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 pachinko machines, the fluctuation time reduction function and the opening time extension function are activated after the end of the big hit game, the fluctuation time of the normal symbol is shortened, the frequency of the normal symbol being stopped and displayed in the symbol increases, and the normal electric role In many cases, the opening time of a starting port (so-called electric chew) constituted by an object is extended (see, for example, Patent Document 1). As described above, when the variable time shortening function and the opening time extending function are started, the opening frequency (number of times of opening, opening time) of the starting port is significantly improved compared to the normal state. It becomes. In the “opening frequency improvement state”, the game ball can be played without reducing the number of game balls on hand by increasing the frequency of entering the game balls into the start opening (electrical chew). For this reason, the “opening frequency improvement state” is also referred to as “electric chew support state” or “electric support state”.

JP-A-9-206438

  However, in the gaming machine configured as described above, when focusing on the opening frequency of the starting opening (electrical chew), the opening frequency of the starting opening (electrical chow) is higher than usual, and the starting opening (electrical chow) Since there are only two types of states of “no electric support”, the release frequency of which is a normal frequency, there is a problem that the game is monotonous and lacks game play.

  Therefore, in view of the above points, the present invention has an object to provide new game playability with respect to the opening frequency of the start opening, and to improve game entertainment.

In order to achieve the above object, the gaming machine of the present invention provides:
Based on the game ball flowing down the right side area of the game board has passed the game ball to Hiroshi through design operating gate passable, normal symbol display control to stop displaying after a normal symbol was displayed varies normal symbol display unit Means,
Based on the game ball has entered the special startup port, a special symbol display control means for stopping displayed after variably displayed special symbol in special symbol display unit,
When the special symbol is stopped and displayed in a predetermined hit state , a hit game execution means for executing a hit game that allows the game ball to enter the big prize opening ;
With
As the starting opening, a first starting opening capable of entering a game ball flowing down the left area of the game board surface;
A game ball flowing down the right area of the game board surface can enter, and the game ball can be changed into a state where it is difficult to enter and an open state where the game ball is easy to enter. A second start port that changes to the open state when stopped and displayed in a mode,
As the special symbol display unit, a first special symbol display unit corresponding to the first start port and a second special symbol display unit corresponding to the second start port are provided,
A gaming machine provided with a first special symbol displayed on the first special symbol display unit and a second special symbol displayed on the second special symbol display unit as the special symbol,
A first counting means for counting a first predetermined value by counting the number of times the variable display of the special symbol that is performed following the end of the previous Kito Ri game,
A second counting means for counting a second predetermined value smaller than the first predetermined value by counting the number of times the variable display of the special symbol that is performed following the end of the previous Kito Ri game,
While the counting by pre Symbol first counting means is performed, and the open time extension means for extending the open time of the second start hole,
Normal symbol normal variation means for variably displaying the normal symbol in a variation time for normal variation when counting by the first counting unit and counting by the second counting unit are not performed;
And during, normal symbol special variation means for the normal symbol variable display a long special variation for varying time than the usual same or the normal variation time for change and variation for varying time the counting by pre Symbol second counting means is performed ,
Normal symbol shortening variation means for displaying the normal symbol variably with a shortening variation variation time shorter than the normal variation variation time while counting by the second counting device is not performed and counting by the first counting device is performed. When,
Equipped with a,
When the counting by the first counting means and the counting by the second counting means are not performed and the special symbol is stopped and displayed in the first winning mode, the first symbol is displayed after the winning game is finished. When the counting by the counting means and the counting by the second counting means are started from the initial value, the normal symbol is displayed in a varying manner for the variation time for the special variation, and the special symbol is stopped in the second hit mode. If displayed, after the winning game is over, the counting by the first counting means and the counting by the second counting means are not started, so that the normal symbol is variably displayed with the fluctuation time for normal fluctuation. become,
The special symbol when the counting by the first counting means is performed and the counting by the second counting means is performed before the count value by the second counting means reaches the second predetermined value. Is stopped and displayed in the first hit mode, the counting by the second counting means is continuously started from the count value at the stop display time of the first hit mode after the hit game is ended. When the counting by the first counting means is started from the initial value, the normal symbol is variably displayed in the variation time for the special variation, and the special symbol is stopped and displayed in the second hit mode. After the winning game is over, the counting by the second counting means is not started, and the counting by the first counting means is started from the initial value, so that the normal symbol is variably displayed in the variation time for the shortening variation. Like Now,
When the counting by the first counting means is performed and the counting by the second counting means is not performed after the count value by the second counting means reaches the second predetermined value, the special When the symbol is stopped and displayed in the first hit mode or the second hit mode, the counting by the second counting means is not started after the winning game is ended, and the counting by the first counting means starts from the initial value. As a result, the normal symbol is variably displayed in the variation time for shortening variation .

According to the present invention, there are three stages of gaming states with different opening frequencies of the second start opening , that is, the normal symbol is displayed in a variable manner with the normal change fluctuation time and the opening time of the second start opening is not extended. The first stage gaming state ( the frequency of opening of the second starting port is the lowest level), the normal symbol is displayed in a variable time for special variation, and the second stage gaming state in which the opening time of the second starting port is extended ( first opening frequency mid-level 2 start hole), the open frequency of the third stage playing state (second start port opening time of the second start hole is extended with normal symbol varies displayed in abbreviated variation for time varying The highest level). Thus, the ends of those Ri game, by opening time of the second start hole is extended, the opening frequency of the second start hole is increased from the lowest level to the middle level, more specific variation period ends, usually By shortening the symbol variation time, it is possible to provide a new gameability such that the opening frequency of the second start port becomes the highest level, and it is possible to improve the game entertainment.

That is, after the end of this Ri game, the number of executions of the variation display of the special symbol in a state where the opening frequency of the second start hole was improved from the lowest level to the middle level (special variation period) the counting result of the second counting means When the second predetermined value is reached, the opening frequency of the second start port is improved from the intermediate level to the highest level. Thus, after the person Ri game once is completed, be variations impressions next special symbols without those Ri game is started becomes a second predetermined value, the opening frequency of the second start hole It can be understood that the condition for shifting to the highest level is established, that is, so-called “ceiling arrival”. Therefore, according to the present invention, it is possible to provide a novel game such as “the opening frequency of the second start port reaches the highest level when reaching the ceiling”.

Furthermore, in the present invention, a normal symbol actuating gate through which a game ball flowing down the right area of the game board surface can pass, a first starting port into which a game ball flowing down the left area of the game board surface can enter, A second starting port is provided through which a game ball flowing down the right region can enter. Thus, for example, when the normal symbol is displayed in a variable manner for the normal variation variation time or the special variation variation time, the game ball is fired by performing “left-handed” to launch the game ball toward the left region of the game board surface. It becomes the “first special symbol variation gaming state” which is advantageous for the player to enter the first starting port , and when the normal symbol is variably displayed with the variation time for shortening variation, it is directed to the right area of the game board surface. It is the “second special symbol variable gaming state” that is advantageous for the player to perform “right-handed” to launch the game ball and enter the game ball into the second starting port .

According to such a configuration, for example, when the normal symbol is variably displayed in the normal variation variation time or the special variation variation time, the “left-handed” for launching the game ball toward the left region of the game board surface is performed. If it is the “first special symbol variation gaming state” that is advantageous for the player to go into the first starting opening and the normal symbol is variably displayed with the variation time for shortening variation, It is a “second special symbol variable gaming state” that is advantageous for the player to perform “right-handed” to fire the game ball toward the right region and to enter the game ball into the second starting port . As a result, the game is progressed by “left-handed” until it shifts to “the third stage gaming state ( the opening frequency of the second start opening is the highest level)” (until it reaches the ceiling), With the transition to the “gaming state” (reaching the ceiling), it is possible to provide a new gameability of starting “right-handed”, thereby improving the game entertainment.

  Note that the counting of the number of times of display of the special symbol by the first counting means ends when the count value becomes “first predetermined value”, and the number of times of the number of special symbols by the second counting means is counted. The process ends when the count value reaches a “second predetermined value” that is smaller than the “first predetermined value”, but both the “first predetermined value” and the “second predetermined value” are “fixed values”. Can be either “variable value”. In the case of “variable value”, for example, a plurality of values to be set as “first predetermined value” and “second predetermined value” are prepared in advance, and various conditions are satisfied (the power-on of the gaming machine, the specific value) The value set as the “first predetermined value” or the “second predetermined value” can be determined by a lottery or the like each time when the special winning symbol stop display, the execution of the big hit game, or the like) is performed. The counting by the first counting means and the second counting means may be either the “subtraction method” or the “addition method”.

  The first counting means and the second counting means may be configured such that one of the two counters counts the first predetermined value and the other counter counts the second predetermined value. The form which counts the 1st predetermined value and the 2nd predetermined value can be illustrated. Among these, in the latter form, one counter, means for determining that the count value of the counter has reached the first predetermined value, and determination that the count value of the counter has become the second predetermined value The "first counting means" and the "second counting means" can be configured by the means for performing.

In addition, the probability (probability per ordinary symbol) that the determination result (ordinary symbol determination result) by the normal symbol validity determination execution unit is a hit may be constant (fixed) or may vary. However, when the probability per normal symbol is constant (fixed), it is preferable to set so that the result of the normal symbol success / failure determination is a hit with a relatively high probability. On the other hand, when the probability per ordinary symbol varies, it is preferable that at least two kinds of probabilities, “low probability” and “high probability”, can be set as the probability per ordinary symbol (including a normal symbol probability variation means). In this case, in the above-mentioned “first stage gaming state ( the opening frequency of the second start opening is the lowest level)”, the probability per normal symbol is set to “low probability”, and the above “second stage gaming state ( In the case of “the second start opening frequency is an intermediate level” and “the third stage gaming state ( the second start opening frequency is the highest level)”, it is preferable to set the probability per normal symbol to “high probability”.

In the gaming machine of the present invention, when the counting by the first counting means is performed, and the counting by the second counting means is performed before the count value by the second counting means becomes the second predetermined value. When the special symbol is stopped and displayed in the second winning mode, the counting by the second counting means is not started after the winning game is ended, and the counting by the first counting means is started from the initial value. Ordinary symbols are displayed in a variable manner with a short variation time.

As a result, the second stage gaming state is completed in a short period of time, triggered by the stop indication of the second hit mode , and the third stage gaming state where the opening frequency of the second start port is “highest level”. It will move immediately. Thus, after those Ri game end, depending on the timing of the special symbol is stopped and displayed at a second per special embodiment, it is time to migrate differ from the gaming state of the second stage to the playing state of the third stage, the second stage Thus, it is possible to provide a new gaming property in which the gaming period from the gaming state to the transition to the third stage gaming state is diversified.

In the gaming machine of the present invention, the winning game execution means may be more effective when the special symbol is stopped and displayed in the second winning manner than when the special symbol is stopped and displayed in the first winning manner. It is characterized by performing a hit game that is disadvantageous to the player.
In this way, the second stage gaming state from the second stage gaming state described above is triggered by the stop display of the second hit mode that starts the hit game which is disadvantageous to the player than when the special symbol is stopped and displayed in the first hit mode . by shifting to the playing state of the three stages, even those Ri game that is executed by the stop display of the second per aspect is disadvantageous for the player, the player, special symbol is stopped and displayed at a second per aspect (Because of the occurrence of games per specific). Thereby, a new meaning (game value) can be added to the specific hit game which is more disadvantageous to the player than the big hit game, and the game interest can be improved. The “specific hit game” can be configured as a hit game excluding the big hit game that is most advantageous to the player when a plurality of types of hit games are executed corresponding to a plurality of types of hit special symbols.

In addition, in the gaming machine of another invention related to the present invention,
The probability that pre-Symbol first special symbol is stopped and displayed in the second per special symbol is characterized in that it is set higher than the probability that the second special symbol is stopped and displayed in the second per special symbol.

As a result, the game related to the first special symbol ( first start port ) has a higher probability of occurrence of a specific hit game than the game related to the second special symbol ( second start port ). Become. In this way, the game state in the second stage (the first stage game is more likely to be played in the first special symbol which is disadvantageous for the player by “left-handed” than in the game related to the second special symbol by “right-handed” . (2 ) The opening frequency of the starting port is in an intermediate level) can be completed in a short period of time, and a new stage can be shifted to the third stage gaming state ( the state in which the opening frequency of the second starting port is the highest level). Significance (game value) can be added, and game entertainment can be improved.

  According to the above-described configuration of the present invention, it is possible to provide new game playability with respect to the opening frequency of the start opening, and to improve game entertainment.

A start-up solenoid 28c (see FIG. 3) is provided. When the pair of wing pieces are opened to the left and right, the size of the game ball receiving port of the second start port 28b is enlarged from the normal time, and the second start port 28b has a possibility of entering a game ball. It becomes an open state that becomes larger. On the other hand, when the pair of wing pieces are erected, the size of the game ball receiving port of the second start port 28b is slightly larger than the diameter of the game ball (one game ball can pass). The second start port 28b is in a normal state (closed state) in which the possibility of entering a game ball is reduced (or entry is impossible). When a game ball enters the first start port 28a, a first special symbol, which will be described later, starts variably displaying, and when a game ball enters the second start port 28b, a second special symbol, which will be described later, is variably displayed. To start.

  The big winning device 33 is disposed below the first start port 28a. Here, the special winning device 33 includes a special winning opening 33a opened in a belt shape, an opening / closing plate 33b for opening / closing the special winning opening 33a, and a large winning opening solenoid 33c (for operating the opening / closing plate 33b). 3) and an incoming ball detection switch 33s (see FIG. 3) for detecting an incoming game ball.

