Description

  The present invention relates to a slot machine, and more particularly, to an effect of informing the possibility of being allowed to derive a special display result.

  A slot machine generally includes a variable display device having a plurality of reels on which a plurality of types of symbols are drawn on the outer periphery, and each reel starts to rotate when a player operates a start lever. When the player operates a stop button provided corresponding to each reel, the rotation is stopped within 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 with payout of medals, replay roles that can start the next game without setting the number of bets, and bonuses that are advantageous to the player such as regular bonuses and big bonuses. There are roles. For any winning combination, in order for the winning to occur, the winning of the winning combination is won by winning an internal lottery that is performed before the display result is derived to the variable display device (usually when the start lever is operated). The flag must be set.

  In the relationship between the winning combination and the internal lottery determined in the conventional slot machine, there are those in which internal lottery is performed separately for a plurality of winning combinations (specific small roles 1 to 3) having the same value (for example, Patent Documents). 1). In addition, there are a plurality of types of bonuses with different values to be given, and internal lottery is performed for each type of bonus (see, for example, Patent Document 2). For a plurality of bonuses having the same value but different symbol combinations, there is one in which an internal lottery is performed for each symbol combination (see, for example, Patent Document 3).

  In addition, among the roles determined in the slot machine, the bonus role is beneficial to the player after the next game due to the transition of the game state, unlike the small role and replay role that the player can profit only for the game concerned. It is what brings. Therefore, with regard to the setting of the bonus winning flag, the player is more interested than the setting of the winning flags of other roles. Here, there is a slot machine that continuously gives a player a sense of expectation for setting a bonus winning flag over a plurality of games by a continuous effect continuously performed over a plurality of games (for example, patents). Reference 4).

JP 2001-334019 A (paragraph 0044, FIG. 5) Japanese Unexamined Patent Publication No. 2000-5381 (paragraphs 0032 to 0036, 0054 to 0057, FIGS. 5 and 9) Japanese Patent No. 3172464 (paragraph 0051, table 2) JP 2002-224282 A (paragraphs 0094 to 0105)

  For example, as shown in Patent Document 4, the bonus winning flag is carried over after the next game if no winning is made. Here, when the bonus winning flag is set, a continuous effect is performed with a relatively high probability, so that the player can be expected to win the bonus while the effect is continued over a plurality of games. .

  However, if the player's stop operation timing is appropriate when the bonus winning flag is set, it is always possible to win a bonus. If the player performs a stop operation, the player may know whether or not the bonus is won based on the display result derived here. In this case, there is a problem that the continuous production continued in the subsequent game becomes meaningless and the player is bothered by meaningless production.

  Even if an effect indicating the possibility of deriving the special display result is determined as a continuous effect that continues over a plurality of games, the present invention makes the continuous effect meaningless. An object of the present invention is to provide a slot machine that can be completed to the end.

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,
A fluctuation start control means (step S4) for starting the fluctuation display of the identification information in the variable display device when a predetermined fluctuation start condition (operation of the start lever 11) is established;
Stop operation means (stop buttons 12L, 12C, 12R) for instructing to stop the variation display of the identification information by the player's operation;
Stop operation detection means (stop switches 42L, 42C, 42R) for detecting the operation of the stop operation means;
Before the display result of the variable display device is derived, it is derived on the condition that the detection timing of the operation of the stop operation means is appropriate when it is determined to allow, and is different from the normal gaming state Prize display including multiple types (4 types) of special display results (Regular Bonus, Big Bonus (1), Big Bonus (2), Big Bonus (3)) accompanied by transition to a special gaming state where game value is given Predetermining means (FIG. 4 (a), step S3) for deciding whether to permit the derivation of the result by lottery,
When the stop operation detecting means detects an operation of the stop operation means, it is derived by stopping the change display of the identification information within a predetermined maximum delay time (190 milliseconds) from the detection of the operation. Fluctuation stop control means (steps S305, S309, S313) for deriving possible display results and displaying the display results according to the determination results of the prior determination means;
Special game state control means (steps S402, S404, S406, S408) for shifting the game state to the special game state when a special display result is derived by the variable stop control means;
When the pre-determining means determines that the derivation of any one of the plurality of types of special display results is permitted, if the special display result of the corresponding type is not derived based on the determination, the permission is determined. Special decision carry-over means (step S422 (deletes small role, replay, JACIN winning flag)) to carry over the decision after the next game until a special display result of the type being displayed is derived;
When it is determined that the derivation of any one of the plurality of types of special display results is permitted, the ratio is higher than when it is not determined that the derivation of any type of special display results is permitted. Continuous production means (steps S510, S511, S526, S530, S532, S534) for executing a continuous production showing the possibility that the derivation of the special display result is permitted;
When the execution of the continuous effect by the continuous effect means is finished (step S528 (YES) → step S529 (NO)), it is determined whether any one of the plural types of special display results is allowed to be derived. Special notification means (steps S532 and S534) for notifying information capable of specifying
The pre-determining means determines whether or not derivation is allowed exclusively for at least the plurality of types of special display results;
The operation timing of the stop operation means that can derive the display results of the variable display device within the range of the maximum delay time when it is determined that the derivation is allowed for the plurality of types of special display results. Is defined,
When it is determined that the derivation of any of the plurality of types of special display results is permitted, the variable stop control unit is configured to perform the stop operation unit according to the maximum delay time for each type of the special display results. The derivation is permitted on the condition that the stop operation means is operated at a special timing corresponding to the special display result of the type determined to permit the derivation among the special timings at which the operation timing is determined. To derive a special display result of the determined type of
The special timing for deriving at least one of the plurality of types of special display results is a timing that does not overlap with the special timing for deriving at least one other special display result. There are a plurality of non-overlapping timing numbers of the stop operation means corresponding to all of the plurality of types of special display results determined according to the special timing that is not performed (FIG. 2),
The continuous effect means continues the predetermined effect for a plurality of predetermined games (two games) equal to or less than the number of non-overlapping timings of the stop operation means corresponding to all of the plural types of special display results. It is characterized by being executed.

In the slot machine, whether to permit derivation is determined for each type of special display result. Each other and at least one special display result special timing is constant because of the special timing determined according to the operation timing of the stop operation means other in order to derive the determined special display result that allows the derivation There may be no overlap. As a result, the plurality of types of special displays that are determined according to special timing that does not overlap at least until it is determined whether or not the derivation of all types of special display results is permitted after the execution of the continuous performance is started. As many games as the number of non-overlapping timings of the stop operation means corresponding to all the results are required.

  For this reason, it is determined that the derivation of another type of special display result is permitted just because the special display result corresponding to the operation timing of the stop operation means is not derived when the continuous performance is performed. There is. Finally, when the execution of the continuous production is finished, that is, when there is a possibility that the derivation of the special display result may be permitted by the display result of the variable display device, a plurality of special types Information that can specify whether or not to permit derivation of any of the display results is determined is notified. Therefore, as long as the execution of the continuous effect is continued, the player can expect to derive any kind of special display result, and the continuous effect does not become meaningless.

  The special gaming state referred to here is a gaming state in which the payout rate determined by the number of valuable values paid out for the number of bets set by the player can be made higher than the normal gaming state. Thus, for example, one or more of a big bonus, a regular bonus, CT, AT, and RT can be included. In addition, as game characteristics, there may be a plurality of types of the same special gaming state, for example, there may be a plurality of types of big bonuses having different upper limits on the number of valuables paid out.

In the above slot machine,
The continuous production means performs the continuous production, and when a game in which a winning display result different from any kind of special display result is generated (step S529 (YES)), The number of games in which the continuous effects are continuously executed may be extended by a certain number (step S530, the effect state flag is not updated).

  In a game in which a winning display result that is different from any type of special display result is derived, the player knows from the result of the variable display device whether it is decided to allow the derivation of the special display result anyway. There is no end. Therefore, by extending the number of games for continuous production when such a game occurs, it is possible to give the player a sense of expectation over a longer period and improve the interest of the game. Here, if a winning display result different from any type of special display result is not derived when the continuous effect is being executed, the continuous effect ends with the predetermined plurality of games, and the continuous effect is executed. If a winning display result that is different from any type of special display result is derived at the same time, the continuous effect is obtained by adding a game in which a winning display result different from the special display result is added to the predetermined plurality of games. Will end with the number of games played.

In the above slot machine,
When the special display result is derived, the first special display result (big bonus (1) to (3)) that shifts to the first special gaming state (big bonus) and the second special gaming state (regular) 2nd special display result (regular bonus) transferred to (bonus). In this case,
The special notification means notifies the derivation at a predetermined rate (step S536) when notifying the information that can be specified that the derivation of any one of the plural types of special display results is permitted. By deriving a special display result that has been determined to be allowed, information that can specify whether the transition is made to the first special gaming state or the second special gaming state can be notified (step S515).

  Here, even if information capable of specifying that it is determined that the derivation of any one of a plurality of types of special display results is determined, the state is shifted to either the first or second special gaming state. There is a case where information capable of specifying is notified and a case where information is not notified. In the former, it is easy for the player to proceed with the game, and in the latter, the type of special display result determined to allow derivation is still unknown, so that the expectation can be further continued. Further, by enriching the notification mode in this way, the interest of the game can be improved.

The first special display result may include a plurality of types of special display results (big bonuses (1) to (3)) other than the second special display result. In this case,
The special notification means specifies which of the plurality of types of special display results included in the first special display result is determined to be permitted when notifying information capable of specifying the information. Possible information can be notified (step S515, notification to big bonuses (1) to (3)).

  Here, when there are a plurality of types of special display results to be shifted to the first special gaming state, not only the transition to the first special gaming state but also the types of special display results are notified, It is easy for the player to proceed with the game, and it is possible to eliminate the waste of operating the stop operation means aiming at the derivation of the special display result that is not actually allowed to be derived. It is possible to prevent a large loss from occurring.

  Note that the first special game state and the second special game state can be classified by, for example, a difference in the end condition (for example, the number of game values paid out) of the special game state. Further, classification can be made according to whether or not the game state is shifted to a predetermined game state (so-called AT, RT, etc.) that is different from the normal game state and the special game state after the special game state ends. Moreover, it can also classify | categorize by the difference in the game playability of the said special game state (JAC game only, small role game + JAC game, CT, etc.). In addition, it is possible to classify according to the difference in the probability of allowing the derivation of the small role display result in each game in the special gaming state or the difference in the number of valuable values given when the small role display result is derived. Furthermore, it can classify | categorize also by these combination.

