Abstract

<P>PROBLEM TO BE SOLVED: To make the completion of a specified game status, in which a probability for determining the allowance for the guiding out of a re-game displaying result is made higher than a normal game status, hard to be estimated by a game player, and to make the game player expect the continuation of the specified game status until the specified game status actually ends. <P>SOLUTION: Virtual reels corresponding to three reels which constitute a variable displaying device are displayed on a liquid crystal displaying device, and a display result corresponding to the display result of the variable displaying device is introduced by the virtual reels. When RT patterns (white 7-bell-JAC) are introduced on the variable displaying device, the game status is controlled by RT. In this case, the display configuration of the virtual reels becomes "something other than water melon-water melon-water melon". The liquid crystal displaying device is informed that the game status is controlled by the RT, but the information is started only when an RT information lottery is won in a game after the game status is controlled by the RT. Also, any information by which a quantity of RT remaining games can be specified is not informed. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

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

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

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

  However, in order for the winning combinations described above to occur, generally, a winning flag must be set by winning an internal lottery performed in advance (usually when the start lever is operated). Therefore, whether or not a winning in the slot machine occurs, that is, the profit / loss of the player depends on whether the winning probability of the internal lottery is high or low before the player can operate the stop button at an appropriate operation timing. It will be decided to some extent.

  Here, even when the game is performed in the same slot machine, if the winning probability of the internal lottery increases or decreases, the gameability should be improved. Therefore, in addition to a gaming state called a bonus such as a big bonus or a regular bonus, there is a specific gaming state (probability variation state) in which the winning probability of the internal lottery is higher than the normal gaming state by a predetermined number of games. There has been a slot machine. For example, RT (Replay Time) that increases the winning probability of replay without changing the winning probability of a role other than replay is known as a typical specific gaming state. Here, as an opportunity to shift to a specific gaming state such as RT, there is one in which a predetermined display result is derived to a variable display device in the same manner as an opportunity to shift to a bonus (for example, Patent Document 1). reference).

JP-A-6-335560 (paragraph 0106)

  By the way, in a conventional general slot machine, when a bonus symbol is derived as a display result of a variable display device, that is, when a gaming state is shifted to a bonus due to a bonus winning, in order to improve a player's expectation Bonus production was to be performed. When the derivation of a predetermined display result is applied as an opportunity to control to the probability variation state as in the slot machine of Patent Document 1, an effect indicating that the control is performed to the probability variation state by derivation of the predetermined display result may be performed. it can. Here, if the player counts the number of digested games from the start of this production, it is possible for the player to predict when the gaming state in which the winning probability of the internal lottery is increased will end in this way. The player cannot expect to continue the specific gaming state beyond that.

  On the other hand, if the player does not produce any effect even if the predetermined display result is derived and controlled to the probability variation state, if the player misses the derivation of the predetermined display result, the player There will be no way of knowing that it has been controlled in a fluctuating state. For this reason, it does not know whether the winning frequency during several games has increased, because it is based on the fact that it is controlled by the probability fluctuation state, or just because the winnings happen to overlap, It will not be possible to give the player a sufficient expectation of the state.

  The present invention makes it difficult for a player to predict the end of a specific gaming state in which the probability of deciding to permit the derivation of a replay display result is higher than the normal gaming state, and until the specific gaming state actually ends It is an object of the present invention to provide a slot machine that can improve the interest of the game by expecting the player to continue.

To achieve the above object, a slot machine according to the present invention includes:
By setting a predetermined number of bets for one game, the game can be started, and the display result is displayed on a variable display device (variable display device 2) that variably displays a plurality of types of identification information each of which can be identified. In a slot machine in which one game is completed by being derived and winning can be generated according to the display result derived to the variable display device,
It is determined by lottery whether or not to allow the derivation of a plurality of types of winning display results including a replay display result (replay) accompanied by replay before the display result of the variable display device is derived for each game. Predetermining means for determining (step S403, FIG. 14, FIG. 20);
Fluctuation stop control means (step S405) for stopping the fluctuation display of the identification information according to the determination result of the prior determination means and deriving the display result of the variable display device,
The variable stop control means includes a specific display result accompanied by a transition of a gaming state to a specific gaming state in which a probability that the predetermining means determines to permit the derivation of the re-game display result is higher than a normal gaming state. Including specific derivation means (FIGS. 6A to 6C) for deriving (RT symbol),
Specific game state control means (step S714) for controlling the game state to the specific game state when the specific display result is derived as the display result of the variable display device;
Specific game state ending means (step S812) for ending the specific game state when the number of games digested after being controlled to the specific game state by the specific game state control means reaches a predetermined number of games. ,
Specific notification means (liquid crystal display 4) for performing a specific notification indicating that the number of remaining games until the specific gaming state ends is controlled to the specific gaming state in an unspecified manner;
Specific notification determining means (step S924) for determining that the specific notification is performed when a predetermined condition is satisfied in a game after the specific display result is derived as the display result of the variable display device; ,
On the condition that the notification is determined by the specific notification determination unit, the specific notification start unit (step S926) that causes the specific notification unit to perform the specific notification and the specific gaming state end unit Specific notification control means including specific notification end means (step S928) for causing the specific notification means to end the specific notification when the notification is terminated.

  In the slot machine, when the specific display result is derived as the display result of the variable display device, the game state is controlled to the specific game state, and the specific game state is terminated when a predetermined number of games are consumed. Here, the fact that the specific game state has been controlled is recognized when the specific display result is derived as the display result of the variable display device. However, if the specific notification determining means is determined, the specific game is determined separately. The specific notification means notifies that the state is controlled. For this reason, even when the player misses the derivation of the specific display result, it is possible to give the player a sense of expectation for being controlled to the specific game state.

  Also, if the player misses the derivation of the specific display result, the specific notification means that the game state is controlled to the specific game state by the specific notification means is performed after the specific display result is derived. This is a time when a predetermined condition is established in the game, and the specific notification is performed in such a manner that the number of remaining games until the specific gaming state ends cannot be specified. For this reason, even if the player recognizes that the specific gaming state is controlled by the start of the specific notification, the end of the specific gaming state cannot be predicted. Thereby, regardless of the number of remaining games until the end of the specific gaming state, the player can have a sense of expectation for the continuation of the specific gaming state, and the interest of the game can be improved. Note that the re-game given by deriving the re-game display result means that the next game can be played without using the game value for setting the bet amount.

  The specific display result may be a winning display result other than the winning display result that is not given any value other than the transition to the specific gaming state when the specific display result is derived as the display result of the variable display device. The stop control means may derive the specific display result when the winning display result is not derived as the display result of the variable display device. Further, the specific display result may be a prize display result to which other value (giving valuable value or granting a replay) is given in addition to the transition of the specific gaming state. As one type, the specific display result may be derived.

In the above slot machine,
In the case where the variable display device includes a plurality of variable display portions (reels 3L, 3C, 3R), each of which variably displays the plurality of types of identification information,
The specific display result is preferably configured by a combination of different types of identification information (white 7-bell-JAC) for each of the plurality of variable display units.

  Generally, in slot machines, winning display results are often composed of combinations of identification information of the same type, and when a display result of combinations of different identification information is derived, the player is given some value. There are many things that are not to be done. As described above, the specific display result is composed of a combination of different types of identification information, so that it is difficult for a player who is used to a game in a general slot machine to notice the derivation of the specific display result. The start of the specific game state is difficult to understand depending on the display result of the variable display device. If the start of the specific gaming state is not known from the display result of the variable display device, it will be difficult to predict the end of the specific gaming state, and the specific gaming state will continue regardless of the number of remaining games until the specific gaming state ends. It is possible to improve the interest of the game by giving the player a sense of expectation for the game.

The slot machine is
An effect display that is provided separately from the variable display device, is provided more easily than the variable display device, and variably displays a plurality of types of effect identification information that can be individually identified by a plurality of effect variable display units. A variable display device (virtual reel of the liquid crystal display 4);
It may further include effect variation display control means (steps S913 and S915) for causing the effect variable display device to derive the effect display result corresponding to the display result derived to the variable display device. In this case,
When the specific display result is derived as the display result of the variable display device, when the display result different from the specific display result is derived as the display result of the variable display device It is also possible to include an effect specific deriving means (step S915) for deriving the same effect specific display result (other than watermelon-watermelon-watermelon) as the effect display result that can be derived.

  In addition, the production variable display control means, when the specific display result is derived as the display result of the variable display device, the production specific display result (combination of different types of production identification information) An effect of deriving a display result of the variable display device that may be different from or the same as the effect display result that can be derived when a display result different from the specific display result is derived It may be possible to include specific derivation means.

  In this way, the same effect display result as the effect specific display result can be derived even when the specific display result is derived to the variable display device, thereby specifying the display result of the effect variable display device. It is possible to make it difficult for the player to notice the derivation of the display result. Further, it is possible to make it difficult for the player to notice the derivation of the specific display result by configuring the effect specific display result by combining different types of effect identification information and also by the display result of the effect variable display device. Furthermore, since the variable display device for production is provided so as to be more visible than the variable display device, the specific display result derived to the variable display device is temporarily reduced by making it difficult to notice the derivation of the specific display result for production. Even in the case of a combination of identification information of the same type (although not limited to such a case), it is possible to make it difficult for the player to notice the specific display result.

  In this way, it is difficult for the player to notice the derivation of the specific display result, and as a result, it becomes difficult for the player to understand the start of the specific game state. If the start of the specific gaming state is not known from the display result of the variable display device, it will be difficult to predict the end of the specific gaming state, and the specific gaming state will continue regardless of the number of remaining games until the specific gaming state ends. It is possible to improve the interest of the game by giving the player a sense of expectation for the game.

The slot machine is
When specific notification is performed by the specific notification means, the ratio varies depending on the number of digested games after the start of the specific gaming state and / or the number of remaining games until the end of the specific gaming state (see FIG. In 9), specific effect means (step S908) for performing a specific effect (bonus notice, bonus notice) indicating the determination result of the prior determination means may be further provided.

  In the slot machine, when specific notification is performed by the specific notification means, the number of digest games after the start of the specific gaming state and / or the number of remaining games until the end of the specific gaming state It is good also as a thing further provided with the specific production | presentation means which performs the specific production | presentation which shows the determination result of the said prior determination means with different production | generation aspects according to.

  In the slot machine, when specific notification is performed by the specific notification means, the number of digest games after the start of the specific gaming state and / or the number of remaining games until the end of the specific gaming state It is also possible to further include a specific effect unit that selects a specific effect mode from a plurality of types of effect modes at different ratios and performs a specific effect indicating the determination result of the prior determination unit.

  Here, the specific effect is a special display result (regular bonus, big bonus (1), big bonus) accompanied by a transition to a special gaming state advantageous to a player other than the specific gaming state in the plurality of types of winning display results. When (2)) is included, it can be an effect (bonus announcement, bonus advance notice) indicating that the advance determination means has determined that the special display result is allowed to be derived. This effect is determined not only when it is actually determined that the derivation of the special display result is permitted, but also when it is not determined that the derivation of the special display result is permitted. Can be done at a lower rate than when In addition, when the plurality of types of winning display results include a small combination display result accompanied by a valuable value that can be used for setting the number of bets, the specific effect allows the small combination display result to be derived. It is possible to make an effect (small role notification) indicating that the prior decision means has decided to do so.

