Description

  The present invention relates to a pachinko gaming machine, and more particularly, to a pachinko gaming machine that wins in a jackpot lottery and opens and closes a grand prize winning opening over a plurality of rounds.

  Conventionally, in the mainstream pachinko machines, a big win lottery was performed in response to the winning of a game ball at the start winning opening, and when winning in that lottery, the big prize opening device operates as a big win game, The closed special winning opening is opened and closed over a plurality of rounds (for example, 15R). Each round ends after opening the grand prize opening and closing the grand prize opening after a specified number (for example, 10) of game balls have been awarded to the grand prize opening or after a specified time (for example, about 30 seconds). The special prize opening device is controlled so as to form an opening / closing pattern for continuing this round for a plurality of rounds.

  Normally, the specified time for each round is the same for all rounds, and when a game ball is normally continuously fired, a specified number of game balls can be awarded to the big prize opening during the round (easy to win) ) The time is set. Therefore, when the number of jackpot rounds to be executed in the jackpot game is uniform, the opening / closing pattern is also uniform, and the player finally has a substantially constant number (for example, ten awards for one winning game ball to the jackpot). When there are spheres, the specified number = 10, and when the number of rounds per jackpot = 15R, 10 × 10 × 15 = 1500 balls) can be obtained.

  Here, when winning in the jackpot lottery, the first two rounds of the first prize winning pachinko machine, which is alternatively selected from the number of rounds with different jackpot round numbers (for example, 2R and 15R) A pachinko gaming machine that performs a plurality of rounds (for example, 15R) by performing dummy round opening / closing in a short time, and then performing normal opening / closing of the 1R big prize opening as usual, is known. In the pachinko machines described in Patent Documents 2 and 3, when the player changes the winning probability of the jackpot lottery, the number of jackpot rounds and the specified time are changed according to the winning probability.

An opening / closing pattern in which a predetermined number (for example, 10) of game balls are won after the game is opened, or one of the first and second grand prize winning openings 13a, 14a is closed by a lapse of a predetermined time and a plurality of rounds are completed. In addition to controlling the first and second big prize opening devices 13 and 14, the winning probability of the jackpot lottery is set to a predetermined low probability (for example, about 1/300) when the winning probability is lost in the probability varying lottery. When winning by lottery, a high probability (for example, about 1/30) higher than the low probability is set.

  The main control device 21 can execute each round that can be executed with respect to the second grand prize opening device 14 and opens and closes the second big prize opening 14a one or more times when a predetermined condition is satisfied as will be described later. A plurality of types of opening / closing patterns executed over a plurality of rounds (for example, 10 rounds), each of which stores a plurality of types of opening / closing patterns having a non-probability changing non-probability opening / closing pattern and a probability changing opening / closing pattern. A ROM as a pattern storage means is provided.

  In this plurality of types of opening / closing patterns, the number of all rounds to be executed (10 rounds) is the same, and the opening / closing timing of the second big prize winning opening 14a for a predetermined number of times (for example, 5 times) in one or more rounds on the head side. Are set in common and at least one of the same rounds is set to have a different specified time, and a predetermined number of times (for example, 2 times) of the middle stage executed after execution of one or more rounds on the head side The opening / closing timing of the dummy opening / closing of the second grand prize opening 14a is made common, and the opening / closing time (for example, 0.5 seconds) by each dummy opening / closing is set to each opening / closing of the second big winning opening 14a other than the dummy opening / closing (other opening / closing patterns). ) Is set to be shorter than the opening time, and the number of last rounds (for example, 7) executed after a predetermined number of dummy opening / closing operations is all the same. Are and set in the rearmost side round a defined time (e.g., about 30 seconds) Number of defining (10) × 2 seconds (= 20 seconds) or longer.

  Further, the main control device 21 selectively selects one of the open / close patterns in the ROM when winning in the jackpot lottery, and here, in the case of being lost in the probability variation lottery, one non-selection pattern is selected from the ROM. When a probability variation opening / closing pattern is selected and winning by chance variation lottery, one probability variation opening / closing pattern is selected from the ROM, and the second big prize opening device 14 is controlled so as to become the selected opening / closing pattern. That is, the main control device 21 constitutes an opening / closing pattern selection means and an opening / closing control means. In addition, when the probability change opening / closing pattern is selected by the main control device 21, the sub control device 25 notifies the fact that a specified number of game balls have won during the round of the head side wins in the probability change lottery. To control.

