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 first special symbol display unit 61 corresponds to the first symbol display unit of the present invention, the second special symbol display unit 62 corresponds to the second symbol display unit of the present invention, and the first special symbol display unit 61 The first special symbol displayed corresponds to the first symbol of the present invention, and the second special symbol displayed on the second special symbol display unit 62 corresponds to the second symbol of the present invention.

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. Second start port 28b
When the opening time extension function that extends the opening time of the non-operating (normal time), a short opening pattern with a first opening time (for example, 1-2 seconds) is set, and the opening time extending function is activated Sometimes a long-time release pattern is set in which a second release time (for example, 4 to 6 seconds) longer than the first release time is set. The open time extension function will be described later. When the opening time extension function is not activated, the probability that a game ball enters the second start port 28b is low, so the game ball is mainly the first
The ball enters the starting port 28a, and the symbol variation game by the first special symbol is mainly performed.
On the other hand, when the opening time extension function is activated, the probability that a game ball enters the second start port 28b is high, so that the game ball mainly enters the second start port 28b and the second described later. Combined with the special symbol priority variation function, the symbol variation game with the second special symbol is executed more frequently than when the opening time extension function is not activated.

In the present embodiment, a random number for determining whether or not a normal symbol is provided is prepared. This random number for determining whether or not a normal symbol is used determines whether or not the second starting port 28b is activated when the game ball passes through the normal symbol operating gate 27. It is used to determine whether or not the symbol is normal (whether to be in an open state). The normal symbol success / failure random number is set in advance with a hit value, and the normal symbol success / failure determination random number acquired at the timing when the game ball passes the normal symbol operation gate 27 matches the win value. Determined. When it is determined 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.

In this embodiment, when the opening time extending function for extending the opening time of the second start port 28b is activated, the normal symbol display section 51 displays a stop display compared to when the opening time extending function is not activated (normal time). There is a high possibility (probability) that a normal symbol to be hit will become a normal symbol display mode. That is, when the open time extension function is activated, the probability that the result of the normal symbol success / failure determination becomes a hit is higher than when the open time extension function is not activated (the probability variation function of the normal symbol success / failure determination). In this embodiment, when the open time extension function is activated, the open time extension function is not activated (normal time).
Compared to, the fluctuation time of normal symbols is shorter (the normal figure fluctuation time reduction function). This
In this embodiment, when the opening time extension function is activated, the actions of the “opening time extension function”, “general symbol fluctuation time shortening function”, and “probability fluctuation function of normal symbol success / failure determination” are combined. 2 Start port 2
The opening frequency of 8b is improved compared to when the opening time extension function is not operated (normal time). “Opening time extension function” for improving the opening frequency of the second start port 28b in this way.
, The operation control of the "normal map fluctuation time shortening function" and "ordinary symbol success / failure probability variation function"
This is performed by the main control unit 200 described later, and the main control unit 200 corresponds to the release frequency improving means of the present invention.

Here, normal symbol holding will be described. The normal symbol hold display section 52 displays the number of normal symbols held, and the number of game balls that have passed the normal symbol operation gate 27 is set to the maximum number of holds (4 in this embodiment).
Can be suspended. 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.

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 holding of the normal symbol and the holding of the normal symbol are performed by the main control unit 200 described later.

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 unit 62 is provided. Each special symbol display unit 61, 62 is composed of seven LEDs, and these LEDs
Thus, special symbols (first special symbol and second special symbol) are displayed respectively. 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 displayed for each LE
It is assumed that D is displayed in a blinking display that repeatedly turns on and off.

In the first special symbol display unit 61, when the game ball enters the first starting port 28a, the first special symbol starts to fluctuate, and after the predetermined time has elapsed, the first special symbol is stopped and displayed as a big hit symbol or a missed symbol. In the second special symbol display section 62, when the game ball enters the second starting port 28b, the second special symbol starts to change, and after the predetermined time has elapsed, the second special symbol is stopped and displayed as a big hit symbol or a missed symbol. Is done. 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.

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

The first big hit lottery random number and the first special symbol determining random number are acquired with the game ball entering the first starting port 28a, and the acquired first big hit lottery random number and the first special symbol determining random number are acquired. 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, the second big hit lottery random number and the second special symbol determining random number are acquired, and a predetermined area (second reserved storage area) of the RAM of the main control unit 200 is acquired. ) Is stored as a hold (second special symbol hold).

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 (memory number) of special symbol random numbers (first big lottery 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 big lottery random number as the game ball enters the first starting port 28a. This also corresponds to the number of symbols for design determination random numbers. And
The first special symbol holding number is digested every time the first big winning lottery is performed and the variable display of the first special symbol is started, and decreases by one.

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 (memory number) of special symbol random numbers (second big hit lottery random number, second special symbol determination random number). In the present embodiment, the second special symbol determination random number is acquired together with the second big hit lottery random number as the game ball enters the second starting port 28b. This also corresponds to the number of symbols for design determination random numbers. The second special symbol holding number is digested every time the second big winning lottery is performed and the variation display of the second special symbol is started, and decreases by one. The storage of the first and second special symbols and the reservation and digestion are performed by the main control unit 200 described later. For this reason, the main controller 200 corresponds to the first big hit lottery random number storage means and the second big hit lottery random number storage means of the present invention.

The big hit lottery random number is set with a winning value for determining whether or not the game is successful.
If the jackpot lottery random number acquired at the timing of entering a or the second starting port 28b matches the winning value, the jackpot is determined. The first big hit lottery is performed when the first special symbol starts variable display, and the second big hit lottery is performed when the second special symbol starts variable display.

When the first jackpot lottery random number matches the winning value, it is determined that the jackpot is successful, and the first special symbol that is stopped and displayed by the first special symbol display unit 61 is determined as the jackpot symbol. If the first big hit lottery random number does not match the winning value, it is out of place and the first special symbol display unit 61 stops and displays the first
The special symbol is removed and the symbol is determined.

Similarly, when the second big winning lottery random number matches the winning value, it is determined as a big hit, and the second special symbol stopped and displayed on the second special symbol display unit 62 is determined as the big hit symbol. When the second big hit lottery random number does not coincide with the winning value, it is a failure, and the second special symbol that is stopped and displayed by the second special symbol display unit 62 is determined to be a loss symbol.

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 the first special symbol hold and the number of the second special symbol hold are 1 or more, the second special symbol starts to fluctuate preferentially from the first special symbol, and the hold of the second special symbol is stopped. Digested preferentially.
Then, when the first special symbol hold count is 1 or more and the second special symbol hold count becomes zero, the variable display of the first special symbol is executed.

The special symbol is configured to change and display according to a predetermined change pattern. This variation pattern defines the variation time of the special symbol and the presence / absence of the reach effect in the variation (effect content). The variation pattern of the special symbol is when the big hit lottery is executed.
A variation pattern table storing a plurality of variation patterns is selected by lottery. A plurality of special symbol variation pattern tables are prepared, and each is selected and used according to the gaming state (special symbol variation mode). The special symbol variation pattern table used when the open time extension function is activated will be described later.

