Abstract

PROBLEM TO BE SOLVED: To improve the interest of a game in a game machine for performing the preferential variation of a second special symbol.SOLUTION: The game machine is set so as to perform the variable displaying of a second symbol in priority to the variable displaying of a first symbol and to allow gain, to be obtained by a player, to be larger in a jackpot game to be performed, with the stop displaying of the second symbol as an opportunity, than a jackpot game to be performed with the stop displaying of the first symbol as an opportunity. At least one of the variable times of the first symbol and the second symbol is set to be a first variable time till the number of times of variations of the first symbol and the second symbol reach a prescribed number of times from the occurrence of an open frequency improvement state. After the number of times of variations of the first symbol and the second symbol reach the prescribed number of times after the occurrence of the open frequency improvement state, the variable time of the symbol with the setting of the first variable time between the first and second symbols is set to be a second variable time longer than the first variable time. Thus, the start of the variable displaying of the first symbol is suppressed compared with a case before the number of times of variations of the first symbol and the second symbol reach the prescribed number of times.

Description

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

  In the pachinko machine, the winning / failing judgment is made by entering the game ball at the starting port and the special symbol is started to be displayed in a variable manner. When the judgment result is a big hit, the special symbol is stopped and displayed with the big hit symbol and the big hit game is started. To do. In such a pachinko gaming machine, a first special symbol that starts to change by entering a game ball into a fixed start opening with a fixed probability of entry, and a game ball entry into an open / close starter that changes the entry probability There has been proposed a gaming machine provided with a priority variation function that provides a second special symbol that starts to fluctuate and displays the second special symbol in a preferential manner over the first special symbol (see Patent Document 1). In gaming machines adopting such priority fluctuations, the type of jackpot game that occurs in each special symbol (for example, the profit that the player can obtain) is made different so that a specific time like when the open time extension function is activated. It is possible to realize special game characteristics such as making it easy to generate a big hit advantageous to the player in the gaming state.

JP 2007-268126 A

  However, in the above-described gaming machine, in order to surely realize the priority change of the second special symbol, the control for making the first special symbol difficult to change when the open time extension function is activated (for example, the change time of the first special symbol is reduced). In some cases, the second special symbol is held longer or the second special symbol is suspended as the number of the second special symbol is reduced. In such a case, only the second special symbol is variably displayed consistently during the opening time extension function operation, and there is a problem that the game becomes monotonous and the gaming interest is lowered.

  Therefore, in view of the above points, the present invention has an object to improve the gaming interest in a gaming machine that performs priority change of the second special symbol.

In order to achieve the above object, the gaming machine of the present invention provides:
A first per-lottery random number storage means for acquiring and storing a first per-lottery random number when a game ball enters the fixed first start opening where a game ball can always enter;
When a game ball enters the variable second starting port that changes between a closed state where it is difficult to enter a game ball and an open state where it is easy to enter a game ball, a lottery random number per second is acquired. Second lottery random number storage means for storing
When the first per lottery random number is stored, the first per lottery is executed using the first per lottery random number, and the first symbol display unit displays the first symbol according to the result of the first per lottery. The first symbol game execution means for displaying the change over the predetermined change time and then stopping the display.
When the second lottery random number is stored, the second lottery is executed using the second lottery random number, and the second symbol display unit displays the second symbol according to the second lottery result. The second graphic game execution means for displaying the change after the change display for a predetermined change time,
When the first lottery random number is stored and the second lottery random number is stored, the second symbol variation display is performed in preference to the first symbol variation display. 2 design priority change means,
A privilege granting means for granting a predetermined privilege when the first symbol or the second symbol is stopped and displayed with a predetermined hit symbol;
Opening that generates an open frequency improving state that improves the frequency at which the second start port is in the open state until the total number of fluctuations of the first symbol and the second symbol after giving the privilege reaches a predetermined limit number of times. Frequency improvement means,
Fluctuation time setting means for setting the fluctuation time of the first symbol and the second symbol in the release frequency improvement state,
The privilege giving means gives a privilege that the second symbol is stopped and displayed with the winning symbol rather than the first symbol is stopped and displayed with the winning symbol,
The variation time setting means includes:
In the release frequency improving state, after the total number of changes reaches a predetermined number of change designations less than the limit number, the change display frequency of the first symbol is lower than before the change designation number is reached. In addition, the variation time of at least one of the first symbol and the second symbol is set to a longer time than before reaching the specified number of changes.

  According to the present invention, in the release frequency improvement state in which the priority variation function of the second symbol effectively acts, the total number of variations (total number of variations) of each symbol is the limit number of times of release frequency improvement (for example, 100 times). After reaching a predetermined number of change designations (for example, 50 times), the fluctuation time of at least one of the first and second symbols is longer than before reaching the number of change designations, and before reaching the number of change designations. The variation display frequency of the first symbol is lowered. That is, it becomes difficult for the first symbol to be variably displayed from the middle of the open frequency improvement state, and the variability display frequency of the first symbol to which a privilege with a small profit can be given decreases. As a result, it is possible to realize a new game progress mode in which the variation display frequency of the first symbol is changed according to the progress of the game in the state of increasing the release frequency in which the priority variation function of the second symbol effectively operates, and the release frequency is improved. It is possible to give new fun to the game in the state.

