Abstract

<P>PROBLEM TO BE SOLVED: To provide a game property based on a variable display device for performances different from a variable display device to be used for judging winning and to derive a display result at the variable display device for the performances without making a player have the feeling of incompatibility. <P>SOLUTION: Virtual reels are displayed at a liquid crystal display device which can be more easily viewed than the variable display device to be used for judging the winning. Stoppage is performed in the range of pulling in four frames from a pattern at the point of time of operating a stop button corresponding to not only the reel of the variable display device but also the virtual reel. When a big bonus winning flag is set, the array of the patterns of the respective virtual reels are surely changed to the array in which "7" is arranged at an interval of five frames or less. When the display form of a big bonus is derived at the variable display device corresponding to the operation timing of the stop button, the display form (7-7-7) of the big bonus is surely derived on the virtual reels within the range of pulling in four frames. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a slot machine, and more particularly to a slot machine having an effect variable display device in addition to a variable display device used for winning determination.

  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 when all the reels stop rotating. When a combination of symbols stopped on the active line is in a predetermined display mode, a winning is generated. Each reel constituting the variable display device starts rotating when the player operates the start lever, and stops when the player operates a stop button provided corresponding to each reel.

  Since the rotation of each reel is stopped by the operation of the stop button in this way, if the rotation can be stopped regardless of the operation timing, the player's technical intervention of the stop button operation is It becomes meaningless. For this reason, the rotation of each reel is stopped within the range of the maximum stop delay time determined in advance from the operation of the stop button. Accordingly, the operation timing of the stop button is a very important factor whether or not a winning can be generated.

  Therefore, it is preferable to rotate the reels constituting the variable display device in accordance with a certain standard so that the player does not feel distrust. For this reason, a high effect cannot be achieved only by rotating / stopping the reels constituting the variable display device designed according to a certain standard. In view of this, there has been proposed a slot machine that is provided with a variable display device for performance separate from the variable display device, and realizes game play with this variable display device for performance. This slot machine allows the game to proceed even if the player looks only at the production variable display device without looking at the original variable display device (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 2002-793 (paragraphs 0027 and 0070, FIG. 1)

  In the slot machine of Patent Document 1, the original variable display device determines whether or not there is a prize, so that it is required to rotate / stop the reel according to certain rules from the viewpoint of ensuring the fairness of the game. The On the other hand, since the variable display device for production does not determine the presence or absence of winning, even if the design is changed without being bound by the rules, it may cause a problem from the viewpoint of game fairness. Absent.

  However, if the player advances the game mainly using the production variable display device, it is not necessary for the player to feel a sense of incongruity if the variation of the design in the production variable display device is performed according to a certain standard. On the other hand, in order to take advantage of the provision of the variable display device for production separately from the original variable display device, the variation in the design of the variable display device for production is the variation of the design of the reel constituting the variable display device. There is also a request to make it different.

  By the way, as a combination in the slot machine, there are a small combination with payout of medals, a replay combination with replaying, and a bonus combination with a transition to a gaming state advantageous to the player. There are many small roles and replays that will not be missed regardless of the stop button operation timing if winning in the internal lottery, but the bonus role is generally a missed role that wins depending on the stop button operation timing. It has become. This is intended to require the player's technical intervention to win a bonus.

  Here, if the display mode corresponding to the display result of the variable display device is derived in the variable display device for production, for example, when the display result of the bonus combination is derived in the variable display device, the variable display for production The device must also derive the bonus combination display result. On the other hand, in the case where the design is changed in the production variable display device while satisfying the request for making the design different from the change in the design of the reels constituting the variable display device, many bonus designs are produced in the production variable display device. Otherwise, it may be necessary to derive the display mode of the bonus combination by increasing the number of drawn frames, which may make the player feel uncomfortable about the stop of the symbol. On the other hand, if arrangement is made in advance so that bonus symbols can be always pulled in, the arrangement will be such that it is not often used in reels of variable display devices, which may cause the player to feel uncomfortable.

  The present invention realizes the gameability mainly based on a variable display device for production different from the variable display device used for winning determination, and displays the display result on the variable display device for production without making the player feel uncomfortable. It is an object to provide a slot machine that can be derived.

In order to achieve the above object, a slot machine according to the first aspect of the present invention includes:
By setting a predetermined number of bets for one game, the game can be started, and the display result is displayed on a variable display device (variable display device 2) that variably displays a plurality of types of identification information each of which can be identified. In a slot machine in which one game is completed by being derived and winning can be generated according to the display result derived to the variable display device,
An effect variable display device (liquid crystal display 4) that is provided separately from the variable display device, is provided more easily than the variable display device, and displays a plurality of types of effect identification information that can be distinguished from each other. (Virtual reel))
Allowed to derive a plurality of types of winning display results including special display results (big bonus (1), big bonus (2)) with a transition of the gaming state before the display results of the variable display device are derived Pre-determining means (steps S102 to S111) for determining whether to do by lottery,
Stop operation means (stop buttons 12L, 12C, 12R) for instructing to stop the variable display of the identification information on the variable display device by the player's operation;
Stop operation detection means (stop switches 42L, 42C, 42R) for detecting the operation of the stop operation means;
When the stop operation detecting unit detects an operation of the stop operation unit, the variable display of the identification information is stopped according to the operation procedure of the stop operation unit and the determination result of the prior determination unit, and the variable Derivation control means (Steps S305 → S307, S310 → S312 and S315 → S317) for deriving the display result of the display device;
When the stop operation detecting means detects the operation of the stop operation means, the effect identification information is displayed in a variable manner within a range of the maximum effect delay time (190 milliseconds) determined in advance from the detection of the operation. Production derivation control means (steps S611 to S613) for causing the production variable display device to derive the production display result corresponding to the display result of the variable display device,
When the special display result is derived as the display result of the variable display device, special game state control means for shifting the game state from the next game to a special game state (big bonus) different from the normal game state (step S402) , S404)
The derivation control unit causes the special display result to be derived when the stop operation unit is operated in a predetermined procedure when the prior determination unit determines to permit the derivation of the special display result. In addition, when operated in a procedure other than the predetermined procedure, a display result other than the special display result is derived (FIGS. 2 and 3),
The production variable display device has one or more production variable display areas for variably displaying a plurality of types of production identification information in accordance with a predetermined normal arrangement (FIG. 10).
The normal arrangement includes special effect identification information (7) constituting the special display result (big bonus display mode) corresponding to the special display result, and includes one special display identification information and other The maximum variation that is the maximum range in which the number of other identification information for presentation existing between the special identification information for presentation can be variably displayed during the maximum delay time for presentation even after the stop operation means is operated. Including locations that are larger than the number of production identification information included in the range (four frames),
An effect identification that is variably displayed in the effect variable display area before the stop operation means becomes operable when it is determined by the prior determination means that the derivation of the special display result is allowed. The number of other production identification information existing between one production special identification information and another production special identification information is greater than the number of production identification information included in the maximum variation range. Special time arrangement changing means (steps S605 → S607) for changing to a special time arrangement (FIG. 11) not including the enlarged portion and variably displaying a plurality of types of effect identification information according to the special time arrangement,
The effect derivation control means, when the special display result is derived to the variable display device, causes the effect variable display device to derive the effect special display result according to the special time arrangement changing means. Features.

  In the slot machine according to the first aspect, when it is determined by the predetermining means that the derivation of the special display result is permitted, the arrangement of the production identification information in the production variable display area is changed from the normal arrangement to the special time. Changed to an array. In the normal arrangement, the number of other effect identification information existing between one effect special identification information and the other special effect identification information is larger than the number of effect identification information included in the maximum variation range. However, the special time arrangement does not include such a part. Therefore, when it is determined that the derivation of the special display result is permitted, the special display result is derived to the variable display device by operating the stop operation means in a predetermined procedure. If the information is variably displayed, the effect special identification information can be stopped at an arbitrary position, and the effect special display result can always be derived within the range of the effect maximum delay time. Therefore, the player does not feel uncomfortable in causing the effect variable display device to derive the effect special display result as the variable display device derives the special display result.

  Further, when it is not determined that the derivation of the special display result is permitted, the effect identification information is variably displayed according to the normal time arrangement instead of the special time arrangement. In the special time arrangement, the number of other effect identification information existing between one effect special identification information and another special effect identification information is larger than the number of effect identification information included in the maximum variation range. Therefore, the number of special identification information for performance that must be arranged at least is increased. On the other hand, since it is not necessary to include such a part in the normal time arrangement, the number of special identification information for performance is not restricted as in the special time arrangement. For this reason, even a player who is accustomed to the arrangement of identification information in a general variable display device is less likely to feel discomfort in the arrangement of identification information for presentation.

  The production variable display area may circulate and display a plurality of types of production identification information, or may include only one production special identification information. In this case, the other effect identification information existing between the one effect special identification information and the other effect identification information is circulated from only one effect special identification information. It means other identification information for presentation included while reaching the special identification information for presentation. When the production variable display device includes two or more production variable display areas, the production variable display area in which the production identification information is variably displayed according to the normal arrangement is only a part of the production variable display area. It may be.

  The timing of changing the arrangement of the identification information for presentation may be the timing before the stop operation means can be operated and after the variable display is started on the presentation variable display device. Further, it is preferable to sequentially change the effect identification information that is not displayed in the display area of the effect variable display device. By replacing the production identification information by such a method, it is possible to avoid making the player feel uncomfortable when replacing the production identification information.

In the slot machine according to the first aspect,
The normal time arrangement and the special time arrangement further exist between one production non-special identification information and another production non-special identification information constituting the production non-special display result corresponding to the non-special display result. It is possible not to include a part where the number of other identification information for presentation is larger than the number of identification information for presentation included in the maximum variation range (FIG. 11).

  Here, in the normal time arrangement and the special time arrangement, the maximum variation range includes the number of other production identification information existing between one production non-specific identification information and other special production non-identification information. Since the portion larger than the number of identification information for effects is not included, the non-special identification information for effects can also be stopped at an arbitrary position. For this reason, when the non-special display result is derived to the variable display device, the effect non-special display result can be always derived within the range of the effect maximum delay time, and the player does not feel uncomfortable. In particular, in the special time arrangement, a game can be used to cause the variable display device for effects to derive the display result for performance corresponding to the winning display result of either the special display result or the non-special display result derived from the variable display device. It is not necessary to make the person feel uncomfortable.

The slot machine according to the first aspect is
When it is determined by the pre-determining means that the derivation of the special display result is permitted, it further includes special determination carry-over means (step S514) for carrying over the determination until the special display result is derived,
The pre-determining means also includes a non-special display result other than the special display result as the winning display result even when the decision to allow the derivation of the special display result is carried forward by the special determination carry-over means ( It may be possible to determine that the derivation of (bell) is permitted. here,
When the variable display device for effects has two or more variable display areas for effects,
The special time arrangement is another production identification existing between one production non-special identification information and another production non-special identification information constituting a production non-special display result corresponding to the non-special display result. It does not include the part where the number of information is larger than the number of effect identification information included in the maximum variation range, and finally stops the variation display of the effect identification information among the two or more effect variable display areas. In the variable display area for effects other than the variable display area for final effects, both the display form constituting a part of the special display result for effect and the display form constituting a part of the non-special display result for effect are derived. It can be an arrangement that can be made to be. In this case,
The effect derivation control means, when the decision to allow the derivation of the special display result is carried over, and when it is determined to allow the derivation of the small part display result, according to the special time arrangement, Deriving both a display form constituting a part of the special display result for the effect and a display form constituting a part of the non-special display result for the effect in the variable display area for the effect other than the variable display area for the final effect Can do.

  Here, in the variable display area for effects other than the final effect variable display area, a display mode that constitutes a part of the special display result for effect and a display aspect that constitutes a part of the non-special display result for effect are derived. Yes. The display mode of the production variable display device until the variable display in the final production variable display area is stopped is a display mode in which the production special display result and the production non-special display result can be derived. For this reason, when the display result is finally derived to the variable display device, it is possible to derive both the special display result for effect and the non-special display result for effect according to the display result.

The slot machine according to the first aspect is
Non-special time arrangement change that changes the arrangement of the identification information for presentation to the special time arrangement at a predetermined ratio even when it is not decided by the pre-determining means that the derivation of the special display result is allowed Means (FIG. 11, step S605) may be further provided.

  In this case, even when it is not determined that the derivation of the special display result is permitted, the arrangement of the effect identification information is changed to the special time arrangement at a predetermined rate. Therefore, even if it is not actually decided to allow the derivation of the special display result, if the arrangement of the identification information for presentation is changed to the special time arrangement, the derivation of the special display result is permitted. It is possible to give a player a sense of expectation and improve the fun of the game.

In order to achieve the above object, a slot machine according to the second aspect of the present invention provides:
By setting a predetermined number of bets for one game, the game can be started, and the display result is displayed on a variable display device (variable display device 2) that variably displays a plurality of types of identification information each of which can be identified. In a slot machine in which one game is completed by being derived and winning can be generated according to the display result derived to the variable display device,
An effect variable display device (liquid crystal display 4) that is provided separately from the variable display device, is provided more easily than the variable display device, and displays a plurality of types of effect identification information that can be distinguished from each other. (Virtual reel))
Allowed to derive a plurality of types of winning display results including special display results (big bonus (1), big bonus (2)) with a transition of the gaming state before the display results of the variable display device are derived Pre-determining means (steps S102 to S111) for determining whether to do by lottery,
Stop operation means (stop buttons 12L, 12C, 12R) for instructing to stop the variable display of the identification information on the variable display device by the player's operation;
Stop operation detection means (stop switches 42L, 42C, 42R) for detecting the operation of the stop operation means;
When the stop operation detecting unit detects an operation of the stop operation unit, the variable display of the identification information is stopped according to the operation procedure of the stop operation unit and the determination result of the prior determination unit, and the variable Derivation control means (Steps S305 → S307, S310 → S312 and S315 → S317) for deriving the display result of the display device;
When the stop operation detecting means detects the operation of the stop operation means, the effect identification information is displayed in a variable manner within a range of the maximum effect delay time (190 milliseconds) determined in advance from the detection of the operation. Production derivation control means (steps S611 to S613) for causing the production variable display device to derive the production display result corresponding to the display result of the variable display device,
When the special display result is derived as the display result of the variable display device, special game state control means for shifting the game state from the next game to a special game state (big bonus) different from the normal game state (step S402) , S404)
The derivation control unit causes the special display result to be derived when the stop operation unit is operated in a predetermined procedure when the prior determination unit determines to permit the derivation of the special display result. In addition, when operated in a procedure other than the predetermined procedure, a display result other than the special display result is derived (FIGS. 2 and 3),
The effect variable display device variably displays a plurality of types of effect identification information in accordance with a predetermined normal arrangement (FIG. 10), and simultaneously displays a plurality of effect identification information so as to be visible (displayed in three stages). One or more variable display areas for production,
The normal arrangement includes special effect identification information (7) constituting the special display result (big bonus display mode) corresponding to the special display result, and includes one special display identification information and other The maximum variation that is the maximum range in which the number of other identification information for presentation existing between the special identification information for presentation can be variably displayed during the maximum delay time for presentation even after the stop operation means is operated. Including locations that are larger than the number of production identification information included in the range (four frames),
Visible number reducing means for reducing the number of effect identification information that can be visually recognized simultaneously in the effect variable display area when it is determined by the prior determination means that the derivation of the special display result is allowed. In addition,
When the special display result is derived to the variable display device, the effect derivation control means displays the effect identification information displayed at least when the stop operation means is operated and the maximum variation. When the effect identification information included in the range does not include the effect special identification information, the effect identification information included in the maximum variation range is replaced with the effect special identification information. Replacement derivation control means for deriving the special display result for presentation by deriving and displaying the identification information so as to be visible is provided.

