Description

  The present invention relates to a gaming machine configured to open and close a winning opening of a winning device capable of winning a game ball flowing down a gaming area by an opening / closing means.

  A pachinko machine, which is a typical gaming machine, has a frame-shaped decorative member (a so-called center accessory) disposed at a substantially central position of a gaming area defined on the surface of the gaming board. A symbol display device such as a liquid crystal type or a drum type that displays a plurality of symbols in a variable manner via the rear face, and a symbol display device by winning a pachinko ball (game ball) at a position below the decorative member in the game board Many proposals have been proposed in which a start winning device for starting symbol variation in the game and a special winning device that is opened at the time of a big hit are arranged. In such a pachinko machine, the pachinko ball launched into the game area gradually flows down due to its own weight while bouncing off by contact with a game nail or the like implanted in the game area, and the start in the process of flowing down the game area By winning at the winning opening of the winning device, various game effects such as reach effects accompanying symbol fluctuations are made on the symbol display device, and when the symbols stop on the symbol display device in a predetermined combination, so-called big hit games or A hit game such as a small hit game is generated. Along with the occurrence of the winning game, a round game in which the opening / closing door (opening / closing means) opens the winning opening of the special winning device provided on the game board is performed, and the player receives a lot of winning balls. Opportunities that can be acquired are given, and the opening and closing doors close the winning opening of the special winning device as the winning game ends, thereby restricting the winning of the pachinko ball.

  Here, a special prize-winning device that has been widely used in pachinko machines has been pivotally supported by the opening lower edge of the prize opening that opens in the front-rear direction so that the opening / closing door can swing and a solenoid as a drive means. The open / close door is connected to the open / close door via a connection mechanism, and the open / close door closes the winning opening as the solenoid is driven, and the free end of the open / close door swings forward. And swings between the open position where the prize opening is opened. For this reason, even when the opening / closing door is in the closed position, it is possible to open and close the opening / closing door relatively easily by hooking a finger on the opening / closing door. When it is necessary to forcibly open it, it can easily cope with it. For example, at the manufacturing stage of a pachinko machine, an operator manually opens and closes the open / close door to improve the workability of the pachinko ball winning detection confirmation check. In addition, when a game is being played on a pachinko machine in an amusement store, if a predetermined prize ball is not paid out due to a failure to open or close the door, the employee of the amusement store manually opens the door. It is also possible to compensate for the shortage of prize balls by forcibly opening and winning pachinko balls.

Thus, an unauthorized opening operation of the opening / closing means can be more effectively prevented.

The gist of the invention according to claim 3 is that the locking recess (32d) is provided to be located at either the left or right end of the protrusion (32b).
Thus, by providing the locking recess so as to be positioned at either the left or right end of the protrusion, it is easy for an operator to hook a finger on the locking recess, and a manual forcible opening operation is performed. It can be done easily.

In the invention according to claim 4, the mounting plate (32) is formed with support portions (46, 46) protruding forward from left and right opening side edge portions of the winning opening (33). The obstruction means (45) is laid over the front end of the support portions (46, 46) of the support section, and the opening / closing means (42) and the obstruction means (45) are separated from each other by a distance that allows the game ball to pass therethrough. The gist is that they are configured to overlap.
As described above, the support portion protrudes from the left and right opening side edge portions of the winning opening, and the obstacle means is located in front of the opening / closing means, so that it is difficult for an unauthorized device to enter from the side or the front of the opening / closing means. Thus, an unauthorized opening operation of the opening / closing means can be more effectively prevented. In addition, if the locking recess is configured to be located at either the left or right end of the ridge, the support portion functions as a restricting unit that restricts an unauthorized device from entering the locking recess. The effect of preventing unauthorized opening operation of the means is further enhanced.

  According to the gaming machine according to the present invention, unauthorized opening operation of the opening / closing means can be prevented while allowing manual opening operation of the opening / closing means to be permitted.

The opening / closing door 42 and the shielding member 45 are configured to overlap in the front-rear direction in a state of being separated by a distance that allows the pachinko ball to pass therethrough. Further, when the open / close door 42 is displaced to the open position, the free end of the open / close door 42 is configured not to interfere with the back surface of the shielding member 45, and the open / close door 42 is in the open position. Pachinko balls that flow down the area surrounded by the base plate part 32, the shielding member 45, and the left and right support parts 46, 46 are received by the open / close door 42 and win the special prize opening 33. ing.