  A left winning opening 34 and 35 and a right winning opening 36 and 37 are provided on the upper left side and the upper right side of the big winning device 33. Each of these winning openings is provided with a winning opening entering detection switch (not shown).

  The first decorative member 50 is provided with a plurality of LEDs. By combining these LEDs, a normal symbol display unit 51, a general symbol hold display unit 52, a first special symbol hold display unit 53, and a second special symbol are provided. A hold display unit 54 is configured. Similarly, the second decorative member 60 is provided with a plurality of LEDs, and a first special symbol display portion 61 and a second special symbol display portion 62 are configured by a combination of these LEDs.

  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. When the normal symbol is stopped and displayed in the preset normal symbol display mode, the second start port 28b is opened according to a predetermined opening pattern. A plurality of opening patterns of the second start port 28b are set. When the opening time extending function for extending the opening time of the second start port 28b is not in operation (normal time), a short opening pattern in which a first opening time (for example, 0.2 seconds) is set is set and opened. When the time extension function is activated, a long-time opening pattern in which a second opening time (for example, 5 seconds) longer than the first opening time is set is set. The open time extension function will be described later.

  In the present embodiment, as the variation time of the normal symbol, the variation time for normal variation (30 seconds in this embodiment), the variation time for shortening variation shorter than the variation time for normal variation (1 second in this embodiment), A special fluctuation time (120 seconds in this embodiment) longer than the fluctuation time is provided. Then, when the normal symbol success / failure determination is executed, a specific variation time is set according to the gaming state. Specifically, during the special fluctuation period after the big hit game ends, a special fluctuation time (120 seconds) is set. The fluctuation time (1 second) is set, and the fluctuation time for normal fluctuation (30 seconds) is selected while the fluctuation time shortening function is not in operation. The special variation period and variation time shortening function will be described later.

  In the present embodiment, a random number for determining normal symbol success / failure is prepared, and this random number for determining normal symbol determination is acquired when the game ball passes through the normal symbol operating gate 27, and the second start port 28b. Is used to determine whether or not to operate a normal symbol (whether or not to make it open). A hit value is set in advance for the random number for normal symbol success / failure determination, and a hit is determined when the random number for normal symbol success / failure determination obtained at the timing when the game ball passes the normal symbol operation gate 27 matches the winning value. Is done. The normal symbol success / failure determination is performed in the low probability state using the low probability normal symbol success / failure determination table set with a small hit value while the variable time reduction function and the open time extension function described later are not in operation, and the variable time reduction function When the open time extension function is in operation, it is performed in a high-probability state using a high-probability normal symbol success / failure determination table in which the number (type) of hits is higher than the low-probability normal symbol success / failure determination table (normal symbol probability variation means) ). In this embodiment, the probability of hitting the normal symbol is determined to be “2/89” in the low probability state (when the variable time reduction function and the open time extension function are inactive), and the high probability state (the variable time reduction function and “86/89” is set in the operation of the open time extension function). When it is determined that the normal symbol is determined to be a win, the normal symbol that is stopped and displayed on the normal symbol display unit 51 is determined as the display mode of the 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.

  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. Along with the holding of the normal symbol, a random number for determining whether or not the normal symbol is stored in a predetermined area of the RAM of the main control unit 200.

  It should be noted that the determination of whether or not the normal symbol is determined, the determination of the stop symbol of the normal symbol, the setting of the variation pattern of the normal symbol, the storage and storage of the normal symbol are performed by the main control unit 200 described later. Therefore, the main control unit 200 corresponds to the “normal symbol display control means” of the present invention.

  Next, the special symbol will be described. In this embodiment, two special symbols, a first special symbol and a second special symbol, are provided, and accordingly, a first special symbol display unit 61 for displaying the first special symbol and a second special symbol are displayed. A second special symbol display section 62 is provided. Each of the special symbol display units 61 and 62 includes seven LEDs, and special LEDs (first special symbol and second special symbol) are displayed by these LEDs. Each LED constituting each of the special symbol display units 61 and 62 can be turned on and off, and a plurality of display modes can be displayed for each special symbol by a combination of turning on and off of each LED. And in the 1st special symbol display part 61 and the 2nd special symbol display part 62, the specific combination is set as a big hit symbol among the combinations of the special symbols displayed by the combination of lighting and extinction of 7 LEDs respectively. In addition, combinations other than the jackpot symbol are set as outliers. In this embodiment, a plurality of types of jackpot symbols (LED display patterns) are set, and the number of rounds of jackpot game (2 rounds or 15 rounds) to be described later is determined according to the types. In this embodiment, the special symbol variation display is performed by blinking display in which each LED is repeatedly turned on and off.

  In the first special symbol display unit 61, when the game ball enters the first start port 28a, the first special symbol starts to be displayed in a fluctuating manner, and after the predetermined time has elapsed, the first special symbol stops at the big hit symbol or the off symbol. In the second special symbol display unit 62, when the game ball enters the second starting port 28b, the second special symbol starts to be displayed in a variable manner, and after the predetermined time has passed, the second special symbol is a big hit symbol or missed. Stopped display with symbols. In this embodiment, a plurality of jackpot symbols are set, and specifically, “probable variation jackpot symbol” and “normal jackpot symbol” are set as will be described later.

  As the game ball enters the first starting port 28a, the first special symbol success / failure determination random number and the first special symbol determination random number are acquired. One special symbol determination random number is stored as a hold (first special symbol hold) in a predetermined area (first hold storage area) of the RAM of the main control unit 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) of the RAM of the main control unit 200 is obtained. Is stored as a hold (second special symbol hold) in the hold storage area).

  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 opening 28a can be held until the maximum number of reserved balls (four in this embodiment) is reached as the number of first special symbol held. 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 unit 200. This corresponds to the number (stored number) of special symbol random numbers (first special symbol success / failure determination random number, first special symbol determination random 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 second special symbol reservation number. 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 unit 200. This corresponds to the number (stored number) of special symbol random numbers (second special symbol determination random number, second special symbol determination random 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. On-hold storage and on-hold digestion of the first special symbol and the second special symbol are performed by the main control unit 200 described later.

  The special symbol success / failure determination random number is set with a jackpot value for success / failure determination, and the first special symbol success / failure determination acquired at the timing when the game ball enters the first start port 28a or the second start port 28b. When the random number for use or the random number for determining whether or not the second special symbol is matched with the jackpot value, the jackpot is determined. 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.

  In the first special symbol success / failure determination, when the first special symbol success / failure determination random number coincides with the jackpot value (in the case of a big hit), the first special symbol stopped and displayed on the first special symbol display unit 61 is the jackpot symbol. (Probable big hit symbol or normal big hit symbol). In addition, in the first special symbol success / failure determination, if the first special symbol success / failure random number does not coincide with the big hit value (in the case of losing), the first special symbol success / failure random number is used to play the small hit game. Whether or not it is generated is further determined (small hit determination of the first special symbol). In this small hit determination, a small hit value that will generate a small hit game is set in advance, and if the first special symbol success / failure random number that does not match the big hit value matches the small hit value, It is determined to be a hit. If it is determined that a small hit is made in this small hit determination, the first special symbol that is stopped and displayed by the first special symbol display unit 61 is determined as the small hit symbol. On the other hand, if the result of the first special symbol success / failure determination is not a big hit and the result of the first special symbol's small hit determination is not a big hit, the result of the first special symbol success / failure determination is finally disengaged, The first special symbol that is stopped and displayed by the first special symbol display unit 61 is determined to be a detached symbol.

  Similarly, in the second special symbol success / failure determination, when the second special symbol success / failure determination random number matches the jackpot value (in the case of a big hit), the second special symbol is stopped and displayed on the second special symbol display unit 62. Is determined to be a big hit symbol (probability big hit symbol). In addition, in the second special symbol success / failure determination, if the second special symbol success / failure random number does not match the big hit value (in the case of losing), the second special symbol success / failure random number is used to play the small hit game. The determination as to whether or not to generate the second special symbol small hit determination is performed in the same manner as the first special symbol small hit determination. When it is determined that a small hit is made in this small hit determination, the second special symbol stopped and displayed by the second special symbol display unit 62 is determined as the small hit symbol. On the other hand, if the result of the second special symbol success / failure determination is not a big hit and the result of the second special symbol's small hit determination is not a big hit, the result of the second special symbol success / failure determination is finally disengaged, The second special symbol that is stopped and displayed by the second special symbol display unit 62 is determined to be a detached symbol. In the present embodiment, the probability that the result of the small hit determination of the first special symbol is a small hit is set higher than the probability that the result of the small hit determination of the second special symbol is a small 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 variation display of the first special symbol. . That is, when both the number of first special symbol hold and the number of second special symbol hold are 1 or more, the second special symbol starts to be displayed with priority over the first special symbol, and the second special symbol is displayed. The reservation of is preferentially digested. 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.

  The first special symbol and the second special symbol are each configured to be variably displayed according to a predetermined variation pattern. This variation pattern specifies the variation time of the special symbol and the presence / absence (effect content) of the reach effect or the notice effect in the variation, and multiple types of variation patterns are associated with the random number for determining the variation pattern. Included in the pattern table. The variation pattern of the special symbol is selected by lottery from the variation pattern table when the first special symbol determination or the second special symbol determination is executed and the variation display of the first special symbol or the second special symbol is started. Is done.

  A plurality of variation pattern tables for the first special symbol and the second special symbol are prepared, and the variation pattern table corresponding to the gaming state is selected and used. For these multiple variation pattern tables, the variation pattern table for special variation selected when the special variation period is set, the probability variation function selected when the probability variation function and the variation time shortening function are operating. Selected when the fluctuation pattern table and fluctuation time reduction function are operating.Selected when the fluctuation pattern table for time reduction and the special fluctuation period are not set and the probability fluctuation function and the fluctuation time reduction function are not operating. The normal variation pattern table is included. The relationship of the length of the special symbol variation time defined by the variation pattern included in each variation pattern table is “(variation pattern for probability variation = variation pattern for short time) <variation pattern for special variation <normal variation pattern”. ing. The variation time of the special symbol in the variation pattern for special variation and the normal variation pattern may be the same.

  Also, the first special symbol success / failure determination, the second special symbol success / failure determination, the determination of the variation mode of the first special symbol, the determination of the variation mode of the second special symbol, the determination of the stop symbol of the first special symbol, the second special symbol The stop symbol determination, the first special symbol variation display and stop display, the second special symbol variation display and stop display, and the second special symbol priority variation are configured to be performed by the main control unit 200 described later. ing. For this reason, the main controller 200 corresponds to the “special symbol display control means” of the present invention.

  Next, the big hit game which is a form of the special game (win game) will be described. When the first special symbol stopped and displayed by the first special symbol display unit 61 or the second special symbol stopped and displayed by the second special symbol display unit 62 is the aforementioned jackpot symbol (the result of the special symbol success / failure determination is In the case of a big hit), the main control unit 200 as a winning game execution means starts a big hit game (special game) advantageous to the player. 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. It is. The big hit game is realized by repeatedly executing a hit 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, the big winning opening / closing operation for continuously operating the big winning device 33 and switching the big winning opening 33a between the open state and the closed state is continuously performed a plurality of times by the start of the big hit game. 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 ending condition, when the opening time of the big winning opening 33a reaches a specified time (26 seconds in this embodiment) or the number of game balls that have entered the opened large winning opening 33a is a predetermined number (this implementation) In the example, it is possible to reach 10).

  In the case where one round game is performed from the start to the end of the open state of the big winning opening 33a, the big hit game is ended when a predetermined number of round games are performed. In the grand prize winning device 33, after the opening of the big prize winning opening 33a is completed, that is, after a predetermined interval time has elapsed since the big winning prize opening 33a is closed, the big winning prize opening 33a is again opened, and the next round game Starts. The opening / closing operation of the grand prize winning opening 33a in which one round is from the start to the end of the big winning opening 33a is continuously repeated until the predetermined maximum number of continuous rounds is completed.

  In the gaming machine 1 according to the present embodiment, two types of big hit games having different maximum continuous round numbers are provided. Specifically, a “first big hit game” in which the maximum number of consecutive rounds is set to 15 and a “second big hit game” in which the maximum number of continuous rounds is set to two are provided. When the result of the special symbol success / failure determination is “first jackpot”, the “first jackpot game” is started. When the result of the special symbol success / failure judgment is “second jackpot”, the “second jackpot game” is started. Is done. Since the maximum number of consecutive rounds of the first jackpot game is set to 15 rounds and the maximum number of rounds of the second jackpot game is set to two rounds, the first jackpot game is referred to as “15R jackpot game” below. The second jackpot game is also called “2R jackpot game”, the first jackpot is also called “15R jackpot”, and the second jackpot is also called “2R jackpot”. The second big hit game constitutes a “special hit game” together with a small hit game described later.

  The main control unit 200 determines the jackpot symbol of the special symbol (first special symbol, second special symbol) determined based on the special symbol determining random number (first special symbol determining random number, second special symbol determining random number). Depending on the type, the number of rounds of the jackpot game is determined. In other words, the special symbol jackpot symbol includes a “15R jackpot symbol” that generates a first jackpot (15R jackpot) and a “2R jackpot symbol” that generates a second jackpot (2R jackpot). Is provided. Also, in this embodiment, “first probability variation big hit (15R probability variation big hit)” and “second probability variation big hit (2R probability variation big hit)” are provided as big hits whose probability variation function will be activated after the big hit game ends. Depending on the type of jackpot symbol of the special symbol (first special symbol, second special symbol) determined based on the random number for determining the special symbol (random number for determining the first special symbol, random number for determining the second special symbol) Thus, it is determined whether or not to operate the probability variation function after the end of the big hit game. In other words, in the special symbol big hit symbol, the “15R probability variable big hit symbol” and the “second probability variable big hit symbol (2R probability variable big hit)” are generated. And a “15R normal big hit symbol (hereinafter referred to as a normal big hit symbol) that generates a“ normal big hit (15R normal big hit) ”in which the probability variation function does not operate after the big hit game ends. ) ”.

