Description

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

  Conventionally, a gaming machine equipped with a winning game that makes it difficult to enter a gaming ball into the winning prize opening by shortening the opening time of the winning prize opening (hereinafter referred to as “game per short opening”) has been known. It has been. The “game per short opening” is generally provided in order to generate a state in which it is difficult to determine the operation state (operation presence / absence) of the probability variation function without a large amount of prize ball payout. In other words, when the operation state of the probability variation function (operation presence / absence) changes with the execution of the “game per short opening”, and the operation state (operation presence / absence) of the probability variation function after the game per short release ends. By mixing the case where the same state as before the start of the game per opening is mixed, it becomes difficult for the player to determine the operating state of the probability varying function after the game per short opening. In this type of gaming machine, there is one that performs an effect suggesting the operation state of the probability variation function after the game per short opening is completed during or after the game per short opening (see Patent Documents 1 and 2). ).

JP 2010-51579 A JP 2010-200143 A

  The effects suggesting the operation state of the probability variation function described above are effect devices (effect display devices, movable decorative bodies, decorative lamps, etc.) provided on the game board surface or the gaming machine frame in order to realize various effects as the game progresses. ) Is generally used. However, the playability of performing an effect suggesting the operating state of the probability variation function by such an effect device is becoming rutted now. For this reason, it becomes difficult to improve the gaming interest of a gaming machine (a so-called “latency probability changing function”) that makes it difficult to determine the operating state of the probability variation function after the game per short opening. ing.

  Therefore, in view of the above points, the present invention aims to improve the gaming interest by realizing novel gaming characteristics in a gaming machine in which it is difficult to determine the operating state of the probability variation function after the game is finished per short opening. Objective.

In order to achieve the above object, the gaming machine of the present invention provides:
A game per long opening that opens a large winning opening multiple times based on a long opening time that makes it easy to enter a game ball and a large winning opening that opens multiple times based on a short opening time that makes it difficult to enter a game ball Per game execution means capable of executing a game per short opening;
Lottery means for performing a lottery on whether or not to execute the winning game;
A probability setting means for setting the winning probability of the lottery to a normal probability or a high probability higher than the normal probability,
A game per first short opening and a game per second short opening are set as the games per short opening,
The probability setting means includes:
When the game per first short opening is executed, the winning probability of the lottery performed after the game per first short opening ends is set to a high probability, and the game per second short opening is executed. And a gaming machine that sets the winning probability of the lottery performed after the second short opening game ends to the same probability or the normal probability as before the start of the second short opening game,
Execution pattern storage means for storing a plurality of execution patterns having different execution timings of the final opening / closing operation among the plurality of times as an execution pattern of the opening / closing operation of the big prize opening in the game per short opening;
When executing the game per short opening, the execution pattern of the opening / closing operation of the big prize opening used in the game per short opening is selected from a plurality of execution patterns stored in the execution pattern storage means according to a predetermined selection condition Execution pattern selection means to perform,
As the selection condition, a first selection condition in which a selection rate of an execution pattern having a late execution timing of the final opening / closing operation is set higher than a selection rate of an execution pattern having an early execution timing of the final opening / closing operation, and A selection condition storage means for storing a second selection condition in which a selection rate of an execution pattern having an early execution timing of the final opening / closing operation is set higher than an selection pattern of an execution pattern having a late execution timing of the final opening / closing operation; With
When the game per short opening to be executed is the game per first short opening, the execution pattern selecting means selects the execution pattern of the opening / closing operation of the big prize opening used in the game per first short opening. When the game per short opening that is selected and executed based on the first selection condition is the game per second short opening, execution of the opening / closing operation of the big prize opening used in the game per second short opening A pattern is selected based on the second selection condition.

  As described above, a plurality of execution patterns with different execution timings of the final opening / closing operation are provided as execution patterns of the opening / closing operation of the prize winning opening, and a plurality of selection conditions with different selection rates of the respective execution patterns are set per game of short opening By using according to the type, the execution timing of the final opening / closing operation of the big prize opening differs depending on the type of game per short opening. As a result, the player pays attention to the opening / closing operation of the big prize opening during the game per short opening, and based on the opening / closing operation of the big winning opening, the probability variation function after the game per short opening is finished. It is possible to realize a new gameability in which the operating state can be estimated.

  Here, “execution timing of opening / closing operation of the grand prize opening” means the timing of performing the “opening operation” in which the grand prize opening in the closed state is opened or the grand prize opening in the open state is closed. This refers to the time when “closing operation” is performed. For example, when the opening / closing operation of the grand prize opening is performed once in one round in the winning game, the “opening start timing” and “opening end timing (closing timing)” in the single opening / closing operation are “large”. This corresponds to “execution timing of opening / closing operation of winning opening”. In addition, when the opening / closing operation of the grand prize opening is performed a plurality of times in one round in the winning game, each “opening start timing” and “opening end timing (closing timing)” in the multiple opening / closing operations are This corresponds to “Execution timing of opening / closing operation of big prize opening”.

  The configuration in which the execution timing of the final opening / closing operation of the grand prize opening is different from each other is, for example, that the “first opening start timing of the big prize opening” in each of the execution patterns is the same, and “the opening of the big prize opening” This can be realized by making at least one of “long or short” or “long or short closing time of the big prize opening” different for each execution pattern. Alternatively, “the final opening start timing of the big prize opening” is different from each other, and “the order of the first opening start timing of the big winning opening” and “the final opening start timing of the big prize opening” in each execution pattern The reverse of the `` order '', i.e., when the first opening start timing of the big prize opening is early, the final opening start timing is late, and when the first opening start timing of the big prize opening is late, the final opening By making the opening start timing earlier, the execution timing of the final opening / closing operation of the special winning opening can be made different from each other. In addition, “the final opening opening timing (closing timing) of the final winning opening” is different from each other, “the order of the first opening start timing of the large winning opening” and “the final opening of the large winning opening” in each execution pattern In the execution pattern with the first opening start timing of the big prize opening being early, the final opening end timing is late and the first opening start timing of the big winning opening is late. Then, it is possible to make the final opening / closing operation timing different from each other by making the final opening end timing earlier.

  In these configurations, “the first opening start timing of the grand prize opening” and “the execution timing of the final opening / closing operation of the big winning opening” are not related, and “the first opening start timing of the big winning opening” It becomes difficult to estimate the “execution timing of the final opening / closing operation of the big prize opening”. For this reason, it is difficult to recognize whether the execution timing of the final opening / closing operation of the big winning opening is “early” or “slow” until the final opening / closing operation of the big winning opening in the game per short opening is performed. It becomes. As a result, it is possible to maintain the player's expectation for the operation of the probability variation function until the final opening / closing operation of the big winning opening in the game per short opening is performed. It is possible to effectively realize the gameability in which the operating state of the probability variation function after the game ends per short opening can be estimated based on the final opening / closing operation of the winning opening.

In addition, the gaming machine of the present invention,
With the effect execution means for performing a predetermined short open per game effects during the previous SL short open per game,
The game effect per short opening is configured such that the content changes according to the progress of the effect,
Furthermore, the game effect per short opening starts before the game per short opening and ends after the game per short opening, and is thereby defined by each of the plurality of execution patterns. The execution timing of the final opening / closing operation is set from the start to the end of the game effect per short opening and is different from each other .

As a result, the player can recognize at which stage the progress status of the game per short opening is currently based on the content (effect progress status) of the game effect per short opening being executed. Therefore, for the player, paying attention to the opening / closing operation of the big prize opening in the game per short opening and the game production per short opening , the final opening / closing operation of the big winning opening ends from the start of the game per short opening It becomes easy to recognize at which stage until. As a result, based on the final opening / closing operation of the big prize opening during the game per short opening, it is possible to infer the type of game per short opening, that is, the operation state of the probability variation function after the game per short opening ends. Can be effectively realized.

In addition, the gaming machine of another invention related to the present invention is:
The game per second short opening is a probability maintaining game per short opening in which the winning probability of the lottery after the game per second short opening ends is set to the same probability as before the game per second short opening. And a normal probability per short opening game in which the winning probability of the lottery after the second short opening game is finished is set to the normal probability,
The selection condition storage means stores a third selection condition in which a selection rate of an execution pattern with an early execution timing of the final opening / closing operation is set higher than the second selection condition,
When the second short-open game to be executed is the probability-maintaining short-open game, the execution pattern selection means executes the execution pattern of the opening / closing operation of the big prize opening used in the probability-maintaining short-open game. Is selected according to the second selection condition, and the game executed per second short opening is the normal probability short opening per game, the opening / closing of the big prize opening used in the normal probability short opening per game The execution pattern of the operation is selected according to the third selection condition.

