Abstract

<P>PROBLEM TO BE SOLVED: To increase excitement and enjoyment of a game by making the timing of being controlled to a specific play state less noticeable to a player, where a replay game display result is more likely to be delivered than in a normal play state. <P>SOLUTION: With a symbol of "Cherry" coming at a left reel on a prize winning line, there are seven kinds of symbols, Cherries A to G, to be defined as winning combinations. When any of these winning symbols are obtained, two tokens are paid out for each prize winning line. When Cherry A is obtained, the game goes into an RT (Replay Time)-controlled state in addition to the token payout. However, when one of Cherries B to G is obtained, the game is not controlled by RT. Regarding internal lotteries, there are two cases where the seven kinds of Cherries A to G are simultaneously won and where the six kinds of Cherries B to G are simultaneously won. When the Cherries A to G are won, Cherry A is delivered preferentially to Cherries B to G. <P>COPYRIGHT: (C)2013,JPO&amp;INPIT

Description

  The present invention relates to a slot machine, and more particularly to control of a specific gaming state in which the probability that it is determined that the derivation of a replay display result is permitted is higher than that in the normal gaming state.

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

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

  By using the fact that the player can obtain the benefit of not having to spend medals for setting the number of bets due to this replay winning, the normal gaming state is the probability of winning a role other than replay by a predetermined number of games. There is a slot machine that defines RT (Replay Time) that increases the replay winning probability without changing the game as a special game state other than a special game state called a bonus such as a big bonus or a regular bonus. By making the gameability including the control to RT, it is possible to make the player expect a transition of the game state in addition to the bonus, and to improve the interest of the game.

  Here, there is a slot machine in which a gaming state is shifted to RT by deriving a predetermined RT symbol as a display result of the variable display device in a normal gaming state (for example, Patent Document 1, 2). In addition, there are a slot machine that transitions the gaming state to RT when the big bonus or the regular bonus ends, and a slot machine that transitions the gaming state to RT when the RT transition lottery is won.

JP 2005-131323 (paragraphs 0035 and 0086) Japanese Patent Laying-Open No. 2005-199049 (paragraph 0072)

  However, if the derivation of the RT symbol that triggers the transition to RT as in the slot machines of Patent Documents 1 and 2 can be easily identified, the trigger is too obvious and the game becomes monotonous. There was a problem. If the RT is to be controlled after the end of the big bonus or regular bonus, the RT transition is too obvious and the game becomes monotonous, and there is no technical intervention for the control to the RT was there. When RT is controlled by winning the RT transfer lottery, there is a problem that technical intervention does not work for the control to RT, and the processing load increases by the amount of RT transfer lottery. was there.

  The present invention improves the interest of the game by making it difficult for the player to understand the opportunity to be controlled to a specific game state that increases the probability that the replay display result is allowed to be derived from the normal game state. An object of the present invention is to provide a slot machine that can be made to operate.

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 plurality of variable display sections (each of which displays a plurality of types of identification information in a variable manner). The display result is derived to the variable display device (variable display device 2) including the reels 3L, 3C, and 3R, thereby completing one game, and the display result derived on the winning line set in the variable display device. In slot machines that can win according to
Prior to the display result being derived on any of the plurality of variable display units for each game, a plurality of types of small combination display results accompanied by the addition of the gaming value as a winning display result that can be derived on the winning line (Watermelon, bell, watermelon bell, cherry A to cherry G) and a plurality of kinds of replay display results (replays) that allow the next game to be played without using the gaming value for setting the bet number A pre-determining means (step S403, FIG. 14, FIG. 22) for determining whether or not to allow the derivation of the winning display result;
Derivation operation means (stop buttons 12L, 12C, 12R) operated when deriving display results from the plurality of variable display units,
Derivation control means for causing each of the plurality of variable display sections to derive a display result according to a procedure in which the derivation operation means is operated and a determination result of the prior determination means when each of the derivation operation means is operated. (Step S404)
The pre-determining means includes
Identification of a specific type of identification information in which a display result derived from the first variable display unit (reel 3L) among the plurality of variable display units on the winning line is variably displayed on the first variable display unit. Information (cherry), and the display result derived on the second variable display section (reel 3R) different from the first variable display section on the winning line is displayed in a variable manner on the second variable display section. A single allowance determining means for determining only that the derivation of the first specified small combination display result (cherry A), which is the small combination display result serving as the first type of identification information (cherry), is permitted (FIG. 5B). (C): Cherry B to Cherry G),
It is determined that the derivation of the first specific small combination display result is allowed, and the display result derived to the first variable display unit in the winning line becomes the specific type of identification information, The second type of identification information (BAR, 7, JAC) that is different from the first type of identification information among the identification information that is variably displayed on the second variable display unit. , Replay, watermelon, bell) simultaneous permissible determining means for determining that the second specific small combination display result (Cherry B to Cherry G) is permitted to be derived (FIG. 5B, ( c): Cherry A to Cherry G)
In the second variable display unit, the derivation control unit determines that the derivation of the first specific small combination display result and the second specific small combination display result is permitted by the simultaneous allowance determination unit. At the time of simultaneous permission determination for deriving the second identification information when the deriving operation means is operated in a procedure that can derive both the first type identification information and the second type identification information on the winning line. Including derivation control means,
The slot machine is
When the display result derived on the winning line becomes the second specific small combination display result, the probability that the pre-determining means determines to permit the derivation of the re-game display result is set to the normal gaming state. It further comprises specific game state control means (step S816) for controlling the game state to a higher specific game state (RT).

  In the slot machine, when the first specific small combination display result is derived on the pay line set in the variable display device, the gaming state is controlled to the specific gaming state. In the first specific small role display result, the display result derived to the first variable display unit in the winning line is the specific type of identification information, and the display result derived to the second variable display unit on the winning line is the first 2 is a small combination display result that is the first type of identification information among the identification information that is variably displayed on the variable display section. Here, the display result derived to the second variable display unit on the winning line is further included in the small combination display result in which the display result derived to the first variable display unit on the winning line is the specific type of identification information. There is also a second specific small combination display result that becomes the second type of identification information among the identification information that is variably displayed on the second variable display section. Both the first specific small combination display result and the second specific small combination display result are common in that they are derived as a display result of the variable display device and are small combination display results to which game value is given.

  By the way, in the conventional slot machine, it is awarded that a predetermined type of identification information (corresponding to the specific type of identification information in the slot machine) is derived to one of the plurality of variable display units. As a part of the display result, there are many that are particularly defined as a part of the small role display result. For a player who is accustomed to the game in such a conventional slot machine, the first variable display is performed both when the first specific small combination display result is derived and when the second specific small combination display result is derived. Derivation of specific types of identification information to the department gives an impression that the small role display result has been derived, and it is difficult to distinguish between the first specific small role display result and the second specific small role display result. .

  In other words, it is difficult to understand that the first specific small role display result has been derived as the display result of the variable display device, and as a result, it becomes difficult for the player to control the specific gaming state, thereby improving the interest of the game. Can be made. In addition, since the first specific small combination display result and the second specific small combination display result can give an impression that the winning display result is generated by the specific type of identification information derived to the first variable display section, In fact, even if the derivation of the first specific small role display result is triggered by the control to the specific game state, the specific game state transition lottery is performed by the derivation of the specific type of identification information to the first variable display unit, It is possible to give a player a sense that the game is controlled to a specific game state, and to further improve the interest of the game.

  In addition, in the determination by the pre-determining means, when it is simultaneously determined that the derivation of the first specific small combination display result and the second specific small combination display result are permitted, and the second specific small combination In some cases, it is determined only that the derivation of the display result is permitted. In the case of simultaneous determination, when the derivation operation means is operated in a procedure in which both the first type identification information and the second type identification information can be derived on the winning line in the second variable display unit, the second identification Information is derived. For this reason, since the first specific small combination display result cannot be derived even if determined simultaneously, the player's sense of expectation for the specific game state is not diminished, and the interest of the game can be improved.

  In addition, the derivation of the first specific small role display result is used as a trigger for the transition to the specific gaming state, but it is determined that the first specific small role display result is allowed to be derived simultaneously with the second specific small role display result. In addition, even if it is determined that the derivation is permitted, the winning display result may be missed depending on the operation procedure of the derivation operation means. In this case, the technical intervention is maintained with respect to the transition to the specific game state, so that the interest of the game can be further improved. Since there is no need to make a lottery for shifting to a specific gaming state, the processing load can be reduced.

  The number of game values given when the first specific small combination display result is derived and the number of game values given when the second specific small combination display result is derived , They can be the same or different. However, in order to make it difficult for a player to notice the derivation of the first specific small role display result, the number of gaming values given when the first specific small role display result is derived and the second specific small role It is preferable that the difference from the number of game values given when the display result is derived is smaller, and it is most preferable that the number is the same.

  Also, for example, when the variable display device is composed of three variable display units, left, middle, and right, any one variable display unit is the first variable display unit, and the other is the second variable display. Can be applied as a part. In this case, the remaining one variable display portion is neither the first variable display portion nor the second variable display portion, but the first specific small combination display result and the second specific small combination display result are both on the winning line. No matter what kind of identification information the display result derived to the remaining one variable display section is. Here, since the types of display modes of the first specific small combination display result and the second specific small combination display result are increased, the derivation of the first specific small combination display result can be made more difficult for the player to understand.

  However, the first specific small combination display result and the second specific small combination display result are the display results derived from the remaining one variable display unit other than the first variable display unit and the second variable display unit of a predetermined type. It may be conditional on being identification information. For example, a display result in which a specific type of identification information is derived in the first variable display unit, a predetermined type of identification information is derived in the third variable display unit, and the first type of identification information is derived in the second variable display unit on the winning line. On the winning line, a specific type of identification information is displayed on the first variable display unit, a predetermined type of identification information is displayed on the third variable display unit, and a second type of identification information is displayed on the second variable display unit. The display result from which the identification information is derived can be used as the second specific small combination display result. The predetermined type of identification information may be the same type of identification information as the specific type of identification information or a different type of identification information.

  In addition, on the winning line, identification information of a specific type is derived in the first variable display unit, identification information of the first type is derived in the second variable display unit, and identification information other than a predetermined type is derived in the third variable display unit. The display result is the first specific small combination display result, and on the winning line, the specific information of the specific type is displayed on the first variable display unit, the second type of identification information is displayed on the second variable display unit, and the third variable display unit is predetermined The display result from which the type of identification information is derived can be used as the second specific small combination display result. The predetermined type of identification information may be the same type of identification information as the second type of identification information or a different type of identification information.

In the slot machine, the derivation control means is provided on the condition that the derivation operation means is operated in a predetermined procedure when it is determined that the derivation of the second specific display result is permitted. In the two-variable display unit, the second type of identification information may be derived on the winning line. In this case,
The simultaneous permissible derivation control means determines whether the first type of identification information can be derived on the winning line in the second variable display section when the derivation operation means is operated in the predetermined procedure. Regardless of the above, the second type identification information is derived, and when the derivation operation means is operated in a procedure other than the predetermined procedure, the first type identification information is displayed in the second variable display section. It can be derived on the winning line.