  In the main control device 21, a standard opening / closing pattern that can be executed for the first grand prize opening device 13 and that is executed over a plurality of rounds (for example, 10 rounds) is stored in the ROM, and is won in the big win lottery. In addition, when the non-probability changing opening / closing pattern and the probability changing opening / closing pattern are not executed, one standard opening / closing pattern is selected from the ROM, and the first big prize opening device 13 is controlled so as to become this standard opening / closing pattern.

  Next, a plurality of types of opening / closing patterns and processing / control executed by the main control device 21 will be described in detail and specifically. The “round” will be described as “R” as appropriate.

  First, the plurality of types of opening / closing patterns have a uniform number of rounds of 10R, and one type of non-probable opening / closing pattern A shown in the time charts of FIGS. 4 and 5 and the time charts of FIGS. There are five types of probability change opening / closing patterns B to F shown and one standard opening / closing pattern G (not shown), each of which has a specified number of 10 rounds and an interval time between rounds of 1.5 seconds. Has been.

  As shown in FIG. 4, the non-probability variable opening / closing pattern A includes 1R and 2R that open and close the second big prize opening 14a twice in each of the first 1R to 3R, and 3R that opens and closes the second big prize opening 14a once. The probability variation opening / closing pattern B has 1R, 2R for opening and closing the second big prize opening 14a twice in each of the first side 1R to 3R and 3R for opening and closing the second big prize opening 14a once, Probability change opening / closing pattern C opens and closes 2R and 2nd big prize opening 14a which open and close 1R which opens and closes 2nd big prize opening 14a once in 2R and 2nd big prize opening 14a in 1R-3R of the head side. 3R.

  Further, the probability variation opening / closing pattern D has 1R, 2R that opens and closes the second grand prize opening 14a once in the top side 1R to 3R, and 3R that opens and closes the second major prize opening 14a three times. The pattern E has 1R that opens and closes the second big prize opening 14a once in the first side 1R and 2R, and 2R that opens and closes the second big prize opening 14a four times. In 1R, the second big prize opening 14a is opened and closed five times (having 1R).

  In the opening / closing patterns A to F, among the opening and closing of the second big winning opening 14a in the five rounds in the first round, each opening and closing of the second big winning opening 14a excluding the opening and closing of the last second big winning opening 14a. Opening time: 3 seconds is a specified number; 10 (pieces) × 1/5 second = 2 seconds or more and a prescribed number; 10 (pieces) × 4/5 seconds = 8 seconds or less Opening time by opening / closing the second grand prize winning opening 14a; 6 seconds is set to the time of 2 seconds or more and 8 seconds or less. It is set to 5 seconds.

  In this way, the non-probability change opening / closing pattern A and the probability change opening / closing patterns B to F are the opening / closing timings of the second large winning opening 14a on the leading side (however, strictly speaking, opening / closing when a prescribed number of game balls do not win) (Timing) is set in common, and a specified time of a round for opening and closing a plurality of times (for example, 1R 3 seconds + 3 seconds = 6 seconds of the non-probability variable opening / closing pattern A) is the total opening time of the second grand prize winning opening 14a. As specified, the non-probability variable open / close pattern A and the probability variable open / close patterns C to F are set so that at least one specified time of the same round is different.

  The non-probability variable opening / closing pattern A is a specified time of 1R and 2R for opening and closing the top second big prize opening 14a twice; 6 seconds, and the probability variation opening / closing pattern B is the second big prize opening 14a on the front side. 1R, 2R specified time to open and close 2 times each; 6 seconds, and the probability variation open / close pattern C is 1R specified time to open and close the top second prize winning opening 14a twice; 6 seconds and 2 times open and close 3R specified time; 9 seconds is set to a specified number; 10 (pieces) × 1 second = less than 10 seconds.

