<P>PROBLEM TO BE SOLVED: To provide games by mainly using a variable display device for performance provided separately from a variable display device used for judging winning, and to improve performance effect by the variable display device for performance without causing distrust of a player. <P>SOLUTION: Virtual reels are displayed on a liquid crystal display more easily recognizable than the variable display device used for judging winning, and patterns for performance are fluctuated and displayed corresponding to fluctuation display of a pattern on the variable display device. Tokens are put out when a combination for small win is formed. When a big bonus prize is won, a game state transferred to a big bonus but the tokens are not put out. When a big bonus pattern is formed on the variable display device, a display mode of losing is formed by the virtual reels on the liquid crystal display. When the combination for small win is formed first time on the variable display device after the winning of the big bonus, a display mode of the big bonus is formed by the virtual reels regardless of whether the player wins the big bonus or not. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

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

  A slot machine generally includes a variable display device having a plurality of (usually three) reels having a plurality of types of symbols as identification information drawn on the outer periphery, and when all the reels stop rotating. When a combination of symbols stopped on the active line is in a predetermined display mode, a winning is generated. Each reel constituting the variable display device starts rotating when the player operates the start lever, and stops when the player operates a stop button provided corresponding to each reel.

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

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

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

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

  However, in order not to cause the player to feel distrust, it is not possible to derive a display mode unrelated to the progress of the game to the effect variable display device. Therefore, for example, when a bonus symbol is derived to the variable display device, the final display result in the effect variable display device is to completely correspond to the display result of the variable display device. It is also possible to produce an effect in the process. Even when a bonus symbol is not derived to the effect variable display device, there is a case where an effect due to the change of the symbol is performed. Such an effect makes the player expect a profit of the bonus.

  In this case, the time required to produce an effect in the process of changing the design of the effect variable display device is usually longer than the time required to stop the design in the variable display device. For this reason, if the player sees the variable display device and the bonus symbol is not derived when the effect is performed in the process of changing the symbol in the effect variable display device, the bonus is also given to the effect variable display device. It turns out that the symbol is not derived. Then, in the effect performed in the process of changing the design in the effect variable display device, the player cannot be expected to expect the bonus profit.

  The present invention realizes gameplay mainly based on a variable display device for production different from the variable display device used for winning determination, and also provides a production effect by the variable display device for production without causing the player to feel distrust. An object of the present invention is to provide a slot machine capable of increasing the number of times.

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,
An effect variable display device (liquid crystal display 4) that is provided separately from the variable display device, is provided more easily than the variable display device, and displays a plurality of types of effect identification information that can be distinguished from each other. (Virtual reel))
Allowed to derive a plurality of types of winning display results including special display results (big bonus (1), big bonus (2)) with a transition of the gaming state before the display results of the variable display device are derived Pre-determining means (steps S102 to S111) for determining whether to do by lottery,
Stop operation means (stop buttons 12L, 12C, 12R) for instructing to stop the variable display of the identification information on the variable display device by the player's operation;
Stop operation detection means (stop switches 42L, 42C, 42R) for detecting the operation of the stop operation means;
When the stop operation detection means detects an operation of the stop operation means, the display of the variable display device is derived by stopping the variation display of the identification information according to the determination result of the prior determination means. Derivation control means (steps S306, S310, S313);
When the special display result is derived as the display result of the variable display device, special game state control means for shifting the game state from the next game to a special game state (big bonus) different from the normal game state (step S402) , S404),
In the game from the determination that the derivation of the special display result is permitted by the prior determination means to the end of the special gaming state based on the determination, the special display result is displayed on the variable display device based on the determination. When the predetermined condition is satisfied regardless of whether or not the effect is derived, the effect variable display device derives the effect special display result (the display mode of the big bonus) corresponding to the special display result. And derivation control means (step S611, step S718).

  In the slot machine, when the gaming state is shifted to the special gaming state, the player can benefit from the special gaming state. Here, the transition of the gaming state to the special gaming state is triggered by the special display result being derived as the display result of the variable display device, but the special display for production as the display result of the variable display device for production The result is derived when a predetermined condition is established in the game after it has been decided to derive the special display result regardless of whether or not the special display result is actually derived.

  Thus, regardless of whether or not the special display result is derived to the variable display device, the effect special display result is derived to the effect variable display device. Therefore, before the display result of the effect variable display device is derived. Even if the special display result is not derived to the variable display device by looking at the variable display device, the effect special display result may be derived, and the player's expectation for the special gaming state is not lost. On the other hand, when the special display result for presentation is derived, it is determined that at least the derivation of the special display result is allowed, so that it is certain that the player can benefit from the special gaming state. For this reason, without causing the player to feel distrust, deriving the display result that does not correspond to the display result of the variable display device increases the effect of the effect by the variable display device for the effect, thereby improving the interest of the game. .

  The derivation control means always derives the special display result regardless of the operation procedure of the stop operation means when it is determined by the prior determination means that the derivation of the special display result is allowed. It may be a thing. In addition, the derivation control means is operated by the stop operation detecting means according to a predetermined procedure when the prior determination means determines that the derivation of the special display result is allowed. The special display result may be derived on the condition that the fact is detected. Here, the predetermined procedure is, for example, that the special display result can be derived even if the variation display of the identification information is stopped within a predetermined maximum delay time from the detection of the operation of the stop operation means. It can be a procedure.

  Further, the derivation control means controls so that the special display result is not derived for a game determined to allow the derivation of the special display result by the prior determination means or for a predetermined number of games from the game. Can be. For example, when the pre-determining means determines that the derivation of the special display result is permitted, it is also determined that the derivation of the re-game display result accompanied by the re-game is permitted. In this case, the re-game display If the result is derived with priority, the special display result is not derived in a game in which it is determined that the derivation of the special display result is allowed. Alternatively, the derivation control means may display a display result other than the special display result for a predetermined number of games from the game determined to permit the derivation of the special display result regardless of the determination result of the prior determination means. Can be derived.

  Further, the effect derivation control means can variably display the effect identification information in a special variation mode different from the normal variation mode in the process until the effect special display result is derived. In addition, the effect derivation control means may change the effect identification information in a special variation mode at a predetermined rate even after it is determined that the derivation of the special display result is permitted. Display results other than the special display result can be derived. In this case, on the condition that the predetermined condition is satisfied before it is determined that the derivation of the special display result is permitted, the effect identification information can be variably displayed in a special variation mode at a predetermined ratio. .

The slot machine is
In a game in which a small combination display result is derived to the variable display device as the winning display result, valuable value providing means for adding a predetermined number of valuable values corresponding to the derived small combination display result (step S412) , S414). In this case,
The effect derivation control means is based on the determination based on the determination in the game from the time when the prior determination means determines that the derivation of the special display result is permitted until the special gaming state based on the determination ends. Regardless of whether or not the special display result is derived to the variable display device, when the small combination display result is first derived (step S609 (YES) → S610 (YES)), the special display result for presentation Can be derived (step S611).

  In this way, the special display result for performance is derived in the first game from which the small role display result is derived, so that it is possible to effectively obtain the special gaming state in conjunction with the addition of the valuable value. Can be shown to the player.

  Here, when the derivation control means determines that the derivation of the small role display result is permitted by the prior determination means, the stop operation detection means is independent of the operation procedure of the stop operation means. The small combination display result may be derived.

  In this case, when it is determined that the derivation of the small role display result is permitted, the small role display result is derived. Therefore, the effect derivation control unit permits the derivation of the small role display result. Since it is possible to decide to derive the special display result for the effect when it is determined that the effect is determined, it is possible to easily control the change display stop of the identification information for the effect.