  In these cases, even if it is difficult to understand the end of the specific gaming state from the information notified from the specific notification means, the frequency of the specific effects performed by the specific effect means (or the difference in the effect modes, each effect mode of the specific effects) Depending on the frequency, the end of the specific gaming state can be predicted to some extent. For this reason, not only the information on whether or not the derivation of the winning display result other than the re-game display result is determined by the specific effect performed when the game state is controlled to the specific game state, but also the specific game Since information on continuation / termination of the state is also obtained, the player's interest can be attracted to the specific performance, and the interest of the game can be improved.

The slot machine is
A stop operation means (stop buttons 12L, 12C, 12R) for instructing to stop the variable display of the identification information on the variable display device by the player's operation may be further provided. In this case,
The pre-determining unit may determine whether or not to allow a derivation of a small combination display result (watermelon) accompanied by a valuable value usable for setting the bet amount as the winning display result. here,
The variable display control means is operated by the stop operation means according to a predetermined operation procedure among a plurality of operation procedures when the advance determination means determines that the derivation of the small role display result is permitted. Further including a small role derivation means (FIG. 2, FIG. 6B) for deriving the small role display result on the condition that
The specific deriving unit is configured to display the specific display when the small role display result cannot be derived by the small role deriving unit when the prior determination unit determines that the small role display result is permitted to be derived. The result can be derived (FIG. 2, FIG. 6B).

  When it is determined that the derivation of the small role display result is permitted according to the determination result of the prior determination means, the small role display result is derived by operating the stop operation means in a predetermined procedure. A valuable value is given to the player and a profit can be obtained directly. On the other hand, even if it is determined that the derivation of the small role display result is permitted, the small role display result is not derived unless the stop operation means is operated in a predetermined procedure. Cannot benefit from value addition. However, even if the small role display result is not derived by the operation procedure of the stop operation means, the specific display result can be derived, and there is a probability that it is determined that the derivation of the replay display result is permitted in the subsequent game. Since the player can obtain the profit of becoming higher, it is not necessary to reduce the player's willingness to play.

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

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

The slot machine is
Numerical data input means (step S1003) for inputting numerical data (random numbers for internal lottery) updated within a predetermined range into a determination area predetermined as determination numerical data at a predetermined timing for each game;
A range of determination values for determining that the pre-determining means allows the derivation of a special display result with a transition to a special gaming state that is a gaming state advantageous to the player over a normal gaming state other than the specific gaming state Special range specifying data storage means (FIG. 19: bonus table) for storing special range specifying data determined so that can be specified;
A range of determination values for determining that the pre-determining means allows the derivation of a non-special display result that is a winning display result other than the special display result including the re-game display result (and the small role display result). Non-special range specifying data determined so that it can be specified for each type of winning display result, and at least a part of a range of determination values for determining that the non-special display result is derived is specified as the special range Non-special range specifying data storage means (FIG. 19: small role table) for storing non-special range specifying data included in the range of determination values specified by the data;
Special decision carry-over means (step S813) for carrying over the decision to allow the derivation of the special display result until the special display result is derived based on the decision to permit the derivation of the special display result It may be provided. here,
The pre-determining means includes
The determination numerical data is stored in the special range specifying data storage means on the condition that the decision to allow the derivation of the special display result is not carried over by the special determination carry means (step S1009 (NO)). Special determination means for determining whether or not the derivation of the special display result is allowed by determining whether or not the determination value is included in the range of the determination value specified by the specified special range specifying data (steps S1010 to S1013) When,
Regardless of whether or not the decision to allow the derivation of the special display result is carried over by the special decision carry-over unit (the determination step as in step S1009 is not performed), the prior determination unit does not include the determination numerical value. Whether to allow the derivation of the non-special display result by determining whether or not the data is included in the range of the determination value specified by the non-special range specifying data stored in the non-special range specifying data storage means Non-special determination means (steps S1004 to S1007) for determining whether or not.

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

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

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

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

In this case,
The pre-determining unit reads out data indicating the allowable level stored in the data storage unit when determining whether to permit the derivation of the winning display result, and indicates the read allowable level Permissible stage data determining means (steps S501, S502, S1001, and S1002) for determining whether or not the data is appropriate data indicating an allowable stage that can be set by the allowable stage setting means may be included. here,
The disabling means can disable the progress of the game even when the allowable stage data determination means determines that the data indicating the allowable stage read from the data storage means is not appropriate data ( Steps S502 (NO), S1002 (NO), Step S301).

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

The slot machine is
Based on the operation of predetermined setting operation means (setting key switch 92, setting switch 91), a plurality of types of permissible stages (settings) having different probabilities that the predetermination means determines to permit the derivation of the winning display result Value), an allowable stage setting means (steps S201 to S210) for selecting and setting one of the allowable stages,
Numerical data input means (steps S503 and S1003) for inputting numerical data to be updated within a predetermined range into a determination region predetermined as determination numerical data for each game at a predetermined timing is further provided. I can. In this case,
In the pre-determining means, the determination numerical data input to the determination area is included in a range of a plurality of types of determination values that are predetermined for each unit for performing determination to permit derivation. Is determined to permit the derivation of the winning display result corresponding to the range of the determination value determined to include the determination numerical data (steps S510 and S511),
Means for storing a plurality of range specifying data determined such that ranges of the plurality of types of determination values can be specified respectively, wherein the first range specifying data among the plurality of range specifying data is the plurality of types The first storage area (regular bonus + cherry, big bonus (1) + cherry, big bonus (2) + cherry, JACIN, watermelon, bell, replay) to be stored in common in the permissible stages and the plurality of ranges specified A second storage area (regular bonus, big bonus (1), big bonus (2), second bonus area (2), in which second range identification data different from the first range identification data among the data is individually stored for each type of the allowable stage. Range specifying data storage means (FIG. 6, FIG. 7) including “cherry”.

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

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

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

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

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

The slot machine is
Numerical data updated within a predetermined range is determined in advance as numerical data for determination (random number for internal lottery) at a timing corresponding to a predetermined operation (operation of the start lever 11) by the player for each game. Numerical data input means (step S503) for inputting to the area (general-purpose register 111GR) can be further provided.
The prior determination means may determine whether or not to allow the plurality of types of winning display results to be derived in accordance with the value of the determination numerical data input to the determination area. (Steps S509 and S510). Here, the slot machine is
A pulse generation circuit (pulse generation circuit 115a) for generating a pulse signal of a predetermined frequency;
An n-bit (n is an integer greater than or equal to 2) array data signal is inverted alternately between the first level and the second level every time a pulse signal is input from the pulse generation circuit, and Each time the level of the (m-1) th bit (m is an integer of 2 or more: m ≦ n) from the lower level is inverted from the first level to the second level, the level of the mth bit from the lower level is changed to the first level. A counter circuit (lower counter 115b, upper counter 115c) that alternately inverts and outputs at two levels;
When a predetermined extraction condition resulting from the player's operation is satisfied, the n-bit array data signal output from the counter circuit is latched, and the bit order of the latched n-bit array data signal is changed. A latch circuit (sampling circuit 116) that outputs without any error,
An input means (step S602) for inputting an n-bit array data signal output from the latch circuit as n-bit numerical data without changing the bit array order into a predetermined specific area (general-purpose register 111GR). It can be provided.

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

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

In the pre-determining means, the determination numerical data input to the determination area is included in a range of a plurality of types of determination values that are predetermined for each unit for performing determination to permit derivation. It is possible to determine that the winning display result corresponding to the range of the determination value determined to include the determination numerical data is permitted.

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

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

It is possible to determine that the winning display result corresponding to the range of the determination value determined to include the determination numerical data is permitted.

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

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

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

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

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

  The effect control board 102 is a sub-side control board that controls the execution of effects in the slot machine 1, and is equipped with a control unit 120 including a one-chip microcomputer including a CPU 121, a RAM 122, a ROM 123, and an I / O port 124.

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

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

The reel relay substrate 103 is also connected with a full sensor 90, and its detection signal is input. The full tank sensor 90 is provided inside the slot machine 1 and detects that the medals in the overflow tank storing the medals overflowed from the hopper 80 are full.

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

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

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

  In the slot machine 1, the medal payout rate changes according to the set value, and the winning probability of the internal lottery described later is determined according to the set value. Hereinafter, a setting value changing operation using the setting switch 91 will be described. In order to change the setting value, it is necessary to turn on the power of the slot machine 1 by the main switch 94 after the setting key switch 92 is turned on. When the slot machine 1 is started without changing the setting value, the setting key switch 92 may be turned off and the power may be turned on by the main switch 94.

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

  When the game can be progressed, the games in the slot machine 1 progress one game at a time, but the set value stored in the set value work 112-4 in the internal lottery performed in each game is within the normal range (1 -6) is determined. When the set value is not within the normal range, it is determined that the RAM is abnormal, and a RAM abnormal error code is set and controlled to a RAM abnormal error state to disable the progress of the game.

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

  When the control unit 110 of the game control board 101 is activated, the RAM parity is calculated based on all data other than the data stored in the parity storage area 112-7 among the data stored in the RAM 112. Compared with the RAM parity stored in the parity storage area 112-7. If the comparison results match, the state before power-off is restored based on the state stored in the RAM 112.

  On the other hand, if the comparison result of the RAM parity does not match, it is determined that the RAM is abnormal again, and the RAM abnormal error code is set to control the RAM abnormal error state, thereby making the progress of the game impossible. ing. Unlike the other error states, the RAM abnormal error state is not canceled even if the first reset switch 48 or the second reset switch 93 is operated, and a new set value is set in the setting change mode. It comes to be canceled by this.

  In the slot machine 1, a winning is awarded when the symbols are arranged on any of the active lines of the variable display device 2. The types of winning combinations are determined according to the gaming status, but can be broadly divided into special roles that involve the transition of gaming status, small roles that involve the payout of medals, and no need to set the number of bets. There is a re-player who can start the next game. FIG. 6A is a diagram for explaining the combination of the types of winning combinations in the slot machine 1 and the symbols in the variable display device 2.

  The regular bonus is awarded when a combination of “red 7-white 7-blue 7” is aligned on any of the active lines (eight) in the normal gaming state or RT. When the regular bonus is won, the gaming state shifts from the normal gaming state to the regular bonus. The regular bonus ends when 12 games are consumed, or when 8 games are won (any kind of combination is possible), whichever comes first. While the game state is in the regular bonus, the regular bonus medium flag is set in the RAM 112 (including the case where it is provided during the big bonus described below).

  The big bonus (1) is won when a combination of “red 7-white 7-white 7” is arranged in any of the active lines (eight) in the normal gaming state or RT. The big bonus (2) is awarded when a combination of “red 7-blue 7-blue 7” is aligned on either of the active lines (eight) in the normal gaming state or RT. When the big bonus (1) or the big bonus (2) is won, the gaming state shifts to the big bonus. In the big bonus, a game called a small role game can be played. While the gaming state is the big bonus, the big bonus medium flag is set in the RAM 112. The big bonus ends when the number of medals paid out to the player exceeds 465. Here, since the maximum payout number per game is 15, the upper limit of the payout medal number in the big bonus is 480.