  In the slot machine according to the second aspect, when it is determined by the predetermining means that the derivation of the special display result is permitted, the number of identification information visible in the effect variable display area is reduced. When the special identification information for presentation is not included in the identification information for presentation displayed so as to be visible when the stop operation means is operated and the identification information for presentation included in the maximum variation range The effect identification information included in the maximum variation range is replaced with effect special identification information. For this reason, when the special display result is derived to the variable display device, the special identification information for production can be stopped as visible identification information for production, and the special production for production is always within the range of the maximum delay time for production. The display result can be derived. On the other hand, when replacement to the special identification information for production is performed, the number of identification information for production that can be visually recognized simultaneously in the variable display area for production is reduced, and the replacement is noticed depending on the arrangement order of the visual identification information for presentation. So that the player does not feel uncomfortable.

  Further, in the effect variable display area, the effect identification information is variably displayed according to the normal time arrangement, but the normal time arrangement exists between one special effect identification information and another special effect identification information. It may include a place where the number of other identification information for presentation is larger than the number of identification information for presentation included in the maximum variation range. Therefore, the number of special identification information for performance included in the normal arrangement can be small. For this reason, even a player who is accustomed to the arrangement of identification information in a general variable display device is less likely to feel discomfort in the arrangement of identification information for presentation.

  The production variable display area may circulate and display a plurality of types of production identification information, or may include only one production special identification information. In this case, the other effect identification information existing between the one effect special identification information and the other effect identification information is circulated from only one effect special identification information. It means other identification information for presentation included while reaching the special identification information for presentation. When the production variable display device includes two or more production variable display areas, the production variable display area in which the production identification information is variably displayed according to the normal arrangement is only a part of the production variable display area. It may be.

  Further, the reduction in the number of identification information that can be simultaneously viewed by the visible number reduction means is not limited to that in which the number of identification information that can be completely viewed is reduced, but a plurality of display information that is displayed in the production variable display area. Among the visual identification information, the visual recognition state of a part of the production identification information may be made lower than the visual recognition state of other partial production identification information. Here, the visible number reducing means may reduce the number of identification information visible simultaneously to one.

  Further, the replacement derivation control means, when the special display result is derived to the variable display device, in order to cause the special display result for the effect to be derived when the stop operation means is operated. The presentation special identification information can be replaced on the condition that the special identification information for presentation does not exist between the position where the identification information should be derived and the maximum variation range. When the special display result is derived on the variable display device, the special identification for presentation is performed between the maximum variation range from the position where the special identification information for presentation is to be derived in order to derive the special display result for presentation. When the information can exist, the special identification information for presentation can be derived as the identification information for presentation that can be visually recognized even after the reduction by the visible number reducing means, without replacing with the special identification information for presentation. . Of course, the effect special identification information may be replaced and the effect special identification information may be derived as the effect identification information that is visible even after being reduced by the viewable number reducing means.

In the slot machine according to the second aspect,
When it is determined by the pre-determining means that the derivation of the special display result is permitted, it further includes special determination carry-over means (step S514) for carrying over the determination until the special display result is derived,
The pre-determining means also includes a non-special display result other than the special display result as the winning display result even when the decision to allow the derivation of the special display result is carried forward by the special determination carry-over means ( It may be possible to determine that the derivation of (bell) is permitted. here,
When the production variable display device has two or more production variable display areas for simultaneously displaying a plurality of production identification information in a visually recognizable manner,
When the decision to allow derivation of the special display result is carried over and the decision to permit derivation of the small part display result is made, the derivation control means for production is the variable for the two or more productions In the display variable display area other than the final effect variable display area that stops the variable display of the effect identification information last in the display area, the effect non-display corresponding to the effect special display result and the non-special display result is displayed. The pre-final derivation control means for deriving and displaying the shared identification information for effects constituting both of the special display results can be provided.

  Thus, until the variable display in the final effect variable display area is stopped, the display mode of the effect variable display device is also displayed in accordance with the display result finally derived to the variable display device. Non-special display results can also be derived.

  Here, the pre-final derivation control means includes the effect identification information displayed so as to be visible at least when the stop operation means is operated in the effect variable display region other than the final effect variable display region, and When the production identification information included in the maximum variation range does not include the production shared identification information, the production identification information included in the maximum variation range is replaced with the production common identification information. The shared shared identification information can be derived and displayed so as to be visible. Note that the production shared identification information may not be included in the normal arrangement.

Further, the normal-time arrangement further includes other non-special identification information for presentation and other non-special identification information for presentation that constitutes the non-special display result for presentation corresponding to the non-special display result. Even if it does not include a part where the number of pieces of identification information for presentation is larger than the number of pieces of identification information for presentation included in the maximum variation range, it may include the part. In the latter case,
The replacement derivation control means is displayed so as to be visible at least when the stop operation means is operated in the final effect variable display area when the non-special display result is derived to the variable display device. When the production identification information and the production identification information included in the maximum variation range do not include the production non-special identification information, the production identification information included in the maximum variation range is converted to the production non-production information. The special identification information for presentation can be derived and displayed so as to be visible in place of the special identification information.

The slot machine according to the first and second aspects is as follows.
The visible number reducing means is for a production that is visible at the same time in the production variable display area at a predetermined rate even when it is not decided by the pre-decision means to derive the special display result. The number of identification information can be reduced.

  In this case, even when it is not determined that the derivation of the special display result is permitted, the number of effect identification information that can be simultaneously viewed in the effect variable display area is reduced at a predetermined rate. For this reason, even if it is not determined that the derivation of the special display result is actually permitted, the derivation of the special display result is permitted if the number of presentation identification information that can be viewed at the same time is reduced. It is possible to give a player a sense of expectation and improve the fun of the game.

In order to achieve the above object, a slot machine according to the third aspect of the present invention provides:
By setting a predetermined number of bets for one game, the game can be started, and the display result is displayed on a variable display device (variable display device 2) that variably displays a plurality of types of identification information each of which can be identified. In a slot machine in which one game is completed by being derived and winning can be generated according to the display result derived to the variable display device,
An effect variable display device (liquid crystal display 4) that is provided separately from the variable display device, is provided more easily than the variable display device, and displays a plurality of types of effect identification information that can be distinguished from each other. (Virtual reel))
Allowed to derive a plurality of types of winning display results including special display results (big bonus (1), big bonus (2)) with a transition of the gaming state before the display results of the variable display device are derived Pre-determining means (steps S102 to S111) for determining whether to do by lottery,
Stop operation means (stop buttons 12L, 12C, 12R) for instructing to stop the variable display of the identification information on the variable display device by the player's operation;
Stop operation detection means (stop switches 42L, 42C, 42R) for detecting the operation of the stop operation means;
When the stop operation detecting unit detects an operation of the stop operation unit, the variable display of the identification information is stopped according to the operation procedure of the stop operation unit and the determination result of the prior determination unit, and the variable Derivation control means (Steps S305 → S307, S310 → S312 and S315 → S317) for deriving the display result of the display device;
When the stop operation detecting means detects the operation of the stop operation means, the effect identification information is displayed in a variable manner within a range of the maximum effect delay time (190 milliseconds) determined in advance from the detection of the operation. Production derivation control means (steps S611 to S613) for causing the production variable display device to derive the production display result corresponding to the display result of the variable display device,
When the special display result is derived as the display result of the variable display device, special game state control means for shifting the game state from the next game to a special game state (big bonus) different from the normal game state (step S402) , S404)
The derivation control unit causes the special display result to be derived when the stop operation unit is operated in a predetermined procedure when the prior determination unit determines to permit the derivation of the special display result. In addition, when operated in a procedure other than the predetermined procedure, a display result other than the special display result is derived (FIGS. 2 and 3),
The production variable display device has one or more production variable display areas for variably displaying a plurality of types of production identification information in accordance with a predetermined normal arrangement (FIG. 10).
The normal arrangement includes special effect identification information (7) constituting the special display result (big bonus display mode) corresponding to the special display result, and includes one special display identification information and other The maximum variation that is the maximum range in which the number of other identification information for presentation existing between the special identification information for presentation can be variably displayed during the maximum delay time for presentation even after the stop operation means is operated. Including locations that are larger than the number of production identification information included in the range (four frames),
The effect derivation control means is provided between the maximum variation range from a position where the effect special identification information should be derived in order to derive the effect special display result at least when the stop operation means is operated. When there is no special identification information for production, the special display result for production is obtained by deriving the special identification information for production by replacing the production identification information included in the maximum variation range with the special identification information for production. A replacement derivation control means for deriving is provided.

  In the slot machine according to the third aspect, the effect identification information included in the effect identification information that is displayed so as to be visible when the stop operation means is operated and the effect identification information included in the maximum variation range are displayed. When the special identification information is not included, the effect identification information included in the maximum variation range is replaced with the effect special identification information. For this reason, when the special display result is derived to the variable display device, the special identification information for production can be stopped as visible identification information for production, and the special production for production is always within the range of the maximum delay time for production. The display result can be derived.

  Further, in the effect variable display area, the effect identification information is variably displayed according to the normal time arrangement, but the normal time arrangement exists between one special effect identification information and another special effect identification information. It may include a place where the number of other identification information for presentation is larger than the number of identification information for presentation included in the maximum variation range. Therefore, the number of special identification information for performance included in the normal arrangement can be small. For this reason, even a player who is accustomed to the arrangement of identification information in a general variable display device is less likely to feel discomfort in the arrangement of identification information for presentation.

  The production variable display area may circulate and display a plurality of types of production identification information, or may include only one production special identification information. In this case, the other effect identification information existing between the one effect special identification information and the other effect identification information is circulated from only one effect special identification information. It means the other identification information for presentation included while arriving at the special identification information for presentation. When the production variable display device includes two or more production variable display areas, the production variable display area in which the production identification information is variably displayed according to the normal arrangement is only a part of the production variable display area. It may be.

  Here, the replacement derivation control means is effect identification information that is not displayed on the effect variable display device when an operation of the stop operation means is detected in the arrangement of the effect identification information. It is preferable to replace the effect identification information that can be derived within the range of the maximum effect delay time from the detection of the operation with the special effect identification information. In this case, if you look at the relationship between the identification information for presentation and the arrangement of the identification information for presentation, you can see that the arrangement of the identification information for presentation has been changed. Since it is not known that the arrangement of the identification information has been changed, it is possible to minimize the uncomfortable feeling that the player feels as a result of replacement with the special identification information for performance.

The slot machine according to the first to third aspects is as follows.
In the special gaming state, when a special special display result (JACIN) different from the special display result is derived as the winning display result to the variable display device, the gaming state is specially designated from the next game in the special gaming state. Special special game state control means (step S408) for controlling to a special game state (regular bonus) may be further provided. In this case,
The pre-determining means includes
When the normal game state is controlled, it is determined whether or not the replay display result (replay) with the replay grant and the derivation of the special display result are allowed, and the value with a predetermined probability is determined. Is determined to permit the derivation of the small-combination display result (bell, cherry) accompanied by (Fig. 5 (a)),
When the special gaming state is not controlled to the special special gaming state (small bonus game in a big bonus), it is determined whether or not at least derivation of the small bonus display result and the special special display result is allowed (FIG. 5 (a)),
When the special gaming state is controlled to the special special gaming state (regular bonus in the big bonus), it is determined that the derivation of the small role display result is allowed with a probability equal to or higher than the predetermined probability; (FIGS. 7A and 7C).

  Here, when the game is controlled in the normal game state, in the special game state, it is not controlled in the special special game state, and when it is controlled in the special special game state, the pre-determining means displays the small role display It will be decided whether to permit the derivation of the result. The small combination display result is accompanied by the addition of a valuable value due to the occurrence of a prize, and is a basic prize display result in a game of a slot machine. Thus, by determining the small combination display result, which is the basic winning display result, as the type of winning in any gaming state, the game becomes easy for the player to understand. In addition, the probability that it is decided to allow the derivation of the small role display result is more than that when it is controlled to the normal gaming state when it is controlled to the special special gaming state. By being controlled, it is possible to increase the player's expectation for the derivation of the small role display result.

  In this case, the pre-determining means determines whether to permit the derivation of only the special special display result and the small role display result when the special game state is not controlled to the special special game state. It may be determined (FIG. 5A).

  When the re-game display result is derived, valuable value is not consumed for setting the number of bets in the next game, but it does not pay out valuable value, so it does not affect the end of the special gaming state. . In other words, even if the re-game display result is derived when the special game state is not controlled to the special special game state, the number of games in the special game state is unnecessarily increased. Since the means does not determine that the derivation of the re-game display result is permitted, the special game state is not prolonged unnecessarily, and the game can be advanced efficiently.

  The special special display result is preferably composed of a combination of identification information (bell-cherry-cherry) different from the combination of identification information constituting the winning display result in the normal gaming state (see FIG. 5 (a)).

  The special special display result cannot be derived as the winning display result in the normal gaming state, but is not the one that wins by the same combination of identification information as the winning display result in the normal gaming state. Absent. For this reason, the role for each combination of identification information becomes clear, and the game is easy to understand for the player.

In this case,
The derivation control means is a specific small combination display result with the highest probability that it is determined that the derivation is allowed by the pre-determining means among the small combination display results in the game controlled to the special special gaming state. When it is determined that the derivation of (bell) is permitted, it is preferable that the specific small combination display result is derived regardless of the operation procedure of the stop operation means (FIGS. 2 and 3). .

  In this case, the specified small combination display result determined to be permitted to be derived in the special special gaming state can be always derived regardless of the operation procedure of the stop operation means, so that no oversight occurs. For this reason, in the special special game state, it is less necessary for the player to make a so-called push and the game can be easily advanced.

  In addition, when the small display display result is derived for the first time after being controlled to the special gaming state, when the special display result for production is derived by the variable display device for production, Whether or not the special display result for performance should be derived at this point can be determined depending on whether or not the derivation is permitted. For this reason, it is not necessary to control the display result derived to the effect variable display device according to the operation procedure of the stop operation means, and the processing load is reduced.

The slot machine according to the first to third aspects is as follows.
Numerical data input means for inputting numerical data to be updated within a predetermined range to a predetermined determination area (general-purpose register 111GR) as determination numerical data (random number for internal lottery) at a predetermined timing for each game ( Step S202) can further be provided,
The prior determination means may determine whether or not to allow the plurality of types of winning display results to be derived in accordance with the value of the determination numerical data input to the determination area. (Steps S106, S107). Here, the slot machine is
Any one of a plurality of allowable stages (setting value 1 to setting value 6 (FIG. 5B)) having different probabilities for determining that the pre-determining means allows the winning display result to be derived. A permissible step setting means (setting switch 91) for selecting and setting the permissible step;
Judgment that the predetermination means decides to permit the derivation for the numeric data for judgment input to the judgment area for any one or more types of winning display results (JACIN, cherry, replay) Determination value data (the number of determination values) indicating the number of values is stored in common for the plurality of types of allowable stages, and a winning display result of a type in which determination value data is not stored in common for the allowable levels ( For the regular bonus, the big bonus (1), the big bonus (2), and the bell), it is determined that the predetermination means permits the derivation with respect to the numerical data for determination input in the determination area. Judgment value data storage means (FIG. 5 (b), FIG. 6) for separately storing judgment value data indicating the number of judgment values according to the type of the allowable stage is further provided. Can. In this case,
The pre-determining means is the determination numerical data input to the determination area in accordance with the determination value data stored in the determination value data storage means corresponding to the allowable stage set by the allowable stage setting means. Is provided with determination means (step S109) for determining whether or not derivation is permitted for each type of the winning display result, and the type determined to indicate that derivation is permitted by the determination means It is possible to determine that the derivation of the winning display result is permitted (step S110).

  Here, the determination value data storage means stores the determination value data in common for a plurality of types of allowable stages for any one or more types of winning display results, and according to the types of allowable levels for other types of winning display results. Judgment value data is stored individually. Thus, for one or more types of winning display results in which determination value data is stored in common for a plurality of types of allowable stages, the storage capacity required for storing the determination value data may be small.