  When it is also determined that derivation of the small part display result is permitted in the game after the prior determination means determines that the derivation of the special display result is permitted, the derivation control means The small combination display result may be derived with priority over the special display result. In this case, when the small role display result is first derived in the game after it is determined that the derivation of the special display result is permitted, the special display result for presentation can be derived.

  On the other hand, when it is also determined that the derivation of the small part display result is permitted in the game after the prior determination means determines that the derivation of the special display result is permitted, the derivation control means The special display result may be derived with priority over the small combination display result. In this case, when the small role display result is first derived in the game after it is determined that the derivation of the special display result is permitted, or when the special display result is derived, the special display for production is performed. The result can be derived.

  In this case, if the display result derived to the variable display device when it is determined that the derivation of the small role display result is allowed is the small role display result, the special gaming state profit is linked with the addition of the valuable value. Can be effectively shown to the player. If the display result derived to the variable display device when it is determined that the derivation of the small role display result is permitted is the special display result, the special game state is transferred to the special game state. It is possible to show the player that the profit of the gaming state can be obtained.

The slot machine is
When it is determined by the pre-determining means that derivation of the special display result is permitted, a continuous effect indicating the possibility that the derivation of the special display result is determined is longer than one game. Further, it may further include continuous effect execution means (steps S712 and S721) that are continuously executed during the continuous effect period that ends until the special gaming state based on the determination ends. In this case,
The effect derivation control means derives the special display result to the variable display device based on the determination in a game in which the continuous effect executed based on the determination to permit the derivation of the special display result is completed. Regardless of whether or not the display result is derived to the variable display device (step S716 (YES) → S717 (YES)), the special display result for presentation can be derived ( Step S718).

  By showing the special display result for the effect in the game in which the continuous effect ends in this way, it is possible to effectively show the player that the special game state can be gained in conjunction with the execution of the continuous effect. Can do.

The continuous effect execution means includes continuous effect determination means for determining whether or not to execute the continuous effect when it is not determined by the prior determination means that the derivation of the special display result is allowed. Even when the continuous effect determining means determines to execute the continuous effect, the continuous effect may be continuously executed for a continuous effect period longer than one game. In this case,
When the display result is derived to the variable display device in the game in which the continuous effect executed based on the determination of the continuous effect determining unit is terminated, the effect derivation control unit displays a display other than the effect special display result. The result can be derived to the effect variable display device.

In the above slot machine,
The effect derivation control means determines when the display result of the variable display device is derived in the game for which the derivation of the special display result is permitted or when the derivation of the special display result is permitted. When a display result of the variable display device is derived in a game after a predetermined number of games (however, the number of games in which the special gaming state based on the determination does not end) is determined from the played games, It is also possible to derive a special display result for performance.

  In this case, when it is determined that it is determined that the derivation of the special display result is permitted, or when it is determined that the derivation of the special display result is permitted, it is determined that the predetermined number of games has elapsed. At this point, since it is possible to decide to derive the special display result for production, it becomes possible to easily control the stop of the variable display of the identification information for production.

The slot machine is
It is further provided with special signal output means (external output board 105) for outputting a special signal to an external device connected to the slot machine from when the predetermined condition is satisfied until the special gaming state is ended. Also good.

  When the special signal is output to the external device, it is possible to perform an effect according to the special game state by the effect device outside the slot machine. Here, the output of the special signal to the external device is started not when the gaming state is shifted to the special gaming state but when the predetermined condition is satisfied. Therefore, even before the special display result is derived as the display result of the variable display device and the gaming state is shifted to the special gaming state, the special display result for effect is derived as the display result of the variable display device for effect. In accordance with this, an effect according to the special game state can be performed by an external effect device.

  The special signal output means outputs the special signal between the time when the predetermined condition is satisfied and the time when the special gaming state ends, and from the time when the special display result is derived. A second special signal different from the special signal may be further output to the external device. Even if the second special signal is output between the time when the special display result is derived and the predetermined condition is satisfied, the special gaming state is terminated after the special display result is derived. It may be output until it is done.

  In this case, even if the output of the special signal is started when the predetermined condition is satisfied, the external device is informed that the gaming state is controlled to the special gaming state by the second special signal. Accurate information can be collected.

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

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

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

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

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

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

Further, in this case, the slot machine is
Stop operation means (stop buttons 12L, 12C, 12R) for instructing to stop the variable display of the identification information on the variable display device by the player's operation;
Stop operation detection means (stop switches 42L, 42C, 42R) for detecting the operation of the stop operation means can be provided. here,
The derivation control means displays the variation of the identification information within a predetermined maximum delay time (190 milliseconds (4 frames)) when the stop operation detection means detects an operation of the stop operation means. Can be stopped,
The variable stop control means is a specific small combination display having the highest probability of being determined to be allowed to be derived by the pre-determining means among the small combination display results in the game controlled in the special special game state. Regardless of the timing at which the stop operation detecting means detects the operation of the stop operation means when it is determined that the derivation of the result (bell) has been determined, the identification within the range of the predetermined maximum delay time It is preferable to derive a small combination display result (FIGS. 2 and 3).

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

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

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

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

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

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

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

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

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

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

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

The slot machine 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 S106, S107). Here, the slot machine is
A pulse generation circuit (pulse generation circuit 115a) for generating a pulse signal of a predetermined frequency;
An n-bit (n is an integer greater than or equal to 2) array data signal is inverted alternately between the first level and the second level every time a pulse signal is input from the pulse generation circuit, and Each time the level of the (m-1) th bit (m is an integer of 2 or more: m ≦ n) from the lower level is inverted from the first level to the second level, the level of the mth bit from the lower level is changed to the first level. A counter circuit (lower counter 115b, upper counter 115c) that alternately inverts and outputs at two levels;
When a predetermined extraction condition resulting from the player's operation is satisfied, the n-bit array data signal output from the counter circuit is latched, and the bit order of the latched n-bit array data signal is changed. 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.

When a predetermined extraction condition resulting from the player's operation is satisfied, the order of bit arrangement is not changed for each of the upper n bits and the lower n bits of the data signal output from the counter circuit, and The upper n bits of the data signal output from the counter circuit are set to upper numerical data which is the upper n bits of the 2n-bit numerical data, and the lower n bits of the data signal output from the counter circuit are set to the 2n Numeric data fetching means (FIGS. 21A to 21D) for fetching the 2n-bit numeric data as lower numeric data that is the lower n bits of the bit numeric data;
The lower numeric data and the upper numeric data fetched by the numeric data fetching means are arranged in different orders, and the upper numeric data and the lower numeric data are interchanged with each other so that the specific lower numeric data and the specific upper numeric data are respectively exchanged. As a data conversion means (FIG. 21 (e)) for storing in the specific upper area and the specific lower area provided in the storage means provided in the game control means,
Determining that the game control means includes numerical data obtained by performing a predetermined operation on the numerical data stored in the specific upper area and setting the numerical data obtained as a result of the predetermined operation as upper n bits. Numerical data input means (FIGS. 19 (e), (f), (g), (h), (j)) for inputting into the region may be further provided.

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

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

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

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

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

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

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

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

The I / O port 114 inputs and outputs control signals to and from each circuit connected to the game control board 101.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

  In the slot machine 1, a winning is awarded when the symbols are arranged on any of the active lines of the variable display device 2. The types of winning combinations are determined according to the gaming status, but can be broadly divided into special roles that involve the transition of gaming status, small roles that involve the payout of medals, and no need to set the number of bets. There is a re-player who can start the next game. In order to win each winning combination determined according to the gaming state, it is necessary to win an internal lottery to be described later and to set a winning flag for the winning combination in the RAM 112.

