Description

  The present invention is provided in a game area, a change symbol display means for displaying a change symbol on the change symbol display section, a normal symbol display means for displaying a normal symbol on the normal symbol display section, and a game area. Special winning device having a game ball detecting means, a start winning opening, a normal electric accessory that can be changed between a state where the game ball is easy to win and a state where it is difficult to win, and a large winning opening that is normally closed. And a pachinko machine in which the variation symbol varies based on the winning information to the starting port in the normal gaming state and the regular symbol varies based on the game ball detection information of the game ball detection means.

Conventionally, a variation symbol display means that is provided in a game area and displays a variation symbol on the variation symbol display portion, a normal symbol display means that displays a normal symbol on the normal symbol display portion, and a game disposed in this game region A special winning device having a ball detecting means, a start winning opening, a normal electric accessory that can be changed between a state where a game ball is easy to win and a state where it is difficult to win, and a large winning opening that can be opened and closed normally. Various types of pachinko machines have been proposed in which the variation symbol fluctuates based on the winning information at the starting port in the normal gaming state and the normal symbol varies based on the game ball detection information of the game ball detection means. .
For example, a special symbol display device capable of variably displaying a plurality of symbols in a game part in which a hit ball launched by a player flows down, and a starting means for creating a condition for starting variable display of the special symbol display device, A variable winning device that can be converted into a first state that is disadvantageous to the player and a second state that is advantageous to the player by establishing a specific condition based on the combination of display symbols when the special symbol display device stops variable display. And a pachinko machine having at least a continuation means for creating a condition for maintaining the second state of the variable winning device, and having a control means for controlling each of the devices, a plurality of symbols are provided in the game unit. A starter that creates a condition for starting variable display of the special symbol display device by arranging a variable symbol display normal symbol display device and display start means for starting variable display of the normal symbol display device Is constituted by a normal electric accessory that can be converted into a first state that is disadvantageous to the player and a second state that is advantageous to the player based on the display symbol displayed when the normal symbol display device stops variable display. The display start means is constituted by a detection switch facing a normal electric accessory, and when the combination of symbols displayed by the special symbol display device becomes a predetermined mode, the special symbol display device and the normal symbol display are displayed. There has been proposed a pachinko machine that is configured to change the fluctuation time required for the apparatus to stop variable display (see, for example, Patent Document 1).

According to such a pachinko machine, when the combination of the symbols to be visually displayed is a predetermined combination, the variable winning device (big prize opening) is opened, and the combination of symbols is a specific symbol, for example, “777”. In this case, by reducing the fluctuation time of the symbol displayed by the normal symbol display device and the special symbol display device, the probability of being a big hit from the combination of symbols has not changed, but the big hit per unit time has not changed Probability increases. Therefore, it is possible to generate big hits in a short period of time, increasing the expectation that the big hits will be generated continuously, and to make an entertaining pachinko game.
JP-A-5-177045 (paragraphs (0006) to (0093), FIGS. 1 to 17)

However, in the conventional pachinko machine described above, there are only two types of pachinko games in the normal game state when the variation time of the symbols displayed by the normal symbol display device and the special symbol display device is long and short. Since the jackpot game is only given, there is a problem that it is difficult to give diversity to the pachinko game and further increase the interest of the player.
On the other hand, when diversity is given to the pachinko game, there is a problem that it is difficult to accurately control the probability of occurrence of jackpots and the like, and it is difficult to achieve a profit balance between the player and the game store.

  Accordingly, the present invention has been made to solve the above-described problems, and by providing a plurality of types of jackpot games that are given when a floating symbol stops at a jackpot symbol, a new variety is added to the pachinko game. It is an object of the present invention to provide a pachinko machine capable of further increasing the interest of a player by giving a bonus. In addition, by providing a plurality of types of jackpot games, even if diversity is given to the pachinko game, the probability of occurrence of jackpots can be accurately controlled, and the profit balance between the player and the game store can be easily achieved. The purpose is to provide a pachinko machine.

In order to achieve the above object, the pachinko machine according to claim 1 is provided with a variation symbol display means provided in the game area for displaying a variation symbol on the variation symbol display portion, and a normal symbol display for displaying a regular symbol on the normal symbol display portion. Means, a game ball detecting means disposed in the game area, a start winning opening, a normal electric accessory that can be changed between a state where the game ball is easy to win and a state where it is difficult to win, and is normally closed. A special winning device having a large winning opening that can be opened and closed, the normal symbol fluctuates based on the gaming ball detection information of the gaming ball detection means, and in the normal gaming state, the winning information to the starting port In the pachinko machine in which the variation symbol fluctuates based on, a jackpot determination means for determining whether or not a jackpot has been drawn based on the winning of the game ball to the start opening, and for the winning of the game ball to the normal electric accessory Base A normal winning judgment means for determining whether or not the normal winning is drawn, and when the normal winning judgment means determines that the normal winning is drawn, and after the normal symbol fluctuates, it stops at a predetermined normal winning symbol Includes a bonus game granting means for granting a bonus game state in which a game ball is likely to win a prize to the ordinary electric accessory, and a jackpot symbol belonging to a predetermined first jackpot symbol group among a plurality of types of jackpot symbols Alternatively, it is determined that a jackpot symbol selection means for drawing one of the jackpot symbols belonging to the predetermined second jackpot symbol group with a predetermined first lottery probability, and that the jackpot determination means has been selected by the jackpot determination means, After the variable symbol has changed, if the jackpot symbol belonging to the first jackpot symbol group is stopped, there are a plurality of the big prize winning openings. The game is controlled to be in the first special game state where the game ball can be easily won from the big winning opening, and after the first special game state, the variable symbol is stopped at one of the jackpot symbols. Until the bonus game state is given with a predetermined second lottery probability, and the jackpot determining means determines that the jackpot is lottery, and the variation symbol is changed. In the case of stopping at the jackpot symbol belonging to the second jackpot symbol group, the opening of the big prize opening which is shorter than the opening time of the big prize opening in the first special game state is the first special game. After the number of times that the number of the big prize opening can be released is less than the number of times that can be opened, the special prize opening is controlled so as to enter the second special gaming state, and after the second special gaming state ends , A second special game control means for the variation pattern is controlled so as to impart a high predetermined third lottery probability than the second lottery probability granting of the privilege game state until it stops at either the jackpot symbol, the The normal game state is determined by a predetermined fourth lottery probability after the first special game state or the second special game state is finished, and the first special game state or the second special game state is given. A first normal game mode, and a second normal game mode for drawing the first special game state or the second special game state with a predetermined fifth lottery probability higher than the fourth lottery probability, After the end of the first special game state or the second special game state, the normal game state in which either the first normal game mode or the second normal game mode is drawn with a predetermined sixth lottery probability Includes game mode setting means It is characterized by that.

