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).

  The pachinko machine is configured to perform a big hit lottery when a game ball enters the start opening, and if the lottery result is a big hit, the big hit lottery game will be executed after the big hit game ends. There are many things that execute probability change games. Since the probability variation game started after the end of the big hit game is maintained until the next big hit game is generated, a so-called continuous change state occurs in which the next big hit game is continuously generated after the big hit game is once ended.

  In such a pachinko machine, a two-stage lottery is performed for the purpose of suppressing gambling, and the second-stage lottery is performed only when the first-stage lottery is won, and the second-stage lottery is won. In such a case, a gaming machine that starts a big hit game has been proposed (see Patent Document 1).

JP 2003-265777 A

  However, in the configuration of Patent Document 1, the second stage lottery, which is a big hit lottery, is not performed unless the first stage lottery is passed. Even after the big hit game is over, the big hit lottery is not carried out unless the first lottery is passed again. In other words, if two lotteries of the first stage and the second stage are not passed, the big hit game cannot be generated again, and the big hit game starts again after the big hit game is finished once, so-called big hit pullback is performed. Is difficult. For this reason, it is difficult to create an opportunity that is advantageous to the player, and there is a problem that the game is not attractive.

  Therefore, in view of the above points, the present invention aims to create an advantageous opportunity for a player in a gaming machine that starts a big hit game through a two-stage lottery.

In order to achieve the above object, the present invention provides:
A first start gate capable of entering a game ball flowing down the left area on the game board surface;
A second start gate capable of entering a game ball flowing down the right area on the game board surface;
The game ball can be switched between a closed state in which the game ball cannot enter and an open state in which the game ball can enter, and when the game ball is in the open state, the game ball flowing down the right region on the game board surface can enter The starting port,
The game ball can be switched between a closed state in which the game ball cannot enter and an open state in which the game ball can enter, and when the game ball is in the open state, the game ball flowing down the right region on the game board surface can enter With a big prize opening,
When the game ball passes through the first start gate or the second start gate, a normal symbol game is performed in which the normal symbol is variably displayed on the normal symbol display device, and the normal symbol display device is obtained as a result of the normal symbol game. When the normal symbol is stopped and displayed, the special symbol display device uses the special symbol display device when the starting port in the closed state is opened and a game ball enters the starting port in the open state. A special symbol game is displayed in which the special symbol game is variably displayed, and when the special symbol is stopped and displayed on the special symbol display device as a result of the special symbol game, the big winning game in which the closed prize winning opening is opened is executed. In the gaming machine
A first game progression means for advancing a first game consisting of the normal symbol game in which the probability that the winning normal symbol is stopped and displayed on the normal symbol display device is set to a first probability;
In the first game, when a game ball enters the start port that is opened when the winning normal symbol is stopped and displayed, the probability that the winning special symbol is stopped and displayed is higher than the first probability . A second game progression means for advancing a second game consisting of the special symbol game set to two probabilities;
When a game ball enters the start port during execution of the special symbol game, the special symbol game corresponding to the ball is stored as a hold to be executed after the special symbol game being executed is completed. Storage means;
In the second game, the winning special symbol is stopped and displayed, and when the big hit game accompanying the stop display of the corresponding special symbol is finished, the probability that the winning normal symbol is stopped and displayed is higher than the first probability. A high probability game consisting of the special symbol game set to a probability and the special symbol game set to a fourth probability that is higher than the second probability is the probability that the winning special symbol is stopped and displayed. High-probability game progression means to advance until is established,
After the end of the high-probability game, the probability that the winning symbol is stopped and displayed is set as the third probability, and the probability that the winning special symbol is stopped and displayed is set as the second probability. Special game progression means for advancing special games consisting of special symbol games;
With
The special game has at least A when the upper limit of the number of executions of the special symbol game is A and the second probability that the special symbol is stopped and displayed in one special symbol game is 1 / B. Satisfying ≧ 3 × B,
The high-probability game end condition is that a special winning special symbol in the special winning symbol in the winning special symbol is set when the predetermined big winning game is executed and before the multiple winning game is executed. It is established when the jackpot game accompanying the stop display is executed,
The high probability game progression means advances the high probability game in a mode in which the stop display probability of the special special bonus symbol is different according to the number of executions of the large number of big hit games,
When the jackpot game accompanying the stop display of the special hit special symbol is executed and the high probability game ends, the special game progress means then advances the special game,
When the high-probability game is terminated without executing the jackpot game associated with the stop display of the special hit special symbol, the second number of times corresponding to the number of the suspensions stored in the suspension storage means is thereafter performed. The game progression means advances the second game,
When the special symbol is stopped and displayed during the special game and the second game, until the high-probability game end condition is newly established from the end of the jackpot game associated with the special special symbol stop display. The high-probability game advancing means advances the high-probability game.

According to the configuration of the present invention , while the “high probability game” is being performed, the first stage lottery (ordinary symbol game) and the second stage lottery (special symbol game) are won with high probability. It is possible to reliably generate a state in which the big hit game continues (so-called continuous change).

Then, when the high-probability game is completed through the stop display of the special symbols per special, because the probability of stopped and displayed in the symbol per the normal symbol in the "special game" performed thereafter it becomes a high probability, easily two It is possible to shift to the special symbol game which is the lottery at the stage, and it is easy to generate a big hit again (easy to pull back the big hit). Also, if the high-probability game is ended without Rukoto via special stop display per special, if pending (game balls ball entrance information to start hole) is stored, via the normal symbol game of the first stage Without this, the second stage “special symbol game (second game)” can be executed. For this reason, even if the high probability game is terminated without displaying the special hit special symbol stop display, it is easy to generate a big hit again after the big hit game ends (easily pull back the big hit). As described above, in the present invention, in a gaming machine adopting a two-stage lottery that allows a special symbol game (second-stage lottery) to be executed only through a normal symbol game (first-stage lottery), After the probabilistic game is once finished, it is possible to provide gameability that is likely to generate a big hit again (easy to pull back the big hit), and it is possible to effectively create an opportunity for a player advantage. Also, once the high-probability game has ended, depending on the end mode ( whether or not the special hit special symbol is stopped and displayed), the big hit game and the state in which the big hit game continues (so-called continuous change) are generated again Since the game process until the game is made different can be realized, it is possible to realize a new game property that pays attention to the end mode of the high probability game. As a result, the game interest of the player can be effectively enhanced.

In addition, the gaming machine of the present invention is configured such that the stop display probability of the special hit special symbol in the high probability game is increased step by step as the last big hit game of the plurality of big hit games is approached. It is characterized by being. Thus, stopping the display probability per special special symbols as the number of executions of the jackpot gaming at high probability game is increased higher due. As a result, as the end time of high-probability games approaches, the possibility of the occurrence of later special games increases , making it easy to generate another big hit (easy to pull back the big hit), creating an opportunity for the player's advantage can do.

  According to the configuration of the present invention described above, in a gaming machine that starts a big hit game through a two-stage lottery, after the big hit game is once ended, it is easy to generate a big hit again (easily pull back the big hit) It is possible to create an advantageous opportunity for the player.

The game board 20 is a substantially rectangular wooden plate-like body and is detachably attached to the middle frame 3, and its back side is covered by a back mechanism board (not shown).

As shown in FIG. 2, a substantially circular game area 21 is formed on the game board 20 by an outer rail 22 and an inner rail 23 provided on the surface (board surface) of the game board 20. In the game area 21, there are a central device 24, normal symbol operation gates 26 and 27, a normal symbol display unit 28, a starting port 30 (ordinary electric accessory), a special symbol display unit 31, and a prize winning device (special electric accessory). 33, game devices such as winning holes 34 to 38 are arranged. In addition, a number of obstacle nails are arranged in the game area 21 in consideration of the position balance with each gaming device. In addition, in the gaming machine 1 of the present embodiment, there is no start port for operating the special symbol other than the start port 30. That is, unless the normal symbol lottery is won, the special symbol lottery does not start. Therefore, it can be said that the normal symbol lottery is the first stage lottery, and the special symbol lottery is the second stage lottery.

  The central device (center accessory) 24 is disposed at a substantially central portion of the game area 21 and includes an effect display device 25. In the present embodiment, a display device using a dot matrix is used as the effect display device 25, and various effect displays are performed in the display area of the effect display device 25.

  In this embodiment, two normal symbol operation gates 26 and 27 are provided. The first normal symbol operating gate 26 is provided below the central device 24, and the second normal symbol operating gate 27 is provided at the upper right of the central device 24. Inside the normal symbol operating gates 26 and 27, normal symbol operating gate detection switches 26s and 27s (see FIG. 3) for detecting the passage of the game ball are provided. When the game ball passes through the normal symbol operation gates 26 and 27, the normal symbol starts to display a change.

  The normal symbol display unit 28 is provided at the lower right of the central device 24. The normal symbol display unit 28 is composed of one LED, and the normal symbol is displayed by this LED. The normal symbol display unit 28 performs normal symbol variation display and stop display. When the game ball passes through the normal symbol operation gates 26 and 27, the normal symbol starts to change in the normal symbol display unit 28, and after a predetermined time has passed, the normal symbol hits in the normal symbol display mode or the off-normal symbol display mode. A normal symbol game that is stopped and displayed is performed.