  Note that “the privilege granting unit gives a privilege that the second symbol is stopped and displayed at the winning symbol rather than the first symbol is stopped and displayed at the winning symbol” It is only necessary that the benefit related to the second pattern is more profitable than the privilege related to. “Bonus” means, for example, “execution of a hit game (high profit game that opens a closed big prize opening) when triggered by a stop display of a winning symbol” or “advantage state after a win game” (Probability of occurrence etc.) ”corresponds. In addition, “the size of the privilege” means, for example, “the amount of the total amount of winning balls obtained per game”, “the length of the opening time of the big winning opening during the winning game”, “the big winning opening during the winning game” “Some of the number of times of opening”, “Possibility of occurrence of advantageous state (probability change state, etc.) after winning game”, “Long or short period of occurrence of advantageous state (probability change state, etc.) after winning game”, etc.

  In addition, “after the total number of fluctuations reaches a predetermined number of change designations less than the limit number of times, the first symbol fluctuation display frequency is lower than before the change designation number of times is reached. “Set the variation time of at least one of the first symbol and the second symbol to a longer time than before reaching the number of designated changes” means “suppression of variation display of the first symbol after reaching the designated number of changes” ”For the purpose of setting the variation time of the first symbol and the second symbol so that the first symbol variation display frequency is lower than before the total variation number reaches the designated change number. Set the change time of the first symbol after reaching the specified number of changes to a longer time than before reaching the specified number of changes ”or“ Change time of the second symbol after reaching the specified number of changes ” Is longer than before the specified number of changes is reached “Set the time”, “Set the first symbol variation time and the second symbol variation time after reaching the specified change count to a longer time than before reaching the specified change count”, etc. Is mentioned.

In addition, the gaming machine of the present invention,
The variation time setting means includes:
In the release frequency improving state, after the total number of changes reaches the first change designation number as the number of change designations, the variation display frequency of the first symbol is higher than before the first change designation number is reached. The fluctuation time of at least one of the first symbol and the second symbol is set to be longer than before reaching the first change designated number so as to be lowered,
After the total change count reaches the second change specification count that is larger than the first change specification count as the change specification count, the variation of the first symbol than before the second change specification count is reached. In order to reduce the display frequency, the variation time of at least one of the first symbol and the second symbol is set to a longer time than before reaching the second designated number of changes.

  As a result, in the open frequency improvement state in which the priority variation function of the second symbol works effectively, the variation display frequency of the first symbol is changed to the progression of the game (when the first change designation number is reached, the second change designation number is reached). It is possible to realize a new game progress mode in which the game is gradually reduced according to the time), and it is possible to give a new interest to the game in the open frequency improved state.

In addition, the gaming machine of the present invention,
The variation time setting means includes:
In the release frequency improving state, after the total number of changes reaches the first change designation number, one of the first symbol and the second symbol is changed to the first change designation number. Set a longer time than before
After the total fluctuation count reaches the second change designation count, the other fluctuation time of the first symbol and the second symbol is set to a longer time than before reaching the first change designation count. It is characterized by setting.

  As a result, in the release frequency improvement state in which the priority variation function of the second symbol works effectively, according to the progress of the game (when the first change specified number of times and the second change specified number of times are reached), The variation display mode of the first symbol and the second symbol changes so as to reduce the variation display frequency, and a new game progress mode in which the variation display frequency of the first symbol is gradually decreased as the game progresses can be realized. It is possible to give the game a new interest in the game in the state where the opening frequency is improved.

In addition, the gaming machine of the present invention,
The variation time setting means includes:
In the release frequency improving state, after the total number of changes reaches the first change designation number as the number of change designations, the variation display frequency of the first symbol is higher than before the first change designation number is reached. The fluctuation time of at least one of the first symbol and the second symbol is set to be longer than before reaching the first change designated number so as to be lowered,
After the total change count reaches the second change specification count that is larger than the first change specification count as the change specification count, the variation display frequency of the first symbol reaches the first change specification count. In order to be the same as before, the variation time of the first symbol and the second symbol is set to the same time as before reaching the first designated number of changes.

  As a result, in the open frequency improvement state in which the priority variation function of the second symbol acts effectively, the variation display frequency of the first symbol is set to a certain period (the second change designation number of times after reaching the first change designation number of times. The game progress mode can be realized by changing only the game period until the game is reached, and the game in the open frequency improvement state can be given new interest.

  According to the configuration of the present invention described above, the gaming interest can be improved in the gaming machine that performs the priority change of the second special symbol.

In the present embodiment, a large liquid crystal display device is used as the effect display device 25, and various effect displays are performed in the display area of the effect display device 25.

  The big winning device 33 is arranged below the central device 24 in the game area 21. The first decoration device 50 is arranged on the left side of the big prize device 33 in the game area 21, the second decoration device 60 is arranged on the right side of the big prize device 33 in the game area 21, and the decoration devices 50, 60 are so-called side. Make up decorations. Further, the first winning device 34 is integrated with the left winning holes 34 and 35, and the second winning device 60 is integrated with the right winning ports 36 and 37.