  FIG. 5A is a diagram showing a winning combination table by gaming state. The winning combination table according to gaming state is stored in advance in the ROM 113 and is used to determine the winning combination determined in the internal lottery. The registered content of the winning combination table according to gaming state depends on the gaming state. It shows the role that has been determined. As a combination in the slot machine 1, a regular bonus, a big bonus (1), a big bonus (2), JACIN as a special combination, a bell and cherry as a small combination, and a replay as a re-playing combination are defined.

  In the regular bonus game state, bells and cherries, which are small roles, are determined as winning combinations, and are subject to lottery in the internal lottery in the regular bonus. In the big bonus game state, JACIN, which is a special combination, and Bell and Cherry, which are small combinations, are determined as winning combinations, and are subject to lottery in an internal lottery in the big bonus. In the normal gaming state, regular bonuses that are special roles, big bonus (1) and big bonus (2), bells and cherries that are small roles, and replays that are re-playing roles are defined as winning roles, A lottery is performed in an internal lottery in a normal gaming state.

  The regular bonus is awarded when a combination of “red 7-white 7-blue 7” is arranged on any of the active lines (eight) 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 (1) is won when a combination of “red 7-white 7-white 7” is arranged in any of the active lines (eight) in the normal gaming state. The big bonus (2) is won when a combination of “red 7-blue 7-blue 7” is arranged on any of the active lines (eight) in the normal gaming state. When the big bonus (1) or big bonus (2) is won, the gaming state shifts to a big bonus (1) and a big bonus (2) (collectively referred to as a big bonus). In the big bonus, a game called a small role game can be played.

  While the gaming state is the big bonus, the big bonus medium flag is set in the RAM 112. When winning the big bonus (1) or big bonus (2), the big bonus winning flag is also set in the RAM 112 until the display result is derived in the first game of the next big bonus. When the next game starts, the big bonus winning flag is erased and the big bonus starting flag is set in the RAM 112. A weight is applied after the result of the first game of the big bonus is derived based on the big bonus start flag. After completing the wait, the big bonus start flag is erased.

  JACIN is awarded when a combination of “Bell-Cherry-Cherry” is placed on any of the active lines (eight) in the small role game in the big bonus, but in a game state other than the small role game, Even if the combination is complete, JACIN won't win. When winning JACIN, the above-mentioned regular bonus is provided in the big bonus, and the regular bonus medium flag is also set in the RAM 112 in addition to the big bonus medium flag.

  The big bonus (1) and the big bonus (2) have the same game characteristics, but there is a difference in the upper limit of the number of medals that the player can acquire. More specifically, the upper limit of the number of medals earned in the big bonus (1) is 180, and the big bonus (1) when the total number of payouts exceeds 165 which is obtained by subtracting 15 which is the maximum payout number at the time of winning. Ends. The upper limit of the number of medals earned in the big bonus (2) is 360, and the big bonus (2) ends when the total number of payouts exceeds 345, which is obtained by subtracting 15 which is the maximum payout number at the time of winning. When the regular bonus in the big bonus reaches 165 or 345, the regular bonus is terminated together with the big bonus.

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

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

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

  Reference of the combination according to the gaming state is performed according to the winning combination table according to gaming state shown in FIG. That is, when the gaming state is a regular bonus (including the case where it is provided during the big bonus), the bell and cherry are sequentially read out as the internal lottery target roles, and the gaming state is in the small role game during the big bonus. Sometimes, JACIN, bell, and cherry are sequentially read out as the target combination for internal lottery. When in the normal gaming state, the regular bonus, big bonus (1), big bonus (2), bell, cherry, and replay are sequentially read out as the subject combination of the internal lottery.

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

  The number of determination values for each combination is registered corresponding to the number of bets (BET) set by the player in the game. This is because even with the same combination, the winning probability in the regular bonus may 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”).

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

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

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

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

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

  The addresses ADD + 12, ADD + 14, ADD + 16, ADD + 18, ADD + 20, and ADD + 22 are addresses that are referred to when the internal lottery target is the big bonus (1) and the set value is 1-6. The addresses ADD + 24, ADD + 26, ADD + 28, ADD + 30, ADD + 32, and ADD + 34 are addresses that are referred to when the internal lottery target role is the big bonus (2) and the set value is 1 to 6, respectively. With regard to the big bonuses (1) and (2), the number of determination values is individually stored according to the set value, and a different number of determination values is stored, so that the big bonus (1), ( The winning probabilities in 2) will be different.

  Further, the address ADD + 36 is an address that is referred to regardless of the set value when the target combination of the internal lottery is JACIN, and 4311 is acquired as the number of determination values regardless of the set value.

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

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

  The address ADD + 62 is an address that is referred to regardless of the set value when the bet number is 1, that is, when the target character of the internal lottery is cherry in the regular bonus. The address ADD + 64 is an address that is referred to regardless of the set value when the number of bets is 3, that is, in the normal gaming state or in the small role game, when the target combination of the internal lottery is cherry. The number of determination values for cherry is registered according to the number of bets, but since the same value is registered, the winning probability of cherry is the same in any gaming state. The address ADD + 66 is an address that is referred to when the target part of the internal lottery is replay and the betting number is 1 to 6 in the normal gaming state.

  FIGS. 7A to 7C are diagrams illustrating an example of the relationship between the value of the random number for internal lottery and the number of determination values of each combination and the winning combination. FIG. 7A shows an example in a normal gaming state, FIG. 7B shows an example in a small role game, and FIG. 7C shows an example in a regular bonus. FIGS. 7A to 7C show examples in which the set value is 6, and in FIG. 7A, both the regular bonus winning flag and the big bonus winning flag are set. An example is shown when there is not. In the figure, examples other than this are omitted, but similarly, the relationship between the value of the random number for internal lottery and the number of judgment values of each combination and the winning combination will be determined.

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

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

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

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

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

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

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

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

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

  Similarly, when the level of the (m−1) th bit data signal is inverted from the H level to the L level, that is, whenever the logic value of the (m−1) th bit data signal changes from 1 to 0, the mth bit data The signal level is alternately inverted between the H level and the L level. 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. 8B is an explanatory diagram until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. The random number extracted from the random number generation circuit 115 is stored in a 16-bit general-purpose register 111GR included in the CPU 111.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

  Next, output of an external output signal from the external output board 105 will be described. The CPU 111 of the game control board 101 performs an external output signal generation process in parallel with the game progress process (FIG. 9 to be described later), and outputs the external output signal from the external output board 105 to the external device. Among the external output signals, the regular bonus medium signal and the big bonus medium signal are output when the regular bonus medium signal and the big bonus medium signal are set in the RAM 112, respectively.

  However, the period during which the big bonus medium signal is output to the external device does not coincide with the period during which the gaming state is controlled by the big bonus. The big bonus medium signal is displayed when the big bonus (1) winning flag or the big bonus (2) winning flag is set and the first small bonus is won (the small bonus winning and the big bonus (1) or big bonus (2) The output is started at any time (regardless of which winning is first), and the output is stopped when the gaming state of the big bonus ends.

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

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

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

  The virtual reels, for example, “7”, “Cherry”, “Watermelon”, “Bell”, “Replay” arranged in a predetermined arrangement correspond to the reels 3L, 3C, 3R of the variable display device 2. Three will be displayed. "7" and "Cherry" or "7" and "Bell" are double tempers (when two virtual reels are stopped, it is finally possible to align both symbols on the active line. The arrangement can be made to be an embodiment). The virtual reels start to change when the reels 3L, 3C, and 3R start to rotate, and stop changing when the reels 3L, 3C, and 3R stop rotating. However, the stop of the virtual reel is not limited by the maximum stop delay time of 190 milliseconds like the reels 3L, 3C, and 3R of the variable display device 2.

