Description

The present invention is related to slot machines.

  Conventionally, as this type of slot machine, an internal lottery is performed to determine whether or not a winning is allowed, and when winning is won in this internal lottery, for example, a variable display device composed of a plurality of reels is won. Controls to match the combinations of symbols corresponding to winnings, and controls not to match the combinations of symbols corresponding to winnings that are not won in the internal lottery. Is common.

  As described above, as a method for controlling the combination of symbols corresponding to the winning combination according to the result of the internal lottery, for example, a symbol to be stopped at a reference position is determined at each stop operation timing. The reel table is stored in advance, and when the stop operation is performed, the reel table corresponding to the lottery result of the game is referred to, and the symbols determined on the reel table at the timing when the stop operation is performed There is a method of performing control to stop at a reference position.

  Also, if the reel table is first determined for all reels, there is a problem that the output becomes monotonous. Therefore, the reel table is selected for all reels at the start of reel rotation, and one of the reels is selected. When the stop operation is performed, the reel table is controlled with reference to the reel table of the reel. Then, when one of the reels stops, a stop position of the stopped reel for the unstopped reel, that is, a reel table corresponding to the display result of the stopped reel is selected and changed to the selected reel table, There has been proposed a slot machine in which the reel control can be changed according to the display result of the stopped reel (see, for example, Patent Document 1).

    When the subtraction result of the subtracting means exceeds a predetermined range, it may be determined that derivation of a winning display result combination of a type corresponding to data subjected to subtraction exceeding the predetermined range is allowed. .

In the specific slot machine, in addition to the initial gaming state, there are a normal gaming state and an advantageous state having a higher advantage than this, and a normal display result combination and an advantageous display result combination are derived in the initial gaming state, respectively. It is sometimes controlled. Both the normal gaming state and the advantageous state are transitions from the initial gaming state, and when the normal gaming state or the advantageous state is already controlled to the advantageous state, the normal display result combination or the advantageous display result combination is Even if the game state is derived, the game state is not controlled again to the normal game state or the advantageous state.
Control is performed depending on whether a normal display result combination or an advantageous display result combination is derived as a combination of display results derived first to a plurality of variable display units after being controlled to the initial gaming state in this way. Since there is a difference in the advantage of the gaming state to be played, the player can be interested in the combination of display results derived in the initial gaming state, and the interest of the game can be improved. In addition, by making it possible to shift from the initial gaming state to the normal gaming state and the advantageous state, the progress of the game becomes various, and the interest of the game can be improved .

  In addition, the expected value of the number of staying games in the initial gaming state is smaller than the expected value of the number of staying games in the normal gaming state, so that the game in the initial gaming state continues and the progress of the game is delayed. Disappears. Furthermore, when the expected value of the number of stay games in the initial gaming state is set to be smaller than the expected value of the number of stay games in the advantageous state, the effect becomes even greater.

Note that, for example, in the game when the derivation control means is controlled to the initial gaming state, the normal display result combination or the probability is higher than the reciprocal of the expected value of the number of staying games in the normal gaming state. by as to derive one of the advantageous results displayed combination as a combination of the display results of said plurality of variable display portions, expected expected value of the number stay the game of the initial game state is the number stays game of the normal game state It can be made smaller than the value. Here, the expected value of the number of staying games in the normal gaming state is the prescribed number of games when the normal gaming state is terminated only by the consumption of the prescribed number of games, and occurrence of a predetermined event irrespective of the number of games. In the case of being terminated only by this, it becomes the reciprocal of the probability that the predetermined event occurs. When both the specified number of games and the predetermined event are used as the end condition of the normal game state, the sum of the products of the probability of reaching each game and the puncture probability (the probability of the end of the normal game state) until the specified number of games is reached Reciprocal.

The normal display result combination and / or the advantageous display result combination may be common to the re-game display result combination . Also, the normal display result Combinations and / or the favorable results displayed combinations, small prize display result combined with the grant value for Yu technique may be one common (watermelon, bell, cherries) and. Further, when the normal display result combination or the advantageous display result combination is derived as a combination of display results of the plurality of variable display units in the normal gaming state or the advantageous state, the control is performed before the display result combination is derived. The gaming state that has been played is maintained. Furthermore, the expected value of the number of continuing games in the initial gaming state may be smaller than the expected value of the number of continuing games in the advantageous state.

The winning display result combination may include a replay display result combination (replay) that enables a next game to be performed without using a gaming value for setting the number of bets .
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 combination is permitted is higher than that in the normal game state.

  Further, the advantage for the player in the initial gaming state may be lower than the advantage for the player in the advantageous state. In this case, the player's expectation for shifting the game state from the initial game state to the advantageous state can be further enhanced.

  In addition, the difference between the advantage for the player in the initial gaming state and the advantage for the player in the normal gaming state is the advantage for the player in the normal gaming state and the advantage for the player in the advantageous state. It may be smaller than the difference in degrees.

Here, the derivation controlling means, when it is intended to derive the normal display results combination and / or the favorable results displayed in combination depending on the operation of the decision result and the derivation operation means of the predetermination means ,
Wherein the normal to derive any of the display result combination or the preferred display result combination, the normal display results by operation of the derivation operation means with high probability than the reciprocal of the continuing number of games expected value of the normal game state This means that the probability that either the combination or the advantageous display result combination can be derived is higher than the reciprocal number of the continuous game number of the normal game number.

This prevents the initial gaming state from continuing for an excessively long period of time unless the player operates the derivation operation means so as not to deduce the normal display result combination and / or the advantageous display result combination. . In any case, the slot machine according to the present invention controls the expected value of the number of continuing games in the initial gaming state to be shorter than the number of continuing games in the normal gaming state.

In the specific slot machine above,
It said predetermination means may determine whether to permit the normal display results combined with the advantageous display result combinations derived as a combination wherein the winning display result (FIG. 5, FIG. 6),
The derivation controlling means, the condition that the effect that normally allows the derivation of the display result combinations is determined as to derive the normal display result combinations, that are determined to allow the derivation of the advantageous results displayed combination it is can be made to derive the organic interest display results combining the condition.

Here, the derivation controlling means, at the time when the instruction to permit the derivation of the normal display result combinations is determined to derive the communication normally results displayed combinations regardless of the operation of the derived operating means (Bell) (FIG. 2).

Further, the derivation control means, when it is determined that the derivation of the advantageous display result combination is permitted, the advantageous display result combination (on the condition that the derivation operation means is operated by a predetermined operation ) watermelon, can be made to derive the cherry) (Figure 2).

Here, the normal display result combination to be controlled from the initial gaming state to the normal gaming state with a low advantage is derived only by the determination of the pre-determining means, but the game is changed from the initial gaming state to the advantageous state with a high advantage. In the advantageous display result combination for controlling the state, in addition to the determination by the predetermining means, a condition that the player must operate the derivation operating means by a predetermined operation is added. In this way, by causing the player to intervene in the control to the advantageous state with a high degree of advantage, it is possible to make a difference in the profits obtained by the player according to the skill and further improve the interest of the game. .

In this case, the expected value of the number of continuing games in the initial gaming state may be smaller than the reciprocal of the probability that it is determined that derivation of any one of the normal display result combinations is permitted. The expected value of the number of continuing games in the initial gaming state may be smaller than the reciprocal of the probability that it is determined that the advantageous display result combination is allowed to be derived. The expected value of the number of continuing games in the initial gaming state is smaller than any of the reciprocals of the total probabilities determined to permit the derivation of either the normal display result combination or the re-game display result combination. can do.

The probability that the derivation of the normal display result combination is determined so that the expected value of the number of continuing games in the initial gaming state is as described above, and the determination that the derivation of the advantageous display result combination is permitted are determined. It is possible to control the gaming state to the normal gaming state or the advantageous state by ending the initial gaming state early.

In the specific slot machine above ,
The presentation control means, when said the initial game state is a gaming state is controlled, it is assumed that further comprises an initial game state informing means (step S1229) to notify the subject that is controlled to initial game state Can do.

By notifying the player that it is controlled to the initial gaming state in this way, it is no longer that the initial gaming state has been controlled to the normal gaming state or the advantageous state without knowing the player, When there is a possibility of being controlled from the initial gaming state to the normal gaming state or the advantageous state, it becomes possible to attract the player's interest in the combination of the display results of the plurality of variable display units.

In the specific slot machine above,
The gaming state control means is configured such that when a predetermined special display result combination (regular bonus, big bonus (1), big bonus (2)) is derived as a combination of display results of the plurality of variable display units , A special game that controls the gaming state to a special gaming state (regular bonus, big bonus) that is advantageous to a player different from the advantageous state, and terminates the special gaming state when a predetermined special termination condition is satisfied. State control means (steps S 10 08, S 10 10, S 10 12) may be further included. In this case,
The initial gaming state control means may control the gaming state to the initial gaming state when the special gaming state is ended as the initialization condition (steps S1106 and S1116).

  In this way, after the special gaming state is finished, it is assumed that the initial gaming state is controlled, so that the player's interest can be prevented from being lost even in the game after the special gaming state is finished, Furthermore, the interest of the game can be improved.

In this case,
The special game state control means, a first special game state of the special game state when the first special display result combinations of the special display result combinations (regular bonus) is derived (regular bonus) first special game state control means for controlling the gaming state (step S1012) and, second special display result combination is specially display result combination of first a special display result different combinations (big bonus (1), When the big bonus (2)) is derived, the first special gaming state is controlled to the second special gaming state (big bonus), which is a special gaming state having a different advantage for the player. 2 special gaming state control means (steps S1008, S1010),
The initial gaming state control means controls the gaming state to a first initial gaming state (initial gaming state A) of the initial gaming states when the first special gaming state is ended as the initialization condition, The ratio of the probability that the derivation control means derives the advantageous display result combination with respect to the probability that the derivation control means derives the normal display result combination when the second special gaming state ends as an initialization condition is greater than the first initial gaming state. The gaming state may be controlled to the second initial gaming state (initial gaming state B) which is a high initial gaming state.

Thus, after the second special gaming state is completed, the advantageous display result combination is easily derived, and the second initial gaming state is easily controlled to the advantageous state, so that the special gaming state is simply controlled. Since there is a difference not only in the difference in the advantage during the game, but also in the advantage after the special gaming state is ended, the combination of the first special display result and the second special display result combination as the special display result combination The player's interest in which one is derived is further increased, which can improve the interest of the game.

In the specific slot machine above,
The normal game state control means ends the normal game state when a predetermined normal end condition (digestion of 1000 games) is satisfied,
The initial gaming state control means may control the gaming state to the initial gaming state when the normal gaming state is ended as the initialization condition (step S1109).

The advantageous state control means may end the advantageous state when a predetermined advantageous end condition (digestion of 100 games in the second RT based on watermelon) is satisfied,
The initial gaming state control means may control the gaming state to the initial gaming state when the advantageous state is ended as the initialization condition (step S1111).

  Here, when there are the first initial gaming state and the second initial gaming state as the initial gaming state, the initial gaming state control means, when the normal gaming state ends, the first gaming state control means The gaming state can be controlled to the initial gaming state. Even when the advantageous state ends, the gaming state can be controlled to the first initial gaming state.

As described above, even if the gaming state is once controlled from the initial gaming state to the normal gaming state, the normal gaming state is terminated when the predetermined normal termination condition is satisfied, and the initial gaming state is controlled again. Therefore, depending on which of the normal display result combination and the advantageous display result combination is derived first, the player can expect to be controlled to the advantageous state. As a result, once the player has been controlled to the normal gaming state, the player's expectation can be prevented from being completely lost. Also, even if the initial gaming state is once controlled to the advantageous state and then the advantageous state is terminated by the establishment of a predetermined advantageous ending condition and the initial gaming state is controlled again, the advantageous display result combination is first There is also a possibility that it will be derived and be controlled again in an advantageous state. For this reason, a player's expectation is not lost.