  When a regular bonus, a big bonus (1), and a big bonus (2) are won in an internal lottery to be described later, since “red 7” is arranged at intervals of 7 frames for the left reel 3L, the stop button 12L Regardless of the operation timing, “Red 7” can be stopped at the upper or lower level. However, because there are places where the arrangement interval of “white 7” and the arrangement interval of “blue 7” exceed 7 frames for the middle and right reels 3C and 3R, the stop buttons 12C and 12R are operated at a predetermined timing. Otherwise, “blue 7” or “white 7” may not be stopped at the upper or lower level.

  JACIN is awarded when a combination of “Bell-Cherry-Cherry” is placed on any of the active lines (eight) in the small role game in the big bonus, but in a game state other than the small role game, Even if the combination is complete, JACIN won't win. When winning JACIN, the above-mentioned regular bonus is provided in the big bonus, and the regular bonus medium flag is also set in the RAM 112 in addition to the big bonus medium flag. The “bell” for the left reel 3L and the “cherry” for the middle and right reels 3C, 3R are all arranged at intervals of 7 frames or less, so when you win JACIN in the internal lottery described later, be sure to JACIN won a prize.

  The watermelon is awarded when the combination of “blue 7-bell-JAC” is aligned on any of the active lines (eight) in any gaming state, and 5 medals are paid out. The “bell” for the inner reel 3C and the “JAC” for the right reel 3R are always arranged within 7 frames, whereas the “blue 7” for the left reel 3L has an arrangement interval of 7 frames. There are also places to exceed. For this reason, even if the watermelon is won in the internal lottery described later, the watermelon cannot be won if the stop button 12L is not operated at a predetermined timing.

  However, considering “blue 7” or “white 7”, the arrangement interval on the left reel 3L is 7 frames at a time, so that when the watermelon is selected, the left reel 3L When “blue 7” cannot be stopped at the upper stage or the lower stage, “white 7” is stopped at the upper stage or the lower stage. In the normal gaming state, when a combination of “White 7-Bell-JAC” is aligned on any of the active lines (eight) due to such a watermelon omission, RT will be awarded and between the next game and 100 games Only the gaming state is controlled to RT. In other than the normal gaming state (RT, big bonus, regular bonus), even if a combination of “White 7-Bell-JAC” is prepared due to a watermelon failure, no RT prize is awarded. Note that RT winning is not defined as a winning role, but here it is called RT “winning” in order to distinguish it from a complete loss where the player cannot obtain any profit. It is supposed to be.

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

  Replays are awarded when the combination of “Red 7-JAC-Cherry” is placed on either of the active lines (eight) in the normal gaming state or RT, but regular bonuses and big bonuses (small game and Regular bonus) will not be replayed even if this combination is available. When a replay is won, the medal will not be paid out, but the next game can be started without setting the bet number again, so the number of bets that became unnecessary in the next game (the regular bonus will not be replayed and will always be 3) This is substantially the same as when three corresponding medals are paid out.

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

  FIG. 6B 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 the game state is a small-bonus game with a big bonus, regular bonus + cherry, big bonus (1) + cherry, big bonus (2) + cherry, JACIN, watermelon, bell, cherry Read out.

  In normal gaming state, regular bonus + cherry, regular bonus, big bonus (1) + cherry, big bonus (1), big bonus (2) + cherry, big bonus (2), watermelon, bell, cherry, Normal time replays are sequentially read out as a target for internal lottery. When the game state is RT, regular bonus + cherry, regular bonus, big bonus (1) + cherry, big bonus (1), big bonus (2) + cherry, big bonus (2), watermelon, bell, cherry, RT replays are sequentially read out as a target combination for internal lottery. The normal-time replay and the RT-time replay have different winning probabilities because the storage areas for the number of determination values described later are different, but the other points are common.

  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. 6C is a diagram illustrating an example of the role-specific table. The number of determination values may be 256 or more, and cannot be stored for one word. Therefore, each determination value is registered using a storage area for two words.

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

  Regular Bonus + Cherry, Big Bonus (1) + Cherry is a small role game, a normal game state or a role that is subject to internal lottery in RT, and the number of bets in the small role game, normal game state or RT is 3 The storage address of the number of judgment values corresponding to is registered. 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 the roles that are subject to the internal lottery in the normal gaming state or RT, and the judgment values corresponding to the betting number 3 in the normal gaming state or RT. A number of storage addresses are registered. For these combinations, the value of the common flag is 0, and the storage address for the number of determination values is individually registered according to the set value. JACIN is an internal lottery target only in the small bonus game in the big bonus, and a storage address for the number of determination values corresponding to the bet number 3 in the small bonus game is registered. The value of the common flag for this role is 1, and a storage address for a common number of determination values is registered regardless of the set value.

  The normal time replay is a combination that is subject to internal lottery only in the normal gaming state, and the storage address of the number of determination values corresponding to the bet number 3 in the normal gaming state is registered. The common flag for this combination is 1, and a common storage address for the number of determination values is registered regardless of the set value. The RT replay is an internal lottery target only in RT, and a storage address of the number of determination values corresponding to the betting number 3 in the normal gaming state is registered. The common flag for this combination is 1, and a common storage address for the number of determination values is registered regardless of the set value.

  Watermelons, bells and cherries are internal lotteries in any gaming state, the storage address of the number of judgment values corresponding to the number of bets 1 with regular bonus, normal gaming state, RT or small role game The storage address of the number of determination values corresponding to the betting number 3 is registered. 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.

  FIG. 7 is a diagram illustrating a storage area for the number of determination values acquired based on 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 referenced when the number of bets is 3, that is, a small-combination game, a normal gaming state, an internal lottery target is a regular bonus + cherry in RT, and a set value is 1-6. is there. The address ADD + 14 is an address that is referred to when the bet number is 3, that is, a small role game, a normal gaming state, and an internal lottery target character is a big bonus (1) + cherry and a set value is 1-6. It is. The address ADD + 28 is an address that is referred to when the bet number is 3, that is, a small role game, a normal gaming state, and an internal lottery target is a big bonus (2) + cherry and a set value is 1-6. It is.

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

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

  The address ADD + 42 is an address that is referred to regardless of the set value when the subject combination of the internal lottery is JACIN, and 4431 is acquired as the number of determination values regardless of the set value. The address ADD + 44 is an address that is referred to when the bet number is 3, that is, a small-combination game, a normal gaming state, and a target combination of internal lottery is a watermelon in RT and a set value is 1-6. The address ADD + 46 is an address that is referred to when the number of bets is 1, that is, in the regular bonus, when the target part of the internal lottery is a watermelon and the set value is 1-6.

  The address ADD + 48 is an address that is referred to regardless of the set value when the number of bets is 3, that is, when the small lottery game, the normal gaming state, and the target lottery of the internal lottery in the RT is a bell. The address ADD + 50 is an address that is referred to regardless of the set value when the number of bets is 1, that is, in the regular bonus, when the target part of the internal lottery is a bell. Since the number of judgment values for the bell is different depending on the number of bets, the value of the bell is different depending on whether the gaming state is in the regular bonus, the small role game, the normal gaming state, or the RT. Winning probabilities will be different.

  Addresses ADD + 52, ADD + 54, ADD + 56, ADD + 58, ADD + 60, and ADD + 62 each have a bet number of 3, that is, a small-combination game, a normal gaming state, and a target value for internal lottery in RT and a set value of 1 to 6 This is the address that is referenced when The addresses ADD + 64, ADD + 66, ADD + 68, ADD + 70, ADD + 72, and ADD + 74 are addresses that are referred to when the bet number is 1, that is, when the target character of the internal lottery is cherry and the set value is 1 to 6 in the regular bonus. is there. Here, the number of determination values when the bet number is 3 is 60 less than the determination value number when the bet number is 1 for each set value, regular bonus + cherry, big bonus (1) + cherry, big bonus (2) Since the number of determination values of + cherries is 20, respectively, the winning probability of cherries is the same in any gaming state, including the case of overlapping winning.

  The address ADD + 76 is an address that is referred to when the target part of the internal lottery is replay (in this case, normal replay) and the set value is 1 to 6 in the normal gaming state. The address ADD + 78 is an address that is referred to when the target part of the internal lottery is replay (here, replay at RT) and the set value is 1 to 6 in RT. Since a value larger than the address ADD + 76 is registered in the address ADD + 78, the replay winning probability in RT is higher than the replay winning probability in the normal gaming state.

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

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

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

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

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

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

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

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

  FIG. 8B is an explanatory diagram until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. The random number extracted from the random number generation circuit 115 is stored in a 16-bit general-purpose register 111GR included in the CPU 111.

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

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

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

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

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

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

  For example, on the active line set on a straight line (for example, the horizontal direction and the diagonal direction in the upper, middle, and lower stages), the symbols constituting the winning display mode by the time the second reel is stopped are displayed as the tempered (that is, the third reel). Even if the winning display mode is derived on the active line (except for), in order to win the winning combination, the symbol of the winning position is positioned on the active line that is tempered, or the position If the stop button is not operated when there is a symbol for the role within the next 4 frames, no winning will be won.

  On the other hand, in the slot machine 1 according to this embodiment, the effective line of the variable display device 2 is constituted by a combination of the upper or lower stage of each reel as shown in FIG. For this reason, in order to derive the winning display mode, in order to win the winning combination set in the winning flag, it is only necessary to stop the symbol of the winning combination in either the upper row or the lower row. When the symbols that make up the display mode are tempered, the symbols that make up the role are located in the lower row, or within the next six frames from the lower row (because it can be stopped in the upper row if there are six frames ahead) If the stop button is operated when there is a symbol for a winning combination, a prize will be won.

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

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

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

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

  Next, commands that the CPU 111 of the game control board 101 transmits to the effect control board 102 will be described. The CPU 111 sends various commands according to the progress of each game, but a winning status notification sent after the internal lottery is performed as a command necessary for performing the effects described in this embodiment. Command, reel rotation command sent when the rotation of the reels 3L, 3C, and 3R starts, reel stop command sent when the rotation of the reels 3L, 3C, and 3R stops, and the display result is derived to the variable display device 2. There is a winning information command sent after being played, and a gaming state command sent after the end of one game and before shifting to the next game.

  The winning status notification command indicates the setting status of the winning flag in the RAM 112. The reel rotation command indicates the start of reel rotation. The reel stop command indicates the type of reel that has been stopped and the derived symbol. The winning information command indicates the presence / absence of a winning and the type of winning. The game state command indicates a game state (normal, RT, regular bonus, big bonus) applied in the next game. The gaming state command indicates different information depending on whether the remaining number of games is 20 games or more or less than 20 games when the gaming state is RT.

  The CPU 121 of the effect control board 102 performs various effects based on the commands sent from the CPU 111 of the game control board 101 as described above. As an effect executed by the control of the CPU 121, particularly as an effect performed on the liquid crystal display 4, an effect of deriving a display mode corresponding to a symbol derived to the variable display device 2 by a change / stop of the virtual reel, and a game There is a notice that the state is in RT, a regular bonus, a big bonus (1) or a big bonus (2) winning announcement and notice.