  The first time you win the bell or cherry in the game after the big bonus (1) winning flag or big bonus (2) winning flag is set (before the big bonus (1) or big bonus (2) wins) Whether or not it is later), a display mode (a display mode of a big bonus) in which the symbol “7” is always aligned is derived. Here, when the bell or cherry is won before the big bonus (1) or the big bonus (2) is won, the big bonus (1) or the big bonus (2) depending on the operation timing of the stop buttons 12L, 12C, 12R. If you don't win the big bonus (2) or big bonus (2), you must win the bell or cherry.

  Also, in the game after the Big Bonus (1) Winning Flag or Big Bonus (2) Winning Flag is set, win the Big Bonus (1) or Big Bonus (2) before winning the first bell or cherry When this is done, the display mode of the loss is derived on the virtual reel. In this case, the display mode of the big bonus is derived on the virtual reel in the game that is first won by the bell or cherry after the gaming state is controlled to the big bonus by winning the big bonus (1) or the big bonus (2). .

  That is, the display mode of the big bonus is derived only when winning a bell or cherry or winning a big bonus (1) or big bonus (2). The display mode of the big bonus is the same whether the big bonus (1) is won (does) or the big bonus (2) is won (does).

  When the bell or cherry is won except when the display mode of the big bonus is derived (the bell or cherry is always derived to the variable display device 2), the symbols “bell” and “cherry” are displayed as the virtual reel display mode. Are aligned and stopped. When the replay is won (the replay is always derived to the variable display device 2), the “replay” symbols are arranged and stopped as the virtual reel display mode. In the regular bonus, JACIN, the display mode of losing is derived as the display mode of the virtual reel.

  Note that when the display mode of the big bonus is finally derived on the virtual reel of the liquid crystal display 4, the variation display mode up to the derivation is changed to the normal variation mode (a predetermined constant speed in the forward direction). (Variation) can be a special aspect (for example, low-speed or high-speed fluctuation, reverse fluctuation, or a combination thereof). In addition, even after the big bonus display mode is derived on the virtual reel and before the next big bonus (1) or big bonus (2) is won, when the bell or cherry is won, the virtual bonus is displayed at a predetermined rate. It is possible to change the reel design in a special manner and align the “bell” or “cherry” design to stop the virtual reel.

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

  FIG. 9 is a flowchart showing processing for one game executed by the CPU 111 of the game control board 101. This process is also executed after the power is turned on and a predetermined boot process is performed, or immediately after the setting is changed by operating the setting switch 91. When the process of one game is started, first, an initial process including a process of clearing a predetermined area of the RAM 112 is performed (step S1).

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

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

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

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

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

  When the winning determination process ends, a payout process is performed (step S7). In the payout process, the credit is increased by the number of payouts set in the winning determination process. However, when the number of credits accumulated as data reaches 50, the hopper motor 82 is driven to pay out an excess number of medals from the medal payout slot 71. 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). Details of the payout process will be described later. Then, the process for one game ends, and the process for the next one game starts.

  Next, the lottery process in step S3 will be described in detail. FIG. 10 is a flowchart showing in detail the lottery process executed by the CPU 111 in step S3. In the lottery process, when a small role is won in the previous game, the payout display unit 21 lights up the scheduled payout number, so the payout display 51 is controlled to turn it off. If there is no lighting display of the number of payouts, the light-off state is only maintained (step S101).

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

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

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

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

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

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

  Next, the random number acquisition process in step S102 will be described in detail. FIG. 11 is a flowchart showing in detail the random number acquisition process executed by the CPU 111 in step S102. In the random number acquisition process, first, interrupt to the CPU 111 is prohibited (step S201). Next, a sampling command is output to the sampling circuit 116, the random number generated by the random number generation circuit 115 is latched, and the value of the latched random number is input from the I / O port 114 and extracted. The random number value extracted from the random number generation circuit 115 is stored in the general-purpose register 111GR (step S202).

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

  Next, the reel fluctuation stop process in step S5 will be described in detail. FIG. 12 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 of the big bonus (1) (red 7-white 7-white 7) is derived on any active line (step S401). If the display mode of the big bonus (1) is derived, the big bonus medium flag is set in the RAM 112 and the big bonus winning flag set in the RAM 112 is erased. Also, the big bonus end number is set to 165 and stored in a predetermined area of the RAM 112. Further, the HIT lamp 54 is turned on (step S402). Then, the process proceeds to step S417.

  When the display mode of the big bonus (1) is not derived, it is determined whether or not the display mode of the big bonus (2) (red 7-blue 7-blue 7) is derived on any active line. (Step S403). If the display mode of the big bonus (2) is derived, the big bonus medium flag is set in the RAM 112 and the big bonus winning flag set in the RAM 112 is erased. Also, the big bonus end number is set to 345 and stored in a predetermined area of the RAM 112. Further, the HIT lamp 54 is turned on (step S404). Then, the process proceeds to step S417.

  If the display mode of the big bonus (2) is not derived, it is determined whether or not the display mode of the regular bonus (red 7-white 7-blue 7) is derived on any active line (step S405). ). If the display mode of the regular bonus has been derived, the regular bonus flag is set in the RAM 112 and the regular bonus winning flag set in the RAM 112 is erased. Further, the HIT lamp 54 is turned on and a regular bonus medium signal is started to be output from the external output board 105 (step S406). Then, the process proceeds to step S417.

  If the display mode of the regular bonus is not derived, it is determined whether or not the JACIN display mode (bell-cherry-cherry) is derived on any active line (step S407). If the display mode of JACIN is derived, a regular bonus medium flag is set in the RAM 112. In this case, a regular bonus medium flag is also set on top of the big bonus medium flag. In addition, a regular bonus message is started to be output from the external output board 105 (step S408). Then, the process proceeds to step S417.

  If the JACIN display mode is not derived, it is determined whether or not the replay display mode (red 7-JAC-cherry) is derived on any active line (step S409). If the replay display mode has been derived, a replay flag is set in the RAM 112 (step S410). This replay flag is deleted when the bet number is automatically set in the next game. Then, the process proceeds to step S417.

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

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

  In step S415, it is determined whether the big bonus medium flag is set in the RAM 112, or whether the big bonus (1) winning flag or the big bonus (2) winning flag is set. If none of the big bonus medium flag, the big bonus (1) winning flag, and the big bonus (2) winning flag are set, the process proceeds to step S417 as it is. If the big bonus medium flag is set in the RAM 112, or if the big bonus (1) winning flag or the big bonus (2) winning flag is set, output of the big bonus medium signal is started from the external output board 105. However, if the big bonus medium signal has already been output, the output state is only maintained (step S416). Then, the process proceeds to step S417.

  In step S417, a winning information command indicating the winning combination is generated and transmitted to the effect control board 102 if there is a winning or not and if there is a winning. Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  Next, the payout process in step S7 will be described in detail. FIG. 14 is a flowchart showing in detail the payout process executed by the CPU 111 in step S7. First, the number corresponding to the winning combination is determined by controlling the hopper 80 and discharging the medals one by one while subtracting the planned payout number by 1 until the planned payout number set in the RAM 112 becomes 0. Pay out the medal to the player. However, if the number of credits has not reached 50, the number of credits is incremented by 1 instead of discharging medals one by one (step S501).

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

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

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

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

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

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

  Further, if a small role winning flag, a replay winning flag, and a JACIN winning flag are set in the RAM 112, these are deleted. The regular bonus winning flag, the big bonus (1) winning flag, and the big bonus (2) winning flag are not deleted from the RAM 112 unless they have won the corresponding role in the game, and are carried over to the next game (step S514). . Further, here, the operation of the single BET button 14 and the MAX BET button 15 is also effective. Then, the payout process is terminated, and the process returns to the flowchart of FIG. When returning to the flowchart of FIG. 9, the processing for one game is finished as it is.

  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, display of virtual reels on the liquid crystal display 4) will be described.

