Description

  The present invention relates to a slot machine, and in particular, a special display mode involving a transition to a special gaming state advantageous to a player and a non-special display mode other than the special display mode are defined as a winning display mode. Related to slot machines.

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

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

  Most of the display modes for winning are determined by the combination of symbols derived on the three reels on the winning line, but in the display mode for the small role, only the symbols derived for one reel are awarded. Many slot machines have a display mode (so-called single symbol). When there is such a single symbol small combination, if the display mode of the bonus is derived, it is easy to obtain an arrangement in which the display mode of the single symbol small combination can also be derived. However, when both the bonus display mode and the small role display mode are derived, even if there is no single symbol small role, it may occur depending on the arrangement of symbols on each reel. Further, depending on the arrangement of symbols, it may happen that a plurality of types of small combination display modes are derived.

  When a plurality of types of winning display modes are derived in this way, if a player is given all the values determined for each of the derived display modes, the player is awarded with one game winning. This is not preferable from the viewpoint of suppressing the emissivity. Here, if a plurality of types of small combination display modes are derived, even if the number of medals paid out corresponding to each display mode exceeds the maximum number (15), the number of medals actually paid out It's just a matter of restricting. On the other hand, when both the bonus display mode and the small role display mode are derived, the type of value assigned to each of them is different, so it is necessary to consider a countermeasure from the viewpoint of suppressing shooting characteristics. It will be.

  Therefore, in many slot machines, when a bonus display mode is derived, an arrangement of symbols cannot be derived, and both a bonus display mode and a small role display mode are derived. Is prevented. However, in order to do so, the arrangement of the symbols is limited, and there is a possibility that the gameability may be lowered. Therefore, the arrangement of the symbols from which both the bonus display mode and the small role display mode can be derived However, there is a slot machine that prevents the display mode of the small combination from being derived when the bonus display mode is derived by the reel stop control.

  In the case of the latter type of slot machine, both the bonus display mode and the small role display mode are not derived as long as the game progress control is normally performed, but the game progress control is not performed. If an abnormality occurs, both the bonus display mode and the small role display mode may be derived. In such a case, there has been a slot machine that performs control to prohibit the progress of the game before the medals are paid out (see, for example, Patent Document 1).

JP 2006-6558 A (paragraph 0193)

  By the way, the fact that both the bonus display mode and the small role display mode are derived means that a serious abnormality such as an illegal program being used, a bug in the program, or the content of the ROM or RAM being broken. This is what happens when On the other hand, the control performed when both the bonus display mode and the small role display mode are derived in the slot machine of Patent Document 1 is simply a control for prohibiting the progress of the game.

  On the other hand, the control for simply prohibiting the progress of the game is performed even when the normal control is performed for the progress of the game, such as stopping. If the progress of the subsequent game is prohibited by the result of the game that has been normally progressed so far, it will be inconvenient if it cannot be released easily. In addition, even if the game is progressing normally, even if it is controlled to a state that is controlled (that is, the state where the progress of the game is prohibited), this alone can immediately distinguish whether a serious abnormality has occurred. It was difficult.

  According to the present invention, when a serious abnormality in which both a special display mode and a non-special display mode are derived, accurate control can be performed and the severity of the generated abnormality can be easily recognized. The purpose is to provide a slot machine.

Decide whether to allow the mode to be derived to any of the winning lines
It is characterized by that.

  In the slot machine according to the first and second aspects, as a winning display mode that can be derived to the variable display device, there are a special display mode involving transition to a special gaming state and a non-special display mode other than the special display mode. It has been established. The special display mode and the non-special display mode are different in the type of value given to the player by the derivation, so as long as the progress of the game is normally controlled, the derivation control means has the special display mode. The variation display of the identification information is controlled so that both the mode and the non-special display mode are not derived.

However, depending on the arrangement of the identification information in the variable display device, it may happen that both the special display mode and the non-special display mode are derived when an abnormality occurs in the control of the derivation control means. This can occur only when a serious abnormality that was not originally planned as a control of the progress of the game occurs, and in particular, there is often an abnormality in the data stored in the data storage means. . When an abnormality occurs in the data stored in the data storage means, for example, there is a strong possibility that the setting value is rewritten to an unauthorized stage by an unauthorized operation.

Here, in the slot machine according to the first aspect, when both the special display mode and the non-special display mode are derived in this way, the progress of the game is not simply disabled. The state in which the data is disabled cannot be canceled unless the data stored in the data storage means is initialized because the initialization condition is satisfied by performing the power-on operation while performing a special operation. On the other hand, in the slot machine according to the second aspect, when both the special display mode and the non-special display mode are derived in this way, the progress of the game is not simply disabled. In a state in which the setting is disabled, a new setting value is set based on the operation of a predetermined setting operation means (setting switch 91) by satisfying a setting value setting permission condition by performing a power-on operation while performing a specific operation. It is assumed that it is not canceled unless it is set.
In this way, when both the special display mode and the non-special display mode are derived, the progress of the game is disabled, so that accurate control can be performed for the occurrence of such a serious abnormality. In addition, since it is assumed that the game cannot be canceled easily as in the case where the progress of the game is controlled to be impossible in the originally scheduled game (for example, stopping), it is easily recognized that a serious abnormality has occurred. Will be able to.

  Here, the set value data stored in the data storage means is read out, and it is determined whether or not the set value data is appropriate. If the set value data is not appropriate, it means that a serious abnormality has occurred that makes it impossible for the game to proceed properly, so that the game is disabled. Here, since the state where the progress of the game is disabled cannot be easily released, it is possible to easily recognize that a serious abnormality has occurred.
  Further, when the slot machine is powered on, it is determined whether or not the data stored in the data storage means matches the data before the power is shut off. If the stored data does not match the data before the power is shut off, it means that a serious abnormality has occurred that makes it impossible for the game to proceed properly, so that the game is disabled. Here, since the state where the progress of the game is disabled cannot be easily released, it is possible to easily recognize that a serious abnormality has occurred.
  In these cases, the state where the progress of the game is disabled based on the fact that the set value data stored in the data storage means is not appropriate will not be canceled unless a new set value is set. For this reason, an appropriate set value is not arbitrarily set on the machine side, and it is ensured that the game is played based on the newly set value, so that the fairness of the game can be achieved.

  In the slot machine according to the first and second aspects, the non-special display mode may include at least a small role display mode (watermelon, bell, cherry) accompanied by the game value. In the non-special display mode, in addition to the small role display mode, a re-game display mode (replay) accompanied by a re-game that can be used in the next game without using the game value for setting the number of bets. Can also be included.

In the slot machine according to the second aspect,
The set value setting means may include a data initialization means for initializing the data stored in said data storage means when the set value setting permission condition is satisfied (step S 111), the new by the set value setting operation The data indicating the set value set in is stored in the data storage means (step S208),
The disabling cancellation means initializes the data stored in the data storage means by the data initialization means in a state where the progress of the game is disabled by the derivation abnormality time disabling means, and the setting that the set value is newly set as a condition by the value setting means cancels the state of progress are disabled in the game, it is possible to allow the progress of the game (Figure 10: a game control process ( To FIG. 13)).

The slot machine according to the second aspect is also:
In addition to the specific operation, an initialization condition that is satisfied only when a power-on operation (setting key switch 92 and data clear switch 95 are activated in an ON state) is performed while performing a predetermined special operation. Further comprising data initialization means (step S111) for initializing the data stored in the data storage means when established together with the permission condition ;
The disabling cancellation means initializes the data stored in the data storage means by the data initialization means in a state where the progress of the game is disabled by the derivation abnormality time disabling means, and the setting that the set value is newly set as a condition by the value setting means cancels the state of progress are disabled in the game, it is possible to allow the progress of the game (Figure 10: a game control process ( To FIG. 13)).

When both the special display mode and the non-special display mode are derived, there is a strong possibility that the data stored in the data storage means has an abnormality, but the data in which the abnormality has occurred is not necessarily the set value data. Not limited to. Therefore, in a state where both the special display mode and the non-special display mode are derived and the progress of the game is disabled, the power storage operation is performed while performing the special operation to establish the initialization condition in the data storage means. It is assumed that it is not canceled unless the stored data is initialized. Thereby, it is possible to make it difficult to cause inconvenience that both the special display mode and the non-special display mode are derived again in the game performed after the data storage unit is stored.

Further, when the data stored in the data storage unit is to be initialized when the set value setting permission condition is satisfied as in the former case, the initialization and the set value of the data stored in the data storage unit are performed. Can be easily performed by common operations. On the other hand, in the case of initializing the data stored in the data storage means when the initialization condition is satisfied together with the set value setting permission condition by performing a special operation in addition to the specific operation as in the latter case, merely set value to change before and after the progress of the game is disabled when it is power-on operation is while certain operations only, since such gaming state is not changed, the change of the set value It can be made difficult for the player to detect.

The slot machine according to the first and second aspects is as follows.
When it is determined by the winning determination means that the small combination display mode of the non-special display modes is derived to any winning line, the number of games corresponding to the derived small combination display mode Valuable value provision means (step S1002) for imparting utility value to the player may be further provided. In this case,
The derivation abnormality disabling unit determines that the special display mode is derived to any one winning line and the non-special display mode is derived to another winning line by the winning determination unit. The game value can be disabled before the player is given a number of game values corresponding to the derived small role display mode by the valuable value granting means (step). S405 → S406).

  In this case, in spite of a serious abnormality that both the special display mode and the small role display mode are derived, the player is informed based on the small role display mode derived to the variable display device. The inconvenience that a game value is given can be prevented.

The slot machine according to the first and second aspects is as follows.
When it is determined by the winning determination means that the special display mode is derived to any one winning line and the non-special display mode is derived to another one winning line, an error indicating that fact is displayed. An erroneous winning signal output means (step S907) for outputting a winning signal (illegal winning signal) to the outside of the slot machine may be further provided.