  As shown in FIGS. 8 and 9, the shielding member 45 is configured such that the upper end portion is located above the opening upper edge portion of the special prize opening 33, and the lower end portion of the shielding member 45 is It is comprised so that it may be located below the opening lower end edge part of the special winning opening 33. That is, the shielding member 55 is positioned in the player's line-of-sight direction (front side upper direction) with respect to the special prize opening 33, and the opening / closing door 42 for closing the special prize opening 33 is a shielding member located above the front side. 55 prevents visual recognition from the player. Further, since the shielding member 55 is positioned in front of the special winning opening 33, the free edge of the opening / closing door 42 located in the open position is hidden by the shielding member 45, and the opening / closing door 42 in the opening position is played. It is difficult to distinguish from the person. Here, the state in which the shielding member 45 is provided in the player's line-of-sight direction with respect to the special prize opening 33 is a state in which the special prize opening 33 (opening / closing door 42) is completely hidden from the player side. As described above, the upper and lower ends of the shielding member 45 are located above the upper edge of the opening of the special prize opening 33, and the door 42 is opened as compared with the state where the shielding member 55 does not exist. It includes a condition that makes it difficult to see.

  Further, as shown in FIG. 7, the upper surfaces 46a, 46a of the left and right support portions 46, 46 are formed so as to be inclined downwardly as they are spaced outward from the special prize opening 33, and the left and right support portions The upper end portions of the inner side surfaces 46b, 46b facing the special winning opening 33 in 46, 46 are configured to be located above the upper end portions of the outer side surfaces 46c, 46c. This prevents unauthorized equipment inserted into the game area 20a from reaching the opening / closing door 42 located between the left and right support portions 46, 46, and unauthorized opening of the opening / closing door 42. Making it difficult.

(About special figure display)
As shown in FIG. 2, in the lower left position of the game area 20a of the game board 20, a special indicator (symbol display means) 50 composed of a plurality of LEDs (light emitting units) is provided. When the pachinko ball is awarded to the winning openings 26a and 26b of the start winning device 26, the LED of the special-purpose indicator 50 is variably displayed (flickering fluctuation which is turned on / off), and finally the LED is steadily turned on. A special figure is represented by the lighting position (lighting pattern). In the embodiment, a special-purpose indicator composed of a plurality of LEDs (seven in the embodiment) that are displayed in a variable manner when a pachinko ball wins an upper start winning opening 26a in the start winning apparatus 26. 50a and a special-purpose display device 50b composed of a plurality of LEDs (eight in the embodiment) that are displayed in a variable manner when a pachinko ball is awarded to the lower start winning opening 26b ( (See FIG. 10 (a)). Here, the special figure is used as a notification pattern indicating the result of the internal lottery such as whether or not it is a big hit, and the special figure display 50 displays a plurality of types of special figures by combinations of LED lighting positions. It has come to be. In the symbol display device 18, a display effect (symbol variation effect) related to the special symbol variation display performed by the special symbol display 50 is performed. Specifically, in the symbol display device 18, a display effect based on a fluctuating image (or image display) is performed, and a symbol variation effect that displays a combination of symbols by varying a plurality of types of symbols (decorative drawings) in a plurality of columns. Is done. In the special figure display 50 and the symbol display device 18, the special figure fluctuation display and the decoration drawing fluctuation display are started at the same time and are simultaneously ended (that is, the special figure and the decoration drawing are displayed in a fixed stop state simultaneously).

  In the embodiment, the special figure display 50 selects one special figure corresponding to the lottery results of the big hit lottery and the small lottery lottery from a plurality of types (61 types in the embodiment) of special figures, and the special figure variation is selected. The special figure selected along with the end of the display is individually displayed in a fixed stop state. The special figure displayed on the special figure display 50 includes 50 kinds of big hit symbols (corresponding to the big hit display result) that can recognize a big hit and 10 types that can recognize a big hit. There are two types of small hit symbols (corresponding to the small hit display result) and one type of missing symbols that can be recognized as missing symbols. Then, when the big hit symbol is displayed on the special figure display 50, the big hit game is given to the player. Further, when the small hit symbol is displayed, the player is given a small hit game. The big hit game and the small hit game set in the pachinko machine 10 of the embodiment will be described in detail later. The small hit lottery is performed when the big hit lottery is not won.