  FIG. 15 is a flowchart showing processing executed by the CPU 121 of the effect control board 102. On the side of the effect control board 102, it is determined whether or not a command sent from the game control board 101 has been received (step S601). Until any command is received, the process of step S601 is repeated. When any command is received from the game control board 101, it is determined what kind of the received command is (step S602).

  If the type of the received command is the winning status notification command transmitted in step S112, the symbol display mode in the variable display device 2 stored in the RAM 122 based on the reel stop command received in the previous game is shown. Information is cleared (step S603). Further, the setting status of the winning flag indicated by the received winning status notification command is stored in a predetermined area of the RAM 122 (step S604).

  Next, the two winning status notification commands are compared to determine whether or not a new big bonus (1) or big bonus (2) has been won in the current game (step S605). When a big bonus (1) or a big bonus (2) is newly won in this game, a big bonus flag is set in the RAM 122 (step S606). Then, the process proceeds to step S607. If a new big bonus (1) or big bonus (2) has not been won in this game, the process proceeds to step S607. In step S607, the virtual reel is displayed on the liquid crystal display 4, and the symbol variation display by the virtual reel is started. Then, the process returns to step S601.

  When the type of the received command is the reel stop command transmitted in step S306, S310 or S314, information indicating the symbol derived to the reels 3L, 3C, 3R indicated by the reel stop command is stored in the RAM 122 in advance. (Step S608).

  Next, it is determined whether or not the big bonus flag is set in the RAM 122 (step S609). Here, the case where the big bonus flag is set indicates whether the big bonus (1) or the big bonus (2) has already been won after winning the big bonus (1) or the big bonus (2). Regardless, this is the case where you have not yet won the Bell or Cherry small role.

  If the big bonus flag is not set, the process proceeds to step S614. If the big bonus flag has been set, it is determined whether or not the winning combination of the bell or cherry is won in the current game based on the winning situation stored in the RAM 122 in step S604 (step S610). If the winning combination of bell or cherry is not won, the process proceeds to step S614.

  If you win the bell or cherry small role, you will always win the big bonus (1) or big bonus (2), or the bell or cherry small role. In this case, one of the three virtual reels is stopped in accordance with the stopped reels 3L, 3C, 3R, and a big bonus common to the big bonus (1) and the big bonus (2) is stopped here. The display mode (7-7-7) is derived (step S611).

  Next, it is determined whether all of the reels 3L, 3C, 3R have been stopped based on the information indicating the stop state stored in the RAM 122 (step S612). If any of the reels 3L, 3C, 3R is not stopped, the process directly returns to step S601. When all of the reels 3L, 3C, 3R are stopped, the big bonus flag in the RAM 122 is erased (step S613). Then, the process returns to step S601.

  In step S614, the information indicating the setting status of the winning flag stored in the RAM 122 and the information indicating the stop status of the reels 3L, 3C, and 3R are referred to, and among the three, the reels 3L, 3C, and 3R are stopped. One of the virtual reels is stopped, and a symbol corresponding to the symbol derived to the variable display device 2 is derived to the virtual reel. However, the display mode of the winning is derived to the virtual reel only when winning the bell, cherry or replay. Even if winning the regular bonus, big bonus (1), big bonus (2) or JACIN, The virtual reel is caused to derive the same display mode as in the case of losing. Then, the process returns to step S601.

  If the received command type is another command, processing corresponding to the type of each command (the details are omitted because it is not related to the present invention) is executed (step S615). Thereafter, the process returns to step S601.

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

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

  Also, the winning display mode is derived on the virtual reel of the liquid crystal display 4 only when the bell, cherry or replay is won, and even if the big bonus (1) or big bonus (2) is won. Only the display mode of losing is derived to the virtual reel. In the big bonus (1) or big bonus (2), there is no payout of medals. Therefore, when the player plays the game by looking only at the virtual reel of the liquid crystal display 4, the game state is changed at any timing. It is possible to prevent the player from perceiving whether the game is controlled by the big bonus.

  Here, the virtual bonus of the liquid crystal display 4 is derived from the display mode of the big bonus when the small bonus is first won after winning the big bonus (1) or the big bonus (2). For this reason, when the player is viewing the variable display device 2 when a change is likely to derive the display mode of the big bonus on the virtual reel, the big bonus (1) or the big bonus (2) is not derived. However, if the bell or cherry is derived, the display mode of the big bonus may still be derived, so that the player's expectation for the big bonus is not lost.

  Also, if you win the Big Bonus (1) or Big Bonus (2) and win the Big Bonus (1) or Big Bonus (2) when you first win a small role, the gaming state will actually shift to the Big Bonus As it is done, you will be able to show the player that you will get a big bonus. On the other hand, even if the Big Bonus (1) or Big Bonus (2) is not won, if the Big Bonus display mode is derived with the first small role winning as an opportunity, the Big Bonus is linked with the payout of medals. Can be effectively shown to the player.

  When the display mode of the big bonus is derived on the virtual reel of the liquid crystal display 4, the gaming state may not yet be controlled to the big bonus. For this reason, a replay prize may be awarded after the display mode of the big bonus is derived on the virtual reel. However, when the display mode of the big bonus is derived on the virtual reel, at least the big bonus (1) or the big bonus (2) which is the premise thereof is won, so that the player may feel distrust. Absent.

  The winning combination of the small role that triggers the virtual reel to derive the display mode of the big bonus is the stop button 12L, 12C, 12R as long as it is won as a result of the internal lottery regardless of whether it is a bell or a cherry. It can always be derived regardless of the operation timing. On the other hand, the big bonus (1) or the big bonus (2) may not be derived depending on the operation timing of the stop buttons 12L, 12C, and 12R even if the internal winning is made. In this way, it is assumed that the big bonus is missed, but it can be said that not only the slot machine 1 according to this embodiment but also the conventional slot machine is assumed to have a small role that is not missed. That is.

  Here, when the big bonus is won according to the display result of the variable display device as in the prior art, the variable display device 2 may be configured so that the display pattern of the effect symbols is the big bonus as in the virtual reel of this embodiment. Unless the symbols to be stopped for each of the reels are determined, it is not possible to determine what symbol should be derived as a design for presentation.

  On the other hand, in the slot machine of this embodiment, the big bonus is applied to the virtual reel of the liquid crystal display 4 when it is determined that the bell or cherry is won after winning the big bonus (1) or the big bonus (2). It is possible to determine that the display mode should be derived. For this reason, since it is not necessary to determine the symbol to be derived to the virtual reel every time the reels 3L, 3C, 3R of the variable display device 2 are stopped, the control of the derivation of the symbol to the virtual reel can be easily performed. .

  Even if the display mode of the big bonus is not derived, that is, other than the case of winning the first small role after winning the big bonus (1) or the big bonus (2), the big bonus (1 As for the big bonus (2) and the regular bonus, even if it is derived as the display result of the variable display device 2, the display mode of the losing may be derived in the virtual reel. Only the bells, cherries, and replays that are not missed are derived to the virtual reel as the display mode according to the type of winning, so when the winning situation is judged, the symbols to be derived to the virtual reel can be decided and variable Since it is not necessary to determine the symbol to be derived to the virtual reel every time the reels 3L, 3C, 3R of the display device 2 are stopped, the control of the symbol derivation to the virtual reel can be easily performed.

  In addition, there are two types of payout medals, which are conditions for ending the big bonus, 165 and 345. The big bonus (1) or the big bonus (2) It will be determined by whether it is. Which of the big bonus (1) and the big bonus (2) wins is determined at the time of the internal lottery. For this reason, it is not necessary to re-execute processing for determining the number of payout medals as a condition for ending the big bonus, and the processing load can be reduced.