  These first and second big hit games differ in the opening time (specified time) of the big winning opening 33a in one round. The opening time of the first jackpot game big winning opening 33a (the first big hit game big winning opening opening time) is a prescribed number (10) of entering the big winning opening 33a and the execution of the winning ball payout associated therewith. The time when the possibility becomes extremely high, that is, the time when the prize ball payout amount increases, is preferably set to 25 seconds to 30 seconds, and is set to 26 seconds in this embodiment. The opening time of the big winning hole 33a for the second big hit game (the big winning hole opening time for the second big hit game) is a specified number (10) of the balls to the big winning hole 33a and the execution of the winning ball payout associated therewith. It is set as the time when the possibility becomes extremely low, that is, the time when the prize ball payout amount decreases (including the time when the prize ball payout amount becomes substantially zero), and is 0.1 second to 6 seconds In this embodiment, it is set to 0.2 seconds. Due to the difference in the opening times of these big winning openings 33a, the first big hit game is positioned as a “long term game” having a long execution period, and the second big hit game has a short execution period together with a small hit game which will be described later. It is positioned as a “winning game (specific hit game)”.

  In this embodiment, the number of rounds and the opening time of the big winning opening 33a are different between the first big hit game and the second big hit game, but the first big hit game and the second big hit game share the same number of rounds. And only the opening time of the special winning opening 33a may be different. For example, the number of rounds of the first jackpot game and the number of rounds of the second jackpot game are both 15 rounds, the opening time of the jackpot 33a in the first jackpot game is 26 seconds per round, and the big prize in the second jackpot game The opening time of the mouth 33a may be 0.1 seconds per round. Even in this case, the first big hit game has a long execution period (a lot of prize ball payout amount) “long-term game”, and the second big hit game has a short execution period (a little prize ball payout amount) “short term” "Per game (specific game)".

  Next, the small hit game will be described. When the first special symbol stopped and displayed by the first special symbol display unit 61 or the second special symbol stopped and displayed by the second special symbol display unit 62 is a small hit symbol (the result of the small hit determination is the small hit symbol) The main control unit 200 starts a small hit game. The small hit game is a hit game started by setting the small hit game flag to ON, and constitutes a “specific hit game” together with the second big hit game. In the small hit game, the big prize device 33 operates in the same manner as the second big hit game described above. In other words, in the small hit game, the large winning opening 33a is configured to be opened twice for 0.2 seconds, and the possibility that a game ball enters the large winning opening 33a is very low, so that the payout of the winning ball is substantially reduced. It is in a gaming state that does not accompany. It should be noted that, based on whether or not a prize ball is paid out in a winning game, “first big hit” is also referred to as “with a given ball”, and “second big hit” and “small hit” are also referred to as “without a given ball”. In addition, the “15R big hit symbol (15R probability variable big hit symbol, 15R normal big hit symbol)” that triggers the start of “15R big hit game (first big hit game)” corresponds to the “first special bonus symbol” of the present invention, The “2R big hit game (2R big hit game)” which is the start opportunity of the “2R big hit game” and the “small hit game” which is the start time of the “small hit game” are the “second hit game” of the present invention. It corresponds to “special design”.

  In the small hit game, since the operation of the second big hit game and the big prize device 33 is the same mode, the player can open and close the big winning opening 33a twice in a short time (a big winning opening opening pattern in the second big hit game) ) Cannot be discriminated whether the second big hit game or the small hit game has occurred. For this reason, it is more difficult to recognize whether or not the probability varying function is activated after the operation of the big winning device 33 (after the second big hit game or the small hit game is finished) (differentiation between the second big hit game and the small hit game). can do. Thus, the state in which the player has difficulty in recognizing (difficult to determine) that the probability variation function is operating is referred to as “probability non-notification state” or “latent probability variation state (internal probability variation state)”. Even when the number of rounds is the same for the first jackpot game and the second jackpot game, and only the opening time of the big prize opening 33a is different, the opening / closing pattern of the big prize opening 33a in the small prize game is the second. By making it the same as the big hit game, it is possible to make it difficult to distinguish the second big hit game from the small hit game. For example, if the opening time of the big winning opening 33a in the first big hit game is 26 seconds per round and the opening time of the big winning opening 33a in the second big hit game is 0.1 second per round, By making the number of times of opening of the big winning opening 33a 15 times and the opening time per time 0.1 seconds, it is possible to make it difficult to distinguish the second big hit game and the small hit game.

  As described above, the first jackpot game is a “long-term game” with a long execution period, and a predetermined number (10) of balls entered into the big winning opening 33a and the possibility of executing a prize ball payout associated therewith. It is extremely high, and it is positioned as a “game with every ball” that allows a large number of prize balls to be acquired. On the other hand, the specific hit game (second big hit game and small hit game) is a “short game per game” with a short execution period, and a specified number (10) of balls entered into the big winning opening 33a and a prize associated therewith. It is positioned as a “game without hitting a ball” where the possibility of ball payout is extremely low and it is difficult to obtain a large number of prize balls. In other words, the first big hit game is an advantageous game (high advantage) for the player, and the specific big game (the second big hit game and the small hit game) is disadvantageous for the player as compared to the first big hit game ( It is a per game with a low degree of advantage.

  In addition, “long-term games (first big hit games)” are hit games aimed at obtaining a large number of prize balls, whereas “short-term games (specific games per game)” is a game mode transition. Alternatively, it is a hit game for the purpose of maintaining the game mode. In other words, after the end of the 2R big hit game related to the second probability variable big hit, the probability variation function starts to operate for the gaming state at the start of the 2R big hit game (the game mode is shifted), and after the small hit game ends. The operating states of the probability changing function, the changing time shortening function, and the opening time extending function do not change with respect to the gaming state at the start of the small hit game (the gaming mode is maintained).

  In the present embodiment, the occurrence probabilities of “long term (first big hit)” and “short term (specific hit)” differ between the first special symbol success / failure determination and the second special symbol success / failure determination. Specifically, the second special symbol success / failure determination has a lower probability of “per short period (per specific)” and the occurrence of “per long term (first big hit)” than the first special symbol success / failure determination. The probability is high. That is, the probability that the first special symbol stops and displays with the specific hit symbol (2R probability variation big hit symbol, small hit symbol) is higher than the probability that the second special symbol stops with the specific hit symbol. The probability that the second special symbol stops and displays at the specific hit symbol may be set lower than the probability that the first special symbol stops and displays at the specific hit symbol. It is also possible to stop display with symbols).

  As mentioned above, “Short-term games (games per specific game)” hardly gives a prize ball. Therefore, “Long-term games” where a large number of award balls can be obtained are more suitable for players than short-term games. It will be advantageous. For this reason, the probability of occurrence per “short period (per specified)” is lower than the first special symbol success / failure determination, and the probability of occurrence per “long term (first big hit)” is higher than that of the first special symbol success / failure determination. The determination of whether or not the second special symbol is successful is more advantageous for the player, and the game ball is inserted into the second start port 28b than when the game ball is inserted into the first start port 28a and the game related to the first special symbol is performed. It is advantageous for the player to enter the ball and play the game according to the second special symbol.

  In the gaming machine of the present embodiment, after the big hit game is over, a privilege game (so-called time-short 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. The variable time shortening function, the opening time extending function, and the probability varying function operate by setting the fluctuation shortening flag, the opening extension flag, and the probability changing flag to ON, respectively. Note that the variable time shortening function and the open time extending function start and stop at the same time, and the short time game is performed by the operation of the variable time shortening function and the open time extending function. In the following description, when only one of the functions related to the operating state of the variable time shortening function and the open time extending function is described, the other function is also paired. For example, when it is described in the following description that “the variable time shortening function is operating”, this description can be interpreted as “the opening time extending function is also operating”. When it is described that “the function is operating”, this description can be understood as “the variable time reduction function is operating”. The fluctuation time shortening function, the open time extension function, and the probability fluctuation function are realized by the control of the main control unit 200.

  When the result of the first special symbol success / failure determination or the second special symbol success / failure determination is a big hit, after the big hit game is over, a variable time shortening function and an open time extending function for extending the opening time of the second start port 28b are provided. Operation may start. In this embodiment, when the type of big hit (initial hit) generated when the variable time shortening function and the open time extension function are not operated is “first big hit (15R positive variation big hit, 15R normal big hit)” When the first big hit game ends, the variable time shortening function and the open time extending function start to operate. In addition, when a big hit occurs when the variable time shortening function and the open time extending function are activated, the variable time shortening function and the open time extending function are started by ending the big hit game. The fluctuation time shortening function and the opening time extension function may be performed together when the probability variation function is operated together or when the probability variation function is not operated together. The fluctuation time reduction function includes a normal figure fluctuation time reduction function for reducing the fluctuation time of a normal symbol, and a special figure fluctuation time reduction function for reducing the fluctuation time of a special symbol (first special symbol and second special symbol). include. By the operation of the opening time extension function, the opening time of the second start port 28b is extended from the first opening time (for example, 0.2 seconds) to the second opening time (for example, 5 seconds). As a result, the frequency of entering the game ball into the second start port 28b is higher than that at normal time (when the opening extension function is not activated). Further, as described above, the normal symbol success / failure determination is performed in a high probability state (winning probability is “86/89”) in accordance with the operation of the variation time shortening function and the opening time extension function. During the operation period of the opening time extension function and the variable time reduction function, the number of fluctuations of the special symbol (the first special symbol and the second special symbol) until the next big hit game is started or after the big hit game is ended is a predetermined number of times. Set up to reach. The operation period of the open time extension function or the like (the number of times the special symbol has changed) is set using a fluctuation shortening counter. In this embodiment, “10,000” is set in the fluctuation shortening counter, and the operation period of the opening time extension function or the like is substantially started until the next big hit game is started. The fluctuation shortening counter is decremented by 1 every time the special symbol (the first special symbol and the second special symbol) is variably displayed. The fluctuation shortening counter corresponds to the “first counting means” of the present invention, and the value set in the fluctuation shortening counter corresponds to the “first predetermined value” of the present invention. Conditions for starting the opening time extension function and the fluctuating time reduction function after the end of the big hit game (starting conditions for the short time game) will be described later.

  In the present embodiment, a special variation period is provided after the big hit game ends. During the special variation period, the variation time for special variation (120 seconds) is set as the variation time of the normal symbol in preference to the variation time reduction function, and each of the first special symbol and the second special symbol is set. A variation pattern for special variation is set as the variation pattern, and special variation of the normal symbol, the first special symbol, and the second special symbol is performed. For this reason, in this embodiment, the variation shortening flag is set to ON at the end of the big hit game, but the shortening variation of the first special symbol, the second special symbol, and the normal symbol is performed after the elapse of the special variation period.

  During the special variation period, a “first big hit” occurs as the first hit, and starts with the end of the big hit game, and the total number of changes for each of the first special symbol and the second special symbol reaches a predetermined number. It ends when it does. The special variation period (total number of variations of each of the first special symbol and the second special symbol) is set using a special variation counter. In this embodiment, the special variation counter is set to any value of “500”, “200”, “100”, “70”, “50”, “30”, and the first special symbol or the second special symbol. Every time a symbol is displayed in a variable manner, 1 is subtracted. The special fluctuation period is set by setting the special fluctuation flag to ON when the special fluctuation counter exceeds zero. The special variation counter corresponds to the “second counting means” of the present invention, and the value set in the special variation counter corresponds to the “second predetermined value” of the present invention.

  In this embodiment, it is set so that the fluctuation shortening counter (operation period of the opening time extension function and the fluctuation time shortening function)> the special fluctuation counter (special fluctuation period). For this reason, when the special fluctuation counter becomes zero (when the special fluctuation period ends), the fluctuation reduction counter remains (fluctuation reduction counter> 0) and changes after the special fluctuation period ends (after the passage). The time-short game will be played until the abbreviated counter reaches zero or until the next big hit game is started. In other words, until the big hit game related to the “first big hit” as the first win is finished, the normal figure normal fluctuation game in which the normal symbol changes normally (normal time fluctuation: 30 seconds fluctuation in this embodiment) is performed, and the big hit Until the game ends and the special variation period elapses, the normal symbol special variation game is performed in which the normal symbol changes specially (long-term variation: 120 seconds variation in this embodiment), and changes after the special variation period elapses. Until the time shortening function is finished, a normal game short game is performed in which the normal symbol is shortened and changed (short-time change: 1 second change in this embodiment).

  Here, in a normal variation game where the opening time extension function does not operate, the variation time of the normal symbol is “30 seconds”, the probability of hitting the normal symbol is “2/89”, and the opening time of the second start port 28b Is set to “0.2 seconds”, while in the special figure variation game in which the opening time extension function is activated, the fluctuation time of the normal symbol is “120 seconds”, and the probability of hitting the normal symbol is “ 86/89 "and the opening time of the second start port 28b are set to" 5 seconds ", respectively. For this reason, in the special figure special variation game, the frequency that the fluctuation time of the normal symbol becomes longer and the result of the fluctuation display of the normal symbol is obtained compared with the normal variation normal game (frequency at which the winning symbol or the off symbol is stopped and displayed) However, the frequency at which the result of the normal symbol success / failure determination is hit is higher than that of the normal figure normal variation game, and the opening time of the second start port 28b when the result of the normal symbol success / failure determination becomes a hit is normal Since it is 10 times longer than the normal variation game, paying attention to the opening frequency (the number of times of opening, the opening time) of the second start port 28b, the special start game of the special variation game is more likely to be the second start port than the normal variation game. The opening frequency of 28b increases.