  The probability variation opening / closing pattern D is a 3R specified time for opening and closing the top second big prize opening 14a three times; 12 seconds, and the probability variation opening / closing pattern E is a time when the top second big prize opening 14a is opened and closed four times. Specified time of 2R; 15 seconds, and the probability variation open / close pattern F is a specified time of 1R for opening and closing the top second prize winning opening 14a five times; a specified number of 18 seconds, respectively (10) × 1 second = set to a time of 10 seconds or more.

  Further, as shown in FIG. 5, the non-probability variation opening / closing pattern A and the probability variation opening / closing patterns B to D are performed at the top two times of the middle 4R second big winning opening 14a executed after the execution of the first side 1 to 3R. Opening time by each dummy opening and closing; 0.5 seconds, and the probability variation opening and closing pattern E is the two dummy of the second 3rd prize winning opening 14a of the middle 3R executed after the execution of the first 1R, 2R Opening time by opening and closing: 0.5 seconds, and the probability variation opening and closing pattern F is the opening by each dummy opening and closing of the 2nd and 2nd 2nd big winning opening 14a of the middle stage executed after execution of 1R on the top side. Time: 0.5 seconds is set to a specified number; 10 (pieces) × 1/5 seconds = 2.

As described above, the plurality of types of opening / closing patterns A to F have three types of opening / closing patterns in which the round in which the predetermined number of times of dummy opening / closing is executed is different, and the predetermined number of times of dummy opening / closing is executed in one round. And an opening / closing pattern executed over a plurality of rounds .

  Further, the non-probability changing opening / closing pattern A and the probability changing opening / closing patterns B to D execute opening / closing of the second major winning opening 14a in the same 4R after the dummy opening / closing of the second major winning opening 14a of the middle 4R. After the dummy opening / closing of the middle 3R second prize opening 14a, the process shifts to 4R and the second big prize opening 14a is opened / closed, and the probability variation opening / closing pattern F is the 2R, 3R second big prize opening 14a of the middle board. The number of 4R to 10R on the rearmost side executed after the dummy opening / closing of the second large winning opening 14a in the middle stage is changed to 4R after the dummy opening / closing of the second is performed, and the second large winning opening 14a is opened / closed; All are the same, and the specified time of 4R to 10R; about 30 seconds is set to a specified number; 10 (pieces) × 2 seconds = 20 seconds or more.

  As described above, the plurality of types of opening / closing patterns A to F include an opening / closing pattern and a dummy opening / closing that are executed continuously in the same round as the round in which the dummy opening / closing is executed. And an opening / closing pattern to be executed in a round next to the round in which the is executed.

  Next, processing and control executed by the main control device 21 will be described based on the flowcharts of FIGS. 7 to 14 and the tables of FIGS. 15 and 16. Note that the program for executing this processing / control and the related information of the tables of FIGS. 15 and 16 are stored in the ROM of the main controller 21.

  First, as shown in FIG. 7, in the main process of the main controller 21, the random number update process (S1), the start port SW process (S2), the gate SW process (S3), the special symbol process (S4), and the normal symbol process. (S5), winning prize opening process (S6), electric chew process (S7), prize ball process (S8), and output process (S9) are sequentially executed, and then the initial value random number update in S10 and the fluctuation pattern in S11 are performed. The random number is updated repeatedly, and the processing of S1 to S9 is executed by interruption processing at every minute time interval.

  As shown in FIG. 8, in the start port SW process of S2, when the start port SW11d is turned on (S20; Yes), and when the special symbol hold number U is less than 4 (S21; Yes), the hold number U is incremented to U + 1 (S22), and the jackpot random number, jackpot symbol random number, reach random number, and fluctuation pattern random number are acquired and stored (S23), and the process returns. Each random number is sequentially updated within a predetermined range in the random number update process of S1, and in S23, a random number generated when the start port SW11d is turned on is acquired and stored.

  As shown in FIG. 9, in the special symbol processing of S4, when the big win is not being hit (S30; No), when the special symbol is not changing (S31; No), the reserved number U of the special symbol is 1 or more. In this case (S32; Yes), the number U of holdings is decremented to U-1 (S33), and the jackpot determination process (S34) is executed.

  As shown in FIG. 10, in the jackpot determination process of S34, the oldest jackpot random number acquired and stored in S23 is determined (S50), and the jackpot random number is in the normal gaming state as shown in FIG. Matches the jackpot specific random number (for example, “3”) at a rate of 1/300, and in the case of the probability variation gaming state, the jackpot specific random number (for example, “3”, “7”, “ 37 "..) is determined to be a big hit, and if it matches a small hit specific random number (for example," 0 "," 50 "," 100 "..), it is determined to be a big hit.