  For example, the reels 3L, 3C, and 3R of the variable display device 2 are virtual reels in which symbols such as “BAR”, “7”, “JAC”, “watermelon”, “bell”, and “cherry” are arranged in a predetermined arrangement. Three are displayed corresponding to. Each of “BAR” and “7” includes “watermelon” and “bell” in the arrangement that allows double tempering. The virtual reels start to change when the reels 3L, 3C, and 3R start to rotate, and stop changing when the reels 3L, 3C, and 3R stop rotating. However, the stop of the virtual reel is not limited by the maximum stop delay time of 190 milliseconds like the reels 3L, 3C, and 3R of the variable display device 2.

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

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

  Further, when winning the bell, “bell” is aligned on the effective line of the virtual reel. In this case as well, the symbols to be derived can be determined in advance since they are not missed unless they are in the case of double winning with the regular bonus, the big bonus (1) or the big bonus (2). Even in the case of a winning combination with the regular bonus, the big bonus (1) or the big bonus (2), the virtual reel may be controlled to stop until the second reel so that “BAR” or “7” and “Bell” are double-tempered. . When winning a cherry, “cherry” is led to the left virtual reel.

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

  Furthermore, when a watermelon is won according to the display result of the variable display device 2, “watermelon” is aligned on the effective line of the virtual reel. Here, in the case where the regular bonus, the big bonus (1) or the big bonus (2) are not overlapped, if the watermelon is dropped by the operation timing of the stop button 12L, the RT symbol is derived to the variable display device 2. . At this time, a display mode of “other than watermelon-watermelon-watermelon” is derived on any effective line of the virtual reel.

  However, the display mode of “non-watermelon-watermelon-watermelon” is a display mode that can be derived even when the display mode of losing is derived in the variable display device 2 without winning the watermelon in the first place. Above, when the display mode of "other than watermelon-watermelon-watermelon" is derived to the virtual reel, the display mode of the loss is mostly derived to the variable display device 2, and the RT symbol is variably displayed by dropping the watermelon. Less when led out to the device 2.

  By the way, if you win regular bonus, big bonus (1), big bonus (2) and bells other than watermelon, cherries, and replays in normal gaming state or RT, you will be allowed to win these roles without missing them. Can do. In the first place, the watermelon has a low winning probability itself, and even if it is missed in a normal gaming state, it will be controlled by RT. Therefore, in RT, the player pushes the operation of the stop buttons 12L, 12C, and 12R (the stop operation is performed at a timing according to the symbols displayed on the rotating reels 3L, 3C, and 3R). There is almost no need. The regular bonus, the big bonus (1), or the big bonus (2) needs to be pressed. In this case, it is sufficient to perform the pressing when a bonus announcement or bonus notice described later is made.

  As long as there is no need to push the game, the player only needs to know what role he has won as a result, so that even if he only looks at the virtual reel, the game can proceed sufficiently. Become. The display mode of “non-watermelon-watermelon-watermelon” on the virtual reel is a display mode that is also derived at the time of deriving the RT symbol, but in practice it is more often derived when losing, Even if the display mode of “watermelon-watermelon” is derived to the virtual reel, it is easy for the player to miss the derivation of the RT symbol in the variable display device 2.

  Further, even if the player views the variable display device 2 when the display mode of “other than watermelon-watermelon-watermelon” is derived to the virtual reel, the same type of symbols are arranged side by side on the variable display device 2. Since it is not, it is easy for a player to miss the RT symbol derivation. Moreover, when the RT symbol is derived to the variable display device 2, unlike the other winning combinations, there is no sound output from the speakers 7L and 7R and no light emission from the game effect display units 5A to 5E. It is easy for the player to miss the RT symbol derivation in the device 2.

  Next, notification that the gaming state is at RT will be described. As described above, the gaming state is controlled to RT based on the RT symbol being derived to the variable display device 2, but at this timing, there is no notification that the gaming state is at RT. In each game when the gaming state is controlled to RT, an RT notification lottery is performed, and the fact that the gaming state is at RT is notified on the liquid crystal display 4 only after winning the lottery. The notification that the gaming state is RT is continuously performed after winning the RT notification lottery until the RT is completed, but during this time, information that can specify the number of remaining RT games is notified. There is no.

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

  When the game state is a big bonus or a regular bonus, the regular bonus, the big bonus (1), or the big bonus (2) is not won in the first place, so no bonus announcement or bonus notice is performed. Even in the normal gaming state or RT, once the bonus notification is made, no further bonus notification or bonus notice is performed. The bonus / notice decision random number (0 to 1023) is used to determine whether or not to give a bonus notice or bonus notice when a bonus notice has not yet been made in the normal gaming state or RT. Is determined with reference to the bonus notification / notice determination table.

  FIG. 9 is a diagram showing a bonus notification / notice determination table. The determination of the bonus notification or the bonus advance notice is performed according to whether or not a notification that the gaming state is RT is performed and the number of remaining RT games. In the normal gaming state, there is no notification that the gaming state is RT, so that the bonus notification or bonus notice is the same as when the gaming state is controlled by RT but that is not notified. A decision will be made.

  However, the regular bonus, the big bonus (1) or the big bonus (2) is not won at the same time as the watermelon, bell or replay. If you lost a watermelon, bell, or replay and you lost in the previous game, you will not win the regular bonus, big bonus (1), or big bonus (2) even if the bonus notice is given Is predicted. Accordingly, the bonus notice may be determined on the condition that the watermelon, bell or replay is not won. Further, it may be determined that the bonus advance notice is made on the condition that the replay derived in preference to the regular bonus, the big bonus (1) or the big bonus (2) is not won.

  As shown in FIG. 9, when the game state is informed at RT and the remaining RT game count is 20 games or more, the frequency is twice as high as when the game state is not informed at RT. Bonus notice and bonus notice A are performed, and bonus notice B is performed four times as often. Also, when it is notified that the gaming state is RT and the number of remaining RT games is less than 20 games, the bonus notification and bonus notice A are doubled compared to when the remaining RT game count is 20 or more. However, the bonus notice B is performed at a half frequency. The reliability of bonus notice A and bonus notice B (the ratio of winning the regular bonus, the big bonus (1) or the big bonus (2) when the notice is made) is the same.

  Further, the bonus notice C may be performed only when the fact that the gaming state is in RT is notified and the number of remaining RT games is less than 20 games. Bonus notice C is made with a probability of 256/1024 when the regular bonus, the big bonus (1) or the big bonus (2) is won, but only with a frequency of 1/1024 when these are not won. Since it is not performed, the reliability is much higher than that of bonus notice A and bonus notice B.

  In addition, the notification that the gaming state is in RT, the bonus notification (except for the one by the bonus notification unit 36), and the bonus advance notice are displayed together with the change display of the effect design by the virtual reel in a manner that does not disturb the visual recognition of the virtual reel. This is performed in the liquid crystal display 4. In addition, in order to enable the CPU 121 of the effect control board 102 to determine that the notification that the gaming state is at RT, the bonus notification, or the bonus notice is being performed, the gaming state is in the RAM 122. An area for setting an RT notification flag indicating that the effect has been notified, a notification flag indicating that the bonus notification is being performed, and a notification flag indicating that the bonus notification is being performed is provided. The RAM 122 also displays the winning status of each combination indicated by the winning status notification command received from the game control board 101, the symbols derived to the reels 3L, 3C, and 3R indicated by the reel stop command, and the gaming status indicated by the gaming status command. An area for storage is also provided.

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

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

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

  Next, the RAM parity calculated here is compared with the RAM parity stored in the parity storage area 112-7, that is, the RAM parity calculated and stored at the previous power-off (step S105). Whether or not the data stored in the RAM is normal (step S106). In this embodiment, whether or not the RAM 112 is normal based on the RAM parity is determined only in the startup process.

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

  If the setting key switch 92 is ON in step S103, all the data stored in the RAM 112 is initialized except for the area in use in the stack area 112-6 (other than the setting value work 112-4). Is rewritten to 0 and the set value work 112-4 is rewritten to 0) (step S109), the prohibition of interruption is canceled (step S110), and the process proceeds to the setting change process shown in FIG. 11 (step S111). Then, after the setting change process is completed, the game can be progressed and the process proceeds to the game control process.

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

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

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

  FIG. 12 is a flowchart showing in detail the RAM abnormality error process executed by the CPU 111 of the game control board 101. In the RAM abnormality error process, the payout display 51 is controlled to display the RAM abnormality error code on the payout display unit 21 (step S301), and then the process proceeds to a loop process in which no process is performed.

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

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

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

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

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

  Next, the number of bets is set by operating one BET button 14 or MAXBET button 15 or by inserting medals from the medal insertion slot 13, and operating the start lever 11 to substantially change the game. BET processing for instructing start is performed (step S402). Here, when the gaming state is a regular bonus (including that provided during the big bonus), if the bet number is set to 1 (the bet number larger than this is not set), the start lever 11 is activated. Become. In other game states, the start lever 11 becomes effective after 3 is set as the bet number. Further, if the player has won a replay in the previous game, the same bet number (3 in this embodiment) as the previous game is automatically set by the replay game flag (the replay game flag is erased at this stage). The start lever 11 becomes effective as it is.

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

  When the lottery process is completed, a reel fluctuation start process is performed (step S404). In the reel fluctuation start process, the reels 3L, 3C, and 3R in the previous game are processed on the condition that a predetermined time (for example, 4.1 seconds) has elapsed from the start of rotation of the reels 3L, 3C, and 3R. The motors 3ML, 3MC, and 3MR are driven to start rotation of all the left, middle, and right reels 3L, 3C, and 3R. When starting the rotation of the reels 3L, 3C, 3R, a reel rotation command is transmitted to the effect control board 102. As a result, as the symbols are variably displayed on the variable display device 2, the effect symbols are variably displayed on the virtual reel of the liquid crystal display 4.

  Here, if the predetermined time has not elapsed since the start of rotation in the previous game, the process waits for rotation to start. Also, the timing of one game timer for the next game is started. Further, when a predetermined condition (detection of the reference position by the reel sensors 3SL, 3SC, 3SR after the rotation speed reaches a constant speed) is satisfied from the start of the rotation of the reels 3L, 3C, 3R, the reel fluctuation stop process is performed. Transition.

  Thereafter, reel fluctuation stop processing is performed (step S405). In the reel fluctuation stop processing, the stop buttons 12L, 12C, and 12R are validated and operated by the player, respectively, and the reel motors 3ML, 3MC, and 3MR are driven and stopped according to the setting state of the winning flag, and the reel 3L The rotation of 3C and 3R is stopped. When the rotation of the reels 3L, 3C, 3R is stopped, a reel stop command indicating the type of the stopped reels and the stopped symbols is sent to the effect control board 102 to stop the virtual reels.