  In the pachinko machine according to claim 1, the normal winning lottery is drawn based on the game ball detection information of the game ball detection means, and the normal symbol displayed on the normal symbol display part of the normal symbol display means is changed to a predetermined normal When the winning symbol is stopped, a special gaming state is given to the ordinary electric accessory so that a game ball can easily win a prize. Further, in the normal game state until the first special game state or the second special game state to be described later is given, it is determined that the jackpot has been drawn based on the winning information at the starting port, and the fluctuation of the fluctuation symbol display means If the symbol displayed on the symbol display section changes and then stops at the jackpot symbol belonging to the predetermined first jackpot symbol group that is drawn at the predetermined first lottery probability, the big prize opening can be opened multiple times. The first special gaming state in which a game ball can be easily won from the big winning opening is given, and after the first special gaming state is finished, the normal electric combination is performed until the variable symbol stops at one of the jackpot symbols. A privileged gaming state in which a game ball is likely to win a game is drawn and given with a predetermined second lottery probability. Further, in this normal gaming state, it is determined that the jackpot has been drawn based on the winning information at the starting gate, and after the variation symbol displayed on the variation symbol display unit of the variation symbol display means has changed, the predetermined first lottery In the case of stopping at a jackpot symbol belonging to a predetermined second jackpot symbol group drawn by probability, the opening of the big prize opening shorter than the opening time of the big prize opening in the first special gaming state is After being played a plurality of times less than or equal to the number of times the grand prize opening in the first special gaming state is opened, a second special gaming state in which the big prize opening is closed is given, and after the end of the second special gaming state Until the fluctuation symbol stops at one of the jackpot symbols, the bonus game state in which the game ball is likely to win a normal electric game is given at a predetermined third lottery probability higher than the second lottery probability. A lottery will be given.

Thereby, when the jackpot is lottery based on the winning information to the start opening, after the variation symbol is fluctuated, when it stops at the jackpot symbol belonging to the predetermined first jackpot symbol group of the plurality of types of jackpot symbol, The first special gaming state is awarded when the first special gaming state that allows the big winning opening to be opened multiple times is given, and after the fluctuation symbol is changed, the game is stopped at the big winning symbol belonging to the predetermined second big winning symbol group After the opening of the grand prize opening, which is shorter than the opening time of the special prize opening at the time of the game, is performed a plurality of times less than or equal to the number of times of opening of the big prize opening in the first special gaming state, A second special game state to be closed is given. Therefore, when the jackpot is lottery and the first special gaming state is given, the big winning opening is opened, and the game balls are easily won from the big winning opening, so that the player can It becomes possible to easily acquire a prize ball. On the other hand, when the second special game state is given, even if the big prize opening is opened several times, the opening time of the big prize opening is shorter than the first special gaming state, and the number of times the big prize opening is opened However, since the number of times the first special game state is released is less than, the number of award balls that can be acquired is greatly reduced as compared to the first special game state. Therefore, the player's expectation for the acquisition of the first special gaming state can be increased, and the interest can be increased.
In addition, when the second special game state is given, after the second special game state is finished, the game ball is likely to win a normal electric accessory until the variable symbol stops at one of the jackpot symbols. The award gaming state to be given is drawn with a predetermined third lottery probability higher than the second lottery probability after the end of the first special gaming state. The number of winning game balls will be higher than usual, and even if a player plays a pachinko game for a long time, it will be easy to prevent a decrease in game balls, and it will be possible to continue the pachinko game for a long time. By continuing, it becomes possible to increase the number of winning balls. In addition, after the end of the second special game state, it is possible to easily prevent a decrease in game balls, so that the player's expectation for the acquisition of the first special game state can be maintained for a long time. Can be increased.

In addition, every time a jackpot is drawn based on a winning at the start opening, the first special gaming state or the second special gaming state is drawn with the first lottery probability, and after the first special gaming state is finished, the variable symbol Until the game is stopped with one of the jackpot symbols, the bonus game state is drawn and given with a predetermined second lottery probability, and after the second special game state is over, the variable symbol is one of the jackpot symbols. Until the game is stopped, the bonus game state is drawn and given with a predetermined third lottery probability higher than the second lottery probability. As a result, each time a jackpot is drawn based on winning at the start opening, a game mode that allows a lot of prize balls to be obtained in a short time and a lot of prize balls by continuing the game for a long time Since one game mode is selected and set from two game modes that can be played, it is possible to diversify the pachinko game and increase the interest of the player. Can attract.
Furthermore, by changing the predetermined first lottery probability, it is possible to accurately control the lottery probability of granting the privilege gaming state set after the end of the first special gaming state or the second special gaming state, By changing the second lottery probability and the third lottery probability, respectively, the lottery probability for granting the privilege gaming state can be accurately controlled, so that the profit balance between the player and the game shop can be easily achieved. .
In addition, in the second special game state, it is preferable that the opening time of the big winning opening is a short time in which it is difficult to win a game ball. In the case of the second special game state, the short-time opening in which it is difficult to win the game ball to the big prize opening is performed a plurality of times with a smaller number of times than the number of times of the big prize opening in the first special gaming state. Is preferred. As a result, in the second special game state, it becomes difficult to win game balls to the big prize opening, and it is thus difficult for the player to acquire a lot of prize balls in a short time.

Furthermore, the normal gaming state includes a first normal gaming mode in which a jackpot grant is drawn with a predetermined fourth lottery probability after the end of the first special gaming state or the second special gaming state, A second normal game mode that is given with a predetermined fifth lottery probability higher than the four lottery probabilities, and either the first normal game mode or the second normal game mode is drawn with a predetermined sixth lottery probability. .
As a result, when the second normal game mode is set as the normal game state, the probability of winning the jackpot is increased, so that the player's sense of expectation for acquiring the second normal game mode can be increased, Can be strongly attracted to pachinko games. In addition, since either the first normal game mode or the second normal game mode is drawn and given with a predetermined sixth lottery probability, the player's sense of expectation for acquiring the second normal game mode can be enhanced. , Can increase interest. Also, when the second normal gaming state is granted after the end of the second special gaming state, there is a high possibility that the first special gaming state will be given in a short time, and the player prevents a decrease in game balls. In addition, since it becomes possible to acquire many prize balls in a short time, the pachinko game can be further diversified.

A big hit counter 463A to be stored is provided. The count value of the jackpot counter 463A is read at the timing when the switch signal is output from the start port switch, and it is determined whether or not the jackpot is based on the read count value. Here, for example, as described later, when the jackpot lottery mode is the normal mode (see FIGS. 7 and 8), the count value “7” corresponds to the jackpot, and the jackpot lottery mode is the probability change mode (see FIGS. 7 and 8). 8), the count values “1, 3, 5, 7” correspond to the jackpot, and the other count values are lost.

In addition, a normal symbol counter 463B is provided in which a numerical value obtained by repeatedly adding one by one from 0 to 9 (returning to the minimum value 0 next to the maximum value 9) based on the clock signal input from the clock circuit 460 is provided. Yes. The count value of the normal symbol counter 463B is read at the timing when the switch signal is input from each gate switch, and it is determined whether or not it is a hit based on the read count value. Here, for example, as described later, when the normal winning lottery mode is the normal mode (see FIGS. 7 and 8), the count value “1” corresponds to the normal winning, and the normal winning lottery mode is the special mode (SP Mode) (see FIGS. 7 and 8), the count values “5, 6, 7, 8, 9” correspond to normal hits, and the other count values are normally lost.
In addition, a first holding counter 463C is provided that counts up to a maximum of four winning prizes in the starting port 31 while the changing symbol of the special symbol display device 18 is changing. Further, a second holding counter 463D is provided that counts up to four passes through the gate 23 while the normal symbol of the normal symbol display unit 20 is changing.

Is provided. The reach value of the reach counter 463E is read at the timing when the switch signal is input from the start port switch because the reach state does not occur unless the pachinko ball wins the start port 31, and based on the read count value. It is determined whether or not reach is reached. Here, for example, this corresponds to a case where the count value “0 to 27” is out of reach after reaching, and the case where the count value “28 to 142” is out immediately without reaching reach.

