Description

  The present invention relates to a pachinko machine installed in a pachinko parlor.

  Currently, various types of pachinko machines are offered, and as one of them, a winning lottery using random numbers is performed when a game ball wins a winning prize opening, and it is determined whether or not to win For example, it is known that a winning lottery result is displayed after a symbol variation display is performed on a symbol display device such as a 7-segment display device or a liquid crystal display. When winning in the winning lottery, the normal mode is changed to the winning mode, and the game is performed under the number of rounds selected in the lottery. In the winning mode, opening of the attacker in each round releases the large winning opening that is closed in the normal mode, and most of the game balls are guided to the large winning opening on the inner surface of the attacker. You can get a game ball. Generally, since a player plays a game for the purpose of acquiring a game ball, it is an important factor for raising interest in the game to make the player interested in the hit mode.

  Against this backdrop, the pachinko machine profit side is undermined, for example by providing two start prize openings and increasing the chances of winning a lottery so that the pachinko machine provider can attract many players. The game has been developed within a range that is not devised (for example, Patent Documents 1 to 5). In a pachinko machine with two starting prize holes, when a game ball wins one of the starting prize holes, the round in the hit mode is more than the case where a game ball wins the other starting prize hole and a win occurs. The movement of the game balls launched on the board of the game board by making a difference in the number of game balls that can be obtained by the start winning opening where the game balls have won, such as selecting the number of rounds so that the number increases Interested in.

  In addition, most of the pachinko machines provided in recent years have a movable piece that can be opened and closed at the start prize opening, and if the winning lottery executed when the game ball passes through the through chucker, the movable piece will be released. This increases the winning rate of game balls. After the hit mode is completed, the movable piece is released for a longer time than the normal mode and the symbol variation time is shortened, and in the short time period, the winning rate of the game ball at the start winning opening is improved. By doing so, it is possible to efficiently display the variation of the symbols without reducing the player's ball.

  In this way, by providing a plurality of start winning openings, the opportunity to play a game in the hit mode is increased, or the opportunity to play a game without reducing the number of possessed balls can be increased by shifting to a short time section. It tends to provide a game characterized by the possibility that a player can acquire a larger amount of pachinko balls at least in a short period of time.

However, having the possibility of acquiring a large number of pachinko balls in a short period of time as described above makes the player have great interests, but on the other hand, the player's gambling is mischievous, and the soundness of the pachinko machine is It can be detrimental. For this reason, for example, when playing a game on a trial basis under the customs business law or voluntary restrictions of the manufacturer of a pachinko machine, the number of rounds in one hit mode is N times, 1 round M × N, where R is the maximum number of winnings in S, and S is the maximum number of gaming balls to be paid out when one gaming ball wins the big winning opening, and M is the winning probability per win Measures such as designing each value so as to satisfy the relationship of × R × S ≦ 12 are taken. For those with multiple start winning openings, if the number of rounds selected by the starting winning opening and the selection rate thereof are different, the maximum number of rounds selected at each starting winning opening is applied to N in the above formula. Therefore, when the selection rate of the number of rounds of each start winning opening and the number of rounds to be selected are the same, the average number of rounds selected at each starting winning opening is applied to N in the above formula.
JP 2006-55210 A JP 2006-34364 A JP 2005-342352 A JP 2005-342262 A JP 2007-159765 A

  However, if each value in the above formula is designed by changing the selection rate of the number of rounds or the number of rounds to be selected depending on the starting winning opening, the maximum number of rounds must be applied to the above formula. The number of game balls that can be obtained as a result of the game, even if the number of game balls that can be obtained through the starting winning opening must be different, as a result, must be reduced. There was no increase. However, if there is no difference in the number of game balls that can be obtained by the start winning opening, it will not be possible to make interest in the flow of game balls, and it will be difficult to make a difference depending on the skill of the player, so There is a disadvantage that it becomes unified and tired of games.

  The present invention has been made in consideration of the above-described problems. Even if the number of rounds selected at a plurality of start winning openings and the round number selection rate are the same, the game balls acquired by the player through the starting winning openings are as follows. An object is to provide a pachinko machine capable of making a difference in the number.