The slot machine is
Numerical data input means for inputting numerical data updated within a predetermined range to a predetermined determination area (general-purpose register 111GR) as determination numerical data (internal lottery random number) at a predetermined timing for each game (step S101)
The pre-determining unit can determine whether or not to allow the plurality of types of winning display results to be derived according to the value of the numerical data for determination input in the determination area.
In this case, the slot machine is
One of the allowable stages (setting values 1 to 6) having different probabilities of determining that the pre-determining means allows the winning display result to be derived is selected and set. An allowable stage setting means (setting switch 91);
With respect to any one or more types of winning display results (JACIN, JAC, watermelon, cherry, replay), it is determined that the predetermination means permits derivation with respect to the determination numerical data input to the determination area. The judgment value data (number of judgment values) indicating the number of judgment values to be different is stored in common for the plurality of types of permissible stages, and the judgment value data is not stored in common for the permissible stages. For the winning display result (regular bonus, big bonus (1) to (3), bell), determining that the predetermination means permits the derivation for the determination numerical data input to the determination area It is further provided with determination value data storage means (FIG. 4B, FIG. 5) that individually stores determination value data indicating the number of determination values to be determined according to the type of the allowable stage. Door can be. here,
The pre-determining means is the determination numerical data input to the determination area in accordance with the determination value data stored in the determination value data storage means corresponding to the allowable stage set by the allowable stage setting means. Includes determination means (step S110 (determined to indicate that it is permitted by overflow)) that determines whether or not derivation is permitted for each type of winning display result, and derivation is permitted by the determination means. A decision is made to allow the derivation of the winning display result of the type determined to indicate that it is to be performed (step S111),
The determination value data storage means includes different number determination value data (FIG. 4B, FIG. 5: regular bonus) indicating the number of different determination values as determination value data to be stored individually according to the type of the permissible stage. The same number determination value data (FIG. 4B, FIG. 5: Big bonus (1) to (3), bell) indicating the number of the same determination values as the determination value data stored separately according to the type of the permissible stage. ) May be stored according to the type of the winning display result.

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

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

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

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

In this case,
The predetermination means sequentially inputs the judgment value data stored in the judgment value data storage means corresponding to the allowable stage set by the allowable stage setting means to the determination area for each type of winning display result. An addition means (step S109) for adding to the determined numerical data for determination may be further provided. here,
The determination means determines whether or not the addition result of the addition means exceeds the predetermined range (step S110), and performs addition when it is determined that the predetermined range is exceeded by the determination result. It can be determined that it indicates that the derivation of the winning display result of the type corresponding to the determination value data is permitted (step S111).

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

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

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 S202) for inputting into the area (general-purpose register 111GR) can be further provided.
The prior determination means may determine whether or not to allow the plurality of types of winning display results to be derived in accordance with the value of the determination numerical data input to the determination area. (Steps S109 and S110). 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 S202) for inputting an n-bit array data signal output from the latch circuit as n-bit numeric data without changing the bit array order into a predetermined specific area (general-purpose register 111GR). Can be provided,
The numerical data input means replaces the specific bit data of the n-bit numerical data input to the specific area with the other bits of the numerical data, and performs the replacement n Bit replacement numerical data can be input to the determination area as the determination numerical data (steps S203 to S205).

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

The slot machine 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 S202) for inputting into the area (general-purpose register 111GR) can be further provided.
The prior determination means may determine whether or not to allow the plurality of types of winning display results to be derived in accordance with the value of the determination numerical data input to the determination area. (Steps S109 and S110). 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,
Input means for inputting the n-bit array data signal output from the latch circuit into the predetermined specific area (general-purpose register 111GR) as n-bit first numerical data without changing the bit array order (FIG. 16) When,
Numerical value updating means (refresh register 111R) for updating the second numerical data at a predetermined timing;
Numerical value extraction means (FIG. 16) for extracting second numerical data updated by the numerical value update means when the predetermined extraction condition is satisfied;
The second numerical data extracted by the numerical value extraction means for the upper k bits in the first numerical data of the upper k bits (k is a natural number: k <n) and the lower j bits (j = n−k) is used. And a calculation means (FIG. 16) for performing a predetermined calculation.
The numerical data input means may input operation result numerical data consisting of upper k bits and lower j bits after the operation by the operation means to the determination area as the determination numerical data (see FIG. 16).

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

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

The slot machine 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 S202) for inputting into the area (general-purpose register 111GR) can be further provided.
The prior determination means may determine whether or not to allow the plurality of types of winning display results to be derived in accordance with the value of the determination numerical data input to the determination area. (Steps S109 and S110). 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,
Input means for inputting the n-bit array data signal output from the latch circuit into the predetermined specific area (general-purpose register 111GR) as n-bit first numerical data without changing the bit array order (FIG. 17) When,
First numerical value updating means (refresh register 111R) for updating the second numerical data at a predetermined timing;
Second numerical value updating means (refresh register 111R) for updating third numerical data different from the second numerical data at a predetermined timing;
First numerical value extracting means (FIG. 17) for extracting second numerical data from the first numerical value updating means when a predetermined extraction condition is satisfied;
Second numerical value extracting means (FIG. 17) for extracting third numerical data from the second numerical value updating means when a predetermined extraction condition is satisfied;
The second numerical value extracted by the first numerical value extraction means for the upper k bits in the first numerical data of the upper k bits (k is a natural number: k <n) and the lower j bits (j = n−k). Computation means (FIG. 17) for performing a predetermined operation using data and performing a predetermined operation using the third numerical data extracted by the second numerical value extraction means for the lower j bits And can
The numerical data input means inputs arithmetic result numerical data consisting of upper k bits after the operation by the arithmetic means and lower j bits after the operation as the determination numerical data to the determination area. Yes (FIG. 17).

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

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

  The 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.

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

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

The slot machine is

Can do. In this case,
The pre-determining means includes
A re-game display result (replay) accompanied by a re-game that can be played without using a valuable value that can be used for setting at least the bet amount when being controlled in the normal gaming state, and the It is determined whether or not the derivation of a plurality of types of special display results is allowed, and a small role display result (watermelon, bell, cherry) accompanied by a valuable value that can be used for setting the number of bets with a predetermined probability. Deciding to allow derivation (FIG. 4 (a), FIG. 6 (a)),
Decide whether to allow at least derivation of the small role display result and the special special display result when the special game state corresponding to the specific type of special display result is not controlled to the special special game state (Fig. 4 (a), Fig. 6 (b)),
When the special game state corresponding to the specific type of special display result is controlled to the special special game state, it is determined that the derivation of the small role display result is allowed with a probability equal to or higher than the predetermined probability. (FIG. 4 (a), FIG. 6 (c)).

  Here, when the game is controlled in the normal game state, the special game state corresponding to a specific type of special display result is not controlled in the special special game state, and when the game is controlled in the special special game state. In this case, the prior determination means determines whether or not to allow the derivation of the small combination display result. The small combination display result is accompanied by the addition of a valuable value due to the occurrence of a prize, and is a basic prize display result in a game of a slot machine. Thus, by determining the small combination display result, which is the basic winning display result, as the type of winning in any gaming state, the game becomes easy for the player to understand. In addition, the probability that it is decided to allow the derivation of the small role display result is more than that when it is controlled to the normal gaming state when it is controlled to the special special gaming state. By being controlled, the player's expectation for derivation of the small role display result is not reduced.

  In this case, the pre-determining means is configured so that the special special display result and the small role display result when the special game state corresponding to the specific type of special display result is not controlled to the special special game state. It is also possible to determine whether or not to permit the derivation of only (FIG. 4 (a), FIG. 6 (b)).

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

  The special special display result is preferably composed of a combination of identification information (watermelon-JAC-JAC) different from the combination of identification information constituting the winning display result in the normal gaming state (see FIG. 4 (a)).

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

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

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

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

  The random number generation circuit 115 is configured by a counter that counts up and updates the value every time a predetermined number of pulses are generated, as will be described later, and the sampling circuit 116 acquires the numerical value counted by the random number generation circuit 115. . The random number generation circuit 115 is provided for each type of random number used for the progress of the game, and a range of numerical values to be counted for each type of random number is determined. The CPU 111 sends an instruction to the sampling circuit 116 according to the processing to acquire the numerical value indicated by the random number generation circuit 115 as a random number (hereinafter, this function is referred to as a hardware random number function). A random number extracted by the hardware random number function is used as a random number for internal lottery described later.

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

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

These operations are controlled.

  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 reel control table corresponding to the gaming state in the ROM 113, controls the reel motors 3ML, 3MC, and 3ML via the reel relay board 103, and stops the reels 3L, 3C, and 3R. An effect control board 102 is further connected to the game control board 101 via an effect relay board 106.

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

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

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

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

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

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

  In the slot machine 1, the medal payout rate changes according to the set value, and the winning probability of the internal lottery described later is determined according to the set value. Hereinafter, a setting value changing operation using the setting switch 91 will be described.

  In order to change the setting value, it is necessary to turn on the power of the slot machine 1 by the main switch 94 after the setting key switch 92 is turned on. When the setting key switch 92 is turned on and the power is turned on, the setting value can be changed. When the setting switch 91 is operated during a period during which the setting value can be changed, the setting value is updated by 1 (when the operation is further performed from the setting 6, the setting is returned to the setting 1). Then, when the setting key switch 92 is turned off after the start lever 11 is operated, the determined setting value after the change is stored in the setting value storage area provided in the RAM 112.

  In the slot machine 1, a winning is awarded when the symbols are arranged on the active line set according to the betting number of the variable display device 2. The types of winning combinations are determined according to the gaming status, but can be broadly divided into special roles that involve the transition of gaming status, small roles that involve the payout of medals, and no need to set the number of bets. There is a re-player who can start the next game. In order for each winning combination determined according to the gaming state to occur, it is necessary to win an internal lottery to be described later and set a winning flag for the winning combination.

  FIG. 4A is a diagram showing a winning combination table by gaming state. The winning combination table according to gaming state is stored in advance in the ROM 113 and is used to determine the winning combination determined in the internal lottery. The registered content of the winning combination table according to gaming state depends on the gaming state. It shows the role that has been determined. As for the role in this slot machine 1, regular bonus as special role, big bonus (1), big bonus (2), big bonus (3), JACIN, JAC, watermelon, bell, cherry as small role, replay Replay is defined as a role.

  In the regular bonus game state, JAC, watermelon, bell, and cherry, which are small roles, are determined as winning roles, and are subject to lottery by internal lottery in the regular bonus. In the big bonus game state, JACIN, which is a special combination, and watermelon, bell, and cherry, which are small combinations, are determined as winning combinations, and are selected for lottery in an internal lottery in the big bonus. Under normal gaming conditions, regular bonuses and bonuses that are special roles, watermelons and bells and cherries that are small roles, and replays that are replaying roles are defined as winning roles. It becomes the object of lottery.

  The regular bonus is awarded when a combination of “BAR-BAR-BAR” is aligned on any of the active lines (five) in the normal gaming state. 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 is a combination of “red 7-red 7-red 7”, “white 7-white 7-white 7”, or “blue 7-” on any of the active lines (5) in the normal gaming state. When the combination of “Blue 7-Blue 7” is complete, a prize is awarded. When the big bonus 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 reaches 480.

  In addition, it is necessary to distinguish the big bonus by "Red 7-Red 7-Red 7", the big bonus by "White 7-White 7-White 7", and the big bonus by "Blue 7-Blue 7-Blue 7". In this case, they are referred to as big bonus (1), big bonus (2), and big bonus (3), respectively. Further, the regular bonus, the big bonus (1), the big bonus (2), and the big bonus (3) may be collectively referred to simply as “bonus”.

  JACIN is awarded when a combination of “watermelon-JAC-JAC” is placed on any of the active lines (5) 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. When the regular bonus in the big bonus reaches the aforementioned 480, the regular bonus is terminated together with the big bonus.

