Abstract

PROBLEM TO BE SOLVED: To provide a new playability and improve game amusement in a game machine provided with a short period win game with a short execution period.SOLUTION: When a special symbol variably displayed upon the entrance of a game ball to a start port brought into an open state by stopping and displaying a normal symbol by a win mode, either of a long period win game and a short period win game with an execution period shorter than the long period win game is executed. In the game machine which generates a high probability state in which the probability of stopping and displaying the special symbol by the win symbol is raised, a variation time shortening state in which the variation time of the normal symbol is shortened, and an open time extending state in which the open time of the start port is extended after the termination of the win game, the short period win game is executed when all of the high probability state, the variation time shortening state and the open time extending state are generated. When the short period win game is terminated, a special variation state in which the variation time of the normal symbol is further shortened compared with the variation time shortening state is generated.

Description

  The present invention relates to a gaming machine, and more particularly to a pachinko gaming machine.

  Many pachinko machines have a probability variation function that improves the probability that a special symbol stops and displays with a combination of jackpot symbols after the jackpot game ends. This type of gaming machine has a gameability that shifts to a state (probability change state) in which the probability variation function is activated after a big hit game (for example, 2R big hit game) in which the opening time of the big prize opening is short. There is a game with a gameability called “sudden probability change”. In addition, a small hit game that opens and closes the big prize opening in the same manner as a big hit game that creates “sudden probability change” (for example, 2R probability change big hit game), and after the small hit game ends, There is also a game with a game that maintains the operating state at the start of the small hit game. In this case, if the probability varying function is activated at the start of the small hit game, the probability varying function is activated even after the small hit game is finished.

  In a game machine equipped with such a big hit game and a small hit game in which the opening time of such a big prize opening is short, those hit games (games per short period) are when the probability variation function is not activated (in normal games) Occurs, it becomes difficult for the player to determine whether or not the probability variation function is activated after the end of the game, and as a result, expectation for the operation of the probability variation function is expected. A player can have a feeling (see, for example, Patent Document 1).

JP 2008-111954 A

  However, since the “game per short period” has a short execution period, it is common to be “game without hitting” with very few prize balls that can be obtained, and such a win game is low in value for the player. It will be a thing. For this reason, even if a `` game per short period '' is performed during the operation of the probability variation function, assuming that the operation of the probability variation function is continued, there is no merit for the player, and there are many prize balls that can be acquired for a long execution period. For a player who desires a long-term game (for example, a 15R big game), the game per short-term game may be perceived as an “annoying hit”, which may lead to a decrease in the game interest.

  In view of the above, an object of the present invention is to provide a new gaming property and improve a gaming interest in a gaming machine having a short-term game with a short execution period.

In order to achieve the above object, the gaming machine of the present invention provides:
A passing gate through which game balls can pass,
A normal symbol game execution means for displaying the normal symbol on the normal symbol display unit in response to the passage of the game ball through the passing gate until the predetermined normal symbol variation time has elapsed, and then stopping the normal symbol game execution means;
It is possible to switch between a normal state in which a game ball is difficult to enter and an open state in which a game ball is easy to enter, and when the normal symbol variably displayed on the normal symbol display unit is stopped and displayed in a hit state, A starting opening that is open,
Special symbol game execution means for displaying the special symbol on the special symbol display unit variably until the predetermined special symbol variation time elapses, and then stopping the display after the game ball has entered the start opening.
When the special symbol is stopped and displayed in a winning manner on the special symbol display unit, one of the long-term game and the short-term game having a shorter execution period than the long-term game is executed. Winning game execution means,
Probability changing means for generating a high probability state in which the probability that the special symbol is stopped and displayed in a winning manner after the winning game is finished is higher than usual.
Fluctuation time shortening means for generating a variation time shortening state in which the normal symbol variation time is shortened compared to normal after completion of the hit game,
An opening time extension means for generating an opening time extension state in which the opening time in which the start port is in the opening state is extended compared to a normal state after the winning game is ended;
When the game per short period is executed in a state where all of the probability variation means, the variation time shortening means, and the opening time extension means are operating, the normal symbol variation time after completion of the game per short period Special fluctuation means for generating a special fluctuation state that is shortened compared to the fluctuation time reduction state,
It is characterized by having.

  According to the gaming machine of the present invention having such a configuration, when all of the probability changing means, the changing time shortening means, and the opening time extending means are in operation, the “short period” on the assumption that these states are continued. When “winning” occurs, the fluctuation time of the normal symbol is further shortened after the game per short period resulting from the short period. As a result, the execution frequency of the normal symbol game, that is, the frequency of obtaining the result of the normal symbol game is further improved compared to before the occurrence of “per short period”, and the frequency at which the start port is opened is further improved. Become. As a result, the frequency of game balls entering the starting port is further improved, and the next hit can be generated earlier. Thus, the occurrence of “per short period” in the state where all of the probability variation means, the fluctuation time shortening means, and the open time extension means are operated, thereby making the game smoother than before “per short period”. A new game value that can be advanced can be given.

  Note that “winning game” refers to a game that allows a player to be given a predetermined benefit that is advantageous to the player compared to a game before the winning game occurs (for example, a symbol variation game). Specifically, it is possible to exemplify a game in which a winning opening (for example, a big winning opening) in a closed state in which a gaming ball cannot be entered normally is changed to an open state in which a gaming ball can enter. “Per game for a long period of time” refers to a hit game in which the benefits granted to the player are increased by increasing the execution time of the hit game. Specifically, the game changes from the above-mentioned closed state to the open state. An example is a game in which the opening time of a winning opening (for example, a big winning opening) is set to a time when the possibility of paying out a winning ball accompanying the entering of a gaming ball into the winning port becomes extremely high. Such a hit game is positioned as a “game with a ball exit” that makes it easy to obtain a large number of prize balls. On the other hand, the “game per short period” refers to a per game where the bonus granted to the player is reduced by shortening the execution time of the hit game. Specifically, the game changes from the above-mentioned closed state to the open state. An example is a game in which the opening time of a winning opening (for example, a big winning opening) is set to a time at which the possibility of paying out a winning ball accompanying the entering of a gaming ball into the winning port becomes extremely low. Such a winning game is positioned as a “game without hitting a ball” where it is difficult to obtain a large number of prize balls.

In addition, the gaming machine of the present invention,
The variation time shortening means generates a state in which the normal symbol variation time is shortened compared to normal and the special symbol variation time is shortened compared to normal as the variation time shortening state,
The special variation means generates, as the special variation state, a state in which the normal symbol variation time is shortened compared to the variation time shortened state and the special symbol variation time is shortened compared to the variation time shortened state. It is characterized by.

  In this way, the occurrence of “per short period” when all of the probability variation means, the variation time shortening means, and the open time extension means are in operation, so that not only the regular symbol variation time but also the special symbol The fluctuation time is further shortened compared to before “per short period”. As a result, not only the regular symbol game execution frequency but also the special symbol game execution frequency is further improved compared to before the occurrence of “per short period”, so that the game is smoother than before the occurrence of “per short period”. It becomes possible to proceed, and the next hit can be generated earlier.

In addition, the gaming machine of the present invention,
As a variation pattern table for determining a variation pattern that defines the special symbol variation time, a first variation pattern including a long-term variation pattern and a short-term variation pattern in which the special symbol variation time is shorter than the long-term variation pattern. A variation pattern table storage means for storing a table and a second variation pattern table in which the proportion of the short-term variation pattern is higher than that of the first variation pattern table;
Variation pattern determining means for determining a variation pattern of the special symbol using any one of the plurality of variation pattern tables stored in the variation pattern table storage means,
The variation pattern determining means includes
When all of the probability variation means, the variation time shortening means, and the open time extension means are activated, the variation pattern of the special symbol is determined using the first variation pattern table, and when the special variation means is activated, The variation pattern of the special symbol is determined using a second variation pattern table.

  Thus, by providing two types of variation pattern tables with different proportions of short-term variation patterns and using the second variation pattern table with a high proportion of short-term variation patterns after the end of the game per short period, It is possible to improve the variation frequency of the special symbol after the winning game is finished.

  According to the above-described configuration of the present invention, in a gaming machine that executes a game per short period of time that is short in execution time, it is possible to provide a new game and improve the game entertainment.

  The first starting port 28a is configured as a fixed starting port in which the size of the game ball receiving port does not change and the possibility of entering the game ball is constant, so that the game ball can always enter the game. It has become. On the other hand, the second start port 28b is a so-called tulip type and has a pair of wing pieces on the left and right, and the upper end gap between the pair of wing pieces serves as a game ball receiving port. The pair of wing pieces are each opened and closed by tilting in the left-right direction. With this opening and closing action, the second start port 28b is the size of the game ball receiving port of the pair of wing pieces. It is configured as a variable starter that changes. The second start port 28b is in an open state with a high probability of entering by opening a pair of blade pieces, and in a normal state with a low possibility of entering by closing a pair of blade pieces (incoming balls) Including an impossible closed state). When the normal symbol is stopped and displayed as a combination of symbols, the pair of wing pieces are opened to expand the game ball receiving port of the second start port 28b, and the second start port 28b is a normal electric accessory. Function as.

  Inside the start port 28, there are a start port entrance detection switch 28s (see FIG. 5) for detecting the entrance of a game ball into the first start port 28a, and the entrance of the game ball into the second start port 28b. A start opening ball detection switch 28t (see FIG. 5) for detection and a start opening solenoid 28c (see FIG. 5) for operating the pair of blade pieces are provided. When the pair of wing pieces are opened to the left and right, the size of the game ball receiving port of the second start port 28b is enlarged from the normal time, and the second start port 28b has a possibility of entering a game ball. It becomes an open state that becomes larger. On the other hand, when the pair of wing pieces are erected, the size of the game ball receiving port of the second start port 28b is slightly larger than the diameter of the game ball (one game ball can pass). The second start port 28b is in a normal state (closed state) in which the possibility of entering a game ball is reduced (or entry is impossible). When a game ball enters one of the start ports 28a, 28b, a special symbol described later starts to fluctuate.

