Description

The present invention relates to a gaming machine such as a pachinko gaming machine.

Conventionally, for example, in a pachinko gaming machine, which is one of the gaming machines, when a pachinko ball wins a prize at the starting winning opening, the symbol displayed on the image display device starts to fluctuate, and after a certain period of time, the symbol is stopped and the stopped symbol is displayed. A jackpot game is played when a specific combination is matched. In the jackpot game, the big winning opening is opened a predetermined number of times, and the player can greatly increase the number of playing balls by inserting the game ball into the big winning opening. Further, in recent pachinko gaming machines, opportunities to increase the number of gaming balls are provided in addition to the above-mentioned jackpot games.

As one of such opportunities, a gaming machine equipped with a small hit rush has been proposed. The small hit rush shifts the gaming machine to a gaming state in which the probability of winning a small hit is set high, and by frequently winning small hits, an opportunity to open the big winning opening is provided and the number of game balls is gradually increased. (For example, Japanese Patent Application Laid-Open No. 2018-89012).

JP-A-2018-89012

However, in a gaming machine equipped with the above-mentioned small hit rush, it is necessary to perform the small hit rush in a state without time reduction (without electric chew support) according to the rules, so it is normal even in a state without time reduction compared to other models. It is necessary to raise the winning probability of the symbol to some extent. However, if the winning probability of the normal symbol is increased without shortening the time, it is possible to play a game aiming at opening the electric chew even in the normal state where the small hit rush has not been started. Such a game is not assumed by the manufacturer side or the game store side, and there is a problem that the game behavior is different from the assumption.

The present invention has been made to solve the above-mentioned conventional problems, and in a low-probability time-saving state in which the winning probability of a normal symbol is low and a pattern having a long fluctuation time is selected as the fluctuation pattern of the normal symbol. Furthermore, by making it possible to select one of multiple patterns with different fluctuation times as the fluctuation pattern of the normal symbol, a game that prevents the game aiming at opening the electric chew in a normal state that the manufacturer side or the game store side does not anticipate. The purpose is to provide an opportunity.

In order to achieve the above object, the gaming machine according to the present invention is provided in a flow-down area in which a game ball flows down and in the flow-down area, and is provided with a winning opening for a normal symbol corresponding to a normal symbol and a winning opening for a normal symbol. A winning / failing determination means for a normal symbol that executes a winning / failing judgment when the game ball wins a prize, and a variation pattern selection that selects a fluctuation pattern of the normal symbol when the game ball wins a prize in the winning opening for the normal symbol. A gaming machine comprising means and ordinary symbol changing means for performing variation display and stop display of a normal symbol indicating a hit / fail determination result by the normal symbol hit / fail determination means according to a selected variation pattern. The states are a low probability no time saving state in which the winning probability of the normal symbol winning / failing determination means is low and a pattern having a long fluctuation time is selected as the fluctuation pattern of the ordinary symbol, and the winning probability of the ordinary symbol winning / failing determining means. Includes a high-probability time-saving state in which a pattern having a higher probability than the low-probability time-saving no state and a pattern having a shorter fluctuation time than the low-probability time-saving no state is selected as a fluctuation pattern of a normal symbol. In the none state, the first state in which the pattern with the fluctuation time of the first time is selected as the fluctuation pattern of the normal symbol, and the pattern of the second time in which the fluctuation time is longer than the first hour are selected as the fluctuation pattern of the normal symbol. The second state to be performed includes.

According to the gaming machine according to the present invention having the above configuration, in a low probability no time reduction state in which the winning probability of the normal symbol is low and a pattern having a long fluctuation time is selected as the fluctuation pattern of the normal symbol, the normal symbol is further subjected to. By making it possible to select one of a plurality of patterns having different fluctuation times as the fluctuation pattern, for example, in a gaming state where it is desired to suppress the opening of the electric chew such as a normal state, a fluctuation pattern having a longer fluctuation time of the normal symbol is selected. This makes it possible to suppress the opening of the electric chew. As a result, it is possible to prevent a game aimed at opening an electric chew that is not expected by the manufacturer or the game store.

[Explanation of game status]
Next, the gaming state of the pachinko gaming machine 1 will be described. The special symbol display and the normal symbol display 53 of the pachinko gaming machine 1 are provided with a probability variation function and a variation time shortening function, respectively. The state in which the probability fluctuation function of the special symbol display is operating is called a "high probability state", and the state in which it is not operating is called a "normal probability state (non-high probability state)". In the high probability state, the jackpot probability is higher than in the normal probability state.
Further, the state in which the fluctuation time shortening function of the special symbol display is operating is called a "time saving state", and the state in which it is not operating is called a "non-time saving state". In the time saving state, the fluctuation time of the special symbol (the time required from the start of the fluctuation display to the final display) is shorter than that in the non-time saving state.

The probability fluctuation function and the fluctuation time shortening function of the special symbol display may be operated at the same time, or only one of them may be operated. The probability fluctuation function and the fluctuation time shortening function of the normal symbol display 53 operate in synchronization with the fluctuation time shortening function of the special symbol display. That is, the probability fluctuation function and the fluctuation time shortening function of the normal symbol display 53 operate in the time saving state and do not operate in the non-time saving state. Therefore, in the time-saving state, the probability of being judged as a hit in the lottery of ordinary symbols is higher than in the non-time-saving state. That is, when the probability fluctuation function of the normal symbol display 53 is activated, the normal symbol that the normal symbol display 53 confirms and displays is determined to be a winning symbol (in the lottery of the normal symbol, it is determined to be a hit) as compared with the case where the normal symbol display 53 is not activated. The probability of becoming a normal symbol indicating that it has been done) increases.

Further, in the time-saving state, the fluctuation time of the normal symbol is shorter than that in the non-time-saving state. For example, the fluctuation time of a normal symbol is 5 seconds or 300 seconds in the non-time saving state, but 1 second in the time saving state. Further, in the time saving state, the opening time of the normally variable winning device 20 is longer than in the non-time saving state. That is, the opening time extension function of the normally variable winning device 20 is operating. In addition, in the time saving state, the number of times the normal variable winning device 20 is opened in the auxiliary game is larger than in the non-time saving state. That is, the function of increasing the number of times of opening of the normally variable winning device 20 is operating. The auxiliary game is a game in which the second starting port 22 is opened and closed in an opening pattern according to the current game state when the definitely displayed normal symbol is a predetermined specific ordinary symbol. In the present embodiment, the fluctuation pattern of the normal symbol is relatively short (5 seconds), especially in the non-time saving state (the winning probability of the normal symbol is low and the fluctuation time of the normal symbol is long). There are two types of fluctuation patterns, which are particularly long (for example, 300 seconds). Further, the non-time saving state is applied when the pachinko gaming machine 1 is in the normal state and when it is in the high probability state and is in the small hit rush described later. Then, a fluctuation pattern in which the fluctuation time of the normal symbol is relatively short (5 seconds) is selected during the small hit rush, and a particularly long fluctuation pattern (for example, 300 seconds) is selected in the normal state during the small hit rush.

When the probability fluctuation function and the fluctuation time shortening function of the normal symbol display 53 and the opening time extension function and the opening number of times increasing function of the normal variable winning device 20 are operating, these functions are not operating. In comparison with the above, the normally variable winning device 20 is opened frequently, and the game ball frequently wins the second starting port 22. As a result, the ratio of the number of prize balls to the number of shot balls becomes high, so that the player can aim for a big hit without significantly reducing the number of game balls on hand. In this way, under the condition that the probability fluctuation function and the fluctuation time shortening function of the normal symbol display 53 and the opening time extension function and the opening number of times increasing function of the normal variable winning device 20 are operating, the normal variable winning is performed. The control that supports the winning of the second starting port 22 by the device 20 is called electric support control.
In the pachinko gaming machine 1 of the present embodiment, when the game ball passes through a specific area (V winning area) inside the second big winning opening 35 (FIG. 1) during the big hit game after winning the special big hit described later. The gaming state after the jackpot game is completed is a high-probability state and a time-saving state in which the electric support control is performed and a time-saving state, or a high-probability state and a time-saving state (small hit rush) in which the electric support control is not performed. This game state ends when the variable display of the special symbol is executed a predetermined number of times, or when the big hit is won next time and the big hit game is executed. In this embodiment, it will continue until the next big hit is won.