Even if the initial gaming state is once controlled to the normal gaming state or the advantageous state, the gaming state is often transferred if the gaming state may return to the initial gaming state again without continuing. Diversity in the progress of the game will improve the interest of the game. Note that the second initial gaming state is associated with the second special gaming state by setting the initial gaming state controlled after the normal gaming state or the advantageous state is ended to the first initial gaming state that is difficult to be controlled to the advantageous state. As a special initial gaming state to be performed, the player's expectation for deriving the second special display result combination can be further enhanced.

  Even if the normal end condition (and the advantageous end condition) is satisfied by digesting a predetermined number of games, the game state is controlled to the normal game state (and the advantageous state). It may be established when the winning lottery is held.

  In such a case, when the normal gaming state (and the advantageous state) is controlled again to the initial gaming state, the initial gaming state is controlled even if the initial gaming state notification means is provided. It can be assumed that there is no notification. As a result, for example, even if the normal gaming state continues, the player can expect the possibility of being controlled to the advantageous state because it is controlled to the initial gaming state, and the interest of the game is further improved Can be made. In particular, when the initial game state and the normal game state have the same advantage for the player, this effect is increased.

In the specific slot machine above ,
The game control means has different probabilities that the predetermination means determines that the winning display result combination is allowed to be derived based on the operation of predetermined setting operation means (setting key switch 92, setting switch 91). Permissible stage setting means (steps S201 to S211) for selecting and setting one of the permissible stages from among a plurality of types of permissible stages (setting values) may be further provided. In this case,
The initial gaming state control means, when the allowable stage is set by the allowable stage setting means as the initialization condition, the gaming state to the initial gaming state regardless of the gaming state controlled before the setting Can be controlled (step S209).

  When the initial gaming state includes the first initial gaming state and the second initial gaming state, the initial gaming state control means is configured to perform the first initial gaming state when the allowable stage is set. The gaming state can be controlled to the gaming state.

In this way, after setting the allowable stage newly, it is assumed that it is controlled to the initial gaming state, so that the player is given a chance to be controlled to the normal gaming state or the advantageous state. Can do. Note that the second initial gaming state is associated with the second special gaming state by setting the initial gaming state controlled after newly setting the allowable stage as the first initial gaming state that is difficult to control to the advantageous state. As an initial gaming state, the player's expectation for deriving the second special display result combination can be further enhanced.

  Further, even when the initial gaming state notifying means is provided, when the initial gaming state is controlled by the setting of the allowable stage, it is not possible to notify that the initial gaming state is in effect.

  If the initial stage gaming state is not notified by setting the allowable stage, for example, even if the allowable stage is changed at the opening of the game store, the player cannot determine this. For this reason, the change of the allowable stage is not perceived by the player, and the fairness of the game can be achieved.

In the specific slot machine above,
The pre-determining means includes a special display result combination (regular bonus, big bonus (1), big bonus (2) with a transition to a special gaming state advantageous to the player different from the advantageous state as the winning display result combination. )) And whether to allow the derivation of a replay display result combination (replay) that allows the next game to be played without using the gaming value in setting the bet amount,
The advantageous state control means controls the gaming state to a re-gaming high probability state (second RT) in which the probability of determining that the derivation of the re-game display result combination is allowed is higher than the normal gaming state as the advantageous state. You may do. In this case,
The gaming state control means, until said special display result該特another display result combinations based on the decision to permit the derivation of the combination is derived, to carry over the decision to permit the derivation of該特based display results combination A special decision carryover means (step S1124) ;
The effect control means is configured to continue for a continuous effect period longer than one game when a display result combination other than the winning display result combination is derived when the replay high probability state is controlled. It further includes continuous production execution means (steps S1207 (YES) → S1208 (YES) → S1209, S1210, S1222) for executing the production during the continuous production period .
The gaming state control means controls the gaming state to the special gaming state (regular bonus, big bonus) when the special display result combination is derived as a combination of display results of the plurality of variable display units. It further includes state control means (steps S1008, S1010, S1012),
The derivation controlling means, from該特based display results combination when that which allows the derivation of the replay display results combined in a state in which decision to permit the special display result combination derivation is carried over is determined can be assumed to be preferentially該再game display result combinations including replay priority deriving means for deriving as a combination of the display results of said plurality of variable display portions.

Since the replay high probability state is applied as the advantageous state in this way, the replay display result combination is derived in many games while being controlled to the advantageous state. Here, assuming that the derivation of the special display result combination may not be determined in the same game as the derivation of the re-game display result combination may be determined as a combination of display results of a plurality of variable display units. When the display result combination is not derived, it may be determined that the derivation of the special display result combination is permitted in the game, and the player's expectation can be enhanced. In addition, it is possible to increase the player's expectation that it is determined that the derivation of the special display result combination is permitted by the continuous production started at this time, and the interest of the game can be improved. Here, in the advantageous state, even if the decision to allow the derivation of the special display result combination is carried over, the replay display result combination that is determined to allow the derivation with high probability is derived with the highest priority. The continuous performance can be continued until the continuous performance period ends without deriving as many special display result combinations as possible for shifting the special game state. Also, if the continuous presentation is being performed, it means that a possibility that can be derived a special display results combination when the instruction to permit the derivation of replay display result combination is not determined is increased, the game Can increase the expectation of the person.

Here, the continuous production execution means continuously executes the continuous production for the continuous production period, and notifies information indicating whether or not it is determined to permit the derivation of the special display result combination. This can be done (step S1226).
Further, the continuous production execution means is also determined to permit the derivation of the special display result combination when the prior determination means permits the derivation of the special display result combination , or to permit the derivation of any kind of winning display result combination. When there is not, the continuous production can be executed.

In this way, it is possible to increase the player's interest in the continuous performance by performing the continuous performance and notifying the information indicating whether it is determined to allow the derivation of the special display result combination. The interest of the game can be improved. In addition, since the game before the information indicating whether or not it is decided to allow the derivation of the special display result combination can be obtained, the player's sense of expectation can be obtained by continuous production. Can improve the interest of

In the specific slot machine above,
In the normal gaming state, the expected value of the number of game value payouts calculated based on the probability that the pre-determining means determines that the derivation of the winning display result combination is permitted is the setting of the bet number. A gaming state that is smaller than the number of gaming values used
The advantageous state may be a gaming state in which, when the advantageous display result combination is derived, an expected value of the value value payout rate is larger than the number of gaming values used for setting the betting amount. Good.

In this case, the number of gaming values owned by the player decreases when controlled from the initial gaming state to the normal gaming state , but the number of gaming values owned by the player increases when controlled to the advantageous state. It will follow. This difference in the player's profits depending on whether it is controlled from the initial gaming state to the normal gaming state or to the advantageous state, the first normal display result combination after being controlled to the initial gaming state It is possible to increase the player's interest in whether or not an advantageous display result combination is derived.

In the specific slot machine above,
The normal game state control means ends the normal game state when a predetermined normal end condition (digestion of 1000 games) is satisfied,
The advantageous state control means may terminate the advantageous state when the number of digested games after being controlled to the advantageous state reaches a predetermined prescribed number of games (100 games). here,
The gaming state control means derives a specific display result combination (predetermined special combination ) different from the re-game display result combination as the winning display result combination when being controlled in the normal gaming state or the advantageous state. It is further possible to further include specific game state control means for controlling the game state to a specific game state (predetermined game state) advantageous to the player different from the advantageous state. In this case,
The pre-determining means may determine that the derivation of the specific display result combination is permitted with a probability lower than the reciprocal (1/100) of the prescribed game number.
When the initial game state control means determines that the derivation of the specific display result combination is permitted by the prior determination means (or the specific display result combination as a combination of display results of the plurality of variable display portions ) When the specific gaming state ends as the initialization condition, the gaming state can be controlled to the initial gaming state.

As described above, when it is determined that the derivation of the specific display result combination is permitted (or when the specific game state based on the derivation of the specific display result combination ends), the initial game state is controlled. As a result , the normal game state or the advantageous state is controlled depending on which of the normal display result combination or the advantageous display result combination is derived first. The interest of the game can be improved. On the other hand, the probability that it is determined that the derivation of the specific display result combination is permitted is lower than the reciprocal number of the prescribed number of games until the advantageous state is terminated, and thus is once controlled to the advantageous state having a high advantage. After that, it is possible to reduce the number of cases where the game is terminated without digesting the prescribed number of games, and the player's expectation is not lost.

In the specific slot machine above,
The advantageous state control means may terminate the advantageous state when the number of digested games after being controlled to the advantageous state reaches a predetermined prescribed number of games (100 games). here,
The gaming state control means derives a specific display result combination (predetermined special combination ) different from the re-game display result combination as the winning display result combination when being controlled in the normal gaming state or the advantageous state. It is further possible to further include specific game state control means for controlling the game state to a specific game state (predetermined game state) advantageous to the player different from the advantageous state. In this case,
When the initial gaming state control means determines that the derivation of the specific display result combination is permitted by the predetermining means in the normal gaming state as the initialization condition (or the plurality of variable display units to) when the specific display results combination as a combination of the display result is derived, the when a specific game state is completed as the initialization condition, it can be made to control the gaming state to the initial game state.

When it is determined that the derivation of the specific display result combination is permitted as described above (or when the specific game state based on the derivation of the specific display result combination is ended), the normal game state is controlled. Even so, by assuming that the gaming state is controlled to the initial gaming state, it is possible to further increase the player's expectation that it is determined by the predetermining means that the derivation of the specific display result combination is permitted. And can further enhance the fun of the game.

In the above slot machine,
The plurality of variable display sections rotate 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). Thus, the display may be variable .

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 obtained at the time when a derivation operation unit corresponding to the variable display unit is operated. the plurality of control patterns that uniquely identify the display results to be derived for deriving operation at step number is the number of steps of the stepping motor: (FIG. 9 stop control table), corresponding to the determined result of said pre-determining means Including a control pattern selection unit for all fluctuations for uniquely selecting a control pattern to be performed (step S705),
In both the situations not yet displayed result is derived also of the plurality of variable display portions, when the derivation operation means corresponding to the variable display portion which is not yet displayed result is derived is operated, the total variation during control for the variable display unit in the uniquely selected control pattern corresponding to the determination result of the pre-determined unit by the pattern selecting means, uniquely identified for the derivation operation when the number of steps of the operation point of the conductor out operation means Control to derive the display result to be performed as the display result in the variable display unit can be performed (step S715).

In this case, the step of the stepping motor at the time when the derivation operation means is operated for the variable display unit for which the display result has not yet been derived in the situation where the display result has not yet been derived for all of the plurality of variable display units. a plurality of control patterns that uniquely identify the display results to be derived for several, the game of the selected uniquely control pattern corresponding to the determined results of the pre-determining means, the display result on the variable display unit applicable control of deriving 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, and each variable display unit It is not complicating the control of deriving the display results.

The specific derivation control means includes
In a situation where a display result has already been derived on the first variable display unit and a display result has not been derived on the second variable display unit, the deriving operation means corresponding to the second variable display unit is operated. and with respect to the derivation operation when the number of steps of the time, a plurality of control patterns that uniquely identify the possible display results derived in the range of conductor out operation when the number of steps until a predetermined number of steps away (Figure 9: stop control table) from one to select uniquely a control pattern corresponding to the already deriving step number is a number of steps when the corresponding derivation operation means is operated in the decision results and said first variable display portion of the pre-determination means Part variation control pattern selection means (step S705),
In a situation where a display result has already been derived on the first variable display unit and a display result has not been derived on the second variable display unit, the deriving operation means corresponding to the second variable display unit is operated. when the, for the second variable display unit in the uniquely selected control pattern corresponding to the determination result and the already derivation step number of the predetermination means by said portion varies during the control pattern selecting means, wherein the display result uniquely identified for the derivation operation when the number of steps of the point of operation deriving operating means, can be made to perform control to derive a display result in the second display portion (step S715) .

