Abstract

PROBLEM TO BE SOLVED: To provide a slot machine for controlling the decision to allow the derivation of a small role display result and the actual derivation so as to prevent a player in a special game from acquiring only the game worth of the minimum number.SOLUTION: For an internal lottery random number of 16384, the number of determination values to be decided as a winning in the internal lottery is registered for each role lottery target. The roles for the internal lottery in a regular bonus are watermelon, watermelon + bell (for a simultaneous winning), and watermelon + cherry (for a simultaneous winning). The watermelon is a small role of a larger put-out metal number than that at the time of the winning of bells or cherries. The derivation of watermelons for a more put-out metals has a priority, and no return failure occurs while including the case of the simultaneous winning. In the regular bonus, the total value of the determination value numbers of watermelons, watermelons + bells, and watermelons + cherries is 16384. In the regular bonus, the watermelon is always hit including the simultaneous winning with the bell or the cherry.

Description

  The present invention relates to a slot machine, and more particularly, to selection of a small combination display result determined to allow derivation in a special game and provision of game value.

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

  The types of winning combinations include small roles, bonuses, and replays. Here, in the winning of a small role, the player can obtain a profit that a predetermined number of medals are paid out for each type of small role. In the bonus winning, the player can obtain a profit that the next game is shifted to a gaming state advantageous to the player, such as a regular bonus or a big bonus.

  The regular bonus is generally defined as a gaming state that ends when the number of games won and / or the number of games played reaches a predetermined number. The big bonus is generally defined as a gaming state in which a regular bonus is repeatedly provided when a predetermined condition such as derivation of a JACIN symbol is established. Here, in the small role game provided between the regular bonus and the regular bonus as a big bonus, there is a game in which the winning probability of the small role is higher than the normal gaming state.

JP-A-6-327809 (paragraphs 0048 to 0050, FIG. 11)

  However, in the slot machine of Patent Document 1, the types of small roles that are won in the small role game are basically the same as those in the normal gaming state, and even when winning the internal lottery, In some cases, a small role was awarded when only a small number of medals were paid out.

  If you win a small role that only pays out a small number of medals even if you win in this way, you will receive more players than if you win a different type of small role where more medals will be paid out. There was a problem that the profits made would be small. In particular, when the number of games won is determined as an ending condition, winning a small role with a small number of medals is a big disadvantage for the player.

  It is an object of the present invention to provide a slot machine that makes a decision to permit the derivation of a small role display result in order to prevent a player from acquiring a minimum number of gaming values in a special game. To do.

To achieve the above object, a slot machine according to the present invention includes:
A game can be started by setting a predetermined number of bets for one game using a game value (medal), and a variable display device (variable display device 2) that displays a plurality of types of identification information in a variable manner. In the slot machine in which one game is completed by deriving the display result in) and winning can be generated according to the display result derived to the variable display device.
Derivation of a plurality of types of winning display results including a plurality of types of small role display results (watermelon, bell, cherry) accompanied by the addition of the game value before a display result of the variable display device is derived for each game Pre-determining means (step S403, FIG. 14, FIG. 21) for determining whether to allow or not by lottery,
A determination result information setting unit (RAM 112) for setting determination result information (winning flag) according to the determination result of the prior determination unit;
Derivation control means (step S404) for deriving the display result of the variable display device by stopping the variable display of the identification information according to the decision result information set in the decision result information setting means;
Predetermined for a special game (regular bonus) in which, when a predetermined special condition is established, the pre-determining means determines with higher probability than the game in the normal gaming state that the derivation of the small role display result is allowed Special game control means for controlling the period (steps S812 and S814),
The pre-determining means includes
A specific small combination display result to which a predetermined number of game values are given when derived as a display result of the variable display device among the plurality of types of small combination display results when controlled by the special game (Watermelon) is determined with a higher probability than the game in the normal gaming state to permit derivation,
When it is determined that the derivation of other types of small role display results (bell, cherry) having a smaller number of gaming values than the specific small role display result is permitted, the derivation of the specific small role display result (Fig. 5 (b), Fig. 5 (c), Fig. 6: watermelon, watermelon + bell, watermelon + cherry)
It is characterized by that.

  In the slot machine, when it is determined that derivation of a small role display result with a smaller number of game values given than the specific small role display result when controlled by a special game is permitted, It is also determined that the derivation of the combination display result is permitted. In a special game, there is a possibility that at least a specific small combination display result can be derived based on this determination. When it is determined that the derivation of the specified small role display result is permitted, even if the derivation of the small role display result with less gaming value given is permitted, if the specific display result is derived, The player can obtain a predetermined number of game values, and the number of game values to be given is not less than the predetermined number. For this reason, it becomes possible to prevent the player from obtaining only a minimum gaming value in the special game.

  The specific small combination display result is equal to or more than the number of game values given when any other type of small combination display result is derived when the display result of the variable display device is derived. A game value may be given. In this case, the player can obtain the maximum profit by deriving the specific small combination display result in the special game.

In the above slot machine,
The special game control means controls the special game for a predetermined period of time as the special condition is satisfied when a predetermined special game display result (regular bonus, JACIN) is derived as the display result of the variable display device. It is good also as a thing (step S812, S814).

  In this case, the special game is controlled on the basis of an easily understandable display result of the variable display device.

The slot machine is
When a special state display result (big bonus (1), big bonus (2)) predetermined as a display result of the variable display device is derived in the normal gaming state, the player is more advantageous than the normal gaming state. Special state control means (steps S808 and S810) for controlling the gaming state to a special state (big bonus) which is a unique gaming state;
In the special state, it may further include special game determination means (modified example: determined when the start lever is operated) for determining whether or not the game is controlled by the special game. In this case,
The special game control means may start control of the special game as fulfillment of the special condition when it is determined by the special game determination means that the special game is not controlled (deformation) Example: When the big bonus medium flag is set and the regular bonus medium flag is not set, the regular bonus medium flag is set).

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

The slot machine is
When a special state display result (big bonus (1), big bonus (2)) predetermined as a display result of the variable display device is derived in the normal gaming state, the player is more advantageous than the normal gaming state. Special state control means (steps S808 and S810) for controlling the gaming state to a special state (big bonus) that is a special gaming state may be further provided. In this case,
The special game control means starts controlling the special game as establishment of the special condition when controlled to the special state, and starts the control of the special game in the special state for the predetermined period of time. When the game expires and the control of the special game ends, the special game can be resumed as the special condition is satisfied (variation: at the end of the big bonus, at the end of the regular bonus Set regular bonus medium flag).

  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.

The slot machine is
Derivation operation means (stop buttons 12L, 12C, 12R) operated when deriving the display result from the variable display device may be further provided. In this case,
In the derivation control unit, specific small combination determination result information (watermelon winning flag) corresponding to the specific small combination display result is set in the determination result information setting unit, and a winning display result other than the specific small combination display result When the determination result information (bell winning flag, cherry winning flag) corresponding to is set, the specific small combination display result is also the winning display result of the determination result information other than the specific small combination display result. In any case, when the derivation operation means is operated in a derivatable procedure, the specific small combination display result can be derived as a display result of the variable display device.

  In this case, in the special game, when it is determined that the derivation of the specific small combination display result is permitted and the specific small combination determination result information is set, the determination result information corresponding to the other winning display results is set. Even so, as long as the derivation operation means is operated in a procedure capable of deriving the specific small combination display result, the specific small combination display result can be derived without deriving other winning display results. For this reason, in a game in which the gaming state is controlled to a special state, the specific small role display result is always derived as long as the derivation operation means is operated in an appropriate procedure. Can be obtained.

  The derivation control means also displays a winning display result other than the specific small combination display result when the specific small combination determination result information corresponding to the specific small combination display result is set in the determination result information setting means. Regardless of whether or not the corresponding determination result information is set, and regardless of the procedure in which the derivation operation means is operated (FIG. 2), the specific small combination display result is derived as the display result of the variable display device. It can also be made to be.

  In this case, in the special game, when it is determined that the derivation of the specific small combination display result is permitted and the specific small combination determination result information is set, the determination result information corresponding to the other winning display results is set. In this case, the specific small combination display result can always be derived without deriving the other winning display result regardless of the operation procedure of the deriving operation means. For this reason, in the special game, it is not necessary for the player to hold the game, and the game can be advanced easily and quickly. In addition, since the specific small combination display result is always derived, in the special game, the player can surely obtain the maximum profit as long as the deriving operation means is operated in an appropriate procedure.

In the above slot machine,
The pre-determining means may determine that the derivation of the specific small combination display result is allowed only when the special game is controlled (FIG. 5B).

  In this case, the specific small combination display result is derived as the display result of the variable display device only when the special game is controlled. For this reason, the derivation of the specific small combination display result not only increases the profits that the player can obtain in the special game, but also makes it possible to easily show the player that the game is controlled by the special game.

In the above slot machine,
The special game control means controls the special game during a period until the number of games from which the winning display result is derived from the start of the special game reaches a predetermined number of specific games (eight games). (Step S910 (YES) → S911).

  Here, the pre-determining means determines that at least the derivation of the specific small combination display result is permitted when determining that the derivation of any kind of winning display result is permitted, and the specific small combination display result Derivation of any type of winning display result including, may not be allowed. On the other hand, the period during which the special game is controlled is terminated when the number of games from which the winning display results are derived reaches the specific number of games. Thus, the number of games for determining the end of the special game period is not counted. Therefore, the number of game values given in a special game can always be maximized, and the profit obtained by the player is not reduced. Note that the number of game values used for setting the bet amount is not necessarily minimized even when there is a case where it is not determined that derivation of any winning display result including the specified small role display result is permitted in a special game. However, it is possible to obtain the effect of maximizing the number of game values given.

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

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. Corresponds to the determination result information set in the determination result information setting means from a plurality of control patterns (FIG. 9: stop control table) that uniquely specify the display result derived with respect to the number of steps of the stepping motor. Including control pattern selection means (step S704) for uniquely specifying the control pattern;
When the derivation operation unit corresponding to the variable display unit for which the display result has not been derived yet is operated, the control pattern selected for the variable display unit by the control pattern selection unit is the step at the time of operation of the derivation operation unit The display result uniquely specified for the number can be derived as the display result in the variable display unit (step S714).

  In this case, the step of the stepping motor at the time when the derivation operation means is operated for the variable display area 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 areas. The control pattern corresponding to the combination of the game state of the game and the determination result information set in the determination result information setting means is uniquely determined from a plurality of control patterns that uniquely specify the display result derived for the number. The selected control is performed so that the display result is derived to the corresponding variable display area. That is, there is only one control pattern that is applied to one determination result of the prior determination means. For this reason, there is no need to further select any one control pattern from a plurality of control patterns with respect to one determination result of the prior determination means as in the prior art by lottery or the like different from the prior determination means. The control for deriving the display result is not complicated.