In addition, even if the special jackpot is won, if the game ball does not pass through the specific area (V winning area) inside the second jackpot 35 (FIG. 1) during the jackpot game, or if the normal jackpot is won. In the game state after the jackpot game is completed, the electric support control is performed and the normal probability state and the time saving state are set. This game state ends when a predetermined number of times (for example, 100 times) of variable display of the special symbol is executed, or when a big hit is won and the big hit game is executed.
When playing the pachinko gaming machine 1 for the first time, the gaming state after the power is turned on is a normal probability state and a non-time saving state (normal state) without performing electric support control.

[Big hit judgment table]
The jackpot determination table Ta1 shown in FIG. 5 is a table referred to when the game control microcomputer 61 (FIG. 3) executes a jackpot determination as to whether or not it is a jackpot. The jackpot determination table Ta1 is configured by associating a game state with a jackpot random number. The jackpot random number is a random number selected from the jackpot random numbers generated by the jackpot random number counter. The computer program for operating the jackpot random number counter is stored in the ROM 63, and when the CPU 62 executes the computer program, the jackpot random number counter operates and a jackpot random number is generated. The jackpot random number counter may use a random number generation circuit such as a counter IC. In the present embodiment, the jackpot random number counter counts a total of 65536 jackpot random numbers from 0 to 65535. That is, a total of 65536 jackpot random numbers from 0 to 65535 are generated. In the present embodiment, a total of 165 jackpot random numbers, 0 to 164, are set in the jackpot determination table Ta1 as jackpot random numbers when the game state is the normal probability state. When the jackpot random number acquired from the jackpot random number counter is any of 0 to 164 when the game state is the normal probability state, the game control microcomputer 61 determines that the jackpot is a jackpot in the jackpot determination, and out of 0 to 65535. If it is other than 0 to 164, it is not a big hit, that is, it is determined to be a loss. Further, in the case where it is determined to be lost in the lottery of the first special symbol (lottery of special figure 1), especially when the jackpot random number acquired from the jackpot random number counter is any of 165 to 264, a small hit. Is determined. On the other hand, in the case where it is determined to be lost in the lottery of the second special symbol (lottery of special figure 2), especially when the jackpot random number acquired from the jackpot random number counter is any of 165 to 65434. It is judged as a small hit. That is, even if the big hit is not won in the lottery of the second special symbol, the small hit will be won with an extremely high probability.

Further, in the present embodiment, a total of 650 jackpot random numbers from 0 to 649 are set in the jackpot determination table Ta1 as jackpot random numbers when the gaming state is in the high probability state. That is, more jackpot random numbers are set than in the normal probability state, and the probability of being determined as a jackpot in the jackpot determination is higher than in the normal probability state. When the jackpot random number acquired from the jackpot random number counter is any of 0 to 649 when the game state is in the high probability state, the game control microcomputer 61 determines that the jackpot is a jackpot in the jackpot determination, and out of 0 to 65535. If it is other than 0 to 649, it is not a big hit, that is, it is determined to be a loss. Further, in the case where it is determined to be lost in the lottery of the first special symbol (lottery of special figure 1), especially when the jackpot random number acquired from the jackpot random number counter is any of 650 to 749, a small hit. Is determined. On the other hand, in the case where it is determined to be lost in the lottery of the second special symbol (lottery of special figure 2), especially when the jackpot random number acquired from the jackpot random number counter is any of 650 to 65919. It is judged as a small hit. That is, even if the big hit is not won in the lottery of the second special symbol, the small hit is won with an extremely high probability.

[Collision detection table]
The normal figure hit determination table Ta2 shown in FIG. 6 is a table that the game control microcomputer 61 (FIG. 3) refers to when executing the determination of whether or not the normal symbol is a hit. The normal figure hit determination table Ta2 is configured by associating a game state with a random number per normal figure. The random number per normal figure is a random number selected from the random number counter as the game ball passes through the gate 12. In the present embodiment, the normal figure hit determination table Ta2 is set to 0 to 254 as a random number per normal figure when the game state is a high probability state (that is, a state in which electric support control is performed) in which the winning probability of the normal symbol is high. A total of 255 hit random numbers are set. The game control microcomputer 61 determines that the random number per normal figure acquired from the random number counter is any of 0 to 254 when the game state is a high probability state in which the winning probability of the normal symbol is high, and determines that the game is 0. If it is other than ~ 254, it is determined that it is not a hit, that is, it is a loss. On the other hand, the normal figure hit detection table Ta2 has a total of 100, 0 to 99, as a random number per normal figure when the game state is a low probability state in which the winning probability of the normal symbol is low (that is, a state in which the electric support control is not performed). Random numbers are set for each hit. The game control microcomputer 61 determines that the random number per normal figure acquired from the random number counter is any of 0 to 100 when the game state is a low probability state in which the winning probability of the normal symbol is low, and determines that the game is 0. If it is other than ~ 100, it is determined that it is not a hit, that is, it is a loss.

[Big hit type judgment table]
The jackpot type determination table Ta3 shown in FIG. 7 is a table that the game control microcomputer 61 (FIG. 3) refers to when executing the jackpot type determination when it is determined to be a jackpot. The jackpot type determination table Ta3 is configured by associating the type of lottery (whether the lottery of special figure 1 or the lottery of special figure 2) with the random number of the jackpot type. The jackpot type random number is a random number selected from the jackpot type random numbers generated by the jackpot type random number counter. The computer program for operating the jackpot type random number counter is stored in the ROM 63, and when the CPU 62 executes the computer program, the jackpot type random number counter operates and the jackpot type random number is generated. The jackpot type random number counter may use a random number generation circuit such as a counter IC. In the present embodiment, the jackpot type random number counter counts a total of 10 jackpot type random numbers from 0 to 9. That is, a total of 10 jackpot type random numbers 0 to 9 are generated. In the pachinko gaming machine 1 of the present embodiment, the types of jackpots include "10R special jackpot (small hit rush rush)", "10R special jackpot (small hit rush non-rush)", and "10R normal jackpot". Then, in the pachinko gaming machine 1, as shown in FIG. 7, in the lottery of the first special symbol (lottery of special figure 1), if the jackpot type random number is a value within the range of 0 to 1, "10R special jackpot (10R special jackpot) It is judged that the player has won the "small hit rush rush)", and if the random number of the big hit type is 2 to 5, it is judged that the "10R special big hit (small hit rush non-rush)" has been won. Judged as "10R normal jackpot". On the other hand, in the second special symbol lottery (special figure 2 lottery), if the jackpot type random number is within the range of 0 to 4, it is determined that the "10R special jackpot (small hit rush rush)" has been won. If the jackpot type random number is 5 to 6, it is determined that the player has won the "10R special jackpot (small hit rush non-rush)", and if it is any other value, it is determined to be the "10R normal jackpot".

Here, the special jackpot is a jackpot that operates the first big prize device 30 and the second big prize device 33 in an open pattern that allows the game ball to pass through the specific area (V winning area) during the big hit game. be. The normal jackpot is a jackpot that operates the first big winning device 30 and the second big winning device 33 in an open pattern in which it is practically impossible for the game ball to pass through the specific area (V winning area) during the big hit game. Is.

