Description

  The present invention relates to a gaming machine, and more particularly, to a gaming machine (a ball game machine) such as a pachinko gaming machine such as a so-called seven machine, feathers, or a right-handed machine, or a combination type gaming machine (arranged ball gaming machine).

In a pachinko machine, the number of game balls that enter the starting port is stored as the number of holds, and if the number of holds is 1 or more, a determination of success or failure is made, and at the same time, a special symbol is displayed in a variable manner to reduce the number of holds ( Digestion). When the determination result is a big hit, the special symbol is stopped and displayed with the big hit symbol to generate a big hit state. In such a pachinko gaming machine, a gaming machine provided with two types of special symbols has been proposed (see Patent Document 1). In this gaming machine, when there is a hold of the second special symbol, the second special symbol is variably displayed with priority over the first special symbol, regardless of the number of hold of the first special symbol. Yes.
JP 2007-268126 A

  However, in the gaming machine adopting the priority variation of the second special symbol as in the above-mentioned Patent Document 1, even if a big hit occurs in the retention of the first special symbol having a low priority, the second special symbol is not retained. As long as it exists, there is a problem that the big hit due to the suspension of the first special symbol does not occur. Further, for example, when the hold of the first special symbol is a probable big hit that activates the probability variation function, and the hold of the second special symbol is a normal big hit, the normal big win is preferentially generated, which is disadvantageous for the player. Become. These things cause a decrease in the interest of the player.

  In view of the above, an object of the present invention is to improve the gaming interest in a gaming machine that preferentially changes one of two symbols.

  In order to achieve the above object, the gaming machine according to the present invention obtains and stores first hit / failure determination information based on a game ball entering a first starting port provided on the game board. Means, second hold storage means for acquiring and storing second determination information based on a game ball entering a second start port provided on the game board, and the first hold storage means When 1 hit determination information is stored, the first symbol display unit starts to display the variation of the first symbol with the execution of the first winning determination using the first hit determination information, and the variation The first symbol is stopped and displayed until a predetermined symbol stop display time elapses after the display ends, and when the result of the first winning / failing determination is a big hit, the first symbol is stopped and displayed with a predetermined big hit symbol. The first symbol display control means and the second reserved storage means When the failure determination information is stored, the second symbol display unit starts the variable display of the second symbol with the execution of the second determination of the correctness using the second failure determination information, and the variation display The second symbol is stopped and displayed until a predetermined symbol stop display time elapses after the end, and when the result of the second determination is a big hit, the second symbol is stopped and displayed with a predetermined big hit symbol. When the first winning / failing determination information is stored by the two symbol display control means and the first holding storage means, and the second winning / failing determination information is stored by the second holding storage means, The second symbol priority variation means for performing the second symbol priority variation to display the variation of the second symbol in preference to the variation display of the first symbol, and the first symbol or the second symbol stops at the jackpot symbol If displayed, to the player A jackpot game executing means for executing a profitable jackpot game, a pitching frequency improving means for improving a game ball pitching frequency with respect to the second starting port, and the first holding storage means prior to the execution of the first hit / fail judgment A first symbol pre-determination means for performing a first symbol pre-determination for determining whether or not the first winning / failing determination information stored in is a jackpot information for deriving the jackpot as a result of the first winning / failing determination; When the frequency of entering the game ball into the second starting port is improved by the pitching frequency improving means, the first symbol prior determination means determines that the first winning / failing determination information is the jackpot information. The symbol stop display time at the time of the variation display of the first symbol and the second symbol executed before the variation display of the first symbol accompanied by the execution of the first winning / failing determination using the jackpot information The large It is characterized by comprising symbol stop display time setting means for setting according to the type of jackpot derived from the hit information.

  As described above, when it is determined in the first symbol prior determination that the first special symbol success / failure determination information is jackpot information, the symbol stop display time is set in accordance with the type of jackpot information (probability jackpot or normal jackpot). By doing so, it is possible to change the occurrence time of the jackpot due to the variation display of the first symbol that is the subject of the first symbol prior determination. As a result, a gaming machine having a novel gaming characteristic which has not been conventionally available can be provided, and the gaming interest can be improved.

According to the present invention, there is provided a probability changing means for improving a probability that a result of the first winning / failing determination and the second winning / failing determination is a big hit after the jackpot game is ended,
The symbol stop display time setting means is determined when the first symbol prior determination means determines that the first success / failure determination information is probability variation jackpot information for deriving a jackpot that triggers the start of operation of the probability varying means. Is the symbol stop display time at the time of the variation display of the first symbol and the second symbol executed before the variation display of the first symbol accompanied by the execution of the first winning / failing determination using the probability variation jackpot information. If the first symbol pre-determination means determines that the first winning / failing determination information is normal jackpot information for deriving a jackpot that does not trigger the operation of the probability variation means, the normal jackpot information The symbol stop display time at the time of the variation display of the first symbol and the second symbol executed before the variation display of the first symbol accompanied by the execution of the first success / failure determination using the It is characterized in that.

  As a result, when the first success / failure determination information derives a jackpot that triggers the start of the operation of the probability changing means, the reduction rate of the number of retained symbols in the second symbol is accelerated by shortening the symbol stop display time. Thus, it is possible to accelerate the occurrence of the big hit due to the variation display of the first symbol which is the object of the prior determination, and as a result, it is possible to promptly generate the probable big hit that is advantageous to the player. Further, when the first success / failure determination information derives a jackpot that does not trigger the start of the operation of the probability changing means, the rate of decrease in the number of retained symbols in the second symbol is slowed by extending the symbol stop display time. Therefore, it is possible to delay the occurrence of the big hit due to the variation display of the first symbol that has been subject to the prior determination, and as a result, it is possible to delay the occurrence of the normal big hit that is disadvantageous to the player. As a result, it is possible to increase the number of retained symbols of the second symbol by increasing the chance of entering the second starting port (so as not to become zero), and a probable big hit caused by the retention of the second symbol occurs. Opportunities can be increased. Furthermore, if the current gaming state is a probability change game, the rate of decrease in the number of symbols in the second symbol will be slowed down by extending the symbol stop display time, and the symbol in the first symbol subject to the first symbol prior judgment will be held. By delaying the occurrence of the normal jackpot due to the game, it is possible to extend the probability change game time advantageous to the player.

Further, according to the present invention, in the big hit game executed by the big hit game execution means, the game ball is inserted after the variable ball opening provided on the game board is in an open state in which the game ball can easily enter. The first big hit game in which a round until the ball is difficult to be closed is performed a plurality of times, and the opening time of the variable entrance is shorter than the first big hit game, and the number of rounds is the first big hit game With less second big hit games,
When the symbol stop display time setting means determines that the first symbol prior determination means determines that the first winning / failing determination information is first jackpot information for deriving a jackpot that triggers the start of the first jackpot game. The symbol stop display at the time of the variable display of the first symbol and the second symbol executed before the variable display of the first symbol accompanied by the execution of the first winning / failing determination using the first jackpot information When the time is shortened and the first symbol pre-determining means determines that the first success / failure determination information is the second jackpot information for deriving the jackpot that triggers the start of the second jackpot game, The symbol stop display time at the time of the variable display of the first symbol and the second symbol, which is executed prior to the variable display of the first symbol accompanying the execution of the first winning / failing determination using the second jackpot information, is extended. That It is a symptom.

  As a result, when the determination result of the first symbol pre-determination is to start the first big hit game advantageous to the player, the decrease rate of the number of holdings of the second symbol is accelerated by shortening the symbol stop display time. As a result, it is possible to generate a state in which the second symbol hold is zero, and as a result, it is possible to accelerate the start of the first big hit game due to the variation display of the first symbol that is the target of the prior determination. In addition, if the determination result of the first symbol prior determination is to start the second big hit game that is disadvantageous to the player, the rate of decrease in the number of retained symbols in the second symbol is slowed down by extending the symbol stop display time. It is possible to increase the number of retained symbols of the second symbol by increasing the chance to enter the second starting port (so as not to become zero), and as a result, the variation of the first symbol subject to prior determination The start of the second big hit game resulting from the display can be delayed.