  In addition, in the short-time game with normal symbols, in which the opening time extension function is activated and the normal symbol is shortened, the normal symbol variation time is “1 second”, the normal symbol success / failure determination probability is “86/89”, 2 The opening time of the start port 28b is set to “5 seconds”, respectively. For this reason, in the normal game short game, the hit probability of the normal symbol success / failure determination and the opening time of the second start port 28b when the result of the normal symbol success / failure determination is a win are the same as those of the special symbol special variation game, Since the variation time of the normal symbol is shortened and the frequency of the normal symbol variation display result is obtained (frequency that the winning symbol or the off symbol is stopped and displayed) is higher than that of the special symbol special variation game, the second start port 28b. Focusing on the frequency of opening (number of times of opening, opening time), the opening frequency of the second start port 28b is higher in the normal time short game than in the normal special variable game.

  In view of the above, in this embodiment, the opening frequency of the second start port 28b increases in the order of normal map normal variable game <general map special variable game <normal map short game, and the three stages of the second start port 28b open. It is possible to create gaming states with different frequencies. In other words, the opening frequency of the second start port 28b is “minimum level” in the normal variation game, and the opening frequency of the second start port 28b is “intermediate level” in the special variation game. 2 The opening frequency of the start port 28b becomes the “highest level”. Further, in the present embodiment, the normal symbol normal variation game is performed with a normal symbol success / failure determination in a low probability state, and the normal symbol special variation game and the normal time short game are performed with a normal symbol success / failure determination in a high probability state. For this reason, the opening frequency of the second start port 28b can be effectively increased in the ordinary special variation game and the ordinary short-time game as compared with the ordinary normal variation game.

  Since the frequency of entering the game ball into the second start port 28b (the frequency with which the special symbol is held) is proportional to the frequency of opening the second start port 28b, it is normal that the second start port 28b has the lowest open frequency. In variable games, the number of second special symbols held is difficult to increase, and in the special special variable games in which the opening frequency of the second start port 28b is at an intermediate level, every time the variable time of the normal symbol elapses (this implementation In the example, every 120 seconds), the number of holdings of the second special symbol is likely to increase, and the number of holdings of the second special symbol is easy in the short-time game with the highest opening frequency of the second starting port 28b. The gaming state reaches the upper limit (four in this embodiment). That is, in the gaming machine 1 of the present embodiment, after the big hit game ends, when the opening frequency of the second start port 28b becomes an intermediate level and the special fluctuation counter becomes zero (the fluctuation shortening counter remains at this time). ) Has reached the so-called ceiling, and the opening frequency of the second start port 28b becomes the highest level.

  In this embodiment, after the big hit game (first big hit game) related to the “first big hit” as the first hit, the first special symbol or the first special symbol during the special fluctuation period until the counting by the special fluctuation counter is finished. When the 2nd special symbol is stopped and displayed with a specific hit symbol (2nd probable big hit symbol or small hit symbol), that is, when a "specific hit (second big hit or small hit)" occurs, special fluctuation at that time The counting by the counter is forcibly terminated, that is, the value of the special variation counter is forcibly set to zero, and the usual special variation game is forcibly terminated. In other words, the occurrence of a “specific hit (second big hit or small hit)” in a state where the special fluctuation counter and the fluctuation shortening counter are greater than zero causes the special fluctuation counter to finish counting (special fluctuation counter = 0) Counting by the fluctuation shortening counter continues. As a result, when a specific hit (second big hit or small hit) occurs during the execution of the special special variation game in which the opening frequency of the second start port 28b is “intermediate level”, the special fluctuation period is in the middle. When the game is finished and the opening frequency of the second start port 28b is “highest level”, the game immediately shifts to the short game at the normal time, so that the arrival at the ceiling is accelerated.

  Note that the above-described variation shortening counter and special variation counter are set, the processing for forcibly terminating the counting by the special variation counter (the processing for forcibly setting the value of the special variation counter to zero), the operation of the open time extension function, The main control unit 200 performs processing for shortening and changing the normal symbol and processing for specially changing the normal symbol. For this reason, the main control unit 200 of the present invention “first counting means”, “second counting means”, “second counting end means”, “opening time extension means”, “normal symbol normal variation means”, “normal It corresponds to “design special variation means” and “normal symbol shortening variation means”.

  If the result of the first special symbol success / failure determination or the second special symbol success / failure determination is a big hit, and the big hit type is “probable big hit”, in addition to the variable time reduction function and the open time extension function after the big hit game ends Thus, the probability variation function starts to operate and the probability variation game is started. The probability variation game is realized by the control of the main control unit 200. In this probability variation game, the probability that the result of the first special symbol success / failure determination and the second special symbol success / failure determination is a big hit, that is, the special symbol (first A probability variation function (special symbol probability variation means) that changes (improves) the probability that the special symbol and the second special symbol) stop display with the big hit symbol is activated.

  While the probability variation function is in operation, the probability that the jackpot value for the determination of success / failure increases increases the probability that the results of the first special symbol success / failure determination and the second special symbol success / failure determination will be a jackpot. Specifically, a normal probability success / failure determination table and a high probability success / failure determination table in which the number (type) of jackpot values is larger than the normal probability success / failure determination table are prepared. During normal games (when the probability variation function is inactive), the normal probability determination table is used to determine whether or not, and during probability change games (when the probability variation function is in operation), a high probability determination table is used. Make a pass / fail decision. In this embodiment, the maximum execution period of the probability variation game is set until the number of fluctuations of the special symbol after the big hit game reaches 10,000 times until the next big hit game is substantially started. .

  If the stop symbol of the first special symbol or the second special symbol is a specific hit symbol (second positive variation big hit symbol or small hit symbol), that is, if a specific hit (second big hit or small hit) occurs, the specific hit The operating state of the variable time shortening function and the open time extending function at the start of the game (when the second probability variation big hit symbol or small hit symbol is stopped and displayed) is maintained. In other words, if the fluctuation time reduction function and the release time extension function are activated at the start of the specific hit game, the fluctuation time reduction function and the release time extension function are activated even after the specific hit game ends (the time reduction game is started). ). On the other hand, if the fluctuation time shortening function and the opening time extension function are not activated at the start of the specific hit game, the fluctuation time shortening function and the opening time extension function are not activated even after the specific hit game is finished.

  Here, the progress of the game of the gaming machine 1 of the present embodiment will be briefly described. As described above, in the present embodiment, the first start port 28 a is provided at the lower center of the game area 21. For this reason, by performing “left-handed” (launching a game ball by so-called “bumming aim”) that launches a game ball toward the left region of the game region 21, the game ball is efficiently put into the first start port 28 a. You can enter. Further, the normal symbol operation gate 27 is provided at the upper right side of the game area 21, and the second start port 28 b is provided at the lower right side of the game area 21. For this reason, by performing “right-handed” to fire the game ball toward the right area of the game area 21, the game ball can be efficiently passed through the normal symbol operation gate 27, and the open state is achieved. A game ball can efficiently enter the second start port 28b.

  Then, in the normal figure normal variation game that is played before the big hit game is finished, the normal symbol usually fluctuates (in this example, the fluctuation time is 30 seconds), and the opening time of the second start port 28b is short (this time) In the embodiment, it is 0.2 seconds). In this case, since the opening interval of the second starting port 28b (normal symbol fluctuation time) is long and the opening time of the second starting port 28b is short, the game ball is not played even if the “right-handed” is performed. The possibility of entering the second starting port 28b is extremely low. For this reason, in the usual-type normally variable game, by performing “left-handed”, the game ball enters the first start port 28a located below the center of the game area 21, and the game related to the first special symbol is performed. This is advantageous (effective) for the player.

  Next, in the ordinary special variation game that is performed after the big hit game is finished until the special variation period elapses, the normal symbol has a special variation (the variation time is 120 seconds in this embodiment), and the second start port 28b. The opening time is long (5 seconds in this embodiment). In this case, although the opening time of the second start port 28b is longer than that of the normal normal variation game, the opening interval of the second start port 28b (normal symbol change time) is long. For this reason, even if the player hits the right side after recognizing that the second start port 28b has been opened, the fired game ball passes through the upper left side of the game area 21 and the right area of the game area 21. Since it takes time to reach the second starting port 28b located at the position, there is a possibility that the second starting port 28b may shift to the closed state during that time, and the game ball is effectively entered into the second starting port 28b. I can't let you. Particularly in this embodiment, since the second start port 28b is located at the lower right side of the game area 21, it takes a long time for the game ball to reach the second start port 28b, and the second start port 28b is closed. There is a high probability that it has transitioned to a state. For this reason, in the general-purpose special variation game, by performing “left-handed”, the game ball enters the first start port 28a located at the lower center of the game area 21, and the game related to the first special symbol is performed. This is advantageous (effective) for the player. Also, in this embodiment, by generating a specific win in the game related to the first special symbol during the special variation period, the special variation period (general special variation game) is forcibly terminated, and the normal-time-short game Migrate to For this reason, in the special-purpose special variation game, it is possible to shift to the short-time game at an early stage by performing “left-handed” and playing the game related to the first special symbol.

  Next, after the big hit game is over, in a normal game short game which is performed after the special variation period has elapsed, the normal symbol is shortened (in this embodiment, the variation time is 1 second), and the second start port 28b The opening time is long (5 seconds in this embodiment). In such a normal game, the opening time of the second starting port 28b is long, and the opening interval of the second starting port 28b (normal symbol variation time) is also short. By performing “right-handed”, the game ball can easily enter the second start port 28b. For this reason, in the short game at the normal time, by performing “right-handed”, the game ball enters the second start port 28b located in the right area of the game area 21, and the game related to the second special symbol is performed. However, this is advantageous (effective) for the player.

  As described above, in the gaming machine 1 according to the present embodiment, when a normal normal variation game and a special special variation game are performed, “left-handed” is performed in which a game ball is launched toward the left region of the game region 21. Thus, it becomes a “first special symbol variation gaming state” that makes it advantageous (effective) for the player to enter the gaming ball into the first starting port 28a. In addition, when a short game is performed in a normal time, it is necessary for the player to perform a “right hit” to fire a game ball toward the right area of the game area 21 and cause the game ball to enter the second start opening 28b. The “second special symbol variation gaming state” becomes advantageous (valid).

  If the result of the first special symbol success / failure determination or the second special symbol success / failure determination is a big hit, and the big hit type is “probable big hit”, in addition to the variable time reduction function and the open time extension function after the big hit game ends Thus, the probability variation function starts to operate and the probability variation game is started. The probability variation game is realized by the control of the main control unit 200. In this probability variation game, the probability that the result of the first special symbol success / failure determination and the second special symbol success / failure determination is a big hit, that is, the special symbol (first A probability variation function (special symbol probability variation means) that changes (improves) the probability that the special symbol and the second special symbol) stop display with the big hit symbol is activated.

  While the probability variation function is in operation, the probability that the jackpot value for the determination of success / failure increases increases the probability that the results of the first special symbol success / failure determination and the second special symbol success / failure determination will be a jackpot. Specifically, a normal probability success / failure determination table and a high probability success / failure determination table in which the number (type) of jackpot values is larger than the normal probability success / failure determination table are prepared. During normal games (when the probability variation function is inactive), the normal probability determination table is used to determine whether or not, and during probability change games (when the probability variation function is in operation), a high probability determination table is used. Make a pass / fail decision. In this embodiment, the maximum execution period of the probability variation game is set until the number of fluctuations of the special symbol after the big hit game reaches 10,000 times until the next big hit game is substantially started. .

  If the stop symbol of the first special symbol or the second special symbol is a specific hit symbol (second positive variation big hit symbol or small hit symbol), that is, if a specific hit (second big hit or small hit) occurs, the specific hit The operating state of the variable time shortening function and the open time extending function at the start of the game (when the second probability variation big hit symbol or small hit symbol is stopped and displayed) is maintained. In other words, if the fluctuation time reduction function and the release time extension function are activated at the start of the specific hit game, the fluctuation time reduction function and the release time extension function are activated even after the specific hit game ends (the time reduction game is started). ). On the other hand, if the fluctuation time shortening function and the opening time extension function are not activated at the start of the specific hit game, the fluctuation time shortening function and the opening time extension function are not activated even after the specific hit game is finished.

  In the gaming machine 1 according to the present embodiment, a symbol variation effect is provided on the effect display device 25 in association with the symbol variation game of the special symbol performed using the first special symbol display unit 61 or the second special symbol display unit 62. Done. As the symbol variation effect, for example, the effect symbol consisting of a number symbol is varied in conjunction with the variation display of the first special symbol on the first special symbol display unit 61 or the second special symbol display on the second special symbol display unit 62. Examples thereof include a variable display effect to be displayed and a reach effect performed during variable display of the effect symbol. Note that there are a plurality of types of effect contents, and effect image data is stored in the ROM of the effect display control unit 280.

  Here, the symbol variation effect realized under the control of the sub-control unit 260 and the effect display control unit 280 described later will be described. As shown in FIG. 2, in the display area of the effect display device 25, an effect symbol composed of numeric symbols is displayed. This effect symbol is displayed in conjunction with the change display and stop display of the first special symbol on the first special symbol display unit 61 or the second special symbol on the second special symbol display unit 62. Further, in the display area of the effect display device 25, the part excluding the display part of the effect symbol is a background display region in which various background symbols including characters, figures, symbols, characters, and the like are displayed. As described above, the effect display device 25 is arranged in the center of the game board 20 (game area 21), so that the player usually displays contents (particularly effect symbols) in the display area of the effect display device 25. The game will be played with attention.