  The big prize device 33 is disposed below the start port 28. Here, the special winning device 33 includes a special winning opening 33a opened in a belt shape, an opening / closing plate 33b for opening / closing the special winning opening 33a, and a large winning opening solenoid 33c (for operating the opening / closing plate 33b). 5) and an incoming ball detection switch 33s (see FIG. 5) for detecting an incoming game ball.

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

  The normal symbol display part 51 is comprised from one LED, and a normal symbol is displayed by this LED. In the normal symbol display unit 51, the normal symbol variation display and stop display are performed. In the normal symbol display unit 51, the normal symbol starts to change when the game ball passes through the normal symbol operating gate 27, and after a predetermined time has passed, the normal symbol hits and stops display in the normal symbol display mode or the dismissed normal symbol display mode. Is done. When the normal symbol is stopped and displayed in the preset normal symbol display mode, the second start port 28b is opened according to a predetermined opening pattern. A plurality of opening patterns of the second start port 28b are set. When the opening time extending function for extending the opening time of the second start port 28b is not in operation (normal time), a first opening pattern (short-time opening pattern) in which a first opening time (for example, 0.5 seconds) is set. ) Is set, and when the open time extension function is activated, a second open pattern (long open pattern) in which a second open time (for example, 4 seconds) longer than the first open time is set is set. The open time extension function will be described later.

  In the present embodiment, the normal symbol variation time (30 seconds in the present embodiment) and the shortened variation variation time (2 seconds in the present embodiment) shorter than the normal variation variation time are provided as the normal symbol variation time. It has been. Then, when the normal symbol success / failure determination is executed, a specific variation time is set according to the gaming state. Specifically, the fluctuation time for shortening fluctuation (2 seconds) is set during the operation of the fluctuation time reduction function, and the normal fluctuation time (30 seconds) is selected while the fluctuation time reduction function is not in operation. Is done. The variable time shortening function will be described later.

  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 a display mode (a hit mode) of the normal symbol. On the other hand, when it is determined to be out (when the acquired random number for normal symbol success / failure determination does not match the winning value), the normal symbol that is stopped and displayed in the normal symbol display unit 51 is out of the normal symbol display mode (exclusion Aspect).

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

  It should be noted that the determination of whether or not the normal symbol is determined, the determination of the stop symbol of the normal symbol, the setting of the variation time 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. Therefore, the main control unit 200 corresponds to the normal symbol game executing means and the special changing means of the present invention.

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

  In the first special symbol display unit 61, when the game ball enters the first starting port 28a, the first special symbol starts to fluctuate, and the first special symbol is a big hit symbol, a small hit symbol, or a missed symbol after a predetermined time has elapsed. In the second special symbol display section 62, the second special symbol starts to fluctuate when a game ball enters the second starting port 28b, and the second special symbol is a big hit after a predetermined time has elapsed. The display is stopped for any of the symbols, the small hit symbol, or the off symbol. 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. The first special symbol display unit 61 and the second special symbol display unit 62 correspond to the special symbol display unit of the present invention.

  In the present embodiment, the first special symbol random number acquired when the game ball enters the first start port 28a and the second special random number acquired when the game ball enters the second start port 28b. Design random numbers are provided. The first special symbol random number includes a first special symbol success / failure random number used for determining whether or not a big hit game or a small hit game (special game) is executed, and the first special symbol random number. A first special symbol determination random number for determining a stop symbol and a reach random number for determining whether or not to perform reach production are included. Similarly, the second special symbol random number for second special symbol success / failure determination used for the second special symbol success / failure determination of whether or not to execute the big hit game or the small hit game (special game), and the second A second special symbol determining random number for determining the stop symbol of the special symbol and a reach random number for determining whether or not to perform the reach effect are included.

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

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

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

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

  In the special symbol success / failure determination random number, a winning / decision hit value (big hit value and small hit value) is set, and is acquired at the timing when the game ball enters the first start port 28a or the second start port 28b. When the special symbol success / failure determination random number coincides with the big hit value, it is judged as a big hit, and when it does not coincide with the big hit value and coincides with the small hit value, it is judged as a big hit. The first special symbol success / failure determination is performed when the first special symbol starts variable display, and the second special symbol correctness determination is performed when the second special symbol starts variable display.

  When the first special symbol success / failure determination random number matches the jackpot value, it is determined that the jackpot value is determined, and the first special symbol that is stopped and displayed on the first special symbol display unit 61 is determined as the jackpot symbol. Further, when the first special symbol success / failure determination random number matches the small hit value, it is determined as a small hit, and the first special symbol stopped and displayed on the first special symbol display unit 61 is determined as the small hit symbol. When the first special symbol success / failure determination random number does not coincide with either the big hit value or the small hit value, the first special symbol displayed on the first special symbol display unit 61 is displayed as a lost symbol. It is determined.

  Similarly, when the second special symbol success / failure determination random number coincides with the jackpot value, the jackpot is determined, and the second special symbol stopped and displayed on the second special symbol display unit 62 is determined as the jackpot symbol. Further, when the second special symbol success / failure determination random number coincides with the small hit value, it is determined as a small hit, and the second special symbol stopped and displayed on the second special symbol display unit 62 is determined as the small hit symbol. If the second special symbol success / failure determination random number does not coincide with either the big hit value or the small hit value, the second special symbol that is stopped and displayed on the second special symbol display unit 62 is lost. To be determined.

  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 special symbol variation pattern is selected by lottery using a variation pattern random number from a variation pattern table in which a plurality of variation patterns are stored when the special symbol success / failure determination is executed.

  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). In these multiple variation pattern tables, “High probability shortening” is selected in the high probability shortening variation state (high probability shortening variation mode) in which all of the probability variation function, variation time shortening function, and open time extension function are operating. Only the fluctuation pattern table A ”, the“ high probability reduction fluctuation pattern table B ”selected when the special fluctuation period is set in the high probability reduction fluctuation state (high probability reduction fluctuation mode), and the probability fluctuation function only operate. "High probability normal fluctuation pattern table" selected in the high probability normal fluctuation state (high probability normal fluctuation mode), and the probability fluctuation function does not work and the fluctuation time shortening function and the open time extension function are working Neither the “low probability shortening variation pattern table” selected in the low probability shortening variation state nor the probability variation function, variation time shortening function, or open time extension function is operating. Low probability normal variation state contains "low probability normal variation pattern table" to be selected (low probability normal variation mode). These variation pattern tables are stored in the ROM of the main control unit 200, and the main control unit 200 corresponds to the variation pattern table storage means of the present invention.

  In addition, each variation pattern table selected according to the gaming state is different from the hit variation pattern table selected when the special symbol success / failure determination result is a hit (big hit or small hit) and the special symbol success / failure determination result. And a deviation variation pattern table selected in this case. The deviation variation patterns stored in the deviation variation pattern table include a “normal deviation variation pattern (reach variation pattern without reach)” that does not involve reach variation and a “reach variation pattern with reach” that involves reach variation. The normal deviation variation pattern is configured as a “short-term variation pattern” with a short special symbol variation time, and the reach deviation variation pattern is configured as a “long-term variation pattern” with a special symbol variation time. . The presence or absence of reach variation is determined by lottery using a reach random number acquired when the game ball enters the start port 28.

  Here, the high probability shortening variation pattern table A selected in the high probability shortening variation mode and the high probability shortening variation pattern table B selected in the special variation mode will be described with reference to FIGS. FIG. 3 shows a specific example of a variation pattern table used when the result of the special symbol success / failure determination is a win (big hit or small hit), and FIG. 4 shows the variation used when the result of the special symbol success / failure determination is wrong. A specific example of the pattern table is shown.

  When the probability variation big hit game ends and the game mode shifts to the high probability shortening variation mode (when the probability variation game is started), the use of the high probability shortening variation pattern table A is started. Then, in the high probability shortening variation mode, a game per short period (2R probability variable big hit game, small hit game) is played, and if the game per short period (2R probability variable big hit game, small hit game) ends, a high probability The special variation period is started in a state where the shortened variation mode is maintained, and the special variation mode in which the high probability shortened variation pattern table B is used is started. The high probability shortening variation pattern table B is positioned as a special variation pattern table used in a special variation period (special variation mode). After the end of the special fluctuation period, the high probability shortening fluctuation pattern table A is used again. The high probability shortening variation pattern table A corresponds to the first variation pattern table of the present invention, and the high probability shortening variation pattern table B corresponds to the second variation pattern table of the present invention. The “game per short period” will be described later.

  In the high probability shortening variation pattern table A and the high probability shortening variation pattern table B, the long term variation pattern table (FIG. 3) selected when the result of the special symbol success / failure determination is “first big hit (per long term)”. (A)), a special symbol success / failure pattern table (FIG. 3 (b)) selected when the result of the special symbol success / failure determination is “second big hit or small hit (per short term)”, and special symbol success / failure Each includes a deviation variation pattern table (FIG. 4A, FIG. 4B) selected when the determination result is deviation. The high probability shortening variation pattern table A and the high probability shortening variation pattern table B are common to the long term variation pattern table (FIG. 3 (a)) and the short term variation pattern table (FIG. 3 (b)). Only the deviation variation table (FIGS. 4A and 4B) is different. The first big hit, the second big hit, and the small hit will be described later.

  FIG. 3A shows a long-term variation pattern table included in the high probability shortening variation pattern table A and the high probability shortening variation pattern table B. The long-term variation pattern table includes five types of variation patterns A to E. These hit variation patterns A to E are all variation patterns with reach variation, and the variation times of special symbols are different from each other. Further, each variation pattern A to E included in the long-term variation pattern table is a variation pattern random number (0 to 255) acquired when the game ball enters the start port 28 regardless of the number of special symbols held. Selected based on Specifically, when the fluctuation pattern random number is “0 to 50”, “hit fluctuation pattern A (fluctuation time 100 seconds)” is selected, and when the fluctuation pattern random number is “51 to 100”, “hit fluctuation pattern B”. (Variation time 130 seconds) ”is selected, and when the variation pattern random number is“ 101 to 150 ”,“ hit variation pattern C (variation time 125 seconds) ”is selected and variation pattern random number is“ 151 to 200 ” “Hit fluctuation pattern D (fluctuation time 150 seconds)” is selected, and when the fluctuation pattern random number is “201 to 250”, “hit fluctuation pattern E (fluctuation time 120 seconds)” is selected.