  In this case, for example, the special display mode and the non-display mode are not displayed by turning on a call lamp installed on the amusement island of the amusement store by an erroneous input signal output to the outside or by monitoring with a central management computer of the amusement store. The occurrence of a serious abnormality that the special display mode is derived at the same time can be easily recognized by the game store.

In the slot machine according to the first and second aspects,
When the winning determination means determines that a winning display mode is derived in the winning line, is the derived winning display mode a winning display mode allowed to be derived by the pre-decision means? Permissible derivation determining means for determining whether or not may be included. In this case,
The derivation abnormality disabling unit is configured to determine that the winning display mode derived to the winning line by the allowable derivation determining unit is a winning display mode that is not permitted to be derived by the prior determination unit. Also, the progress of the game can be disabled.

  The winning display mode whose permission for derivation is not determined by the pre-determining means is derived to the variable display device. In particular, there is an abnormality in the control of the derivation control means due to the abnormality of the data stored in the data storage means. Often occurs. This also means that both the special display mode and the non-special mode are as serious as abnormalities derived from the variable display device. However, by disabling the progress of the game, Accurate control can be performed for occurrence. In addition, since it is assumed that it cannot be canceled easily as in the case where the progress of the game is controlled to be impossible in the originally scheduled game, it is possible to easily recognize that a serious abnormality has occurred. Become.

The slot machine according to the first and second aspects is as follows.
The game in the normal gaming state indicates that the pre-determining means permits the derivation of the small role display mode (watermelon, bell, cherry) accompanied by the addition of the gaming value when a predetermined special condition is established. Special game control means (steps S914 and S703) for controlling a special game (regular bonus) determined with a high probability for a predetermined period;
The game may further include special game determination means (steps S701 and S702) for determining whether or not the game is controlled by the special game in the special game state.

  Here, the special game control means starts control of the special game in the special game state as establishment of the special condition when it is determined by the special game determination means that the special game is not controlled. It can be assumed (step S703).

  The special game control means starts controlling the special game as the special condition is satisfied when the special game state is controlled, and starts controlling the special game in the special game state. When the predetermined period expires and control of the special game ends, the special condition is satisfied, and the control of the special game can be resumed in the special game state (modified example: big bonus At the end of the regular bonus, set the regular bonus medium flag at the end of the regular bonus).

  In the special game, since it is determined that the derivation of the small role display mode is allowed with high probability, it can be expected that the number of game values obtained by the player is increased. In the special gaming state, if it is determined that each game is not controlled by the special game, the game is immediately controlled by the special game. For example, one game is consumed by deriving a display result for controlling the special game. It will not happen. For this reason, the player can quickly obtain the benefit of providing gaming value in the special gaming state. This effect is particularly prominent when the special gaming state is ended when the number of gaming values given to the player reaches a predetermined number.

  In the former example, even when the special game is first controlled after the special display mode is derived, the special game is controlled again when the special game period has ended and the special state has not ended yet. However, the same processing may be performed. On the other hand, in the latter example, when the period of the special game is once ended and the special state has not yet ended, it is possible to immediately return to the special game.

In the slot machine according to the first and second aspects,
The variable display device rotates display bands (reels 3L, 3C, and 3R) each having a plurality of types of identification information that can be identified by driving a stepping motor (stepping motors 3ML, 3MC, and 3MR). A display result may be derived from each of a plurality of variable display units capable of variably displaying. in this case,
The slot machine is
A plurality of stop operation means (stop buttons 12L, 12C, 12R), which are provided corresponding to the plurality of variable display sections, respectively, and are operated when deriving display results in the corresponding variable display sections;
The derivation control unit may cause the variable display device to derive a display result in accordance with an operation procedure of the prior determination unit and the stop operation unit (step S404).

Here, the derivation control means is
In a situation where a display result has not yet been derived for any of the plurality of variable display units, a variable display unit for which a display result has not yet been derived is displayed at the time when the stop operation means corresponding to the variable display unit is operated. From a plurality of control patterns (FIG. 9: stop control table) that uniquely specify a display result derived with respect to the number of steps of the stepping motor, a control pattern corresponding to the determination result of the predetermining means is uniquely set Includes a control pattern selection means for specifying (step S805),
When the stop operation unit corresponding to the variable display unit for which the display result has not yet been derived is operated, the control pattern selected for the variable display unit by the control pattern selection unit is the step at the time of operation of the stop operation unit A display result uniquely specified for the number can be derived as a display result in the variable display unit (step S815).

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

The derivation control means includes
In a situation where a display result is derived to at least one of the plurality of variable display sections and a display result is not derived to another variable display section, the variable display section for which the display result has not been derived yet From a plurality of control patterns (FIG. 9: stop control table) that uniquely specify the display result derived with respect to the number of steps of the stepping motor at the time when the stop operation means corresponding to the section is operated Control pattern selection means (step S805) for uniquely specifying the control pattern corresponding to the number of steps when the corresponding stop operation means is operated in the variable display unit for which the determination result of the determination means and the display result has already been derived. Including
When the stop operation unit corresponding to the variable display unit for which the display result has not yet been derived is operated, the control pattern selected for the variable display unit by the control pattern selection unit is the step at the time of operation of the stop operation unit A display result uniquely specified for the number can be derived as a display result in the variable display unit (step S815).

Alternatively, the derivation control means includes
In a situation where a display result is derived to at least one of the plurality of variable display sections and a display result is not derived to another variable display section, the variable display section for which the display result has not been derived yet From a plurality of control patterns (FIG. 9: stop control table) that uniquely specify the display result derived with respect to the number of steps of the stepping motor at the time when the stop operation means corresponding to the section is operated Control pattern selection means (step S805) for uniquely identifying the control pattern corresponding to the combination of the determination result of the determination means and the display result in the variable display unit from which the display result has already been derived,
When the stop operation unit corresponding to the variable display unit for which the display result has not yet been derived is operated, the control pattern selected for the variable display unit by the control pattern selection unit is the step at the time of operation of the stop operation unit The display result uniquely specified for the number may be derived as the display result in the variable display unit (step S815).

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

In the slot machine according to the first and second aspects,
The pre-determining means indicates that the derivation of both the special display mode and the non-special display mode (cherry) accompanied by a predetermined payout other than the control to the special gaming state is permitted as the winning display mode. It is possible to include duplication determining means (regular bonus + cherry, big bonus (2) + cherry, big bonus (2) + cherry) determined in the game.

  When it is determined that the derivation of both the special display mode and the non-special display mode is permitted in this way, the non-special display mode is derived as the display result of the variable display device, thereby deriving the special display mode.

  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 centralized management computer or a call lamp installed on the game island, and a big bonus medium signal inputted from the game control board 101 via the reel relay board 103, A regular bonus in-progress signal, a reel control signal, a stop switch signal, a medal IN signal, a medal OUT signal, a winning status signal, and an illegal winning signal are output to the external device.

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

  Among these storage areas, in particular, the set value work 112-4 is an area for storing a set value for determining a winning probability of internal winning to be described later, and the parity storage area 112-7 is a RAM parity at the time of power-off. Is an area for storing The winning flag storage register and the winning flag storage register, which will be described later, are provided in the general work 112-2, and the special role temporary storage register and the general role temporary storage register are provided in the important work 112-1. A credit counter, which will be described later, is also provided in the important work 112-1. The general work 112-2 is cleared for each game, but the important work 112-1 is not cleared for each game. The RAM 112 is supplied with power from a backup power source even in the event of a power failure, and stores stored data.

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

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

  When the setting key switch 92 is turned on and the power is turned on, a setting change mode in which a setting value can be changed is entered. When the setting switch 91 is operated in the setting change mode, the setting value is updated one by one (when further operation is performed from the setting 6, the setting is returned to the setting 1). Then, when the setting key switch 92 is turned OFF after the start lever 11 is operated, the determined setting value after the change is stored in the setting value work 112-4. However, even when a new setting value is selected and stored in the setting value work 112-4 in the setting change mode, data in an area other than the setting value work 112-4 in the RAM 112 is not always cleared. Absent.

  If the data clear switch 95 is in the OFF state when the setting key switch 92 is turned on and the power is turned on, the data in the RAM 112 is not cleared and the setting change mode is entered, and the setting value changing operation is performed. It becomes possible. On the other hand, if the data clear switch 95 is also in the ON state when the power is turned on with the setting key switch 92 in the ON state, the setting change mode is entered after the data in the RAM 112 is cleared and the setting value is changed. Operation becomes possible. When the setting value changing operation is performed without clearing the data in the RAM 112, the state shifts to a state in which the game can be progressed in the gaming state controlled immediately before the changing operation. When the setting value changing operation is performed after the data in the RAM 112 is cleared, the state shifts to a state in which the game can proceed in the initial game state.

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

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

  The data stored in the RAM 112 except when the setting key switch 92 and the data clear switch 95 are in the ON state and the data in the RAM 112 is cleared when the control unit 110 of the game control board 101 is activated. RAM parity is calculated based on all data other than the data stored in the parity storage area 112-7, and compared with the RAM parity stored in the parity storage area 112-7.

  If the comparison result of the RAM parity matches when the setting key switch 92 is in the OFF state, the state before the power is turned off is restored based on the state stored in the RAM 112. On the other hand, if the comparison result of the RAM parity matches when the setting key switch 92 is in the ON state, the mode can be changed to the setting change mode and a new setting value can be set based on the operation of the setting switch 91. It becomes possible.

  On the other hand, if the comparison result of the RAM parity does not match, it is determined that the RAM is abnormal again, and the RAM abnormal error code is set to control the RAM abnormal error state, thereby making the progress of the game impossible. ing. The RAM abnormal error state is not canceled even if the first reset switch 48 or the second reset switch 93 is operated. The RAM abnormality error processing is canceled by setting a new setting value in the setting change mode after the data in the RAM 112 is cleared by setting the data clear switch 95 to the ON state. On the other hand, error states other than the RAM abnormal error state are canceled by operating the first reset switch 48 or the second reset switch 93.