The RAM 463 stores a jackpot symbol selection counter in which a numerical value obtained by repeatedly adding 1 from 0 to 159 based on the clock signal output from the clock circuit 460 (returns to the minimum value 0 next to the maximum value 159) is stored. 463F is provided. The count value of the jackpot symbol selection counter 463F is read at the timing when the switch signal is output from the start port switch, and the jackpot symbol displayed on the special symbol display device 18 based on the read count value is as described below. Are selected from the first game mode selection table 71 (see FIG. 7) and the second game mode selection table 72 (see FIG. 8). Here, there are eight types of jackpot symbols: “111”, “123”, “222”, “341”, “333”, “234”, “444”, “412” (see FIGS. 7 and 8). As will be described later, any one of “111”, “123” to “412” is selected and displayed on the liquid crystal display 19 at the time of the big hit (see FIG. 12).
As is known, each jackpot symbol is a symbol that is stopped and displayed after a series of symbol variations based on various display effects at the time of jackpot.

  The RAM 463 stores a normal symbol selection counter in which a numerical value obtained by repeatedly adding 1 from 0 to 3 based on the clock signal output from the clock circuit 460 (returns to the minimum value 0 after the maximum value 3) is stored. 463G is provided. Here, for example, in the case of normal winning, the count value “0, 1” corresponds to the normal symbol “11”, and the count value “2, 3” corresponds to the normal symbol “77”. In the case of normal loss, the count value “0, 1” corresponds to the normal symbol “17”, and the count value “2, 3” corresponds to the normal symbol “71”. Each ordinary symbol is a symbol that is stopped and displayed after a series of symbol fluctuations, as is well known.

  The RAM 463 stores a variation pattern selection counter that stores a numerical value obtained by repeatedly adding one by one from 0 to 9 based on the clock signal output from the clock circuit 460 (the maximum value 9 then returns to the minimum value 0). 463H is provided. As is well known, each variation display pattern is a pattern for displaying a series of symbol variations based on various display effects. In this embodiment, the display effect time is “10 seconds” as the reach loss display pattern. , “20 seconds” and “30 seconds” are set. Also, two types of jackpot display patterns of “22 seconds” and “32 seconds” are set.

In addition, the RAM 463 stores a numerical value obtained by repeatedly adding 1 from 0 to 200 based on the clock signal output from the clock circuit 460 (the maximum value 200 then returns to the minimum value 0). 463I is provided.
In addition, the RAM 463 stores a numerical value obtained by repeatedly adding 1 from 0 to 143 based on the clock signal output from the clock circuit 460 (the maximum value 143 then returns to the minimum value 0). 463J is provided.

Thereafter, in S4, the CPU 461 executes the sub-process of the jackpot game process, then executes the sub-process of the normal symbol variation process in S5, and executes the sub-process of the normal hit game process in S6. finish.

Next, the sub-process of the start opening winning process (S1) will be described with reference to FIG.
As shown in FIG. 10, first, in S 11, the CPU 461 receives a pachinko ball winning signal from the start port 31, that is, a pachinko ball detection signal from the start port switch is input via an input / output circuit (I / O) 464. A determination process is performed to determine whether or not it has been performed.
If the pachinko ball detection signal from the start port switch is not input via the input / output circuit 464 (S11: NO), the sub-process is terminated and the process returns to the main flowchart.

On the other hand, when a pachinko ball detection signal from the start port switch is input via the input / output circuit 464 (S11: YES), the sub-process is executed after executing the “count value acquisition process” in S12. End and return to the main flowchart.
In this “count value acquisition process”, the CPU 461 substitutes the numerical value stored in the big hit counter 463A when the pachinko ball detection signal is input from the start port switch as the “big hit count value” in the algebra V. Is stored in the parameter storage area 463K. Therefore, any numerical value of “0” to “299” is assigned to the algebra V and stored in the parameter storage area 463K.

At the same time, the CPU 461 substitutes the numerical value stored in the reach counter 463E when the winning signal is input from the start port switch into the algebra M as the “reach count value” at that time, and stores it in the parameter storage area 463K. To do. Therefore, any numerical value of “0” to “142” is assigned to the algebra M and stored in the parameter storage area 463K.
At the same time, the CPU 461 substitutes the numerical value stored in the jackpot symbol selection counter 463F when the winning signal is input from the start port switch into the algebra Y as the “hit symbol selection count value” at that time, and stores the parameter. Store in area 463K. Therefore, any numerical value of “0” to “159” is substituted for this algebra Y and stored in the parameter storage area 463K.

At the same time, the CPU 461 substitutes the numerical value stored in the variation pattern selection counter 463H when the winning signal is input from the start port switch into the algebra H as the “variation pattern selection count value” at that time, and stores the parameter. Store in area 463K. Accordingly, this algebra H is assigned with any numerical value “0” to “9” and stored in the parameter storage area 463K.
At the same time, the CPU 461 substitutes the numerical value stored in the lost symbol selection counter 463I when the winning signal is input from the start port switch into the algebra I as the “lost symbol selection count value” at that time, and stores the parameter. Store in area 463K. Therefore, any numerical value of “0” to “200” is assigned to the algebra I and stored in the parameter storage area 463K.

At the same time, the CPU 461 substitutes the numerical value stored in the reach symbol selection counter 463J when the winning signal is input from the start port switch into the algebra F as the “reach symbol selection count value” at that time, and stores the parameter. Store in area 463K. Therefore, any numerical value of “0” to “143” is substituted for this algebra F and stored in the parameter storage area 463K.
The above-mentioned count values at the time of winning each pachinko ball won at the start port 31 during the change of the changing pattern displayed on the liquid crystal display 19 are stored in the parameter storage area 463K, and the processing after S2 described later is sequentially performed. Is executed.

Next, the sub-process of the jackpot determination process (S2) will be described with reference to FIG.
As shown in FIG. 11, first, in S21, the CPU 461 executes a jackpot value acquisition process.
In the jackpot value acquisition process, first, the CPU 461 reads the probability variation flag stored in the RAM 463. If the probability variation flag read from the RAM 463 is ON, that is, “1”, it is determined that the probability variation mode is set, and the “probability large hit value” stored in the ROM 462 in advance (in this embodiment). Are “1”, “3”, “5”, and “7”), and this “probable variation jackpot value” is stored as “jackpot value” in the parameter storage area 463K. On the other hand, when the probability variation flag read from the RAM 463 is OFF, that is, “0”, it is determined that the normal mode is set, and the “normal jackpot value” stored in the ROM 462 in advance (in the case of this embodiment). Is “7”), and this “ordinary jackpot value” is stored in the parameter storage area 463K as a “jackpot value”.

Subsequently, in S <b> 22, the CPU 461 executes a determination process for determining whether or not it is “big hit”.
In the determination process of whether or not this is a “big hit”, first, the algebra V as the “big hit count value” is read from the parameter storage area 463K. Then, it is determined whether or not the algebra V matches any of the “big hit values” stored in the parameter storage area 463K. If they match, the jackpot algebra R (“0” is substituted for the jackpot algebra R when the power is turned on) is stored in the parameter storage area 463K by substituting “1”. Then, “0” is substituted into the jackpot algebra R and stored in the parameter storage area 463K.
Accordingly, in the normal mode gaming state, the occurrence probability of “big hit” is 1/300 (fourth lottery probability). Further, in the gaming state in the probability variation mode, the occurrence probability of “big hit” is 4/300 (the fifth lottery probability). As a result, in the probability variation mode, the probability of being a “hit” is about four times that in the normal mode gaming state.
In the normal mode gaming state, the variation symbol variation time is about 10 seconds to 30 seconds. In the probability variation mode gaming state, the variation symbol variation time is about 5 seconds to 7 seconds. You may make it stop as a second earlier than the game mode of a normal mode.