  In this way, by using different selection conditions for selecting the execution pattern of the big prize opening / closing operation in the “probability maintaining short opening per game” and the “normal probability short opening per game” which are the games per second short opening, For the player, based on the final opening / closing operation timing of the big winning opening during the game per short opening, the “probability maintaining short opening per game” and the “normal probability short opening per game” should be distinguished Is possible. As a result, even when the “probability maintaining short release per game” or “normal probability short release per game” is started during the operation of the probability change function, the operation state of the probability change function after the short release per game ends. Can be inferred based on the final opening / closing operation of the special winning opening.

  According to the configuration of the present invention described above, in the gaming machine in which it is difficult to determine the operation state of the probability variation function after the game per short release is completed, the operation state of the probability variation function after the game per short release is terminated. Can be inferred based on the opening / closing operation of the big prize opening during the short-open game, thereby improving the game entertainment.

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 operation gate 27, and after the predetermined time has passed, the normal symbol hits in the normal symbol display mode or the off-normal symbol display mode. Stopped display. When the normal symbol is stopped and displayed in the preset normal symbol display mode, the second start port 28b is opened according to a predetermined opening pattern. A plurality of opening patterns of the second start port 28b are set. When the opening time extending function for extending the opening time of the second start port 28b is not in operation (normal time), a first opening pattern (short-time opening pattern) in which a first opening time (for example, 0.5 seconds) is set. ) Is set, and when the open time extension function is activated, a second open pattern (long open pattern) in which a second open time (for example, 4 seconds) longer than the first open time is set is set. The open time extension function will be described later.

  In the present embodiment, 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.

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

  It should be noted that the determination of whether or not the normal symbol is determined, the determination of the stop symbol of the normal symbol, the setting of the variation pattern of the normal symbol, the storage and storage of the normal symbol are performed by the main control unit 200 described later.

  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.

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

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

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

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

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

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

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

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

  The special symbol is configured to change and display according to a predetermined change pattern. This variation pattern defines the variation time of the special symbol and the presence / absence of the reach effect in the variation (effect content). The special symbol variation pattern is selected by lottery using a variation pattern random number from a variation pattern table in which a plurality of variation patterns are stored when the special symbol success / failure determination is executed.

  A plurality of special symbol variation pattern tables are prepared, and each is selected and used according to the gaming state (special symbol variation mode). In these multiple variation pattern tables, “High probability shortening” is selected in the high probability shortening variation state (high probability shortening variation mode) in which all of the probability variation function, variation time shortening function, and open time extension function are operating. "Fluctuation pattern table", "High probability normal fluctuation pattern table" selected in the high probability normal fluctuation state (high probability normal fluctuation mode) in which only the probability fluctuation function is operating, and the fluctuation time when the probability fluctuation function does not operate The low probability shortening variation pattern table selected in the low probability shortening variation state in which the shortening function and the open time extension function are activated, and the probability variation function, the variation time shortening function, and the open time extension function are all in operation. A “low probability normal variation pattern table” selected in a low probability normal variation state (low probability normal variation mode) is included.

  Each variation pattern table selected according to the gaming state includes a hit variation pattern table selected when the result of the special symbol success / failure determination is a win (big hit or small hit) and the result of the special symbol success / failure determination. A deviation variation pattern table selected in the case of deviation is included. The deviation variation patterns stored in the deviation variation pattern table include a “normal deviation variation pattern (reach variation pattern without reach)” that does not involve reach variation and a “reach variation pattern with reach” that involves reach variation. The normal deviation variation pattern is configured as a variation pattern with a shorter special symbol variation time than the reach deviation variation pattern. The reach variation variation pattern has a special symbol variation time longer than the normal variation variation pattern. It is configured as. The presence or absence of reach variation is determined by lottery using a reach random number acquired when the game ball enters the start port 28.

  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 is preferentially displayed in a variable manner over the first special symbol. The reservation of the symbol is preferentially consumed. When the first special symbol reservation count is “1 or more” and the second special symbol reservation count is “zero”, the variable display of the first special symbol is executed.

  First special symbol success / failure determination, second special symbol success / failure determination, determination of variation mode (variation pattern) of first special symbol, determination of variation mode (variation pattern) of second special symbol, stop of first special symbol Determination of symbol, determination of stop symbol of second special symbol, change display and stop display of first special symbol, change display and stop display of second special symbol, priority change of second special symbol will be described later. 200.

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

  During the big hit game, the big prize device 33 is operated, and a predetermined number of prize balls (for example, 15 prize balls for one prize) according to the number of game balls entered into the big prize opening 33a. Will be paid out. 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, the number of game balls entered when the opening time of the special winning opening 33a reaches a specified time (30 seconds or 0.1 second in this embodiment) or when the special winning opening 33a is in an open state. It may be when the specified number (10 in this embodiment) is reached.

  In the case where one round game is performed from the start to the end of the open state of the big winning opening 33a, the big hit game is ended when a predetermined number of round games are performed. In the grand prize winning device 33, after the special prize opening 33a has been opened, that is, after a predetermined time has elapsed since the big prize winning opening 33a is closed, the big prize winning opening 33a is again opened and the next round game starts. To do. The opening / closing operation of the grand prize opening 33a in which one round game is from the start to the end of the big prize opening 33a is repeated until a predetermined maximum number of consecutive rounds (15 rounds in this embodiment) is completed. .

  In the gaming machine 1 of this embodiment, two types of big hit games are provided, and when the result of the special symbol success / failure determination is “first big hit”, the “first big hit game” is started, and the special symbol success / failure determination is performed. When the result is “second big hit”, “second big hit game” is started. These first and second big hit games differ in the opening time (specified time) of the big winning opening 33a in one round. Specifically, in the “first big hit game”, the opening time of the big winning opening 33a is set to the long opening time, and in “second big hit game”, the opening time of the big winning opening 33a is set to the short opening time. .

  The opening time of the first jackpot game big winning opening 33a (the first big hit game big winning opening opening time) is a prescribed number (10) of entering the big winning opening 33a and the execution of the winning ball payout associated therewith. It is set as a time when the possibility becomes extremely high, that is, a time when the prize ball payout amount increases, and is set to 30 seconds in this embodiment. The opening time of the big winning hole 33a for the second big hit game (the big winning hole opening time for the second big hit game) is a specified number (10) of the balls to the big winning hole 33a and the execution of the winning ball payout associated therewith. It is set as the time when the possibility becomes extremely low, that is, the time when the prize ball payout amount decreases (including the time when the prize ball payout amount becomes substantially zero), and is set to 0.1 second in this embodiment. Has been. Due to the difference in opening times of these big winning holes 33a, the first big hit game is positioned as a “long open per game” that makes it easy to enter the game ball, and the second big hit game is a game of the game ball together with the small hits described later. It is positioned as a “game per short opening” that makes entry difficult.

  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 type of jackpot game is determined. That is, the special symbol jackpot symbol is provided with a “first jackpot symbol” that generates a first jackpot and a “second jackpot symbol” that generates a second jackpot. In this embodiment, the probability variation function is activated after the first jackpot game is finished, and the probability variation function is activated after the second jackpot game is finished. A special symbol (first special symbol) determined based on a special symbol determining random number (a first special symbol determining random number, a second special symbol determining random number) is provided, which is a big hit "second probable big hit". Whether or not the probability variation function is to be activated is determined after the end of the jackpot game according to the type of the jackpot symbol of the second special symbol). That is, for the special symbol jackpot symbol, the “first probability variable jackpot” that will generate “first probability variation jackpot” and the “second probability variation jackpot” that will generate “second probability variation jackpot”. In addition, there is provided a “first normal big hit symbol (hereinafter also referred to as a normal big hit symbol)” that generates a “first normal big hit” in which the probability variation function does not operate after the end of the first big hit game. .