  Further, according to the present invention, when the entrance frequency improving unit determines that the first winning / failing determination information is the normal jackpot information or the second jackpot information by the first symbol prior determination unit, Extending the symbol stop display time at the time of the variable display of the first symbol and the second symbol on the condition that the number of suspension of the second success / failure determination information by the second reservation storage means is less than a predetermined number It is characterized by.

  As a result, when the chance to enter the second starting port is increased by extending the symbol stop display time, if there is already a large number of second special symbol reserves, it becomes too advantageous to the player (excessive prizes). Giving a ball etc.).

  The normal symbol display part 51 is comprised from one LED, and a normal symbol is displayed by this LED. In the normal symbol display unit 51, the normal symbol variation display and stop display are performed. In the normal symbol display unit 51, the normal symbol starts to change when the game ball passes through the normal symbol operating gate 27, and after a predetermined time has passed, the normal symbol hits and stops display in the normal symbol display mode or the dismissed normal symbol display mode. Is done. Then, when the normal symbol is stopped and displayed in the preset normal symbol display mode, the second start port 28b is opened for a predetermined time (for example, 0.1 second).

  In the present embodiment, a random number for determining whether or not a normal symbol is provided is prepared. This random number for determining whether or not a normal symbol is used determines whether or not the second starting port 28b is activated when the game ball passes through the normal symbol operating gate 27. This is used to determine whether or not a normal symbol is appropriate. The normal symbol success / failure random number is set in advance with a hit value, and the normal symbol success / failure determination random number acquired at the timing when the game ball passes the normal symbol operation gate 27 matches the win value. Determined. When it is determined to be a winning, the normal symbol that is stopped and displayed on the normal symbol display unit 51 is determined as the display mode of the winning normal symbol. On the other hand, when it is determined to be out (when the acquired normal symbol success / failure random number does not match the winning value), the normal symbol stopped and displayed in the normal symbol display unit 51 is determined as the display mode of the out of normal symbol. Is done. Note that the normal symbol success / failure determination and the normal symbol stop symbol determination are performed by a CPU 200a of the main control board 200 described later.

  Here, normal symbol holding will be described. The normal symbol hold display section 52 displays the normal symbol hold number, and the number of game balls that have passed through the normal symbol operation gate 27 can be held up to the maximum hold number (four in this embodiment). Each time the next normal symbol win / fail determination is made and the normal symbol variation display is started, the number of unstarted times (the number of reservations) is consumed, and the number of normal symbol reservations is decreased by one. The general-purpose hold display unit 52 includes two LEDs, and can display the number of holds with an upper limit of four by combining turning off, lighting, and blinking of the two LEDs. The normal symbol holding and holding digest are performed by a CPU 200a of the main control board 200 described later. Along with the holding of the normal symbol, the random number for determining whether or not the normal symbol is stored is stored in a predetermined area of the RAM of the main control board 200.

  Next, the special symbol will be described. The first special symbol display unit 61 and the second special symbol display unit 62 are each composed of seven LEDs, and the first special symbol and the second special symbol are displayed by these LEDs. Each of the LEDs constituting these special symbol display units 61 and 62 can be turned on and off, and a plurality of special symbol display modes can be displayed by a combination of turning on and off of these LEDs. Of the combinations of special symbols displayed by the seven LEDs, a specific combination is set as a hit special symbol (big hit symbol), and a portion other than the hit special symbol is set off as a special symbol (off symbol). ing. In this embodiment, the special symbol variation display is performed by blinking display in which each LED is repeatedly turned on and off. In this embodiment, a plurality of jackpot symbols are set, and specifically, “probable variation jackpot symbol” and “normal jackpot symbol” are set as described later.

  In the first special symbol display unit 61, when the game ball enters the first starting port 28a, the first special symbol starts to fluctuate, and after the predetermined time has elapsed, the first special symbol is stopped and displayed as a big hit symbol or a missed symbol. The In the second special symbol display unit 62, when the game ball enters the second start port 28b, the second special symbol starts to change, and after the predetermined time has elapsed, the second special symbol is stopped and displayed as a big hit symbol or a missed symbol. The The stop display of the first special symbol and the second special symbol is performed until a predetermined stop display time has elapsed after the end of the variable display, and the next variable display can be started after the stop display time has elapsed. In this embodiment, three different types of stop display times, “normal stop display time”, “stop display time A”, and “stop display time B”, are provided as the stop display time, depending on the situation. One stop display time can be set. Details of this will be described later.

  In addition, the first special symbol of the first special symbol display unit 61 and the second special symbol of the second special symbol display unit 62 are configured not to be variably displayed at the same time. That is, when a game ball enters one of the start openings 28a and 28b and the special symbol is variably displayed on one of the special symbol display portions 61 and 62 corresponding to the entrance, the other start is started. When a game ball enters the mouth, the special symbol change in the other special symbol display unit is suspended. The first special symbol corresponds to the first symbol of the present invention, the first special symbol display unit 61 corresponds to the first symbol display unit of the present invention, and the second special symbol corresponds to the second symbol of the present invention. The second special symbol display unit 62 corresponds to the second symbol display unit of the present invention.

  In the present embodiment, the first special symbol success / failure determination, which is acquired when a game ball enters the first start port 28a and is used for determining whether or not to execute the big hit game (special game), is performed. Random numbers for use and second special symbol success / failure determination, which is acquired when a game ball enters the second start port 28b and is used to determine whether or not to execute a big hit game (special game). A random number is provided. Furthermore, a first special symbol determining random number for determining the stop symbol of the first special symbol and a second special symbol determining random number for determining the stop symbol of the second special symbol are provided.

  The first special symbol success / failure determination random number and the first special symbol determination random number are acquired along with the game ball entering the first start port 28a, and the first special symbol success / failure determination random number and the first special symbol determination random number are obtained. The symbol determining random number is stored in a predetermined area (first reserved storage area) of the RAM of the main control board 200. Along with the game ball entering the second start port 28b, a second special symbol success / failure determination random number and a second special symbol determination random number are acquired, and a predetermined area (second reserved memory) of the RAM of the main control board 200 is acquired. Area). The first special symbol success / failure random number and the first special symbol determination random number correspond to the first special symbol determination / determination information of the present invention, and the second special symbol success / failure determination random number and the second special symbol determination random number are the present invention. This corresponds to the second determination information.

  Here, the holding of special symbols will be described. The first special symbol hold display unit 53 and the second special symbol hold display unit 54 are each composed of two LEDs, and the number of holds can be set up to 4 each by combining the turn-off, lighting, and blinking of the two LEDs. Can be displayed.

  The number of game balls that have entered the first start port 28a can be held until reaching the maximum number of reservations (four in this embodiment) as the number of first special symbol reservations. The first special symbol hold number is acquired every time a game ball enters the first start port 28a and is stored in a predetermined area (first hold storage area) of the RAM of the main control board 200. This corresponds to the number of random numbers for special symbol determination (memory number). In the present embodiment, the first special symbol determination random number is acquired together with the first special symbol success / failure random number as the game ball enters the first starting port 28a, so the first special symbol hold number is This also corresponds to the number of stored random numbers for determining the first special symbol. The first special symbol hold count is digested and decreased by one each time the first special symbol determination is made and the first special symbol variation display is started.

  The number of game balls that have entered the second start port 28b can be held until reaching the maximum number of reservations (four in this embodiment) as the number of second special symbol reservations. The second special symbol hold number is acquired every time a game ball enters the second start port 28b and is stored in a predetermined area (second hold storage area) of the RAM of the main control board 200. This corresponds to the number of random numbers for special symbol determination (memory number). In the present embodiment, the second special symbol determination random number is also acquired together with the second special symbol success / failure random number as the game ball enters the second starting port 28b. This also corresponds to the number of stored random numbers for determining the second special symbol. The second special symbol hold count is digested each time the second special symbol success / failure determination is performed and the variation display of the second special symbol is started, and decreases by one.

