Description

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

  In recent pachinko machines, a display device is provided at the center of the game board, and an openable door called a large attacker is arranged at the bottom. When the game ball passes through the start winning opening and wins, a plurality of types of symbols displayed on the display device are variably displayed. Inside the pachinko machine, a lottery based on the winning timing is executed, and when the lottery is won, the gaming state shifts from the normal game to the big hit game. In the jackpot game, a large attacker opens and closes, and a large number of game balls win during the open period.

  In a jackpot game, a game in which a large attacker is released usually lasts up to 16 times. The release period from the satisfaction of the condition for the large attacker to open until the end condition is satisfied, such as 30 seconds have passed or 10 game balls have been won (the large attacker may open and close several times during this period) Is called a round. In order to move from one round to the next, it is necessary to satisfy a predetermined continuation condition. A specific area called a V zone and a special winning opening are provided inside the large attacker. Usually, it is a continuation condition that the game ball passes through the V zone.

Moreover, in a certain kind of pachinko machine, when a particular symbol is a big win, the winning probability for the big win is set high. A gaming state with a high jackpot winning probability is called a probability variation mode, and a gaming state with a low jackpot winning probability is called a normal mode. Among symbols that are jackpots, a symbol that shifts from the normal mode to the probability variation mode (hereinafter referred to as probability variation mode) after the jackpot is terminated is called a probability variation symbol, and a symbol that maintains the normal mode is termed a normal symbol. Furthermore, there are also known pachinko machines that continue the probability variation mode after the next jackpot game is completed even if the next jackpot symbol is a normal symbol when the probability variation symbols are aligned and shifted to the jackpot game (for example, patents). Reference 1).

  By the way, since most of the payout of game balls is performed in jackpot games, the player's interest is exclusively directed to jackpot games. As described above, in the conventional pachinko machine, since the probability variation mode is adopted, the next jackpot can be allocated in a short time.

  However, even if the jackpot is allocated with a probabilistic design, the maximum number of rounds included in one jackpot game is fixed, so it was not possible to make a difference in the number of game balls paid out in one jackpot game. . In other words, even if the conventional pachinko machine game can change the jackpot time interval such as the long time to win the next jackpot, it will change the number of game balls paid out in the jackpot game itself I could not. As a result, there was a problem that a series of games became monotonous.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a gaming machine that makes a difference in the number of game balls to be paid out in a single jackpot game.

  The present invention will be described below. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment.

  The gaming machine according to the present invention is capable of providing display means (60) in which a plurality of types of symbols are variably displayed when a variable condition is satisfied, and a large game value can be given compared to a normal game or the normal game. A game management means (31) that selectively executes a jackpot game including a first jackpot game and a second jackpot game that has a higher game value than the first jackpot game, and determines whether it is a jackpot or lose When the lottery means (31), the lottery result of the lottery means (31) is a big hit, the winning mode determining means (31) for determining the winning mode to be displayed on the display means (60), and the winning mode determination When the winning mode determined by the means (31) is the first mode, the game management unit (31) is caused to execute the first big win game (A), and the winning mode determining unit (3) When the winning mode determined in 1) is the second mode, the game management means (31) is caused to execute the second jackpot game (B), and a predetermined number of times since the next jackpot game. In the future jackpot game, even if the winning mode is the first mode, the game management means (31) executes the second jackpot game (B) instead of the first jackpot game (A). And a control means (31).

  According to the gaming machine of the present invention, it is possible to execute two types of jackpot games in which weight is given to the game value that can be given in one jackpot game. In the first win, the type of jackpot game is selected depending on whether the winning mode is the first mode or the second mode. That is, in the first win, the winning mode is associated with the game value that can be acquired by the jackpot game. Then, the type of the first jackpot game is partially reflected in the type of the next jackpot game. That is, if the first game is the second jackpot game, the second jackpot game is the second jackpot game even if the winning mode of the second jackpot game is the first mode. As a result, the game value that can be given in the jackpot game can be changed, so that the fun of the game is improved. If the game control means causes the game management means to execute different jackpot games or change the contents of the jackpot game a predetermined number of times according to the winning mode, the game control means counts a flag or a predetermined number of times according to the winning mode. It also includes generating a value and selectively executing the game according to the flag or count value by the game management means. Here, for example, a pachinko machine using a game ball corresponds to the gaming machine.

  In the gaming machine described above, the jackpot game management means (31) manages a single jackpot game by dividing it into a plurality of rounds, and determines the number of rounds that can be executed in one jackpot game. It is preferable to manage the progress of the jackpot game by setting the number of rounds of the second jackpot game (B) to be greater than the number of rounds of the first jackpot game (A). According to the present invention, it is possible to select and execute a jackpot game having a different number of rounds depending on the winning mode, and when shifting to the second jackpot game, in the future jackpot game from the next jackpot game a predetermined number of times, The second jackpot game is executed regardless of the type of aspect. As a result, the game value that can be given in the future jackpot can be determined with the current jackpot, and the player's expectation can be maintained for a long time. More specifically, the jackpot game management means (31) terminates the jackpot game when the count result matches a predetermined reference value with counting means for counting the number of rounds in the jackpot game. It is preferable to include ending means and setting means for setting a larger reference value in the second jackpot game (B) than in the first jackpot game (A).

  In the gaming machine described above, the jackpot game management means (31) manages by setting a continuation condition as to whether or not the next round can be executed after a round in which one jackpot game is divided into a plurality of rounds. In the second jackpot game (B), a process of relaxing the continuation condition than the first jackpot game (A) may be executed. According to this invention, it is possible to give a difference to the game value that can be given due to the difference in the continuation condition of the round. Note that the process of relaxing the continuation condition includes not imposing a condition on the continuation of the round.

  In the gaming machine described above, the game control means (31) stores a plurality of types of times as the predetermined number of times, and the next jackpot after the next time is the number selected from the plurality of types of times according to a predetermined rule. It is preferable to control the game management means (31) so that the game is the second big hit game (B). According to the present invention, since the second jackpot game can be further subdivided and managed, the variety of games can be further improved.

Here, the game management means (31) manages a plurality of game states having different game values to which the second jackpot game (B) can be given, and the game control means (31)
The game control means (31) manages the second mode of the winning mode divided into symbol types and manages the types of symbols included in the second mode of the winning mode and the plurality of gaming states. Referring to the storage means (35) for storing information, the specifying means (31) for specifying the type of symbol of the winning mode determined by the winning mode determining means (31), and the storing means (35), It is preferable to include a game state management means (31) for controlling the game management means so as to be in the gaming state corresponding to the type of symbol specified in the second jackpot game. According to this invention, the gaming state of the second jackpot game can be changed according to the jackpot symbol.