  In order to achieve the above object, the pachinko machine according to the present invention has a first start winning opening and a second starting winning opening provided separately, and the first start winning opening or the second start winning opening is provided. A movable piece that changes the winning rate of the game ball by opening and closing is attached to at least one of the starting winning ports of the game, and the gaming ball has won the first starting winning port or the second starting winning port The winning lottery is executed to determine whether or not to win, and the result of the winning lottery is displayed according to the type of symbols stopped after displaying the variation of the symbols. The lottery is executed, and after the round number lottery is executed, the large winning opening that is closed in the normal mode is shifted to the winning mode for each round, and the number of rounds determined by the round number lottery is changed. When the number of rounds is over, the winning mode is ended, and after the winning mode is ended, the mode is shifted to a short time interval, and in the short time interval, the opening time of the movable piece is longer than that other than in the short time interval. In the pachinko machine in which the variation time of the symbol is shorter than that in the time zone other than the short time interval, the randomness extracted by the lottery drawing when the game ball wins the first start winning opening and wins the win A numerical value is collated, and any one of a plurality of types of round numbers having different numbers of times is assigned to each of the random number values, and an end condition of the time-short interval or presence / absence of the time-short interval is set as the number of rounds for each random value. The first round number table assigned in an overlapping manner and the round when a game ball wins a prize at the second start winning opening and wins the winning Random values extracted by lottery are collated, and the same number of rounds as the number of rounds assigned in the first round number table is assigned to each of the random number values in the same ratio as the first round number table, and The same number of rounds as the number of rounds assigned in the first round number table have different selection rates for the same end condition in the short time interval, or the selection rates for the presence or absence of the short time interval differ, or the end in the short time interval Depending on the result of the round number lottery and the second round number table in which the end condition of the short time interval or the presence or absence of the short time interval is assigned to each of the random number values by overlapping with the round number so that the conditions are different The game control means for executing the game in the short time section is provided.

  The hit is composed of a normal hit that shifts to the hit mode and a probability change hit that shifts to the probability variation mode in which the winning probability of the hit is higher than the normal mode after the hit mode ends. Either the first symbol indicating that the winning per normal variation or the probability variation is won and the second symbol indicating that the winning per probability variation is displayed after the variation display of the symbol is stopped, the normal winning or the certain probability variation And a specific end condition is set as a condition that the number of symbol fluctuations reaches a predetermined number as the end condition of the short time section, and the first round number table and the second round number table In each of the random number values, either the normal hit or the probability change is assigned to be overlapped with the round number. In addition, a random number value assigned with a predetermined number of rounds among a plurality of types of round numbers is assigned with a random number value assigned with the normal hit and the specific end condition, and with a probability change and the specific end condition. For the random number value including both the random number value and the specific number of rounds assigned, the other one is more likely to have the probability variation and the second than the first round number table or the second round number table. The ratio of the random number value assigned by overlapping the specific end condition is increased, the specific round number is selected, and the random number value to which the normal end and the specific end condition are assigned or the probability variation and the specific end condition are When the assigned random number value is extracted, the first symbol is stopped and the specified end condition is less than the assigned random number value. If the random number value of is extracted preferably it is displayed by stopping the second symbol.

  According to the first aspect of the present invention, it is possible to change the number of game balls that can be acquired in the short time section by the start winning opening where the winning occurs, and the number of rounds and the number of rounds selected by a plurality of starting winning openings Even if the selection ratio is the same, the number of game balls acquired by the player can be differentiated by the start winning opening.

  According to the second aspect of the present invention, when a specific round is selected, it becomes difficult to discriminate whether the winning is a probable change or a normal win even if a short time interval is entered, and it is difficult for the player to stop the game. It becomes possible to do. Thereby, the operation rate of a pachinko machine can be raised.