  In addition, even when the big bonus (1) is won and the big bonus is controlled, or the big bonus (2) is won and the big bonus is controlled, the big bonus derived to the virtual reel of the liquid crystal display 4 Are displayed in the same manner. For this reason, from the display result derived on the virtual reel of the liquid crystal display 4, it is not perceived by the player whether it is a big bonus that ends over 165 sheets or a big bonus that ends over 345 sheets. Can be.

  When the big bonus (1) or the big bonus (2) is won, the medal is not paid out and the payout display unit 21 is not displayed, so the player is not aware of the win. For this reason, the display result of the variable display device 2 is a big bonus that ends after exceeding 165 without making the Big Bonus (1) or Big Bonus (2) winning as much as possible, or exceeds 345. It is possible to prevent the player from perceiving as much as possible the big bonus that ends.

  By the way, when the big bonus (1) or the big bonus (2) is won, a big bonus medium flag is set in the RAM 112, and the gaming state is controlled to the big bonus. Here, when a big bonus medium signal is output from the external output board 105, if there is an effect by an effect device outside the slot machine 1 such as lighting of a lamp on the game island by the externally output big bonus medium signal, The player will know that he is in a big bonus.

  However, the big bonus medium signal is when the first small role is won after winning the big bonus (1) or big bonus (2) regardless of whether the big bonus (1) or big bonus (2) is won. That is, the output is started when the display mode of the big bonus is derived on the virtual reel. For this reason, even if an effect is provided by an effect device outside the slot machine 1 based on the big bonus medium signal output from the external output board 105, the display mode of the big bonus on the virtual reel is derived. In addition, it is possible to indicate that the gaming state is in the big bonus (in some cases, it is not yet a big bonus in practice) by the production by the external production device.

  When the big bonus (1) or the big bonus (2) is won without winning the small role after the big bonus (1) or the big bonus (2) is won, the display mode of the big bonus is derived on the virtual reel. Although the output of the big bonus medium signal is delayed as compared with the above, no medal is paid out when winning the big bonus (1) or the big bonus (2). However, in such a case, the output of the big bonus medium signal is the time when the small role is won first after the gaming state is controlled to the big bonus, and in response to receiving the medal payout first in the big bonus, An effect by an external effect device can be effectively started.

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

  The big bonus ends when the number of medals paid out exceeds 165 or 345 regardless of the number of digest games. Here, in a game with a big bonus (including a small role game and a regular bonus), since replay is not defined as a target character for internal lottery, no replay is won. Replay does not reduce the number of medals held by the player, but does not accompany the payout of medals, and therefore does not affect the number of payout medals, which is a condition for terminating the big bonus. In other words, even if you make a replay win during the big bonus, it will only increase the number of big bonus games unnecessarily, so by not defining the replay as a target for internal lottery in the big bonus, The game can be efficiently advanced without unnecessarily prolonging the state.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

  In the above embodiment, when the small bonus is first won after winning the big bonus (1) or the big bonus (2), the display mode of the big bonus is derived to the virtual reel of the liquid crystal display 4. . However, the opportunity to derive the display mode of the big bonus to the virtual reel after winning the big bonus (1) or the big bonus (2) is not limited to the first small role winning.

  For example, when a big bonus (1) or a big bonus (2) is won, a continuous effect over a plurality of games is performed, and a display mode of the big bonus is derived to a virtual reel in a game where the continuous effect ends. Can do. FIG. 16 is a flowchart showing processing executed by the CPU 121 of the effect control board 102 in this modification.

  The control on the game control board 101 side in this modification is the same as in the above embodiment. On the side of the effect control board 102, it is determined whether or not a command sent from the game control board 101 has been received (step S701). Until any command is received, the process of step S701 is repeated. When any command is received from the game control board 101, it is determined what kind of the received command is (step S702).

  If the type of the received command is the winning status notification command transmitted in step S112, the symbol display mode in the variable display device 2 stored in the RAM 122 based on the reel stop command received in the previous game is shown. Information is cleared (step S703). Further, the setting status of the winning flag indicated by the received winning status notification command is stored in a predetermined area of the RAM 122 (step S704). Further, the virtual reel is displayed on the liquid crystal display 4, and the symbol variation display by the virtual reel is started (step S705).

  Next, it is determined whether or not the value of the continuous effect counter provided in the RAM 122 is 0, that is, whether or not the continuous effect is not being executed (step S706). If the value of the continuous effect counter is not 0, the process proceeds to step S712 as it is. If the value of the continuous effect counter is 0, the two winning status notification commands are compared to determine whether or not a new big bonus (1) or big bonus (2) has been won in this game (step) S707). If a big bonus (1) or a big bonus (2) is newly won in this game, the process proceeds to step S711.

  If the big bonus (1) or big bonus (2) is not newly won in the current game, it is determined whether or not the gaming state in the current game is a big bonus or a regular bonus (step S708). . If the game state in the current game is a big bonus or a regular bonus, the process directly returns to step S701.

  If the game state in the current game is neither a big bonus nor a regular bonus, a continuous effect lottery for determining whether or not to start a continuous effect is performed based on the random number value extracted by the software random number function (step S709). Then, it is determined whether or not the continuous effect lottery is won (step S710). If the lottery is lost in the continuous effect lottery, the process returns to step S701. If the continuous effect lottery is won, the process proceeds to step S711.

  In step S711, 3 is set as an initial value in the continuous effect counter of the RAM 122. Then, the process proceeds to step S712. In step S712, an effect image corresponding to the value of the continuous effect counter is displayed on the liquid crystal display 4 together with the virtual reel, and an effect for the current game in the continuous effect is started. Then, the process returns to step S701.

  When the type of the received command is the reel stop command transmitted in step S306, S310 or S314, information indicating the symbol derived to the reels 3L, 3C, 3R indicated by the reel stop command is stored in the RAM 122 in advance. (Step S713).

  Next, it is determined whether or not the value of the continuous effect counter in the RAM 122 is 0 (step S714). If the value of the continuous effect counter is 0, the information indicating the setting status of the winning flag stored in the RAM 122 and the information indicating the stop status of the reels 3L, 3C, 3R are referred to, and the stopped reels 3L, 3C, In accordance with 3R, one of the three virtual reels is stopped, and a symbol corresponding to the symbol derived to the variable display device 2 is derived to the virtual reel. However, the display mode of the winning is derived to the virtual reel only when winning the bell, cherry or replay. Even if winning the regular bonus, big bonus (1), big bonus (2) or JACIN, The virtual reel is caused to derive the same display mode as in the case of losing (step S715). Then, the process returns to step S701.

  If the value of the continuous effect counter is not 0, it is further determined whether or not the value of the continuous effect counter is 1 (step S716). If the value of the continuous effect counter is 1, it is determined whether the big bonus (1) or the big bonus (2) is won based on the information indicating the setting status of the winning flag stored in the RAM 122 (step S717). If the big bonus (1) or the big bonus (2) is won, one of the three virtual reels is stopped in accordance with the stopped reels 3L, 3C, 3R, and the big bonus (1 ) And a big bonus (2) are derived (7-7-7) (step S718). Then, the process proceeds to step S720.

  If the value of the continuous effect counter is not 1, or if neither the big bonus (1) nor the big bonus (2) has been won, information indicating the setting status of the winning flag stored in the RAM 122; With reference to the information indicating the stop status of the reels 3L, 3C, and 3R, one of the three virtual reels is stopped in accordance with the stopped reels 3L, 3C, and 3R, and is derived to the variable display device 2. The symbol corresponding to the selected symbol is derived to the virtual reel. Again, the winning display mode is derived to the virtual reel only when winning a bell, cherry or replay, and even when winning a regular bonus, big bonus (1), big bonus (2) or JACIN. The same display mode as that at the time of losing is derived for the virtual reel (step S719). Then, the process proceeds to step S720.