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

In this case,
The predetermination means sequentially inputs the judgment value data stored in the judgment value data storage means corresponding to the allowable stage set by the allowable stage setting means to the determination area for each type of winning display result. An addition means (step S108) for adding to the determined numerical data for determination may be further provided. here,
The determination means determines whether or not the addition result of the addition means exceeds the predetermined range (step S109), and performs addition when it is determined that the predetermined range is exceeded by the result of the determination It can be determined that it indicates that the derivation of the winning display result of the type corresponding to the determination value data is permitted (step S110).

  In this case, after the determination value data is extracted from the determination value data storage means for each type of the winning display result, the determination numerical data is added to the determination value data, thereby permitting the derivation of the winning display result of that type as it is. It can be determined whether or not. That is, the processing efficiency is high because there is no need to register the determination value for each winning display result in the allowable determination value registration means based on the determination value data.

The pre-determining means displays a winning display of the judgment value data stored in the judgment value data storage means corresponding to the type of the permissible stage set by the permissible stage setting means, instead of the adding means. Subtracting means for subtracting from the numerical data for determination input to the determination area sequentially for each result type may be provided. in this case,
The determination unit determines whether or not the subtraction result of the subtraction unit is smaller than the predetermined range, and performs subtraction when it is determined that the subtraction result is smaller than the predetermined range based on the determination result. It can be determined that it indicates that the derivation of the winning display result of the type corresponding to the determination value data is permitted.

Also here
The determination value data storage means includes different number determination value data (FIG. 6: big bonus (1), big bonus (2) indicating the number of different determination values as the determination value data individually stored according to the type of the permissible stage. ), Bell) and the same number determination value data (FIG. 6: regular bonus) indicating the same number of determination values as the determination value data individually stored according to the type of the permissible stage, and the type of the winning display result It is good also as what memorizes according to.

  Judgment value data determines the probability that the pre-determining means decides to allow the derivation of each winning display result according to the allowable stage. In general, the simulation is performed while adjusting to (the initial judgment value data may be different or may be the same). Appropriate judgment value data obtained as a result of simulation is applied to a model for mass production.

  Here, even if the determination value data becomes the same regardless of the allowable stage as a result of performing the simulation while changing the determination value data according to the allowable stage, such a type of winning display result is not changed. The judgment value data may be stored individually according to the type of the allowable stage. In addition, when the judgment value data is initially stored as the same number of judgment value data indicating the same judgment value individually according to the type of the permissible stage, the judgment value data that is initially registered according to the simulation result remains unchanged. If so, it can be stored in the determination value data storage means as it is as the same number of determination value data. When there is a problem with the judgment value data initially registered as a result of the simulation, the judgment value data can be changed in accordance with the allowable stage and stored in the judgment value data storage means as different number judgment value data. For this reason, since the storage mode of the judgment value 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.

The slot machine according to the first to third aspects is as follows.
Numerical data updated within a predetermined range is determined in advance as numerical data for determination (random number for internal lottery) at a timing corresponding to a predetermined operation (operation of the start lever 11) by the player for each game. Numerical data input means (step S202) for inputting into the area (general-purpose register 111GR) can be further provided.
The prior determination means may determine whether or not to allow the plurality of types of winning display results to be derived in accordance with the value of the determination numerical data input to the determination area. (Steps S106, S107). Here, 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, the n-bit array data signal output from the counter circuit is latched, and the bit order of the latched n-bit array data signal is changed.

The numerical data input means replaces the specific bit data of the n-bit numerical data input to the specific area with the other bits of the numerical data, and performs the replacement n Bit replacement numerical data can be input to the determination area as the determination numerical data (steps S203 to S205).

  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.

The slot machine according to the first to third aspects is as follows.
Numerical data updated within a predetermined range is determined in advance as numerical data for determination (random number for internal lottery) at a timing corresponding to a predetermined operation (operation of the start lever 11) by the player for each game. Numerical data input means (step S202) for inputting into the area (general-purpose register 111GR) can be further provided.
The prior determination means may determine whether or not to allow the plurality of types of winning display results to be derived in accordance with the value of the determination numerical data input to the determination area. (Steps S106, S107). Here, 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, the n-bit array data signal output from the counter circuit is latched, and the bit order of the latched n-bit array data signal is changed.

The numerical data input means may input operation result numerical data consisting of upper k bits and lower j bits after the operation by the operation means to the determination area as the determination numerical data (see FIG. 19).

  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.

The slot machine according to the first to third aspects is as follows.
Numerical data updated within a predetermined range is determined in advance as numerical data for determination (random number for internal lottery) at a timing corresponding to a predetermined operation (operation of the start lever 11) by the player for each game.

The prior determination means may determine whether or not to allow the plurality of types of winning display results to be derived in accordance with the value of the determination numerical data input to the determination area. (Steps S106, S107). Here, the slot machine is

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, the n-bit array data signal output from the counter circuit is latched, and the bit order of the latched n-bit array data signal is changed. A latch circuit (sampling circuit 116) that outputs without any error,
Input means (FIG. 20) for inputting an n-bit array data signal output from the latch circuit to the predetermined specific area (general-purpose register 111GR) as n-bit first numerical data without changing the bit array order. When,
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;

  Here, for 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, the second numerical data extracted from the numerical value updating means by the numerical value extracting means is used. Calculation result numerical data obtained by performing a predetermined calculation using the data is input as determination numerical data. The numerical value indicated by the arithmetic result numerical data is not calculated by using the second numerical data as it is for the first numerical data, but by performing an operation on the upper k bits of the first numerical data. Variations increase. The variation is further increased by performing an operation on the lower j bits.

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

The pre-determining means derives the winning display result by determining whether or not the determination numerical data input to the determination area indicates that derivation is allowed for each type of the winning display result. It can be decided whether or not to allow this.

In addition, as a variation of the above,
When a predetermined extraction condition resulting from the player's operation is satisfied, the order of bit arrangement is not changed for each of the upper n bits and the lower n bits of the data signal output from the counter circuit, and The upper n bits of the data signal output from the counter circuit are set to lower numerical data which is the lower n bits of the 2n-bit numerical data, and the lower n bits of the data signal output from the counter circuit are set to the 2n Numeric data fetching means (FIGS. 24 (a) to (d)) for fetching the 2n-bit numeric data as upper numeric data which is the upper n bits of the bit numeric data;

Moreover, as a further modification example of the above,
When a predetermined extraction condition resulting from the player's operation is satisfied, the bit order is made different for each of the upper n bits and the lower n bits of the data signal output by the counter circuit, and The upper n bits of the data signal output from the counter circuit are upper numerical data that is the upper n bits of the 2n-bit numerical data, and the lower n bits of the data signal output from the counter circuit are Numeric data fetching means (FIGS. 22 (a) to (d)) for fetching the 2n-bit numeric data as lower numeric data which is the lower n bits of the 2n-bit numeric data;
The upper numerical data and the lower numerical data captured by the numerical data capturing means are replaced with each other as the specific lower numerical data and the specific upper numerical data, respectively, and the specific upper area and the specific provided in the storage means provided in the game control means Data replacement means (FIG. 22 (e)) for storing in the lower area;
Determining that the game control means includes numerical data obtained by performing a predetermined operation on the numerical data stored in the specific upper area and setting the numerical data obtained as a result of the predetermined operation as upper n bits. Numerical data input means (FIG. 21 (e), (f), (g), (h), (j)) for inputting into the area may be further provided,
The numerical data input means performs an exclusive OR operation on the numerical data stored in the specific lower area with respect to the numerical data stored in the specific upper area as the predetermined operation. Including calculation means (FIG. 21 (h)),
The pre-determining means derives the winning display result by determining whether or not the determination numerical data input to the determination area indicates that derivation is allowed for each type of the winning display result. It can be decided whether or not to allow this.

Moreover, as a further modification example of the above,
When a predetermined extraction condition resulting from the player's operation is satisfied, the order of bit arrangement is not changed for each of the upper n bits and the lower n bits of the data signal output from the counter circuit, and The upper n bits of the data signal output from the counter circuit are set to upper numerical data which is the upper n bits of the 2n-bit numerical data, and the lower n bits of the data signal output from the counter circuit are set to the 2n Numeric data fetching means (FIGS. 23 (a) to (d)) for fetching the 2n-bit numeric data as lower numeric data which is the lower n bits of the bit numeric data;
The lower numeric data and the upper numeric data fetched by the numeric data fetching means are arranged in different orders, and the upper numeric data and the lower numeric data are interchanged with each other so that the specific lower numeric data and the specific upper numeric data are respectively exchanged. As a data conversion means (FIG. 23 (e)) for storing in the specific upper area and the specific lower area provided in the storage means provided in the game control means,
Determining that the game control means includes numerical data obtained by performing a predetermined operation on the numerical data stored in the specific upper area and setting the numerical data obtained as a result of the predetermined operation as upper n bits. Numerical data input means (FIG. 21 (e), (f), (g), (h), (j)) for inputting into the area may be further provided,

The pre-determining means derives the winning display result by determining whether or not the determination numerical data input to the determination area indicates that derivation is allowed for each type of the winning display result. It can be decided whether or not to allow this.

  Here, the numerical data for determination used in the determination by the pre-determining means does not use the numerical data corresponding to the data signal generated by the counter circuit as it is, but first, the arrangement of the lower n bits of the data signal generated by the counter circuit. The numerical data with the order changed is stored as the specific upper numerical data, and the numerical data with the upper n bits arranged in the rearranged order is stored as the specific lower numerical data in the specific upper area and the specific lower area, respectively. Then, an exclusive OR operation of the numerical data stored in the specific lower area is performed as a predetermined operation on the numerical data stored in the specific upper area.

  By the way, the numerical data corresponding to the data signal generated by the counter circuit has a continuous value every time the pulse signal is input. In the numerical data in which the upper n bits and the lower n bits of the data signal generated by the counter circuit are exchanged, the value is more varied than the numerical data corresponding to the data signal generated by the counter circuit. The value will be periodic. Furthermore, even in numerical data in which the order of bits is different, the periodicity remains in the change in value.

  On the other hand, as in the numerical data for determination in the slot machine of the present invention, the exclusive OR operation with the numerical data stored in the specific lower area for the numerical data stored in the specific upper area, By using this as the upper n-bit data in particular, it is possible to eliminate the periodicity remaining in the numerical data composed of the specific upper numerical data and the specific lower numerical data. Thereby, even if the determination value that determines that the derivation of the winning display result is allowed is set in a range in which the value is continuous over two or more, the player does not aim for the determination of the predetermining means. Can be prevented.

  Depending on the configuration of the game control means, it may not be possible to perform an operation such as an exclusive OR operation using the specific upper area and the specific lower area provided in the storage means as they are. For example, in the case where the game control means is constituted by a microcomputer having a one-address instruction set, the numerical data input means loads numerical data of a specific upper area into an accumulator (general-purpose register), and the numerical data of the accumulator Is subjected to an exclusive OR operation with the numerical data in the specific lower region, and the numerical data obtained as a result of the operation is stored in the accumulator, and the numerical data stored in the accumulator is input to the upper n bits of the determination region. Here, when the numerical data of the specific upper area is loaded into the accumulator, the accumulator acts as the specific upper area.

  In the storage unit, the specific upper area and the specific lower area may be the same as the determination area. For example, when the numerical data of the specific lower area is exclusive ORed with respect to the numerical data of the specific upper area for each bit, and the numerical data of the result is stored in the specific upper area, the specific upper area is That is, the upper n bits of the determination area.

Furthermore, it is preferable that the frequency of the pulse signal generated by the pulse generation circuit is different from the frequency of the operation clock (operation clock of the CPU 111) for operating each means of the slot machine.
Here, it is more preferable that the frequency of the pulse signal is larger than the frequency of the operation clock.

  In this case, the update of the (first) numerical data input by the data signal latched from the counter circuit is not synchronized with the processing cycle of each means constituting the slot machine. In particular, by making the frequency of the pulse signal larger than the frequency of the operation clock, the update speed of the numerical data input by the data signal latched from the counter circuit can be increased, which is more effective in preventing aiming.

It is installed. A random number generation circuit 115, a sampling circuit 116, and other circuits are mounted.

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

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

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

  The random number generation circuit 115 is configured by a counter that counts up and updates the value every time a predetermined number of pulses are generated, as will be described later, and the sampling circuit 116 acquires the numerical value counted by the random number generation circuit 115. . The random number generation circuit 115 is provided for each type of random number used for the progress of the game, and a range of numerical values to be counted for each type of random number is determined. The CPU 111 sends an instruction to the sampling circuit 116 according to the processing to acquire the numerical value indicated by the random number generation circuit 115 as a random number (hereinafter, this function is referred to as a hardware random number function). 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, and 63R 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, a bonus notification lamp 66, and winning display lamps 45a to 45d. A reel lamp 3LP is connected via a reel lamp relay substrate 104. The control unit of the effect control board 102 performs these effects by controlling these parts.

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

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

  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 setting key switch 92 is turned on and the power is turned on, the setting value can be changed. When the setting switch 91 is operated during a period during which the setting value can be changed, the setting value is updated by 1 (when the operation is further 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 storage area provided in the RAM 112.

  In the slot machine 1, a winning is awarded when the symbols are arranged on any of the active lines 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 that involve the transition of gaming status, small roles that involve the payout of medals, and no need to set the number of bets. There is a re-player who can start the next game. In order to win each winning combination determined according to the gaming state, it is necessary to win an internal lottery to be described later and to set a winning flag for the winning combination in the RAM 112.

  FIG. 5A 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. As a combination in the slot machine 1, a regular bonus, a big bonus (1), a big bonus (2), JACIN as a special combination, a bell and cherry as a small combination, and a replay as a re-playing combination are defined.

  In the regular bonus game state, bells and cherries, which are small roles, are determined as winning combinations, and are subject to lottery in the internal lottery in the regular bonus. In the big bonus game state, JACIN, which is a special combination, and Bell and Cherry, which are small combinations, are determined as winning combinations, and are subject to lottery in an internal lottery in the big bonus. In the normal gaming state, regular bonuses that are special roles, big bonus (1) and big bonus (2), bells and cherries that are small roles, and replays that are replaying roles (in order to distinguish from replays in RT, Replay) is defined as a winning combination, and is selected for lottery in an internal lottery in a normal gaming state.

  If you win the regular bonus, big bonus (1) or big bonus (2) in the normal gaming state and do not win in that game, the winning flag will be carried over and the gaming state will change to RT (Replay Time) from the next game Transition. In other words, the regular bonus winning flag, the big bonus (1) winning flag, and the big bonus (2) winning flag also serve as the RT flag. In RT, the small role Bell and Cherry, and the replay role Replay (referred to as RT replay to distinguish from normal time replay) are determined as winning roles, and are subject to lottery in the internal lottery at RT. It is said. The normal-time replay and the RT-time replay have different winning probabilities because the storage areas for the number of determination values described later are different, but the other points are common.

  The regular bonus is awarded when a combination of “red 7-white 7-blue 7” is aligned on any of the active lines (eight) 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 “red 7-white 7-white 7” is arranged in any of the active lines (eight) in the normal gaming state or RT. The big bonus (2) is awarded when a combination of “red 7-blue 7-blue 7” is aligned on either of the active lines (eight) in the normal gaming state or RT. When the big bonus (1) or big bonus (2) is won, the gaming state shifts to a big bonus (1) and a big bonus (2) (collectively referred to as a 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.

  JACIN is awarded when a combination of “Bell-Cherry-Cherry” is placed on any of the active lines (eight) in the small role game in the big bonus, but in a game 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 big bonus (1) and the big bonus (2) have the same game characteristics, but there is a difference in the upper limit of the number of medals that the player can acquire. More specifically, the upper limit of the number of medals earned in the big bonus (1) is 180, and the big bonus (1) when the total number of payouts exceeds 165 which is obtained by subtracting 15 which is the maximum payout number at the time of winning. Ends. The upper limit of the number of medals earned in the big bonus (2) is 360, and the big bonus (2) ends when the total number of payouts exceeds 345, which is obtained by subtracting 15 which is the maximum payout number at the time of winning. When the regular bonus in the big bonus reaches 165 or 345, the regular bonus is terminated together with the big bonus.