  The first and second special symbols are reserved and reserved by a CPU 200a of the main control board 200, which will be described later. The CPU 200a of the main control board 200 and the RAM of the main control board 200 are the first of the present invention. This corresponds to the first hold storage means and the second hold storage means.

  A special symbol success / failure determination random number is set with a winning / failure determination hit value, and a special symbol success / failure determination random number acquired at the timing when the game ball enters the first start port 28a or the second start port 28b. Is determined to be a big hit if it matches the hit value. In this embodiment, the random number for determination of success / failure is 600 pieces of 1 to 599, and the winning value for determination of success / failure is two pieces of “1, 3”, and the winning probability at the normal game is 1/300. The first special symbol success / failure determination is performed when the first special symbol starts variable display, and the second special symbol correctness determination is performed when the second special symbol starts variable display. When the result of the first special symbol success / failure determination is a big hit, the first special symbol that is stopped and displayed on the first special symbol display unit 61 is determined as a big hit symbol (probability big hit symbol or normal big hit symbol). When the result of the 2 special symbol success / failure determination is a big hit, the second special symbol stopped and displayed on the second special symbol display unit 62 is determined as a big hit symbol (probability big hit symbol or normal big hit symbol). The type of jackpot symbol of the first special symbol is determined based on the first special symbol determining random number, and the type of jackpot symbol of the second special symbol is determined based on the second special symbol determining random number.

  On the other hand, when the first special symbol success / failure determination is out, the first special symbol stopped and displayed on the first special symbol display unit 61 is determined to be out of symbol, and when the second special symbol success / failure determination is out The second special symbol that is stopped and displayed by the second special symbol display unit 62 is determined to be a detached symbol.

  The first special symbol and the second special symbol are configured to be variably displayed according to a predetermined variation pattern. This variation pattern defines the variation time of the special symbol and the presence / absence of the reach effect in the variation (effect content). The variation pattern of the first special symbol and the second special symbol is a variation pattern table (variation pattern storage means) in which a plurality of variation patterns are stored when the first special symbol success / failure determination and the second special symbol success / failure determination are executed. ) Is selected by lottery.

  A plurality of variation patterns tables of the first special symbol and the second special symbol are prepared, and are selected and used according to the gaming state. The plurality of variation pattern tables include a hit variation pattern table selected when the success / failure determination result is a big hit, and a miss variation pattern table selected when the success / failure determination result is unacceptable.

  In the gaming machine 1 according to the present embodiment, when a game ball enters the first start port 28a and the suspension occurs, in other words, the first ball that is acquired as the game ball enters the first start port 28a. When the special symbol success / failure determination random number and the first special symbol determination random number are stored in a predetermined area (first reserved storage area) of the RAM of the main control board 200, the special symbol success / failure determination is reserved prior to the first special symbol determination determination. A pre-determination process is performed to determine whether or not the first special symbol success / failure determination random number coincides with the success / failure determination hit value when the hold occurs. Then, if it is determined in the pre-determination process that the first special symbol success / failure determination random number matches the success / failure determination hit value, the first special symbol hold / permission flag is set to ON. The first special symbol holding hit flag is a flag indicating that “winning” exists in the holding. In the first special symbol hold per flag of the present embodiment, a first special symbol hold normal hit flag that is set to ON when the first special symbol success / failure determination random number matches a hit value that generates a normal big hit. And a first special symbol hold probability variation flag that is set to ON when the first special symbol success / failure random number coincides with a hit value that generates a probability variation big hit.

  In addition, the gaming machine 1 according to the present embodiment is configured such that the second special symbol priority variation process is performed in which the variation display of the second special symbol is executed with priority over the first special symbol. That is, when both the number of the first special symbol hold and the number of the second special symbol hold are 1 or more, the second special symbol starts to fluctuate preferentially from the first special symbol, and the hold of the second special symbol is stopped. Digested preferentially. Then, when the first special symbol hold count is 1 or more and the second special symbol hold count becomes zero, the variable display of the first special symbol is executed.

  Further, the special symbol success / failure determination, the determination of the variation pattern of the special symbol, the determination of the special symbol stop symbol, the preliminary determination process, and the priority variation of the second special symbol are configured to be performed by a CPU 200a of the main control board 200 described later. Has been. The CPU 200a of the main control board 200 corresponds to the first symbol display control means, the second symbol display control means, the first symbol prior determination means, and the second symbol priority change means of the present invention.

  Next, the jackpot game (special game) will be described. When the first special symbol stopped and displayed on the first special symbol display unit 61 is a hit special symbol (when the result of the first special symbol determination is a big hit), or stopped on the second special symbol display unit 62 When the displayed second special symbol is a hit special symbol (when the result of the second special symbol success / failure determination is a big hit), the CPU 200a of the main control board 200 makes a big hit game (relatively advantageous to the player) Special game) is started. The jackpot game is started by setting the jackpot game flag to ON. The big hit game is to give a player a profit (prize ball) with respect to entering the game ball into the big prize opening 33a by operating the big prize device 33, in other words, by opening and closing the big prize opening 33a a plurality of times. The CPU 200a of the main control board 200 corresponds to the big hit game execution means of the present invention. The big hit game is realized by repeatedly executing a special electric accessory game process described later.

  During the big hit game (during special game), the big prize device 33 is operated, and a predetermined number of prize balls (for example, 15 for one pitch) according to the number of game balls entered into the big prize opening 33a. Award balls). Specifically, at the start of the big hit game, the big prize opening device (special electric accessory) 33 is continuously operated, and the big prize opening opening / closing operation for switching the big prize opening 33a between the open state and the closed state is continuously performed a plurality of times. Done. With the start of the operation of the special winning device 33, the special winning opening 33a is opened. This open state is ended when a predetermined end condition is established, and the open special winning opening 33a is closed. As a predetermined end condition, when the opening time of the big winning opening 33a reaches a predetermined time (30 seconds in the present embodiment), or when the number of game balls entered into the opened large winning opening 33a is a predetermined number (this execution) In the example, it is possible to reach 10).

  When it is assumed that one round is from the start to the end of the open state of the big winning opening 33a, the big hit game is ended by performing a predetermined number of rounds. In the grand prize winning device 33, after the opening of the big prize winning opening 33a is completed, that is, after a predetermined time (for example, 2 seconds) has passed since the big winning prize opening 33a is closed, the big winning prize opening 33a is again opened. Round begins. The opening / closing operation of the grand prize winning port 33a in which one round is from the start to the end of the big winning port 33a is repeated until a predetermined maximum number of continuous rounds (15 rounds in this embodiment) is completed.

  In the gaming machine of this embodiment, after the big hit game is finished, a specific game (so-called short-time game and probability variable game) in which the variable time shortening function, the open time extending function, and the probability varying function are activated is started. Special symbol success / failure determination (first special symbol success / failure determination and second special symbol success / failure determination) has multiple types of jackpots, and the special symbol success / failure determination result is a normal jackpot (the special symbol stop symbol is a normal jackpot) In the case of (symbol), the short-time game is started after the end of the big hit game, and when the result of the special symbol success / failure determination is a probable big hit (the stop symbol of the special symbol is the probable big hit symbol), the probable game Is started. Note that the variable time shortening function, the opening time extending function, and the probability varying function are activated by setting the fluctuation shortening flag, the opening extension flag, and the probability variation flag to ON, respectively.