Alternatively, the specific derivation control means includes
In a situation where a display result has already been derived on the first variable display unit and a display result has not been derived on the second variable display unit, the deriving operation means corresponding to the second variable display unit is operated. and with respect to the derivation operation when the number of steps of the time, a plurality of control patterns that uniquely identify the possible display results derived in the range of conductor out operation when the number of steps until a predetermined number of steps away (Figure 9: stop control table) from comprises said predetermination means determining results and the first portion varies during the control pattern selecting means for uniquely selecting a control pattern corresponding to the display result in the variable display unit (step S715),
In a situation where a display result has already been derived on the first variable display unit and a display result has not been derived on the second variable display unit, the deriving operation means corresponding to the second variable display unit is operated. when the, selected uniquely corresponding to the display result in the decision result and the first variable display portion of the pre-determining means for said second display portion by said portion varies during the control pattern selecting means in the control pattern, the display results to identify uniquely to the derivation operation when the number of steps of the operation point of the conductor output operating means, also be made for controlling to derive a display result in the second display portion Yes (step S715).

In the case of these has already been derived displays results on the first display portion, in a situation that is not yet displayed result is derived in the second display portion, a second display portion, a plurality of control patterns that uniquely identify the display results to be derived for the number of steps of the stepping motor at the time the derivation operation means is operated, the determination of the pre-determination means results and display binding of the first variable display unit fruit (or number of steps when the corresponding derivation operation means is operated in the first variable display portion) is selected uniquely corresponding control pattern, the control to derive the displayed results on the second display portion Done. That predetermination means determination result and displaying the results of the first variable display unit (or, the number of steps when deriving operating means corresponding to the first variable display portion is operated) to control applied for There is only one pattern. Therefore, further it is not necessary to select one of the control patterns from a plurality of control patterns, is not to complicate the control of deriving the display result of the variable display unit.

In the specific slot machine above ,
The game control means is configured to determine with a higher probability than the game in the normal game state that the pre-decision means allows the derivation of the small role display result combination when a predetermined special condition is satisfied. Special game control means (steps S703 and S1012) for controlling the game (regular bonus) for a predetermined period may be provided.

Here, the game control means further includes special game determination means (step S702) 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) S703).

In this case, the same processing is performed when the special game is first controlled after the special condition is established , or when the special game is once ended and the special state is not ended yet, and the special game is controlled again. Will do.

  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 specific slot machine above,
The pre-determining means determines whether to permit derivation of both the special display result combination and the small role display result combination in one game (FIGS. 5B and 5C: regular bonus + Cherry, big bonus (1) + cherry, big bonus (2) + cherry).

Thus special display result may be that it is determined to allow the combination of the small win display results of both combinations derived, small prize display result combination is derived as a combination of the display results of a plurality of variable display portions This makes it possible for the player to expect that the derivation of the special display result combination is permitted, thereby improving the interest of the game.

In the above slot machine ,
The game control means includes
Based on the operation of predetermined setting operation means (setting key switch 92, setting switch 91), a plurality of types of allowable stages with different probabilities that it is determined by the prior determination means that the derivation of the winning display result combination is permitted ( An allowable stage setting means (steps S201 to S210) for selecting and setting one of the allowable stages from the set values);
Data storage means (RAM 112) for storing data for controlling the progress of the game including data indicating the allowable stage set by the allowable stage setting means in a readable and writable manner;
Stored data determination means (steps S105 and S106) for determining whether or not the data stored in the data storage means is normal;
Disabling means (step S106 (NO), step S301) for disabling the progress of the game when the stored data determination means determines that the data stored in the data storage means is not normal;
In a state where the progress of the game is disabled by the disabling means, the progress of the game is performed on the condition that the allowable stage is newly set by the allowable stage setting means based on the operation of the setting operation means. It is possible to further include disabling canceling means (step S111, FIG. 11) for canceling the disabled state and allowing the game to proceed.

Conventionally, when the data stored in the data storage means (RAM) in the slot machine is broken, the game cannot be progressed. The data in the data storage means is initialized by a predetermined reset operation. It was released above and the game progress was resumed. Here, when the data in the data storage means is initialized by the reset operation, there is a default permissible stage (usually the permissible stage with the lowest probability of being determined to permit the derivation of the winning display result combination ). It was supposed to be selected automatically. For this reason, the pre-determining means may not be determined with the probability that the amusement store has intended, and it is disadvantageous to the player especially when it is automatically selected at the allowable stage with the lowest probability. There was a problem that would become larger.

  On the other hand, when the data stored in the data storage means is not normal, the game cannot be progressed because the proper game cannot be progressed. It is necessary to initialize the data stored in the data storage means in order to cancel the state where the game cannot be progressed here. In this case, the data indicating the allowable stage is also initialized. End up. However, in the slot machine, the state in which the game cannot be progressed based on the data in the data storage means being normal is canceled unless a new allowable stage is set based on the operation of the setting operation means. There is nothing. For this reason, since it is ensured that the game is played based on the newly set allowable stage, the fairness of the game can be achieved.

In this case,
The pre-determining unit reads data indicating an allowable level stored in the data storage unit when determining whether to permit the derivation of the winning display result combination , and the read allowable level Permissible stage data determining means (steps S708 and S709) for determining whether the data to be shown is appropriate data indicating the allowable stage that can be set by the allowable stage setting means may be included. here,
The disabling means can disable the progress of the game even when the allowable stage data determination means determines that the data indicating the allowable stage read from the data storage means is not appropriate data ( Step S709 (NO), step S301).

  Here, even when the determination is made by the prior determination means, the allowable stage stored in the data storage means is read to determine whether the allowable stage is appropriate. If the allowable stage is not appropriate, the game cannot be progressed properly because the game cannot be progressed properly. Here, in a state where the progress of the game is disabled based on the fact that the allowable stage stored in the data storage means is not within an appropriate range, a new allowable stage must be set based on the operation of the setting operation means. It will not be released. For this reason, since it is ensured that the game is played based on the newly set allowable stage, the fairness of the game can be achieved.

  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. the setting key switch 92 to enable operation, are respectively connected to the main switch 94 to perform the second reset switch 93 and oN / OFF switching of the power supply, to reset the internal state (RAM 112), the detection signal of these switches 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 set. 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. Then, a transition is made to a state in which the game can proceed in the initial 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-BAR-BAR” is aligned on any of the winning lines (five) in the initial gaming state or RT (first RT or second RT described later). When the regular bonus is won, the gaming state shifts from the initial 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. After the regular bonus (except when provided during the big bonus), the game is controlled to the initial gaming state. Further, while the game state is in the regular bonus, a 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 the combination of “7-7-7” is arranged in any of the winning lines (five) in the initial gaming state or RT. The big bonus (2) is awarded when the combination of “BAR-7-7” is aligned on any of the winning lines (five) in the initial gaming state or RT. When the big bonus (1) or the big bonus (2) is 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, all operations of the player are invalid except for the payment of credits, and the game is controlled to a freeze state in which the game cannot be progressed for a certain period of time. In addition, after the big bonus ends, the game state is controlled to the initial gaming state.

  Even if the regular bonus, big bonus (1) or big bonus (2) is won in the internal lottery to be described later, both “7” and “BAR” are within 5 frames for all reels 3L, 3C, 3R. Since they are not arranged at intervals, if the stop buttons 12L, 12C, and 12R are not operated according to an appropriate operation procedure that makes it possible to win the winning combinations, the winning combinations will not be won. Of course, if you don't win any of these roles without being operated in the proper operating procedure, you will be able to derive a chance that you can derive when you win or not win these roles ( From a point of view, there may be cases where a loss) is derived.

  Watermelons are also won in regular bonuses (including those offered during a big bonus) when the combination of “Bell-Watermelon-Bell” is aligned on one winning line, and 15 medals are paid out. . Since the “watermelons” are not arranged at intervals of 5 frames or less for the reels 3L, 3C, and 3R, even if the watermelon is won in the internal lottery described later, the operation timing of the stop buttons 12L, 12C, and 12R May not win a watermelon. In addition, after winning a watermelon in the initial gaming state, the gaming state is controlled to a second RT described later for 100 games.

  Bell is awarded when any combination of “Bell-Bell-Bell” is aligned on any winning line (5 or 1) in any gaming state, and 9 medals are paid out. Since all of the reels 3L, 3C, and 3R have “bells” arranged at intervals of 5 frames or less, the operation timing of the stop buttons 12L, 12C, and 12R if the bell is won in the internal lottery described later. Regardless, you can win the bell. Further, after winning the bell in the initial gaming state, the gaming state is controlled to a first RT described later for 1000 games.

  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. When “Cherry” is stopped at the upper or lower stage of the left reel 3L in a gaming state other than the regular bonus, a total of four medals are paid out since the derivation is made on two pay lines. Since the “bells” are not arranged at intervals of 5 frames or less on the left reel 3L, even if the watermelon is won in the internal lottery described later, depending on the operation timing of the stop buttons 12L, 12C, 12R, May not win. In addition, after winning the cherry in the initial gaming state, the gaming state is controlled to the second RT described later until the next regular bonus, big bonus (1) or big bonus (2) is won.

  The game state is controlled by the second RT not only when winning a watermelon or cherry but also when winning a regular bonus, a big bonus (1) or a big bonus (2). If the regular bonus, the big bonus (1), or the big bonus (2) is won while the gaming state is already controlled by the second RT, the second RT continues until winning of these roles. The RAM 112 of the game control board 101 is provided with a first RT counter and a second RT counter that are decremented each time one game is consumed when the gaming state is the first RT and the second RT, respectively. However, the initial value of 102 is set in the second RT counter as a result of winning a cherry prize, regular bonus, big bonus (1) or big bonus (2). Regular bonus, big bonus (1) or big bonus (2) Will not be deducted until the winning of Details of the first RT or the second RT will be described later.

  Replay is awarded when the combination of “Replay-Replay-Replay” is aligned on any of the winning lines (5) in the initial gaming state or RT. Since the “replays” for the reels 3L, 3C, and 3R are all arranged at intervals of 5 frames or less, when a replay is won in an internal lottery that will be described later, a replay winning is always made. When you win a replay, you won't be paid out medals, but you can start the next game without setting the number of bets again, so the number of bets that you don't need to set in the next game (the regular bonus won't be replayed for 3) This is substantially the same as paying out three medals corresponding to.

  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. When in the initial gaming state, regular bonus + cherry, regular bonus, big bonus (1) + cherry, big bonus (1), big bonus (2) + cherry, big bonus (2), watermelon bell, cherry, replay (initial) ) Are sequentially read out as a target combination of the internal lottery. When the gaming state is the first RT (shown as RT1 in the figure) and the second RT (shown as RT2 in the figure), instead of the replay (initial) in the initial gaming state, replay (RT1) and replay (RT2), respectively. Are sequentially read out as the target combination of the internal lottery. Replay (initial), replay (RT1), and replay (RT2) have different winning probabilities because the storage areas for the number of determination values described later are different, but the other points are common.

  In the internal lottery, the number of determination values determined for the internal lottery target combination is sequentially added to the internal lottery random number, and when the addition result overflows, it is determined that the winning combination is won. 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. The number of determination values may be 256 or more, and cannot be stored for one word. Therefore, each determination value is registered using a storage area for two words. The number of determination values corresponding to the number of bets of each lottery object combination is common regardless of the set value, and is 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 + Cherry, Big Bonus (1) + Cherry, Big Bonus (2) + Cherry are small lottery games, initial gaming state, and a combination subject to internal lottery in the first RT or second RT. 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 roles that are subject to internal lottery in the initial gaming state, the first RT or the second RT. 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.

  Watermelons, bells and cherries are roles that are subject to internal lottery in any gaming state. For the watermelon and the bell, the common flag is 1, and the storage address of the common determination value number is registered irrespective of the set value corresponding to the number of bets. For cherry, the common flag is 0, and the storage address for the number of determination values is registered individually according to the set value corresponding to the number of bets.