  JAC is awarded when the combination of “Bell-JAC-JAC” is aligned on the active line (1 line) in the regular bonus, but in a gaming state other than the regular bonus, even if this combination is aligned, Don't be. A watermelon is awarded when the combination of “watermelon-watermelon-watermelon” is aligned on any of the active lines (one or five) in any gaming state. A bell is awarded when the combination of “bell-bell-bell” is aligned on any of the active lines (one or five) in any gaming state. Cherry is awarded when the symbol “cherry” is derived on one of the active lines (one or five) for the left reel 3L in any gaming state. The payout of medals when these small roles are won will be described later.

  Replays are awarded when a combination of “JAC-JAC-JAC” is aligned on any of the active lines (5) in the normal gaming state, but regular bonus and big bonus (small role game and regular bonus) Then, even if this combination is complete, it will not be a replay prize. 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.

  The reference of the combination according to the gaming state is performed according to the winning combination table by gaming state shown in FIG. That is, when the gaming state is a regular bonus (including the case where the bonus is provided during the big bonus), JAC, watermelon, bell, and cherry are sequentially read out as the subject of the internal lottery, and the gaming state is small in the big bonus. When in a combination game, JACIN, watermelon, bell, and cherry are sequentially read out as target combinations for internal lottery.

  When in the normal gaming state, the regular bonus, big bonus (1), big bonus (2), big bonus (3), watermelon, bell, cherry, and replay are sequentially read out as the internal lottery target roles. However, the regular bonus winning flag, big bonus (1) winning flag, big bonus (2) winning flag, or big bonus (3) winning flag is set in the game before the previous game, and carry over without winning based on the flag. The regular bonus and the big bonuses (1) to (3) are not eligible for internal lottery.

  In the internal lottery, the number of determination values determined for the internal lottery target combination is sequentially added to the internal lottery random number, and when the addition result overflows, it is determined that the winning combination is won. If the winning combination is determined, the winning flag of the combination is set in the RAM 112. The number of determination values is read in accordance with the storage address of the number of determination values registered in the role table stored in advance in the ROM 113. FIG. 4B 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, Big Bonus (1), Big Bonus (2), and Big Bonus (3) are only eligible for internal lottery only in the normal gaming state and correspond to 3 bets in the normal gaming state. The storage address of the number of judgment values to be registered is registered. For these combinations, the value of the common flag is 0, and the storage address for the number of determination values is individually registered according to the set value. JACIN is an internal lottery target only in the small bonus game in the big bonus, and the storage address of the number of determination values corresponding to the number of bets in the small bonus game is registered. The value of the common flag for this role is 1, and a storage address for a common number of determination values is registered regardless of the set value.

  JAC is a role that is subject to internal lottery only with the regular bonus, and the storage address of the number of determination values corresponding to the bet number 1 with the regular bonus 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. Replay is a role that is subject to internal lottery only in a normal gaming state, and a storage address of a judgment value number 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.

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

  In the role-specific table, the number of medals to be paid out when winning each role is also registered. However, only the watermelons, bells, cherries, and JACs, which are small roles, are the targets for paying out medals when winning a prize. Watermelons, bells, and cherries can be awarded when the bet number is 1 (regular bonus) or 3 (game state other than the regular bonus), but for the bell, when the bet number is 1, That is, when the gaming state is a regular bonus, 15 medals that are more than the other 8 are paid out.

  The regular bonus, the big bonus (1), the big bonus (2), the big bonus (3), and the winning of JACIN are accompanied by a transition of the gaming state and are not eligible for paying out medals. Replay does not involve the payout of medals, but the medals used for setting the number of bets in the next game are no longer necessary, so that it is substantially the same as the payout of 3 medals.

  FIG. 5 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 is an address that is referred to when the target character of the internal lottery is a regular bonus and the set value is 1, and at this time, 31 that is a value stored here is acquired as the number of determination values. . Addresses ADD + 2, ADD + 4, ADD + 6, ADD + 8, and ADD + 10 are addresses that are referred to when the target character of the internal lottery is a regular bonus and the set value is 2 to 6, respectively. Regarding the regular bonus, the number of judgment values is individually stored according to the set value, but since the same number of judgment values is stored, the winning probability of the regular bonus is the same at any set value. Yes.

  The addresses ADD + 12, ADD + 14, ADD + 16, ADD + 18, ADD + 20, and ADD + 22 are addresses that are referred to when the internal lottery target is the big bonus (1) and the set value is 1-6. The addresses ADD + 24, ADD + 26, ADD + 28, ADD + 30, ADD + 32, and ADD + 34 are addresses that are referred to when the internal lottery target role is the big bonus (2) and the set value is 1 to 6, respectively. Addresses ADD + 36, ADD + 38, ADD + 40, ADD + 42, ADD + 44, and ADD + 46 are addresses that are referenced when the internal lottery target is the big bonus (3) and the set value is 1-6. For big bonuses (1), (2), and (3), the number of determination values is individually stored according to the set value, and a different number of determination values is stored. The winning probabilities of 1), (2), and (3) will be different.

  Addresses ADD + 48, ADD + 50, and ADD + 84 are addresses that are referred to regardless of the set value when the target role of the internal lottery is JACIN, JAC, or replay, respectively, and 4311, 27, respectively, regardless of the set value. , 2245 is acquired as the number of determination values.

  The address ADD + 52 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 combination of the internal lottery is a watermelon. The address ADD + 54 is an address that is referred to regardless of the set value when the number of bets is three, that is, in the normal gaming state or in the small role game, when the subject combination of the internal lottery is a watermelon. The number of determination values for watermelon is registered according to the number of bets, but since the same value is registered, the winning probability of watermelon is the same in any gaming state. As for cherry, the number of determination values is registered in the same manner at addresses ADD + 80 and ADD + 82.

  The addresses ADD + 56, ADD + 58, ADD + 60, ADD + 62, ADD + 64, and ADD + 66 are addresses that are referred to when the bet number is 1, that is, when the target character of the internal lottery is the bell and the set value is 1 to 6 in the regular bonus. is there. Since the same value is registered in each of the addresses ADD + 56 and ADD + 58, ADD + 60 and ADD + 62, and ADD + 64 and ADD + 66, the set value 1 and the set value 2, the set value 3 and the set value 4, and the set value are set. With 5 and the set value 6, the winning probability of the bell is the same.

  Addresses ADD + 68, ADD + 70, ADD + 72, ADD + 74, ADD + 76, and ADD + 78 are each when the bet number is 3, that is, when the target lot of the internal lottery is a bell and the set value is 1 to 6 in the normal gaming state or small role game This address is referred to by Since different values are registered in the addresses ADD + 68, ADD + 70, ADD + 72, ADD + 74, ADD + 76, and ADD + 78, in a normal gaming state or a small role game, the winning probability of the bell differs depending on the set value. .

  FIGS. 6A to 6C are diagrams illustrating examples of the relationship between the value of the random number for internal lottery and the number of determination values of each combination and the winning combination. FIG. 6A shows an example in a normal gaming state, FIG. 6B shows an example in a small role game, and FIG. 6C shows an example in a regular bonus. 6A to 6C show examples in which the set value is 6, and in FIG. 6A, both the regular bonus winning flag and the big bonus winning flag are set. An example is shown when there is not.

  For example, as shown in FIG. 6 (a), in the normal gaming state, the roles that are subject to the internal lottery are regular bonus, big bonus (1), big bonus (2), big bonus (3), watermelon , Bell, cherry, and replay. With the setting value 6, the number of determination values is 31, 20, 20, 20, 68, 3562, 269, and 2245, respectively. First, the regular bonus that is the target of the internal lottery is won when 16353 to 16383, in which the addition result overflows by adding 31 judgment values, is acquired as a random number for internal lottery.

  Next, for the big bonus (1) that is the subject of the internal lottery, the addition result overflows by adding 51 which is the sum of the regular bonus judgment value number 31 and the big bonus judgment value number 20. A win is made when ˜16352 is acquired as a random number for internal lottery. Similarly, big bonus (2) is obtained when 16313-16332 is obtained as a random number for internal lottery, and big bonus (3) is obtained when 16293-16312 is obtained as a random number for internal lottery. Is obtained when 16225-16292 is acquired as a random number for internal lottery, bell is acquired as random number for internal lottery when 12663-16224 is acquired as a random number for internal lottery, 12394-12626 is used as a random number for internal lottery When acquired, the replay is determined to be winning when 10149 to 12393 are acquired as random numbers for internal lottery.

  The approximate winning probabilities calculated for these combinations based on the number of judgment values are regular bonus, big bonus (1), big bonus (2), big bonus (3), watermelon, bell, cherry, and replay. 1 / 528.5, 1 / 819.2, 1 / 819.2, 1 / 819.2.1, 1 / 240.9, 1 / 4.6, 1 / 60.9, 1/7. 3 When 0 to 10148 is acquired as a random number for internal lottery, all combinations are lost.

  Further, as shown in FIG. 6B, in the small role game, JACIN, watermelon, bell, and cherry are subject to internal lottery, and the number of determination values is 4311, 68, 3562, and 269. -16383, 12005 to 12072, 8443 to 12004, and 8174 to 8442 are acquired as random numbers for internal lottery, and are determined to be winning. In addition, the approximate winning probabilities for each combination are 1 / 3.8, 1 / 240.9, 1 / 4.6, and 1 / 60.9. When 0 to 8173 is acquired as a random number for internal lottery, all the combinations are lost.

  In addition, as shown in FIG. 6C, in the regular bonus, JAC, watermelon, bell, and cherry are subject to internal lottery, and the number of determination values is 27, 68, 15919, and 269. When 16383, 16289 to 16356, 350 to 16288, and 101 to 369 are acquired as random numbers for internal lottery, it is determined that the winner is won. In addition, the approximate winning probabilities of each combination are 1 / 606.8, 1 / 240.9, 1 / 1.03, and 1 / 60.9. When 0 to 100 are acquired as random numbers for internal lottery, all combinations are lost.

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

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

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

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

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

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

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

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

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

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

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

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

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

  Next, 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. In other words, 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. A regular bonus winning flag, big bonus (1) winning flag, big bonus (2) winning flag, or big bonus (3) winning flag, watermelon winning flag, bell winning flag, cherry winning flag, or replay winning flag When set, derivation of the former takes precedence over the latter.

  As shown in FIG. 2, in any of the reels 3L, 3C, and 3R, “red 7”, “white 7”, and “blue 7” are arranged at intervals of 6 frames or more. For this reason, if the stop buttons 12L, 12C, and 12R are operated at the timing at which the big bonus (1) can be won (that is, the timing at which 5 frames before “Red 7” are displayed on the active line), Even if the bonus (2) winning flag and the big bonus (3) winning are set, the big bonus (2) and the big bonus (3) are not won.

  Similarly, when the stop buttons 12L, 12C, and 12R are operated at a timing when the big bonus (2) can be won, the big bonus (1) and the big bonus (3) are not won. When the stop buttons 12L, 12C, and 12R are operated at a timing at which the big bonus (3) can be won, the big bonus (1) and the big bonus (2) are not won.