  The normal symbol operating gate 27 is provided on the left side of the central device 24. Inside the normal symbol operation gate 27, a normal symbol operation gate detection switch 27s (see FIG. 4) for detecting the passage of a game ball flowing down on the game board is provided. When the game ball passes through the normal symbol operating gate 27, the normal symbol starts to fluctuate.

  The start port 28 is provided below the central position of the central device 24. The start port 28 is a first start port provided on the upper side, in which two entrance ports formed with a game ball receiving port for receiving a game ball flowing down on the surface of the game board 20 are arranged side by side in the vertical direction. 28a and a second start port 28b provided on the lower side.

  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. 4) for detecting a game ball entering the first start port 28a, and a game ball entering the second start port 28b. A start opening ball detection switch 28t (see FIG. 4) for detection and a start opening solenoid 28c (see FIG. 4) 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). 4), and an incoming ball detection switch 33s (see FIG. 4) for detecting an incoming game ball.

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

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

  The normal symbol display part 51 is comprised from one LED, and a normal symbol is displayed by this LED. In the normal symbol display unit 51, the normal symbol variation display and stop display are performed. In the normal symbol display unit 51, the normal symbol starts to change when the game ball passes through the normal symbol operating gate 27, and after a predetermined time has passed, the normal symbol hits and stops display in the normal symbol display mode or the dismissed normal symbol display mode. Is done. When the normal symbol is stopped and displayed in the preset normal symbol display mode, the second start port 28b is opened according to a predetermined opening pattern. A plurality of opening patterns of the second start port 28b are set. When the opening time extension function for extending the opening time of the second start port 28b is not in operation (normal time), a short opening pattern in which a first opening time (for example, 1 to 2 seconds) is set is set and opened. When the time extension function is activated, a long-time opening pattern in which a second opening time (for example, 4 to 6 seconds) longer than the first opening time is set is set. The open time extension function will be described later. When the opening time extension function is not in operation, the probability that a game ball will enter the second start port 28b is low, so that the game ball will mainly enter the first start port 28a, and the design by the first special symbol Floating games are mainly performed. On the other hand, when the opening time extension function is activated, the probability that a game ball enters the second start port 28b is high, so that the game ball mainly enters the second start port 28b and the second described later. Combined with the special symbol priority variation function, the symbol variation game with the second special symbol is executed more frequently than when the opening time extension function is not activated.

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

  In this embodiment, when the opening time extending function for extending the opening time of the second start port 28b is activated, the normal symbol display section 51 displays a stop display compared to when the opening time extending function is not activated (normal time). There is a high possibility (probability) that a normal symbol to be hit will become a normal symbol display mode. That is, when the open time extension function is activated, the probability that the result of the normal symbol success / failure determination becomes a hit is higher than when the open time extension function is not activated (the probability variation function of the normal symbol success / failure determination). In the present embodiment, when the opening time extension function is activated, the fluctuation time of the normal symbol is shorter than when the opening time extension function is not activated (normal time) (normal figure fluctuation time reduction function). As a result, in this embodiment, when the open time extension function is activated, the actions of the “open time extension function”, the “normal figure fluctuation time reduction function”, and the “normal symbol success / failure probability change function” are combined. Thus, the opening frequency of the second start port 28b is improved as compared with the non-operating time (normal time) of the opening time extension function. In this way, the operation control of the “opening time extension function”, the “general symbol fluctuation time shortening function” and the “normal symbol success / failure probability fluctuation function” for improving the opening frequency of the second start port 28b is described below. This is performed by the control unit 200, and the main control unit 200 corresponds to the opening frequency improving means of the present invention.

  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.

  The determination of whether or not the normal symbol is determined, the determination of the stop symbol of the normal symbol, the setting of the variation pattern of the normal symbol, the holding of the normal symbol and the holding of the normal symbol are performed by the main control unit 200 described later.

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

  In the first special symbol display unit 61, when the game ball enters the first starting port 28a, the first special symbol starts to fluctuate, and after the predetermined time has elapsed, the first special symbol is stopped and displayed as a big hit symbol or a missed symbol. In the second special symbol display section 62, when the game ball enters the second starting port 28b, the second special symbol starts to change, and after the predetermined time has elapsed, the second special symbol is stopped and displayed as a big hit symbol or a missed symbol. Is done. In this embodiment, a plurality of jackpot symbols are set, and specifically, “probable variation jackpot symbol” and “normal jackpot symbol” are set as will be described later.

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

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

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

  The number of game balls that have entered the first start opening 28a can be held until the maximum number of reserved balls (four in this embodiment) is reached as the number of first special symbol held. The first special symbol hold number is acquired every time a game ball enters the first start port 28a and is stored in a predetermined area (first hold storage area) of the RAM of the main control unit 200. This corresponds to the number (memory number) of special symbol random numbers (first big lottery random number, first special symbol determination random number). In the present embodiment, the first special symbol determination random number is acquired together with the first big lottery random number as the game ball enters the first starting port 28a. This also corresponds to the number of symbols for design determination random numbers. The first special symbol holding number is digested and decreased by one each time the first big winning lottery is performed and the variable display of the first special symbol 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 (memory number) of special symbol random numbers (second big hit lottery random number, second special symbol determination random number). In the present embodiment, the second special symbol determination random number is acquired together with the second big hit lottery random number as the game ball enters the second starting port 28b. This also corresponds to the number of symbols for design determination random numbers. The second special symbol holding number is digested every time the second big winning lottery is performed and the variation display of the second special symbol is started, and decreases by one. The storage of the first and second special symbols and the reservation and digestion are performed by the main control unit 200 described later. For this reason, the main controller 200 corresponds to the first big hit lottery random number storage means and the second big hit lottery random number storage means of the present invention.