  In this case, when the simultaneous determination is made, the derivation of the first specific small combination display result is prioritized, but the second specific small combination display result may be derived depending on the operation procedure of the derivation operation means. . For this reason, even if the player can recognize the derivation of the second specific small role display result, it may be caused by the loss of the first specific small role display result, or the second specific small role display result may be derived in the first place. It is not known whether only the permissible decision has been made, and the entertainment of the game can be improved.

The slot machine is
An effect display that is provided separately from the variable display device, is provided more easily than the variable display device, and variably displays a plurality of types of effect identification information that can be individually identified by a plurality of effect variable display units. A variable display device (virtual reel of the liquid crystal display 4);
It is possible to further include effect variation display control means (steps S1013 and S1015) for causing the effect variable display device to derive an effect display result corresponding to the display result derived on the winning line. In this case,
The production-use variation display control means is operable when the display result derived on the winning line is the first specific small combination display result or the second specific small combination display result. An effect specific small role deriving means (step S1015) for deriving an effect specific small role display result (cherry) determined in common for both the first specific small role display result and the second specific small role display result. Can be included.

  Thus, when the first specific small combination display result is derived on the winning line set in the variable display device and when the second specific small combination display result is derived, the common specific display result for production is used for the production. By causing the variable display device to derive, it is possible to make it difficult for the player to notice that the first specific small role display result has been derived to the variable display device, and to detect that the player has been controlled to the specific gaming state. Can be prevented. In addition, since the production variable display device is provided so as to be more visible than the variable display device, the first specific small role display result is less likely to be noticed, so that the first is derived to the variable display device. Even if the specific small combination display result is in a relatively easy-to-understand manner, it is possible to make it difficult for the player to notice the first specific small combination display result.

In the above slot machine,
The plurality of variable display sections rotate display bands (reels 3L, 3C, and 3R) each having a plurality of types of identification information that can be identified by driving a stepping motor (reel motors 3ML, 3MC, and 3MR). Thus, the identification information may be variably displayed, and the display result may be derived by stopping the driving of the stepping motor. In this case, the slot machine is
A determination result information setting unit (RAM 112) that sets determination result information (winning flag) according to the determination result of the prior determination unit 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. 10: stop control table) that uniquely specify the display result derived for the number of steps of the stepping motor. Control pattern selection means (step S705) 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 S715). In this case,
The control pattern selection means includes a first specific small combination determination result information and a second specific small combination display indicating that the determination result information setting means has determined that the first specific small combination display display result is allowed to be derived. When the second specific small role determination result information indicating that the derivation of the result is determined is set, the number of steps at the operation time point of the derivation operation means corresponding to the second variable display unit is the second When the number of steps is such that the second type of identification information can be derived to the variable display section, the second type of identification information can be converted into the first type of information even if the number of steps of the first type of identification information can also be derived. 2 It includes a specific small combination control pattern control means for selecting a control pattern to be derived by the variable display section.

  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. 10: stop control table) that uniquely specify the display result derived with respect to the number of steps of the stepping motor 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 S705)
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 S715). In this case,
The control pattern selection means includes a first specific small combination determination result information and a second specific small combination display indicating that the determination result information setting means has determined that the first specific small combination display display result is allowed to be derived. When the second specific small role determination result information indicating that the derivation of the result is determined is set, the number of steps at the operation time point of the derivation operation means corresponding to the second variable display unit is the second When the number of steps is such that the second type of identification information can be derived to the variable display section, the second type of identification information can be converted into the first type of information even if the number of steps of the first type of identification information can also be derived. 2 It includes a specific small combination control pattern control means for selecting a control pattern to be derived by the variable display section.

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. 10: stop control table) that uniquely specify the display result derived with respect to the number of steps of the stepping motor when the derivation operation means corresponding to the unit is operated Control pattern selection means (step S705) for uniquely identifying 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 S715). In this case,
The control pattern selection means includes a first specific small combination determination result information and a second specific small combination display indicating that the determination result information setting means has determined that the first specific small combination display display result is allowed to be derived. When the second specific small role determination result information indicating that the derivation of the result is determined is set, the number of steps at the operation time point of the derivation operation means corresponding to the second variable display unit is the second When the number of steps is such that the second type of identification information can be derived to the variable display section, the second type of identification information can be converted into the first type of information even if the number of steps of the first type of identification information can also be derived. 2 It includes a specific small combination control pattern control means for selecting a control pattern to be derived by the variable display section.

  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 with respect to the number of steps of the stepping motor. 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.

  It is determined that the first specific small combination determination result information set when it is determined to permit the derivation of the first specific small combination display result and the second specific small combination display result is permitted to be derived. The second specific small combination determination result information that is set at the time is set in the determination result information setting means as separate determination result information. For example, when designing a new slot machine that uses the above-mentioned slot machine specifications to determine the first specific small combination display result as the winning display result and not the second specific small combination display result as the winning display result. Compared to the case where one type of determination result information is set when it is simultaneously determined that the derivation of the first specific small combination display result and the second specific small combination display result is permitted, Development can be done.

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. 5, FIG. 6) may be further provided. here,
The range specifying data storage means is in a special gaming state that is more advantageous for the player than the normal gaming state other than the specific gaming state by the pre-determining means when it is determined that the determination numerical data is included. A determination value determined to permit the derivation of both a special display result that is a winning display result accompanied by a transition and a non-special display result that is a winning display result other than the special display result including the small role display result A plurality of range specifying data including a plurality of range specifying data including overlapping range specifying data (regular bonus + watermelon, big bonus (1) + watermelon, big bonus (2) + watermelon) It may be. 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 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 determination value for determining that the pre-determining means allows the derivation of a special display result that is a winning display result accompanied by a transition to a special gaming state that is more advantageous to the player than a normal gaming state other than the specific gaming state. Special range specifying data storage means (FIG. 21: bonus table) for storing special range specifying data determined so that the range can be specified;
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. 21: small role table) for storing non-special range specifying data included in the range;
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;
Indicates that the permission for deriving the special display result set in the determination result information setting unit is determined until the special display result is derived based on the determination to permit the derivation of the special display result. Special decision carryover means (special role temporary storage work) for carrying over the special decision result information may be further provided. here,
The pre-determining means includes
On the condition that the special decision result information is not carried over by the special decision carry-over means (step S1109 (NO)), the numerical value data for determination is obtained from the special range specification data stored in the special range specification data storage means. Special decision means (steps S1110 to S1113) 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 specified decision value;
Regardless of whether or not the special decision result information is carried over by the special decision carry-over means (there is no judgment step as in step S1109), the judgment numerical data is stored in the non-special range specifying data storage means. The non-special display result is determined by determining whether the non-special numerical data for determination is included in the range of the determination value specified by the non-special range specifying data stored in the non-special range specifying data storage means Non-special determination means (steps S1104 to S1107) for determining whether or not to permit derivation of.

  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. 12) that cancels the disabled state and enables 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 The first storage area (regular bonus + watermelon, big bonus (1) + watermelon, big bonus (2) + watermelon, JACIN, watermelon, watermelon bell + watermelon, bell, watermelon bell + bell, watermelon bell) , Replay (normal), replay (RT)) and second range specifying data different from the first range specifying data among the plurality of range specifying data for each type of the permissible stage. Storage area (Regular Bonus, Big Bonus (1), Big Bonus (2), Cherry A to Cherry G, Cherry B to Cherry G) Range specifying data storage means (5, 6) comprising a can be made further comprising a.

  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 area (big bonus (1), big bonus (2), cherry A to cherry G, cherry B to cherry G) for individually storing range specifying data that can specify different ranges of judgment 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.

In this case, the slot machine also

Numerical data input means (FIG. 23) 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
First numerical value updating means (refresh register 111R) for updating the second numerical data at a predetermined timing;
Second numerical value updating means (refresh register 111R) for updating third numerical data different from the second numerical data at a predetermined timing;

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.

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.

One word of data handled by the CPU 111 is 8 bits (1 byte), and the addresses of the RAM 112 and the ROM 113 are also assigned in units of 8 bits.

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

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

The random number generation circuit 115 is provided for each type of random number used for the progress of the game, and a range of numerical values to be counted for each type of random number is determined. The CPU 111 sends an instruction to the sampling circuit 116 according to the processing to acquire the numerical value indicated by the random number generation circuit 115 as a random number (hereinafter, this function is referred to as a hardware random number function). A random number extracted by the hardware random number function is used as a random number for internal lottery described later.

  The CPU 111 also has a function of updating the numerical value of the specific address in the RAM 112 by timer interrupt processing and acquiring the updated numerical value as a random number (hereinafter, this function is referred to as a software random number function). The CPU 111 transmits various commands to the effect control board 102 via the I / O port 114. Each of these commands consists of 8 bits. Note that information (commands) is sent from the game control board 101 to the effect control board 102 only in one direction, and no information (commands) is sent from the effect control board 102 to the game control board 101.

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

  The game control board 101 also includes a flow path switching solenoid 49, a payout display 51, a credit display 52, a loading instruction lamp 59, a start lamp 60, a replay lamp 62, a HIT lamp 54, BET button lamps 70a and 70b, an operation. Valid lamps 63L, 63C, 63R and winning display lamps 45a to 45d are connected, and the CPU 111 controls these operations according to the progress of the game.

  The game control board 101 is connected to reel motors 3ML, 3MC, and 3MR via a reel relay board 103. The CPU 111 refers to the winning flag set in the RAM 112 and controls the reel motors 3ML, 3MC, and 3MR via the reel relay board 103 to stop the reels 3L, 3C, and 3R. An effect control board 102 is further connected to the game control board 101 via an effect relay board 106.

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

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

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

  The effect control board 102 is connected with game effect lamps 75A to 75E, a liquid crystal display 4, speakers 7L and 7R, a fluorescent lamp 6, 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, a regular bonus medium signal, a medal IN signal, and the like input from the game control board 101 via the reel relay board 103. The medal OUT signal is output to the external device. In addition, a winning status signal, a reel control signal, and a stop switch signal may be output to an 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 A winning flag storage work and a winning flag storage work, which will be described later, are provided in the general work 112-2, and a special role temporary storage work and a general role temporary storage work are provided in the important work 112-1. The general work 112-2 is cleared for each game, but the important work 112-1 is not cleared for each game. 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. Hereinafter, a setting value changing operation using 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 the combination of “BAR-BAR-BAR” is aligned on any of the winning lines (five) in the normal gaming state or RT. When the regular bonus is won, the gaming state shifts from the normal gaming state to the regular bonus. The regular bonus ends when 12 games are consumed, or when 8 games are won (any kind of combination is possible), whichever comes first. While the 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.