  When the result of the special symbol success / failure determination is a normal jackpot (the special symbol stop symbol is a normal jackpot symbol), after the jackpot game is over, the variable time shortening function and the opening time extension for extending the opening time of the second start port 28b are extended. The function is activated and the short-time game is started. The variation time shortening function and the opening time extension function are activated or stopped by the control of the CPU 200a of the main control board 200. The variation time shortening function includes a normal symbol variation time shortening function for shortening the ordinary symbol variation time. And a special symbol variation time shortening function for shortening the special symbol variation time. The fluctuation time shortening function and the opening time extension function operate after the big hit game is finished until the next big hit game is started, or until the number of fluctuations of the special symbol reaches a predetermined number (100 times in this example). . By the operation of the opening time extension function, the frequency of entering the game ball into the second start port 28b becomes higher than normal (when the opening extension function is not operated). By the operation of the opening time extension function, the opening time of the second start port 28b is extended to 9 seconds (3 seconds × 3 times opening), for example, from 0.1 seconds at the normal time. As a result, the frequency of entering the game ball into the second start port 28b becomes higher than normal (when the opening extension function is not activated). This opening time extension function (CPU 200a of main control board 200) corresponds to the pitching frequency improving means of the present invention.

  If the result of the special symbol success / failure determination is a probable big hit (the stop symbol of the special symbol is a probable big hit symbol), after the big hit game ends, the probability variation function starts to operate, and the probable variable game is started. The probability variation game is realized by the control of the CPU 200a of the main control board 200. In this probability variation game, in addition to the variable time shortening function and the open time extension function, the probability of the special symbol success / failure determination, that is, the special symbol is a big hit. The probability variation function that changes (improves) the probability of stopping display with symbols is activated. While the probability variation function is in operation, the winning value for the special symbol success / failure determination is improved by increasing the winning value for the success / failure determination. In this embodiment, the normal game hit value is “1, 3”, and the probability change game hit value is “1, 3, 5, 7, 9, 10,. The winning probability increases from 1/300 to 1/30. The probability variation function operates after the jackpot game is over until the next jackpot game is started. The CPU 200a of the main control board 200 corresponds to the probability changing means of the present invention.

  As described above, the special symbols (first special symbol and second special symbol) are stopped and displayed for a predetermined stop display time after the end of the variable display. In the present embodiment, when the above-described advance determination process is performed when the open time extension function is activated, different stop display times are set depending on the result of the advance determination process. Specifically, when it is determined in the pre-determination process that the random number for determining whether or not the first special symbol is the same as the winning value for generating a probable big hit, the normal stop display time ( When the stop display time A (for example, 1 second) is set to be shorter than (for example, 2 seconds), and it is determined in the pre-determination process that the first special symbol success / failure determination random number coincides with the hit value that normally generates a big hit. Is set to a stop display time B (for example, 3 seconds) longer than the normal stop display time. The special symbol stop display time is set by the CPU 200a of the main control board 200, and the CPU 200a of the main control board 200 corresponds to the stop display time setting means of the present invention. Further, the probability variation big hit corresponds to the first big hit of the present invention, the hit value for generating the probability variation big hit corresponds to the first big hit information of the present invention, the normal big hit corresponds to the second big hit of the present invention, and the normal big hit is determined. The hit value to be generated corresponds to the second big hit information of the present invention.

  Next, the effect symbols displayed on the effect display device 25 will be described. FIG. 3 shows a screen display example of the effect display device 25. As shown in FIG. 3, in the display area of the effect display device 25, effect symbol display units 25a to 25c for displaying effect symbols are provided. The effect symbols of the effect symbol display units 25a to 25c are displayed in conjunction with the change display and stop display of the first special symbol of the first special symbol display unit 61 or the second special symbol of the second special symbol display unit 62.

  The effect symbol display sections 25a to 25c are three symbol displays including a left symbol display region 25a in which a left symbol is displayed, a middle symbol display region 25b in which a middle symbol is displayed, and a right symbol display region 25c in which a right symbol is displayed. It consists of areas. Each of the symbol display areas 25a to 25c is set in a direction that is substantially orthogonal to the arrangement direction of these display areas, in this case, in the vertical direction (vertical direction). Each of the symbol display areas 25a to 25c can display symbols consisting of “1” to “9”.

  When the first special symbol or the second special symbol is stopped and displayed in any of the symbols, the first symbol or the second special symbol is started. The special symbol or the second special symbol is stopped and displayed with a symbol corresponding to the stop symbol. In the production design, a combination of even symbols with the same three digits corresponds to a normal big hit symbol with a special symbol, a combination of odd symbols with the same three digits corresponds to a probabilistic jackpot symbol with a special symbol, and other symbol combinations are special. Corresponds to symbols that are out of design.

  The design pattern variation mode (variation pattern) and stop symbol determination are configured to be performed by the CPU 260a of the sub-control board 260 based on a variation pattern designation command transmitted from the CPU 200a of the main control board 200. Here, the variation pattern designation command transmitted from the CPU 200a of the main control board 200 indicates the variation pattern of the special symbol. Specifically, the variation content of the special symbol, the contents of the representation such as the presence / absence of the reach effect, etc. Show. The CPU 200a of the main control board 200 determines the variation pattern of the special symbol at random (by random number lottery) according to the determination result of the special symbol. Then, based on the variation pattern of the special symbol determined by the CPU 200a of the main control board 200, the CPU 260a of the sub control board 260 determines the effect pattern of the effect symbol displayed on the effect symbol display unit 25a.

The first hold display unit 25d is displayed in conjunction with the first special symbol hold display unit 53, and the number of circular figures “◯” corresponding to the first special symbol hold number is displayed. The second hold display unit 25e is displayed in conjunction with the second special symbol hold display unit 54, and the number of circular figures “◯” corresponding to the second special symbol hold number is displayed. In the hold display sections 25d and 25e of the present embodiment, the leftmost circle figure “◯” indicates the hold stored first, and the hold newly stored in order toward the right side.

  As described above, in the gaming machine 1 of this embodiment, prior to the first special symbol success / failure determination, whether or not the first special symbol success / failure determination random number coincides with the success / failure determination success value (whether it is jackpot information). Pre-determination processing for determining whether or not) is performed. Then, as a result of the pre-determination process, if the first special symbol success / failure determination random number matches the success / failure determination hit value, the player can be informed of the possibility of a big hit using the display area of the effect display device 25. A hold notice effect is given.

  The hold notice effect is only required to be able to distinguish the hold display of the first special symbol success / failure determination random number that coincides with the hit determination hit value from other hold displays, for example, the first hold display section of the effect display device 25. In 25d, it can be performed by changing the circular figure “◯” corresponding to the holding of the first special symbol that is the subject of the holding notice to the star figure “☆” that is a different type of symbol. For example, when the number of first special symbol hold is the upper limit “4”, and the first special symbol held third is a win, the display on the first hold display portion 25d is “◯ ○ ☆ ○ ”. The hold notice is performed as an effect by the CPU 260a of the sub control board 260 based on the hold notice command transmitted from the CPU 200a of the main control board 200.

  Next, the operation of the gaming machine 1 of this embodiment will be described based on a flowchart. FIG. 5 shows an example of a main job executed by the CPU 200a of the main control board 200 based on a program stored in the ROM. The main job shown in FIG. 5 includes a game start process S200, a normal symbol game process S300, a normal electric game game process S400, a special symbol game process S500, and a special electric game game process S600 after executing the power-on process S100. Each step is repeatedly executed every time the timer is reset. In the power-off generation process S700, when a power-off occurs due to a power failure or the like, the used registers and stack pointers are saved, the payout motor is stopped, and so on, and when a system reset occurs, the process proceeds to the power-on process S100. It has become.

  The power-on process S100 is performed when the power is turned on and when the power is restored after the power is cut off. When the power is turned on, a RAM initialization process or the like is performed, and when the power is turned off, the game state is restored. The return setting is performed. In the game start process S200, detection of various switch states, update of various random numbers, prize ball control, and the like are performed.