  In step S720, it is determined whether all of the reels 3L, 3C, 3R have been stopped based on the information indicating the stop state stored in the RAM 122. If any of the reels 3L, 3C, 3R is not stopped, the process directly returns to step S701. When all of the reels 3L, 3C, and 3R are stopped, the value of the continuous effect counter and the result corresponding to the winning status of the big bonus (1) or the big bonus (2) are displayed on the liquid crystal display 4 to display the continuous effect. The result of the game for this time is shown to the player (step S721). Further, the value of the continuous effect counter in the RAM 122 is decremented by 1 (step S722), and the process returns to step S701.

  If the received command type is the state command transmitted in step S513, the gaming state indicated by the received state command from the information indicating the gaming state saved in the previous game (that is, the gaming state of the next game) ) And is stored in the RAM 122 (step S723).

  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 S724). Thereafter, the process returns to step S701.

  In this way, in the game in which the continuous effect ends, the big bonus display mode is derived to the virtual reel of the liquid crystal display 4 so that the benefit of the big bonus can be obtained in conjunction with the execution of the continuous effect. Can be shown to the player. However, since the continuous production may be performed even when the big bonus (1) or the big bonus (2) is not won, the big bonus (1) or the big bonus is only performed when the continuous production is performed. It is not known whether or not (2) is won, and the player's interest will not be lost. In addition, when the big bonus (1) or the big bonus (2) is not actually won, the display mode of the big bonus is not derived to the virtual reel even in the game where the continuous production ends, so the player is distrusted. There is no feeling.

  In addition, the trigger for deriving the display mode of the big bonus to the virtual reel is not to win the small part first after winning the big bonus (1) or the big bonus (2), but to actually win the small part first. It may be. In either case of winning a small role or winning a small role, the type of small role that triggers the display mode of the big bonus can be limited to a specific type (for example, a bell). In this case, it is possible to effectively show the player that a big bonus profit is obtained in conjunction with the payout of medals.

  In addition, the Big Bonus (1) or Big Bonus (2) will be awarded in the Big Bonus (1) or Big Bonus (2), the next game won, the game after a predetermined number of games after winning, etc. Regardless of whether or not it has been done, the display mode of the big bonus can be derived to the virtual reel. In this case, when the winning of the big bonus (1) or the big bonus (2) is determined, or when it is determined that the predetermined number of games has passed since the winning of the big bonus (1) or the big bonus (2), It can be determined that the display mode of the big bonus should be derived on the virtual reel of the liquid crystal display 4. For this reason, since it is not necessary to determine the symbol to be derived to the virtual reel every time the reels 3L, 3C, 3R of the variable display device 2 are stopped, the control of the derivation of the symbol to the virtual reel can be easily performed. .

  The timing for deriving the display mode of the big bonus to the virtual reel of the liquid crystal display 4 is in the game from when the big bonus (1) or the big bonus (2) is won until the big bonus based on the corresponding selection ends. In addition to the above, it can be determined that a predetermined condition arbitrarily determined is satisfied.

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

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

  In the above embodiment, due to the arrangement of the symbols on the reels 3L, 3C, 3R, the operation timing of the stop buttons 12L, 12C, 12R when the big bonus (1) or the big bonus (2) is won respectively. It was to win according to. However, it is also possible to win a prize regardless of the operation timing of the stop buttons 12L, 12C, 12R, as the symbols constituting each display mode for each reel are arranged at intervals of 7 frames or less. It is good also as what wins by distribution of the order which operates stop button 12L, 12C, 12R. The same applies to regular bonuses.

  In addition, the big bonus (1) or the big bonus (2) may be controlled so as not to win for a predetermined number of games from the selected game or the selected game. For example, when winning the big bonus (1) or the big bonus (2), it is assumed that the replay is always duplicated. In this case, since the replay is derived in preference to the big bonus (1) or the big bonus (2), the game won by the big bonus (1) or the big bonus (2) wins the prize. You can avoid it. Alternatively, during the predetermined number of games after winning the big bonus (1) or the big bonus (2), the big bonus (1) or the big bonus (2) regardless of the operation timing of the stop buttons 12L, 12C, 12R. The reels 3L, 3C, and 3R may be stopped and controlled so as not to win.

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

  In the above embodiment, even if the big bonus (1) or the big bonus (2) is won, the gaming state remains normal, and the probability of winning the replay does not change. On the other hand, it controls RT (Replay Time) that makes the probability of winning a replay higher than the normal gaming state between winning the big bonus (1) or the big bonus (2) and winning. It is good. Since the game state is controlled by RT, the replay winning probability is increased, and even if the player does not look forward, it will win a replay, bell, and cherry that will not be missed in most games, so a big bonus (1 ) Or Big Bonus (2) can be prevented from being noticed by the player.

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

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

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

  In the above embodiment, the big bonus medium signal is not output when the big bonus (1) or the big bonus (2) is won and the gaming state is controlled to the big bonus, but the big bonus (1 ) Or Big Bonus (2), and when the first small role is won, the output is started. When the small bonus is first won after winning the big bonus (1) or the big bonus (2), the display mode of the big bonus may be derived to the virtual reel here.

  However, when the big bonus (1) or big bonus (2) is won at the time of winning the first small role, the display mode of the big bonus is derived to the virtual reel without winning the small role. Therefore, when the display result is derived to the variable display device 2 in the game that won the small role first after winning the big bonus (1) or the big bonus (2), the big bonus (1) or the big bonus is displayed as the display result. Regardless of whether (2) is derived or bell or cherry is derived, it is possible to start outputting the big bonus medium signal.

  However, in any case, the gaming state of the slot machine 1 cannot be accurately monitored from the outside only by such a big bonus medium signal. Thus, two types of big bonus medium signals may be output from the external output board 105 to the outside. One type is the same big bonus medium signal as in the above embodiment. The other one is a big bonus medium signal that is always output when the big bonus medium flag is set and indicates whether or not the gaming state is the big bonus. The other type may be output after winning the big bonus (1) or the big bonus (2) until the same big bonus medium signal as in the above embodiment is started to be output. .

  By outputting two types of big bonus medium signals in this way, an effect by an external device in accordance with the derivation of the display mode of the big bonus on the virtual reel, or in accordance with the payout of the first medal in the big bonus The information about whether the gaming state is a big bonus can be accurately collected by an external computer device.

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

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

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

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

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

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

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

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

  In the normal gaming state, when 1 or 2 is set as the bet number, the winning probability of the small role in the internal lottery is lower than when 3 is set as the bet number, and the payout when winning the small role The number of medals can be increased. Further, in a slot machine that can set any one, two, or three bets as the number of bets in the normal gaming state and the small bonus game in the big bonus, the number of determination values is stored in common for all of the setting values 1 to 6. There may be a combination that is stored in common for all of the bets 1 to 3 as well as a combination that is stored. In this case, the storage area for the number of determination values can be reduced according to the number of bets, and the storage capacity can be further reduced.

  In the above embodiment, the number of determination values acquired in accordance with the set value or the like is sequentially added to the random number value for internal lottery, but from the value of random number for internal lottery that acquired the acquired determination value number Subtraction may be performed sequentially, and the result of subtraction may be used as a new random value for internal lottery. When the number of determination values is subtracted from the random number value for internal lottery, the 15th and 14th bits of the random number for internal lottery are set to “0”, and the subtraction result overflows (here, the subtraction result is negative) It can be determined whether or not

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

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

  FIG. 17 is an explanatory diagram of a first modification of the process (step S102) until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. Also in the first modification, the random number extracted from the random number generation circuit 115 is stored in the 16-bit general-purpose register 111GR included in the CPU 111.