  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. However, when the regular bonus, the big bonus (1) or the big bonus (2) is won (including the case of carrying over), if the other bonuses are also won, the stop buttons 12L and 12C When the regular bonus, the big bonus (1), or the big bonus (2) can be derived by the operation timing of 12R, this is preferentially derived over the other winning combinations.

  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.

  A watermelon is awarded when any combination of “watermelon-watermelon-watermelon” is aligned on any winning line (5 or 1) in any gaming state, and 12 medals are paid out. “Watermelon” for the inner reel 3C is always arranged at intervals of 5 frames or less, but “watermelon” is not necessarily arranged at intervals of 5 frames or less for the left and right reels 3L, 3R. Even if the watermelon is won in the internal lottery to be described later, the watermelon cannot be won if the operation timing of the stop buttons 12L, 12C, and 12R is not an appropriate timing. In this embodiment, when the watermelon is won in the regular bonus, the number of medals to be paid out is larger and the watermelon bell that is not missed is always won, so the watermelon is not won with the regular bonus.

  A bell is awarded when a combination of “bell-bell-bell” is arranged on any winning line (5 or 1) in any gaming state, and eight medals are paid out. Since all of the reels 3L, 3C, and 3R are arranged at intervals of 5 frames or less, when a bell is won in the internal lottery described later, the bell is always won (however, regular Bonus, Big Bonus (1) or Big Bonus (2) derivation is prioritized). In this embodiment, when a bell is won in the regular bonus, the number of medals to be paid out is larger and a watermelon bell that is not missed is always won. Therefore, the regular bonus is not won.

  The watermelon bell is awarded when the combination of “bell-watermelon-bell” is aligned on the winning line (1) in the regular bonus, and 15 medals are paid out. The “bell” on the left and right reels 3L and 3R and the “watermelon” on the inner reel 3C are always arranged within 5 frames, so that the watermelon bell is selected in the internal lottery described later. For example, the watermelon can be awarded regardless of the operation timing of the stop buttons 12L, 12C, and 12R (except when the derivation of the regular bonus, the big bonus (1), or the big bonus (2) is prioritized). ). The watermelon bell is derived in preference to the watermelon, bell or cherry A to cherry G because the number of medals is large even when the watermelon, bell or cherry A to cherry G are selected. .

  Cherry A has a “Cherry” symbol on the left reel 3L and a “Cherry” symbol on the right reel 3R in any of the pay lines (5) in a gaming state other than the regular bonus. When a prize is awarded. Cherry B has a “Cherry” symbol on the left reel 3L and a “BAR” symbol on the right reel 3R in any of the pay lines (5) in a gaming state other than the regular bonus. Win a prize. Similarly, in Cherry C, Cherry D, Cherry E, Cherry F, and Cherry G, the symbols for the right reel 3R are “7”, “JAC”, “Replay”, “Watermelon”, and “Bell”, respectively. . Any of the cherry A to the cherry G may be of any symbol derived to the inner reel 3C, but “ANY” represents that the symbol does not matter.

  If Cherry A to Cherry G are also won in the internal lottery, if the “Cherry” symbol is stopped at the top or bottom of the left reel 3L (other than the regular bonus, it will not stop at the middle) Since “Cherry” is arranged within 7 frames for the right reel 3R, “Cherry” stops at either the upper or lower stage and wins Cherry A. Cherry B to Cherry G will not be won without winning Cherry A. Here, when "Cherry" stops at the upper or lower stage of the right reel 3R, "JAC", "Replay", or "Bell" stops at the lower or upper stage, so when winning the Cherry A, At the same time, one of Cherry D, Cherry E or Cherry G is won.

  When winning from Cherry B to Cherry G in the internal lottery, even if the “Cherry” symbol is stopped at the upper or lower part of the left reel 3L (it will not stop at the middle part except for the regular bonus) The “cherry” does not stop on either the upper or lower stage of the reel 3R. In this case, two of the cherry B to cherry G will be won simultaneously according to the symbols stopped at the upper and lower stages of the right reel 3R.

  However, since the symbol “cherry” is not necessarily arranged within 7 frames for the left reel 3L, depending on the operation timing of the stop buttons 12L, 12C, 12R, cherry A to cherry G or cherry B to cherry Even if you win G, you may miss it. In the regular bonus, when Cherry A to Cherry G are won, the medal payout amount is larger and the watermelon that is not missed is always won. Therefore, the regular bonus will not win the Cherry A to Cherry G.

  When any of Cherry A to Cherry G is won, two medals are paid out per winning line. In game states other than the regular bonus, “Cherry” stops at the top or bottom of the left reel 3L, and two medals are awarded to two of Cherry A to Cherry G. To be paid out. When winning the Cherry A in the normal gaming state, the gaming state is set to RT only for 100 games from the next game (limited to the regular bonus, big bonus (1) or big bonus (2)). Controlled. Even if the cherry B to the cherry G are won, the gaming state is not controlled to RT. As will be described later, when the cherries B to G are won together with the cherry A, the cherry A with the control to the RT is preferentially derived even if the payout number of medals is the same.

  Replay is awarded when a combination of “replay-replay-replay” is arranged in any of the winning lines (5) in the normal gaming state or RT. With regular bonuses and big bonuses (small role game and regular bonus), even if this combination is available, replay prizes will not be awarded. Since “replay” is arranged at intervals of 5 frames or less for each of the reels 3L, 3C, and 3R, each of the reels 3L, 3C, and 3R always wins a replay when winning a replay in an internal lottery described later.

  When a replay is won, the medal will not be paid out, but the next game can be started without setting the bet number again, so the number of bets that became unnecessary in the next game (the regular bonus will not be replayed and will always be 3) This is substantially the same as when three corresponding medals are paid out.

  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, and a plurality of winnings are not won simultaneously in one game.

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

  When the gaming state is a regular bonus (including a case where the bonus is provided during a big bonus), watermelon bell + watermelon, watermelon bell + bell, watermelon bell, watermelon bell + cherry A to cherry G are sequentially read out as a target combination of internal lottery. When the game state is a small bonus game with a big bonus, regular bonus + watermelon, big bonus (1) + watermelon, big bonus (2) + watermelon, JACIN, watermelon, bell, cherry A ~ cherry G, cherry B ~ Cherry G is sequentially read out as a target combination for internal lottery.

  During normal gaming, regular bonus + watermelon, regular bonus, big bonus (1) + watermelon, big bonus (1), big bonus (2) + watermelon, big bonus (2), watermelon, bell, cherry A ~ Cherry G, Cherry B ~ Cherry G, and Replay (normal) are read out in order as the target combination of the internal lottery. When the game state is RT, regular bonus + watermelon, regular bonus, big bonus (1) + watermelon, big bonus (1), big bonus (2) + watermelon, big bonus (2), bell, cherry A to cherry G, Cherry B to Cherry G, and Replay (RT) are sequentially read out as the target combination of the internal lottery. The replay (normal) and the replay (RT) have different winning probabilities because the storage areas for the number of determination values described later are different, but the other points are common.

  In the internal lottery, the number of determination values determined for the internal lottery target combination is sequentially added to the internal lottery random number, and when the addition result overflows, it is determined that the winning combination is won. If the winning combination is determined, the winning flag of the combination is set in the RAM 112. The number of determination values is read in accordance with the storage address of the number of determination values registered in the role table stored in advance in the ROM 113. FIG. 5C is a diagram illustrating an example of the role-specific table. The number of determination values may be 256 or more, and cannot be stored for one word. Therefore, each determination value is registered using a storage area for two words. The number of determination values corresponding to the number of bets of each lottery object combination is common regardless of the set value, and is different depending on the set value. If the number of determination values is common regardless of the set value, a common flag is set (value is set to “1”).

  Regular Bonus + Watermelon, Big Bonus (1) + Watermelon, Big Bonus (2) + Watermelon are the roles subject to internal lottery in any gaming state other than the regular bonus. 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 or 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.

  Watermelon, bell, cherry A to cherry G, and cherry B to cherry G are roles that are subject to internal lottery in any gaming state other than the regular bonus. For the watermelon and the bell, the common flag is 1, and the storage address of the common determination value number is registered regardless of the set value. For the cherry A to cherry G and the cherry B to cherry G, the common flag is 0, and the storage address of the determination value number is registered individually according to the set value corresponding to each bet number.

  Replay (normal) is a role that is subject to internal lottery in a normal gaming state. 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 (RT) is a role that is subject to internal lottery only at 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. Watermelon bell + watermelon, watermelon bell + bell, watermelon bell, watermelon bell + cherry A to cherry G are roles that are subject to internal lottery with regular bonus. The common flag for these roles is also 1, and a common storage address is registered regardless of the set value.

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

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

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

  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 target combination of the internal lottery is a watermelon and the set value is 1 to 6. The address ADD + 46 is an address that is referred to when the subject combination of the internal lottery is watermelon bell + watermelon and the set value is 1-6. The address ADD + 48 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 + 50 is an address that is referred to when the subject combination of the internal lottery is watermelon bell + bell and the set value is 1-6. The address ADD + 52 is an address that is referred to when an internal lottery target role is a watermelon bell and a set value is 1 to 6. The address ADD + 78 is an address that is referred to when the subject combination of the internal lottery is watermelon bell + cherry A to cherry G and the set value is 1 to 6.

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

  Addresses ADD + 54, ADD + 56, ADD + 58, ADD + 60, ADD + 62, and ADD + 64 are addresses that are referred to when the target combination of the internal lottery is Cherry A to Cherry G and the set value is 1 to 6. The addresses ADD + 66, ADD + 68, ADD + 70, ADD + 72, ADD + 74, and ADD + 76 are addresses that are referred to when the target combination of the internal lottery is Cherry B to Cherry G and the set value is 1 to 6. Since each of Cherry A to Cherry G and Cherry B to Cherry G has different numbers of determination values stored according to the set values, the winning probabilities differ according to the set values.

  The address ADD + 80 is an address that is referred to when the target combination of the internal lottery is replay (normal) and the set value is 1-6. The address ADD + 82 is an address that is referred to when the target part of the internal lottery is replay (RT) and the set value is 1-6. Since a value larger than address ADD + 80 is registered in address ADD + 82, the replay winning probability in RT is higher than the replay winning probability in the normal gaming state.

  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.

  FIG. 8 is a diagram for explaining an area for storing the results of the internal lottery and an area for managing winnings. That is, in the RAM 112, the winning flag storage work (3 bytes) shown in FIG. 8A, the special role temporary storage work (1 byte) shown in FIG. 8B, and the general role shown in FIG. A temporary storage work (1 byte), an index search work (1 byte) shown in FIG. 8D, and a winning flag storage work (3 bytes) shown in FIG. 8E are provided.

