Description

  The present invention relates to a bullet ball gaming machine that plays a game by firing a game ball on a game board surface.

  A ball game in which a game ball is fired on a game board surface provided with a plurality of entrances, and when a game ball enters one of the entrances, a predetermined number of game balls are paid out as prize balls The machine is known. In addition, the game board surface is provided with a special entrance called a start opening, and a special symbol display device that displays a special symbol (sometimes abbreviated as a special figure). When a game ball enters, a special symbol change display is started, and when a stop symbol is displayed with a winning symbol, a special variable entrance called a big prize opening is opened to perform a big hit game. Machines (so-called pachinko machines) are also widely known. Since the big prize opening is normally closed so that the game ball cannot enter, but in the open state it will enter with high probability, so if it is a big hit game, the player will receive many prize balls It becomes possible to acquire.

  In most cases, the starting port is also variable, and can be switched between a normal state and an open state where game balls can easily enter. It is necessary to satisfy the following conditions. That is, the game board surface is provided with a normal symbol display device for displaying a normal symbol in a variable manner, and it is necessary to display the normal symbol in a variable manner and stop the normal symbol. Here, the normal symbol is a symbol different from the special symbol described above, and the normal symbol display device is a display device different from the special symbol display device described above. The game board surface is provided with a pass gate through which a game ball can pass, and when the game ball is passed through the pass gate, the normal symbol variation display is started. When the normal symbol is hit and displayed as a stop symbol, the start port is opened for a certain period of time. Thus, when the starting port is opened, it becomes easy to enter the game ball, and accordingly, it is possible to easily generate the big hit game.

  In addition, after the big hit game is over, a game state (so-called time-short state) is started in which the variation time of the special symbol and the normal symbol is shortened. During this short state, not only the variation time of the special symbol and the normal symbol is shortened, but also the opening time of the starting port is prolonged, so that it can be said that the gaming state is advantageous to the player. Thus, by providing a short time state after the big hit game, it is possible to attract the player's interest to the game even after the big hit game ends (Patent Document 1). In addition, a technique that aims to further attract the interest of the player by changing the opening mode of the start port has been proposed (Patent Document 2).

  However, in the conventional technique, even if the big hit game is finished, the start opening is not easily opened, and as a result, the player may be frustrated. It is due to the following player psychology that the start opening is not opened after the end of the big hit game. First, as described above, after the big hit game, since the opening time of the start port is extended, it becomes easy to allow the game ball to enter the start port. Also, after the big hit game, the special symbol variation time is shortened, so even if the game ball enters the start opening and the special symbol variation display is started, it will be stopped immediately, and the special symbol variation display frequency will be displayed. Can be increased. For this reason, when the big hit game is completed, the player wants to start the big hit game as soon as possible by putting as many game balls as possible at the starting port. However, if the start port is not easily opened after the big hit game, the game ball cannot enter the start port, and the player becomes annoyed.

  In addition, it is common for the start opening to open relatively soon after the end of the big hit game, and it is rare that it will not open. For this reason, if such a thing happens unfortunately, it may result in water being poured into the game interest of the player who has been excited by the big hit game, and the player may stop the game. The situation in which the player stops the game when the big hit game is finished is a loss from the business of the game hall, which is also a big problem from this point of view.

  The present invention has been made to solve the above-described problems of conventional ball game machines, and can reliably avoid a situation where the start port is not easily opened after the end of the big hit game. The purpose is to provide a machine.

In order to solve at least a part of the above-described problems, the bullet ball game machine of the present invention employs the following configuration. That is,
A game provided with a normal symbol display device capable of displaying normal symbols, a special symbol display device capable of displaying special symbols, and a special prize opening which is normally closed and can be changed to an open state. In a ball game machine that fires game balls on the board and plays games,
A variable start opening configured to be switched between a normal state and an open state in which a game ball can be entered more easily than the normal state, and when the game ball enters the start of the change display of the special symbol,
When a game ball enters the variable start port, a determination random number acquisition unit that acquires a determination random number for determining whether or not the game is successful;
When the special symbol starts to change display, the determination unit for determining whether or not the determination based on the determination random number;
When the special symbol is not variably displayed at the time of entering the variable start opening, the special symbol is started to be variably displayed. A special symbol variation control means for performing a control to stop and display the special symbol at a predetermined off symbol when the result of the determination on whether or not the result is wrong is displayed.
If the special symbol is variably displayed at the time of entering the variable start opening, the success / failure determination random number obtained at the time of entering the ball is suspended to start a new variable display after the special symbol is stopped. Holding storage means for storing as,
When the hold occurs, prior to the determination of the success / failure by the success / failure determination unit, a hold / failure determination unit that determines whether or not the hold is based on the determination result random number stored as the hold;
When the special symbol is stopped and displayed at the winning symbol, a big hit game executing means for executing a big hit game with the big winning opening being opened;
When the predetermined condition is established during the game, the normal symbol variation display is started, and when the normal symbol is stopped and displayed with the predetermined hit symbol, the variable start port is opened for a predetermined time. When,
When the holding success / failure determining means determines that the holding success / failure is a win, it includes a normal figure fluctuation shortening means for shortening the fluctuation time of the normal symbol until the big hit game is finished. And

  In such a ball game machine of the present invention, when the predetermined condition is established during the game, the normal symbol variation display is started, and after the predetermined variation time, when the normal symbol is stopped and displayed in the symbol, the variable start port Becomes an open state. Further, when a game ball enters the variable start port, the special symbol variation display is started, and when the special symbol is stopped and displayed in the winning symbol, the big hit game is started. Here, whether or not the special symbol is stopped and displayed as a winning symbol is determined at the time of starting the variation of the special symbol based on the randomness determination random number acquired when the game ball enters the variable start port. However, in the ball game machine according to the present invention, even when the randomness determination random number is acquired (that is, the holding stage), whether or not the winning is determined in advance (that is, the winning hold is determined) If it occurs), the normal symbol variation time is shortened until the big hit game ends.

  In this way, even if the display of fluctuation of the normal symbol is started near the end of the big hit game, the fluctuation time of the normal symbol becomes a shortened state triggered by the occurrence of the hit holding that caused the occurrence of the big hit game. Therefore, the normal symbol can be stopped and displayed immediately. For this reason, since the normal symbols are not easily stopped and displayed after the big hit game is over, it is possible to avoid a situation in which the variable start port is not opened and the player is frustrated.

  In addition, when a winning hit occurs, the normal symbol variation time is shortened before the big hit game is started. Therefore, it is possible to cause the player to detect the occurrence of the big hit game by changing the fluctuation time of the normal symbol, and it is possible to further stimulate the player's interest in the game.

  Further, the above-described bullet ball game machine of the present invention may have the following configuration. First, it is a fixed type starting port (fixed starting port) through which a game ball can always enter and can be switched between a normal state and an open state, but a variable start port through which a game ball cannot enter if it is not open. And set up. As for the special symbol display device, a first special symbol display device and a second special symbol display device are provided, and the first special symbol display device is used for entering a game ball into the fixed start port. The first special symbol is displayed in a variable manner, and the second special symbol is displayed in a variable manner in the second special symbol display device when the ball enters the variable start port. Furthermore, when starting to display the variation of the first special symbol or the second special symbol, in addition to determining whether or not it is true, if the determination result is positive, the type of winning is also determined. When the second special symbol is variably displayed, the winning type is determined under conditions that are more advantageous to the player than when the first special symbol is variably displayed. If either the first special symbol or the second special symbol can be displayed in a variable manner, the second special symbol may be given priority for the variable display.

  In the ball game machine having such a configuration, as long as the game ball is inserted into the variable start port, the second special symbol is displayed in a variable manner, and the type of winning is determined under conditions that are advantageous to the player. . However, since the variable starting port cannot enter the game ball unless it is in the open state, the variable starting port must be opened in order for the player to advance the game under advantageous conditions. Therefore, in such a ball game machine, if the second start opening does not readily open after the big hit game, the game cannot be continued under advantageous conditions, and the player may be annoyed. In this regard, in the ball and ball game machine of the present invention, when the hit is held, the fluctuation time of the normal symbol is shortened until the end of the big hit game, so even if the normal symbol change display is near the end of the big hit game. Even when is started, the normal symbol stops immediately. For this reason, after the big hit game is finished, the variable start port is quickly opened to allow the game ball to enter, so that the player is not frustrated.

  In addition, as described above, in the bullet ball game machine of the present invention having two start ports and two special symbol display devices, the following may be performed. As a mode of the big hit game, a normal mode and a special mode in which a game ball is difficult to enter are provided. In response, the jackpot game is executed in either a normal mode or a special mode. Then, when the second special symbol is variably displayed, it may be less likely that the hit type in which the big hit game becomes a special mode is generated than when the first special symbol is variably displayed.

  In the big hit game according to the special mode, it is difficult for the game ball to enter the big prize opening and it is not an advantageous game state for the player. I wish for. And, it is hard to generate a big hit game in a special mode when a game ball with a variable start port is inserted rather than a game ball with a fixed start port. Try to. However, if the variable starting port is not open, it is impossible to enter the game ball. Therefore, if the variable starting port does not open easily after the big hit game, the game ball enters the fixed starting port. Since the special hit game is likely to occur, the player may be annoyed. However, in the bullet ball game machine according to the present invention, when a winning hit occurs, the fluctuation time of the normal symbol is shortened until the big hit game ends. Therefore, even if the normal symbol variation display is started near the end of the big hit game, the normal symbol is immediately stopped and displayed, so that the variable start port can be opened. As a result, the player can continue the game as it is without irritating the game after the end of the big hit game.