  When the driving of each of the reels 3L, 3C, 3R is stopped, in the display mode at the time of stopping, whether any of the above-mentioned role symbols is derived and displayed on the active 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 S406). 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 S407). In the payout process, the credit is increased by the number of payouts set in the winning determination process. However, when the number of credits accumulated as data reaches 50, the hopper motor 82 is driven to pay out an excess number of medals from the medal payout slot 71. In addition, various processes that are not related to winning (for example, a process related to the end control of the big bonus and the deletion of a winning flag that does not carry over) are also performed. At the end of the payout process, that is, at the end of one game, a game state command indicating the game state of the next game is sent to the effect control board 102. Details of the payout process will be described later. Then, the process for one game ends, and the process for the next one game starts.

  Next, the lottery process in step S403 will be described in detail. FIG. 14 is a flowchart showing in detail the lottery process executed by the CPU 111 in step S403. In the lottery process, the set value stored in the set value work 112-4 of the RAM 112 is read (step S501), and it is determined whether or not the read set value is in the range of 1 to 6 that is a value that should be originally taken. (Step S502). If the read set value is not in the range of 1 to 6, a RAM abnormality error occurs and the RAM abnormality error process shown in FIG. 12 is performed.

  If the read set value is in the range of 1 to 6, random number acquisition processing is performed, and a sampling command is output to cause the sampling circuit 116 to extract the random number generated by the random number generation circuit 115. The random numbers for lottery are processed into random numbers for storage in the internal random number storage area of the RAM 112 (step S503). Details of the random number acquisition process will be described later.

  Next, corresponding to the current gaming state, the lottery target combination registered in the winning combination table according to gaming state in FIG. 6B is sequentially read (step S504). Next, the number of BETs set in the current game is read, and the setting status of the common flag in the role-specific table of FIG. 6C is acquired corresponding to the number of BETs read for the lottery target (step) S505). As a result, it is determined whether the common flag is set (step S506).

  If the common flag is set, the number of determination values stored in the address registered in the role-specific table of FIG. 6C is acquired corresponding to the number of BETs for the lottery object to be read (step) S507). Then, the process proceeds to step S509. If the common flag is not set, the setting value set in the RAM 112 is read out and stored in the address registered in the role-specific table corresponding to the BET number and the read setting value for the lottery target role. The number of determination values that are present is acquired (step S508). Then, the process proceeds to step S509.

  In step S509, the number of determination values acquired in step S507 or S508 is added to the internal lottery random number value stored in the determination area of the RAM 112, and the addition result is used as a new internal lottery random value. Here, it is determined whether or not an overflow has occurred when the number of determination values is added to the value of the random number for internal lottery (step S510).

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

  If an overflow occurs, it is determined whether or not the lottery target combination read in the previous step S504 is any of regular bonus + cherry, big bonus (1) + cherry or big bonus (2) + cherry ( Step S512). If it is one of regular bonus + cherry, big bonus (1) + cherry or big bonus (2) + cherry, this means that the number of bets was 3, and at least the gaming state in this game is It is not a regular bonus (including when offered during a big bonus).

  Here, first, it is determined whether or not the current gaming state is a small role game (step S513). If it is not during the small role game, it is determined whether the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is set in the RAM 112 (step S514). If none of the regular bonus winning flag, big bonus (1) winning flag and big bonus (2) winning flag is set, the regular bonus winning flag, big bonus (1) winning flag or The big bonus (2) winning flag is set in the RAM 112, and the cherry winning flag is set in the RAM 112 (step S515). Then, the process proceeds to step S520.

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

  In step S512, if the lottery target is neither regular bonus + cherry, big bonus (1) + cherry or big bonus (2) + cherry, the lottery target is regular bonus, big bonus (1) or big It is determined whether the bonus is (2) (step S517). When the regular bonus, the big bonus (1), or the big bonus (2) is selected, the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is set in the RAM 112. It is determined whether or not (step S518).

  If any of the regular bonus winning flag, the big bonus (1) winning flag, and the big bonus (2) winning flag is set, the process directly proceeds to step S520. In step S517, whether the lottery is a regular bonus, a big bonus (1), or a big bonus (2), a regular bonus winning flag, a big bonus (1) winning flag, and a big bonus (2) winning flag in step S518 If neither of these is set, the winning flag of the lottery object combination is set in the RAM 112 (step S519). Then, the process proceeds to step S520.

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

  Next, the random number acquisition process in step S503 will be described in detail. FIG. 14 is a flowchart showing in detail the random number acquisition process executed by the CPU 111 in step S503. In the random number acquisition process, first, an interrupt to the CPU 111 is prohibited (step S601). Next, a sampling command is output to the sampling circuit 116, the random number generated by the random number generation circuit 115 is latched, and the value of the latched random number is input from the I / O port 114 and extracted. The random number value extracted from the random number generation circuit 115 is stored in the general-purpose register 111GR (step S602).

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

  Next, the winning determination process in step S406 will be described in detail. FIG. 16 is a flowchart showing in detail the winning determination process executed by the CPU 111 in step S406. In the winning determination process, winning combinations corresponding to the gaming state are read in order from the beginning (step S701). Next, it is determined whether or not the symbol combination of the read combination is aligned with any of the eight effective lines of the variable display device 2 (step S702).

  If the symbol combination of the combination is complete, a winning flag for the combination is set in the RAM 112 (step S703), and the process proceeds to step S704. If the symbol combination of the combination is not complete, the process proceeds to step S704 as it is. If RT symbols are available in the normal gaming state, the RT winning flag will be set in the RAM 112. However, if the RT symbols are available but in other gaming states, the RT winning flag is set. Never happen.

  In step S704, it is determined whether or not there is a combination that has not yet been determined as a winning determination among the combinations according to the gaming state. If there is a winning combination that has not yet been determined for winning, the process returns to step S701, and the next winning combination corresponding to the gaming state is read out.

  If all of the winning combinations corresponding to the gaming state are targeted for winning determination, it is next determined whether or not a replay winning is made based on whether or not a replay winning flag is set in the RAM 112 (step S705). If a replay prize has been won, a replay game flag is set in the RAM 112 (step S706). 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 S715.

  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 RAM 112 (step S707). If the big bonus (1) has been won, the big bonus medium flag is set in the RAM 112 and the big bonus (1) winning flag set in the RAM 112 is erased. Further, the RT counter value of the RAM 112 is initialized to 0 (step S708). Then, the process proceeds to step S715.

  If the big bonus (1) has not been won, it is determined whether or not the big bonus (2) has been won depending on whether or not the big bonus (2) winning flag is set in the RAM 112 (step S709). If the big bonus (2) is won, the big bonus medium flag is set in the RAM 112 and the big bonus (2) winning flag set in the RAM 112 is deleted. Further, the RT counter value of the RAM 112 is initialized to 0 (step S710). Then, the process proceeds to step S715.

  If the big bonus (2) has not been won, whether or not the regular bonus has been won is determined based on whether or not the regular bonus winning flag is set in the RAM 112 (step S711). If the regular bonus is won, the regular bonus medium flag is set in the RAM 112 and the regular bonus winning flag set in the RAM 112 is erased. Further, the RT counter value of the RAM 112 is initialized to 0 (step S712). Then, the process proceeds to step S715.

  If the regular bonus has not been won, it is determined whether or not the RT winning flag is set in the RAM 112 (step S713). If RT is won, 101 is set as the initial value of the RT counter in the RAM 112. Here, to set 101 as the initial value, the RT counter value is decremented by 1 in step S812 (described later) until the next game is started. This is to secure 100 games (step S714). Then, the process proceeds to step S715. If no RT winning is made, the process proceeds to step S715 as it is.

  In step S715, winning information indicating the type of winning combination based on the winning flag set in the RAM 112 (however, in the case of losing, the winning flag is not set) and the number of medals to be paid out with the winning. A command is generated and transmitted to the effect control board 102. Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  Next, the payout process in step S407 described above will be described in detail. FIG. 17 is a flowchart showing in detail the payout process executed by the CPU 111 in step S407. In the payout process, it is determined whether or not there is a small winning combination accompanied by a medal payout depending on whether or not any of the watermelon, bell, and cherry winning flags is set in the RAM 112 (step S801). If the small role is not won, the process proceeds to step S803 as it is.

  If the small role winning is achieved, the number of medals is sequentially paid out by controlling the hopper 80. However, until the number of credits accumulated as data reaches 50, instead of paying out medals, the number of credits is increased (step S802). Then, the process proceeds to step S803.

  In step S803, it is determined whether or not the game state of the game is a big bonus depending on whether or not the big bonus flag is set in the RAM 112. However, when the big bonus (1) or big bonus (2) winning flag is set in the RAM 112, it is a big bonus (1) winning or a big bonus (2) winning in the game, and the game Since the game state is not a big bonus, even if the big bonus medium flag is set, it is not determined that the big bonus is being performed. If the game state of the game is not a big bonus, the process proceeds to step S807.

  If it is determined that the big bonus is in progress, the counter provided in the RAM 112 counts the total number of medals paid out after the big bonus starts (step S804). As a result of this count, it is determined whether or not the total number of medals paid out exceeds 465 (step S805). If the total number of medals paid out does not exceed 465, the process proceeds to step S807.

  When the total number of paid-out medals exceeds 465, the big bonus medium flag set in the RAM 112 is erased, and the counter value for counting the total number of paid-out medals is initialized to 0 (step S806). ). Then, the process proceeds to step S810.

  In step S807, it is determined whether the game state of the game is a regular bonus (including a case where a big bonus is provided) based on whether or not the regular bonus flag is set in the RAM 112. However, if the regular bonus or JACIN winning flag is set in the RAM 112, it is a regular bonus winning or JACIN winning in the game, and the game state of the game is not a regular bonus. Even if the regular bonus flag is set, it is not determined that the regular bonus was in effect.

  If the game state of the game is a regular bonus, the counter provided in the RAM 112 starts the regular bonus (after a new regular bonus starts in the big bonus) The number of digested games and the number of winning games are counted (step S808). As a result of this count, it is determined whether the number of winning games in the regular bonus has reached 8 or the number of digest games in the regular bonus has reached 12 (step S809).

  If the number of winning games in the regular bonus is 8 or the number of digested games in the regular bonus is 12, the process proceeds to step S810. If the number of winning games in the regular bonus is not eight and the number of digest games in the regular bonus is not twelve, the process proceeds to step S813. In step S810, the regular bonus flag set in the RAM 112 is erased, and the counter values for counting the number of digest games and the number of winning games in the regular bonus are both initialized to zero. Then, the process proceeds to step S813.

  If the game state of the game is not a regular bonus in step S807, it is determined whether the RT counter value in the RAM 112 is 0 (step S811). If the RT counter value is 0, the process proceeds to step S813. If the RT counter value is not 0, the RT counter value is decremented by 1 (step S812), and the process proceeds to step S813.

  In step S813, if a watermelon winning flag, a bell winning flag, a cherry winning flag, a replay winning flag, and a JACIN winning flag are set in the RAM 112, these are deleted. The big bonus (1) winning flag, the big bonus (2) winning flag, and the regular bonus winning flag are not erased here and are carried over to the next game. If a winning flag is set in the RAM 112 in step S703, it is deleted.