  FIG. 3B shows a short period variation pattern table included in the high probability shortening variation pattern table A and the high probability shortening variation pattern table B. The short period fluctuation pattern table includes two types of hit fluctuation patterns F and G. These hit variation patterns F and G are all variation patterns with reach variation, and the variation times are different. Further, each variation pattern F, G included in the variation pattern table per short period is selected based on a variation pattern random number (0-255) regardless of the number of special symbol reservations. Specifically, when the fluctuation pattern random number is “0 to 123”, “hit fluctuation pattern F (fluctuation time 100 seconds)” is selected, and when the fluctuation pattern random number is “124 to 255”, “hit fluctuation pattern G”. (Variation time 120 seconds) "is selected.

  FIG. 4A shows a deviation fluctuation pattern table A included in the high probability shortening fluctuation pattern table A. FIG. In the deviation variation pattern table A, two types of variation patterns of normal deviation variation patterns A and B are set as variation patterns without reach (short-term variation patterns). In addition, the deviation variation pattern table A includes five types of reach variation patterns (long-term variation patterns) including normal reach deviation variation patterns A and B, normal long reach deviation variation patterns, and super reach deviation variation patterns A and B. A fluctuation pattern is set.

  When it is determined that the reach variation pattern table A does not perform reach variation by the reach random number, the variation pattern is selected by the special symbol holding number regardless of the value of the variation pattern random number. Specifically, when the number of special symbol hold is “1”, the normal deviation fluctuation pattern A (fluctuation time 10 seconds) is selected, and when the number of special symbol hold is “2-4”, it is normally off. A variation pattern B (a variation time of 3 seconds) is selected.

  On the other hand, when it is determined that the reach fluctuation pattern table A is subjected to reach fluctuation by the reach random number, the fluctuation pattern is selected based on the value of the fluctuation pattern random number and the number of special symbol reservations. Specifically, when the special symbol hold number is “1” or “2” and the fluctuation pattern random number is “0 to 99”, “normal reach deviation fluctuation pattern A (fluctuation time 20 seconds)” is selected, When the variation pattern random number is “100 to 150”, “normal long reach deviation variation pattern (variation time 40 seconds)” is selected, and when the variation pattern random number is “151 to 220”, “super reach deviation variation pattern A ( “Variation time 90 seconds)” is selected, and when the variation pattern random number is “221 to 255”, “super-reaching variation pattern B (variation time 120 seconds)” is selected. In addition, when the special symbol hold number is “3” or “4” and the variation pattern random number is “0 to 150”, “normal reach deviation variation pattern B (variation time 15 seconds)” is selected, and the variation pattern random number Is “151 to 240”, “super-reaching deviation variation pattern A (variation time 90 seconds)” is selected, and when the variation pattern random number is “241 to 255”, “super-reaching deviation variation pattern B (variation time 120). Second) "is selected.

  FIG. 4B shows a deviation variation pattern table B included in the high probability shortening variation pattern table B. In the deviation variation pattern table B, only two types of variation patterns without reach (short-term variation patterns) of normal deviation variation patterns C and D are set. In the deviation variation pattern table B, the variation pattern is selected according to the number of special symbol reservations regardless of the value of the variation pattern random number. Specifically, when the number of special symbol hold is “1”, the normal deviation fluctuation pattern C (fluctuation time 5 seconds) is selected, and when the number of special symbol hold is “2-4”, it is normally off. A variation pattern D (a variation time of 1 second) is selected.

  FIG. 4C shows a deviation variation pattern table included in the low probability normal variation pattern table for comparison. The out-of-range variation pattern table of the low probability normal variation pattern table includes a normal out-of-range variation pattern E (variation time of 15 seconds), a normal out-of-range variation pattern F (variation time of 10 seconds), and a normal out-of-range variation pattern G ( 3 types of fluctuation patterns (variation time 5 seconds) are set, and five kinds of fluctuations common to the outlier fluctuation pattern table A (FIG. 4A) of the high probability shortening fluctuation pattern table A as the fluctuation patterns with reach. A pattern is set. The normal deviation fluctuation patterns A to D (FIGS. 4A and 4B) included in the above-described high probability shortening fluctuation patterns A and B (outgoing fluctuation pattern tables A and B) are low probability normal fluctuation pattern tables. Compared to the normal deviation fluctuation patterns E to G (FIG. 4C) included in the deviation deviation pattern table, the average fluctuation time of the special symbol is configured as a shortened fluctuation pattern.

  As described above, the outlier fluctuation pattern table A of the high probability shortening fluctuation pattern A and the outlier fluctuation pattern table B of the high probability shortening fluctuation pattern B are the normal outlier fluctuation pattern (short-time fluctuation pattern) and the outlier fluctuation pattern with reach. The ratio of (long-time variation pattern) is different. Specifically, the deviation variation pattern table B has a higher ratio of the normal variation pattern (short-time variation pattern) than the deviation variation pattern table A (100% in this embodiment). For this reason, when the high probability shortening variation pattern table B (outlier variation pattern table B) is set, the special symbol is changed more than when the high probability shortening variation pattern table A (outlier variation pattern table A) is set. The average fluctuation time is shortened, and the frequency of executing the special symbol fluctuation display is increased. Furthermore, in this embodiment, the normal deviation fluctuation patterns A and B (FIG. 4A) included in the deviation fluctuation pattern table A are compared with the normal deviation fluctuation patterns C and D (FIG. Since the variation time of the special symbol is shorter in b)), when the high probability shortening variation pattern table B (outlier variation pattern table B) is set, the high probability shortening variation pattern table A (outlier variation pattern table). The average variation time of the special symbol is shorter than when A) is set.

  For this reason, when the probability variation big hit game ends and the game mode shifts to the high probability shortening variation mode (when the probability variation game is started), the use of the high probability shortening variation pattern table A is started, The variation time of the special symbol is shortened, and the execution frequency of the special symbol is improved. Further, in the high probability shortening variation state, a short-term game (2R probability variation big hit game, small hit game) is started, and when the short term game ends, use of the high probability shortening variation pattern table B is started. As a result, the variation time of the special symbol is further shortened, and the execution frequency of the special symbol is further improved.

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.

  First special symbol success / failure determination, second special symbol success / failure determination, determination of variation mode (variation pattern) of first special symbol, determination of variation mode (variation pattern) of second special symbol, stop of first special symbol Determination of symbol, determination of stop symbol of second special symbol, change display and stop display of first special symbol, change display and stop display of second special symbol, priority change of second special symbol will be described later. 200. Therefore, the main control unit 200 corresponds to the special symbol game execution means, special fluctuation means, and fluctuation pattern determination means of the present invention.

  Next, the jackpot game (special game) will be described. When the special symbol stopped and displayed on the first special symbol display unit 61 or the second special symbol display unit 62 is the above-mentioned jackpot symbol (when the result of the special symbol success / failure determination is a big hit), the main control unit 200 Starts a big hit game (special game) that is relatively advantageous to the player. The big hit game is started by setting the big hit game flag to ON, and the big winning device 33 is operated, in other words, the big winning opening 33a is opened and closed a plurality of times, so that the game balls to the big winning opening 33a are opened. It gives a player a profit (prize ball) for entering the ball. The big hit game is realized by repeatedly executing a hit game process by the main control unit 200 described later, and the main control unit 200 corresponds to the big hit game execution 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, when the opening time of the big winning opening 33a reaches a specified time (in this embodiment, 0.2 seconds or 26 seconds), or the number of game balls that have entered the opened big winning opening 33a is It may be when the specified number (10 in this embodiment) is reached.

  In the case where one round game is performed from the start to the end of the open state of the big winning opening 33a, the big hit game is ended when a predetermined number of round games are performed. In the grand prize winning device 33, after the special prize opening 33a has been opened, that is, after a predetermined time has elapsed since the big prize winning opening 33a is closed, the big prize winning opening 33a is again opened and the next round game starts. To do. The opening / closing operation of the grand prize winning port 33a in which one round game is from the opening start to the end of the big cash winning opening 33a is repeatedly continued until the predetermined maximum number of consecutive rounds is completed.

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

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

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

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

  In the gaming machine of the present embodiment, after the big hit game is finished, a specific game (so-called short-time game and probability variable game) in which the variable time shortening function, the open time extending function and the probability varying function are activated is started. 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 1 of this embodiment, when the result of the special symbol success / failure determination is a big hit and the stop symbol of the special symbol is the first normal big hit symbol (the big hit type is the first normal big hit), the big hit game ends. Thereafter, the variable time shortening function and the opening time extending function for extending the opening time of the second start port 28b start to operate, and the time-saving game is started. The short-time game (operation of the variable time reduction function and the opening time extension function) is realized by the control of the main control unit 200, which will be described later, and the variable time reduction function is a common technique for reducing the fluctuation time of a normal symbol. A variation time shortening function and a special diagram variation time shortening function for shortening the variation time of the special symbol are included. By the activation of the opening time extension function, the opening time of the second start port 28b is extended from the first opening time (for example, 0.5 seconds) to the second opening time (for example, 4 seconds). As a result, the frequency of entering the game ball into the second start port 28b is higher than that at normal time (when the opening extension function is not activated). As described above, the special symbol (the first special symbol) is shortened by the operation of the variable time shortening function and the opening time of the second start port 28b is extended by the activation of the open time extending function. The variation frequency of the symbol and the second special symbol is improved. In this embodiment, the fluctuation time shortening function and the opening time extension function are terminated when the number of times the special symbol changes reaches “100 times” without starting the next big hit game after the big hit game ends. .

