common for all of the setting values 1 to 6 (the common flag for the setting value is not set). About 4-6, the number of judgment values can also be made common.

  In the above embodiment, in the normal gaming state or RT, the game can be started only by setting 3 as the number of bets. On the other hand, even in the normal gaming state or RT, it is possible to start the game by setting 1 as the number of bets, or to start the game by setting 2 as the number of bets. You may do it.

  When 1 or 2 is set as the bet number in the normal gaming state and RT, the winning probability of the small role in the internal lottery is lowered as compared with the case where 3 is set as the bet number, and when winning the small role The number of paid out medals can be increased. Further, in a slot machine that can set any one, two, or three bets as the number of bets in the normal gaming state and RT, the number of judgment values can only be stored in common for all of the setting values 1 to 6. Rather, it is possible to have a combination that is stored in common for all the bets 1 to 3. In this case, the storage area for the number of determination values can be reduced according to the number of bets, and the storage capacity can be further reduced.

  In the above embodiment, in the game in which the gaming state is the big bonus and the big bonus medium flag (the big bonus (1) medium flag or the big bonus (2) medium flag) is set in the RAM 112, the operation of the start lever 11 is performed. It is sometimes determined whether or not the regular bonus medium flag is set in the RAM 112, and if the regular bonus medium flag is not set, it is set and controlled to the regular bonus. Thus, even when the regular bonus is controlled first after the big bonus (1) or the big bonus (2) is won, the regular bonus is controlled again when the regular bonus for one time is finished and the big bonus is not finished yet. Even in this case, the same processing should be performed.

  On the other hand, when the big bonus (1) or the big bonus (2) is won, a regular bonus medium flag is set in the RAM 112 together with the big bonus medium flag, and when the regular bonus end condition is established in the big bonus, Clear regular bonus medium flag. Here, when the regular bonus medium flag is deleted, if it is determined that the big bonus end condition is not satisfied and the big bonus medium flag is set in the RAM 112, the regular bonus medium is again set. The flag may be set in the RAM 112 and controlled to a new regular bonus as it is. In this case, when the big bonus is controlled by winning the big bonus (1) or the big bonus (2), it can be controlled to the regular bonus at the same time. When the bonus is not finished, you can immediately return to the regular bonus.

  The gaming state of the big bonus provides a small role game by winning the big bonus (1) or the big bonus (2), and further, JACIN (for example, “Bell-JAC-” based on JACIN winning in the small role game. It is also possible to provide a regular bonus among the big bonuses in the gaming state by winning a prize in an internal lottery during a small role game in “JAC”. If the regular bonus for one set is completed during the big bonus and the number of payout medals has not exceeded 465, it can be controlled again as a small role game.

  In the above embodiment, the reel control table is selected in advance based on the setting status of the winning flag, the stop position of the symbol is determined with reference to the reel control table when the reels 3L, 3C, 3R are stopped, and the stop The slot machine that stops the rotation of the reels 3L, 3C, and 3R by the table system that stops the reel at the position has been described as an example. On the other hand, based on the current symbol position when the stop condition is met and the setting status of the winning flag, pull-in control is performed so that the winning symbols are aligned, or the symbol of the winning symbol is not selected The present invention can also be applied to a slot machine that stops the rotation of the reels 3L, 3C, and 3R by a control method in which the removal control is performed so as not to be aligned.

  In the control method, when the operation of the stop buttons 12L, 12C, 12R is detected, the corresponding reels 3L, 3C, 3R are within the range of the maximum stop delay time of 190 milliseconds from the symbol displayed at that time ( It is determined whether or not there is a winning symbol having a winning flag set in a range of a total of five frames including the displayed symbol and the amount drawn. If there is a symbol with a winning flag set (determined from the symbol of the role that is given priority for derivation in duplicate wins), select the symbol for winning the winning combination and select the winning line (already stopped) When there is a reel, the winning display mode can be derived along with the symbols on the stopped reel. Otherwise, a symbol for not winning any combination is selected and derived. That is, even when the stop of the reels 3L, 3C, 3R is controlled by this control method, it can be derived by stopping the symbols within the range of the maximum stop delay time after the operation of the stop buttons 12L, 12C, 12R is detected. The display mode corresponding to the setting status of the winning flag is derived as the display result of the variable display device 2.

  In the above embodiment, the variable display device 2 includes the three reels 3L, 3C, and 3R in which a plurality of symbols are arranged in a predetermined order on the outer periphery, and the symbols are driven by rotational driving of these reels 3L, 3C, and 3R. Was variably displayed. However, it is also possible to use a device that virtually displays a symbol on a display device such as a liquid crystal display device instead of the variable display device 2 as described above.

  In the above-described embodiment, the slot machine to which medals are applied as a game medium used for setting the number of bets and giving game value associated with winning is described as an example. However, the slot machine embodying the present invention may be a slot machine (so-called parrot) to which a game ball used in a pachinko gaming machine is applied as a game medium. When game balls are used as game media, for example, one medal can correspond to five game balls, and when three bets are set in the above embodiment, 15 game balls are used. This is equivalent to setting the number of bets using.