  As shown in FIG. 1, the pachinko machine 10 includes a game board 11. A game area 11a is formed on the surface of the game board 11, and the launched game ball flows down the game area 11a. The game area 11a is provided with a first start winning opening (hereinafter referred to as “first starting opening”) 12, a second starting winning opening (hereinafter referred to as “second starting opening”) 13, and a through chucker 14. Yes. When a game ball wins a prize in the first start port 12 or the second start port 13, a predetermined number of game balls determined in advance are paid out as a prize ball. The first start port 12 and the second start port 13 are arranged one above the other, and the second start port 13 is disposed below the first start port 12. A pair of movable pieces 13 a having a base end portion pivotally supported on a shaft extending in the front-rear direction is attached to the second start port 13. The movable piece 13a is normally located at a closed position where the tip ends approach each other, and when the winning lottery executed when the game ball passes through the through chucker 14, the movable piece 13a rotates to the open position where the tip ends separate. To do. When the movable piece 13a is rotated to the open position, the game ball is guided into the second starting port 13 on the inner surface thereof, so that the game to the second starting port 13 is performed more than when the movable piece 13a is positioned at the closed position. The winning rate of the ball increases. The opening time of the movable piece is 0.5 seconds for each opening, except for the short time interval described later, and 2 seconds for the short time interval. When the movable piece 13a is located at the closed position, the gap between the movable pieces 13a is covered by the first starting port 12, so that the second starting port 13 has a game only when the movable piece 13a rotates to the open position. You can win a ball.

  When a game ball wins the first or second starter 12 or 13, a winning lottery for determining a winning or losing is performed. When winning, the lot number lottery is performed, and the number of rounds in the winning mode, either normal hit or per probability change, the presence / absence of the short time section after the end of the winning mode, and the end condition of the short time section are determined. When winning in the normal winning mode, the mode is shifted to only the winning mode, and when winning per probable change, the mode is shifted to the probability variation mode following the winning mode. In the probability variation mode, the winning probability is higher than in the normal mode.

  In the winning mode, a game is played under the number of rounds determined by the round number lottery. In each round, the attacker 15 provided below the game area 11a is released once. A large winning opening (not shown) is provided in the back of the attacker 15, and when the attacker 15 is opened, most of the game balls flowing down the gaming area 11 a are guided to the large winning opening on the inner surface and receive a large number of winning balls. Can be obtained. Then, when 10 game balls are won in the big winning opening or when 30 seconds have elapsed from the start of the round, the attacker 15 is closed and one round is finished, and when the number of rounds determined by the round number lottery is finished, the winning mode is finished. .

  A center accessory 16 is provided in a substantially central portion of the game area 11a. A liquid crystal display 17 is incorporated in the center accessory 16. On the liquid crystal display 17, symbols 18 arranged side by side in three rows are displayed. The symbol 18 in each column is composed of three types of “blue”, “red”, and “pink”. When a game ball wins the first or second start port 12, 13 during the normal mode or the probability variation mode, the variation display of the symbol 18 is started, and the symbol 18 scrolls from top to bottom. Then, the symbols 18 are sequentially stopped one by one (in order of left → right → middle), and when all symbols 18 are stopped, the symbols 18 of the same color are aligned or the color arrangement of the symbols 18 is a specific arrangement. (Hereinafter “chance”) will be a hit.

  At this time, when all the blue symbols 18 are hit, the number of rounds of the hit mode is 14 rounds, the end condition of the short time section is up to 100 fluctuations of the symbols 18, and either the normal hit or the probability change is given. . Also, when the red symbols 18 come together, the number of rounds in the winning mode is 16 rounds, and the winning condition is determined until the end condition of the short time section is won. Furthermore, when the pink symbols 18 are all won, the number of rounds in the hit mode is 14 rounds, and the winning condition is determined until the end condition of the short time section is won. Also, when the chances are matched, the number of rounds in the winning mode is 2 rounds, and the end condition of the short time section is won or the short time section is not found and the probability change is confirmed.

  At the bottom of the pachinko machine 10, a launch handle 19 that rotates when a game ball is launched into the game area 11a and a tray 20 from which a prize ball is paid out are provided.

  As shown in FIG. 2, the pachinko machine 10 includes a control unit (game control means) 30. The control unit 30 controls the overall operation of the pachinko machine 10 such as the execution of games in each mode and a short time interval, the display control of the liquid crystal display 17 in accordance with the game control program and image data stored in the memory 31.