In addition, the 1st big hit lottery, the 2nd big hit lottery, determination of the variation mode (variation pattern) of the special symbol, the determination of the special symbol stop pattern, the fluctuation display and stop display of the first special symbol, the fluctuation display of the second special symbol The stop display and the priority change of the second special symbol are configured to be performed by the main control unit 200 described later. Therefore, the main control unit 200 corresponds to the first symbol game executing means, the second symbol game executing means, and the second symbol priority changing means of the present invention.

Next, the jackpot game (special game) will be described. When the special symbol stopped and displayed in the special symbol display unit 61 is the aforementioned jackpot symbol (when the result of the jackpot lottery is a jackpot)
In addition, the main control unit 200 starts a big hit game (special game) which is relatively advantageous to the player. The big hit game is started by setting the big hit game flag to ON.
In other words, by opening and closing the big prize opening 33a a plurality of times, a profit (prize ball) is given to the player regarding the entry of the game ball into the big prize opening 33a. The big hit game is realized by repeatedly executing a big hit game process by the main control unit 200 which will be described later, and the main control unit 200 corresponds to the privilege granting means of the present invention.

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 end condition, the opening time of the special winning opening 33a is a specified time (30 seconds in this embodiment).
Or when the number of game balls that have entered the open large winning opening 33a has reached a specified number (10 in this embodiment).

In the case of one round game from the start to the end of the open state of this special winning opening 33a,
The big hit game ends when a predetermined number of round games are played. In the big prize device 33,
After the opening of the big prize opening 33a is completed, that is, after a predetermined time has passed since the big prize opening 33a is closed, the big prize opening 33a is again opened and the next round game starts.
The grand prize opening 33 is such that one round of game starts from the opening to the end of the big prize opening 33a.
The opening / closing operation of a is continuously repeated until a predetermined maximum number of continuous rounds is completed.

In this embodiment, a plurality of maximum continuous round numbers are set. Specifically, two types of 2 rounds and 15 rounds are set as the maximum number of continuous rounds. 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 is the first of 15 rounds.
A “15R jackpot game” that generates a jackpot game (hereinafter also referred to as “15R jackpot game”) and a second round of second jackpot game (hereinafter also referred to as “2R jackpot game”) are generated. “2R jackpot symbol” is provided.

The “15R jackpot game” and the “2R jackpot game” have different opening times (specified times) for the big winning opening 33a for one round. The opening time of the grand prize winning port 33a of the “15R jackpot game” is set as a time when the prescribed number (10) of balls to the big winning port 33a and the prize ball payout associated therewith are extremely likely to be executed. It is desirable that it is 25 seconds to 30 seconds, and is set to “26 seconds” in this embodiment. The opening time of the big winning opening 33a of the “2R jackpot game” is set as a time when the prescribed number (10 pieces) of entering the big winning opening 33a and the possibility of executing the winning ball payout are extremely low. In this embodiment, it is set to “0.2 seconds”.

The first jackpot game (15R jackpot game) is a “long-term jackpot game” with a long execution period, and the possibility of entering a prescribed number (10) of balls into the big prize winning opening 33a and the prize ball payout associated therewith. Is extremely high, and is positioned as a “big hit game with a game” that allows a large number of prize balls to be acquired. Also, the second jackpot game (2R jackpot game) is a “short-term jackpot game” with a short execution period, and a prescribed number (10) of balls are entered into the big winning opening 33a and the associated prize ball is paid out. The possibility is extremely low, and it is positioned as a “big hit game without a ball” that makes it difficult to obtain a large number of prize balls.

The first jackpot game (15R jackpot game) includes a first probability variation jackpot game (15R probability variation jackpot game) in which the probability variation function is activated after completion, and a first normal jackpot game (15R regular jackpot game in which the probability variation function is not activated after termination). ). Also, the second jackpot game (2R jackpot game)
Consists only of the second normal jackpot game (2R normal jackpot game) in which the probability variation function does not operate after completion.

When the first special symbol is stopped and displayed as a big hit symbol, either the first probability big hit game (15R probability variable big hit game) or the second normal big hit game (2R normal big hit game) is set to be executed. Yes. On the other hand, if the second special symbol is stopped and displayed as a jackpot symbol,
Either the normal big hit game (15R normal big hit game) or the first probability variable big hit game (15R probability big hit game) is set to be executed. In this way, the jackpot game with the first special symbol includes the second jackpot game (2R jackpot game) which is “a jackpot without hitting”, and therefore when the jackpot game is executed with the second special symbol. However, the profit that the player can obtain is greater than when the big hit game is executed by the first special symbol.

In the gaming machine of this embodiment, after the big hit game, the variable time shortening function and the open time extending function,
A specific game (a so-called short-time game and a probability-changing game) in which the probability variation function operates 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. The variable time shortening function and the open time extending function start simultaneously and end simultaneously. 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”.

In the gaming machine of this embodiment, after the big hit game, the variable time shortening function and the open time extending function,
A special game (a so-called short-time game and a probable game) in which the probability variation function operates 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.

In the gaming machine 1 of this embodiment, when the result of the big hit lottery is a big hit and the stop symbol of the special symbol is a normal big hit symbol (2R normal big hit symbol, 15R normal big hit symbol), after the big hit game ends, The variable time shortening function and the opening time extending function for extending the opening time of the second start port 28b beyond the set time (normal time) at the normal time start to operate, and the short time game is started. The short-time game is realized by the control of the main control unit 200. 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, 0.1 second) to the second opening time (for example, 4 to 6 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 time extension function is not activated). The fluctuation time shortening function and the opening time extension function operate after the big hit game is finished until the next big hit game is started, or until the number of fluctuations of the special symbol reaches a predetermined number (100 times in this example). .

Also, if the result of the big hit lottery is a big hit and the special symbol stop symbol is a probable big hit symbol (1
In the case of 5R probability variation big hit symbol), after the big hit game ends, the probability variation function starts to operate, and the probability variation game starts. Probability game is realized by the control of the main control unit 200,
In this probability variation game, a probability variation function is activated that changes (improves) the probability that the result of the jackpot lottery will be a jackpot, that is, the probability that the special symbol is stopped and displayed with the jackpot symbol. Thus, a gaming state in which the probability variation function is activated is also referred to as a “high probability state”, and a gaming state in which the probability variation function is not activated is also referred to as a “low probability state”. In this embodiment, after the jackpot game related to the probability variation jackpot, the “high probability state” is set until the next jackpot game is started.

While the probability variation function is in operation, the probability of winning the jackpot lottery increases as the jackpot winning value for the jackpot lottery increases. Specifically, a low probability lottery table and a high probability lottery table in which the number of jackpot winning values is set larger than that of the low probability lottery table are prepared as the lottery tables in which the big hit winning value is set. During normal games (when the probability variation function is not activated), by performing a big hit lottery using the low probability lottery table, the probability that the big hit lottery random number matches the big hit winning value will be low, and during the probability change game ( When the probability variation function is activated), the probability of the jackpot lottery random number matching the jackpot winning value becomes high by performing the jackpot lottery using the high probability lottery table.

The variation time shortening function, the open time extension function, and the probability variation function are realized by the control of the main control unit 200, and the main control unit 200 constitutes a probability variation unit.

Next, the variation pattern table of special symbols will be described. FIG. 3A shows an example of the first special symbol variation pattern table used when the open time extension function is activated.
) Shows an example of the second special symbol variation pattern table used when the open time extension function is activated. These variation pattern tables are stored in the ROM of the main control unit 200.