  In this embodiment, there is provided a normal symbol success / failure random number which is acquired when a game ball passes through the normal symbol operation gates 26 and 27 and is used for normal symbol success / failure determination of whether or not to activate the start port 30. . As the normal symbol operation gates 26 and 27 pass through the game ball, a normal symbol success / failure random number is acquired, and the acquired normal symbol success / failure determination random number is stored in a predetermined area of the RAM of the main control unit 200. .

  Here, normal symbol holding will be described. The usual hold display unit 29 is composed of 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.

  The number of game balls that have passed through the normal symbol operation gates 26 and 27 can be held up to the maximum number of reservations (four in this embodiment) as the number of normal symbol reservations. The number of normal symbol holdings is the number of random numbers for determining whether or not the normal symbol is determined and stored in a predetermined area of the RAM of the main control unit 200 every time a game ball passes to the normal symbol operating gates 26 and 27 (stored number). ). 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 normal symbol success / failure random numbers are set in advance, and the normal symbol success / failure random numbers acquired at the timing when the game ball passes the normal symbol operation gates 26 and 27 match the winning value. It is determined to be a hit. In this embodiment, the probability that the random number for determining whether or not the normal symbol matches the winning value (the winning probability of the normal symbol) is a low probability (1/135 in this embodiment). Note that the normal symbol game performed with the normal symbol winning probability (probability that the symbol is stopped and displayed on the normal symbol display unit 28) set to a low probability corresponds to the first game of the present invention.

  The probability of winning a normal symbol is improved to a high probability (1 / 1.01 in this embodiment) during a short time game (open time extension function is activated), which will be described later. If it is determined that the winning symbol is a winning symbol, the normal symbol that is stopped and displayed on the normal symbol display unit 28 is determined to be a winning normal symbol display mode. 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 that is stopped and displayed in the normal symbol display unit 28 is determined as the display mode of the out of normal symbol. Is done. The normal symbol success / failure determination, the normal symbol variation display and stop display, the normal symbol stop symbol determination, the normal symbol hold and hold reservation are performed by the main control unit 200 described later, and the main control unit 200 performs the present invention. Corresponds to the first game progression means.

  When the normal symbol is stopped and displayed in a preset normal symbol display mode, the start port 30 is opened. The start port 30 is provided on the right wall surface of the central device 24. The start port 30 is configured as a game ball receiving port that receives a game ball flowing down on the surface of the game board 20. The starting port 30 includes a blade part 30a, and the blade part 30a is a variable starting port that changes between a closed state along the wall surface and an open state in which the upper end rotates leftward about the lower end. It is configured as. Inside the start port 30, there are a start port entrance detection switch 30s (see FIG. 3) for detecting the entry of a game ball and a start port solenoid 30c (see FIG. 3) for operating the wing piece 30a. Is provided.

  When the wing piece 30a is opened, the starting port 30 is in a state where the possibility of entering a game ball is high, and when the wing piece 30a is closed, the game ball cannot enter. When the normal symbol is stopped and displayed as a combination of symbols, the wing piece 30a is opened to expand the game ball receiving port of the start port 30, and the start port 30 functions as a normal electric accessory. The open state of the start port 30 is ended when a predetermined end condition is established, and the open start port 30 is closed. As a predetermined end condition, when the opening time of the start port 30 reaches a predetermined time (5.8 seconds in this embodiment), or when a specified number (5 in this embodiment) of game balls enter. , Transition to the closed state. Since the starting port 30 is closed in a normal state, a game ball will not enter the starting port 30 unless a normal symbol game is won. The opening / closing control of the start port 30 is performed by the main control unit 200.

  The special symbol starts to fluctuate when the game ball enters the start port 30. The special symbol display part 31 is comprised from two LED, and a special symbol is displayed by these LED. Each LED constituting the special symbol display unit 31 can be turned on and off, and a plurality of display forms of the special symbol can be displayed by a combination of turning on and off of each LED. Of the combinations of special symbols displayed by two LEDs, a specific combination is set as a hit special symbol (big hit symbol), and other than the hit special symbol is set off as a special symbol (off symbol) Yes. In this embodiment, the special symbol variation display is performed by blinking display in which each LED is repeatedly turned on and off. In this embodiment, a plurality of jackpot symbols are set, and specifically, “probable variation jackpot symbol” and “normal jackpot symbol” are set as described later.

  When the game ball enters the start port 30, the special symbol starts to change in the special symbol display unit 31, and a special symbol game is performed in which the special symbol is stopped and displayed as a big hit symbol or a missed symbol after a predetermined time has elapsed. In this embodiment, the variation time of the special symbol is fixed to 20 seconds when the winning probability of the special symbol (the probability that the big hit symbol is stopped and displayed on the special symbol display unit 31) is low. Furthermore, a predetermined number of prize balls (for example, eight prize balls for one entry) are paid out in accordance with the entry of game balls into the start port 28. As will be described later, the variation time of the special symbol when the winning probability of the special symbol is high is fixed to 0.5 seconds.

  In this embodiment, a special symbol success / failure determination random number is provided that is acquired when a game ball enters the start port 30 and is used for determining whether or not to execute a jackpot game (special game). Yes. Furthermore, a special symbol determining random number for determining a stop symbol of the special symbol is provided. As the game ball enters the start port 30, a special symbol success / failure determination random number and a special symbol determination random number are acquired, and the acquired special symbol determination random number and special symbol determination random number are stored in the main control unit 200. Is stored in a predetermined area (holding storage area) of the RAM. The special symbol success / failure determination random number and the special symbol determination random number correspond to the special symbol variation information of the present invention.

  Here, the holding of special symbols will be described. The special symbol hold display unit 32 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.

The number of game balls that have entered the starting port 30 can be reserved until the maximum number of reservations (four in this embodiment) is reached as the number of special symbol reservations. The number of special symbol reservations is the number of random numbers for special symbol success / failure determination that is acquired every time a game ball enters the start port 30 and stored in a predetermined area (holding storage area) of the RAM of the main control unit 200. It corresponds to (memory number). In the present embodiment, the special symbol determination random number is acquired together with the special symbol determination random number as the game ball enters the start port 30. Therefore, the special symbol holding number is the number of stored special symbol determination random numbers. It corresponds to. The number of special symbol reservations is digested each time a special symbol success / failure determination is performed and the variation display of the special symbol is started, and decreases by one. Note that special symbol hold and hold digestion and special symbol success / failure determination are performed by the main control unit 200 described later, and the main control unit 200 corresponds to the hold storage unit and the special symbol lottery unit of the present invention.

  The special symbol success / failure random number is preset with a success / failure hit value. A big hit is determined when the special symbol success / failure random number acquired at the timing when the game ball enters the start port 30 matches the winning value set in the normal game success / failure determination table. In this embodiment, the probability that the special symbol success / failure random number matches the winning value (special symbol winning probability) is 1/10 at a low probability. As will be described later, the winning probability of special symbols is 1/1. The special symbol success / failure determination is performed when the special symbol starts the variable display. When the result of the special symbol success / failure determination is a big hit, the special symbol stopped and displayed on the special symbol display unit 31 is determined to be a big hit symbol (probability big hit symbol or normal big hit symbol). The type of jackpot symbol of the special symbol is determined based on a special symbol determining random number. On the other hand, when the special symbol winning / failing determination is out of place, the special symbol that is stopped and displayed by the special symbol display unit 31 is determined to be the out symbol. Note that the special symbol game performed in a state where the winning probability of the special symbol is set to a low probability corresponds to the second game of the present invention, and the main control unit 200 corresponds to the second game progression means of the present invention.

  The special symbol is configured to change and display according to a predetermined change pattern. This variation pattern defines the variation time of the special symbol and the presence / absence of the reach effect in the variation (effect content). The variation pattern of the special symbol is selected by lottery from a variation pattern table (variation pattern storage means) 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 selected according to the gaming state. The plurality of variation pattern tables include a hit variation pattern table selected when the success / failure determination result is a big hit, and a miss variation pattern table selected when the success / failure determination result is unacceptable.

  Next, the jackpot game (special game) will be described. When the special symbol stopped and displayed on the special symbol display unit 31 is a hit special symbol (when the result of the special symbol success / failure determination is a big hit), the main control unit 200 is a big hit game that is relatively advantageous to the player. Start (special game). The jackpot game is started by setting the jackpot game flag to ON.

  During the big hit game, the big prize device 33 (attacker) operates. The big winning device 33 is disposed below the start port 30 on the right side of the central device 24 in the game area 21. In the present embodiment, the big winning device 33 is disposed in the vicinity of the start port 30. The big prize device 33 includes a big prize opening 33a and a wing piece portion 33b for opening and closing the big prize opening 33a. The wing piece part 33b has a closed state along the wall surface and a lower end centering on the lower end, and the upper end is directed to the left. It is comprised so that it may change to the open state rotated. The big winning device 33 includes a big winning opening solenoid 33c (see FIG. 3) for operating the wing piece portion 33b and a big winning opening entrance detecting switch 33s (see FIG. 3) for detecting the entering of a game ball. Is provided.

  During the big hit game (during special game), the big prize device 33 is operated, and a predetermined number of prize balls (for example, 12 for one pitch) according to the number of game balls entered into the big prize opening 33a. Award balls). Specifically, when the big hit game is started, the big prize opening device 33 (special electric accessory) is continuously operated, and the big prize opening opening / closing operation for switching the big prize opening 33a between the open state and the closed state is continuously performed a plurality of times. Done.