The derivation control means includes
In a situation where a display result is derived to at least one of the plurality of variable display sections and a display result is not derived to another variable display section, the variable display section for which the display result has not been derived yet The determination result from a plurality of control patterns (FIG. 9: stop control table) that uniquely specify the display result derived with respect to the number of steps of the stepping motor at the time when the derivation operation means corresponding to the unit is operated Control pattern selection means for uniquely specifying the control pattern corresponding to the number of steps when the corresponding derivation operation means is operated in the variable display section for which the display result has already been derived and the determination result information set in the information setting means (Step S704)
When the derivation operation unit corresponding to the variable display unit for which the display result has not been derived yet is operated, the control pattern selected for the variable display unit by the control pattern selection unit is the step at the time of operation of the derivation operation unit The display result uniquely specified for the number can be derived as the display result in the variable display unit (step S714). In this case,
The control pattern selection means is configured such that when specific information corresponding to the specific small combination display result is set in the determination result information setting means, the number of steps at the time of operation of the derivation operation means indicates the specific small combination display result. When the number of steps is derivable, the control pattern for deriving the specific small combination display result is selected even when the decision result information corresponding to the winning display result other than the specific small combination display result is set. The specific small combination time control pattern selection means is included.

Alternatively, the derivation control means includes
In a situation where a display result is derived to at least one of the plurality of variable display sections and a display result is not derived to another variable display section, the variable display section for which the display result has not been derived yet The determination result from a plurality of control patterns (FIG. 9: stop control table) that uniquely specify the display result derived with respect to the number of steps of the stepping motor at the time when the derivation operation means corresponding to the unit is operated Control pattern selection means (step S704) for uniquely specifying the control pattern corresponding to the combination of the determination result information set in the information setting means and the display result in the variable display unit from which the display result has already been derived,
When the derivation operation unit corresponding to the variable display unit for which the display result has not been derived yet is operated, the control pattern selected for the variable display unit by the control pattern selection unit is the step at the time of operation of the derivation operation unit The display result uniquely specified for the number can be derived as the display result in the variable display unit (step S714). In this case,
The control pattern selection unit is configured such that when the determination result information setting unit sets f specific information corresponding to the specific small combination display result, the number of steps at the operation time of the derivation operation unit is the specific small combination display result. When the determination result information corresponding to the winning display result other than the specific small combination display result is set, the control pattern for deriving the specific small combination display result is determined. The specific small combination time control pattern selection means to be selected is included.

  In these cases, the display result is still derived in any one of the plurality of variable display areas and the display result is not yet derived in the other variable display areas. For the variable display area where the derivation operation means is operated, the variable display area from which the derivation operation means is operated is set in the decision result information setting means from a plurality of control patterns that uniquely identify the display results derived for the number of stepping motor steps. Combination of the determined determination result information and the display result of the variable display area from which the display result has already been derived (or the number of steps when the corresponding derivation operation means is operated in the variable display section from which the display result has already been derived) A corresponding control pattern is uniquely selected, and control is performed to derive a display result in the corresponding variable display area. That is, the combination of the one determination result information and the display result of the variable display area from which the display result has already been derived (or the number of steps when the corresponding derivation operation means is operated in the variable display section from which the display result has already been derived) There is only one control pattern applied to. For this reason, it is not necessary to further select any one of the plurality of control patterns, and the control for deriving the display result of the variable display device is not complicated.

The slot machine is
Numerical data input means (step S503) for inputting numerical data (random numbers for internal lottery) updated within a predetermined range to a determination area predetermined as determination numerical data for each game at a predetermined timing;
Range specifying data storage means for storing a plurality of range specifying data determined so that ranges of determination values for determining that the prior determination means allows the derivation of the plurality of types of winning display results can be specified. (FIG. 6, FIG. 7) may be further provided. here,
The range specifying data storage means is specially accompanied by a transition to a special gaming state that is more advantageous to the player than the normal gaming state by the predetermining means when it is determined that the determination numerical data is included. Overlapping range specification data for specifying a range of determination values that are determined to permit derivation of both a display result and a non-special display result that is a prize display result other than the special display result including the small role display result ( A plurality of range specifying data including regular bonus + cherry, big bonus (1) + cherry, big bonus (2) + cherry) may be stored. In this case,
The pre-determining means allows the derivation of the special display result and the non-special when the numerical value data for determination input to the determination area is included in a determination value range specified by the overlapping range specifying data Both allowances for deriving the display results may be determined.

  In this case, it is determined that the determination numerical data input to the determination area specifies that the special display result derivation is permitted and the non-special display result derivation is permitted. The determination can be made with only one determination as to whether it is included in the range of the determination value specified by the data.

  The special game state is a comprehensive concept of a game state that is more advantageous than the normal game state controlled according to the display result of the variable display device. And a special game controlled by derivation of the special game display result (here, the special game display result becomes the special display result). In the following description, the meaning of the special gaming state is the same.

  For example, as long as the special gaming state is a gaming state controlled in accordance with the display result of the variable display device, in any one or more of the variable display units constituting the variable display device The maximum stop delay time from the operation of the derivation operation means is shortened from the normal gaming state, and the small role display result can be derived irrespective of the determination result of the prior determination means (however, the gaming value is the number of bets) The game state (so-called CT) and the pre-determining means derive the re-game display result (except when it is allowed to derive the re-game display result that allows the next game to be performed without using the setting). A gaming state (so-called RT) in which the probability of determining whether to accept the small role is higher than the normal gaming state, and when the prior determination means has determined that the derivation of the small role display result is permitted, the small role display Fruit may contain operating instructions (or derivation of acceptable types of small prize display result are) player reports the status of the derivation operation means for deriving (so-called AT).

The slot machine is
Numerical data input means (step S1103) for inputting numerical data (random numbers for internal lottery) updated within a predetermined range into a determination area predetermined as determination numerical data at a predetermined timing for each game;
A range of determination values for determining that the pre-determining means allows derivation of a special display result accompanied by a transition to a special gaming state that is more advantageous to the player than the normal gaming state is determined. Special range specifying data storage means for storing the special range specifying data (FIG. 20: bonus table);
A range of determination values for determining that the pre-determining means allows derivation of a non-special display result that is a prize display result other than the special display result including the small combination display result is specified for each type of the prize display result Non-special range specifying data determined to be possible, and at least a part of a range of determination values for determining that the non-special display result is derived is a determination value specified by the special range specifying data. Non-special range specifying data storage means (FIG. 20: small role table) for storing non-special range specifying data included in the range;
Special that carries forward the special decision result information corresponding to the special display result set in the decision result information setting means until the special display result is derived based on the decision to permit the derivation of the special display result A decision carryover means (step S916) may be further provided. here,
The pre-determining means includes
On the condition that the special decision result information is not carried over to the decision result information setting means by the special decision carry-over means (step S1109 (NO)), the determination numerical data is stored in the special range specifying data storage means. Special decision means for deciding whether or not to permit the derivation of the special display result by judging whether or not it is included in the range of the judgment value specified by the specified special range specification data (steps S1110 to S1113) When,
Regardless of whether or not the special decision result information is carried over to the decision result information setting means by the special decision carry-over means (there is no determination step as in step S1109), the numerical value data for determination specifies the non-special range. Determining whether or not the non-special numerical data for determination stored in the data storage means is included in a range of determination values specified by the non-special range specifying data stored in the non-special range specifying data storage means Thus, non-special determination means (steps S1104 to S1107) for determining whether or not to permit the derivation of the non-special display result can be included.

  In this case, it is not necessary to basically change the process when the predetermination means makes a decision depending on whether the decision to allow the derivation of the special display result is carried over, and the derivation of the winning display result is allowed. It is possible to efficiently determine whether or not. In addition, when the decision to allow the derivation of the special display result is carried over, the decision by the special decision means is not required, so that the process is simplified.

The slot machine is
Based on the operation of predetermined setting operation means (setting key switch 92, setting switch 91), a plurality of types of permissible stages (settings) with different probabilities that the predetermination means determines that the derivation of the winning display result is permitted. Value), an allowable stage setting means (steps S201 to S210) for selecting and setting one of the allowable stages,
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 a reset operation, the default permissible stage (usually the permissible stage with the lowest probability of being determined to permit the derivation of the winning display result) is automatically performed. Was to be selected. 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 out data indicating the allowable level stored in the data storage unit when determining whether to permit the derivation of the winning display result, and indicates the read allowable level Permissible stage data determining means (steps S501, S502, S1101, and S1102) for determining whether or not the data is appropriate data indicating an 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 S502 (NO), S1102 (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.

The slot machine is
Based on the operation of predetermined setting operation means (setting key switch 92, setting switch 91), a plurality of types of permissible stages (settings) with different probabilities that the predetermination means determines that the derivation of the winning display result is permitted. Value), an allowable stage setting means (steps S201 to S210) for selecting and setting one of the allowable stages,
Numerical data input means (steps S503 and S1103) for inputting numerical data to be updated within a predetermined range to a predetermined determination area as determination numerical data for each game at a predetermined timing is further provided. I can. In this case,
In the pre-determining means, the determination numerical data input to the determination area is included in a range of a plurality of types of determination values that are predetermined for each unit for performing determination to permit derivation. Is determined to permit the derivation of the winning display result corresponding to the range of the determination value determined to include the determination numerical data (steps S510 and S511),
The slot machine is
Means for storing a plurality of range specifying data determined such that ranges of the plurality of types of determination values can be specified respectively, wherein the first range specifying data among the plurality of range specifying data is the plurality of types A first storage area (regular bonus + cherry, big bonus (1) + cherry, big bonus (2) + cherry, JACIN, watermelon, bell, replay A, replay B), A second storage area (regular bonus, big bonus (1), big bonus) in which second range specifying data different from the first range specifying data among the plurality of range specifying data is stored individually for each type of the permissible stage (2), range specifying data storage means (FIGS. 5 and 6) including cherry) may be further provided.

  Here, the range specifying data storage means stores the range specifying data in common with a plurality of types of allowable stages for any one or more types of winning display results. As described above, the first range specifying data in which the range specifying data is stored in common for a plurality of types of allowable stages requires a small storage capacity for storing the range specifying data.

  In this case, the second storage area includes the same number storage area (regular bonus) for individually storing range specifying data that can specify the same determination value range regardless of the type of the allowable stage, and the allowable stage. Different number storage areas (big bonus (1), big bonus (2), cherry) that individually store range specifying data that can specify different ranges of determination values depending on the type may be included.

  In this way, the second storage area can specify a range of determination values that can specify the range of the same determination value regardless of the type of allowable stage, and a range of determination values that differs depending on the type of allowable stage. And an area for storing various range specifying data. The range specification data determines the probability that the pre-determining means will allow the derivation of each winning display result according to the allowable stage, but this range specification data is subtle for development models. In general, the simulation is performed while adjusting to (the initial range specifying data may be different or may be the same). The appropriate range specifying data obtained as a result of the simulation is applied to a model for mass production.

  Here, even if the range specifying data becomes the same regardless of the allowable stage as a result of performing the simulation while changing the range specifying data according to the allowable stage, such range specifying data remains as it is in the allowable stage. It may be stored separately according to the type. In addition, in the case where different range specifying data is initially stored depending on the type of the permissible stage, if the range specifying data originally registered according to the result of the simulation can be left as it is, it can be stored as it is. . When there is a problem with the range specifying data that is initially registered as a result of the simulation, the range specifying data can be changed according to the allowable stage and stored in the range specifying data storage means. For this reason, since the storage mode of the range specifying data in the development model can be used as it is in the mass production model, development from the initial design stage to the mass production model can be easily performed.

  Note that storing the range specifying data individually according to the types of allowable steps does not necessarily mean that the range specifying data is stored individually for the number of types of allowable steps. If the range specifying data is not stored in common, it is included in this. For example, when there are six types of allowable stages (first stage to sixth stage), the range identification data is allowed in the case where the first to third stages are common and the fourth to sixth stages are common. Depending on the type, it is stored separately.