In addition, if the 10R special jackpot (small hit rush rush) is won and the game ball passes into a specific area (V winning area) during the jackpot game, the game rushes into the "small hit rush" after the jackpot game, and the next time. Continue until you hit the jackpot. Here, as shown in FIG. 8, in the "small hit rush", the jackpot probability of the special symbol is in a high probability state, but the fluctuation time shortening function of the special symbol does not function. On the other hand, the jackpot probability of the normal symbol becomes a low probability state, and the fluctuation time shortening function of the normal symbol does not work. However, a relatively short 5 seconds is usually selected as the fluctuation time of the symbol. As a result, although it is not in the electric support state, the fluctuation time of the normal symbol is short, and the winning probability of the normal symbol is relatively high (about 1 / 2.5), although it is not as high as the probability change state and the time saving state described later. It will be released to some extent. Further, in the "small hit rush" state, the function of shortening the fluctuation time of the special symbol does not work, so that the holding of the special symbol 2 is slowed down. Therefore, by hitting right, the player can enter the ball into the second starting port 22 to the extent that the hold of the special figure 2 is not exhausted. On the other hand, in Special Figure 2, the probability of winning a small hit is set extremely high, so the player wins consecutively in a small hit and the first big winning opening 32 is opened, so that the player hits right. By doing so, it becomes possible to gradually increase the number of game balls.

In addition, if the 10R special jackpot (small hit rush non-rush) is won and the game ball passes into a specific area (V winning area) during the jackpot game, the ball enters the "probability change state" after the jackpot game, and the next time. Continue until you hit the jackpot. Here, as shown in FIG. 8, in the "probability change state", the jackpot probability of the special symbol is in a high probability state, and the function of shortening the fluctuation time of the special symbol also functions. On the other hand, the jackpot probability of the normal symbol is also in a high probability state, and the function of shortening the fluctuation time of the normal symbol also functions. As a result, it becomes a so-called electric support state, and the player can enter the second starting port 22 one after another without running out of the hold of special figure 2 without significantly reducing the number of game balls by hitting right. Become. In the "probability change state", the electric chew is almost always released, so the right-handed game ball wins with priority over the second starting port 22, and even if a small hit is won, the first big winning opening The 32 is configured so that almost no game ball enters. Therefore, it is basically designed so that the number of game balls does not increase when the ball is in the "probability change state". Regarding the small hit in the "probability change state", the first large winning opening 32 may be opened and closed in a manner in which it is substantially impossible to enter the first large winning opening 32.

On the other hand, if the 10R normal jackpot is won, or even if the 10R special jackpot is won but the game ball does not pass through the specific area (V winning area) during the jackpot game, the "time reduction state" is achieved after the jackpot game. It continues until the next big hit, up to a predetermined number of times (for example, 100 rotations of fluctuation of the special figure). Here, as shown in FIG. 8, in the "time saving state", the jackpot probability of the special symbol is a low probability state, but the function of shortening the fluctuation time of the special symbol functions. On the other hand, the jackpot probability of the normal symbol is in a high probability state, and the function of shortening the fluctuation time of the normal symbol also functions. As a result, it becomes a so-called electric support state, and the player can enter the second starting port 22 one after another without running out of the hold of special figure 2 without significantly reducing the number of game balls by hitting right. Become. In the "probability change state", the electric chew is almost always released, so the right-handed game ball wins with priority over the second starting port 22, and even if a small hit is won, the first big winning opening The 32 is configured so that almost no game ball enters. Therefore, it is basically designed so that the number of game balls does not increase when the player is in the "time saving state". Regarding the small hit in the "time saving state", the first large winning opening 32 may be opened and closed in a manner in which it is substantially impossible to enter the first large winning opening 32.

Then, when a predetermined number of times (for example, 100 rotations of fluctuation of the special figure) elapses without a big hit in the above "time saving state", the state shifts to the "normal state". Here, as shown in FIG. 8, in the "normal state", the jackpot probability of the special symbol is a low probability state, and the fluctuation time shortening function of the special symbol does not function. On the other hand, the jackpot probability of the normal symbol is also in a low probability state, and the function of shortening the fluctuation time of the normal symbol does not work. In addition, a particularly long 300 seconds is selected as the fluctuation time of the normal symbol. Here, in the "normal state", the winning probability of the normal symbol is relatively high (about 1 / 2.5), although it is not as high as the above-mentioned probability variation state or time saving state. However, in the "normal state", the fluctuation time of the normal symbol is extremely long, so even if the player strikes right and passes the game ball through the gate 12, the electric chew only opens very rarely. , The electric chew is basically closed. Therefore, it is possible to prevent a game aimed at opening the electric chew, which is not expected by the manufacturer or the game store.

[Reach judgment table]
The reach determination table Ta4 shown in FIG. 9 is used when the game control microcomputer 61 (FIG. 3) determines whether or not to select a special figure variation pattern in which reach appears when the result of the jackpot determination is a loss. It is a table to be referred to. Here, the reach is a state in which there is only one special symbol that is variablely displayed among a plurality of special symbols, and it depends on which special symbol the variablely displayed special symbol is confirmed and displayed. It is a state where it is a combination of special symbols indicating a big hit. Further, the reach is a state in which only one effect symbol that is variablely displayed is left among the effect symbols that are variablely displayed in each of the plurality of display areas of the effect display device 7, and the effect display is variable. It is a state in which a combination of jackpot effect symbols is used depending on which effect symbol is confirmed and displayed.
For example, when one of the combinations of jackpot effect symbols is "777", "7" is definitely displayed as the left effect symbol 9L in the left effect symbol display area, and as the right effect symbol 9R in the right effect symbol display area. “7” is definitely displayed, and the medium effect symbol 9C is variablely displayed in the medium effect symbol display area. The concept of reach includes a state in which the middle effect symbol 9C is scrolling, a state in which it is shaking, a state in which enlargement and reduction are repeated, and the like.

The reach random number is a random number for determining whether or not to select the special figure fluctuation pattern in which the reach appears when the result of the jackpot determination is a loss. The reach determination table Ta4 is configured by associating a game state with a reach random number. The reach random number is a random number selected from the reach random numbers generated by the reach random number counter. In the present embodiment, the reach random number counter counts a total of 256 reach random numbers from 0 to 255. That is, a total of 256 reach random numbers from 0 to 256 are generated. The computer program for operating the reach random number counter is stored in the ROM 63, and when the CPU 62 executes the computer program, the reach random number counter operates and a reach random number is generated. In the present embodiment, a total of 28 reach random numbers 0 to 27 are set as reach random numbers when the game state is a non-time saving state (of a special symbol). When the reach random number acquired from the reach random number counter is any of 0 to 27 when the game state is the non-time saving state, the game control microcomputer 61 determines that there is reach in the reach determination, and 0 to 255. If it is other than 0 to 27, it is determined that there is no reach.

Further, in the present embodiment, a total of 12 reach random numbers 0 to 11 are set as the reach random numbers when the game state is the time saving state (of the special symbol). If the reach random number acquired from the reach random number counter is any of 0 to 11 when the game state is the time saving state, the game control microcomputer 61 determines that there is reach in the reach determination, and out of 0 to 255. If it is other than 0 to 11, it is determined that there is no reach.
The reach random number determined to have reach is set to be smaller in the time-saving state than in the non-time-saving state. As a result, the probability of being determined to have reach in the time-saving state is lower than in the non-time-saving state. That is, since the probability of determining that there is no reach is high, the probability of selecting the special figure fluctuation pattern without reach is high accordingly. Therefore, in the time saving state, the pace of digestion of the number of reserved special figures becomes faster.

Note that FIG. 9 basically shows a reach determination table corresponding to the first special symbol. The reach determination table corresponding to the second special symbol may have the same contents as the first special symbol, or may be a different table.