  Then, in the case of jackpot (S51; Yes), the oldest jackpot symbol random number acquired and stored in S23 is determined (S52), and based on the jackpot symbol random number, seven types of jackpot symbols AG as the jackpot symbol Is selected and set (S53), and the process returns. When the jackpot symbol is selected in S53, one of the jackpot symbols A to G is selected with reference to the table of FIG. In addition, in FIG. 16, the range of the jackpot symbol random number, the ratio at which each jackpot symbol A to G is selected, and the like are shown as examples.

  Here, S23, S52, etc. correspond to the probability variation lottery, and when the jackpot symbol A is selected, the probability variation lottery results in a loss, and the normal gaming state is set after the jackpot game, and the winning probability of the jackpot lottery is low. When one of the jackpot symbols B to G is selected, the winning game is set in the probability variation lottery, the probability variation gaming state is set after the jackpot game, and the winning probability of the jackpot lottery is 1 with a high probability. / 30.

  In addition, as shown in FIG. 16, when the jackpot symbol A is selected, the opening / closing pattern A corresponding to the jackpot symbol A is selected, and when one of the jackpot symbols B to G is selected, the jackpot symbol A One of the open / close patterns B to G corresponding to the symbols B to F is selected. That is, S23, S52, S53, etc. correspond to the open / close pattern selection means.

  On the other hand, if S51; No, that is, if it is not a jackpot, based on the jackpot symbol random number, if the jackpot is small (S54; Yes), the jackpot symbol is set (S55), if it is not a jackpot (S54; No), the lost symbol is set (S56) and the process returns.

  As shown in FIG. 9, after the jackpot determination process in S34, a variation pattern selection process (S35) is executed, based on the jackpot random number, jackpot symbol random number, reach random number, variation pattern random number, etc. acquired and stored in S23. The variation pattern is selected, the variation pattern command is set (S36), the variation of the special symbol is started on the special symbol display 18a (S37), the measurement of the variation time is started (S38), and the process returns. Note that the command set in S36 and the command set in the following description are output to the sub-control device 25 in the output process of S9 in FIG.

  On the other hand, when S31: Yes, that is, when the special symbol is changing, the change time started from S38 reaches the predetermined time, and when the change time ends (S39; Yes), the change stop command is set. (S40) The special symbol is stopped by the special symbol display 18a (S41), the symbols set in S53, S55, and S56 are displayed as the lottery results, and the variation time is reset (S42). (S43) is executed and the process returns.

  As shown in FIG. 11, in the stopping process of S43, when the winning time is not a win (S60; No), and when the number of time reductions J is not 0 (S61; No), the time reduction number J is decremented to J-1. (S62) After that, when the number of time reductions J becomes 0 (S63; Yes), the normal gaming state is set (S64) and the process returns. In addition, when the number of hourly J is not 0, the probability variation gaming state or the hourly gaming state is set. In these gaming states, the fluctuation time of the normal symbol is shorter than that in the normal gaming state, and The time for opening the start winning opening 11b becomes longer.

  On the other hand, if S60: Yes, that is, if it is a win or not a small win (S65; No), a probability variation gaming state setting process (S66) is executed, a big hit start command is set (S67), and a big win is started. (S68), return. S65: Yes, that is, in the case of a small hit, a small hit start command is set (S69), a small hit is started (S70), and the process returns.

  When the big hit is started, one of the first and second big prize opening devices 13 and 14 is operated so as to be an opening / closing pattern selected from seven types of opening / closing patterns A to G. In addition, the small win does not belong to the big win, and when the small win is started, the first and second big prize winning openings 13a and 14a are opened and closed several times (for example, twice) so that One of the second grand prize opening devices 13 and 14 operates.

  Next, as shown in FIG. 12, in the big winning opening process of S6, when a big hit is made (S80; Yes), one of the first and second big winning openings 13a, 14a is opened at the beginning of the big win. If the previous opening is being performed (S81; Yes), and if the opening time has elapsed (S82; Yes), the process proceeds to S83. S82: If No, that is, if the opening time has not elapsed, the process returns.