  In the left reel 3L, “white 7” and “blue 7” are arranged in the four frames before and after “BAR”, but “red 7” is not arranged. On the four reels before and after “BAR” on the inner reel 3C, “red 7” and “blue 7” are arranged, but “white 7” is not arranged. “Red 7” and “White 7” are arranged in the four frames before and after “BAR” in the right reel 3R, but “Blue 7” is not arranged.

  Therefore, when the stop buttons 12L, 12C, and 12R are operated at a timing at which the regular bonus can be won (that is, when 5 frames before “BAR” are displayed on the active line), the big bonus (1), Neither the bonus (2) nor the big bonus (3) is won. On the other hand, in any case where the stop buttons 12L, 12C, and 12R are operated at the timing when the big bonus (1), the big bonus (2), and the big bonus (3) can be won, the regular bonus is won. There is no.

  In addition, when the bonus winning flag is set, even if it is a display result of losing from the viewpoint of winning a prize, a display result of reach eyes definitely indicating that the bonus winning flag is set is displayed on the variable display device 2. May be derived. There are common reach points for the regular bonus, the big bonus (1), the big bonus (2), and the big bonus (3), but the regular bonus, the big bonus (1), and the big bonus (2) There is also an individual reach for each of the big bonuses (3). There is also a common reach common only to the big bonus (1), the big bonus (2), and the big bonus (3).

  For example, when the big bonus (1) winning flag is set, the common reach and the individual reach corresponding to the big bonus (1) may be derived as the display result of the variable display device 2, but the regular bonus may be derived. No individual reach corresponding to each of the big bonus (2) and the big bonus (3) is derived. Similarly, when other types of bonus winning flags are set, only the common reach or individual reach corresponding to each is derived. If the bonus winning flag is not set, neither common reach nor individual reach is derived.

  In addition to the reach, the display result is derived when the bonus winning flag is not set and when it is set, but when the bonus winning flag is set, it is derived with a higher probability. There is a chance result (losing from the viewpoint of winning) that is the display result. As with the reach eyes, there are also common chance eyes and individual chance eyes. Among the above-mentioned common reach items, there are items that are individual chances regarding the regular bonus, the big bonus (1), the big bonus (2), and the big bonus (3).

  For example, as an individual chance, it is derived when any type of bonus winning flag is not set, and is derived with a higher probability when the regular bonus winning flag is set, but other types of bonus winning flags Some are not derived when the flag is set. It is derived as a common reach as an individual chance when any kind of bonus winning flag is set, but when a regular bonus winning flag is set, other types of bonus winning flags are set Some are derived with a higher probability than they are. It is derived when the bonus winning flag is not set or when it is set, but when the regular bonus winning flag is set, when other types of bonus winning flags are set, Some are derived with a higher probability than when the winning flag is not set.

  Derivation of common reach and common chance and individual reach and individual chance corresponding to regular bonus, big bonus (1), big bonus (2), big bonus (2) and big bonus (3) respectively The RAM 112 is controlled depending on whether a regular bonus winning flag, a big bonus (1) winning flag, a big bonus (2) winning flag, or a big bonus (3) winning flag is set.

  Next, commands that the CPU 111 of the game control board 101 transmits to the effect control board 102 will be described. The CPU 111 sends various commands according to the progress of each game, but as a basic command, the winning status notification command sent after the internal lottery is performed, the rotation of the reels 3L, 3C, 3R. There are a reel stop command that is sent when the player stops, and a winning information command that is sent after the display result is derived to the variable display device 2.

  The winning status notification command indicates the setting status of the winning flag in the RAM 112, and the gaming status applied in the next game based on the setting status of the big bonus medium flag and the regular bonus medium flag in the RAM 112. The reel stop command indicates the type of reel that has been stopped and the derived symbol. The winning information command indicates the presence / absence of a winning and the type of winning.

  The CPU 121 of the effect control board 102 performs an effect according to various commands sent from the CPU 111 of the game control board 101. As the effect, there is an effect of notifying that a bonus is won. The bonus winning notification is a concept including a notice that the player is surely won and that the player is notified that the bonus has been won.

  As an effect of informing the bonus winning, there is a continuous effect that is continuously performed over a plurality of games. The continuous effect is an effect for notifying the bonus winning, and is performed with a relatively high probability (for example, 30%) when the bonus winning flag is actually set, and when the bonus winning flag is not actually set. However, it may be performed with a low probability (for example, 1%). The final result of the continuous performance is a definitive indication of whether the bonus has been won or the bonus has been lost, but when the bonus win is announced, the next game or 5 bonus games will be announced. Will be.

  In order to notify the continuous effect and the type of bonus that has been won, the RAM 122 of the effect control board 102 is provided with an area for storing a win status notification command, and an effect state flag indicating the execution state of the continuous effect, And a fixed notification counter. The effect state flag is a flag indicating three states. When the state is 0, a continuous effect is not executed. When the state is 2, a game where a continuous effect is started is 1. This indicates that the game is a game in which continuous production has already started in the previous game.

  The final notification counter is a counter that indicates whether the winning bonus type has already been notified and the number of remaining games until the winning bonus type is notified. When the value is 0, It shows that the bonus election has not been announced yet. A value of 1 indicates that the type of bonus that has been won has already been announced. When the value is 2 to 6, it indicates the number of remaining games until the type of bonus that has been won is announced by a value obtained by subtracting 1 from the value.

  More specifically, when the continuous production is not performed, the winning status notification command transmitted when the start lever 11 is operated (that is, at the start of one game) is continuously performed with a probability corresponding to the presence / absence of bonus winning. When the effect lottery is performed and the winning effect is won, the start effect in the continuous effect is performed on the liquid crystal display 4 and the state of the effect state flag is set to 2. If a bonus result is not received by a winning information command transmitted when a display result is derived to the variable display device 2 in the game (that is, at the end of one game), the continuous effect is developed to the next stage. The development notification effect is performed on the liquid crystal display 4 and the value of the effect state flag is updated to 1.

  If the state of the production state flag is 1 at the start of the next game (that is, at the time of receiving the winning status notification command), the liquid crystal display 4 displays the development start production that is a continuous production developed to the next stage. At the end of the game (i.e., at the time of receiving a winning information command), a bonus confirmation notification effect indicating that a bonus is won or a loss confirmation notification effect indicating whether or not a bonus winning flag is actually set. Is performed in the liquid crystal display 4.

  Of course, when winning a small role or replay with a winning information command, the production state flag remains set to 1, and the continuous production continues until the next game without performing the bonus finalization announcement effect or losing finalization announcement production. The continuation effect is performed on the liquid crystal display 4. In the case where the continuous effect is performed, at the end of the next game (if the small role or replay is not won), a bonus confirmation notification effect or a loss confirmation notification effect is performed.

  After the bonus confirmation announcement is made, the number of games until the type of bonus that has been won is announced according to the result of the type immediate announcement lottery, and it is confirmed if it is decided to announce in the next game 2 is set as the value of the notification counter, and 6 is set as the value of the final notification counter when it is determined to notify after 5 games. The value of the final notification counter is decremented by 1 when the game is 2 or more, and when the value is 1, the winning bonus type is notified on the liquid crystal display 4 It becomes.

  In addition, except for the case where the continuous production is being executed, the bonus winning flag is set, and the symbol of the type of the winning bonus is a part of the display form of the winning prize when the second reel is stopped. When the symbol to be reproduced is derived on the effective line of the variable display device 2), a special tempering sound different from the sound output when the normal reel is stopped may be output from the speaker 7.

  In order to output this special tempering sound, the RAM 122 is further provided with an area for storing three reel stop commands transmitted in one game. The CPU 121 determines by lottery whether to output the special tempering sound based on the reel stop command, the winning status notification command, and the state of the effect state flag stored in the RAM 122, and outputs the special tempering sound from the speaker 7. It is supposed to let you.

  Hereinafter, a gaming operation in the slot machine 1 according to this embodiment will be described. In the following description, the term “game” means, in a narrow sense, from the operation of the start lever 11 until the reels 3L, 3C, 3R are stopped. However, when a game is played, the number of bets before the operation of the start lever 11 is set, and medals are paid out and the game state is shifted after the reels 3L, 3C, 3R are stopped. Is also included in the “game” in a broad sense. Note that the transmission of commands from the game control board 101 to the effect control board 102 is not directly related to the present invention, and thus the description thereof is omitted.

  FIG. 8 is a flowchart showing processing for one game executed by the CPU 111 of the game control board 101. This process is also executed after the power is turned on and a predetermined boot process is performed, or immediately after the setting is changed by operating the setting switch 91. When the process of one game is started, first, an initial process including a process of clearing a predetermined area of the RAM 112 is performed (step S1).

  Next, the number of bets is set by operating one BET button 14 or MAXBET button 15 or by inserting medals from the medal insertion slot 13, and operating the start lever 11 to substantially change the game. BET processing for instructing start is performed (step S2). Here, when the gaming state is a regular bonus (including the case where the bonus is provided during the big bonus), if the bet number is set to 1 (the bet number larger than this is not set), the start lever 11 is operated effectively. It becomes. In other game states, the start lever 11 becomes effective after 3 is set as the bet number. Further, if the player has won a replay in the previous game, the same number of bets as in the previous game (3 in this embodiment) is automatically set by the replay flag (the replay flag is erased at this stage) and remains as it is. The start lever 11 becomes effective.

  When the number of bets is set by the BET process and the start lever 11 is operated, a random number for internal lottery is extracted, and winning to each combination determined according to the gaming state is allowed based on the extracted random number value A lottery process for determining whether or not to perform is performed (step S3). In this lottery process, a winning flag is set in the RAM 112 based on each lottery result. Details of the lottery process will be described later.

  When the lottery process ends, a reel fluctuation start process is performed (step S4). In the reel fluctuation start process, the reels 3L, 3C, and 3R in the previous game are processed on the condition that a predetermined time (for example, 4.1 seconds) has elapsed from the start of rotation of the reels 3L, 3C, 3R. The motors 3ML, 3MC, and 3MR are driven to start rotation of all the left, middle, and right reels 3L, 3C, and 3R. Thereby, the symbols are variably displayed on the variable display device 2. Here, if the predetermined time has not elapsed since the start of rotation in the previous game, the process waits for rotation to start. Also, the timing of one game timer for the next game is started.

  Thereafter, reel fluctuation stop processing is performed (step S5). In the reel fluctuation stop process, after a predetermined condition is established from the start of reel rotation (the reference position is detected by the reel sensors 3SL, 3SC, 3SR after the rotation speed reaches a certain speed), the stop buttons 12L, 12C , 12R are enabled, and each is operated by the player, thereby stopping the driving of the reel motors 3ML, 3MC, 3MR and stopping the rotation of the reels 3L, 3C, 3R according to the setting state of the winning flag. Details of the reel fluctuation stop process will be described later.

  When the driving of each of the reels 3L, 3C, 3R is stopped, in the display mode at the time of stopping, is any of the above-mentioned role symbols derived and displayed on the active line corresponding to the bet number set in the BET process in step S2 A winning determination process for determining whether or not is performed (step S6). If it is determined in this winning determination process that a winning combination has been won, various processes corresponding to the winnings generated on the game control board 101 are performed. Details of the winning determination process will be described later.