  The symbol display device 18 displays eight types of numbers “0” to “7” in the left and right columns as decorative figures, and eight types of numbers “0” to “7” in the center column and The letter “A” is displayed as a decorative drawing. Then, when the decorative drawings of all the columns stopped and displayed on the symbol display device 18 are of the same type, it is possible to recognize the occurrence of the big hit to which the big hit game is given from the symbol combination (such as “777”). The symbol combination that can recognize the jackpot is a jackpot symbol combination (big hit display result) by a decorative drawing. When the jackpot display is confirmed and stopped as a result of the symbol variation effect, the jackpot game is given to the player thereafter. On the other hand, in the case where the decorative symbols of all the columns displayed on the symbol display device 18 are stopped and displayed are of different types, or when the symbols of one column are different from the symbols of the other two columns, in principle, the symbol combination ( "123" etc.) can be recognized. The symbol combination that can recognize the deviation is a symbol combination (outlier display result) of the deviation based on the decorative drawing. In addition, when a predetermined symbol combination is displayed among out-of-order symbol combinations (in the example, “A” is displayed in the center column), a big hit game or a small hit game may be given. Can be recognized. A symbol combination that suggests the possibility that a probability variation state in which the probability of jackpot determination is from low probability to high probability is assigned to a symbol combination that can recognize that this jackpot game or small hit game may be awarded It becomes.

  When the jackpot symbol is displayed on the special symbol display 50 as a fixed stop display, as a rule, the symbol combination on the symbol display device 18 (for example, “333”) is fixedly stopped and displayed. . Further, when the off symbol is stopped and displayed on the special symbol display 50, the off symbol combination (for example, “754” or the like) is also displayed on the symbol display device 18 in a fixed stop manner. In addition, when the small hit symbol is stopped and displayed on the special symbol display 50, the symbol combination (“A” in the center column) suggesting the probability change is also displayed on the symbol display device 18 in a fixed stop manner. . In addition, the symbol combination of the decorative drawing for the special drawing is not necessarily in a one-to-one relationship, and the symbol combination by one decorative drawing is selected from the symbol combinations by a plurality of decorative drawings for one special drawing. It has come to be.

(About special figure hold)
In addition, as shown in FIG. 2, at the lower right position of the game board 20, the number of stored start balls stored in the inside of the machine (RAM 30c) is stored in the inside of the machine (RAM 30c) by winning the upper start winning opening 26a. A first special figure holding display 51 composed of a plurality of LEDs to be displayed (four in the embodiment) is arranged, and a prize is given to the lower start winning opening 26b to become a start holding ball. There is provided a second special figure holding indicator 52 composed of a plurality of LEDs (four in the embodiment) for displaying the number of starting and holding balls stored in (RAM 30c). The number of special figure variation displays (symbol variation effects) that are suspended is notified by the display contents of the special figure hold indicators 51 and 52.

  Here, the first special figure start holding storage number displayed on the first special figure hold indicator 51 is incremented by 1 when the pachinko ball wins the upper start winning opening 26a, and the special figure fluctuation display is also made. 1 is subtracted when (symbol variation effect) is performed. Similarly, the second special figure start reserved memory number displayed on the second special figure hold indicator 52 is incremented by 1 when the pachinko ball wins the lower start winning opening 26b, and the special figure change is also made. 1 is subtracted by the display (design variation effect). Note that a predetermined upper limit number (“4” in the embodiment) is set for the first and second special figure start reserved memory numbers, and the first and second special figure start hold memory numbers are added to the upper limit number. It is set to be able to. Each of the first and second special figure hold indicators 51 and 52 is composed of a plurality of (four in the embodiment) LEDs, and there are as many LEDs as the number of corresponding special figure start hold memories. By lighting up. It is possible to grasp the number of holdings for which special figure fluctuation display is performed.