  In this embodiment, a three-digit number symbol consisting of “1” to “9” is used as the effect symbol, and the display area of the effect symbol display device 25 is a right symbol display area in which the right symbol is displayed, and a middle symbol. Is composed of three symbol display areas including a middle symbol display area in which is displayed and a left symbol display area in which the left symbol is displayed. Each symbol display area has a symbol variation direction set in a direction substantially orthogonal to the arrangement direction of these display areas, in this case, in the vertical direction (vertical direction).

  The effect symbol starts to be changed when the first special symbol in the first special symbol display unit 61 or the second special symbol in the second special symbol display unit 62 starts to be changed, and the first special symbol or the second special symbol is displayed. Is stopped and displayed in any of the symbols, the effect symbol is stopped and displayed in a symbol corresponding to the stop symbol of the first special symbol or the second special symbol. As a result, the result of the first special symbol success / failure determination or the second special symbol success / failure determination (“big hit” or “off”) is notified by the effect symbol. In this embodiment, among the stop symbols of the production symbols, the combination of even symbols with the same three digits corresponds to the “normal jackpot symbol” with the special symbol, and the combination of odd symbols with the same three digits is the “first probability change” of the special symbol. Corresponding to the "hit symbol", such as an ordered combination such as "1, 2, 3", an odd numbered order such as "1, 3, 5", or an unreachable combination such as "7, 6, 7" Chance symbols (so-called chance eyes), which are predetermined specific off-call symbols other than the winning symbols, correspond to the special winning symbols (second probability variation big hit symbol, small hit symbol), and combinations of other symbols Corresponds to the special symbol "off symbol".

  The symbol variation effects such as the variation display effect and the reach effect of the effect symbols are a variation start command (variation pattern designation command and stop) transmitted from the main control unit 200 at the start of the variation display of the first special symbol or the second special symbol. It is configured to be performed under the control of the sub-control unit 260 based on the information specifying command). That is, the setting of the effect content performed in the symbol variation effect and the execution of the symbol variation effect are performed by the sub-control unit 260. Further, the effect contents (effect pattern) of the symbol variation effect are the first special symbol or the second special symbol determined when the result of the first special symbol success / failure determination or the second special symbol success / failure determination or the result of the success / failure determination is a big hit. 2. It is set at the start of the symbol variation effect based on the type of the big hit symbol of the special symbol.

  Here, the variation pattern designation command transmitted from the main control unit 200 to the sub-control unit 260 indicates the variation pattern of the first special symbol or the second special symbol, and specifically, the variation of the special symbol. Production contents such as time and presence / absence of reach production are shown. The main control unit 200 determines a variation pattern of the first special symbol or the second special symbol randomly (by random lottery) according to the result of the first special symbol success / failure determination or the second special symbol success / failure determination. Then, based on the variation pattern of the first special symbol or the second special symbol determined by the main control unit 200, the sub-control unit 260 produces the effect pattern (design variation effect) of the effect symbol displayed on the effect symbol display device 25. The production pattern) is determined. The stop information designation command transmitted from the main control unit 200 to the sub-control unit 260 indicates a special symbol stop symbol, and the main control unit 200 determines whether the first special symbol is appropriate or not. The stop symbol of the first special symbol or the second special symbol is determined at random (by random number lottery) according to the determination result. Then, based on the stop information designation command indicating the stop symbol of the first special symbol or the second special symbol determined by the main control unit 200, the sub-control unit 260 stops the display of the effect symbol displayed on the effect symbol display device 25. Determine the stop symbol.

  Next, the operation of the gaming machine 1 of this embodiment will be described based on a flowchart. FIG. 4 is an example of a main job performed under the control of the main control unit 200. The main job shown in FIG. 4 is executed by the CPU 200b mounted on the main control board 200a based on a program stored in a ROM (not shown) (an internal ROM of the CPU 200b or a ROM mounted on the main control board 200a). After the power-on process (S100), the game start process (S200), the normal symbol game process (S300), the ordinary electric game game process (S400), the special symbol game process (S500), and the winning game process (S600) Each process is repeatedly executed every time the timer is reset (in this embodiment, every 4 ms). The power-off generation process (S50) is a power-on process (S100) when a power failure occurs due to a power failure or the like, the used registers and stack pointers are saved, the payout motor is stopped, and a system reset occurs. It has come to move to.

  The power-on process (S100) is performed when the power is turned on and when power is restored after the power is cut off. When the power is turned on, RAM initialization processing is performed, and when the power is turned off, the game state is restored when the power is turned off. The return setting etc. for making it do is performed. Next, in the game start process (S200), detection of various switch states, update of various random numbers, prize ball payout control, and the like are performed.

  Next, the normal symbol game process (S300) will be described based on the flowchart of FIG. First, it is determined by the normal symbol operation gate detection switch 27s whether or not the game ball has passed the normal symbol operation gate 27 (S301). As a result, when it is determined that the game ball does not pass through the normal symbol operation gate 27 (S301: NO), the process proceeds to S304. On the other hand, when it is determined that the game ball has passed the normal symbol operation gate 27 (S301: YES), it is determined whether or not the normal symbol hold number is less than 4 (S302). As a result, when the number of normal symbols held is 4 or more (S302: NO), the process proceeds to S304. On the other hand, when the number of normal symbols held is less than 4 (S302: YES), a normal design success / failure random number is acquired and stored in a predetermined area of the RAM (S303). As a result, the number of normal symbol reservations increases by one.

  Next, it is determined whether or not the second start port 28b is open (S304). If it is determined that the second start port 28b is open (S304: YES), the normal symbol game process When it is determined that the second start port 28b is not open (S304: NO), it is determined whether or not the normal symbol is changing (S305). As a result, when it is determined that the normal symbol is changing (S305: YES), the process proceeds to S309. On the other hand, when it is determined that the normal symbol is not fluctuating (S305: NO), it is determined whether or not the normal symbol is in the stop display time (S306). Here, the stop display time of the normal symbol is a time for determining the normal symbol stopped and displayed. In this embodiment, the stop display time of the normal symbol is “1 second”. If it is determined that it is during the normal symbol stop display time (S306: NO), the process proceeds to S312 described later, and if it is determined that it is not during the normal symbol display time (S306: YES). ), It is determined whether or not the number of normal symbol hold is zero (S307).

  As a result, when it is determined that the number of normal symbol hold is zero (S307: YES), the normal symbol game process is terminated. On the other hand, when it is determined that the number of normal symbols held is not zero (S307: NO), normal symbol variation display related processing is performed (S308). Here, the normal symbol variation display related processing (S308) will be described based on the flowchart of FIG.

  First, the normal symbol success / failure random numbers acquired and stored in the process of S303 are read from a predetermined area of the RAM (S308a).

  Next, it is determined whether or not the fluctuation shortening flag is set to ON (whether or not the fluctuation time shortening function is operating) (S308b). As a result, if it is determined that the variation shortening flag is set to ON (the variation time shortening function is activated) (S308b: YES), the normal symbol success / failure determination is performed in a high probability state (S308c). . On the other hand, if it is determined that the variation shortening flag is not set to ON (the variation time shortening function is not activated) (S308b: NO), the normal symbol success / failure determination is performed in a low probability state (S308d). Since the setting states of the fluctuation shortening flag and the release extension flag are the same, the determination processing in S308b determines whether the release extension flag is set to ON instead of the fluctuation shortening flag (open time extension function). It may be determined whether or not is operating.

  Next, it is determined whether or not the determination result of the normal symbol success / failure determination performed in S308c or S308d is a win (S308e). As a result, when it is determined that the determination result of normal symbol win / fail determination is winning (S308e: YES), the winning symbol is set as a stop symbol of the normal symbol (S308f). On the other hand, when it is determined that the result of the normal symbol success / failure determination is not a hit (deletion) (S308e: NO), the out symbol is set as a stop symbol of the normal symbol (S308g).

  Next, it is determined whether or not the special fluctuation flag is set to ON (whether or not it is during the special fluctuation period) (S308h). The “special variation flag” is a flag indicating a special variation period, and is set to ON in the processing of S651 and S661 described later (see FIGS. 14 and 15).

  As a result of the determination process of S308h, when it is determined that the special variation flag is set to ON (during the special variation period) (S308h: YES), the variation time for special variation (normal variation time) In this embodiment, 120 seconds) is set (S308i). Thus, when the special fluctuation flag is set to ON, regardless of whether or not the opening time extension function and the fluctuation time reduction function are activated (even if the opening time extension function and the fluctuation time reduction function are in operation). Ordinarily, the symbols vary specially.

  On the other hand, as a result of the determination processing in S308h, if it is determined that the special variation flag is not set to ON (not in the special variation period) (S308h: NO), whether or not the variation reduction flag is set to ON. Is determined (S308j). As a result, when it is determined that the variation shortening flag is set to ON (S308j: YES), the variation time for shortening variation (1 second in this embodiment) is set as the variation time of the normal symbol (S308k). ). On the other hand, when it is determined that the fluctuation shortening flag is not set to ON (S308j: NO), the fluctuation time for normal fluctuation (30 seconds in this embodiment) is set as the fluctuation time of the normal symbol (S308l). .

  Next, the change of the normal symbol is started (S308m), and the normal symbol holding number is subtracted by 1 (S308n). The processing up to this point is to start the normal symbol variation display.

  Next, returning to FIG. 5, if it is determined in the process of S305 that the normal symbol is changing (S305: YES), it is determined whether or not the normal symbol change time has elapsed (S309). If it is determined that the normal symbol variation time has not elapsed (S309: NO), the normal symbol game process is terminated. On the other hand, if it is determined that the normal symbol variation time has elapsed (S309: YES), the normal symbol variation is stopped (S310), and the normal symbol stop display time is set (S311).

  Next, it is determined whether or not the normal symbol stop display time has elapsed (S312). If it is determined that the normal symbol stop display time has not elapsed (S312: NO), the normal symbol game processing is performed. Exit. On the other hand, when it is determined that the normal symbol stop display time has elapsed (S312: YES), the normal symbol stop symbol activates (opens) the second start port 28b. It is determined whether or not (S313). As a result, when it is determined that the stop symbol of the normal symbol is not a normal symbol (S313: NO), the normal symbol game process is terminated.

  On the other hand, when it is determined that the stop symbol of the normal symbol is a normal symbol (S313: YES), whether or not the release extension flag is set to ON (whether or not the release time extension function is activated). ) Is determined (S314). As a result, when the release extension flag is ON (when the release time extension function is activated) (S314: YES), a long-time release pattern (for example, 5 seconds) is set as the release pattern of the second start port 28b. If the release extension flag is OFF (when the release time extension function is not activated) (S314: NO), a short-time release pattern (for example, 0.2) is set as the release pattern of the second start port 28b. Second) is set (S316). Then, the operation of the second start port 28b is started (S317). As a result, the pair of blade pieces are opened left and right, and the second start port 28b is opened.

  Next, the ordinary electric accessory game process (S400) will be described based on the flowchart of FIG. First, it is determined whether or not the second start port 28b is operating (opening operation), that is, whether or not it is in an open state (S401). As a result, when it is determined that the second start port 28b is not in operation (is in a closed state) (S401: NO), the ordinary electric accessory game process is terminated. On the other hand, when it is determined that the second start port 28b is in operation (in an open state) (S401: YES), it is determined whether or not the operation time (open time) of the second start port 28b has elapsed. If it is determined (S402) and it is determined that the operating time of the second start port 28b has not elapsed (S402: NO), whether or not a predetermined number of winnings has been won at the second start port 28b (specified number) It is determined whether or not a game ball has entered (S403).

  As a result, when it is determined that there is no predetermined number of winnings in the second starting port 28b (S403: NO), the ordinary electric accessory game process is terminated. On the other hand, when it is determined that the predetermined number of winnings has been won at the second starting port 28b (S403: YES), and when it is determined that the operating time (opening time) of the second starting port 28b has elapsed. (S402: YES), the operation of the second start port 28b is stopped (S404). When the operation of the second start port 28b is stopped, the pair of blade pieces are closed, and the second start port 28b is in a closed state (normal state).

  Next, the special symbol game process (S500) will be described based on the flowcharts of FIGS. First, as shown in FIG. 8A, a start opening winning process is executed (S500). Here, the start opening winning process (S500) will be described based on the flowchart of FIG.

  First, it is determined whether or not the first start port 28a has been won (game ball has entered) based on the detection status of the first start port entrance detection switch 28s (S501a), and the first start port 28a has been won. If it is determined that there is not (S501a: NO). The process proceeds to S501d. On the other hand, if it is determined that the first start port 28a has been won (S501a: YES), it is determined whether or not the first special symbol hold number is less than 4 (S501b). As a result, when it is determined that the first special symbol reservation number is not less than 4 (4 or more) (S501b: NO), the process proceeds to S501d, and the first special symbol reservation number is less than 4. Is determined (S501b: YES), the first special symbol random number (first symbol success / failure determination information) is acquired and stored in a predetermined area of the RAM (S501c). The first special symbol random number includes a first special symbol determination random number, a first special symbol determination random number, a reach random number, and the like. Thereby, the 1st special symbol reservation number increases by one.