  On the other hand, when S81; No, that is, when it is not opening, as shown in FIG. 13, when one of the first and second big prize winning openings 13a and 14a is not open (S97; No), at the end of the jackpot When one of the first and second winning prize openings 13a and 14a is not closed after closing (S98; No), and when the interval time between rounds has elapsed (S99; Yes), the process proceeds to S83.

  As shown in FIG. 12, in S83, R is incremented to R + 1. This R is reset to 0 at the start of jackpot. Next, with respect to the opening / closing pattern set in S53 of FIG. 10 and selected according to the jackpot symbol, from the information of the opening / closing pattern stored in the ROM of the main control device 20, the big prize opening device (first , Any one of the second grand prize opening devices 13, 14), the prescribed time of the R, the number of opening / closing of the big prize opening 13a, 14a in the R, and the respective opening times are acquired (S84). Then, one of the specified first and second big prize opening devices 13 and 14 is operated, and one of the first and second big prize opening 13a and 14a is opened (S85), and the process proceeds to S86.

  For example, in the case of the opening / closing pattern A shown in FIG. 4, it is executed by the second grand prize opening device 14, and the specified time of the 1R is about 6 seconds, and the number of times of opening / closing the second big prize opening 14a in 1R is It becomes twice, and the opening time of each second grand prize winning opening 14a in 1R becomes 3 seconds. On the other hand, when one of the first and second grand prize winning openings 13a and 14a is open (S81; No, S97 in FIG. 13; Yes), the process proceeds to S86.

  In S86, an open / close process during the round is executed. As shown in FIG. 14, in the open / close process during the round, based on the information of the open pattern acquired in S84, first, the second big prize is won for the R being executed. It is determined whether or not the mouth 14a is a round that opens and closes multiple times (S100). If S100; S100: If Yes, it is determined whether or not the second big prize opening 14a is being opened (S101). If S101; Yes, it is decided whether or not the second big prize opening 14a is finally opened (S102). S102: If Yes, return.

  In the case of S102; No, it is determined whether or not the set opening time has elapsed with respect to the current opening of the second big prize opening 14a (S103), S103; Returns in the case of No, S103; The winning opening 14a is closed (S104) and the process returns. On the other hand, in the case of S101; No, it is determined whether or not the second big prize opening 14a is closed (S105). In S105; No, the process returns, and in the case of S105; Yes, the current second big prize opening 14a is determined. It is determined whether or not the set closing time has passed for blocking (S106). If S106; No, the process returns, and if S106; Yes, the second big prize opening 14a is opened (S107), and the process returns.

  As shown in FIG. 12, after the opening / closing process during the round of S86, it is determined in S87 whether or not the specified time acquired in S84 has elapsed since the opening of one of the first and second prize winning openings 13a, 14a. In the case of S87; No, in S88, it is determined whether or not the number of game balls C won in this R is 10 of the prescribed number of winnings, and in the case of S88; No, the process returns. When an affirmative determination is made in either S87 or S88 (S87; Yes or S88; Yes), the open first and second big prize winning openings 13a, 14a are closed (S89).

  Next, it is determined whether or not the current R (R updated in S83) is the maximum R (10R) (S90). If S90; No, the process returns. If S90; Yes, R is 0. It is reset (S91), ending is started (S92), and the process proceeds to S93. On the other hand, also in the case of ending (S81; No, S97 in FIG. 13; No, S98 in FIG. 13; Yes), the process proceeds to S93. In S93, it is determined whether or not the ending time has elapsed. If S93; No, the process returns. If S93; Yes, the jackpot ends (S94), and the process returns.

  On the other hand, in the case of S80; No, if small hit is not made (S95; No), the process returns. If small hit is made (S95; Yes), the small hit process (S96) is executed, and the process returns. As described above, when the jackpot is won, one of the large winning openings 13a, 14a is opened / closed by an opening / closing pattern selected from a plurality of types of opening / closing patterns A to G. That is, the main step of the special winning a prize opening process corresponds to the opening / closing control means for controlling the special winning opening apparatus so as to be the opening / closing pattern selected by the opening / closing pattern selection means.