The slot machine is
A pulse generation circuit (pulse generation circuit 115a) for generating a pulse signal of a predetermined frequency;
An n-bit (n is an integer greater than or equal to 2) array data signal is inverted alternately between the first level and the second level every time a pulse signal is input from the pulse generation circuit, and Each time the level of the (m-1) th bit (m is an integer of 2 or more: m ≦ n) from the lower level is inverted from the first level to the second level, the level of the mth bit from the lower level is changed to the first level. A counter circuit (lower counter 115b, upper counter 115c) that alternately inverts and outputs at two levels;
When a predetermined extraction condition resulting from the player's operation is satisfied for each game, the n-bit array data signal output from the counter circuit is latched, and the latched n-bit array data signal is output in the bit array order. A latch circuit (sampling circuit 116) for outputting without changing
An input means (step S602) for inputting an n-bit array data signal output from the latch circuit as n-bit numerical data without changing the bit array order in a predetermined specific area (general-purpose register 111GR) It can be.

In this case, the slot machine is
Replacing specific bit data of n-bit numeric data input to the specific area with other bit data of the numeric data, and replacing the n-bit replacement numeric data with the exchange, Numerical data input means (steps S603 to S605) for inputting to a predetermined determination area (general-purpose register 111GR) as numerical data for determination (random number for internal lottery) can be further provided.
In the pre-determining means, the determination numerical data input to the determination area is included in a range of a plurality of types of determination values that are predetermined for each unit for performing determination to permit derivation. It is possible to determine that the derivation of the winning display result corresponding to the range of the determination value determined to include the determination numerical data is permitted (steps S509 and S510).

  Here, for the numerical data corresponding to the n-bit array data signal extracted from the counter circuit, the replacement numerical data obtained by replacing the data of the specific bit with the data of the other bits by the replacement means is used as the determination numerical data. It is supposed to be entered. For this reason, the periodicity of the numerical data for determination used for the determination can be lost without varying the determination value used for determining whether or not the derivation of the winning display result is allowed. Thereby, even if the determination value is fixed for each type of the winning display result by using the determination value data indicating the number of the determining values for each type of the winning display result, it is possible to prevent the player from aiming. It becomes like this. Moreover, the periodicity of the numerical data input by the input means can be lost simply by exchanging specific bits, and the processing load does not increase so much without providing a special circuit.

Numerical value data input means (FIG. 22) for inputting the operation result numerical data composed of the upper k bits and the lower j bits after the calculation by the calculation means to a predetermined determination area as determination numerical data. Can also be
In the pre-determining means, the determination numerical data input to the determination area is included in a range of a plurality of types of determination values that are predetermined for each unit for performing determination to permit derivation. It is possible to determine that the winning display result corresponding to the range of the determination value determined to include the determination numerical data is permitted.

  Here, for the upper k bits of the first numerical data corresponding to the n-bit array data signal extracted from the counter circuit, the second numerical data extracted from the numerical value updating means by the numerical value extracting means is used to obtain a predetermined value. The calculation result numerical data obtained by the calculation is input as determination numerical data. Rather than performing the operation on the first numerical data as it is using the second numerical data, the numerical value indicated by the operational numerical data is obtained by performing the operation on the upper k bits of the first numerical data. Becomes larger.

  For this reason, the periodicity of the numerical data for determination used for the determination can be lost without varying the determination value used for determining whether or not the derivation of the winning display result is allowed. Thereby, even if the determination value is fixed for each type of the winning display result by using the determination value data indicating the number of the determining values for each type of the winning display result, it is possible to prevent the player from aiming. It becomes like this. Further, the periodicity of the first numerical data input by the input means can be lost only by extracting the second numerical data from the numerical value updating means and calculating the upper k bits, and without providing a special circuit. , Processing load does not become so large.

In this case, the slot machine also

Calculating means (FIG. 23) for performing a predetermined calculation using data and performing a predetermined calculation using the third numerical data extracted by the second numerical value extraction means for the lower j bits;
Numerical data input means (FIG. 23) for inputting the operation result numerical data consisting of the upper k bits after the operation by the operation means and the lower j bits after the operation to a predetermined determination area as determination numerical data. Can be further equipped,
In the pre-determining means, the determination numerical data input to the determination area is included in a range of a plurality of types of determination values that are predetermined for each unit for performing determination to permit derivation. It is possible to determine that the winning display result corresponding to the range of the determination value determined to include the determination numerical data is permitted.

  Here, the first and second numerical value extraction means respectively apply the first and second numerical value extraction means to the upper k bits and the lower j bits of the first numerical data corresponding to the n-bit array data signal extracted from the counter circuit. Calculation result numerical data obtained by performing a predetermined calculation using the second and third numerical data extracted from the numerical value updating means are input as determination numerical data. The numerical value indicated by the arithmetic result numerical data is not calculated by using the second numerical data as it is for the first numerical data, but by performing an operation on the upper k bits of the first numerical data. Variations increase. The variation is further increased by performing an operation on the lower j bits.

  For this reason, the periodicity of the numerical data for determination used for the determination can be lost without varying the determination value used for determining whether or not the derivation of the winning display result is allowed. Thereby, even if the determination value is fixed for each type of the winning display result by using the determination value data indicating the number of the determining values for each type of the winning display result, it is possible to prevent the player from aiming. It becomes like this. Further, the periodicity of the first numerical data inputted by the input means can be obtained only by extracting the second and third numerical data from the first and second numerical value updating means and calculating the upper k bits and the lower j bits. It can be lost, and the processing load is not so great without providing a special circuit.

  The arithmetic means adds the second numerical data to the upper k bits of the first numerical data, performs subtraction, logical operation (logical sum, logical product, etc.), etc. Arithmetic can be performed. Further, the predetermined calculation can be performed by performing addition, subtraction, logical operation (logical sum, logical product, etc.) using the third numerical data for the lower j bits. An overflow or underflow caused by the result of the operation can be adjusted in the respective ranges of the upper k bits and the lower j bits.

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

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

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

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

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

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

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

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

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

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

  The big bonus (1) is won when a combination of “7-7-7” is arranged in any of the winning lines (five) in the normal gaming state or RT. The big bonus (2) is won when a combination of “BAR-7-7” is arranged in any of the winning lines (five) in the normal 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, a game called a small role game can be played. 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. Further, after the end of the big bonus, the gaming state is controlled to the first RT.

  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 operation timing of the stop buttons 12L, 12C, 12R is not an appropriate timing, the winning combination will not be won.

  JACIN is awarded when a combination of “Replay-Replay-JAC” is arranged in any of the winning lines (5) in the small role game in the big bonus, but in a gaming state other than the small role game, Even if the combination is complete, JACIN won't win. When winning JACIN, the above-mentioned regular bonus is provided in the big bonus, and the regular bonus medium flag is also set in the RAM 112 in addition to the big bonus medium flag. The “replay” for the left and middle reels 3L and 3C and the “JAC” for the right reel 3R are arranged at intervals of 5 frames or less. JACIN won a prize.

  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. . The “bell” for the left and right reels 3L and 3R and the “watermelon” for the inner reel 3C are always arranged at intervals of 5 frames or less. For example, the watermelon can be won regardless of the operation timing of the stop buttons 12L, 12C, and 12R. As will be described later, even when the winning combination with the bell or the cherry is won, since the number of payout medals is larger for the watermelon, it is preferentially derived.

  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. 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.

  Replay A is awarded when a combination of “replay-replay-replay” is arranged in any of the winning lines (five) in the normal gaming state or RT. Replay B is awarded when the combination of “Replay-Replay-Bell” is aligned on any of the winning lines (5) in the first RT. With regular bonuses and big bonuses (small role game and regular bonus), even if these combinations are available, neither Replay A nor Replay B will be awarded. The “replay” for the left and middle reels 3L, 3C and the “replay” or “bell” for the right reel 3R are arranged at intervals of 5 frames or less. Alternatively, when Replay B is won, Replay A or Replay B is always won.

  When a player wins Replay A or Replay B, no medals will be paid out, but the next game can be started without setting the number of bets again. Therefore, it is substantially the same as the case where three medals corresponding to 3) are paid out. When replay B is won in the first RT, the gaming state is further controlled from the first RT to the second RT. Details of the first RT or the second RT will be described later.

  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), bell + watermelon, cherry + watermelon, and watermelon are sequentially read out as a target combination for internal lottery. When the gaming state is a small role game with a big bonus, the regular bonus + cherry, big bonus (1) + cherry, big bonus (2) + cherry, JACIN, bell, cherry are sequentially read out as the internal lottery target roles. . When in normal gaming, regular bonus + cherry, regular bonus, big bonus (1) + cherry, big bonus (1), big bonus (2) + cherry, big bonus (2), bell, cherry, replay A (Normally RT1) is sequentially read out as a target combination of internal lottery.

  When the gaming state is the first RT (shown as RT1 in the figure), regular bonus + cherry, regular bonus, big bonus (1) + cherry, big bonus (1), big bonus (2) + cherry, big bonus ( 2) Bell, cherry, replay A (usually RT1), and replay B are sequentially read out as a target combination for internal lottery. When the gaming state is the second RT (shown as RT2 in the figure), regular bonus + cherry, regular bonus, big bonus (1) + cherry, big bonus (1), big bonus (2) + cherry, big bonus ( 2) Bell, cherry, and replay A (RT2) are sequentially read out as a target combination for internal lottery. The replay A (usually RT1) and the replay A (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. 7C 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-lot games, normal gaming states, and the roles that are 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 normal 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. JACIN is a combination that is subject to internal lottery only in a small role game with a big bonus. The value of the common flag for this role is 1, and a storage address for a common number of determination values is registered regardless of the set value.

  Bells and cherries are internal lotteries in any gaming state other than the regular bonus. For the bell, the common flag is 1, and the storage address of the common number of determination values is registered corresponding to the number of bets regardless of the set value. 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.

  Bell + Watermelon, Cherry + Watermelon, and Watermelon are regular bonus bonuses that are eligible for internal lottery. For Bell + Watermelon, the common flag is 1, and the storage address for the common number of determination values is registered corresponding to the number of bets regardless of the set value. For Cherry + Watermelon and Watermelon, the common flag is 0, and the storage address for the number of determination values is individually registered according to the set value corresponding to the number of bets.

  Replay A (usually RT1) is a role that is subject to internal lottery in the normal gaming state or in the first RT. The common flag for this combination is 1, and a common storage address for the number of determination values is registered regardless of the set value. Replay B is a role that is subject to internal lottery only in the first RT. The common flag for this combination is 0, and a common storage address for the number of determination values is registered regardless of the set value. Replay A (RT2) is a role that is subject to internal lottery only in the second RT. The common flag for this combination is 1, and a common storage address for the number of determination values is registered regardless of the set value.

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

  For example, the address ADD + 0 is an address that is referred to when the target part of the internal lottery is regular bonus + 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 regardless of the set value when the subject combination of the internal lottery is JACIN, and 4431 is acquired as the number of determination values regardless of the set value. The address ADD + 44 is an address that is referred to when the subject of the internal lottery is a bell and the set value is 1-6. The address ADD + 46 is an address that is referred to when the subject combination of the internal lottery is Bell + Watermelon and the set value is 1-6.