  In the normal symbol game processing S300, first, whether or not the normal symbol is determined is determined, and the normal symbol display unit 51 (see FIG. 2) determines whether the normal symbol is to be stopped and displayed as a winning symbol or as a stop symbol. To do. Next, after setting the normal symbol fluctuation display time, the normal symbol fluctuation display is started. When the variable display time has elapsed, the normal symbol is stopped and displayed with the determined symbol, and when the normal symbol is stopped and displayed, the operation of the normal electric accessory is started (second start-up). The mouth 28b is opened). In the normal symbol game process, the normal symbol variation display and the stop display are performed as described above, and when the normal symbol is stopped and displayed as the winning symbol, the second start port 28b is activated. When the second start port 28b is actuated, the pair of blade pieces open to the left and right, and the second start port 28b is opened.

  In the ordinary electric accessory game process S400, it is determined whether or not the opening time for maintaining the second start port 28b in the open state has elapsed. If the open time has not elapsed, the second start port 28b is defined. It is determined whether or not a winning number has been won. When it is determined that the predetermined number of winnings has been won at the second starting port 28b in the open state, or when it is determined that the opening time of the second starting port 28b in the open state has elapsed, a pair of The blade piece 28c is closed, and the second start port 28b is closed (normal state).

  Next, the special symbol game process S500 will be described based on the flowcharts of FIGS. As shown in FIG. 6A, first, a start opening winning process is performed (S501). Here, the start opening winning process will be described based on the flowchart of FIG.

  First, it is determined whether or not the first start port 28a has been won (S550). If it is determined that the first start port 28a has not been won (S550: NO). The process proceeds to S556. On the other hand, if it is determined that the first start port 28a has been won (S550: YES), it is determined whether or not the first special symbol hold number is less than 4 (S551). As a result, when it is determined that the number of first special symbol hold is less than 4 (S551: YES), a first special symbol random number (first symbol success / failure determination information) is acquired and stored (S552). . The first special symbol random number includes a first special symbol determination random number, a first special symbol hit random number, a reach random number, and the like. Thereby, the 1st special symbol reservation number increases by one.

  Next, the first special symbol reservation number command is transmitted to the sub-control board 260 (S553). The first special symbol hold count command is a command for displaying the first special symbol hold count on the first hold display section 25d of the effect display device 25.

  Next, a first special symbol preliminary determination process is performed (S554). Here, the first special symbol prior determination process will be described based on the flowchart of FIG. First, it is determined whether or not the first special symbol success / failure determination random number stored in S552 matches the winning value (whether or not it is jackpot information) (S5540). In this embodiment, it is determined whether or not the first special symbol success / failure determination random number matches the normal game hit value “1, 3”. For this reason, in S5540, the hit value “5, 7, 9, 10,..., 100” increased for the probability-changing game even during the probability-changing game is not subject to prior determination. This is because the random number for determining whether or not the first special symbol is correct matches the winning value increased for the probability variation game, and when the probability variation game ends after the retention notice is made, This is to prevent the hold from being lost.

  As a result of the determination processing in S5520, if it is determined that the first special symbol success / failure determination random number does not match the winning value, that is, if the first special symbol is not on hold (S5540: NO), 1 The special symbol prior determination process is terminated. On the other hand, when it is determined that the first special symbol success / failure random number matches the winning value (S5540: YES), the first special symbol success / failure determination random number is stored in S552 (see FIG. 7) together with the first special symbol success / failure determination random number. It is determined whether or not the first special symbol success / failure determination random number coincides with a winning value that generates a probable big hit (S5541).

  As a result, if it is determined that the first special symbol success / failure random number coincides with the winning value for generating a probable big hit (S5541: YES), the first special symbol hold probable winning change flag is set to ON. (S5542). On the other hand, when it is determined that the first special symbol success / failure random number does not coincide with the winning value that generates the probable big hit, that is, it matches the winning value that generates the normal big hit (S5541: NO), The first special symbol reservation normal hit flag is set to ON (S5543).

  Next, returning to the start opening winning process of FIG. 7, the first special symbol prior determination result command is transmitted to the sub-control board 260 (S555). The first special symbol pre-determination result command indicates the result of the first special symbol pre-determination. If the first special symbol pre-decision determination random number matches the winning value, it is determined whether or not it is a big hit ( (If the first special symbol success / failure random number matches the winning value), the jackpot type information indicating the type of jackpot, the reach presence / absence information indicating whether or not the reach effect is performed, and the reach when the reach effect is performed It includes reach type information indicating the type of performance. Based on the content of the first special symbol advance determination result command, the CPU 260a of the sub-control board 260 determines that the first special symbol hold / display unit 25d when the first special symbol success / failure random number matches the winning value. A hold notice effect is displayed to display the corresponding hold display in a special manner.

  Next, it is determined whether or not the second starting port 28b has been won (S556). If it is determined that the second starting port 28b has not been won (S556: NO). The start opening winning process is terminated. On the other hand, when it is determined that the second start port 28b has been won (S556: YES), it is determined whether the second special symbol display number is less than 4 (S557). As a result, when it is determined that the number of second special symbol reservation is not less than 4 (S557: NO), the start opening winning process is terminated and it is determined that the number of second special symbol reservation is less than 4 (S557: YES), the second special symbol random number (second symbol success / failure determination information) is acquired and stored (S558). The second special symbol random number includes a second special symbol determination random number, a second special symbol determination random number, a reach random number, and the like. Thereby, the number of second special symbol reservation increases by one. Then, the second special symbol reservation number command is transmitted to the CPU 260a of the sub-control board 260 (S559). The second special symbol hold number command is a command for displaying the second special symbol hold number on the second hold display unit 25e of the effect display device 25.

  Returning to FIG. 6A, when returning from the start opening winning process (S501), it is determined whether or not a big hit game is being played (S502). As a result, if it is determined that the game is a big hit game (S502: YES), the special symbol game process is terminated. If it is determined that the game is not a big hit game (S502: NO), the first special symbol is processed. Alternatively, it is determined whether or not the second special symbol is changing (S503). As a result, when it is determined that either the first special symbol or the second special symbol is changing (S503: YES), the process proceeds to S510 described later, and the first special symbol or the second special symbol is performed. If it is determined that none of the symbols is changing (S503: NO), it is determined whether or not the first special symbol or the second special symbol is in the stop display time (S504). If it is determined that it is during the stop display time of the first special symbol or the second special symbol (S504: YES), the process proceeds to S513 described later, and the first special symbol or the second special symbol is stopped and displayed. When it is determined that it is not in time (S504: NO), it is determined whether or not the second special symbol reservation number is zero (S506). As a result, when it is determined that the number of second special symbol reservation is zero (S506: YES), it is determined whether or not the number of first special symbol reservation is zero (S507).

  And when it determines with the 1st special symbol holding | maintenance number being zero (S507: YES), a special symbol game process is complete | finished. On the other hand, when it is determined that the number of first special symbol hold is not zero (S507: NO), a first special symbol variation display process is performed (S508). Here, the first special symbol variation display process will be described based on the flowchart of FIG. First, a random number for determining whether or not the first special symbol is stored in a predetermined area (first reserved storage area) of the RAM of the main control board 200 (for determining whether or not the game ball has entered the first start port 28a) (Random number) is read (S5080), and the first special symbol determination is made (S5081). In the first special symbol success / failure determination, when the probability variation function is in operation (probability variation game), the probability of the probability variation when the probability variation, that is, the probability that the determination result is a big hit is increased and the stop display time setting process is performed. If it is determined that the probability variation function is not in operation (in normal game), the probability of success / failure during non-probability variation, that is, the probability that the determination result will be a big hit is reduced. Judgment is made in the state (low probability state).

  Next, a variation pattern setting process for the first special symbol is performed (S5082). In the first special symbol variation pattern setting process, if the success / failure determination result is a big hit, a big hit variation pattern is set, and if the success / failure determination result is out of reach, Set a reach-less deviation variation pattern that does not involve reach production. Then, the stop symbol of the first special symbol is determined as any one of the probable big hit symbol, the normal big hit symbol, and the off symbol.