A-3. Control circuit configuration:
Next, the configuration of the control circuit in the pachinko machine 1 of the present embodiment will be described. FIG. 6 is a block diagram illustrating a configuration of a control circuit in the pachinko machine 1 according to the present embodiment. As shown in the figure, the control circuit of the pachinko machine 1 is composed of a number of control boards, various boards, relay terminal boards, and so on. The main control board 200 that controls the success / failure involved, the sub-control board 220 that controls the effect of the game using the design symbols, lamps and sound effects, and the variable display device 27 under the control of the sub-control board 220 The effect control board 230 that performs the specific control of the game, the payout control board 240 that controls the operation of paying out the rented or winning balls, the launch control board 260 that controls the game ball, and the like. . These control boards include various types of CPUs, such as a CPU that executes various logical operations and calculation operations, a ROM that stores various programs and data executed by the CPU, and a RAM that stores temporary data when the program is executed. Peripheral LSIs are connected to each other via a bus. Further, the direction of the arrow shown in FIG. 6 represents the direction in which data or signals are input / output. In FIG. 6, only the CPU 201, ROM 202, and RAM 203 mounted on the main control board 200 are shown.

  As shown in the figure, the main control board 200 receives game ball detection signals from the first start port switch 17s, the second start port switch 17t, the big prize port switch 31s, the gate switches 36s and 37s, and the like. After determining whether or not it is related to the basic progression and winning balls, commands for instructing various operations are output to the sub-control board 220, the payout control board 240, the launch control board 260, and the like. In addition, the main control board 200 has a start opening solenoid 17m for opening and closing a pair of blade pieces provided in the second start opening 17b of the start opening unit 17 and a big prize for opening and closing the big prize opening 31d.

For example, when the player operates the ball lending switch 5b or the return switch 5c provided in the above-described upper plate part 5, this signal is transmitted from the ball lending display board 242 to the ball lending device 13 via the relay terminal board. Is done. The ball lending device 13 pays out a ball while exchanging data with the payout control board 240. When the main control board 200 outputs a prize ball payout command, the payout control board 240 receives this command and outputs a drive signal to the payout motor 109m to pay out the prize ball.

B. Overview of the game:
Next, an outline of a game performed in the pachinko machine 1 of the present embodiment having the above-described configuration will be briefly described.

  In the pachinko machine 1 of the present embodiment, a game is performed as follows. First, when a player throws a game ball into the recess of the upper plate portion 5 and rotates the launch handle 8, the game balls thrown into the upper plate portion 5 are supplied to the launcher unit 12 one by one, The game area 11 is fired as described above with reference to FIG. The strength at which the game ball is launched can be adjusted by the rotation angle of the launch handle 8, and the player can aim the game ball by changing the rotation angle of the launch handle 8.

  When the launched game ball passes either the normal symbol operation left gate 36 or the normal symbol operation right gate 37 provided on the left and right of the game area 11, the first symbol display provided on the lower left side of the variable display device 27 is displayed. In the device 28, the normal symbol variation display is started. As described above with reference to FIG. 4, the normal symbol display unit 29 is provided in the symbol display device 28, and the normal symbol display unit 29 is mounted with the normal symbol LED 29 a and the universal symbol hold display LED 29 b. Of these, the normal symbol LED 29a is used to display the variation of the normal symbol.

  FIG. 7A is an explanatory diagram conceptually showing a state in which normal symbols are variably displayed. In the pachinko machine 1 according to the present embodiment, the normal symbol LED 29a is repeatedly blinked to display the variation of the normal symbol. In the figure, the state in which the normal symbol LED 29a is lit is represented by a radial solid line, and the state in which the normal symbol LED 29a is lit is represented by a broken line. Then, after repeating blinking for a predetermined time, when the normal symbol LED 29a stops in a lighting state, it becomes a hit of the normal symbol, and the second start port 17b (starting below the start port unit 17 is started). Mouth) is open for a predetermined time. On the contrary, when it stops in the light-off state, it is out of the normal design and the second start port 17b does not open. As described above, in the pachinko machine 1 according to the present embodiment, the normal symbol is variably displayed by blinking the normal symbol LED 29a. Therefore, the normal symbol LED 29a of the present embodiment corresponds to the “normal symbol display device” in the present invention. Also, the time for the normal symbol to change display (ordinary symbol change time), and the time for the second start port 17b to be in the open state (start port open time) when the normal symbol is stopped and displayed in the hit symbol, It changes according to the state. This point will be described in detail later.

  Further, when the game ball passes the normal symbol operation left gate 36 or the normal symbol operation right gate 37 during the normal symbol variation display, the passage of this game ball is stored as the number of reservations, and the current normal symbol variation is stored. After the display is finished, the variable display is performed. Up to four normal symbols can be stored, and the number of stored normal symbols is displayed by the general symbol display LED 29b.

  FIG. 7B is an explanatory view showing a state in which the number of normal symbols held is displayed by the universal symbol hold display LED 29 b provided in the first symbol display device 28. When there is no normal symbol hold (that is, when the number of hold is zero), both of the two normal figure hold display LEDs 29b are turned off. When there is one hold, the left-hand general map hold display LED 29b remains off and the right-hand general map hold display LED 29b is lit. When there are two holds, the left-hand general map hold display LED 29b is lit in addition to the right-side normal map hold display LED 29b. Next, when there are three holds, the right-hand general map hold display LED 29b blinks and the left-hand general map hold display LED 29b lights. When the number of hold increases further to the upper limit of four, the left and right map hold display LEDs 29b blink. In this way, the normal symbol display unit 29 can display the number of holds from 0 to 4 by turning on, turning off, or blinking the two common figure hold display LEDs 29b.

  As described above with reference to FIG. 3A, the first symbol display device 28 is provided with the first special symbol display unit 30 so that the first special symbol can be variably displayed. Further, as shown in FIG. 3B, the second special symbol display unit 33 provided in the second symbol display device 32 can display the second special symbol in a variable manner. Of these, the first special symbol corresponds to the first start port 17a, the second special symbol corresponds to the second start port 17b, and the first special symbol or the second special symbol corresponds to the corresponding start port. When a game ball enters, the change display is started. As described above with reference to FIG. 5, when the second start port 17b is not open (normal state), the game ball does not enter the second start port 17b, so the second start port 17b is closed. In this state, the game ball mainly enters the first start port 17a and the first special symbol is displayed in a variable manner. Conversely, when the second start port 17b is in the open state, the game ball is moved to the first start port. Since it is easier to enter the second starting port 17b than 17a, the second special symbol is mainly variably displayed. Further, as described above, the first special symbol display unit 30 and the second special symbol display unit 33 have the same configuration, and accordingly, the first special symbol and the second special symbol change in the same manner. Display.

  FIG. 8 is an explanatory diagram conceptually showing a stop display mode of the first special symbol or the second special symbol. Since the first special symbol and the second special symbol have the same variation mode and stop display mode, they are simply referred to as special symbols without distinction between the two. As described above with reference to FIG. 3, each of the first special symbol display unit 30 and the second special symbol display unit 33 is composed of seven LEDs, and the special symbols are displayed by lighting them. As shown in FIG. 8, in the pachinko machine 1 according to the present embodiment, eight special symbol stop display modes are provided, and a unique lighting state is set for each stop display mode. As shown in the figure, in the pachinko machine 1 of the present embodiment, the stop display modes of the eight types of special symbols are roughly classified into four symbols. First, the stop display mode of the two special symbols shown at the top in the figure corresponds to the “normal hit symbol”, and the stop display mode of the two special symbols shown at the second level from the top is “probable hit”. Corresponds to “design”. In addition, the stop display mode of the two special symbols shown in the third row from the top corresponds to the “two round (2R) probability variation per symbol”, and the stop display mode of the two special symbols shown in the bottom row is the “off symbol”. Is equivalent to. In the first special symbol display unit 30 and the second special symbol display unit 33, each of the seven LEDs (the first special symbol LED 30a and the second special symbol LED 33a) blinks for a predetermined time to display the variation of the special symbol. When a predetermined time elapses, the display is stopped according to any stop display mode. Then, when one of the symbols “normal winning symbol”, “probable variation symbol” or “2R probability variation symbol” (so-called winning symbol) is stopped and displayed, the big winning game in which the big winning opening 31d is opened is started. Is done. The big hit game of the present embodiment is configured such that the round game in which the big winning opening 31d is opened is repeated a plurality of times.

  Among these, in the big hit game for the “normal hit symbol” or the “probable hit symbol”, the big winning opening 31d is opened in such a manner that the game ball can easily enter, so that the player can acquire a lot of game balls. It becomes an advantageous gaming state. On the other hand, in the jackpot game for the “2R probability variation symbol”, although the big winning opening 31d is opened, the opening mode is a mode in which the game ball is difficult to enter and opens only for a very short time. For this reason, game balls can hardly be acquired in some cases, and the big hit game may end without the player noticing.

  In addition, if the special symbol that has been variably displayed is stopped and displayed at either the 2nd or 3rd probability symbol shown in the top or the 2R probability variation symbol from the top of FIG. Until the next jackpot game occurs (for example, until a special symbol is displayed a predetermined number of times, etc.), the probability that the special symbol will win and stop display in the symbol is set to a high probability (so-called A probability variation state, or simply a probability variation state).

  In addition, even if a game ball has entered the first start port 17a or the second start port 17b, it is not possible to immediately start the variable display with the corresponding special symbol (for example, any special symbol is variable) In the case of being in the middle or in the case of a big hit game, etc.), the second starting port is entered into the first starting port 17a as the holding number of the first special symbol (the first special figure holding number). The entry into 17b is stored as the number of reserved special symbols (the number of second special figure reserved). The first special figure hold number is displayed by the first special figure hold display LED 30b, and the second special figure hold number is displayed by the second special figure hold display LED 33b. The manner in which the number of special symbols held using the first special figure hold display LED 30b or the second special figure hold display LED 33b is displayed is exactly the same as that of the general figure hold display LED 29b shown in FIG. The description is omitted here.