  The Bell is awarded when the combination of “Red 7-Bell-Bell” is aligned on any of the active lines (eight) in any gaming state, and 15 medals are paid out. Cherry is awarded when the “Cherry” symbol is derived to any of the active lines (eight) for the left reel 3L in any gaming state, and when the bet number is 1, 15 medals are awarded, When the number of bets is 3, one medals per qualifying line is always derived from four activating lines, so a total of four medals are paid out. Since the bet number 1 is set only with the regular bonus, the number of medals to be paid out when winning the cherry can be changed to 15 by changing the gaming state to the regular bonus.

  Replays are awarded when the combination of “Red 7-JAC-Cherry” is placed on either of the active lines (eight) in the normal gaming state or RT, but regular bonuses and big bonuses (small game and Regular bonus) will not be replayed even if this combination is available. 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.

  Reference of the combination according to the gaming state is performed according to the winning combination table according to gaming state shown in FIG. That is, when the gaming state is a regular bonus (including the case where it is provided during the big bonus), the bell and cherry are sequentially read out as the internal lottery target roles, and the gaming state is in the small role game during the big bonus. Sometimes, JACIN, bell, and cherry are sequentially read out as the target combination for internal lottery.

  When in the normal gaming state, the regular bonus, the big bonus (1), the big bonus (2), the bell, the cherry, and the normal time replay are sequentially read out as the internal lottery target roles. When the gaming state is RT, the bell, cherry, and RT replay are sequentially read out as the internal lottery target roles. The RT is controlled when a regular bonus winning flag, a big bonus (1) winning flag, or a big bonus (2) winning flag is set in a game before the previous time, and the game is carried over without winning based on the flag. It is in a gaming state, and the regular bonus, the big bonus (1), and the big bonus (2) are not overlapped and are not subject to the internal lottery.

  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. 5B 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 for each combination is registered corresponding to the number of bets (BET) set by the player in the game. This is because even with the same combination, the winning probability in the regular bonus may be different. In addition, the number of determination values according to the number of bets for each combination may be common regardless of the set value, or may be different depending on the set value. If the number of determination values is common regardless of the set value, a common flag is set (value is set to “1”).

  The regular bonus, the big bonus (1), and the big bonus (2) are the roles that are subject to the internal lottery only in the normal gaming state, and store the number of judgment values corresponding to the bet number 3 in the normal gaming state. The address is registered. For these combinations, the value of the common flag is 0, and the storage address for the number of determination values is individually registered according to the set value. JACIN is an internal lottery target only in the small bonus game in the big bonus, and the storage address of the number of determination values corresponding to the number of bets in the small bonus game is registered. 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.

  The normal time replay is a combination that is subject to internal lottery only in the normal gaming state, and the storage address of the number of determination values corresponding to the bet number 3 in the normal gaming state is registered. 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. The RT replay is an internal lottery target only in RT, and a storage address of the number of determination values corresponding to the betting number 3 in the normal gaming state is registered. 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.

  Bells and cherries are internal lottery targets in any gaming state, the storage address for the number of judgment values corresponding to the regular bet number 1 in the regular bonus, and the number of bets in the normal gaming state or small role game A storage address of the number of determination values corresponding to 3 is registered. For cherry, the common flag is 1, and the storage address of the common number of determination values is registered corresponding to the number of bets regardless of the set value. For the bell, the common flag is 0, and the storage address of the determination value number is individually registered according to the set value corresponding to each bet number.

  In the role-specific table, the number of medals to be paid out when winning each role is also registered. Of course, the combination of the medal to be paid out when winning a prize is the small combination of bell and cherry. The regular bonus, the big bonus (1), the big bonus (2), and the winning of JACIN are accompanied by a transition of the gaming state, and are not eligible for paying out medals. Replay does not involve the payout of medals, but the medals used for setting the number of bets in the next game are no longer necessary, so that it is substantially the same as the payout of 3 medals.

  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 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, 31 that is a value stored here is acquired as the number of determination values. . Addresses ADD + 2, ADD + 4, ADD + 6, ADD + 8, and ADD + 10 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.

  The addresses ADD + 12, ADD + 14, ADD + 16, ADD + 18, ADD + 20, and ADD + 22 are addresses that are referred to when the internal lottery target is the big bonus (1) and the set value is 1-6. The addresses ADD + 24, ADD + 26, ADD + 28, ADD + 30, ADD + 32, and ADD + 34 are addresses that are referred to when the internal lottery target role 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 + 36 is an address that is referred to regardless of the set value when the target combination of the internal lottery is JACIN, and 4311 is acquired as the number of determination values regardless of the set value.

  The addresses ADD + 38, ADD + 40, ADD + 42, ADD + 44, ADD + 46, and ADD + 48 are addresses that are referred to when the bet number is 1, that is, when the target character of the internal lottery is a bell and the set value is 1 to 6 in the regular bonus. is there. Since the same value is registered in each of the addresses ADD + 38 and ADD + 40, ADD + 42 and ADD + 44, and ADD + 46 and ADD + 48, the set value 1 and the set value 2, the set value 3 and the set value 4 and the set value are set at the regular bonus time. With 5 and the set value 6, the winning probability of the bell is the same.

  Addresses ADD + 50, ADD + 52, ADD + 54, ADD + 56, ADD + 58, and ADD + 60 are each when the bet number is 3, that is, in the normal gaming state or in the small role game, the internal lottery target is the bell and the set value is 1 to 6 This address is referred to by Since different values are registered in the addresses ADD + 50, ADD + 52, ADD + 54, ADD + 56, ADD + 58, and ADD + 60, in the normal gaming state or the small role game, the winning probability of the bell differs depending on the set value. .

  The address ADD + 62 is an address that is referred to regardless of the set value when the bet number is 1, that is, when the target character of the internal lottery is cherry in the regular bonus. The address ADD + 64 is an address that is referred to regardless of the set value when the number of bets is 3, that is, in the normal gaming state or in the small role game, when the target combination of the internal lottery is cherry. The number of determination values for cherry is registered according to the number of bets, but since the same value is registered, the winning probability of cherry is the same in any gaming state.

  The address ADD + 66 is an address that is referred to regardless of the set value when the target of the internal lottery is replay (in this case, normal replay) in the normal gaming state. The address ADD + 68 is an address that is referred to regardless of the set value because the target of the internal lottery is replay (here, replay at RT) in RT. Since a value larger than the address ADD + 66 is registered in the address ADD + 68, the replay winning probability in RT is higher than the replay winning probability in the normal gaming state.

  FIGS. 7A to 7C are diagrams illustrating an example of the relationship between the value of the random number for internal lottery and the number of determination values of each combination and the winning combination. FIG. 7A shows an example in a normal gaming state, FIG. 7B shows an example in a small role game, and FIG. 7C shows an example in a regular bonus. FIGS. 7A to 7C show examples in which the set value is 6, and FIG. 7A shows a regular bonus winning flag, a big bonus (1) winning flag, and a big An example in which none of the bonus (2) winning flags is set is shown. In the figure, examples other than this are omitted, but similarly, the relationship between the value of the random number for internal lottery and the number of judgment values of each combination and the winning combination will be determined.

  For example, as shown in FIG. 7 (a), in the normal gaming state, the roles that are subject to the internal lottery are regular bonus, big bonus (1), big bonus (2), bell, cherry, and replay. In the setting value 6, the number of determination values is 31, 30, 30, 3562, 269, 2245. First, the regular bonus that is the target of the internal lottery is won when 16353 to 16383, in which the addition result overflows by adding 31 judgment values, is acquired as a random number for internal lottery.

  Next, the Big Bonus (1), which is the target of the internal lottery, adds 61, which is the sum of the regular bonus judgment value number 31 and the big bonus judgment value number 30, and the addition result overflows 16323. A win is made when ˜16352 is acquired as a random number for internal lottery. Similarly, big bonus (2) is obtained when 16293-16322 is acquired as a random number for internal lottery, bell is acquired when 127331-16292 is acquired as a random number for internal lottery, cherry is 12462 When 12730 is acquired as a random number for internal lottery, the replay is determined to be a win when 10217 to 12461 are acquired as random numbers for internal lottery.

  The approximate winning probabilities calculated for these combinations based on the number of judgment values are 1 / 528.5 for each of the regular bonus, big bonus (1), big bonus (2), bell, cherry, and replay. 1 / 546.1, 1 / 546.1, 1 / 4.6, 1 / 60.9, and 1 / 7.3. When 0-10216 is acquired as a random number for internal lottery, all combinations are lost.

  In addition, as shown in FIG. 7B, in the small role game, JACIN, Bell, and Cherry are subject to internal lottery, and the numbers of determination values are 4311, 3562, and 269, respectively, 12073 to 16383, 8511. When ˜12072 and 8242-8510 are acquired as random numbers for internal lottery, the winning combination is determined. In addition, the approximate winning probabilities for each combination are 1 / 3.8, 1 / 4.6, and 1 / 60.9. When 0 to 8241 are acquired as random numbers for internal lottery, all combinations are lost.

  In addition, as shown in FIG. 7C, in the regular bonus, bells and cherries are subject to internal lottery, and the numbers of determination values are 15919 and 269, so 465 to 16383 and 196 to 464 are internal lotteries. When it is acquired as a random number for use, it is determined to be a winner. In addition, the approximate winning probabilities for each combination are 1 / 1.03 and 1 / 60.9. When 0 to 195 are acquired as random numbers for internal lottery, all combinations are lost.

  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 extracted from the random number generation circuit 115 or processed from 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. 8A 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 eighth bit data signal is inverted from the H level to the L level, the level of the ninth bit data signal is alternately inverted between the H level and the 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. 8B is an explanatory diagram until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. The random number extracted from the random number generation circuit 115 is stored in a 16-bit general-purpose register 111GR included in the CPU 111.

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

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

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

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

  Next, stop control of the reels 3L, 3C, 3R will be described. The reels 3L, 3C, and 3R can be stopped in an arbitrary order, but are referred to as a first reel, a second reel, and a third reel in the order in which they are stopped. As described above, the rotation of the reels 3L, 3C, and 3R is stopped within the range of the maximum stop delay time of 190 milliseconds from when the stop buttons 12L, 12C, and 12R are operated, that is, within the pull-in range within 4 frames. . Since the pull-in range when the reels 3L, 3C, and 3R are stopped is 4 frames, the symbols that can be stopped are the symbols that are displayed when the stop buttons 12L, 12C, and 12R are operated and the symbols that are in the range of the next 4 frames. It will be chosen from the inside.

  The selection of symbols is in accordance with the winning status of each combination in the RAM 112. That is, the symbol is selected so that the symbol of the combination for which the winning flag is set is derived on any effective line, and the symbol of the symbol for which the winning flag is not set is not derived for any effective line. The symbol is selected. When the replay winning flag is set over the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag, the derivation of the latter has priority over the former. When the cherry winning flag or the bell winning flag is set over the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag, the former is prioritized over the latter.

  For example, on the active line set on a straight line (for example, the horizontal direction and the diagonal direction in the upper, middle, and lower stages), the symbols constituting the winning display mode by the time the second reel is stopped are displayed as the tempered (ie, the third reel). Even if the winning display mode is derived on the active line (except for), in order to win the winning combination, the symbol of the winning position is positioned on the active line that is tempered, or the position The stop button must be operated when the symbol of the role is within the next 4 frames.

  On the other hand, in the slot machine 1 according to this embodiment, the effective line of the variable display device 2 is constituted by a combination of the upper or lower stage of each reel as shown in FIG. For this reason, in order to win a winning combination with a winning flag set, it is only necessary that the symbol of the winning combination can be stopped at either the upper stage or the lower stage, and the symbols constituting the winning display mode are tempered. Sometimes, when the symbol composing the role is located in the lower row, or when there is a symbol of the role within the next 6 frames from the lower row (if it is 6 frames ahead, it can be stopped in the upper row), the stop button is operated It will do.

  A symbol that can be derived to the middle stage of the reels 3L, 3C, and 3R within the range of the maximum stop delay time of 190 milliseconds can be always derived to either the lower stage or the upper stage within the range of the maximum stop delay time. . For this reason, the meaning of deriving a specific symbol to the middle stage of the reels 3L, 3C, 3R is small, and the effective line including the middle stage is set in the variable display device 2 in order not to increase the number of effective lines unnecessarily. Not to be.

  For any of the reels 3L, 3C, and 3R, a combination in which symbols are arranged within 7 frames can be derived to the variable display device 2 without being missed if the winning flag is set. As shown in the symbol arrangement of FIG. 2, the bell, cherry, replay, and JACIN are such unmissable roles, but the regular bonus, big bonus (1), and big bonus (2) are the stop buttons 12L and 12C. , 12R may be missed depending on the operation timing.

  Further, in the symbol arrangement of FIG. 2, the symbol “white 7” or “blue 7” constituting the display mode of the regular bonus, the big bonus (1) or the big bonus (2) for the inner reel 3C is derived to the upper or lower level. When this is done, the symbol “JAC” constituting the display mode of the replay is always derived to the lower stage or the upper stage. “Red 7” for the left reel 3L constitutes a display form of a regular bonus, a big bonus (1) or a big bonus (2) and also a display form of a replay.

  Therefore, if the left and right reels 3L and 3C are stopped (in no particular order) as the first and second reels, if the regular bonus, the big bonus (1), or the big bonus (2) are tempered, they can be replayed at the same time. Will be tempered too. When the regular bonus, big bonus (1) or big bonus (2) is won, the right reel 3C is operated with the regular bonus, big bonus (1) or big bonus (2) and replay double-tempered in this way. If you can stop “White 7” or “Blue 7” at the top or bottom depending on the type of the winning combination, you will be awarded a bonus, otherwise you will be awarded a replay (replay is also won Is a requirement).

  Next, the setting of the bet number and the settlement of credit will be described. While the game is not being executed, the bet number is set and credits are allowed to be settled. In this state, medals are inserted or the bet number can be set using credits. Yes. In a state where the bet number can be set and a prescribed number of bets corresponding to the gaming state is not set, the bet number is incremented by one every time a medal is detected. Further, if a prescribed number of bets corresponding to the gaming state is set, a credit is added by one each time a medal is detected. When the credit reaches the upper limit (50 sheets), the flow path switching solenoid 49 is turned OFF, the flow path of the inserted medal is switched to the payout side, and the insertion of the medal is prohibited.

  If the credit remains, the number of bets is set by operating the single BET button 14 or the MAXBET button 15, and the amount is subtracted from the credit. Further, if the credits remain or the bet number is set, it is used for setting the medal and the bet amount stored as credits by driving the hopper motor 82 by operating the settlement button 16. The medals are paid out and returned to the player, and the credits and the number of bets are subtracted according to the medals paid out.

  When the start lever 11 is operated and the game is started in a state where the setting of the bet amount and the credit settlement are permitted, the setting of the bet amount and the credit settlement are prohibited at that time. More specifically, the flow path switching solenoid 49 is turned OFF, the flow path of the inserted medal is switched to the payout side, and the operations of the single BET button 14, the MAXBET button 15, and the settlement button 16 are invalidated. The time when the game is started is not the time when rotation of the reels 3L, 3C, 3R is started, but when the control is shifted to start rotation of the reels 3L, 3C, 3R by operating the start lever 11. is there.

  When the rotation of the reels 3L, 3C, 3R is stopped and the display result is derived to the variable display device 2 and no small prize winning with a medal payout has occurred, the display result of the variable display device 2 is derived It is determined that the game is over. If the small role winning has occurred, it is determined that the game is over at the time when the medal payout accompanying the small role winning is completed. When it is determined that the game is over, the setting of the bet number and the prohibition of the credit settlement are canceled at that time, and the setting of the bet number and the credit settlement are permitted. As an exception, when a replay winning occurs, the bet number is automatically set, so that the setting of the bet number and the settlement of the credit remain prohibited.