  Next, it is determined whether or not the second starting port 28b has been won based on the detection status of the second starting port ball detection switch 28t (S501d), and it is determined that the second starting port 28b has not been won. (S501d: NO). The start opening winning process is terminated. On the other hand, if it is determined that the second start port 28b has been won (S501d: YES), it is determined whether or not the second special symbol hold number is less than 4 (S501e). As a result, when it is determined that the second special symbol hold number is not less than 4 (4 or more) (S501e: NO), the start opening winning process is terminated, and the second special symbol hold number is less than 4. If it is determined that there is (S501e: YES), a second special symbol random number (second symbol success / failure determination information) is acquired and stored (S501f). 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.

  Next, returning to FIG. 8A, it is determined whether or not a winning game is being performed (whether the big hit game flag or the small hit game flag is ON) (S502). As a result, if it is determined that the game is a hit game (the big hit game flag or the small hit game flag is ON) (S502: YES), the special symbol game process is terminated, and the big hit game is not played (the big hit game) If it is determined that the flag and the small hit game flag are OFF) (S502: NO), it is determined whether or not the first special symbol or the second special symbol is changing (S503).

  As a result, when it is determined that the first special symbol or the second special symbol is fluctuating (S503: YES), the process proceeds to S510 described later, and the first special symbol or the second special symbol fluctuates. If it is determined that it is not in progress (S503: NO), it is determined whether or not it is during the stop display time of the first special symbol or the second special symbol (S504). Here, the stop display time of the special symbol is a time for determining the special symbol stopped and displayed. In this embodiment, the stop display time of the special symbol is “1 second”. And when it determines with it being during the stop display time of a 1st special symbol or a 2nd special symbol (S504: YES), it transfers to the process of below-mentioned S514, and is a 1st special symbol or a 2nd special symbol. When it is determined that it is not during the stop display time (S504: NO), it is determined whether or not the second special symbol hold 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 related process is performed (S508).

  On the other hand, if it is determined in the determination process of S506 that the second special symbol hold count is not zero (S506: NO), a second special symbol variation display related process is performed (S509). That is, if it is determined in the determination process of 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 Fluctuation display related processing of special symbols is executed. Thereby, the variation display of the second special symbol is performed in preference to the first special symbol, and the priority variation function of the second special symbol is realized by the determination processing in S506.

  Here, the first special symbol variation display related processing (S508) and the second special symbol variation display related processing (S509) will be described based on the flowcharts of FIGS. The first special symbol variation display related process and the second special symbol variation display related process are processes having the same contents except that the portions of the “first special symbol” and the “second special symbol” are different, respectively. The “special symbol” is “first special symbol” in the first special symbol variation display related processing, and “second special symbol” in the second special symbol variation display related processing. Here, the first special symbol variation table related indication processing (S508) will be described, and the description of the second special symbol variation display related processing (S509) will be omitted.

  First, a random number for determining whether or not a special symbol is stored in a predetermined area (first reserved storage area) of the RAM of the main control unit 200 (a random number for determining whether or not the game has entered the first starting port 28a) Is read (S508a).

  Next, it is determined whether or not the probability variation flag is set to ON (whether or not the probability variation function is activated) (S508b). As a result, when it is determined that the probability variation flag is set to ON (the probability variation function is activated) (S508b: YES), the first special symbol determination is performed in a high probability state (S508c). . On the other hand, if it is determined that the probability variation flag is not set to ON (the probability variation function is not activated) (S508b: NO), the first special symbol determination is performed in a low probability state (S508d).

  Next, it is determined whether or not the result of the first special symbol success / failure determination performed in S508c or S508d is a big hit (S508e). As a result, when it is determined that the result of the first special symbol success / failure determination is a big hit (S508e: YES), the variation pattern table of the first special symbol is set by the big hit hour variation pattern table distribution processing (S508f). ). On the other hand, when it is determined that the result of the first special symbol success / failure determination is not a big hit (is a loss) (S508e: NO), a small hit determination is performed (S508g).

  As a result, if it is determined that the game is a small hit (S508g: YES), the variation pattern table of the first special symbol is set by the small-patter variation pattern table distribution process (S508h). On the other hand, if it is determined that it is not a small hit (S508g: NO), it is a failure, so the variation pattern table of the first special symbol is set by the variation pattern table distribution process at the time of removal (S508i). The big hit time variation pattern table distribution processing (S508f), the small hit time variation pattern table distribution processing (S508h), and the loss variation pattern table distribution processing (S508h) have the same processing contents. Therefore, in the following, each variation pattern table distribution process will be described as a first special symbol variation pattern table distribution process (S550) based on FIG.

  As shown in FIG. 11, in the variation pattern table distribution process (S550) of the first special symbol, first, it is determined whether or not the special variation flag is set to ON (whether or not it is during the special variation period). (S551). As a result, when it is determined that the special variation flag is set to ON (during the special variation period) (S551: YES), the variation pattern table for special variation is set (S552). On the other hand, if it is determined that the special variation flag is not set to ON (not during the special variation period) (S551: NO), whether or not the probability variation flag is set to ON (the probability variation function is activated). Whether or not) is determined (S553).

  As a result, if it is determined that the probability variation flag is set to ON (the probability variation function is activated) (S553: YES), the probability variation pattern table is set (S554). On the other hand, when it is determined that the probability variation flag is not set to ON (the probability variation function is not activated) (S553: NO), whether or not the variation shortening flag is set to ON (variation time shortening). It is determined whether or not the function is operating (S555).

  As a result, when it is determined that the variation shortening flag is set to ON (the variation time shortening function is activated) (S555: YES), the time variation variation pattern table is set (S556). On the other hand, when it is determined that the variation shortening flag is not set to ON (the variation time shortening function is not activated) (S555: NO), the variation pattern table for normal variation is set (S557).

  As described above, the relationship of the length of the variation time of the special symbol defined by the variation pattern included in each variation pattern table is “(variation pattern for probability variation = variation pattern for time reduction) <variation pattern for special variation. <Normal variation pattern>.

  Next, returning to FIG. 10, when a variation pattern table corresponding to the current game mode is set by variation pattern table distribution processing, a variation pattern determination random number is acquired (S508j), and any one of S508f, S508h, and S508i is processed. The variation pattern corresponding to the variation pattern determination random number acquired in the process of S508j is selected from the variation patterns defined in the variation pattern table set in step S508, and the variation pattern in the variation display of the first special symbol starting from now is selected. Determine (S508k).

  Next, the design determination random number (the special symbol determination random number acquired when the game ball enters the first start port 28a) stored in a predetermined area of the RAM of the main control unit 200 is read (S508l), The stop symbol of the first special symbol to be stopped and displayed on the one special symbol display unit 61 is determined (S508m).

  Next, in accordance with the variation pattern determined in the process of S508k and the stop symbol determined in the process of S508m, the first special symbol display unit 61 starts the variation display of the first special symbol (S508n). Then, a variation pattern designation command for designating the variation pattern of the first special symbol and a special diagram stop information designation command for designating the stop symbol of the first special symbol are transmitted to the sub-control unit 260 (S508o), and the first special symbol is transmitted. The number of holdings is decremented by 1 (S508p). When the sub control unit 260 receives the variation pattern designation command and the special figure stop information designation command transmitted in the process of S508o, the sub control unit 260 starts the symbol variation effect (the variation display of the effect symbol) together with the effect display control unit 280. To do. The above is the processing when starting the variable display of the first special symbol.

  Next, returning to FIG. 8A, when it is determined in S503 that the first special symbol or the second special symbol is changing (S505: YES), the change display time of the changing special symbol is displayed. It is determined whether or not elapses (S510). 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 display of the special symbol is stopped (S511), a symbol stop command indicating that the variation display of the special symbol is stopped is transmitted to the sub-control unit 260 (S512), and the special symbol is displayed. The stop display time is set (S513).

  Next, it is determined whether or not the stop display time of the first special symbol or the second special symbol that has been stopped has elapsed (S514). As a result, when it is determined that the stop display time of the first special symbol or the second special symbol has not elapsed (S514: NO), the special symbol game process is terminated, and the first special symbol or the second special symbol is finished. When it is determined that the symbol stop display time has elapsed (S514: YES), the first special symbol or the second special symbol that is stopped and displayed on the first special symbol display unit 61 or the second special symbol display unit 62 is displayed. It is determined whether or not the special symbol stop symbol is a winning symbol (S515 in FIG. 8B).

  As a result, when it is determined that the stop symbol of the first special symbol or the second special symbol is a winning symbol (S515: YES), the current gaming state (the gaming state at the time of winning) is determined in a predetermined area of the RAM. (S516). The “current game state” includes the type of winning symbol stopped at that time and the setting state of the game state flag (probability change flag, change shortening flag, release extension flag, special change flag) at that point The values of various counters (variation shortening counter, special variation counter) are included.

  Next, it is determined whether or not the special variation flag is set to ON (S517). As a result, when it is determined that the special fluctuation flag is not set to ON (S517: NO), the process proceeds to S519 as it is. On the other hand, if it is determined that the special fluctuation flag is set to ON (S517: YES), the special fluctuation flag is set to OFF and the special fluctuation counter is set to “0” (S518). Transition to processing. Thereby, the special variation period ends with the start of the winning game. In this way, when the special variation flag is set to ON, that is, during the special variation period, the winning symbol of the first special symbol or the second special symbol is stopped and displayed when the winning symbol is stopped. When the type of the winning game is the first big hit game, the special fluctuation flag is set to ON and the special fluctuation counter is set at the end of the first big hit game by the processing of S661 and S662, which will be described later (FIG. 15). The value at the time of hitting is set, and the remaining period of the special fluctuation period is executed (resumption of the special fluctuation period). On the other hand, when the type of the winning game that is executed by the stop display of the winning symbol of the first special symbol or the second special symbol during the special variation period is a specific winning game, S661, which will be described later, at the end of the specific winning game. , S662 (FIG. 15) is not performed, and the special variation period is not started.

  Next, it is determined whether or not the winning symbol stopped and displayed on the first special symbol display unit 61 or the second special symbol display unit 62 is a small hit symbol (S519). As a result, when it is determined that the stop symbol displayed is not a small hit symbol (that is, a big hit symbol) (S519: NO), the stop symbol displayed is a 2R probability variable big hit symbol (No. 1). It is determined whether or not it is a two-probability big hit symbol) (S520). As a result, when it is determined that the winning symbol that is stopped and displayed is a 2R probability variation big winning symbol (S520: YES), the 2R big winning hole opening that is the opening pattern of the second big winning game big winning port 33a is opened. When the pattern is set (S521) and it is determined that the stop symbol displayed is not the 2R probability variation big hit symbol (if it is a 15R probability variation big hit symbol or a 15R normal big hit symbol) (S520: NO), the first big hit A 15R special winning opening opening pattern, which is an opening pattern of the special winning opening 33a for games, is set (S522). Then, the big hit game flag is set to ON (S523). Thereby, the big hit game is started according to the big winning opening opening pattern set in the processing of S521 or S522.

  Next, it is determined whether or not the probability variation flag is set to ON (S524). If it is determined that the probability variation flag is set to ON (S524: YES), the probability variation flag is set to OFF ( The process proceeds to S525) and S526. On the other hand, if it is determined that the probability variation flag is not set to ON (S524: NO), the process proceeds to S526 as it is.

  In the process of S526, it is determined whether or not the fluctuation shortening flag is set to ON. If it is determined that the fluctuation shortening flag is not set to ON (S526: NO), the special symbol game process is performed as it is. finish. On the other hand, when it is determined that the fluctuation shortening flag is set to ON (S526: YES), the fluctuation shortening flag is set to OFF and the fluctuation shortening counter is set to “0” (S527), and further released. The extension flag is set to OFF (S528). Thereby, with the start of the big hit game, the probability variation function, the variation time shortening function, and the open time extension function stop operating. The fluctuation shortening counter is for counting the operating period of the fluctuation time shortening function and the opening time extending function, and the processing of S655, S665, S673, and S674 described later is performed according to the type of jackpot at the end of the jackpot game. (See FIGS. 14 to 16).

  On the other hand, in the determination process of S519, when it is determined that the winning symbol stopped and displayed on the first special symbol display unit 61 or the second special symbol display unit 62 is a small symbol (S519: YES), The big winning opening opening pattern for small hits is set (S529). The small winning big winning opening opening pattern is an opening pattern of the small winning game big winning opening 33a, and is the same as the 2R big winning opening opening pattern set in the process of S521. Accordingly, when a game per short period (2R probability variation big hit game, small hit game) occurs, the opening / closing operation of the big prize opening 33a is performed in a common (identical) manner. It becomes difficult to identify (understand) whether “2R probability variation big hit” or “small hit” has occurred.

  Then, the small hit game flag is set to ON (S530). As a result, the small hit game is started in accordance with the small winning big opening opening pattern set in the process of S529.

  Next, it is determined whether or not the fluctuation shortening flag is set to ON (S531). As a result, if it is determined that the variation shortening flag is not set to ON (S531: NO), the special symbol game process is terminated, and if it is determined that the variation shortening flag is set to ON ( (S531: NO), "1" is subtracted from the fluctuation shortening counter (S532), and it is determined whether or not the fluctuation shortening counter has become "zero" (S533). When it is determined that the fluctuation shortening counter is not “zero” (S533: NO), the special symbol game process is terminated, and when it is determined that the fluctuation shortening counter is “zero” (S533). : YES), the fluctuation shortening flag is set to OFF (S527), and the release extension flag is set to OFF (S528). As a result, the fluctuation time shortening function and the open time extending function stop operating.

  Next, in the determination process of S515, the stop symbol of the first special symbol or the second special symbol stopped and displayed on the first special symbol display unit 61 or the second special symbol display unit 62 is not a winning symbol (in other words, If it is determined that it is an outlier symbol (S515: NO), it is determined whether or not the special variation flag is set to ON (whether or not it is during a special variation period) (S534).