  When the result of the special symbol success / failure determination is a big hit, and the stop symbol of the special symbol is the first probability variation big hit symbol (the big hit type is the first positive variation big hit) or the second probability variable big hit symbol (the big hit type is the second positive variation big hit) After the big hit game is finished, in addition to the fluctuation time shortening function and the opening time extension function, the probability fluctuation function starts to operate, and the probability variation game is started. The probability variation game is realized by the control of the main control unit 200. In this probability variation game, the probability that the result of the special symbol success / failure determination is a big hit, that is, the probability that the special symbol is stopped and displayed with the big hit symbol is changed (improved). The probability variation function (special symbol probability variation means) is activated.

  While the probability variation function is in operation, the probability that the result of the special symbol success / failure determination is a jackpot is improved by increasing the jackpot value for the determination of success / failure. Specifically, a normal probability success / failure determination table and a high probability success / failure determination table in which the number (type) of jackpot values is larger than the normal probability success / failure determination table are prepared. During normal games (when the probability variation function is inactive), the normal probability determination table is used to determine whether or not, and during probability change games (when the probability variation function is in operation), a high probability determination table is used. Make a pass / fail decision.

  The probability variation function operates after the jackpot game is over until the next jackpot game is started. In this embodiment, the maximum execution period of the probability variation game is set until the number of fluctuations of the special symbol after the big hit game reaches 10,000 times until the next big hit game is substantially started. . If the variable time reduction function and the open time extension function are also activated during the probability variable game execution period (the operation period of the probability variable function), the operation period of the variable time reduction function and the open time extension function is also the jackpot game. It is set until the number of fluctuations of the special symbol after the end reaches 10,000 times. The fluctuation time shortening function, the open time extension function, and the probability fluctuation function are realized by the control of the main control unit 200. Therefore, the main control unit 200 corresponds to the probability changing means, the changing time shortening means, and the open time extending means of the present invention.

  If the result of the special symbol success / failure determination is a big hit and the stop symbol of the special symbol is determined to be the second probability variable big hit symbol (in the case of the second probability variable big hit), the second big hit game starts (the second probability variable big hit symbol is The operating state of the variable time shortening function and the open time extending function when the stop is displayed is maintained. That is, when the variation time shortening function and the opening time extension function are activated at the start of the second big hit game, the variation time shortening function and the opening time extension function are activated even after the second big hit game is finished. On the other hand, when the variation time shortening function and the opening time extension function are not activated at the start of the second big hit game, the variation time shortening function and the opening time extension function are not activated even after the second big hit game is finished.

  Here, the game mode (game state) after the end of the hit game (big hit game and small hit game) is distinguished depending on whether or not the probability variation function, the variation time shortening function, and the open time extension function are activated. Specifically, the above-mentioned probability variation function, variation time shortening function, open time extension function all high probability shortening variation mode, probability probability variation function only high probability normal variation of each function Mode, low probability shortening variation mode in which open time extension function and variation time shortening function are activated, low probability normal variation mode in which each function is not activated, special probability period in high probability shortening variation mode The game mode is classified into five game modes such as a special variation mode in which is set. These game modes all correspond to the special symbol fluctuation mode, and are described above in the high probability shortening variation mode, special variation mode, high probability normal variation mode, low probability shortening variation mode and low probability normal variation mode, respectively. Using the “high probability shortening variation pattern table A”, “high probability shortening variation pattern table B”, “high probability normal variation pattern table”, “low probability shortening variation pattern table” and “low probability normal variation pattern table” A variation pattern of the special symbol is determined.

  Next, the small hit game will be described. When the special symbol stopped and displayed on the first special symbol display unit 61 or the second special symbol display unit 62 is a small hit symbol (when the result of the special symbol determination is a small hit), the main control unit 200 Starts a small hit game.

  The small hit game is a hit game that is started by setting the small hit game flag to ON, and constitutes a “short game per game” together with the second big hit game. In the small hit game, the big prize device 33 operates in the same manner as the second big hit game described above. In other words, in the small hit game, the large winning opening 33a is configured to be opened twice for 0.2 seconds, and the possibility that a game ball enters the large winning opening 33a is very low, so that the payout of the winning ball is substantially reduced. It is in a gaming state that does not accompany. In addition, after the small hit game ends, the operating state of the open time extension function when the small hit game is generated (when the small hit symbol is stopped and displayed) is maintained.

  In the small hit game, since the operation of the second big hit game and the big prize device 33 is the same mode, the player can open and close the big winning opening 33a twice in a short time (a big winning opening opening pattern in the second big hit game) ) Cannot be discriminated whether the second big hit game or the small hit game has occurred. For this reason, it is possible to make it more difficult to recognize whether or not the probability varying function is activated after the operation of the big winning device 33 is finished (after the second big hit game or the small hit game is finished). Thus, the state in which the player has difficulty in recognizing (difficult to determine) that the probability variation function is operating is referred to as “probability non-notification state” or “latent probability variation state (internal probability variation state)”.

  As described above, the first jackpot game is a “long-term game” with a long execution period, and a predetermined number (10) of balls entered into the big winning opening 33a and the possibility of executing a prize ball payout associated therewith. It is extremely high, and it is positioned as a “game with every ball” that allows a large number of prize balls to be acquired. On the other hand, the second big hit game and the small hit game are “games per short period” with a short execution period, and it is possible to execute a prescribed number (10) of balls to the big winning opening 33a and a prize ball payout associated therewith. It is positioned as a “game without hitting a ball” that is extremely low in performance and difficult to obtain a large number of prize balls. “Per game for a long period of time” is a win game for the purpose of acquiring a large amount of prize balls, whereas “Game for a short period of time” is a game of play for the purpose of shifting to a game mode or maintaining a game mode. But there is. In other words, after the end of the second probability variation big hit game, the probability variation function starts to operate (the game mode shifts) with respect to the game state at the start of the hit game, and after the end of the small hit game, the hit game starts. The operation state of the probability variation function, the variation time shortening function, and the open time extension function does not change with respect to the gaming state (game mode is maintained).

  In this embodiment, the winning probabilities for “long term (15R big hit)” and “short term (2R probability variation big hit, small hit)” are different in the first special symbol success / failure determination and the second special symbol success / failure determination. . Specifically, in the second special symbol success / failure determination, the winning probability per short period is low and the winning probability per long term is high compared to the first special symbol success / failure determination. As described above, since a prize ball is hardly obtained in a game per short period, a game per long period in which a large number of prize balls are obtained is more advantageous to the player than a game per short period. For this reason, the second special symbol success / failure determination having a low winning probability per long time is more advantageous to the player than the first special symbol success / failure determination having a high winning probability per short period, and a game ball is placed in the first start port 28a. It is more advantageous for the player to enter the game ball into the second start port 28b than to enter the ball.

  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. The effect symbol of the effect symbol display unit 25a is displayed in conjunction with the change display and stop display of the first special symbol of the first special symbol display unit 61 or the second special symbol of the second special symbol display unit 62.

  The effect symbol display unit 25a is composed of three symbol display areas including a left symbol display area where a left symbol is displayed, a middle symbol display area where a middle symbol is displayed, and a right symbol display area where a right symbol is displayed. 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 can display symbols consisting of “1” to “9”.

  When the first special symbol or the second special symbol is stopped and displayed in any of the symbols, the first symbol or the second special symbol is started. The special symbol or the second special symbol is stopped and displayed with a symbol corresponding to the stop symbol. In the effect symbol, the symbol combination with the same three digits corresponds to the special symbol long-term symbol (15R big hit symbol) (first symbol of the effect symbol), and the sequential combinations such as “1, 2, 3”, etc. Chance symbols (so-called chance eyes) that are predetermined specific symbols other than jackpot symbols, such as an odd number sequence such as “1, 3, 5” or an unreachable combination such as “7, 6, 7”, etc. Corresponds to symbols per short period (2R probability variation big hit symbol, small hit symbol) (second hit pattern of the effect symbol), other symbol combinations correspond to the special symbol out of symbol (effect symbol outage mode) ).

  The design pattern variation mode (variation pattern) and stop symbol determination are configured to be performed by the sub-control unit 260 based on a variation pattern designation command and a stop information designation command transmitted from the main control unit 200. Here, the variation pattern designation command transmitted from the main control unit 200 to the sub-control unit 260 indicates the variation pattern of the special symbol. Specifically, the variation time of the special symbol and the presence / absence of the reach effect The contents of the production are shown. The main control unit 200 determines a variation pattern of the special symbol at random (by random number lottery) according to the determination result of the special symbol. Based on the special symbol variation pattern determined by the main control unit 200, the sub-control unit 260 determines the effect pattern of the effect symbol displayed on the effect symbol display unit 25a. Further, the stop information designation command transmitted from the main control unit 200 to the sub-control unit 260 indicates a special symbol stop symbol, and the main control unit 200 determines whether the special symbol is determined according to the result of the special symbol determination. A stop symbol is determined at random (by random number lottery). Then, based on the stop information designation command indicating the stop symbol of the special symbol determined by the main control unit 200, the sub control unit 260 determines the stop symbol of the effect symbol to be stopped and displayed on the effect symbol display unit 25a.

  In the present embodiment, during the period from the start of the display of the effect symbol to the stop display until the stop display, various effects such as a background change effect, a notice effect, and a reach effect are displayed on the display area of the effect display device 25 (the effect symbol display unit 25a).

  Next, the operation of the gaming machine 1 of this embodiment will be described based on a flowchart. FIG. 6 is an example of a main job performed under the control of the main control unit 200. The main job shown in FIG. 6 is executed by the CPU 200b mounted on the main control board 200a in accordance with a program stored in a ROM (not shown) (an internal ROM of the CPU 200b or a ROM mounted on the main control board 200a). After the insertion process (S200), the game start process (S300), the normal symbol game process (S400), the special symbol game process (S500), and the winning game process (S600) are repeatedly executed each time the timer is reset. Is done. In the power-off process (S100), when a power-off occurs due to a power failure or the like, the used registers and stack pointers are saved, the payout motor is stopped, and the power-on process (S200) when a system reset occurs. It has come to move to.