  Here, since the winning flag storing work and the winning flag storing work are provided in the general work 112-2, they are always cleared at the end of one game, but the special role temporary storing work is designated as the important work 112-1. Since it is provided, it is not cleared for each game. In addition, the bits that are “unused” in the winning flag storing work and the winning flag storing work are bits that do not correspond to any combination, and the value thereof is always 0 (however, because of the inversion of the illegal winning prize) Except when the data of the winning flag storage work is reversed.)

  The winning flag of the lottery subject determined to be won in the internal lottery is first set in the winning flag storing work. Here, the fact that the winning flag is set means that the corresponding bit changes from 0 to 1. For example, when the regular bonus is won, the regular bonus winning flag in the most significant bit of the upper byte of the winning flag storing work is set. When the regular bonus + watermelon is won, the regular bonus winning flag and the watermelon winning flag are set in the winning flag storing work. When winning from Cherry A to Cherry G, seven of the Cherry A winning flag, Cherry B winning flag, Cherry C winning flag, Cherry D winning flag, Cherry E winning flag, Cherry F winning flag and Cherry G winning flag are set. .

  When the winning flag for special roles (regular bonus, big bonus (1) or big bonus (2)) is set in the winning flag storage work by internal lottery, the value corresponding to the special role with the winning flag set is the special role Written to temporary storage work. If data indicating the winning of a special role (that is, data other than 0) is written in the special role temporary storage work in the normal gaming state or RT, the special role lottery is not performed, and the contents can be rewritten. Absent. In this case, a regular bonus winning flag, a big bonus (1) winning flag, or a big bonus (2) winning flag is set in the winning flag storing work in accordance with the value of the special role temporary storing work.

  Even if data indicating the winning of any special role is written in the special role temporary storage work, regular bonus + watermelon, big bonus (1) + watermelon, big bonus (2) + watermelon Although the number of judgment values is acquired, in practice, only the watermelon is a lottery target and the contents of the special combination temporary storage work are not updated. The data of the special combination temporary storage work is cleared to 0 when the special combination is won.

  Even in the small role game, the number of determination values of regular bonus + watermelon, big bonus (1) + watermelon, big bonus (2) + watermelon is acquired, but only watermelon is actually a lottery target role. Also, in the small role game, JACIN may be elected as a special role and 4 corresponding to JACIN may be written in the special role temporary storage work. The special role temporary storage work data will be cleared.

  Further, when the winning flag of the general combination (small role or replay) is set in the winning flag storing work by the internal lottery, a numerical value corresponding to the general winning set with the winning flag is written in the general winning temporary storing work. The data of the temporary role temporary storage work is overwritten and updated for each game according to the winning flag of the general role set in the middle byte and lower byte of the winning flag storage work according to the result of the internal lottery in each game. Become. That is, data corresponding to the result of the internal lottery in the previous game is not written here.

  In the index search work, the data of the special role temporary storage work is written in the upper 4 bits, and the data of the general role temporary storage work is written in the lower 4 bits. It corresponds to the data of the flag storing work as it is. When creating a stop control table, which will be described later, a table index stored in the ROM 113 is referred to in accordance with index search work data.

  The winning flag storing work has the same configuration as the winning flag storing work, and when the display mode of the winning combination is derived on any winning line as the display result of the variable display device 2, it corresponds. A winning flag is set. Again, the winning flag is set when the corresponding bit changes from 0 to 1. For example, when a symbol combination of “BAR-BAR-BAR” is derived on any winning line, a regular bonus winning flag is set in the winning flag storing work. When the symbol combination “cherry-ANY-cherry” is derived, the cherry A winning flag is set in the winning flag storing work.

  When the winning flag is set in the winning flag storing work, it is determined whether or not there has been an illegal winning of a winning combination using the winning flag storing work data and the winning flag storing work data. Specifically, all the data of each bit of the winning flag storing work is logically inverted, and this and the data of the winning flag storing work are logically calculated for each bit. If the result of the logical product operation is 0, it is determined that there has been no illegal winning, and if it is not 0, it is determined that an illegal winning has occurred.

  For example, consider a case where a replay symbol is derived on a winning line in a state where the regular bonus winning flag and the replay winning flag are set. The data of the winning flag storing work before the logic inversion is “10000000 10000000 00000000”. The data of the winning flag storing work after examining the display result of the variable display device 2 is “00000000 10000000 00000000”, and “01111111 01111111 11111111” obtained by logically inverting the data of the winning flag storing work is logically calculated for each bit. Then, the result is “00000000 000000000 00000000”, which indicates that no illegal winning has occurred.

  Further, consider a case where a regular bonus symbol is derived on the winning line in a state where only the replay winning flag is set. The data of the winning flag storing work before the logic inversion is “00000000 10000000 00000000”. The data of the winning flag storing work after examining the display result of the variable display device 2 is “10000000 00000000 00000000”, and “11111111 01111111 11111111” obtained by logically inverting the data of the winning flag storing work is logically calculated for each bit. Then, the result is “10000000 00000000 00000000”, which indicates that an illegal prize has occurred.

  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. The internal winning status is not determined according to the winning flag setting work shown in FIG. 8A, but is determined according to the index search work shown in FIG. That is, the head address of the area where the table creation data is stored is registered in association with the value that the index search work data can take.

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

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

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

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

  When any one of the reels 3L, 3C, 3R stops or when any two stop, the top address obtained at the start of reel rotation, that is, the internal winning status in the game, that is, the index search work The table creation data is identified based on the head address of the table creation data according to the data, and the stopped reel and the unreserved reel pull-in corresponding to the area number of the stop position of the reel are identified from the identified table creation data The address of the frame number data is acquired, the drawing frame number data of each reel stored at the acquired address is expanded, and a stop control table is created for the unstopped reel.

  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 first address of the storage area of the table creation data corresponding to one internal winning situation, that is, one data of the index search work. In the creation data, only one address is stored as the address of the storage area for the number of drawn frame data corresponding to the stop status of one reel (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. That is, the symbol stop position can be designated from a range of up to five frames including the stop operation position at which 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 the case of a table index, when multiple types of small roles are simultaneously won (Cherry A to Cherry G, Cherry B to Cherry G in a gaming state other than the regular bonus, watermelon bell + watermelon in the regular bonus, etc.) Of the selected small roles, the most advantageous small role for the player (watermelon with a large number of medals to be paid out, cherry A with RT added (the number of medals paid out is large in comparison with the number of medals paid out and RT) The number of frames to be drawn is determined so that it can be pulled in as much as possible in the range of 4 frames, and the most advantageous small roles cannot be pulled in the range of up to 4 frames. As for the position, the number of frames to be drawn is set so that the other types of small roles (Cherry B to Cherry G, watermelon) are drawn to the maximum in the range of 4 frames. Address Le generation data is stored, the stop control of the reels 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.

  For example, the reel control when the cherries A to G are elected will be described in detail. When the symbols No. 1 and No. 21 to No. 13 are positioned on the lower reel 3L, the stop operation is performed. In this case, the pull-in control is performed so that the “cherry” of No. 13 or No. 18 is stopped at the upper stage or the lower stage. With respect to the right reel 3R, pull-in control is performed so that the “cherry” of No. 1, 8, or 15 stops at the upper stage or the lower stage regardless of the stop operation timing. The reel control when the cherry B to the cherry G are won is the same as that for the left reel 3L when the cherry A to the cherry G are won, but the right reel 3R is related to the stop operation timing. The kick control is performed so that the “cherry” of No. 1, 8 or 15 does not stop at the upper or lower level.

  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. Command, reel rotation command sent when the rotation of the reels 3L, 3C, and 3R starts, reel stop command sent when the rotation of the reels 3L, 3C, and 3R stops, and the display result is derived to the variable display device 2. There is a winning information command sent after being played, and a gaming state command sent after the end of one 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 reel rotation command indicates the start of reel rotation. The reel stop command indicates the type of reel that has been stopped and the derived symbol. The winning information command indicates the presence / absence of a winning and the type of winning. The gaming state command is a gaming state applied in the next game (normally, RT, second RT, regular bonus (until a small bonus game in a big bonus or not), a small bonus game in a big bonus) It 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 executed by the control of the CPU 121, particularly an effect performed on the liquid crystal display 4, an effect of deriving a display mode corresponding to a symbol derived to the variable display device 2 due to a change / stop of the virtual reel, and a regular There are announcements and notices of winning of bonus, big bonus (1) or big bonus (2).

  The virtual reel has, for example, symbols such as “BAR”, “7”, “JAC”, “watermelon”, “bell”, “cherry” in a predetermined arrangement (different from the arrangement of the symbols on the reels 3L, 3C, and 3R). Three arranged ones are displayed corresponding to the reels 3L, 3C, 3R of the variable display device 2. The virtual reels start to change when the reels 3L, 3C, and 3R start to rotate, and stop changing when the reels 3L, 3C, and 3R stop rotating. However, the stop of the virtual reel is not limited by the maximum stop delay time of 190 milliseconds like the reels 3L, 3C, and 3R of the variable display device 2.

  The virtual reels of the liquid crystal display 4 also display symbols in three stages, upper, middle and lower. However, there are a total of five pay lines indicating whether or not the virtual reel is in a winning display mode, one in each of the upper, middle, and lower horizontal directions and two on the diagonal lines. Such a form of winning line is the form most often used as a winning line for variable display devices other than the slot machine 1 according to this embodiment. In the virtual reel of the liquid crystal display 4, a symbol corresponding to the symbol derived to the winning line of the variable display device 2 is derived on any of the winning lines.

  For example, “JAC” is aligned on the virtual reel winning line when the JACIN winning and the replay winning are determined according to the display result of the variable display device 2. These are not missed, and even if the replay and regular bonus, big bonus (1) or big bonus (2) are duplicated, replay will be given priority, so win the JACIN or replay with the winning status notification command. In this case, the symbol to be derived can be determined in advance, and the stop of the virtual reel can be controlled. Similarly, when the design of the symbol derived to the variable display device 2 is determined regardless of the operation timing of the stop buttons 12L, 12C, 12R, the symbol to be derived is determined in advance, and the virtual reel is stopped. Can be controlled.

  When a watermelon or bell is won, “watermelon” and “bell” are aligned on the virtual reel winning line. Even when winning the watermelon bell, "watermelon" is aligned on the virtual reel winning line. In the case of overlapping winning with the regular bonus, the big bonus (1) or the big bonus (2), it is determined in advance that the “bell” and “7” or “BAR” are double-tempered, and the variable display device 2 The symbol may be derived on the virtual reel in accordance with the symbol stopped on the third reel. When any of Cherry A to Cherry G is won, “Cherry” is led to the left virtual reel. Regardless of which of Cherry A to Cherry G is won, an arbitrary symbol is derived on the middle and right virtual reels.