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

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

  The big bonus (1) is won when the combination of “7-7-7” is arranged in any of the winning lines (five) in the initial gaming state or RT. The big bonus (2) is awarded when the combination of “BAR-7-7” is aligned on any of the winning lines (five) in the initial gaming state or RT. When the big bonus (1) or the big bonus (2) is won, the gaming state shifts to the big bonus. In the big bonus, the regular bonus described above is repeatedly provided until the end. While the gaming state is the big bonus, the big bonus medium flag is set in the RAM 112.

 The big bonus ends when the number of medals paid out to the player exceeds 465. Here, since the maximum payout number per game is 15, the upper limit of the payout medal number in the big bonus is 480. After the end of the big bonus, all operations of the player are invalid except for the payment of credits, and the game is controlled to a freeze state in which the game cannot be progressed for a certain period of time. In addition, after the big bonus ends, the game state is controlled to the initial gaming state.

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

  The watermelon is awarded when the combination of “Bell-Watermelon-Bell” is aligned on the winning line (1) in any gaming state, and 15 medals are paid out. Since the “watermelons” are not arranged at intervals of 5 frames or less for the reels 3L, 3C, and 3R, even if the watermelon is won in the internal lottery described later, the operation timing of the stop buttons 12L, 12C, and 12R May not win a watermelon. In addition, after winning a watermelon in the initial gaming state, the gaming state is controlled to a second RT described later for 100 games.

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

  Cherry will be awarded when the “Cherry” symbol is derived on any of the winning lines (5 or 1) for the right reel 3R in any gaming state, and 2 pieces per winning line. Medals will be paid out. When “Cherry” is stopped at the upper or lower stage of the right reel 3R in a gaming state other than the regular bonus, a total of four medals are paid out because the derivation is made on two pay lines. In addition, after winning the cherry in the initial gaming state, the gaming state is controlled to the second RT described later until the next regular bonus, big bonus (1) or big bonus (2) is won.

  “Cherry” on the right reel 3R is not arranged at an interval of 5 frames or less. Therefore, even if the cherry is won in the internal lottery described later, the cherry will depend on the operation timing of the stop buttons 12L, 12C, and 12R. May not win. As shown in FIG. 2, the fifth “cherry” of the right reel 3 </ b> R is disposed two above the seventh “BAR”. For this reason, when “BAR” is aligned on the lower line or the diagonal line from the upper left to the lower right, the regular bonus and the cherry are won at the same time. Such a display result is displayed on the variable display device 2. Is avoided by the reel control.

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

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

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

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

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

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

  Regular Bonus + Cherry, Big Bonus (1) + Cherry, Big Bonus (2) + Cherry are roles that are subject to internal lottery in the initial gaming state, the first RT or the second RT. The value of the common flag for these roles is 1, and a storage address for a common number of determination values is registered regardless of the set value. The regular bonus, the big bonus (1), and the big bonus (2) are roles that are subject to internal lottery in the initial gaming state, the first RT or the second RT. For these combinations, the value of the common flag is 0, and the storage address for the number of determination values is individually registered according to the set value.

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

  Replay (initial) is a role that is subject to internal lottery only in the initial gaming state. Replay (RT1) is a role that is subject to internal lottery only in the first RT. Replay (RT2) is a role that is subject to internal lottery only in the second RT. The common flag for these roles is 1, and a storage address for a common number of determination values is registered regardless of the set value.

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

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

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

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

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

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

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

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

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

  Further, it goes without saying that the medal payout rate in the big bonus and the regular bonus exceeds 1, and is higher than the medal payout rate in the second RT. That is, the big bonus or the regular bonus is the most advantageous gaming state for the player, and the second RT is the next advantageous gaming state. The relation of the medal payout rate according to the gaming state described here is the same when the set value is any one of 1-6.

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

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

  Next, storage of results of internal lottery and management of winning combinations will be described. FIG. 7 is a diagram for explaining an area for storing the result of the internal lottery and an area for managing winnings. That is, in the RAM 112, the winning flag storage register (2 bytes) shown in FIG. 7A, the special combination temporary storage register (1 byte) shown in FIG. 7B, and the general combination shown in FIG. A temporary storage register (1 byte), an index search register (1 byte) shown in FIG. 7D, and a winning flag storage register (2 bytes) shown in FIG. 7E are provided.

  Here, since the winning flag storage register and the winning flag storage register are provided in the general work 112-2, they are always cleared at the end of one game, but the special role temporary storage register is stored in the important work 112-1. Since it is provided, it is not cleared for each game. In addition, a bit that is “unused” in the winning flag storage register and the winning flag storage register is a bit that does not correspond to any combination, and its value is always 0 (provided that the illegal winning is inverted) Except when the data in the winning flag storage register is inverted).

  The winning flag of the lottery role determined to be won in the internal lottery is first set in the winning flag storage register. Here, the fact that the winning flag is set means that the corresponding bit changes from 0 to 1. For example, when the regular bonus is won, the regular bonus winning flag in the most significant bit of the upper byte of the winning flag storage register is set. When the regular bonus + cherry is won, two flags, a regular bonus winning flag and a cherry winning flag, are set in the winning flag storage register.

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

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

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

  In the index search register, data in the special role temporary storage register is written in the upper 4 bits, and data in the general role temporary storage register is written in the lower 4 bits. It corresponds directly to the data in the flag storage register. When a stop control table to be described later is created, a table index stored in the ROM 113 is referred to according to the data in the index search register.

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

  When the winning flag is set in the winning flag storage register, the regular bonus, the big bonus (1) or the big bonus is confirmed by confirming that both the upper byte and the lower byte of the winning flag storage register are not 0. It is determined whether or not there has been an illegal prize winning simultaneously with (2) and watermelon, bell, cherry or replay. If the reels are normally controlled, such an illegal winning may not occur. However, because of the arrangement of symbols on the reels 3L, 3C, 3R, the regular bonus and the cherry may be won at the same time. It is.

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

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

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

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

  FIG. 8 is a diagram showing a table index stored in the ROM 113. As shown in the figure, the table index stores the top address of the area where the data for table creation is stored for each internal winning situation. The internal winning status is not determined according to the winning flag storage register shown in FIG. 7A, but is determined according to the index search register shown in FIG. 7D. That is, the start address of the area where the table creation data is stored is registered in association with the value that the data of the index search register can take.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

  Although it is prohibited to win a regular bonus, big bonus (1) or big bonus (2) and watermelon, bell, cherry or replay at the same time, it is actually from the arrangement of the reels 3L, 3C and 3R. What can happen is the regular bonus and cherry winning simultaneously. In order to avoid this, it is necessary to perform control so that the fifth “cherry” of the right reel 3R is not stopped at the upper stage.

  When the regular bonus is won (including the case where the cherry is also won), when the right reel 3R is stopped as the third reel, the left and middle reels to be the first and second reels By controlling the reels 3L and 3C, control is performed so that “BAR” is not aligned with the lower winning line or the diagonal winning line from the upper left to the lower right (not to be tempered). Since “BAR” can be stopped at an arbitrary position for the inner reel 3C, when the inner reel 3C becomes the first reel, “BAR” may be stopped at the upper stage. When the inner reel 3C is the second reel, if the “BAR” is stopped at the upper stage for the left reel 3L that is the first reel, the “BAR” is stopped at the upper stage for the inner reel 3C, If “BAR” is stopped at the lower stage of the reel 3L, “BAR” may be stopped at the middle stage of the reel 3C.

  In the case where the regular bonus is won (including the case where the cherry is also won), when the right reel 3R is stopped as the first reel, the reel control in which the regular bonus is given priority over the cherry However, it is not necessary to stop the “BAR” of No. 7 at the lower stage. The case where the “BAR” of No. 7 can only be stopped at the lower stage within the pull-in range of 4 frames is when the stop button 12R is operated at the timing when it is positioned at the lower stage. Can be pulled up to the upper or middle level, so that the “BAR” of No. 7 is kicked off and the “BAR” of No. 1 is stopped at the upper stage of the right reel 3R.

  When the regular bonus is not won (including the case where the cherry is won), if the right reel 3R is stopped as the third reel, the left and middle reels to be the first and second reels It is not necessary to make “BAR” on any winning line under the control of 3L, 3R. Here, if the cherry is won, if the “cherry” can be stopped at the upper stage or the lower stage when the right reel 3R serving as the third reel is stopped, this may be stopped. If you have n’t won any cherries, you can kick “Cherry”.

  When the right reel 3R is stopped as the first or second reel when the regular bonus is not won, the “cherry” is kicked if the cherry is not won, but the cherry is also won. Then, “cherry” is stopped at the upper or lower stage of the right reel 3R. Even if “BAR” is tempered when the right reel 3R is stopped as the second reel, “BAR” is a winning line by stop control of the left reel 3L or the inner reel 3C as the third reel. You can avoid aligning the top.

  As described above, regardless of the regular bonus and cherry winning status, as long as normal reel control is performed, it is impossible to win the regular bonus and cherry at the same time. Therefore, when the regular bonus and the cherry are won at the same time, the ROM 113 storing the genuine program is replaced with the one storing the illegal program, or stored in the RAM 112 for creating the stop control table. This means that there is a high possibility that the stored data is not the data for creating the stop control table that should be.

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

  The commands transmitted from the game control board 101 to the effect control board 102 include at least a winning status notification command, a reel rotation command, a reel stop command, a winning information command, an illegal winning command, and a gaming state command. The commands transmitted from the game control board 101 to the effect control board 102 include other commands, but detailed description thereof is omitted.