  The power-on process (S200) is performed when the power is turned on and when the power is restored after the power is cut off. When the power is turned on, RAM initialization processing is performed, and when the power is turned off, the game state is restored when the power is turned off. Return settings etc. are made to make it happen. In the game start process (S300), detection of various switch states, update of various random numbers, prize ball payout control, and the like are performed.

  Next, the normal symbol game process (S400) will be described based on the flowchart of FIG. First, it is determined by the normal symbol operation gate detection switch 27s whether or not the game ball has passed the normal symbol operation gate 27 (S401). As a result, when it is determined that the game ball does not pass through the normal symbol operation gate 27 (S401: NO), the process proceeds to S404. On the other hand, when it is determined that the game ball has passed the normal symbol operation gate 27 (S401: YES), it is determined whether or not the normal symbol hold number is less than 4 (S402). As a result, when the number of normal symbol holds is 4 or more (S402: NO), the process proceeds to S404. On the other hand, if the number of normal symbol hold is less than 4 (S402: YES), a normal symbol success / failure determination random number is acquired and stored in a predetermined area of the RAM (S403). As a result, the number of normal symbol reservations increases by one.

  Next, it is determined whether or not the second start port 28b is open (S404). If it is determined that the second start port 28b is open (S404: YES), the process of S415 is performed. If it is determined that the second start port 28b is not open (S404: NO), it is determined whether or not the normal symbol is changing (S405). As a result, when it is determined that the normal symbol is changing (S405: YES), the process proceeds to S408. On the other hand, when it is determined that the normal symbol is not fluctuating (S405: NO), it is determined whether or not the normal symbol holding number is zero (S406).

  As a result, when it is determined that the number of normal symbol hold is zero (S406: YES), the normal symbol game process is terminated. On the other hand, when it is determined that the number of normal symbols held is not zero (S406: NO), normal symbol variation display related processing is performed (S408). Here, the normal symbol variation display process (S407) will be described based on the flowchart of FIG.

  First, the random number for normal symbol validity determination acquired and stored in the process of S403 is read from a predetermined area of the RAM (S407a), and the normal symbol validity determination is performed (S407b).

  Next, it is determined whether or not the determination result of the normal symbol appropriateness determination is a win (S407c). As a result, when it is determined that the determination result of the normal symbol determination is a win (S407c: YES), the winning symbol is set as the stop symbol of the normal symbol (S407d). On the other hand, when it is determined that the result of the normal symbol success / failure determination is not a hit (deletion) (S407c: NO), the out symbol is set as a stop symbol of the normal symbol (S407e).

  Next, it is determined whether or not the fluctuation shortening flag is set to ON (whether or not the fluctuation time shortening function is operating) (S407f). As a result, when it is determined that the variation shortening flag is set to ON (S407f: YES), the variation time for shortening variation (2 seconds in this embodiment) is set as the variation time of the normal symbol (S407g). ). On the other hand, if it is determined that the fluctuation shortening flag is not set to ON (S407f: NO), the fluctuation time for normal fluctuation (30 seconds in this embodiment) is set as the fluctuation time of the normal symbol (S407h). .

  Next, normal symbol variation display is started (S407i). Here, 1 is subtracted from the number of normal symbols held. The processing up to this point is to start the normal symbol variation display.

Next, returning to FIG. 7, if it is determined in the process of S405 that the normal symbol is changing (S405: YES), it is determined whether or not the normal symbol change time has elapsed (S408). If it is determined that the normal symbol variation time has not elapsed (S408: NO), the normal symbol game process is terminated. On the other hand, when it is determined that the variation time of the normal symbol has elapsed (S408: YES), the normal symbol stop display time is set and the normal symbol is stopped and displayed (S409). Here, the stop display time of the normal symbol is a time for determining the normal symbol stopped and displayed. In this embodiment, the stop display time of the normal symbol is “1 second”.

  Next, it is determined whether or not the normal symbol stop symbol is a winning symbol that activates (opens) the second start port 28b (S410). As a result, when it is determined that the stop symbol of the normal symbol is not a winning symbol (S410: NO), the normal symbol game process is terminated.

  On the other hand, if it is determined that the stop symbol of the normal symbol is a winning symbol (S410: YES), whether or not the release extension flag is set to ON (whether or not the release time extension function is activated). Is determined (S411). As a result, when the release extension flag is OFF (when the release time extension function is not activated) (S411: NO), the first release pattern (0. 5 seconds) is set (S412), and when the release extension flag is ON (when the release time extension function is activated) (S411: YES), the second opening pattern is set as the opening pattern of the second start port 28b. (4 seconds in this embodiment) is set (S413). Then, the opening operation of the second start port 28b is started (S414). As a result, the pair of blade pieces are opened left and right, and the second start port 28b is opened.

  Next, when it is determined in the determination process of S404 that the second start port 28b is being opened (S404: YES), it is determined whether or not the opening operation end condition for the second start port 28b is satisfied. Determination is made (S415). The “opening operation end condition of the second starting port 28b” is the case where the opening time of the second starting port 28b set in the processing in S412 or S413 has passed, or the second starting port 28b has received a predetermined number of winnings. The case holds.

  As a result, when it is determined that the condition for ending the opening operation of the second start port 28b is not satisfied (S415: NO), the normal symbol game process is ended. On the other hand, when it is determined that the condition for ending the opening operation of the second starting port 28b is satisfied (S415: YES), the opening operation of the second starting port 28b is ended and the second starting port 28b is closed (S416). ).

  Next, the special symbol game process (S500) will be described based on the flowcharts of FIGS. First, as shown in FIG. 9A, 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 been won (a game ball has entered) (S501a). If it is determined that the first start port 28a has not been won (S501a: NO). The process proceeds to S501d. On the other hand, if it is determined that the first start port 28a has been won (S501a: YES), it is determined whether or not the first special symbol hold number is less than 4 (S501b). As a result, when it is determined that the first special symbol reservation number is not less than 4 (4 or more) (S501b: NO), the process proceeds to S501d, and the first special symbol reservation number is less than 4. Is determined (S501b: YES), the first special symbol random number (first symbol success / failure determination information) is acquired and stored in a predetermined area of the RAM (S501c). The first special symbol random number includes a first special symbol determination random number, a first special symbol hit random number, a reach random number, and the like. Thereby, the 1st special symbol reservation number increases by one.

  Next, it is determined whether or not the second start port 28b has been won (S501d). If it is determined that the second start port 28b has not been won (S501d: NO). The start opening winning process is terminated. On the other hand, if it is determined that the second start port 28b has been won (S501d: YES), it is determined whether or not the second special symbol hold number is less than 4 (S501e). As a result, when it is determined that the second special symbol hold number is not less than 4 (4 or more) (S501e: NO), the start opening winning process is terminated, and the second special symbol hold number is less than 4. If it is determined that there is (S501e: YES), a second special symbol random number (second symbol success / failure determination information) is acquired and stored (S501f). The second special symbol random number includes a second special symbol determination random number, a second special symbol determination random number, a reach random number, and the like. Thereby, the number of second special symbol reservation increases by one.

  Next, returning to FIG. 9A, it is determined whether or not a winning game is being performed (whether the big hit game flag or the small hit game flag is ON) (S502). As a result, when it is determined that a hit game is being played (a big hit game flag or a small hit game flag is ON) (S502: YES), the special symbol game process is terminated and no hit game is being played (a big win game) If it is determined that the flag and the small hit game flag are OFF) (S502: NO), it is determined whether or not the 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). Then, 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 holding | maintenance number being zero (S507: YES), a special symbol game process is complete | finished. On the other hand, when it is determined that the number of first special symbol hold is not zero (S507: NO), a first special symbol variation display process is performed (S508).

  On the other hand, if it is determined in S506 that the second special symbol hold count is not zero (S506: NO), a second special symbol variation display process is performed (S509). That is, if it is determined in the determination process of S506 that the second special symbol hold number is not zero (S506: NO), the first special symbol hold number is not zero (even if it is 1 or more). 2. The special symbol variation display process 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 (S509) will be described based on the flowchart of FIG. The first special symbol variation display process and the second special symbol variation display process are processes having the same contents except that the portions of the “first special symbol” and the “second special symbol” are different. The symbol is “first special symbol” in the first special symbol variation display process, and “second special symbol” in the second special symbol variation display process. 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 random number for determining whether or not the special symbol is stored in a predetermined area (holding storage area) of the RAM of the main control unit 200 (the random number for determining whether or not the game ball has entered the start opening 28) is read (S508a). ), Special symbol winning / failing determination is performed (S508b). In the special symbol success / failure determination, if the probability variation function is operating (probability change game), the determination of success / failure 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 result of the special symbol success / failure determination (S508b) is a big hit (S508c). As a result, when it is determined that it is a big hit (S508c: YES), a big hit hour variation pattern table setting process is performed (S508d). On the other hand, when it is determined that it is not a big hit (S508c: NO), a small hit determination is further performed to determine whether or not the result is a small hit (S508e). As a result, when it is determined that the game is a small hit (S508e: YES), a small hit hour variation pattern table setting process is performed (S508f). On the other hand, when it is determined that it is not a small hit (S508e: NO), a variation pattern table setting process at the time of disconnection is performed (S508g).

  Here, the big hit fluctuation pattern table setting process (S508d), the small hit fluctuation pattern table setting process (S508f), and the lost fluctuation pattern table setting process (S508g) will be described with reference to the flowchart of FIG. Since each variation pattern table distribution process (S508d, S508f, S508g) is a process having the same contents, common processes in each variation pattern table distribution process will be described.

  As shown in FIG. 12, first, it is determined whether or not the special variation counter is greater than “zero” (S550). Here, the “special variation counter” is a counter that counts a special variation period (execution period of the special variation mode) in which the high probability reduced variation pattern table B is set as a special symbol variation pattern table. At the end of the short-term game (2R probability variation big hit game, small hit game) started in the mode, it is set in the processing of S609i and S609n (see FIG. 14) described later.

  As a result of the determination processing in S550, if it is determined that the special variation counter is greater than “zero” (S550: YES), the current variation mode is “special variation mode”, and thus the high probability reduced variation pattern table B (See FIGS. 3 and 4) is set (S551).