  In the gaming machine of the present embodiment, after the big hit game is finished, a specific game (so-called short-time game and probability variable game) in which the variable time shortening function, the open time extending function and the probability varying function are activated is started. The variable time shortening function, the opening time extending function, and the probability varying function operate by setting the fluctuation shortening flag, the opening extension flag, and the probability changing flag to ON, respectively. The variable time shortening function and the open time extending function start simultaneously and end simultaneously. In the following description, when only one of the functions related to the operating state of the variable time shortening function and the open time extending function is described, the other function is also paired. For example, when it is described in the following description that “the variable time shortening function is operating”, this description can be interpreted as “the opening time extending function is also operating”. When it is described that “the function is operating”, this description can be understood as “the variable time reduction function is operating”.

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

  When the result of the special symbol success / failure determination is a big hit, and the stop symbol of the special symbol is the first positive variation big hit symbol (the big hit type is the first positive variable big hit), the variable time shortening function and the release are made after the first big hit game ends. In addition to the time extension function, the probability variation function is activated and the probability variation game is started. The probability variation game is realized by the control of the main control unit 200. In this probability variation game, the probability that the result of the special symbol success / failure determination is a big hit, that is, the probability that the special symbol is stopped and displayed with the big hit symbol is changed (improved). The probability variation function (special symbol probability variation means) is activated.

  While the probability variation function is in operation, the probability that the result of the special symbol success / failure determination is a jackpot is improved by increasing the jackpot value for the determination of success / failure. Specifically, a normal probability success / failure determination table and a high probability success / failure determination table in which the number (type) of jackpot values is larger than the normal probability success / failure determination table are prepared. During normal games (when the probability variation function is inactive), the normal probability determination table is used to determine whether or not, and during probability change games (when the probability variation function is in operation), a high probability determination table is used. Make a pass / fail decision. Selection of these success / failure determination tables (setting of the winning probability of special symbol success / failure determination) is performed by the main control unit 200. For this reason, the main control unit 200 corresponds to the “probability setting means” of the present invention.

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

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

  Next, the small hit game which is one mode of the hit game will be described. When the special symbol stopped and displayed on the first special symbol display unit 61 or the second special symbol display unit 62 is a small hit symbol (when the result of the special symbol determination is a small hit), the main control unit 200 Starts a small hit game. The small hit game is a hit game that starts by setting the small hit game flag to ON.

  In the small hit game, the big prize device 33 operates in the same manner as the second big hit game described above. In other words, in the small hit game, the large winning opening 33a is configured to open 15 times every 0.1 second, and the possibility that a game ball will enter the large winning opening 33a is very low, so that the payout of the winning ball is substantially reduced. It is in a gaming state that does not accompany. Thus, the small hit game constitutes a “short open hit game” together with the above-mentioned second big hit game. Of the games per short opening, the second probability large hit game corresponds to the “first short opening per game” of the present invention, and among the games per short opening, the small per game is the “second short opening per game” of the present invention. It corresponds to.

  In addition, after the small hit game ends, the game state at the start of the small hit game (when the small hit symbol is stopped and displayed) (the operating state of the variable time reduction function, the open time extension function, the probability variable function) is maintained. The For this reason, in the normal gaming state in which the probability variation function is not activated, when the second probability variation big hit occurs, the probability variation function starts operating after the winning game ends, whereas in the case where a small hit occurs The probability variation function does not start after the winning game ends. Due to the operation state of the probability varying function after the end of the hit game, the second probability variation big hit game becomes a hit game that is more advantageous to the player than the small hit game.

  Since the operation of the big winning device 33 is the same in the second big hit game and the small hit game, for the player, the execution pattern of the short opening / closing operation of the big winning opening 33a (second big win game or Even if the small winning game big winning opening / closing pattern is recognized, it is difficult (impossible) to accurately distinguish whether the second big winning game or the small winning game has occurred. This makes it difficult to determine whether or not the probability varying function is activated after the operation of the big winning device 33 is finished (after the second big hit game or the small hit game is finished). A state in which it is difficult to determine whether or not the probability variation function is operating is referred to as a “probability non-notification state” or a “latency probability variation state (internal probability variation state)”.

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

  Here, the opening / closing pattern of the big winning opening 33a in the short opening per game (second probability variation big hit game and small hit game) will be described based on FIG. 3 and FIG.

  FIG. 3 is a timing chart showing an execution pattern (second big winning big opening opening / closing pattern and small winning big opening opening / closing pattern) of the opening / closing operation of the big winning opening 33a of the game per short opening. As shown in FIG. 3, in the short opening per game (second probability variation big hit game and small hit game) of this embodiment, the execution timing of the final opening / closing operation of the big winning opening 33a is different (in this embodiment, Four) big prize opening / closing patterns A to D are provided. These special winning opening opening / closing patterns are stored in the ROM of the main control unit 200. For this reason, the main control unit 200 corresponds to the “execution pattern storage unit” of the present invention.

  In the multiple winning opening / closing patterns A to D of the present embodiment, the opening start timing of the first winning opening 33a is the same (first time), and the final opening of the winning opening 33a (the 15th time). The execution timing of the opening / closing operation is different. Specifically, the opening timing of the final winning opening 33a is the earliest in the winning opening opening / closing pattern A, and the winning opening opening / closing pattern B, the winning opening opening / closing pattern C, and the winning opening opening / closing pattern D are in this order. It ’s late.

  In the present embodiment, the opening times of the special winning opening 33a are the same and the closing times (interval times) of the special winning opening 33a are different in each of the special winning opening / closing patterns A to D. Specifically, the total closing time (total closing time) of the special winning opening 33a from the start to the end of the game per short opening is the shortest winning opening opening / closing pattern A, the big winning opening opening / closing pattern B, and the big winning prize. The opening / closing pattern C and the special winning opening / closing pattern D are longer in this order. Thereby, the final opening start timing of the special winning opening 33a in the special winning opening / closing patterns A to D is varied. In this embodiment, the opening timings of the final winning opening 33a are different in each of the winning opening / closing patterns A to D, but the opening times of the winning openings 33a in each pattern are the same. The opening start timing of the first big winning opening 33a is different, and the opening end timing (closing timing) of the final winning opening 33a is also different for each pattern. That is, in this embodiment, both the “opening start timing” and the “opening end timing (closing timing)” in the final opening / closing operation of the big winning opening 33a are different. Execution timing of each opening / closing operation "is different for each winning prize opening / closing pattern (execution pattern).

  FIG. 4 is a table for selecting a winning opening / closing pattern selection table for a game per short opening, and FIG. 4A is a first pattern selection for selecting a winning opening opening / closing pattern for a second probability variation big hit game used in the second probability variation big hit game. Tables (first selection conditions) and (b) are second pattern selection tables (second selection conditions) for selecting a big winning opening / closing pattern for small hits used in the small hit game. These pattern selection tables are stored in the ROM of the main control unit 200. Therefore, the main control unit 200 corresponds to the “selection condition storage unit” of the present invention.

  As shown in FIG. 4 (a), the first pattern selection table used when the second probability variation jackpot has occurred has a 5% probability that the winning opening opening / closing pattern A is selected, and the winning opening opening / closing pattern B is The probability of being selected is 15%, the probability of selecting the special prize opening / closing pattern C is 30%, and the probability of selecting the special prize opening / closing pattern D is 50%. That is, when the second probability variation jackpot occurs, the probability that the winning opening opening / closing pattern A with the early execution timing of the opening / closing operation of the winning opening 33a is selected is the lowest, and the final opening of the winning opening 33a The probability of selecting the special winning opening / closing pattern D with the slow execution timing of the opening / closing operation is set to be the highest.

  Also, as shown in FIG. 4B, the second pattern selection table used when a small hit occurs has a 50% probability that the big prize opening / closing pattern A is selected, and the big prize opening / closing pattern B is The probability of being selected is 30%, the probability of selecting the special winning opening / closing pattern C is 15%, and the probability of selecting the special winning opening / closing pattern D is 5%. In other words, when a small hit occurs, the probability that the winning opening opening / closing pattern A having the earliest execution timing of the opening / closing operation of the winning winning opening 33a is the highest is selected, and the opening / closing of the winning opening 33a is the final opening / closing. The probability of selecting the special winning opening / closing pattern D with the slow execution timing of the operation is set to be the lowest.

  In this embodiment, selection of the special winning opening / closing pattern is performed by random number lottery. Specifically, the selection rate of the first pattern selection table shown in FIG. 4A is set by a random number range (winning value) corresponding to each of the winning prize opening / closing patterns A to D. Similarly, FIG. The selection rate of the second pattern selection table shown in 4 (b) is set by a random number range (winning value) corresponding to each of the big winning opening / closing patterns A to D. Then, by performing random lottery using these lottery tables, a specific special winning opening / closing pattern is selected. It should be noted that the main control unit 200 selects a special winning opening / closing pattern (execution pattern of the opening / closing operation of the special winning opening) using the pattern selection table. Therefore, the main control unit 200 corresponds to the “execution pattern selection unit” of the present invention.