  Here, when game balls are continuously fired in the game area 5 at intervals of 0.6 seconds, it is assumed that one game ball wins about 1 second in the open second big prize opening 14a. FIG. 6 shows a winning pattern of the game balls to the second big winning opening 14a in each of .about.F. That is, in the open / close patterns A to C, it is difficult for a predetermined number of game balls to win the second big prize opening 14a during execution of 1R to 3R, and about 18 game balls win 1R to 3R.

  On the other hand, in the opening / closing pattern D, a prescribed number of game balls are likely to win the second big prize opening 14a during the execution of the top 3R, and about 16 game balls win in 1R to 3R. During execution of the top 2R, it is easy for a prescribed number of game balls to win the second big prize opening 14a, and about 13 game balls win 1R, 2R. In the open / close pattern F, the top 1R During execution, it is easy to win a prescribed number of game balls in the second big prize opening 14a, and about 10 game balls win in 1R.

  As described above, the number of game balls to be awarded to the second grand prize opening 14a during execution of the first round differs depending on the opening / closing patterns A to F, and the prescribed number of game balls to the second big prize opening 14a is different. Ease of winning will be different. Note that the winning pattern is actually random due to the relationship between the obstacle nail 10 and the launching speed of the game ball, and in FIG. 6, the specified number of game balls can win in a round in which the specified number of game balls do not win. There is also sex.

  On the other hand, when the probability changing opening / closing pattern is selected by the opening / closing pattern selecting means, the sub-control device 25 notifies that the player has won in the probability changing lottery when a prescribed number of game balls are won during the first round. It corresponds to the notification control means for controlling the above. The sub-control device 25 receives, from the main control device 21, information on the number of game balls that have won the second big prize opening 14a during execution of the head-side round. And execute. Specific examples thereof are as follows.

  Regardless of which one of the opening / closing patterns A to F is selected, first, the pre-notification effect in which winning / losing, superiority / inferiority, etc. are determined from the 1st R, mainly using the image display 16 and the sound effect from the speaker 32. The level of winning or losing, superiority or inferiority is fluctuated and displayed on the basis of the winning of the game ball at the second grand prize opening 14a, the passage of time, the update of the round, and the like. In the case of the open / close patterns D to F, since a specified number of game balls are likely to win the second grand prize opening 14a, the level of winning or losing, superiority or inferiority is the highest level when the specified number of game balls are won. It will be displayed in the form of reaching, and it will be informed that it has been won in the probability variation lottery.

According to the pachinko gaming machine 1 described above, the following operations and effects are achieved.
A jackpot lottery is performed in response to a winning of a game ball at the start winning ports 11a, 11b, and a jackpot game is generated when a winner is won in the lottery. In this case, any one of the seven types of opening / closing patterns A to G is selectively selected, and in the jackpot game, the first and second big prize opening devices 13 and 14 so as to be the opening / closing pattern. Is controlled.

  When any one of the six types of opening / closing patterns A to F is alternatively selected, the second grand prize opening device 14 is activated, and the second big prize opening 14a is shown in FIGS. Opened and closed as shown. Here, since the six types of opening / closing patterns A to F have the same opening / closing timing of the second major winning opening 14a in the first one or a plurality of rounds, as long as the player sees this opening / closing operation, From the beginning of the jackpot game, it cannot be determined which open / close pattern is being executed.

  Further, when the second grand prize opening device 14 is operated, the player can set up the special symbol display 18a by complicating the display patterns of the jackpot symbols A to F displayed on the special symbol display 18a as a whole. It is difficult to determine which of the jackpot symbols A to F is displayed, that is, which of the open / close patterns A to F corresponding to the jackpot symbols A to F is selected. It is difficult to determine whether or not the winner is won.

  The player recognizes that the jackpot has been made mainly from the jackpot display displayed on the image display 16, and the first and second first prize opening devices 13, 14 are operated to open and close the first and first The game balls are continuously fired to win the game balls in one of the two major winning openings 13a, 14a.

  Here, when the second grand prize opening device 14 is operated, in one or a plurality of rounds on the top side, as described above, for example, using the image display 16, the presence / absence of winning in the probability variation lottery and the attendant A pre-notification effect is performed. When any one of the opening / closing patterns D to F is selected, it is easy to win a prescribed number of game balls during the first round, and when the prescribed number of game balls are won, The player is rejoiced because the winner is notified.