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

  The winning information command indicates the type of winning generated according to the derived display result and the number of medals to be paid out with the winning when the normal display result is derived on the variable display device 2. Sent when a display result is derived on the display device 2 and a winning determination is made. The illegal winning command is transmitted when an illegal winning that results in simultaneous winning of the regular bonus and the cherry or an illegal winning that results in a winning combination for which the winning flag is not set is generated. The gaming state command indicates a gaming state applied in the next game, and is transmitted at the end of one game.

  The CPU 121 of the effect control board 102 performs various effects based on the commands sent from the CPU 111 of the game control board 101 as described above. As the effects executed by the control of the CPU 121, a continuous effect that is continuously performed for three game periods, a bonus winning effect that is performed when a regular bonus, a big bonus (1), or a big bonus (2) is won, and a big When the game is started in the initial gaming state, the freezing effect that is performed when the game is in the frozen state after the end of the bonus, the chance effect that is performed when a chance eye is derived as the display result of the variable display device 2 (In fact, there is an initial notification performed at the end of the previous game).

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

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

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

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

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

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

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

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

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

  Next, the RAM parity calculated here is compared with the RAM parity stored in the parity storage area 112-7, that is, the RAM parity calculated and stored at the previous power-off (step S105). Whether or not the data stored in the RAM is normal (step S106).

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

  If the setting key switch 92 is on in step S103, it is further determined whether or not the data clear switch 95 is on (step S109). If the data clear switch is not on, even if the setting key switch 92 is on, if the data clear switch 95 is not on, a RAM abnormality error will occur depending on whether the RAM abnormality error code is set or not. Then, it is determined whether the activation process has been performed (step S110).

  If the RAM abnormality error code is set, the data in the RAM 112 remains not normal data, and the routine again proceeds to the RAM abnormality error processing shown in FIG. If the RAM abnormality error code is not set, there is no problem in the data in the RAM 112, and only the setting value may be changed, so the process proceeds to step S112. On the other hand, if the state of the data clear switch 95 is ON in step S109, all the data stored in the RAM 112 is initialized except for the used area and the set value work 112-4 in the stack area 112-6. (Set value work 112-4 is rewritten to 0) (step S111). Then, the process proceeds to step S112.

  In step S122, the setting change process shown in FIG. 11 is executed to set a new setting value and store it in the setting value work 112-4. When the prohibition of interruption is canceled after the setting change process is completed (step S113), the game can proceed and the process proceeds to the game control process.

  FIG. 11 is a flowchart showing in detail the setting change process executed by the CPU 111 in step S112. In the setting change process, first, a setting changing flag indicating that the setting changing mode is being set is set in a predetermined area of the RAM 112 (step S201), and the setting value stored in the setting value work 112-4 is read. Temporary storage is performed in a predetermined area of the RAM 112-4 (step S202).

  Next, it is determined whether or not the read set value is in a normal range of 1 to 6 (step S203). If the set value is not within the normal range, the process proceeds to step S205. If the set value is not within the normal range (including the case where the RAM abnormality error processing has been performed due to the abnormality of the set value and the case where the set value is added in the next step S206 and becomes 7 after exceeding the normal range) The read set value is corrected to 1 (step S204), and the process proceeds to step S205.

  In step S205, it is determined whether an operation of the setting switch 91 has been detected. When the operation of the setting switch 91 is detected, the read setting value is incremented by 1 (step S206). Then, returning to the process of step S203, if the set value is 7 as a result of the addition, the set value is corrected to 1 in step S204. If the operation of the setting switch 91 is not detected, it is determined whether or not the operation of the start switch 41 is detected (step S207). If the operation of the start switch 41 is not detected, the process returns to the process of step S203, and again enters the state of waiting for the detection of the operation of the setting switch 91 and the start switch 41.

  When the operation of the start switch 41 is detected in step S207, the changed set value selected at that time is stored in the set value work 112-4 and the set value is confirmed (step S208). Thereafter, the process waits until the setting key switch 92 is turned off (step S209). If it is determined in step S209 that the setting key switch 92 has been turned off, the setting changing flag set in step S201 is cleared (step S210). And it returns to the flowchart of FIG. Returning to the flowchart of FIG. 10, after the prohibition of interruption is canceled in step S <b> 113, the game can proceed and the game control process is started.

  FIG. 12 is a flowchart showing in detail the RAM abnormality error process executed by the CPU 111 of the game control board 101. In the RAM abnormality error process, the game number display unit 51 is controlled to display the RAM abnormality error code on the game number display unit 21 (step S301), and then the process proceeds to a loop process in which no process is performed. Note that the RAM abnormality error processing shown in FIG. 12 is also performed when an abnormality in the set value or an abnormality in the number of bets is detected during an internal lottery to be described later.

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

  If the RAM parity does not match, the interrupt is not permitted. Therefore, once the process proceeds to the RAM abnormality error process, the setting key switch 92 is activated in the ON state until the interrupt prohibition is canceled. Even if the power is cut off, no power interruption processing is performed. That is, since no new RAM parity is calculated and stored in the power interruption process, the setting key switch 92 is turned on and the data clear switch 95 is turned on even when the control unit 110 is activated. Except in some cases, the RAM parities do not always match, so that the control unit 110 cannot be activated to start (resume) the game.

  Once the RAM abnormality error state is entered, the setting key switch 92 is turned on and the data clear switch 95 is turned on, the data in the RAM 112 is cleared, setting change processing is performed, and the setting switch 91 is operated. As a result, the game cannot be progressed until a new set value is selected and set. That is, after the transition to the RAM abnormal error state, the data in the RAM 112 is cleared, and the state where the game cannot be progressed is canceled on the condition that the setting value is newly selected / set by operating the setting switch 91. The game can be started (restarted).

  On the other hand, even if the setting key switch 92 is in the ON state, if the data clear switch 95 is started in the OFF state, the data in the RAM 112 is not cleared, and only a new setting value can be selected and set. However, if the setting key switch 92 is ON and the data clear switch 95 is OFF while being controlled to the RAM abnormality error state, the RAM abnormality error processing is controlled from the beginning to select a new setting value. Cannot set. Also, the RAM abnormal error state controlled by the fact that the set value or the number of bets is not appropriate in the internal lottery is not canceled unless the data in the RAM 112 is cleared and a new set value is set.

  Note that the error state other than the RAM abnormality error is an error state that can occur with a predetermined probability even when the possibility of an unauthorized operation is small, so the first reset switch 48 or the second reset switch Only by the operation of 93, the state in which the game cannot be progressed is canceled, and the game can be resumed. In addition, although it is not an error state, when the stop control is performed when a predetermined condition such as the end of the big bonus is satisfied and the game cannot be progressed, this is also the first reset switch 48 or It can be released only by operating the second reset switch 93.

  As described above, when the game can be progressed, the game processing is repeated one by one in the slot machine 1. Hereinafter, each game in the slot machine 1 will be described. The “game” in the slot machine 1 is, in a narrow sense, from the operation of the start lever 11 to the stop of the reels 3L, 3C, 3R. Since the bet number before the operation is set, the medals are paid out and the game state is shifted after the reels 3L, 3C, and 3R are stopped, these accompanying processes are also included in the “game” in a broad sense. .

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

  Next, the number of bets is set by operating one BET button 14 or MAXBET button 15 or by inserting medals from the medal insertion slot 13, and operating the start lever 11 to substantially change the game. BET processing for instructing start is performed (step S402). If the player has won a replay in the previous game, the same number of bets as in the previous game (3 in this embodiment) is automatically set by the replay game flag (the replay game flag is erased at this stage). ). Details of the BET process will be described later.

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

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

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

  When the winning determination process ends, a payout process is performed (step S406). In the payout process, the credit is increased by the number of payouts set in the winning determination process. However, when the number of credits accumulated as data reaches 50, the hopper motor 82 is driven to pay out an excess number of medals from the medal payout slot 71. In addition, various processes that are not related to winning (for example, a process related to the end control of the big bonus and the deletion of a winning flag that does not carry over) are also performed. At the end of the payout process, that is, at the end of one game, a game state command indicating the game state of the next game is sent to the effect control board 102. Details of the payout process will be described later. Then, the process for one game ends, and the process for the next one game starts.

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

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

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

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

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

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

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

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

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

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

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

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

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

  Next, the lottery process in step S403 will be described in detail. FIG. 17 is a flowchart showing in detail the lottery process executed by the CPU 111 in step S403. In the lottery process, it is determined whether or not the gaming state is the big bonus depending on whether or not the big bonus flag is set in the RAM 112 (step S701). If the gaming state is not the big bonus, the process proceeds to step S704 as it is.

  If the gaming state is in the big bonus, it is determined whether the gaming state is in the regular bonus depending on whether the regular bonus flag is set in the RAM 112 (step S702). If the game state is not in the regular bonus, it is the first game of the big bonus, or the game is a game when the regular bonus for one set in the big bonus has ended and the big bonus has not ended yet. A regular bonus medium flag is set to the game state and the gaming state is controlled to the regular bonus (step S703). Then, the process proceeds to step S704. If the gaming state is a regular bonus, the process proceeds to step S704 as it is.

  In step S704, the bet number set in the current game is read. Next, based on whether or not the regular bonus flag is set in the RAM 112, it is determined whether or not the gaming state is a regular bonus (including a case where the bonus is provided during the big bonus) (step S705). If there is a regular bonus, it is determined whether or not the read bet number is 1 (step S706). If not in the regular bonus, it is determined whether or not the read bet number is 3 (step S707). When the bet number read at step S706 is not 1 or when the bet number read at step S707 is not 3, a RAM error occurs, and the RAM error process shown in FIG. 12 is performed. When the bet number read in step S706 is 1, or when the bet number read in step S707 is 3, the process proceeds to step S708.

  In step S708, the setting value stored in the setting value work 112-4 of the RAM 112 is read. Here, it is determined whether or not the read set value is in the range of 1 to 6 that is a value that should be originally taken (step S709). If the read set value is not in the range of 1 to 6, a RAM abnormality error occurs and the RAM abnormality error process shown in FIG. 12 is performed.