  When the regular bonus is won based on the display result of the variable display device 2, “BAR” is aligned on the winning line of the virtual reel. When winning the big bonus (1) or the big bonus (2), “7” is aligned on the winning line of the virtual reel. When the regular bonus, the big bonus (1), or the big bonus (2) is won, the stop of the virtual reel is controlled according to the symbols actually stopped for the reels 3L, 3C, 3R.

  By the way, when a bell or replay is won in a normal gaming state or RT, it is possible to win these roles without missing them. The chances of winning a missed watermelon, Cherry A to Cherry G, Cherry B to Cherry G are low, and the probability of winning a regular bonus, big bonus (1) or big bonus (2) is also low. Therefore, in the normal gaming state and RT, the player presses the stop button 12L, 12C, 12R to operate (stop operation is performed at a timing according to the symbols displayed on the rotating reels 3L, 3C, 3R. There is little need to do).

  When the cherry A to the cherry G or the cherry B to the cherry G are elected, in order to derive “cherry” for the left reel 3L, it is necessary to push the operation of the stop button 12L. There is no need to push the reel 3R. For the regular bonus, the big bonus (1), or the big bonus (2), it is necessary to make an eye on any of the reels 3L, 3C, and 3R. It is enough to do when done.

  As long as there is no need to push the game, the player only needs to know what role he has won as a result, so that even if he only looks at the virtual reel, the game can proceed sufficiently. Become. Even if a bonus announcement or bonus notice is made, it is sufficient to perform only the left reel 3L, and only the display mode of the left reel 3L can be any of Cherry A to Cherry G. I know I won, but I don't know if I won Cherry A. Therefore, in order to advance the game in the slot machine 1, the player has to watch only the left reel 3L in addition to the virtual reel.

  Even if the display mode of cherry A is derived to the variable display device 2 as a result of stopping the right reel 3R, the display mode of the symbols derived to the virtual reel is the same as when cherry B to cherry G are derived. Therefore, it is easy for the player to miss the derivation of cherry A in the variable display device 2. The number of medals to be paid out does not change between Cherry A and Cherry B to Cherry G, and the control to RT is only internal. For this reason, the cherry A is derived to the variable display device 2, and the player can easily overlook that the gaming state is controlled to RT.

  Next, bonus notification and bonus notice will be described. 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.

  When the gaming state is RT, the notice determination lottery is not performed, and only the notice determination lottery is performed. That is, no bonus notification is made while the gaming state is at RT. When a regular bonus, a big bonus (1), or a big bonus (2) is won in RT, a bonus notification is made in the game in which the 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. 11 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 process proceeds to the RAM abnormality error process 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. 12 (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. 12 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. 11, the game can be progressed and the game control process is started.

  FIG. 13 is a flowchart showing in detail the RAM abnormality error process executed by the CPU 111 of the game control board 101. In the RAM abnormality error process, the payout display 51 is controlled to display the RAM abnormality error code on the payout display unit 21 (step S301), and then the process proceeds to a loop process in which no process is performed.

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

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

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

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

  FIG. 14 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. 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. 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. 15 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.

  When an overflow occurs, it is determined whether or not the lottery target combination read in the immediately preceding step S504 is any of regular bonus + watermelon, big bonus (1) + watermelon or big bonus (2) + watermelon ( Step S512). In the case of regular bonus + watermelon, big bonus (1) + watermelon or big bonus (2) + watermelon, it is determined whether or not the current gaming state is a small role game (step S513).

If it is not in the small role game, whether the value of the special role temporary storage work is 0, that is, the regular bonus winning flag, big bonus (1) winning flag, or big bonus (2) winning flag from the previous game It is determined whether it has been carried over (step S514). If the value of the special combination storing work is 0, the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is set in the winning flag storing work in accordance with the read lottery target combination. A watermelon winning flag is set in the winning flag storing work (step S515). Then, the process proceeds to step S520.

  If the current gaming state is the small role game in step S513, or if the value of the special role temporary storage work is not 0 in step S514, only the watermelon winning flag is set in the RAM 112 (step S516). Then, the process proceeds to step S520.

  If the lottery target is neither regular bonus + watermelon, big bonus (1) + watermelon or big bonus (2) + watermelon in step S512, the lottery target is regular bonus, big bonus (1) or big It is determined whether the bonus is (2) (step S517). If it is any of the regular bonus, the big bonus (1), or the big bonus (2), it is determined whether or not the value of the special role temporary storage work is 0 (step S518).

  If the value of the special combination temporary storage work is not 0, the process proceeds to step S520 as it is. If the lottery target in step S517 is neither a regular bonus, a big bonus (1), or a big bonus (2), or if the value of the special feature temporary storage work is 0 in step S518, the winning flag of the lottery target is set. Set to winning flag storage work. Here, if the winning combination is Cherry A to Cherry G, seven winning flags of Cherry A, Cherry B, Cherry C, Cherry D, Cherry E, Cherry F, and Cherry G are set in the winning flag storing work. If it is Cherry B to Cherry G, six winning flags of Cherry B, Cherry C, Cherry D, Cherry E, Cherry F, and Cherry G are set in the winning flag storing work. If it is watermelon bell + watermelon, or watermelon bell + bell, a watermelon winning flag or a bell winning flag is set on top of the watermelon bell winning flag. If it is watermelon bell + cherry A to cherry G, the eight winning flags of watermelon bell winning flag, cherry A, cherry B, cherry C, cherry D, cherry E, cherry F and cherry G are set in the winning flag storing work (step) S519). Then, the process proceeds to step S520.

  In step S520, the middle byte and the lower byte of the winning flag storing work, that is, the value corresponding to the setting state of the winning flag of the general winning is stored in the general winning temporary storing work. Next, it is determined whether or not the upper byte of the winning flag storing work is 0, that is, whether or not any of the regular bonus, the big bonus (1) and the big bonus (2) is won in this game ( Step S521). If the upper byte of the winning flag storing work is not 0, the upper byte of the winning flag storing work, that is, a value corresponding to the setting status of the winning flag of the special role is stored in the special role temporary storing work (step S522). Then, the process proceeds to step S525.

  If the upper byte of the winning flag storing work is 0, whether or not the value of the special role temporary storing work is 0, that is, the regular bonus winning flag, big bonus (1) winning flag or big bonus (2 from the previous game) ) It is determined whether or not the winning flag has been carried over (step S523). If the value of the special role temporary storage work is not 0, the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is set in the higher byte of the winning flag storing work according to the value ( Step S524). Then, the process proceeds to step S525. If the value of the special role temporary storage work is 0, the process proceeds to step S525 as it is.

  In step S525, the special combination temporary storage work value is written in the accumulator. The value stored in the special role temporary storage work is written in the accumulator of the CPU 111. Further, the value of the lower 4 bits of the accumulator is shifted to the upper 4 bits (step S526). Next, the value stored in the general role temporary storage work is added to the value stored in the accumulator, and this is stored in the accumulator (step S527). Then, the value stored in the accumulator is stored in the index search work (step S528).

  Furthermore, a winning status notification command is generated according to the setting status of the winning flag of each combination indicated by the winning flag storage work or the index search work, and is transmitted to the effect control board 102 (step S529). 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. 16 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 S403 will be described in detail. FIG. 17 is a flowchart showing in detail the reel rotation process executed by the CPU 111 in step S403. 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). At this time, a reel rotation command indicating that the reels 3L, 3C, 3R have started to rotate is generated and transmitted to the effect control board 102 (step S704).

  After that, referring to the table index corresponding to the value of the index search work, the table creation data is specified, and the game state of the game, the internal winning status, and the stop of other reels based on the specified table creation data A stop control table corresponding to the situation is created for each rotating reel (step S705). In addition, the work initialization code at the completion of the stop preparation is set in the register (step S706). Thereby, the operation of the stop buttons 12L, 12C, and 12R becomes valid.

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

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

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

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

  Thereafter, the process waits until the rotation of the reel (any one of 3L, 3C, and 3R) corresponding to the operated stop button stops (step S717). Then, when the rotation of the reel (3L, 3C, 3R) corresponding to the operated stop button is stopped, it is determined whether all of the reels 3L, 3C, 3R are stopped (step S718). If the rotation of the reels 3L, 3C, 3R is not stopped, the process returns to step S705. If the rotation of all the reels 3L, 3C, 3R is stopped, the reel rotation process is terminated and the process returns to the flowchart of FIG.

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

  Next, the winning determination process in step S405 will be described in detail. FIG. 18 is a flowchart showing in detail the winning determination process executed by the CPU 111 in step S405. In the winning determination process, a winning flag corresponding to the role symbol derived on any winning line of the display result of the variable display device 2 is set in the winning flag storing work of the RAM 112. For example, when the regular bonus symbols are arranged on the winning line of the variable display device 2, the value of the most significant bit of the upper byte of the winning flag storing work becomes 1, and the values of the other bits become 0 (step) S801).

  Next, the value of each bit of the winning flag storing work in the RAM 112 is inverted. For example, when only the regular bonus winning flag is set, the value of the most significant bit of the upper byte of the winning flag storing work is 0, and the values of the other bits are 1. Then, the data of the winning flag storage work and the data of the winning flag storage work are logically ORed for each bit (step S802). Then, it is determined whether or not the result of the logical sum operation in step S802 is 0 (step S803).

  If the result of the logical sum operation in step S802 is not 0, it means that a winning combination for which the winning flag has not been set has been won. In this case, the routine proceeds to predetermined error processing. Since this error processing is not directly related to the present invention, detailed description thereof is omitted.

  If the result of the logical sum operation in step S802 is 0, it is determined whether or not a replay winning is made based on whether or not a replay winning flag is set in the winning flag storing work (step S804). If a replay prize has been won, a replay game flag is set in the RAM 112 (step S805). 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 S817.

  If no replay winning is made, it is determined whether or not the big bonus (1) is won depending on whether or not the big bonus (1) winning flag is set in the winning flag storing work (step S806). If the big bonus (1) is won, the big bonus medium flag is set in the RAM 112, and the value of the special combination temporary storage work is initialized to zero. Further, the RT counter value of the RAM 112 is initialized to 0 (step S807). Then, the process proceeds to step S817.

  If the big bonus (1) has not been won, it is determined whether or not the big bonus (2) has been won based on whether or not the big bonus (2) winning flag is set in the winning flag storing work (step S808). If a big bonus (2) has been won, a big bonus medium flag is set in the RAM 112, and the value of the special combination temporary storage work is initialized to zero. Further, the RT counter value of the RAM 112 is initialized to 0 (step S809). Then, the process proceeds to step S817.

  If the big bonus (2) is not won, it is determined whether or not the regular bonus is won based on whether or not the regular bonus winning flag is set in the winning flag storing work (step S810). If a regular bonus has been won, a regular bonus medium flag is set in the RAM 112 and the value of the special combination temporary storage work is initialized to zero. Further, the RT counter value of the RAM 112 is initialized to 0 (step S811). Then, the process proceeds to step S817.