  On the other hand, when it is determined that the special variation counter is not larger than “zero” (“zero”) (S550: NO), it is determined whether or not the probability variation flag is ON (S552). As a result, when it is determined that the probability variation flag is set to ON (S552: YES), it is further determined whether or not the variation shortening flag is set to ON (S553). As a result, when it is determined that the fluctuation shortening flag is set to ON (S553: YES), since the current fluctuation mode is the “high probability shortening fluctuation mode”, the probability fluctuation function and the fluctuation time reduction function The high probability shortening variation pattern table A (see FIG. 3 and FIG. 4) used during the operation is set (S554). On the other hand, if it is determined that the fluctuation shortening flag is not set to ON (S553: NO), since the current fluctuation mode is the “high probability normal fluctuation mode”, the probability fluctuation function is in operation. A high probability normal variation pattern table used when the variation time shortening function is not operated is set (S555).

  If it is determined in the process of S552 that the probability variation flag is not set to ON (S552: NO), it is determined whether or not the variation shortening flag is set to ON (S556). As a result, when it is determined that the fluctuation shortening flag is set to ON (S556: YES), since the current fluctuation mode is the “low probability shortening fluctuation mode”, the probability fluctuation function is not in operation. Then, a low probability shortening variation pattern table used when the variation time shortening function is activated is set (S557). On the other hand, if it is determined that the fluctuation shortening flag is not set to ON (S556: NO), since the current fluctuation mode is the “low probability normal fluctuation mode”, the probability fluctuation function and the fluctuation time reduction function are A low probability normal variation pattern table used at the time of non-operation is set (S558).

  When each variation pattern table distribution process (S508d, S508f, S508g) is completed as described above, the process proceeds to the process of S508h in FIG. 11 to acquire a variation pattern random number and a predetermined area in the RAM of the main control unit 200. Is read out (S508h). The symbol determination random number (special symbol determination random number acquired when the game ball enters the start port 28) is read.

  Next, a variation pattern and a stop symbol of the special symbol are determined (S508i). As the special symbol variation pattern, the variation pattern random number acquired in S508h is used to select a specific variation pattern from the variation pattern table set in the processing of S508d, S508f, and S508g. Note that each variation pattern table set in the processing of S508d, S508f, and S508g is associated with a variation pattern random value and a variation pattern, and a variation pattern corresponding to the variation pattern random value acquired in S508h. The variation pattern to be used this time is determined. The special symbol stop symbol is a symbol determination table stored in a predetermined area of the main control unit 200 using the special symbol determination random number read in S508h when the result of the special symbol success / failure determination is a big hit. If the result of the special symbol success / failure judgment is a small hit, it will be determined as a small hit symbol. If the result of the determination is not good, it is determined as a missed symbol. Similarly to the variation pattern table, the symbol determination table also associates the special symbol determination random number value with each jackpot symbol, and the jackpot symbol corresponding to the special symbol determination random number value read in S508h is It is determined as a jackpot symbol to be stopped and displayed.

  Next, according to the stop symbol and the variation pattern determined in the process of S508i, the first special symbol display unit 61 or the second special symbol display unit 62 starts the variation display of the special symbol (S508j), 1 is subtracted (S508k), and a symbol change start command is transmitted to the sub-control unit 260 (S508l). The “design variation start command” includes a variation pattern designation command, a stop information designation command, and a hold count designation command. The variation pattern designation command is a command for designating the variation pattern of the special symbol determined in the processing of S508i, and the special symbol information designation command is a command for designating the stop symbol of the special symbol similarly determined in the processing of S508i. is there. The number-of-holds designation command is a command for designating the number of special symbols held after the start of variable symbol display. When this symbol variation start command is transmitted to the sub-control unit 260, the symbol variation effect (effect symbol variation display) is started under the control of the sub-control unit 260 and the effect display control unit 280 that have received these commands. The processing up to this point is when the special symbol variation display is started.

  Next, returning to FIG. 9A, 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 this case (S510: YES), the special symbol variation display is stopped (S511), and a special symbol designating command indicating that the special symbol variation display is stopped is transmitted to the sub-control unit 260 (S512). A stop display time is set (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: NO), the special symbol game processing is terminated and it is determined that the special symbol stop symbol display time has elapsed. If it is (S514: YES), the stop symbol of the special symbol stopped and displayed on the first special symbol display unit 61 or the second special symbol display unit 62 is a winning symbol (big hit symbol or small hit symbol) Is determined (S515 in FIG. 9B). As a result, when it is determined that the stop symbol of the special symbol is a winning symbol (S515: YES), the type of the current hit in the predetermined area of the RAM of the main control unit 200, the current value of the special fluctuation counter, The state of the current game state flag (probability change flag, change shortening flag, release extension flag) and the like are stored (S516). Then, the special variation counter is initialized (set to zero) (S517).

  Next, it is determined whether or not the winning symbol stopped and displayed on the first special symbol display unit 61 or the second special symbol display unit 62 is a small hit symbol (S518). As a result, if it is determined that the winning symbol that has been stopped is not a small symbol (S518: NO), is the winning symbol that has been stopped displayed also a 2R probability variable big symbol (second probability variable big symbol)? It is determined whether or not (S519). As a result, when it is determined that the winning symbol that has been stopped is a 2R probability variation big winning symbol (S519: YES), the 2R big winning hole opening that is the opening pattern of the second big winning game big winning hole 33a is opened. When a pattern is set (S520) and it is determined that the hit symbol that is stopped and displayed is not a 2R probability variation big hit symbol (when it is a 15R probability variation big hit symbol or a 15R normal big hit symbol) (S519: NO), the first big hit The 15R special winning opening opening pattern, which is the opening pattern of the gaming special winning opening 33a, is set (S521). Then, the big hit game flag is set to ON (S522). As a result, the big hit game is started according to the big winning opening opening pattern set in the process of S520 or S521.

  Next, it is determined whether or not the probability variation flag is ON (S523). If it is determined that the probability variation flag is ON (S523: YES), the probability variation flag is set to OFF (S524) and the variation is shortened. The flag is set to OFF (S525), and the open extension flag is set to OFF (S526). Thereby, with the start of the big hit game, the probability variation function, the variation time shortening function, and the open time extension function stop operating.

  On the other hand, when it is determined that the probability variation flag is not ON (S523: NO), it is determined whether or not the fluctuation shortening flag is ON (S527), and when it is determined that the fluctuation shortening flag is not ON. (S527: NO), the special symbol game process is terminated. On the other hand, when it is determined that the fluctuation shortening flag is ON (S527: YES), the fluctuation shortening flag is set to OFF (S525), and the release extension flag is set to OFF (S526). Thereby, with the start of the big hit game, the fluctuation time shortening function and the open time extending function stop operating.

  On the other hand, when it is determined in the determination process of S518 that the winning symbol stopped on the first special symbol display unit 61 or the second special symbol display unit 62 is a small symbol (S518: YES), A big winning opening opening pattern for small hits is set (S528). The small winning big winning opening opening pattern is an opening pattern of the small winning game big winning opening 33a, and is the same as the 2R big winning opening opening pattern set in the process of S520. Accordingly, when a game per short period (2R probability variation big hit game, small hit game) occurs, the opening / closing operation of the big prize opening 33a is performed in a common (identical) manner. It becomes difficult to identify (understand) whether “2R probability variation big hit” or “small hit” has occurred.

  Then, the small hit game flag is set to ON (S529). As a result, the small hit game is started according to the small winning big opening opening pattern set in the process of S528.

  Next, it is determined whether or not the fluctuation shortening flag is ON (S530). As a result, when it is determined that the variation shortening flag is not ON (S530: NO), the special symbol game process is terminated, and when it is determined that the variation shortening flag is ON (S530: NO), the variation shortening is performed. The counter is decremented by “1” (S531), and it is determined whether or not the fluctuation shortening counter has become “zero” (S532). When it is determined that the fluctuation shortening counter is not “zero” (S532: NO), the special symbol game process is terminated, and when it is determined that the fluctuation shortening counter is “zero” (S532: YES). ), The fluctuation shortening flag is set to OFF (S525), and the open extension flag is set to OFF (S526). As a result, the fluctuation time shortening function and the open time extending function stop operating.

  Next, in the determination process of S515, it is determined that the stop symbol of the special symbol stopped and displayed on the first special symbol display unit 61 or the second special symbol display unit 62 is not a winning symbol (big hit symbol or small hit symbol). If it is detected (in the case of a missing symbol) (S515: NO), it is determined whether or not the special variation counter exceeds “zero” (S533). As a result, when it is determined that the special variation counter does not exceed “zero” (S533: NO), the process proceeds to S537. On the other hand, when it is determined that the special fluctuation counter exceeds “zero” (S533: YES), the special fluctuation counter is decremented by 1 (S534).

  Next, it is determined whether or not the special variation counter is “zero” (S535). As a result, when it is determined that the special variation counter is not “zero” (S535: NO), the process proceeds to S537. On the other hand, when it is determined that the special variation counter is “zero” (S535: YES), a mode designation command is transmitted to the sub-control unit 260 (S536). The “mode designation command” is based on the state of the game state flag (probability variation flag, release extension flag) and special variation counter, “low probability normal variation mode”, “high probability normal variation mode”, “low probability shortened variation mode” ”,“ High probability shortening variation mode ”, or“ Special variation mode ”. Here, since the special variation mode is completed and the game mode is shifted to the “high probability shortened variation mode” which is the game mode before the transition to the special variation mode, a command for designating the “high probability shortened variation mode” is transmitted.

  Next, it is determined whether or not the fluctuation shortening flag is ON (S537). As a result, if it is determined that the fluctuation shortening flag is not ON (S537: NO), the special symbol game process is terminated. On the other hand, when it is determined that the fluctuation shortening flag is ON (S537: YES), “1” is subtracted from the fluctuation shortening counter (S538). The fluctuation shortening counter is for monitoring the operating period of the fluctuation time shortening function and the opening time extension function. At the end of the winning game, the type of the big hit symbol that triggered the winning game (the winning game) The predetermined set value is set in the processing of S609f and S609j described later (see FIG. 14) in accordance with the gaming state at the time of occurrence of the game.