  In other words, the big hit game gives the player a profit (prize ball) with respect to the entry of the game ball into the big prize opening 33a by opening and closing the big prize opening 33a a plurality of times, and the main control unit 200 This corresponds to the jackpot game execution means of the present invention. The big hit game is realized by repeatedly executing a special electric accessory game process described later.

  With the start of the operation of the special winning device 33, the special winning opening 33a is opened. This open state is ended when a predetermined end condition is established, and the open special winning opening 33a is closed. As a predetermined end condition, when the opening time of the big winning opening 33a reaches a predetermined time (5 seconds in this embodiment), or when the number of game balls that have entered the opened large winning opening 33a is a predetermined number (this embodiment) In the example, it is possible to reach 1).

  When it is assumed that one round is from the start to the end of the open state of the big winning opening 33a, the big hit game is ended by performing a predetermined number of rounds. In the grand prize winning device 33, after the opening of the big prize winning opening 33a is completed, that is, after a predetermined time (for example, 2 seconds) has passed since the big winning prize opening 33a is closed, the big winning prize opening 33a is again opened. Round begins. The opening / closing operation of the grand prize opening 33a in which one round is from the opening start to the end of the big prize opening 33a is repeated until a predetermined maximum number of continuous rounds (two rounds in this embodiment) is completed.

  In the gaming machine of this embodiment, after the big hit game is finished, the probability variation function starts to operate with a probability of 100%, and the special symbol probability changing game is started. The special symbol probability variation game is realized by the control of the main control unit 200. In this special symbol probability variation game, the variation time shortening function for shortening the variation time of the normal symbol and the special symbol, and the start port 30 The opening time extending function for extending the opening time and the probability variation function for changing (improving) the probability of the special symbol success / failure determination, that is, the probability that the special symbol is stopped and displayed as a jackpot symbol are activated. The variation time shortening function includes a normal symbol variation time shortening function for shortening the normal symbol variation time and a special symbol variation time shortening function for shortening the special symbol variation time.

  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 probability variation function, variation time shortening function, and opening time extension function constituting the probability game are the predetermined number of times (10000 in this example) until the next jackpot game is started after the jackpot game is finished or until the next jackpot game is started. Until it reaches).

  In the present embodiment, the normal symbol winning probability is improved as described above by the operation of the opening time extension function. In the present embodiment, the winning probability of the normal symbol is changed from a low probability (1/135 in the present embodiment) to a high probability (1 / 1.01 in the present embodiment) by the operation of the open time extension function. As the winning probability of the normal symbol increases, when the game ball passes through the normal symbol operation gates 26 and 27, the opening frequency of the start port 30 is improved, and the game ball entering frequency to the start port 30 is normal. It becomes higher than the time (when the open time extension function is not activated). Moreover, the fluctuation time of the normal symbol and the special symbol is shortened to 0.5 seconds by the operation of the fluctuation time shortening function.

  In addition, when the probability variation function is in operation, the probability of special symbol success / failure determination is improved by performing the success / failure determination using the probability variation game success / failure determination table in which the winning value for success / failure determination is increased from the normal game success / failure determination table. . In this embodiment, when the probability variation function is activated, the winning probability of the special symbol is improved from a low probability (1/10 in this embodiment) to a high probability (1 / 1.1 in this embodiment). As described above, the winning probability of the normal symbol is improved by the operation of the opening time extension function. For this reason, during a probability variation game, a high-probability game consisting of a normal symbol game with a high probability of winning a normal symbol and a special symbol game with a high probability of winning a special symbol will be played. The main control unit 200 corresponds to the high probability game progression means of the present invention.

  During the probability change game, the opening frequency of the start port 30 is improved and the probability of the special symbol success / failure determination is improved, so that after the big hit game is finished, the next big hit game is surely started.

  In the present embodiment, the probability that the result of the special symbol success / failure determination result is a probable big hit (the probability that the special symbol will stop display with the probable big hit symbol) becomes 100% up to a predetermined number of times (9 in this embodiment). ing. That is, the probability that the probability variation function starts operating after the big hit game ends is 100%, up to a predetermined number of times (9 in this embodiment). The tenth big hit usually stops at the big hit symbol. When the tenth big hit game ends, the winning probability of the special symbol returns to the normal low probability. In other words, if it is a big hit once, it will be a big hit with 10 sets.

  After the jackpot game is completed a predetermined number of times (10 in this embodiment), the probability of the special symbol success / failure determination becomes a normal low probability. In this case, a short-time game start lottery for determining whether or not to start a short-time game at the end of the big hit game is performed. In this example, a short-time game start lottery is performed based on the type of jackpot symbol that caused the start of the big hit game, and when the big hit symbol is a short-time big hit symbol, the short-time game start lottery is won, and the big hit symbol is normal In the case of a big hit symbol, the short-time game start lottery is missed. In this embodiment, the probability of winning the short-time game start lottery (probability of starting the short-time game) is set to 84%. By winning the short-time game start lottery, the short-time game starts after the big hit game ends, and the variable time reduction function and the open time extension function start to operate. The variable time reduction function and the open time extension function that make up the short-time game, after the jackpot game is finished, until the next jackpot game is started, or the number of fluctuations of the special symbol is a predetermined number of times (100 times in this example) Operates until it reaches.

  As described above, with the start of the short-time game, the winning probability of the special symbol becomes low, and the winning probability of the normal symbol remains high. For this reason, during a short-time game, a special game consisting of a normal symbol game with a high probability of winning a normal symbol and a special symbol game with a low probability of winning a special symbol will be played. The main control unit 200 corresponds to the special game start determining unit and the special game progression unit of the present invention.

  During the short-time game, the winning probability of the normal symbol is high (1 / 1.01), the first stage lottery (ordinary symbol game) is finished with high probability, and the second stage lottery (special symbol) It is easy to generate big hits. For this reason, when winning a short-time game start lottery after 10 big-hit games by probability change game have been completed and the short-time game has started, it is easy to generate a big-hit again after the big-hit game is once finished (returning the big hit) Easy to play).

In the present embodiment, the maximum number of changes (100 times) of the special symbol in the short time game is set to be sufficiently larger than the winning probability (1/10) of the special symbol in the short time game. Specifically, when the number of lotteries is A and the winning probability is 1 / B, the probability of winning in the A lottery is determined by 1- (1-1 / B) ^A , so the winning probability The probability of winning during 100 lotteries at 1/10 is 1− (9/10) ¹⁰⁰ ≈99.99%. For this reason, the special symbol success / failure determination result during the short-time game can be almost certainly a big hit.

The gaming machine 1 according to the present embodiment has a game characteristic that the special symbol success / failure determination is almost certainly won when the short-time game start lottery is won with a probability of 84%. For this reason, it is desirable to win the special symbol success / failure determination with a probability of 95% or more during the short-time game. The probability of winning during 50 lotteries with 1/10 winning probability is 1- (9/10) ⁵⁰ ≈ 99.48%, and the probability of winning between 30 lotteries with 1/10 winning probability Is 1− (9/10) ³⁰ ≈95.76%. For this reason, when the winning probability of the special symbol is 1/10, the special symbol variation count of the short-time game needs to be 30 times or more, and the special symbol variation frequency of the short-time game is 50 times or more. It is desirable that the special symbol change count of the short-time game is 100 times or more. Although it is preferable that the number of special symbol fluctuations in the short-time game with respect to the winning probability of the special symbol is larger, it is limited to 100 by the game rules. From the above, when the special symbol variation count of the short-time game is A and the winning probability of the special symbol is 1 / B, it is necessary to satisfy the relationship of A ≧ 3 × B, and A ≧ 5 × B It is desirable to satisfy the relationship, and it is more desirable to satisfy the relationship of A ≧ 10 × B.

  The gaming machine 1 of the present embodiment is provided with five winning holes 34 to 38. A predetermined number of prize balls are paid out in accordance with the entry of game balls into the prize winning openings 34-38. The first winning opening 34 is provided below the first normal symbol starting gate 26, and the number of winning balls is three. A game ball that has passed through the first normal symbol starting gate 26 enters the first winning opening 34. The second winning opening 35 is provided at the lower right of the central device 24, and the number of winning balls is six. Further, the third winning port 36, the fourth winning port 37, and the fifth winning port 38 are provided at the lower left of the central device 24, and the number of winning balls is ten.

  Here, the progress of the game will be briefly described. In the normal symbol game (first game) before the big hit game is started, the first normal symbol actuating gate located below the central device 24 is made by left-handing to launch a game ball aiming at the left region of the game region 21. The game ball can be passed to 26 and the normal symbol variation display can be started. In addition, since the winning openings 36 to 38 having a large number of prize balls are arranged on the left side of the game area 21, a lot of prize balls can be obtained by left-handed.