[Public map fluctuation pattern selection table]
The normal figure fluctuation pattern selection table Ta5 shown in FIG. 10 is a table that the game control microcomputer 61 (FIG. 3) refers to when determining the normal figure fluctuation pattern (more specifically, the fluctuation time of the normal symbol) by lottery. be. The normal figure fluctuation pattern selection table Ta5 is configured by associating a game state, a hit determination result, a fluctuation time, and a stop time.

When the game state is a non-time saving state (of a normal symbol) and a small hit rush state in particular, the fluctuation time is 5,000 ms in both the case where the hit judgment of the normal symbol is determined to be a hit and the case where the judgment is a loss. It is selected, and 500 ms is selected as the stop time of the normal symbol, that is, the time when the normal symbol is confirmed and displayed.

In addition, when the game state is a non-time saving state and is particularly a normal state, 300,000 ms is selected as the fluctuation time in both the case where the hit determination of the normal symbol is determined to be a hit and the case where the game is a loss and the normal symbol is determined. 500ms is selected as the stop time of, that is, the time when the normal symbol is confirmed and displayed.

In addition, when the game state is a time saving state, 1,000 ms is selected as the fluctuation time in both the case where the hit determination of the normal symbol is determined to be a hit and the case where the game is determined to be a loss, that is, the stop time of the normal symbol, that is, , 500ms is selected as the time when the normal symbol is confirmed and displayed.

[Special figure fluctuation pattern selection table]
The special figure variation pattern selection table Ta6 shown in FIG. 11 is a table that the game control microcomputer 61 (FIG. 3) refers to when determining the special figure variation pattern by lottery. The special figure fluctuation pattern selection table Ta6 includes a game state, a judgment (big hit judgment, small hit judgment, and reach judgment) result, a special figure hold number, a fluctuation pattern random number, a special figure fluctuation pattern, and a fluctuation time. It is configured in association with the stop time. The jackpot type may be associated with each other. The variation effect pattern in the special figure variation pattern selection table Ta6 is a variation effect pattern in which the effect display device 7 variably displays the effect corresponding to the selected special figure variation pattern, and is described for reference. The variation pattern random number is a random number selected from the variation pattern random numbers generated by the variation pattern random number counter. In the present embodiment, the variation pattern random number counter counts a total of 100 variation pattern random numbers from 0 to 99. That is, a total of 100 fluctuation pattern random numbers from 0 to 99 are generated. The computer program for operating the variation pattern random number counter is stored in the ROM 63, and when the CPU 62 executes the computer program, the variation pattern random number counter operates and the variation pattern random number is generated.

When the game state is a non-time saving state (of a special symbol), it is determined as a jackpot in the jackpot judgment, and if the fluctuation pattern random number acquired from the fluctuation pattern random number counter is any of 0 to 94, the special figure reservation number is set. Regardless, the special figure variation pattern P1 is selected. That is, the probability that the special figure variation pattern P1 is selected is 95%. When the variation pattern random number is any of 95 to 99, the special figure variation pattern P2 is selected regardless of the number of reserved balls. That is, the probability that the special figure fluctuation pattern P2 is selected is 5%. The fluctuation time of the special symbol fluctuation pattern P1 is 400,000 ms, and the stop time of the special symbol, that is, the time during which the special symbol is confirmed and displayed is 500 ms. The fluctuation time of the special symbol fluctuation pattern P2 is 150,000 ms, and the stop time of the special symbol is 500 ms. When the special figure variation pattern P1 is selected, the effect display device 7 displays the SP (super) reach developed from the reach state as the variation effect pattern. Further, when the special figure variation pattern P2 is selected, the effect display device 7 displays the normal reach as the variation effect pattern.

When is any of 0 to 9, the special figure fluctuation pattern P3 is selected regardless of the number of special figure reservations. That is, the probability that the special figure variation pattern P3 is selected is 10%. When the variation pattern random number is any of 10 to 99, the special figure variation pattern P4 is selected regardless of the number of reserved balls. That is, the probability that the special figure fluctuation pattern P4 is selected is 90%. The fluctuation time of the special symbol fluctuation pattern P3 is 400,000 ms, and the stop time of the special symbol is 500 ms. The fluctuation time of the special symbol fluctuation pattern P4 is 150,000 ms, and the stop time of the special symbol is 500 ms. When the special figure variation pattern P3 is selected, the effect display device 7 displays the SP reach developed from the reach state as the variation effect pattern. Further, when the special figure variation pattern P4 is selected, the effect display device 7 displays the normal reach as the variation effect pattern.

In addition, when the game state is a non-time saving state, it is determined that there is a loss, and in the reach determination, it is determined that there is no reach, that is, in the case of a loss without reach, and the number of reserved special figures is 0 to 2. If the variation pattern random number acquired from the variation pattern random number counter is any of 0 to 99, the special figure variation pattern P5 is selected. That is, the probability that the special figure fluctuation pattern P5 is selected is 100%. If the number of special figures held is 3 to 4 and the variation pattern random number acquired from the variation pattern random number counter is any of 0 to 99, the special figure variation pattern P6 is selected. That is, the probability that the special figure variation pattern P6 is selected is 100%. The fluctuation time of the special symbol fluctuation pattern P5 is 10,000 ms, and the stop time of the special symbol is 500 ms. The fluctuation time of the special symbol fluctuation pattern P6 is 5,000 ms, and the stop time of the special symbol is 500 ms. When the special figure variation pattern P5 or the special figure variation pattern P6 is selected, the effect display device 7 displays the normal variation as the variation effect pattern.

Further, when it is determined that the game is a small hit when the game state is the non-time saving state, the special figure variation pattern P7 is selected. The fluctuation time of the special symbol fluctuation pattern P7 is 5,000 ms, and the stop time of the special symbol is 500 ms. Further, when the special figure variation pattern P7 is selected, the effect display device 7 displays a dedicated effect at the time of winning a small hit as a variation effect pattern. Especially during the small hit rush, a special production for the small hit rush is performed.

When the game state is a time saving state (of a special symbol), it is judged as a big hit, and if the fluctuation pattern random number acquired from the fluctuation pattern random number counter is any of 0 to 99, the special figure is held regardless of the number of reserved special symbols. Figure variation pattern P11 is selected. That is, the probability that the special figure variation pattern P11 is selected is 100%. Further, when the game state is a time saving state, it is determined to be lost, and when it is determined to have reach in the reach determination, that is, in the case of loss with reach, the variation pattern random number acquired from the variation pattern random number counter is If it is any of 0 to 99, the special figure fluctuation pattern P12 is selected regardless of the number of reserved special figures. That is, the probability that the special figure variation pattern P12 is selected is 100%.

When the special figure variation pattern P11 or the special figure variation pattern P12 is selected, the effect display device 7 displays the SP reach developed from the reach state as the variation effect pattern.

Further, when the game state is a time saving state, it is determined that there is a loss, and in the reach determination, it is determined that there is no reach, that is, in the case of a loss without reach, and the number of reserved special figures is 0 to 1. If the variation pattern random number acquired from the variation pattern random number counter is any of 0 to 99, the special figure variation pattern P13 is selected. That is, the probability that the special figure variation pattern P13 is selected is 100%. If the number of special figures held is 2 to 4, and the variation pattern random numbers acquired from the variation pattern random number counter are any of 0 to 99, the special figure variation pattern P14 is selected. That is, the probability that the special figure variation pattern P14 is selected is 100%.

The fluctuation time of the special symbol fluctuation pattern P14 is 2,500 ms, and the stop time of the special symbol is 500 ms. When the special figure variation pattern P13 or the special figure variation pattern P14 is selected, the effect display device 7 displays the normal variation as the variation effect pattern.