  Replay (initial) is a role that is subject to internal lottery only in the initial gaming state. Replay (RT1) is a role that is subject to internal lottery only in the first RT. Replay (RT2) is a role that is subject to internal lottery only in the second RT. 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.

  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 + cherry and the set value is 1-6. The address ADD + 14 is an address that is referred to when the target combination of the internal lottery is big bonus (1) + cherry and the set value is 1-6. The address ADD + 28 is an address that is referred to when the target combination of the internal lottery is big bonus (2) + cherry 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 + cherry 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 when the case of overlapping winning with the cherry is included.

  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 when the bet number is 3, that is, in the gaming state other than the regular bonus, the target combination of the internal lottery is a watermelon and the set value is 1-6. The address ADD + 44 is an address that is referenced when the number of bets is 1, that is, when the target character of the internal lottery is a watermelon and the set value is 1 to 6 in the regular bonus (including the case where it is provided during the big bonus) . Since the same determination value number 454 is registered in the address ADD + 42 and the address ADD + 44, the winning probability of the watermelon does not differ depending on the gaming state.

  The address ADD + 46 is an address that is referred to when the number of bets is 3, that is, in a gaming state other than the regular bonus, the target combination of the internal lottery is a bell and the set value is 1-6. The address ADD + 48 is an address that is referenced when the number of bets is 1, that is, in a regular bonus (including a case where the bonus is provided during a big bonus), the target part of the internal lottery is a bell and the set value is 1-6. . Since the number of determination values registered in the address ADD + 46 is larger than the number of determination values registered in the address ADD + 48, the winning probability of the bell in the regular bonus is higher than the winning probability of the bell in other gaming states.

  Addresses ADD + 50, ADD + 52, ADD + 54, ADD + 56, ADD + 58, and ADD + 60 are addresses that are referenced when the number of bets is 3, that is, in a game state other than the regular bonus, the internal lottery target is a cherry and the set value is 1-6 It is. Addresses ADD + 62, ADD + 64, ADD + 66, ADD + 68, ADD + 70, and ADD + 72 have a bet number of 1, that is, in a regular bonus (including the case where the bonus is provided during a big bonus), the target part of the internal lottery is cherry and the set value is 1 This address is referred to when 6. The number of determination values registered in the addresses ADD + 62, ADD + 64, ADD + 66, ADD + 68, ADD + 70, and ADD + 72 is 60 larger than the number of determination values registered in the addresses ADD + 50, ADD + 52, ADD + 54, ADD + 56, ADD + 58, and ADD + 60, respectively. In game states other than the regular bonus, the cherries are subject to lottery overlapping with the regular bonus, the big bonus (1) and the big bonus (2), and the total number of these judgment values is 60. The probability of winning a cherry does not vary depending on the gaming state.

  The address ADD + 74 is an address that is referred to when the target combination of the internal lottery is replay (initial) and the set value is 1-6. The address ADD + 76 is an address that is referred to when the target part of the internal lottery is replay (RT1) and the set value is 1-6. The address ADD + 78 is an address that is referred to when the target part of the internal lottery is replay (RT2) and the set value is 1-6.

  By performing the internal lottery with such a number of determination values, in the initial gaming state, the medal payout rate is smaller than 1 (that is, the internal lottery wins the number of medals inserted for setting the bet number). The smaller the number of medals that will be paid out for a small role). In the first RT, although the replay winning probability is higher than the initial gaming state, the number of replay judgment values is only 1 different from the initial gaming state, so the medal payout rate is almost the same as the initial gaming state and smaller than 1. It has become a thing. In the second RT, the replay winning probability is extremely higher than in the initial gaming state, so that the medal payout rate is increased and is larger than 1 (that is, the internal number of medals to be inserted for setting the number of bets). The number of medals that will be paid out for the small role won in the lottery is larger).

  Further, it goes without saying that the medal payout rate in the big bonus and the regular bonus exceeds 1, and is higher than the medal payout rate in the second RT. That is, the big bonus or the regular bonus is the most advantageous gaming state for the player, and the second RT is the next advantageous gaming state. 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.

  Furthermore, considering the winning probability of watermelon, bell, and cherry in the initial gaming state, the winning probability of the bell that controls the gaming state in the first RT is extremely higher than the winning probability of watermelon and cherry that controls the gaming state in the second RT. high. Also, considering the winning probabilities of watermelon, bell and cherry in the initial gaming state, the number of games from the initial gaming state to the first RT or the second RT is only a few games. The winning probability of the regular bonus, the big bonus (1), and the big bonus (2) is very low compared to the winning probability of watermelon, bell, and cherry. Therefore, in the slot machine 1 according to this embodiment, the number of games executed in the state controlled by the first RT is the largest, and the first RT is the normal gaming state in the slot machine 1.

  Note that the expected value of the number of staying games in the initial gaming state is approximately 4 games, which is the reciprocal of the probability of winning a certain role in the initial gaming state, assuming that the winning combination is not missed. The expected value of the number of stay games in the first RT is 1000 games if only 1000 games are completed. However, when the regular bonus, the big bonus (1) or the big bonus (2) is won, 1RT will end. In this case, the expected value of the number of staying games can be calculated by the reciprocal of the sum of the product of the probability of reaching the 1, 2,..., 1000th game and the probability of ending the normal gaming state in each game. .

  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, in correspondence with the area number, the timing (reel reference) corresponding to the area number is positioned at the stop reference position (in this embodiment, the lower symbol area). The number of frames to be drawn when the operation of the stop buttons 12L, 12C, 12R is detected at the timing at which the number of steps from the 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 it is stopped 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 that is the stop position ahead of the number of frames to be drawn 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.

  In addition, 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 the previous game (Big Bonus (1) + Cherry, 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 within the draw range of up to 4 frames can be aligned and stopped on the winning line, the control is performed to align and stop them. 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 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 as much as possible 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. “Replay” which is a symbol constituting the re-gamer is arranged at an interval of 5 frames or less for each 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 the type of winning generated according to the display result of the variable display device 2 and the number of medals to be paid out with the winning. The display result is derived to the variable display device 2 and the winning determination is made. Sent when done. The gaming state command indicates a gaming state applied in the next game, and is transmitted at the end of one game.

  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 the effects executed by the control of the CPU 121, a continuous effect that is continuously performed for three game periods, a bonus winning effect that is performed when a regular bonus, a big bonus (1), or a big bonus (2) is won, and a big When the game is started in the initial gaming state, the freezing effect that is performed when the game is in the frozen state after the end of the bonus, the chance effect that is performed when a chance eye is derived as the display result of the variable display device 2 (In fact, there is an initial notification performed at the end of the previous game).

  The freeze effect is an effect in which the image display on the liquid crystal display 4, the sound output from the speakers 7L, 7R, and 7U, and the lighting of various lamps are all stopped for a certain period. This is performed in a period in which the substrate 101 is controlled to be in a frozen state. The CPU 121 of the effect control board 102 can recognize that it is controlled in the freeze state with reference to two game state commands. That is, if the gaming state command received in the previous game indicates the big bonus and the state command received in the current game indicates the initial gaming state, the big bonus ends in the current game and is controlled to the frozen state. I understand that. For this determination, the RAM 122 is provided with an area for storing the past two gaming states.

  In addition, the continuous performance starts with a game that has not won any combination in the second RT, and ends after continuing for three game periods. Whether the second RT to start the continuous performance is the second RT controlled by winning a watermelon or cherry, or the second RT controlled by winning a regular bonus, a big bonus (1) or a big bonus (2) It doesn't matter. The RAM 122 has an area for storing the winning status for the past two times.

  Continuous production is performed regardless of whether the regular bonus, the big bonus (1) or the big bonus (2) is won (including carryover) or not. If it is lost in the internal lottery at the time, it will be done with a probability of 100%, but if the winning flag for these roles is not set, it will not necessarily be done even if it is lost in the internal lottery, so the bonus notice effect It has the character as.

  In order to control the execution of the continuous effect, the RAM 122 is provided with an area for storing a continuous counter for counting the number of remaining games of the continuous effect. If the regular bonus, the big bonus (1), or the big bonus (2) is won at the end of the continuous performance, a bonus confirmation notification that informs the player that the winning combination has been won. Is done.

  In addition, the chance effect is performed when the chance is derived in the variable display device 2, but from the viewpoint of winning, the chance is lost, so whether the chance is derived even if the winning information command is referred to. The CPU 121 of the effect control board 102 cannot recognize how. The display mode derived to the variable display device 2 is determined based on the reel rotation command and the reel stop command.

  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.

  The initial notification is performed when the received winning situation notification command indicates that the game is in the initial gaming state. The bonus winning effect is performed when the received winning information command indicates winning of a regular bonus, a big bonus (1), or a big bonus (2). At this time, the continuous production being executed is forcibly terminated, and if a bonus winning notification is performed, this is also terminated.

  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. 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 lever 11 (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 lever 11 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). Further, the regular bonus medium flag and the big bonus medium flag are erased, and the values of the first RT counter and the second RT counter are initialized to 0, and the gaming state in the game after the setting change process is set to the initial gaming state (step S209). ).

  Thereafter, the process waits until the setting key switch 92 is turned off (step S210). If it is determined in step S210 that the setting key switch 92 has been turned off, the setting changing flag set in step S201 is cleared (step S211). Then, when returning to the flowchart of FIG. 10, the game progresses in the initial game state 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. Below, a description will be given to each game in the slot machine 1. 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, first, an initial process including a process of clearing a predetermined area of the RAM 112 is 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). If the player has won a replay in the previous game, the same number of bets as in the previous game (3 in this embodiment) is automatically set by the replay game flag (the replay game flag is erased at this stage). ). Details of the BET process will be described later.

  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 a winning flag that does not carry over) 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 BET process in step S402 will be described in detail. 14 and 15 are flowcharts illustrating in detail the BET process executed by the CPU 111 in step S402. In the BET process, the value of the BET counter in which the value of the bet number is stored in the RAM 112 is cleared (step S501). Next, whether or not the game is a replay game is determined based on whether or not the replay flag based on the replay winning of the previous game is set in the RAM 112 (step S502).

If it is determined that the game is a replay game, the value of the BET counter is incremented by 1 (step S503), whereby the value of the BET counter is a specified number corresponding to the gaming state (the replay winning is the initial gaming state) Alternatively, since it occurs at RT, it is always determined whether or not 3) (step S504). Steps S503 and S504 are repeated until the value of the BET counter reaches the specified number. When the value of the BET counter reaches the specified number, the start switch 41 waits for detection of the operation of the start lever 11. (Step S505). When the operation of the start lever 11 is detected, the process returns to the flowchart of FIG.

  If the game is not a replay game, it is determined whether or not the value of the BET counter is a specified number corresponding to the gaming state (step S506). If the value of the BET counter is a specified number, it is determined whether or not the value of the credit counter in which the credit value is stored in the RAM 112 is 50 (step S507). If the value of the credit counter is 50, the flow path switching solenoid 49 is turned off, and the insertion of a new medal is prohibited with the medal flow path as the payout side (step S508). Then, the process proceeds to step S510. When the value of the BET counter is not a prescribed number according to the gaming state, or when the value of the credit counter is not 50, the flow path switching solenoid 49 is turned on and the medal flow path is set to the hopper 80 side to insert the medal. Is possible (step S509). Then, the process proceeds to step S510.

  In step S510, it is determined whether or not both the value of the credit counter and the value of the BET counter are zero. If neither the value of the credit counter nor the value of the BET counter is 0, it is determined whether or not the operation of the settlement button 16 is detected by the settlement switch 47 (step S511). If the operation of the checkout button 16 is detected, a checkout process is performed to control paying out medals for the values stored in the credit counter and the BET counter (step S512). Details of the settlement process will be described later. Then, the process returns to step S506.