  Addresses ADD + 48, ADD + 50, ADD + 52, ADD + 54, ADD + 56, and ADD + 58 are addresses that are referred to when the target drawing of the internal lottery is cherry and the set value is 1-6. Addresses ADD + 60, ADD + 62, ADD + 64, ADD + 66, ADD + 68, and ADD + 70 are addresses that are referenced when the internal lottery is a cherry + watermelon and the set value is 1-6. Addresses ADD + 72, ADD + 74, ADD + 76, ADD + 78, ADD + 80, and ADD + 82 are addresses that are referred to when an internal lottery target role is a watermelon and a set value is 1-6.

  In any case where the set value is 1 to 6, the sum of the determination values of bell + watermelon, cherry + watermelon, and watermelon is 16384. Therefore, when the gaming state is controlled by the regular bonus, including the case of overlapping winning with the bell or cherry, the watermelon will always be won.

  The address ADD + 84 is an address that is referred to when the target part of the internal lottery is Replay A (usually RT1) and the set value is 1-6. Addresses ADD + 86, ADD + 88, ADD + 90, ADD + 92, ADD + 94, and ADD + 96 are addresses that are referred to when the target part of the internal lottery is Replay B and the set values are 1 to 6, respectively, but the same value is registered in each case. Therefore, the winning probability of Replay B in the first RT (0 in other gaming states) is the same regardless of the set value. The address ADD + 98 is an address that is referred to when the target part of the internal lottery is Replay A (RT2) and the set value is 1-6.

  In the first RT, in addition to the replay A (usually the first RT), the replay B lottery is also performed, so the replay winning probability as a whole of the replay A and the replay B is higher than the replay winning probability in the normal gaming state. Get higher. However, with the first RT replay winning probability, the medal payout rate is higher than the normal gaming state, but the medal payout rate exceeds 1 (that is, the internal lottery is more than the number of medals used for setting the bet number). The expected value of the number of medals to be calculated based on the winning probability of the game will not increase). In the second RT, the winning probability of the replay A becomes higher than the overall replay winning probability in the first RT, and the medal payout rate exceeds 1.

  In addition, 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 first RT cannot be said to be a game state advantageous to the player unless considering the transition to the second RT due to the winning of the Replay B, but the game advantageous to the player having a higher medal payout rate than the normal game state. It will be a state. The relationship of the medal payout rates according to the gaming state described here is the same when the set value is any of 1-6.

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

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

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

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

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

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

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

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

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

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

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

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

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

  Next, the first RT and the second RT will be described in detail. The first RT is always shifted to after the big bonus game state ends. The first RT is ended by winning the regular bonus, the big bonus (1), the big bonus (2) or the replay B, or by digesting 50 games from the start of the first RT. When the regular bonus, big bonus (1), big bonus (2), or replay B is won in the first RT, the game state corresponding to each role is controlled, but these roles are not won. If 50 games of 1st RT are digested, it will be controlled to a normal game state.

  Also, the second RT is entered by winning a replay B prize. The first RT is also ended by winning the regular bonus, the big bonus (1) or the big bonus (2), or by digesting 50 games from the start of the second RT. When the regular bonus, big bonus (1) or big bonus (2) is won in the 2nd RT, it is controlled to the gaming state corresponding to each role, but the 2nd RT without winning these roles. If these 50 games are digested, it will be controlled to a normal gaming state. Note that the RAM 112 of the game control board 101 is provided with a first RT counter and a second RT counter that indicate the number of remaining games in the first RT and the second RT, respectively.

  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. 9 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 an address of 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. 10).

  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. 10 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. 10, the area corresponding to each area number is located at the stop reference position (in this embodiment, the lower symbol area in the fluoroscopic window 3). The number of frames to be drawn when the operation of the stop buttons 12L, 12C, 12R is detected at the timing (the timing at which the number of steps from the reel reference position is included in the range of the number of steps of each area number) is set.

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

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

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

  When any of the stop buttons 12L, 12C, and 12R corresponding to the rotating reel is detected effectively, the area number of the stop operation position is based on the number of steps from the reel reference position when the stop operation is detected. And the number of drawn frames corresponding to the area number of the specified stop operation position is acquired by referring to the stop control table of the reel where the stop operation is detected. Then, control is performed to rotate and stop the reel by the number of acquired frames. Specifically, from the number of steps from the reel reference position at the time when the stop operation is detected, the number of steps from the acquired number of drawn frames until 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.

  In addition, in the table index, when multiple types of small roles are won at the same time (such as watermelon + bell in regular bonus), the winning small role (the medal of the medal) is the most advantageous to the player. (The watermelon with a large number of payouts) is determined so that the maximum number of frames can be drawn in the range of 4 frames, and the stop operation position where the most advantageous small part cannot be pulled in the range of up to 4 frames, etc. The address of the table creation data in which the number of drawn frames is determined so as to draw the kind of small role (bell) to the maximum within the range of four frames is stored, and reel stop control is performed. Thus, when the stop operation is performed, if it is possible to align and stop the symbols of the winning combination that is most advantageous to the player among the winning combinations that are won in the drawing range of up to 4 frames on the winning line, If the control is performed to stop them in a uniform manner and the symbol of the most advantageous small part cannot be drawn in the drawing range of up to 4 frames on the winning line, it will be elected in the drawing range of up to 4 frames on the winning line. If you can stop the symbols of other types of small roles that have been aligned, control will be performed to stop them. If the symbol is not selected, the symbol will be stopped in the range of 4 frames. Will be performed. That is, in such a case, priority is given to the control of aligning the winning combination with the most advantageous winning combination for the player on the winning line, and only when the winning advantageous winning combination cannot be drawn. It becomes possible to win other types of small roles.

  Next, commands that the CPU 111 of the game control board 101 transmits to the effect control board 102 will be described. The CPU 111 sends various commands according to the progress of each game, but a winning status notification sent after the internal lottery is performed as a command necessary for performing the effects described in this embodiment. There are a command, a winning information command sent after the display result is derived to the variable display device 2, and a gaming state command sent after the end of the game and before shifting to the next game.

  The winning status notification command indicates the setting status of the winning flag in the RAM 112. The winning information command indicates the presence / absence of a winning and the type of winning. The gaming state command is a gaming state to be applied in the next game (usually, the first RT, the second RT, a regular bonus (until a small bonus game in a big bonus or not), a small bonus game in a big bonus) Is shown.

  The CPU 121 of the effect control board 102 performs various effects based on the commands sent from the CPU 111 of the game control board 101 as described above. As an effect performed by the control of the CPU 121, an effect performed on the liquid crystal display 4 in particular includes a notice and a notice of winning of the regular bonus, the big bonus (1) or the big bonus (2).

  Here, the bonus notification is a definite notification that the regular bonus, the big bonus (1), or the big bonus (2) is won, and is performed only when these roles are won. Bonus notice is a notice that there is a possibility that a regular bonus, a big bonus (1) or a big bonus (2) may be won, and it is not won even when these roles are won Although it is sometimes done, there is a higher probability that it will be done when these roles are won.

  When the game state is a big bonus or a regular bonus, the regular bonus, the big bonus (1) or the big bonus (2) is not won in the first place, so no bonus announcement or bonus notice is performed. Even in the normal gaming state or RT, when a bonus notification has already been made, no further bonus notification or bonus notice is performed. When the bonus notification is not yet performed in the normal gaming state or RT, a notice / notice determination lottery for determining whether to perform the bonus notification or the bonus advance notice is performed.

  When the notice determination lottery is won, a notice flag is set in the RAM 122 and a bonus notice is given on the liquid crystal display 4. Once the bonus notification is made at the start of any game, the bonus notification is continued until a regular bonus, a big bonus (1), or a big bonus (2) is won. When the notice determination lottery is won, a notice flag is set in the RAM 122 and a bonus notice is given on the liquid crystal display 4. The bonus announcement is made at the start of the game, and is ended only for the game regardless of whether the regular bonus, the big bonus (1) or the big bonus (2) is won.

  In the second RT, the notice determination lottery is not performed, but only the notice determination lottery is performed. That is, the bonus notification is not performed while the gaming state is in the second RT, except when the replay B is won in the state where the bonus notification is performed in the first RT and the game proceeds to the second RT. When a regular bonus, a big bonus (1), or a big bonus (2) is won in the second RT, a bonus notification is made in the game in which the second RT has ended.

  The regular bonus, big bonus (1) or big bonus (2) will not be won at the same time as the bell or replay. If it was lost in the previous game when winning the bell or replay, it is predicted that the regular bonus, big bonus (1) or big bonus (2) will not be won even if a bonus notice is given Will be. Accordingly, the bonus notice may be determined on the condition that the player has not won the bell or replay. Further, it may be determined that the bonus advance notice is made on the condition that the replay derived in preference to the regular bonus, the big bonus (1) or the big bonus (2) is not won.

  In order to make it possible for the CPU 121 of the effect control board 102 to determine that the bonus notification or the bonus advance notice is being performed, the RAM 122 has a notification flag indicating that the bonus notification is being performed, and a bonus advance notice. There is an area for setting a notice flag indicating that the In addition, the RAM 122 stores the winning status of each combination indicated by the winning status notification command received from the game control board 101, an area for storing winning information indicated by the winning information command, and the gaming status indicated by the gaming status command. These areas (for two games) are also provided.

  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 0 and the set value work 112-4 is rewritten to 0) (step S109), the prohibition of interruption is canceled (step S110), and the process proceeds to the setting change process shown in FIG. 11 (step S111). Then, after the setting change process is completed, the game can be progressed and the process proceeds to the game control process.

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

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

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

  FIG. 12 is a flowchart showing in detail the RAM abnormality error process executed by the CPU 111 of the game control board 101. In the RAM abnormality error process, the game number display unit 51 is controlled to display the RAM abnormality error code on the game number 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 game number display unit 21, the process proceeds to a loop process in which no process is performed, so that the progress of the game is disabled.

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

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

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

  FIG. 13 is a flowchart showing a game control process performed by the CPU 111 of the game control board 101 for each game. This process is also executed after the power is turned on and a predetermined boot process is performed, or immediately after the setting is changed by operating the setting switch 91. When the process of one game is started, 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). Here, when the gaming state is a regular bonus (including that provided during the big bonus), if the bet number is set to 1 (the bet number larger than this is not set), the start lever 11 is activated. Become. In other game states, the start lever 11 becomes effective after 3 is set as the bet number. Further, if the player has won a replay in the previous game, the same bet number (3 in this embodiment) as the previous game is automatically set by the replay game flag (the replay game flag is erased at this stage). The start lever 11 becomes effective as it is.

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

  When the lottery process is completed, a reel rotation process is performed (step S404). In the reel rotation process, the reel motor is operated on the condition that a predetermined time (for example, 4.1 seconds) has elapsed from the start of rotation of the reels 3L, 3C, and 3R in the previous game. 3ML, 3MC, and 3MR are driven to start rotation of all the left, middle, and right reels 3L, 3C, and 3R. When predetermined conditions (detection of the reference position by the reel sensors 3SL, 3SC, 3SR after the rotation speed reaches a certain speed) from the start of rotation of the reels 3L, 3C, 3R are satisfied, the stop buttons 12L, 12C, 12R Is enabled. Thereafter, when the stop buttons 12L, 12C, and 12R are operated by the player, the driving of the reel motors 3ML, 3MC, and 3MR is stopped according to the setting state of the winning flag, and the rotation of the reels 3L, 3C, and 3R is stopped. . 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 lottery process in step S403 will be described in detail. FIG. 14 is a flowchart showing in detail the lottery process executed by the CPU 111 in step S403. In the lottery process, the set value stored in the set value work 112-4 of the RAM 112 is read (step S501), and 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 S502). 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 numbers for lottery are processed into random numbers for storage in the internal random number storage area of the RAM 112 (step S503). Details of the random number acquisition process will be described later.