Further, when it is determined that the game is a small hit when the game state is the time saving state, the special figure variation pattern P15 is selected. The fluctuation time of the special symbol fluctuation pattern P15 is 2,500 ms, and the stop time of the special symbol is 500 ms. Further, when the special figure variation pattern P15 is selected, the effect display device 7 displays a dedicated effect at the time of winning a small hit as a variation effect pattern.

As described above, the probability that the development to SP reach is selected in the non-time saving state is 95% when it is judged as a big hit in the big hit judgment, but it is judged as a loss in the big hit judgment and there is a reach. When it is determined, it is 10%. In addition, the probability that the normal reach stop is selected in the non-time saving state is 5% when it is determined as a jackpot in the jackpot determination, but when it is determined as a loss in the jackpot determination and it is determined that there is reach. Is 90%.
That is, when the effect display device 7 develops to SP reach as a variable effect pattern, there is a high possibility that a big hit will occur. In other words, SP reach is a variation effect pattern in which the degree of expectation for the occurrence of a jackpot is higher than that in the case where the normal reach is stopped.

When the variation pattern P7 is selected as the special figure variation pattern, the exclusive effect at the time of winning the small hit is displayed as the effect content regardless of the effect selection random number acquired from the effect selection random number counter. Especially during the small hit rush, a special production for the small hit rush is performed. Further, when a small hit is won, the first big winning opening 32 is also opened, and the first big winning opening 32 is in a state of being opened until a predetermined number (for example, 5) of game balls are entered or a predetermined time elapses. ..

When the variation pattern P11 is selected as the special figure variation pattern, if the effect selection random number acquired from the effect selection random number counter is any of 0 to 13, after the notice A is performed from the normal variation as the effect content.

Further, when the variation pattern P12 is selected as the special figure variation pattern, if the effect selection random number acquired from the effect selection random number counter is any of 86 to 99, a notice C is performed from the normal variation as the effect content. After that, it becomes reach, further develops into SP reach C, and finally the production content that notifies the loss is selected.

When the variation pattern P13 is selected as the special figure variation pattern, if the effect selection random number acquired from the effect selection random number counter is any of 0 to 50, after performing the notice B from the normal variation as the effect content. The production content that notifies the loss without establishing the reach is selected. Further, when the variation pattern P13 is selected as the special figure variation pattern, if the effect selection random number acquired from the effect selection random number counter is any of 51 to 99, a notice C is performed from the normal variation as the effect content. After that, the production content that notifies the loss without establishing the reach is selected.

When the variation pattern P14 is selected as the special figure variation pattern, the effect content for immediately notifying the loss from the normal variation is selected as the effect content regardless of the effect selection random number acquired from the effect selection random number counter.

When the variation pattern P15 is selected as the special figure variation pattern, the exclusive effect at the time of winning the small hit is displayed as the effect content regardless of the effect selection random number acquired from the effect selection random number counter.

It should be noted that the normal reach A to C have a relatively high expectation of a jackpot than the normal fluctuation, and the SP reach A to C have a relatively high expectation of a jackpot than the normal reach A to C. Further, the SP reach C, which is easily selected at the time of determining the jackpot, is an effect in which the expectation of the jackpot is relatively higher than that of the SP reach A, which is difficult to be selected at the time of determining the jackpot. That is, the degree of expectation increases in the order of normal reach A, normal reach B, normal reach C, SP reach A, SP reach B, and SP reach C.

[Main processing of the game control microcomputer 61]
Next, the main processing executed by the game control microcomputer 61 (FIG. 3) will be described with reference to the drawings.
(Main control process on the main side)
First, the contents of the main control processing on the main side executed by the game control microcomputer 61 will be described with reference to FIG. 17, which shows the contents.
When the power of the pachinko gaming machine 1 is turned on, the game control microcomputer 61 reads out and executes the computer program of the main control process shown in FIG. 17 from the ROM 63 (FIG. 3). The game control microcomputer 61 first makes initial settings (step (hereinafter, abbreviated as S) 1). In this initial setting, for example, stack setting, constant setting, interrupt time setting, CPU62 setting, SIO (Serial Input / Output), PIO (Parallel Input / Output), CTC (Counter / Timer Circuit: interrupt) (Circuit for managing time) is set, various flags, counters and timers are reset. Subsequently, the game control microcomputer 61 executes interrupt prohibition (S2) and executes a normal symbol / special symbol main random number update process (S3). In this normal symbol / special symbol main random number update process, the initial values of the random number counters that generate the jackpot random number, the jackpot type random number, the reach random number, and the variable pattern random number described above are each added by "1" and updated. When the count value of each random number counter reaches the upper limit value, it returns to "0" and is added again by "1". The initial value of each random number counter may be a value other than "0" or may be randomly changed. Further, a numerical value of "2" or more may be added to the count value of each random number counter to update. Further, each random number may be a so-called hardware random number generated by using a known random number generation circuit including a counter IC or the like. When this hardware random number is used, software-based random number update processing (S3) is not required.

Subsequently, the game control microcomputer 61 executes the interrupt permission (S4). While the interrupt is permitted, the main timer interrupt process (S5) can be executed. The main timer interrupt process (S5) is executed based on, for example, an interrupt pulse input to the CPU 62 at a cycle of 4 msec. That is, it is executed in a cycle of 4 msec. Then, between the end of the main timer interrupt process (S5) and the start of the next main timer interrupt process (S5), the normal symbol / special symbol main random number update process (S3) is performed. Initial value update processing of various counters is executed. If an interrupt pulse is input to the CPU 62 in the interrupt prohibited state, the main timer interrupt process (S5) is not started immediately, but is started after the interrupt permission (S4) is executed. NS.

(Main timer interrupt processing)
Next, the contents of the main-side timer interrupt process (S5 in FIG. 17) executed by the game control microcomputer 61 will be described with reference to FIG. 18 showing the contents.
The game control microcomputer 61 executes the output process (S10). In this output process, commands and the like set in the output buffer provided in the RAM 64 (FIG. 3) of the main control board 60 in each process described below are transmitted to the sub control board 100 (FIG. 4) and the payout control board 73 (FIG. 3). Output to 3) etc. In particular, in the present embodiment, the normal symbol fluctuation start command indicating that the normal symbol has started to fluctuate when the normal symbol has started to fluctuate, and the special symbol to indicate that the special symbol has started to fluctuate when the special symbol has started to fluctuate. The special figure fluctuation start command is also output. Subsequently, the game control microcomputer 61 executes the input process (S11). In this input processing, various sensors mainly attached to the pachinko gaming machine 1 (first starting port sensor 11a, second starting port sensor 22a, first large winning opening sensor 32a, second large winning opening sensor 35a, gate Each detection signal detected by the sensor 12a or the like (FIG. 3) is read. Subsequently, the game control microcomputer 61 executes the timer update process (S12). In this timer update process, the subtraction counter operating as a timer is updated (subtracted). Subsequently, the game control microcomputer 61 executes the prize ball control process (S13). In this prize ball control process, a payout command for paying out prize balls according to the type of winning opening is set in the output buffer of the RAM 64 based on the detection signals of various sensors read in the input process (S11). The payout command is a command output to the payout control board 73. Subsequently, the game control microcomputer 61 executes the normal symbol / special symbol main random number update process (S14). This normal symbol / special symbol main random number update process is the same as the normal symbol / special symbol main random number update process (S3) executed in the main side main control process of FIG. That is, the initial value update processing of each random number counter is performed after the execution period of the main timer interrupt processing (S5) and the other periods (main side timer interrupt processing (S5) are completed, and then the next main timer interrupt processing (S5) is completed. It is performed both in the period until the interrupt processing (S5) is started).