  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 as a basic command, the winning status notification command sent after the internal lottery is performed, the rotation of the reels 3L, 3C, 3R. There are a reel stop command that is sent when the game stops, a winning information command that is sent after the display result is derived to the variable display device 2, and a status command that is sent after the game is over and before moving to the next game. .

  The winning status notification command indicates the setting status of the winning flag in the RAM 112. 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 status command indicates a gaming state (normal, RT, regular bonus, big bonus) applied in the next game.

  The CPU 121 of the effect control board 102 performs various effects based on the commands sent from the CPU 111 of the game control board 101 as described above. As an effect performed by the control of the CPU 121, an effect particularly performed in the liquid crystal display 4 is an effect of deriving a display mode corresponding to the symbol derived to the variable display device 2 by the change / stop of the virtual reel.

  Three virtual reels are provided corresponding to the reels 3L, 3C, and 3R that constitute the variable display device 2, and each of the virtual reels displays a symbol in three stages of upper, middle, and lower stages. All three virtual reels are arranged with the same 21 symbols as the reels 3L, 3C, 3R of the variable display device 2. Each virtual reel is rotated in a fixed direction at the same speed (80 rpm) as the reels 3L, 3C, 3R.

  There are six types of symbols arranged on each virtual reel: “BAR”, “7”, “JAC”, “Bell”, “Watermelon”, and “Cherry”. On the virtual reel, three effective lines and two diagonal lines are set in the horizontal direction of the upper, middle, and lower stages. When any winning occurs according to the display result of the variable display device 2, symbols corresponding to the type of winning are arranged on any of the five effective lines.

  The design of each virtual reel starts to change when a winning status notification command is received (substantially the same as when the start lever 11 is operated), and when a reel stop command is received (substantially the stop button 12L, The change is stopped until 190 milliseconds elapse from the same time as when 12C and 12R are operated. Accordingly, in each virtual reel, the number of symbols drawn from the operation of the stop buttons 12L, 12C, and 12R is the same four frames as the reels 3L, 3C, and 3R of the variable display device 2.

  Unlike the symbol arrangement on the reels 3L, 3C, and 3R constituting the variable display device 2, the symbol arrangement on the virtual reel includes a standard arrangement and an arrangement other than the standard arrangement. Which arrangement is applied is determined by a lottery according to the gaming state and the winning situation, but when at least one of the regular bonus, the big bonus (1) or the big bonus (2) is won, Non-standard sequences apply.

  FIG. 9A is a diagram showing symbols derived to the virtual reel of the liquid crystal display 4 according to the type of winning combination. As shown in the drawing, when a regular bonus is won, a display mode of “BAR-BAR-BAR” is derived on any active line. When winning the big bonus (1) or the big bonus (2), the display mode of “7-7-7” is derived. When JACIN is won and when a replay is won, the display mode of “JAC-JAC-JAC” is derived. When winning the bell, the display mode of “bell-bell-bell” or “watermelon-watermelon-watermelon” is derived. When winning a cherry, a display mode of “cherry-ANY-ANY” (ANY indicates any symbol) is derived.

  FIG. 9B is a diagram showing a selection table for a virtual reel symbol arrangement. There are four types of arrangements other than the standard arrangement: regular bonus + bell, regular bonus + replay, big bonus + bell, and big bonus + replay. Among these, for example, the big bonus + bell arrangement is always selected when the big bonus (1) winning flag or the big bonus (2) winning flag is carried over and the bell winning flag is also set. Is an array.

  When only the regular bonus winning flag is set, or when the regular bonus winning flag and the cherry winning flag are set, the regular bonus + bell arrangement and the regular bonus + replay arrangement are 128/256, 128, respectively. Selected with a probability of / 256. When the regular bonus winning flag and the bell winning flag are set, the regular bonus + bell arrangement is selected with a probability of 256/256. When the regular bonus winning flag and the replay winning flag are set, the regular bonus + replay arrangement is selected with a probability of 256/256.

  When only the big bonus (1) winning flag or big bonus (2) winning flag is set, or when the big bonus (1) winning flag or big bonus (2) winning flag and cherry winning flag are set The big bonus + bell arrangement and the big bonus + replay arrangement are selected with a probability of 128/256 and 128/256, respectively. When the big bonus (1) winning flag or the big bonus (2) winning flag and the bell winning flag are set, the big bonus + bell arrangement is selected with a probability of 256/256. When the big bonus (1) winning flag or the big bonus (2) winning flag and the replay winning flag are set, the big bonus + replay arrangement is selected with a probability of 256/256.

  When the game state is a big bonus or a regular bonus in a winning situation other than the above, the standard arrangement is selected with a probability of 256/256. When the game state is normal or RT in a winning situation other than the above, the standard arrangement, the regular bonus + bell arrangement, the regular bonus + replay arrangement, the big bonus + bell arrangement, and the big bonus + replay arrangement are 252 respectively. Selection is made with the probability of / 256, 1/256, 1/256, 1/256, 1/256.

  FIG. 10 is a diagram showing a standard sequence. In the standard arrangement, in each of the virtual reels 4L, 4C, and 4R respectively corresponding to the reels 3L, 3C, and 3R of the variable display device 2, “bell” and “JAC” are arranged at intervals of 5 frames or less. Yes. In addition, “cherries” are arranged at intervals of 5 frames or less for the left virtual reel 4L. In the range of the maximum stop delay time of 190 milliseconds, it is possible to draw 4 frames. Be sure to select “Bell” among the 5 frames that are the combination of the symbols displayed at the time of receiving the reel stop command and the 4 frames in the drawing range. ”,“ JAC ”can be stopped at any position in the upper, middle, and lower stages. For the left virtual reel 4L, “cherry” can also be stopped at any position in the upper, middle, and lower stages.

  As with the standard arrangement, regardless of the operation timing of the stop button 12L, both “Bell” and “JAC” can be stopped at any position within the maximum stop delay time of 190 milliseconds. If the “cherry” can be stopped at any one of the upper, middle, and lower stages, these three types of symbols occupy 13 frames in the left virtual reel 4L. Then, the remaining number of frames that can be placed with the symbol is only 8 frames, and if “7” can be stopped at any position regardless of the operation timing of the stop button 12L, “BAR” can be placed at any position. It can no longer be arranged so that it can be stopped. The reverse is also true.

  For example, taking the left virtual reel 4L as an example, the symbol “7” has only one symbol No. 20, and the symbol “BAR” has only two symbols No. 15 and No. 7. Although it is displayed in a plane in the figure, the symbol next to the symbol of No. 20 on the virtual reel 4L becomes No. 0 and the symbol arrangement circulates. The interval from No. 20 to No. 7 “7” is 21 frames, that is, there are other symbols for 20 frames between them. In addition, the interval from “BAR” of No. 7 to the next “BAR” of No. 15 is 8 frames, and there are other symbols for 7 frames between them. The interval to “BAR” of No. 7 is 13 frames, and there are other symbols for 12 frames in between.

  For the middle and right virtual reels 4C and 4R, the symbols that need to be arranged are always 10 frames in total, “Bell” and “JAC”, so both “7” and “BAR” are arranged within 5 frames each. (However, in the standard arrangement of FIG. 10, this is not necessarily the case. For example, for the inner reel 3C, “7” next to “7” in No. 7 is No. 16. The interval is 9 frames). However, in any case, it is impossible to arrange at least one of “7” and “BAR” within 5 frames for the left reel 3L.

  Then, when either the regular bonus, the big bonus (1) or the big bonus (2) is won, the variable display device 2 wins the regular bonus, the big bonus (1) or the big bonus (2). However, the virtual reel of the liquid crystal display 4 has a situation in which a symbol corresponding to the virtual reel cannot be derived within the maximum stop delay time of 190 milliseconds. For this reason, when at least one of the regular bonus, the big bonus (1), and the big bonus (2) is won, an arrangement other than the standard arrangement is required as an arrangement of symbols on the virtual reel.

  On the other hand, for example, in the variable display device 2, even when a regular bonus, a big bonus (1) or a big bonus (2) is won, there is only one type of symbol “7” to be derived on the effective line of the virtual reel. Then, even if “Bell”, “JAC”, and “Cherry” occupy 13 frames, it is possible to arrange “7” so that it can be stopped at an arbitrary position regardless of the operation timing of the stop button 12L. it can. However, for players who are familiar with the general arrangement of symbols on variable display devices that have a limited number of bonus symbols of the same type so that they may be missed due to the need for technical intervention, the number of bonus symbols is limited. There is a risk of feeling uncomfortable with too many virtual reels.

  Further, in terms of the total number of games, there are many cases where the regular bonus, the big bonus (1) or the big bonus (2) is not won. In such a case, it is not necessary to arrange bonus symbols on the virtual reel effective line in the first place. Therefore, in order not to make the player feel as uncomfortable as possible with respect to the arrangement of symbols on the virtual reel, the same is applied when the regular bonus, the big bonus (1) or the big bonus (2) is not won. It is better to have an arrangement with a limited number of types of bonus symbols, and a standard arrangement is required as the symbol arrangement on the virtual reel.

  FIG. 11 is a diagram showing an arrangement of big bonus + bell. In the big bonus + bell arrangement, “7” is arranged at intervals of 5 frames or less in any of the virtual reels 4L ′, 4C ′, and 4R ′ corresponding to the reels 3L, 3C, and 3R of the variable display device 2, respectively. ing. “7” can be stopped at any position in the upper, middle, and lower tiers out of 5 frames including the symbols displayed at the time of receiving the reel stop command and 4 frames in the pull-in range. .

  In the left and right virtual reels 4L 'and 4R', "bell" is always arranged at a position two below "7". In the inner virtual reel 4C ', a "bell" is always arranged at a position immediately below "7". Therefore, for example, if “7” is stopped at the upper stage when the left and right virtual reels 4L ′ and 4R ′ are stopped, “7” and “Bell” are double-tempered. Further, when “7” is stopped at the upper stage for the left virtual reel 4L ′ or the right virtual reel 4R ′, and “7” is stopped at the upper stage or the middle stage for the middle virtual reel 4C ′, “7” and “bell” Will be a double temper. Further, for the left virtual reel 4L ', "cherry" is always arranged one or two above "7". When “7” is stopped at the lower stage for the left virtual reel 4L ′, “Cherry” can be stopped at either the upper stage or the middle stage.

  The Big Bonus + Replay arrangement is obtained by replacing “Bell” and “JAC” in the Big Bonus + Bell arrangement. In the regular bonus + bell arrangement, “7” and “BAR” in the big bonus + bell arrangement are interchanged. In the regular bonus + replay arrangement, “7” and “BAR” in the big bonus + bell arrangement are interchanged, and “bell” and “JAC” are interchanged.

  Hereinafter, a gaming operation in the slot machine 1 according to this embodiment will be described. In the following description, the term “game” means, in a narrow sense, from the operation of the start lever 11 until the reels 3L, 3C, 3R are stopped. However, when a game is played, the number of bets before the operation of the start lever 11 is set, and medals are paid out and the game state is shifted after the reels 3L, 3C, 3R are stopped. Is also included in the “game” in a broad sense. The command transmission from the game control board 101 to the effect control board 102 will be described only for those directly related to the present invention.

  FIG. 12 is a flowchart showing processing for one game executed by the CPU 111 of the game control board 101. 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 S1).

  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. A BET process for instructing the start is performed (step S2). Here, when the gaming state is a regular bonus (including the case where the bonus is 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 operated effectively. It becomes. 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 number of bets as in the previous game (3 in this embodiment) is automatically set by the replay flag (the replay flag is erased at this stage) and remains as it is. The start lever 11 becomes effective.

  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 S3). In this lottery process, a winning flag is set in the RAM 112 based on each lottery result. Details of the lottery process will be described later.

  When the lottery process ends, a reel fluctuation start process is performed (step S4). In the reel fluctuation start process, the reels 3L, 3C, and 3R in the previous game are processed 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. The motors 3ML, 3MC, and 3MR are driven to start rotation of all the left, middle, and right reels 3L, 3C, and 3R. Thereby, the symbols are variably displayed on the variable display device 2. Here, if the predetermined time has not elapsed since the start of rotation in the previous game, the process waits for rotation to start. Also, the timing of one game timer for the next game is started.

  Thereafter, reel fluctuation stop processing is performed (step S5). In the reel fluctuation stop process, after a predetermined condition is established from the start of reel rotation (the reference position is detected by the reel sensors 3SL, 3SC, 3SR after the rotation speed reaches a certain speed), the stop buttons 12L, 12C , 12R are enabled, and each is operated by the player, thereby stopping the driving of the reel motors 3ML, 3MC, 3MR and stopping the rotation of the reels 3L, 3C, 3R according to the setting state of the winning flag. Details of the reel fluctuation stop 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 active line corresponding to the bet number set in the BET process in step S2 A winning determination process for determining whether or not is performed (step S6). 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 S7). 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 not related to winning a prize (including processes related to erasing winning flags other than the big bonus (1) winning flag, big bonus (2) winning flag, regular bonus winning flag, and the end of the big bonus and regular bonus) Done. 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 S3 will be described in detail. FIG. 13 is a flowchart showing in detail the lottery process executed by the CPU 111 in step S3. In the lottery process, when a small role is won in the previous game, the payout display unit 21 lights up the scheduled payout number, so the payout display 51 is controlled to turn it off. If there is no lighting display of the number of payouts, the light-off state is only maintained (step S101).

  Next, random number acquisition processing, which will be described in detail later, is performed (step S102). In this random number acquisition process, the random number value for internal lottery is acquired based on the random number generated by the random number generation circuit 115.

  Next, in accordance with the current gaming state, the combinations registered in the winning combination table by gaming state in FIG. 5A are sequentially read (step S103). Further, the number of BETs set in step S2 is read, and the setting status of the common flag is acquired in the role-specific table of FIG. 5B for the role and the role corresponding to the read BET number (step S104). As a result, it is determined whether or not a common flag is set for the combination and the BET number (step S105).

  If the common flag is set, the determination value number stored in the address registered in the role-specific table of FIG. 5B is acquired for the role and the BET number (step S106). Then, the process proceeds to step S108. If the common flag is not set, the setting value set in the RAM 112 is read, and the determination stored in the address registered in the role-specific table corresponding to the setting value read for the role and the BET number The number of values is acquired (step S107). Then, the process proceeds to step S108.

  In step S108, the number of determination values acquired in step S106 or S107 is added to the random number value for internal lottery, and the result of addition is used as a new random number value for internal lottery. Here, it is determined whether or not an overflow has occurred when the number of determination values is added to the value of the random number for internal lottery (step S109). If an overflow occurs, a winning flag for the combination is set in the RAM 112 (step S110). Then, the process proceeds to step S112.

  If no overflow has occurred, it is determined whether there is a combination that has not yet been processed among the combinations determined for the gaming state (step S111). If there is a combination that has not yet been processed, the process returns to step S103, and the process continues with the next combination registered in the winning combination table according to gaming state as the processing target. If there is no combination not to be processed, the process proceeds to step S112.

  In step S112, the winning flag setting area in the RAM 112 is referred to generate a winning status notification command that can specify the setting status of the winning flag depending on whether the winning flag of each role is set or not. Send. Then, the lottery process is terminated, and the process returns to the flowchart of FIG.

  Next, the random number acquisition process in step S102 will be described in detail. FIG. 14 is a flowchart showing in detail the random number acquisition process executed by the CPU 111 in step S102. In the random number acquisition process, first, interrupt to the CPU 111 is prohibited (step S201). 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 S202).

  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 S203). Next, the value of the random number stored in the general-purpose register 111GR is ANDed with 8080h (step S204). 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 S205). Then, after permitting the interrupt prohibited in step S201 (step S206), the random number acquisition process is terminated, and the process returns to the flowchart of FIG.