  When the winning determination process ends, a payout process is performed (step S7). In the payout process, the credit is increased by the number of payouts set in the winning determination process. However, when the number of credits accumulated as data reaches 50, the hopper motor 82 is driven to pay out an excess number of medals from the medal payout slot 71. Various processes not related to winning are also performed (including processes related to erasure of winning flags other than big bonus and regular bonus winning flags, and termination of big bonus and regular bonus). Then, the process for one game ends, and the process for the next one game starts.

  Next, the lottery process in step S3 will be described in detail. FIG. 9 is a flowchart showing in detail the lottery process executed by the CPU 111 in step S3. In the lottery process, first, a random number acquisition process whose details will be described later is performed. In this random number acquisition process, a random number value for internal lottery is acquired based on the random number generated by the random number generation circuit 115 (step S101).

  Next, in accordance with the current gaming state, the combinations registered in the winning combination table by gaming state in FIG. 4A are sequentially read (step S102). Here, it is determined whether or not the type of the combination read out is either a regular bonus or a big bonus (1) to (3) (step S103). If the type of the read combination is neither the regular bonus nor the big bonus (1) to (3), the process proceeds to step S105 as it is. If the type of the read role is one of the regular bonus and the big bonus (1) to (3), the regular bonus winning flag, the big bonus (1) winning flag, the big bonus ( 2) A winning flag or a big bonus (3) A winning flag is already set, and it is determined whether or not it is carried over without winning based on the winning flag (step S104).

  If the regular bonus winning flag, the big bonus (1) winning flag, the big bonus (2) winning flag, or the big bonus (3) winning flag is already set, the process returns to the process of step S102, and the winning combination according to the gaming state is further performed. The next combination registered in the table is read out (the regular bonus, the big bonus (1), the big bonus (2), and the big bonus (3) are registered first in the winning combination table by gaming state). (So, this does not end the lottery process). Regardless of the type of read role, regular bonus, big bonus (1), big bonus (2), big bonus (3), regular bonus winning flag, big bonus (1) winning flag, big bonus (2) winning If neither the flag nor the big bonus (3) winning flag is set, the process proceeds to step S105.

  In step S105, the BET number set in step S2 is further read, and the setting status of the common flag is acquired in the role-specific table of FIG. 4B for the role and the role corresponding to the read BET number. As a result, it is determined whether or not a common flag is set for the combination and the BET number (step S106).

  If the common flag is set, the number of determination values stored in the address registered in the role-specific table of FIG. 4B is acquired for the role and the BET number (step S107). Then, the process proceeds to step S109. If the common flag is not set, the setting value set in the RAM 112 is read and stored in the address registered in the role-specific table corresponding to the setting value read for the role and the BET number. The number of determination values is acquired (step S108). Then, the process proceeds to step S109.

  In step S109, the number of determination values acquired in step S107 or S108 is added to the internal lottery random 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 S110). If an overflow occurs, a winning flag for the combination is set in the RAM 112 (step S111). Then, the process proceeds to step S113.

  If no overflow has occurred, it is determined whether there is a combination that has not yet been processed among the combinations determined for the gaming state (step S112). If there is a combination that has not yet been processed, the process returns to step S102, and the process continues with the next combination registered in the winning combination table according to gaming state as the processing target. If there is no combination not to be processed, the process proceeds to step S113.

  In step S113, a winning status notification command capable of specifying the setting status of the winning flag and the current gaming state (regular bonus, big bonus (until regular bonus and small role game) or normal gaming state) is generated, It transmits to the production 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 S101 will be described in detail. FIG. 10 is a flowchart showing in detail the random number acquisition process executed by the CPU 111 in step S101. In the random number acquisition process, first, interrupt to the CPU 111 is prohibited (step S201). Next, a sampling command is output to the sampling circuit 116, the random number generated by the random number generation circuit 115 is latched, and the value of the latched random number is input from the I / O port 114 and extracted. The random number value extracted from the random number generation circuit 115 is stored in the general-purpose register 111GR (step S202).

  Next, the lower byte value and upper byte value of the random number stored in the general-purpose register 111GR are exchanged with each other using the work area of the RAM 112 (step S203). Next, the value of the random number stored in the general-purpose register 111GR is ANDed with 8080h (step S204). Further, the upper byte (15th to 8th bits) is shifted downward by 1 bit, and 1 is inserted into the empty 15th bit. At this time, the value stored in the general-purpose register 111GR is acquired as a random number for internal lottery and stored in a predetermined area of the RAM 112 (step S205). Then, after permitting the interrupt prohibited in step S201 (step S206), the random number acquisition process is terminated, and the process returns to the flowchart of FIG.

  Next, the reel fluctuation stop process in step S5 will be described in detail. FIG. 11 is a flowchart showing in detail the reel fluctuation stop process executed by the CPU 111 in step S5. First, after the rotation of the reels 3L, 3C, and 3R reaches a constant speed, there is a predetermined condition that enables the reels 3L, 3C, and 3R to stop the reels 3L, 3C, and 3R to detect the reference position after all. It is determined whether or not it is established (step S301).

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

  In step S303, it is determined whether or not the left stop button 12L is operated depending on whether or not the detection signal of the stop switch 42L is input. Here, even if the left stop button 12L is physically operated, if the operation has already been disabled, the stop button 12L is regarded as not being operated. If the left stop button 12L has not been operated, the process proceeds directly to step S307.

  If it is determined that the left stop button 12L is operated, the left stop button 12L is disabled thereafter, and the operation enable lamp 63L is turned off (step S304). The symbols to be derived according to the setting status of the winning flags for each combination in the RAM 112 and the types of symbols displayed on the variable display device 2 for the left reel 3L at the timing when the player operates the stop button 12L. And the rotation of the left reel 3L is stopped (step S305). Further, a reel stop command capable of specifying that the reel stopped this time is the left reel 3L and a symbol derived to the left reel 3L is generated and transmitted to the effect control board 102 (step S306). Then, the process proceeds to step S307.

  In step S307, it is determined whether or not the middle stop button 12C is operated depending on whether or not the detection signal of the stop switch 42C is input. Here, even if the middle stop button 12C is physically operated, if the operation has already been disabled, it is considered that the stop button 12C has not been operated. If the middle stop button 12C is not operated, the process proceeds to step S311.

  If it is determined that the middle stop button 12C is being operated, the middle stop button 12C is invalidated thereafter, and the operation valid lamp 63C is turned off (step S308). The symbols to be derived according to the setting status of the winning flags for each combination in the RAM 112 and the types of symbols displayed on the variable display device 2 for the inner reel 3C at the timing when the player operates the stop button 12C. And the rotation of the inner reel 3C is stopped (step S309). Further, a reel stop command capable of specifying the reel that has been stopped this time is the inner reel 3C and the symbol derived to the inner reel 3C is generated and transmitted to the effect control board 102 (step S310). Then, the process proceeds to step S311.

  In step S311, whether or not the right stop button 12R is operated is determined based on whether or not the detection signal of the stop switch 42R is input. Here, even if the right stop button 12R is physically operated, if the operation has already been disabled, the stop button 12R is regarded as not being operated. If the right stop button 12R has not been operated, the process proceeds directly to step S315.

  If it is determined that the right stop button 12R is being operated, the right stop button 12R is subsequently disabled, and the operation enable lamp 63R is turned off (step S312). The symbols to be derived according to the setting status of the winning flags for each combination in the RAM 112 and the types of symbols displayed on the variable display device 2 for the right reel 3R at the timing when the player operates the stop button 12R. And the rotation of the right reel 3R is stopped (step S313). Further, a reel stop command capable of specifying that the reel stopped this time is the right reel 3R and a symbol derived to the right reel 3R is generated and transmitted to the effect control board 102 (step S314). Then, the process proceeds to step S315.

  In step S315, it is determined whether all the left, middle, and right reels 3L, 3C, 3R are stopped. If any one of the reels 3L, 3C, 3R is not stopped, the process returns to step S303. When all of the reels 3L, 3C, and 3R are stopped, the reel fluctuation stop processing is ended and the process returns to the flowchart of FIG.

  Next, the winning determination process in step S6 will be described in detail. FIG. 13 is a flowchart showing in detail the winning determination process executed by the CPU 111 in step S6. First, it is determined whether or not the display mode (red 7-red 7-red 7) of the big bonus (1) is derived on any active line (step S401). If the display mode of the big bonus (1) has been derived, the big bonus medium flag is set in the RAM 112 and the big bonus (1) winning flag set in the RAM 112 is deleted (step S402). Then, the process proceeds to step S421.

  When the display mode of the big bonus (1) is not derived, it is determined whether or not the display mode (white 7-white 7-white 7) of the big bonus (2) is derived on any active line. (Step S403). If the display mode of the big bonus (2) is derived, the big bonus medium flag is set in the RAM 112 and the big bonus (2) winning flag set in the RAM 112 is deleted (step S404). Then, the process proceeds to step S421.

  When the display mode of the big bonus (2) is not derived, it is determined whether the display mode (blue 7-blue 7-blue 7) of the big bonus (3) is derived on any active line. (Step S405). If the display mode of the big bonus (3) is derived, the big bonus medium flag is set in the RAM 112 and the big bonus (3) winning flag set in the RAM 112 is deleted (step S406). Then, the process proceeds to step S421.

  If the display mode of the big bonus (3) is not derived, it is determined whether or not the display mode of the regular bonus (BAR-BAR-BAR) is derived on any active line (step S407). If the display mode of the regular bonus has been derived, the regular bonus medium flag is set in the RAM 112 and the regular bonus winning flag set in the RAM 112 is erased (step S408). Then, the process proceeds to step S421.

  If the display mode of the regular bonus is not derived, it is determined whether or not the JACIN display mode (watermelon-JAC-JAC) is derived on any active line (step S409). If the display mode of JACIN is derived, a regular bonus medium flag is set in the RAM 112. In this case, the regular bonus medium flag is also set over the big bonus medium flag (step S410). Then, the process proceeds to step S421.

  When the display mode of JACIN is not derived, it is determined whether or not the display mode of watermelon (watermelon-watermelon-watermelon) is derived on any effective line (step S411). If the display mode of the watermelon is derived, 15 is set as the planned payout number of medals (step S412). Then, the process proceeds to step S421.

  If the display mode of the watermelon has not been derived, it is determined whether or not the display mode of the bell (bell-bell-bell) has been derived on any effective line (step S413). If the bell display mode is derived, 15 (regular bonus) or 8 (normal game state or small role game) is set as the planned payout number of medals according to the bet number set in step S2 ( Step S414). Then, the process proceeds to step S421.

  If the bell display mode is not derived, it is determined whether or not the cherry display mode (cherry-ANY-ANY) is derived on any effective line (step S415). If the display mode of cherry is derived, 4 is set as the expected payout number of medals (step S416). Then, the process proceeds to step S421.

  If the cherry display mode is not derived, it is determined whether or not the JAC display mode (bell-JAC-JAC) is derived on any of the effective lines (step S417). If the display mode of JAC is derived, 15 is set as the planned payout number of medals (step S418). Then, the process proceeds to step S421.