As shown in FIG. 3 (a), the first special symbol variation pattern table used when the open time extension function is activated is provided with three types of variation variation pattern tables and one variation variation pattern table. ing. When the first big hit lottery is missed, any of the variation pattern tables A to C for miss is used, and when the first big hit lottery is a big hit, the winning variation pattern table is used.

The three types of first special symbol deviation variation pattern tables are selected according to the number of variations of the special symbol after the opening time extension function is activated. Specifically, when the number of fluctuations of the special symbol after the start of the opening time extension function is 1 to 49, the first special symbol deviation variation pattern table A is used, and in the case of 50 times, the first special symbol variation pattern A is used. The variation pattern table B for off-design is used, and 5
In the case of 1 to 100 times, the first special symbol deviation variation pattern table C is used.

The first special symbol variation pattern A includes the first special symbol variation pattern 1 (variation time 2 seconds), and the first special symbol variation pattern B includes the first special symbol variation. Pattern 2 (variation time 7 seconds) is included, and the first special symbol deviation variation pattern table C includes the first special symbol variation pattern 3 (variation time 14 seconds). First
The special symbol variation pattern 1 (variation time 2 seconds) is configured as a “short-term variation pattern”, and the first special symbol variation pattern 2 (variation time 7 seconds) is configured as an “intermediate variation pattern”. Pattern 3 (variation time 14 seconds) is configured as a “long-time variation pattern”. As a result, the variation mode of the first special symbol changes from the short variation mode (2 seconds) to the long variation mode (14 seconds), with the number of variations of the special symbol after the start of the opening time extension function being activated being “50 times”. ). When the first special symbol is variably displayed in the first special symbol variation pattern 2 (7 seconds), a variation mode transition effect is provided for notifying that the variation mode of the special symbol is transitioned.

The first special symbol variation pattern 4 (variation time 5 seconds) is set in the first special symbol variation pattern table. In order for the first special symbol to stop display with the big hit symbol, either the first big hit game (2R big hit game) or the second big hit game (15R big hit game) is started, so the first special symbol is the first special symbol. When the special symbol variation pattern 4 is variably displayed, a lottery effect (disadvantage effect) is performed in the display area of the effect display device 25 in which a lottery lottery (2 rounds or 15 rounds) is assigned.

As shown in FIG. 3 (b), the second special symbol variation pattern table used when the open time extension function is operated is provided with three types of variation variation pattern tables and one variation variation pattern table. ing. When the second big hit lottery is missed, any of the variation pattern tables A to C for miss is used, and when the second big hit lottery is a big hit, the winning variation pattern table is used.

The three types of variation patterns tables for the second special symbol removal are selected according to the number of variations of the special symbol after the start of the opening time extension function. Specifically, when the number of fluctuations of the special symbol after the start of the opening time extension function is 1 to 49, the second special symbol deviation variation pattern table A is used. The variation pattern table B for off-design is used, and 5
In the case of 1 to 100 times, the second special symbol deviation variation pattern table C is used.

The second special symbol deviation variation pattern table A includes the second special symbol variation pattern 1 (variation time 2 seconds), and the second special symbol variation variation pattern table B includes the second special symbol variation pattern B. Pattern 2 (variation time 7 seconds) is included, and the second special symbol deviation variation pattern table C includes the second special symbol variation pattern 3 (variation time 10 seconds) and the second special symbol variation pattern 1 (variation). Time 2 seconds). Second special symbol variation pattern 1 (variation time 2
Second) is configured as a “short time variation pattern”, the second special symbol variation pattern 2 (variation time 7 seconds) is configured as an “intermediate variation pattern”, and the second special symbol variation pattern 3 (variation time 10 seconds) is It is configured as a “long-time variation pattern”. In the second special symbol deviation variation pattern table C, when the second special symbol retention number at the start of the second special symbol variation is “0”, “1”, the variation display start of the first special symbol is suppressed. Therefore, the second special symbol variation pattern 3
(Variation time 10 seconds) is selected, and the number of second special symbol hold at the start of the second special symbol variation is “2”.
In the case of “4”, the second special symbol variation pattern 1 (variation time 2 seconds) is selected in order to digest the second special symbol suspension at high speed. As a result, the variation mode of the second special symbol changes from the short-time variation mode (2 seconds) to the long-term variation mode (10 seconds) with the boundary of the number of variations of the special symbol after the start of the opening time extension function operation being “50 times”. ). When the second special symbol is variably displayed with the second special symbol variation pattern 2 (7 seconds), a variation mode transition effect is provided for notifying that the variation mode of the special symbol is transitioned.

The second special symbol variation pattern 4 (variation time 5 seconds) is set in the second special symbol variation pattern table. When the second special symbol is stopped and displayed as a big hit symbol, only the second big hit game (15R big hit game) is started to be executed. Is the second jackpot game (in the display area of the effect display device 25).
A 15R big hit finalizing effect (advantageous effect) indicating that the 15R big hit game has been finalized is executed.

As described above, in the present embodiment, the variation mode of the first special symbol and the second special symbol is changed at a predetermined number of times (50 in the present embodiment) after the opening time extension function is activated. ,
The "special figure 1 suppression mode" having a low fluctuation display frequency of the first special symbol is switched from the "special figure 1 promotion mode" having a high fluctuation display frequency of the first special symbol, which is disadvantageous compared to the second special symbol. In the first half of the opening time extension function operation period (the number of special symbol fluctuations is between 1 and 49), the first special symbol and the second special symbol
Since the variation time of the special symbol is set to a short time, a game ball enters the second start port 28b while the second special symbol is variably displayed, and the second special symbol holding number is increased. And the digestion speed of the first special symbol hold and the second special symbol hold increases. As a result, in the second half of the open time extension function operation period, the advantageous second special symbol holding number often becomes zero, and the fluctuation display of the disadvantageous first special symbol is promoted, and is often performed. Period ".

On the other hand, in the second half of the operating period of the extended open time function (the number of special symbol fluctuations is between 51 and 100), the second special symbol holding number is less than the prescribed number (“1” in this embodiment). Since the variation time of the symbol is set to be a long time (“10 seconds” in this embodiment), the game ball is made to enter the second start port 28b as compared with the first half of the opening time extension function operation period and the second time. The number of special symbol reservations can be increased. Furthermore, the second half of the opening time extension function operation period (the number of special symbol fluctuations is 51
˜100 times), since the variation time of the first special symbol is set to a long time (“14 seconds” in this embodiment), even if the second special symbol hold number becomes zero While the first special symbol is variably displayed, a game ball can enter the second start port 28b to increase the second special symbol hold number. As a result, in the first half of the opening time extension function operating period,
The variation display of the special symbol is suppressed, and the “advantageous game period” in which the advantageous second special symbol is mainly variably displayed.