  Next, corresponding to 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 S504). Next, the common flag setting status registered in the role-specific table of FIG. 5C for the read lottery target role is acquired (step S505). As a result, it is determined whether the common flag is set (step S506).

  If the common flag is set, the number of determination values stored in the address registered in the role-specific table of FIG. 5C is acquired for the read lottery target role (step S507). Then, the process proceeds to step S509. If the common flag is not set, the setting value set in the RAM 112 is read, and the number of determination values stored in the address registered in the role-specific table corresponding to the setting value read for the lottery target role Is acquired (step S508). Then, the process proceeds to step S509.

  In step S509, the number of determination values acquired in step S507 or S508 is added to the internal lottery random number value stored in the determination area of the RAM 112, and the addition result 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 S510).

  If no overflow has occurred, it is determined whether there is a combination that has not yet been processed among the lottery targets in the gaming state (step S511). If there is something that has not yet been processed, the process returns to the processing of step S504, and the processing is continued with the next lottery target registered in the winning combination table by gaming state as the processing target. If there is nothing not to be processed, the process proceeds to step S520.

  If an overflow occurs, it is determined whether or not the lottery target combination read in the previous step S504 is any of regular bonus + cherry, big bonus (1) + cherry or big bonus (2) + cherry ( Step S512). 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, first, it is determined whether or not the current gaming state is a small role game (step S513). If it is not during the small role game, 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 S514). If none of the regular bonus winning flag, big bonus (1) winning flag and big bonus (2) winning flag is set, the regular bonus winning flag, big bonus (1) winning flag or The big bonus (2) winning flag is set in the RAM 112, and the cherry winning flag is set in the RAM 112 (step S515). Then, the process proceeds to step S520.

  If the current gaming state is a small role game in step S513, or if the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is already set in the RAM 112 in step S514 Only the cherry winning flag is set in the RAM 112 (step S516). Then, the process proceeds to step S520.

  In step S512, if 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 S517). 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 it is present (step S518).

  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 S520. In step S517, whether the lottery is a regular bonus, a big bonus (1), or a big bonus (2), a regular bonus winning flag, a big bonus (1) winning flag, and a big bonus (2) winning flag in step S518 If neither of these is set, the winning flag of the lottery object combination is set in the RAM 112.

  Here, if the lottery subject is a bell + watermelon, the bell winning flag and the watermelon winning flag are set in duplicate, and if it is cherry + watermelon, the cherry winning flag and the watermelon winning flag are set in duplicate. 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 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 S519). . Then, the process proceeds to step S520.

  In step S520, a winning status notification command is generated according to the setting status of the winning flag in the RAM 112, and is transmitted to the effect control board 102. Then, the lottery process is terminated, and the process returns to the flowchart of FIG.

  Next, the random number acquisition process in step S503 will be described in detail. FIG. 15 is a flowchart showing in detail the random number acquisition process executed by the CPU 111 in step S503. In the random number acquisition process, first, an interrupt to the CPU 111 is prohibited (step S601). Next, a sampling command is output to the sampling circuit 116, the random number generated by the random number generation circuit 115 is latched, and the value of the latched random number is input from the I / O port 114 and extracted. The random number value extracted from the random number generation circuit 115 is stored in the general-purpose register 111GR (step S602).

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

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

  Next, the work initialization code at the time of starting the rotation of the reel motor is set in the register, and the rotation of the reel is started (step S703). 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 S704), and the work initialization code at the completion of stop preparation is set in the register (step S705). Thereby, the operation of the stop buttons 12L, 12C, and 12R becomes valid.

  Next, it is determined whether or not any valid operation of the stop buttons 12L, 12C, and 12R has been detected (step S706). 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 S707). 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 during which medal payout is permitted) (steps S708 and S709). If no error is determined in steps S707 to S709, the process returns to step S706.

  If it is determined in step S708 that an insertion error has occurred, or if it is determined in step S709 that a payout error has occurred, an error code indicating the input / discharge error during reel rotation is set in the register (step S709). In step S710, the process proceeds to predetermined error processing (step S711). If the error is released, the process returns to step S706 again.

  If it is determined in step S707 that a reel rotation error has occurred, an error code indicating the reel rotation error is set in the register (step S712), and the process proceeds to a predetermined error process (step S713). Along with this, the rotation of the reels 3L, 3C, 3R is also temporarily stopped. If the error is released, the process returns to step S703 again, and the rotation of the reels 3L, 3C, 3R is resumed.

  If the operation of the stop buttons 12L, 12C, 12R is detected in step S706, the reel motor (any one of 3ML, 3MC, 3MR) corresponding to the operated stop button from the reel reference position at that time. The number of steps (the number of steps at the stop operation position) is acquired and set to the work corresponding to the stop reel (step S714). Then, it waits until rotation of the reel (any one of 3L, 3C, 3R) corresponding to the operated stop button stops (step S715).

  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 S716). If the rotation of the reels 3L, 3C, 3R is not stopped, the process returns to step S704. If the rotation of all the reels 3L, 3C, 3R is stopped, the reel rotation process is terminated and the process returns to the flowchart of FIG.

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

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

  If the symbol combination of the combination is complete, a winning flag for the combination is set in the RAM 112 (step S803), and the process proceeds to step S804. If the symbol combination of the combination is not complete, the process proceeds to step S804 as it is. If RT symbols are available in the normal gaming state, the RT winning flag will be set in the RAM 112. However, if the RT symbols are available but in other gaming states, the RT winning flag is set. Never happen.

  In step S804, it is determined whether there is a combination that has not yet been determined as a winning determination among the combinations corresponding to the gaming state. If there is a winning combination that has not yet been determined for winning, the process returns to step S801, and the next winning combination corresponding to the gaming state is read out.

  If all of the winning combinations corresponding to the gaming state are targeted for winning determination, it is next determined whether or not the Replay A winning flag is set according to whether or not the Replay A winning flag is set in the RAM 112 (step S805). If Replay A has been won, a replay game flag is set in the RAM 112 (step S806). The replay game in-progress flag is deleted when the bet number is automatically set in the next game. Then, the process proceeds to step S818.

  If the replay A is not won, it is determined whether or not the big bonus (1) is won according to whether or not the big bonus (1) winning flag is set in the RAM 112 (step S807). If the big bonus (1) has been won, the big bonus medium flag is set in the RAM 112 and the big bonus (1) winning flag set in the RAM 112 is erased. Further, the values of the first RT counter and the second RT counter in the RAM 112 are both initialized to 0 (step S808). Then, the process proceeds to step S818.

  If the big bonus (1) has not been won, whether or not the big bonus (2) has been won is determined based on whether or not the big bonus (2) winning flag is set in the RAM 112 (step S809). If the big bonus (2) is won, the big bonus medium flag is set in the RAM 112 and the big bonus (2) winning flag set in the RAM 112 is deleted. Further, the values of the first RT counter and the second RT counter in the RAM 112 are both initialized to 0 (step S810). Then, the process proceeds to step S818.

  If the big bonus (2) has not been won, whether or not the regular bonus has been won is determined based on whether or not the regular bonus winning flag is set in the RAM 112 (step S811). If the regular bonus is won, the regular bonus medium flag is set in the RAM 112 and the regular bonus winning flag set in the RAM 112 is erased. Further, the values of the first RT counter and the second RT counter in the RAM 112 are both initialized to 0 (step S812). Then, the process proceeds to step S818.

  If the regular bonus has not been won, it is determined whether or not a JACIN win has been made based on whether or not the JACIN win flag is set in the RAM 112 (step S813). If a JACIN prize has been won, the regular bonus flag is set in the RAM 112 and the JACIN winning flag set in the RAM 112 is erased (step S814). Then, the process proceeds to step S818.

  If no JACIN winning has been made, it is determined whether or not Replay B has been won depending on whether or not the RT winning flag is set in the RAM 112 (step S815). If Replay B has been won, 51 is set as the initial value of the second RT counter in the RAM 112. Here, to set 51 as the initial value, the value of the second RT counter is decremented by 1 in step S915 (described later) until the next game is started. This is to secure 50 games as the number of games. In addition, since the first RT is finished by winning the replay B, the value of the first RT counter in the RAM 112 is initialized to 0 (step S816). Further, a replay game in-progress flag is set in the RAM 112 (step S817). Then, the process proceeds to step S818. If no replay B winning is made, the process proceeds to step S818.

  In step S818, winning information indicating the type of winning combination based on the winning flag set in the RAM 112 (however, if the game is lost, the winning flag is not set) and the number of medals to be paid out in accordance 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. 18 is a flowchart showing in detail the payout process executed by the CPU 111 in step S406. In the payout process, it is determined whether or not there is a small prize winning accompanied by a medal payout depending on whether or not a winning flag of watermelon, bell, or cherry is set in the RAM 112 (step S901). If the small role is not won, the process proceeds to step S903 as it is.

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

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

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

  When the total number of paid-out medals exceeds 465, the big bonus medium flag set in the RAM 112 is erased, and the counter value for counting the total number of paid-out medals is initialized to 0 (step S906). ). Since the gaming state is controlled to the first RT after the end of the big bonus, 50 is set as the initial value of the first RT counter of the RAM 112 (step S907). The reason why 50 is set as the initial value unlike step S816 is that the process in step S913 described later is not performed in the game in which this step is executed. Then, the process proceeds to step S911.

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

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

  If the number of winning games in the regular bonus is 8 or the number of digested games in the regular bonus is 12, the process proceeds to step S911. If the number of winning games in the regular bonus is not eight and the number of digested games in the regular bonus is not twelve, the process proceeds to step S916. In step S911, the regular bonus flag set in the RAM 112 is erased, and the values of the counters for counting the number of digest games and the number of winning games in the regular bonus are both initialized to zero. Then, the process proceeds to step S916.

  If the game state of the game is not a regular bonus in step S908, it is determined whether or not the value of the first RT counter in the RAM 112 is 0 (step S912). If the value of the first RT counter is not 0, the value of the first RT counter is decremented by 1 (step S913), and the process proceeds to step S916. If the value of the first RT counter is 0, it is further determined whether or not the value of the second RT counter in the RAM 112 is 0 (step S914). If the value of the second RT counter is not 0, the value of the second RT counter is decremented by 1 (step S913), and the process proceeds to step S916. If the value of the second RT counter is 0, the process proceeds to step S916 as it is.

  In step S916, if the watermelon winning flag, the bell winning flag, the cherry winning flag, the replay winning flag, and the JACIN winning flag are set in the RAM 112, these are deleted. The big bonus (1) winning flag, the big bonus (2) winning flag, and the regular bonus winning flag are not erased here and are carried over to the next game. If a winning flag is set in the RAM 112 in step S803, it is deleted.