  Next, according to the stop symbol and the variation pattern determined in S5082, the first special symbol display unit 61 starts the variation display of the first special symbol (S5083). A variation pattern designation command and a stop information designation command for the first special symbol are transmitted to the sub-control board 260 (S5084). The variation pattern designation command is a command for designating the variation pattern set in S5082, and the first special symbol information designation command is a command for designating a stop symbol of the first special symbol.

  Next, 1 is subtracted from the first special symbol reservation number (S5085), and a first special symbol reservation number command is transmitted to the sub-control board 260 (S5086).

  Next, returning to FIG. 6A, if it is determined in S506 that the second special symbol hold count is not zero (S506: NO), a second special symbol variation display process is performed (S509). . If it is determined in S506 that the second special symbol hold number is not zero (S506: NO), the first special symbol hold number is not zero (even if it is 1 or more). 2. The special symbol variation display process is executed. As a result, the second special symbol is changed and displayed in preference to the first special symbol, and the priority changing function of the second special symbol is realized by the determination process of S506.

  Here, the second special symbol variation display process will be described based on the flowchart of FIG. 10. First, the second special symbol validity determination random number stored in a predetermined area (second reserved storage area) of the RAM of the main control board 200. (Randomness for determination of success / failure acquired at the time of entering the game ball into the first start port 28a) is read (S5090), and the second special symbol determination is performed (S5091). In the second special symbol success / failure determination, if the probability variation function is in operation (probability variation game), the success / failure determination at the time of probability variation, that is, in the state where the probability that the determination result is a big hit (high probability state) When the decision is made and it is determined that the probability variation function is not operating (during normal game), it is determined whether or not it is a non-probability variation, that is, in a state where the probability that the determination result is a big hit (low probability state) Make a pass / fail decision.

  Next, a variation pattern setting process for the second special symbol is performed (S5092). In the second special symbol variation pattern setting process, when the success / failure determination result is a big hit, a big hit variation pattern is set, and when the success / failure determination result is out of range, a reach out / out variation pattern with a reach effect or Set a reach-less deviation variation pattern that does not involve reach production. Then, the stop symbol of the second special symbol is determined as any one of the probable big hit symbol, the normal big hit symbol, and the off symbol.

  Next, according to the stop symbol and the variation pattern determined in S5092, the second special symbol display unit 62 starts the variation display of the second special symbol (S5093). A variation pattern designation command and a stop information designation command for the second special symbol are transmitted to the sub-control board 260 (S5094). The variation pattern designation command is a command for designating the variation pattern set in S5092, and the second special symbol information designation command is a command for designating a stop symbol of the second special symbol.

  Next, the second special symbol reservation number is decremented by 1 (S5095), and a second special symbol reservation number command is transmitted to the sub-control board 260 (S5096).

  Next, returning to FIG. 6A, stop display time setting processing following the first special symbol variation display processing or the second special symbol variation display processing is performed (S5097). Here, the stop display time setting process will be described based on the flowchart of FIG.

  First, it is determined whether or not the release extension flag is set to ON (S5097a). As a result, when it is determined that the release extension flag is not set to ON (S5097a: NO), the normal stop display time “2 seconds” is set as the symbol stop display time of the special symbol (S5097b). On the other hand, if it is determined that the release extension flag is set to ON (S5097b: YES), it is determined whether or not the first special symbol hold probability change flag is set to ON (S5097c).

  As a result, when it is determined that the first special symbol hold probability change flag is set to ON (S5097c: YES), the stop display time A “1 second” is set as the symbol stop display time of the special symbol ( S5097d). On the other hand, if it is determined that the first special symbol hold probability change flag is not set to ON (S5097c: NO), it is determined whether or not the first special symbol hold normal hit flag is set to ON ( S5097e).

  As a result, when it is determined that the first special symbol hold normal flag is set to ON (S5097e: YES), the stop display time B “3 seconds” is set as the symbol stop display time of the special symbol ( S5097f). On the other hand, when it is determined that the first special symbol hold normal flag is not set to ON (S5097e: NO), the normal stop display time “2 seconds” is set as the symbol stop display time of the special symbol (S5097b). ).

  Next, returning to FIG. 6A, when it is determined in S503 that the first special symbol or the second special symbol is changing (S503: YES), the change display time of the changing special symbol Is determined (S510 in FIG. 6B). As a result, if it is determined that the special symbol variation display time has not elapsed (S510: NO), it is determined that the special symbol game processing is terminated and the special symbol variation display time has elapsed. In this case (S510: YES), the variation of the special symbol is stopped (S511), and the measurement of the special symbol stop display time set in the stop display time setting process (S5097) described above is started (S512). In the stop display time setting process, the normal stop display time (2 seconds) is set as the stop display time during normal times. In addition, when a preliminary determination is made when the open time extension function is activated and an affirmative determination (big hit determination) is obtained as a result of the preliminary determination, the stop display time A (1) according to the big hit type (probability big hit or normal big hit) Second) or stop display time B (3 seconds) is set.

  Next, it is determined whether or not the special symbol stop symbol display time has elapsed (S513). As a result, when it is determined that the special symbol stop symbol display time has not elapsed (S513: NO), the special symbol game processing is terminated and it is determined that the special symbol stop symbol display time has elapsed. If it is determined (S513: YES), it is determined whether or not the special symbol stop symbol is a big hit symbol (S514). As a result, when it is determined that the stop symbol of the special symbol is a big hit symbol (S514: YES), the big hit game flag is set to ON (S515). As a result, the big hit game starts.

  Next, it is determined whether or not the probability variation flag is ON (S516). If it is determined that the probability variation flag is ON (S516: YES), the probability variation flag is set to OFF (S517) and the variation is reduced. The flag is set to OFF (S518), and the release extension flag is set to OFF (S519). Thereby, with the start of the big hit game, the probability variation function, the variation time shortening function, and the open time extension function are deactivated.

  On the other hand, when it is determined that the probability variation flag is not ON (S516: NO), it is determined whether or not the fluctuation shortening flag is ON (S520). As a result, when it is determined that the fluctuation shortening flag is not ON (S520: NO), the special symbol game process is terminated, and when it is determined that the fluctuation shortening flag is ON (S520: YES), The fluctuation shortening flag is set to OFF (S518), and the open extension flag is set to OFF (S519). As a result, with the start of the big hit game, the variable time shortening function and the open time extending function are deactivated.

  When it is determined in the determination process of S514 that the special symbol stop symbol is not a big hit symbol (S514: NO), it is determined whether or not the fluctuation shortening flag is ON (S521). As a result, when it is determined that the fluctuation shortening flag is not ON (S521: NO), the special symbol game process is terminated, and when it is determined that the fluctuation shortening flag is ON (S521: YES), The number of fluctuations of the special symbol is counted (S522), and it is determined whether or not the number of fluctuations has reached a preset number of fluctuations (100 in this example) (S523).

  As a result, if it is determined that the number of changes has not reached the preset number of changes (100 times) (S523: NO), the special symbol game process is terminated, and the number of changes is the preset number of changes. When it is determined that the number of times (100 times) has been reached (S523: YES), the fluctuation shortening flag is set to OFF (S524), and the release extension flag is set to OFF (S525). As a result, the variable time shortening function and the open time extending function are deactivated.

  Next, the special electric accessory game process S600 will be described based on the flowchart of FIG. First, it is determined whether or not a jackpot game is being played (S601). If it is determined that a jackpot game is not being played (S601: NO), the special electric accessory game process is terminated and the jackpot game is being played. If it is determined (S601: YES), it is determined whether or not the special winning opening 33a is open (S602). As a result, when it is determined that the special winning opening 33a is being opened (S602: YES), it is determined whether or not the opening time of the special winning opening 33a has elapsed (S603), and the special winning opening 33a is determined. If it is determined that the opening time has not elapsed (S603: NO), it is determined whether or not the maximum number of winnings has been won in the special winning opening 33a (S604).