  In the big hit lottery random number, a hit value for determining whether or not the game is successful is set, and the big hit lottery random number acquired at the timing when the game ball enters the first start port 28a or the second start port 28b matches the win value. It is determined that it is a big hit. The first big hit lottery is performed when the first special symbol starts variable display, and the second big hit lottery is performed when the second special symbol starts variable display.

  When the first jackpot lottery random number matches the winning value, it is determined that the jackpot is successful, and the first special symbol that is stopped and displayed by the first special symbol display unit 61 is determined as the jackpot symbol. When the first big hit lottery random number does not coincide with the winning value, it is a failure, and the first special symbol that is stopped and displayed by the first special symbol display unit 61 is determined to be a loss symbol.

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

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

  The special symbol is configured to change and display according to a predetermined change pattern. This variation pattern defines the variation time of the special symbol and the presence / absence of the reach effect in the variation (effect content). The variation pattern of the special symbol is selected by lottery from a variation pattern table in which a plurality of variation patterns are stored when the big hit lottery 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). The special symbol variation pattern table used when the open time extension function is activated will be described later.

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

  Next, the jackpot game (special game) will be described. When the special symbol stopped and displayed in the special symbol display unit 61 is the above-mentioned jackpot symbol (when the result of the jackpot lottery is a jackpot), the main control unit 200 is a jackpot game that is relatively advantageous to the player ( Special game) is started. 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 big hit game process by the main control unit 200 which will be described later, and the main control unit 200 corresponds to the privilege granting means of the present invention.

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

  In the case where one round game is performed from the start to the end of the open state of the big winning opening 33a, the big hit game is ended when a predetermined number of round games are performed. In the grand prize winning device 33, after the 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 this embodiment, a plurality of maximum continuous round numbers are set. Specifically, two types of 2 rounds and 15 rounds are set as the maximum number of continuous rounds. The main control unit 200 determines the jackpot symbol of the special symbol (first special symbol, second special symbol) determined based on the special symbol determining random number (first special symbol determining random number, second special symbol determining random number). Depending on the type, the number of rounds of the jackpot game is determined. In other words, the special symbol jackpot symbol is a 15-round first jackpot game (hereinafter also referred to as “15R jackpot game”) and a two-round second jackpot game (hereinafter referred to as “15R jackpot game”). , Also referred to as “2R jackpot game”), a “2R jackpot symbol” is provided.

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

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

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

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

  In the gaming machine of this embodiment, after the big hit game 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 of the present embodiment, after the big hit game is over, a privilege game (so-called time-short game and probability variable game) in which the variable time shortening function, the open time extending function, and the probability varying function are activated is started. The variable time shortening function, the opening time extending function, and the probability varying function operate by setting the fluctuation shortening flag, the opening extension flag, and the probability changing flag to ON, respectively.

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

  Also, if the result of the big hit lottery is a big hit and the stop symbol of the special symbol is a probable big hit symbol (15R probable big hit symbol), after the big hit game ends, the probability variation function starts to operate and the probable variable game starts Is done. The probability variation game is realized by the control of the main control unit 200, and in this probability variation game, the probability that the result of the big hit lottery 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 is activated. Thus, a gaming state in which the probability variation function is activated is also referred to as a “high probability state”, and a gaming state in which the probability variation function is not activated is also referred to as a “low probability state”. In this embodiment, after the jackpot game related to the probability variation jackpot, the “high probability state” is set until the next jackpot game is started.

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

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

  Next, the variation pattern table of special symbols will be described. FIG. 3A shows an example of a first special symbol variation pattern table used when the opening time extension function is operated, and FIG. 3B is a second special symbol variation pattern used when the opening time extension function is operated. An example of a table is shown. These variation pattern tables are stored in the ROM of the main control unit 200.

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

  The three types of first special symbol deviation variation pattern tables are selected according to the number of variations of the special symbol after the opening time extension function is activated. Specifically, when the number of fluctuations of the special symbol after the start of the opening time extension function is 1 to 49, the first special symbol deviation variation pattern table A is used, and in the case of 50 times, the first special symbol variation pattern A is used. The pattern deviation variation pattern table B is used, and in the case of 51 to 100 times, the first special symbol variation pattern table C is used.

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

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

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

  The three types of variation patterns tables for the second special symbol removal are selected according to the number of variations of the special symbol after the start of the opening time extension function. Specifically, when the number of fluctuations of the special symbol after the start of the opening time extension function is 1 to 49, the second special symbol deviation variation pattern table A is used. The pattern deviation variation pattern table B is used, and in the case of 51 to 100 times, the second special symbol variation pattern pattern C is used.