From the above, the first special symbol “short-time variation pattern (first special symbol variation pattern 1
) ”And the second special symbol“ short-time fluctuation pattern (second special symbol fluctuation pattern 1) ”, the fluctuation time is used to digest the second special symbol hold and promote the start of variable display of the first special symbol. It is set as the fluctuation time for fluctuation promotion necessary to do this.
Also, the fluctuation time defined by the “long-time variation pattern (first special symbol variation pattern 3)” of the first special symbol and the “long-term variation pattern (second special symbol variation pattern 3)” of the second special symbol is This is set as a variation suppressing variation time necessary for increasing the second special symbol hold and suppressing the variation display start of the first special symbol. The relationship between the variation suppression variation time and the variation promotion variation time is sufficient if the variation suppression variation time is greater than the variation promotion variation time, whereby the frequency of entering the game ball into the second start port 28b differs. The occurrence frequency (decrease rate) of the second special symbol hold may be different. Note that the variation time of the first special symbol and the second special symbol by the “long-time variation pattern” corresponds to the first variation time of the present invention, and the first special symbol and the second special symbol by the “short-time variation pattern”. The fluctuation time corresponds to the second fluctuation time of the present invention.

Next, the effect symbols displayed on the effect display device 25 will be described. In the display area of the effect display device 25, an effect symbol display unit 25a for displaying effect symbols is provided.

Yes. 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). Each symbol display area is "1"-
Each symbol consisting of “9” can be displayed.

When the first special symbol or the second special symbol is stopped and displayed in any of the symbols, the first symbol or the second special symbol is started.
The special symbol or the second special symbol is stopped and displayed with a symbol corresponding to the stop symbol. In the production design,
The symbol combination with the same three digits corresponds to the jackpot symbol of the special symbol, and the other symbol combinations (that is, the non-identical three-digit pattern corresponds to the off symbol of the special symbol).

The variation pattern (variation pattern) of the effect symbol and the stop symbol are determined based on the variation pattern designation command and the stop information designation command transmitted from the main control unit 200.
60. Here, the main control unit 200 to the sub-control unit 2

(Second start port 28b
To the open state). In the normal symbol game process, the normal symbol variation display and stop display are performed as described above, and when the normal symbol is stopped and displayed in the normal symbol display mode, the second start port 28b is activated. I do. When the second start port 28b is actuated, the pair of blade pieces open to the left and right, and the second start port 28b is opened.

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

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

First, it is determined whether or not the first start port 28a has won a prize (a game ball has entered) (S501a),
When it is determined that the first start port 28a has not won a prize (S501a: NO). S50
The process proceeds to 1d. On the other hand, when it is determined that the first start port 28a has won a prize (S5
01a: YES), it is determined whether or not the number of first special symbol hold 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 random number for the first special symbol is
The first big hit lottery random number, the first special symbol hit random number for determining symbols, the 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 (S501d), and the second starting port 28b is determined.
If it is determined that the player has not won a prize (S501d: NO). The start opening winning process is terminated. On the other hand, when it is determined that the second start port 28b has 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 reservation number is not less than 4 (4 or more) (S501e: NO)
), When the start opening winning process is terminated and it is determined that the second special symbol hold number is less than 4 (S501e: YES), the second special symbol random number (second symbol success / failure determination information) is acquired. (S501f). The second special symbol random number includes a second big hit lottery 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. 6A, it is determined whether or not the jackpot game is being played (whether or not the jackpot game flag is ON) (S502). As a result, when it is determined that the big hit game is being played (the big hit game flag is ON) (S502: YES), the special symbol game process is terminated,
When it is determined that the jackpot game is not being played (the jackpot game flag is OFF) (S50)
2: NO), it is determined whether the special symbol (the first special symbol or the second special symbol) is changing (S503).

As a result, when it is determined that the special symbol is changing (S503: YES), the process proceeds to S510 described later, and when it is determined that the special symbol is not changing (S503:
NO), it is determined whether or not it is during the special symbol stop display time (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”. If it is determined that it is during the special symbol stop display time (S504: YES), the process proceeds to S514 described later, and if it is determined that it is not during the special symbol stop display time (S504). : NO), it is determined whether or not the number of second special symbol hold 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 reservation number being zero (S507: YES)
Then, the special symbol game process is terminated. On the other hand, when it is determined that the number of first special symbol hold is not zero (S507: NO), a first special symbol variation display process is performed (S508).

On the other hand, if it is determined in S506 that the number of second special symbol reservations is not zero (
S506: NO), the second special symbol variation display process is performed (S509). That is, when it is determined in the determination process of S506 that the second special symbol holding number is not zero (S506: NO),
Even if the number of first special symbol hold is not zero (even if it is 1 or more), the variation display process of the second special symbol 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 process (S508) and the second special symbol variation display process (S50).
9) will be described based on the flowcharts of FIGS. The first special symbol variation display process and the second special symbol variation display process are processes having the same contents except for the portions of the “first special symbol” and the “second special symbol”. The “special symbol” in FIG. 4 becomes “first special symbol” in the first special symbol variation display processing, and “second special symbol” in the second special symbol variation display processing. Here, the first special symbol variation display process (S508) will be described, and the description of the second special symbol variation display process (S509) will be omitted.

First, the first stored in a predetermined area (first reserved storage area) of the RAM of the main controller 200.
A big hit lottery random number (a random number for determination of success / failure acquired at the time of entering a game ball into the first start port 28a) is read (S508a), and a first big hit lottery is performed (S508b). In the first jackpot lottery, if the probability variation function is in operation (probability change game), the success / failure determination at the time of probability variation, that is, the determination of success / failure is made in a state where the probability that the determination result is a big hit (high probability state). If it is determined that the probability variation function is not in operation (during normal game), it is determined whether or not there is a non-probability change, that is, whether the determination result is a big hit (low probability state). I do.

Next, it is determined whether or not the open time extension function is in operation (S508c). As a result, when it is determined that the opening time extension function is in operation (S508c: YES), the first special symbol variation pattern setting process is performed when the opening time extension function is operated (S508d). Here, the first special symbol variation pattern setting process when the open time extension function is activated will be described based on the flowchart of FIG.

First, it is determined whether or not the result of the first big hit lottery is a big hit (S550). As a result, when it is determined that the result of the first big hit lottery is not big hit (S550: NO), it is determined whether or not the variation pattern change counter exceeds “50” (S551). The “fluctuation pattern change counter” is for counting the total number of variable display times of the first special symbol and the second special symbol performed during the operation period of the fluctuation time shortening function and the opening time extension function. At the end, an initial value (in this embodiment “
100 ”) is set, and each time the special symbol (the first special symbol and the second special symbol) is variably displayed, it is configured as a countdown type counter that is subtracted in the process of S527 (FIG. 6B). When the variation pattern change counter is updated, a variation pattern change counter specifying command indicating the counter value of the variation pattern change counter is transmitted to the sub-control unit 260 one by one (not shown).

As a result, when it is determined that the fluctuation pattern change counter exceeds “50” (S551: YES), the number of fluctuations of the special symbol after the start of the open time extension function is “1” to “
49 ", the first special symbol variation pattern 1 (variation time 2 seconds) is set based on the first special symbol deviation variation pattern table A (S552). In the second special symbol variation pattern setting process (S509d), the second special symbol variation pattern 1 (variation time 2 seconds) is set.