Further, the game management means (31) manages a plurality of game states having different game values to which the second jackpot game (B) can be given, and the game control means (31)
The game control means (31), when starting the second jackpot game (B), a game state lottery means (31) for determining one game state from the plurality of game states by lottery, and the game state lottery It is preferable to include a game state control means (31) for controlling the game management means (31) so as to be in the gaming state of the lottery result of the means (31). According to this invention, the game state of the second jackpot game can be changed by lottery.

Further, the game management means (31) manages a plurality of game states having different game values to which the second jackpot game (B) can be given, and the game control means (31)
The game control means (31) includes a payout rate calculating means (31) for calculating a payout rate, a storage means (35) for storing the payout rate and the plurality of game states in association with each other, and the storage. With reference to the means (35), it is preferable to include a game state control means (31) for controlling the game management means (31) so as to be in the gaming state corresponding to the calculated payout rate. According to this invention, it is possible to change the gaming state of the second jackpot game according to the pitch rate.

  In the gaming machine described above, the lottery means (31) can switch the jackpot winning probability from a low probability to a high probability with a winning rate higher than the low probability, and the current jackpot game is the lottery game. Regardless of whether the first jackpot game or the second jackpot game, the lottery so that the winning probability is set to the high probability by a predetermined number of high-probability lotteries after the jackpot game is ended, depending on the winning mode. It is preferable to include a probability control means (31) for controlling the means (31). According to the present invention, the jackpot lottery probability can be changed independently of the jackpot game type. That is, since the game value that can be acquired by one jackpot and the time interval at which the jackpot occurs are changed independently, the variety of games is further improved.

  Here, the probability control means (31) includes the first mode and the second mode as the winning mode in which the lottery after the jackpot game is finished has the high probability. When the type and the lottery probability are stored in association with each other, the stored content is referenced to determine whether the probability is the high probability or the low probability, and when the winning mode is the first mode, The winning mode and the high-probability lottery number are stored in association with each other so that the high-probability lottery number is larger than that in the case where the winning mode is the second mode. Then, it is preferable to control the lottery means so that the high probability is obtained by the number of times of high probability lottery after the jackpot game ends. According to the present invention, when the winning mode is the second mode, the second jackpot game having a large game value that can be given is executed, but the winning probability of the second mode is set low, so a series of games The fluctuation range of the game value given in can be suppressed. More specifically, the probability control means (31) includes the first symbol and the second symbol as the winning symbols that make the lottery a predetermined number of times after the end of the jackpot game as the high probability. In this way, the type of winning symbol and the lottery probability are stored in association with each other, and it is determined whether the high probability or the low probability is referred to with reference to the stored content, and the winning symbol is the first symbol. If the winning symbol is, the winning symbol and the predetermined number of times are stored in association with each other so that the predetermined number of times of performing the lottery with the high probability is larger than that in the case where the winning symbol is the second symbol. It is preferable to control the number of lotteries with a high probability after the jackpot game is finished with reference to the stored contents.

  In the gaming machine described above, the game management means (31) manages a plurality of game states having different game values to which the second jackpot game can be given, and the lottery means (31) The lottery can be executed by switching the winning probability from a low probability to a high probability having a higher winning rate than the low probability, and the lottery with the higher probability is executed as the game value that can be given in the second big hit game (B) increases. The plurality of gaming states and the high probability lottery times are stored in association with each other so that the number of high probability lottery times to be reduced is smaller, and the current jackpot game is the second jackpot game (B). With reference to the stored content, the lottery player performs the high-probability lottery for the number of times of the high-probability lottery corresponding to the gaming state after the second jackpot game (B) is completed. It is preferable to provide probability control means for controlling (31) and (31). According to the present invention, when the game value that can be given in the jackpot game is increased, the number of lotteries with high probability is reduced, so that the fluctuation range of the game value given to the player can be suppressed.

  In the gaming machine described above, the symbol variation time for variably displaying the symbol on the display means (60) includes a normal time and a short time shorter than the normal time, and the type of winning mode and the symbol variation time are set as follows. The variable display times corresponding to the short time are stored in association with each other, and the symbol variation time is set to the variable display times corresponding to the winning symbol after the jackpot game is completed with reference to the stored content. It is preferable to include display control means (31) for controlling the display means (60) so that the time is short. According to the present invention, when the game value that can be given in the jackpot game increases, the number of times of variable display in a short time is reduced, so that the fluctuation range of the game value given to the player per unit time can be suppressed. More specifically, the type of the winning symbol is stored in association with the number of variable displays in which the symbol variation time is the short time, and the jackpot game is completed with reference to the stored content. What is necessary is just to have display control means (31) for controlling the display means (60) so that the symbol variation time becomes the short time later the number of times corresponding to the winning symbol.

  In the gaming machine described above, the game management means (31) manages a plurality of game states having different game values to which the second jackpot game can be given, and the display means (60) performs the symbol variation time. In the second jackpot game (B), there are a normal time and a short time shorter than the normal time, and the symbol variation time is divided into the normal time and the short time. The plurality of gaming states and the variable display count for the short time are stored in association with each other so that the greater the game value that can be granted, the smaller the variable display count for the short symbol change time. When the current jackpot game is the second jackpot game (B), the stored content is referred to and the game state is supported after the second jackpot game (B) is completed. It is preferable to that provided with the display control means only variable display times the symbol variation time to execute a process of controlling the display means so as to short the (31).

  In the gaming machine described above, the game management means classifies game value as at least one of the number of rounds included in one jackpot game or the predetermined number of times that the second jackpot game is executed in the future jackpot game. It is preferable that the second big hit game is managed by dividing it into the plurality of game states as an element to be performed. According to the present invention, since at least one of the number of rounds and the number of times the second big hit game is continued is used as an element for dividing the game value, the second big hit game can be subdivided and managed.

  In the gaming machine described above, the symbols include one or more types of first symbols and one or more types of second symbols, and the display means (60) displays a plurality of symbols on which the symbols are variably displayed. An area is provided, the winning mode is determined by the symbols displayed in the plurality of symbol display areas, and the winning mode determining means (31) is a case where the lottery result of the lottery means (31) is a big hit In addition, it is preferable that a winning symbol to be displayed in the plurality of symbol display areas is determined, and in the first mode of the winning mode, the winning symbol is the first symbol.