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

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

  As described above, in the present embodiment, the variation mode of the first special symbol and the second special symbol is changed at a predetermined number of times (50 in the present embodiment) after the opening time extension function is activated. Then, the “special figure 1 suppression mode” in which the fluctuation display frequency of the first special symbol is low is switched from the “special figure 1 promotion mode” in which the fluctuation display frequency of the first special symbol is disadvantageous compared to the second special symbol. In the first half of the operating period of the opening time extension function (the number of special symbol fluctuations is between 1 and 49), the variation time of the first special symbol and the second special symbol is set to be short, so the second special symbol is It is difficult to increase the number of the second special symbol hold by entering a game ball into the second start opening 28b during the fluctuation display, and the digestion speed of the first special symbol hold and the second special symbol hold is high. Become. As a result, in the second half of the open time extension function operation period, the advantageous second special symbol holding number often becomes zero, and the fluctuation display of the disadvantageous first special symbol is promoted, and is often performed. Period ".

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

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

  Next, the effect symbols displayed on the effect display device 25 will be described. In the display area of the effect display device 25, an effect symbol display unit 25a for displaying effect symbols is provided. 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 design, the symbol combination with the same three digits corresponds to the jackpot symbol of the special symbol, and the other symbol combinations (that is, the non-uniform three-digit pattern corresponds to the out-of-design symbol).

  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.

  Further, in this embodiment, the background change effect, the notice effect, the reach effect, etc. are displayed on the display area of the effect display device 25 (the effect symbol display unit 25a) from when the effect symbol is started to be displayed until it is stopped. It is comprised so that various symbol fluctuation effects may be performed. While the opening time extension function is in operation, a “mode effect” corresponding to the change mode of the special symbol and a “change mode transition effect” indicating that the “special figure 1 promotion mode” is changed to the “special figure 1 suppression mode”. , "Lottery effect (disadvantage effect)" that selectively indicates whether 2R big hit game is played or 15R big hit game is performed when the special symbol is stopped and displayed with the big hit symbol, when the special symbol is stopped and displayed with the big hit symbol For example, a “15R big hit finalizing effect (advantageous effect)” or the like is executed which definitely indicates that a 15R big hit game will be played.

  Specifically, as the mode effect, during the above-mentioned “special figure 1 suppression mode”, the mode effect display “Advantageous!” Is performed on the display area of the effect display device 25 (the effect symbol display unit 25a). During the “special figure 1 promotion mode”, the mode effect display “Unfavorable!” Is performed on the display area of the effect display device 25 (the effect symbol display unit 25a). Which mode effect display is to be performed is determined based on a “command indicating a counter value of a variation pattern change counter (described later)” transmitted from the main control unit 200.

  In addition, the change mode transition effect is advantageous when changing from the “Special Figure 1 Promotion Mode” to the “Special Figure 1 Suppression Mode” (while displaying the 50th special symbol losing change during the open extension function). A mode transition effect is displayed in which a promotion effect image (in this embodiment, an effect display of “Now advantageous ...”) indicating that the player is promoted to a different situation is displayed. Whether to perform the mode transition effect is determined based on a “command indicating a counter value of a variation pattern change counter (described later)” transmitted from the main control unit 200.

  As a lottery effect, a roulette effect image (2R jackpot game of 2R jackpot game) is displayed as to whether a 2R jackpot game or a 15R jackpot game is executed when the first special symbol is stopped and displayed with a jackpot symbol while the opening extension function is operating. A selection display and a roulette effect image having a selection area of 15R jackpot game) are selectively displayed. Further, as the 15R jackpot finalizing effect, when the second special symbol is stopped and displayed with the big hit symbol during the opening extension function operation, the 15R big hit game is 100 using the roulette effect image having only the selected area of the 15R big hit game. Produce that it is executed with a probability of%.

  Next, the electronic control device of the gaming machine 1 according to the present embodiment will be described with reference to FIG. FIG. 4 is a block diagram illustrating a schematic configuration of the electronic control device.

  As shown in FIG. 4, the electronic control device includes a main control unit 200 and sub-control units 230, 260, and 280 connected to the main control unit 200. The sub control unit includes a payout control unit (prize ball control unit) 230, a sub control unit 260, and an effect display control unit 280. The main control unit 200 includes a main control board 200a, and the sub control units 230, 260, and 280 include a payout control board 230a, a sub control board 260a, and an effect display control board 280a, respectively, as peripheral control boards. Each of these control boards and other boards (a power board, a relay board, a drive board, a decoration board, an amplifier board, an effect button board, etc.) are arranged on the back side of the gaming machine 1.

  Each control unit 200, 230, 260, 280 is supplied with power from a main power source (not shown). Further, when the power is turned on, a system reset signal is transmitted to each control unit 200, 230, 260, 280.

  Next, the operation of the gaming machine 1 of this embodiment will be described based on a flowchart. FIG. 5 is an example of a main job performed under the control of the main control unit 200. The main job shown in FIG. 5 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 throw-in process (S100), each process of a game start process (S200), a normal symbol game process (S300), a normal electric game game process (S400), a special symbol game process (S500), and a big hit game process (S600) Are repeatedly executed every time the timer is reset. The power-off generation process (S50) is a power-on process (S100) when a power failure occurs due to a power failure or the like, the used registers and stack pointers are saved, the payout motor is stopped, and a system reset occurs. It has come to move to.