On the other hand, if it is determined that the variation pattern change counter does not exceed “50” (
S551: NO), it is determined whether or not the variation pattern change counter is “50” (S5).
53). As a result, when it is determined that the variation pattern change counter is “50” (
S553: YES), the first special symbol variation pattern 2 (variation time 7 seconds) is set based on the second special symbol deviation variation pattern table B (S554). In the second special symbol variation pattern setting process (S509d), the second special symbol variation pattern 2 (variation time 7 seconds) is set.

On the other hand, when it is determined that the variation pattern change counter is not “50” (S553:
YES), since the number of fluctuations of the special symbol after the start of the opening time extension function is “51” to “100”, the first special symbol variation pattern 3 (variation based on the first special symbol deviation variation pattern table C) Time 14 seconds) is set (S555). In the second special symbol variation pattern setting process (S509d), the second special symbol variation pattern 3 (variation time 10 seconds) is set when the number of second special symbol reservations is “0” or “1”. , 2nd special symbol hold number is "2"-"4
", The second special symbol variation pattern 1 (variation time 2 seconds) is set.

If it is determined in S550 that the result of the first big hit lottery is a big hit (S550: YES), the first special symbol variation pattern 4 is based on the first special symbol variation pattern table. (Variation time 5 seconds) is set (S556). In the second special symbol variation pattern setting process (S509d), the second special symbol variation pattern 4 (variation time 5 seconds)
Is set.

Next, returning to FIG. 8, if it is determined in S508c that the opening time extension function is not operating (S508c: YES), the first special symbol variation pattern setting process when the opening time extension function is not operating. (S508e). This process is the same as the special symbol variation pattern setting process performed by a known pachinko machine equipped with a special symbol. That is, the current gaming state (
Based on the result of the first big hit lottery, the variation pattern of the first special symbol is set using the first special symbol variation pattern table corresponding to the normal game).

When the special symbol variation pattern setting process (S508d, S508e) is completed as described above, the process proceeds to S508f in FIG. 8, and the symbol determining random number (first number) stored in the predetermined area of the RAM of the main control unit 200 is displayed. The first special symbol determination random number acquired at the time of entering the game ball into the 1 start port 28a is read (S508f).

Next, a stop symbol is determined (S508i). As the stop symbol of the first special symbol, the type of stop symbol of the first special symbol (the LED display pattern in the first special symbol display unit 61) is determined using the random number for symbol determination read in S508f.

Next, according to the special symbol variation pattern set in S508d and S508e and the stop symbol determined in S508g, the first special symbol display unit 61 starts the variation display of the first special symbol (S508h), and is accompanied by this. Thus, the first special symbol variation pattern designation command and stop information designation command as the symbol variation start command are transmitted to the sub-control unit 260 (S50).
8i). The variation pattern designation command is a command for designating the variation pattern of the first special symbol set in S508d and S508e, and the first special symbol information designation command is a command for designating the stop symbol of the first special symbol. When the fluctuation pattern designation command and the stop information designation command are transmitted to the sub-control unit 260, the symbol variation effect (under the control of the sub-control unit 260 and the effect display control unit 280 that have received these commands (design variation start command) (
The production symbol variation display) is started. Then, 1 is subtracted from the first special symbol holding number (S50).
8j). The above is the processing when starting the variable display of the first special symbol.

Next, returning to FIG. 6A, if it is determined in S503 that the special symbol (the first special symbol or the second special symbol) is changing (S503: YES), the changing special symbol. It is determined whether or not the variable display time has elapsed (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 the case (S510: YES)
), The special symbol fluctuation display is stopped (S511), a symbol stop command indicating that the special symbol fluctuation display is stopped is transmitted to the sub-control unit 260 (S512), and the special symbol stop display time is set (S512). S513).

Next, it is determined whether or not the special symbol stop symbol display time has elapsed (S514). As a result, when it is determined that the special symbol stop symbol display time has not elapsed (S514: N
O) When the special symbol game process is finished and it is determined that the special symbol stop symbol display time has elapsed (S514: YES), it is determined whether or not the special symbol stop symbol is a jackpot symbol. Determination is made (S515 in FIG. 6B). As a result, when it is determined that the special symbol stop symbol is a big hit symbol (S515: YES), the type of the big hit (2R big hit, 15R big hit) and the current gaming state flag are stored in the reference buffer at the time of the big hit end. The state of (probability change flag, change shortening flag, release extension flag) is set (S516).

Next, the jackpot game flag is set to ON (S518), and the number of rounds of the jackpot game is set to “
Set to “2 rounds” or “15 rounds” (S519). Thereby, the big hit game is started.

Next, it is determined whether or not the probability variation flag is ON (S520). If it is determined that the probability variation flag is ON (S520: YES), the probability variation flag is set to OFF (S521).
, The process proceeds to S522. On the other hand, if it is determined that the probability variation flag is not ON (S
520: NO), the process proceeds to S522 as it is.

In the process of S522, it is determined whether or not the fluctuation shortening flag is ON. If it is determined that the fluctuation shortening flag is not ON (S522: NO), the special symbol game process is terminated as it is. On the other hand, when it is determined that the fluctuation shortening flag is ON (S522: YES),
The fluctuation shortening flag is set to OFF (S523), and the open extension flag is set to OFF (S524). Thereby, along with the start of the big hit game, all of the probability variation function, the variation time shortening function, and the open time extension function are stopped.

Next, when it is determined in the determination process of S515 that the special symbol stopped and displayed on the special symbol display unit 61 is not a big hit symbol (in other words, a symbol that is out of place) (S5).
15: NO), it is determined whether or not the open extension flag is ON (S525). As a result,
If it is determined that the release extension flag is not ON (S525: NO), the special symbol game process is terminated. If it is determined that the extension extension flag is ON (S525: YES), the extension number counter is set. 1 is subtracted (S526), and 1 is subtracted from the variation pattern change counter (S527), and it is determined whether or not the open extension number counter has become zero (S528).
.

If it is determined that the opening extension number counter is not zero (S528)
: NO), when it is determined that the special symbol game process is finished and the release extension counter is zero (S528: YES), the fluctuation shortening flag is turned off (S529), and the release extension flag is turned off. (S530). As a result, the variable time shortening function and the open time extending function are deactivated.

Next, the jackpot game process (S600) will be described based on the flowchart of FIG. First, it is determined whether or not the jackpot game is being played (whether or not the jackpot game flag is ON) (S601). As a result, when it is determined that the jackpot game is not being played (the jackpot game flag is OFF) (S601: NO), the jackpot game process is terminated and the jackpot game is being played (the jackpot game flag is ON). Is determined (S601: YES), it is determined whether or not the special winning opening 33a is being opened (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).

As a result, when it is determined that the prescribed number of winnings has not been won in the big winning opening 33a (S6).
04: NO), the jackpot game process is terminated, and it is determined that the predetermined winning number is won in the big winning opening 33a (S604: YES) or it is determined that the opening time of the big winning opening 33a has elapsed. If it is made (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 (S60).
2: NO), it is determined whether or not the jackpot game end condition is satisfied (S606). S606
In the determination process, it is determined whether or not the number of rounds of the big hit game has reached the number of rounds (15 rounds or two rounds) set at the start of the big hit game (in the process of S519 in FIG. 6B).