  If the read set value is in the range of 1 to 6, random number acquisition processing is performed, and a random number generated by the random number generation circuit 115 is extracted by outputting a sampling command, and the random number generation circuit 115 extracts the random number. Store in the random number storage area. The random numbers for the internal lottery may be used after being processed by software according to a predetermined procedure instead of using the random numbers extracted from the random number generation circuit 115 as they are (step S710).

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

  If the common flag is set, the number of determination values stored in the address registered in the role-specific table of FIG. 5C corresponding to the read number of bets for the lottery object to be read is acquired ( Step S714). Then, the process proceeds to step S716. If the common flag is not set, the setting value set in the RAM 112 is read out and stored in the address registered in the combination table corresponding to the number of bets read and the setting value for the lottery target combination. The number of determination values is acquired (step S715). Then, the process proceeds to step S716.

  In step S716, the number of determination values acquired in step S714 or S715 is added to the internal lottery random value stored in the determination area of the RAM 112, and the result of the addition is used as a new internal lottery random value. Here, it is determined whether or not an overflow has occurred when the number of determination values is added to the value of the random number for internal lottery (step S717).

  If no overflow has occurred, it is determined whether there is a combination that is not yet a processing target among the lottery targets in the gaming state (step S718). If there is something that has not yet been processed, the process returns to the process of step S711, and the process continues with the next lottery target registered in the winning combination table by gaming state as the processing target. If there is nothing not to be processed, the process proceeds to step S728.

  If an overflow occurs, it is determined whether or not the lottery target combination read in the previous step S711 is any of regular bonus + cherry, big bonus (1) + cherry or big bonus (2) + cherry ( Step S719). In the case of regular bonus + cherry, big bonus (1) + cherry or big bonus (2) + cherry, at least the game state in the current game is a regular bonus (if provided during the big bonus) Not included).

  Here, whether the value of the special role temporary storage register is 0, that is, whether the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag has been carried over from the previous game. Is determined (step S720). If the value of the special role temporary storage register is 0, regardless of the current value, the value of the first RT counter is initialized to 0 and 102 is set in the second RT counter (step S721). Thus, the gaming state is controlled to the second RT until the regular bonus, the big bonus (1), or the big bonus (2) is won. Furthermore, the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is set in the winning flag storage register and the cherry winning flag is set in the winning flag storage register according to the read lottery target (Step S722). Then, the process proceeds to step S728.

  If the value of the special role temporary storage register is not 0 in step S720, the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is carried over from the previous game. Only the cherry winning flag is set in the winning flag storage register (step S723). Then, the process proceeds to step S728.

  In step S719, if the lottery target is neither regular bonus + cherry, big bonus (1) + cherry or big bonus (2) + cherry, the lottery target is regular bonus, big bonus (1) or big It is determined whether the bonus is (2) (step S724). If the lottery target is neither the regular bonus, the big bonus (1), or the big bonus (2), the process proceeds to step S727. If the bonus is one of the regular bonus, the big bonus (1), or the big bonus (2), whether or not the value of the special role temporary storage register is 0, that is, the regular bonus winning flag and the big bonus from the previous game. (1) It is determined whether the winning flag or the big bonus (2) the winning flag is carried over (step S725).

  If the value of the special role temporary storage register is not 0, the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag has been carried over from the previous game, so the process of step S728 is continued. Proceed to If the value of the special role temporary storage register is 0, the regular bonus, the big bonus (1) or the big bonus (2) is won, and the value of the first RT counter is set to 0 regardless of the current value. Initialization is performed and 102 is set in the second RT counter (step S726). Thus, the gaming state is controlled to the second RT until the regular bonus, the big bonus (1), or the big bonus (2) is won. Then, the process proceeds to step S727. In step S727, the winning flag of the lottery object combination is set in the winning flag storage register. Then, the process proceeds to step S728.

  In step S728, the lower byte of the winning flag storage register, that is, a value corresponding to the setting status of the winning flag for the general combination is stored in the general combination temporary storage register. Next, it is determined whether or not the upper byte of the winning flag storage register is 0, that is, whether the regular bonus, the big bonus (1), or the big bonus (2) is not won in the current game ( Step S729). If the upper byte of the winning flag storage register is not 0, the upper byte of the winning flag storage register, that is, a value corresponding to the setting state of the winning flag of the special role is stored in the special role temporary storage register (step S730). Then, the process proceeds to step S733.

  If the upper byte of the winning flag storage register is 0, whether the value of the special role temporary storage register is 0, that is, the regular bonus winning flag, big bonus (1) winning flag or big bonus (2 from the previous game) ) It is determined whether or not the winning flag has been carried over (step S731). If the value of the special role temporary storage register is not 0, the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is set in the upper byte of the winning flag storage register according to the value ( Step S732). Then, the process proceeds to step S733. If the value of the special role temporary storage register is 0, the process proceeds to step S733 as it is.

  In step S733, the value stored in the special role temporary storage register is written in the accumulator of the CPU 111. Further, the value of the lower 4 bits of the accumulator is shifted to the upper 4 bits (step S734). Next, the value stored in the general combination temporary storage register is added to the value stored in the accumulator, and this is stored in the accumulator (step S735). Then, the value stored in the accumulator is stored in the index search register (step S736).

  Furthermore, a winning status notification command is generated according to the setting status of the winning flag of each combination indicated by the winning flag storage register or the index search register, and is transmitted to the effect control board 102 (step S737). Then, the lottery process is terminated, and the process returns to the flowchart of FIG.

  Next, the reel rotation process in step S404 will be described in detail. FIG. 18 is a flowchart showing in detail the reel rotation process executed by the CPU 111 in step S404. In the reel rotation process, first, it is determined whether or not a wait time (for example, about 4.1 seconds) has elapsed since the reel rotation start time of the previous game (step S801). If the wait time has not elapsed, Wait until the wait time has elapsed. If the wait time has elapsed, the timing of the wait time is newly started (step S802).

  Next, the work initialization code at the start of the rotation of the reel motor is set in the register, and the rotation of the reel is started (step S803). At this time, a reel rotation command indicating that the reels 3L, 3C, 3R have started to rotate is generated and transmitted to the effect control board 102 (step S804).

  Thereafter, the table creation data is identified by referring to the table index corresponding to the value of the index search register, and based on the identified table creation data, the game state of the game, the internal winning status, and the stop of other reels A stop control table corresponding to the situation is created for each rotating reel (step S805). In addition, the work initialization code at the completion of the stop preparation is set in the register (step S806). Thereby, the operation of the stop buttons 12L, 12C, and 12R becomes valid.

  Next, it is determined whether any one of the stop buttons 12L, 12C, and 12R has been detected (step S807). If no operation of the stop button is detected, it is determined whether or not a reel rotation error (an error determined when the reel reference position is not detected by the reel sensors 3SL, 3SC, 3SR for a certain period or more) has occurred. (Step S808). If no reel rotation error has occurred, whether or not a further insertion error (an error determined when a medal insertion is detected outside the period during which medal insertion is permitted) has occurred, and a payout error It is determined whether or not an error has occurred (error determined when medal payout is detected outside the period during which medal payout is permitted) (steps S809 and S810). If no error is determined in steps S808 to S810, the process returns to step S807.

  If it is determined in step S809 that a loading error has occurred, or if a dispensing error has been determined in step S810, an error code indicating a loading / dispensing error during reel rotation is set in the register (step S810). In step S811, the process proceeds to predetermined error processing (step S812). If the error is released, the process returns to step S807 again.

  If it is determined in step S808 that a reel rotation error has occurred, an error code indicating a reel rotation error is set in the register (step S813), and the process proceeds to a predetermined error process (step S814). Along with this, the rotation of the reels 3L, 3C, 3R is also temporarily stopped. If the error is released, the process returns to step S803 again, and the rotation of the reels 3L, 3C, 3R is resumed.

  If the operation of the stop buttons 12L, 12C, 12R is detected in step S807, the reel motor (any of 3ML, 3MC, 3MR) corresponding to the operated stop button from the reel reference position at that time is detected. The number of steps (the number of steps at the stop operation position) is acquired and set to the work corresponding to the stop reel (step S815). Here, a reel stop command indicating the type of reel to be stopped and the symbols to be stopped for the reel is generated and transmitted to the effect control board 102 (step S816). Then, it waits until the rotation of the reel (any one of 3L, 3C, 3R) corresponding to the operated stop button stops (step S817).

  When the rotation of the reel (3L, 3C, or 3R) corresponding to the operated stop button stops, it is determined whether or not all of the reels 3L, 3C, and 3R have stopped (step S818). If the rotation of the reels 3L, 3C, 3R is not stopped, the process returns to step S805. If the rotation of all the reels 3L, 3C, 3R is stopped, the reel rotation process is terminated and the process returns to the flowchart of FIG.

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

  Next, the winning determination process in step S405 will be described in detail. FIG. 19 is a flowchart showing in detail the winning determination process executed by the CPU 111 in step S405. In the winning determination process, a winning flag corresponding to the role symbol derived on any winning line of the display result of the variable display device 2 is set in the winning flag storage register of the RAM 112. For example, when the regular bonus symbols are arranged on the winning line of the variable display device 2, the value of the most significant bit of the upper byte of the winning flag storage register is 1 and the values of the other bits are 0 (step) S901).

  Next, it is determined whether or not the upper byte of the winning flag storage register is 0 (step S902). If the upper byte is not 0, it is further determined whether or not the lower byte is 0 (step S903). If both the upper byte and the lower byte are not 0, it will be a case where a regular bonus, a big bonus (1) or a big bonus (2) and a watermelon, replay, cherry or replay are won at the same time (however, on the symbol arrangement) All you can do here is a regular bonus and a cherry win at the same time). In this case, the process proceeds to step S906.