  The first start sensor 32 a detects the game ball that has entered the first start port 12, and the second start sensor 32 b detects the game ball that has entered the second start port 13. The through sensor 33 detects a game ball that has passed through the through chucker 14. Note that the through-chucker 14 only passes the game ball and does not win the game ball, so the prize ball is not paid out.

  The prize ball payout device 34 is activated when a game ball wins the first or second start port 12 or 13, and pays out a specified number of game balls as a prize ball.

  The game ball launching device 35 launches game balls one by one into the game area 11a when the firing handle 19 is rotated. The launch strength of the game ball is adjusted according to the amount of rotation of the launch handle 19. Note that the control by the control unit 30 is not performed on the game ball launching device 35, and the launch control of the game ball is performed by the launch control board included in the game ball launching device 35.

  The attacker drive device 36 opens and closes the attacker 15 for each round in the hit mode.

  The winning lottery unit 38 receives a signal input from the control unit 30 when a game ball wins the first or second starting port 12 or 13, and performs a winning lottery using an electronic random number. Determine the loss. In the winning lottery, the random number extracted at the time of the lottery is compared with a winning determination table, and it is determined whether the extracted random number is a winning random number or not. The hit determination table is composed of a normal table used in the normal mode and a probability variation table used in the probability variation mode. In the probability variation table, the winning probability of winning is set higher than that of the normal table. However, the probability variation table has more random numbers.

  The round number lottery unit 39 performs a lot number lottery using an electronic random number in response to a command input from the control unit 30 when winning a win, and determines the number of rounds in the hit mode, the normal win or the probable change Either the presence / absence of a short time interval or the termination condition of the short time interval is determined. The round number lottery unit 39 includes a random number generation circuit and a random number sampling circuit, and samples one of 65536 random values from 0 to 65535 generated by the random number generation circuit by the sampling circuit, and samples the random number Are compared with the first round number table 40 or the second round number table 41 to determine the number of rounds. The first round number table 40 is used for collation of random numbers when a game ball wins at the first starting port 12 and a winning occurs, and the second round number table 41 is used for the second starting port 13. When a game ball wins and a winning occurs, it is used for collation of random numbers. The random number may be generated by hardware.

  As shown in FIG. 3, in the first round number table 40, each of 65536 random numbers from 0 to 65535 is assigned one of a plurality of types of round numbers having a different number of times, and the end of the short time interval Whether or not there is a condition or a short time interval, either a normal hit or a probable change, and the type of winning symbol for displaying the hit is assigned to overlap the number of rounds. For this reason, when the round number lottery is performed, each of the above conditions is determined at a time.

  Specifically, the random number value from 0 to 21999 has 14 rounds (specific number of rounds), the hit type is normal, and the end condition of the short time section is “the number of changes in the symbol is 100 times (predetermined number) The blue symbol (the first symbol) is assigned to the winning symbol until “has reached (specific end condition)”.

  In addition, the random number value of 22000 to 43999 is assigned 16 rounds, the type of winning is probable, the end condition of the short time section is “until winning”, and the winning symbol is assigned red.

  In addition, the random number value of 44000-50999 has 14 rounds (number of specific rounds), the hit type is probable, the end condition of the short time section is “until winning”, and the win symbol is pink (2nd Design) is assigned.

  In addition, the random number value of 51000 to 57999 has 14 rounds (number of specific rounds), the hit type is definitely variable, and the end condition of the short time section is “until the number of symbol fluctuations reaches 100 times (predetermined number)” (Specific end condition) ”, blue (first symbol) is assigned to the winning symbol.

  In addition, the random number value of 58000 to 59999 has a round number of 2 rounds, the type of hit is probable, the end condition of the short time interval is “until wins”, and a chance symbol is assigned to the win symbol.

  In addition, the random number values of 60000 to 65535 have a round number of 2 rounds, a hit type is probable, a short time interval is not provided, and a chance symbol is assigned to the win symbol.