As a result, when it is determined that the jackpot game end condition is not satisfied (S606: N)
O), it is determined whether or not the closing time (interval time) of the special winning opening 33a has passed (
S607) When it is determined that the closing time of the special winning opening 33a has not elapsed (S60)
7: NO), the big hit game process is finished, and when it is determined that the closing time of the big prize opening 33a has passed (S607: YES), the big prize opening 33a is opened (S608).

If it is determined in S606 that the big hit game end condition is satisfied (S606)
: YES), the big hit game flag is set to OFF (S609). As a result, the big hit game ends.

Next, it is determined whether or not the type of jackpot symbol that has caused the start of the terminated jackpot game is a probability variation jackpot symbol (S610).

As a result, if it is determined that the type of jackpot symbol is “probability jackpot symbol” (S6
10: YES), the probability variation flag is set to ON (S611). As a result, the probability variation function starts to operate. On the other hand, when it is determined that the type of jackpot symbol is not “probable variation jackpot symbol” (“normally jackpot symbol”) (S610: NO), the probability variation flag is not set to ON (S611), The process proceeds to S612. Then, the fluctuation shortening flag is set to ON (S612), the release extension flag is set to ON (S613), and values for determining the operation period of the fluctuation time reduction function and the release time extension function in the release extension number counter (
The initial value is set (S614). As a result, the variable time shortening function and the open time extending function are activated. In this embodiment, when the type of jackpot symbol that triggered the terminated jackpot game is a probabilistic jackpot symbol (S610: YES), “10,000” is set to the open extension counter. In the case of a normal jackpot symbol (S610: NO), “100” is set in the open extension number counter. As a result, the probability variation function is activated after the end of the jackpot game triggered by the stop display of the probability variation jackpot symbol,
The variation time shortening function and the opening time extension function are operated until the number of times of variation of the special symbol reaches 10,000. That is, all of the probability variation function, variation time shortening function, and opening time extension function are operated until the next big hit game is started. In addition, the probability variation function does not operate after the end of the big hit game triggered by the normal jackpot symbol stop display, and the variable time shortening function and the open time extension function reach the number of times the special symbol changes to 100 times. It works until.

After setting the initial value in the open extension number counter, “100” is set as the initial value of the variation pattern change counter (S615). In addition, the variation pattern change counter is set to “100” which is the same value after the end of the jackpot game triggered by the stop display of the probability variation jackpot symbol and after the end of the jackpot game triggered by the stop display of the normal jackpot symbol. Is done. In this embodiment, after the jackpot game is triggered by the stop display of the probability variation jackpot symbol, “10,000” is set in the open extension number counter, so that it exceeds 100 times during the operation of the probability variation function. The special symbol variation performed in this manner will cause the game to proceed in the variation pattern setting mode in the “special diagram 1 suppression mode” described above.

Here, the correspondence between the processing shown in the flowcharts of FIGS. 6 to 10 and each means of the present invention will be described. The processing of S501c (FIG. 7) is the first big hit lottery random number storing means of the present invention. “S501f processing (FIG. 7)” corresponds to the second big hit lottery random number storage means of the present invention, and “S508 processing (FIGS. 6A, 8)” is the first symbol game execution means. In response to "S
“Process 509 (FIG. 6A, FIG. 8)” corresponds to the second symbol game executing means, “Process S506 (FIG. 6A)” corresponds to the second symbol priority changing means, and “S601”. ~ S609 (FIG. 10) "corresponds to the privilege granting means," S613 (FIG. 10) "corresponds to the release frequency improving means, and" S552, S555 (FIG. 9) "is the variable time setting. Corresponds to the means.

In the present embodiment described above, in a gaming machine having the priority variation function of the second special symbol, the special symbol variation count reaches a predetermined number during the open time extension function operation in which the variation display of the second special symbol occurs frequently. In such a case, the second special symbol and the second special symbol can be
The special symbol hold is likely to increase, and it is easy to maintain the variable display of the second special symbol, and the frequency of starting the variable display of the first special symbol is reduced. Thereby, the novel game progress aspect that the change display start frequency of the 1st special symbol which is disadvantageous than the 2nd special symbol falls in the middle of the operation period of an open time extension function is realizable. As a result, there is a possibility that a 2R big hit game, which is disadvantageous to the 15R big hit game, is executed before the special symbol fluctuation count reaches the predetermined number during the opening time extension function operation (in the special figure 1 promotion mode). By giving the player a throbbing feeling due to being, and after the number of times the special symbol fluctuates during the opening time extension function operation (in the special figure 1 suppression mode), only the 15R big hit game is executed It becomes possible to give a sense of security to the player, and it is possible to improve the gaming interest during the opening time extension function.

In addition, by changing the operation mode of the opening time extension function by changing the opening time of the start port 28b during the opening time extension function operation, the frequency of increase / decrease of the second special symbol hold number is adjusted,
It is also conceivable to change the variation start frequency of the first special symbol. However, when the operation mode of the opening time extension function is changed, the game nature originally obtained by the operation of the opening time extension function (game ability to improve the frequency of entering the game ball into the second start port 28b) is impaired. There is a problem that it will be. On the other hand, as in this embodiment, by changing the variation time of the first special symbol and the second special symbol, the first special symbol of the first special symbol is not impaired without impairing the game nature originally obtained by the operation of the open time extension function. The variation start frequency can be changed, and the game interest during the opening time extension function can be improved.

(Second embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS. Hereinafter, description of the same parts as those in the first embodiment will be omitted, and only different parts will be described.

FIG. 11A shows the first special symbol variation pattern table used when the open time extension function of the second embodiment is operated, and FIG. 11B shows the open time extension function of the second embodiment. The fluctuation pattern table for 2nd special symbols used sometimes is shown.

As shown in FIG. 11 (a), the first used when the open time extension function of the second embodiment is operated.
The special symbol variation pattern table is provided with five types of variation variation pattern tables and one variation variation pattern table. When the first big hit lottery is missed, any of the deviation variation pattern tables D to H is used, and when the first big hit lottery is a big hit, the winning variation pattern table is used.

The five types of first special symbol removal variation pattern tables are selected according to the number of variations of the special symbol after the start of the opening time extension function. Specifically, when the number of fluctuations of the special symbol after the start of the opening time extension function is 1 to 19, the first special symbol deviation variation pattern table D is used. 1 special symbol deviation variation pattern table E is used, and in the case of 40 to 59 times, the first special symbol deviation variation pattern table F is used.
In the case of 0 to 79 times, the first special symbol deviation variation pattern table G is used, and 80 to 1
In the case of 00 times, the first special symbol deviation variation pattern table H is used.

The first special symbol variation pattern table D includes the first special symbol variation pattern 5 (variation time 2 seconds), and the first special symbol variation pattern table E includes the first special symbol variation pattern E. The pattern 6 (variation time 2 seconds) is included, and the first special symbol deviation variation pattern table F includes the first special symbol variation pattern 7 (variation time 6 seconds). The first special symbol The deviation variation pattern table G includes a first special symbol variation pattern 8 (variation time 10
Second) and the first special symbol deviation variation pattern table H includes the first special symbol variation pattern 9 (variation time 14 seconds).