  If either the upper byte or the lower byte of the winning flag storage register is 0, the value of each bit of the winning flag storage register of the RAM 112 is inverted. For example, when only the regular bonus winning flag is set, the value of the most significant bit of the upper byte of the winning flag storage register is 0 and the value of the other bits is 1. Then, the data of the winning flag storage register and the data of the winning flag storage register are logically ORed for each bit (step S904). Then, it is determined whether or not the result of the logical sum operation in step S902 is 0 (step S905).

  If the result of the logical sum operation in step S904 is not 0, it means that the winning combination for which the winning flag has not been set has been won. Also in this case, the process proceeds to step S906. In step S906, an illegal prize signal is output from the external output board 105 to the outside of the slot machine 1 (such as a central management computer of the amusement shop), and an illegal prize command indicating that an illegal prize has occurred is generated. Transmit to the control board 102. Then, the process proceeds to the RAM abnormality error process shown in FIG.

  If the result of the logical sum operation in step S904 is 0, it is determined whether or not a replay winning is made based on whether or not the replay winning flag is set in the winning flag storage register (step S907). If a replay prize has been won, a replay game flag is set in the RAM 112 (step S908). The replay game in-progress flag is deleted when the bet number is automatically set in the next game. Then, the process proceeds to step S922.

  If no replay winning is made, it is determined whether or not the big bonus (1) is won according to whether or not the big bonus (1) winning flag is set in the winning flag storage register (step S909). If the big bonus (1) has been won, the big bonus (1) winning flag is deleted, the big bonus medium flag is set in the RAM 112, and the value of the special combination temporary storage register is initialized to zero. Also, the values of the first RT counter and the second RT counter in the RAM 112 are both initialized to 0 (step S910). Then, the process proceeds to step S922.

  If the big bonus (1) has not been won, it is determined whether or not the big bonus (2) has been won based on whether or not the big bonus (2) winning flag is set in the winning flag storage register (step S911). If the big bonus (2) has been won, the big bonus (2) winning flag is deleted, the big bonus medium flag is set in the RAM 112, and the value of the special combination temporary storage register is initialized to zero. Also, the values of the first RT counter and the second RT counter in the RAM 112 are both initialized to 0 (step S912). Then, the process proceeds to step S922.

  If the big bonus (2) has not been won, it is determined whether or not the regular bonus has been won based on whether or not the regular bonus winning flag is set in the winning flag storage register (step S913). If the regular bonus is won, the regular bonus winning flag is deleted, the regular bonus medium flag is set in the RAM 112, and the value of the special combination temporary storage register is initialized to zero. Further, the values of the first RT counter and the second RT counter in the RAM 112 are both initialized to 0 (step S914). Then, the process proceeds to step S922.

  If there is no regular bonus winning, the regular bonus medium flag is not set in the RAM 112, and the game state in this game is the initial game state depending on whether both the first RT counter and the second RT counter are 0 or not. Is determined (step S915). If the game state in the current game is not the initial game state, the process directly proceeds to step S922.

  If the game state in the current game is the initial game state, it is determined whether or not a bell is won depending on whether or not a bell winning flag is set in the winning flag storage register (step S916). If the bell is won, 1001 is set as the initial value of the first RT counter in the RAM 112 (step S917). Here, to set 1001 as the initial value, the value of the first RT counter is decremented by 1 in step S1009 (described later) until the next game is started. This is to secure 1000 games as the number of games. Then, the process proceeds to step S922.

  If the bell has not been won, it is determined whether or not a watermelon has been won depending on whether or not a watermelon winning flag is set in the winning flag storage register (step S918). If the watermelon has been won, 101 is set as the initial value of the second RT counter in the RAM 112 (step S919). Here, in order to set 101 as the initial value, the value of the second RT counter is decremented by 1 in step S1011 (described later) until the next game is started. This is to secure 100 games as the number of games. Then, the process proceeds to step S922.

  If there is no watermelon winning, it is determined whether or not a cherry is won according to whether or not a cherry winning flag is set in the winning flag storage register (step S920). If the cherry is won, 102 is set as the initial value of the second RT counter in the RAM 112 (step S921). Here, by setting 102 as the initial value, how many games have elapsed until the value of the second RT counter is initialized to 0 after winning the regular bonus, the big bonus (1) or the big bonus (2). However, the gaming state is controlled to the second RT. Then, the process proceeds to step S922.

  In step S922, the type of winning combination based on the winning flag set in the winning flag storage register (however, the winning flag is not set in the case of losing) and the number of medals to be paid out with the winning are displayed. A winning information command is generated and transmitted to the effect control board 102. Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  Next, the payout process in step S406 will be described in detail. FIG. 20 is a flowchart showing in detail the payout process executed by the CPU 111 in step S406. In the payout process, it is determined whether or not there has been a small role winning accompanied by paying out medals depending on whether or not a winning flag of watermelon, bell, or cherry is set in the RAM 112 (step S1001). If the small role is not won, the process proceeds to step S1003.

  If the small role winning is achieved, the number of medals is sequentially paid out by controlling the hopper 80. However, until the number of credits accumulated as data reaches 50, instead of paying out medals, the number of credits is increased (step S1002). Then, the process proceeds to step S1003.

  Here, it is determined in step S1001 that the small role has not been won, or it is determined that one game has been completed by finishing the medal payout in step S1002. That is, when the small role is won, it is determined that the game is over when the payout of the medal is completed. This is the same as determining that the game is over when the result is derived. The operation of the checkout button 16 is effective here, but the operations of the single BET button 14 and the MAXBET button 15 are not yet effective.

  In step S1003, it is determined whether or not the current gaming state is a regular bonus (including those provided during the big bonus) depending on whether or not the regular bonus flag is set in the RAM 112. If the current gaming state is not a regular bonus, the process proceeds to step S1007. 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 S1004).

  As a result of the counting, it is determined whether or not a regular bonus end condition has been met (step S1005). 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 S1006). Here, since the value of the first RT counter and the value of the second RT counter are both 0, the gaming state in the next game is the initial gaming state. Then, the process proceeds to step S1007. Even if the regular bonus is not terminated, the process proceeds to step S1007.

  In step S1007, it is determined whether or not the current gaming state is a big bonus depending on whether or not the big bonus flag is set in the RAM 112. If the current gaming state is not a big bonus, it is determined whether or not the value of the first RT counter in the RAM 112 is greater than 0 (step S1008). If the value of the first RT counter is larger than 0, the value of the first RT counter is subtracted by 1 (step S1009), and the process proceeds to step S1012. If the value of the first RT counter is 0, it is further determined whether or not the value of the second RT counter is larger than 0 and smaller than 102 (step S1010). If the value of the second RT counter is larger than 0 and smaller than 102, the value of the second RT counter is decremented by 1 (step S1011), and the process proceeds to step S1012. If the value of the second RT counter is 0 or 102, the process proceeds to step S1012.

  In step S1012, based on the big bonus medium flag and the regular bonus medium flag in the RAM 112, and the values of the first RT counter and the second RT counter, a game state command indicating a gaming state applied in the next game is generated, Transmit to the control board 102. Then, the process proceeds to step S1024.

  If the current gaming state is a big bonus in step S1007, the number of payout medals in the big bonus is counted using the counter of the RAM 112. The number of payout medals counted here exceeds 465, and it is determined whether or not the big end condition is satisfied (step S1014). If the big bonus end condition is not satisfied, a game indicating a gaming state applied in the next game based on the big bonus medium flag and the regular bonus medium flag in the RAM 112 and the values of the first RT counter and the second RT counter. A state command is generated and transmitted to the effect control board 102 (step S1015). Then, the process proceeds to step S1024.

  If the big bonus end condition is satisfied, the big bonus medium flag in the RAM 112 is deleted. If the regular bonus medium flag is set, it is also deleted. In addition, since there may be a regular bonus in the big bonus that initializes the value of the counter for counting the number of paid-out medals in the big bonus, the value of the counter for counting the number of games and winnings in the regular bonus Is initialized (step S1016). Here, since the value of the first RT counter and the value of the second RT counter are both 0, the gaming state in the next game is the initial gaming state.

  Further, a gaming state command indicating a gaming state (here, always a big bonus) applied in the next game based on the big bonus medium flag and the regular bonus medium flag in the RAM 112 and the values of the first RT counter and the second RT counter. Is generated and transmitted to the effect control board 102 (step S1017). Here, timing of the wait time is started using the internal timer of the CPU 111 (step S1018).

  When the timing of the wait time is started, it is determined whether or not the value of the credit counter in the RAM 112 is 0 (step S1019). If the value of the credit counter is 0, the process proceeds to step S1023. If the value of the credit counter is not 0, it is determined whether or not an operation of the settlement button 16 is detected by the settlement switch 47 (step S1020). When the operation of the settlement button 16 is detected, the settlement process shown in FIG. 16 is performed (step S1021). Then, the process proceeds to step S1023. In step S1023, it is determined whether or not the time being measured has reached the specified weight time. If the specified time has not been reached, the process returns to step S1019. If the specified time has been reached, the process proceeds to step S1024.

  In step S1024, all the winning flags set in the winning flag storage register and the winning flags set in the winning flag storage register are erased. This process is realized by a process of clearing the general work 112-2 for each game. In this game, the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is set and the regular bonus, big bonus (1) or big bonus (2) is not won. Even in such a case, since the value of the special role temporary storage register is not cleared, the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is carried over to the next game. On the other hand, since the value of the general combination temporary storage register is always rewritten according to the result of the internal lottery of the next game, the winning combination flag of the general combination is not carried over to the next game.

  When the general work 112-2 is cleared in step S1024, the operation of the single BET button 14 and the MAX BET button 15 is also valid here. Then, the payout process is terminated, and the process returns to the flowchart of FIG. Here, when returning to the flowchart of FIG. 13, the process in the current one game ends.