Then, the jackpot algebra R is read again from the parameter storage area 463K, and it is determined whether the jackpot algebra R is “0” or “1”. That is, it is determined whether or not “big hit” has occurred.
When the jackpot algebra R is “1”, it is determined that “big jackpot” has occurred (S22: YES), and in S23, the CPU 461 calculates the algebra Y as the jackpot symbol selection count value from the parameter storage area 463K. The algebra Y is read as the “count value” of the first game mode selection table 71 or the second game mode selection table 72 stored in the selection table storage area 463L, and “ The jackpot symbol is selected and stored as a jackpot symbol in the parameter storage area 463K of the RAM 463.
For example, when the algebra Y read from the parameter storage area 463K is “25” and the selection table stored in the selection table storage area 463L is the first game mode selection table 71, “123” is the RAM 463 as the jackpot symbol. Is stored in the parameter storage area 463K. Further, when the algebra Y read from the parameter storage area 463K is “25” and the selection table stored in the selection table storage area 463L is the second game mode selection table 72, “111” as the jackpot symbol is the RAM 463. Is stored in the parameter storage area 463K.

In S24, the CPU 461 executes a determination process for determining whether or not the normal game state in the “probability change mode” has been acquired as the normal game state after the end of the first jackpot game or the second jackpot game.
In the process of determining whether or not the normal gaming state of the “probability change mode” has been acquired, first, the CPU 461 reads the algebra Y as the jackpot symbol selection count value from the parameter storage area 463K, and stores the algebra Y in the selection table. The “count value” in either the first game mode selection table 71 or the second game mode selection table 72 stored in the area 463L is selected, and the “big hit lottery mode” corresponding to the “count value” is selected. In the case of “probability change mode”, it is determined that the normal gaming state of “probability change mode” has been acquired. On the other hand, when the “big hit lottery mode” corresponding to the “count value” is selected and the “normal mode” is selected, it is determined that the normal gaming state of the “probability change mode” has not been acquired. Accordingly, when the first game mode selection table 71 is stored in the selection table storage area 463L, the “probability change mode” is drawn with a lottery probability (sixth lottery probability) of 4/8. In addition, when the second game mode selection table 72 is stored in the selection table storage area 463L, the “probability change mode” is drawn with a 2/4 lottery probability (sixth lottery probability).

If it is determined that the normal game state of the “probability change mode” is acquired as the normal game state after the end of the first jackpot game or the second jackpot game (S24: YES), in S25, the CPU 461 stores the parameters. The probability variation flag is read from the area 463K, and this probability variation flag is turned ON. In other words, “1” is substituted into this probability change flag and stored again in the parameter storage area 463K.
On the other hand, when the normal game state of the “normal mode” is acquired as the normal game state after the end of the first jackpot game or the second jackpot game (S24: NO), in S26, the CPU 461 reads from the parameter storage area 463K. The probability variation flag is read and this probability variation flag is turned OFF. That is, “0” is substituted for the probability variation flag and stored again in the parameter storage area 463K. At the time of activation, “0” is assigned to the probability variation flag and stored in the parameter storage area 463K.

Subsequently, in S27, the CPU 461 executes determination processing for determining whether or not to execute the second jackpot game as the jackpot game.
In the process of determining whether or not to execute the second jackpot game as the jackpot game, first, the CPU 461 reads the algebra Y as the jackpot symbol selection count value from the parameter storage area 463K, and the algebra Y is selected in the selection table storage area. The “count value” in either the first game mode selection table 71 or the second game mode selection table 72 stored in 463L is selected, and the “big hit game mode” corresponding to the “count value” is selected, In the case of “2 jackpot game”, it is determined that the second jackpot game is executed as the jackpot game. On the other hand, when the “big hit game mode” corresponding to the “count value” is selected and the “first big hit game” is selected, the second big hit game is not executed as the big hit game, that is, the first big hit game is executed. Judge that.
Here, in the case where the first game mode selection table 71 is stored in the selection table storage area 463L, the “hit symbols” corresponding to the “second jackpot game” are “123”, “341”, “234”. ”Or“ 412 ”is selected, and the“ hit symbol ”corresponding to“ first jackpot game ”is any of“ 111 ”,“ 222 ”,“ 333 ”, and“ 444 ”. Selected (first lottery probability). Further, when the second game mode selection table 72 is stored in the selection table storage area 463L, the “big hit symbol” corresponding to the “second big hit game” is either “123” or “341”. Is selected, and either “333” or “444” is selected as the “hit symbol” corresponding to “first jackpot game” (first lottery probability).

If it is determined that the second jackpot game is to be executed as a jackpot game (S27: YES), in S28, the CPU 461 reads the jackpot game flag from the parameter storage area 463K and turns this jackpot game flag ON. That is, “1” is substituted for the jackpot game flag and stored again in the parameter storage area 463K.
On the other hand, when it is determined that the second jackpot game is not executed as the jackpot game, that is, the first jackpot game is executed (S27: NO), the jackpot game flag is read from the parameter storage area 463K in S29, and this jackpot game is played. Turn off the flag. That is, “0” is substituted for the jackpot game flag and stored again in the parameter storage area 463K.

In S30, the CPU 461 executes determination processing for determining whether or not the “special mode (SP mode)” has been acquired as the normal winning lottery mode after the end of the first jackpot game or the second jackpot game.
In the process of determining whether or not the normal special lottery mode of the “special mode (SP mode)” has been acquired, the CPU 461 first reads the algebra Y as the jackpot symbol selection count value from the parameter storage area 463K, and the algebra. Y is the “count value” in either the first game mode selection table 71 or the second game mode selection table 72 stored in the selection table storage area 463L, and the “normal lottery mode” corresponding to the “count value” In the case of “special mode (SP mode)”, it is determined that the normal lottery mode of “special mode (SP mode)” has been acquired. On the other hand, if the “normal winning lottery mode” corresponding to the “count value” is selected and the “normal mode” is selected, it is determined that the normal winning lottery mode of the “special mode (SP mode)” has not been acquired. .

When it is determined that the “special mode (SP mode)” is acquired as the normal winning lottery mode after the end of the first jackpot game or the second jackpot game (S30: YES), in S31, the CPU 461 causes the game to The second game mode selection table 72 is read from the mode selection table storage area 462A and stored in the selection table storage area 463L. Subsequently, in S32, the CPU 461 reads the normal symbol flag from the parameter storage area 463K, and turns this normal symbol flag ON. That is, “1” is assigned to the normal symbol flag and stored again in the parameter storage area 463K, and then the sub-process is terminated and the process returns to the main flowchart.
On the other hand, if it is determined that the “special mode (SP mode)” has not been acquired as the normal winning lottery mode after the end of the first jackpot game or the second jackpot game (S30: NO), the CPU 461 in S33, The first game mode selection table 71 is read from the game mode selection table storage area 462A and stored in the selection table storage area 463L. Subsequently, in S34, the CPU 461 reads the normal symbol flag from the parameter storage area 463K, and turns off this normal symbol flag. That is, “0” is substituted for the normal symbol flag and stored again in the parameter storage area 463K. Then, the sub-process is terminated and the process returns to the main flowchart. At the time of activation, “0” is assigned to the normal symbol flag and stored in the parameter storage area 463K.