  Then, in the special symbol game (second game) after the normal symbol success / failure determination becomes a hit, the right-hand hitting the game ball is aimed at the right region of the game region 21, so that the right region of the game region 21 is A game ball can be made to enter the existing start opening 30, and a right turn can be made even during a big hit game, so that a game ball can be made to enter the big winning opening 33 a existing on the right side of the game area 21. Since a probable game (high probability game) is played after the big hit game is finished up to a predetermined number (10 in this embodiment), by making a right turn, the game ball is passed through the second normal symbol operation gate 27. The game balls can be alternately entered into the start opening 30 and the big winning opening 33a, and the game can be efficiently advanced to obtain the prize balls. Furthermore, after a predetermined number (10 in this embodiment) of the big hit game, a short-time game (special game) is played by lottery. In this case as well, the second normal symbol operating gate 27 The game ball can be passed through the start opening 30 and the big prize opening 33a.

  Next, the effect symbols displayed on the effect display device 25 will be described. The display area of the effect display device 25 is provided with an effect symbol display unit for displaying effect symbols. The effect symbol of the effect symbol display unit is displayed in conjunction with the change display and stop display of the normal symbol of the normal symbol display unit 28 and the special symbol of the special symbol display unit 31.

  The effect symbol display unit is composed of three symbol display areas including a left symbol display area in which a left symbol is displayed, a middle symbol display area in which a middle symbol is displayed, and a right symbol display area in which a right symbol is displayed. . Each symbol display area has a symbol variation direction set in a direction substantially orthogonal to the arrangement direction of these display areas, in this case, in the vertical direction (vertical direction). Each symbol display area can display symbols consisting of “1” to “9”.

  The effect symbol starts to be displayed when the normal symbol fluctuating display is started, and when the normal symbol is stopped and displayed in any one of the symbols, the effect symbol is stopped and displayed in accordance with the stop symbol of the normal symbol. Similarly, when the special symbol starts to change when the special symbol starts to be displayed, and the special symbol is stopped and displayed as one of the symbols, the directing symbol is stopped and displayed according to the stop symbol of the special symbol. The In the effect design, a combination of symbols having the same three digits corresponds to a jackpot symbol of a normal symbol or a special symbol, and a combination of symbols other than those corresponds to an off symbol of a normal symbol or a special symbol.

Note that, when the normal symbol winning / losing lottery (the first stage lottery) is performed, the effect display device 25 displays the normal symbol winning / losing lottery result. However, if the result of the normal symbol winning / losing lottery (first stage lottery) is won and the special symbol winning / failing lottery (second stage lottery) is started, the special symbol winning lottery (second stage lottery) Is displayed on the effect display device 25. In the display contents of the normal symbol display unit 28 and the special symbol display unit 31, it is difficult for the player to understand the result of the success / failure. Therefore, the player can see the result of the normal symbol or the special symbol by viewing the effect display device 25. To figure out. In this case, the success / failure result in the normal symbol display unit 28 matches the success / failure result in the effect display device 25, and the success / failure result in the special symbol display device 31 and the success / failure result in the effect display device 25 also match. . The symbols displayed on the normal symbol display unit 28 and the special symbol display unit 31 may be referred to as “ordinary symbol main symbol” and “special symbol main symbol”, respectively. On the other hand, the symbols displayed on the effect display device 25 may be referred to as “ordinary symbols pseudo symbols” and “special symbols pseudo symbols”, respectively.

  The determination of the variation pattern (variation pattern) and stop symbol of the effect symbol is configured to be performed by the sub-control unit 260 based on the variation pattern designation command transmitted from the main control unit 200. Here, the variation pattern designation command transmitted from the main control unit 200 indicates the variation pattern of the special symbol. Specifically, the variation pattern designation command indicates the variation time of the special symbol, the effect contents such as the presence or absence of the reach effect, and the like. Yes. The main control unit 200 determines a variation pattern of the special symbol at random (by random number lottery) according to the determination result of the special symbol.

Each step is repeatedly executed every time the timer is reset. In the power-off generation process S50, when a power-off occurs due to a power failure or the like, the used registers and stack pointers are saved, the payout motor is stopped, and so on, and when a system reset occurs, the process proceeds to the power-on process S100. It has become.

  The power-on process S100 is performed when the power is turned on and when the power is restored after the power is cut off. When the power is turned on, a RAM initialization process or the like is performed, and when the power is turned off, the game state is restored. The return setting is performed. In the game start process S200, detection of various switch states, update of various random numbers, prize ball control, and the like are performed.

  Next, the normal symbol game process S300 will be described based on the flowchart of FIG. First, it is determined by the normal symbol operation gate detection switches 26s and 27s whether or not the game ball has passed the normal symbol operation gates 26 and 27 (S301). As a result, when it is determined that the game ball does not pass through the normal symbol operation gates 26 and 27 (S301: NO), the process proceeds to S304. On the other hand, when it is determined that the game ball has passed through the normal symbol operation gates 26 and 27 (S301: YES), it is determined whether or not the normal symbol hold number is less than 4 (S302). As a result, when the number of normal symbols held is 4 or more (S302: NO), the process proceeds to S304. On the other hand, when the number of normal symbol hold is less than 4 (S302: YES), the normal symbol determination random number is acquired and stored in a predetermined area of the RAM of the main control unit 200 (S303). As a result, the number of normal symbol reservations increases by one.

  Next, it is determined whether or not the starting port 30 is in operation (whether or not the game is per ordinary symbol) (S304), and it is determined that the starting port 30 is in operation (or is per game per normal symbol). In the case (S304: YES), the normal symbol game process is terminated, and when it is determined that the start port 30 is not in operation (no game per normal symbol) (S304: NO), the normal symbol is changing. Whether or not (S305). As a result, when it is determined that the normal symbol is not changing (S305: NO), it is determined whether or not the normal symbol is in the stop display time (S306), and it is determined that the normal symbol is in the normal symbol display time. If this is the case (S306: YES), the process proceeds to S318, which will be described later. If it is determined that the normal symbol display time is not being reached (S306: NO), it is determined whether or not the normal symbol holding number is zero (S306: NO). S307).

  As a result, when it is determined that the number of normal symbol hold is zero (S307: YES), the normal symbol game process is terminated. On the other hand, if it is determined that the number of normal symbols held is not zero (S307: NO), the random number for determining normal symbol success / failure stored in S303 is read (S308), and normal symbol determination is performed (S309). Is set (S310). In the process of S310, when the variation shortening flag is set to ON (when the variation time shortening function is in operation), the normal symbol variation time when the variation time shortening function is activated is set, and the variation shortening flag is set to ON. If it is not set (if the fluctuation time reduction function is not in operation), the normal symbol fluctuation time when the fluctuation time reduction function is not activated is set.

  Next, the variation of the normal symbol is started (S311), and a normal symbol variation start signal indicating that the normal symbol has started to be variably displayed is transmitted to the sub-control unit 260 (S312). The normal symbol variation start signal includes a normal symbol variation start signal that is transmitted when the normal symbol starts variably displaying with a normal symbol hit / fail judgment result, and a normal symbol with a normal symbol hit / fail judgment result. Includes a normal symbol out-of-fluctuation fluctuation start signal transmitted when fluctuation display starts. The sub-control unit 260 starts the variation display of the effect symbol in the display area of the effect display device 25 along with the normal symbol variation display. Then, 1 is subtracted from the number of normal symbols held (S310).

  If it is determined in S305 that the normal symbol is changing (S305: YES), it is determined whether or not the normal symbol change time has elapsed (S314), and the normal symbol change time has elapsed. If it is determined that there is not (S314: NO), the normal symbol game process is terminated. On the other hand, if it is determined that the variation time of the normal symbol has passed (S314: YES), the variation of the normal symbol is stopped (S315), and the sub-control unit 260 indicates that the normal symbol has been variably displayed. The normal symbol fluctuation stop signal shown is transmitted (S316), and the normal symbol stop display time is set (S317).

  Next, it is determined whether or not the normal symbol stop display interval has elapsed (S318). If it is determined that the normal symbol stop display interval has not elapsed (S318: NO), the normal symbol game processing is performed. Exit. On the other hand, if it is determined that the normal symbol stop display period has elapsed (S318: YES), the normal symbol stop symbol is a combination of winning symbols that activates (opens) the start port 30. It is determined whether or not (S319). As a result, when it is determined that the stop symbol of the normal symbol is not a winning symbol combination (S319: NO), the normal symbol game process is terminated.

On the other hand, when it is determined that the stop symbol of the normal symbol is a combination of the winning symbols (S319).
: YES), the game flag per normal symbol is set to ON (S320), and the operation of the start port 30 is started (S321). When the start port 30 is actuated, the blade piece 30a opens to the left, and the start port 30 is opened.

Next, the ordinary electric accessory game process S400 will be described based on the flowchart of FIG. First, it is determined whether or not a game per normal symbol is being played (whether or not a game flag per normal symbol is ON) (S401). As a result, when it is determined that the game per normal symbol is not being played (the game flag per normal symbol is OFF) (S401: NO), the normal electric accessory game process is terminated. On the other hand, when it is determined that the game per normal symbol is being played (the game flag per normal symbol is ON) (S401: YES), it is determined whether the start port 30 is operating (S402). . As a result, when it is determined that the start port 30 is not in operation (S402: N
O) The ordinary electric game product processing is terminated. On the other hand, when it is determined that the start port 30 is in operation (S402: YES), it is determined whether the operation time of the start port 30 has elapsed (S403), and the operation time of the start port 30 has elapsed. If it is determined that the process has been performed (S403: YES), the process proceeds to S405. On the other hand, if it is determined that the operating time of the start port 30 has not elapsed (S403: NO), whether or not the specified number of winnings (5 in this embodiment) has been won at the starting port 30 (specified number). It is determined whether or not a game ball has entered (S404).