  As a result, when it is determined that the special variation flag is not set to ON (not during the special variation period) (S534: NO), the process proceeds to S539. On the other hand, when it is determined that the special fluctuation flag is set to ON (during the special fluctuation period) (S534: YES), the special fluctuation counter is decremented by 1 (S535), and the special fluctuation counter becomes zero. It is determined whether or not (S536).

  As a result, when it is determined that the special variation counter is not zero (S536: NO), the process proceeds to S539. On the other hand, when it is determined that the special fluctuation counter has become zero (S536: YES), the special fluctuation flag is set to OFF (S537). Thereby, the special variation period ends. Then, a gaming state designation command indicating the current gaming state is transmitted to the sub-control unit 260 (S538). The gaming state designation command is a command for designating a symbol variation state (special variation, shortening variation, normal variation) based on the state of the gaming state flag (special variation flag, probability variation flag, variation shortening flag, release extension flag). . Here, a gaming state designation command indicating that the special variation period has ended is transmitted. Then, the sub-control unit 260 (CPU 260b) performs a state notification effect indicating the current gaming state based on the gaming state designation command transmitted from the main control unit 200. As the state notification effect, in the background display area of the display screen of the effect display device 25, the current game state (game mode) is shown using characters, figures, symbols, characters, changes in display color (background color), and the like. For example, the effect display can be performed.

  As described above, the execution period of the special variation period is defined by the number of executions of the special symbol (first special symbol, second special symbol) variable display (the special symbol variable display frequency). In addition, if the variation time based on the variation pattern (variation pattern for special variation) of the special symbol (the first special symbol, the second special symbol) during the special variation period is long, the execution period of the special variation period becomes longer. On the contrary, if it is shorter, the execution period of the special variation period becomes longer. That is, the length of the execution period of the special variation period depends on the number of executions of the variable display of the special symbol (the first special symbol and the second special symbol) and the variable display time. In the present embodiment, using the execution period of such special variation, the effect display device 25 is in a gaming state (game mode) in which the opening frequency of the second start port 28b is “intermediate level”. The state notification effect shown is performed.

  Next, returning to FIG. 8B, it is determined whether or not the fluctuation shortening flag is set to ON (S539). As a result, if it is determined that the variation shortening flag is not set to ON (S539: NO), the special symbol game process is terminated, and if it is determined that the variation shortening flag is set to ON ( S539: YES), the fluctuation shortening counter is decremented by 1 (S540), and it is determined whether or not the fluctuation shortening counter has become zero (S541).

  If it is determined that the fluctuation shortening counter is not zero (S541: NO), the special symbol game process is terminated, and if it is determined that the fluctuation shortening counter is zero (S541: YES). ), The fluctuation shortening flag is turned off (S542), and the open extension flag is turned off (S543). As a result, the variable time shortening function and the open time extending function are deactivated. Then, the gaming state designation command is transmitted to the sub-control unit 260 (S544). Here, the game time designation command indicating that the change time shortening function and the open time extension function are deactivated and the transition from the shortened change state to the normal change state is transmitted.

  Next, the winning game process (S600) will be described based on the flowchart of FIG. First, it is determined whether or not a hit game is being performed (whether the big hit game flag or the small hit game flag is set to ON) (S601). As a result, when it is determined that the winning game is not being played (the big hit game flag and the small hit game flag are set to OFF) (S601: NO), the winning game process is terminated and the winning game is being played ( If it is determined that the big hit game flag or the small hit game flag is set to ON (S601: YES), it is determined whether or not the big 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. When it is determined that the opening time has not elapsed (S603: NO), it is determined whether or not the specified winning number 33a has been won (whether or not the specified number of game balls have entered). (S604). In the present embodiment, it is determined whether or not ten game balls have entered the special winning opening 33a.

  As a result, when it is determined that the prescribed number of winnings has not been won in the big winning opening 33a (S604: NO), the winning game process is terminated and the prescribed winning number has been won in the big winning opening 33a. When it is determined (S604: YES) or when 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 a winning game end condition is satisfied (S606). In the determination process of S606, if the hit game currently being executed is the first big hit game, it is determined whether or not the number of rounds of the big hit game has reached 15 rounds, and the currently executed hit game is the second big hit game. If it is, it is determined whether or not the number of rounds of the big hit game has reached two rounds. If the hit game currently being executed is a small hit game, has the number of times of opening the big prize winning opening 33a been reached? Determine whether or not.

  As a result, when it is determined that the winning game end condition is not satisfied (S606: NO), it is determined whether or not the closing time (interval time) of the special 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 winning game process is terminated and it is determined that the closing time of the special winning opening 33a has elapsed. (S607: YES), the special winning opening 33a is opened (S608).

  When it is determined in S606 that the winning game end condition is satisfied (S606: YES), a winning game end process is performed (S610). Here, the winning game end process (S610) will be described based on the flowchart of FIG.

  In the winning game end process (S610), first, the winning game flag (big hit game flag or small hit game flag) is set to OFF (S610a). As a result, the winning game ends.

  Next, whether or not the current hit is a probable big hit (15R probable big hit or 2R probable big hit) (whether the stop symbol of the special symbol that triggered this hit game is a probable big hit symbol) Determine (S610b). As a result, when it is determined that the probability variation is a big hit (S610b: YES), the probability variation flag is set to ON (S610c). Thereby, with the end of the big hit game related to the current probability big hit, the probability variation function starts to operate (becomes a high probability state). On the other hand, when it is determined that the current hit is not a probable big hit (S610b: NO), the type of the current hit is a normal big hit (15R normal big hit), so the probability change flag is not set to ON. , The process proceeds to S610d.

  Next, the value of the fluctuation shortening counter at the time of hit occurrence stored in the predetermined area of the RAM in the process of S516 is read, and whether or not the value of the fluctuation shortening counter at the time of hit occurrence has exceeded “0” (fluctuation time). It is determined whether or not the shortening function and the open time extending function have been activated (S610d). As a result, when it is determined that the value of the fluctuation shortening counter at the time of hitting does not exceed “0” (the fluctuation time shortening function and the open time extending function are not activated) (S610d: NO), this time The winning game that has been completed is triggered by the occurrence of a hit in the state (normal fluctuation period) in which the usual normal fluctuation game with the lowest opening frequency of the second start port 28b is being performed, that is, the occurrence of the “first win”. Therefore, the first hit end setting process is executed (S610e). Here, the initial hit end setting process (S610e) will be described based on the flowchart of FIG.

  First, whether or not the type of the current hit is a specific hit (second big hit or small hit) (the stop symbol of the special symbol that triggered the start of the current hit game is a 2R probability variable big hit symbol or a small hit symbol) (S650). As a result, when it is determined that the type of hit this time is a specific hit (second big hit or small hit) (S650: YES), the variable time reduction function and the open time extension function are set. Instead, the initial hit end setting process is terminated. Thereby, the operating state of the fluctuation time shortening function and the open time extending function when the specific hit occurs can be maintained.

  On the other hand, if it is determined that the current hit type is not a specific hit (not the second big hit or the small hit) (S650: NO), the current hit type is the first big hit, so there is a special variation. The flag is set to ON (S651), and a predetermined value N is set to the special variation counter (S652). Thereby, the period until the total number of changes of the first special symbol and the second special symbol after the end of the first big hit game (15R big hit game) reaches N times is set as the special fluctuation period. As described above, any value selected from “500”, “200”, “100”, “70”, “50”, and “30” is set in “predetermined value N”.

  Next, the fluctuation shortening flag is set to ON (S653), the open extension flag is set to ON (S654), and "10,000" is set to the fluctuation shortening counter (S655). Thereby, after the end of the first big hit game, the variable time shortening function and the open time extending function start to operate.

  Next, returning to FIG. 13, it is determined in the determination processing in S610d that the value of the fluctuation shortening counter at the time of occurrence of hit exceeds “0” (the fluctuation time shortening function and the open time extending function were activated). If it is detected (S610d: YES), it is determined whether or not the value of the special variation counter at the time of occurrence of the hit exceeds “0” (whether or not it was during the special variation period) (S610f). As a result, when it is determined that the value of the special fluctuation counter at the time of hitting has exceeded “0” (during the special fluctuation period) (S610f: YES), the winning game that has ended this time is 2 Since the occurrence of a hit in a state in which a special special variable game with an intermediate level of opening of the start port 28b is being performed (special change period), that is, the occurrence of “a hit before reaching the ceiling”, the ceiling has been reached. A front end setting process is executed (S610g). Here, the finish setting process before reaching the ceiling (S610g) will be described based on the flowchart of FIG.

  First, whether or not the type of the current hit is a specific hit (second big hit or small hit) (the stop symbol of the special symbol that triggered the start of the current hit game is a 2R probability variable big hit symbol or a small hit symbol) Whether or not) is determined (S660). As a result, if it is determined that the current hit type is not a specific hit (second big hit or small hit) (S660: NO), the current hit type is the first big hit, The fluctuation flag is set to ON (S661), and the value of the special fluctuation counter at the time of hit occurrence stored in the predetermined area of the RAM in the process of S516 is read, and the read value is set in the special fluctuation counter (S662). ). Thus, when the first big hit occurs during the special fluctuation period, the remaining period of the special fluctuation period at the time of occurrence is executed after the end of the first big hit game.

  On the other hand, when it is determined that the hit type of this time is a specific hit (second big hit or small hit) (S660: YES), S663 is set without setting the special fluctuation flag or special fluctuation counter. Move on to processing. As a result, if a special hit occurs during a special variation period, even if there is a remaining period of the special variation period at the time of occurrence, the special variation period (ordinary special variation game) is forced Will be terminated.

  Next, the fluctuation shortening flag is set to ON (S663), the open extension flag is set to ON (S664), and "10,000" is set to the fluctuation shortening counter (S665). As a result, the fluctuation time shortening function and the opening time extension function start to operate, and when the processes of S663 to S665 are performed through the above-described processes of S661 and S662, the special fluctuation period (ordinary special fluctuation game) ) Will end immediately regardless of the remaining period, and will shift to a short game at normal times.

  Next, returning to FIG. 13, when it is determined in the determination processing in S610f that the value of the special variation counter at the time of occurrence of the hit does not exceed “0” (not in the special variation period) (S610f: NO). The hit game that has been completed this time is the period when the special variation period ends, and the occurrence of a hit in the state where the short-time game at the normal time with the highest opening frequency of the second start port 28b is being performed (shortened variation period), that is, “ceiling” Since the occurrence of “hit after reaching” is triggered, the end setting process for hitting after reaching the ceiling is executed (S610h). Here, the hit end setting process (S610h) after reaching the ceiling will be described based on the flowchart of FIG.

  First, the fluctuation shortening flag and the release extension flag are respectively set to ON (S670, S671), and whether or not the type of the current hit is a probable big hit (the stop symbol of the special symbol that triggered the start of the current hit game) Whether or not is a probable big hit symbol) is determined (S672). As a result, when it is determined that the current hit type is a probable big hit (S672: YES), "10,000" is set in the fluctuation shortening counter (S673). Thereby, after the end of the current winning game, the variable time shortening function and the open time extending function are operated until the next big hit occurs. On the other hand, if it is determined that the current hit type is not a probabilistic big hit (S672: NO), the current hit type is a normal big hit (15R normal big hit), so the variation shortening counter is “100”. Is set (S674). As a result, after the end of the current winning game, until the total number of fluctuations of the first special symbol and the second special symbol reaches 100 times, or until the next big hit occurs before the number of times reaches 100 times, The variable time shortening function and the open time extending function start operation.

  When the processing for setting various flags and counters (S610e, S610g, S610h) is completed as described above, a gaming state designation command is transmitted to the sub-control unit 260 as shown in FIG. 13 (S610i). Here, a gaming state designation command indicating a gaming state corresponding to various flags and counter setting states that can be set by any of the above-described processes of S610c, S610e, S610g, and S610h is transmitted.

  Here, the correspondence between the processing shown in the flowcharts of FIGS. 5 to 16 and each means of the present invention will be described. The processing of “S301 to S307, S308e to S308m, S309, and S310 (FIGS. 5 and 6). ) "Corresponds to the normal symbol display control means, and" S501 to S507, S508e to S508n, S509e to S509n, S510, S511 processing (FIGS. 8A, 9, and 10) "is the special symbol display control means. “S601 to S608 (FIG. 12)” corresponds to the hit game execution means, and “S532, S533, S540, S541, S655, S665, S673, S674 (FIG. 8B, FIG. 14 to 16) ”corresponds to the first counting means, and“ the processing of S535, S536, S652, and S662 (FIG. 8B, FIG. 14, FIG. 15) ”is the second counting. Corresponding to the stage, "S314, S315, S654, S664, S671" (FIGS. 5, 14 to 16) "corresponds to the open time extension means, and" S308l processing (FIG. 6) "is the normal symbol normal Corresponding to the changing means, “S308i processing (FIG. 6)” corresponds to the normal symbol special changing means, “S308k processing (FIG. 6)” corresponds to the normal symbol shortening changing means, “S610f: YES, S610g”. , S660: YES processing (FIGS. 13 and 15) ”corresponds to the second counting end means.