Subsequently, the game control microcomputer 61 has a start port sensor detection process (S15), a normal operation process (S16), a special symbol standby process (S17), a special symbol variation process (S18), and other processes (S19), which will be described later. Is executed to end the main timer interrupt process (S5). Other processes (S19) include security control processing for detecting and notifying an illegal prize, magnetic detection processing for detecting and notifying an illegal act using radio waves, and detecting the opening of the front frame 18 (FIG. 1) and the inner frame. The door opening process for notifying is performed, the fraudulent radio wave detection process for detecting and notifying fraudulent activity using radio waves, the impact detection process for detecting and notifying fraudulent activity that causes the pachinko gaming machine 1 to vibrate, and the like. Then, until the next interrupt pulse is input to the CPU 62, the main control processes S2 to S4 are repeatedly executed (FIG. 17), and when the interrupt pulse is input (after about 4 msec), the process is repeated again. The main timer interrupt process (S5) is executed. In the output process (S10) of the main timer interrupt process (S5) executed again, the command set in the output buffer of the RAM 64 (FIG. 3) in the previous main timer interrupt process (S5) is predetermined. It is output to the board.

(Starting port sensor detection process)
Next, the contents of the start port sensor detection process (S15 in FIG. 18) executed by the game control microcomputer 61 will be described with reference to FIG. 19 showing the contents.
The game control microcomputer 61 determines whether or not the game ball has passed through the gate 12 (FIG. 1) (S20), and if it determines that the game ball has passed (S20: Yes), executes the gate passage process (S21). ). In this gate passing process, it is determined whether or not the number of reserved figures is 4 or more, and if the number of reserved figures is not 4, "1" is added to the number of reserved figures and a lottery of ordinary symbols is performed. Performs the process of acquiring and storing the winning random number for the purpose.

Further, in S20, when it is determined that the game ball has not passed through the gate 12 (S20: No), it is determined whether or not the game ball has won the second starting port 22 (FIG. 1) (S22). .. Here, when it is determined that the game ball has won the second starting port 22 (S22: Yes), it is determined whether or not the second special figure reservation number U2 has reached the upper limit value "4" (S23). .. Here, if it is determined that the second special figure reservation number U2 has reached "4" (S23: Yes), the process proceeds to S28, but if the second special figure reservation number U2 has not reached "4". If it is determined (S23: No), 1 is added to the second special figure reservation number U2 (S24). Subsequently, the game control microcomputer 61 executes the second special figure-related random number acquisition process (S25). In this second special figure-related random number acquisition process, the jackpot random number counted by the jackpot random number counter, the jackpot type random number counted by the jackpot type random number counter, the reach random number counted by the reach random number counter, and the fluctuation pattern random number counter count. Fluctuation pattern random numbers are acquired, and each of the acquired random numbers is stored in a storage area corresponding to the current number of second special figure reservations in the second special figure reservation storage unit 64b (FIG. 13). For example, when the current number of reserved second special figures is "3", each random number is stored in the fourth storage area.

Subsequently, the game control microcomputer 61 executes the second start winning command creation process (S26). In this second start winning command creation process, the second start winning command is created based on each random number group stored in the second special figure reservation storage unit 64b in S25. This second start winning command is composed of data indicating that the game ball has won a prize in the second starting port, data indicating each random number stored in the second special figure reservation storage unit 64b in S25, and the like. Subsequently, the game control microcomputer 61 sets the second start winning command created in S26 in the output buffer of the RAM 64 (S27). This set second start winning command is output to the sub control board 100 (FIG. 4) in the output process (S10 in FIG. 18), and the effect control microcomputer 101 is based on each random number included in the second start winning command. And execute the production.

Subsequently, the game control microcomputer 61 determines whether or not the game ball has won the first starting port 11 (FIG. 1) (S28). Here, when it is determined that the game ball has won the first starting port 11 (S28: Yes), it is determined whether or not the first special figure reservation number U1 has reached the upper limit value "4" (S29). .. Here, if it is determined that the first special figure reservation number U1 has reached "4" (S29: Yes), this start port sensor detection process is terminated, but the first special figure reservation number U1 is "4". When it is determined that the number has not reached (S29: No), 1 is added to the first special figure reservation number U1 (S30). Subsequently, the game control microcomputer 61 executes the first special figure-related random number acquisition process (S31). In this first special figure-related random number acquisition process, a jackpot random number, a jackpot type random number, a reach random number, and a fluctuation pattern random number are acquired, and each of the acquired random numbers is stored in the first special figure reservation storage unit 64a (FIG. 12). Of these, it is stored in the storage area according to the current number of reserved first special figures. For example, when the current number of reserved first special figures is "3", each random number is stored in the fourth storage area.

Subsequently, the game control microcomputer 61 executes the first start winning command creation process (S32). In this first start winning command specifying process, the first starting winning command is created based on each random number group stored in the first special figure reservation storage unit 64a in S31. This first start winning command is composed of data indicating that the game ball has won a prize in the first starting port 11, data indicating each random number stored in the first special figure reservation storage unit 64a in S31, and the like. Subsequently, the game control microcomputer 61 sets the first start winning command created in S32 in the output buffer of the RAM 64 (S33). This set first start winning command is output to the sub control board 100 (FIG. 4) in the output process (S10 in FIG. 18), and the effect control microcomputer 101 is based on each random number included in the first start winning command. And execute the production.

(Normal operation processing)
The game control microcomputer 61 performs a normal operation process (S16) following the sensor detection process (S15) (see FIG. 20). As shown in FIG. 20, in the normal operation process (S16), first, it is determined whether or not the normal variable winning device 20 (electric chew) is in operation (S40). If the electric chew is not in operation (S40: No), then it is determined whether or not the stop display of the normal symbol is in progress (S41). If it is not during the stop display of the normal symbol (S41: No), then it is determined whether or not the variable display of the normal symbol is being displayed (S42). Unless the fluctuation display of the normal symbol is being performed (S42: No), it is subsequently determined whether or not the number of reserved balls of the normal symbol is "0" (S43). If the number of reserved balls of the normal symbol is "0" (S43: Yes), this process ends.

If the number of reserved balls of the normal symbol is not "0" in S43 (S43: No), the hit determination process is performed (S44). In the hit determination process (S44), the normal symbol random number counter value stored in the normal symbol hold storage unit 64c is read out, and whether or not the hit is determined is determined based on the normal symbol hit determination table Ta2 shown in FIG. As shown in FIG. 8, the winning probability of the normal symbol differs depending on the current gaming state of the gaming machine. Then, a symbol determination process is performed in which the normal symbol stop symbol data according to the result of the hit determination is set in a predetermined storage area of the RAM 64 (S45). That is, in the symbol determination process (S45), if it is "lost", the data corresponding to the "normal figure lost symbol" is set, and if it is "hit", the data corresponding to the "normal hit symbol" is set.

Subsequently, the game control microcomputer 61 performs a normal symbol fluctuation time determination process (S46). As shown in FIG. 8, the fluctuation time of the normal symbol differs depending on the current gaming state of the gaming machine. In the normal symbol fluctuation time determination process (S46), referring to the normal symbol fluctuation pattern selection table Ta5 shown in FIG. 10, when the game state is a non-time saving state (of the normal symbol) and particularly a small hit rush state, Select a normal symbol fluctuation pattern with a normal symbol fluctuation time of 5,000 ms. Further, when the gaming state is a non-time saving state and is particularly a normal state, a normal symbol fluctuation pattern having a normal symbol fluctuation time of 300,000 ms is selected. Further, when the game state is the time saving state, the normal symbol fluctuation pattern in which the fluctuation time of the normal symbol is 1,000 ms is selected.