  Next, based on the big bonus medium flag and the regular bonus medium flag in the RAM 112 and the value of the RT counter, a game state command indicating a game state applied in the next game is generated and transmitted to the effect control board 102. (Step S814). Then, the payout process is terminated, and the process returns to the flowchart of FIG. Here, when returning to the flowchart of FIG. 13, the process in the current one game ends.

  In the repetition of the game as described above, the CPU 111 of the game control board 101 shifts the game state among the normal game state, RT, big bonus, and regular bonus, and issues a command according to the progress of the game. It is transmitted to the production control board 102. On the other hand, the CPU 121 of the effect control board 102 performs a unique effect including a notification that the game state is controlled to RT, a bonus notice, and a bonus notice based on a command received from the game control board 101. Is going. Hereinafter, the process of the effect performed by the control on the effect control board 102 side will be described.

  FIG. 18 is a flowchart showing processing executed by the CPU 121 of the effect control board 102. On the side of the effect control board 102, it is determined whether or not a command sent from the game control board 101 has been received (step S901). When any command is received from the game control board 101, the type of the received command is determined (step S902).

  If the received command type is the winning status notification command transmitted in step S520, the setting status of the winning flag indicated by the received winning status notification command is further stored in a predetermined area of the RAM 122 (step S903). ). Next, it is determined whether or not the gaming state saved in the RAM 122 in the previous game (that is, the gaming state in the current game) indicates a big bonus or a regular bonus (step S904).

  If neither the big bonus nor the regular bonus exists, it is determined whether or not a bonus notification has already been made based on whether or not a notification flag is set in the RAM 122 (step S905). If a bonus notification has been made, the process returns to step S901. Even when there is a big bonus or a regular bonus in step S904, the process directly returns to step S901.

  If the bonus notification is not performed in step S905, for example, a random number for notification / notice determination is extracted by the software random number function, and whether the value of this random number and the gaming state is RT is notified (ie, the RT is stored in the RAM 122) If the notification flag is set), or if it is informed that it is RT, the number of remaining RT games is 20 games or more depending on the gaming state saved in the RAM 122 in the previous game (that is, the gaming state in the current game). Depending on whether or not, a notice / notice determination lottery for determining whether to give a bonus notice or bonus notice is performed (step S906). However, when replay (or watermelon or bell) is won, it may be determined that the bonus notice is not performed.

  It is determined whether or not it has been decided in this notice / notice determination lottery to give a bonus notice or to give a bonus notice (step S907). If it is determined that neither bonus notification nor bonus notice is to be performed, the process returns to step S901. When it is decided to give a bonus notice or bonus notice, a bonus notice or bonus notice is given on the liquid crystal display 4 or the bonus notice unit 36 in the manner decided by the lottery (step S908).

  Next, it is determined whether the bonus notification or bonus notice is performed (step S909). If it is a bonus notification, a notification flag is set in the RAM 122 (step S910), and the process returns to step S901. If it is a bonus notice, a notice flag is set in the RAM 122 (step S911), and the process returns to step S901.

  If the received command type is the reel rotation command transmitted in step S404, first, the symbol display mode in the variable display device 2 stored in the RAM 122 based on the reel stop command received in the previous game is first displayed. The information shown is cleared (step S912). Further, the virtual reel is displayed on the liquid crystal display 4 to start the symbol variation display by the virtual reel (step S913). Then, the process returns to step S901.

  If the received command type is a reel stop command transmitted each time the rotation of the reels 3L, 3C, 3R is stopped in step S405, the command is derived to the reels 3L, 3C, 3R indicated by the reel stop command. Information indicating the displayed symbol is stored in a predetermined area of the RAM 122 (step S914). Furthermore, referring to the information indicating the setting status of the winning flag stored in the RAM 122 and the information indicating the stop status of the reels 3L, 3C, 3R, any one of the three is selected according to the stopped reels 3L, 3C, 3R. The virtual reel is stopped, and a symbol corresponding to the symbol derived to the variable display device 2 is derived to the virtual reel (step S915). Then, the process returns to step S901.

  If the received command type is the winning information command transmitted in step S715, it is determined whether or not a bonus notice is being performed on the liquid crystal display 4 depending on whether or not a notice flag is set in the RAM 122 ( Step S916). If a bonus advance notice has been performed, the bonus advance notice is terminated here, and the advance notice flag set in the RAM 122 is erased (step S917). Then, the process returns to step S901.

  If the bonus notice is not performed, it is determined whether or not the bonus notification is performed by the liquid crystal display 4 and / or the bonus notification unit 36 based on whether or not the notification flag is set in the RAM 122 (step S918). If the bonus notification is performed, it is determined whether or not the received winning information command indicates a winning of the regular bonus, the big bonus (1), or the big bonus (2) (step S919).

  If the winning of the regular bonus, the big bonus (1) or the big bonus (2) is indicated, the bonus notification is terminated here, and the notification flag set in the RAM 122 is erased (step S920). Then, the process returns to step S901. If no bonus notification has been made in step S918, or if no regular bonus, big bonus (1), or big bonus (2) has been won in step S919, the process directly returns to step S901. .

  If the received command type is the gaming state command transmitted in step S814, first, the gaming state indicated by the received gaming state command is stored in the RAM 122 (step S921). Next, it is determined whether or not the gaming state saved here (that is, the gaming state applied in the next game) indicates RT (step S922). If it indicates that it is RT, it is determined whether or not the fact that the gaming state is at RT is notified depending on whether or not the RT notification flag is set in the RAM 122 (step S923). If it is already informed that it is at RT, the process directly returns to step S901.

  If it is not notified that the gaming state is in RT, for example, a random number for RT notification lottery is extracted by a software random number function, and it is determined whether or not RT notification is performed according to the extracted RT notification lottery random value. RT notification lottery is performed (step S924). In this RT notification lottery, it is determined whether or not it is determined to perform RT notification (step S925). If it is not determined to perform the RT notification, the process directly returns to the process of step S901.

  When it is determined that the RT notification is to be performed, the fact that the gaming state is RT is displayed on the liquid crystal display 4 to notify the player. However, the information notified here cannot specify the number of remaining RT games. Further, any information output to the outside of the slot machine 1 does not make it possible to specify the number of remaining RT games. Also, an RT notification flag indicating that the gaming state is in RT is set in the RAM 122 (step S926). Then, the process returns to step S901.

  If it is determined in step S922 that the gaming state does not indicate RT, it is determined whether or not the fact that the gaming state is at RT is notified by whether or not the RT notification flag is set in the RAM 122. (Step S927). If there is no notification that there is at RT, the process returns to step S901. If it is notified that it is in RT, the notification that the gaming state being performed in the liquid crystal display 4 is in RT is terminated, and the RT notification flag set in the RAM 122 is deleted (step S928). Then, the process returns to step S901.

  If the received command type is another command, processing corresponding to the type of each command (the details are omitted because it is not related to the present invention) is executed (step S929). Thereafter, the process returns to step S901.

  As described above, in the slot machine 1 according to this embodiment, when the RT symbol is derived to the variable display device 2 in the normal gaming state, the gaming state is controlled to RT. The gaming state of RT continues for 100 games unless a regular bonus, a big bonus (1) or a big bonus (2) is won. Here, in each game in which the gaming state is controlled to RT, an RT notification lottery is performed on the condition that the gaming state is not yet notified to RT, and the gaming state is changed to RT by winning this. The player is informed that there is For this reason, even if the player misses the derivation of the RT symbol to the variable display device 2, the player can surely know that the RT is controlled by this notification, and the RT is continued. On the other hand, it is possible to give the player a sense of expectation and improve the interest of the game.

  On the other hand, if the player misses the derivation of the RT symbol to the variable display device 2, even if it is notified that the gaming state is in RT, this notification is not performed unless the RT notification lottery is won. The start time of RT cannot be specified. Further, the player is not notified of any information that can specify the number of remaining RT games other than the derivation of the RT symbol to the variable display device 2. For this reason, even if the liquid crystal display 4 informs that the gaming state is RT, the player cannot immediately predict the end of RT, and RT will continue regardless of the actual number of remaining RT games. On the other hand, it is possible to give the player a sense of expectation and improve the interest of the game.

  Further, the result of each game in the slot machine 1 is shown by the display mode derived to the variable display device 2 composed of the reels 3L, 3C, 3R, but corresponds to the display mode of the variable display device 2. The display mode is also indicated by a virtual reel displayed on the liquid crystal display 4. The liquid crystal display 4 is larger than the variable display device 2 and is close to the height of the player's line of sight, so that the liquid crystal display 4 can be easily viewed without displaying the variable display device 2 by displaying a virtual reel. become.

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

  By the way, in the slot machine 1 according to this embodiment, there is no missing role other than the regular bonus, the big bonus (1), the big bonus (2) and the watermelon, and the profit (five medals) is relatively low. Since the winning probability of watermelon is low, the game can be advanced with almost no intention except when a bonus notice or bonus notice is given. In addition, since the display mode corresponding to the display result of the variable display device 2 is derived from the virtual reel of the liquid crystal display 4, it is not necessary to see the variable display device 2 itself in many cases.

  Here, when the RT symbol that triggers the control of the gaming state to RT is derived to the variable display device 2, the display mode derived to the virtual reel of the liquid crystal display 4 is "other than watermelon-watermelon-watermelon". Yes, it is not a combination of symbols of the same type. In a general slot machine other than the slot machine 1 according to this embodiment, the winning display mode is often configured by a combination of symbols of the same type. Therefore, such a combination of symbols of different types is derived. Even so, it is possible to prevent the player from noticing the derivation of the RT symbol to the variable display device 2.

  In addition, the display mode of “other than watermelon-watermelon-watermelon” derived to the virtual reel when the RT symbol is derived to the variable display device 2 is a variable display device in which a completely losing display mode other than the RT symbol derivation is displayed. Also when derived to 2, it is derived to the virtual reel. In addition, the display mode of “other than watermelon-watermelon-watermelon” is often derived to the virtual reel when the complete loss is derived than when the RT symbol is derived in the variable display device 2. For this reason, even if the display mode of “other than watermelon-watermelon-watermelon” is derived on the virtual reel, it is possible to prevent the player from noticing the RT symbol to the variable display device 2.

  Furthermore, the RT symbol derived in the variable display device 2 is also composed of a combination of completely different types of symbols “white 7-bell-JAC”. Furthermore, since there are only 2/8 linear effective lines in the variable display device 2, considering only the linearly arranged symbols, there may be further different symbol combinations. In a general slot machine other than the slot machine 1 according to this embodiment, the winning display mode is often configured by a combination of symbols of the same type. Therefore, such a combination of symbols of different types is derived. Even so, it is possible to prevent the player from noticing the RT symbol on the variable display device 2.

  Thus, by making it difficult for the player to notice that the RT symbol has been derived to the variable display device 2, it is possible to make it difficult for the player to understand the start of the RT gaming state by deriving the RT symbol. By not knowing the start of RT, the player will not be able to predict the end of RT, so give the player a sense of expectation for RT continuation regardless of the actual number of RT remaining games , You can improve the fun of the game.