  If there is no regular bonus winning, it is determined whether or not a JACIN winning is made according to whether or not a JACIN winning flag is set in the winning flag storing work (step S812). If a JACIN prize has been won, the regular bonus medium flag is set in the RAM 112, and the value of the special role temporary storage work is initialized to 0 (step S813). Then, the process proceeds to step S817.

  If no JACIN winning has been made, it is determined whether or not the Cherry A winning has been made, depending on whether or not the Cherry A winning flag is set in the winning flag storing work (step S814). If the Cherry A prize has been won, neither the regular bonus flag nor the big bonus flag is set in the RAM 112, and the gaming state in the current game is normal depending on whether the RT counter value of the RAM 112 is 0 or not. It is determined whether or not the gaming state is (step S815).

  If the game state in the current game is a normal game state, 101 is set as the initial value of the RT counter in the RAM 112. Here, to set 101 as the initial value, the RT counter value is decremented by 1 in step S912 (described later) until the next game is started. This is to secure 100 games (step S816). Then, the process proceeds to step S817. If no replay winning is made, the process proceeds to step S817.

  In step S817, the type of winning combination based on the winning flag set in the winning flag storing work (however, the winning flag is not set in case of losing) and the number of medals to be paid out in accordance with the winning are determined. A winning information 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. 19 is a flowchart showing in detail the payout process executed by the CPU 111 in step S406. In the payout process, it is determined whether or not there has been a small role winning accompanied by paying out medals depending on whether or not any of the watermelon, bell, and cherry winning flags is set in the winning flag storing work (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 S907.

  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 S907.

  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). ). Then, the process proceeds to step S910.

  In step S907, it is determined whether or not the game state of the game is a regular bonus (including a case where a big bonus is provided) depending 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 S908). As a result of this count, it is determined whether the number of winning games in the regular bonus has reached 8 or the number of digested games in the regular bonus has reached 12 (step S909).

  When 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 S910. If the number of winning games in the regular bonus is not eight and the number of digest games in the regular bonus is not twelve, the process proceeds to step S913. In step S910, the regular bonus flag set in the RAM 112 is erased, and the counter values 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 S913.

  If the game state of the game is not a regular bonus in step S907, it is determined whether the RT counter value in the RAM 112 is 0 (step S911). If the RT counter value is not 0, the RT counter value is decremented by 1 (step S912), and the process proceeds to step S913. If the value of the RT counter is 0, the process proceeds to step S913 as it is.

  In step S913, the winning flag set in the winning flag storing work and the winning flag set in the winning flag storing work are all erased. This process is realized by a process of clearing the general work 112-2 for each game. In this game, the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is set and the regular bonus, big bonus (1) or big bonus (2) is not won. Even if the special bonus temporary storage work value is not cleared, the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is carried over to the next game. On the other hand, since the value of the general combination temporary storage work is always rewritten according to the result of the internal lottery of the next game, the winning combination flag of the general combination is not carried over to the next game.

  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 S914). Then, the payout process is ended, and the process returns to the flowchart of FIG. Here, when returning to the flowchart of FIG. 14, the process in the current one game ends.

  In the repetition of the game as described above, the CPU 111 of the game control board 101 shifts the game state among the normal game state, RT, big bonus, and regular bonus, and issues a command according to the progress of the game. It is transmitted to the production control board 102. On the other hand, the CPU 121 of the effect control board 102 performs an original effect in which the game state includes a variable display of symbols by virtual reels based on the command received from the game control board 101. Hereinafter, the process of the effect performed by the control on the effect control board 102 side will be described.

  FIG. 20 is a flowchart showing 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 S529, 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 make a bonus announcement 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 RT. In any case, no bonus announcement is made. That is, when the gaming state is controlled to 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 reel rotation command transmitted in step S705, first, the symbol display mode in the variable display device 2 stored in the RAM 122 based on the reel stop command received in the previous game is displayed. The indicated information is cleared (step S1012). Further, the virtual reel is displayed on the liquid crystal display 4, and the symbol variation display by the virtual reel is started (step S1013). Then, the process returns to step S1001.

  If the received command type is a reel stop command transmitted every time the rotation of the reels 3L, 3C, 3R is stopped in step S716, the command is derived to the reels 3L, 3C, 3R indicated by the reel stop command. Information indicating the displayed symbol is stored in a predetermined area of the RAM 122 (step S1014). Furthermore, referring to the information indicating the setting status of the winning flag stored in the RAM 122 and the information indicating the stop status of the reels 3L, 3C, 3R, any one of the three is selected according to the stopped reels 3L, 3C, 3R. The virtual reel is stopped, and a symbol corresponding to the symbol derived to the variable display device 2 is derived to the virtual reel (step S1015). Then, the process returns to step S1001.

  If the received command type is the winning information command transmitted in step S817, the winning information indicated by the received winning information command is stored in the RAM 122 (step S1016). 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. The effect LED75A-75M is turned on and the reel lamp 3LP is turned on, for example, an effect determined according to the type of winning combination is executed (step S1017).

  Next, it is determined whether or not a bonus notification is performed on the liquid crystal display 4 based on whether or not a notification flag is set in the RAM 122 (step S1018). 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 S1019).

  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 S1020). 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 S1030, it is determined whether or not the bonus notification is performed on the liquid crystal display 4 depending on whether or not the notification flag is set in the RAM 122 (step S1021). 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 S1022). Then, the process returns to step S1001. If no bonus announcement is made, the process returns to step S1025.

  If the received command type is the gaming state command transmitted in step S914, 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 gaming states, the previous gaming state is shifted to store the gaming state indicated by the currently received gaming state command (step S1023).

  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 RT has ended for the current game only (step S1024). If the RT is not ended for the current game, that is, if the RT has not already been reached from the previous game, or if the RT continues in the next game, the process returns to step S1001.

  If RT is over for the current game, it is determined whether or not the winning status stored in step S1003 indicates winning of regular bonus, big bonus (1) or big bonus (2) (step S1003). S1025). If any of the regular bonus, the big bonus (1), and the big bonus (2) is not indicated, the process directly returns to step S1001.

  If the winning of the regular bonus, the big bonus (1), or the big bonus (2) is shown, the liquid crystal display 4 gives a bonus notification. In addition, a notification flag indicating that the bonus notification has already been performed is set in the RAM 122 (step S1026). 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 S1027). Thereafter, the process returns to step S1001.

  As described above, in the slot machine 1 according to this embodiment, when winning a cherry A in the normal gaming state, the gaming state is controlled to RT. The gaming state of RT continues for 100 games unless a regular bonus, a big bonus (1) or a big bonus (2) is won. However, any information that can specify that the gaming state is controlled to RT is not notified to the player other than the display mode of the cherry A being derived to the variable display device 2.

  The result of each game in the slot machine 1 is shown by the display mode derived to the variable display device 2 composed of the reels 3L, 3C, 3R. The display mode corresponding to the display mode of the variable display device 2 Is also indicated by a virtual reel displayed on the liquid crystal display 4. The liquid crystal display 4 is larger than the variable display device 2 and is close to the height of the player's line of sight and easily visible.

  Here, in order to stop the reels 3L, 3C, and 3R constituting the variable display device 2, there is a restriction that the reels 3L, 3C, and 3R must be stopped within a range of a maximum stop delay time of 190 milliseconds from the operation of the stop buttons 12L, 12C, and 12R. Although imposed, such a restriction is not imposed on the stop of the virtual reel displayed on the liquid crystal display 4. For this reason, when stopping the virtual reel of the liquid crystal display 4, it becomes possible to perform various effects impossible when stopping the reels 3L, 3C, and 3R of the variable display device 2, and to improve the entertainment of the game. Can do.

  By the way, in the slot machine 1 according to this embodiment, the bell and the replay are not missed. In order to win Cherry A to Cherry G, it is necessary to push the left reel 3L. However, among Cherry A to Cherry G, right reel 3R to win Cherry A with control to RT. You don't have to hold on. Since the winning probability of regular bonus, big bonus (1), and big bonus (2) that require attention to all reels 3L, 3C, 3R is low, bonus announcements and bonus notices may be issued in gaming states other than regular bonus Except for the case where the game is played, the game can be advanced with almost no pressing except for the left reel 3L. In addition, since the display mode corresponding to the display result of the variable display device 2 is derived from the virtual reel of the liquid crystal display 4, it is not necessary to see the variable display device 2 itself except for the left reel 3L.

  On the other hand, when the display mode of cherry A that triggers the control of the gaming state to RT is derived to the variable display device 2, the display mode derived to the virtual reel of the liquid crystal display 4 is cherry B to cherry G. There is no difference from the combination of symbols derived to the virtual reel when the display mode is derived, and there is no effect indicating that it is controlled by RT. For this reason, it is possible to prevent the player from noticing the display mode of the cherry A to the variable display device 2, and to prevent the RT control from being perceived. In addition, the number of medals paid out does not change when winning Cherry A or when winning Cherry B to Cherry G. Depending on the number of medals paid out, whether it is Cherry A or Cherry B to Cherry G Can not be distinguished from each other, and control to RT can be prevented from being detected.

  Moreover, the display mode of the cherry A displayed on the variable display device 2 is also different from the display modes of the cherry B to the cherry G only in the symbols derived to the right reel 3R. The number of medals to be paid out is the same. Even when the display mode derived to the variable display device 2 is viewed, even if the derivation of “cherry” to the left reel 3L, which has been required to be pressed, can be recognized. Unless the difference in the symbols derived to the right reel 3R can be recognized, the player only knows the derivation of the display mode of Cherry A to Cherry G, and does not know the derivation of the display mode of Cherry A. Regardless of the cherry A or the cherry B to the cherry G, there is no limitation on the design of the reel 3C.

  In many conventional slot machines, the symbol “cherry” is derived on the left reel 3L, so that the role that becomes a small role prize regardless of the type of symbols derived on the middle and right reels 3C, 3R. Has been applied. For a player accustomed to playing with such a conventional slot machine, it is difficult to distinguish between cherry A and cherry B to cherry G, which have a common symbol of “cherry” on the left reel 3L. The fact that any of Cherry A to Cherry G does not matter what kind of design of the reel 3C in the inside is rich in the types of display modes and is common with the conventional slot machine, so Cherry A and Cherry B ~ Makes it difficult to distinguish from Cherry G. For this reason, even when the cherry A is derived as the display result of the variable display device 2, it is difficult for the player to understand, so that it is difficult to perceive the control to RT.