In S22, when the read jackpot algebra R is “0”, it is determined as a loss (S22: NO), and in S35, the CPU 461 displays the three variations of the variation symbol at this time. Among the symbols, the reach state where two symbols are aligned (for example, “5, -5”, “7,-, 7”, etc., where “-” means that the symbol is rotating) is displayed. It is determined whether or not to display a loss later (for example, “5, 4, 5”, “7, 3, 7”, etc.).
In this determination, the algebra M as the reach count value stored in the parameter storage area 463K is read, and the reach generation value stored in advance in the ROM 462 (in this embodiment, “0” to “27”). .)), It is determined that the losing is displayed after the reach state (S35: YES), and a losing reach symbol is selected in S36. The selection of the lose reach symbol is performed by reading the algebra F as the reach symbol selection count value from the parameter storage area 463K, reading out the reach lose symbol corresponding to the algebra F from the ROM 462, and as a reach lose symbol for instructing the CPU 661 of the display control board 66. After storing in the parameter storage area 463K, the sub-process is terminated and the process returns to the main flowchart.

  In the “complete lose table” (not shown), the display effect time is set to three types of display effect times of “10 seconds”, “20 seconds”, and “30 seconds” as a variation pattern of complete loss. ing. In addition, in the “reach A lose table” (not shown), a display pattern having a display effect time of “20 seconds” is set as a display pattern for reach lose as a variation pattern. In addition, in the “reach B loss table” (not shown), a display pattern having a display effect time of “30 seconds” is set as a display pattern of reach loss as a variation pattern. In addition, in the “reach C lose table” (not shown), a display pattern having a display effect time of “10 seconds” is set as a reach loss display pattern as a variation pattern. Further, in the “reach A probability variation hit table” and “reach A normal hit table” (not shown), a variation effect pattern having a display effect time of “22 seconds” is set as a jackpot display pattern. Further, in the “reach B probability variation table” and “reach B normal variation table” (not shown), a variation effect pattern having a display effect time of “32 seconds” is set as a jackpot display pattern.

  In S41, the variation pattern lottery process executed by the CPU 461 of the main board 46 first reads the jackpot algebra R from the parameter storage area 463K. If the jackpot algebra R is “1”, a “jackpot” is generated. It is determined that the probability variation flag is read from the RAM 463, and when the probability variation flag is ON, it is determined that it is a big hit in the probability variation mode. Then, the algebra H as the variation pattern selection count value is read from the parameter storage area 463K, and when this algebra H is an even number, “pattern 5” is stored in the parameter storage area 463K as the variation pattern instructed to the CPU 661 of the display control board 66. On the other hand, if the algebra H is an odd number, “pattern 6” is stored in the parameter storage area 463K as a variation pattern instructed to the CPU 661 of the display control board 66.

  Also, the jackpot algebra R is read from the parameter storage area 463K, and when the jackpot algebra R is “1”, it is determined that the “jackpot” has occurred, the probability variation flag is read from the RAM 463, and the probability variation flag is OFF. In this case, it is determined that the normal mode is a big hit. Then, the algebra H as the variation pattern selection count value is read from the parameter storage area 463K, and when this algebra H is an even number, “pattern 7” as the variation pattern instructed to the CPU 661 of the display control board 66 is stored in the parameter storage area 463K. On the other hand, if the algebra H is an odd number, “pattern 8” is stored in the parameter storage area 463K as a variation pattern instructed to the CPU 661 of the display control board 66.

  Further, the CPU 461 reads the jackpot algebra R from the parameter storage area 463K, and when the jackpot algebra R is “0”, it is determined that “losing” has occurred, and is stored again in the parameter storage area 463K. The algebra M as the reach count value is read out, and it is determined whether or not it coincides with any of the reach occurrence numerical values (in the present embodiment, “0” to “27”) stored in the ROM 462 in advance. If the CPU 461 matches any of the values, the algebra H as the variation pattern selection count value is read from the parameter storage area 463K. If the algebra H is “0 to 2”, the CPU 661 of the display control board 66 is instructed. “Pattern 2” is stored in the parameter storage area 463K as the variation pattern. When the algebra H is “3 to 6”, “pattern 3” is stored in the parameter storage area 463K as a variation pattern instructed to the CPU 661 of the display control board 66. Further, when the algebra H is “7 to 9”, “pattern 4” is stored in the parameter storage area 463K as a variation pattern instructed to the CPU 661 of the display control board 66.

  On the other hand, the CPU 461 reads the jackpot algebra R from the parameter storage area 463K. If the jackpot algebra R is “0”, the CPU 461 determines that “losing” has occurred and stores it again in the parameter storage area 463K. When the algebra M as a reach count value is read and does not coincide with any of the reach generation values stored in the ROM 462 in advance, “pattern 1” is set as a parameter as a variation pattern instructed to the CPU 661 of the display control board 66. Store in the storage area 463K.

Thereafter, in S42, the CPU 461 again reads the final stop symbol data and the variation pattern instructed to the CPU 661 of the display control board 66 from the parameter storage area 463K, and outputs these information data to the CPU 661 of the display control board 66.
In S43, the CPU 461 outputs a symbol variation start command to the CPU 661 of the display control board 66. As a result, the CPU 661 of the display control board 66 performs three rows of fluctuation display on the liquid crystal display 19 based on the input information data of the final stop symbol data and the fluctuation pattern.
Subsequently, in S44, the CPU 461 reads the variation display processing time of the variation pattern output to the CPU 661 of the display control board 66 from the ROM 462, and waits for the processing time (S44: NO). For example, when the variation pattern is “pattern 2”, the process waits for 20 seconds. When the variation pattern is “pattern 3”, the process waits for 30 seconds. When the variation pattern is “pattern 4”, the process waits for 10 seconds. When the variation pattern is “pattern 5” or “pattern 7”, the process waits for 22 seconds. When the variation pattern is “pattern 6” or “pattern 8”, the process waits for 32 seconds. Further, when the variation pattern is “pattern 1”, each processing time stored in advance in the ROM 462 corresponding to the lost symbol is awaited.
If the processing time of the variation display processing such as “big hit variation pattern” or the variation display processing of “losing symbol” has elapsed (S44: YES), the CPU 461 sends the CPU 661 of the display control board 66 to the CPU 661 in S45. After outputting a definite stop signal for instructing to stop the change, that is, deterministic stop, to the CPU 661 of the display control board 66, the sub-process is terminated and the process returns to the main flowchart. As a result, the three rows of the changing symbols displayed on the liquid crystal display 19 are confirmed and stopped.

Next, the sub-process of the jackpot game process (S4) will be described with reference to FIGS.
As shown in FIG. 14, first, in S <b> 51, the CPU 461 executes a determination process for determining whether or not a “big hit” has occurred. This determination process reads the jackpot algebra R from the parameter storage area 463K, and determines whether the jackpot algebra R is “0” or “1”. That is, it is determined whether or not “big hit” has occurred. If the jackpot algebra R is “0”, it is determined that no “jackpot” has occurred (S51: NO), the sub-process is terminated, and the process returns to the main flowchart.