  Next, based on the big bonus medium flag and the regular bonus medium flag in the RAM 112 and the value of the RT counter, a game state command indicating a game state applied in the next game is generated and transmitted to the effect control board 102. (Step S917). Then, the payout process is terminated, and the process returns to the flowchart of FIG. Here, when returning to the flowchart of FIG. 13, the process in the current one game ends.

  In the repetition of the game as described above, the CPU 111 of the game control board 101 shifts the game state between the normal game state, the first RT, the second RT, the big bonus, and the regular bonus, and the progress of the game In response, a 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 including a bonus notice and a bonus notice based on a 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.

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

  If the received command type is the winning status notification command transmitted in step S520, the setting status of the winning flag indicated by the received winning status notification command is further stored in a predetermined area of the RAM 122 (step S1003). ). Next, it is determined whether or not the gaming state saved in the RAM 122 in the previous game (that is, the gaming state in the current game) indicates a big bonus or a regular bonus (step S1004).

  If neither the big bonus nor the regular bonus exists, it is determined whether or not a bonus notification has already been made based on whether or not a notification flag is set in the RAM 122 (step S1005). If a bonus notification has been made, the process returns to step S1001. Even when there is a big bonus or a regular bonus in step S1004, the process returns to step S1001.

  If the bonus notification is not performed in step S1005, for example, a random determination lottery performed by the software random number function is performed, and a notification / notice determination lottery for determining whether to perform the bonus notification and whether to perform the bonus advance notice is performed. The decision to announce the bonus is based on the premise that either the regular bonus, the big bonus (1) or the big bonus (2) is won, but the gaming state is controlled by the second RT. If so, no bonus announcement will be made. That is, when the gaming state is controlled to the second RT, only the notice determination lottery for determining whether or not to give a bonus notice is performed (step S1006).

  Next, it is determined whether or not it has been decided to make a bonus notice or a bonus notice in this notice / notice decision lottery (step S1007). If it is determined that neither bonus announcement nor bonus notice will be performed, the process returns to step S1001. When it is decided to give a bonus notice or bonus notice, a bonus notice or bonus notice is given on the liquid crystal display 4 in the manner determined by the lottery (step S1008).

  Next, it is determined whether a bonus notification or a bonus notice was made (step S1009). If it is a bonus notification, a notification flag is set in the RAM 122 (step S1010), and the process returns to step S1001. If it is a bonus notice, a notice flag is set in the RAM 122 (step S1011), and the process returns to step S1001.

  If the received command type is the winning information command transmitted in step S818, the winning information indicated by the received winning information command is stored in the RAM 122 (step S1012). Here, when a winning combination of some kind has occurred, an image is displayed on the crystal display 4 in a manner corresponding to the type of the winning combination, and a sound is output from the speakers 7L, 7R, 7U. An effect determined according to the type of winning combination is performed, such as turning on the effect LEDs 75A to 75M and turning on the reel lamp 3LP (step S1013).

  Next, it is determined whether or not a bonus notification is performed on the liquid crystal display 4 depending on whether or not a notification flag is set in the RAM 122 (step S1014). If a bonus notification has been made, it is determined whether the received winning information command indicates a winning of a regular bonus, a big bonus (1), or a big bonus (2) (step S1015).

  If the winning of the regular bonus, the big bonus (1) or the big bonus (2) is indicated, the bonus notification is terminated here, and the notification flag set in the RAM 122 is erased (step S1016). Then, the process returns to step S1001. If no regular bonus, big bonus (1), or big bonus (2) has been won in step S1015, the process directly returns to step S1001.

  If the bonus notification is not performed in step S1014, it is determined whether the bonus notification is being performed on the liquid crystal display 4 depending on whether the notification flag is set in the RAM 122 (step S1017). If a bonus advance notice has been performed, the bonus advance notice is terminated here, and the advance notice flag set in the RAM 122 is erased (step S1018). Then, the process returns to step S1001. If no bonus announcement has been made, the process directly returns to step S1001.

  If the received command type is the gaming state command transmitted in step S917, first, the gaming state indicated by the received gaming state command is stored in the RAM 122. Here, since the RAM 122 has an area for storing the past two game states, the previous game state is shifted to store the game state indicated by the currently received game state command (step S1019).

  Next, the gaming state saved in the current game is compared with the gaming state saved in the previous game, and it is determined whether or not the second RT has ended for the current game only (step S1020). If the 2nd RT has not ended with the current game, that is, if the 2nd RT has not already been reached since the previous game, or if the 2nd RT continues in the next game, the process continues to step S1001. Return.

  If the 2nd RT has been completed for the current game, it is determined whether or not the winning status stored in step S1003 indicates winning of the regular bonus, the big bonus (1) or the big bonus (2) ( Step S1021). If any of the regular bonus, the big bonus (1), and the big bonus (2) is not indicated, the process directly returns to step S1001.

  If the winning of the regular bonus, the big bonus (1), or the big bonus (2) is shown, the liquid crystal display 4 gives a bonus notification. Further, a notification flag indicating that the bonus notification has already been performed is set in the RAM 122 (step S1022). Then, the process returns to step S1001.

  If the received command type is another command, processing corresponding to the type of each command (the details are omitted because it is not related to the present invention) is executed (step S1023). Thereafter, the process returns to step S1001.

  As described above, in the slot machine 1 according to this embodiment, the first RT is controlled after the big bonus is completed. When controlled to the first RT, the winning probability as a whole of replay accompanied by replay is increased. This is based on the fact that a replay B winning opportunity is also given that involves controlling the gaming state to the second RT that cannot be won in the normal gaming state. Then, the game state is controlled from the first RT to the second RT by deriving the replay B. In other words, since there is a difference in the presence or absence of the opportunity to be controlled by the second RT depending on whether it is the normal gaming state or the first RT, the opportunity to be controlled by the second RT does not become monotonous, Interest can be improved.

  In addition, the first RT and the second RT are both common in terms of RT that increases the winning probability of the entire replay as compared to the normal gaming state, but the medal payout rate in the first RT is 1 or less. The medal payout rate in the second RT exceeds 1. In this way, there are two types of games with different profits that the player can obtain even in the same RT, so that the game content can be varied a lot, and the interest of the game can be further improved. Further, when controlled to the first RT, the probability of winning (winning) in Replay B increases, but when the Replay B is won, the gaming state is controlled to the second RT. In the 2nd RT, unlike the 1st RT, the medal payout rate will exceed 1. Therefore, the player's expectation for the winning (winning) of the replay B in the 1st RT can be increased, and the interest of the game is further enhanced. Can be improved.

  The first RT controlled after the end of the big bonus is continued for 50 games unless a regular bonus, a big bonus (1), a big bonus (2), or a replay B is won. The second RT is continued for 50 games unless a regular bonus, a big bonus (1) or a big bonus (2) is won. Thus, since the number of continuing games of the second RT is not less than the number of continuing games of the first RT, the RT does not end earlier due to the winning of the replay B, and the winning of the replay B in the first RT (winning) ) Against the player's expectations.

  Further, in the slot machine 1 according to this embodiment, it is definite that the regular bonus, the big bonus (1) or the big bonus (2) is won as the effect by the image displayed on the liquid crystal display 4. A bonus notice for notifying the player, and a bonus notice for notifying that there is a possibility of winning the regular bonus, the big bonus (1), or the big bonus (2). By this bonus notification or bonus announcement, the player's expectation for winning the regular bonus, the big bonus (1) or the big bonus (2) can be increased, and the interest of the game can be improved.

  In addition, after the big bonus ends, the gaming state is controlled to the first RT. In the first RT, not only Replay A but also Replay B may be won, so the replay winning probability is high and the medal payout rate is higher than in the normal gaming state. The first RT continues for 50 games, but if the regular RT, big bonus (1), big bonus (2) or replay B is won before the first RT is consumed, the first RT When the game is finished, the game state is controlled according to each combination. In particular, when winning a replay B, the replay winning probability is further increased, and the medal payout rate is controlled to the second RT which exceeds 1.

  When the gaming state is the 2nd RT, the 2nd RT ends even if the regular bonus, the big bonus (1) or the big bonus (2) is won, except when the bonus announcement is made during the 1st RT Bonus announcements will not be made. In the first RT, Replay A or Replay B is won with a relatively high probability, but both are unmissable roles, and the combination of symbols is different only on the right reel 3R, so it is not Replay A but Replay B. The player often misses the winning. When controlled to the second RT, the winning probability of Replay A will be higher than the winning probability of the entire replay in the first RT, so if the number of games is digested to some extent, the player is controlled to the second RT I have a clue. However, if the Replay B winning is missed, the player does not know when the second RT ends.

  Therefore, it is possible to give the player a sense of expectation for the continuation of the second RT, and to improve the interest of the game. However, the second RT continues for 50 games unless a regular bonus, a big bonus (1) or a big bonus (2) is won. In other words, since the second RT does not end only by winning the regular bonus, the big bonus (1) or the big bonus (2), the player does not lose the profit of the second RT, which is the duration of 50 games. .

  In addition, when the gaming state is the 2nd RT, a bonus announcement is newly made even if the regular bonus, the big bonus (1) or the big bonus (2) is won, unless the bonus has already been announced at the 1st RT. It will never be. This makes it possible to give the player the benefit of 50 games in the second RT without giving extra information to the player. On the other hand, when 50 games are consumed in the second RT, if a regular bonus, a big bonus (1) or a big bonus (2) is won, a bonus notification is always made. As a result, in the game in which the second RT ends, the player can be given a sense of expectation for winning the regular bonus, the big bonus (1), or the big bonus (2), and the fun of the game can be further improved. .

  If the regular bonus, the big bonus (1), or the big bonus (2) is won when the gaming state is in the first RT, a bonus notification may be issued unlike the case of the second RT. In the first RT, even if the replay winning probability is higher than the normal gaming state, the medal payout rate does not exceed 1, so the regular bonus, big bonus (1) or big bonus (2) based on the bonus announcement ) In the early stage, and the player can select a game in which a regular bonus or a big bonus is obtained. However, even if the bonus announcement is made at the first RT, the player does not dare to win the regular bonus, the big bonus (1) or the big bonus (2), but waits for the second RT to be controlled by the Replay B controlled by the second RT. After gaining profits, you can also choose to get regular bonuses and big bonus profits. In this way, the strategy of the game is enhanced, so that the interest of the game is greatly improved.

  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 in a big bonus (including a small role game and a regular bonus), neither Replay A nor Replay B is determined as an internal lottery target role, and therefore, 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.

  In addition, the display mode of JACIN for shifting the gaming state from the small role game to the regular bonus in the big bonus is configured by a combination of “Replay-Replay-JAC” and is not used as a display mode of other roles. It is. For this reason, the relationship between the display mode derived to the variable display device 2 and the winning combination is clarified, and the game is easy to understand for the player.

  The rotation of the reels 3L, 3C, and 3R is stopped within the range of the maximum stop delay time of 190 milliseconds after the operation of the stop buttons 12L, 12C, and 12R is detected by the stop switches 42L, 42C, and 42R. Since 4 frames can be drawn during this period, the symbol to be stopped can be selected from the range of 5 frames. When JACIN, Bell, Watermelon, Replay A, or Replay B is won, this will not be missed.

  In particular, when the gaming state is controlled by a regular bonus, including the case of overlapping winning a bell or cherry, the watermelon is won with a probability of 100%. The watermelon is a role that cannot be missed, and is a role that is preferentially derived even in the case of duplicate winning with a bell or cherry. In addition, watermelon is a role with a larger number of medals at the time of winning than bells and cherries, and when the gaming state is controlled by a regular bonus (including when it is controlled by a regular bonus in a big bonus) It is a role that can only be won, that is, it is impossible to win.