  In the pachinko machine 1 of the present embodiment, either the first special symbol LED 30a provided in the first symbol display device 28 or the second special symbol LED 33a provided in the second symbol display device 32 is shown in FIG. It is possible to variably display the eight types of special symbols shown in (1). Therefore, in this embodiment, the first special symbol LED 30a and the second special symbol LED 33a correspond to the “special symbol display device” in claim 1 of the present invention. Further, the first special symbol LED 30a that performs variable display corresponding to the first start port 17a corresponds to the “first special symbol display device” in claim 2 of the present invention, and corresponds to the second start port 17b. The second special symbol LED 33a that performs variable display corresponds to the “second special symbol display device” in claim 2 of the present invention.

  In accordance with the change display and stop display of the first special symbol or the second special symbol described above, the change display device 27 performs various effects using the effect symbols. FIG. 9 is an explanatory diagram illustrating an aspect of the effect performed by the variable display device 27. As described above with reference to FIG. 4, the three design symbols 27 a, 27 b, and 27 c are displayed on the liquid crystal display screen constituting the variable display device 27. When the special symbol variation display is started in either the first symbol display device 28 or the second symbol display device 32 described above, these three design symbols 27a, 27b, and 27c are simultaneously displayed on the variation display device 27. Start the variable display. In the present embodiment, a design is prepared by designing nine numbers from “1” to “9” as a design.

  FIG. 9A conceptually shows how the three design symbols 27a, 27b, and 27c are variably displayed at the same time. When a predetermined time elapses after the variable display is started, the left design symbol 27a is first stopped and displayed in any one of “1” to “9”, and then the right design symbol 27c is stopped and displayed. The medium design symbol 27b is stopped and displayed. The combination of the three design symbols 27a, 27b, and 27c that are stopped and displayed on the variable display device 27 is a special symbol (first special symbol) that is stopped and displayed on the first symbol display device 28 or the second symbol display device 32 described above. Or it is comprised so that it may interlock | cooperate with the stop display aspect of a 2nd special symbol. For example, when the first special symbol or the second special symbol stops at the winning symbol, the three design symbols 27a, 27b, and 27c of the variable display device 27 are stopped and displayed with the same symbol. In particular, when the first special symbol or the second special symbol stops at the above-described probability variation symbol, the three design symbols 27a, 27b, and 27c of the variable display device 27 are stopped and displayed at the same symbol representing an odd number. . When the first special symbol or the second special symbol stops at the 2R probability variation symbol, the three design symbols 27a, 27b, and 27c are stopped and displayed in a predetermined combination that does not align with the same symbol. Furthermore, when the first special symbol or the second special symbol is out of position and stopped with a symbol, any of the three design symbols 27a, 27b, and 27c that do not have the same symbol, except the combination of 2R probability variation symbols It is stopped and displayed in combination.

  As described above, the special symbols displayed on the first symbol display device 28 or the second symbol display device 32 and the three design symbols 27a, 27b, and 27c displayed on the variable display device 27 correspond to each other. When the changing first special symbol or the second special symbol is stopped and displayed, the three design symbols 27a, 27b and 27c are also stopped and displayed. Moreover, as shown in FIG. 2, the variable display device 27 is provided at a position that is more visible than the first symbol display device 28 and the second symbol display device 32, and the display screen is large and the display contents can be understood. Since it is easy, a player usually plays a game while looking at the screen of the variable display device 27. Therefore, when the left design symbol 27a initially stopped and displayed on the display screen of the variable display device 27 and the right design symbol 27c subsequently stopped and displayed are the same symbol, the stop design is finally displayed. The player pays attention to the change in the design so that the medium design design 27b may stop at the same design and enter a so-called jackpot gaming state. In this way, the effect of variably displaying the last design with the two design symbols stopped at the same design is called a reach effect, and it is possible to enhance the player's interest by performing the reach effect. It has become. The stop symbol corresponding to the 2R probability variation symbol is a combination of symbols in which the three design symbols 27a, 27b, and 27c are not aligned, similarly to the stop symbol corresponding to the off symbol.

C. Game machine control contents:
Below, in order to implement | achieve the game mentioned above, the control content which the pachinko machine 1 of a present Example is performing is demonstrated in detail.

C-1. Game control processing:
FIG. 10 is a flowchart showing a rough flow of a game control process performed by the CPU 201 mounted on the main control board 200 to control the progress of the game. As shown in the drawing, in the game control process, each of a prize ball related process, a normal symbol variation time setting process, a normal symbol game process, a second start opening return process, a special symbol game process, a special electric equipment game process, etc. The process is being executed repeatedly. The time required for one round of processing is about 4 msec. Therefore, these various types of processing are repeatedly executed about every 4 msec. Then, during these processes, various commands are transmitted from the main control board 200 to the various control boards including the sub control board 220. By doing so, the game of the entire pachinko machine 1 proceeds, and the sub-control board 220 controls the production in accordance with the progress of the game. The game control process performed by the CPU 201 mounted on the main control board 200 will be described below according to the flowchart.

  When starting the game control process, the CPU 201 mounted on the main control board 200 performs a process (pay ball related process) for paying out a game ball as a prize ball (S50). In such processing, among the various switches connected to the main control board 200, the switches related to the winning of the game ball (the first start port switch 17s, the second start port switch 17t, the big prize port switch 31s, etc.) It is detected whether or not a game ball has entered. When a game ball is detected, the number of prize balls to be paid out is calculated, and then a process for outputting a prize ball number designation command to the payout control board 240 is performed. When the payout control board 240 receives the award ball number designation command output from the main control board 200, the payout control board 240 interprets the content of the command, and according to the result, a drive signal is sent to the payout motor 109m mounted on the payout device (not shown). Is outputted to actually pay out the winning ball.

  When the CPU 201 of the main control board 200 performs the process related to the prize ball (S50), this time, it is determined whether or not the normal symbol game process is performed, that is, whether or not the normal symbol variation stop display is performed ( S100). Such a determination is made by detecting whether or not the second start port 17b is being opened. If the second start port 17b is not open, it is determined that the normal symbol game process is performed (S100: yes), and if the second start port 17b is open, it is determined that the normal symbol game process is not performed ( S100: no). If it is determined that the normal symbol game process is to be performed (S100: yes), the normal symbol variation time setting process (S120) is performed, and then the normal symbol game process described below is performed (S150). Here, the normal symbol variation time setting process (S120) is a process of setting a time for performing the normal symbol variation display with the normal symbol LED 29a shown in FIG. As will be described in detail later, in the pachinko machine 1 according to the present embodiment, the second start opening 17b does not readily open after the end of the big hit game by appropriately setting the fluctuation time of the normal symbol according to the gaming state. To avoid annoying players. On the other hand, when it is determined not to perform the normal symbol game process (S100: no), the normal symbol game process (S150) is skipped.

  In the normal symbol game process (S150), the following processes are mainly performed. First, it is determined whether or not the number of held ordinary symbols is present (whether it is “0”). If the number of retained symbols is present, whether or not the ordinary symbol is present is determined. Here, the reserved number of normal symbols is set when the game ball passes through the normal symbol operating gates 36 and 37, and in this embodiment, the upper limit value of the reserved number is set to “4”. Then, based on the determination result of the normal symbol, it is determined whether the normal symbol is to be stopped and displayed with the winning symbol (see FIG. 7C) or to be stopped with any other off symbol. Next, the normal symbol variation display is started, and the normal symbol variation display is continued until the variation time previously set in the ordinary symbol variation time setting process elapses. When the fluctuation time elapses, the normal symbol is stopped and displayed with the determined symbol. At this time, when the normal symbol is stopped and displayed, the start-port solenoid 17m is operated to activate the second symbol. By turning the pair of blade pieces 17w provided at the start port 17b outward, the second start port 17b is brought into an open state.

  In the pachinko machine 1 according to the present embodiment, whether or not a normal symbol is appropriate is determined to be a hit with a probability of 84/99. Therefore, when the normal symbol is variably displayed, in most cases, the second start port 17b is in an open state. The operation of opening the second start port 17b when the normal symbol is stopped and displayed as a symbol is performed while the CPU 201 of the main control board 200 executes the above-described normal symbol game process. Therefore, the CPU 201 mounted on the main control board 200 of this embodiment corresponds to the “starting port opening means” in the present invention.

  When the normal symbol game process is completed as described above, it is determined whether or not the second start port 17b is open (S190). If it is open (S190: yes), a process for returning the second start port 17b from the open state to the normal state (second start port return process) is performed (S200). On the other hand, if the second start port 17b is not open (S190: no), the second start port return process does not need to be performed and is skipped.

  In the second start port return process (S200), when any of the following conditions is satisfied, that is, the opening time of the second start port 17b has elapsed, or a prescribed number of games are stored in the second start port 17b. When any of the conditions for entering the ball is satisfied, a process of returning the opened second start port 17b to the normal state is performed. The opening time of the second start port 17b is set to about 0.5 seconds in a normal gaming state, but about 5 seconds (when the number of times of opening is 1) when the opening time extension function described later is activated. 1 is extended to about 5 seconds, or when the number of times of opening is plural, the total of the plural opening times is extended to about 5 seconds). On the other hand, when the opening time of the second start port 17b has not elapsed and the number of balls entering the second start port 17b has not reached the specified number, the second start port 17b is left open. 2 The start port return process (S200) is terminated.

  In the game control process, when returning from the second start port return process, the process related to the special symbol is started. In this process, after determining whether or not a predetermined condition for performing a special symbol game process described later is satisfied, if the predetermined condition is satisfied, the special symbol game process is started.

  FIG. 11 is a flowchart showing the first half of processing (special symbol game start determination processing) performed to determine whether or not to start special symbol game processing. FIG. 12 is a flowchart showing the latter half of the special symbol game start determination process. In determining whether or not to start the special symbol game process (S250), it is first determined whether or not a game ball has entered the first start port 17a (S252). As described above, the first start port 17a for detecting the entrance of a game ball is provided inside the first start port 17a, and it can be detected that a game ball has entered.