As shown in FIG. 11 (b), the second used when the open time extension function of the second embodiment is operated.
The special symbol variation pattern table is provided with five types of variation variation pattern tables and one variation variation pattern table. When the second big hit lottery is out, any of the fluctuation pattern tables D to H for outage is used, and when the second big hit lottery is a big hit, the fluctuation pattern table for hit is used.

The five types of second special symbol removal variation pattern tables are selected according to the number of variations of the special symbol after the start of the opening time extension function. Specifically, when the number of fluctuations of the special symbol after the start of the opening time extension function is 1 to 19, the second special symbol deviation variation pattern table D is used. 2 special symbol deviation variation pattern table E is used, and in the case of 40 to 59 times, the second special symbol deviation variation pattern table F is used.
In the case of 0 to 79 times, the second special symbol deviation variation pattern table G is used, and 80 to 1
In the case of 00 times, the second special symbol deviation variation pattern table H is used.

The second special symbol variation pattern table D includes the second special symbol variation pattern 5 (variation time 2 seconds), and the second special symbol variation pattern table E includes the second special symbol variation pattern E. Pattern 6 (variation time 4 seconds) is included, and the second special symbol deviation variation pattern table F includes the second special symbol variation pattern 7 (variation time 6 seconds), and the second special symbol The deviation variation pattern table G includes the second special symbol variation pattern 8 (variation time 8 seconds), and the second special symbol variation pattern table H includes the second special symbol variation pattern 9 (variation). Time 10 seconds) and the second special symbol variation pattern 5 (variation time 2 seconds). In the second special symbol deviation variation pattern table H, when the number of the second special symbol hold at the start of the second special symbol variation is “0”, “1”, the variation display start of the first special symbol is suppressed. Therefore, when the second special symbol variation pattern 9 (variation time 10 seconds) is selected and the second special symbol retention number at the start of the second special symbol variation is “2” to “4”, the first special symbol variation pattern 9 is selected. In order to promote the start of symbol variation display, the second special symbol variation pattern 5 (variation time 2 seconds) is selected.

FIG. 12 is a flowchart showing the special symbol variation pattern setting process of the second embodiment, and corresponds to FIG. 10 of the first embodiment.

As shown in FIG. 12, in the second embodiment, when it is determined in S550 that the result of the first big hit lottery is a big win (S550), the variation pattern change counter is set to “80”.
It is determined whether or not the number exceeds “” (S557). As a result, when it is determined that the variation pattern change counter exceeds “80” (S557: YES), the number of variations of the special symbol after the start of the opening time extension function is “1” to “19”. Therefore, the first special symbol variation pattern 5 (variation time 2 seconds) is set based on the first special symbol deviation variation pattern table D (S558). In the second special symbol variation pattern setting process (S509d), the second
Special symbol variation pattern 5 (variation time 2 seconds) is set.

On the other hand, if it is determined that the variation pattern change counter does not exceed “80” (
S557: NO), it is determined whether or not the variation pattern change counter exceeds “60” (S559). As a result, when it is determined that the variation pattern change counter exceeds “60” (S559: YES), the number of variations of the special symbol after the start of the opening time extension function is “20” to “39”. Therefore, the first special symbol variation pattern 6 (variation time 4 seconds) is set based on the first special symbol deviation variation pattern table E (S560). The second

(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to FIGS. Hereinafter, description of the same parts as those in the above embodiments will be omitted, and only different parts will be described.

FIG. 13A shows the first special symbol variation pattern table used when the open time extension function of the third embodiment is operated, and FIG. 13B shows the open time extension function of the third embodiment. The fluctuation pattern table for 2nd special symbols used sometimes is shown.

As shown in FIG. 13 (a), the first used when the open time extension function of the third embodiment is operated.
The special symbol variation pattern table is provided with three types of variation variation pattern tables and one variation variation pattern table. When the first big hit lottery is out, any of the fluctuation pattern tables I to K for outage is used, and when the first big hit lottery is a big hit, the winning fluctuation pattern table is used.

The three types of first special symbol deviation variation pattern tables are selected according to the number of variations of the special symbol after the opening time extension function is activated. Specifically, when the number of fluctuations of the special symbol after the start of the opening time extension function is 1 to 39 times, the first special symbol deviation variation pattern table I is used, and when it is 40 to 59 times, One special symbol deviation variation pattern table J is used. In the case of 60 to 100 times, the first special symbol deviation variation pattern table K is used.

The first special symbol variation pattern table I includes the first special symbol variation pattern 10 (variation time 2 seconds), and the first special symbol variation pattern table J includes the first special symbol variation pattern J. The pattern 11 (variation time 14 seconds) is included, and the first special symbol deviation variation pattern table K includes the first special symbol variation pattern 10 (variation time 2 seconds).

As shown in FIG. 13B, the second used when the open time extension function of the third embodiment is operated.
The special symbol variation pattern table is provided with three types of variation variation pattern tables and one variation variation pattern table. When the second big hit lottery is missed, any of the variation pattern tables I to K for miss is used, and when the second big hit lottery is a big hit, the winning variation pattern table is used.

The three types of variation patterns tables for the second special symbol removal are selected according to the number of variations of the special symbol after the start of the opening time extension function. Specifically, when the number of changes in the special symbol after the start of the opening time extension function is 1 to 39, the second special symbol variation pattern table I is used, and in the case of 40 to 59, the first 2 special symbol removal variation pattern table J is used, and in the case of 60 to 100 times, second special symbol removal variation pattern table K is used.

The second special symbol variation pattern table I includes a second special symbol variation pattern 10 (variation time 2 seconds), and the first special symbol variation pattern table J includes a first special symbol variation. A pattern 11 (variation time 10 seconds) and a second special symbol variation pattern 10 (variation time 2 seconds) are included. The first special symbol variation pattern table K includes a first special symbol variation pattern 10 (variation). Time 2 seconds). In the second special symbol deviation variation pattern table J, when the number of second special symbol reservation at the start of the second special symbol variation is “0”, “1”, the second special symbol variation pattern 11 (variation time 10 Second), and when the number of second special symbol hold at the start of the second special symbol change is “2” to “4”, the second special symbol hold is used to digest the second special symbol hold at high speed. The fluctuation pattern 10 (fluctuation time 2 seconds) is selected.

FIG. 14 is a flowchart showing the special symbol variation pattern setting process of the third embodiment, and corresponds to FIG. 10 of the first embodiment.

As shown in FIG. 14, in the third embodiment, when it is determined in S550 that the result of the first big hit lottery is a big win (S550), the variation pattern change counter is set to “60”.
It is determined whether or not the number exceeds “” (S566). As a result, if it is determined that the variation pattern change counter exceeds “60” (S566: YES), the number of variations of the special symbol after the start of the opening time extension function is “1” to “39”. Therefore, the first special symbol variation pattern 10 (variation time 2 seconds) is set based on the first special symbol deviation variation pattern table I (S567). In the second special symbol variation pattern setting process (S509d), the second special symbol variation pattern 10 (variation time 2 seconds) is set.