  According to the present invention, it is possible to provide a gaming machine capable of making a difference in the gaming value paid out in a single jackpot game.

  FIG. 1 is a plan view showing a game board which is a main part of a pachinko machine according to an embodiment of the present invention. In the pachinko machine 1, the game board 10 is fitted into an outer frame (not shown). The game ball 2 is launched by a launching device (not shown), and is released along the rail 2 to the upper part of the game board 10.

  An electric tulip 11 is provided at the center of the game board 10. The electric tulip 11 includes a pair of blades and an open solenoid. When the opening solenoid is driven, the pair of blades can be opened and closed. In addition, a start winning opening is provided inside the electric tulip 11, and when the game ball 2 passes the start winning opening, a special symbol displayed on the display device 60 is variably displayed. The display device 60 may be any device that can display an image. For example, a liquid crystal display device, a cathode ray tube monitor, or the like is applicable.

  FIG. 2 shows an example of a display screen displayed on the display device 60. The display screen is provided with five special display areas 60A for displaying special symbols. In addition, four holding ball display areas 60C indicating the number of holding balls are provided at the top of the display screen. In the pachinko machine 1, the special symbol displayed in the special display area 60A is variably displayed each time it passes through the start winning opening. In this example, eight numbers from 1 to 8 are adopted as special symbols. When the game ball 2 passes the start winning opening during the period in which the special symbol is variably displayed, the reserved ball display area 60C is lit in order from the left. When a certain variable display is finished and the next variable display is started, one of the on-hold holding ball display areas 60C is turned off sequentially from the right. That is, the number of variable displays is held. However, the upper limit of the number of times of holding is 4, and the number of times of holding does not change even if the game ball 2 passes through the start winning opening in a state where the holding ball display area 60C is all lit.

  A left gate 12 and a right gate 13 are provided on the left and right of the display device 60 shown in FIG. Even if the game ball 2 passes the left / right gate 12 or 13, the game ball 2 will not be paid out, but the normal symbol displayed in the normal display area 60B provided at the lower right of the display screen shown in FIG. Becomes variable display. In this example, “O” and “X” are adopted as normal symbols. And if it becomes "(circle)" in the state which variable display stopped, the electric tulip 11 will open only for the predetermined time. If the game ball 2 passes through one of the left / right gates 12 or 13 while the normal symbol is variably displayed, the reserved ball display area 60D is lit in order from the top. When a certain variable display is completed and the next variable display is started, one of the on-hold holding ball display areas 60D is turned off sequentially from the bottom. That is, the number of times of variable display of normal symbols is reserved. However, the upper limit of the number of holding times is 4, and even if the game ball 2 passes the left / right gates 12 or 13 in a state where all the holding ball display areas 60D are lit, the number of holding times does not change.

  Further, an upper left winning port 14 and a lower left winning port 16 are provided on the left side of the electric tulip 11, and an upper right winning port 15 and a lower right winning port 17 are provided on the right side of the electric tulip 11. When the game balls 2 win the prize holes, a predetermined number of game balls 2 are paid out.

  In addition, a large attacker 20 is provided below the electric tulip 11. Inside the large attacker 20, there are a large winning opening and a specific area called a V zone in the large winning opening. The large attacker 20 opens and closes during the big hit game and closes during the normal game. The nails arranged on the game board 10 are arranged to guide the game ball 2 to the large attacker 20. Accordingly, when the large attacker 20 opens, a large number of game balls 2 wins. The maximum number of times that the large attacker 20 opens and closes with one big hit is determined in advance. The large attacker 20 closes after 30 seconds have elapsed since it opened or when 10 game balls 2 have won. Further, when the large attacker 20 is opened, it is possible to win in the V zone or the large winning opening. However, at least one game ball 2 winning in the V zone is a condition for the large attacker 20 to open next.

  In this example, when three or more of the same special symbols displayed in the special display area 60A are arranged, the gaming state shifts from the normal game to the jackpot game. The jackpot game of this embodiment consists of a plurality of rounds. A round is a unit of a game in which the jackpot game is subdivided. For example, one round is a period from when the condition that the large attacker 20 opens to satisfy and the closing condition to satisfy the closing condition. To do.

  In the jackpot game of the present embodiment, the first mode having two modes can execute a maximum of 10 rounds per jackpot. In the following description, the first mode is referred to as jackpot game A (first jackpot game). In the second mode, a maximum of 16 rounds can be executed in one jackpot game. In the following description, the second mode is referred to as jackpot game B (second jackpot game). The game balls 2 that have not won a prize are discharged as out balls from the out port 30 provided in the lower part of the large attacker 20.

  Next, with reference to FIG. 3, the jackpot game employed in the pachinko machine 1 of the present embodiment will be described. As shown in FIG. 2A, the pachinko machine 1 has 10 rounds of jackpot game A when the symbols “1”, “2”, “4”, “5”, “6”, “8” are aligned. Is executed once. When the symbol “3” is completed, the jackpot game B of 16 rounds is executed until the jackpot for two times, and when the symbol “7” is prepared, the jackpot game B is executed until the jackpot for four times. . Since the jackpot game B has a larger number of rounds than the jackpot game A, the payout amount of the game balls 2 is increased. That is, the jackpot game B has a greater game value that can be given to the player than the jackpot game A.

  FIG. 2B shows an example of the transition of the jackpot game. For example, when the first jackpot symbol is “2”, the jackpot game is A, and when the second jackpot symbol is “4”, the jackpot game is A. On the other hand, if the first jackpot symbol is “3”, the jackpot game B is obtained even if the second jackpot symbol is “4”. Furthermore, if the first jackpot symbol is “7”, the jackpot game B is the jackpot game B regardless of the type of jackpot symbol in the second to third jackpots. That is, if the jackpot symbol is “7”, the jackpot game B has priority in the future jackpot game (fourth time) from the next jackpot game (second time) regardless of the type of the winning symbol. And executed.