On the other hand, when the jackpot algebra R read from the parameter storage area 463K is “1”, it is determined that a jackpot has occurred (S51: YES), and in S52, the CPU 461 reads the jackpot game flag from the parameter storage area 463K. Then, a determination process for determining whether or not the jackpot game flag is ON, that is, whether or not the jackpot game flag is “1” is executed.
When the jackpot game flag is OFF, that is, when it is “0” (S52: NO), in S53, the CPU 461 executes a sub-process (see FIG. 15) of “first jackpot game process” described later. Then, the sub-process is terminated and the process returns to the main flowchart. On the other hand, when the jackpot game flag is ON, that is, when it is “1” (S52: YES), in S54, the CPU 461 executes a sub-process (see FIG. 16) of “second jackpot game process” described later. Then, the sub-process is terminated and the process returns to the main flowchart.

Here, the sub-process of the “first big hit game process” (S53) will be described with reference to FIG.
As shown in FIG. 15, in S <b> 61, the CPU 461 opens the open / close door 39 that closes the special winning opening 40.
Subsequently, in S62, whether or not 10 winning balls have been won in the grand prize opening 40, that is, whether or not the number of winning balls detected by a large winning hole count switch (not shown) has reached ten. Determine.
If the number of winning balls won in the big winning opening 40 has not reached ten (S62: NO), in S63, after the big winning opening 40 is opened, a predetermined time (in this embodiment, about It is 29 seconds.) It is determined whether or not it has elapsed. And when predetermined time has not passed since the special winning opening 40 was opened (S63: NO), the process after S61 is performed again.

On the other hand, when the number of winning balls won in the big winning opening 40 has reached 10 (S62: YES), or when a predetermined time has passed since the opening of the big winning opening 40 (S63: YES), in S64, The CPU 461 closes the open / close door 39 and closes the special winning opening 40.
Subsequently, in S65, the CPU 461 determines whether or not a prize has been won in the V zone provided in the big prize opening 40 while the big prize opening 40 is opened, that is, from the V switch (not shown) while the big prize opening 40 is opened. A determination process for determining whether or not a winning ball detection signal is input is executed.

When a winning detection signal is input from the V switch while the special winning opening 40 is opened (S65: YES), in S66, the CPU 461 determines the number of times that the special winning opening 40 is continuously opened. A determination process for determining whether or not the maximum number of continuations has been reached (in the case of the present embodiment, “16 times”) is executed. If the number of times that the special winning opening 40 is opened does not reach the predetermined maximum number of continuous times (S66: NO), the special winning opening 40 is closed for a predetermined time (in this embodiment, about 2 seconds). After the elapse of time, the processes after S61 are executed again.
In addition, when the winning detection signal is not input from the V switch while the special winning opening 40 is opened (S65: NO), or when the number of times that the special winning opening 40 is opened reaches a predetermined maximum number of times. (S66: YES), the sub-process is terminated and the process returns to the sub-process (S4) of the “big hit game process”.

Here, the sub-process of the “second big hit game process” (S54) will be described with reference to FIG.
As shown in FIG. 16, in S71, the CPU 461 reads the opening / closing number algebra N from the parameter storage area 463K, substitutes “0” for the opening / closing number algebra N, and stores it again in the parameter storage area 463K. That is, the open / close frequency algebra N is initialized.
In S <b> 72, the CPU 461 opens the open / close door 39 that closes the special winning opening 40. Subsequently, in S73, the CPU 461 reads the opening / closing number algebra N from the parameter storage area 463K, adds “1” to the opening / closing number algebra N, and stores it again in the parameter storage area 463K.
In S74, the CPU 461 waits for about 0.5 seconds after the opening / closing door 39 is opened (S74: NO). When about 0.5 seconds have elapsed since the opening / closing door 39 was opened (S74: YES), in S75, the CPU 461 closes the opening / closing door 39 and closes the special winning opening 40.
The opening time of the open / close door 39 is set to an opening time longer than 0.5 seconds (for example, about 0.7 seconds to 10 seconds) when it is difficult to win a game ball by adjusting a nail or the like. Alternatively, if there is a high possibility of winning even after 0.5 second, the opening time may be shorter than 0.5 seconds (for example, about 0.2 second to 0.4 second).

Subsequently, in S76, the CPU 461 reads the opening / closing number algebra N from the parameter storage area 463K, and determines whether the opening / closing number algebra N is “2”, that is, whether the opening / closing door 39 is opened twice. Execute the judgment process.
Note that the number of times may be any number as long as it is equal to or less than the maximum number of continuations in the process of S66 of the first jackpot game process. For example, the number of times may be any one of 1, 2, 3, 4, 5,.
If the switching frequency algebra N read from the parameter storage area 463K is not “2” (S76: NO), the CPU 461 executes the processing from S72 onward again. On the other hand, when the open / close frequency algebra N read from the parameter storage area 463K is “2” (S76: YES), the CPU 461 ends the sub-process and returns to the sub-process (S4) of the “big hit game process”. . Thereby, the open / close door 39 that closes the special winning opening 40 is opened twice for about 0.5 seconds and then closed.

Next, the sub-process of the normal symbol variation process (S5) will be described with reference to FIG.
As shown in FIG. 17, first, in S 81, the CPU 461 determines whether or not the game ball has passed through the gate 23, that is, a switch signal is input from the gate switch (not shown) via the input / output circuit (I / O) 464. A determination process for determining whether or not the process has been performed is executed.
If the switch signal is not input from the gate switch via the input / output circuit (I / O) 464 (S81: NO), the sub-process is terminated and the process returns to the main flowchart.

On the other hand, when a switch signal is input from the gate switch via the input / output circuit (I / O) 464 (S81: YES), in S82, the CPU 461 executes a count value acquisition process.
In this count value acquisition process, the CPU 461 assigns the numerical value stored in the normal symbol counter 463B when the detection signal of the game ball is input from the gate switch to the algebra U as the “normal symbol count value” at that time. Store in the parameter storage area 463K. Therefore, a numerical value of “0” to “9” is substituted for this algebra U and stored in the parameter storage area 463K.
At the same time, the CPU 461 assigns the numerical value stored in the normal symbol selection counter 463G when the game ball detection signal is input from the gate switch to the algebra X as the “normal symbol selection count value” at that time, and sets the parameter Store in the storage area 463K. Therefore, any numerical value of “0” to “3” is assigned to the algebra X and stored in the parameter storage area 463K.

In S83, the CPU 461 executes a numerical value acquisition process per ordinary symbol.
In this normal symbol numerical value acquisition processing, first, the CPU 461 reads the normal symbol flag from the parameter storage area 463K, and when the normal symbol flag is ON, that is, “1”, the “special mode (SP mode)” is set. In other words, it is determined that the lottery probability per ordinary is in a high probability state, and the “high probability per ordinary number” stored in the ROM 462 in advance (in the present embodiment, “5”, “6”, "7", "8", and "9") are read out, and this "high probability normal numerical value" is stored as "normal numerical value per symbol" in the parameter storage area 463K. On the other hand, when the normal symbol flag read from the RAM 463 is OFF, that is, “0”, it is determined that the mode is “normal mode”, that is, the normal lottery probability is in a low probability state, and is stored in the ROM 462 in advance. "Low probability ordinary numerical value" (in this embodiment, "1") is read out, and this "low probability normal numerical value" is stored in the parameter storage area 463K as "normal probability numerical value". To do.