  In the present embodiment having the above-described configuration, when the second probability variation big hit game is executed, the big winning opening / closing pattern with the slow execution timing of the final opening / closing operation of the big winning opening 33a is the large winning opening 33a. Based on the “first pattern selection table (first selection condition)” that is easier to select than the big winning opening opening / closing pattern with the early execution timing of the opening / closing operation, the big winning opening opening / closing pattern is selected. On the other hand, when a small hit game is executed, the big winning opening / closing pattern with the early execution timing of the final opening / closing operation of the big winning opening 33a is late in the execution timing of the final opening / closing operation of the big winning opening 33a. Based on the “second pattern selection table (second selection condition)” that is easier to select than the big winning opening / closing pattern, the big winning opening / closing pattern is selected. As a result, as the execution timing of the final opening / closing operation of the big winning opening 33a in the game per short opening (in this embodiment, at least “opening end timing (closing timing)” is delayed, the game per short opening is “ There is a high possibility that the game is a “second probability variable big hit game”, and the earlier the opening / closing operation timing of the large winning opening 33a during the short open game is, the earlier the short open game is “small hit game”. The possibility increases.

  As described above, when the second probability variation jackpot game is executed, the probability variation function operates after the second probability variation jackpot game ends, regardless of the operation state of the probability variation function at the start of the second probability variation jackpot game. When a small hit game is executed, if the probability variation function is not activated at the start of the small hit game, the probability variation function does not operate after the small hit game ends, and the probability variation function is activated at the start of the small hit game. If so, the probability variation function will operate even after the small hit game ends. For this reason, based on the execution timing of the final opening / closing operation of the big winning opening 33a during the game per short opening, it becomes possible to estimate the operating state of the probability varying function after the game per short opening.

  Further, in this embodiment, after the short opening per game (second probability variable big hit game or small hit game) is finished, the player's expectation for the operation of the probability changing function is inferred while the operating state of the probability changing function is unknown. It becomes a “special game state” in which the symbol variation effect is performed in the special effect mode. And during execution of the game per short opening, the mode transition effect (special game transition effect) which alert | reports shifting to a special game state (special effect mode) is performed. The mode transition effect may be performed by displaying a specific symbol in the display area of the effect display device 25, or may be performed by outputting sound from the speakers 10a to 10d. Note that the special effect mode and the mode transition effect are realized by the control of the sub-control unit 260. For this reason, the sub-control unit 260 corresponds to the “production execution means” of the present invention.

  As shown in FIG. 3, the mode transition effect (special game transition effect) starts before the game per short opening and ends after the game per short opening. Thus, the “execution timing of the final opening / closing operation of the big winning opening 33a” defined by the respective big winning opening / closing patterns A to D of the short opening per game (second probability variation big hit game or small hit game), that is, In the present embodiment, both the “opening start timing” and the “opening end timing (closing timing)” of the final winning opening 33a are set between the start and end of the mode transition effect.

  In addition, the mode transition effect is configured so that the content changes according to the progress of the effect, and the stage transition per short-open game is recognized by the content of the mode transition effect (effect progress status). can do. For this reason, for the player, by paying attention to the “mode transition effect” and the “opening operation of the big prize opening 33a” during the execution of the game per short opening, at which stage from the start to the end of the game per short opening It becomes easy to recognize whether the “opening / closing operation of the final winning opening 33a”, that is, “the opening of the final opening” or “the opening of the final opening (closing)” has been performed. It becomes easy to guess the operating state of the probability variation function after the completion.

  Next, the effect symbols displayed on the effect display device 25 will be described.

  Next, the operation of the gaming machine 1 of this embodiment will be described based on a flowchart. FIG. 6 is an example of a main job performed under the control of the main control unit 200. The main job shown in FIG. 6 is executed by the CPU 200b mounted on the main control board 200a in accordance with a program stored in a ROM (not shown) (an internal ROM of the CPU 200b or a ROM mounted on the main control board 200a). After the 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, etc. are performed. In the normal symbol game process (S300), first, the normal symbol display part is determined. At 51 (see FIG. 2), it is determined whether the normal symbol is hit and stopped in the display mode of the normal symbol or whether it is stopped and displayed in the display mode of the off-normal symbol. Here, as described above, the normal symbol success / failure determination in the present embodiment has a probability of being hit according to 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. There is a difference that the probability of hitting is higher when the open time extension function (and variable time reduction function) is activated than when the open time extension function (and variable time reduction function) is not active.

  Next, when the result of normal symbol success / failure determination is obtained, the variation time of the normal symbol is set, and the variation display of the normal symbol is started according to the variation time. When the fluctuation time elapses, the normal symbol is stopped and displayed in the determined display mode, and when the normal symbol is stopped and displayed in the normal symbol display mode, the operation of the normal electric accessory is started. (The 2nd starting port 28b is made into an open state). In the normal symbol game process, the normal symbol variation display and stop display are performed as described above, and when the normal symbol is stopped and displayed in the normal symbol display mode, the second start port 28b is activated. I do. When the second start port 28b is actuated, the pair of blade pieces open to the left and right, and the second start port 28b is opened.

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

  Next, the special symbol game process (S500) will be described based on the flowcharts of FIGS. First, as shown in FIG. 7A, a start opening winning process is performed (S501). Here, the start opening winning process (S501) will be described based on the flowchart of FIG.

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

  Next, it is determined whether or not the second start port 28b has been won (S501d). If it is determined that the second start port 28b has not been won (S501d: NO). The start opening winning process is terminated. On the other hand, if it is determined that the second start port 28b has been won (S501d: YES), it is determined whether or not the second special symbol hold number is less than 4 (S501e). As a result, when it is determined that the second special symbol hold number is not less than 4 (4 or more) (S501e: NO), the start opening winning process is terminated, and the second special symbol hold number is less than 4. If it is determined that there is (S501e: YES), a second special symbol random number (second symbol success / failure determination information) is acquired and stored (S501f). The second special symbol random number includes a second special symbol determination random number, a second special symbol determination random number (per 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. 7A, it is determined whether or not a hit game is being performed (whether the big hit game flag or the small hit game flag is ON) (S502). As a result, when it is determined that a hit game is being played (a big hit game flag or a small hit game flag is ON) (S502: YES), the special symbol game process is terminated and no hit game is being played (a big win game) If it is determined that the flag and the small hit game flag are OFF) (S502: NO), it is determined whether or not the special symbol (the first special symbol or the second special symbol) is changing (S503). ).

  As a result, when it is determined that the special symbol is changing (S503: YES), the process proceeds to S510 described later, and when it is determined that the special symbol is not changing (S503: NO). Then, it is determined whether or not it is during the special symbol stop display time (S504). Here, the stop display time of the special symbol is a time for determining the special symbol stopped and displayed. In this embodiment, the stop display time of the special symbol is “1 second”. If it is determined that it is during the special symbol stop display time (S504: YES), the process proceeds to S514 described later, and if it is determined that it is not during the special symbol stop display time (S504). : NO), it is determined whether or not the number of second special symbol hold is zero (S506). As a result, when it is determined that the number of second special symbol reservation is zero (S506: YES), it is determined whether or not the number of first special symbol reservation is zero (S507).

  And when it determines with the 1st special symbol holding | maintenance number being zero (S507: YES), a special symbol game process is complete | finished. On the other hand, when it is determined that the number of first special symbol hold is not zero (S507: NO), a first special symbol variation display process is performed (S508).

  On the other hand, if it is determined in S506 that the second special symbol hold count is not zero (S506: NO), a second special symbol variation display process is performed (S509). That is, if it is determined in the determination process of S506 that the second special symbol hold number is not zero (S506: NO), the first special symbol hold number is not zero (even if it is 1 or more). 2. The special symbol variation display process is executed. Thereby, the variation display of the second special symbol is performed in preference to the first special symbol, and the priority variation function of the second special symbol is realized by the determination processing in S506.

  Here, the first special symbol variation display process (S508) and the second special symbol variation display process (S509) will be described based on the flowchart of FIG. The first special symbol variation display process and the second special symbol variation display process are processes having the same contents. That is, the “special symbol” in FIG. 9 becomes “first special symbol” in the first special symbol variation display process, only “second special symbol” in the second special symbol variation display process, and the others are the same. is there. Hereinafter, the first special symbol variation display process (S508) will be described, and the description of the second special symbol variation display process (S509) will be omitted.