  In the slot machine 1 according to this embodiment, the regular bonus, the big bonus (1) or the big bonus (2) is won as an effect other than the display of the virtual reel and the notification that the gaming state is at RT. A bonus notice for notifying the fact that the player is present and a bonus notice for notifying that there is a possibility of winning the regular bonus, the big bonus (1) or the big bonus (2) are performed. By this bonus notification or bonus announcement, the player's expectation for winning the regular bonus, the big bonus (1) or the big bonus (2) can be increased, and the interest of the game can be improved.

  Here, the bonus notification and the bonus advance notice are performed at different ratios depending on whether or not it is notified that the gaming state is in RT and the difference in the number of remaining RT games. For this reason, even if it is not possible to predict the end of RT simply by notifying that the gaming state is in RT, the number of games remaining until the end of RT is predicted to some extent due to the difference in the frequency of bonus notification and bonus notice It will be possible. In this way, bonus announcements and bonus announcements give players not only information on whether they have won the regular bonus, big bonus (1) or big bonus (2), but also information on continuation / termination of RT. Therefore, the player's interest can be further attracted, and the interest of the game can be further improved.

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

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

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

  The rotation of the reels 3L, 3C, and 3R is stopped within the range of the maximum stop delay time of 190 milliseconds after the operation of the stop buttons 12L, 12C, and 12R is detected by the stop switches 42L, 42C, and 42R. Since 4 frames can be drawn during this period, the symbol to be stopped can be selected from the range of 5 frames. Since the active line is a combination of either the upper or lower stage, it is not missed when the small part of the bell is won. In particular, the bells in the regular bonus will be won with a very high probability of approximately 1 / 1.03, but this will not be missed, so the player will effectively hold on to the regular bonus. It becomes unnecessary, and it becomes possible to advance the game easily.

  As described above, the types of winning combinations that are subject to internal lottery for each gaming state are registered in the winning combination table by gaming state, but the number of judgment values that determine the winning probability of each combination is referred to from the determining table. Stored in the address. For the watermelons, bells and cherries defined as winning combinations in any game state in the role-specific table, the storage address of the determination value number is registered for each bet number, and the number of determination values according to the bet number (Although the same determination number is acquired as a result for watermelon and cherry).

  Here, the number of bets in the regular bonus is fixed at 1, but the number of bets in the gaming state other than the regular bonus is fixed at 3. Thereby, the internal lottery of watermelon, bell, and cherry can be performed with the winning probability according to the gaming state only by acquiring the number of determination values according to the number of bets. In addition, since it is not necessary to determine the gaming state when acquiring the determination value number, the processing steps in the internal lottery are simplified. Moreover, the betting number 1 corresponding to the regular bonus has a higher probability of winning the bell than when the betting number is 3, so that the player's expectation in the regular bonus is further increased and the interest of the game is improved. Can do.

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

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

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

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

  In addition, in the normal gaming state or RT, the number of determination values is registered for the regular bonus, the big bonus (1), the big bonus (2), and the cherry as a lottery target. Here, if none of the regular bonus winning flag, big bonus (1) winning flag, and big bonus (2) winning flag has been carried over from the previous game, depending on the value of the random number for internal lottery, Both the big bonus (1) or the big bonus (2) and the cherry are won.

  Here, even if the winning part of “cherry” is won based on the display result of the variable display device 2 based on the cherry winning flag set based on the winning of the cherry that is one of the lottery targets, the regular bonus is still maintained. There is a possibility that any of a winning flag, a big bonus (1) winning flag, and a big bonus (2) winning flag is set. Therefore, even when winning the “Cherry” small role, the player can expect the regular bonus, the big bonus (1), or the big bonus (2) to be won, improving the fun of the game. Can be made.

  The random number for internal lottery acquired by the random number acquisition process is not used as it is from the random number generation circuit 115 by the sampling circuit 116 but is used after being processed by software. The random number generation circuit 115 generates a random number by updating at a high speed with the frequency of the pulse signal of the pulse generation circuit 115a. However, in the random number for internal lottery processed by software, the periodicity of the update is increased by the processing. It will be lost.

  On the other hand, in the internal lottery, by sequentially adding the number of determination values corresponding to each combination to the value of the random number for internal lottery, the value of the random number for internal lottery winning each combination is It will harden. On the other hand, it is possible to prevent the player from aiming as much as possible by losing the periodicity of the random numbers for internal lottery by processing by software and varying the values.

  Moreover, the frequency of the pulse signal generated by the pulse generation circuit 115a to update the values of the counters 115b and 115c of the random number generation circuit 115 is higher than the frequency of the operation clock of the CPU 111, and is not an integral multiple. For this reason, the update of the random number generated by the random number generation circuit 115 becomes difficult to synchronize with the processing performed by the CPU 111. In addition, by increasing the frequency of the pulse signal of the pulse generation circuit 115a, the update speed of the random number generated by the random number generation circuit 115 can be made extremely fast.

  On the other hand, the processing of random numbers by software is performed by replacing the upper byte and lower byte of the random number extracted from the random number generation circuit 115 by the sampling circuit 116, masking the 15th and 7th bits, and then bit-shifting the upper byte. Good. Therefore, even for a relatively large random number of 16 bits (actually masked 14 bits), the load required for processing necessary to lose periodicity is not so large, and can be easily obtained. Can do. Since a large random number can be acquired in this way, the probability setting in the internal lottery can be finely performed.

  Further, in the slot machine 1 according to this embodiment, when an abnormality occurs in the data stored in the RAM 112, it is controlled to the RAM abnormality error state, the progress of the game is disabled, and the setting change mode is set. If the setting value is not newly selected and set based on the setting change operation, the state where the progress of the game is disabled is not released. That is, even if an abnormality occurs in the data stored in the RAM 112, the setting value selected and set based on the setting change operation (in general, the setting value) is not set automatically by the slot machine 1. Since the change operation is performed by an employee of the game shop, it is ensured that the game is played based on the setting value selected by the game shop), so that the game can be fair.

  In addition, when determining whether or not to win the winning combination in the internal lottery, the set value stored in the set value work 112-4 must be an appropriate value (a value in the range of 1 to 6). For example, instead of deciding whether or not to win based on a probability based on a default setting value (for example, setting 1), in this case as well, the game is controlled to a RAM abnormal error state and the progress of the game is disabled The state where the progress of the game is disabled is not canceled unless the setting change mode is entered and the setting value is newly selected and set based on the setting changing operation. In other words, even when it is not possible to properly determine whether or not to win the winning combination in the internal lottery, the game may be played based on the setting value selected and set based on the setting change operation. Since it is secured, the fairness of the game can be achieved.

  Further, the data stored in the RAM 112 is abnormal in most cases when the control cannot be continued due to a malfunction in the control such as a power failure or the control unit 110 running away. Since it is determined whether or not the data is normal only when the control unit 110 is activated after recovering from these states, the determination whether or not the data stored in the RAM 112 is normal is abnormal. Can only be done in situations where there is a high probability that That is, in a situation where there is a low possibility that an abnormality has occurred in the data stored in the RAM 112, it is not necessary to perform the determination, and the load on the control unit 110 can be reduced.

  In particular, in the power interruption interrupt process executed by the input of the voltage drop signal generated when the power is cut off, the RAM parity is calculated based on the data stored in the RAM 112 and stored in the parity storage area 112-7. At the next startup, the RAM parity obtained by the calculation is compared with the RAM parity stored in the parity storage area 112-7 to determine whether the data in the RAM 112 is normal. 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, when an abnormality occurs in the data of the RAM 112 and the progress of the game is disabled, a setting change mode in which a setting value changing operation that becomes a condition for releasing the disabled state of the game is enabled Along with the transition to (setting change process), the data stored in the RAM 112 is initialized. For this reason, the initialization of data associated with the occurrence of an abnormality in the data in the RAM 112 and the initialization of data associated with selection / setting of the set value can be performed at one time, so that useless processing can be omitted. .

  Further, when the control unit 110 is activated, it is determined whether or not the setting key switch 92 is ON before determining whether or not the data in the RAM 112 is normal. At that time, the setting key switch 92 is If it is determined that the data is in the ON state, the process proceeds to the setting change mode without determining whether the data in the RAM 112 is normal. In this way, a new set value is selected and set without determining whether or not the data in the RAM 112 is normal, so that useless processing can be omitted.

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

  In the above-described embodiment, in addition to the symbols being variably displayed by the reels 3L, 3C, and 3R of the variable display device 2, the effect symbols are displayed by the virtual reels displayed on the liquid crystal display 4 provided more easily than this. The present invention has been described by taking the slot machine 1 which displays the information in a variable manner as an example. However, as in the above embodiment, even if the RT symbol is composed of a combination of different types of symbols, or it is composed of a combination of the same type of symbols, it is not derived on a linear effective line. For example, a variable display device that is approximately the size of the liquid crystal display 4 may be provided at the position of the liquid crystal display 4. There is no need to display a virtual reel. Even in this case, the player can fully miss the derivation of the RT symbol to the variable display device, so that the effect of the present invention can be obtained.

  Further, the effect design is variably displayed by the virtual reel displayed on the liquid crystal display 4 that is easier to visually recognize than the variable display device 2, and the display derived to the virtual reel when the RT design is derived on the variable display device 2. If the mode is the same as the display mode that can be derived even when the display mode of losing is derived in the variable display device 2, the RT symbol derived to the variable display device 2 is a combination of the same type of symbols. And may be derived on a linear effective line. Even in this case, the player can fully miss the derivation of the RT symbol to the variable display device, so that the effect of the present invention can be obtained.

  In the above embodiment, the RT symbol is derived to the variable display device 2 by dropping the watermelon as a small role, and the gaming state is controlled to RT. In the derivation of the RT symbol, no value other than the gaming state being controlled by the RT is given to the player. On the other hand, it is good also as what derives | leads-out RT symbol irrespective of omission of another role. By deriving the RT symbol, not only the gaming state is controlled to RT, but other values (medal payout and re-game) may be given to the player. For example, two types of replay A (JAC-JAC-JAC) and Replay B (JAC-JAC-Bell) are prepared as replays in a normal gaming state (they are subject to lottery as separate roles in internal lottery). When winning a replay B, a replay flag may be set in the RAM 112 to automatically set the number of bets in the next game and to control the gaming state to RT.

  In the above embodiment, if it is not notified that the gaming state is RT, the bonus notification and bonus notice are performed at the same frequency regardless of whether the gaming state is normal or RT. It was. On the other hand, even if the fact that the gaming state is RT is not notified, the bonus notification or bonus notice may be performed at a different frequency between the normal gaming state and the RT state. This makes it possible to attract the player's interest in whether or not the gaming state is controlled by RT depending on the frequency of bonus notification or bonus notice, so that the interest of the game can be further improved. become.

  In the above embodiment, the winning of the regular bonus, the big bonus (1), or the big bonus (2) is notified by bonus notification or bonus notice. In the slot machine 1 of the above-described embodiment, for example, the bell as a small role wins without being missed if it is elected regardless of the operation procedure (especially the operation timing) of the stop buttons 12L, 12C, 12R. In the case of a small part that may be missed by operating the stop buttons 12L, 12C, and 12R, a small part notification that informs the player of information that can identify the procedure for winning the selected small part It is good also as what performs. This small role notification can also be made at a different rate depending on whether or not the fact that the gaming state is RT is notified and the number of remaining RT games.