On the other hand, if it is determined that the variation pattern change counter does not exceed “60” (
S566: NO), it is determined whether or not the variation pattern change counter exceeds “40” (S568). As a result, if it is determined that the variation pattern change counter exceeds “40” (S568: YES), the number of variations of the special symbol after the start of the opening time extension function is “40” to “59”. Therefore, the first special symbol variation pattern 11 (variation time 14 seconds) is set based on the first special symbol deviation variation pattern table J (S569). In addition,
In the second special symbol variation pattern setting process (S509d), the second special symbol hold number is “0”,
In the case of “1”, the second special symbol variation pattern 11 (variation time 10 seconds) is set, and the second
When the number of special symbol hold is “2” to “4”, the second special symbol variation pattern 10 (variation time 2 seconds) is set.

On the other hand, if it is determined that the variation pattern change counter does not exceed “40” (
S568: NO), the number of fluctuations of the special symbol after the start of the opening time extension function is “60” to “1”
Therefore, the first special symbol variation pattern 10 (variation time 2 seconds) is set based on the first special symbol deviation variation pattern table K (S570). In the second special symbol variation pattern setting process (S509d), the second special symbol variation pattern 10 (variation time 2 seconds) is set. In the third embodiment, the variation time of the first special symbol variation pattern 10 and the second special symbol variation pattern 10 corresponds to the third variation time of the present invention, and the process of S570 executed by the main control unit 200 ( FIG. 14) corresponds to the variable time setting means of the present invention.

In the third embodiment described above, when the number of changes in the special symbol reaches the first predetermined number after the start of the opening time extension function, the change time of the first special symbol and the second special symbol is extended. When the number of fluctuations of the special symbol reaches the second predetermined number of times, the temporarily shortened fluctuation times of the first special symbol and the second special symbol are restored. For this reason, the second special symbol hold tends to increase only during the period in which the fluctuation time of the first special symbol and the second special symbol is extended, and the frequency at which the fluctuation display of the first special symbol starts is reduced. As a result, it is possible to realize a novel game progression mode in which the frequency at which the variable display of the first special symbol, which is disadvantageous than the second special symbol, is started for a certain period can be suppressed during the operation period of the open time extension function. In addition, it is possible to improve the gaming interest during the opening time extension function.

(Other embodiments)
As mentioned above, although the Example of this invention was described, this invention is not limited to this,
As long as it does not deviate from the scope described in each claim, it is not limited to the wording of each claim, the scope is easily replaced by those skilled in the art, and improvements based on the knowledge that those skilled in the art normally have are made as appropriate. Can be added.

For example, in each of the embodiments described above, the change start frequency of the first special symbol is changed by changing the change time of both the first special symbol and the second special symbol during the opening time extension function operation. However, the present invention is not limited to this, and the change start frequency of the first special symbol may be changed by changing only the change time of the first special symbol or only the change time of the second special symbol. .
That is, by changing the variation time of at least one of the first special symbol and the second special symbol,
What is necessary is just to comprise so that the fluctuation | variation start frequency of a 1st special symbol may be fluctuated.

In the first embodiment, after the start of the opening time variation function, the number of variations of the special symbol is 5
When reaching 0 times, the change time of the special symbol is changed. In the second embodiment, after the start of the opening time change function, the change time of the special symbol is changed every time the special symbol is changed 20 times. In the third embodiment, after the start of the opening time variation function, the variation time of the special symbol is changed when the number of variations of the special symbol reaches 40 times and when it reaches 60 times. Although it comprised, the timing which changes the fluctuation time of a special symbol is not limited to these time points, It can set arbitrarily.

For example, in contrast to the second and third embodiments, as in the first embodiment, a special variation pattern (“first of the first embodiment”) is used when the first and second special symbol deviation variation pattern tables are changed. "Special pattern deviation variation pattern 2" or "Second special symbol variation pattern 3") is set, and the first and second special symbols are displayed during the variation display of the special symbol according to this special variation pattern. It is good also as performing the special production (change notification production) which shows the change opportunity of the change pattern table for detachment.

Further, in the second embodiment, after the start of the opening time variation function, the special symbol variation count 20
The special symbol variation time is extended step by step, but once the special symbol variation time is extended, the special symbol variation time is randomly shortened, extended or maintained. May be. For example, after the start of the opening time variation function, the number of variations of the special symbol is 1-2
The first and second special symbol deviation variation pattern table D (FIG. 11) is used in the case of 0 times, and the first and second special symbol deviation variation pattern table in the case of 21 to 40 variations in the special symbol. E (Fig. 11) is used, and after that, the number of changes in the special symbol every 20 times (the 40th change in the number of changes, 60
The first and second special symbol deviation variation pattern tables D to H (FIG. 11) may be switched to the first and second special patterns.

In this case, the first (fluctuation frequency 1 to 20) and second (fluctuation times 1 to 20) after the start of the opening time variation function
The first and second special symbol deviation variation pattern tables used for the variation count 21 to 40 are fixed in advance, and are third (variation count 41 to 60) and fourth (variation count 61 to 80).
Times), the first and second special symbol deviation variation pattern tables used for the fifth (number of variations 81 to 100 times) are randomly selected. The transition pattern of the variation pattern table for the first and second special symbol removal during the operation period of the opening time variation function is, for example, the first,
In “Random lottery for table change” using the table change random value acquired when the second special symbol deviation variation pattern table is changed, which special symbol deviation variation pattern table is to be changed. According to the determination result, a special pattern removal variation pattern table to be used next may be set, or based on the type of special symbol jackpot symbol that caused the opening time variation function to start. In accordance with the defined “table change order program”, a special pattern deviation variation pattern table to be used next may be set.

Further, in the second embodiment, after the start of the opening time variation function, the special symbol variation count 20
It is configured to extend both the first and second special symbol variation times step by step, but the first special symbol every time the special symbol variation count reaches the designated change count (for example, 10 times). And the second special symbol may be alternately selected as a special symbol to be extended and changed, and the variation time may be extended stepwise. For example, after the operation of the opening time variation function is started, when the number of variations of the special symbol is 1 to 10, the first special symbol deviation variation pattern table D (see FIG. 11) is applied to the first and second special symbols. Used, when the number of changes in the special symbol is 11 to 20, the first special symbol variation pattern table E (see FIG. 11) is used for the first special symbol, and the second special symbol is used. The second special symbol deviation variation pattern table D (see FIG. 11) is continuously used. Then, when the number of changes in the special symbol is 21 to 30, the first special symbol variation pattern pattern E (see FIG. 11) is continuously used for the first special symbol, and the second special symbol is used. For this, the second special symbol deviation variation pattern table E (see FIG. 11) is used. Thereafter, the deviation pattern table for detachment may be changed alternately for the first and second special symbols every 10th variation of the special symbol (the number of variations 40, 50,... 90). Thus, by alternately extending and changing the variation pattern tables of the first and second special symbols, it is possible to realize a game progress mode in which the variation display frequency of the second special symbols is gradually reduced.

In the first embodiment, the initial value of the variation pattern change counter is always set at the end of the big hit game. However, depending on the type of big hit symbol that triggered the big hit game, the initial value of the fluctuation pattern change counter is set. Depending on the type of jackpot symbol that triggered the start of the jackpot game, the initial value of the variation pattern change counter is set to a plurality of types of initial values (for example, “100”, “80”, “50”). , “0”, etc.). In this case, since the game period from the start of the opening extension function operation to the occurrence of the “special figure 1 suppression mode” can be set in various ways, the above-described game characteristics can be realized more effectively.