  First, the random number for determining whether or not the special symbol is stored in a predetermined area (holding storage area) of the RAM of the main control unit 200 (the random number for determining whether or not the game ball has entered the start opening 28) is read (S508a). ), Special symbol winning / failing determination is performed (S508b). In the special symbol success / failure determination, when the probability variation function is in operation (probability change game), it is determined whether the determination result is a big hit (high probability state) using the high probability determination table. If it is determined that the probability variation function is not in operation (in normal game), the normal probability determination table is used to determine whether the determination result is a big hit (low probability state). Make a decision.

  Next, it is determined whether or not the result of the special symbol success / failure determination (S508b) is a big hit (S508c). As a result, when it is determined that it is a big hit (S508c: YES), a big hit hour variation pattern table setting process is performed (S508d). On the other hand, when it is determined that it is not a big hit (S508c: NO), a small hit determination is further performed to determine whether or not the result is a small hit (S508e). As a result, when it is determined that the game is a small hit (S508e: YES), a small hit hour variation pattern table setting process is performed (S508f). On the other hand, when it is determined that it is not a small hit (S508e: NO), a variation pattern table setting process at the time of disconnection is performed (S508g).

  Next, the variable pattern random number is acquired, and the symbol determining random number (the special symbol determining random number acquired when the game ball enters the starting port 28) stored in a predetermined area of the RAM of the main control unit 200. Read (S508h).

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

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

  Next, returning to FIG. 7A, if it is determined in S503 that the special symbol (the first special symbol or the second special symbol) is changing (S503: YES), the changing special symbol. It is determined whether or not the variable display time has elapsed (S510). As a result, if it is determined that the special symbol variation display time has not elapsed (S510: NO), it is determined that the special symbol game processing is terminated and the special symbol variation display time has elapsed. In this case (S510: YES), the special symbol variation display is stopped (S511), and a special symbol designating command indicating that the special symbol variation display is stopped is transmitted to the sub-control unit 260 (S512). A stop display time is set (S513).

  Next, it is determined whether or not the special symbol stop symbol display time has elapsed (S514). As a result, when it is determined that the special symbol stop symbol display time has not elapsed (S514: NO), the special symbol game processing is terminated and it is determined that the special symbol stop symbol display time has elapsed. If it is (S514: YES), the stop symbol of the special symbol stopped and displayed on the first special symbol display unit 61 or the second special symbol display unit 62 is a winning symbol (big hit symbol or small hit symbol) Is determined (S515 in FIG. 7B). As a result, when it is determined that the stop symbol of the special symbol is a winning symbol (S515: YES), the type of current hit and the current gaming state flag (probability change flag) are stored in a predetermined area of the RAM of the main control unit 200. , Fluctuation shortening flag, release extension flag) state and the like are stored (S516).

  Next, it is determined whether or not the winning symbol stopped and displayed on the first special symbol display unit 61 or the second special symbol display unit 62 is a small hit symbol (S517). As a result, when it is determined that the winning symbol that has been stopped is not a small symbol (S517: NO), it is further determined whether or not the symbol that has been stopped is the second big symbol (S518). ). As a result, when it is determined that the winning symbol that is stopped is not the second big winning symbol, that is, when the winning symbol that is stopped and displayed is the first positive variation big winning symbol or the first normal big winning symbol (S518: NO) ), And selects and sets the first big hit prize opening opening / closing pattern (S519). The first big hit opening / closing pattern for the big hit is an opening / closing pattern for performing 15 rounds (15 times) of opening / closing operation in which the opening time of the big winning opening 33a is set to 30 seconds per round. This is an opening / closing pattern in which the possibility of entering a specified number (10) into 33a and the possibility of winning a prize ball payout is extremely high, and the amount of prize ball payout increases (opening and closing of the "first big hit game" above) pattern).

  On the other hand, when it is determined that the winning symbol displayed in a stopped state is the second big hit symbol (S518: YES), the second big hit symbol is obtained by random number lottery using the first pattern selection table shown in FIG. The big prize opening / closing pattern is selected and set (S520). Then, the big hit game flag is set to ON (S521). Thereby, the big hit game is started in accordance with the big winning opening / closing pattern set in the process of S519 or S520.

  Next, it is determined whether or not the probability variation flag is set to ON (S522). If it is determined that the probability variation flag is not set to ON (S522: NO), the process proceeds to S524, and the probability variation is determined. If it is determined that the flag is set to ON (S522: YES), the probability variation flag is set to OFF (S523). As a result, the probability variation function stops operating with the start of the big hit game.

  Next, it is determined whether or not the fluctuation shortening flag is set to ON (S524). As a result, when it is determined that the fluctuation shortening flag is not set to ON (S524: NO), the special symbol game process is terminated, and when it is determined that the fluctuation shortening flag is set to ON. (S524: YES), the fluctuation shortening flag is set to OFF (S525), and the release extension flag is set to OFF (S526). Thereby, with the start of the big hit game, the operation of the variable time shortening function and the open time extending function stops.

  On the other hand, when it is determined in the determination process of S517 that the winning symbol stopped on the first special symbol display unit 61 or the second special symbol display unit 62 is a small symbol (S517: YES), A small winning big opening opening / closing pattern is selected and set by random lottery using the second pattern selection table shown in FIG. 4B (S527), and the small hit game flag is set ON (S528). Thereby, the small hit game is started according to the big winning opening / closing pattern for small hits set in the process of S527.

  The small winning big winning opening / closing pattern set in the processing of S527 is the same as the second big winning big opening opening / closing pattern set in the processing of S520. For this reason, when the game per short opening (second probability variation big hit game, small hit game) occurs, the opening / closing operation of the big winning opening 33a is performed in a common (same) manner, so the operating mode of the big winning opening 33a Therefore, it is difficult to determine (obtain) which of the second probability variation big hit games or the small hit games is being executed among the short-open games.

  On the other hand, in the present embodiment, in the case of the second probability variation jackpot, the “selection rate of the opening / closing pattern whose execution timing of the final opening / closing operation of the large winning opening 33a is slow” is “the final opening / closing operation of the large winning opening 33a”. Is set higher than “selection rate of opening / closing pattern with early execution timing”, and in the case of small hit, “selection rate of opening / closing pattern with early execution timing of opening / closing operation of large winning opening 33a” is set to “large winning opening 33a” Is set higher than the “selection rate of the open / close pattern with a slow execution timing of the open / close operation”. Therefore, by paying attention to the execution timing (one or both of the opening start timing and the opening end (closing) timing) of the final opening / closing operation of the big winning opening 33a in the game per short opening, It can be inferred whether the “second positive variation big hit game” or the “small hit game” is being executed.

  Next, it is determined whether or not the fluctuation shortening flag is ON (S529). As a result, if it is determined that the variation shortening flag is not ON (S529: NO), the special symbol game process is terminated, and if it is determined that the variation shortening flag is ON (S529: NO), the variation shortening is performed. The counter is decremented by “1” (S530), and it is determined whether or not the fluctuation shortening counter has become “zero” (S531). If it is determined that the fluctuation shortening counter is not “zero” (S531: NO), the special symbol game process is terminated, and if it is determined that the fluctuation shortening counter is “zero” (S531: YES). ), The fluctuation shortening flag is set to OFF (S525), and the open extension flag is set to OFF (S526). As a result, the fluctuation time shortening function and the open time extending function stop operating.

  Next, in the determination process of S515, it is determined that the stop symbol of the special symbol stopped and displayed on the first special symbol display unit 61 or the second special symbol display unit 62 is not a winning symbol (big hit symbol or small hit symbol). If it is detected (in the case of a missing symbol) (S515: NO), it is determined whether or not the fluctuation shortening flag is ON (S532). As a result, if it is determined that the fluctuation shortening flag is not ON (S532: NO), the special symbol game process is terminated. On the other hand, when it is determined that the fluctuation shortening flag is ON (S532: YES), “1” is subtracted from the fluctuation shortening counter (S533). The fluctuation shortening counter is for monitoring the operation period of the fluctuation time shortening function and the opening time extension function, and at the end of the winning game, the type of winning symbol (winning game) The predetermined set value is set in the processing of S610g and S610l described later (see FIG. 11) in accordance with the gaming state at the time of occurrence of the game.