  As shown in FIG. 4, in the second round number table 41, each of 65536 random numbers from 0 to 65535 is assigned one of a plurality of types of round numbers having a different number of times, and the end of the short time interval Whether or not there is a condition or a short time interval, either a normal hit or a probable change, and the type of winning symbol for displaying the hit is assigned to overlap the number of rounds. For this reason, when the round number lottery is performed, each of the above conditions is determined at a time. Further, in the second round number table 41, 2, 14, and 16 rounds, which are the same round numbers as the numbers assigned in the first round number table 40, are assigned to the random number values at the same ratio as in the first round number table 40. Assigned.

  Specifically, the random number value from 0 to 21999 has 14 rounds (specific number of rounds), the hit type is normal, and the end condition of the short time section is “the number of changes in the symbol is 100 times (predetermined number) The blue symbol (the first symbol) is assigned to the winning symbol until “has reached (specific end condition)”.

  In addition, the random number value of 22000 to 43999 is assigned 16 rounds, the type of winning is probable, the end condition of the short time section is “until winning”, and the winning symbol is assigned red.

  In addition, the random number value of 44000 to 53999 has 14 rounds (number of specific rounds), the hit type is probable, the end condition of the short time section is “until winning”, and the win symbol is pink (2nd Design) is assigned.

  In addition, the random number value of 54000 to 57999 has a round number of 14 rounds (specific round number), the hit type is definitely variable, and the end condition of the short time section is “until the number of symbol fluctuations reaches 100 times (predetermined number of times)” (Specific end condition) ”, blue (first symbol) is assigned to the winning symbol.

  In addition, the random number value of 58000 to 65535 has 2 rounds, the hit type is probable, the end condition of the short time section is “until winning”, and the win symbol color is assigned a chance. .

  As described above, in the first round number table 40 and the second round number table 41, the numbers of random numbers assigned to the respective round numbers are the same, that is, the selection rates of the respective round numbers are the same. . However, the same round number in the first round number table 40 and the second round number table 41, that is, the selection rate of the same end condition in the short time interval between two rounds, 14 rounds, and 16 rounds of each table These are assigned so as to overlap with the number of rounds so that the selection rates for the presence or absence of the short time interval are different or the end conditions in the short time interval are different.

  Specifically, in the first round number table 40, the random number value of 44000-50999 is assigned 14 rounds and the end condition of the short time section is “until winning”. In the 2-round number table 41, the end condition of the short time section is assigned to the random number value of 44000 to 53999 and the round number is 14 rounds, and the end condition of the short time section is assigned in each table. The winning conditions are the same and the end conditions are the same, but the selection rates are different.

  Similarly, in the first round number table 40, “until the number of symbol fluctuations reaches 100” is assigned to the random number values 51000 to 57999 as the end condition of the short time interval with 14 rounds. On the other hand, in the second round number table 41, the random number value of 54000 to 57999 is assigned with the number of rounds of 14 rounds and the termination condition of the short time interval as “until the number of symbol variations reaches 100”. In each table, the end condition of the short time section is “until the number of symbol variations reaches 100”, and the end conditions are the same, but the selection rates are different.

  Furthermore, in the first round number table 40, the random number value of 58000 to 59999 is assigned 2 rounds and the end condition of the short time section is “until winning”, whereas the second round number In Table 41, the random number value of 58000 to 65535 is assigned the number of rounds of 2 rounds, and the end condition of the short time section is assigned “until winning”. In each table, the end condition of the short time section is a hit. The winning conditions are the same and the end conditions are the same, but the selection rates are different.

  In addition to the above, in the first round number table 40, the random number value of 60000 to 65535 is assigned 2 rounds and “none” is assigned to the time interval, whereas in the second round number table 41, the time reduction It always shifts to the section, and the presence or absence of the short time section is different in each table.

  As described above, in the first round number table 40 and the second round number table 41, 14 rounds, which are a predetermined number of rounds, among the plural types of round numbers 2, 14, and 16 are assigned. Random numbers include both random values assigned with specific end conditions for normal and short time intervals, and random values assigned with specific end conditions for probability variation and short time intervals. ing. From this, when 14 rounds are selected and a specific end condition is selected, it is not possible to identify whether the winning is normal or probable, and the player can have a sense of expectation for probable it can.