  Then, it is determined whether or not the fluctuation shortening counter obtained by subtracting “1” in S538 is “zero” (S539). As a result, when it is determined that the fluctuation shortening counter is not “zero” (S539: NO), the special symbol game process is terminated, and when it is determined that the fluctuation shortening counter is “zero” (S539). : YES), the fluctuation shortening flag is set to OFF (S540), and the release extension flag is set to OFF (S541).

  As a result, the fluctuation time shortening function and the open time extending function stop operating. Then, a mode designation command indicating a fluctuation mode (high probability normal fluctuation mode or low probability normal fluctuation mode) in which the fluctuation time shortening function and the open time extension function do not operate is transmitted to the sub-control unit 260 (S542). Upon receiving this mode designation command, the sub-control unit 260 displays characters, characters, backgrounds, and the like indicating that the variable time shortening function and the open time extending function are inactive (normal state). Process to be displayed.

  Next, the winning game process (S600) will be described based on the flowchart of FIG. First, it is determined whether or not a winning game is in progress (whether the big hit game flag or the small hit game flag is ON) (S601). As a result, if it is determined that the winning game is not being played (the big hit game flag and the small hit game flag are OFF) (S601: NO), the winning game process is ended and the winning game is being executed (the big hit game flag) If it is determined that the small winning game flag is ON) (S601: YES), it is determined whether or not the special winning opening 33a is open (S602). As a result, when it is determined that the special winning opening 33a is being opened (S602: YES), it is determined whether or not the opening time of the special winning opening 33a has elapsed (S603), and the special winning opening 33a is determined. 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 (S604: NO), the winning game process is terminated and the prescribed winning number has been won in the big winning opening 33a. When it is determined (S604: YES) or when it is determined that the opening time of the special winning opening 33a has elapsed (S603: YES), the special winning opening 33a is closed (S605).

  If it is determined in the determination process of S602 that the special winning opening 33a is not open (S602: NO), it is determined whether or not a winning game end condition is satisfied (S606). In the determination process of S606, if the first big hit game, the number of rounds of the big hit game has reached the maximum continuous round number of 15 rounds, if the second big hit game, the round number of the big hit game is the maximum continuous round It is determined whether or not the number of rounds 2 has been reached, and whether or not the number of times of opening and closing of the big prize opening 33a has reached 2 in the case of a small hit game.

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

  If it is determined in the determination process of S606 that the winning game end condition is satisfied (S606: YES), a winning game end process is performed (S609). Here, the winning game end process (S609) will be described based on the flowchart of FIG.

  In the winning game end process, first, the winning game flag (big hit game flag or small hit game flag) is set to OFF (S609a). Next, it is determined whether or not the stop symbol of the special symbol that triggered the start of the current hit game is a big hit symbol (S609b). As a result, when it is determined that the stop symbol of the special symbol is a big hit symbol (S609b: YES), whether or not the big hit symbol is a probability variable big hit symbol (first probability variable big hit symbol or second probability variable big hit symbol). Is determined (S609c).

  As a result, if it is determined that the jackpot symbol that triggered the start of the current winning game is a probability variation jackpot symbol (S609c: YES), the probability variation flag is set to ON (S609d). Thereby, the operation of the probability variation function starts (becomes a high probability state).

  Next, it is determined whether or not the probability variation jackpot symbol is a 15R probability variation jackpot symbol (first probability variation jackpot symbol), that is, whether or not the winning game to be finished this time is the first probability variation jackpot game (S609e). As a result, when it is determined that the symbol is a 15R probability variation big hit symbol (S609e: YES), the variation shortening counter is set to “10,000” (S609f), the variation shortening flag is set to ON (S609k), The release extension flag is set to ON (S609l). As a result, the operation of the variable time shortening function and the open time extending function starts. In this case, the fluctuation time shortening function and the opening time extension function are continuously operated until the number of executions of the special symbol fluctuation display after the end of the hit game reaches “10,000 times”. Specifically, the fluctuating time shortening function and the opening time extending function are operated until the next big hit game is started.

  If it is determined in the determination process of S609e that the probability variation big winning symbol that is the start trigger of the current hit game is not the first probability variable big winning symbol (second probability varying big winning symbol) (S609e: NO), Whether the game mode (game state) in the main control unit 200 when the 2R probability variable big hit occurs is the low probability normal variation mode in which any of the probability variation function, the variation time shortening function, and the open time extension function is not activated It is determined whether or not (S609g).

  As a result, when it is determined that the game mode at the time of occurrence of the 2R probability variation big hit is the low probability normal variation mode (S609g: YES), the process proceeds to S609o. As a result, only the probability variation function is activated, and the “latency probability variation state” is entered in which the variation time shortening function and the open time extension function are not activated. On the other hand, when it is determined that the game mode when the 2R probability variable big hit occurs is not the low probability normal variation mode (S609g: NO), the game mode when the 2R probability variable big hit occurs is the probability variation function, the variation time shortening function, and the release. It is determined whether or not it is a high probability reduction variation mode in which the time extension function is activated (S609h).

  As a result, when it is determined that the game mode at the time of occurrence of the 2R probability variable big hit is the high probability shortening variation mode (S609h: YES), “50” is set to the special variation counter (S609i), and the processing of S609f is performed. Transition. As a result, the execution period of the special variation mode is set until the number of variations of the special symbol reaches 50, and the game mode shifts from the high probability reduced variation mode to the special variation mode. On the other hand, when it is determined that the game mode at the time of occurrence of the 2R probability variable big hit is not the high probability shortening variation mode (the low probability shortening variation mode) (S609h: NO), the special variation counter is not set, and the processing of S609f Transition to processing. Then, the fluctuation shortening counter is set to “10,000” (S609f), the fluctuation shortening flag is set to ON (S609k), and the release extension flag is set to ON (S609l). Thereby, in addition to the operation of the probability variation function, the operation of the variation time shortening function and the open time extension function are started. In this case, the fluctuation time shortening function and the opening time extension function are continuously operated until the number of executions of the special symbol fluctuation display after the end of the hit game reaches “10,000 times”. Specifically, the fluctuating time shortening function and the opening time extending function are operated until the next big hit game is started.

  Further, when it is determined in the determination process of S609c that the big hit symbol that triggered the start of the current hit game is not a probable big hit symbol (usually a big hit symbol) (S609c: NO), the fluctuation reduction counter is set. It is set to “100” (S609j), the fluctuation shortening flag is set to ON (S609k), and the release extension flag is set to ON (S609l). Thereby, the operation of the variable time shortening function and the open time extending function starts (start of the short time game). In this case, the operation of the variation time shortening function and the release time extension function is continuously performed until the number of executions of the variation display of the special symbol after the end of the hit game reaches “100 times”.

  Further, when it is determined in the determination process of S609b that the stop symbol of the special symbol is not a big hit symbol (a small hit symbol) (S609b: NO), the game mode at the time of occurrence of the small hit is a high probability reduction variation It is determined whether or not the mode is selected (S609m). As a result, when it is determined that the gaming mode at the time of occurrence of the small hit is the high probability shortening variation mode (S609m: YES), “50” is set in the special variation counter, and the process proceeds to S609o. As a result, the execution period of the special variation mode is set until the number of variations of the special symbol reaches 50, and the game mode shifts from the high probability reduced variation mode to the special variation mode. On the other hand, if it is determined that the game mode at the time of occurrence of the small hit is not the high probability shortening variation mode (S609m: NO), the process proceeds to S609o without setting the special variation counter.

  Then, a mode designation command indicating the current game mode in the main control unit 200 (the presence / absence of each operation of the probability variation function, the variation time shortening function, and the open time extension function) is transmitted to the sub-control unit 260 (S609o).

  Here, the correspondence between the processing shown in the flowcharts of FIGS. 7 to 14 and the respective means of the present invention will be described. The processing of S401 to S409 (FIGS. 7 and 8) is the normal symbol of the present invention. Corresponding to the game execution means, “S501 to S511 processing (FIGS. 9A, 10 and 11)” corresponds to the special symbol game execution means of the present invention, and “S522, S529, S601 to S608 processing”. (FIG. 9B, FIG. 13) corresponds to the winning game execution means, “S609d processing (FIG. 14)” corresponds to the probability variation means, and “S554, S609k processing (FIGS. 12, 14). "Corresponds to the variation time shortening means," S413 and S609l processes (FIGS. 7 and 14) "corresponds to the open time extension means, and" S551, S609i and S609n processes (FIGS. 12 and 14) " Corresponding to special variable means, "S 08d, S509d, S508f, S509f, S508g, S509g, the process of S550～S558 (11, 12) "corresponds to the change pattern determining means.

  According to the present embodiment described above, the use of the high probability shortening variation pattern table A as the variation pattern table for the special symbol is started in accordance with the shift to the high probability shortening variation mode after the probability variation big hit game is over. Then, during the probability variation game (in the high probability shortening variation mode), it is assumed that the operation of the probability variation function, the variation time shortening function and the open time extension function is continued “per short period (2R probability variation large hit, small hit ) ”Occurs, the high probability shortened variation pattern table B (see FIG. 4B) has a high selection ratio of the short-term variation pattern as the special symbol variation pattern table after the end of the game per short period. Use begins. Thereby, the variation frequency of the special symbol is improved from before the occurrence for a short period, and the next hit can be generated earlier. As a result, it is possible to give a new game value that the game can be smoothly advanced from before the occurrence per short period by the occurrence of “per short period (2R probability variation big hit, small hit)” in the high probability shortening variation mode. Can do.

  In addition, the high probability shortening variation pattern table B of the present embodiment does not include a reach variation deviation pattern (long-term variation pattern) (see FIG. 4B). For this reason, if a reach fluctuation occurs after the occurrence of “per short period (2R probability variable big hit, small hit)” in the high probability shortening fluctuation mode (during probability variation game), it is predicted that the hit will occur due to the reach fluctuation. It is possible to provide a playability that can be performed.