  As a result, when the game state is controlled to the regular bonus, the player does not have to push at all, and the game can be easily advanced. Since there is no game that does not win with a regular bonus, the amount of medals used to set the bet amount can be minimized. In addition, since the number of winning games as a regular bonus ending condition when winning a role other than watermelon is not counted, the number of medals to be paid out in one regular bonus is the maximum calculated number (15 × 8). = 120), and the player can always receive a payout of 120 medals for each regular bonus ((15-1) × 8 = net increase of 112 medals). .

  Further, when the gaming state is controlled to the regular bonus, since the watermelon is always derived as the display result of the variable display device 2, it is determined that the regular bonus is also controlled by the display result of the variable display device 2. It will be easy for the person to understand. On the other hand, in a normal gaming state other than the regular bonus or in a small role game, a watermelon will not be won, and the player's medal increases by one small role winning will not increase, so in a gaming state other than the regular bonus, The so-called change of the ball does not become too large.

  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 particular, the number of replay B determination values in the first RT is stored at different addresses depending on the set value, but the same value is registered at the address corresponding to any set value. For this reason, in the slot machine 1 according to this embodiment, the replay winning probability in the first RT, that is, the rush probability in the second RT, is made the same regardless of the set value. By simply changing the specification to a different value, it is possible to easily develop a new slot machine in which the winning probability of the second RT is different for each set value.

  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 normal gaming state, the number of determination values in the first RT or the second RT is registered with the regular bonus, the big bonus (1), the big bonus (2), and the cherry as a lottery target. . 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 part of “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 that is one of the lottery targets, the regular bonus is still maintained. There is a possibility that any of a winning flag, a big bonus (1) winning flag, and a big bonus (2) winning flag is set. Therefore, even when winning the “Cherry” small role, the player can expect the regular bonus, the big bonus (1), or the big bonus (2) to be won, improving the fun of the game. Can be made.

  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. In other words, even when it is not possible to properly determine whether or not to win the winning combination in the internal lottery, the game may be played based on the setting value selected and set based on the setting change operation. Since it is secured, 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.

  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 first RT is always controlled after the end of the big bonus. However, after the big bonus is over, it is not necessarily controlled to the first RT, it is controlled to the first RT when winning a predetermined RT lottery, and when it is out of the lottery, it is controlled to the normal gaming state It is good. Also, for example, when the big bonus controlled based on the big bonus (1) winning is finished, the control is made to the first RT, but the big bonus controlled based on the big bonus (2) winning is finished. In such a case, the normal gaming state may be controlled without controlling to the first RT. It is good also as what controls to 1st RT after completion | finish of a regular bonus.

  Further, at least the end of the big bonus or the regular bonus is not a condition for controlling to the first RT, but may be controlled to the first RT when other conditions are satisfied. For example, the first RT may be controlled on condition that a specific display result (RT symbol) is derived as the display result of the variable display device 2 in the normal gaming state. This RT symbol may apply a display mode of a small role such as cherry, or may apply an output that is derived only when a small role such as cherry is missed. A third replay symbol different from Replay A and Replay B may be applied as the RT symbol.

  In the above embodiment, Replay B with control to the second RT is a role that is subject to internal lottery only when the gaming state is controlled to the first RT, and is controlled to the second RT only from the first RT. It never happened. On the other hand, even in the normal gaming state, the replay B with the control to the second RT may be won. The winning probability of the entire replay is 1RT or less in the normal gaming state, but here, the winning probability of Replay B in the normal gaming state needs to be lower than the winning probability of Replay B in the first RT. The winning probability of Replay B in the gaming state is preferably lower than the winning probability of the regular bonus, the big bonus (1), and the big bonus (2).

  Further, even when the gaming state is controlled to the second RT, the replay B may be used as an internal lottery target. The winning probability of Replay B in the second RT may be lower than the first RT, the same as the first RT, or higher than the first RT. Here, when the replay B is won and won in the second RT, only the replay game flag can be set and the value of the second RT counter can be left as it is. However, 51 can be newly set as the initial value of the second RT counter regardless of the value of the second RT counter at that time. That is, the Replay B winning in the second RT has the meaning of extending the number of continuing games in the second RT.

  In the above embodiment, the number of continuing games of the first RT is 50 games (however, until the regular bonus, big bonus (1), big bonus (2) or replay B is won), and the number of continuing games of the second RT. There were also 50 games (until the regular bonus, big bonus (1) or big bonus (2) was won). However, the number of continued games in the first RT and the second RT is not limited to 50 games. The number of continuing games in the first RT and the number of continuing games in the second RT may be different from each other. Both the number of continuing games of the first RT and the number of continuing games of the second RT may not be fixed in advance, but may be variable numbers of games determined by lottery, for example. In this case, it is preferable that the expected value of the number of games of the second RT determined by the lottery is greater than or equal to the expected value of the number of games of the first RT determined by the lottery.

  In the above embodiment, in the first RT, the medal payout rate does not exceed 1 although the replay winning probability as a whole becomes higher and the medal payout rate becomes higher than the normal gaming state. . On the other hand, in the second RT, the replay winning probability as a whole is higher than in the first RT, and the medal payout rate exceeds 1. However, the replay winning probability in the first RT is higher than that in the normal gaming state, the medal payout rate is higher than that in the normal gaming state, and the replay winning probability in the second RT is higher than that in the normal gaming state. If the medal payout rate is to be increased, the present invention can be applied to a case where the medal payout rate in the first RT is 1 or more and a medal payout rate in the second RT is 1 or less. it can.

  The first RT and the second RT may have the same replay winning probability of the replay A and the replay B, that is, the same medal payout rate. When determining the number of continuing games, the expected value of the number of continuing games to be determined may be larger than the number of remaining games of the first RT. In this case, the Replay B winning in the first RT has the meaning of extending the number of RT games, and the player can be given a sense of expectation for the Replay B winning in the first RT. In addition, if the winning probability of Replay B in the first RT is higher than that in the normal gaming state, the normal gaming state and the first RT have the same replay winning probability for both Replay A and Replay B, that is, paying out medals. The rate may be the same. In this case, the first RT does not become a gaming state that is more advantageous to the player than the normal gaming state in terms of the medal payout rate, but the normal amount is higher because the probability of winning Replay B with the transition to the second RT is higher. The gaming state is more advantageous for the player than the gaming state.

  In the present invention, the replay B winning probability in at least the first RT is higher than the replay B winning probability in the normal gaming state, and the replay winning probability that combines the replay A and the replay B in the second RT is the replay winning probability in the normal gaming state. As long as it is higher, the winning probabilities of Replay A and Replay B can be applied to slot machines that are set to any probabilities in the normal gaming state, the first RT, and the second RT.

  In the above embodiment, the same number of replay B determination values in the first RT is stored according to the set value. However, the replay A determination value number in the second RT is set to It was stored in common regardless of the value. However, the number of replay A determination values in the second RT may also be stored individually according to the set value. As the number of determination values for Replay A in the second RT, the same value may be stored for any number of set values, but different values may be stored. By thus storing the number of replay A determination values in the second RT individually according to the set value, a slot machine that realizes the second RT in which the medal payout rate differs for each set value is easily designed. It becomes possible.

  In the above embodiment, watermelons with a payout of 15 medals more than other small roles are subject to internal lottery only when the gaming state is in regular bonus, and in case of double winning with other small roles It was sure to be won. In addition, the small role that maximizes the number of medals paid out was one type of watermelon. However, even in a gaming state other than the regular bonus, a small combination with the maximum number of paid-out medals may be a lottery target. The small role that is subject to the lottery in a gaming state other than the regular bonus may or may not include a type of small role that maximizes the number of medals to be drawn in the regular bonus.

  Alternatively, the number of payout medals when winning a watermelon may be nine, the same as the number of payout medals when winning a bell. Alternatively, the number of payout medals when winning a watermelon may be nine, and the number of payout medals when winning a bell may be smaller than this. Here, if the bet number at which the game can be started in the regular bonus is also defined as 3, the ratio of the number of medals to be paid out with respect to the set bet number even in the regular bonus game state in which the player can obtain the most medals. Is suppressed to 300%. For this reason, the wave of increase / decrease of medals held by the player according to the change of the game state becomes gentle, and the effect of suppressing the shooting property can be obtained.

  In the above embodiment, in a game in which the game state is controlled to the regular bonus, the watermelon is always won, including the case where the player wins at the same time as the bell or cherry. However, if the number of games won as defined above is defined as the regular bonus ending condition, if the game state is controlled by the regular bonus, it is not possible to win a role other than watermelon alone. The watermelon may be lost without winning. In this case, the number of medals consumed for setting the number of bets in the regular bonus cannot always be minimized, but the number of payout medals can always be maximized for each regular bonus. Profit will not be reduced.

  In the above-described embodiment, the regular bonus for lottery is watermelon, watermelon + bell, watermelon + cherry, but watermelon, bell, bell + cherry may be used. In this case, in the regular bonus game state, although the watermelon with the maximum payout medal cannot always be won, the number of winning games that will be the condition for ending the regular bonus by winning the cherry with the minimum payout medal count is counted. There is nothing to do. For this reason, it is possible to prevent a disadvantage of the player that the number of medals to be paid out to the player ends with a minimum number.

  In the above embodiment, since the watermelon from which 15 medals are paid out is configured by the symbol combination “bell-watermelon-bell”, the stop button 12L, as long as the watermelon winning flag is set, Regardless of the operation timing of 12C, 12R, it was a winning combination. On the other hand, for example, the watermelon symbol combination may be “bell-bell-watermelon” and may be missed depending on the operation timing of the stop button 12R.

  Here, for example, consider a case where a watermelon + bell is won and a symbol combination “bell-bell” is tempered on the winning line for the left and middle reels 3L, 3R. Control details that "watermelon" is stopped on the winning line according to the operation timing of the stop button 12R, "watermelon" is stopped, and "watermelon" cannot be stopped, "bell" is stopped May be written in the stop control table. Thus, even if a player wins a watermelon on the condition that the stop buttons 12L, 12C, and 12R are appropriate, the regular bonus gives the player a chance to obtain the maximum profit. Will be able to.

  In the above-described embodiment, for example, when the watermelon + bell is won, the control content for preferentially winning a watermelon with a large number of payout medals is written in the stop control table. Of course, if there is a possibility that a small combination with a large number of payout medals may be awarded due to the relationship between the symbol arrangement on the reels 3L, 3C, and 3R and the combination of winning combinations, the control content written in the stop control table is not necessarily limited. It is not necessary to preferentially derive a small combination with a large number of payout medals, and it may be a control content to preferentially derive a small combination with a small number of payout medals.

  For example, the watermelon symbol combination is the same “bell-watermelon-bell” as in the above embodiment, the cherry symbol combination is “cherry-watermelon-bell”, and the two watermelons play more than 15 watermelons. The cherries of this shall be derived with priority. Here, for example, consider a case where a watermelon + cherry is selected and the “watermelon-bell” symbol combination is on the winning line for the middle and right reels 3C, 3R. Stop contents that “cherry” is stopped if the “cherry” can be stopped on the winning line by the operation timing of the stop button 12L, and “watermelon” is stopped if “cherry” cannot be stopped. May be written in the stop control table. Thus, even if a player wins a watermelon on the condition that the stop buttons 12L, 12C, and 12R are appropriate, the regular bonus gives the player a chance to obtain the maximum profit. Will be able to.