  Next, the reel fluctuation stop process in step S5 will be described in detail. FIG. 15 is a flowchart showing in detail the reel fluctuation stop process executed by the CPU 111 in step S5. First, after the rotation of the reels 3L, 3C, and 3R reaches a constant speed, there is a predetermined condition that enables the reels 3L, 3C, and 3R to stop the reels 3L, 3C, and 3R to detect the reference position after all. It is determined whether or not it is established (step S301).

  If this predetermined condition is not satisfied, the process of step S301 is repeated, and the process waits for the predetermined condition to be satisfied. When this predetermined condition is satisfied, the left, middle, and right stop buttons 12L, 12C, and 12R are enabled, and the operation enable lamps 63L, 63C, and 63R are turned on (step S302). Then, the process proceeds to step S303.

  In step S303, it is determined whether or not the left stop button 12L is operated depending on whether or not the detection signal of the stop switch 42L is input. Here, even if the left stop button 12L is physically operated, if the operation has already been disabled, the stop button 12L is regarded as not being operated. If the left stop button 12L is not operated, the process proceeds to step S308 as it is.

  If it is determined that the left stop button 12L is operated, the left stop button 12L is disabled thereafter, and the operation enable lamp 63L is turned off (step S304). The left reel 3L is set according to the setting state of the winning flag of each combination in the RAM 112 and the type of symbols displayed on the variable display device 2 for the left reel 3L at the timing when the player operates the stop button 12L. A symbol to be derived is selected (step S305).

  Next, the reel to be stopped this time is the left reel 3L, and a reel stop command capable of specifying the symbol to be derived to the left reel 3L selected in step S305 is generated and transmitted to the effect control board 102. (Step S306). The required time from detection of the operation of the left stop button 12L to transmission of the reel stop command is a short time that can be ignored from the player's perception, and is substantially at the timing when the stop button 12L is operated. It will be sent. After transmitting the reel stop command, the rotation of the left reel 3L is stopped with the symbol selected in step S305 (step S307). Then, the process proceeds to step S308.

  In step S308, it is determined whether or not the middle stop button 12C is operated depending on whether or not the detection signal of the stop switch 42C is input. Here, even if the middle stop button 12C is physically operated, if the operation has already been disabled, it is considered that the stop button 12C has not been operated. If the middle stop button 12C is not operated, the process proceeds to step S313.

  If it is determined that the middle stop button 12C is being operated, the middle stop button 12C is disabled thereafter, and the operation valid lamp 63C is turned off (step S309). Then, according to the setting status of the winning flag of each combination in the RAM 112 and the type of symbol displayed on the variable display device 2 for the inner reel 3C at the timing when the player operates the stop button 12C, the inner reel 3C The symbol to be derived is selected (step S310).

  Next, the reel to be stopped this time is the inside reel 3C, and a reel stop command capable of specifying the symbol to be derived to the inside reel 3C selected in step S310 is generated and transmitted to the effect control board 102. (Step S311). It should be noted that the time required from the detection of the operation of the middle stop button 12C to the transmission of the reel stop command is also a short time that can be ignored from the player's perception, and substantially at the timing when the stop button 12C is operated. It will be sent. After transmitting the reel stop command, the rotation of the inner reel 3C with the symbol selected in step S310 is stopped (step S312). Then, the process proceeds to step S313.

  In step S313, it is determined whether or not the right stop button 12R is operated depending on whether or not the detection signal of the stop switch 42R is input. Here, even if the right stop button 12R is physically operated, if the operation has already been disabled, the stop button 12R is regarded as not being operated. If the right stop button 12R has not been operated, the process directly proceeds to step S318.

  If it is determined that the right stop button 12R is being operated, the right stop button 12R is subsequently disabled, and the operation enable lamp 63R is turned off (step S314). Then, the right reel 3R is set according to the setting status of the winning flag of each combination in the RAM 112 and the type of symbols displayed on the variable display device 2 for the right reel 3R at the timing when the player operates the stop button 12R. The symbol to be derived is selected (step S315).

  Next, the reel to be stopped this time is the right reel 3R, and a reel stop command capable of specifying the symbol to be derived to the right reel 3R selected in step S315 is generated and transmitted to the effect control board 102. (Step S316). Note that the time required from the detection of the operation of the right stop button 12R to the transmission of the reel stop command is also a short time that can be ignored from the player's perception, and substantially at the timing when the stop button 12R is operated. It will be sent. After transmitting the reel stop command, the rotation of the right reel 3R is stopped with the symbol selected in step S315 (step S317). Then, the process proceeds to step S318.

  In step S318, it is determined whether all the left, middle and right reels 3L, 3C, 3R are stopped. If any one of the reels 3L, 3C, 3R is not stopped, the process returns to step S303. When all of the reels 3L, 3C, and 3R are stopped, the reel fluctuation stop processing is ended and the process returns to the flowchart of FIG.

  Next, the winning determination process in step S6 will be described in detail. FIG. 16 is a flowchart showing in detail the winning determination process executed by the CPU 111 in step S6. First, it is determined whether or not the display mode of the big bonus (1) (red 7-white 7-white 7) is derived on any active line (step S401). If the display mode of the big bonus (1) is derived, the big bonus medium flag is set in the RAM 112 and the big bonus (1) winning flag set in the RAM 112 is erased. Also, the big bonus end number is set to 165 and stored in a predetermined area of the RAM 112. Further, the output of the big bonus medium signal is started from the external output board 105 and the HIT lamp 54 is turned on (step S402). Then, the process proceeds to step S415.

  When the display mode of the big bonus (1) is not derived, it is determined whether or not the display mode of the big bonus (2) (red 7-blue 7-blue 7) is derived on any active line. (Step S403). If the display mode of the big bonus (2) is derived, the big bonus medium flag is set in the RAM 112 and the big bonus (2) winning flag set in the RAM 112 is deleted. Also, the big bonus end number is set to 345 and stored in a predetermined area of the RAM 112. Further, the output of the big bonus medium signal is started from the external output board 105 and the HIT lamp 54 is turned on (step S404). Then, the process proceeds to step S415.

  If the display mode of the big bonus (2) is not derived, it is determined whether or not the display mode of the regular bonus (red 7-white 7-blue 7) is derived on any active line (step S405). ). If the display mode of the regular bonus has been derived, the regular bonus flag is set in the RAM 112 and the regular bonus winning flag set in the RAM 112 is erased. Further, the regular bonus medium signal is started to be output from the external output board 105 and the HIT lamp 54 is turned on (step S406). Then, the process proceeds to step S415.

  If the display mode of the regular bonus is not derived, it is determined whether or not the JACIN display mode (bell-cherry-cherry) is derived on any active line (step S407). If the display mode of JACIN is derived, a regular bonus medium flag is set in the RAM 112. In this case, a regular bonus medium flag is also set on top of the big bonus medium flag. Further, a regular bonus medium signal is output from the external output board 105 (step S408). Then, the process proceeds to step S415.

  If the JACIN display mode is not derived, it is determined whether or not the replay display mode (red 7-JAC-cherry) is derived on any active line (step S409). If the replay display mode has been derived, a replay flag is set in the RAM 112 (step S410). This replay flag is deleted when the bet number is automatically set in the next game. Then, the process proceeds to step S415.

  If the display mode of replay is not derived, it is determined whether or not the bell display mode (red 7-bell-bell) is derived on any active line (step S411). If the display mode of the bell is derived, 15 is set as the planned payout number of medals, and the payout display unit 51 is controlled to display 15 of the planned payout number on the payout display unit 21 (step S412). . Then, the process proceeds to step S415.

  If the bell display mode is not derived, it is determined whether or not the cherry display mode (cherry-ANY-ANY) is derived on any effective line (step S413). If the display mode of cherries has been derived, 15 (in regular bonus) or 4 (normal game state or small role game) is set as the planned payout number of medals according to the bet number set in step S2. By controlling the payout display 51, the payout display unit 21 displays 15 or 4 of the planned payout number (step S414). Then, the process proceeds to step S415.

  In step S415, a winning information command indicating the winning combination is generated and transmitted to the effect control board 102 when there is a winning and when there is a winning. Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  Next, the payout process in step S7 will be described in detail. FIG. 17 is a flowchart showing in detail the payout process executed by the CPU 111 in step S7. First, the number corresponding to the winning combination is determined by controlling the hopper 80 and discharging the medals one by one while subtracting the planned payout number by 1 until the planned payout number set in the RAM 112 becomes 0. Pay out the medal to the player. However, if the number of credits has not reached 50, the number of credits is incremented by 1 instead of discharging medals one by one (step S501).

  Next, it is determined whether or not the current gaming state is a regular bonus (including those provided during the big bonus) based on whether or not the regular bonus flag is set in the RAM 112 (step S502). If the current gaming state is not a regular bonus, the process proceeds to step S507. If the current gaming state is a regular bonus, the number of games and winnings in the regular bonus are counted using the counter of the RAM 112 (step S503).

  As a result of the count, it is determined whether or not a regular bonus end condition has been met (step S504). If the regular bonus end condition is satisfied, the regular bonus medium flag in the RAM 112 is deleted. Also, a counter value for counting the number of games and the number of winnings in the regular bonus is initialized (step S505). Further, the HIT lamp 54 is turned off, and the output of the regular bonus medium signal from the external output board 105 is stopped (step S506). Then, the process proceeds to step S507. Even when the regular bonus is not terminated, the process proceeds to step S507.

  In step S507, it is determined whether or not the current gaming state is a big bonus depending on whether or not the big bonus flag is set in the RAM 112. If the current gaming state is not a big bonus, the process proceeds directly to step S513. If the current gaming state is a big bonus, if the HIT lamp 54 is turned off, it is turned on. Thereby, even if only the regular bonus in the big bonus is completed and the HIT lamp 54 is turned off in step S506, the player can recognize that the HIT lamp 54 is continuously lit. If the HIT lamp 54 is in the lit state, the lit state is only maintained (step S508).

  Next, the number of payout medals in the big bonus is counted using the counter of the RAM 112 (step S509). The number of payout medals counted here exceeds the number of big bonus ends set in the RAM 112, and it is determined whether or not the big end condition is satisfied (step S510). If the big bonus end condition is not satisfied, the process proceeds to step S513.

  If the big bonus end condition is satisfied, the big bonus medium flag in the RAM 112 is deleted. If the regular bonus medium flag is set, it is also deleted. Also, a counter value for counting the number of payout medals in the big bonus is initialized. Since it may be a regular bonus in the big bonus, the value of the counter for counting the number of games and the number of winnings in the regular bonus is initialized (step S511). Further, the HIT lamp 54 is turned off and the output of the big bonus medium signal from the external output board 105 is stopped (step S512). Then, the process proceeds to step S513.

  In step S513, based on the setting status of the big bonus medium flag and the regular bonus medium flag, a state command indicating the current gaming state (the gaming state applied in the next game, here, the big bonus) is generated. To do. Then, the generated state command is transmitted to the effect control board 102.

  Further, if a small role winning flag, a replay winning flag, and a JACIN winning flag are set in the RAM 112, these are deleted. The regular bonus winning flag, the big bonus (1) winning flag, and the big bonus (2) winning flag are not deleted from the RAM 112 unless they have won the corresponding role in the game, and are carried over to the next game (step S514). . Further, here, the operation of the single BET button 14 and the MAX BET button 15 is also effective. Then, the payout process is ended, and the process returns to the flowchart of FIG. When returning to the flowchart of FIG. 12, the processing for one game is terminated as it is.

  In the repetition of the game as described above, the CPU 111 of the game control board 101 shifts the game state between the normal game state, RT, regular bonus, and big 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 based on the command received from the game control board 101. Hereinafter, processing executed by the CPU 121 of the effect control board 102 to perform various effects (particularly, display of virtual reels on the liquid crystal display 4) will be described.

  FIG. 18 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 S601). Until any command is received, the process of step S601 is repeated. When any command is received from the game control board 101, it is determined what kind of the received command is (step S602).

  If the type of the received command is the winning status notification command transmitted in step S112, 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 shown. Information is cleared (step S603). Further, the setting status of the winning flag indicated by the received winning status notification command is stored in a predetermined area of the RAM 122 (step S604).

  Next, a random number for selecting a symbol arrangement is extracted by a software random number function, and the virtual reel arrangement of the liquid crystal display 4 is determined based on the extracted random number value, the game state of the current game, and the winning status of each combination. Is determined (step S605). After that, the change of the symbol is started in each virtual reel of the liquid crystal display 4 (step S606), and the period from the start of the change of the symbol in the virtual reel until the operation of the stop buttons 12L, 12C, 12R becomes valid. Then, the array of each virtual reel that is changing is replaced with the array determined in step S605 (step S607). This arrangement is changed when the virtually rotating virtual reels do not appear on the display surface of the liquid crystal display 4 (the symbols appearing on the display surface at the start of replacement are slightly delayed in replacement). It becomes difficult for the player to notice the replacement of the arrangement. Then, the process returns to step S601.

  If the type of the received command is the reel stop command transmitted in step S306, S311 or S316, information indicating the symbol derived to the reels 3L, 3C, 3R indicated by the reel stop command is stored in the RAM 122 in advance. (Step S608).

  Next, it is determined whether or not the reel stop command received this time indicates a stop of the third reel (step S609). If the winning of the third reel is not indicated, it is determined whether the regular bonus, the big bonus (1) or the big bonus (2) and the bell, cherry or replay are won in duplicate (step S610).

  If the winning combination is duplicated, the variation of the symbols on the virtual reel corresponding to the reel stop command received this time is stopped so that the symbol of the winning combination double-temperes on the effective line of the virtual reel. For example, when the big bonus (1) or the big bonus (2) and the bell are won, the big bonus + bell arrangement is selected, but the left and right virtual reels 4L ′, 4R are selected. “7” is stopped at the upper stage for “′”, and “7” is stopped at the upper or middle stage for the virtual reel 4C ′ (step S611). Then, the process returns to step S601.

  Reel received this time so that the symbol of the winning combination will be tempered on one of the active lines of the virtual reel if it is not won in duplicate (including the case where no winning combination has been won) Stops the variation of symbols on the virtual reel corresponding to the stop command. Here, if the reel stop command received this time indicates the stop of the first reel, the symbol corresponding to the winning combination may be stopped at any of the upper, middle and lower stages. If no winning combination has been won, a symbol of any combination may or may not be tempered on the active line (step S612). Then, the process returns to step S601.

  If the reel stop command received this time indicates a stop of the third reel, a symbol corresponding to the symbol derived to the variable display device 2 is derived to the virtual reel. For example, if the big bonus (1) or the big bonus (2) and the bell are won, the “7” and the “bell” are double tempered until the third reel is stopped. Here, when the big bonus (1) or the big bonus (2) is won by the symbol derived to the variable display device 2, “7” is stopped on the active line where “7” is already tempered. . When winning the bell, the “bell” is stopped on the active line where the “bell” has already been tempered (step S613). Then, the process returns to step S601.

  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 S616). Thereafter, the process returns to step S601.

  As described above, in the slot machine 1 according to this embodiment, the result of each game in the slot machine 1 is indicated by the display mode derived to the variable display device 2 composed of the reels 3L, 3C, 3R. It is also shown 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, so that the liquid crystal display 4 can be easily viewed without displaying the variable display device 2 by displaying a virtual reel. become.

  The rotation of the reels 3L, 3C, and 3R constituting the variable display device 2 is stopped within a maximum stop delay time of 190 milliseconds from the operation of the stop buttons 12L, 12C, and 12R. Variations in symbols on the virtual reel are also stopped within the same maximum stop delay time. Here, when the big bonus (1) or the big bonus (2) is won, the arrangement of symbols on the virtual reels is changed to an arrangement other than the standard arrangement, that is, an arrangement capable of stopping “7” at an arbitrary position. . Even when the regular bonus is won, the arrangement is changed so that “BAR” can be stopped at an arbitrary position.