  If both the value of the credit counter and the value of the BET counter are 0, or if the operation of the checkout button 16 is not detected, it is determined whether or not the inserted medal sensor 44 detects passage of the inserted medal (step S513). . If the passage of the inserted medal is detected, it is determined whether or not the value of the BET counter is a specified number corresponding to the gaming state (step S514). If the value of the BET counter is not a specified number, the value of the BET counter is incremented by 1 (step S515), and the process returns to step S506. If the value of the BET counter is a specified number, it is determined whether or not the value of the credit counter is 50 (step S516). If the value of the credit counter is not 50, the process directly returns to step S506. If the value of the credit counter is 50, the credit counter value is incremented by 1 (step S517), and the process returns to step S506.

  If the passage of the inserted medal is not detected, it is determined whether or not the value of the BET counter is a specified number corresponding to the gaming state (step S518). If the value of the BET counter is a specified number, it is determined whether or not the start switch 41 detects the operation of the start lever 11 (step S519). If the operation of the start lever 11 is not detected, the process returns to step S506. If the operation of the start lever 11 is detected, the flow path switching solenoid 49 is turned off, and the insertion of a new medal is prohibited with the medal flow path as the payout side. Further, the operations of the single BET button 14, the MAXBET button 15, and the settlement button 16 are invalidated (step S520). Then, the BET process is terminated, and the process returns to the flowchart of FIG.

  If the value of the BET counter is not a specified number, it is determined whether or not the value of the credit counter is 0 (step S521). If the value of the credit counter is 0, the process returns to step S506. If the value of the credit counter is not 0, it is determined whether or not an operation of the single BET button 14 is detected by the single BET switch 45 (step S522). If the operation of the single BET button 14 is not detected, it is determined whether or not the operation of the MAXBET button 15 is detected by the MAXBET switch 46 (step S523). If the operation of the MAXBET button 15 is not detected, the process returns to step S506.

  If the operation of the single BET button 14 is detected, the credit counter value is decremented by 1 (step S524), and the BET counter value is incremented by 1 (step S525). Then, the process returns to step S506.

  If the operation of the MAXBET button 15 is detected, it is determined whether or not the value of the credit counter is 0 (step S526). If the value of the credit counter is not 0, the value of the credit counter is decremented by 1 (step S527), and the value of the BET counter is incremented by 1 (step S528). Here, it is determined whether or not the value of the BET counter has reached a specified number corresponding to the gaming state (step S529). If the value of the BET counter is a specified number, the process returns to step S506. If the value of the BET counter is not the specified number, the process returns to step S526. If it is determined in step S526 that the value of the credit counter is 0, the process returns to step S506.

  Next, the payment process in step S512 will be described in detail. FIG. 16 is a flowchart showing in detail the settlement process executed by the CPU 111 in step S512. In the settlement process, the flow path switching solenoid 49 is turned off, and the insertion of a new medal is prohibited with the medal flow path set as the payout side (step S601). Further, the hopper motor 82 is driven in an ON state (step S602).

  Next, it is determined whether or not the value of the credit counter is 0 (step S603). If the value of the credit counter is 0, it is determined whether or not the value of the BET counter is 0 (step S604). If either the credit counter value or the BET counter value is not 0, it is determined whether or not the payout sensor 81 detects the payout of medals (step S605). If no medal payout is detected, the process returns to step S603.

  If a medal payout is detected, it is further determined whether or not the value of the credit counter is 0 (step S606). If the value of the credit counter is not 0, the credit counter value is decremented by 1 (step S607), and the process returns to step S603. If the value of the credit counter is 0, the value of the BET counter is decremented by 1 (step S608), and the process returns to step S603.

  If the value of the credit counter and the value of the BET counter are both 0 in steps S603 and S604, the hopper motor 82 is turned off to stop driving (step S609). Then, the settlement process is terminated and the process returns to the original process.

  Next, the lottery process in step S403 will be described in detail. FIG. 17 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 S701). If the gaming state is not the big bonus, the process proceeds to step S704 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 S702). 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. A regular bonus medium flag is set to the game state and the gaming state is controlled to the regular bonus (step S703). Then, the process proceeds to step S704. If the gaming state is a regular bonus, the process proceeds to step S704 as it is.

  In step S704, the betting number counted by the BET counter is read. Next, based on whether or not the regular bonus flag is set in the RAM 112, 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) (step S705). If there is a regular bonus, it is determined whether or not the read bet number is 1 (step S706). If not in the regular bonus, it is determined whether or not the read bet number is 3 (step S707). When the bet number read at step S706 is not 1 or when the bet number read at step S707 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 S706 is 1, or when the bet number read in step S707 is 3, the process proceeds to step S708.

  In step S708, 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 that is a value that should be originally taken (step S709). 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 for internal lottery in the RAM 112 (step S710). Details of the random number acquisition process will be described later.

  Next, in correspondence with the current gaming state, the lottery target combination registered in the winning combination table according to gaming state in FIG. 5B is sequentially read (step S711). Next, the common flag setting status registered in the role-specific table of FIG. 5C for the read lottery target role is acquired (step S712). As a result, it is determined whether the common flag is set (step S713).

  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 S714). Then, the process proceeds to step S716. 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 S715). Then, the process proceeds to step S716.

  In step S716, the number of determination values acquired in step S714 or S715 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 internal lottery random value. 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 S717).

  If no overflow has occurred, it is determined whether there is a combination that is not yet a processing target among the lottery targets in the gaming state (step S718). If there is something that has not yet been processed, the process returns to the process of step S711, and the process continues 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 S728.

  If an overflow occurs, it is determined whether or not the lottery target combination read in the previous step S711 is any of regular bonus + cherry, big bonus (1) + cherry or big bonus (2) + cherry ( Step S719). In the case of regular bonus + cherry, big bonus (1) + cherry or big bonus (2) + cherry, at least the game state in the current game is a regular bonus (if provided 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 S720). If none of the regular bonus winning flag, big bonus (1) winning flag and big bonus (2) winning flag are set, the first RT counter value is initialized to 0 regardless of the current value, 102 is set in the 2RT counter (step S721). Thus, the gaming state is controlled to the second RT until the regular bonus, the big bonus (1), or the big bonus (2) is won. Further, the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is set in the RAM 112 according to the read lottery target combination, and the cherry winning flag is set in the RAM 112 (step S722). Then, the process proceeds to step S728.

  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 S720, only the cherry winning flag is set in the RAM 112 (step S723). Then, the process proceeds to step S728.

  In step S719, when the lottery target is neither regular bonus + cherry, big bonus (1) + cherry or big bonus (2) + cherry, the lottery target is regular bonus, big bonus (1) or big It is determined whether the bonus is (2) (step S724). If the lottery target is neither the regular bonus, the big bonus (1), or the big bonus (2), the process proceeds to step S727. 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 S725).

  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 S728. If none of the regular bonus winning flag, big bonus (1) winning flag and big bonus (2) winning flag is set, it may be a regular bonus, big bonus (1) or big bonus (2). Regardless of the current value, the value of the first RT counter is initialized to 0 and 102 is set in the second RT counter (step S726). Thus, the gaming state is controlled to the second RT until the regular bonus, the big bonus (1), or the big bonus (2) is won. Then, the process proceeds to step S727.

  In step S727, the winning flag of the lottery object combination is set in the RAM 112. Here, if the lottery target role is regular bonus + cherry, the regular bonus winning flag and the cherry winning flag are set redundantly. In addition, the lottery is not a regular bonus, a big bonus (1), or a big bonus (2), and either a regular bonus winning flag, a big bonus (1) winning flag or a big bonus (2) winning flag is already set. If it has been 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 S727). . Then, the process proceeds to step S728.

  In step S728, a winning status notification command is generated in accordance with 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 S710 will be described in detail. FIG. 18 is a flowchart showing in detail the random number acquisition process executed by the CPU 111 in step S710. In the random number acquisition process, first, an interrupt to the CPU 111 is prohibited (step S801). 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 S802).

  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 S803). Next, the value of the random number stored in the general-purpose register 111GR is ANDed with 8080h (step S804). 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 S805). Then, after permitting the interrupt prohibited in step S801 (step S806), 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. 19 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 S901). 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 S902).

  Next, the work initialization code at the start of the reel motor rotation is set in the register, and the reel rotation is started (step S903). 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 S904). 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 reel that is rotating (step S905), and the work initialization code at the completion of stop preparation is set in the register (step S906). Thereby, the operation of the stop buttons 12L, 12C, and 12R becomes valid.

  Next, it is determined whether any one of the stop buttons 12L, 12C, and 12R has been detected (step S907). 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 S908). 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 S909 and S910). If no error is determined in steps S908 to S910, the process returns to step S907.

  If it is determined in step S909 that a loading error has occurred, or if it is determined in step S910 that a dispensing error has occurred, an error code indicating a loading / dispensing error during reel rotation is set in the register (step S910). In step S911, the process proceeds to predetermined error processing (step S912). If the error is released, the process returns to step S907 again.

  If it is determined in step S908 that a reel rotation error has occurred, an error code indicating a reel rotation error is set in the register (step S913), and the process proceeds to a predetermined error process (step S914). Along with this, the rotation of the reels 3L, 3C, 3R is also temporarily stopped. When the error is released, the process returns to step S903 again, and the rotation of the reels 3L, 3C, 3R is resumed.

  When the operation of the stop button 12L, 12C, or 12R is detected in step S907, the reel motor (any of 3ML, 3MC, and 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 as the stop operation position) is acquired and set to the work corresponding to the stop reel (step S915). 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 S916). Then, it waits until rotation of the reel (any one of 3L, 3C, 3R) corresponding to the operated stop button stops (step S917).

  Then, when the rotation of the reel (3L, 3C, or 3R) corresponding to the operated stop button is stopped, it is determined whether or not all of the reels 3L, 3C, and 3R are stopped (step S918). If the rotation of the reels 3L, 3C, 3R is not stopped, the process returns to step S905. 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. 20 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 S1001). 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 (step S1002).

  If the combination of symbols for the combination is complete, a winning flag for the combination is set in the RAM 112 (step S1003), and the process proceeds to step S1004. If the symbol combination of the combination is not complete, the process proceeds to step S1004. If RT symbols are prepared in the initial gaming state, the RT winning flag is set in the RAM 112. However, if the RT symbols are all in the other gaming state, the RT winning flag is set. There is nothing.

  In step S1004, 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 S1001 to read the next winning combination corresponding to the gaming state.

  If all of the winning combinations corresponding to the gaming state are targeted for winning determination, it is next determined whether or not a replay winning is made based on whether or not the replay winning flag is set in the RAM 112 (step S1005). If a replay prize has been won, a replay game flag is set in the RAM 112 (step S1006). 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 S1020.

  If no replay winning is made, it is determined whether or not the big bonus (1) is won depending on whether or not the big bonus (1) winning flag is set in the RAM 112 (step S1007). 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. Also, the values of the first RT counter and the second RT counter in the RAM 112 are both initialized to 0 (step S1008). Then, the process proceeds to step S1020.

  If the big bonus (1) has not been won, it is determined whether or not the big bonus (2) has been won according to whether or not the big bonus (2) winning flag is set in the RAM 112 (step S1009). 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. Further, the values of the first RT counter and the second RT counter in the RAM 112 are both initialized to 0 (step S1010). Then, the process proceeds to step S1020.

  If the big bonus (2) has not been won, it is determined whether or not the regular bonus has been won according to whether or not the regular bonus winning flag is set in the RAM 112 (step S1011). 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 values of the first RT counter and the second RT counter in the RAM 112 are both initialized to 0 (step S1012). Then, the process proceeds to step S1020.

  If there is no regular bonus winning, the regular bonus flag is not set in the RAM 112, and the game state in the current game is the initial game state depending on whether both the first RT counter and the second RT counter are 0 or not. Is determined (step S1013). If the game state in the current game is not the initial game state, the process proceeds to step S1020.

  If the game state in the current game is the initial game state, it is determined whether or not a bell is won depending on whether or not a bell winning flag is set in the RAM 112 (step S1014). If the bell is won, 1001 is set as the initial value of the first RT counter of the RAM 112 (step S1015). Here, to set 1001 as the initial value, the value of the first RT counter is decremented by 1 in step S1114 (described later) until the next game is started. This is to secure 1000 games as the number of games. Then, the process proceeds to step S1020.