  If the JAC display mode is not derived, it is determined whether or not the replay display mode (JAC-JAC-JAC) is derived on any of the effective lines (step S419). If the replay display mode is derived, a replay flag is set in the RAM 112 (step S420). This replay flag is deleted when the bet number is automatically set in the next game. Then, the process proceeds to step S421. If the display mode of replay is not derived, the process proceeds to step S421 as it is.

  In step S <b> 421, a winning information command indicating the winning combination is generated and transmitted to the effect control board 102 when there is a winning or not and when there is a winning. Furthermore, if the small role winning flag, the replay winning flag, and the JACIN winning flag are set in the RAM 112, these are deleted (step S422). Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  In the repetition of the game as described above, the CPU 111 of the game control board 101 performs a transition of the game state between the normal game state, the regular bonus, and the big bonus, and controls the effects according to the progress of the game. It is transmitted to the substrate 102. On the other hand, the CPU 121 of the effect control board 102 performs an original effect based on the command received from the game control board 101. Hereinafter, processing executed by the CPU 121 of the effect control board 102 to perform various effects (particularly effects related to notification of setting of the bonus winning flag) will be described.

  13 and 14 are flowcharts showing command reception standby 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 the command sent from the game control board 101 has been received (step S501). When any command is received from the game control board 101, the type of the received command is determined (step S502).

  If the received command type is the winning status notification command transmitted in step S113, the reel stop command stored in the RAM 122 in the previous game is deleted, and the winning status notification command is stored in a predetermined area of the RAM 122. (Step S503). Next, it is determined whether the received winning status notification command indicates that the current gaming state is a normal gaming state (step S504). If it does not indicate that the game state is normal, the process returns to step S501.

  If it indicates that the game state is normal, whether or not the value of the fixed notification counter in the RAM 122 is 1 or more, that is, whether or not the bonus winning flag is set and the bonus fixed notification effect has already been performed. Is determined (step S505). When the value of the fixed notification counter in the RAM 122 is not 1 or more (that is, 0), the bonus fixed notification effect is not yet performed. In this case, the state of the effect state flag in the RAM 122 is 1. It is determined whether or not (step S506).

  If the state of the effect state flag is not 1 (the state of the effect state flag is never 2 and is always 0), the continuous effect has not yet started, so the winning status notification stored in the RAM 122 A continuous effect lottery is performed with a different probability depending on whether or not the command indicates the setting of the bonus winning flag (step S507). Here, the winning probability of the continuous effect lottery can be, for example, 30% when the bonus winning flag is set and 1% when the bonus winning flag is not set.

  It is determined whether or not it has been decided to perform a continuous effect as a result of the continuous effect lottery (step S508). In the case where a continuous effect is performed according to the lottery result, the state of the effect state flag in the RAM 122 is updated to 2 (step S509). Furthermore, the start effect in the continuous effect is performed on the liquid crystal display 4 (step S510). Then, the process returns to step S501. If the continuous production is not performed due to the lottery result, the process directly returns to step S501.

  If the state of the effect state flag is 1, the development notification effect or the continuous effect for connecting the continuous effect to the next game at the end of the previous game is performed on the liquid crystal display 4. In this case, the development start effect for introducing the result notified at the end of the continuous effect (losing confirmation notification effect or bonus confirmation notification effect) is performed on the liquid crystal display 4 (step S511). Then, the process returns to step S501.

  If it is determined in step S505 that the value of the final notification counter is 1 or more, whether the value of the final notification counter is 1, that is, not only the bonus final notification effect but also the type of bonus. It is determined whether or not notification is also made (step S512). If the value of the final notification counter is 1, since the type of bonus that has already been won is also notified, the process directly returns to step S501.

  If the value of the fixed notification counter is not 1, the value of the fixed notification counter is decremented by 1 (step S513). As a result of the subtraction, it is determined whether or not the value of the final notification counter has become 1 (step S514). If the value of the final notification counter is not 1, it is not yet time to notify the bonus type, and the process directly returns to step S501. When the value of the final announcement counter is 1, the liquid crystal display 4 displays whether the regular bonus, the big bonus (1), the big bonus (2) or the big bonus (3) is won. The player is notified (step S515). Then, the process returns to step S501.

  If the received command type is the reel stop command transmitted in steps S306, S310, and S314, the reel stop command is stored in a predetermined area of the RAM 122. Since the reel stop command is sent three times in one game, two reel stop commands are stored in the RAM 122 when the second reel is stopped, and three reel stop commands are stored when the third reel is stopped. (Step S516).

  Next, it is determined whether or not the state of the effect state flag in the RAM 122 is 0, that is, whether or not the current continuous effect is not being executed (step S517). If the value of the effect state flag is not 0, the continuous effect is being executed, and the process directly returns to step S501. If the state of the continuous effect flag is 0, it is determined whether or not the winning status notification command stored in the RAM 122 indicates the setting of the bonus winning flag (step S518). If the bonus winning flag is not set, the process returns to step S501.

  If the bonus winning flag is set, whether the reel stop command received this time corresponds to the stop of the second reel, and the bonus symbol of the type selected by the stop of the second reel has been tempered. It is determined based on the winning status notification command and the reel stop command stored in the RAM 122 (step S519). If the bonus symbol of the selected type has not been tempered, the process directly returns to step S501.

  If the bonus symbol of the selected type is a temper, a special temper lottery for determining whether or not to output a special tempering sound for notifying that type of bonus winning is performed (step S520). As a result of the lottery, it is determined whether or not it is determined that the special tempering sound is to be output (step S521). If the special tempering sound is not output as a result of the lottery, the process directly returns to step S501. When outputting the special tempering sound based on the result of the lottery, the special tempering sound different from that at the time of the normal reel stop is outputted from the speaker 7 (step S522). Then, the process returns to step S501.

  If the received command type is the winning information command transmitted in step S421, it is determined whether or not the winning information command indicates that any type of bonus has been won (step S523). ). If it indicates that any kind of bonus has been won, the state of the effect state flag in the RAM 122 is updated to 0 (if it was originally 0, it is not changed), and the value of the final notification counter in the RAM 122 is set to 0. (Step S524). Then, the process returns to step S501.

  If the received winning information command indicates that no bonus of any kind has been won, whether or not the state flag of the RAM 122 is 2, that is, the continuous effect is started at the start of the current game. It is determined whether or not it has been (step S525). If the state of the effect state flag is 2, a development notification effect for connecting to the next game as a continuous effect is performed on the liquid crystal display 4 (step S526), and the state of the effect state flag is updated to 1 (step S527). . Then, the process returns to step S501.

  If the state of the effect state flag is not 2, it is further determined whether or not the state of the effect state flag is 1 (step S528). If the state of the effect state flag is not 1, that is, the state is 0, the continuous effect is not being executed, and the process directly returns to step S501. When the state of the effect state flag is 1, it is further determined whether or not the received winning information command indicates a winning combination or a replay winning (step S529).

  If the winning combination of the small role or the replay is shown, it is not known from the display result of the variable display device 2 whether the bonus is won or not. Therefore, a continuous effect indicating that the continuous effect is continued until the next game is performed on the liquid crystal display 4 without performing the effect of notifying the bonus winning or the effect of notifying the bonus loss (step S530). Here, the process returns to step S501 without updating the state of the effect state flag.

  If neither winning of a small role nor replay is indicated, it is determined whether or not the winning status notification command stored in the RAM 122 indicates that the bonus winning flag is set (step S531). If it indicates that the bonus winning flag is not set, the liquid crystal display 4 performs a loss confirmation notification effect definitely indicating the bonus loss as a display of the final result of the continuous effect (step S532). Further, the state of the effect state flag is updated to 0 (step S533). Then, the process returns to step S501.

  If the winning status notification command stored in the RAM 122 indicates that the bonus winning flag is set, the liquid crystal display 4 performs a bonus final notification effect that definitely indicates the bonus winning as a display of the final result of the continuous performance. (Step S534). Further, the state of the effect state flag is updated to 0 (step S535). Furthermore, a type immediate notification lottery is performed to determine whether the type of bonus that has been won is notified immediately at the start of the next game or at the start of the game after five games (step S536).

  As a result of the lottery, it is determined whether or not it is decided to immediately notify the type of bonus that has been won at the start of the next game (step S537). If notification of the type of bonus that has been won based on the lottery result is made immediately at the start of the next game, 2 is set as the value of the final notification counter in the RAM 122 (step S538), and the process of step S501 is performed. Return. If notification of the type of bonus that has been won based on the lottery result is made at the start of 5 games, 6 is set as the value of the final notification counter in the RAM 122 (step S539), and the process returns to step S501.

  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 S540). Thereafter, the process returns to step S501.

  Hereinafter, the execution aspect of the continuous effect performed in the liquid crystal display 4 is demonstrated based on a specific example. FIGS. 15A to 15F are diagrams specifically illustrating the execution mode of the continuous effect in the liquid crystal display 4. Here, the case where the big bonus (1) winning flag is set and continuous production is started is taken as an example.

  It is assumed that when the player operates the start lever 11, the player wins the continuous effect lottery with the bonus winning flag set by carrying over from the previous game or winning the internal lottery. Here, the start effect in the continuous effect is performed, and the player-side character 301 appears and is displayed on the liquid crystal display 4 as shown in FIG.

  Next, it is assumed that all of the stop buttons 12L, 12C, and 12R are operated by the player, and the display result is derived to the variable display device 2. If there is no bonus winning according to the display result displayed here, the development notification effect in the continuous effect is performed, and as shown in FIG. 15 (b), the enemy character 302 is also added in addition to the player-side character 301. Appears and displayed on the liquid crystal display 4.

  When the player operates the start lever 11 in the next game, the continuous effect is performed here, and the bonus confirmation notification effect or the loss confirmation notification effect is not yet performed. Here, the development start effect in the continuous effect is performed, and the start of the battle between the player-side character 301 and the enemy character 302 is displayed on the liquid crystal display 4 as shown in FIG.

  Next, it is assumed that all of the stop buttons 12L, 12C, and 12R are operated by the player, and the display result is derived to the variable display device 2. According to the display result displayed here, it is assumed that neither a bonus winning nor a small role or replay has been won. Here, since the bonus winning flag is set, the bonus final announcement effect in the continuous effect is performed, and as shown in FIG. 15D, the player character 301 wins the battle and wins the bonus. This is displayed on the liquid crystal display 4.

  Then, when the player operates the start lever 11 in the next game when the immediate notification effect lottery is won, and when the player operates the start lever after 5 games when the player loses the immediate notification effect lottery, As shown in FIG. 15 (e), the fact that the big bonus (1) has been won is displayed on the liquid crystal display 4, and the player is informed of the type of bonus that has been won.

  Further, when the player has operated all of the stop buttons 12L, 12C, and 12R in the game in which the development start effect is performed as shown in FIG. 15C, and the display result is derived to the variable display device 2, Assume that you have won a small role or a replay. Here, the continuous effect is performed without ending the continuous effect, and the liquid crystal display 4 indicates that the battle between the player character 301 and the enemy character 302 continues as shown in FIG. Is displayed.