  When the gaming state is controlled to RT by winning Cherry A, the replay winning probability increases and replay winning frequently occurs. Therefore, the player can derive the display mode of Cherry A on the variable display device 2. Even if you missed it, you can imagine that the gaming state is in RT. If it is considered that the player can recognize only the derivation of the cherry to the virtual reel of the liquid crystal display 4 (or the derivation of the “cherry” symbol to the left reel 3L), the cherry is derived to the virtual reel. (Alternatively, the “cherry” symbol is derived to the left reel 3L), and the RT lottery is performed. As a result, an impression that the gaming state is controlled to RT can be given to the player. Can improve the interest of

  Further, even though the cherry A that triggers the control of the gaming state from the normal gaming state to the RT is derived in preference to the cherry B to the cherry G, the left reel is dependent on the operation timing of the stop button 12L. Since 3L cannot let “cherry” be derived, it may be missed even if it is won. For this reason, technical intervention is not spoiled with respect to control to RT, and the interest of a game can be improved further. Since it is not necessary to perform the RT transfer lottery separately, the processing load does not become too large.

  In the internal lottery, seven types of cherry A to cherry G or six types of cherry B to cherry G are subject to lottery at the same time, but the winning flags in the winning flag storage work are cherry A, cherry B, cherry C, Cherry D, Cherry E, Cherry F, and Cherry G are set separately. For example, when Cherry A to Cherry G are won, seven of the Cherry A winning flag, Cherry B winning flag, Cherry C winning flag, Cherry D winning flag, Cherry E winning flag, Cherry F winning flag and Cherry G winning flag The winning flag is set. On the other hand, the winning flags set for the winning flag storing work are also separately determined for each of Cherry A, Cherry B, Cherry C, Cherry D, Cherry E, Cherry F, and Cherry G.

  For example, in the case of designing a new slot machine by using the specifications of the slot machine 1 according to this embodiment by setting different winning flags and different winning flags for different display modes in this way. Even in the case where only the cherry A is determined as a winning combination and the cherry B to the cherry G are not determined as winning combinations in the new slot machine, the design can be easily changed. Only when “cherry” is derived to the left reel 3L, the winning of the cherry is won, and even in the slot machine where the RT control is not related to this, deletion of the portion where the cherry B to cherry G are subject to the lottery and the cherry A The design can be changed simply by deleting the part controlled by RT.

  On the other hand, as described in JP-A-6-327809, a winning flag common to different display modes is determined (in this embodiment, a common winning flag for cherry A to cherry G and a cherry B-Cherry G will have a common winning flag), but only the cherry A will be changed, although there are relatively few changes in the case of winning the cherry only because "cherry" is derived to the left reel 3L. In order to determine as a winning combination, a significant design change is required.

  Further, in the slot machine 1 according to this embodiment, a winning flag storing work having the same form as the winning flag storing work is prepared in order to check whether or not an illegal winning of a combination having no winning flag set has occurred. In addition, a winning flag corresponding to a combination of symbols on the winning line of the variable display device 2 is set. Then, after logically inverting the data of the winning flag storing work, the logical product operation is performed for each bit of the winning flag storing work data. As a result, it is possible to easily determine the illegal winning.

  Here, since the contents of the winning flag storing work are rewritten by logically inverting the data of the winning flag storing work in order to determine the illegal winning, the winning flag storing work is provided in the general work 112-2. The data is cleared for each game, that is, all winning flags are erased for each game. However, although it is also used for selection of reel control, the winning of the regular bonus, the big bonus (1) or the big bonus (2) is written in the special combination temporary storage work that is not updated until the winning. As a result, the regular bonus winning flag, the big bonus (1) winning flag, and the big bonus (2) winning flag can be carried over until winning.

  Moreover, instead of erasing only the winning flags other than the regular bonus winning flag, the big bonus (1) winning flag, and the big bonus (2) winning flag for each game, the general work 112-2 including the entire winning flag storing work 112-2 Is cleared for each game. For this reason, it is not necessary to prepare the winning flag storage work across the general work 112-2 and other works in the RAM 112, and the prospect of the position where the winning flag storage work is placed at the time of design is improved. In addition, since it is not necessary to delete only the replay or small winning combination flag in units of bits, the processing becomes easy.

  In addition, in the slot machine 1 according to this embodiment, as an effect other than the display of the virtual reel, a bonus for definite notification that the regular bonus, the big bonus (1), or the big bonus (2) is won. A bonus announcement is made to notify 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.

  The gaming state of RT continues for 100 games unless a regular bonus, a big bonus (1) or a big bonus (2) is won. That is, the RT does not end only by winning the regular bonus, the big bonus (1), or the big bonus (2), so that the player does not lose the RT profit of the duration of 100 games. On the other hand, if the regular bonus, the big bonus (1), or the big bonus (2) is won when 100 games are consumed in RT, the bonus notification is always performed. As a result, in a game in which the 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.

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

  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. If you win JACIN, Bell, Watermelon or Replay, you will not miss it.

  In particular, when the gaming state is controlled by the regular bonus, including the case where watermelon, bell or cherry A to cherry G are both won, the watermelon bell is won with a probability of 100%. The watermelon bell is a role that cannot be missed, and is also a role that is preferentially derived even in the case of duplicate winning with watermelon, bell or cherry A to cherry G. Furthermore, the watermelon bell is a role having a larger number of medals at the time of winning than watermelon, bell or cherry A to cherry G, and when the gaming state is controlled by the regular bonus (the regular bonus is controlled in the big bonus). It is a role that cannot be won, that is, it is not possible to win.

  As a result, when the gaming state is controlled to the regular bonus, the player does not have to push at all, the game can be easily advanced, and the medals used for setting the bet number It becomes possible to receive a specified number of medals with a minimum amount. 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, the 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, Compared to 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 addition, the internal lottery adds the number of judgment values of each role referred from the role-specific table to the acquired random number for internal lottery, and depending on whether or not the result of the addition overflows, Judgment is made on whether or not there is a win. For this reason, an internal lottery can be performed using the number of determination values of each combination as it is. It should be noted that when the winning determination table is generated before the actual winning determination is made, the loop processing is required twice, but according to this embodiment, the loop processing in the lottery processing is only required once. Thus, the processing efficiency in the entire lottery process is high.

  In addition, the number of determination values in the normal gaming state or RT is registered for lottery for both the regular bonus, the big bonus (1), or the big bonus (2) and the watermelon. Here, if the regular bonus winning flag, the big bonus (1) winning flag, and the big bonus (2) winning flag are not carried over from the previous game, that is, if the value of the special role temporary storage work is 0, Depending on the value of the random number for internal lottery, both the regular bonus, the big bonus (1), or the big bonus (2) and the watermelon are won.

  Here, even if the winning combination of “watermelon” is won based on the display result of the variable display device 2 based on the watermelon winning flag set based on the winning of the watermelon that is one of the lottery 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. For this reason, even when winning a “watermelon” small role, the player can expect a regular bonus, a big bonus (1), or a 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-described embodiment, in addition to the symbols being variably displayed by the reels 3L, 3C, and 3R of the variable display device 2, the effect symbols are displayed by the virtual reels displayed on the liquid crystal display 4 provided more easily than this. The present invention has been described by taking the slot machine 1 that displays the information as a variable. Of course, the display modes of cherry A and cherry B to cherry G are relatively indistinguishable, and therefore, a variable display device having a size approximately equal to that of liquid crystal display 4 is provided at the position of liquid crystal display 4 It is good. There is no need to display a virtual reel. Even in this case, it is fully considered that the player misses the winning of the cherry A, so that the effect of the present invention can be obtained.

  In the above embodiment, two medals per payout line are paid out when winning a cherry A with control to RT or winning a cherry B to cherry G without control to RT. I was supposed to. However, the number of medals paid out when winning a cherry A and the number of medals paid out when winning a cherry B to a cherry G may be different. Here, in order to preferentially derive Cherry A when winning Cherry A to Cherry G, the number of medals paid out when winning Cherry A is the same as when winning Cherry B to Cherry G. What is necessary is just to make it more than the number of medals paid out.

  When the number of medals paid out when winning a cherry A and the number of medals paid out when winning a cherry B to cherry G are different, the former is two and the latter is one. Is preferred. In this case, when winning the cherry A, the player simultaneously wins one of the cherry B to the cherry G, and a total of three medals are paid out. On the other hand, when two cherries B to G other than Cherry A are won, a total of two medals will be paid out. In the normal gaming state, three medals are consumed for setting the bet number, so the maximum number of credits accumulated at the start of the game is 47. Regardless of whether the number of medals to be paid out is 3 or 2, it is only accumulated in credits, and medals are not discharged outside the slot machine 1. This is because it is possible to make it difficult for the player to notice the prize.

  In the above embodiment, since the “cherry” symbols are arranged at intervals of 7 frames for the right reel 3R, when the cherry A to the cherry G are selected, the “reel” is displayed regardless of the operation timing of the stop button 12R. As long as the "cherry" symbol can be stopped at the upper or lower stage and "cherry" can be derived for the left reel 3L, the cherry A will always be won. However, the symbol arrangement on the right reel 3R may include a place where the symbol “cherry” is arranged in eight frames or more.

  Here, when the cherry A to the cherry G are won, if the “cherry” can be stopped at the upper or lower stage according to the operation timing of the stop button 12L, the “cherry” is assumed to be derived for the left reel 3L. As long as “A” can be derived. If “cherry” cannot be derived for the right reel 3R, the other symbols are stopped at the upper and lower tiers of the right reel 3R, and two of Cherry B to Cherry G are awarded. be able to.

  In this case, even if two of Cherry B to Cherry G were won, Cherry A to Cherry G were won, and if Cherry A that was won was missed, Cherry A was not won in the first place Since the player does not know this, the interest of the game can be further improved. However, if the cherry A is won, the cherry A is derived with priority over the cherry B to the cherry G, so that the reel control becomes easy and the player is not damaged.

  In the above embodiment, the display mode of cherry (Cherry A) with RT transition is “Cherry-ANY-Cherry”, and the display mode of cherry (Cherry B to Cherry G) without RT transition is “Cherry”. -ANY-BAR / 7 / JAC / Replay / Watermelon / Bell "(" / "indicates the symbols corresponding to Cherry B to Cherry G, respectively). On the other hand, the cherry display mode with RT transition is “Cherry-ANY-Cherry / BAR” (Replay A, Replay B), and the cherry display mode without RT transition is “Cherry-ANY-7 / JAC / Replay / Watermelon / Bell ”(Replay C to Replay G) may be used. In this case, there may be a case where Replay A to Replay G are the lottery targets and a case where Replay C to Replay G are the lottery targets.

  Further, the cherry display mode with RT transition may be “cherry-cherry-ANY”, and the cherry display mode without RT transition may be “cherry-BAR / 7 / replay / watermelon / bell-ANY”. The display mode of cherries with RT transition may be “ANY-Cherry-Cherry”, and the display mode of cherries without RT transition may be “BAR / 7 / Replay / Watermelon / Bell-ANY-Cherry”.