  When the game ball has entered the first start port 17a (S252: yes), it is determined whether or not the number of reserved special symbols has reached the upper limit (“4” in this embodiment). (S254). As described above with reference to FIG. 3A, the number of first special symbol reservations (first special figure reservation number) is displayed when the first special symbol display LED 30 b is lit on the first special symbol display unit 30. Has been. If the number of reserved special symbols does not reach the upper limit value (S254: no), the randomness determination random number for the first special symbol (first randomness determination random number), the symbol determination random number for the first special symbol ( 1st symbol determination random number) is acquired and stored in the RAM 203 of the main control board 200. Here, the first success / failure determination random number is a random number used to determine whether the first special symbol displayed on the first special symbol display unit 30 shown in FIG. The first symbol determination random number is a random number for determining the first special symbol to be stopped and displayed on the first special symbol display unit 30 according to the determination result of the first special symbol.

  When various random numbers for the first special symbol are acquired in this way (S256), the acquired various random numbers are stored in the RAM 203 as the first special symbol hold (first hold) (S258), and then stored in the first special symbol hold number. “1” is added (S260). Then, it is determined whether the newly generated hold is a hit hold (S262). This is the following process.

  As will be described in detail later, when a game ball enters the first starting port 17a, the first special symbol LED 30a of the first symbol display device 28 starts the variable display of the first special symbol, and the winning symbol or the off symbol is displayed. Is stopped and displayed. Whether the winning symbol or the winning symbol is stopped and displayed is determined at the time of starting the variation of the special symbol, based on the first success / failure random number acquired when the game ball enters the first starting port 17a. Here, in the pachinko machine 1 according to the present embodiment, whether or not the hold is determined is determined based on the first randomness determination random number acquired as the hold not only when the change of the symbol starts but also when a new hold occurs. To do. The determination method is performed in the same manner as when the special symbol starts to change. That is, the ROM 202 of the main control board 200 is preliminarily set with a random number value (winning value) to which the winning / failing determination result is hit. The “hit value” is compared, and if they match, it is judged as “hit” (ie, hit hold), and “other” (ie, hold off) is determined otherwise. As will be described later, in the state where the probability changing function is operating (probability changing state), the “hit value” increases, and as a result, the hit is likely to occur.

  As a result of determining whether or not the first hold is successful as described above (S262), when it is determined that the first hold is a hit hold (S262: yes), “1” is added to the hit hold counter ( S264). Here, the winning hold counter is a counter indicating the number of winning holds among the winning / failure determination random numbers (including a second success / failure determination random number described later) stored as the hold. The hit hold counter is assigned a predetermined address of the RAM 203 mounted on the main control board 200, and in S264, a process of adding “1” to the data of the predetermined address of the RAM 203 is performed. On the other hand, when it is determined that the first hold is not a hit hold (S262: no), the process of adding “1” to the hit hold counter is not performed.

  The processing when the game ball enters the first start port 17a (S252: yes) and the number of the first special symbols on hold has not reached the upper limit “4” (S254: no) has been described. . On the other hand, when the game ball does not enter the first start port 17a (S252: no), or when the number of the first special symbol hold has reached the upper limit “4” (S254: yes) immediately starts the process related to the second special symbol hold (second hold) described below without performing the above-described series of processes related to the hold of the first special symbol (first hold).

  In the process related to the second special symbol hold (second hold), first, it is determined whether or not a game ball has entered the second start port 17b (S266 in FIG. 12). If a game ball has entered the second start port 17b (S266: yes), whether or not the number of second special symbols held (second special figure holding number) has reached the upper limit “4”. If the upper limit has not been reached (S268: no), the randomness determination random number for the second special symbol (second randomness determination random number), the symbol determination random number for the second special symbol (second) After obtaining the symbol determination random number (S270) and storing it in the RAM 203 of the main control board 200 as the second special symbol hold (second hold) (S272), the second special symbol hold number (second special symbol) "1" is added to the figure hold count) (S274). Then, similarly to the case of the first hold described above with reference to FIG. 11, it is determined whether or not the newly acquired second hold is a hit hold (S276). That is, it is determined whether or not the second success / failure random number acquired as the second hold matches the winning random number (winning value) set in the ROM 202 of the main control board 200. If the value matches the winning value, it can be determined that the hold is a winning hold, and if it does not match the winning value, the hold is a missed hold.

  As described above, whether or not the second hold is a hit hold is determined (S276). As a result, if the second hold is a hit hold (S276: yes), "1" is added to the hit hold counter. (S278). That is, as described above, even when a hit hold occurs in the first hold (S262 in FIG. 11: yes) and a hit hold occurs in the second hold (S276 in FIG. 12), the same hold hold counter is set. “1” is added. On the other hand, when it is determined that the second hold is not a hit hold (S276: no), the process of adding “1” to the hit hold counter is not performed.

  The process when the game ball enters the second start port 17b (S266: yes) and the number of reserved special symbols has not reached the upper limit “4” (S268: no) has been described. . On the other hand, when the game ball does not enter the second start port 17b (S266: no), or when the number of reserved special symbols reaches the upper limit “4” (S268: yes) does not perform the above-described series of processing regarding the second special symbol hold (second hold).

  When a game ball enters the first start port 17a or the second start port 17b, a first determination symbol random number (first determination symbol random number) or a second special symbol determination random number ( The process of acquiring the second success / failure determination random number) is performed by the CPU 201 mounted on the main control board 200 of the present embodiment executing the special symbol game start determination process described above. Therefore, the CPU 201 of the main control board 200 of this embodiment corresponds to the “determination random number acquisition unit” in the present invention. In addition, the process of storing the acquired first or second determination random number or second determination random number as the first hold or the second hold and determining whether or not the hold is a hit hold is also performed by the CPU 201 of the main control board 200. However, this is performed by executing the above-described special symbol game start determination process. Therefore, the CPU 201 of the main control board 200 of the present embodiment corresponds to the “hold storage unit” and “hold hold determination unit” in the present invention.

  As described above, when the series of processes related to the first hold and the series of processes related to the second hold are completed, it is determined whether or not the jackpot game is being executed (S280). The special symbol game process to be described later is a process for starting the big hit game when the first special symbol or the second special symbol is variably displayed and a predetermined winning symbol is stopped and displayed in any special symbol. If a big hit game is currently being played, there is no need to repeatedly start a big hit game. Therefore, when the processing related to the first hold or the second hold described above is completed, it is determined whether or not the big hit game is being played (S280). If the big hit game is not being set (S280: no), it will be described later. It is determined that the special symbol game process is started (that is, S250: yes). On the other hand, if the game is already a big hit game (S280: yes), it is determined that the special symbol game process is not started (that is, S250: no).

  As described above, when it is determined that the special symbol game process is to be performed (S250: yes), the special symbol game process described below is performed (S300). On the other hand, if it is determined not to perform the special symbol game process (S250: no), the special symbol game process (S300) is skipped.

C-2. Special design game processing:
13 and 14 are flowcharts showing the flow of the special symbol game process of the present embodiment. When the special symbol game process of this embodiment is started, first, it is determined whether either the first special symbol or the second special symbol is changing (S302). As described above with reference to FIG. 3, the pachinko machine 1 of the present embodiment is provided with the first symbol display device 28 and the second symbol display device 32, and the first symbol display device 28 has the first special symbol. Variation display is possible, and the second symbol display device 32 allows variation display of the second special symbol.

  When neither the first special symbol nor the second special symbol is changing (S302: no), it is during the time for displaying the first special symbol or the second special symbol as a stop symbol (the special symbol stop display time). Whether or not (S304). That is, for both the first special symbol and the second special symbol, the stop display time is provided as the confirmation time for the symbol that has been stopped for a while after the change display of the special symbol is finished. It is determined whether or not it is during the display time. When it is confirmed that the first special symbol and the second special symbol are not variably displayed and the special symbol stop display time has elapsed (S304: no), the number of reserved second special symbols (first It is determined whether or not (2 special figure hold count) is “0” (S306). As described above, in the pachinko machine 1 of this embodiment, two special symbols, the first special symbol and the second special symbol, are provided, and the number of holdings corresponding to each is provided. Confirm the number of second special symbols held (second special figure number). If the second special figure hold number is not “0”, in other words, if the second hold remains (S306: no), the second success / failure determination random number and the second symbol determination stored in the RAM 203 are determined. The random number stored at the earliest timing is read from the random numbers (S308), and the second special symbol related process described later is started (S310).

  On the other hand, when it is determined that the second special figure hold number is “0” (S306: yes), it is determined whether the first special figure hold number is “0” (S326), and If the first hold remains (S326: no), the random number stored at the earliest timing is read out from the first randomness determination random number and the first symbol determination random number stored in the RAM 203 ( S328), first special symbol related processing described later is started (S330). As described above, the first special figure reservation number is determined only when the second special figure reservation number is “0”, so whether or not the second special symbol reservation is left is determined. While it remains, the success / failure determination random number and the symbol determination random number for the second special symbol are read, and the first special symbol-related process is not performed. In other words, the second special figure reservation number is determined to have priority over the first special figure reservation number.

C-2-1. Second special symbol related processing:
FIG. 15 is a flowchart showing the flow of the second special symbol related process. As described above, this process is a process that is started after the second winning / failing determination random number and the second symbol determining random number are read out in the special symbol game process. As shown in the drawing, when the second special symbol related process (S310) is started, first, a determination as to whether or not the second special symbol is true is made (S312).