  In the repetition of the game as described above, the CPU 111 of the game control board 101 performs the transition of the game state among the initial game state, the first RT, the second RT, the big bonus, and the regular bonus, depending on the progress of the game. The command is transmitted to the effect control board 102. On the other hand, the CPU 121 of the effect control board 102 performs an original effect as described above based on the command received from the game control board 101. A detailed description of these effects will be omitted.

  Further, although it is not an effect that is performed according to the progress of the game, when the CPU 121 of the effect control board 102 receives an illegal winning command, a regular bonus, a big bonus (1) or a big bonus (2) and a watermelon, A predetermined image is displayed on the liquid crystal display 4 or a speaker 7L, 7R, or 7 is displayed, indicating that there has been an illegal prize such as a simultaneous prize of Bell, Cherry or Replay, or an illegal prize such as a prize for which a winning flag is not set. Notification may be made by outputting a predetermined sound from 7U.

  As described above, in the slot machine 1 according to this embodiment, the regular bonus, the big bonus (1), and the big bonus (2) are special bonuses among the winning winning roles, and the watermelon, bell, and cherry are the minor bonuses. However, replay is defined as a re-playing role. Of these, cherry is a single symbol winning combination that is awarded only when “cherry” is derived to the right reel 3R, considering only the relationship of the symbol arrangement on the reels 3L, 3C, and 3R. If there is a possibility of combination, “cherry” may be derived on the right reel 3R, and “BAR” may be aligned on the winning line.

  Here, the regular bonus and the cherry have completely different types of value given to the player by winning, so the reels 3L, 3C, and 3R are controlled to stop winning at the same time. . Winning a regular bonus and a cherry at the same time in one game, or winning a new cherry with a regular bonus win flag carried over can occur as a result of normal game progress. However, the reels 3L, 3C, and 3R are controlled so as not to win at the same time so that different types of values corresponding to each are not given in one game and the shooting performance is not increased. Yes.

  As long as the stop control of the reels 3L, 3C, and 3R is normally performed, the problem of simultaneous winning of regular bonus and cherry does not occur. In other words, even if the regular bonus and the cherry are simultaneously won, the reels 3L, 3C, and 3R are controlled so that the regular bonus is derived in preference to the cherry, so both games are won in one game. There is nothing. If an abnormality occurs in the stop control of the reels 3L, 3C, 3R, the cherry blossom is a single symbol winning combination with only the right reel 3R, and the regular bonus and cherry are There may be cases where simultaneous winnings occur.

  This was originally not planned as a game progress control in the slot machine 1, but it can be considered that the cause is from ROM 113 storing a genuine program to ROM storing an illegal program. Exchange, a serious bug in the program, the data in the RAM 112 for creating the stop control table is data that is not possible (that there is a possibility of rewriting to illegal data), It is thought that a very serious abnormality occurred.

  In the slot machine 1, when such a simultaneous winning abnormality occurs, the control of the RAM abnormality error process is performed to disable the progress of the game. The RAM abnormality error processing is not canceled only by operating the first reset switch 48 or the second reset switch 93 like other types of errors, and the RAM 112 data must be initialized and a new set value must be set. It will not be released. For this reason, even if a serious anomaly such as regular bonuses and cherries wins simultaneously, not only is the correct response made by disabling the progress of the game, but it is also easy for the state where the progress of the game is impossible Therefore, it is possible to easily recognize that a serious abnormality has occurred.

  Also, if you win a role that does not have a winning flag set, it can be considered that the reason for the occurrence is the same as the cause of the above-mentioned regular bonus and cherry winning simultaneously, which is very serious. It is thought that an abnormal abnormality occurred. Even if a serious abnormality such as winning of a winning combination for which a winning flag is not set is controlled by RAM abnormality error processing, an appropriate response is made by disabling the progress of the game. In addition, since it is assumed that the state in which the game cannot be progressed is not easily released, it becomes possible to easily recognize that a serious abnormality has occurred.

  In addition, as a control of one game in the slot machine 1, a payout process in which a medal payout based on a small winning prize is actually performed is executed after the winning determination process is completed. Here, if it is determined that a regular bonus and a cherry are simultaneously won in the winning determination process or a winning combination for which a winning flag is not set is determined, a RAM abnormality error process is performed before the process proceeds to a payout process. It is supposed to migrate. That is, in such an illegal winning, even if a small role winning is made from the viewpoint of the display result of the variable display device 2, an actual medal is not paid out. For this reason, it is possible to prevent the inconvenience that medals are paid out to the player when such a serious abnormality occurs.

  Further, when it is determined that the regular bonus and the cherry are won simultaneously, or it is determined that the winning combination is not set, the illegal winning command is transmitted to the effect control board 102 and the illegal winning signal is externally transmitted. Output from the output board 105 to an external device. Based on the illegal winning command, the liquid crystal display 4 of the slot machine 1 and the speakers 7L, 7R, 7U are notified of the occurrence of a serious abnormality, the call lamp on the game island is turned on, the central management computer of the amusement store According to the point of monitoring in the game store, it is possible to easily recognize the occurrence of a serious abnormality such as a regular bonus and cherry winning simultaneously and a winning combination with no winning flag set.

  In order to change the setting value, the setting key switch 92 is turned on and the slot machine 1 is started. In the setting change mode shifted here, the setting switch 91 is operated to select a desired setting value and start. It is necessary to turn off the setting key switch 92 after operating the lever 11. Here, when only the setting key switch 92 is turned on and the data clear switch 95 is turned off, the setting value can be changed, but the other works 112-1 to 112-3 of the RAM 112, etc. Will not be cleared. In order to clear the data of other works 112-1 to 112-3 etc. of the RAM 112, it is necessary to activate not only the setting key switch 92 but also the data clear switch 95 and activate the slot machine 1.

  For this reason, when only the setting value is changed without turning the data clear switch 95 ON, the data relating to other games remains stored in the RAM 112, and therefore, the setting was made before the setting value was changed. The situation in the game (excluding the internal lottery winning probability) is inherited in the game after the set value is changed. For example, the credits and the number of bets accumulated before the setting value is changed are kept as they are, and the gaming state controlled before the setting value is changed continues after the setting value is changed. For this reason, there is no difference before and after the setting value is changed except for the winning probability of the internal lottery.

  Changing the set value only changes the winning probability of the internal lottery, but there is only a difference as a problem of probability, and as long as the number of digest games after changing the set value is small, the winning of the internal lottery The player cannot predict that the probability has changed, that is, that the set value has been changed. Even if the set value can be predicted to some extent depending on the probability of winning an unmissable role such as a bell or replay, a considerable number of games must be completed before reaching that point. For this reason, in situations where multiple slot machines are in operation at the amusement store, the player immediately knows that the set value has been changed between the closing and opening of the previous day. As a result, there is no stand that prevents the player from approaching, and the operating rate of each stand does not decrease.

  On the other hand, in the slot machine 1 according to this embodiment, when an abnormality occurs in the data stored in the RAM 112, it is controlled to a RAM abnormality error state and the progress of the game is disabled. In this case, not only the setting value is changed, but also the data clear switch 95 is activated with the setting key switch 92, the data in the RAM 112 is cleared, and a new setting value is set in the subsequent setting change mode. Otherwise, the state where the progress of the game is disabled is not released. Even if the setting key switch 92 is activated with only the ON state, it is controlled again to the RAM abnormal error state before the setting value is changed. The same applies when the number of bets and set values are not appropriate in the internal lottery of each game.

  In this way, when an abnormality occurs in the data stored in the RAM 112, not only the setting value is changed, but a new game cannot be started unless the data in the RAM 112 is cleared. The game is not played based on the above, and the fairness of the game can be achieved. Moreover, if there is an abnormality in the set value and the number of bets, there is a high possibility that fraud is being performed, but since this is determined for each game, the game is performed with unauthorized data. Can be prevented as much as possible.

  However, it is the same in the conventional slot machine that a new game cannot be started unless the data in the RAM 112 is cleared. In the conventional slot machine, the setting value is changed and the data in the RAM 112 is cleared by a series of operations. In such a case, the default setting value (usually setting value 1) is automatically selected and set. It was supposed to be. For this reason, the winning probability of the internal lottery becomes different from the probability that was intended on the side of the amusement store, and in the setting value 1 that is generally automatically selected, the amusement store inherently sets the setting value 1. There was a problem that the disadvantage of the player would be large except when intended.

  When an abnormality occurs in the data stored in the RAM 112, it is necessary to first clear the data in the RAM 112. In this case, instead of the setting value automatically set by the slot machine 1, a setting change operation is performed. It is guaranteed that the game is played based on the set value selected and set based on the game (generally, since the setting change operation is performed by an amusement store employee, the set value is selected by the amusement store side). Therefore, the fairness of the game can be achieved.

  In addition, the data stored in the RAM 112 is abnormal when the player is not cheated or when the control unit 110 runs out of control, such as when a power failure occurs or the control unit 110 runs out of control. Is almost. In addition to the determination of the setting value and the number of bets that are likely to be determined to be fraudulent, it is determined whether or not the data is normal only when the control unit 110 is activated after recovering from the state where the control has failed. Therefore, it is possible to determine whether or not the data stored in the RAM 112 is normal only in a situation where there is a high possibility that the data is abnormal. That is, in a situation where there is a low possibility that an abnormality has occurred in the data stored in the RAM 112, it is not necessary to perform the determination, and the load on the control unit 110 can be reduced.

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

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

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

  Further, only the data of the set value work 112-4 is changed only by changing the set value, but the data clear switch 95 is also turned on and the data of the other works 112-1 to 112-3 etc. of the RAM 112 are also cleared. As a result, the initial gaming state is controlled. By being controlled to the initial gaming state, a chance to be controlled by the second RT is newly given to the player. Even if the game state before the data of the workpieces 112-1 to 112-3 other than the set value workpiece 112-4 in the RAM 112 is cleared is not inherited, the player may not get close to it. Absent.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

  In addition, in the initial gaming state or RT, the number of determination values includes those for which both regular bonus, big bonus (1), big bonus (2) and cherry are subject to lottery. Here, if none of the regular bonus winning flag, big bonus (1) winning flag, and big bonus (2) winning flag has been carried over from the previous game, depending on the value of the random number for internal lottery, Both the big bonus (1) or the big bonus (2) and the cherry are won.