  Also, the cherry display mode with RT transition is “Cherry-Cherry-Cherry”, and the cherry display mode without RT transition is “Cherry-Cherry-BAR / 7 / JAC / Replay / Watermelon / Bell”. Also good. When “cherry” for the left and right reels 3L and 3R is shared by the cherry with RT transition and the cherry without RT transition, or “cherry” for the middle and right reels 3C and 3R Is also possible. The cherry display mode with RT transition is “Cherry-Cherry-Cherry”, and the cherry display mode without RT transition is “Cherry-BAR / 7 / Replay / Watermelon / Bell-BAR / 7 / JAC / Replay”. / Watermelon / bell ”.

  Of the reels 3L, 3C, and 3R, the specific 1 or 2 reels may or may not be accompanied by the transition of RT, and the display mode in which a specific type of symbol is derived is common. In one or two reels (or other one reel when two specific reels are used), the first type of symbols (multiple types) on the winning line from which the specific type of symbols is derived in the specific reel When it was derived), it became a small role with a transition to RT, and a second type of design different from the first type of design (not necessarily all the remaining types) was derived It only has to be a small role that is not accompanied by a transition to RT.

  In the case where two specific reels are used, different types of reels may be used for different types of small reels with different RT display modes. For example, when the left and middle reels 3L and 3C are applied as specific reels, the display mode of a small role with RT transition is “Cherry-Bell-Cherry”, and the display mode of a small role without RT transition is “Cherry-Bell-BAR / 7 / JAC / Replay / Watermelon / Bell” may be used. When there is one specific reel and the other two reels do not have a reel for winning a small role regardless of the type of symbols, the display mode of the small role with RT transition is different on the winning line. Different types of reels may be used. For example, when the left reel 3L is applied as a specific reel, the display mode of a small role with RT transition is “Cherry-Bell-Cherry”, and the display mode of a small role without RT transition is “Cherry-BAR”. / 7 / Replay / Watermelon / Cherry-BAR / 7 / JAC / Replay / Watermelon / Bell ”.

  In the above embodiment, except that the display mode of cherry A is derived to the variable display device 2, the player can be notified from the outside that the gaming state is controlled (controlled) by RT. There wasn't. On the other hand, after the gaming state is controlled to RT by winning a cherry A, it may be notified that the gaming state is controlled to RT when a predetermined condition is satisfied. Even when notifying that RT is controlled, it is preferable not to notify the number of remaining RT games (or the number of digested games).

  For example, the player may be notified that the gaming state is controlled by the RT when the replay winning (which is synonymous with the replay winning because there is no missing game) continues for three games in the gaming state of RT. The number of consecutive replay winnings as a condition for RT notification may be two games or four or more games. Furthermore, as long as the occurrence of the replay winning in the RT satisfies a predetermined condition, the replay winning may not be limited to the case where the replay winning is completely continuous.

  For example, in the case where only one game is not replayed, it may be intermittent replay that is not counted. For example, even when replay → non-replay → replay → non-replay → replay and winning are generated intermittently, the condition for performing RT notification can be set. Further, the condition for performing the RT notification may be a case where the number of replay winnings occurring during the recent predetermined number of games reaches a predetermined number. For example, if it is a condition that a replay winning has occurred in 3 out of 4 recent games, RT notification can be performed even when replay → replay → non-replay → replay. In such a case, the number of winning information games stored in the RAM 122 may be increased as necessary.

  When RT notification is to be performed based on such a replay winning history, even if the history to be determined is limited to the history after the gaming state is controlled to RT, before the RT is controlled. The history may be included. For example, assuming that the display result of the variable display device 2 is derived in the order of replay → replay → RT → replay on the condition that a replay win has occurred in 3 of the 4 latest games, the former case In the latter case, RT notification is not performed in the replay winning after the RT winning, but in the latter case, the RT notification is performed in the replay winning after the RT winning.

  Note that such determination of the replay winning history may be performed only when the RT is controlled, or may be performed regardless of whether the RT is controlled. In the latter case, after determining that the replay winning history satisfies the conditions set as an RT notification trigger, it is determined whether or not the gaming state is at RT, and if the RT is controlled, RT notification is performed. It should be.

  Furthermore, it may be notified that the gaming state is controlled to RT regardless of the occurrence of the replay winning. For example, as long as the CPU 121 of the effect control board 102 can be specified by a command sent from the game control board 101, it may be notified that the RT is controlled by the RT remaining game count being less than 20 games. . Furthermore, when the remaining RT game count is 20 or more and less than 50 games, RT notification is performed on the condition that the RT notification lottery is won, and when the remaining RT game count becomes less than 20 games, the RT notification is always performed. It is good. RT notification may be performed on condition that a lottery performed regardless of the number of remaining RT games is won. Here, the winning probability of the RT notification lottery may be changed according to the number of remaining RT games.

  If the number of RT games is fixed as in the above embodiment, using the RT remaining game number as a reference is synonymous with using the RT digest game number as a reference, but if the RT game number is variable, RT notification may be performed based on the number of remaining RT games, or RT notification may be performed based on the number of RT digested games. Furthermore, notification may be made when a winning combination and / or winning of a role other than replay satisfies a predetermined condition, such as the fact that the game is not lost continuously for three or more games. Winning and / or winning of a role other than replay may be combined with the number of remaining RT games or the number of RT digested games, and RT notification may be performed by combining lottery.

  Furthermore, a notification that the RT is controlled is given when three replay winnings are continued in the gaming state of RT (it may be replaced with another condition as described above; hereinafter the same in the description of this paragraph). When the replay winning is continued for 3 games in the normal gaming state, the rendition of the aspect similar to the notification that the RT is controlled is performed. As a final result, it may be notified that RT is not controlled. In this case, even if a replay win happens to happen in three games in the normal gaming state, the player can expect the gaming state to be controlled by RT by the production, and further improve the interest of the game Can be made.

  In the above embodiment, the number of RT continued games was 100 games (until a regular bonus, a big bonus (1) or a big bonus (2) was won). However, the number of continued games in RT is not limited to 100 games. The number of continued RT games is not limited to a fixed number of games, but may be a variable number of games determined by lottery, for example.

  In the above embodiment, a watermelon with a payout of 15 medals more than other small roles will be subject to internal lottery only when the gaming state is a regular bonus, and in the case of overlapping 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 bell. 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. For example, in the above embodiment, a watermelon bell may be applied instead of a watermelon as a lottery role in a gaming state other than the regular bonus. 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.

  In the above embodiment, in a game in which the game state is controlled to the regular bonus, the watermelon bell is always won, including the case where the game is won at the same time as the watermelon or the bell. 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 a watermelon alone. The watermelon bell 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 embodiment, the regular bonus, the big bonus (1) or the big bonus (2), and the watermelon are set as the lottery targets at the same time. Including this, the lottery for the special role such as the regular bonus, the big bonus (1) or the big bonus (2) and the lottery for the non-special role (small role, replay) are performed in the same flow. On the other hand, the lottery for special roles and the lottery for non-special roles may be performed separately.

  FIG. 21 is a diagram schematically showing a winning determination table applied in this modification. FIG. 22 is a flowchart showing in detail the 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. 21, 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. 21A, 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. 21 (a), the hatched range is a regular bonus, a big bonus (1) or a big bonus (2) and a watermelon 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 game state, when the regular bonus winning flag, big bonus (1) winning flag or 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 at RT, the internal lottery is performed by the same method as in the normal gaming state. However, in the small role table used in RT, the small game table in the normal gaming state is lost. The range of determination values that are won by replay is included in the range that overlaps the range that is lost in the bonus table. The bonus table is commonly used in the normal gaming state and 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. 21C and 21D, 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, and an internal lottery is performed. Is done.

  In the lottery process shown in FIG. 22, 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. 15). Further, the processing after the lottery result in the game is confirmed (steps S1114 to S1123) is the same as the processing of steps S520 to S529 in FIG.

  After obtaining a random number for internal lottery in step S1103, a small role winning determination table prepared according to the current gaming state (normal, RT, small bonus game, or regular bonus) and a set value is used for internal lottery. The winning determination table to be used is set (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 winning flag storing work. Here, when winning cherry A to cherry G, winning the cherry A winning flag, cherry B winning flag, cherry The C winning flag, cherry D winning flag, cherry E winning flag, cherry F winning flag and cherry G winning flag are set in duplicate. When the cherry B to the cherry G are won, the cherry B winning flag, the cherry C winning flag, the cherry D winning flag, the cherry E winning flag, the cherry F winning flag, and the cherry G 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 a normal gaming state or RT. In this case, it is determined whether or not the value of the special role temporary storage work is 0 (step S1109). If the value of the special role temporary storage work is not 0, the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag from the previous game will be carried over, so that the processing of step S1114 is performed as it is. move on.

  If the value of the special combination temporary storage work is 0, a bonus winning determination table corresponding to the set value is set as a winning determination table used for internal lottery (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 winning flag storing work (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 value for internal lottery corresponds to the value that is won for the special role in the normal gaming state or RT and is not When the special role (in this case, watermelon) corresponds to the winning value, 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 (here, a watermelon prize) based on a winning flag for a non-special role such as a small role or a replay, it is still special. There is a possibility that the role was also won. 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.

  Further, even if the special combination is not won as a result of the internal lottery, there is a possibility that the small combination or replay is won, so that the player's expectation can be maintained. Further, in the normal gaming state or RT, if the value of the special role temporary storage work is already 0 as a result of the internal lottery in the game before the previous time, both the small role winning determination table and the bonus winning determination table are both However, if the value of the special role temporary storage work is not 0, the internal lottery may be performed using only the small role winning determination table. As a result, the normal game state and the internal lottery in 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. Regardless of whether the value of the special role temporary storage work is 0 or not, a lottery is performed using both the small role winning determination table and the bonus winning determination table in the normal gaming state or RT. If the regular bonus, the big bonus (1), or the big bonus (2) is won when the value of the special role temporary storage work is not 0, 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. 23 is an explanatory diagram of a first modified example of processing (steps S503 and S1103) until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. Also in the first modification, the random number extracted from the random number generation circuit 115 is stored in the 16-bit general-purpose register 111GR included in the CPU 111.

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

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

  FIG. 24 is an explanatory diagram of a second modification of the process (steps S503 and S1103) until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. Also in this example, the random number extracted from the random number generation circuit 115 is stored in the 16-bit general-purpose register 111GR included in the CPU 111.

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

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

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

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

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

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

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

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

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

  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 1 or 2 is set as the number of bets in the small role game, normal gaming state, and RT, the winning probability of the small role in the internal lottery is lowered as compared with the case where 3 is set as the bet number. The number of medals to be paid out when winning a prize 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, 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, if the regular bonus medium flag is not set in the RAM 112 when the start lever 11 is operated, this is set to the regular bonus. It is good also as what controls to a bonus. In other words, the big bonus can be provided by repeating the regular bonus until the number of paid-out medals reaches a specified number.

  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 be aligned.

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

  In the above embodiment, the variable display device 2 includes the three reels 3L, 3C, and 3R in which a plurality of symbols are arranged in a predetermined order on the outer 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. 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.