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

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

  FIG. 18 is an explanatory diagram of a second modification of the process (step S102) until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. Also in this example, the random number extracted from the random number generation circuit 115 is stored in the 16-bit general-purpose register 111GR included in the CPU 111.

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

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

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

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

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

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

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

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

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

  FIG. 19 is an explanatory diagram of a third modification of the process (step S102) until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. In this example, the signal wirings connecting the random number generation circuit 115 and the sampling circuit 116 are connected so that the order of bits is reversed for each of the upper 8 bits and the lower 8 bits. Accordingly, the data latched by the sampling circuit 116 is reverse in the order of bit arrangement for the upper 8 bits and the lower 8 bits with respect to the data signal output by the random number generation circuit 115.

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

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

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

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

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

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

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

  In the third modification, 11h is subtracted from the upper area data before the final exclusive OR operation (FIG. 19 (i)) of the upper area data and the lower area data (FIG. 19). 19 (e)), rotate 1 bit lower (FIG. 19 (f)), perform exclusive OR operation with lower area data (FIG. 19 (g)), and process upper area data in advance. However, not all of these are necessarily required, and any one or two of them can be applied, and there is no need to process the data in the upper area before the final exclusive OR operation. Good. The upper area data at this time may be the final upper byte data in the random number for internal lottery. The order in which the processes of FIGS. 19E to 19F are performed can be changed to an arbitrary order.

  In addition, the value to be subtracted in FIG. 19 (e) is not limited to 11h, and any value other than 00h can be added or subtracted. In FIG. 19 (f), the rotation is limited to 1 bit in the lower order. It can be rotated up or down by any number of bits up to 7 bits. The data in the lower area subjected to the exclusive OR operation in FIG. 19G may be data obtained by performing a predetermined operation on the data first input to the lower area from the random number generation circuit 115. As a calculation performed on the data in the upper area, a calculation by an arithmetic expression other than this can be applied. Furthermore, the data in the save area that is subjected to the exclusive OR operation on the data in the upper area in FIG. 19 (i) may be data that is first input to the lower area from the random number generation circuit 115. Data obtained by performing a predetermined calculation different from (e) to (g) may be used.

  Further, the final lower byte data in the random numbers for internal lottery may be the data that is first input from the random number generation circuit 115 to the lower area as it is. The data in the save area after adding 78h in FIG. 19 (h) may be the final lower byte data in the random number for internal lottery. Alternatively, 78h may be added to the data of the result of the exclusive OR operation stored in the lower area in FIG. 19G to obtain the final lower byte data. Furthermore, as a calculation to be performed on the data in the lower area, a calculation based on another calculation formula may be applied, and the calculation result may be the final lower byte data in the random number for internal lottery.

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

  On the other hand, when the instruction set of the CPU 111 is the one-address method, for example, when subtraction as shown in FIG. 19 (e) is performed, the data stored in the upper area of the RAM 112 is first stored in an accumulator (general register ), 11h is subtracted from the accumulator data, and the subtraction result data is stored again in the accumulator. Here, when the data stored in the upper area of the RAM 112 is loaded into the accumulator, the accumulator effectively acts as the upper area. Here, the accumulator still operates on the data in the upper area. It is not necessary to store the data in the upper area of the RAM 112 yet.

  In FIG. 19 (f), the accumulator data in which the result of the subtraction in FIG. 19 (e) is stored is rotated bit by bit and the result data is stored again in the accumulator. In FIG. 19G, the data stored in the lower area of the RAM 112 is subjected to exclusive OR operation for each bit with respect to the accumulator data in which the result of the operation of FIG. Is stored in the accumulator. At this point, since the accumulator is still functioning as the upper area of the RAM 112, the accumulator data may be stored in the lower area of the RAM 112 in FIG. 19 (g) → (j).

  Further, in FIG. 19 (h), the data in the save area of the RAM 112 is loaded into the accumulator. However, the accumulator functions as the save area here, and 11h is added to the accumulator data and stored in the accumulator. In FIG. 19 (i), the accumulator data is exclusive ORed with the data in the upper area of the RAM 112 for each bit, and the result is stored in the accumulator, but the result of the exclusive OR operation is stored. After that, the accumulator again acts as the upper region.

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

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

  In the RAM 112, the same upper area and lower area are used both for the area for storing the 2n-bit numerical data fetched from the sampling circuit 116 and for the area for storing the finally generated random numbers for internal lottery. However, separate areas may be used. For example, if a 2-byte random number area that stores the finally generated random numbers for internal lottery is provided separately from the upper and lower areas, the upper area data is stored in the lower bytes of the random area. Then, the result data of the exclusive OR operation of FIG. 19 (i) may be stored in the upper byte of the random number area.

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

  The method for generating random numbers for internal lottery in the third modification can change the processes of FIGS. 19A to 19D as shown in FIGS.

  In the example of FIG. 20, the random number generated by the random number generation circuit 115 is changed in the order of bits in the upper 8 bits and the lower 8 bits as in the case of FIGS. (A) to (b). Next, the upper 8 bits of the random number taken by the sampling circuit 116 are taken into the upper area of the RAM 112 via the upper port, and the lower 8 bits are taken into the lower area of the RAM 112 via the lower port (b) to (d). Thereafter, the numerical data stored in the upper byte and the numerical data stored in the lower byte may be exchanged by software processing to obtain a random number before processing (e).

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

  In the example of FIG. 21, the connection of wiring between the random number generation circuit 115 and the sampling circuit 116 is not reversed. First, the random numbers generated by the random number generation circuit 115 are converted into the sampling circuit 116 in the bit arrangement order as they are. (A) to (b). Next, the upper 8 bits of the random number taken by the sampling circuit 116 are taken into the upper area of the RAM 112 via the upper port, and the lower 8 bits are taken into the lower area of the RAM 112 via the lower port (b) to (d).

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

  In the example of FIG. 22, the wiring between the random number generation circuit 115 and the sampling circuit 116 is reversed between the upper byte and the lower byte, and is connected so that the bit order does not change in each byte. . Here, the random number generated by the random number generation circuit 115 is taken into the sampling circuit by switching the upper byte and the lower byte (a) to (b). Next, the upper 8 bits of the random number taken by the sampling circuit 116 are taken into the upper area of the RAM 112 via the upper port, and the lower 8 bits are taken into the lower area of the RAM 112 via the lower port (b) to (d).

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

  In the example of FIG. 23, the wiring between the random number generation circuit 115 and the sampling circuit 116 is completely connected in reverse order. Here, the sampling circuit 116 takes in the order of the random number bits generated by the random number generation circuit 115 in the reverse order (a) to (b). Then, the upper byte and lower byte of the random number fetched by the sampling circuit 116 may be fetched as they are into the upper area and lower area of the RAM 112 via the upper port and lower port as they are (b) to (d).

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

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

  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 the control method that performs the removal control so that the symbols in FIG.

  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. However, the liquid crystal display 4 was larger and configured to be easily visible. However, a variable display device may be provided at the size and position of the liquid crystal display 4 described above, or a liquid crystal display may be provided at the position of the variable display device 2. Further, as the variable display device, a device that virtually displays a symbol on a display device such as a liquid crystal display device may be used in the same manner as the virtual reel of the liquid crystal display 4 described above. On the other hand, an effect variable display device composed of effect reels corresponding to the three reels 3L, 3C, 3R of the variable display device 2 may be applied instead of the virtual reel displayed on the liquid crystal display 4. .

  In the above-described embodiment, the slot machine to which medals are applied as a game medium used for setting a bet number or giving a valuable value associated with winning has been described as an example. However, the slot machine embodying the present invention may be a slot machine (so-called parrot) to which a game ball used in a pachinko gaming machine is applied as a game medium.