  As a result, if it is determined that the maximum number of winnings has not been won in the big winning opening 33a (S604: NO), the special electric accessory game process is terminated, and the maximum winning number is won in the large winning opening 33a. If it is determined (S604: YES) or if it is determined that the opening time of the special winning opening 33a has elapsed (S603: YES), the special winning opening 33a is closed (S605).

  If it is determined in S602 that the special winning opening 33a is not open (S602: NO), it is determined whether or not the number of rounds of the big hit game has reached a predetermined number (S606). As a result, when it is determined that the number of rounds of the big hit game has not reached the predetermined number (S606: NO), it is determined whether or not the closing time (interval time) of the big winning opening 33a has elapsed ( S607), when it is determined that the closing time of the special winning opening 33a has not elapsed (S607: NO), the special electric accessory game process is terminated and the closing time of the special winning opening 33a has elapsed. Is determined (S607: YES), the special winning opening 33a is opened (S608).

  When it is determined in S606 that the number of rounds of the big hit game has reached the predetermined number (S606: YES), the big hit game is ended (S609). Then, it is determined whether or not the result of the special symbol success / failure determination (the type of the jackpot symbol stopped and displayed) that triggered the start of the big hit game is a probable big hit (S610). As a result, when it is determined that the result of the special symbol success / failure determination is a probable big hit (S610: YES), the probable change flag is set to ON (S611), the fluctuation shortening flag is set to ON (S612), The release extension flag is set to ON (S613). As a result, the probability variation function, variation time shortening function, and open time extension function start to operate.

  On the other hand, if it is determined in S610 that the special symbol success / failure determination is not a probable big hit (usually big hit) (S610: NO), the fluctuation shortening flag is set to ON (S612), and the release extension flag is set. Set to ON (S613). As a result, the variable time shortening function and the open time extending function start to operate.

  Next, the first special symbol holding related process performed mainly by the CPU 260a of the sub control board 260 will be described. FIG. 14 is a flowchart showing the flow of the first special symbol holding related process executed by the CPU 260a of the sub control board 260 based on the program stored in the ROM. This process is executed by the CPU 260a of the sub control board 260. Not executed as a main routine subroutine.

  First, it is determined whether or not a first special symbol reservation number command has been received from the main control board 200 (S800). As a result, when the first special symbol hold number command is not received (S800: NO), the process proceeds to S802, and when the first special symbol hold number command is received (S800: YES). ), The hold display of the first special symbol is updated (S801). Specifically, the first special symbol hold display command is transmitted from the CPU 260a of the sub control board 260 to the CPU of the effect display control board 280, and the CPU of the effect display control board 280 produces an effect based on the first special symbol hold display command. The hold display of the first hold display unit 25d of the display device 25 is updated to the latest information.

  Next, it is determined whether or not a first special symbol predetermination result command has been received from the main control board 200 (S802). As a result, when the first special symbol advance determination result command is not received (S802: NO), the first special symbol hold related process is terminated and the first special symbol advance determination result command is received. (S802: YES), it is determined whether or not the winning is on hold (S803). As a result, when it is determined that the game is on hold (S803: YES), a hold notice effect for displaying the corresponding hold display of the first special symbol hold display unit 25d in a special mode is performed (S804). In the hold notice effect, a hold notice command is transmitted to the CPU of the effect display control board 280, and the CPU of the effect display control board 280 changes the hold display of the first hold display unit 25d of the effect display device 25 based on the hold notice command. To do. The hold notice effect can be performed, for example, by changing the circular figure “◯” of the first hold display unit 25 d displayed on the effect display device 25 to the star figure “☆”. As a result, the player recognizes that the random number corresponding to the star figure “☆” of the first random numbers for determining whether or not the first symbol is on hold matches the winning value, and there is a possibility that a big hit will occur. Can do.

  Next, it is determined whether or not the open time extension function is activated (S805). Whether or not the opening time extension function is activated is determined by, for example, a command indicating a gaming state transmitted from the CPU 200a of the main control board 200 at the end of a big hit game or at the start of a special symbol change (a big hit ending designation command, a gaming state designation command) Or the like) can be determined by the CPU 260a of the sub-control board 260.

  As a result, when it is determined that the open time extension function is not activated (S805: NO), the first special symbol hold related process is terminated and it is determined that the open time extension function is activated. (S805: YES), it is determined whether or not the type of winning suspension is a probable big hit, that is, whether or not the first special symbol predetermination result specified by the first special symbol predetermination command is a probable big hit. (S806).

  As a result, if the winning hold is a probable big hit (S806: YES), the first special notification process is executed (S807). In the first special notification process, notification is made that the reservation of the second special symbol is digested (the game ball is prevented from entering the second start port 28b). Thereby, the hold of the second special symbol is eliminated at an early stage, and the determination of whether or not it is based on the hold of the first special symbol is performed, so that the probable big hit that is the target of the hold notice effect can be generated early.

  On the other hand, if the hit hold is not a probable big hit, that is, if the hit hold is a normal big hit (S806: NO), the second special notification process is executed (S808). In the second special notification process, a notification that the game with the second special symbol is continued (the game ball is allowed to enter the second start port 28b) is performed. Thereby, the success / failure determination based on the hold of the second special symbol is continuously performed, and the occurrence of the normal jackpot that is the target of the hold notice effect can be delayed.

  If it is determined in the determination process of S803 that the hit is not on hold (S803: NO), it is determined whether or not the open time extension function is operating (S809). As a result, when it is determined that the opening time extension function is not activated (S809: NO), the first special symbol hold-related process is terminated. On the other hand, if it is determined that the open time extension function is activated (S809: YES), whether or not the first special notification process is being executed, that is, a probability change big hit is generated in the holding of the first special symbol. It is determined whether or not a hold is included (S810).

  As a result, when it is determined that the first special notification process is being executed (S810: YES), the first special symbol hold-related process is terminated. On the other hand, if it is determined that the first special notification process is not being executed, that is, it is determined that the hold of the first special symbol does not include a hit hold that generates a probable big hit (S810: NO), the first special symbol hold It is determined whether or not the number has reached the upper limit (S811).

  As a result, if it is determined that the number of first special symbol reservations has not reached the upper limit (S811: NO), the first special symbol reservation related processing is terminated. On the other hand, if it is determined that the first special symbol hold count has reached the upper limit (S811: YES), a third special notification process is executed (S812). In the third special notification process, a notification that the reservation of the first special symbol is digested (the game ball is allowed to enter the first start port 28a) is performed. Thereby, the first special symbol pre-determination can be performed by erasing the first special symbol hold, which is all out of hold, and newly holding the first special symbol. In addition, while the opening time extension function is in operation, the priority change of the second special symbol is performed. However, since the gaming ball hardly enters the second start port 28b after the opening time extension function has been operated, Fluctuation display is performed. Therefore, by stocking the first special symbol hit hold during the opening time extension function operation, the jackpot due to the first special symbol hold can be generated early after the opening time extension function operation ends. Can do.

  Here, the correspondence between the processing shown in the flowcharts of FIGS. 6 to 13 and the present invention will be described. The processing of S552 is an aspect of the first reserved storage means of the present invention, and the processing of S558 is the present invention. S508 is one aspect of the first symbol display control means of the present invention, S509 is one aspect of the second symbol display control means of the present invention, and S506 is the second aspect of the present invention. In one aspect of the symbol priority changing means, S554 is one aspect of the first symbol prior determination means of the present invention, and S5097 is one aspect of the stop display time setting means of the present invention.

  In the present embodiment described above, when an affirmative determination (big hit determination) is obtained by the first special symbol prior determination, depending on the type of big hit (probable big hit or normal big hit), the open time extension function is activated. By setting the special symbol stop display time, it is possible to change the big hit occurrence time resulting from the fluctuation display of the first special symbol which is the target of the first special symbol prior determination according to the type of big hit. Thereby, a novel game property can be provided and a game interest can be improved.