  Further, in this example, when the jackpot symbol is “1” or “5”, the gaming state becomes the probability variation mode until the next jackpot, and the jackpot lottery is performed with high probability. When the jackpot symbol is “3”, 60 rotations after the jackpot is completed, and when the jackpot symbol is “7”, the 30 rotations after the jackpot is in the probability variation mode. On the other hand, when the jackpot symbol is “2”, “4”, “6”, and “8”, the mode is not shifted to the probability variation mode. In addition, after the jackpot is over, 100 rotations are in the time reduction mode. The time-saving mode refers to a gaming state in which the time for which the special symbol fluctuates is shorter than that in the normal game.

  FIG. 4 shows an electrical configuration of the pachinko machine 1 according to the present embodiment. The pachinko machine 1 includes a main board 30A, a sub board 30B, a display control board 30C, a prize ball payout control board 30D, and an external relay board 30D. The main board 30A functions as a control center that controls the entire pachinko machine 1. The main board 30A includes a CPU 31, a clock generation circuit 32, a RAM 34, a ROM 35, a transmission timing control circuit 36, a data transmission circuit 37, an input port 38, and an output port 39.

  The CPU 31 is connected to each component of the main board 30A excluding the transmission timing control circuit 36 via a bus (not shown). The CPU 31 controls each component by executing the control program CP. The control program CP describes how to operate the entire pachinko machine 1. The clock generation circuit 32 includes an oscillation circuit including a crystal resonator, generates a fixed-cycle reference clock signal CLK, and supplies it to the CPU 31.

  In addition, the control program CP executes a lottery. In this lottery, for example, a counter that increments the count value every time an interrupt process is executed and cycles through the count values from 0 to 630 is used. Then, the count value at the timing when the game ball 2 passes through the start winning opening is acquired as a lottery value, and the lottery value is executed by determining whether or not a predetermined hit value matches. If the number of hit values is increased, the hit probability can be changed. In this example, in the normal mode, the hit value is 2 so that the probability of jackpot is 1 / 315.5, and in the probability variation mode, the hit value is 1 / 63.1 by setting the hit value to 10. It is set. As described above, a prime number such as 631 is often used as the width of the circulating counter serving as a denominator of probability. Next, the RAM 34 functions as a work area of the CPU 31 and stores intermediate results of arithmetic processing, data generated as necessary, flags used for various controls, and the like.

  Next, various sensors 41 to 49 are connected to the input port 38. The left and right gate sensors 41 and 42 are provided on the left and right gates 12 and 13, and detect that the game ball 2 has passed through the left and right gates 12 and 13, and output detection signals 41a and 42a. To do. Upper left / upper right / lower left / lower right winning opening sensors 43 to 46 are provided at upper left / upper right / lower left / lower right winning openings 14 to 17 and detect that the game ball 2 has passed through these winning openings. Detection signals 43a to 46a. The start winning port sensor 47 is provided at the start winning port of the electric tulip 11, detects that the game ball 2 has passed through the start winning port, and outputs a detection signal 47a. The big prize opening sensor 48 is provided in the big prize opening in the big attacker 20, detects that the game ball 2 has passed through the big prize opening, and outputs a detection signal 48a. The specific area sensor 49 is provided in a specific area (V zone) of the special winning opening, detects that the game ball 2 has passed the specific area, and outputs a detection signal 49a.

  Next, an electric tulip opening solenoid 51, a special prize opening opening solenoid 52, and a specific area opening solenoid 53 are connected to the output port 39. When the drive signal 51a is supplied, the electric tulip opening solenoid 51 moves the pair of blades so that the electric tulip 11 opens. When the driving signal 52a is supplied, the large winning opening solenoid 52 drives a seesaw mechanism provided in the large attacker 20 to open the large winning opening. When the drive signal 53a is supplied, the specific area release solenoid 53 drives a seesaw mechanism provided in the special winning opening so that the game ball 2 can easily enter the V zone.

  Next, the sub board 30B, the display control board 30C, and the prize ball payout control board 30D each include a CPU, a RAM, and a ROM, and the CPUs of the sub board 30B and the prize ball payout control board 30D are the main board 30A. The CPU 31 receives a command transmitted from the CPU 31 and executes predetermined processing. For example, when a command specifying an effect pattern of an image to be displayed on the display device 60 is transmitted from the CPU 31 of the main board 30A, the CPU of the sub board 30B receives this command. Then, the CPU transmits the image data read from the ROM to the display control board 30C. The CPU of the display control board 30C writes the received image data to the VRAM, and outputs the image data stored in the VRAM to the display device 60 at a predetermined timing. As a result, the screen shown in FIG. 2 is displayed on the display device 60. Further, a speaker 61 is connected to the display control board 30C, and the CPU of the display control board 30C reads sound data stored in the ROM at a predetermined timing. The read sound data is supplied to the speaker 61 via the DA converter. Thereby, the reach effect and the sound effect at the time of the big hit can be emitted from the speaker 61.

  The prize ball payout control board 30D has a prize ball counting sensor 62 for counting the prize balls to be paid out from the pachinko machine 1, a prize ball delivery motor 63 for discharging the prize balls, and an out ball detection sensor for detecting the out balls. 64, an out ball discharge solenoid 65 for discharging the out ball is connected. The prize ball payout control board 30D receives the prize ball command from the CPU 31 and controls each unit so as to pay out the necessary prize balls.

  The external signal relay board 30E is connected to a computer or the like that manages the pachinko machine 1 throughout the hall, and outputs various signals indicating the number of rotations of special symbols, the number of jackpot games, errors, and the like.

  Next, the operation of the pachinko machine 1 will be described. When the power is turned on, the CPU 31 first executes initialization processing, and then executes interrupt processing at predetermined time intervals. 5 to 10 are flowcharts showing the processing contents of the interrupt processing.

  First, the CPU 31 determines whether or not there is a ball in the start winning opening based on the detection signal 47a (step S10). If there is a winning ball in the starting winning opening, a command for instructing a winning ball payout process is transmitted to the sub-board 30B (step S11), and it is determined whether or not the number of special symbol operation memory is less than four (step S12). ). The special symbol operation memory number is stored in a predetermined storage area of the RAM 34.

  Next, the CPU 31 acquires a special symbol jackpot lottery value L1 and a special symbol lottery value L2 and stores them in the RAM 34 (step S13). Thereafter, the CPU 31 increments the special symbol operation memory number by “1” (step S14), and transmits the special symbol operation memory number to the sub-board 30B (step S15). In this case, in the sub-board 30B, the process is executed so as to increase the number of lighting of the holding ball area 60C by one.