  The power-on process (S100) is performed when the power is turned on and when power is restored after the power is cut off. When the power is turned on, RAM initialization processing is performed, and when the power is turned off, the game state is restored when the power is turned off. Return settings etc. are made to make it happen. In the game start process (S200), detection of various switch states, update of various random numbers, prize ball payout control, and the like are performed.

  In the normal symbol game process (S300), first, the normal symbol is determined whether or not the normal symbol is displayed in the normal symbol display section 51 (see FIG. 2). The display mode is determined whether to stop display. Here, as described above, the probability of whether or not the normal symbol is correct in this embodiment is a probability of winning depending on the operating state of the opening time extension function (and the fluctuation time reduction function) that extends the opening time of the start port 28b. Are different, and the probability of hitting is higher when the open time extension function (and the variable time shortening function) is operating than when the open time extension function (and the variable time shortening function) is not operating.

  Next, when the result of determining whether or not the normal symbol is correct is obtained, the normal symbol fluctuation display time is set, and the normal symbol fluctuation display is started in accordance with the fluctuation display time. When the variable display time elapses, the normal symbol is stopped and displayed in the determined display mode, and when the normal symbol is hit and displayed in the normal symbol display mode, the operation of the normal electric accessory is started. (The second start port 28b is opened). In the normal symbol game process, the normal symbol variation display and stop display are performed as described above, and when the normal symbol is stopped and displayed in the normal symbol display mode, the second start port 28b is activated. I do. When the second start port 28b is actuated, the pair of blade pieces open to the left and right, and the second start port 28b is opened.

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

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

  First, it is determined whether or not the first start port 28a has 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 big hit lottery random number, a first special symbol random number for determining a winning symbol, 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 big hit lottery random number, a second special symbol determination random number, a reach random number, and the like. Thereby, the number of second special symbol reservation increases by one.

  Next, returning to FIG. 6A, it is determined whether or not the jackpot game is being played (whether or not the jackpot game flag is ON) (S502). As a result, when it is determined that the big hit game is being played (the big hit game flag is ON) (S502: YES), the special symbol game process is terminated and the big hit game is not being played (the big hit game flag is 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 with reference to the flowcharts of FIGS. The first special symbol variation display process and the second special symbol variation display process are processes having the same contents except for the portions of the “first special symbol” and the “second special symbol”. The “special symbol” in FIG. 4 becomes “first special symbol” in the first special symbol variation display processing, and “second special symbol” in the second special symbol variation display processing. Here, the first special symbol variation display process (S508) will be described, and the description of the second special symbol variation display process (S509) will be omitted.

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

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

  First, it is determined whether or not the result of the first big hit lottery is a big hit (S550). As a result, when it is determined that the result of the first big hit lottery is not big hit (S550: NO), it is determined whether or not the variation pattern change counter exceeds “50” (S551). The “fluctuation pattern change counter” is for counting the total number of variable display times of the first special symbol and the second special symbol performed during the operation period of the fluctuation time shortening function and the opening time extension function. At the end, an initial value (“100” in this embodiment) is set in the process of S615 described later (FIG. 10), and each time the special symbol (the first special symbol and the second special symbol) is variably displayed, the process of S527 ( The counter is configured as a countdown type counter that is subtracted in FIG. When the variation pattern change counter is updated, a variation pattern change counter specifying command indicating the counter value of the variation pattern change counter is transmitted to the sub-control unit 260 one by one (not shown).

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

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

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

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

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

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

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

  Next, according to the special symbol variation pattern set in S508d and S508e and the stop symbol determined in S508g, the first special symbol display unit 61 starts the variation display of the first special symbol (S508h), and is accompanied by this. Then, the first special symbol variation pattern designation command and the stop information designation command as the symbol variation start command are transmitted to the sub-control unit 260 (S508i). The variation pattern designation command is a command for designating the variation pattern of the first special symbol set in S508d and S508e, and the first special symbol information designation command is a command for designating the stop symbol of the first special symbol. When this variation pattern designation command and stop information designation command are transmitted to the sub-control unit 260, the symbol variation effect (effect) is controlled under the control of the sub-control unit 260 and the effect display control unit 280 that have received these commands (design variation start command). Symbol variation display) is started. Then, 1 is subtracted from the first special symbol reservation number (S508j). The above is the processing when starting the variable display of the first special symbol.

  Next, returning to FIG. 6A, if it is determined in S503 that the special symbol (the first special symbol or the second special symbol) is changing (S503: YES), the changing special symbol. It is determined whether or not the variable display time has elapsed (S510). As a result, if it is determined that the special symbol variation display time has not elapsed (S510: NO), it is determined that the special symbol game processing is terminated and the special symbol variation display time has elapsed. In 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 determined (S514: YES), it is determined whether or not the special symbol stop symbol is a big hit symbol (S515 in FIG. 6B). As a result, when it is determined that the special symbol stop symbol is a big hit symbol (S515: YES), the type of the big hit (2R big hit, 15R big hit) and the current gaming state flag are stored in the reference buffer at the time of the big hit end. The state of (probability change flag, change shortening flag, release extension flag) is set (S516).