  Then, it is determined whether or not the fluctuation shortening counter obtained by subtracting “1” in S533 is “zero” (S534). As a result, when it is determined that the fluctuation shortening counter is not “zero” (S534: NO), the special symbol game process is terminated, and when it is determined that the fluctuation shortening counter is “zero” (S534). : YES), the fluctuation shortening flag is set to OFF (S535), and the release extension flag is set to OFF (S536).

  As a result, the fluctuation time shortening function and the open time extending function stop operating. Then, a mode designation command indicating a fluctuation mode (high probability normal fluctuation mode or low probability normal fluctuation mode) in which the fluctuation time shortening function and the open time extension function are not activated is transmitted to the sub-control unit 260 (S537). Upon receiving this mode designation command, the sub-control unit 260 displays characters, characters, backgrounds, and the like indicating that the variable time shortening function and the open time extending function are inactive (normal state). Process to be displayed.

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

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

  If it is determined in the determination process of S602 that the special winning opening 33a is not open (S602: NO), it is determined whether or not a winning game end condition is satisfied (S606). In the determination process of S606, if the game is the first jackpot game or the second jackpot game, whether or not the number of rounds of the jackpot game has reached “15 rounds” which is the maximum number of continuous rounds, It is determined whether or not the opening / closing frequency of the mouth 33a has reached “15”. Then, when “the number of rounds is 15 rounds” or “the number of times of opening and closing is 15”, it is determined that the winning game end condition is satisfied.

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

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

  In the winning game end process, first, the winning game flag (big hit game flag or small hit game flag) is set to OFF (S609a). Next, it is determined whether or not the hit (current hit) that triggered the end of the hit game is a probability change big hit (first probability change big hit or second probability change big hit) (S609b). The determination process of S609b is performed based on the “winning type” stored in the process of S516.

  As a result, when it is determined that the current hit is a probable big hit (S609b: YES), the probable change flag is set to ON (S609c). As a result, the probability variation function starts operation (becomes a high probability state).

  Next, it is determined whether or not the current hit is accompanied by the operation of the open time extension function (S609d). In the processing of S609d, when the current hit is “first positive variation big hit” or “second positive change big hit that occurred when the open time extension function is activated”, the open time extension function is activated. If it is determined that there is a hit and the current hit is “second positive variation big hit that occurred when the opening time extension function is not activated”, it is determined that the opening time extension function is not activated. The determination process of S609d is performed based on the “winning type” and “the setting state of the game state flag when the hit occurs” stored in the process of S516.

  If it is determined that the opening time extension function is not activated (S609d: NO), the winning game process is terminated, and if it is determined that the opening time extension function is operated (S609d: YES). ), The fluctuation shortening flag and the release extension flag are set to ON (S609e, S609f), and the fluctuation shortening counter is set to 10,000 times (S609g). As a result, the variable time shortening function and the open time extending function start to operate.

  On the other hand, when it is determined in the determination process of S609b that the current hit is not a probable big hit (S609b: NO), it is determined whether or not the current hit is a normal big hit (S609h). As a result, when it is determined that it is not a normal big hit (that is, when the current hit is a small hit) (S609h: NO), the hit game process is terminated, and when it is determined that the normal big hit is ( S609h: YES), the fluctuation shortening flag and the release extension flag are set to ON (S609j, S609k), and the fluctuation shortening counter is set to 100 times (S609l). As a result, the variable time shortening function and the open time extending function start to operate.

  Here, the correspondence between the processing shown in the flowcharts of FIGS. 7 to 11 and each means of the present invention will be described. The processing of S601 to S608 (FIG. 10) corresponds to the winning game execution means, “Processing in S508b and S509b (FIG. 9)” corresponds to the lottery means, “Processing in S609c (FIG. 11)” corresponds to the probability setting means, and “Processing in S519, S520, and S527 (FIG. 7B)”. "Corresponds to the execution pattern selection means.

  In the present embodiment described above, a plurality of winning opening opening / closing patterns A to D (see FIG. 3) having different execution timings of the final opening / closing operation of the winning opening 33a are provided, and each winning opening opening / closing pattern A to A plurality of pattern selection tables (see FIG. 4) having different selection rates of D are provided according to the type of game per second game (second probability variable big hit game or small hit game). Then, when starting a game per short opening, a special winning opening opening / closing pattern is selected using a pattern selection table corresponding to the game per short opening. As a result, the execution timing of the final opening / closing operation of the big winning opening 33a differs depending on the type of game per short opening, so the player pays attention to the opening / closing operation of the large winning opening 33a during the game per short opening. By doing so, it is possible to estimate the operating state of the probability variation function after the game per short opening based on the opening / closing operation (one or both of the final opening start timing and the opening end timing) of the big winning opening 33a. Gameability can be realized.

  In the present embodiment, since the first opening start timing of the big winning opening 33a is set at the same time in each of the big winning opening / closing patterns A to D, the "first opening start timing of the big winning opening 33a" and "the big winning opening" “Execution timing of final opening / closing operation of mouth 33a” has no correspondence, and “Execution timing of final opening / closing operation of special winning opening 33a” is predicted based on “First opening start timing of special winning opening 33a” I can't do it. For this reason, it is difficult for the player to recognize whether the execution timing of the final opening / closing operation of the big winning opening 33a is early or late until the final opening / closing operation of the big winning opening 33a is performed. Until the final opening / closing operation is performed, the player's expectation for the operation of the probability variation function can be maintained. Accordingly, it is possible to effectively provide a game property that the type of game per short opening, that is, the operation state of the probability variation function after the end of the game per short opening can be estimated based on the execution timing of the final opening / closing operation of the special winning opening 33a. Can be realized.

  Further, in this embodiment, during the execution of the game per short opening, it is configured to execute a mode transition effect in which the effect content changes according to the progress of the game per short opening, so the effect content of the mode transition effect It is possible to recognize at which stage the game per short opening is currently based on (progress progress). For this reason, it is easy for the player to recognize at which stage of the game per short opening the opening / closing operation of the final winning opening 33a is performed by focusing on the opening / closing operation of the large winning opening 33a and the mode transition effect. Become. Thus, it is possible to effectively play the game of estimating the operating state of the probability variation function based on the opening / closing operation (one or both of the opening start timing and the opening end timing of the final round) in the game per short opening. Can be realized.

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

  In the second embodiment, a second normal big hit game is set as a big hit game, in addition to the first positive probability big hit game, the first normal big hit game, and the second normal variable big hit game. The second normal big hit game constitutes a short open hit game together with the second probability variable big hit game and the small hit game. In the second normal jackpot game, a “second jackpot game” in which the opening time of the big winning opening 33a is set to a short time is implemented, and after the jackpot game is finished, any of the variable time shortening function, the open time extending function, and the probability varying function The function does not work. In this embodiment, the small hit game and the second normal big hit game correspond to the “second short-open game” of the present invention.

  FIG. 12 is a large winning opening / closing pattern selection table for games per short opening according to the second embodiment, and FIG. 12 (a) is a first chart for selecting a large winning opening / closing pattern for large winnings in the second probability variation big winning game. The pattern selection table (b) is a second pattern selection table for selecting a big winning opening / closing pattern in the small hit game and the second normal big hit game. In other words, in the second embodiment, the same second pattern selection table is used for the small hit game and the second normal big hit game. The selection rate of each pattern selection table is the same as that in the first embodiment.

  FIG. 13 is a flowchart showing the latter half of the special symbol game process of the second embodiment, and corresponds to FIG. 7B of the first embodiment. As shown in FIG. 13, when it is determined in the determination process of S518 that the winning symbol stopped on the first special symbol display unit 61 or the second special symbol display unit 62 is the second big symbol symbol ( S518: YES), it is determined whether or not the second big hit symbol is a probability variation big hit symbol (S538).

  As a result, if it is determined that the second big hit symbol is a probability variation big hit symbol (second positive variation big hit symbol) (S538: YES), the first pattern selection table shown in FIG. 12A is used. A large winning opening / closing pattern for the second probability variation jackpot is selected and set by random lottery (S520). On the other hand, when it is determined that the second big hit symbol is not the probability variation big hit symbol (S538: NO), the second big hit symbol is the second normal big hit symbol, so the second pattern shown in FIG. A second winning jackpot opening / closing pattern is selected and set by random number lottery using the selection table (S539).