  It should be noted that the continuous effect starts when no bonus winning flag of any kind is set, and the stop button 12L, 12C, 12R is played by the player in the game in which the development start effect is performed as shown in FIG. 15 (c). If all of the above are operated and the display result is derived on the variable display device 2, it is assumed that neither the small role nor the replay has been won. Bonus loss is displayed on the liquid crystal display 4.

  As described above, in the slot machine 1 according to this embodiment, four types of bonuses are defined, the regular bonus, the big bonus (1), the big bonus (2), and the big bonus (3). It becomes a target for internal lottery, and a separate winning flag is set. Further, the display modes for winning the regular bonus, the big bonus (1), the big bonus (2), and the big bonus (3) are different from each other, and the operation procedures of the stop buttons 12L, 12C, and 12R for winning each are also mutually different. It is exclusive.

  In addition, a continuous effect that continues for two games is performed with a relatively high probability when the bonus winning flag is set and with a certain low probability even when the bonus winning flag is not set. Here, when the continuous performance is performed, the possibility of winning the bonus is higher than when it is not.

  Here, in the game in which the continuous production is started, for example, even if the player operates the stop buttons 12L, 12C, and 12R at a timing when the player can win the big bonus (1), the player has not won the big bonus (1). That said, other types of bonuses may still be won. Even if the stop button 12L, 12C, 12R is operated at the timing when the big bonus (2) can be won in the second game of the continuous production, the regular bonus or big bonus is still not won because the big bonus (2) is not won. There is a possibility of winning (2).

  In this way, the operation timing of the winning flag and the stop buttons 12L, 12C, 12R is variable as long as the reach is not derived by increasing the number of bonuses that are mutually exclusive to 4 types and increasing the number of games in which the continuous production continues to 2 From the display result of the display device 2, the presence / absence of the bonus winning is not determined while the continuous effect is continued, and the continuous effect is not made meaningless. In addition, this makes it possible to give the player a continuous sense of expectation while the continuous performance is continued, and to improve the interest of the game.

  Even when a continuous effect is being executed, if any type of bonus is won and the stop button 12L, 12C, 12R is operated at a timing when the bonus can be won, the bonus can be won. Is possible, so there is no loss to the player. Even when the bonus winning flag has been carried over from the previous game, a small role or replay lottery will be held, but even if the bonus winning flag is set on top of the bonus winning flag, the former win Therefore, if the operation timing of the stop buttons 12L, 12C, and 12R is appropriate, a bonus can be won immediately, and the player will not be stressed without ever winning the bonus.

  In addition, when the continuous production is ended at the end of the second game from the start of the continuous production, the bonus final announcement effect or the lost final announcement production is informed to the player so that the continuous production has ended. There is no need for the player to continue to waste time. When the bonus final announcement effect is performed at the end of the continuous performance, the type of the winning bonus may be notified at the start of the next game or at the start after five games. . As described above, since there are a plurality of notification timings, a variety of production modes can be obtained, and the interest of the game can be improved.

  When the bonus type is announced at the start of the next game of the bonus final announcement effect, the player can operate the stop buttons 12L, 12C, and 12R by determining the type of bonus that the player should aim for winning. , Make the game easier to progress. On the other hand, if the bonus type is not announced until after five games of the bonus confirmation announcement effect, it may occur that the player does not yet know the type of bonus that has been won, so that the interest of the game can be improved. However, in any case, after 5 games since the bonus confirmation notification effect is performed, the type of the winning bonus is notified, so the stop buttons 12L, 12C, and 12R can always be operated at an appropriate timing. Even if it is a difficult beginner, there is no waste of operating the stop buttons 12L, 12C, and 12R aiming for bonuses that are not actually won indefinitely, so that a large loss is not caused to the player. it can.

  By the way, the continuous production basically ends in two games from the start, but if winning a small role or replay in the second game of the continuous production, the continuous production is continued until the next game. . Even when winning a small role or replay in a game in which the continuous production has been continued, the continuous production is continued until the next game. In a game that has won a replay or small role, the player will never know whether or not the bonus has been won anyway. In such a case, the continuous production will be continued for a longer period of time. The stage can give the player a sense of expectation and improve the fun of the game.

  In addition, notification of information regarding whether or not a bonus winning is set is performed not only by a continuous effect performed in the liquid crystal display 4, but also by a reach eye or a chance eye derived as a display result of the variable display device 2. . Therefore, even if the liquid crystal display 4 or the control unit 120 of the effect control board 102 that controls the liquid crystal display 4 does not operate normally due to a failure or the like, the display result derived to the variable display device 2 is realized. The game can be continued according to reach and chance.

  Here, not only the common reach that is derived regardless of the type of the winning bonus, but also the individual reach that is derived according to the type of the winning bonus. The chances are not only common chances with the same probability derived according to the type of winning bonus, but also individual chances with different probabilities derived according to the type of winning bonus. is there. Such derivation of individual reach and individual chances also allows the player to proceed with the game without waste according to the type of bonus that has been won.

  In addition, the type of bonus that has been won is also notified by the output of a special tempering sound. For example, if a special tempering sound is output when “BAR” is tempered on the active line when the second reel is stopped, it is understood that the regular bonus is won. Such a special tempering sound also gives the player a sense of expectation, and a rich variety of effects can further enhance the interest of the game. However, since the special tempering sound is not output when the continuous production is being executed, it is possible to prevent the execution of the continuous production from being meaningless.

  In addition, the types of winning combinations in this slot machine 1 include small roles with payout of medals, special roles with transition of gaming state, and re-playing roles that require no medals to be consumed in the next game. Is stipulated. The special role is accompanied by a transition of the game state and depends on the game state at that time, so it cannot be said to be a basic role. The playability of slot machines is not just playing a game, but the player earns medals based on the game results, so the small role that involves paying out medals by winning a prize is the most basic role. It can be said. Here, there are watermelon, bell, cherry, and JAC as types of small roles, but in addition to JAC that wins with a small probability in the regular bonus, it is determined as a type of winning combination in any gaming state. ing. 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.

  If you win a big bonus (1)-(3) in the normal gaming state, the gaming state will be transferred to a big bonus that wins JACIN with a transition to the regular bonus with a relatively high probability (winning because there is no missing) The The big bonus ends when the number of medals paid out reaches 480 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 game state from the small role game to the regular bonus in the big bonus is configured by a combination of “watermelon-JAC-JAC” and is not used as a display mode of other roles. It is. For this reason, the relationship between the display mode derived to the variable display device 2 and the winning combination is clarified, and the game is easy to understand for the player.

  The rotation of the reels 3L, 3C, and 3R is stopped within the range of the maximum stop delay time of 190 milliseconds after the operation of the stop buttons 12L, 12C, and 12R is detected by the stop switches 42L, 42C, and 42R. Since 4 frames can be drawn during this time, the symbols to be stopped can be selected from a range of 5 frames, so that when the winning part of the bell is won, this is not missed. 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 referenced from the determining table. Stored in the address. In the role table, the number of medals to be paid out when winning for each role is also registered.

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

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

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

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

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

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

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

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

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

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

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

  In the above embodiment, the regular bonus, the big bonus (1), the big bonus (2), the big bonus (2), which are won at the start of the next game after the bonus confirmation notification effect or at the start after five games, It was announced which of the big bonus (3). Of course, there are four types of bonuses when the internal lottery is considered as a standard, but when the gaming state is considered as a standard, the bonus can be divided into two groups: a regular bonus and a big bonus. Since all of the big bonuses (1) to (3) are accompanied by the transition of the game state to the same big bonus, only the bonus group (here, only the regular bonus or the big bonus) is announced. Also good. When it is announced that the big bonus is won here, when the predetermined number of games is exhausted, it is possible to notify whether it is any of the big bonuses (1) to (3). Good.

  When the big bonus is announced after the bonus final announcement, the bonus type may not be announced there. Furthermore, the bonus type that has been won after the bonus final announcement effect is not necessarily notified, and it may be notified or not notified at a predetermined rate. In this way, various kinds of announcements with different advantages in games can be made so that the type of bonus can be completely understood, only the difference in value can be understood, or it can be completely unknown. , You can improve the fun of the game.

  The bonus groups can be classified according to differences in game playability (the above-mentioned regular bonus is only a small role game, but the big bonus is a small role game + big bonus). If the bonuses are the same, even if there are differences in the bonus termination conditions (for example, Big Bonus (1) pays out 180 cards, Big Bonus (2) pays out 240 cards, Big Bonus (3) It ends with 360 payouts) and can be a bonus belonging to the same group. However, as long as the bonus termination conditions are different, it is not prevented that the bonus belongs to a different group.

  Even if there is a difference in the gaming state to be transferred after the bonus is over (for example, the big bonus (1) returns to the normal gaming state after the end of the bonus, but after the big bonus (2) is over, the AT is set by the predetermined number of games. Added, RT is added for a predetermined number of games after the end of the big bonus (3)), and the bonuses belong to the same group. However, bonuses belonging to different groups may be used as long as the game state is controlled after the bonus ends.

  Furthermore, the bonuses can be grouped according to the difference in the winning probability of the small role in the internal lottery or the difference in the number of medals to be paid out when winning the small role. Furthermore, bonuses can be grouped by arbitrarily combining differences in game playability, end conditions, and added game states.

  In the above embodiment, the type of bonus is not notified in the game in which the bonus confirmation notification effect is performed, and the type of bonus that is won at the start of the next game is notified at the earliest. On the other hand, up to the type (or value) of the bonus that is won in the bonus confirmation notification effect may be notified. Even when the type of bonus (or value) that has been won since the next game where the bonus confirmation notification is performed is announced, the timing is not at the start of the game but at the end of the game (i.e., The type of bonus may be announced at the timing when the display result is derived and the winning information command is transmitted to the variable display device 2).

  In the above embodiment, it is determined whether or not a bonus winning flag is set in a game that has not won a small role or a replay after the second game since the start of the continuous effect, and thereby a bonus confirmation notification effect or It was supposed to execute the finalization notice announcement. That is, even if the bonus is not won in the game where the continuous production has started, if the bonus is won in the game when the continuous production has ended, the bonus confirmation notification production is performed. On the other hand, at the start of the continuous production, the result (whether it will be the bonus confirmation announcement production or the loss confirmation announcement production) is determined in advance, and if the bonus is not won at the start of the continuous production, It is good also as what performs a lose decision announcement effect.

  In the above embodiment, there are four types of bonuses: regular bonus, big bonus (1), big bonus (2), and big bonus (3), and the number of continuous games of continuous production is two games (however, It was extended when winning the small role or replay after the second game. However, the relationship between the type of bonus and the number of continuous games for continuous production is not limited to this, and the type of bonus for which the winning flag and stop operation timing are exclusive is more than the number of continuous games for continuous production. Good.

  In addition, the stop operation timings need not be exclusive for all types of bonuses, and some of them may have overlapping stop operation timings. Of course, for each type of bonus, the operation timing of the stop buttons 12L, 12C, and 12R for winning is required to be exclusive with at least one other type of bonus. Here, the number of continuous games in the continuous effect may be equal to or less than the type of bonus whose stop operation timing is exclusive.