  In this embodiment, the special variation counter is set to “50” at the end of the game per short period in the high probability shortening variation mode. For this reason, the “special variation period (special variation mode)” in which the variation pattern of the special symbol is determined using the high-probability shortened variation pattern table B is a fixed period (the variation of the special symbol) after the game ends per short period. It ends in 50 times). Thereby, the special variation mode is performed only for a certain period after the game ends per short period, and it is possible to impress the player that it is a special game mode.

  Further, in this embodiment, there is a priority variation function that preferentially varies and displays the second special symbol with respect to the first special symbol. In such a configuration having the priority variation function, when all of the second special symbol hold is exhausted, a first special symbol success / failure determination with a high winning probability of “per short period (2R probability variation big hit, small hit)” is performed. . For this reason, when all of the second special symbol hold is digested during the probability variation game and the first special symbol determination is made, “per short period (2R probability variation big hit, small hit)” occurs, and the gaming interest is reduced. Probability is high. On the other hand, in this embodiment, when “per short period” occurs during probability variation game (high probability shortening variation mode), the variation frequency of the special symbol is improved compared to before the occurrence per short period. Since the game can proceed smoothly from before the occurrence, it is possible to suppress a decrease in the game interest due to the occurrence of “per short period”.

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

  FIG. 15 is a flowchart showing the process at the end of the hit game in the second embodiment, and corresponds to FIG. 14 in the first embodiment.

  As shown in FIG. 15, in the second embodiment, when it is determined that the game mode when the 2R probability variable big hit occurs is the high probability shortening variation mode (S609h: YES), after the probability variable big hit game ends (high It is determined whether or not the number of fluctuations of the special symbol after the transition to the probability shortening fluctuation mode has reached a predetermined number (S609p). The “predetermined number of times” is a value that is set to define the start time when the special variation counter can be set after the probability variation big hit game is over (after the transition to the high probability shortening variation mode), and is set to “50” in this embodiment. ing.

  As a result, if it is determined that the number of changes in the special symbol in the high probability shortening variation mode after the probability variation big hit game is over (S609p: YES), the special variation counter is set to “50”. Set (S609i), the process proceeds to S609f. On the other hand, when it is determined that the number of times of variation of the special symbol in the high probability shortening variation mode has not reached the predetermined number (S609p: NO), the processing proceeds to S609f without setting the special variation counter. .

  In the second embodiment, when it is determined that the game mode at the time of occurrence of the small hit is the high probability shortening variation mode (S609m: YES), after the probability variation big hit game ends (after the transition to the high probability shortening variation mode) ) Is determined whether or not the number of fluctuations of the special symbol has reached a predetermined number (here, “50 times”) (S609q). As a result, if it is determined that the number of changes in the special symbol after the probability variation big hit game ends (after the transition to the high probability shortening variation mode) has reached the predetermined number (S609q: YES), the special variation counter is set to “50”. ”Is set (S609n), and the process proceeds to S609o. On the other hand, if it is determined that the number of changes in the special symbol after the end of the probable big hit game (after transition to the high probability shortening variation mode) has not reached the predetermined number (S609q: NO), the special variation counter is set. Instead, the process proceeds to S609o.

  According to the configuration of the second embodiment described above, until the number of changes of the special symbol in the high probability reduction variation mode after the probability variation big hit game ends reaches a predetermined number of times (in this embodiment, “50 times”), the high Special fluctuation mode in which the special fluctuation counter is not set and the high probability reduction fluctuation pattern table B is used even if “game per short period (2R probability variation big hit game, small hit game)” is executed during the probability reduction fluctuation mode Do not move to.

  If “per short period (2R probability variation big hit, small hit)” occurs after the game has progressed to some extent after the probability variation big hit game ends (after transition to the high probability shortening variation mode), immediately after the probability variation big hit game ends, Compared with the case where “per short period” occurs, the period of “redo” for the occurrence of another hit is felt longer, which causes a significant decrease in the entertainment interest of the game. On the other hand, in the configuration of the second embodiment, it is possible to shift to the special variation mode when the number of variations of the special symbol exceeds a predetermined number after the probability variation big hit game ends. As a result, when “per short period” occurs after the game has progressed to some extent from the end of the probable big hit game, the frequency of fluctuation of the special symbol will improve, and the game will proceed more smoothly than before the occurrence per short period. Since the profit of being able to perform is obtained, it is possible to suppress a decrease in the entertainment interest due to the occurrence per short period.

(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to FIG. Only the parts different from the above embodiments will be described below.

  In the third embodiment, as a normal symbol fluctuation display time, in addition to the normal fluctuation fluctuation time (30 seconds) and the shortened fluctuation fluctuation time (2 seconds), the special symbol shorter than the shortened fluctuation fluctuation time (2 seconds). A fluctuation time for fluctuation (0.5 seconds) is provided.

  FIG. 16 is a flowchart showing the normal symbol variation display process of the third embodiment, and corresponds to FIG. 8 of the first embodiment. The main control unit 200 that executes the normal symbol variation display process shown in FIG. 16 corresponds to the normal symbol game execution means, variation time shortening means, and special variation means of the present invention.

  As shown in FIG. 16, in the third embodiment, whether or not the special variation counter has exceeded zero after setting the normal symbol hit symbol or the off symbol in the processing of S407d and S407e (the special variation period is It is determined whether it is set (S407j). As a result, when it is determined that the special variation counter is greater than zero (the special variation period is set) (S407j: YES), the variation time for special variation (0.5) is used as the variation time of the normal symbol. Second) is set (S407k). On the other hand, when it is determined that the special variation counter does not exceed zero (the special variation period is not set) (S407j: NO), the normal symbol variation time is normally set based on the state of the variation shortening flag. The variation time for variation (30 seconds) or the variation time for shortening variation (2 seconds) is set. In the third embodiment, “S407j: YES → S407k processing (FIG. 16)” in addition to the above-mentioned “S609i and S609n processing (FIGS. 14 and 15)” corresponds to the special variation means of the present invention. is doing.

  According to the third embodiment described above, in the high probability shortening variation mode after the probability variation big hit game is over, the variation time for shortening variation (2) which is shorter than the variation time for normal variation (30 seconds) as the variation time of the normal symbol. Second) is set. And if “per short period (2R probability variation big hit, small hit)” occurs in the high probability shortened variation mode (during probability variation game), the hit per “short period (2R probability variation big hit, small hit)” After the game is over, the normal symbol special fluctuation period (normal symbol special), which is set as the special symbol fluctuation time (0.5 seconds), which is shorter than the short fluctuation time (2 seconds), is set as the normal symbol fluctuation time. Move to the fluctuation mode. Thereby, after the game per short period ends, the variation frequency of the normal symbol is improved from before the game starts per short period, and the opening frequency of the second start port 28b is improved. As a result, the frequency of entering the game ball into the second starting port 28b is improved, so that the frequency of fluctuation of the special symbol is improved and the next hit can be generated earlier. In this way, with the occurrence of “per short period (2R probability variable big hit, small hit)” in the high probability shortening fluctuation mode (probability variation game), it is generated per short period by further shortening the fluctuation time of normal symbols It is possible to give a new game value that the game can be smoothly advanced from before. In particular, by generating the special symbol special variation mode in the first and second embodiments and the normal symbol special variation mode in the third embodiment at the same time, the variation frequency of the special symbol can be improved more effectively. Can be realized.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described with reference to FIG. Only the parts different from the above embodiments will be described below.

  In the fourth embodiment, the opening pattern of the second start port 28b is opened from the second opening pattern (4 seconds) in addition to the first opening pattern (0.5 seconds) and the second opening pattern (4 seconds). A long third open pattern (6 seconds) is provided.

  FIG. 17 is a flowchart showing the normal symbol game process of the fourth embodiment, and corresponds to FIG. 7 of the first embodiment. As shown in FIG. 17, in the fourth embodiment, when it is determined in the determination processing in S411 when the normal symbol hit symbol is stopped and displayed, the release extension flag is not set to ON ( (S411: NO), the first opening pattern (0.5 seconds in this embodiment) is set as the opening pattern of the second start port 28b (S412), and it is determined that the opening extension flag is set to ON (S411: YES), it is determined whether or not the special fluctuation counter exceeds zero (whether or not the special fluctuation period is set) (S417).

  As a result, when it is determined that the special fluctuation counter exceeds zero (the special fluctuation period is set) (S417: YES), the third opening pattern (main book) is used as the opening pattern of the second start port 28b. In the embodiment, 6 seconds) is set (S418). On the other hand, when it is determined that the special fluctuation counter does not exceed zero (the special fluctuation period is not set) (S417: NO), the second opening pattern (this embodiment) is used as the opening pattern of the second start port 28b. In the example, 4 seconds) is set (S418).

  According to the fourth embodiment described above, during the high probability shortening variation mode after the probability variation big hit game is over, the opening time of the second start port 28b is longer than the first opening pattern (0.5 seconds). A long second opening pattern (4 seconds) is set. And if “per short period (2R probability variation big hit, small hit)” occurs in the high probability shortened variation mode (during probability variation game), the hit per “short period (2R probability variation big hit, small hit)” After the game is over, a special opening period (special opening mode) in which a third opening pattern (6 seconds) having a longer opening time than the second opening pattern (4 seconds) is set as the opening pattern of the second start port 28b. Migrate to As a result, the frequency of opening the second start opening 28b is improved after the game per short period due to the short period ends, and the frequency of entering the game ball into the second start opening 28b is improved. As a result, the variation frequency of the special symbol is improved, so that the next hit can be generated earlier. As described above, the occurrence of “per short period (2R probability variation big hit, small hit)” in the high probability shortening variation mode (probability variation game) is triggered, and the opening time of the second start port 28b is further extended. It is possible to give a new game value that the game can be smoothly advanced from before the occurrence. In particular, by executing the special opening mode of the second start port 28b together with the special symbol special variation mode in the first and second embodiments and the normal symbol special variation mode in the third embodiment, The fluctuation frequency can be improved more effectively.