  FIG. 16 is a flowchart showing a flow of processing for determining whether or not the second special symbol is correct (second special symbol determination processing). As shown in the figure, when the second special symbol success / failure determination process (S312) is started, first, it is determined whether or not the probability variation flag is ON (S3120). Here, the probability variation flag is a flag indicating whether or not the current gaming state is a probability variation state, and a predetermined address in the RAM 203 of the main control board 200 is set as a data area for setting the probability variation flag. As will be described later, when the big hit game is generated in any of the above-mentioned "probability change symbol" or "2R probability change symbol", the probability change flag is set to ON after the big hit game ends. The gaming state becomes a certain change state. If the probability variation flag is ON (S3120: yes), the probability determination table for probability variation is selected (S3122). If the probability variation flag is not ON (S3120: no), the probability determination table for non-probability variation is selected. (S3124). Here, the success / failure determination table is a table in which the determination result of the special symbol is determined in association with the random determination random number of the special symbol, and is stored in advance in the ROM 202 of the main control board 200. In the pachinko machine 1 according to the present embodiment, the first special symbol and the second special symbol are provided, and the randomness determination random number is stored for each of them. The same table is used for any success / failure random number of the second special symbol. Correspondingly, in this specification, the success / failure determination table of either the first special symbol or the second special symbol is simply referred to as a special symbol's success / failure determination table.

  FIG. 17 is an explanatory diagram illustrating a special symbol determination table stored in the pachinko machine 1 according to the present embodiment. FIG. 17A shows a non-probability change determination table, and FIG. 17B shows a probability change determination table. As shown in the drawing, in the success / failure determination table, a success / failure determination result of “win” or “out” is set in association with the random determination random number of the first special symbol or the second special symbol. Further, as is clear from the comparison between FIG. 17A and FIG. 17B, the probability variation determination table shown in FIG. 17B is the non-probability variation table shown in FIG. “Win” determination result is set to a larger number of random numbers than the determination table.

  In the second special symbol success / failure determination process shown in FIG. 16, when a corresponding determination table is selected according to whether or not the current gaming state is being probabilistically changed, the special symbol game processing is read first. Based on the second success / failure determination random number, it is determined whether or not the determination result of the second special symbol is “winning” by referring to the selected probability determination table for probability variation or non-probability variation (S3126). . As described above, the success / failure determination table for probability change that is referred to in the probability variation state is more or less a success / failure determination for the number of success / failure determination random numbers than the failure determination table for non-probability variation that is referred to when not in the probability variation state. Since the result is set, the success / failure determination result of “hit” is generated during probability change with higher probability than during non-probability change.

  If the determination result of the second special symbol is determined to be a win (S3126: yes), refer to a table (second special symbol hit symbol table) for determining the hit symbol of the second special symbol. The winning symbol is determined (S3128). FIG. 18 is an explanatory diagram illustrating a second special symbol per symbol table. As shown in the figure, in the second special symbol per symbol table, various hit symbols are set in association with the second symbol determined random number, and based on the second symbol determined random number, the second special symbol per symbol is set. By referring to the symbol table, the winning symbol of the second special symbol can be determined. For example, when the second symbol determination random number is in the range of 0 to 63, it is determined as the probability variation per symbol of which only one LED is lit among the two types of “probability per symbol”. As shown in the second special symbol per symbol table of FIG. 18, the second symbol determination random number is not set to “2R probability variation per symbol”. Therefore, when the winning symbol is stopped and displayed in the second special symbol, either “probable hitting symbol” or “normal winning symbol” is always stopped and displayed.

  In addition, as shown in the second special figure hit symbol table of FIG. 18, in the case of probability change or normal hit, the number of rounds is set to 15 and a big hit game of 15 rounds is performed. The number of rounds is set to 2 in the case of probability variation. For this reason, if 2R probability variation occurs, the number of rounds in the big hit game is reduced to two. Moreover, in the big hit game with 2R probability variation, one round is completed in a very short time, so even if the big hit game occurs, the player can hardly receive the payout of the game ball and the big hit game is played. It ends. The aspect of the jackpot game by 2R probability variation corresponds to the “special aspect” jackpot game in claim 3 of the present invention. In the determination of success / failure for the second special symbol, the 2R probability variation that is not so advantageous for the player does not occur in this way, and it is possible to receive the payout of the game ball sufficiently, and the probability variation that is more advantageous for the player. Or it usually occurs only per hit. For this reason, whether or not the above-mentioned second special symbol is performed when a game ball enters the second start port 17b is used as a trigger to be described later when a game ball enters the first start port 17a. The determination of success / failure is made under conditions that are more advantageous to the player than the determination of success / failure of one special symbol.

  On the other hand, the case where it is determined that the determination result of the second special symbol is a win (S3126: yes in FIG. 16) has been described, but if the result of determination is incorrect (S3126: no), the second With reference to a table for determining a special symbol out-of-design (second special symbol out-of-design table), a special symbol is determined (S3130). As described above with reference to FIG. 8, in the pachinko machine 1 according to the present embodiment, two types of outlier symbols are set, and the second special symbol outlier symbol table has a random value for each outlier symbol. Are associated. Therefore, in S3130, the random symbol for determining the off symbol can be acquired and the out symbol of the second special symbol can be determined by referring to the second off symbol table for special symbol. Instead of acquiring a random number for determining the off symbol, the out symbol may be determined using the second symbol determining random number acquired for determining the winning symbol.

  As described above, in the determination process for the second special symbol shown in FIG. 16, whether or not the second special symbol is determined based on the second determination result random number is determined, and the second determination is determined according to the determination result. 2. A process of determining a winning symbol or a missing symbol of the special symbol is performed (S3126 to S3130). When the winning symbol or the off symbol is determined, the second special symbol success / failure determination process is terminated, and the process returns to the second special symbol game process shown in FIG.

  As shown in FIG. 15, in the second special symbol game process, after returning from the second special symbol success / failure determination process, a process of setting a variation pattern of the second special symbol is performed (S314). Here, the variation pattern of the second special symbol is as follows. As described above, in the second symbol display device 32, when the variation display of the second special symbol is started, the variation display is performed for the set variation time, and then the stop display is performed with the predetermined hit symbol or the off symbol. Is done. In addition, in accordance with the variation display of the second special symbol, the variation display device 27 performs various effects while variably displaying the design symbols 27a, 27b, and 27c, and the second special symbol is stopped and displayed. The variation of the design symbols 27a, 27b, and 27c is stopped and displayed, and the symbols corresponding to the stopped symbols of the second special figure are stopped and displayed. That is, the contents of various effects performed using the design symbols 27a, 27b, and 27c on the variation display device 27 depend on the stop symbol and variation time of the second special diagram. Therefore, when the stop symbol of the second special symbol is determined by the above-described determination process of the second special symbol with reference to FIG. 16, the time (variation time) during which the second special symbol is variably displayed is subsequently determined. There is a need. The variation pattern of the second special symbol is a pattern representing a variation time during which the second special symbol is variably displayed. When the time reduction flag described later is set to ON, the variation time is set to a variation time shorter than the normal time.

  When the variation pattern of the second special symbol is set (S314), the variation display of the second special symbol is started (S316), and then the second special symbol hold displayed by using the second special symbol hold display LED 33b. A process of subtracting 1 from the number is performed (S318). Next, after outputting the command (variation pattern designation command) for designating the variation pattern of the second special symbol determined previously to the sub-control board 220 (S320), the special symbol stop symbol (here, A command for designating the stop symbol of the second special symbol (stop symbol designating command) is also output to the sub-control board 220 (S322), and the second special symbol related process of FIG. 15 is terminated, and FIG. Return to the special symbol game process shown in.

  As described above, when it is determined that the second special symbol is retained in the special symbol game process (S306: no in FIG. 13), whether or not the second special symbol is determined is determined and the variation display of the second special symbol is performed. A series of processes (second special symbol game related processes) for starting the game has been described. On the other hand, if it is determined that the second special symbol hold does not remain (S306: yes), it is determined whether or not the first special symbol hold remains (S326). Then, when the first special symbol is retained (S326: no), it is stored at the earliest timing among the first success / failure determination random number and the first symbol determination random number stored in the RAM 203. After reading the random number (S328), the first special symbol related process described below is started (S330).

C-2-2. First special symbol related processing:
FIG. 19 is a flowchart showing the flow of the first special symbol related process. Since the first special symbol related process is substantially the same as the second special symbol related process described above with reference to FIG. 15, the first special symbol related process will be briefly described based on the description of the second special symbol related process. Also in the first special symbol related process, as in the second special symbol related process described above, when the process is started, first, whether or not the first special symbol is determined is determined (S332). The determination of whether or not the first special symbol is successful is performed in substantially the same manner as the determination of whether or not the second special symbol is already described with reference to FIG. Hereinafter, a brief description will be given with reference to FIG. 16. First, it is determined whether or not the probability variation flag is set to ON. If the probability variation flag is set to ON (S3120: equivalent to yes), the probability variation is determined. Is selected (equivalent to S3122), and if the probability variation flag is not ON, a non-probability variation determination table is selected (corresponding to S3124). As the success / failure determination table referred to at this time, as described above, the special symbol determination / rejection determination table shown in FIG. 16 can be used.

  Next, a process of determining a winning symbol of the first special symbol is started if the determination result is a win, and conversely if the determination result is not positive, a process of determining a losing symbol of the first special symbol is started. That is, when the determination result is a winning (S3126: equivalent to yes), the winning symbol of the first special symbol is determined by referring to the first special symbol winning symbol table (corresponding to S3128). On the other hand, when the result of the determination is wrong (corresponding to S3126: no), the first special symbol outlier symbol is determined with reference to the first special symbol outlier symbol table (corresponding to S3130).

  FIG. 20 is an explanatory view exemplifying a first special symbol winning symbol table which is referred to when determining the first special symbol winning symbol. Similarly to the second special symbol per symbol table described above with reference to FIG. 18, various hit symbols are set in the first special symbol per symbol table in FIG. 20 in association with the first symbol determination random number. The winning symbol of the first special symbol can be determined based on the first symbol determining random number. As is apparent from a comparison between the second special symbol per symbol table in FIG. 18 and the first special symbol per symbol table in FIG. 20, the first special symbol per symbol table includes “2R probability variation”. The first symbol determination random number is set for all the winning symbols including “winning symbol”. Therefore, when the winning symbol is stopped and displayed in the first special symbol, not only the “probable variation symbol” or “normal winning symbol” but also the “2R probability variation symbol” may be stopped and displayed. Therefore, the determination of whether or not the first special symbol described above is performed when the game ball enters the first start port 17a is used as a trigger when the second game described above is performed when the ball enters the second start port 17b. This means that the determination of success / failure is performed under a disadvantageous condition for the player rather than the determination of success / failure of the special symbol.