Subsequently, in S <b> 84, the CPU 461 executes a determination process for determining whether or not “ordinary hit”.
In this determination processing for determining whether or not “ordinary hit”, first, the algebra U is read out as “ordinary symbol count value” from the parameter storage area 463K. Then, it is determined whether or not this algebra U matches any of the “values per ordinary symbol” stored in the parameter storage area 463K. If they match, “1” is assigned to the algebra S per ordinary symbol (“0” is assigned to the algebra S per ordinary symbol when the power is turned on) and stored in the parameter storage area 463K. If not, “0” is substituted into the algebra S per ordinary symbol and stored in the parameter storage area 463K.
Therefore, when the normal symbol flag is “0”, that is, in the “normal mode”, the occurrence probability of “normal hit” is 1/10 (second lottery probability). When the normal symbol flag is “1”, that is, in the “special mode”, the occurrence probability of “ordinary hit” is 5/10 (third lottery probability). As a result, in the “special mode”, the probability of “ordinary hit” is about five times that in the “ordinary mode” gaming state.

Then, the algebra S per ordinary symbol is read again from the parameter storage area 463K, and it is determined whether this algebra S per ordinary symbol is “0” or “1”. That is, it is determined whether or not “ordinary hit” has occurred.
When the algebra S per normal symbol read from the parameter storage area 463K is “1”, it is determined that “normal hit” has occurred (S84: YES), and in S85, the CPU 461 obtains the normal hit symbol. And stored in the parameter storage area 463K.
For obtaining the normal winning symbol, the CPU 461 first reads the algebra X as the normal symbol selection count value from the parameter storage area 463K. When the algebra X is “0” or “1”, the normal symbol “11” is stored in the parameter storage area 463K as the normal winning symbol. When the algebra X is “2” or “3”, the ordinary symbol “77” is stored in the parameter storage area 463K as the ordinary winning symbol.

On the other hand, when the algebra S per ordinary symbol read from the parameter storage area 463K is “0”, it is determined that “ordinary losing” has occurred (S84: NO), and in S86, the CPU 461 displays the ordinary losing symbol. Obtained and stored in the parameter storage area 463K.
For obtaining the normal lose symbol, the CPU 461 first reads the algebra X as the normal symbol selection count value from the parameter storage area 463K. When the algebra X is “0” or “1”, the normal symbol “17” is stored in the parameter storage area 463K as a normal lose symbol. When the algebra X is “2” or “3”, the normal symbol “71” is stored in the parameter storage area 463K as a normal lose symbol.

Thereafter, in S87, the CPU 461 reads the normal symbol flag again from the parameter storage area 463K, and executes a determination process for determining whether or not the normal symbol flag is ON, that is, “1”.
When the normal symbol flag read from the parameter storage area 463K is ON, that is, when it is “1” (S87: YES), in S88, the CPU 461 performs the sub-process after executing the normal symbol time variation process. End and return to the main flowchart.
In this normal symbol time variation process, the CPU 461 again reads the normal winning symbol or the normal lose symbol stored in the parameter storage area 463K, and uses these information data as the SP mode variation display data as the CPU 661 of the display control board 66. Output to. Then, the CPU 461 outputs a normal symbol variation start command to the CPU 661 of the display control board 66. As a result, the CPU 661 of the display control board 66 displays the SP mode variation display (for example, about 5 seconds to about 5 seconds to the normal symbol display unit 20 of the liquid crystal display 19 based on the inputted normal hit symbol or normal lose symbol information data. For 15 seconds). Subsequently, the CPU 461 reads the SP mode normal symbol variable display processing time (for example, about 5 to 15 seconds) output to the CPU 661 of the display control board 66 from the ROM 462 and waits for the processing time. Then, when the fluctuation display processing time of the normal symbol in the SP mode has elapsed, the CPU 461 instructs the CPU 661 of the display control board 66 to stop the fluctuation of the normal symbol, that is, to make a fixed stop. The signal is output to the CPU 661 of the display control board 66. As a result, the fixed change display of the two rows of the changing symbols displayed on the normal symbol display unit 20 of the liquid crystal display 19 is “11”, “77” normal hit symbols or “17”, “71” normal lose symbols. Is done.

On the other hand, when the normal symbol flag read from the parameter storage area 463K is OFF, that is, “1” (S87: NO), in S89, the CPU 461 executes the normal symbol normal variation process, and then executes the sub-process. End and return to the main flowchart.
In the normal symbol normal variation process, the CPU 461 reads the normal winning symbol or the normal lose symbol stored in the parameter storage area 463K again, and uses the information data as the normal mode variation display data as the CPU 661 of the display control board 66. Output to. Then, the CPU 461 outputs a normal symbol variation start command to the CPU 661 of the display control board 66. As a result, the CPU 661 of the display control board 66 displays the fluctuation display of the normal mode (for example, about 40 seconds to about 40 seconds to the normal symbol display unit 20 of the liquid crystal display 19 based on the inputted normal hit symbol or normal lose symbol information data. For 55 seconds). Subsequently, the CPU 461 reads from the ROM 462 the normal symbol variation display processing time (for example, about 40 seconds to 55 seconds) output to the CPU 661 of the display control board 66, and waits for the processing time. When the normal symbol fluctuation display processing time in the normal mode has elapsed, the CPU 461 instructs the CPU 661 of the display control board 66 to stop the fluctuation of the normal symbol, that is, to confirm and stop. The signal is output to the CPU 661 of the display control board 66. As a result, the fixed change display of the two rows of the changing symbols displayed on the normal symbol display unit 20 of the liquid crystal display 19 is “11”, “77” normal hit symbols or “17”, “71” normal lose symbols. Is done.

Next, the sub-process of the normal hit game process (S6) will be described with reference to FIG.
As shown in FIG. 18, first, in S <b> 91, the CPU 461 executes a determination process for determining whether or not it is “normal hit”.
The CPU 461 reads the algebra S per ordinary symbol from the parameter storage area 463K, and when the algebra S per ordinary symbol is “1”, the “ordinary hit” occurs. On the other hand, when the algebra S per ordinary symbol is “0”, it is determined that “ordinary loss” has occurred.
Then, when the algebra S per ordinary symbol S read from the parameter storage area 463K is “0” (S91: NO), the CPU 461 determines that “ordinary loss” has occurred and ends the sub-process. Return to the main flowchart.

On the other hand, when the algebra S per ordinary symbol S read from the parameter storage area 463K is “1”, it is determined that “ordinary hit” has occurred (S91: YES), and in S92, the CPU 461 displays a solenoid (not shown). To open the tulip-type electric accessory 24 (in FIG. 2, the tulip-type electric accessory 24 is in a state represented by a solid line).
In S93, the CPU 461 determines whether a winning signal to the tulip-type electric accessory 24, that is, a pachinko ball detection signal from a tulip winning switch (not shown) is input via the input / output circuit (I / O) 464. A determination process is performed to determine whether or not.
When the pachinko ball detection signal from the tulip winning switch is not input via the input / output circuit (I / O) 464 (S93: NO), the processing from S92 is executed again.

  On the other hand, when the detection signal of the pachinko ball from the tulip winning switch is input via the input / output circuit (I / O) 464 (S93: YES), the solenoid (not shown) is turned off in S94. The electric motor combination 24 is closed (in FIG. 2, the tulip electric appliance 24 is in a state represented by a broken line), the sub-processing is terminated, and the process returns to the main flowchart.