  As a result, when it is determined that there is no predetermined number of winnings in the starting port 30 (S404: NO), the ordinary electric game game process is terminated. On the other hand, when it is determined that a predetermined number of winnings has been won at the starting port 30 (S404: YES), and when it is determined that the operating time of the starting port 30 has elapsed (S404: YES), the engine is started. The operation of the mouth 30 is stopped (S405). When the start port 30 is deactivated, the pair of blade pieces 30a are closed, and the start port 30 is in a closed state (normal state). Then, the game symbol per normal symbol is set to OFF (S406).

  Next, the special symbol game process S500 will be described based on the flowcharts of FIGS. As shown in FIG. 7A, first, it is determined whether or not the start port 30 is open (S501). As a result, when it is determined that the start port 30 is not open (S501: NO), the process proceeds to S505. On the other hand, when it is determined that the start port 30 is open (S501: YES), it is determined whether or not the start port 30 has been won (S502). As a result, when it is determined that the start opening 30 is not won (S502: NO). The process proceeds to S505. On the other hand, when it is determined that the start opening 30 has been won (S502: YES), it is determined whether or not the number of special symbol reservations is less than 4 (S503). As a result, when it is determined that the number of special symbol hold is less than 4 (S503: YES), a special symbol random number (symbol success / failure determination information) is acquired and stored (S504). The special symbol random number includes a special symbol success / failure determination random number, a special symbol hitting symbol determination random number, a reach random number, and the like. Thereby, the number of special symbol reservation increases by one.

  Next, it is determined whether or not a big hit game is being played (S505). As a result, if it is determined that the game is a big hit game (S505: YES), the special symbol game process is terminated. If it is determined that the game is not a big hit game (S505: NO), the special symbol changes. It is determined whether it is in the middle (S506). As a result, when it is determined that the special symbol is changing (S506: YES), the process proceeds to S513 described later, and when it is determined that the special symbol is not changing (S506: NO). Then, it is determined whether or not it is during the special symbol stop display time (S507).

  As a result, if it is determined that it is during the special symbol stop display time (S507: YES), the process proceeds to S517 described later, and if it is determined that it is not during the special symbol stop display time ( S507: NO), it is determined whether or not the number of special symbol hold is zero (S508). As a result, if it is determined that the number of special symbol hold is zero (S508: YES), the special symbol game process is terminated. On the other hand, if it is determined that the number of reserved special symbols is not zero (S508: NO), a random number for determining whether or not a special symbol is stored in a predetermined area (holding storage area) of the RAM of the main control unit 200 (starting port) The random number for determining whether or not the game ball has entered 30 is read (S509), and a special symbol determination process is performed (S510). Here, the special symbol success / failure determination processing will be described based on the flowchart of FIG.

  First, it is determined whether or not the probability variation flag is ON (whether or not the probability variation function is in operation) (S510a). As a result, if it is determined that the probability variation flag is ON (the probability variation function is in operation) (S510a: YES), the probability variation game success / failure determination table is selected (S510b), and the probability variation flag is not ON. If it is determined that the probability variation function is not in operation (S510a: NO), the normal game success / failure determination table is selected (S510c).

  Next, it is determined whether or not the result of the determination is a big hit (S510e) by using the determination table selected in S510b or S510c (S510d). As a result, when it is determined that the game is a big hit (S510e: YES), the symbol determining random number (game ball to the start port 30) stored in a predetermined area (holding storage area) of the RAM of the main control unit 200 is determined. A special symbol determining random number obtained at the time of entering the ball is read (S510f), and a big hit symbol is determined (S510g). On the other hand, when it is determined that the result of the determination is “no” (S510e: NO), a declining symbol determination random number is acquired to determine the losing symbol (S510h).

  Next, returning to FIG. 7A, a special symbol variation start process is executed (S511). Here, the special symbol variation start process will be described based on the flowchart of FIG.

  First, it is determined whether or not the result of the special symbol success / failure determination is a big hit (S511a). As a result, when it is determined that it is a big hit (S511a: YES), the big hit time variation pattern table is set (S511b), and when it is determined that it is out (S511a: NO), the fluctuation at the time of loss A pattern table is set (S511c).

  Next, a random number for determining a variation pattern is acquired (S511d), and the variation pattern of the special symbol is determined using the variation pattern table set in S511b or S511c (S511e). Then, the variation display of the special symbol is started (S511f), and the variation pattern designation command indicating the variation pattern of the special symbol and the special symbol stop information designation command indicating the type of the special symbol stop symbol are transmitted to the sub-control unit 260. (S511g).

  Next, returning to FIG. 7A, if it is determined in S506 that the special symbol is changing (S506: YES), whether or not the changing display time of the changing special symbol has elapsed. Is determined (S513 in FIG. 7B). As a result, when it is determined that the special symbol variation display time has not elapsed (S513: NO), it is determined that the special symbol game processing is terminated and the special symbol variation display time has elapsed. In this case (S513: YES), the special symbol variation is stopped (S514), and a special symbol variation stop signal indicating that the variation display of the special symbol is stopped is transmitted to the sub-control unit 260 (S515). The stop display time is set (S516).

  Next, it is determined whether or not the special symbol stop symbol display time has elapsed (S517). As a result, when it is determined that the special symbol stop symbol display time has not elapsed (S517: NO), the special symbol game processing is terminated and it is determined that the special symbol stop symbol display time has elapsed. If it is determined (S517: YES), it is determined whether or not the special symbol stop symbol is a big hit symbol (S518). As a result, if it is determined that the stop symbol of the special symbol is a jackpot symbol (S518: YES), the jackpot game flag is set to ON (S519). Thereby, the big hit game is started.

  Next, it is determined whether or not the probability variation flag is ON (S520). If it is determined that the probability variation flag is ON (S520: YES), the probability variation flag is set to OFF (S521) and the variation is reduced. The flag is set to OFF (S522), and the release extension flag is set to OFF (S523). Thereby, with the start of the big hit game, the probability variation function, the variation time shortening function, and the open time extension function are deactivated.

  On the other hand, when it is determined that the probability variation flag is not ON (S520: NO), it is determined whether or not the fluctuation shortening flag is ON (S524). As a result, when it is determined that the variation shortening flag is not ON (S524: NO), the special symbol game process is terminated, and when it is determined that the variation shortening flag is ON (S524: YES), The fluctuation shortening flag is set to OFF (S522), and the open extension flag is set to OFF (S523). As a result, with the start of the big hit game, the variable time shortening function and the open time extending function are deactivated.

  If it is determined in the determination process of S518 that the special symbol stop symbol is not a big hit symbol (S518: NO), it is determined whether or not the fluctuation shortening flag is ON (S525). As a result, when it is determined that the fluctuation shortening flag is not ON (S525: NO), the special symbol game process is terminated, and when it is determined that the fluctuation shortening flag is ON (S525: YES), The fluctuation shortening counter is decremented by 1 (S526), and it is determined whether or not the fluctuation shortening counter is zero (S527).

  As a result, when it is determined that the fluctuation shortening counter is not zero (S527: NO), the special symbol game process is terminated, and when it is determined that the fluctuation shortening counter is zero (S527: YES), The fluctuation shortening flag is set to OFF (S522), and the open extension flag is set to OFF (S523). As a result, the variable time shortening function and the open time extending function are deactivated.

  Next, the special electric accessory game process S600 will be described based on the flowchart of FIG. First, it is determined whether or not a big hit game is being played (S601). If it is determined that no big hit game is being played (S601: NO), the special symbol game process is terminated and it is determined that a big hit game is being played. If it is determined (S601: YES), it is determined whether or not the special winning opening 33a is being opened (S602). Here, whether or not the big hit game is in progress is determined by referring to the “big hit game flag” set to ON in the process of S519 shown in FIG. By determining whether it is set to ON).

  If it is determined in S602 that the grand prize opening 33a is open (S602: YES), it is determined whether or not the opening time of the big prize opening 33a has passed (S603), and the big prize opening is determined. If it is determined that the opening time of 33a has not elapsed (S603: NO), it is determined whether or not a prescribed number (one in this embodiment) has won a prize winning opening 33a (S604).

  As a result, if it is determined that the specified number (one in this embodiment) has not won in the big prize opening 33a (S604: NO), the special electric accessory game process is terminated, and the big prize opening 33a. When it is determined that the prescribed number (1 in this embodiment) has won (S604: YES) or when it is determined that the opening time of the big winning opening 33a has elapsed (S603: YES) ), The special winning opening 33a is closed (S605).

  When it is determined in S602 that the special winning opening 33a is not being opened (S602: NO), it is determined whether or not the big hit game ending condition is satisfied (S606). In this embodiment, when the number of rounds of the big hit game reaches “2”, the end condition of the big hit game is satisfied. As a result, when it is determined that the condition for ending the big hit game is not satisfied (the number of rounds has not reached 2) (S606: NO), the closing time (interval time) of the big winning opening 33a has elapsed. Is determined (S607), and when it is determined that the closing time of the special winning opening 33a has not elapsed (S607: NO), the special electric accessory game process is terminated, and the special winning opening 33a is finished. If it is determined that the closing time has elapsed (S607: YES), the special winning opening 33a is opened (S608).