  As described above, in the first special symbol determination process (S332), the first special symbol is determined based on the first determination symbol, and the first special symbol is determined according to the determination result. A process of determining a symbol winning symbol or a symbol falling out is performed. When the winning symbol or the off symbol is determined, the first special symbol success / failure determination process is terminated, and the process returns to the first special symbol game process shown in FIG.

  Next, also in the first special symbol related process shown in FIG. 19, the variation pattern setting process of the first special symbol is performed in the same manner as the second special symbol related process (see FIG. 15) described above (S334). Even when the variation pattern of the first special symbol is set, the variation time is set to a variation time shorter than that of the normal time when the time flag to be described later is set to ON. Thereafter, after the variable display of the first special symbol is started (S336), a process of subtracting 1 from the reserved number for the first special symbol displayed on the first special symbol hold display LED 30b is performed (S338). Next, after outputting a command (variation pattern designation command) for designating the variation pattern of the first special symbol determined previously to the sub-control board 220 (S340), a special symbol stop symbol (here, A command for designating the stop symbol of the first special symbol (stop symbol designating command) is also output to the sub-control board 220 (S342), and the first special symbol-related process of FIG. 19 is terminated, and FIG. Return to the special symbol game process shown in.

  The CPU 201 of the main control board 200 determines the variation pattern and stop symbol of the first special symbol or the second special symbol as described above, and directs the variation pattern designation command and the stop symbol designation command to the sub-control board 220. Is output, the special symbol game process shown in FIG. 13 is terminated and the process returns to the game control process shown in FIG. Note that the process of determining whether or not the game is successful based on the first success / failure determination random number acquired when the game ball enters the first start port 17a is executed in the first special symbol related process of FIG. . Similarly, the process for determining whether or not the game is successful based on the second randomness determination random number acquired when the game ball enters the second start port 17b is executed in the second special symbol related process of FIG. Yes. Since the first special symbol-related process and the second special symbol-related process are executed by the CPU 201 of the main control board 200, the CPU 201 of the main control board 200 of the present embodiment is the “appropriateness determination unit” in the present invention. It corresponds to.

  The detailed process performed in the special symbol game process when either the first special symbol or the second special symbol is not variably displayed (that is, S302: no in FIG. 13) has been described above. On the other hand, when the special symbol game process of FIG. 13 is started while either the first special symbol or the second special symbol is fluctuating, “yes” is determined in the determination of S302 performed first. This case corresponds to the case where the variation pattern of the special symbol and the stop symbol are already determined and the variation of the first special symbol or the second special symbol is started. Therefore, it is determined whether or not the special symbol variation time has elapsed (S348). That is, since the variation time of the first special symbol or the second special symbol is determined in advance according to the variation pattern, by setting the timer at the same time as starting the variation of the first special symbol or the second special symbol, It is determined whether or not the fluctuation time has elapsed. If the variation time has not yet elapsed (S348: no), the special symbol game process is terminated as it is, and the process returns to the game control process shown in FIG.

  On the other hand, if it is determined that the variation time has elapsed (S348: yes), a command (design stop command) indicating that the special symbol being varied is to be stopped and displayed is output to the sub-control board 220. Along with (S350), the first special symbol or the second special symbol that is being displayed in a variable manner is stopped and displayed at a preset symbol (S352). Next, after setting a time (stop display time) for holding the special symbol displayed in a stopped state in a stopped state (S354), it is determined whether or not the set stop display time has passed (S356). If the stop display time has not elapsed (S356: no), the special symbol game process is terminated as it is, and the process returns to the game control process shown in FIG.

  On the other hand, when the stop display time has elapsed (S356: yes), it is determined whether or not the stop-displayed symbol is a winning symbol (S358 in FIG. 14). The pachinko machine 1 according to the present embodiment is equipped with two symbol display devices, a first symbol display device 28 and a second symbol display device 32. In the first symbol display device 28, the first special symbol changes. Display and stop display are possible, and the second symbol display device 32 can display variation and stop display of the second special symbol, but the winning symbol is either the first special symbol or the second special symbol. The stop may be displayed.

  When the symbol stopped and displayed on either the first symbol display device 28 or the second symbol display device 32 is a winning symbol (S358: yes), the number of rounds and the opening time of the special winning opening 31d are set. (S360). As described above, the number of rounds is set to 15 when the hit type is normal, and the probability variation is set to 15, and is set to 2 when the probability is 2R probability variation. The opening time of the special winning opening 31d is set to an extremely short time (for example, 0.5 seconds) in the case of 2R probability variation. Next, the big hit flag is set to ON (S362). The big hit flag is a flag indicating that the gaming state is a big hit gaming state, and a predetermined address of the RAM 203 mounted on the main control board 200 is used as a data area for setting the big hit flag. As will be described in detail later, when the jackpot flag is set to ON, when the special symbol game process is exited and the game control process of FIG. It has become so.

  In the pachinko machine 1 according to the present embodiment, the probability variation function and the time-shortening function do not work during the big hit game. Here, the probability variation function is a function for setting a high probability of winning in the determination of whether or not a special symbol is successful, and the time reduction function is a variation of the special symbol in the first symbol display device 28 or the second symbol display device 32. This function shortens the displayed time. In the pachinko machine 1 of the present embodiment, the probability variation function is activated when the probability variation flag is set ON, and the time reduction function is activated when the time reduction flag is set ON. Similarly to the big hit flag, the probability variation flag and the time reduction flag also use predetermined addresses of the RAM 203 mounted on the main control board 200 as data areas for setting the probability variation flag and the time reduction flag, respectively.

  If the big hit flag is set to ON in S363 in FIG. 14, it is determined whether or not the probability variation flag is set to ON (S363). If the probability variation flag is set to ON (S363: yes), since the probability variation function and the time shortening function are operating, in order to stop these functions, the probability variation flag is set to OFF (S364), The time reduction flag is set to OFF (S366). On the other hand, when the probability variation flag is not set to ON (S363: no), it is subsequently determined whether or not the hourly flag is set to ON (S365), and the hourly flag is set to ON. In this case (S365: yes), the time reduction flag is set to OFF (S366). Further, in the pachinko machine 1 according to the present embodiment, when the time reduction function is activated, the function (opening time extension function) for extending the opening time of the second start port 17b is also activated. If the time reduction flag is turned off to stop the operation (S366), the opening time extension flag is set to OFF to stop the operation of the opening time extension function (S368), and then the special symbol game shown in FIG. 13 and FIG. Exiting the process, the process returns to the game control process of FIG. On the other hand, if the game state when the jackpot flag is set to ON is neither probable change nor short time (S365: no), the special symbol game process is exited and the game control process is resumed.

  The process when the symbol stopped on the first symbol display device 28 or the second symbol display device 32 (that is, the first special symbol or the second special symbol) is a winning symbol (S358: yes) has been described above. However, if the symbol that has been stopped and displayed is not a winning symbol (is a missing symbol) (S358: no), the following processing is performed.

  First, it is determined whether or not the time reduction flag is ON (S372). If it is determined that the time reduction flag is ON (S372: yes), the number of fluctuations of the special symbol during the time reduction is counted (S374), and then the number of fluctuations is set to cut the time reduction. It is determined whether or not the predetermined number of short-time games has been reached (S376). As will be described later, in the pachinko machine 1 of this embodiment, when the big hit game ends, the number of hourly games is set, and when the big hit game is based on normal hits, the number of hourly games is set to 100, If it is due to probability variation (including 2R probability variation), the number of short-time games is set to 10,000. When the number of fluctuations reaches the predetermined number of short-time games (S376: yes), the short-time flag is turned off (S378), the opening time extension flag is also turned off (S368), and shown in FIGS. Exit the special symbol game process and return to the game control process of FIG.

  The first special symbol LED 30a of the first symbol display device 28 or the second special symbol of the second symbol display device 32 in response to the game ball entering the first starting port 17a or the second starting port 17b. The CPU 201 mounted on the main control board 200 of the present embodiment performs the process of starting the special symbol variation display with the LED 33a and stopping and displaying the special symbol according to the determination result of the special symbol. This is realized by executing the special symbol game process shown in FIG. 13 and FIG. Therefore, in this embodiment, the CPU 201 of the main control board 200 corresponds to the “special symbol variation control means” in the present invention.

  As shown in FIG. 10, in the game control process, when returning from the special symbol game process, it is determined whether or not the big hit flag is set to ON (S390). As described above, the big hit flag is a flag indicating that the gaming state is the big hit gaming state. Therefore, when the big hit flag is set to ON (S390: yes), the CPU 201 of the main control board 200 starts the special electric accessory game process described below (S400). On the other hand, if the big hit flag is not set to ON (S390: no), the special electric game game process (S400) is skipped and the process returns to the top of the game control process, and the above-mentioned prize ball related process (S50) The following series of processing is repeated.

C-3. Special electric game game processing:
FIG. 21 is a flowchart showing the first half of the special electric accessory game process. FIG. 22 is a flowchart showing the latter half of the special electric accessory game process. A special game (so-called big hit game) is performed by executing the special electric accessory game process. Hereinafter, the special electric accessory game process will be described with reference to FIG. 21 and FIG. 22, but as a preparation, the contents of a game called a jackpot game will be briefly described.