  In the above embodiment, when the RT symbol is derived by dropping a watermelon in the normal gaming state, the gaming state is controlled to 100 games RT. However, the number of continuous games of RT is not limited to 100 games, and can be an arbitrary number of games. The RT game number may be determined based on the result of the RT game number determination lottery performed when the RT symbol is derived in the normal gaming state. In this case, even if the player knows the start of RT from the display result of the variable display device 2, it is possible to prevent the player from predicting the end of RT.

  In the above embodiment, the fact that the game state is controlled to RT is notified on the condition that the RT notification lottery performed in each game after the game state is controlled to RT is won. However, the trigger for notifying that the RT gaming state is controlled is not limited to the case where such a lottery is won. For example, a replay winning (winning) in a RT gaming state continues for a predetermined number of games. It may be triggered by the fact that a predetermined small role (for example, cherry) is won (winned) in the gaming state of RT.

  In the above embodiment, the fact that it is controlled to the RT gaming state has been notified by information displayed on the liquid crystal display 4, but other methods, for example, audio output from the speakers 7L and 7R You may alert | report by changing (BGM etc.) from a normal game state. Further, the bonus notification and the bonus advance notice are not limited to those performed on the liquid crystal display 4, and may be performed, for example, by lighting the reel lamp 3LP in a predetermined pattern.

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

  FIG. 19 is a diagram schematically showing a winning determination table applied in this modification. FIG. 20 is a flowchart showing in detail a lottery process applied in this modification. Other configurations and processes are the same as those of the slot machine 1 according to the above embodiment.

  As shown in FIG. 19, the winning determination table includes a small role winning determination table and a bonus winning determination table for each gaming state, which are stored in the ROM 113 in advance. Both the small role winning determination table and the bonus winning determination table are prepared according to the set values, and those corresponding to the set values are used in the lottery process, but the illustration is omitted here. is doing. Note that JACIN in the small role game is a special role, but there is no carryover of the winning flag unlike the regular bonus, regular bonus in big game (RT), big bonus (1) or big bonus (2). A range of determination values is registered in the determination table.

  Here, as shown in FIG. 19A, the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is carried over from the previous game in the normal gaming state or RT. If not, an internal lottery is performed using both the small role table (1) corresponding to the normal gaming state or RT and the bonus winning determination table. In FIG. 19A, the hatched range is a regular bonus, a big bonus (1) or a big bonus (2) and a cherry if the value of the random number for internal lottery is a value within this range. It is the range that will be won by overlapping.

  On the other hand, even in the normal game state or RT, when the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is carried over from the previous game, FIG. As shown in (b), the internal lottery is performed using only the small game table (1) corresponding to the normal gaming state or RT. When the game state is a small role game or a regular bonus (including the case where it is provided during a big bonus), the regular bonus, the big bonus (1) and the big bonus (2) are not drawn in the first place. 19 (c) and 19 (d), only the small role table (2) corresponding to the small role game or only the small role table (3) corresponding to the regular bonus is used, and an internal lottery is performed. Is done.

  In the lottery process shown in FIG. 20, the process of steps S1001 to 1003 and the point of shifting to the RAM abnormality error process when it is determined in step S1002 that the set value is not in the range of 1 to 6 are described above. This is the same as the lottery process (steps S501 to S503 in FIG. 14). Further, the processing of transmitting a winning status notification command after the setting status of the winning flag in the game is confirmed (step S1014) is the same as the processing of step S520 in FIG.

  After obtaining a random number for internal lottery in step S1003, a winning combination determination table used for internal lottery is prepared using the small game winning determination table prepared according to the current gaming state (normal and RT, or regular bonus) and the set value. It sets as a table (step S1004). Next, a determination value for winning each combination registered in the set small role winning determination table is sequentially compared with a random number value for internal lottery acquired in step S1003 (step S1005) and set. It is determined whether or not any combination registered in the small combination winning determination table has been won (step S1006). When any winning combination is won, the winning flag of the winning combination is set in the RAM 112 (step S1007), and the process proceeds to step S1008. If no winning combination is won, the process proceeds to step S1008.

  In step S1008, it is determined whether the current gaming state is a regular bonus or a big bonus (small role game) depending on whether the regular bonus flag or the big bonus flag is set in the RAM 112. If the current gaming state is a regular bonus or a big bonus, the process proceeds to step S1014.

  If the current gaming state is neither a regular bonus nor a big bonus, it is either a normal gaming state or an RT. In this case, the regular bonus winning flag, big bonus (1) winning flag or big bonus ( 2) It is determined whether or not the winning flag has already been set in the game before the previous time and has been carried over without winning (step S1009). If the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag has already been set, the process proceeds to step S1014.

  If none of the regular bonus winning flag, the big bonus (1) winning flag and the big bonus (2) winning flag is set, the bonus winning determination table corresponding to the set value is used as the winning determination table used for the internal lottery. Set (step S1010). Next, the winning value of each combination registered in the set bonus winning determination table is sequentially compared with the random value for internal lottery acquired in step S1003 (step S1011), and the set bonus is determined. It is determined whether or not any combination registered in the winning determination table is won (step S1012). If any winning combination is won, the winning flag of the winning combination is set in the RAM 112 (step S1013), and the process proceeds to step S1014. If no winning combination is won, the process proceeds to step S1014.

  In this way, a separate winning determination table is prepared for the special role and the non-special role, and the random value for internal lottery corresponds to the value that is won for the special role in the normal gaming state or RT and is not When the special role corresponds to the winning value, the special role and the non-special role are won simultaneously. In this case, even if the display result of the variable display device 2 is a prize for a small role or a replay based on a winning flag for a non-special role such as a small role or a replay, the special role is still won. there is a possibility. Thereby, a player's expectation with respect to the winning of the special role can be enhanced, and the interest of the game can be improved.

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

  In this modification, the random numbers for internal lottery used for the determination of winning of special roles and the random numbers for internal lottery used for determination of winning of non-special roles were the same, but different random numbers were used. Also good. In addition, regardless of whether the regular bonus winning flag, big bonus (1) winning flag, or big bonus (2) winning flag is carried over, in the normal gaming state or RT, a small bonus winning determination table and bonus are provided. A lottery is performed using both the winning determination tables, and the regular bonus when the regular bonus winning flag, big bonus (1) winning flag, or big bonus (2) winning flag is carried over from the previous game. When winning the big bonus (1) or the big bonus (2), the winning may be invalidated.

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

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

  In the above embodiment, when the watermelon is missed by the operation timing of the stop button 12L in a state where the watermelon winning flag is set, the RT symbol is always derived on the active line. This is because “blue 7” and “white 7” are always arranged at intervals of 7 frames or less for the left reel 3L. On the other hand, when a watermelon is missed in the state where the watermelon winning flag is set, the RT symbol may be missed depending on the operation timing of the stop button 12L. For example, if the watermelon symbol combination is “blue 7-bell-blue 7” and the RT symbol combination is “white 7-bell-white 7”, depending on the operation timing of the stop buttons 12L and 12R, “blue 7- “Bell-white 7” or “white 7-bell-blue 7” may be derived, and the RT symbol may be missed. One or more of the stop buttons 12L, 12C, and 12R can be arbitrarily selected as the stop button that causes the watermelon (and the RT symbol) to be dropped depending on the operation timing.

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

  FIG. 21 is an explanatory diagram of a first modification of the processing (steps S503 and S1003) until the CPU 111 processes the random numbers extracted from the random number generation circuit 115 into random numbers for internal lottery by software. Also in the first modification, the random number extracted from the random number generation circuit 115 is stored in the 16-bit general-purpose register 111GR included in the CPU 111.

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

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

  FIG. 22 is an explanatory diagram of a second modified example of processing (steps S503 and S1003) until the CPU 111 processes the random numbers extracted from the random number generation circuit 115 into random numbers for internal lottery by software. Also in this example, the random number extracted from the random number generation circuit 115 is stored in the 16-bit general-purpose register 111GR included in the CPU 111.

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

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

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

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

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

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

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

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

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

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

  In the above embodiment, the determination value number storage area uses a 2-byte area to store the determination value number in each case. However, in a general slot machine, the number of judgment values for a combination such as a regular bonus, a big bonus (1), or a big bonus (2) may be set to exceed 255 in any gaming situation. Absent. Thus, for those that do not need to set the number of determination values exceeding 255, the number of determination values may be stored using only a 1-byte area.

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

  In the above embodiment, in the small role game, the normal gaming state, or RT, the game can be started only by setting 3 as the number of bets. On the other hand, even in a small role game, a normal game state or RT, the game can be started by setting 1 as the bet number, and further, the game can be started by setting 2 as the bet number. You may be able to make it.

  When 1 or 2 is set as the number of bets in the small role game, normal gaming state, and RT, the winning probability of the small role in the internal lottery is lowered as compared with the case where 3 is set as the bet number. The number of medals to be paid out when winning a prize can be increased. Further, in a slot machine that can set any one, two, or three betting numbers in a small role game, a normal gaming state, and RT, the number of determination values is stored in common for all of the setting values 1 to 6. In addition to having a combination, it is also possible to have a combination stored in common for all bets 1 to 3. In this case, the storage area for the number of determination values can be reduced according to the number of bets, and the storage capacity can be further reduced.

  In the above embodiment, when the gaming state is the big bonus, if the regular bonus medium flag is not set in the RAM 112 when the start lever 11 is operated, this is set and controlled to the regular bonus. However, the condition for controlling the gaming state in the big bonus) to the regular bonus is not limited to this. For example, on the condition that a predetermined result (JACIN) is derived as the display result of the variable display device 2 in the big bonus. It is good also as what controls to a regular bonus. In this case, when the gaming state is controlled to the big bonus, JACIN is also selected as a lottery target in the internal lottery, and when JACIN is won, the JACIN winning flag may be set in the RAM 112. JACIN winning is subject to the setting of the JACIN winning flag.

  In the above embodiment, the symbol of the winning combination is determined based on the symbol position and the setting status of the winning flag for each reel 3L, 3C, 3R when the operation of the stop button 12L, 12C, 12R is detected. The slot machine that stops the rotation of the reels 3L, 3C, and 3R is described as an example in a control method in which the pull-in control is performed so that the symbols are not aligned or the removal control is performed so that the symbols of the winning combination are not aligned.

  On the other hand, a reel in which the stop position of the symbol is registered in advance according to the setting position of the symbol position and the winning flag for each reel 3L, 3C, 3R when the operation of the stop button 12L, 12C, 12R is detected. With reference to the control table (selected in advance according to the setting status of the winning flag and the game state), the reels 3L, 3C, 3R are stopped by a table system in which the reels are stopped at the symbol stop position registered in the reel control table. The present invention can also be applied to a slot machine that stops rotation (see, for example, Japanese Patent No. 2627604). Here, in the reel control table, the stop position of the symbol is determined in advance, but is determined within the range of the maximum stop delay time of 190 milliseconds. That is, the symbols that are stopped by operating the stop buttons 12L, 12C, and 12R are selected within the range of the maximum stop delay time.

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

  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 periphery, 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 a bet number or giving a valuable value associated with winning has been 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.