  If it is determined in S606 that the big hit game end condition is satisfied (the number of rounds has reached 2) (S606: YES), the big hit game end process is executed (S609). Here, the process at the end of the big hit game will be described based on the flowchart of FIG.

  First, the big hit game flag is set to OFF (S609a). As a result, the big hit game ends. Then, it is determined whether or not the predetermined number (10 in this embodiment) of big hit game has ended (S609b). As a result, when it is determined that the predetermined number (10 in the present embodiment) of big hit games has not ended (S609b: NO), the probability variation flag is set to ON (S609c), and the variation shortening flag is turned on. (S609d), and the release extension flag is set to ON (S609e). As a result, the probability variation function, the variation time shortening function, and the open time extension function start to operate, and the probability variation game starts. Then, a short time period (operation period of the variable time reduction function and the open time extension function) is set (S609f). The short time period in the probability variation game is set until the next big hit (until the number of special symbol fluctuations reaches 10,000). The operating period of the fluctuation time shortening function and the opening time extension function is set as the above-described fluctuation shortening counter.

  If it is determined in the determination process of S609b that the predetermined number (10 in this embodiment) of big hit game has been completed (S609b: YES), it is determined whether or not to start the short-time game. (S609h). The short-time game start lottery may be performed based on the type of jackpot symbol that triggered the start of the jackpot game at the end of the predetermined number of times (the tenth jackpot game). In this embodiment, the winning probability of the short-time game start lottery is 84%.

Next, it is determined whether or not the result of the short-time game start lottery is winning (S609i). If it is determined that the winning is determined (S609i: YES), the fluctuation shortening flag is set to ON (S609d). Then, the release extension flag is set to ON (S609e), and the short time period is set (S609f). As a result, the variable time shortening function and the open time extending function start to operate, and the short time game starts. The short time period in the short time game is set until the special symbol variation count reaches 100 times. On the other hand, when it is determined that the winning is not made (S609i: NO), the fluctuation shortening flag is set to OFF (S609j), and the release extension flag is set to OFF (S6).
09k).

  Here, the correspondence between the processing shown in the flowcharts of FIGS. 5 to 11 and the present invention will be described. The processing of S300 (FIG. 5) corresponds to the first game progression means, and the processing of S500 (FIG. 6). (A), FIG. 6 (b)) corresponds to the second game progress means, the processing of S504 (FIG. 6 (a)) corresponds to the holding storage means of the present invention, and the processing of S525-S527, S609c-S609f. (FIG. 7 (b), FIG. 11) corresponds to the high-probability game progression means, the process of S609h (FIG. 11) corresponds to the special game start determining means, and the processes of S525-S527 and S609d-S609f (FIG. 7 ( b) and FIG. 11) correspond to special game progression means.

  In the present embodiment described above, the probability variation game in which the probability variation function and the open time extension function are activated after the big hit game is finished up to a predetermined number of times (9 in this embodiment). As a result, the opening frequency of the start port 30 is improved, and the winning probability of the special symbol success / failure determination is improved, so that a state in which ten big hit games continue (so-called continuous change) can be surely generated.

  Also, in this embodiment, a short-time game start lottery (winning probability 84%) is performed according to the type of special symbol that was the last big hit among the big hits of a predetermined number of times (10 in this embodiment). If the lottery result is a win, a time-short game with a special symbol variation count of 100 is started after the big hit game is over. In short-time games, the probability of winning a normal symbol is high, so it is easy to shift to a special symbol game (the second stage lottery), and it is easy to generate a big hit again (easily pull back the big hit).

  In addition, in this embodiment, the maximum variation count (100 times) of the special symbol of the short-time game is set to be sufficiently larger than the winning probability (1/10) of the special symbol, so during the short-time game The result of the special symbol success / failure determination (the second stage lottery) can be almost certainly a big hit.

  On the other hand, if the short-time game does not start due to the result of the short-time game start lottery (outgoing probability 16%), if the special symbol random number is stored (held) when the big hit game ends, the first stage The second stage special symbol success / failure determination can be executed without going through the normal symbol success / failure determination. Since the opening time of the start port 30 is 5.8 seconds, in most cases, four special symbols are stored. Thereby, after the big hit game is once ended, it is possible to provide a gameability that is easy to generate a big hit again (easy to pull back the big hit), and to improve the game entertainment. If the special symbol random number is not stored (held) when the big hit game ends, the game returns to the normal symbol game at the first stage.

  In this embodiment, the winning probability (1/135) of the normal symbol success / failure determination (first stage lottery) is set lower than the winning probability (1/10) of the special symbol success / failure determination (second stage lottery). Therefore, when the special symbol random number is stored (held) at the end of the big hit game, the high probability special symbol success / failure determination can be executed without going through the low probability normal symbol success / failure determination. As a result, it is possible to provide gameability that can easily generate a big hit again after the big hit game is finished, and it is possible to easily create an opportunity for a player advantage.

(Second embodiment)
Next, a second embodiment of the present invention will be described. In the following, the description will focus on the differences from the first embodiment.

  FIG. 12 is a front view showing a board configuration of the gaming machine 1 of the second embodiment. As shown in FIG. 2, in this embodiment, the big winning device 33 is provided at the lower right of the central device 24 and below the start port 30 and is arranged away from the start port 30.

  In the second embodiment, the opening time of the big winning opening 33a is set to 30 seconds, and the maximum number of consecutive rounds of the big hit game is set to 15 rounds. In addition, the probability variation game does not start with a probability of 100% after the predetermined number of jackpot games is completed, the probability that the result of the special symbol success / failure determination is a probability variation jackpot is 70%, and the probability of a normal jackpot is likely. 30%. When the result of the special symbol success / failure determination is a normal jackpot, the short-time game is played without performing the short-time game start lottery after the big hit game ends.

  That is, in the first embodiment, the probability that the special symbol stop symbol is determined to be “probable big hit symbol” at the time of big hit is limited to 100% (10th time), up to a predetermined number (9 times) of big hit game execution. The big hit game is forced to end with a big hit symbol other than the probable big hit symbol). On the other hand, in the second embodiment, the probability that the special symbol stop symbol is determined to be “probability big hit symbol” at the time of big hit is set to “70%”, and the special symbol stop symbol at the time of big hit is “temporal bonus hit symbol”. The probability of being determined at “30%” is set.

  That is, in the second embodiment, during the probability variation game, there is a possibility that the “short-term big hit symbol” may be stopped and displayed with a probability of 30% instead of the “probability big hit symbol” as a trigger for starting the big hit game. And different. In the second embodiment, when a big hit game triggered by a stop display of a short-term big hit symbol is executed during a probability change game, the probability change even before the big hit game is executed a predetermined number of times (9 times). The game ends. In this case, the number of executions of the big hit game in the probability variation game is cleared (initialized), and in the subsequent games, the time-short game of the first embodiment (the time-short game that continues until the number of changes of the special symbol reaches 100 times) Done. If the jackpot game is executed 9 times in succession with the probability change jackpot stoppage displayed as a trigger, as in the first embodiment, “a jackpot symbol other than the probability bonus jackpot symbol (normal jackpot symbol or short time bonus symbol) "Is stopped and displayed as an opportunity to execute the 10th big hit game, and the probability variation game is terminated.

  Further, in the second embodiment, as in the first embodiment, the frequency at which the start port 30 is opened during the short-time game is improved to increase the rate of entering the start port 30. For this reason, during the short-time game, even if the winning probability of the special symbol is low (1/10), the special symbol success / failure determination result is “big hit” by the time the special symbol variation count reaches 100 times. The determination result can be obtained almost certainly. Therefore, even if the hourly and big bonus symbol is stopped and displayed during the probability variation game, the big hit game can be executed again during the subsequent hourly game. If the newly generated jackpot game is a jackpot game triggered by the stop display of the probability change jackpot symbol, the probability change game can be executed again after the jackpot game ends. The probability change game again ends or continues under the same conditions as described above.

  Here, the special symbol success / failure determination process of the second embodiment for realizing the above-described game performance will be described. The flowchart showing the special symbol success / failure determination process is the same as that in the first embodiment (see FIG. 8). In the second embodiment, when determining the jackpot symbol in S510g in FIG. 8, the symbol determination described below is performed. The jackpot symbol is determined using either one of the tables A and B.

  The symbol determination tables A and B will be described with reference to FIG. The symbol determination table A in FIG. 13A is a symbol determination table used for determining the big hit symbol until the big hit game is continuously executed nine times triggered by the stop display of the probability variation big hit symbol. In the symbol determination table A, the hourly and big bonus symbol and the probable variation bonus symbol are associated with a special symbol determining random number (any one of random numbers 1 to 100). Specifically, a special symbol determination random number is associated (corresponding to random numbers 1 to 30) so that the time junior large winning symbol is determined with a probability of “30%”, and the probability that the probability variation big winning symbol is “70%” Are associated with special symbol determination random numbers (corresponding to random numbers 31 to 100). The symbol determination table B is also used for determining a big hit symbol during normal gaming (when determining a big hit symbol for the first time). In addition, the number of times that the big hit game that is triggered by the stop display of the probability change big win symbol can be identified by referring to the count value of a “probability change counter” described later.