  As described above with reference to FIG. 2, a special winning opening 31d is provided below the game board, and the special winning opening 31d is closed in a normal gaming state. However, when the big hit game is started, the big winning opening 31d is opened. Since the big winning opening 31d opens larger than the other winning openings, when the big winning opening 31d is in an open state, the game ball will be entered with a high probability unless the big hit game is based on 2R probability variation. Become. The opened large winning opening 31d is once closed when a predetermined opening time elapses or a predetermined number of game balls enter, but is again opened when a predetermined closing time elapses. The game from the opening of the special winning opening 31d to the closing is referred to as “round game (or simply round)”. When such round games are repeated and a predetermined number of round games are consumed, the big hit game ends. Hereinafter, the special electric accessory game process performed by the CPU 201 of the main control board 200 in order to execute the above-described jackpot game will be described with reference to FIGS. 21 and 22.

  When the CPU 201 of the main control board 200 starts the special electric accessory game process (S400), it is first determined whether or not the special winning opening 31d is open (S402). The big prize opening 31d is closed in a normal gaming state, and therefore, the big prize opening 31d is in a closed state immediately after the start of the big hit game. Accordingly, it is determined that the special winning opening 31d is not open (S402: no), and it is determined whether or not the number of openings (that is, the number of rounds) of the special winning opening 31d has reached a predetermined number (S404). As described above, during the big hit game, the big winning opening 31d is opened, and a predetermined number of round games are repeated. Corresponding to this, when the special winning opening 31d is closed (S402: no), it is determined whether or not the number of times of opening (the number of rounds) of the special winning opening 31d has reached a predetermined number (S404). .

  As a matter of course, immediately after the big hit game is started, the number of opening of the big prize opening 31d has not reached the predetermined number (S404: no), so it is determined whether or not the closing time of the big prize opening 31d has elapsed. (S406). The closing time of the special winning opening 31d is a time during which the special winning opening 31d is in a closed state between rounds. Immediately after the big hit game is started, the big prize opening 31d is in a closed state, so it is naturally determined that the closing time of the big prize opening 31d has passed (S406: yes), and the big prize opening 31d is opened. The game is opened and a new round game is started (S408). And after outputting the command (round number designation | designated command) which designates what round game the started round game is to the sub-control board 220 (S410), the special electric game game process shown in FIG. Is temporarily terminated and the process returns to the game control process of FIG.

  When the CPU 201 of the main control board 200 returns to the game control process, as shown in FIG. 10, after performing a series of various processes after the prize ball related process (S50), the special electric game game process (S400) again. To start. As described above, the time required for the CPU 201 of the main control board 200 to execute the game control process shown in FIG. 10 once is about 4 msec. Therefore, the special electric accessory game process shown in FIGS. 21 and 22 is also executed about every 4 msec. When the special game is started and the special electric accessory game process of FIG. 21 and FIG. 22 is executed for the first time, as described above, the special winning opening 31d is opened in S408, and the process is ended as it is. However, when the second round of processing is performed after about 4 msec, it is determined in S402 that the special winning opening 31d is being opened (S402: yes).

  Next, it is determined whether or not the opening time of the special winning opening 31d has reached a predetermined time (S412). As described above, in the big hit game, the big winning opening 31d is opened, but is closed when the opening time reaches a predetermined time or when a predetermined number of game balls enter the big winning opening 31d. In response to this, in S412, it is determined whether or not the opening time of the special winning opening 31d has reached a predetermined time. If the opening time has reached the predetermined time (S412: yes), after closing the special prize opening 31d (S416), the special electric game game process shown in FIG. 21 is exited, and the game control of FIG. Return to processing. On the other hand, if the opening time has not reached the predetermined time (S412: no), it is determined whether or not the number of game balls that have entered the special winning opening 31d has reached a specified number (S414). When the number of game balls reaches the specified number (S414: yes), the special winning opening 31d is closed (S416). On the other hand, when the prescribed number has not been reached (S414: no), the opening time of the special winning opening 31d has not yet reached the predetermined time, and the number of game balls that have entered the special winning opening 31d is also the prescribed number. Therefore, the special electric accessory game process shown in FIG. 21 is exited and the game control process shown in FIG. 10 is resumed while the special winning opening 31d is kept open.

  While the game control process of FIG. 10 is repeatedly executed, whether the opening time of the big prize opening 31d reaches a predetermined time (S412: yes), or a prescribed number of game balls are in the big prize opening 31d. A ball is entered (S414: yes), and the special winning opening 31d is closed (S416). Thus, one round game is completed. Then, when the special electric accessory game process is executed next, it is determined in S402 that the special winning opening 31d is closed (S402: no), and it is determined whether or not a predetermined number of round games have ended (S404). ), If all the round games have not ended (S404: no), after confirming that the closing time of the big prize opening has reached a predetermined time (S406: yes), the big prize opening 31d is again opened. After starting a new round game (S408), a round number designation command is output toward the sub-control board 220 (S410). On the other hand, if it is determined in S404 that the predetermined number of round games have ended (S404: yes), the big hit flag is changed to OFF to end the big hit game (S418). When the big hit game is started by 2R probability change, the number of rounds is set to 2 and the big prize opening time is set to about 0.5 seconds (see S360 in FIG. 14). Although it is in an open state, almost no game ball can be entered, so that the big hit game ends without receiving the payout of the game ball.

  When the big hit game is terminated as described above, it is determined whether or not the type of hit that is to start the big hit game is a probability variation (including 2R probability variation) (S422 in FIG. 22). If there is no chance of winning (S422: no), it means that the game is a big hit game with a normal hit, so the number of time reductions is set to 100 (S424). On the other hand, when the big hit game is based on the probability variation (including 2R probability variation) (S422: yes), after setting the number of time reductions to 10,000 times (S425), the probability variation flag is set to ON. (S426).

  In this way, according to the type of winning that the big hit game is to be started, the number of time reductions is set (S424, S425), or the process of setting the probability variation flag to ON is performed (S426), then the big hit game is continued. In order to activate the time-shortening function and the opening extension function of the ordinary electric accessory after the end of, the time-shortening flag and the opening extension flag are set to ON (S428, S430).

  When all the processes related to the big hit game are completed as described above, finally, “1” is subtracted from the hit hold counter (S432). The winning hold counter is acquired along with the game ball entering the first start port 17a or the second start port 17b in the special symbol game start determination process described with reference to FIGS. This counter is incremented by “1” each time the first success / failure determination random number or the second success / failure determination random number determined to be a win (see S264 in FIG. 11 and S278 in FIG. 12). Prior to that, the fact that the big hit game was performed means that “1” should have been added to the hit hold counter in either S264 of FIG. 11 or S278 of FIG. “1” is subtracted from the counter. As a result, a new winning hold is generated after the first winning determination random number or the second winning determination random number holding on which the big hit game is started until the end of the big winning game. If not, the value of the hit hold counter is returned to “0”. On the other hand, when a new hit hold has occurred, the number of hit holds newly generated is set in the hit hold counter. When “1” is subtracted from the hit hold counter as described above (S432), the special electric accessory game process shown in FIGS. 21 and 22 is terminated, and the process returns to the game control process of FIG.

  The process of opening the big winning opening 31d and executing the jackpot game is realized by the CPU 201 mounted on the main control board 200 executing the special electric accessory game process of FIGS. . Therefore, the CPU 201 mounted on the main control board 200 of this embodiment corresponds to the “big hit game execution means” in the present invention.

  Lastly, a process (S120) for setting the normal symbol variation time before starting the normal symbol game process (S150) in the game control process of FIG. 10 will be described.

D. Normal symbol variation time setting process:
FIG. 23 is a flowchart showing a normal symbol variation time setting process performed in the game control process of this embodiment. In the pachinko machine 1 of the present embodiment, the normal symbol variation time is appropriately set in the normal symbol variation time setting process, so that it is possible to avoid annoying the player after the end of the big hit game. It is possible.

  As shown in FIG. 23, when the normal symbol variation time setting process is started, it is first determined whether or not the time reduction flag is set to ON (S122). As described above, the hourly flag is a flag that is set to ON when the big hit game ends (see S428 in FIG. 22). When the hourly flag is set to ON, the first special symbol and the second special symbol are set. The fluctuation time is set to a fluctuation time shorter than usual. Corresponding to this, when the hourly flag is set to ON for the fluctuation time of the normal symbol (S122: yes), the fluctuation time is shorter than normal (0.8 seconds in this embodiment). Set (S124).

  On the other hand, when the time reduction flag is set to OFF (S122: no), it is determined whether or not the hit hold counter is “0” (S126). As described above, the hit hold counter is incremented by “1” every time a hit hold occurs (see S264 in FIG. 11 and S278 in FIG. 12), and is decremented by “1” every time the big hit game ends. It is a counter (see S432 in FIG. 22). Therefore, during the big hit game, the hit hold counter has a value of “1” or more. If the winning hold counter is “0” (S126: yes), the normal symbol change time is set to the normal change time (30 seconds in this embodiment) (S128). On the other hand, if the winning hold counter is not "0" (S126: no), the fluctuation time of the state where the fluctuation time of the normal symbol is shortened (2 seconds in this embodiment) is set (S130). As described above, when the normal symbol variation time is set in accordance with the setting of the time reduction flag and the value of the hit hold counter, the normal symbol variation time setting process shown in FIG. 23 is terminated, and the game control process of FIG. Return to. Then, after the above-described normal symbol game process (S150) is started and the normal symbol LED 29a blinks on the first symbol display device 28, it is stopped and displayed as a winning symbol or a miss symbol.

  It should be noted that the processing for setting the shortened state time to the normal symbol variation time from the occurrence of the hit-holding to the end of the big-hit game is performed by the CPU 201 mounted on the main control board 200 of this embodiment as shown in FIG. This is realized by executing the normal symbol variation time setting process shown in FIG. Therefore, the CPU 201 of the main control board 200 according to the present embodiment corresponds to the “common figure fluctuation shortening means” in the present invention.