  Here, the liquid crystal display 19 constituting the special symbol display device 18 functions as a variable symbol display means and a normal symbol display means. Further, the portion of the liquid crystal display 19 that displays the three rows of changing symbols functions as a changing symbol display unit. Moreover, the normal symbol display part 20 of the liquid crystal display 19 functions as a normal symbol display part. Further, the gate 23 functions as a game ball detecting means. Moreover, the tulip type electric accessory 24 functions as a normal electric accessory. The CPU 461, the ROM 462, and the RAM 463 constitute a jackpot determining means, a normal winning determining means, a bonus game giving means, a jackpot symbol selecting means, a first special game control means, a second special game control means, and a normal game mode setting means. . Further, the normal winning symbols “11” and “77” displayed on the normal symbol display unit 20 constitute a normal winning symbol. Each jackpot symbol “111”, “222”, “333”, “444” constitutes a first jackpot symbol group. Each jackpot symbol “123”, “341”, “234”, “412” constitutes a second jackpot symbol group. Further, the gaming state in which the tulip-type electric accessory 24 is open is a privilege gaming state. Further, when the jackpot game mode is the first jackpot game, the first special game state is set. When the jackpot game mode is the second jackpot game, the game is in the second special game state. Further, when the big hit lottery mode is the normal mode, it is the first normal game mode. Further, when the big hit lottery mode is the probability variation mode, it is the second normal game mode.

Therefore, in the pachinko machine 1 according to the present embodiment, the jackpot is randomly selected, and after the fluctuation symbols in the three rows are changed, the game stops at the jackpot symbol of any one of “111”, “222”, “333”, and “444”. In such a case, the first jackpot game that allows the grand prize winning opening 40 to be opened up to 16 times is given, and after the three rows of fluctuation symbols fluctuate, “123”, “341”, “234”, “412” When the game is stopped at any of the jackpot symbols of "", a second jackpot game is awarded in which the big prize opening 40 is opened twice for about 0.5 seconds. For this reason, when the jackpot is lottery and the first jackpot game is awarded, the big winning opening 40 is opened and the pachinko ball easily wins from the big winning opening 40, so that the player can quickly It becomes possible to easily acquire many prize balls. On the other hand, when the second jackpot game is awarded, even if the grand prize opening 40 is opened twice, it is difficult to win a game ball because each opening time is about 0.5 seconds. It becomes difficult to acquire a ball. Therefore, the player's expectation for the acquisition of the first jackpot game can be increased, and the interest can be increased.
In addition, when the second jackpot game is awarded, after the second jackpot game is finished, the change symbols are “111”, “222”, “333”, “444”, “123”, “341”, Until it stops at the jackpot symbol of “234” or “412”, the probability of giving the normal hit is higher than the normal time (in this embodiment, it is 1/10 of the probability) (in this embodiment, 5/10 probability)), so that the number of game balls won per unit time for the tulip-type electric player 24 is higher than usual, and the player can play a pachinko game for a long time. A decrease in game balls can be easily prevented, and a pachinko game can be continued for a long time. In addition, after the second jackpot game is over, it is possible to prevent a decrease in game balls, so that a player's expectation for acquiring the first jackpot game can be increased for a long time, and interest can be increased. .

Each time the jackpot is drawn, the first jackpot game or the second jackpot game is drawn with a probability of 4/8 or 2/4, and after the first jackpot game is over, either of the variable symbols is a jackpot symbol. Until the game stops, the normal win is drawn with a probability of 1/10, and after the second jackpot game is over, the normal win will be held until the variable symbol stops at one of the jackpot symbols. A lottery with a probability of 5/10. As a result, one game mode is selected from two types of game modes (special mode (SP mode) and normal mode) that differ in the lottery probability of normal winning every time the first jackpot game or the second jackpot game ends. Since it is set as the normal winning lottery mode, it is possible to diversify the normal gaming state and increase the interest of the player, and can be strongly attracted to the pachinko game.
Furthermore, by changing the lottery probability of granting the first jackpot game or the second jackpot game, the special mode in which the lottery probability of the regular bonus set after the end of the first jackpot game or the second jackpot game is different ( SP mode) and normal mode can be accurately controlled, and by changing the first game mode selection table 71 and the second game mode selection table 72, special mode (SP mode) and normal mode Since it is possible to accurately control the mode selection lottery probability, it is possible to easily achieve a profit balance between the player and the game store.

In addition, when the probability change mode is set as the jackpot lottery mode, the probability of winning the jackpot is increased, so that the player's expectation for acquiring the probability change mode can be increased and attracted to the pachinko game strongly. it can.
In addition, when the probability variation mode is set as the jackpot lottery mode, the probability that the jackpot will be awarded is increased. Therefore, after the player finishes the second jackpot game, “123”, “341”, “234”, “ It is possible to increase the sense of expectation for the stoppage with any of the “412” jackpot symbols, and even if the pachinko game is continued for a long time, the interest in winning the jackpot is strongly attracted and the interest can be increased. In addition, even if the second jackpot game is awarded twice in a row, the probability that the next jackpot will be awarded will surely increase, so the player's expectation for acquiring the probability variation mode can be increased, and the pachinko game Can attract strongly.
Furthermore, when the normal hit game mode is the special mode, the change of the normal symbol stops in a shorter time than when the normal hit game mode is the normal mode, so that the tulip type electric accessory 24 is opened. Since the number of times that the tulip-type electric accessory 24 is opened per unit time increases, the winning of the game ball to the tulip-type electric accessory 24 is higher than usual, and the player has a long time. Even if a pachinko game is played, a decrease in the number of game balls can be more easily prevented, and the pachinko game can be continued for a longer time.

  In addition, this invention is not limited to the said embodiment, Of course, various improvement and deformation | transformation are possible within the range which does not deviate from the summary of this invention. For example, the following may be used.

  (A) In the above embodiment, when the second jackpot game is awarded, after the second jackpot game ends, the change symbols are “111”, “222”, “333”, “444”, “123” ”,“ 341 ”,“ 234 ”, and“ 412 ”, the probability of giving a normal hit is higher than normal (in the above-described embodiment, it is 1/10 of the probability) until it stops at the jackpot symbol. (In the above-described embodiment, the probability is 5/10.) The lottery is normally performed (the probability is 1/10 in the above-described embodiment). , A probability of 1/20 to 1/30). As a result, when the second jackpot game is awarded, the number of prize balls that can be obtained by the player is surely reduced as compared with the case where the first jackpot game is awarded. Can raise the sense of expectation.

  (B) In the above embodiment, the variable symbol and the normal symbol are variably displayed on the liquid crystal display 19, but only the variable symbol is variably displayed on the liquid crystal display 19, and the normal symbol is displayed on a liquid crystal display or the like arranged separately. May be displayed in a variable manner. Thereby, an ordinary symbol can be displayed larger, visibility can be improved, and interest can be increased.

(C) In the above embodiment, the gate 23 is disposed. However, in place of the gate 23, a winning opening connected to an unillustrated prize ball bowl on the back of the game board 2 is provided, and a winning is detected at the winning opening. The winning symbol switch may be provided, and the normal symbol may be changed based on the winning information for the winning symbol.
Thus, the prize to the winning port with normal symbol starts fluctuation, since a predetermined number of prize balls are paid out, it is possible to gain more prize balls without "big hit" is given, The player can play a pachinko game for a longer time while easily preventing a decrease in game balls.