  In the present embodiment described above, the opening frequency of the second start port 28b is at the lowest level until the first big hit game (15R big hit game) related to the first big hit (15R big hit) as the so-called "first hit" ends. A normal variation game (normal variation period) is performed, and a special variation game (special variation period) in which the opening frequency of the second start port 28b is intermediate is performed at the end of the first big hit game After the special variation period, a normal game short game (shortened variation period) in which the opening frequency of the second start port 28b is the highest level is performed. As described above, by providing the special variation period in which the special variation of the normal symbol is performed after the end of the first big hit game (15R big hit game), it is possible to create a three-stage gaming state in which the opening frequency of the second start port 28b is different. When the first jackpot game (15R jackpot game) ends, the opening frequency of the second start port 28b improves (becomes an intermediate level), and when the special fluctuation period ends, the so-called ceiling is reached, and the second It is possible to provide a new game characteristic that the opening frequency of the start port 28b becomes the highest level, and to improve the game entertainment.

  Further, in this embodiment, the normal symbol operating gate 27 is arranged at the upper right side of the gaming area 21, the first starting port 28 a is arranged at the lower center of the gaming area 21, and the second starting port 28 b is arranged at the right side of the gaming area 21. Located at the bottom. As a result, the game period until the first big hit game as the “first win” is ended, that is, “the normal variable game is performed”, and the special fluctuation period elapses after the first big hit game is ended. The game period until the game is completed, that is, the “period in which the special-purpose special variable game is performed” is performed “left-handed” in which the game ball is launched toward the left region of the game region 21, and the game ball is moved to the first start port 28a. It becomes the “first special symbol variation gaming state” in which it is advantageous for the player to enter the ball. In addition, a game period until the special variation period elapses, that is, a “period in which a normal game is performed at a short time” is “right-handed” in which a game ball is launched toward the right area of the game area 21, and the game ball It becomes the “second special symbol variation gaming state” in which it is advantageous for the player to enter the ball into the second starting port 28b. As a result, until the short game at the normal time starts (until the ceiling is reached), the game proceeds with “left-handed”, and the short game at the normal time starts (has reached the ceiling) It is possible to provide a new gameability of starting “right-handed”, thereby improving the game entertainment.

  Further, in this embodiment, when a specific hit (second big hit or small hit) occurs during a special fluctuation period in which the special fluctuation game with the usual opening rate of the second start port 28b is set to “intermediate level”. Even if there is a remaining period in the special variation period at that time, the special variation period (ordinary special variation game) will not be resumed after the end of the specific hit game (2R big hit game or small hit game) The special variation game is forced to end and the short game is started. For example, when the first big hit game executed at the first first big hit is completed, “200” is set in the special fluctuation counter and the special fluctuation counter becomes “100” (in the special fluctuation period). If a specific hit occurs when the total number of fluctuations of the first special symbol and the second special symbol reaches 100 after the start), “100” set in the special fluctuation counter at that time is specified. After the winning game is over, it is not taken over, and the value of the special variation counter becomes zero. After the specific winning game is finished, the normal time short game is started.

  In this way, in this embodiment, if a specific hit occurs during the special fluctuation period (in the special figure special fluctuation game), the special fluctuation period (general figure special fluctuation game) will occur before reaching the ceiling. When the second start port 28b is opened at the “highest level”, the game immediately shifts to the normal game. As a result, during the special fluctuation period after the first big hit game is over, a special hit (second big hit or small hit) is generated depending on the timing (a timing when the special symbol is stopped and displayed with the special symbol per second). The time to shift from the variable period (general special variation game) to the short-time game at the normal time will be different, and it is possible to provide a new game with a variety of periods until the transition to the short-time game at the normal time. Interest can be improved.

  Further, in the present embodiment, the specific hit game (2R big hit game, small hit game) is configured as a hit game that has a smaller number of winning balls than the first big hit game and is disadvantageous to the player. With the execution of a specific per game (occurrence per specific) as a trigger, the player shifts from the special variation period (ordinary special variation game) to the short game at the normal time immediately (before reaching the ceiling). The occurrence of a specific hit (second big hit or small hit) is expected in the special fluctuation period (ordinary special fluctuation game). Thereby, a meaning can be given with respect to specific hits, and a game entertainment interest can be improved.

  In this embodiment, a first special symbol corresponding to the first starting port 28a (fixed starting port) and a second special symbol corresponding to the second starting port 28b (variable starting port) are provided, and the second special symbol is provided. The game according to the first special symbol has a higher probability per occurrence than the game according to the symbol. As a result, the game related to the first special symbol is performed by “left-handed” as compared to the case where the game related to the second special symbol is performed by “right-handed” (the game is advanced in the second special symbol variable game state). In the case (promoting the game in the first special symbol variation game state), it is easier to forcibly end the special variation period (common figure special variation game) in a short period (end before reaching the ceiling). Can be realized. Furthermore, if the game related to the second special symbol (the second special symbol variable game state) does not generate a specific win and only the game related to the first special symbol occurs, the first special symbol is included. Only in such a game (the first special symbol variation game state), the game characteristic that the special variation period (ordinary special variation game) can be forcibly terminated (terminated before reaching the ceiling) can be realized.

  In the present embodiment, since the special symbol variation time (120 seconds) is set to be longer than the normal variation variation time (30 seconds), the opening frequency of the second start port 28b is set to be low. Three different levels (lowest level, intermediate level, highest level) can be created effectively. In particular, at the intermediate level, the opening time of the second start port 28b is equivalent to the maximum level, but since the fluctuation display time of the normal symbol is longer than the maximum level, the frequency at which the second start port 28b is opened. The (number of times) is lower than the maximum level, and the frequency of entering the game ball into the second start port 28b does not become as high as the maximum level. Further, at the intermediate level, although the fluctuation display time of the normal symbol is longer than the minimum level, the opening time of the second start port 28b is longer than the minimum level, so the frequency at which the second start port 28b is in the open state. The (number of times) is higher than the lowest level, and the frequency of entering the game ball into the second start port 28b is higher than the lowest level. Thus, in the present embodiment, the difference between each of the three stages (the lowest level, the intermediate level, and the highest level) with different opening frequencies of the second start port 28b can be clarified for the player. Then, after the start of the special variation period, the player can easily recognize the change related to the normal symbol variation display, and can easily recognize the change in the opening state of the second start port 28b. It is possible to effectively impress the player that the game has shifted from the normal variation game to the normal special variation game.

  Further, according to the configuration of the present embodiment, the special variation counter is set at the end of the first first big hit game, and thereafter, the game related to the first special symbol and the second special symbol (special symbol game) proceeds. At the same time, the value of the special variation counter gradually decreases. When the first big hit occurs in the middle of the special fluctuation period (special fluctuation counter> “0” state), when the first big hit game executed by the occurrence of the first big hit is ended. The value of the previous special fluctuation counter is inherited. For example, when the first big hit game executed at the first first big hit is completed, “200” is set in the special fluctuation counter and the special fluctuation counter becomes “100” (in the special fluctuation period). When the first big hit occurs for the second time when the number of fluctuations of the special symbol reaches 100 after the start, “100” is set in the special fluctuation counter at the end of the second first big hit game. The second special variation period starts in the state.

  And after the start of the second special variation period, when the total variation display count of the first special symbol and the second special symbol reaches 100 times, the big variation does not occur and the special variation counter becomes zero The special variation period ends (so-called ceiling is reached), the normal symbol shortening variation starts, and the opening frequency of the second start port 28b reaches the highest level. After that (after reaching the ceiling), if the third big hit (first big hit or second big hit) occurs, the special fluctuation counter is not set at the end of the third big hit game, and the special fluctuation period is not set ( Special fluctuation counter = “0”, fluctuation shortening counter = “10,000”). For this reason, the normal symbol shortening variation is started immediately after the end of the big hit game without the special symbol special variation.

  In this way, by taking over the value of the previous special variation counter, at the end of the first big hit game after the second time, the special variation period is started with a small value (or zero) in the special variation counter. As a result, after the first big hit game for the first win is over, even if the first big hit occurs again due to the progress of the special symbol game, the special variation period will not be newly set, so it was set first. The special variable period will not be extended on the way. As a result, after the end of the first big hit game for the first hit, as long as the special symbol game is advanced, it will always approach the ceiling (the end of the special variable period), so by reaching the ceiling (the end of the special variable period) Many players can experience the gameability that the opening frequency of the second start port 28b becomes the highest level.

(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 above embodiment, the second start port 28b is arranged at the lower right side of the game area 21, but the second start port 28b is at the upper right side of the game area 21 as shown in FIG. You may arrange | position just under 27. As described above, when the second start port 28b is arranged at the upper right side of the game area 21 (below the normal symbol operating gate 27), it is compared with the case where the second start port 28b is arranged at the lower right side of the game area 21. Thus, the time required for the launched game ball to reach the second start port 28b via the upper left portion of the game area 21 is shortened. For this reason, when “right-handed” is performed in a special variation period (ordinary special variation game), the game ball passes to the normal symbol operation gate 27 and the game to the second start port 28b that is in the open state. Sphere entry is generated more efficiently. As a result, in the game progression process in the special variation period (general special variation game), by performing “right-handed” in addition to “left-handed”, the special variation period in which the game related to the first special symbol is the main A state in which a game related to the second special symbol is performed can be temporarily generated. As a result, the “first special symbol variable game state (normal game normal variable game)” in which a game ball is inserted into the first starting port 28 a by “left-handed” and a game related to the first special symbol is performed, and “right-handed normal game” "Left-handed" and "Left-handed" between "Second special symbol variation gaming state (short game at normal time)" in which a game ball is inserted into the second starting port 28b and a game related to the second special symbol is performed. “Right-handed” selectively selects a game related to the first special symbol based on the game ball entering the first starting port 28a and a game related to the second special symbol based on the game ball entering the second starting port 28b. It is possible to create an intermediate stage gaming state (mixed gaming state).

  In the above embodiment, the normal symbol success / failure determination is performed in a low probability state when the open time extension function is not operated, and the normal symbol success / failure determination is performed in a high probability state when the release time extension function is operated. The present invention is not limited to this, and can also be applied to a gaming machine in which the winning probability of normal symbol determination is set to be constant. In this case, the winning probability of the normal symbol success / failure determination adopts the winning probability of the normal symbol success / failure determination in the high probability state among the low probability state and the high probability state described in the above embodiment as a constant winning probability. Is preferred. That is, the winning probability of the normal symbol success / failure determination when the open time extension function is not activated and activated can be set to “86/89”.

  However, in this case, it is necessary to set the fluctuation time of the normal symbol in the normal normal fluctuation game when the opening time extension function is inactive to a long time such as “180 seconds”. In this way, in the normal figure normal variation game, even if the winning probability of the normal symbol success / failure determination is high, the frequency of the normal symbol variation display result (frequency that the winning symbol or the off symbol is stopped and displayed) is low, Since the opening time of the second starting port 28b is also set to a short time (for example, 0.2 seconds), as a result, the opening frequency of the second starting port 28b can be lowered (minimum level).

  Then, in the special special variation game in which the opening frequency of the second start port 28b is “intermediate level” higher than that in the normal variation game, the normal symbol variation time is set to the same time as the normal variation game (for example, 180). Second) or shorter than the normal game, and longer than the normal game (for example, 120 seconds), and the opening time of the second start port 28b is set to a long time (for example, 5 seconds). Thus, the opening frequency of the second start port 28b can be set to an “intermediate level” higher than that of the normal variation game. Also, in a normal time short game where the opening frequency of the second start port 28b is "highest level" higher than that of a special special variation game, the normal symbol change time is set to the same time as the normal time short game of the above embodiment ( For example, 1 second), and the opening time of the second starting port 28b is set to a long time (for example, 5 seconds), so that the opening frequency of the second starting port 28b is set to the “highest level” higher than the usual special variation game. be able to. As a result, even when the winning probability of the normal symbol success / failure determination is constant, the opening frequency of the second start port 28b can be varied in three stages (the lowest level, the intermediate level, and the highest level).

  In the above embodiment, the variation shortening counter and the special variation counter are configured to be set at the end of the big hit game. However, the present invention is not limited to this. You may comprise so that a fluctuation | variation counter may be set.

  In the above embodiment, the special symbol variation time (120 seconds) is set longer than the normal variation variation time (30 seconds). However, the present invention is not limited to this. The time may be set to be equal to or longer than the normal fluctuation time.

  In the above embodiment, the fluctuation shortening counter is set to “10,000” and the open time extending function or the like is operated until the next big hit game is substantially started. The fluctuation shortening counter is larger than the value set in the special fluctuation counter (in the above embodiment, any one of “500”, “200”, “100”, “70”, “50”, “30”). If there is, it is not necessary to set “10,000”. In particular, in the configuration in which the value of the special variation counter is inherited as in the above-described embodiment, when the special variation counter becomes zero, if the variation shortening counter is set to “10,000”, the open time extension function or the like will be extended. Therefore, it is desirable to set a value (for example, “100”) smaller than “10,000” to the fluctuation shortening counter when at least the special fluctuation counter becomes zero.

  Further, in the above embodiment, each time the variation display of the first special symbol and the second special symbol is performed once, a predetermined value is set in each of the variation shortening counter and the special variation counter at the end of the big hit game. Each counter is decremented by 1, and the operation (counting) of each counter is terminated when the value of each counter becomes zero. However, the counter is not limited to such a subtraction type counter. An expression counter may be used. That is, an upper limit value counted (counted) by the variation shortening counter and an upper limit value counted (counted) by the special variation counter are determined in advance (for example, “10,000” for the variation shortening counter and “500” for the special variation counter). , “200”, “100”, “70”, “50”, “30”), after the end of the big hit game, start the operation (counting) of the variation shortening counter and the special variation counter, Each time each variable display of the special symbol and the second special symbol is performed once, each counter is incremented by one, and when the value of each counter reaches the above-mentioned upper limit value, the operation of each counter ( You may comprise so that counting may be complete | finished.