  Further, for the random number value to which the number of 14 rounds is assigned, the first round number table 40 increases the proportion of random number values assigned by overlapping the probability variation and specific end condition more than the second round number table 41. In the second round number table 41, since the number of random number values to which “until the winning is true” that is the end condition of the probability variation per and short time interval is increased, the second round number table 41 even if 14 rounds are selected. The first round number table 40 is more likely to win the chance that the symbol is displayed in blue, and the second round number table 41 is more likely to win the chance that the symbol is displayed in pink. And if the winning symbol is pink, the probability winning is fixed, so when winning in the first round number table 40, that is, when the game ball wins the first starting port 12 and wins the winning, The chance that it is not possible to identify whether the winning ball is won in the normal hit or the probable change is greater than when the winning ball is won in the starting port 13 of the second win. Thereby, when a game ball wins at the first start port 12 and wins, the player's sense of tension can be enhanced more than when a game ball wins at the second start port 13 and wins. .

  The open lottery unit 42 is operated in response to the game ball being detected by the through sensor 33. The open lottery unit 42 determines whether to open the movable piece 13a of the second starting port 13 by performing an open lottery using an electronic random number. When the open lottery is won, the control unit 30 opens the movable piece 13a for 0.2 seconds except for the short time interval and for 2 seconds in the short time interval.

  The lose symbol lottery unit 43 is activated when a game ball is won at the first start port 12 or the second start port 13 and a lottery is performed, resulting in a loss. The losing symbol lottery unit 43 performs a losing symbol lottery using an electronic random number, and determines a combination of symbols to be stopped when the winning lottery is lost. The lottery result is fed back to the control unit 30, and the control unit 30 stops the symbol that is variably displayed according to the lottery result.

  Next, the flow of the game when winning in the pachinko machine 10 configured as described above will be described.

  As shown in FIG. 5, first, a game in the normal mode is performed. The game balls launched one by one by the turning operation of the launch handle 19 flow down the game area 11a. The game ball that has flowed down the game area 11a wins the first start port 12, passes through the through chucker 14, or is collected as an out ball. When the game ball passes through the through chucker 14, an open lottery is performed. When the open lottery is won, the movable piece 13a of the second start port 13 is opened, and the second start port 13 can win a game ball at this time. When a game ball enters the first start port 12 or the second start port 13, a specified number of award balls are paid out.

  In addition, when a game ball wins at the first start port 12 or the second start port 13, a winning lottery is executed and a win or a loss is determined. If the winning lottery is lost, the lost symbol lottery is performed, the symbol variation display is performed, the combination of the lost symbols is displayed, and the process ends. If the winning lottery is won, the control unit 30 selects the first round number table 40 or the second round number table 41 as the table selection process.

  The control unit 30 selects the first round number table 40 when a winning game ball is won at the first starting port 12 and wins when the winning ball is won at the second starting port 13. In this case, the second round number table 41 is selected, and a table selection command indicating the type of the selected table is input to the round number lottery unit 39. In response to the table selection command, the round number lottery unit 39 performs the round number lottery using the selected table.

  When the number-of-rounds lottery is performed, the number of rounds in the winning mode, either per probability change or normal winning, whether or not there is a short time section, the end condition of the short time section, and the type of winning symbol are determined simultaneously. The result of the round number lottery is written in the RAM area of the memory 31. The control unit 30 performs processing associated with symbol change / stop, processing in the hit mode, and game execution processing in the short time interval while referring to the result written in the memory 31.

  When the round number lottery ends, the symbol change display is started, the symbol or chance chance of the color determined in the round number lottery stops, and the mode is changed to the winning mode. In the win mode, a game with the number of rounds determined by the lot number lottery is performed. When the number of rounds determined by the round number lottery ends, the hit mode ends.