  Specifically, when the determination result of the first special symbol pre-determination is a probable big hit, the symbol stop display time of the first special symbol and the second special symbol that are variably displayed first is shortened, 2 It is possible to generate a state in which the special symbol hold is zero, and it is possible to expedite the occurrence of a probable big hit due to the fluctuation display of the first special symbol that is the target of the first special symbol prior determination. As a result, it is possible to quickly generate a probable big hit that is advantageous to the player.

  In addition, when the determination result of the first special symbol pre-determination is a normal jackpot, the first special symbol and the second special symbol that are variably displayed earlier are extended to extend the first symbol stop display time. It is possible to delay the occurrence of the normal jackpot due to the variation display of the first special symbol that is the target of the special symbol prior determination. As a result, it is possible to increase the number of times the second special symbol is retained by increasing the chance to enter the second starting port 28b, and to increase the chance that a probability variation jackpot will occur due to the retention of the second special symbol. Can do. Further, if the current gaming state is in the probability variation game, the probability variation advantageous to the player is delayed by delaying the occurrence of the normal jackpot due to the variation display of the first special symbol subject to the first special symbol prior determination. Game time can be extended.

  In addition to the setting of the stop display time described above, the first special symbol hold-related process by the sub-control board 260 notifies the player of the game mode in which the game can be advantageously advanced, thereby It is possible to more effectively speed up and delay the occurrence of big hits caused by variable display.

(Second embodiment)
Next, a second embodiment of the present invention will be described. Only the parts different from the first embodiment will be described below.

  In the gaming machine 1 of the present embodiment, two types of jackpot games are prepared depending on the type of jackpot symbol of the special symbol. When the big hit symbol is a normal big hit symbol or a probable variation big hit symbol, that is, when the result of the special symbol success / failure determination is a normal big hit or a probable big hit symbol, the first big hit game is started. When the big hit symbol is the specific big hit symbol, that is, when the result of the special symbol hit / fail judgment is the specific big hit symbol, the second big hit game is started. In the second jackpot game, the number of times the maximum winning opening 33a is opened (the maximum number of consecutive rounds) is set smaller than that in the first jackpot game, and the opening time of the big winning opening 33a is set shorter. That is, the first jackpot game is a jackpot game state that involves a lot of prize balls paid out (high possibility of prize ball payout) when a large number of game balls enter the big prize opening 33a. The big hit game is a big hit gaming state in which the possibility that a game ball will enter the big winning opening 33a is extremely low and there is substantially no prize ball payout (the possibility that a prize ball payout will be performed is low).

  In this embodiment, the maximum duration of the first big hit game is 15 rounds and the opening time of the big prize opening 33a is set to 30 seconds, for example, and the maximum last round of the second big hit game is 2 rounds and the big winning opening 33a The opening time is set to 0.2 seconds, for example. When the second big hit game is generated, the second big hit game state is completed in a short time, so that almost no winning ball is obtained. In this embodiment, the first jackpot game is also called 15R jackpot, and the second jackpot game is also called 2R jackpot. In the second embodiment, the first special symbol hold per flag includes a first special symbol hold per 15R flag that is set when the first special symbol determination random number corresponds to the probability variable big hit symbol or the normal big hit symbol, A first special symbol hold 2R per flag that is set when the first special symbol determining random number corresponds to the specific jackpot symbol is included.

  FIG. 14 is a flowchart showing the flow of the first special symbol pre-determination process of the second embodiment, and corresponds to FIG. 8 of the first embodiment. As shown in FIG. 14, in the second embodiment, when it is determined that the first special symbol success / failure random number matches the winning value (S5540: YES), the first special symbol success / failure determination is performed. It is determined whether or not the first special symbol determination random number stored in S552 (see FIG. 7) together with the random number for use corresponds to the specific jackpot symbol (S5541 ′).

  As a result, when it is determined that the first special symbol determination random number does not correspond to the specific jackpot symbol, that is, when the type of jackpot is determined to be 15R jackpot (the first special symbol determination random number is the first If it is determined that the first big hit information is derived from the first big hit (S5541 ′: NO), the first special symbol hold 15R hit flag is set to ON (S5542 ′). On the other hand, when it is determined that the first special symbol determination random number corresponds to the specific jackpot symbol, that is, when the type of jackpot is determined to be 2R jackpot (the first special symbol determination random number is the second If it is determined that it is the second big hit information for deriving the big hit (S5541 ′: YES), the first special symbol reservation 2R hit flag is set to ON (S5543 ′).

  FIG. 15 is a flowchart showing the flow of the stop display time setting process of the second embodiment, and corresponds to FIG. 11 of the first embodiment. As shown in FIG. 15, in the second embodiment, it is determined whether or not the flag for the first special symbol reservation 15R is set to ON when the open time extension function is activated (S5097c '). As a result, if it is determined that the first special symbol hold 15R per flag is set to ON (S5097c ': YES), the special symbol stop display time is set to a stop display time A "shorter than the normal stop display time. 1 second "is set (S5097d). On the other hand, if it is determined that the first special symbol reservation 15R per flag is not set to ON (S5097c ': NO), it is determined whether or not the first special symbol reservation 2R per flag is set to ON. (S5097e ').

  As a result, when it is determined that the first special symbol hold 2R flag is set to ON (S5097e ′: YES), the stop display time B “3 seconds” is set as the symbol stop display time of the special symbol. (S5097f). On the other hand, when it is determined that the first special symbol hold 2R flag is not set to ON (S5097e ′: NO), the normal stop display time “2 seconds” is set as the symbol stop display time of the special symbol ( S5097b).

  Even in the configuration of the second embodiment described above, when an affirmative determination (big hit determination) is obtained by the first special symbol prior determination, the first special symbol preliminary determination is made depending on the type of the big hit. It is possible to change the big hit occurrence time due to the change display of one special symbol, and it is possible to provide new game playability.

  Specifically, when the determination result of the first special symbol pre-determination is a 15R big hit advantageous to the player (a big hit with a high possibility of winning a prize ball), the special symbol stop display time is shortened. Thus, the execution timing of the first special symbol success / failure determination can be advanced, and a 15R big hit advantageous to the player can be generated early. Also, if the determination result of the first special symbol pre-determination is a 2R jackpot that is disadvantageous to the player, the 2R jackpot that is disadvantageous to the player (a prize ball payout is performed) by shortening the special symbol stop display time. The occurrence of a big hit that is unlikely to be missed) can be delayed.

(Other embodiments)
As mentioned above, although the Example of this invention was described, this invention is not limited to this, Unless it deviates from the range described in each claim, it is not limited to the description word of each claim, and those skilled in the art Improvements based on the knowledge that a person skilled in the art normally has can be added as appropriate to the extent that they can be easily replaced.

  For example, in the pre-determination process of S5540 in each of the above embodiments, it is determined whether or not the first special symbol success / failure random number coincides with a portion “1, 3” of the probability variation game hit value during the probability variation game. However, the present invention is not limited to this, and all of the permutations for probability-changing games may be “1, 3, 5, 7, 9, 10,.

  In addition, when the pre-determined result is a normal hit in each of the above embodiments and the special symbol stop display time is extended, if the second special symbol hold number already exists, the second start port is entered. There is a possibility that the award ball will be excessively paid out to the player due to an increase in the chance to play the ball, and the game will work too advantageously. Therefore, in the first special symbol predetermination process S554 of the first embodiment, when the result of the predetermination is normal hit (S5541: NO), or in the first special symbol predetermination process S554 of the second embodiment, When the determination result is around 2R (S5541 ′: YES), the special symbol stop display time can be set based on the second special symbol hold count. Specifically, when the number of second special symbol hold is greater than or equal to a predetermined number (for example, 3 or more), it remains during the normal stop display (for example, 2 seconds), and the second special symbol hold number falls below the predetermined number. If there is (for example, less than 3), a stop display time B (for example, 3 seconds) may be set. Thereby, when there are many 2nd special symbol holding | maintenance numbers, the excessive increase in the opportunity to enter a 2nd start port can be prevented, and it can prevent that a game works too much on a player.