  If the bell has not been won, it is determined whether or not a watermelon has been won according to whether or not a watermelon winning flag is set in the RAM 112 (step S1016). If the watermelon has been won, 101 is set as the initial value of the second RT counter in the RAM 112 (step S1017). Here, to set 101 as the initial value, the value of the second RT counter is decremented by 1 in step S1112 (described later) until the next game is started. This is to secure 100 games as the number of games. Then, the process proceeds to step S1020.

  If no watermelon winning has been made, it is determined whether or not a cherry has been won according to whether or not a cherry winning flag is set in the RAM 112 (step S1018). If the cherry is won, 102 is set as the initial value of the second RT counter in the RAM 112 (step S1019). Here, by setting 102 as the initial value, how many games have elapsed until the value of the second RT counter is initialized to 0 after winning the regular bonus, the big bonus (1) or the big bonus (2). However, the gaming state is controlled to the second RT. Then, the process proceeds to step S1020.

  In step S1020, winning information indicating the type of winning combination based on the winning flag set in the RAM 112 (however, in the case of losing, the winning flag is not set) and the number of medals to be paid out with the winning. A command is generated and transmitted to the effect control board 102. 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. 21 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 is a small prize winning accompanied by a medal payout depending on whether or not any of the watermelon, bell and cherry winning flags is set in the RAM 112 (step S1101). If the small role is not won, the process proceeds to step S1103.

  If the small role winning is achieved, the number of medals is sequentially paid out by controlling the hopper 80. However, the number of credits is increased instead of paying out medals until the number of credits accumulated as data reaches 50 (step S1102). Then, the process proceeds to step S1103.

  In step S1103, it is determined whether or not the current gaming state is a regular bonus (including those provided during the big bonus) depending on whether or not the regular bonus flag is set in the RAM 112. If the current gaming state is not a regular bonus, the process proceeds to step S1107. If the current gaming state is a regular bonus, the counter of the RAM 112 is used to count the number of games and the number of winnings in the regular bonus (step S1104).

  As a result of the counting, it is determined whether or not a regular bonus end condition has been met (step S1105). If the regular bonus end condition is satisfied, the regular bonus medium flag in the RAM 112 is deleted. In addition, a counter value for counting the number of games and the number of winnings in the regular bonus is initialized (step S1106). Here, since the value of the first RT counter and the value of the second RT counter are both 0, the gaming state in the next game is the initial gaming state. Then, the process proceeds to step S1107. Even if the regular bonus is not terminated, the process proceeds to step S1107.

  In step S1107, it is determined whether or not the current gaming state is a big bonus depending on whether or not the big bonus flag is set in the RAM 112. If the current gaming state is not a big bonus, it is determined whether or not the value of the first RT counter in the RAM 112 is greater than 0 (step S1108). If the value of the first RT counter is larger than 0, the value of the first RT counter is subtracted by 1 (step S1109), and the process proceeds to step S1112. If the value of the first RT counter is 0, it is determined whether the value of the second RT counter is greater than 0 and less than 102 (step S1110). If the value of the second RT counter is larger than 0 and smaller than 102, the value of the second RT counter is decremented by 1 (step S1111), and the process proceeds to step S1112. If the value of the second RT counter is 0 or 102, the process proceeds to step S1112 as it is.

  In step S1112, based on the big bonus medium flag and the regular bonus medium flag in the RAM 112 and the values of the first RT counter and the second RT counter, a game state command indicating a game state applied in the next game is generated, Transmit to the control board 102. Then, the process proceeds to step S1124.

  If the current gaming state is a big bonus in step S1107, the number of payout medals in the big bonus is counted using the counter of the RAM 112. The number of payout medals counted here exceeds 465, and it is determined whether or not the big end condition is satisfied (step S1114). If the big bonus end condition is not satisfied, a game indicating a game state applied in the next game based on the big bonus medium flag and the regular bonus medium flag in the RAM 112 and the values of the first RT counter and the second RT counter. A state command is generated and transmitted to the effect control board 102 (step S1115). Then, the process proceeds to step S1124.

  If the big bonus end condition is satisfied, the big bonus medium flag in the RAM 112 is deleted. If the regular bonus medium flag is set, it is also deleted. In addition, since there may be a regular bonus in the big bonus that initializes the value of the counter for counting the number of paid-out medals in the big bonus, the value of the counter for counting the number of games and winnings in the regular bonus Is initialized (step S1116). Here, since the value of the first RT counter and the value of the second RT counter are both 0, the gaming state in the next game is the initial gaming state.

  Further, a gaming state command indicating a gaming state (here, always a big bonus) applied in the next game based on the big bonus medium flag and the regular bonus medium flag in the RAM 112 and the values of the first RT counter and the second RT counter. Is generated and transmitted to the effect control board 102 (step S1117). Here, timing of the wait time is started using the internal timer of the CPU 111 (step S1118).

  When the timing of the wait time is started, it is determined whether or not the value of the credit counter in the RAM 112 is 0 (step S1119). If the value of the credit counter is 0, the process proceeds to step S1123. If the value of the credit counter is not 0, it is determined whether or not an operation of the settlement button 16 is detected by the settlement switch 47 (step S1120). When the operation of the settlement button 16 is detected, the settlement process shown in FIG. 12 is performed (step S1121). Then, the process proceeds to step S1123. In step S1123, it is determined whether or not the time being measured has reached the specified weight time. If the specified time has not been reached, the process returns to step S1119. If the specified time has been reached, the process proceeds to step S1124.

  In step S1124, 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 S1003, it is deleted. 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 performs the transition of the game state among the initial game state, the first RT, the second RT, the big bonus, and the regular bonus, depending on the progress of the game. The command is transmitted to the effect control board 102. On the other hand, the CPU 121 of the effect control board 102 performs an original effect based on the command received from the game control board 101. Hereinafter, the process of the effect performed by the control on the effect control board 102 side will be described.

  22 and 23 are flowcharts showing processing executed by the CPU 121 of the effect control board 102. On the effect control board 102 side, it is determined whether or not a command sent from the game control board 101 has been received (step S1201). When any command is received from the game control board 101, it is determined what kind of the received command is (step S1202).

  If the received command type is the winning status notification command transmitted in step S728, the winning status stored in the winning status saving area of the latest game in the previous game (that is, the winning flag in the previous game) Is set in the RAM 122, and the winning status (that is, the setting status of the winning flag in the current game) indicated by the received winning status notification command is provided in the RAM 122. The latest game winning status is saved in the save area (step S1203).

  Next, it is determined whether or not the gaming state stored in the storage area of the latest game in step S1227 of the previous game (that is, the gaming state in the current game) indicates a big bonus or a regular bonus (step S1204). ). If the game state in the current game is not a big bonus or a regular bonus, it is determined whether or not a bonus winning notification has already been made in the previous game (step S1205). If the game state in the current game is a big bonus or a regular bonus in step S1204, or if a bonus winning notification has already been made in step S1205, the process directly returns to step S1201.

  If no bonus winning notification has been made in the previous game, it is determined whether or not the value of the continuous counter in the RAM 122 is 0, that is, whether or not a continuous effect has not yet been executed (step S1206). If the value of the continuous counter is not 0, continuous production has already started, and the process proceeds to step S1210.

  If the value of the continuous counter is 0, it is determined whether or not the gaming state saved in the save area of the latest game in step S1227 of the previous game (that is, the gaming state in the current game) is in the second RT. (Step S1207). If the game state in the current game is the second RT, the stop symbol table in which the stop symbol is stored in step S1212 (described later) in the previous game (at this time, the stop symbol of the previous game has not yet been cleared) ), It is determined whether or not any combination is won in the current game (step S1208).

  If no winning combination has been won in the previous game, 3 is set as an initial value in the continuous counter of the RAM 122 (step S1209). Then, the process proceeds to step S1210. If it is not in the second RT in step S1207, or if any winning combination is won in step S1208, the process returns to step S1201 as it is. In step S1210, in accordance with the value of the continuous counter in the RAM 122, the effect for the current game is started from the continuous effects that are continued in three games. Then, the process returns to step S1201.

  If the received command type is the reel rotation command transmitted in step S904, the information regarding the stop symbols of the reels 3L, 3C, 3R stored in the RAM 122 in the previous game is cleared (step S1211). Then, the process returns to step S1201.

  If the received command type is the reel stop command transmitted in step S916, 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 S1212).

  Next, with reference to the stop symbol table, it is determined whether all of the reels 3L, 3C, 3R are stopped and a chance is derived to the variable display device 2 (step S1213). If the chance is not derived, the process directly returns to step S1201. If the chance is derived, a chance effect indicating the possibility of winning the regular bonus, the big bonus (1) or the big bonus (2) is performed (step S1214). Then, the process returns to step S1201.

  If the received command type is the winning information command transmitted in step S1020, whether the winning information command indicates a winning of regular bonus, big bonus (1) or big bonus (2). It is determined whether or not (step S1215). If any one of the regular bonus, the big bonus (1), and the big bonus (2) is shown, it is determined whether or not the value of the continuous counter in the RAM 122 is 0, that is, whether or not the continuous effect is executed. (Step S1216). If the value of the continuous counter is 0, that is, if the continuous effect is not executed, the process proceeds to step S1219.

  If the value of the continuous counter is not 0, that is, if the continuous effect is being executed, the continuous effect being executed is forcibly terminated (step S1217), and the value of the continuous counter is cleared to 0 (step S1218). Then, the process proceeds to step S1219. In step S1219, if a bonus winning notification has been made, this is terminated. Thereafter, by displaying a predetermined image on the liquid crystal display 4, etc., a bonus winning effect indicating a winning of the regular bonus, the big bonus (1) or the big bonus (2) is performed (step S1220). Then, the process returns to step S1201.

  If none of the regular bonus, the big bonus (1), and the big bonus (2) has been won in step S1215, whether or not the value of the continuous counter in the RAM 122 is 0, that is, a continuous effect has been executed. It is determined whether there is any (step S1221). If the value of the continuous counter is 0, that is, if the continuous effect is not executed, the process returns to step S1201 as it is.

  If the value of the continuous counter is not 0, that is, if the continuous effect is being executed, the result of the continuous effect for the current game is shown (step S1222), and the value of the continuous counter in the RAM 122 is decremented by 1 (step S1223). As a result of this subtraction, it is determined whether or not the value of the continuous counter is 0, that is, whether or not the continuous production is to be ended in the current game (step S1224). If the value of the continuous counter is not 0, the process returns to step S1201.

  When the value of the continuous counter becomes 0, it is determined whether or not the winning status stored in the RAM 122 in step S1203 indicates winning of the regular bonus, the big bonus (1), or the big bonus (2). (Step S1225). If any of the regular bonus, the big bonus (1), and the big bonus (2) is not indicated, the process returns to step S1201. If the bonus of regular bonus, big bonus (1) or big bonus (2) is shown, the bonus winning that informs the player of the winning of these roles by displaying a predetermined image on the liquid crystal display 4, etc. Notification is performed (step S1226). Then, the process returns to step S1201.

  When the received command type is the gaming state command transmitted in step S1112, S1115, or S1117, the gaming state stored in the storage area of the gaming state of the latest game in the previous game (that is, the current gaming state command) The game state in the game) is moved to the previous game state storage area provided in the RAM 122, and the game state indicated by the received game state command (that is, the game state in the next game) is stored in the RAM 122. The game state is saved in the save area (step S1227).

  Next, it is determined whether or not the game state of the next game stored in the latest game storage area indicates the initial game state (step S1228). If the game state of the next game is not the initial game state (in this case, the game state of the current game is not a big bonus), the process directly returns to step S1201. If the game state of the next game is the initial game state, for example, an image displayed on the liquid crystal display 4 notifies that the game state of the next game is the initial game state (step S1229). Then, the process proceeds to step S1230.