  When it is decided to shift to the short time section in the lot number lottery, the short time section is shifted to after the end of the hit mode. In the short time section, the open time of the movable piece 13a becomes longer and the symbol fluctuation time becomes shorter when the open lottery is won than in the time other than the short time section. As a result, the winning rate of game balls to the second starting port 13 increases and the number of prize balls increases, so that the game can be performed without reducing the number of game balls on hand, and the game can be efficiently advanced. Can do. When the end condition determined in the round number lottery is satisfied, the short time interval ends.

  In the above embodiment, 2, 14, and 16 rounds are set in the first round number table 40 and the second round number table 41, but the number of rounds to be set may be appropriately set.

  In the above-described embodiment, the selection rate of the same end condition of the short time section and the presence / absence of the short time section are different in the first round number table 40 and the second round number table 41. The end condition of the short time section in the other table may be made more advantageous than the one table.

  In the above embodiment, the hit type is composed of the normal hit and the probability change, but the hit type may be one.

  In the above-described embodiment, a pachinko machine that displays a variation of a symbol using a liquid crystal display has been described as an example. However, other embodiments such as a pachinko machine that displays a variation of a symbol using a reel that rotates by driving a motor are used. You may apply this invention to the pachinko machine which displays the result of a lottery.

A movable piece for changing the winning rate of the game ball is attached, and when a game ball wins the first starting winning port or the second starting winning port, a winning lottery is performed to determine whether or not to win The result of the winning lottery is displayed according to the type of the symbol that has been stopped after the symbol change display, and if the winner is won, the round number lottery is executed, and after the round number lottery is executed in the normal mode. The winning mode that is closed is shifted to a winning mode for each round, and the winning mode is ended when the number of rounds determined by the round drawing is completed. When the winning mode is over, the shift is made to the time-shortening section, and in the time-shortening section, the opening time of the movable piece is longer than when it is other than the time-shortening section, and the symbol variation time is other than the time-shortening section. In pachinko machines that are shorter than
Random numbers extracted in the lot number lottery when a game ball wins the first start winning opening and wins the winning match are collated, and any one of a plurality of types of round numbers having different numbers of times is checked. A first round number table that is assigned to each of the numerical values, and the end condition of the short time interval or the presence or absence of the short time interval is assigned to each of the random number values by overlapping with the round number;
The random number value extracted in the lot number lottery when the game ball wins the second start winning opening and wins the winning match is collated, and the same number of rounds assigned in the first round number table The number of rounds is assigned to each of the random values at the same ratio as the first round number table, and the same number of rounds as the number of rounds assigned in the first round number table is set to the same end condition of the short time interval. Each of the random number values includes the end condition of the short time interval or the presence or absence of the short time interval so that the selection rate is different or the selection rate of the presence or absence of the short time interval is different or the end condition in the short time interval is different. A second round number table assigned in duplicate with the round number;
A pachinko machine comprising game control means for executing a game in the short time interval according to a result of the lot number lottery. The hit is composed of a normal hit that shifts to the hit mode, and a probability change hit that shifts to the probability variation mode in which the winning probability is higher than the normal mode after the hit mode ends, and the normal hit Alternatively, either the first symbol indicating winning per probability variation or the second symbol indicating winning per probability variation is stopped after displaying the variation of the symbol, and the normal symbol or per probability variation is won. And a specific end condition is set as a condition that the number of times the symbol has reached the predetermined number of times as the end condition of the short time interval,
In the first round number table and the second round number table, each of the random number values is assigned with either the normal hit or the probability variation overlapping with the round number, and among the plural types of round numbers The random number value assigned with a predetermined number of specific rounds includes both the random value assigned with the normal per and the specific end condition, and the random number value assigned with the probable change and the specific end condition, and As for the random number value to which the specific number of rounds is assigned, the random number value in which the other one of the first round number table and the second round number table is assigned the probability variation and the specific end condition redundantly. Increase the proportion of
The first symbol is stopped when the specific round number is selected and the random number assigned with the normal hit and the specific end condition or the random number assigned with the probability variation and the specific end condition is extracted. The pachinko machine according to claim 1, wherein when a random value other than the random value assigned with the specific end condition is extracted, the display of stopping the second symbol is displayed.