  When the determination condition of step S10 or step S12 is not satisfied, and when the process of step S15 is completed, the CPU 31 determines whether or not the special symbol operating memory number is greater than 0 (step S16). When there is a holding ball, the special symbol working memory number is 1 or more, and the determination condition of step S16 is satisfied. In this case, the CPU 31 determines whether or not the special symbol is operating, the special electric character is operating, or the big hit game with reference to the special symbol active flag, the special electric character operating flag, or the big hit game flag ( Step S17). The special symbol being operated means that the special symbol is variably displayed, and the special electric character being activated means that the process for opening and closing the large attacker 20 is being executed. However, the number of times the large attacker 20 is opened and closed is not limited to one. For example, when performing three times of opening and closing, the time until the opening and closing of the three times is completed corresponds to the special electric power operation. That is, it is a period from the start of opening of the large attacker 20 until a predetermined end condition is satisfied and the large attacker 20 is closed, and is a period in which one special electric role is activated. The special symbol operating flag indicates that the special symbol is operating, the special electric power operating flag indicates that the special electric power is operating, and the jackpot gaming flag indicates that the jackpot game is being played. The special electric combination is a special electric combination.

  When the determination condition in step S17 is negative, the CPU 31 subtracts “1” from the special symbol operation memory number, updates the stored contents of the RAM 34 (step S18), and transmits the special symbol operation memory number to the sub-board 30B. (Step S19). As a result, the number of reserved balls is reduced by “1”. Next, the CPU 31 executes a rotation speed digest process (step S20).

  FIG. 13 shows the contents of the rotational speed digestion process. First, the CPU 31 determines whether or not the mode is the probability variation mode with reference to the probability variation mode flag (step S140). If the gaming state is the probability variation mode, the CPU 31 determines whether or not the probability variation speed is “−1” (step S141). As will be described later, when the probability variation mode is maintained from the end of a jackpot game until the next jackpot game is started, the probability variation speed is set to “−1” (see step S122 in FIG. 12). ). In such a case, there is no need to manage the probability variable rotation speed, so step S142 to step S144 are omitted, and the process proceeds to step S145.

  On the other hand, if the probability variable rotational speed is not “−1”, the CPU 31 executes a probability variable rotational speed subtraction process for decrementing the probability variable rotational speed by “1” (step S142), and determines whether the probability variable rotational speed is “0”. (Step S143). If the probability variation speed is “0”, the probability variation mode flag is cleared (step S144). If the probability variation speed is not “0”, the process proceeds to step S145 without clearing the flag.

  In step S145, the CPU 31 determines whether or not the gaming state is the time reduction mode with reference to the time reduction mode flag. If the gaming state is the time reduction mode, the CPU 31 executes a probability variable rotation number subtraction process for decrementing the time reduction speed by “1” (step S146), and further determines whether or not the time reduction speed is “0” (step S146). S147). If the time reduction speed is “0”, the time reduction mode flag is cleared (step S144). If the time reduction speed is not “0”, the processing is terminated without clearing the pufferfish. In addition, since it is not necessary to manage a speed reduction speed when it does not correspond to a time reduction mode, a process is complete | finished also when the determination conditions of step S145 are denied.

  Thereafter, the CPU 31 determines whether or not the mode is the probability variation mode with reference to the probability variation mode flag (step S21). In the case of the probability variation mode, the CPU 31 executes a special symbol jackpot lottery with a high probability (step S22). The jackpot winning probability is, for example, 1 / 63.1. Specifically, it is determined whether or not the ten winning values determined in advance and the jackpot lottery value L1 match. If they match, the jackpot is determined, and if they do not match, the game is lost. On the other hand, if it is not the probability variation mode, the CPU 31 advances the processing to step S23, and executes a special symbol jackpot lottery with a normal probability (low probability). The jackpot winning probability is, for example, 1 / 315.5. Specifically, it is determined whether or not two predetermined hit values and the jackpot lottery value L1 match. If they match, the jackpot is determined, and if they do not match, the game is lost.

  Next, the CPU 31 determines a stop symbol (step S24). In this process, when the jackpot is won, the jackpot symbol is determined based on the symbol lottery value L2. Specifically, the lottery division width of “2”, “4”, “6”, and “8” is X1, the lottery division width of “1” and “5” is X2, and the lottery division of “3” Is set so that X1> X2> X3> X4, and it is determined which lottery category the symbol lottery value L2 belongs to. As shown in FIG. 3 (A), the width of the lottery classification is set in this way. The game value given to the player is different depending on the winning symbol, and the probability that the larger game value is given is set to a lower probability. This is because the wave of the ball can be made smaller. In particular, in the present embodiment, when the jackpot is “7” or “3”, the jackpot game B is preferentially selected regardless of the type of jackpot symbol in the next jackpot. Therefore, in the case of a big hit with these symbols, a large amount of game balls 2 will be paid out, so by lowering the probability, it is possible to keep the player expecting while suppressing the wave of outgoing balls It becomes.

  Next, the CPU 31 determines the symbol variation time with reference to the time reduction mode flag (step S26). The short time mode flag is set at the start of the short time mode and cleared at the end. The CPU 31 sets the symbol variation time to, for example, 10 seconds when the time reduction mode flag is set, and sets it to, for example, 2 seconds when the flag is cleared. Thereafter, the CPU 31 starts a timer for measuring the special symbol variation time (step S27), transmits a command for instructing the special symbol variation start to the sub-board 30B (step S28), and further, the special symbol operating flag. Is set (step S29). The above is the process related to the start of special symbol fluctuation.

  Next, the CPU 31 executes processing related to the start of normal symbol fluctuation. First, in step S6 shown in FIG. 6, the CPU 31 determines whether or not the game ball 2 has passed the left / right gate 12 or 13 based on the detection signals 41a and 42a. When the game ball 2 has passed the left / right gate 12 or 13, it is determined whether or not the normal symbol operation memory number is less than 4 (step S31). The normal symbol operation memory number is stored in a predetermined storage area of the RAM 34.

  Next, the CPU 31 acquires the winning lottery value L3 for the normal symbol and stores it in the RAM 34 (step S32). Thereafter, the CPU 31 increments the normal symbol operating memory number by “1” (step S33), and transmits the normal symbol operating memory number to the sub-board 30B (step S34). In this case, in the sub-board 30B, the process is executed so as to increase the number of lighting of the holding ball area 60D by one.