  In the pachinko machine 1 according to the present embodiment, since the normal symbol variation time setting process as described above is performed, it is possible to avoid a situation in which the second start port 17b does not open after the big hit game ends. Yes. Hereinafter, this point will be described in detail.

  FIG. 24 is an explanatory diagram showing how the setting contents of the hourly flag and the normal symbol variation time are switched while the jackpot game is started during the hourly game, and the hourly game is started again after the jackpot game is finished. It is. The short-time game is a game that is performed with the short-time flag set to ON and the opening time extension flag set to ON. In FIG. 24, the jackpot game period is indicated by hatching.

  During the short-time game, the short-time flag is set to ON. Corresponding to this, the fluctuation time of the normal symbol is also set to a short time of 0.8 seconds. However, when the big hit game is started, the time reduction flag, the probability variation flag, the opening time extension flag, etc. are all set to OFF (see S364, S366, and S368 in FIG. 14), as shown in FIG. During the big hit game, the hourly flag is turned off. Along with this, the variation time of the normal symbol is also set to a longer time than during the short-time game. Therefore, if the normal symbol fluctuation display starts just before the end of the big hit game, the normal symbol will continue to show long time fluctuation display, even if the big hit game ends during that time and the short-time game starts again Even if it is done, it will be in the state which is not reflected in a normal symbol.

  On the other hand, in the pachinko machine 1 according to the present embodiment, when a hit hold occurs prior to the start of the big hit game, 1 is added to the hit hold counter. As a result, even if the big hit game is started and the hourly flag is turned OFF, the fluctuation time of the normal symbol is set not to the normal fluctuation time (30 seconds) but to the reduced fluctuation time (2 seconds). (S130 in FIG. 23). For this reason, even if the change display of the normal symbol is started just before the end of the jackpot game, the normal symbol is immediately stopped and displayed, and after that, the normal symbol is reflected reflecting the start of the short-time game. The variation time is reduced to 0.8 seconds. Further, when the normal symbol is hit and displayed as a stop symbol, the opening time of the second start port 17b is also extended from 0.5 seconds to 5 seconds. As a result, after the big hit game is over, the game can be continued in a state where the game ball can easily enter the second start port 17b.

  In addition, a thick dashed arrow shown in FIG. 24 represents a state in which the normal symbol is variably displayed when the variation time of the normal symbol is not set as the variation time of the shortened state. As shown in the figure, when the fluctuation display of the normal symbol is started just before the end of the big hit game, if the fluctuation time is not shortened, the normal fluctuation time of 30 seconds is set. Therefore, even if the big hit game ends, the short-time game is not reflected for a maximum of 30 seconds. On the other hand, in the pachinko machine 1 of the present embodiment, even when the time reduction flag is set to OFF, as long as the value of the hit hold counter is not 0, the fluctuation time of the normal symbol is reduced to the reduced time. Is set. For this reason, even if the normal symbol variation display is started just before the end of the big hit game, it is immediately stopped and the time-short game can be immediately reflected.

  Further, in the pachinko machine 1 of the present embodiment, when the hourly flag is OFF, since the variation time of the normal symbol is set to the variation time from the stage where the hitting suspension occurs, the big hit game is started. It is also possible to obtain an effect of making the player feel that this is the case and attracting the player to the game. This point will be described below.

  FIG. 25 is an explanatory diagram showing how the setting contents of the hourly flag and the normal symbol variation time are switched while the big hit game is started during the normal game and the hourly game is started again after the big hit game is finished. It is. The normal game is a game that is performed in a state where both the time-shortening flag and the opening time extension flag are set to OFF.

  During the normal game, the hourly flag is set to OFF, and the normal symbol variation time (30 seconds) is also set for the regular symbol variation time (S128 in FIG. 23). However, when a hit hold occurs, 1 is added to the hit hold counter, so the change time (2 seconds) in a state where the change time of the normal symbol is shortened is set (S130 in FIG. 23). In other words, when a winning hold occurs, the fluctuation time of the normal symbol, which was 30 seconds until then, is suddenly shortened to 2 seconds. Along with this, the frequency at which the second start port 17b is opened increases, and the player senses such a change and expects that the occurrence of the big hit game is near. As a result, the player can be attracted to the game.

  In the normal symbol variation time setting process shown in FIG. 23, if the hour / short flag is set to ON (S122: yes in FIG. 23), the short variation for the hour / short game regardless of the value of the hit hold counter. The time (0.8 seconds) is assumed to be set, and only when the time reduction flag is set to OFF (S122: no), the value of the hit hold counter is reflected in the normal symbol fluctuation time. . However, not limited to this, even when the time reduction flag is set to ON, if the value of the hit hold counter is not 0, the fluctuation time of the normal symbol is shortened to the fluctuation time (2 seconds). It may be set. In this way, when a hit occurs during a short-time game, the normal symbol variation time extends from 0.8 seconds to 2 seconds, so the opening frequency of the second start port 17b changes, and this is determined by the player. Can recognize that the occurrence of a big hit game is near.

  Further, the pachinko machine 1 of the present embodiment is provided with a first start port 17a and a second start port 17b. When a game ball enters the first start port 17a, the first symbol display When the device 28 displays the variation of the first special symbol and the game ball enters the second start port 17b, the second symbol display device 32 displays the variation of the second special symbol. In such a pachinko machine 1 of this embodiment, once a big hit is generated, the player can proceed with the game advantageously thereafter. That is, when the big hit game is over, the time-short flag is set to ON (S428 in FIG. 22), and the opening extension flag is also set to ON (S430 in FIG. 22), so the second start port 17b is frequently used. It will be open for a long time. In addition, as described above with reference to FIG. 5, in the state where the second start port 17b is opened, the second start port 17b is easier to enter the game ball than the first start port 17a. Enters the second starting port 17b. In addition, as described above with reference to FIG. 13, the second hold by entering the second start port 17b is digested in preference to the first hold by entering the first start port 17a. After all, after the big hit game, the game proceeds by exclusively displaying the second special symbol in a variable manner. Further, as described above with reference to FIG. 18, in the variable display by the second special symbol, since the 2R probability variation does not occur, when the winning symbol is stopped and the big hit game is started, the player You can always get a lot of game balls. Thus, once the big hit game is started, the game proceeds in a state advantageous to the player using the second special symbol exclusively.

  However, since the normal symbol variation display is started just before the end of the big hit game, if the normal symbol variation display continues even after the big hit game ends, the second start port 17b does not become open, so the game A ball cannot be entered. And when such a state continues and all the 2nd reservations are digested, this time, the 1st reservation by the entrance to the 1st starting opening 17a is digested, and the 1st special symbol is changed and displayed. Become. As described above with reference to FIG. 20, in the fluctuation display of the first special symbol, 2R probability variation hit occurs with a certain probability. The game ends. This situation is very disappointing for players who have finally generated a jackpot game and have been playing favorably since then. To avoid this situation, the second hold is While remaining, the game ball must enter the second start port 17b. However, even if the big hit game has already ended, if the second start port 17b does not readily open, the player feels impatient and frustrated.

  However, as described above, in the pachinko machine 1 according to the present embodiment, when a hit is held, even if the big hit game is started and the hourly flag is set to OFF, the time in which the fluctuation time of the normal symbol is shortened Set to For this reason, even if the normal symbol variation display is started just before the end of the big hit game, the normal symbol is immediately stopped and displayed, so that the second start port 17b can be opened immediately after the big hit game ends. it can. As a result, even in such a case, the game can be continued without annoying the player. Also, if a special symbol hit hold occurs during a normal game, the variation time of the normal symbol is shortened. This suggests that a player who notices this has a special symbol hold. As a result, it is possible to realize an unprecedented novel notice that a big hit notice is made using the fluctuation time of a normal symbol.

  The embodiments of the present invention have been described above. However, the present invention is not limited to these embodiments, and the present invention is not limited to the wording of each claim without departing from the scope described in each claim. Can be easily replaced by these, and improvements based on knowledge that a person skilled in the art normally has can be added as appropriate.

  For example, the pachinko machine 1 of the present embodiment has been described as a pachinko machine 1 with a normal symbol hit probability being constant, but for a pachinko machine 1 whose normal symbol hit probability varies with high probability, The present invention can be preferably applied. In such a pachinko machine 1, the normal symbol is likely to change with a high probability (for example, the hit probability: 86/89) at the same time as the change time of the special symbol is being reduced (during time reduction and during probability change). In other cases, that is, during normal games or during big hits, the probability is low (for example, hit probability: 2/89). The variation time of the normal symbol is shortened to 0.8 seconds while the variation time of the special symbol is shortened. On the other hand, the fluctuation time of the normal symbol during the normal game or the big hit is distributed to either 6 seconds or 0.8 seconds depending on the number of normal symbols held. For example, if there are 3 or more ordinary symbols on hold, it is 0.8 seconds, and if it is 2 or less, it is 6 seconds. Further, the opening time of the second starting port when the normal symbol is won is 0.1 seconds during normal game and big hit, and is 5 seconds while the variation time of the special symbol is shortened.

  When the present invention is applied to the pachinko machine 1 equipped with such a normal symbol probability changing function, when a special symbol is put on hold, the normal symbol variation time is 6 seconds (or 0.8 seconds) to 2 seconds. Changed to In the pachinko machine 1 of the above-described embodiment (ordinary symbol probability is constant), during the big hit, the opening frequency of the second starting port is short, but the opening frequency is increased. For this reason, the game ball is easily picked up at the second starting port, and the game ball is less likely to enter the big winning port, which hinders a smooth big hit game. However, in the pachinko machine 1 equipped with the normal symbol probability changing function, during the big hit, the probability of hitting the normal symbol is low, so the second start port is hardly opened. Therefore, it is less likely that a game ball is picked up at the second start opening, and it is easy to enter the big winning opening. As described above, when the present invention is applied to the pachinko machine 1 equipped with the normal symbol probability changing function, an advantage that the big hit game can be smoothly executed can be obtained.