  In addition, the symbol determination table B in FIG. 13B is a symbol determination table that is used after the jackpot game is triggered nine times in succession triggered by the stop display of the probability variation jackpot symbol. In other words, it is a symbol determination table used when determining the symbol at the time of the big hit that becomes the tenth time including the first big hit (the first hit at the time of normal game) in the probability variation big hit symbol. As described above, when the jackpot game is executed nine times in succession with the stop display of the probability variable jackpot symbol, the probability jackpot game is terminated by the next jackpot game. It is necessary to execute with a big hit symbol other than (a normal big hit symbol or a short time big hit symbol) as an opportunity. For this reason, in the symbol determination table B, only the “short-time jackpot symbol” and the “ordinary jackpot symbol” include the special symbol determination random numbers (any one of 1 to 100) acquired when the game ball enters the start port 30. Random number). Specifically, a special symbol determining random number is associated (corresponding to random number values 1 to 84) so that the “short and large jackpot symbol” is determined with a probability of “84%”, and the normal jackpot symbol is “16%”. Are associated with random numbers for determining special symbols (corresponding to random values 85 to 100). This is the same as in the first embodiment. Whether or not the big hit game triggered by the stop display of the probable big hit symbol is continuously executed nine times can be specified by referring to the count value of the “probable change counter” described later.

  In addition, about each symbol display mode (display mode of two LED of the special symbol display part 31) of each of the above-mentioned "probability variation big hit symbol", "time and short big hit symbol", and "normal big hit symbol", the symbol determination tables A and B It is good also as a different symbol display mode in each, and is good also as the same symbol display mode. For example, when different symbol display modes are used for each of the symbol determination tables A and B, the symbol display mode indicating the “time and big hit symbol symbol” of the symbol determination table A is “left LED: red lit, right LED: blue lit”. And the symbol display mode indicating the “short and large winning symbol” in the symbol determination table B is “left LED: blue lit, right LED: red lit”. In this way, by setting the symbol display mode of the big hit symbol to different display modes for the big hit during the probability change game and the big hit at the end of the probability change game, it is possible to clearly design the setting for changing the game state Therefore, the effect that the gaming machine design becomes easy can be obtained. As another form, when the same symbol display mode is used in the symbol determination tables A and B, the symbol display mode indicating the “time / short-time hit symbol” in the symbol determination tables A and B is “left LED: red”. It may be shared as “lighting, right LED: blue lighting”. Further, as a different form, only the portion of the special symbol determination random number for which the winning range of “time and college winning symbol” overlaps in the symbol determination tables A and B (range of random numbers 1 to 30) is the same. (For example, “Left LED: Red light, Right LED: Blue light”), the winning range of “Time and college winning symbol” is different in the portion where the symbol determination tables A and B do not overlap (range of random values 31 to 100) It is good also as a symbol display mode. In this way, the player can view the special symbol display section by sharing the symbol display mode of some or all of the jackpot symbols for the jackpot during the odd-change game and the jackpot at the end of the odd-change game. However, the effect of making it difficult to identify the type of jackpot is obtained. In the second embodiment, the symbol display modes of the jackpot symbols set in each of the symbol determination tables A and B are all different display modes.

  Next, the big hit game end process (S709) of the second embodiment will be described based on the flowchart of FIG. First, the big hit game flag is set to OFF (S709a). As a result, the big hit game ends. Next, it is determined whether or not the jackpot symbol that triggered the end of the jackpot game is “probability big hit symbol” (S709b). As a result, when it is determined that the symbol is a probability variation big hit symbol (S709b: YES), the probability variation flag is set to ON (S709c), and the probability variation counter is incremented by "+1" (S709d). Here, the “probability change counter” is a counter for specifying how many times the big hit game has been continuously executed triggered by the stop display of the “probability big hit symbol”. Every time a big hit game triggered by is executed, the count value is incremented by “1” and stored. The count value of the probability variation counter is also referred to when selecting the symbol determination tables A and B described above.

  After the probability variation counter is set to “+1”, the variation shortening flag is set to ON (S709e), and the release extension flag is set to ON (S709f). As a result, the probability variation function, the variation time shortening function, and the open time extension function are started, and the probability variation game is started. Then, a short time period (operation period of the variable time reduction function and the open time extension function) is set (S709g). The short time period in the probability variation game is set until the next big hit (until the number of special symbol fluctuations reaches 10,000).

  If it is determined in S709b that the jackpot symbol that triggered the end of the jackpot game is not “probable variation jackpot symbol” (S709b: NO), the jackpot symbol that triggered the termination of the jackpot game that ended. It is determined whether or not “Short and Big Time Winning Symbol” has been reached (S709h). As a result, when it is determined that the symbol is a time-short-hit symbol (S709h: YES), the count value of the probability variation counter is cleared (initialized) (S709i). Thereafter, the fluctuation shortening flag is set to ON (S709e), and the open extension flag is set to ON (S709f). As a result, the variable time shortening function and the open time extending function start to operate, and the short time game is started. Then, a short time period (operation period of the variable time reduction function and the open time extension function) is set (S709g). The short time period in the short time game is set until the number of times the special symbol fluctuates reaches 100 times.

  On the other hand, if it is determined in the determination process of S709h that the jackpot symbol that triggered the terminated jackpot game is not the "short-time jackpot symbol" (S709h: NO), the triggering event for the terminated jackpot game is triggered. It can be specified that the jackpot symbol was “normal jackpot symbol”. In this case, the count value of the probability variation counter is cleared (S709l), and thereafter, the fluctuation shortening flag and the release extension flag are turned OFF, and the process ends (S709j, k). As a result, the normal game in which the variable time shortening function and the open time extending function are not activated is started.

  With such a configuration of the second embodiment, the following unique game characteristics can be obtained. That is, if a jackpot game triggered by a stop display of a short-term big hit symbol is executed before the jackpot game triggered by the stop display of the probability variable jackpot symbol is executed nine times in succession (30% probability), Probability game is over and short-time game is started. At this time, the short game continues until the special symbol out-of-range display is performed 100 times. In addition, during the short-time game, the frequency of the game ball entering the start opening 30 is improved, and it is easier to execute a big hit game before the special symbol change display is performed 100 times ( Because the special symbol jackpot probability is set to 1/10). If the new jackpot game started during the short-time game is a jackpot game triggered by the stop display of the probability change jackpot symbol, the probability change game is started again after the jackpot game ends. Since this probability variation game is started from a state in which the probability variation counter is initialized, “10 big hit game executions” which is the end condition of the probability variation game is newly counted from 1. As a result, during the probability-changing game, every time the big hit game triggered by the stop display of the short and big jackpot symbol is executed, the end of the continuous execution of the big hit game is delayed. It is possible to achieve a unique gameplay of “

  Furthermore, in the second embodiment, it is possible to change the amount of balls that can be obtained by the player in accordance with the timing when the above-described “addition of an advantageous period” is performed. That is, in the case of the configuration of the second embodiment, for example, when a jackpot game triggered by a stop display of a probability variable jackpot symbol is executed twice in succession and then a time bonus symbol is stopped and displayed, the probability variation game is once ended. The amount of game balls (amount of balls) acquired by the player at this time is the amount of balls (X) corresponding to two big hit games. Further, in the second embodiment, as described above, even if the probability change game is once ended by the stop display of the time-short-hit symbol, as described above, the big-hit game can be executed again during the time-short game. For this reason, the expected amount of balls that a player can obtain by continuously executing a series of jackpot games is “the number of balls played in two consecutive jackpot games (X) + the number of balls in successive jackpot games (Y ) ”.

  On the other hand, if the jackpot game is stopped and displayed after the jackpot game is executed 8 times in succession, the amount of game balls that the player can acquire at that time is It is the amount of balls (Z (> X)) corresponding to the game. In this case, the expected amount of balls that a player can obtain by continuously executing a series of jackpot games is “the number of balls that have been played in eight consecutive jackpot games (Z) + the number of balls that have been played in subsequent jackpot games ( Y) ". That is, as the jackpot game is executed with the number of times close to the “maximum number of consecutive times of probability variation big hit game (9 times in the second embodiment)” which is the end condition of the probability variable game, The expected amount of balls that can be obtained by the player by continuously executing the big hit game is increased. For this reason, it is possible to realize a new game characteristic such as “the more the time-hit symbol is stopped and displayed just before the probability change game end condition is reached, the more advantageous to the player”.

  Also, in the second embodiment, the probability that the jackpot game is stopped and displayed after nine consecutive hits of the jackpot game triggered by the probability change jackpot symbol stop display (the jackpot symbol is stopped and displayed at the tenth jackpot). Is less than the probability (30%) that the short and big hit symbol is stopped and displayed before that (before the jackpot game is continuously executed nine times triggered by the stop indication of “probable big hit symbol”) It is set high. Thereby, the continuous execution of the big hit game can be realized in the game progress mode in which the “assumed amount of balls” is maximized, and the game interest of the player can be effectively enhanced.