  In the above embodiment, the regular bonus, the big bonus (1) or the big bonus (2) and the cherry are simultaneously selected as the lottery objects. Including this, lottery of special roles such as regular bonus, big bonus (1) or big bonus (2) and lottery of non-special roles (small role, Replay A, Replay B) are performed in the same flow. I was trying. On the other hand, the lottery for special roles and the lottery for non-special roles may be performed separately.

  FIG. 20 is a diagram schematically showing a winning determination table applied in this modification. FIG. 21 is a flowchart showing in detail a lottery process applied in this modification. Other configurations and processes are the same as those of the slot machine 1 according to the above embodiment.

  As shown in FIG. 20, the winning determination table includes a small role winning determination table and a bonus winning determination table for each gaming state, which are stored in the ROM 113 in advance. Both the small role winning determination table and the bonus winning determination table are prepared according to the set values, and those corresponding to the set values are used in the lottery process, but the illustration is omitted here. doing. Note that JACIN in the small role game is a special role, but there is no carryover of the winning flag unlike the regular bonus, regular bonus in big game (RT), big bonus (1) or big bonus (2). A range of determination values is registered in the determination table.

  Here, as shown in FIG. 20A, in the normal game state, the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is not carried over from the previous game. Sometimes, an internal lottery is performed using both the small role table (1) corresponding to the normal gaming state and the bonus winning determination table. In FIG. 20 (a), the hatched range is a regular bonus, a big bonus (1) or a big bonus (2) and a cherry if the value of the random number for internal lottery is a value within this range. It is the range that will be won by overlapping.

  On the other hand, even in the normal gaming state, when the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is carried over from the previous game, FIG. As shown in (), only the small role table (1) corresponding to the normal gaming state is used, and the internal lottery is performed.

  Even when the gaming state is in the first RT or the second RT, the internal lottery is performed by the same method as in the normal gaming state. However, in the small role table used in the first RT, the small role in the normal gaming state is used. The range of determination values that are selected for Replay B are included in the range that is lost in the table and that overlaps the range that is lost in the bonus table. In the small role table used in the second RT, the range of determination values won for Replay A is the range that is lost in the normal gaming state small role table in the normal gaming state, and the bonus table is lost. It extends to the range that overlaps the range. The bonus table is commonly used in the normal gaming state, the first RT, and the second RT.

  When the game state is a small role game or a regular bonus (including the case where it is provided during the big bonus), the regular bonus, the big bonus (1) and the big bonus (2) are not drawn in the first place. As shown in FIGS. 20C and 20D, only the small role table (2) corresponding to the small role game or only the small role table (3) corresponding to the regular bonus is used. Is done.

  In the lottery process shown in FIG. 21, the process of steps S1101 to S1103 and the point of shifting to the RAM abnormality error process when it is determined in step S1102 that the set value is not in the range of 1 to 6 are described above. This is the same as the lottery process (steps S501 to S503 in FIG. 14). Further, the process of transmitting a win status notification command after the win flag setting status in the game is confirmed (step S1114) is the same as the process of step S520 of FIG.

  After acquiring a random number for internal lottery in step S1103, a small winning combination determination table prepared according to the current gaming state (usually, the first RT, the second RT, the small role game, or the regular bonus) and the set value is displayed. It is set as a winning determination table used for internal lottery (step S1104). Next, a determination value for winning each combination registered in the set small role winning determination table is sequentially compared with the internal lottery random value acquired in step S1103 (step S1105) and set. It is determined whether or not any combination registered in the small combination winning determination table is won (step S1106).

  When winning any of the winning combinations, the winning flag of the winning winning combination is set in the RAM 112. Here, when winning the bell + watermelon, the bell winning flag and the watermelon winning flag are set redundantly, and the cherry + If the watermelon is won, the cherry winning flag and the watermelon winning flag are set in duplicate (step S1107). Then, the process proceeds to step S1108. If no winning combination is won, the process proceeds to step S1108.

  In step S1108, whether or not the current gaming state is a regular bonus or a big bonus (small role game) is determined based on whether or not the regular bonus medium flag or the big bonus medium flag is set in the RAM 112. If the current gaming state is a regular bonus or a big bonus, the process directly proceeds to step S1114.

  If the current gaming state is neither a regular bonus nor a big bonus, it is either the normal gaming state, the first RT, or the second RT. In this case, the regular bonus winning flag, the big bonus (1) winning flag is stored in the RAM 112. Alternatively, it is determined whether or not the big bonus (2) winning flag has already been set in the game before the previous time and has been carried over without winning (step S1109). If the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is already set, the process proceeds to step S1114 as it is.

  If none of the regular bonus winning flag, the big bonus (1) winning flag and the big bonus (2) winning flag is set, the bonus winning determination table corresponding to the set value is used as the winning determination table used for the internal lottery. Setting is performed (step S1110). Next, the winning value of each combination registered in the set bonus winning determination table is sequentially compared with the internal lottery random value acquired in step S1103 (step S1111), and the set bonus is determined. It is determined whether or not any combination registered in the winning determination table is won (step S1112). If any winning combination is won, the winning flag of the winning combination is set in the RAM 112 (step S1113), and the process proceeds to step S1114. If no winning combination is won, the process proceeds to step S1114.

  In this way, a separate winning determination table is prepared for the special role and the non-special role, and the random number value for internal lottery is set to a value that is won for the special role in the normal gaming state, the first RT or the second RT. When responding to a value for winning a non-special role, both the special role and the non-special role will be won simultaneously. In this case, even if the display result of the variable display device 2 is a prize for a small role or a replay based on a winning flag for a non-special role such as a small role or a replay, the special role is still won. there is a possibility. Thereby, a player's expectation with respect to the winning of the special role can be enhanced, and the interest of the game can be improved.

  Even if a special role is not won as a result of the internal lottery, there is a possibility that a small role or replay (cherry in this variation) may be won, so the player's expectation is maintained. be able to. Furthermore, if the winning flag for the special role is not carried over from the previous game in the normal gaming state, the first RT or the second RT, the internal lottery is performed using both the small role winning determination table and the bonus winning determination table. However, if the special combination winning flag is carried over from the previous game, the internal lottery may be performed using only the small combination winning determination table. Thereby, the normal lottery state, the internal lottery in the first RT and the second RT can be performed by a simple process.

  In this modification, the random numbers for internal lottery used for the determination of winning of special roles and the random numbers for internal lottery used for determination of winning of non-special roles were the same, but different random numbers were used. Also good. Also, regardless of whether the regular bonus winning flag, big bonus (1) winning flag, or big bonus (2) winning flag is carried over, it is determined that the small role winning is determined in the normal gaming state, the first RT or the second RT. Lottery is performed using both the table for bonus and the table for determining bonus winning, and the regular bonus winning flag, big bonus (1) winning flag, or big bonus (2) winning flag is carried over from the previous game. Sometimes, when a regular bonus, a big bonus (1) or a big bonus (2) is won, the winning may be invalidated.

  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, 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 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. 22 is an explanatory diagram of a first modification of the processing (steps S503 and S1103) until the CPU 111 processes the random numbers extracted from the random number generation circuit 115 into random numbers 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. 23 is an explanatory diagram of a second modification of the processing (steps S503 and S1103) until the CPU 111 processes the random numbers extracted from the random number generation circuit 115 into random numbers 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.

  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 small role game, the normal gaming state, or RT, the game can be started only by setting 3 as the number of bets. On the other hand, even in a small role game, a normal game state or 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 make it.

  When the small bet game, the normal gaming state, and RT (the first RT and the second RT) are set with 1 or 2 as the bet number, the winning probability of the small role in the internal lottery is more than when the bet number is set as 3. The number of medals to be paid out when winning a small role can be increased. In addition, in a slot machine that can set any one, two, or three betting numbers in a small role game, a normal gaming state, and RT, the number of determination values is stored in common for all of the setting values 1 to 6. In addition to having a combination, it is also possible to have a combination 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, it is determined whether or not the set value is in the range of 1 to 6 in the internal lottery process executed for each game, and it is determined that the set value is not in the range of 1 to 6 In this case, the processing is shifted to the RAM abnormality error processing. In the internal lottery process, not only determines whether the set value is appropriate, but also determines whether the bet number is appropriate (whether the bet number is determined according to the gaming state). Even when it is determined that the number of bets is not appropriate, the processing may be shifted to the RAM abnormality error processing.

  In the above embodiment, when the gaming state is in the big bonus, the game state is first controlled to the small role game, and further the JACIN winning is based on the JACIN winning in the small role game, so that the gaming state is a regular in the big bonus. The bonus was to be controlled. However, the condition for controlling the gaming state in the big bonus) to the regular bonus is not limited to this. For example, when a big bonus (1) or big bonus (2) is won, first, a big bonus medium flag is set in the RAM 112. In a game in which the big bonus medium flag is set, a regular bonus is stored in the RAM 112 when the start lever 11 is operated. It may be determined whether the medium flag is set, and if the regular bonus medium flag is not set, this may be set to control the regular bonus. In this case, even when controlling to the regular bonus for the first time after winning the big bonus (1) or the big bonus (2), the regular bonus is finished once and the regular bonus is not finished yet. The same process may be performed when controlling to a bonus.

  When the big bonus (1) or 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 the 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.

  If the big bonus is controlled by these methods, the big bonus can be provided by repeating the regular bonus until the number of payout medals reaches a specified number. In this case, even with a big bonus that ends when the number of paid-out medals exceeds the specified number, the number of medals used for setting the number of bets can be minimized by winning a watermelon where 15 medals are paid out in all games. The maximum net increase in medals required for calculation can be obtained.

  It should be noted that the regular bonus end condition is not that the number of winning games or the number of digested games has reached a predetermined number of games, but also that the number of payout medals has reached a predetermined number, By winning a watermelon from which medals are paid out, the number of medals used for setting the number of bets can be minimized, and the net increase in the maximum required medal can be obtained. It is not a big bonus provided by repeating a regular bonus, but a regular bonus provided based on a regular bonus prize or a JACIN prize.

  In the above embodiment, the gaming state of the slot machine 1 includes RT (first RT and second RT), regular bonus, and big bonus (small role game and regular bonus) in addition to the normal gaming state. It was. On the other hand, the maximum stop delay time of any one or more of reels 3L, 3C, 3R is shortened (for example, 75 milliseconds (one frame slip)) and a prize is awarded to a small role regardless of the result of the internal lottery. Additional gaming status such as CT (Challenge Time), AT (Assist Time) that informs the game procedure (especially the type of the small role that has been won) for winning the role with the winning flag set It may be included. In addition to the first RT and the second RT described above, the RT includes an RT (hereinafter referred to as a third RT) controlled based on the derivation of an RT symbol that does not serve as another role such as the replay B. It may be a thing. Even if the transition to CT, AT, and 3rd RT is performed based on winning a corresponding combination, the additional combination is a special combination, and the internal lottery includes the above embodiment and FIG. A method similar to the internal lottery of the regular bonus, the big bonus (1), and the big bonus (2) in the modification shown in FIG. 21 can be applied.

  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.