  For this reason, when the display mode of the big bonus (1) or the big bonus (2) is derived to the variable display device 2 by the operation timing of the stop buttons 12L, 12C, 12R, or when the display mode of the regular bonus is derived Therefore, the display mode of the big bonus or the regular bonus can always be derived to the virtual reel within the range of the maximum stop delay time of 190 milliseconds, and the player may feel uncomfortable in order to derive these display modes to the virtual reel. Absent. In addition, the replacement of the virtual reel symbol arrangement is performed sequentially from the symbols not appearing on the display surface of the liquid crystal display 4 after the virtual reel starts virtual rotation. So that no one feels uncomfortable.

  On the other hand, when neither the regular bonus nor the big bonus (1) or the big bonus (2) is won, the standard arrangement is used as the arrangement of the virtual reel symbols. Since the standard arrangement is used in the first place when neither the regular bonus nor the big bonus (1) or the big bonus (2) can be won, the big bonus is always in the range of the maximum stop delay time of 190 milliseconds. Alternatively, it is not necessary to derive the display mode of the regular bonus to the virtual reel, and it is not necessary to arrange many of the same type of “7” and “BAR” on one virtual reel. For this reason, for players who are familiar with the general symbol arrangement on reels of variable display devices, where the number of bonus symbols of the same type is limited so that they may be missed due to the need for technical intervention As a result, it is possible to avoid feeling as uncomfortable as possible in the arrangement of symbols on the virtual reel.

  Further, for example, in the big bonus + bell arrangement, “bell” is arranged two lower than “7” for the left and right virtual reels 4L ′ and 4R ′, and “7” is assigned to the inner virtual reel 4C ′. A “bell” is arranged one level below. For this reason, “7” and “Bell” can be double-tempered when up to the second reel is stopped. Here, when the big bonus (1) winning flag or the big bonus (2) winning flag is carried over and the bell is won, the big bonus (1) or big bonus is selected according to the operation timing of the stop buttons 12L, 12C, 12R. There is a time when winning the bonus (2) and a time when winning the bell.

  With such an arrangement, when the big bonus (1) winning flag or the big bonus (2) winning flag is carried over and the bell is won, the virtual reels are “7” and “Bell” until the second reel is stopped. Can be double-tempered, so that when the third reel is stopped, either the big bonus (1) or the big bonus (2) is won by the display result of the variable display device 2 or the bell is won. The display mode corresponding to the winning combination can always be derived to the virtual reel of the liquid crystal display 4 without causing the player to feel uncomfortable within the range of the maximum stop delay time of 190 milliseconds.

  Further, in the arrangement of the virtual reels other than the standard arrangement, “cherry” is arranged one or two above “7” for the left virtual reel 4L ′. Whether the player wins the Big Bonus (1) or Big Bonus (2) or wins the Cherry, the player feels uncomfortable within the maximum stop delay time of 190 milliseconds. Instead, the display mode corresponding to the winning combination can always be derived to the virtual reel of the liquid crystal display 4. This is the same for any arrangement selected when the big bonus (1), the big bonus (2) or the regular bonus and the bell, cherry or replay are selected and won.

  Furthermore, when the game state is normal or RT, an array other than the standard array is selected at a predetermined ratio even if any of the big bonus (1), the big bonus (2), and the regular bonus is not won. It is supposed to be. For this reason, even when the big bonus (1), the big bonus (2) and the regular bonus are not actually won, the big bonus (1), big The player can be expected to win the bonus (2) or the regular bonus, and the interest of the game can be improved.

  By the way, the playability of a slot machine is not just playing a game, but the player earns medals based on the game results. It can be said that. In this slot machine 1, there are bells and cherries as types of small roles, but they are determined as types of winning combinations in any gaming state. In this way, by defining the basic small combination as a winning combination regardless of the gaming state, the gameability becomes easy for the player to understand.

  The big bonus ends when the number of medals paid out exceeds 165 or 345 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 “Bell-Cherry-Cherry” and is not used as a display mode for 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. Since the active line is a combination of either the upper or lower stage, it is not missed when the small part of the bell is won. In particular, the bells in the regular bonus will be won with a very high probability of approximately 1 / 1.03, but this will not be missed, so the player will effectively hold on to the regular bonus. It becomes unnecessary, and it becomes possible to advance the game easily.

  As described above, the types of winning combinations that are subject to internal lottery for each gaming state are registered in the winning combination table by gaming state, but the number of judgment values that determine the winning probability of each combination is referred to from the determining table. Stored in the address. In the role table, the number of medals to be paid out when winning for each role is also registered.

  In the role-specific table, the number of payouts is registered according to the number of bets, and when a cherry win is generated, the number of payouts is set according to the number of bets. Here, the number of bets in the regular bonus is fixed at 1, but the number of bets in the gaming state other than the regular bonus is fixed at 3. As a result, it is possible to pay out an appropriate number of medals according to the gaming state simply by acquiring the number of determination values according to the number of bets. In addition, since it is not necessary to determine the gaming state when setting the number of payouts, the processing steps in the winning determination process are simplified. Moreover, the number of wagers corresponding to the regular bonus is higher than the number of wagers of 3, and the number of medals to be paid out at the time of winning a cherry is higher. Interest can be improved.

  For the bells and cherries defined as winning prizes in any gaming state in the role-specific table, the storage address of the determination value number is registered for each bet number, and the determination value number is acquired according to the bet number. (However, in the case of cherry, the same number of judgment values is acquired as a result). Here, the number of bets in the regular bonus is fixed at 1, but the number of bets in the gaming state other than the regular bonus is fixed at 3. As a result, it is possible to perform the internal lottery of the bell and the cherry with the winning probability corresponding to the gaming state only by acquiring the determination value number according to the betting number. In addition, since it is not necessary to determine the gaming state when acquiring the determination value number, the processing steps in the internal lottery are simplified. Moreover, the betting number 1 corresponding to the regular bonus has a higher probability of winning the bell than when the betting number is 3, so that the player's expectation in the regular bonus is further increased and the interest of the game is improved. Can do.

  In addition, the storage address of the judgment value number of each combination registered in the combination table may differ depending on the set value, but the winning probability is the same regardless of the set value. For the winning combination, 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.

  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, since the internal lottery is performed by sequentially adding the number of determination values corresponding to each combination to the value of the random number for the internal lottery, as shown in FIGS. The random number value for internal lottery with the winning combination will be hardened. 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.

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

  In the above embodiment, when the big bonus (1), the big bonus (2), or the regular bonus is won, the virtual reel arrangement is standard before detecting the operation of the stop buttons 12L, 12C, 12R. It was supposed to be changed to an array other than the array. As a result, “7” or “BAR” can be stopped on the effective line of the virtual reel within the range of the maximum stop delay time of 190 milliseconds.

  On the other hand, as the arrangement of the virtual reels, only the standard arrangement may be applied regardless of the gaming state or the winning situation, and the symbols may be replaced as necessary. For example, when the big bonus (1) or the big bonus (2) is won and the left reel 3L as the first reel stops ("red 7" can always be stopped at the upper or lower level), it stops. Assume that symbols 0 to 13 in FIG. 10 are positioned in the lower stage of the virtual reel 4L at the operation timing of the button 12L. In this case, any symbol within 7 frames including the symbol positioned at the lower level of the virtual reel 4L (for example, when the number 0 is positioned at the lower level, symbols 0 to 6 are replaced with “7”). It is good.

  Further, for example, when the middle and right virtual reels 4C and 4R are stopped and “7” is tempered on the lower effective line, the symbol 0 is displayed at the operation timing of the stop button 12L. If it is located at the lower stage of 4L, the symbols from No. 4 to No. 4 for 5 frames from the position of the lower stage, which is the effective line for “7”, can be used as the symbols to be replaced. When the display mode of the regular bonus is derived, the symbols other than “BAR” can be replaced with “BAR” in the same manner.

  In this way, the symbol that can be stopped within the range of the maximum stop delay time from the operation timing of the stop buttons 12L, 12C, 12R to the position where it is necessary to stop “7” in order to derive the display mode of the big bonus. If “7” is not included in the symbol, the other symbols can be replaced with “7” at this time (the same applies when the display mode of regular baud is derived). As a result, since “7” can be stopped at any position in any virtual reel, the display mode of the big bonus or the regular bonus is always derived to the virtual reel within the maximum stop delay time of 190 milliseconds. It will be possible.

  On the other hand, except for the replacement of the symbols to “7” or “BAR” in these cases, the symbols are displayed in a variable manner according to the standard arrangement on the virtual reel. For players who are familiar with the general symbol arrangement on variable display device reels, where the number of bonus symbols of the same type is limited so that they may be missed, the symbol arrangement on the virtual reel You will not feel as uncomfortable as possible.

  For example, for the left reel 3L that is stopped as the first reel, the symbol that is replaced with “7” when the stop button 12L is operated at the above timing is the virtual reel 4L at the operation timing of the stop button 12L. It is preferable to select from symbols 3 to 6 which are not displayed above. For the left reel 3L that is stopped as the third reel when “7” is tempered in the lower row, the symbol that is replaced with “7” when the stop button 12L is operated at the above timing is the symbol of the stop button 12L. It is preferable to select from the 3rd and 4th symbols not displayed on the virtual reel 4L at the operation timing. In this case, the symbols that have not been displayed on the liquid crystal display 4 are replaced, so that the player does not feel a sense of discomfort due to the replacement of the symbols on the original arrangement. become.

  However, in these cases, the symbol to be replaced with “7” may be selected from symbols 0 to 2 displayed on the virtual reel 7L at the operation timing of the stop button 12L. In this case, the visual recognition state of the symbol may be lowered before and after the symbol replacement (for example, dark display, mosaic display, blur display, etc. are performed). By reducing the visual recognition state of the symbol before and after the replacement in this way, it is possible to minimize the uncomfortable feeling associated with the symbol replacement.

  In addition, for example, when the big bonus (1) or the big bonus (2) and the bell are won, the symbols are replaced so that “7” and “Bell” are double tempered until the second reel is stopped. It can be. In this case, even when winning the regular bonus, the big bonus (1) or the big bonus (2) according to the display result of the variable display device 2 when the third reel is stopped, The display mode corresponding to the winning combination can be always derived to the virtual reel of the liquid crystal display 4 without causing the player to feel uncomfortable within the range of the maximum stop delay time of 190 milliseconds.

  Furthermore, when the game state is normal or RT, symbols are replaced at a predetermined rate even when neither the big bonus (1), the big bonus (2) or the regular bonus is won. be able to. In this case, the symbol replacement may be performed for all or part of the three virtual reels 4L, 4C, and 4R. By such replacement, even if the player has not actually won any of the big bonus (1), the big bonus (2), or the regular bonus, the player will win the big bonus (2) or the regular bonus. Can be expected to improve the fun of the game.

  By the way, when the symbol is replaced with “7” or “BAR” as described above, depending on the selection of the symbol to be replaced and the method of replacement, the symbol replacement may be a game. It doesn't make you feel uncomfortable. However, if the relationship with the symbols in the vicinity of the replaced symbols is seen, the player can understand the replacement of the symbols, which may cause the player to feel uncomfortable. When a plurality of symbols are displayed on one virtual reel as in the above-described embodiment, only the relationship of symbols appearing fluctuating between the operation of the stop button 12L, 12C, 12R and the stop of the virtual reel. Instead, the replacement may be found only by looking at the relationship between the stopped three symbols.

  Therefore, when a regular bonus, a big bonus (1), or a big bonus (2) with a possibility of symbol replacement is selected, for example, any one of the symbols displayed so as to be easily visible on the virtual reel is displayed. Only on one active line (for example, the effective line in the middle), so that the player cannot visually recognize the symbol outside the effective line (or it is difficult to visually recognize by dark display, mosaic display, blur display, etc.) May be. The timing at which this is performed can be the same as the timing at which the arrangement is replaced in the above embodiment.

  When the symbol on the effective line in the middle row is selected as a symbol that can be easily visually recognized, when the Big Bonus display mode is to be derived, the middle row is displayed when the stop button 12L corresponding to the left virtual reel 4L is operated. It is determined whether or not “7” is present in the symbol displayed in the symbol and the symbol of the four frames in the drawing range from the symbol. If “7” is present, it may be stopped and displayed as an easily visually recognizable symbol in the middle stage. If there is no “7”, any symbol in the four frames in the pull-in range may be replaced with “7”, and this may be stopped and displayed as an easily visible symbol in the middle stage.

  In this way, by limiting the number of symbols that can be easily viewed on each virtual reel and then replacing the symbols, the relationship between the symbols stopped so that they can be easily viewed and the surrounding symbols is It can only be seen while appearing fluctuating between the operation of the stop buttons 12L, 12C and 12R and the stop of the virtual reel. The visibility of such a fluctuating symbol is very low compared to a symbol that is stopped. Therefore, it is possible to prevent the player from noticing the replacement of symbols, and to prevent the player from feeling uncomfortable.

  Note that the number of symbols that can be easily visually recognized on the virtual reel as described above is not limited to when the regular bonus, the big bonus (1), or the big bonus (2) is won. Even when not winning, it may be performed at a predetermined rate. As a result, the player is expected to win the big bonus (2) or the regular bonus even when the big bonus (1), the big bonus (2), or the regular bonus is not actually won. Can improve the interests of the game.

  By the way, when only the regular bonus, the big bonus (1) or the big bonus (2) are won, whether or not to win these roles according to the operation timing of the stop buttons 12L, 12C, 12R Only. For this reason, if “BAR”, “Red 7” or “White 7” is displayed on the variable display device 2 at the stage where the second reel is stopped, “BAR” and “7” are also displayed on the virtual reel. However, if no winning is achieved due to the stop of the third reel, it is only necessary to derive other than “BAR” or “7” for the corresponding virtual reel. Therefore, there is no problem just by replacing the symbols as described above.

  However, when the regular bonus, big bonus (1) or big bonus (2) and other roles, especially small roles that do not know which will ultimately be won, are selected, the stage where the first reel is stopped If “7” or “BAR” is derived to the virtual reel or if the “7” or “BAR” is tempered when the second reel stops, the virtual reel will eventually be awarded to the small role. In some cases, the display mode of the small role cannot be derived.

  Therefore, for example, when the regular bonus winning flag is carried over in the game when the bell is won and the bell winning flag is also set, there is a possibility of winning the regular bonus depending on the display mode of the variable display device 2. As long as the second reel is stopped, the combined symbol of “BAR” and “Bell” may be stopped as a middle symbol of the virtual reel that is easily visible. Similarly, when winning the bell in the game when the big bonus (1) winning flag or the big bonus (2) winning flag is carried over, the combined symbols of “7” and “Bell” are virtually displayed until the second reel stops. It can be stopped at the middle of the reel.

  The arrangement of symbols on each virtual reel may or may not include such a composite symbol in advance. When the first and second reels are stopped, the composite symbol is not displayed in the middle stage of the corresponding virtual reel at the timing when the stop buttons 12L, 12C, and 12R are operated, and the four-frame drawing range is also displayed from there. If a composite symbol is not included (including a case where a composite symbol is not included in the original array), replace any symbol within the 4-frame pull-in range with the composite symbol, and then the virtual reel The composite symbol can be derived in the middle stage.

  By deriving such a composite symbol, “BAR” or “7” and “Bell” can be double-tempered to the virtual reel when the second reel is stopped, so that it can be changed by stopping the third reel. Whether the regular bonus, the big bonus (1) or the big bonus (2) is won or the small role is won according to the display result of the display device 2, the display mode corresponding to the winning role is always displayed on the liquid crystal display. 4 virtual reels can be derived.