  In step S1230, it is determined whether or not the big bonus has ended in the current game with reference to the game state for two times stored in the RAM 122. If the big bonus has not ended in the current game, that is, if the game state of the next game is also a big bonus, or if the game state in the current game is not a big bonus, the process returns to step S1201.

  When the big bonus is ended in this game, since the game control board 101 is controlled to be in a frozen state, the display of the image on the liquid crystal display 4, the output of sound from the speakers 7L and 7R, The lighting of all the lamps such as the game effect LEDs 75A to 75M is stopped, and all the effects being executed on the effect control board 102 side are stopped (step S1231).

  Next, timing of the wait time is started using the internal timer of the CPU 121 (step S1232). Then, it is determined whether or not the time being counted has reached the specified wait time (step S1233). If the specified time has not been reached, the process of step S1233 is repeated. If the specified time has been reached, the end of the big bonus is notified by the image displayed on the liquid crystal display 4 and the sound output from the speakers 7L and 7R (step S1234). Then, the process returns to step S1201.

  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 S1235). Thereafter, the process returns to step S1201.

  Note that the specified time (effect side specified time) in step S1233 is set to be shorter than the specified time (game side specified time) in step S1123 of FIG. Since the effect side specified time is set shorter than the game side specified time, the player is notified of the end or continuation of the big bonus while in the freeze state.

  As described above, in the slot machine 1 according to this embodiment, there are RTs as game states other than the initial gaming state, the regular bonus, and the big bonus, and there are two types of RTs, the first RT and the second RT. is there. Here, in the first RT, the number of replay judgment values is only 1 in the initial gaming state, and the medal payout rate is almost the same as in the initial gaming state, and is smaller than 1, but the second RT is in the replaying. The winning probability is extremely high compared to the initial gaming state, and the medal payout rate exceeds 1.

  When the watermelon is derived in the initial gaming state, the second RT of 100 games, to the first RT of 1000 games when the bell is derived, and when the cherry is derived, the next regular bonus, big bonus (1) or big bonus ( It is controlled by the second RT until winning 2). However, when it is already controlled to the first RT or the second RT, even if watermelon, bell, or cherry is derived as the display result of the variable display device 2, it is not controlled to a new RT. As described above, since there are a plurality of types of RTs having different degrees of advantage, the progress of the game becomes various, and the interest of the game can be improved.

  Also, depending on whether watermelon, bell, or cherry is derived as the first role to be derived after being controlled to the initial gaming state, there is a difference in the replay winning probability and the number of continuous games in RT, so the initial gaming state In this case, the player can be interested in the display result derived to the variable display device 2, and the interest of the game can be improved. Moreover, in the first RT, the medal payout rate is smaller than 1, and the player's handed medal decreases, but in the second RT, the medal payout rate is larger than 1, and the player's handed medal is Since it will increase, the player's interest in which kind of small role will be derived first after being controlled to the initial gaming state is extremely high.

  In addition, even if there is no regular bonus, big bonus (1) or big bonus (2) after the first gaming state is controlled to the first RT, the first RT is completed after the completion of 1000 games, and the initial game is started again. It will return to the state. Even if there is no regular bonus, big bonus (1), or big bonus (2) after being controlled to the second RT based on the watermelon prize, the second RT will be completed with 100 games and the initial game will start again. It will return to the state. As described above, the first RT or the second RT may return to the initial gaming state again without endlessly, so that the manner in which the gaming state is transitioned is varied, and the interest of the game can be further improved.

  Even if it is controlled to the first RT once, it will return to the initial gaming state by digesting 1000 games, so that if the watermelon or cherry is newly derived here, it can give the player a sense of expectation that it will be controlled to the second RT. . For this reason, even if it is once controlled to the second RT, the player's sense of expectation is not completely lost. Even if the second RT based on the derivation of watermelon is terminated by the digestion of 100 games and returns to the initial gaming state again, if the watermelon or cherry is newly derived here, it is controlled again to the second RT, The player's expectation will not be lost just because the second RT has ended.

  Further, when the bell is won in the initial game state, the first RT is controlled. However, since the bell is not missed at the time of winning, the winning probability is the same as the winning probability. Here, the winning probability of the bell in the initial gaming state is 3370 / 16384≈1 / 4.8. The probability of winning one of watermelon, bell, and cherry is 4087 / 16384≈1 / 4.0 (when the set value is 1). For this reason, since the initial gaming state is expected to be completed in several games, there is no possibility that the game continues in the initial gaming state and the player is irritated.

  The first RT cannot be said to be an advantageous gaming state compared to the initial gaming state because the initial gaming state and the replay winning probability can only be equated, but the second RT has a replay winning probability compared to the initial gaming state. Can be said to be a very advantageous gaming state. Therefore, not only the expectation of whether the first RT or the second RT, but also the expectation that the player wants to leave the initial gaming state and shift to the second RT at an early stage can be given to the player. be able to.

  In addition, the advantage of the controlled RT varies depending on the type of the small role derived first after being controlled to the initial gaming state, but the next game is played in the initial gaming state. When it becomes, it will be notified to the player to that effect. Therefore, the variable display device can be used when there is no possibility that the player has been controlled from the initial gaming state to RT (first RT or second RT) without being noticed, and there is a possibility that the player will be newly controlled by RT. It becomes possible to attract the player's interest in the display result derived to 2.

  Also, the role that triggers the control of the gaming state from the initial gaming state to the RT (first RT or second RT) is a small role of watermelon, bell, cherry, and a separate role for controlling the gaming state to RT is provided separately There is no need. For this reason, the types of winning combinations can be suppressed to a certain type, and the game in the slot machine 1 is not complicated. Further, since the types of winning combinations are not increased, the internal lottery process and the reel 3L, 3C, 3R stop control are not complicated.

  Furthermore, the bell that will be controlled to the first RT whose medal payout rate is smaller than 1 is a role that will be won without missing if it is won by internal lottery, but the medal payout rate Even if the watermelon and cherry to be controlled to the second RT larger than 1 are won by the internal lottery, depending on the operation timing of the stop buttons 12L, 12C, and 12R, it is a role that causes the loss. Thus, in order to control the second RT, which is advantageous to the player, it is necessary for the player to intervene in the technology, so that the player's profits differ depending on the skill, and the game's interest is further improved. Can be made.

  Also, after the setting value is changed (regardless of whether or not the setting value is actually changed), the game is controlled to the initial gaming state, so that it is controlled by any kind of RT. Can give the player a fair chance. In addition, even after the regular bonus or big bonus ends, the game is controlled to the initial gaming state, so that the player's interest is not reduced by the regular bonus or big bonus being ended, and further gaming Can improve the interest of

  Even after being controlled to the first RT by deriving the bell, if the regular bonus, the big bonus (1) or the big bonus (2) is won, the second RT is controlled. If no winning combination is won in 2RT, continuous production over three games will be started. Even when the display result of losing is derived without winning any of the roles, the player can feel the expectation of the player by starting the continuous production, and the interest of the game can be improved. .

  Here, if the regular bonus, the big bonus (1), or the big bonus (2) is won when the continuous effects over the three games are finished, a bonus winning notification is performed. In this way, the continuous production is a game that makes the player expect the winning of the regular bonus, the big bonus (1) or the big bonus (2) from the game before the result is shown, and has a very high production effect. As a result, the interest of the game can be improved.

  The continuous performance is an effect that makes the player expect the regular bonus, the big bonus (1), or the big bonus (2) to be won, but even if these roles are won in the first RT, the game state in the second RT The continuous production is started after is controlled. The second RT has a very high replay winning probability, and even when the regular bonus, big bonus (1), or big bonus (2) is also won, the replay is given priority and the start of continuous production From the end of the game to the end, the player's expectation can be raised without winning the regular bonus, the big bonus (1) or the big bonus (2) as much as possible.

  Furthermore, although it is stipulated that none of the roles has been won as an opportunity to start the continuous production, regular bonus, big bonus (1) or big bonus ( Since the winning of 2) is not possible, it will not be known that the regular bonus, the big bonus (1) or the big bonus (2) is not won in the game where the continuous production is started, and the production is meaningless It can be made not to let it be. On the other hand, the fact that he did not win any role in the 2nd RT, which has a very high replay win probability, means that he may have won the regular bonus, big bonus (1) or big bonus (2). Therefore, the player can be expected to win the regular bonus, the big bonus (1), or the big bonus (2) without discouraging the player.

  If the chance is derived as the display result of the variable display device 2, it means that the regular bonus, the big bonus (1) or the big bonus (2) may be won. In this case, the liquid crystal display Chance production is also performed in the vessel 4. For this reason, even if the beginner is relatively unfamiliar with the game and cannot determine whether the display result of the variable display device 2 is a chance, the regular bonus, the big bonus (1), or the big bonus (2) You will be able to know for sure that you may have won.

  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, in the initial gaming state or RT, the number of determination values includes those for which both regular bonus, big bonus (1), big bonus (2) and cherry are subject to lottery. 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 cherry are won.

  Here, even if the winning of the cherry is won based on the display result of the variable display device 2 based on the cherry winning flag set based on the winning of the cherry which 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 the cherry, the player can be expected to win the regular bonus, the big bonus (1), or the big bonus (2), and the fun of the game can be improved.

  Even if the cherry winning flag is set, the cherry may be missed depending on the operation timing of the stop button 12L, and the payout number of medals is relatively small, but if you win in the initial gaming state, the next regular This is a role for controlling the gaming state to the second RT until a bonus, a big bonus (1) or a big bonus (2) is won. In addition, the winning of the regular bonus, the big bonus (1) or the big bonus (2) can be expected by winning. Thus, even if the number of medals to be paid out is small, it is possible to further improve the interest of the game by providing a small role with a great expectation given to the player.

  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. 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 Along with the transition to (setting change process), the data stored in the RAM 112 is initialized. 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.

  By the way, each game in the slot machine 1 is started when the control is shifted to start the rotation of the reels 3L, 3C, 3R by the operation of the start lever 11, and is the display result derived to the variable display device 2? When the small combination is won according to the display result, the process ends when the medal payout is completed. During the period from the start to the end of the game, setting of the number of bets and the settlement of credits are prohibited. Here, the freeze state when the big bonus ends is controlled after it is determined that one game has ended.

  In the frozen state, the progress of the game is disabled, so the setting of the number of bets remains prohibited. However, the credit settlement is canceled when it is determined that the game has ended before being controlled to the frozen state. Has become. For this reason, even if the bet number setting is prohibited due to the controlled freezing state, it is possible for the player to settle the credit, so that the player's will is reflected as much as possible. A medal can be paid out according to the credit stored as the medal owned by the user.

  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 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 the above embodiment, the continuous production is started when the display result of the loss is derived to the variable display device 2 in the second RT. However, the continuous performance is to finally notify the winning of the regular bonus, the big bonus (1), or the big bonus (2), and makes the player expect the winning of these roles. Therefore, when the regular bonus, the big bonus (1) or the big bonus (2) is won in the internal lottery, or when all the combinations are lost, the continuous production may be started.

  In the above embodiment, when a game state command is received at the end of one game, an initial notification is made based on this. Therefore, in the first game after changing the set value, although it is controlled to the initial game state, the player is not notified that the game is performed in the initial game state. Therefore, for example, even when the set value is changed and the game state command is controlled to the initial game state, the game state command is transmitted from the game control board 101 to the effect control board 102, and the CPU 121 of the effect control board 102 is at the start of one game For example, when the winning status notification command is received, the gaming state stored in the RAM 122 is referred to, and if it is the initial gaming state, the initial notification may be performed. Also, a gaming state command may be transmitted from the gaming control board 101 to the effect control board 102 at the start of one game, and based on this, an initial notification may be made at the start of one game.