Next, the game control microcomputer 61 decrements the number of normally symbol reserved balls by 1 (S47). Then, the storage location (storage area) of each normal figure hold in the normal figure hold storage unit 64c is shifted by one to the side to be read from the current position, and the storage corresponding to the fourth hold in the normal figure hold storage unit 64c is performed. Clear the area (the storage area farthest from the read side) (S48). In this way, the general map hold is digested in the order in which it was held. After that, the game control microcomputer 61 starts the variation display of the normal symbol in the normal symbol variation pattern selected in step S46 (S49). Along with this, in order to notify the sub-control board 100 of the start of fluctuation of the normal symbol, a command for starting the fluctuation of the normal symbol is set.

If the fluctuation display of the normal symbol is being displayed in S42 described above (S42: Yes), then it is determined whether or not the fluctuation time of the normal symbol has elapsed (S50), and if not, the process ends. On the other hand, if it has passed (S50: Yes), the variable display of the normal symbol is stopped at the display result (normal hit symbol or normal lost symbol) according to the determination result of the normal symbol random number (S51). Then, the sub-control board 100 is set with the normal symbol fluctuation stop command for notifying the normal symbol fluctuation stop (S52), and the normal symbol stop time is set (S53) to end this process.

Further, if the stop display of the normal symbol is being displayed in S41 described above (S41: Yes), then it is determined whether or not the stop time of the normal symbol set in S53 has elapsed (S54), and the stop time has not elapsed. If so, finish the process. On the other hand, if it has passed (S54: Yes), it is determined whether or not the normal symbol stop symbol data of the normal hit symbol is set (S55), and if it is not the data of the normal hit symbol (that is, if it is not a hit). (S55: No)), this process is completed. On the other hand, if it is the data of the normal hit symbol (that is, if it is a hit (S55: Yes)), the opening pattern of the electric chew is set (S56). Specifically, if it is in the time saving state, the opening pattern in the time saving state is set as the opening pattern of the electric chew. On the other hand, if it is in the non-time saving state, the opening pattern in the non-time saving state is set as the opening pattern of the electric chew. Then, the electric chew is operated according to the opening pattern set in S56 (S57).

Further, if the electric chew is operating in S40 described above (S40: Yes), then it is determined whether or not the operating time of the electric chew has elapsed (S58), and if not, the process ends. .. On the other hand, if it has passed (S58: Yes), the operation of the electric chew is terminated (S59).

(Special symbol standby processing)
Next, the contents of the special symbol standby process (S17 in FIG. 18) executed by the game control microcomputer 61 will be described with reference to FIG. 21 showing the contents.
The game control microcomputer 61 determines whether or not the second special figure hold number U2 is "0" (S60), and if it determines that it is not "0" (S60: No), the second special figure described later. The special figure jackpot determination process (FIG. 22) is executed (S61). Subsequently, the game control microcomputer 61 executes the second special figure variation pattern selection process (FIGS. 23 and 24), which will be described later (S62). Subsequently, the game control microcomputer 61 subtracts "1" from the second special figure reservation number U2 (S63), and is stored in each storage area of the second special figure reservation storage unit 64b (FIG. 13). The data is shifted one by one to the storage area with the oldest storage order, that is, the side to be read (S64). Subsequently, the game control microcomputer 61 executes the second special figure variation start process (S65). That is, the second special symbol display 52 has the second special symbol in the order in which the game control microcomputer 61 executes the winning / failing determination based on the jackpot random number stored in the second special symbol holding storage unit 64b (FIG. 13). Perform variable display. Further, each time the second special symbol display 52 performs a variable display of the second special symbol, each data stored in each storage area of the second special symbol reservation storage unit 64b has an older storage order. Shifted to storage area.
In this second special symbol variation start process, the variation start command is set in the output buffer of the RAM 64, and the variation display of the second special symbol is started. The fluctuation start command set in the output buffer of the RAM 64 includes the data of the special figure stop symbol set in the second special figure jackpot determination process (FIG. 22) described later and the second special figure fluctuation pattern selection process (FIGS. 23, FIG. The data of the special figure fluctuation pattern set in 24) is included.

Further, when the game control microcomputer 61 determines in S60 that the second special figure reservation number U2 is "0" (S60: Yes), is the first special figure reservation number U1 "0"? If it is determined whether or not it is (S66) and it is determined that it is not "0" (S66: No), the first special figure jackpot determination process (FIG. 22) described later is executed (S67). Subsequently, the game control microcomputer 61 executes the first special figure variation pattern selection process (FIGS. 23 and 24), which will be described later (S68). Subsequently, the game control microcomputer 61 subtracts "1" from the first special figure reservation number U1 (S69), and is stored in each storage area of the first special figure reservation storage unit 64a (FIG. 12). The data is shifted one by one to the storage area with the oldest storage order, that is, the side to be read (S70). Subsequently, the game control microcomputer 61 executes the first special figure variation start process (S71). That is, the first special symbol display 51 has the first special symbol in the order in which the game control microcomputer 61 executes the winning / failing determination based on the jackpot random number stored in the first special symbol holding storage unit 64a (FIG. 12). Perform variable display. Further, each time the first special symbol display 51 performs a variable display of the first special symbol, each data stored in each storage area of the first special symbol reservation storage unit 64a has an older storage order. Shifted to storage area.
In this first special symbol variation start process, the variation start command is set in the output buffer of the RAM 64, and the variation display of the first special symbol is started. The fluctuation start command set in the output buffer of the RAM 64 includes the data of the special figure stop symbol set in the first special figure jackpot determination process (FIG. 22) described later and the first special figure fluctuation pattern selection process (FIGS. 23, FIG. The data of the fluctuation pattern set in 24) is included.

Further, when the game control microcomputer 61 determines in S66 that the first special figure hold number U1 is "0" (S66: Yes), the effect display device 7 displays the standby screen (demo screen for waiting for customers). ) Is displayed (S72). Here, when it is determined that the standby screen is displayed (S72: Yes), the special symbol standby process is completed, and when it is determined that the standby screen is not displayed (S72: No), the standby screen is displayed. The setting process is executed (S73). In this standby screen setting process, a customer waiting standby command for displaying the standby screen is set in the output buffer of the RAM 64 after waiting for the elapse of a predetermined standby time.
Further, in the present embodiment, the variation display of the first special symbol based on the first special figure reservation is performed only when the second special figure reservation number U2 is "0" (S60: Yes). That is, the digestion of the second special figure hold is executed in preference to the digestion of the first special figure hold.

(2nd special figure jackpot judgment process (1st special figure jackpot judgment process))
Next, the contents of the second special figure jackpot determination process (first special figure jackpot determination process): S61 of FIG. 21) executed by the game control microcomputer 61 will be described with reference to FIG. 22 showing the contents. Since the second special figure jackpot determination process (S61 in FIG. 21) and the first special figure jackpot determination process (S67 in FIG. 21) have the same processing flow, they will be described together. Further, when a matter common to the first special figure holding storage unit 64a and the second special figure holding storage unit 64b is explained, it is simply referred to as a special figure holding storage unit.

The game control microcomputer 61 reads out the jackpot random numbers stored in the first storage area (FIGS. 12 and 13) of the special figure reservation storage unit of the RAM 64 (S75), and refers to the jackpot determination table Ta1 (FIG. 5). (S76). Subsequently, the game control microcomputer 61 determines whether or not the probability change flag is ON, that is, whether or not the current game state is a high probability state (S77). The probability variation flag is turned ON when the game ball that has won the second big winning opening 35 (FIG. 1) passes through the specific area (V winning area) during the big hit game. Here, when it is determined that the probability variation flag is not ON, that is, it is in the normal probability state (S77: No), the jackpot random number in the normal probability state is referred to in the jackpot determination table Ta1 and read in S75. Whether or not the same random number as the jackpot random number exists, that is, whether or not the jackpot is a jackpot is determined (S78). For example, when the jackpot random number read in S75 is "7", it is determined as a jackpot because "7" exists in the jackpot random numbers 0 to 164 in the normal probability state in the jackpot determination table Ta1 ( S78: Yes).