  On the other hand, when any one of the opening / closing patterns A to C is selected, it is difficult to win a specified number of game balls during the first round, and even if the winning lottery is won, it is not notified. So players are discouraged. However, when either of the opening / closing patterns B and C is selected, it is not only informed that the winning is made in the probability variation lottery, that is, even if the winning in the probability variation lottery is not notified, Since there is a possibility that the player has won, the player can have an expectation in that respect, however, the case where the player has not actually won in the probability variation lottery is included.

  According to this pachinko gaming machine 1, a plurality of types of opening / closing patterns A to F cannot be obtained in a predetermined number of times of dummy opening / closing executed in the middle board, and the leading side of the middle board before the dummy opening / closing. And the last round after the dummy opening / closing, each of the rounds is a unique opening / closing pattern for getting a ball, and the opening / closing patterns A to D, E and F are rounds in which the dummy opening / closing is performed a predetermined number of times in the middle. Since the number of rounds on the front side can be made different, the plurality of types of opening / closing patterns A to F are executed on the leading side and the trailing side by using a predetermined number of dummy opening / closings in the middle stage. By adjusting the number of rounds to be adjusted, the player can adjust the number of balls played by the jackpot game, increasing the degree of freedom to set the gaming machine specs including the number of balls to be played and the jackpot probability, etc., taking into account the ballpark percentage, and the jackpot game In Whiteness can be to create and improve the game of.

  The plurality of types of opening / closing patterns A to F include opening / closing patterns A to D for performing opening / closing of the second big prize opening 14a after a predetermined number of times of dummy opening / closing in the same round as the dummy opening / closing, and dummy opening / closing. Since the opening / closing patterns E and F executed in the next round of the round to be executed are included, these opening / closing patterns A to D and E and D have different rounds in which the dummy opening / closing is performed a predetermined number of times. The number of rounds executed on the front side and the last side can be adjusted by a predetermined number of dummy opening / closing operations executed in the middle stage.

  The plurality of types of opening / closing patterns A to F include the opening / closing patterns A to E in which a predetermined number of dummy opening / closing operations are executed in one round and the opening / closing patterns F to be executed over a plurality of rounds. ~ E and F are different rounds in which the predetermined number of dummy opening / closing is executed, and the number of rounds executed on the front side and the tail side by the predetermined number of dummy opening / closings executed in the middle stage respectively. Can be adjusted. Since the opening time (0.5 seconds) for each dummy opening / closing is set to a time less than the specified number (10) × 1/5 second (= 2 seconds), the dummy opening / closing executed in the middle stage is substantially It is possible to prevent getting a ball.

  The plurality of types of opening / closing patterns A to F are set so that the opening / closing timing of the second big prize opening 14a in the first round is set in common and the specified time of at least one same round is made different. The number of the opening and closing patterns A to F in the first round can be made different, and the plurality of types of opening and closing patterns A to F all have the same number of the last rounds executed after a predetermined number of times of dummy opening and closing, and Since the specified time (about 30 seconds) of the last round is set to a time equal to or more than the specified number (10) × 2 seconds (= 20 seconds), the specified number of rounds in the last round It is possible to make it easy to win the game balls of the player, so that the last ball on the last side can be made uniform, and a predetermined number or more balls can be maintained due to the jackpot game.

Next, a modification in which the above embodiment is partially changed will be described.
(1) The number of jackpot rounds may be set to various round numbers such as any of 7R to 9R and 11R to 16R.
(2) The number of times of opening / closing the dummy in the middle board may be one or three or more times.
(3) The first grand prize opening device 13 may execute the opening / closing patterns A to F. Further, at least one of the opening / closing patterns A to F may be executed in cooperation by the first and second big prize opening devices 13 and 14. For example, the second grand prize opening device 14 executes the first round, and the first big winning mouth device 13 executes the center and last rounds.

  In addition, various modifications other than the disclosed items can be added and implemented without departing from the spirit of the present invention. Further, the present invention can be applied to various pachinko gaming machines such as a pachinko gaming machine provided with only one big winning opening as a big winning opening device.