  If it is determined in the determination process of S517 in FIG. 13 that the winning symbol stopped and displayed on the first special symbol display unit 61 or the second special symbol display unit 62 is a small hit symbol (S517: YES) ), A small winning big opening opening / closing pattern is selected and set by random lottery using the second pattern selection table shown in FIG. 12B (S527).

  FIG. 14 is a flowchart of the process at the end of the hit game in the second embodiment, and corresponds to FIG. 11 in the first embodiment. As shown in FIG. 14, in the second embodiment, when it is determined in the determination processing of S609h that the current hit is a normal big hit (S609h: YES), the normal big hit is an open time extension function. It is determined whether or not the operation is accompanied (S609i). In the processing of S609i, when the normal big hit that is the current hit is the “first normal big hit game” (when the finished normal big hit game is the “first normal big hit game”), the operation of the open time extension function is performed. If the normal big hit that is the current hit is “second normal big hit” (when the finished normal big hit game is “second normal big hit game”), the opening time extension function is It is determined that the operation is not performed. If it is determined that the opening time extension function is not activated (S609i: NO), the winning game process is terminated, and if it is determined that the opening time extension function is operated (S609i: YES). ), The fluctuation shortening flag and the release extension flag are set to ON (S609j, S609k), and the fluctuation shortening counter is set to 100 times (S609l).

  In the second embodiment described above, the same pattern selection table is used for the “small hit game” and the “second normal big hit game” as the second short-open game (see FIG. 12B). ). As a result, even in the configuration in which the second normal big hit game is provided, the player pays attention to the opening / closing operation of the big winning opening 33a during the execution of the short open hit game, as in the first embodiment. Realize a novel gameability in which the operation state of the probability varying function after the game per opening can be inferred based on the opening / closing operation (one or both of the final opening start timing and the opening end timing) of the special winning opening 33a. be able to.

(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to FIG. The third embodiment is different from the second embodiment in that different pattern selection tables are used for the small hit game and the second normal big hit game. In the third embodiment, the “small hit game” in the second short opening game corresponds to the “probability maintaining short release game” of the present invention, and the “second normal game” in the second short opening game. The “big hit game” corresponds to the “normal probability short-open game” of the present invention. Only the parts different from the second embodiment will be described below.

  As described above, after the end of the small hit game, the game state at the start of the small hit game (the operating state of the fluctuation time shortening function, the open time extension function, the probability fluctuation function) is maintained, whereas the second normal After the big hit game is over, none of the fluctuation time shortening function, the opening time extension function, and the probability fluctuation function is activated.

  For this reason, when a small hit occurs when only the probability variation function is activated and a small hit game is started, the gaming state at the start (variation time shortening function, opening time extension function, probability variation Since the function operating state) is maintained even after the small hit game ends, only the probability variation function is activated even after the small hit game ends. On the other hand, when the second normal big hit occurs when the fluctuation time shortening function and the open time extension function are not activated, the second big hit game is performed regardless of whether the probability fluctuation function is activated at the time of occurrence. After the end of the process, the probability variation function does not operate, and the variation time shortening function and the open time extension function do not operate. Because of the operation state of the probability variation function after the end of the hit game, the small hit game becomes a win game that is more advantageous to the player than the second normal big hit game.

  FIG. 15 is a large winning opening / closing pattern selection table for games per short opening according to the third embodiment, and FIG. 15 (a) is used to select a large winning opening / closing pattern for second certain variation big hits used in the second certain variation big winning game. (B) is a second pattern selection table for selecting a small winning big opening opening / closing pattern used in the small hit game, and (c) is a second pattern selection table used in the second normal big hit game. 2 is a third pattern selection table for selecting a big winning opening opening / closing pattern for a normal big hit. That is, in the third embodiment, different pattern selection tables are used for the small hit game and the second normal big hit game, and this point is different from the second embodiment. The selection rate of the first pattern selection table shown in FIG. 15A is the same as that of the first pattern selection table in each of the above embodiments, and the selection rate of the third pattern selection table shown in FIG. This is the same as the second pattern selection table of each embodiment.

  As shown in FIG. 15 (b), the second pattern selection table used when a small hit occurs has a 45% probability of selecting the special prize opening / closing pattern A, and the special prize opening / closing pattern B is selected. The probability that the winning opening / closing pattern C is selected is 18%, and the probability that the winning opening / closing pattern D is selected is 10%. In other words, in the third embodiment, in the second pattern selection table and the third pattern selection table, the selection rate of the big winning opening / closing pattern A whose execution timing of the final opening / closing operation of the big winning opening 33a is early is the big winning. The final opening / closing operation timing of the mouth 33a is set higher than the selection rate of the large winning opening / closing pattern D. In the third pattern selection table, the selection rate of the big winning opening / closing pattern A is set to be higher than the second pattern selection table because the final opening / closing operation of the big winning opening 33a is executed earlier.

  Next, the opening / closing pattern setting process for the special winning opening 33a performed in the special symbol game process of the third embodiment will be described. The second half of the special symbol game process of the third embodiment is performed based on the flowchart shown in FIG. 13 as in the second embodiment. First, in the process of S520, a second winning big opening winning opening / closing pattern for probability variation is selected and set by random number lottery using the first pattern selection table shown in FIG. In the process of S539, the second normal big hit big opening / closing pattern is selected and set by random number lottery using the third pattern selection table shown in FIG. In the process of S527, the big winning opening / closing pattern for small hits is selected and set by random lottery using the second pattern selection table shown in FIG.

  As described above, in the third embodiment, when the second probability variation big hit game is executed, the big winning opening / closing pattern with the slow execution timing of the final opening / closing operation of the big winning opening 33a is the big winning opening. Based on the “first pattern selection table (first selection condition)” that is easier to select than the large winning opening opening / closing pattern whose execution timing of the final opening / closing operation 33a is earlier, the large winning opening opening / closing pattern is selected. In addition, when a small hit game is executed, the large winning opening / closing pattern with the early execution timing of the final opening / closing operation of the big winning opening 33a is late in the execution timing of the final opening / closing operation of the large winning opening 33a. Based on the “second pattern selection table (second selection condition)” that is easier to select than the big winning opening / closing pattern, the big winning opening / closing pattern is selected. When the second normal jackpot game is executed, the big winning opening opening / closing pattern (big winning opening opening / closing patterns A and B) with the early execution timing of the final opening / closing operation of the big winning opening 33a is “the second pattern”. Based on the “third pattern selection table (third selection condition)” that is easier to select than the “selection table”, the special winning opening opening / closing pattern is selected.

  In the configuration of the third embodiment described above, the “small hit game (game per probability maintaining short release)” and the “second normal big hit game (game per normal probability short release)”, which are games per second short opening, Different pattern selection tables are used (see FIGS. 15B and 15C). Therefore, based on the execution timing of the final opening / closing operation of the big winning opening 33a during the execution of the short opening per game, the small hit game and the second normal big hit game can be distinguished and estimated. Thus, even when the small hit game or the second normal big hit game is started while the probability variation function is in operation (probability changing game state), the player pays attention to the opening operation of the big winning opening 33a during the hit game. Thus, a novel game in which the operating state of the probability variation function after the game per short opening can be estimated based on the opening / closing operation (one or both of the final opening start timing and the opening end timing) of the special winning opening 33a. Can be realized.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described with reference to FIG. In the fourth embodiment, the opening / closing patterns of the special winning openings 33a are different from those of the above embodiments. Only the parts different from the above embodiments will be described below.

  FIG. 16 is a timing chart showing the opening / closing patterns of the big winning opening 33a (second big winning big opening opening / closing pattern and small winning big opening opening / closing pattern) in the short opening game of the fourth embodiment. This corresponds to FIG. 3 of the first embodiment.

  The plurality of large winning opening / closing patterns A to D of the present embodiment are “the first opening (first time) opening timing of the large winning opening 33a” and “the opening start timing of the last time (15th) of the large winning opening 33a”. Are different from each other, and “the order of the opening timing of the first winning opening 33a” and “the order of execution timing of the last opening / closing operation of the winning prize opening 33a” in the respective opening / closing patterns A to D are opposite to each other. It has become. Specifically, the first winning opening timing of the special winning opening 33a is the slowest in the special winning opening / closing pattern A, followed by the special winning opening / closing pattern B, the special winning opening / closing pattern C, and the special winning opening / closing pattern D in this order. The winning opening / closing timing A is the earliest opening start timing and opening end timing of the winning opening 33a, and the winning opening opening / closing pattern B, the winning opening opening / closing pattern C, and the opening / closing of the winning opening are performed. It is slower in the order of pattern D.