When the game control microcomputer 61 determines that the jackpot is a jackpot in S78 (S78: Yes), the game control microcomputer 61 reads out the jackpot type random numbers stored in the first storage area (FIGS. 12 and 13) of the special figure reservation storage unit, and a plurality of them. With reference to the jackpot type determination table Ta3 (FIG. 7) in which the jackpot type is set, the jackpot type is determined (S79). Depending on the type of jackpot, the jackpot symbol of the special figure, the stop symbol of the special figure, the distribution rate, the maximum number of rounds, the jackpot effect symbol, etc. differ. In addition, depending on the type of jackpot, it is also determined whether or not to shift to the "small hit rush", the "probability change state", or the "time saving state" after the jackpot game is completed. Here, the distribution rate is the probability that a predetermined jackpot is selected from a plurality of types of jackpots set in the jackpot type determination table. The maximum number of rounds is the maximum number of rounds that can be executed in a jackpot game.

Subsequently, the game control microcomputer 61 turns on the jackpot flag indicating that the jackpot has been determined in the jackpot determination (S80), and confirms and displays the jackpot symbol of the special figure according to the type of jackpot determined in S79. The special figure stop symbol data of No. 1 is set in the special figure buffer provided in the RAM 64 (FIG. 3) (S81), and the second special figure jackpot determination process is completed. Further, in S78, when it is determined that the hit is not a big hit (S78: No), the hit / fail determination of whether or not it is a small hit is performed (S82). For example, when the jackpot random number read in S75 is "201", it is determined as a small hit because "201" exists in the jackpot random numbers 165 to 65434 in the normal probability state in the jackpot determination table Ta1. (S82: Yes).

When the game control microcomputer 61 determines that it is a small hit in S82 (S82: Yes), the small hit flag indicating that it is determined to be a small hit is turned on (S83), and the special figure stop symbol data is stored in the RAM 64 (FIG. 3). ) Is set in the special figure buffer (S81), and the second special figure jackpot determination process is completed.

On the other hand, when it is determined in S82 that the game control microcomputer 61 is not a small hit (S82: No), the special symbol stop symbol data for confirming and displaying the lost symbol of the special symbol is set in the special symbol buffer (S82: No). S81), the second special figure jackpot determination process is completed.

Further, when the game control microcomputer 61 determines that the probability change flag is ON in S77, that is, the current game state is a high probability state (S77: Yes), the high hit determination table Ta1 is high. With reference to the jackpot random number in the probability state, it is determined whether or not there is the same random number as the jackpot random number read in S75, that is, whether or not the jackpot is a jackpot (S84). For example, when the jackpot random number read in S75 is "600", it is determined as a jackpot because "600" exists in the jackpot random numbers 0 to 649 in the high probability state in the jackpot determination table Ta1 ( S84: Yes). Subsequently, the game control microcomputer 61 determines the type of jackpot (S79), turns on the jackpot flag (S80), sets the special figure stop symbol data in the special figure buffer (S81), and sets the special figure stop symbol data in the special figure buffer (S81). Finish the jackpot judgment process.

Further, in S84, when it is determined that the hit is not a big hit (S84: No), the hit / fail determination of whether or not it is a small hit is performed (S85). For example, when the jackpot random number read in S75 is "880", it is determined as a small hit because "880" exists in the jackpot random numbers 650 to 65919 in the high probability state in the jackpot determination table Ta1. (S85: Yes). Subsequently, the game control microcomputer 61 turns on the small hit flag (S83), sets the special figure stop symbol data in the special figure buffer (S81), and finishes the second special figure big hit determination process.

(2nd special figure fluctuation pattern selection process (1st special figure fluctuation pattern selection process))

I will explain while doing it. Since the second special figure variation pattern selection process (S62 in FIG. 21) and the first special figure variation pattern selection process (S68 in FIG. 21) have the same processing flow, they will be described together. Further, when a matter common to the first special figure holding storage unit 64a and the second special figure holding storage unit 64b is explained, it is simply referred to as a special figure holding storage unit.

Here, if it is determined that the process has not ended (S110: No), the special symbol variation process ends. As a result, the variable display of the special symbol is continued. On the other hand, when it is determined that the process has ended (S110: Yes), a fluctuation stop command for stopping the fluctuation display of the special symbol is set in the command buffer provided in the RAM 64 (FIG. 3) (S111). Subsequently, the game control microcomputer 61 responds to the special symbol stop symbol data set in S81 (FIG. 22) of the second special symbol jackpot determination process (first special symbol jackpot determination process) by displaying the variation of the special symbol. The special symbol stop process of stopping at the symbol (the jackpot symbol of the special symbol or the lost symbol of the special symbol) is executed (S112).

Subsequently, the game control microcomputer 61 executes the game state management process (S113). In this game state management process, for example, in the ST machine, it is determined whether or not the probability change flag is ON, and if it is determined that it is ON, the number of changes of the special symbol in the high probability state is subtracted. The value of the probability variation counter to be counted is subtracted by 1, and it is determined whether or not the value of the probability variation counter is "0". Then, when it is determined that it is "0", the probability change flag is turned off. On the other hand, if it is not an ST machine, the probability change flag is not changed depending on the number of fluctuations. Subsequently, it is determined whether or not the time saving flag is ON, and if it is determined that it is ON, the value of the time saving counter that counts the number of fluctuations of the special symbol in the time saving state by the subtraction method is subtracted by 1. , It is determined whether or not the value of the time reduction counter is "0".

The game control microcomputer 61 sets the game state designation command including the information of each flag in the output buffer of the RAM 64, and finishes the game state management process. The game state designation command set in the output buffer of the RAM 64 is output to the sub control board 100 in the output process of the main timer interrupt process (S10 in FIG. 18).

Subsequently, the game control microcomputer 61 determines whether or not the jackpot flag is ON (S114), and if it is determined that the jackpot flag is ON (S114: Yes), executes the game state reset process. (S115). In this game state reset process, it is determined whether or not the probability change flag is ON, and if it is determined that the probability change flag is ON, the probability change flag is turned OFF. Further, it is determined whether or not the time saving flag is ON, and if it is determined that the time saving flag is ON, the time saving flag is turned OFF. That is, during the execution of the jackpot game, it is controlled to the normal probability state and the non-time saving state.
Subsequently, the game control microcomputer 61 sets the jackpot opening setting (S116) in order to start the jackpot game, and sets the opening command for executing the jackpot opening (S117). The jackpot opening is an effect of displaying an effect image celebrating the occurrence of a big hit on the effect display device 7 or playing a music celebrating the occurrence of a big hit from each speaker 8. In the opening setting, the execution time of the opening of the jackpot game is set to a predetermined timer.
Subsequently, the game control microcomputer 61 sets the value of the special electric service operation effective counter (S118), and ends the special symbol variation processing. The special electric service operation effective counter is a counter that counts the remaining number of rounds in the jackpot game. After that, the jackpot game is started based on the set opening setting and the counter value.

Further, when it is determined in S114 that the jackpot flag is not ON (S114: No), it is determined whether or not the small hit flag is ON (S119), and it is determined that it is ON. (S119: Yes) executes the large winning opening opening process (S120). In this large winning opening opening process, the first large winning opening 32 is opened, and the first large winning opening 32 is in a state of being opened until a predetermined number (for example, 5) of game balls are entered or a predetermined time elapses. .. In particular, in the small hit rush state, the small hit is won with an extremely high probability in the lottery shown in FIG. It becomes possible to gradually increase the number of game balls. On the other hand, when it is determined that the small hit flag is not ON (S119: No), this special symbol variation process is completed.