  When the determination condition of step S30 or step S31 is not satisfied, and when the process of step S34 is completed, the CPU 31 determines whether or not the normal symbol operating memory number is greater than 0 (step S35). If there is a holding ball, the normal symbol working memory number is 1 or more, and the determination condition of step S35 is satisfied. In this case, the CPU 31 determines whether or not the normal symbol operation or the normal electric service operation is performed with reference to the normal symbol operation flag or the normal electric service operation flag (step S17). “Normal symbol in operation” means that the normal symbol is variably displayed, and “in normal electric charge operation” means that the process of opening and closing the electric tulip 11 is being executed. However, the number of times the electric tulip 11 is opened and closed is not limited to one. For example, when performing three times of opening and closing, the period until the opening and closing of the three times is completed corresponds to the normal electric service operation. That is, it is a period from when the electric tulip 11 starts to expand until a predetermined end condition is satisfied and the electric tulip 11 expands and contracts, and is a period during which one ordinary electric role is activated. The normal symbol operating flag indicates that the normal symbol is operating, and the normal electric utility operating flag indicates that the normal electric utility is operating. The ordinary electric combination is an ordinary electric combination.

  If the determination condition in step S36 is negative, the CPU 31 subtracts “1” from the normal symbol operating memory number, updates the stored contents of the RAM 34 (step S37), and transmits the normal symbol operating memory number to the sub-board 30B. (Step S38). As a result, the number of reserved balls is reduced by “1”.

  Thereafter, the CPU 31 determines whether or not the mode is the probability variation mode with reference to the probability variation mode flag (step S39). When it is in the probability variation mode, the CPU 31 executes a big hit lottery for normal symbols with a high probability (step S40). On the other hand, when not in the probability variation mode, the CPU 31 executes a normal symbol jackpot lottery with a normal probability (low probability) (step S41). Thereafter, the CPU 31 determines a stop symbol (step S42). In this process, if the jackpot is won in the process of step S40 or S41, the normal symbol is determined to be “◯”, and if lost, the normal symbol is determined to be “x”.

  Next, the CPU 31 determines whether or not it is the time reduction mode with reference to the time reduction mode flag (step S43), and if it is the time reduction mode, the normal symbol variation time is set to 5.1 seconds (step S44). . On the other hand, if the mode is not the time reduction mode, the normal symbol variation time is set to 28.5 seconds (step S45). Thereafter, the CPU 31 starts a timer for measuring the normal symbol variation time (step S46), transmits a command for instructing normal symbol variation start to the sub-board 30B (step S47), and further, the normal symbol operating flag. Is set (step S48).

  Next, the CPU 31 determines whether or not the special symbol is operating with reference to the special symbol operating flag (step S49). If the special symbol is in operation, it is further determined whether or not the time during measurement has reached the special symbol variation time (step S50). If the determination condition is satisfied, a command for confirming the special symbol is sent to the sub-board 30B. (Step S51). Thereby, the symbol determined in step S24 is stopped. Thereafter, the CPU 31 clears the special symbol operating flag (step S52), and determines whether or not it is a big hit (step S53). If it is a big hit, a big hit game start process is executed (step S54).

  FIG. 11 shows the contents of the jackpot start process. First, the CPU 31 clears the time reduction mode / probability change mode flag (step S100), clears the round continuation flag (step S101), and further sets a jackpot gaming flag (step S102). The round continuation flag is set when a condition for continuing the round is satisfied. In this example, it is a condition that the game ball 2 has passed through the V zone in step S92 described later. It is not necessary to provide conditions for continuing the round. The jackpot game flag is a flag indicating that a jackpot game is being played.

  Next, the CPU 31 determines whether or not the jackpot symbol is “3” (step S103). When the determination condition is satisfied, the CPU 31 further determines whether or not a high-round game is being performed (step S104). The high round game means a state in which the jackpot game B is confirmed at the next jackpot. Whether or not a high land game is in progress is determined by whether or not a high round game flag is set. If the determination condition in step S104 is affirmed, the CPU 31 adds “2” to the number of high rounds (step S105). On the other hand, when the determination condition of step S104 is negative, it is the first win of the high round game. In this case, “2” is set as the number of high lands (step S106), and a high round game flag is set (step S107).

  Next, the CPU 31 determines whether or not the jackpot symbol is “7” (step S108). When the determination condition is satisfied, the CPU 31 further determines whether or not a high-round game is being performed (step S109). If the game is in the high land game, the CPU 31 adds “4” to the number of high rounds (step S110). If the game is not in the high land game, the CPU 31 sets “4” as the high land number (step S111). A flag is set (step S112). Thereafter, the CPU 31 sets a special power combination operating flag (step S113) and ends the jackpot game start process.

  Thus, in the jackpot game start process, the CPU 31 sets the high round game in-progress flag and sets the high number of rounds when the first jackpot symbol is “3” or “7”. Further, in the jackpot game end process described later, when the jackpot game is ended, the number of high rounds is decremented by “1”, and when this becomes “0”, a process of clearing the high round game flag is executed. Further, the CPU 31 refers to the high-round game flag and executes the jackpot game B during the high-round game regardless of the type of the jackpot symbol. That is, two types of independent processes are associated with each other via the high-round gaming flag. The first process manages the high round game flag, and the second process selectively executes the jackpot game A and the jackpot game B according to the high round game flag. The CPU 31 that executes the second process functions as a game management means that selectively executes the jackpot game A (first jackpot game) and the jackpot game B (second jackpot game). The CPU 31 that executes the first process When the jackpot symbol is “3” or “7” (when the winning mode is the second mode), the jackpot game B is executed by the game management means, and a future number of times from the next jackpot game is determined in the future. As a game control means for causing the game management means to execute the jackpot game B instead of the jackpot game A even if the jackpot symbol is other than “3” or “7” in the jackpot game (even if the winning mode is the first mode). Function.

  Returning to FIG. When the jackpot game start process ends, the CPU 31 executes an attacker release process (step S55). FIG. 14 shows the contents of the attacker release process. First, the CPU 31 clears the winning ball count (step S150). The winning ball count indicates the number of winning balls in one round. Next, the CPU 31 sets the attacker opening time to, for example, 30 seconds (step S152), and sets the maximum number of winning balls to, for example, 10 (step S152). Then, the CPU 31 starts a timer for measuring the attacker release time (step S153), and thereafter releases the large attacker (step S154).