  Even in the configuration of the second embodiment, when the special symbol random number is stored (held) at the end of the big hit game, the second symbol normal symbol success / failure determination is not performed. The special symbol success / failure determination at the stage can be executed. Thereby, after the big hit game is once ended, it is possible to provide a gameability that makes it easy to generate a big hit again (easy to pull back the big hit), and it is possible to create an opportunity for a player advantage.

  Next, a third embodiment will be described. The third embodiment is characterized in that, when the big hit symbol is determined in S510g of FIG. 8, the big hit symbol is determined using one of the symbol determination tables C and D of FIG.

  The symbol determination table C in FIG. 15 (a) is a symbol determination table used for determining the big hit symbol until the big hit game is executed nine times in succession triggered by the stop display of the probability variation big hit symbol (second). This corresponds to the symbol determination table A in the embodiment). In this symbol determination table C, not only the time and bonus jackpot symbol and the probability variation jackpot symbol, but also the “normal jackpot symbol” is associated with a special symbol determining random number (any one of random numbers 1 to 100). Specifically, a special design determining random number is associated (corresponding to a random number value 1 to 50) so that the probability variation big hit symbol is determined with a probability of “50%”, and the short and large jackpot symbol is “30%”. Random numbers for special symbol determination are associated (corresponding to random numbers 51 to 80), and special symbol determination random numbers are generally associated with a probability of “20%”. (Corresponding to random values 81 to 100). The symbol determination table C is also used for determining a big hit symbol during normal gaming (when determining a big hit symbol for the first time). In addition, the number of times that the jackpot game is executed continuously triggered by the stop display of the probability variation jackpot symbol can be specified by referring to the count value of the “probability variation counter” described above. In addition, the symbol determination table D of FIG.15 (b) is a symbol determination table used at the time of the jackpot symbol determination after the jackpot game continuously performed 9 times triggered by the stop display of the probability variation jackpot symbol, Since it is the same as the symbol determination table B of the second embodiment, the description is omitted.

  In the third embodiment, when the symbol determination table C is set, the “normal jackpot symbol” is stopped and displayed before the jackpot game is triggered nine times in succession triggered by the stop display of the “probability big hit symbol”. A normal game is performed. In this case, since the short-time game is not performed after the big hit game ends, the continuous execution of the big hit game ends. From the viewpoint of the player, the start port 30 is not suddenly released, and the continuous execution of the big hit game is ended, so that the end timing of the continuous execution of the big hit game becomes difficult to predict. As a result, in addition to the above-described “addition of an advantageous period”, it is possible to add a new game that “it cannot be predicted when the continuous execution of the big hit game will end”. Even in the third embodiment, when the special symbol random number is stored (held) at the end of the jackpot game triggered by the normal jackpot symbol stop display, the normal symbol success / failure determination at the first stage is passed. The special symbol success / failure determination at the second stage can be executed without any problem. Thereby, after the continuous execution of the big hit game is finished, it is possible to provide a gameability that is easy to generate a big hit again (easy to pull back the big hit), and it is possible to create an opportunity for a player advantage.

  Next, a fourth embodiment will be described. The fourth embodiment is characterized in that the probability that various jackpot symbols are stopped and displayed changes according to the number of times that the jackpot game is continuously executed triggered by the stop display of the “probability jackpot symbol”. . For example, it is possible to change the ratio at which the “short-time big hit symbol” and the “normal big hit symbol” are stopped and displayed by continuously executing the big hit game triggered by the stop display of the probability variation big hit symbol.

  Specifically, as shown in FIG. 16, a plurality of symbol determination tables E to H are provided corresponding to the number of consecutive big hit games (probability variable counter values 0 to 9) triggered by the stop display of the probability variable big hit symbol. . The symbol determination table E in FIG. 16A is a symbol determination table used when the number of consecutive big hit games triggered by the stop display of “probability big hit symbol” is “0 (zero)”. In this symbol determination table E, special symbol determination random numbers are associated (corresponding to random numbers 1 to 50) so that the probability variation jackpot symbol is determined with a probability of “50%”. Special symbol determination random numbers are associated so as to be determined with a probability of% (corresponding to random numbers 51 to 75), and special jackpot symbols are determined so that the normal jackpot symbol is determined with a probability of "25%" Random numbers are associated (corresponding to random values 76 to 100).

  In addition, the symbol determination table F in FIG. 16B is a symbol determination table used when the number of consecutive big hit games that are triggered by the stop display of the probability variation big hit symbol is “1 to 4 times”. In this symbol determination table F, special symbol determination random numbers are associated (corresponding to random numbers 1 to 50) so that the probability variation jackpot symbol is determined with a probability of “50%”. A special symbol determining random number is associated so as to be determined with a probability of “30%” (corresponding to random numbers 51 to 80), and a special jackpot symbol is determined with a probability of “20%”. Random numbers for determination are associated (corresponding to random number values 81 to 100).

  In addition, the symbol determination table G in FIG. 16C is a symbol determination table used when the number of consecutive big hit games triggered by the stop display of the probability variation big hit symbol is “5 to 8”. This symbol determination table G is associated with special symbol determination random numbers so that the probability variation jackpot symbol is determined with a probability of “50%” (corresponding to random numbers 1 to 50). A special symbol determining random number is associated so as to be determined with a probability of “40%” (corresponding to random numbers 51 to 90), and the special jackpot symbol is determined with a probability of “10%”. Random numbers for determination are associated (corresponding to random values 91 to 100).

  In addition, the symbol determination table H in FIG. 16D is a symbol determination table used when the number of consecutive big hit games triggered by the stop display of the probability variation big hit symbol is “9” (used for the tenth big hit) Symbol determination table). In this symbol determination table H, special symbol determination random numbers are associated (corresponding to random numbers 1 to 90) so that the hourly / hit jackpot symbol is determined with a probability of “90%”, and the normal jackpot symbol is “ A special symbol determination random number is associated so as to be determined with a probability of “10%” (corresponding to random number values 91 to 100).

  According to such a configuration, as the jackpot game that is triggered by the stop display of the “probability jackpot symbol” is continuously executed, the probability that the “short-time jackpot symbol” is stopped and displayed increases. ”Is displayed in a stopped state. For this reason, as in the second embodiment, it is possible to more effectively realize the gameability such as “the more the time-short hit symbol is stopped and displayed just before reaching the end condition of the probability variation game, the more advantageous to the player”.

  Contrary to the fourth embodiment, the probability that the “short and large jackpot symbol” is stopped and displayed becomes lower as the jackpot game is continuously executed triggered by the stop display of the “probable bonus jackpot symbol”. If it is assumed that the probability that the “usually big hit symbol” is stopped and displayed is increased, it is possible to realize a game with low joyfulness while suppressing the rate of continuous execution of the big hit game.

  Next, a fifth embodiment will be described. In the fifth embodiment, the number of time-short games executed after the end of the jackpot game (time-short number of times) triggered by the stop display of the “time-short-hit symbol” is set to a different number depending on the “type of time-hit bonus symbol”. It is characterized by that.

  In the fifth embodiment, “hour and hour big hit symbol A” and “hour and hour big hit symbol B” are provided as types of hour and hour big hit symbols. Then, the number of hours after the end of the jackpot game triggered by the stop indication of “time and bonus game A” is set to “100”, and the time after the jackpot game is triggered by the stop indication of “time and bonus game B” The number of times is “10 times”. In addition, in the symbol determination table of the first to fourth embodiments described above, the allocation setting to the hourly / shortest bonus symbol is further divided and set so that it can be further divided into “time / shortest bonus symbol A” and “time / shortest bonus symbol B”. .

  For example, the symbol determination tables A and B in the second embodiment are set as symbol determination tables I and J in FIG. In the symbol determination table I of FIG. 17A, special symbol determination random numbers are associated (corresponding to random number values 1 to 20) so that the symbol A per time college symbol is determined with a probability of “20%”. A special symbol determination random number is associated (corresponding to random numbers 21 to 30) so that the jackpot symbol B is determined with a probability of “10%”, and the probability variation jackpot symbol is determined with a probability of “70%”. Are associated with random numbers for determining special symbols (corresponding to random numbers 31 to 100). In addition, the symbol determination table J is associated with a special symbol determination random number (corresponding to random numbers 1 to 74) so that the hourly and big bonus symbol A is determined with a probability of “74%”, Special symbol determination random numbers are associated so as to be determined with a probability of “10%” (corresponding to random numbers 75 to 84), and special symbol determination is performed so that the normal jackpot symbol is determined with a probability of “16%” Random numbers are associated (corresponding to random values 85 to 100).

  According to such a configuration, the following playability can be obtained. In other words, after the end of the big hit game triggered by the stop display of the hourly and big bonus symbol A, the hourly game is started with a limit of 100 special symbol outliers. In this case, the short-time game continues until the special symbol out-of-shift display is performed 100 times, so that the game performance is the same as in the second embodiment (the next big hit game is almost confirmed). On the other hand, after the end of the big hit game triggered by the stop display of the hourly and big bonus symbol B, the hourly game is started up to the limit of 10 special symbol out-of-range variations. In this case, since the probability that the special symbol will be a big hit during the short-time game is “1/10”, there is a possibility that the short-time game may end without obtaining the big hit. In this way, by setting a different number of times for each of a plurality of hourly / hit bonus symbols, it is possible to realize a unique game characteristic that “the continuation rate of the big hit game varies depending on the type of the hourly / hit bonus symbol”.