  For example, for the big bonus (2) and the big bonus (3), the stop operation timing is exclusive for any other type of bonus, but the stop operation timing overlaps for the big bonus (1) and the regular bonus. Think about the case. As a symbol arrangement in such a case, for each of the reels 3L, 3C, 3R, there is a place where “BAR” and “Red 7” are arranged within 5 frames, and any of the reels 3L, 3C, 3R As for “blue 7” or “white 7”, there are places where “BAR”, “red 7”, “white 7” or “blue 7” are not arranged within 5 frames. Here, since there are three types of bonuses with exclusive stop operation timing, the number of games in which the continuous production continues is three games or less.

  In the above embodiment, the content executed as a continuous effect is the same regardless of the type of bonus of regular bonus, big bonus (1), big bonus (2), or big bonus (3). Met. On the other hand, a plurality of types of continuous effects are prepared, and, for example, when a regular bonus is won as in the individual chance derived as a display result of the variable display device 2, You may make it perform the continuous production | presentation of a predetermined | prescribed aspect with a higher probability than when winning a kind of bonus. The difference in the aspect of the production according to the type of bonus can be distinguished, for example, by the difference in the color of the appearing character or the action of the character.

  In the above embodiment, the execution of the continuous effect is controlled by the CPU 121 of the effect control board 102 including the determination of whether to perform the continuous effect. However, it is assumed that the CPU 111 of the game control board 101 determines what kind of effect is to be performed as the continuous effect, and a command including the determination result may be performed on the effect control board 102. The CPU 121 of the effect control board 102 can perform an effect directly indicated by a command received as a continuous effect.

  When the CPU 111 of the game control board 101 makes a determination regarding the continuous effect, the CPU 111 can recognize whether or not the continuous effect is being executed. Therefore, when the continuous production is being executed, even if the bonus winning flag is set, it is possible not to derive any reach eyes. It is possible not to output special tempering sound. In this case, it is possible to prevent the player from knowing that the bonus has been won by the reach, and the meaning of the continuous performance can be avoided.

  Here, when the CPU 111 of the game control board 101 decides on the continuous production, when the bonus winning flag is carried over and when a predetermined lottery is won without setting the bonus winning flag. It is possible to control to RT (Replay Time) which makes the winning probability of replay higher than the normal gaming state without changing the winning probability of other roles. The continuous performance can be executed when the gaming state is controlled to RT.

  Instead of simply carrying over the bonus winning flag or winning a predetermined lottery as an opportunity to shift the gaming state to RT, a predetermined display mode (RT symbol) is derived as a display result on the variable display device 2. That can be applied. For example, assuming that the RT symbol can always be derived within the range of the maximum stop delay time of 190 milliseconds from the operation of the stop buttons 12L, 12C, and 12R, if the bonus winning flag is not set in the game in which the bonus winning flag is set, RT symbols can be derived. In a game in which no bonus winning flag is set and no other winning combination is won, an RT symbol can be derived on condition that a predetermined lottery is won.

  In addition, for example, when the winning combination of watermelon is won when the bonus winning flag is set, or when the winning combination of watermelon is won when the bonus winning flag is not set, the gaming state is controlled to RT. can do. In the latter, the gaming state can be controlled to RT on condition that a predetermined lottery is won. The transition to RT may be triggered by a winning of another type of small role, but must be within the maximum stop delay time of 190 milliseconds from the operation of the stop buttons 12L, 12C, 12R. It is preferable that the role is derivable.

  As described above, at least the bonus winning flag is set by controlling the gaming state to RT when the bonus winning flag is set and when the predetermined lottery is won otherwise. In some cases, the chance to win a replay is increased even if the bonus is not won, and the player can expect a bonus win without significantly reducing the player's medals. Note that the RT gaming state may be controlled for a predetermined number of games after the regular bonus ends, but in this case RT may or may not be a continuous performance. .

  In the above embodiment, only the series of continuous effects and the output of the special tempering sound have been described as effects controlled by the CPU 121 of the effect control board 102, but the effects that the CPU 121 can execute are not limited to this. . For example, when a bonus prize is generated or when the bonus is ended, an effect corresponding to each case can be performed. Here, the effect at the time of winning the bonus will vary depending on the type of bonus that has been won, and the effect when the big bonus ends will depend on the net increase (the number of paid-out medals minus the number of all bets) It may be changed. If it is the effect in the liquid crystal display 4, the screen and the words which a character emits can be changed.

  When the start lever 11 is operated, when the bonus winning flag is set, a warning sound having a predetermined mode with a higher probability than that when the bonus winning flag is not set is output from the speakers 7L, 7R, and 7U with a higher probability. It is good. As in the case where the continuous effect is started when the start lever 11 is operated by outputting the warning sound when the start lever 11 is operated, the player is aiming for a bonus prize from the game. Thus, even if the bonus winning flag is set, it is possible to prevent the player from losing money as much as possible.

  In the above embodiment, the gaming state of the slot machine 1 includes a regular bonus and a big bonus (small role game and regular bonus) in addition to the normal gaming state. There were three types of roles for shifting to the big bonus, big bonuses (1) to (3), but only one type for shifting to the regular bonus. On the other hand, there may be only one type of combination for shifting to the big bonus, or multiple types of combinations for shifting to the regular bonus.

  Furthermore, in addition to the normal gaming state, the maximum stop delay time of any one or more of RT, reels 3L, 3C, and 3R described above is shortened (for example, 75 milliseconds (single frame sliding)) and internal lottery The game further includes a gaming state such as a CT (Challenge Time) allowing a small role to be won regardless of the result of the game, and an AT (Assist Time) for notifying a gaming procedure for winning a role with a winning flag set. It may be. In addition to the big bonus and regular bonus described above, the payout rate calculated by the number of medals paid out for the number of medals used for setting the number of bets in any of CT, AT, and RT is set as a normal game. It becomes possible to make it higher than the state (provided that all stop operations are appropriate).

  Even if the transition to CT, RT, and AT is performed based on winning a corresponding role, a role added for that purpose is a special role and not a basic role. Instead of the big bonus (2) and the big bonus (3), a combination that accompanies CT, RT, and AT may be applied. In addition, RT only increases the probability of winning a replay, and the composition of the combination does not change from the normal gaming state. Even if it is AT, the composition of the combination does not change but only the gaming procedure is notified. Even if the CT is not an object of the internal lottery, it is possible to win a small role that is the most basic character, so the basic composition of the character does not change. Therefore, even if these game states are included, the gameability can be easily understood without changing the basic role configuration.

  In the above embodiment, the execution mode of the continuous effect has been described on the premise that there is only one type, but it has a plurality of types of execution modes (for example, different modes that appear in the continuous effect). Also good. Different data is stored in the ROM 123 for each type of execution mode of the continuous effect, and the CPU 121 can read the data of the selected execution mode from the ROM 123 and execute the continuous effect. For example, the slot machine 1 may be provided with an effect execution mode selection button so that the player can select a desired continuous effect by operating this button.

  The execution mode of the continuous effect can be selected in advance by setting a dip switch (such as one that changes the allocation of the address space of the ROM 123) on the effect control board 102, for example. . In this case, a plurality of types of front panels can be applied, and a dip switch can be set in accordance with a full-surface panel applied to an individual machine to select a continuous performance execution mode. For example, in a machine to which a front panel on which character A is displayed is set, a dip switch is set so that a continuous production in which character A appears is performed, and on a machine to which a front panel in which character B is displayed is applied. The dip switch can be set so that a continuous production in which B appears is performed.

  The setting of the dip switch can be fixed in advance on the manufacturer side, and the execution mode of the continuous effect can be selected in advance. Here, as a method of fixing the setting of the dip switch, after switching the setting of the dip switch to the desired setting, the switch lever is not cut so that it cannot be operated, or the space of the movable part of the switch lever is crimped. It can also be prevented from moving. The dip switch can be sealed with a resin or a seal can be attached. Alternatively, not only the dip switch but also the entire or part of the effect control board 102 (including at least the dip switch) can be sealed with a resin or a seal can be attached.

  Furthermore, the setting of the dip switch can be changed at the amusement store without fixing the setting at the maker side, and the execution mode of the continuous effect can be changed. The execution mode of not only the continuous effects but also other types of effects (for example, effects when a winning occurs) may be changed by the operation of the selection button or the setting of the dip switch as described above.

  In the above embodiment, a regular bonus winning flag with a shift to a regular bonus or a big bonus, a big bonus (1) winning flag, a big bonus (2) winning flag, a big bonus (3) winning flag is generated. Otherwise, it was assumed that it was carried over after the next game. Similarly, the JACIN winning flag accompanying the shift to the regular bonus was deleted only for the game regardless of whether or not it was won. However, the JACIN winning flag can also be carried over after the next game until a winning occurs.

  Even when the gaming state is a small role game with a big bonus, a regular bonus lottery that has been a lottery target in a normal gaming state can also be performed. In this case, the winning probability of the regular bonus may be higher than the winning probability in the normal gaming state. In this case, when the regular bonus winning flag is set, the lottery of JACIN (whether or not the winning flag is carried over) can be prevented from being performed. On the other hand, when the JACIN winning flag is carried over, it is possible to prevent the regular bonus lottery from being performed.

  In this way, the JACIN winning flag is carried over after the next game if no winning occurs, or the regular bonus carried over after the next game if no winning occurs is also determined as a lottery role in the small role game. The player can be given more opportunities to move to the regular bonus, so that the player can fully teach the benefits of the big bonus.

  In the above embodiment, the determination value number storage area uses a 2-byte area to store the determination value number in each case. However, in a general slot machine, the number of determination values of a combination such as regular bonus, big bonus (1), big bonus (2), big bonus (3) is set to exceed 255 in any gaming situation. It is impossible. 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, the number of determination values acquired in accordance with the set value or the like is sequentially added to the random number value for internal lottery, but from the value of random number for internal lottery that acquired the acquired determination value number Subtraction may be performed sequentially, and the result of subtraction may be used as a new random value for internal lottery. When the number of determination values is subtracted from the random number value for internal lottery, the 15th and 14th bits of the random number for internal lottery are set to “0”, and the subtraction result overflows (here, the subtraction result is negative) It can be determined whether or not

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

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

  FIG. 16 is an explanatory diagram of a first modification of the process (step S101) until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. Also in the first modification, the random number extracted from the random number generation circuit 115 is stored in the 16-bit general-purpose register 111GR included in the CPU 111.

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

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

  FIG. 17 is an explanatory diagram of a second modification of the process (step S101) until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. Also in this example, the random number extracted from the random number generation circuit 115 is stored in the 16-bit general-purpose register 111GR included in the CPU 111.

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

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

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

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

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

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

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

  In 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, based on the current symbol position when the stop condition is satisfied and the setting status of the winning flag, pull-in control is performed so that the symbols of the winning symbol are aligned, or the winning symbol is not winning As an example, a slot machine that stops the rotation of the reels 3L, 3C, and 3R by a control method that performs removal control so that the symbols are not aligned has been described.

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

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

  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 variably displays a symbol on a display device such as a liquid crystal display device may be used instead of the variable display device 2 as described above.