  In the above embodiment, the maximum stop delay time for the reels 3L, 3C, 3R constituting the variable display device 2 and the maximum stop delay time for the virtual reel of the liquid crystal display 4 are the same at 190 milliseconds, Moreover, both rotation speed was also the same at 80 rpm, and also the number of symbols of both was the same at 21 frames. For this reason, the pull-in range from the symbols displayed when the stop buttons 12L, 12C, and 12R are operated is four frames. However, for example, even if the rotation speeds are the same, the variable display device 2 is configured as long as the maximum stop delay time for the virtual reel of the liquid crystal display 4 is set within a predetermined time range. The maximum stop delay time for the reels 3L, 3C, and 3R to be played may be different, and the number of frames to be drawn may be different regardless of whether the maximum stop delay time is the same or different. .

  Here, when the maximum stop delay time for the virtual reel is slightly longer and there is a drawing range of 5 frames from the symbols displayed when the stop buttons 12L, 12C, and 12R are operated, the virtual reels other than the standard arrangement are used. Place “7” (arrangement when winning big bonus (1) or big bonus (2)) or “BAR” (arrangement when winning regular bonus) within an interval of 6 frames It should be. The positions of “bell”, “cherry”, and “JAC” can be determined at the position of “7” or “BAR” in the sequence. Furthermore, even when the rotational speeds are different from each other, the arrangement of symbols on the virtual reel can be determined according to the pull-in range corresponding to the maximum stop delay time.

  In the above embodiment, when the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is carried over, and when a bell or cherry is further won, it is more regular than the bell or cherry. The bonus, the big bonus (1) or the big bonus (2) is derived with priority, but this may be reversed.

  If Bell or Cherry is derived in preference to Regular Bonus, Big Bonus (1) or Big Bonus (2), the first after winning Big Bonus (1) or Big Bonus (2) Even if it is controlled that the display mode of the big bonus is derived to the virtual reel when the small role is won, the display mode of the big bonus can be derived to the virtual reel upon the first small role winning. .

  In the above embodiment, a virtual reel is displayed on the liquid crystal display 4 regardless of the progress of the game, and the effect symbols are displayed in a variable manner in accordance with the variations of the symbols on the variable display device 2. It was. Of course, depending on the progress of the game, an effect other than the variable display of the effect symbol by the virtual reel may be performed on the liquid crystal display 4. For example, when the number of digested games or the number of paid-out medals in the big bonus exceeds a predetermined number, it is possible to produce an effect with an image that has nothing to do with the virtual reel.

  In the above embodiment, there are two types of big bonuses with different upper limit numbers of payout medals. The difference is only known whether the big bonus (1) is won or the big bonus (2) is won. In the case of playing the game while looking only at the virtual reel of the liquid crystal display 4, the player did not know which big bonus it was. On the other hand, the display mode of the big bonus on the virtual reel when winning the big bonus (1) and when winning the big bonus (2) may be different from each other.

  In addition, when the number of payout medals in the big bonus exceeds 165, it can be shown by the effect which big bonus it is. Here, in order to give the player a sense of expectation that the upper limit is 360 big bonuses, no matter what the big bonus end number is set, when the number of payout medals exceeds 165 Freeze control (control that makes it impossible to set the number of bets for the next game for a certain period after the medals are paid out), and during the freeze control period or when the freeze control ends Can be displayed on the liquid crystal display 4 to indicate to the player.

  In the above embodiment, when the big bonus (1) of “Red 7-White 7-White 7” is won, the upper limit of the big bonus is 180 (finished with a payout exceeding 165), and “Red 7- When the big bonus (2) of “Blue 7-Blue 7” was won, the maximum number of big bonuses was 360 (finished with a payout exceeding 345). However, the upper limit number of big bonuses may be determined by lottery regardless of the type (symbol) of the big bonus won. In this case, there may be one type of display mode (big bonus winning flag) for winning the big bonus. The determination of the maximum number of big bonuses can be made at an arbitrary timing from when the big bonus is won in the internal lottery until when the display mode of the big bonus is derived on the variable display device 2.

  In the above embodiment, the gaming state of the slot machine 1 includes a regular bonus and a big bonus (small role game and regular bonus) in addition to the normal gaming state. On the other hand, the maximum stop delay of one or more of RT (Replay Time), reels 3L, 3C, and 3R that makes the winning probability of replay higher than the normal gaming state without changing the winning probability of other roles In order to shorten the time (for example, 75 milliseconds (one frame slip)) and to allow a winning combination to be set regardless of the result of the internal lottery. It may further include a gaming state such as AT (Assist Time) for notifying the gaming procedure.

  Even if the transition to CT, RT, and AT is performed based on winning a corresponding role, a role added for that purpose is a special role and not a basic role. In RT, only the winning probability of replay is increased, and the composition of the combination is not changed from the normal gaming state. Even in AT, the composition of the combination is not changed but only the game procedure is notified. Even if the CT is not an object of the internal lottery, it is possible to win a small role that is the most basic character, so the basic composition of the character does not change. Therefore, even if these game states are included, the gameability can be easily understood without changing the basic role configuration.

  In the above embodiment, when the big bonus (1) is won and when the big bonus (2) is won, the gaming state is controlled to the big bonus having the same gameability except that the upper limit of the number of payout medals is different. It was supposed to be. Of course, it is also possible to control the gaming state to be controlled with different upper limit of the number of paid-out medals when the big bonus (1) is won and when the big bonus (2) is won. When winning a big bonus (2) with a large upper limit on the number of payout medals, the game state will remain the same until there are more than 165 medals paid out when the big bonus (1) is won. After controlling to the big bonus and paying out more than 165 medals, the game state may be controlled to a gaming state different from the big bonus.

  For example, a challenge bonus can be applied as a gaming state that is different in gaming characteristics from the big bonus. Like the big bonus (1) or the big bonus (2), the challenge bonus starts when a predetermined display mode (big bonus symbol) is derived on the variable display device 2. In a game with a challenge bonus, the maximum stop delay time of any one or more of reels 3L, 3C, and 3R is reduced to 75 milliseconds, and it becomes possible to win a small role regardless of the result of the internal lottery. . Then, when the number of payout medals reaches a predetermined number, the challenge bonus ends.

  Of course, even when different gaming states, such as big bonus and challenge bonus, are applied, until the number of paid-out medals reaches the upper limit of the least one, the player cannot make an apparent distinction, or It must be difficult. For example, in the challenge bonus, control is performed so that the type of small part with the largest number of payouts among multiple types of small parts is preferentially arranged. The probability of winning may be set to 0 or a value close to 0, and the probability of winning the winning combination with the largest payout number may be set to a value close to 1. The difference in the maximum stop delay time does not preclude making the apparent distinction difficult in view of the fact that the operation of the stop buttons 12L, 12C, 12R by the player cannot be perfect.

  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 determination values of a combination such as a regular bonus, a big bonus (1), and a big bonus (2) cannot exceed 255 in any game situation. . Thus, for those that do not need to set the number of determination values exceeding 255, the number of determination values may be stored using only a 1-byte area.

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

  In the above embodiment, in the normal gaming state, the game can be started only by setting 3 as the bet number. On the other hand, even in a normal gaming state, the game can be started by setting 1 as the number of bets, and can be started by setting 2 as the number of bets. May be.

  In the normal gaming state, when 1 or 2 is set as the bet number, the winning probability of the small role in the internal lottery is lower than when 3 is set as the bet number, and the payout when winning the small role The number of medals can be increased. Further, in a slot machine that can set any one, two, or three bets as the number of bets in the normal gaming state and the small bonus game in the big bonus, the number of determination values is stored in common for all of the setting values 1 to 6. There may be a combination that is stored in common for all of the bets 1 to 3 as well as a combination that is stored. 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, the number of determination values acquired in accordance with the set value or the like is sequentially added to the random number value for internal lottery, but from the value of random number for internal lottery that acquired the acquired determination value number Subtraction may be performed sequentially, and the result of subtraction may be used as a new random value for internal lottery. When the number of determination values is subtracted from the random number value for internal lottery, the 15th and 14th bits of the random number for internal lottery are set to “0”, and the subtraction result overflows (here, the subtraction result is negative) It can be determined whether or not

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

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

  FIG. 19 is an explanatory diagram of a first modification of the process (step S102) until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. Also in the first modification, the random number extracted from the random number generation circuit 115 is stored in the 16-bit general-purpose register 111GR included in the CPU 111.

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

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

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

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

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

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

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

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

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

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

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

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

  FIG. 21 is an explanatory diagram of a third modification of the process (step S102) until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. In this example, the signal wirings connecting the random number generation circuit 115 and the sampling circuit 116 are connected so that the order of bits is reversed for each of the upper 8 bits and the lower 8 bits. Accordingly, the data latched by the sampling circuit 116 is reverse in the order of bit arrangement for the upper 8 bits and the lower 8 bits with respect to the data signal output by the random number generation circuit 115.

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

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

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

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

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

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

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

  In the third modification, 11h is subtracted from the upper area data before the final exclusive OR operation (FIG. 21 (i)) of the upper area data and the lower area data (FIG. 21). 21 (e)), rotate 1 bit lower (FIG. 21 (f)), perform exclusive OR operation with the lower area data (FIG. 21 (g)), and process the upper area data in advance. However, not all of these are necessarily required, and any one or two of them can be applied, and there is no need to process the data in the upper area before the final exclusive OR operation. Good. The upper area data at this time may be the final upper byte data in the random number for internal lottery. The order in which the processes of FIGS. 21E to 21F are performed can be changed to an arbitrary order.

  Further, the value to be subtracted in FIG. 21 (e) is not limited to 11h, and any value other than 00h can be added or subtracted, and the rotation in FIG. 21 (f) is limited to 1 bit in the lower order. It can be rotated up or down by any number of bits up to 7 bits. The data in the lower region subjected to the exclusive OR operation in FIG. 21 (g) may be obtained by performing a predetermined operation on the data first input to the lower region from the random number generation circuit 115. As a calculation performed on the data in the upper area, a calculation by an arithmetic expression other than this can be applied. Furthermore, the data in the save area that is exclusively ORed with respect to the data in the upper area in FIG. 21 (i) may be data that is first input to the lower area from the random number generation circuit 115. Data obtained by performing a predetermined calculation different from (e) to (g) may be used.

  Further, the final lower byte data in the random numbers for internal lottery may be the data that is first input from the random number generation circuit 115 to the lower area as it is. The data in the save area after adding 78h in FIG. 21 (h) may be used as the final lower byte data in the random number for internal lottery. Alternatively, 78h may be added to the data of the result of the exclusive OR operation stored in the lower area in FIG. 21 (g) to obtain the final lower byte data. Furthermore, as a calculation to be performed on the data in the lower area, a calculation based on another calculation formula may be applied, and the calculation result may be the final lower byte data in the random number for internal lottery.

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

  On the other hand, when the instruction set of the CPU 111 is the one-address method, for example, when subtraction as shown in FIG. 21E is performed, the data stored in the upper area of the RAM 112 is first stored in an accumulator (general-purpose register). ), 11h is subtracted from the accumulator data, and the subtraction result data is stored again in the accumulator. Here, when the data stored in the upper area of the RAM 112 is loaded into the accumulator, the accumulator effectively acts as the upper area. Here, the accumulator still operates on the data in the upper area. It is not necessary to store the data in the upper area of the RAM 112 yet.

  In FIG. 21 (f), the accumulator data in which the result of the subtraction in FIG. 21 (e) is stored is rotated one bit lower, and the result data is stored again in the accumulator. In FIG. 21G, an exclusive OR operation is performed on the data stored in the lower area of the RAM 112 with respect to the accumulator data in which the result of the operation of FIG. Is stored in the accumulator. Since the accumulator is still functioning as the upper area of the RAM 112 at this point, the accumulator data may be stored in the lower area of the RAM 112 in FIG. 21 (g) → (j).

  Furthermore, in FIG. 21 (h), the data in the save area of the RAM 112 is loaded into the accumulator. However, the accumulator functions as the save area here, and 11h may be added to the accumulator data and stored in the accumulator. In FIG. 21 (i), the data of the accumulator is exclusive ORed with the data in the upper area of the RAM 112 for each bit, and the result is stored in the accumulator, but the result of the exclusive OR operation is stored. After that, the accumulator again acts as the upper region.

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

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

  In the RAM 112, the same upper area and lower area are used both for the area for storing the 2n-bit numerical data fetched from the sampling circuit 116 and for the area for storing the finally generated random numbers for internal lottery. However, separate areas may be used. For example, if a 2-byte random number area that stores the finally generated random numbers for internal lottery is provided separately from the upper and lower areas, the upper area data is stored in the lower bytes of the random area. Then, the result data of the exclusive OR operation of FIG. 21 (i) may be stored in the upper byte of the random number area.

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

  The method for generating random numbers for internal lottery in the third modification can change the processes in FIGS. 21A to 21D as shown in FIGS.

  In the example of FIG. 22, the random number generated by the random number generation circuit 115 is changed in the order of bits in the upper 8 bits and the lower 8 bits as in the case of FIGS. (A) to (b). Next, the upper 8 bits of the random number taken by the sampling circuit 116 are taken into the upper area of the RAM 112 via the upper port, and the lower 8 bits are taken into the lower area of the RAM 112 via the lower port (b) to (d). Thereafter, the numerical data stored in the upper byte and the numerical data stored in the lower byte may be exchanged by software processing to obtain a random number before processing (e).

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

  In the example of FIG. 23, the connection of the wiring between the random number generation circuit 115 and the sampling circuit 116 is not reversed. First, the random numbers generated by the random number generation circuit 115 are converted into the sampling circuit 116 in the bit arrangement order as they are. (A) to (b). Next, the upper 8 bits of the random number taken by the sampling circuit 116 are taken into the upper area of the RAM 112 via the upper port, and the lower 8 bits are taken into the lower area of the RAM 112 via the lower port (b) to (d).

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

  In the example of FIG. 24, the wiring between the random number generation circuit 115 and the sampling circuit 116 is reversed between the upper byte and the lower byte, and is connected so that the bit order does not change in each byte. . Here, the random number generated by the random number generation circuit 115 is taken into the sampling circuit by switching the upper byte and the lower byte (a) to (b). Next, the upper 8 bits of the random number taken by the sampling circuit 116 are taken into the upper area of the RAM 112 via the upper port, and the lower 8 bits are taken into the lower area of the RAM 112 via the lower port (b) to (d).

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

  In the example of FIG. 25, the wiring between the random number generation circuit 115 and the sampling circuit 116 is completely connected in reverse order. Here, the sampling circuit 116 takes in the order of the random number bits generated by the random number generation circuit 115 in the reverse order (a) to (b). Then, the upper byte and lower byte of the random number fetched by the sampling circuit 116 may be fetched as they are into the upper area and lower area of the RAM 112 via the upper port and lower port as they are (b) to (d).

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

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

A slot machine that stops the rotation of the reels 3L, 3C, and 3R in a table system that stops the reels at the symbol stop position registered in the reel control table (see, for example, Japanese Patent No. 2627604) ). Here, in the reel control table, the stop position of the symbol is determined in advance, but this stop position is determined within the range of the maximum stop delay time of the reels 3L, 3C, 3R according to the gaming state. is there. That is, the symbols that are stopped by operating the stop buttons 12L, 12C, and 12R are selected within the range of the maximum stop delay time.

  The reel control table is selected in advance according to the setting state of the winning flag and the game state before the stop buttons 12L, 12C, and 12R are operated. Depending on which reel control table is selected, the reel control table is stopped. Even if the operation timings of the buttons 12L, 12C, and 12R are the same, the symbols to be stopped are different. Therefore, selecting the reel control table selects a symbol according to the setting state of the winning flag and the gaming state. Furthermore, the reel control table registers the relationship between the position of the symbol displayed when the stop button 12L, 12C, 12R is operated and the position where the symbol is to be stopped, but the stop button 12L, 12C. , 12R is selected corresponding to the symbol display position when the symbol display position is operated. Therefore, when the stop button 12L, 12C, 12R is operated, the symbol stop position is selected. It can be said that