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

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

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

  Next, in the determination process of S515, when it is determined that the special symbol stopped symbol displayed on the special symbol display unit 61 is not a big hit symbol (in other words, a symbol that is out of place) (S515: NO). Then, it is determined whether or not the release extension flag is ON (S525). As a result, when it is determined that the release extension flag is not ON (S525: NO), the special symbol game process is terminated, and when it is determined that the extension extension flag is ON (S525: YES), the release extension is performed. The count counter is decremented by 1 (S526), the variation pattern change counter is decremented by 1 (S527), and it is determined whether or not the open / extended count counter has become zero (S528).

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

  Next, the jackpot game process (S600) will be described based on the flowchart of FIG. First, it is determined whether or not the jackpot game is being played (whether or not the jackpot game flag is ON) (S601). As a result, when it is determined that the jackpot game is not being played (the jackpot game flag is OFF) (S601: NO), the jackpot game process is terminated and the jackpot game is being played (the jackpot game flag is ON). Is determined (S601: YES), it is determined whether or not the special winning opening 33a is being opened (S602). As a result, when it is determined that the special winning opening 33a is being opened (S602: YES), it is determined whether or not the opening time of the special winning opening 33a has elapsed (S603), and the special winning opening 33a is determined. When it is determined that the opening time has not elapsed (S603: NO), it is determined whether or not the specified winning number 33a has been won (whether or not the specified number of game balls have entered). (S604).

  As a result, if it is determined that the prescribed number of winnings has not been won in the big winning opening 33a (S604: NO), the jackpot game processing is terminated and the prescribed winning number has been won in the big winning opening 33a. When it is determined (S604: YES) or when it is determined that the opening time of the special winning opening 33a has elapsed (S603: YES), the special winning opening 33a is closed (S605).

  If it is determined in S602 that the special winning opening 33a is not being opened (S602: NO), it is determined whether or not the big hit game ending condition is satisfied (S606). The determination process of S606 determines whether the number of rounds of the big hit game has reached the number of rounds (15 rounds or two rounds) set at the start of the big hit game (in the process of S519 of FIG. 6B).

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

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

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

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

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

  Here, the correspondence between the processing shown in the flowcharts of FIGS. 6 to 10 and each means of the present invention will be described. The processing of S501c (FIG. 7) is the first big hit lottery random number storing means of the present invention. “S501f processing (FIG. 7)” corresponds to the second big hit lottery random number storage means of the present invention, and “S508 processing (FIGS. 6A, 8)” is the first symbol game execution means. “S509 processing (FIGS. 6A and 8)” corresponds to the second symbol game executing means, and “S506 processing (FIG. 6A)” becomes the second symbol priority changing means. Correspondingly, “processing of S601 to S609 (FIG. 10)” corresponds to the privilege granting means, “processing of S613 (FIG. 10)” corresponds to the release frequency improving means, and “processing of S552 and S555 (FIG. 9)”. "Corresponds to the variable time setting means.

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

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

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

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

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

  The five types of first special symbol removal variation pattern tables are selected according to the number of variations of the special symbol after the start of the opening time extension function. Specifically, when the number of fluctuations of the special symbol after the start of the opening time extension function is 1 to 19, the first special symbol deviation variation pattern table D is used. 1 special symbol deviation variation pattern table E is used. In the case of 40 to 59 times, the first special symbol deviation variation pattern table F is used. In the case of 60 to 79 times, the first special symbol deviation variation is used. The pattern table G is used, and in the case of 80 to 100 times, the first special symbol deviation variation pattern table H is used.

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

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

  The five types of second special symbol removal variation pattern tables are selected according to the number of variations of the special symbol after the start of the opening time extension function. Specifically, when the number of fluctuations of the special symbol after the start of the opening time extension function is 1 to 19, the second special symbol deviation variation pattern table D is used. 2 special symbol deviation variation pattern table E is used. In the case of 40 to 59 times, the second special symbol deviation variation pattern table F is used, and in the case of 60 to 79 times, the second special symbol variation fluctuation is used. The pattern table G is used, and in the case of 80 to 100 times, the second special symbol deviation variation pattern table H is used.

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

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

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

  On the other hand, when it is determined that the variation pattern change counter does not exceed “80” (S557: NO), it is determined whether or not the variation pattern change counter exceeds “60” (S559). As a result, when it is determined that the variation pattern change counter exceeds “60” (S559: YES), the number of variations of the special symbol after the start of the opening time extension function is “20” to “39”. Therefore, the first special symbol variation pattern 6 (variation time 4 seconds) is set based on the first special symbol deviation variation pattern table E (S560). In the second special symbol variation pattern setting process (S509d), the second special symbol variation pattern 6 (variation time 4 seconds) is set.

  On the other hand, when it is determined that the variation pattern change counter does not exceed “60” (S559: NO), it is determined whether or not the variation pattern change counter exceeds “40” (S561). As a result, if it is determined that the variation pattern change counter exceeds “40” (S561: YES), the number of variations of the special symbol after the start of the opening time extension function is “40” to “59”. Therefore, the first special symbol variation pattern 7 (variation time 6 seconds) is set based on the first special symbol deviation variation pattern table F (S562). In the second special symbol variation pattern setting process (S509d), the second special symbol variation pattern 7 (variation time 6 seconds) is set.