  In the present embodiment, the opening times of the big prize opening 33a in each of the big prize opening / closing patterns A to D are the same, and the closing times (interval times) of the big prize opening 33a are different. Specifically, the total closing time (total closing time) of the special winning opening 33a from the start to the end of the game per short opening is the shortest winning opening opening / closing pattern A, the big winning opening opening / closing pattern B, and the big winning prize. The opening / closing pattern C and the special winning opening / closing pattern D are longer in this order. Thereby, the execution timings of the first and final opening / closing operations of the special winning opening 33a in the special winning opening / closing patterns A to D are made different.

  In the configuration of the fourth embodiment described above, the “first winning opening timing of the big winning opening 33a” and the “execution timing of the final opening / closing operation of the big winning opening 33a” are not related, and the “big winning opening 33a It is difficult to estimate "the final opening start timing of the big winning opening 33a" and "the final opening end timing of the big winning opening 33a" based on "the first opening start timing of". For this reason, it is difficult for the player to recognize whether the execution timing of the final opening / closing operation of the big winning opening 33a is early or late until the final opening / closing operation of the big winning opening 33a is performed. It is possible to maintain the player's expectation for the operation of the probability variation function until the final opening / closing operation is executed. As a result, the operation state of the probability variation function after the game per short opening is ended is changed to the execution timing of the final opening / closing operation of the big winning opening 33a in the game per short opening (the final opening start timing and the opening end timing). It is possible to effectively realize a gameability that can be estimated based on one or both of them.

  Also, generally, in the large winning opening / closing pattern in which the first opening opening timing of the big winning opening 33a is early, the execution timing of the final opening / closing operation of the large winning opening 33a is earlier, and the first opening of the large winning opening 33a is started. It is considered that the player recognizes that the timing for performing the final opening / closing operation of the special winning opening 33a is delayed in the case of the special winning opening / closing pattern with a slow timing. On the other hand, in this embodiment, in each of the prize winning opening / closing patterns A to D, the order of the first opening start timing of the prize winning opening 33a and the order of the execution timing of the final opening / closing operation of the prize winning opening 33a are as follows. Is reversed. For this reason, it is possible to provide unexpectedness in the relationship between “the first opening start timing of the big winning opening 33a” and “the execution timing of the final opening / closing operation of the big winning opening 33a” in the game per short opening. As a result, the type of game per short opening, that is, the game per short opening ends, based on the execution timing (one or both of the final opening start timing and opening end timing) of the final opening / closing operation of the special winning opening 33a. Thus, it is possible to more effectively realize the gameability in which the operation state of the probability variation function can be estimated.

(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 above-described embodiments, it has been described that the selection of the big winning opening / closing pattern is performed by random lottery. However, the selection of the big winning opening / closing pattern is selected according to the type of the winning symbol (second probability variable big winning symbol or small winning symbol). May be performed based on That is, a random number lottery (lottery using a special symbol determining random number) for determining the second probability variation big hit symbol or the small hit symbol can be applied to the random lottery for selecting the big winning opening / closing pattern. For example, in the configuration of the first embodiment, the second probability variation big hit symbol A to D and the small hit symbol A to D corresponding to the big winning opening and closing patterns A to D are set, and each second probability variation big hit symbol A to D is set. The selection rate of the first symbol lottery table corresponding to the selection rates of the big winning opening and closing patterns A to D in the first pattern selection table (see FIG. 4A) and the selection rates of the small winning symbols A to D Prepares a second symbol lottery table corresponding to the selection rate of each large winning opening / closing pattern A to D in the second pattern selection table (see FIG. 4B). Then, by performing random number lottery using these lottery tables, selection of a specific winning symbol (second positive variation big winning symbol or small winning symbol) and a winning prize corresponding to the selected winning symbol AD The open / close patterns A to D can be selected.

  In addition, since the combination of lighting and extinction of the plurality of LEDs constituting the special symbol display units 61 and 62 can be set in various ways, for the player, the special symbol display unit when the second probability variation big hit or small hit occurs. It becomes difficult to determine whether the special symbol stopped and displayed at 61, 62 is the “second positive variation big hit symbol” or the “small hit symbol”. Therefore, even if the big winning opening opening / closing pattern is selected by random number lottery (the lottery using a special symbol decision random number) for determining the second probability variation big hit symbol or the small hit symbol, the player will receive the “first win” Since it is difficult to accurately determine whether it is “two-probable big hit” or “small hit”, it is possible to achieve the same game play as in the above embodiments.

  In the first embodiment, only the small hit game is provided as the second short open game, and in the second and third embodiments, the small hit game and the second normal big hit game are used as the second short open game. Although the structure provided is demonstrated, this invention is applicable not only to this but to the structure which provides only a 2nd normal big hit game as a game per 2nd short opening.

  Further, in each of the above-described embodiments, the final winning opening 33a is opened in each of the large winning opening / closing patterns A to D by changing the closing time of the large winning opening 33a of each of the large winning opening / closing patterns A to D. The start timing and the opening end timing (closing timing) are configured to be different. However, the present invention is not limited to this, and it is possible to change the opening times of the large winning openings 33a of the large winning opening / closing patterns A to D, thereby different winnings. The final opening start timing and the opening end timing of the special winning opening 33a in the mouth opening / closing patterns A to D may be varied. Alternatively, the opening of the final winning opening 33a in each of the winning opening opening / closing patterns A to D is started by changing both the opening time and closing time of the winning opening 33a of each winning opening opening / closing pattern A to D. The timing and the opening end timing may be different.

  Also, by changing the opening time and closing time of the grand prize opening 33a according to each opening / closing pattern, only the “last opening start timing of the big prize opening 33a” is made different. Only the “opening end timing” can be changed. Even in such a case, the game ends per short opening based on the execution timing (one or both of the opening start timing and the opening end timing of the final opening) of the final winning opening 33a in the game per short opening. It is possible to realize the gameability that the operation state of the later probability variation function can be estimated.

Claims (1)

A game per long opening that opens a large winning opening multiple times based on a long opening time that makes it easy to enter a game ball and a large winning opening that opens multiple times based on a short opening time that makes it difficult to enter a game ball Per game execution means capable of executing a game per short opening;
Lottery means for performing a lottery on whether or not to execute the winning game;
A probability setting means for setting the winning probability of the lottery to a normal probability or a high probability higher than the normal probability,
A game per first short opening and a game per second short opening are set as the games per short opening,
The probability setting means includes:
When the game per first short opening is executed, the winning probability of the lottery performed after the game per first short opening ends is set to a high probability, and the game per second short opening is executed. And a gaming machine that sets the winning probability of the lottery performed after the second short opening game ends to the same probability or the normal probability as before the start of the second short opening game,
Execution pattern storage means for storing a plurality of execution patterns having different execution timings of the final opening / closing operation among the plurality of times as an execution pattern of the opening / closing operation of the big prize opening in the game per short opening;
When executing the game per short opening, the execution pattern of the opening / closing operation of the big prize opening used in the game per short opening is selected from a plurality of execution patterns stored in the execution pattern storage means according to a predetermined selection condition Execution pattern selection means to perform,
As the selection condition, a first selection condition in which a selection rate of an execution pattern having a late execution timing of the final opening / closing operation is set higher than a selection rate of an execution pattern having an early execution timing of the final opening / closing operation, and A selection condition storage means for storing a second selection condition in which a selection rate of an execution pattern having an early execution timing of the final opening / closing operation is set higher than an selection pattern of an execution pattern having a late execution timing of the final opening / closing operation; ,
Production executing means for performing a predetermined short opening game effect during execution of the short opening game,
With
When the game per short opening to be executed is the game per first short opening, the execution pattern selecting means selects the execution pattern of the opening / closing operation of the big prize opening used in the game per first short opening. When the game per short opening that is selected and executed based on the first selection condition is the game per second short opening, execution of the opening / closing operation of the big prize opening used in the game per second short opening Selecting a pattern based on the second selection condition ;
The game effect per short opening is configured such that the content changes according to the progress of the effect,
Furthermore, the game effect per short opening starts before the game per short opening and ends after the game per short opening, and is thereby defined by each of the plurality of execution patterns. The timing of execution of the final opening / closing operation is set from the start to the end of the game effect per short opening and is different from each other .