  Returning to FIG. When the determination condition in step S49, step S50, or step S53 is negative, or when the attacker release process ends, the CPU 31 refers to the normal symbol operating flag to determine whether or not the normal symbol is operating. Determination is made (step S56). If the normal symbol is operating, it is further determined whether or not the time during measurement has reached the normal symbol variation time (step S58), and if the determination condition is satisfied, a command for determining the normal symbol is sent to the sub-board 30B. (Step S59). Thereby, the symbol determined in step S42 is stopped. Thereafter, the CPU 31 clears the normal symbol operating flag (step S59) and determines whether or not it is a hit (step S60). If it is a win, the normal power combination operating flag is set (step S61), and the electric tulip opening process is executed (step S62).

  FIG. 15 shows the processing contents of the electric tulip opening process. First, the CPU 31 determines whether or not the mode is the time reduction mode with reference to the time reduction mode flag (step S155). If the time reduction mode flag is set, the setting is made such that 1.6 seconds is repeated three times when the electric tulip 11 is opened (step S156), and if the time reduction mode flag is cleared, the electric tulip 11 is released 0. It is set to perform once in 6 seconds (step S157). Next, the CPU 31 starts a timer for measuring the opening time of the electric tulip 11 (step S158), and opens the electric tulip 11 (step S159).

  Returning to FIG. If the determination condition in step S56, step S57, or step S60 is negative, or if the electric tulip opening process is terminated, the CPU 31 advances the process to step S63 shown in FIG. In step S63, the CPU 31 determines whether or not the special power combination is operating with reference to the special power combination operating flag. When the special power combination operating flag is set, the CPU 31 determines whether or not the attacker release time set for the measurement time has been reached (step S64). If the determination condition is affirmed, the CPU 31 closes the large attacker (step S65) and clears the special electric utility operating flag (step S66). Next, the CPU 31 determines whether or not the round continuation flag is set (step S67). If the round continuation flag is cleared, the big hit game ending process is executed (step S68). When the jackpot game end process is performed in this determination process, it is a case where the large attacker is not able to enter the V zone in the big winning opening while the special attacker is open and does not digest the prescribed number of rounds. The jackpot game ends.

  FIG. 12 shows the contents of the jackpot game end process. First, the CPU 31 clears the jackpot game flag (step S120). Next, the time reduction mode flag is set, and the time reduction speed is set to 100 (step S121). Next, the CPU 31 determines whether or not the jackpot symbol is “1” or “5” (step S122). If the determination condition is affirmed, the probability variation mode flag is set (step S123), and the probability variation speed is set to "-1" (step S124). The actual probability rotation speed does not take “−1”, and this setting means that the probability variation mode is maintained until the next big hit.

  On the other hand, when the determination condition of step S122 is negative or when the process of step S124 ends, the CPU 31 determines whether or not the jackpot symbol is “3” (step S125). If the determination condition is affirmative, the probability variation mode flag is set (step S126), and the probability variation speed is set to “60” (step S127). Furthermore, when the determination condition in step S125 is negative or when the process in step S127 ends, the CPU 31 determines whether or not the jackpot symbol is “7” (step S128). If the determination condition is affirmative, the probability variation mode flag is set (step S129), and the probability variation speed is set to “30” (step S130).

  Next, when the determination condition of step S128 is negative or when the process of step S130 is completed, the CPU 31 determines whether or not a high round game is in progress with reference to the high round game flag (step S131). If the high round game is being played, the high round number is subtracted (step S132), and it is determined whether or not the high round number is "0" (step S133). If the number of high rounds is “0”, the high round gaming flag is cleared (step S134). Then, when the determination condition of step S131 or step S133 is negative or when step S134 is completed, the jackpot game ending process is ended.

  As described above, since the jackpot game is determined according to the type of jackpot symbol (winning mode) at the end of the jackpot game, the process of giving priority to the jackpot game B over the jackpot game A, It can be managed independently. For example, as shown in FIG. 3 (B), when the jackpot is won with “7” in the first round, the jackpot game from the second round to the fourth round is a 16-round jackpot regardless of the jackpot symbol. Although it becomes the game B, the jackpot symbol from the second time to the fourth time is not a probable variation symbol as shown in FIG. Accordingly, the probability changing mode is not shifted from the second time to the fourth time. In this way, since different types of game elements such as the number of rounds and probability variation are managed independently, it is possible to give diversity to the game.

  Returning to FIG. When the determination condition of step S63 or step S64 is denied, when the determination condition of step S67 is affirmed, or when the jackpot game end process is ended, the CPU 31 advances the process to step S69. In step S <b> 69, the CPU 31 determines whether or not the normal power combination operation is being performed with reference to the normal power combination operation flag. If the normal electronic combination is being operated, the CPU 31 determines whether or not the measurement time has reached the opening time of the electric tulip 11 (step S70). If it has reached, the CPU 32 closes the electric tulip 11 (step S71), and clears the normal electric utility operating flag (step S72).

  When the determination condition of step S69 or step S70 is negative or when the process of step S72 is completed, the CPU 31 advances the process to step S73 shown in FIG. 9 and refers to the ongoing round flag as to whether the round is ongoing. Judgment. If the round is continuing, the CPU 31 determines whether or not the special power combination is operating (step S74). When this determination condition is denied, it is an interval period between a round and a next round in a jackpot game, or the end of the last round. If the determination condition in step S74 is negative, the CPU 31 determines whether or not a high-round game is being performed (step S75).

  The CPU 31 sets the round number upper limit determination value to 16 if it is during a high round game (step S76), and sets the round number upper limit determination value to 10 if it is not during a high round game (step S77). The round number upper limit determination value is the maximum number of rounds allowed in one jackpot game. Next, the CPU 31 determines whether or not the round has been digested to the upper limit of the number of rounds (step S78). Specifically, it is determined whether or not the count value of the round number counter matches the round number upper limit determination value. If the two match, the determination condition in step S78 is affirmed, the CPU 31 clears the round continuation flag (step S79), and executes a jackpot game end process (step S80). The jackpot game ending process has already been described with reference to FIG.

  On the other hand, if the determination condition in step S78 is negative, the CPU 31 advances the process to step S81 and increments the count value of the round number counter by “1”. Next, the CPU 31 sets a special electric utility operating flag (step S82), and executes an attacker release process (step S83). Since the attacker releasing process has already been described with reference to FIG. 14, the description thereof is omitted here.