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

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

  In addition, in order to check whether or not an illegal winning of a combination for which no winning flag is set has occurred, a winning flag storing register having the same form as the winning flag storing register is prepared, and the winning display line on the variable display device 2 is provided. In the upper byte of the winning flag storage register that sets the winning flag corresponding to the combination of symbols, the regular bonus, the big bonus (1) and the big bonus (2) winning flags are set, and the lower byte is a watermelon. , Bell, cherry and replay winning flags are set.

  Check if the regular bonus, big bonus (1) or big bonus (2) and watermelon, bell, cherry or replay are won at the same time (actual bonuses can be made with regular bonus and cherry) To do this, it is only necessary to check whether the upper byte and the lower byte of the winning flag storage register are 0. As a result, it is possible to easily determine an illegal winning that is a simultaneous winning of the regular bonus, the big bonus (1) or the big bonus (2) and the watermelon, bell, cherry or replay.

  In addition, in order to check whether or not an illegal winning of a role for which the winning flag is not set has occurred, the logic of the winning flag storage register is logically inverted and then the data and the bit of the winning flag storage register are logically A product operation is performed. Thus, it is not necessary to individually compare the winning flag and the derived display result, and it is possible to easily determine an illegal winning such as winning of a combination for which no winning flag is set.

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

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

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

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

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

  In the above embodiment, the operation of clearing the data in the RAM 112 is to turn on the data clear switch 95 when the setting key switch 92 is turned on to start the operation. Some operations were common to the change. On the other hand, the data in the RAM 112 may be cleared by an operation completely different from the operation of changing the set value. Further, by performing different operations on the same operation means, it may be possible to simply perform a setting value change operation and clear data in the RAM 112. Even if the data clear switch 95 is not provided, the data in the RAM 112 is cleared as it is in step S111 by starting with the setting key switch 92 turned ON (that is, the processes in steps S109 and S110 are not executed). Thereafter, a new set value may be set by the setting change process in step S112.

  In the above embodiment, the setting key switch 92 and the data clear switch 95 are activated and activated, and the RAM 112 can be recovered from the RAM error state by clearing the data of the RAM 112 and setting a new set value. It was. On the other hand, even if the setting key switch 92 is turned on without setting the data clear switch 95 to ON, and a new setting value is set without clearing the data in the RAM 112, the RAM abnormal error state can be detected. It may be possible to return.

  For example, if an abnormal set value is determined in steps S708 and S709, there is a possibility that only the set value data is damaged due to the influence of noise or the like. In addition, even when both the regular bonus and the cherry are won, or when the winning combination is not set, the data in the RAM 112 is abnormal. There is a high possibility that the data has been manipulated. As an illegal operation of data in the RAM 112, there is a very high possibility that the setting value will be illegally rewritten. Therefore, even if the data in the RAM 112 is not cleared, the RAM abnormal error state may be canceled if a new set value is set.

  In this case, if the illegal data remains without clearing the data in the RAM 112, the RAM abnormality error processing is repeatedly generated. In such a case, the data clear switch 95 may be activated again together with the setting key switch 92 to clear the data in the RAM 112. In this case, even if the RAM 112 is controlled to an abnormal error state, if the data in the RAM 112 is not abnormal enough to prevent the normal game as a whole, the data in the RAM 112 is unnecessarily cleared and returned to the initial gaming state. It wo n’t happen.

  In the above embodiment, when the data in the RAM 112 is cleared in step S111, only the data of the set value work 112-4 is not cleared. Of course, when the data in the RAM 112 is cleared, the setting value stored in the setting value work 112-4 may be set as an initial value (for example, 1), and subsequently, the setting value changing mode may be entered.

  Further, in the case where the operation for clearing the data in the RAM 112 and the operation for changing the set value are completely separate operations, even if the set value is not changed, the RAM error error state is obtained only by clearing the data in the RAM 112. It is good also as what can be canceled. Here, in the case where only the data of the set value work 112-4 is not cleared, the data of the set value work 112-4 is normal even if it is determined in steps S708 and S709 that the set value work 112-4 is abnormal. In some cases, it has been determined that a good judgment has been made. In this case, it is possible to return to a normal game without setting the set value again. If the data of the setting value work 112-4 is abnormal, the process proceeds to the RAM abnormality error processing again, so that it is only necessary to change the setting value again.

  In the above embodiment, the cherries have been defined as the possibility of winning the regular bonus, the big bonus (1) or the big bonus (2) at the same time in one game. It may be a small role or a replay. When there are a plurality of types of replay roles, one of them can be a regular bonus, a big bonus (1), or a big bonus (2) that can be won simultaneously in one game. Furthermore, a role that may be won simultaneously in one game with a regular bonus, a big bonus (1), or a big bonus (2) controls the gaming state to the RT without paying out medals or granting a replay. It is good also as the only role.

  In the embodiment described above, when determining an illegal winning, the data of each bit of the winning flag storage register is logically inverted, and the logical product operation is performed on the data of each bit of the winning flag storage register. On the other hand, the data of each bit of the winning flag storage register may be logically inverted, and this and the data of each bit of the winning flag storage register may be ORed. In this case, if the calculation result is 1, there is no illegal prize, and if it is 0, an illegal prize has occurred. Note that these operations can be appropriately changed depending on whether the bit indicating winning or winning is set to 0 or 1 or using positive logic or negative logic for the operation.

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

  In the above embodiment, when a game state command is received at the end of one game, an initial notification is made based on this. Therefore, in the first game after the data in the RAM 112 is cleared, the player is not notified that the game is performed in the initial game state although the game is controlled in the initial game state. Therefore, a game state command may be transmitted from the game control board 101 to the effect control board 102 at the start of one game, and based on this, an initial notification may be made at the start of one game.

  Furthermore, the initial notification indicating that such a gaming state is controlled to the initial gaming state may not be performed at all. Here, the first RT has no difference in replay winning probability that can be distinguished from the initial gaming state. For this reason, even if it is actually controlled by the first RT, the player can be expected to be controlled in the initial gaming state that may be controlled by the second RT.

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

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

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

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

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

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

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

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

  When there are two types of initial game states A and B in this way, for example, the game state is controlled to the initial game state A after the regular bonus ends, and the game is moved to the initial game state B after the big bonus ends. It is good also as what controls a state. In addition, when the first RT is completed due to the digestion of the prescribed number of games, the gaming state can be controlled to the initial gaming state A. It should be noted that the gaming state can be controlled to the initial gaming state A after the setting value changing operation is completed after clearing the data in the RAM 112.

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

  On the other hand, the initial gaming state B after the regular bonus has ended may be shifted to the second RT, so the player's expectation will not be reduced just because the regular bonus has been reached. Furthermore, the player's expectation for the big bonus can be further enhanced by controlling to the initial gaming state A instead of the initial gaming state B after the first RT is ended by digestion of the prescribed number of games. The interest of the game can be improved. Since the initial gaming state controlled after the RAM 112 data is cleared and the setting value changing operation is completed is the initial gaming state A, the initial gaming state B having a high probability of shifting to the second RT is associated with the big bonus. Thus, it is possible to achieve a special initial gaming state, to further increase the player's expectation for the big bonus, and to improve the interest of the game.

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

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

  In the above embodiment, at the end of the big bonus, the freeze effect is controlled such that the progress of the game is disabled for a certain period of time and all the effects are stopped. It may be performed at the start of the game, that is, immediately after winning the big bonus (1) or the big bonus (2). Even when the freezing effect is performed at the start of the big bonus, only the settlement of credits can be performed as in the case of performing the freezing effect at the end of the big bonus. Furthermore, it is also possible to perform stop control that disables the progress of the game until a predetermined operation (such as a reset operation) is performed after the big bonus has ended. Even when the stop control is performed, only the credit settlement can be performed as in the case where the freeze effect is performed.

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

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

  In the above embodiment, the internal lottery sequentially adds the number of judgment values for each combination according to the gaming state to the acquired random number for internal lottery, and the combination is won when the addition result overflows. 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 according to the number of determination values for each combination in accordance with the gaming state, 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 determination value number storage area uses a 2-byte area to store the determination value number in each case. However, in a general slot machine, the number of judgment values for a combination such as regular bonus, big bonus (1), or big bonus (2) may exceed 255 in any gaming state. Absent. Thus, for those that do not need to set the number of determination values exceeding 255, the number of determination values may be stored using only a 1-byte area.

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

  In the above embodiment, in the initial gaming state, the first RT or the second RT, the game can be started only by setting 3 as the bet number. On the other hand, even in the initial gaming state, the first RT or the second RT, the game can be started by setting 1 as the bet number, and further, the game can be started by setting 2 as the bet number. You may be able to do that.

  In the initial gaming state, when 1 or 2 is set as the bet number in the first RT and the second RT, the winning probability of the small role in the internal lottery is lowered and smaller than the case where 3 is set as the bet number. It is possible to increase the number of medals to be paid out when winning. In addition, in a slot machine in which any of 1, 2, or 3 can be set as the number of bets in the initial gaming state, the first RT and the second RT, the number of determination values is stored in common for all of the setting values 1 to 6. In addition, there may be a combination that is stored in common for all bets 1 to 3. In this case, the storage area for the number of determination values can be reduced according to the number of bets, and the storage capacity can be further reduced.

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

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

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

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

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

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

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

It is a figure which shows the arrangement | sequence of the symbol on each reel which comprises a variable display apparatus. FIG. 2 is a block diagram showing an overall configuration of a control circuit of the slot machine of FIG. 1. It is a figure which shows the storage area of RAM in a game control board.