  However, even if the initial notification is not performed in the game immediately after the setting value is changed as in the above embodiment, if the initial notification is performed in the second game after the setting value is changed, the initial gaming state is set. The player knows that there is. As a result, the player who started the game from the time of opening the game store knows that the set value has been changed between the closing of the previous day and the opening of the store. Therefore, a command indicating that the setting value has been changed is transmitted from the game control board 101 to the effect control board 102, and the CPU 121 of the effect control board 102 first changes to the first RT or the second RT after the setting value is changed. Until the gaming state is controlled, the gaming state may not be notified even in the initial gaming state. Thereby, the change of the set value is not perceived by the player.

  Furthermore, the initial notification indicating that such a gaming state is controlled to the initial gaming state may not be performed at all. Even when the initial notification is not performed at all, the change of the set value is not perceived by the player. Also, if no initial notification is made, the player must count a huge number of games in order to know whether or not the first RT or second RT that has been controlled has been terminated by digesting the prescribed number of games. . For a player who has started playing a game after the game store opened, it is not known whether the game state is controlled to the initial game state. In particular, the first RT has no difference in replay winning probability that can be distinguished from the initial gaming state. For this reason, even if it is actually controlled by the first RT, the player can be expected to be controlled in the initial gaming state that may be controlled by the second RT.

  In the above embodiment, when the regular bonus, the big bonus (1) or the big bonus (2) is won while being controlled by the first RT, the first RT is terminated and the gaming state is controlled by the second RT. I was supposed to do. However, in such a case, although the first RT is terminated, the gaming state may be controlled to the initial gaming state instead of the second RT.

Further, when a predetermined special combination other than the regular bonus, the big bonus (1) and the big bonus (2) described above is provided and a predetermined special combination is won in the first RT or the second RT, the predetermined special combination is determined from the first RT or the second RT. The gaming state is controlled to a predetermined gaming state (for example, a bonus with a smaller expected value of the number of paid-out medals than a regular bonus or a big bonus, such as a bonus that lasts for one game or two games). After the gaming state is ended, the gaming state may be controlled to the initial gaming state. The predetermined special role may not be missed when winning. Even if there is no missing case, the first RT or the second RT may be terminated when a predetermined special role is won.
Here, it is preferable that the winning probability of the predetermined special role is smaller than the reciprocal of the number of continuing games of the second RT based on the derivation of watermelon (ie, 1/100).

  In this way, even after being controlled to the first RT or the second RT according to the type of the small role first derived in the initial gaming state, when the predetermined special role is won, the gaming state is controlled to the initial gaming state again. It has become. For this reason, since it is controlled to any type of RT and before the regular bonus, big bonus (1) or big bonus (2) is won, it may be controlled to a different type of RT. The progress mode of the game becomes abundant and the interest of the game can be further improved. Further, if the winning probability of a predetermined special role is made smaller than the reciprocal number of the second RT continuous game, it is advantageous for the player while avoiding frequent occurrence of the second RT puncture which is highly advantageous for the player. It can be said that the player's expectation is maintained even after the first RT is controlled to a low degree.

  Further, the RT that is terminated by a predetermined special combination may be only the first RT having a low advantage for the player. In this case, the winning probability of the predetermined special combination may be higher or lower than the reciprocal of the number of continuing games of the second RT based on the derivation of watermelon (that is, 1/100). In this case, even when the gaming state is in the first RT, the game is controlled to the initial gaming state after passing through the predetermined gaming state by winning a predetermined special role, and further, the first small role winning type there Accordingly, the player can be given a sense of expectation of being controlled by the second RT, and the interest of the game can be improved.

  In the above-described embodiment, the number of replay determination values in the first RT is one greater than the number of replay determination values in the initial gaming state, and the replay winning probability in the first RT is very small but the replay winning probability in the initial gaming state is very small. Was supposed to be higher than. However, the replay determination value number in the first RT may be smaller than the replay determination value number in the initial gaming state, and the replay winning probability in the first RT may be lower than the replay winning probability in the initial gaming state.

  In the above embodiment, the gaming state is controlled to the first RT or the second RT according to the type of the small role derived first in the initial gaming state, and the replay is derived in the initial gaming state. However, the first gaming state is not controlled by the first RT or the second RT. However, when the replay is derived in the initial gaming state, the gaming state may be controlled to either the first RT or the second RT (the one determined in advance corresponding to the replay). In addition, two types of replay A (for example, JAC-JAC-JAC) and Replay B (JAC-JAC-Bell) are prepared as replaying roles (each of which is separately subject to internal lottery), and in the initial gaming state When the replay A is first derived, the gaming state may be controlled by the first RT, and when the replay B is derived, the gaming state may be controlled by the second RT.

  In this way, when the gaming state is controlled to the first RT or the second RT by derivation of the replay, the winning probability of the initial gaming state A and the role to shift the gaming state to the second RT is higher (other roles ) And the initial gaming state B may be provided. When there are two types of replays, Replay A for shifting the gaming state to the first RT and Replay B for shifting the gaming state to the second RT, the first RT and the second RT are the same for the winning combination of the small role, Assuming that the game is not shifted to any of the above, (the winning probability of Replay B / the winning probability of Replay A) may be higher in the initial gaming state B than in the initial gaming state A.

  Here, in order to increase (winning probability of Replay B / winning probability of Replay A) in the initial gaming state B from the initial gaming state A, the winning probability as a whole replay is the same, but the winning probability of Replay B is Even if it is higher in the initial gaming state B than in the initial gaming state A, the winning probability of Replay A is the same, but the winning probability of Replay B may be higher in the initial gaming state B. That is, the initial gaming state B can be a chance RT that has a higher probability of shifting to the second RT than the initial gaming state A.

  When there are two types of initial game states A and B in this way, for example, the game state is controlled to the initial game state A after the regular bonus ends, and the game is moved to the initial game state B after the big bonus ends. It is good also as what controls a state. In addition, when the first RT is completed due to the digestion of the prescribed number of games, the gaming state can be controlled to the initial gaming state A. Note that the gaming state can be controlled to the initial gaming state A after the setting value changing operation is completed.

  As described above, the gaming state is controlled to the initial gaming state A after the end of the regular bonus, but after the big bonus is finished, the gaming state is controlled to the initial gaming state B where the medal payout rate easily exceeds the second RT. By doing so, the player can often receive the next bonus (regular bonus or big bonus) without reducing the medals on hand after the end of the big bonus. Thereby, the player's expectation for the big bonus can be further increased, and the interest of the game can be improved. Even when a bonus announcement is made, the player's interest in the type of bonus that has been won can be further increased.

  On the other hand, the initial gaming state B after the regular bonus has ended may be shifted to the second RT, so the player's expectation will not be reduced just because the regular bonus has been reached. Furthermore, the player's expectation for the big bonus can be further enhanced by controlling to the initial gaming state A instead of the initial gaming state B after the first RT is ended by digestion of the prescribed number of games. The interest of the game can be improved. Since the initial gaming state controlled after the setting value changing operation is also the initial gaming state A, the initial gaming state B with a high probability of shifting to the second RT is a special initial gaming state associated with the big bonus. It is possible to further increase the player's expectation for the big bonus and improve the interest of the game.

  Furthermore, the display mode for shifting the game state from the initial game state to the first RT or the second RT does not necessarily have to be a display mode of a winning combination such as a replay or a small role. It is good also as a predetermined display mode among the display modes of the losing that is derived by the operating procedure of the stop buttons 12L, 12C, 12R even when all the roles are lost in the internal lottery or even if any winning combination is won. .

  In the above embodiment, the gaming state is controlled to the first RT when winning a bell in the initial gaming state, and the gaming state is controlled to the second RT when winning a watermelon or cherry. In the second RT, the winning probability of a role other than replay is the same as that of the first RT, but the replay winning probability is higher than that of the first RT, so that the gaming state is more advantageous for the player than the first RT. However, the gaming status controlled when winning a watermelon or cherry is the same as the gaming status controlled when winning a bell, but the winning probability of each role is the same. Announce the operation procedure of the stop buttons 12L, 12C, 12R for winning (the player determines the operation timing of the stop buttons 12L, 12C, 12R to enter the winning combination by announcing the type of winning combination itself) It may be in a gaming state (so-called AT) that can be recognized, or that informs the operation sequence of the stop buttons 12L, 12C, and 12R in which a winning combination can be won or facilitated. AR which combined RT and AT may be sufficient.

  In the above embodiment, at the end of the big bonus, the freeze effect is controlled such that the progress of the game is disabled for a certain period of time and all the effects are stopped. It may be performed at the start of the game, that is, immediately after winning the big bonus (1) or the big bonus (2). Even when the freezing effect is performed at the start of the big bonus, only the settlement of credits can be performed as in the case of performing the freezing effect at the end of the big bonus. 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 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. 24 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. 25 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. And since the randomness of the processing random number is high, the randomness of the random number for internal lottery generated using the random number is also high.

  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. 26 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 fetches 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 this third modification, 11h is subtracted from the upper region data before the final exclusive OR operation (FIG. 26 (i)) of the upper region data and the lower region data (FIG. 26). 26 (e)), rotate 1 bit lower (FIG. 26 (f)), perform exclusive OR operation with lower area data (FIG. 26 (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. 26E to 26F are performed can be changed to an arbitrary order.

  Also, the value to be subtracted in FIG. 26 (e) is not limited to 11h, and any value other than 00h can be added or subtracted. In FIG. 26 (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. 26G 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 an exclusive OR operation on the data in the upper area in FIG. 26 (i) may be data that is first input to the lower area from the random number generation circuit 115. FIG. 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. 26 (h) may be 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. 26G 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. 26 (e) is performed, the data stored in the upper area of the RAM 112 is first stored in an accumulator (general 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. 26 (f), the accumulator data in which the result of the subtraction in FIG. 26 (e) is stored is rotated to the lower bit by bit, and the resulting data is stored again in the accumulator. In FIG. 26 (g), an exclusive OR operation is performed on the data stored in the lower area of the RAM 112 with respect to the accumulator data in which the result of the operation of FIG. 26 (f) is stored. Is stored in the accumulator. Since the accumulator is still functioning as the upper area of the RAM 112 at this time, the accumulator data may be stored in the lower area of the RAM 112 in FIGS. 26 (g) → (j).

  Furthermore, in FIG. 26 (h), the data in the saving area of the RAM 112 is loaded into the accumulator. Here, the accumulator functions as the saving area, and 11h is added to the accumulator data and stored in the accumulator. In FIG. 26 (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 data of the result of the exclusive OR operation of FIG. 26 (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 of generating random numbers for internal lottery in the third modification can change the processes in FIGS. 26A to 26D as shown in FIGS.

  In the example of FIG. 27, the random number generated by the random number generation circuit 115 is replaced by the sampling circuit 116 by changing the bit order of the upper 8 bits and the lower 8 bits, 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. 28, the connection of the wiring 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 sampled in the order in which the bits are arranged. (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. 29, 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. 30, 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 initial gaming state, the first RT or the second RT, the game can be started only by setting 3 as the bet number. On the other hand, even in the initial gaming state, the first RT or the second RT, the game can be started by setting 1 as the bet number, and further, the game can be started by setting 2 as the bet number. You may be able to do that.

  In the initial gaming state, when 1 or 2 is set as the bet number in the first RT and the second RT, the winning probability of the small role in the internal lottery is lowered and smaller than the case where 3 is set as the bet number. It is possible to increase the number of medals to be paid out when winning. In addition, in a slot machine in which any of 1, 2, or 3 can be set as the number of bets in the initial gaming state, the first RT and the second RT, the number of determination values is stored in common for all of the setting values 1 to 6. In addition, there may be a combination that is stored in common for all 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 game 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, “Replay-Replay-” based on the 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. In contrast, based on the current symbol position when the stop condition is satisfied and the setting status of the winning flag, pull-in control is performed so that the symbol of the winning symbol is aligned, or the symbol of the symbol that is not winning 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 align.

  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 peripheral portion, and the symbols are driven by rotational driving of these reels 3L, 3C, and 3R. Was variably displayed. However, a device that virtually displays a symbol on a display device such as a liquid crystal display device may be used instead of the variable display device 2 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.