  Thereafter, the CPU 31 advances the processing to step S84 shown in FIG. 10 to determine whether or not the player has entered the winning opening with reference to the detection signals 43a to 47a. If there is a winning ball at the winning opening, a command for executing a winning ball payout process is transmitted (step S84). The payout of prize balls is processed by the prize ball payout control board 30B.

  When the process of step S84 ends or the determination condition of step S84 is denied, the CPU 31 determines whether or not there is a ball in the big winning opening with reference to the detection signal 48a (step S86). If there is a winning ball at the big winning opening, the process proceeds to step S87, and a command for executing a winning ball payout process is transmitted (step S87). Thereafter, the CPU 31 increments the count value of the winning ball counter by “1” (step S88), and determines whether the count value of the winning ball counter has reached the maximum winning ball value (step S89). In this example, the winning ball maximum value is set to 10. If the determination condition in step S88 is affirmed, the CPU 31 closes the attacker (step S90), clears the special electric utility operating flag (step S91), and advances the process to step S92. Note that the process proceeds to step S92 also when the determination condition of step S86 or step S89 is negative.

  In step S92, the CPU 31 determines whether or not the game ball 2 has passed through the V zone with reference to the detection signal 49a. If it passes through the V zone, the CPU 31 sets a round continuation flag (step S93). If it does not pass through the V zone, the CPU 31 ends the process without setting the round continuation flag. As described above, the fact that the round continuation flag is set is a precondition for the attacker release process (see step S73 and step S83 in FIG. 9), so that the game ball 2 passes through the V zone to continue the round. It becomes a condition.

  Although the present invention has been described with reference to the most practical and preferred embodiments at the present time, the invention is limited to the embodiments disclosed herein. However, the present invention can be changed as appropriate without departing from the scope or spirit of the invention that can be read from the claims and the entire specification, and a gaming machine and a control method therefor are also included in the technical scope of the present invention. Must be understood as being. For example, the following modifications are naturally included in the present invention.

(1) In the above-described embodiment, the 10-round jackpot game A and the 16-round jackpot game B are adopted. However, the type of jackpot game of the present invention is not limited to the difference in the number of rounds. It is sufficient if the number of game balls 2 to be paid out in one big hit game is light. That is, it is only necessary that there is a difference in the game value that can be given to the player. For example, a common number of rounds may be used to provide a difference in the number of winning balls that can be won in one round, with the smaller number being the jackpot game A and the larger number being the jackpot game B. Or you may provide a difference in game value by giving a difference in the continuation conditions of a round. For example, the jackpot game A has the game value of the jackpot game B higher than the game value of the jackpot game A by continuing the round unconditionally on the condition that the game ball 2 enters the V zone. May be.

(2) In the above-described embodiment or modification, whether or not to shift to the high round game is determined according to the type of jackpot symbol, but the present invention is not limited to this, and the display device 60 Whether or not to shift to the high round game may be determined according to the display mode. For example, the case where four identical symbols are arranged in five specific display areas 60A is replaced with the case where the symbol “3” is a jackpot symbol in the above-described embodiment, and the case where five identical symbols are arranged is described above. In the above embodiment, the symbol “7” may be replaced with the jackpot symbol. Further, in consideration of the type of symbol, the case where four symbols “7” are arranged in five specific display areas 60A is replaced with the case where symbol “3” is a jackpot symbol in the above-described embodiment. The case where the symbol “7” is arranged may be replaced with the case where the symbol “7” is a jackpot symbol in the above-described embodiment. In other words, the elements specifying the winning mode include the type of symbol, the number of the same symbol, or a combination thereof.

(3) In the above-described embodiment or modification, the jackpot game B includes a game in which 16 rounds are confirmed twice and a game round of 16 is confirmed four times, and the jackpot game B includes a plurality of game states. The CPU 31 selected and executed the gaming state according to the jackpot symbol. In the present invention, the difference between the jackpot game A and the jackpot game B is the value of the game value that can be granted. Therefore, even if the jackpot game B includes a plurality of game states with different numbers of rounds, the smallest round of them The number should be larger than the number of rounds of jackpot game A. For example, as shown in FIG. 16, when the jackpot symbol is “2”, “4”, “6”, or “8”, the 10-round jackpot game A and the jackpot symbol is “1” or “5”. In this case, 13 rounds of jackpot game B may be used, and when the jackpot symbol is “3” or “7”, 16 rounds of jackpot game B may be used. Further, the jackpot game B includes a plurality of game states in which at least one of the number of rounds or the number of times that the jackpot game B is prioritized over the jackpot game A is different, and the CPU 31 selects one game from the plurality of game states. A state may be selected and executed.

  In this case, the CPU 31 may select and execute one gaming state from a plurality of gaming states according to the type of jackpot symbol, that is, the winning mode. More specifically, the gaming state of jackpot game B is managed by dividing it into symbol types, and the jackpot symbol type related to the start of jackpot game B is associated with a plurality of gaming states and stored in ROM 35. The CPU 31 identifies the type of jackpot symbol determined by the lottery, and refers to the stored contents of the ROM 35 to manage the gaming state of the jackpot game B so that the gaming state corresponds to the identified type of jackpot symbol. That's fine.

  Further, the CPU 31 may select and execute one gaming state from among a plurality of gaming states by lottery. More specifically, the gaming state of jackpot game B is managed by dividing it into symbol types, and the jackpot symbol type related to the start of jackpot game B and a plurality of gaming states are stored in the ROM 35 in association with each other. The CPU 31 specifies the type of jackpot symbol determined by lottery. Further, the CPU 31 specifies the type of jackpot symbol determined by the lottery, refers to the stored contents of the ROM 35, and sets the gaming state of the jackpot game B so as to be in a gaming state corresponding to the specified type of jackpot symbol. Just manage.

  In addition, the CPU 31 may select and execute one gaming state from among a plurality of gaming states according to the pitch rate. In this case, the exit rate and a plurality of game states are associated with each other and stored in the ROM 35, and the CPU 31 calculates the exit rate based on the number of payout balls and the number of out balls, accesses the ROM 35, and What is necessary is just to manage a gaming state so that it may become a gaming state corresponding to the calculated payout rate.

(4) In the above-described embodiment or modification, the time-saving mode is uniformly set to 100 rotations, but the present invention is not limited to this, and the number of times of the time-saving mode corresponding to the winning mode is determined in advance.