  On the other hand, when it is determined that the variation pattern change counter does not exceed “40” (S561: NO), it is determined whether or not the variation pattern change counter exceeds “20” (S563). As a result, when it is determined that the variation pattern change counter exceeds “20” (S563: YES), the number of variations of the special symbol after the start of the opening time extension function is “60” to “79”. Therefore, the first special symbol variation pattern 8 (variation time 10 seconds) is set based on the first special symbol deviation variation pattern table G (S564). In the second special symbol variation pattern setting process (S509d), the second special symbol variation pattern 8 (variation time 8 seconds) is set.

  On the other hand, when it is determined that the variation pattern change counter does not exceed “20” (S563: NO), the number of variations of the special symbol after the start of the opening time extension function is “80” to “100”. Therefore, the first special symbol variation pattern 9 (variation time 14 seconds) is set based on the first special symbol deviation variation pattern table H (S565). In the second special symbol variation pattern setting process (S509d), the second special symbol variation pattern 9 (variation time 10 seconds) is set when the number of second special symbol reservations is “0” or “1”. When the second special symbol hold number is “2” to “4”, the second special symbol variation pattern 5 (variation time 2 seconds) is set.

  In the second embodiment described above, the fluctuation time of the first special symbol and the second special symbol is increased as the number of times the first special symbol and the second special symbol are changed after the start of the opening time extension function. Is configured to become longer stepwise. As a result, during the operation of the opening time extension function, it is possible to realize a novel game progression mode in which the frequency at which the fluctuation display of the first special symbol, which is disadvantageous to the second special symbol, can be gradually suppressed can be realized. It is possible to improve the entertainment interest during the time extension function.

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

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

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

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

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

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

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

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

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

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

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

  On the other hand, when it is determined that the variation pattern change counter does not exceed “40” (S568: NO), the number of variations of the special symbol after the start of the opening time extension function is “60” to “100”. Therefore, the first special symbol variation pattern 10 (variation time 2 seconds) is set based on the first special symbol deviation variation pattern table K (S570). In the second special symbol variation pattern setting process (S509d), the second special symbol variation pattern 10 (variation time 2 seconds) is set. In the third embodiment, the variation time of the first special symbol variation pattern 10 and the second special symbol variation pattern 10 corresponds to the third variation time of the present invention, and the process of S570 executed by the main control unit 200 ( FIG. 14) corresponds to the variable time setting means of the present invention.

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

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

  For example, in each of the embodiments described above, the change start frequency of the first special symbol is changed by changing the change time of both the first special symbol and the second special symbol during the opening time extension function operation. However, the present invention is not limited to this, and the change start frequency of the first special symbol may be changed by changing only the change time of the first special symbol or only the change time of the second special symbol. . In other words, the change start frequency of the first special symbol may be changed by changing the change time of at least one of the first special symbol and the second special symbol.

  In the first embodiment, after the start of the opening time variation function, the special symbol variation time is changed when the special symbol variation count reaches 50. In the second embodiment, the opening time variation function is changed. After the activation of the variable function, the special symbol change time is changed every time the special symbol is displayed 20 times. In the third embodiment, after the start of the open time variable function, the number of changes of the special symbol is 40. It was configured to change the variation time of the special symbol at the time of reaching the time and the time of reaching 60 times, but the timing of changing the variation time of the special symbol is not limited to these time points, It can be set arbitrarily.

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

  Further, in the second embodiment, after the start of the opening time variation function, the special symbol variation time is extended stepwise every 20 times of the special symbol variation frequency, but the special symbol variation time is increased. Once extended, the special symbol variation time may be shortened, extended or maintained at random. For example, after the start of the opening time variation function, when the number of times of variation of the special symbol is 1 to 20, the variation pattern table D for the first and second special symbol removal (FIG. 11) is used, and the variation number of the special symbol is In the case of 21 to 40 times, the first and second special symbol removal variation pattern table E (FIG. 11) is used, and thereafter the variation of the special symbol every 20 times (the 40th, 60th and 80th variations). In addition, it may be switched to one of the first and second special symbol deviation variation pattern tables D to H (FIG. 11).

  In this case, the first and second special symbol deviation variation pattern tables used for the first (variation frequency 1 to 20 times) and second (variation frequency 21 to 40 times) after the start of the opening time variation function, For the first and second special symbols that are fixed in advance and used for the third (number of fluctuations 41 to 60), the fourth (number of fluctuations 61 to 80), and the fifth (number of fluctuations 81 to 100) The variation pattern table is selected at random. The change pattern of the first and second special symbol deviation variation pattern tables during the operation period of the opening time variation function is, for example, for table change acquired when the first and second special symbol deviation variation pattern tables are changed. In “Random lottery for table change” using random values, it is determined whether to change to any special symbol deviation variation pattern table, and the special symbol deviation variation pattern table to be used next is determined according to the determination result. It may be set, or according to the “table change order program” determined in advance based on the type of jackpot symbol of the special symbol that caused the opening time variation function to be started. A variation pattern table may be set.

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

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