(Regarding the general-purpose display)

In the general map display 53, a general map change display for deriving one general map by varying a plurality of types of normal symbols (hereinafter sometimes referred to as “general map”) is performed. In the embodiment, three types are shown in the light emission mode of two LEDs. Specifically, the two LEDs are lit together, only the right LED is lit, only the left LED is lit, Multiple types of common maps are shown. In the following, for convenience of explanation, the general map shown when both LEDs are turned on is called “0”, and the general map shown when only the right LED is turned on is called “1”. The usual figure shown by turning on only the LED is the ordinary figure “2”. Then, from the final display result of the general map display 53, it is possible to recognize the normal map hit or miss. Specifically, the universal map “1” and “2” are displayed on the universal map display 53 in the case of hitting the universal map, and the universal map “0” is displayed in the case of a loss. In other words, the universal map that can recognize this universal map is the display result of the universal map, and the universal map that can recognize the disparity is the display result of the disparity.

(Regarding the general hold)
As shown in FIG. 2, a pachinko ball passes through the ball passage gate 47 at the lower right position of the game board 20 and becomes a start-up ball and is stored in the inside of the machine (RAM 30c). A general figure hold indicator 54 composed of a plurality of LEDs for displaying numbers (two in the embodiment) is arranged, and the number of fluctuations of the general figure held by the display content of the general figure hold indicator 54 is arranged. Is notified. The number of the reserved map start display displayed on the map holding display 54 is incremented by 1 when the pachinko ball passes through the ball passing gate 47 and decremented by 1 when the map variation display is started. Note that a predetermined upper limit number (“4” in the embodiment) is set for the general-purpose start reserved memory number, and the general-purpose start reserved memory number can be added up to the upper limit number. The general figure hold indicator 54 is composed of a plurality of (four in the embodiment) LEDs, and the number of LEDs corresponding to the number of common figure start and hold memories is lit. It is possible to grasp the number of holds for which the usual figure variation effect is performed.

(About probability change)
Further, the pachinko gaming machine 10 of the embodiment has a probability variation (hereinafter referred to as “probability variation”) function as a special gaming state advantageous to the player after the big hit game is over. The probability change function is a low probability (normal state) of the jackpot lottery probability (winning probability) after the jackpot game ends, provided that the type of jackpot symbol (special figure) that is confirmed and stopped is a predetermined probability variation symbol. This is a function for giving a probability variation state (probability variation state) that varies from a certain normal probability (4/1439 in the embodiment) to a high probability (33/1439 in the embodiment). In the embodiment, the jackpot to which the probability variation state is given after the jackpot game ends is the probability variation jackpot, and the jackpot to which the probability variation state is not imparted is the non-probability variation jackpot. Further, the probability variation state is continuously given after the big hit game is finished until the next big hit is generated. In this way, when a probability variation state is given, the probability of winning a big hit fluctuates with a high probability and it is easy for a jackpot to occur.Therefore, the probability variation state is advantageous to the player, and the player will become a probability variation big hit. Playing games while expecting.

(About winning rate improvement status)
In addition, when the probability variation state is given, it is determined whether or not the winning rate improvement state is given depending on the type of jackpot game, and the period when the winning rate improvement state is given (special figure) The number of variable displays) is determined. In this winning rate improvement state, the fluctuation time of the normal figure fluctuation display performed by the normal figure indicator 53 is shortened, and the probability per normal figure of the normal figure fluctuation display is a normal probability (in the embodiment, 2/107). It is a state that fluctuated with a high probability (106/107 in the embodiment). Further, in the state where the winning rate improvement state is given, the opening / closing operation is performed with an operation pattern different from the state where the winning rate improvement state is not given. Specifically, in the state where the winning rate improvement state is not given, the open state is maintained until 300 ms elapses after the opening / closing member 28 is opened when winning in the normal map display (in the case of the normal map). The opening operation is performed once. On the other hand, in the state where the winning rate improvement state is given, when the normal fluctuation display is won (in the case of the normal figure), the open / close member 28 is kept open until 1800 ms elapses after opening. The opening operation is repeated three times. That is, in the state where the winning rate improvement state is given, the total opening time of the opening and closing member 28 is longer than that in the state where the winning rate improvement state is not given, and it is set so as to operate advantageously for the player. ing.

(About time reduction)
The pachinko gaming machine 10 according to the embodiment has a time-shortening function that gives a variable time shortening state (hereinafter referred to as a “time-shortening state”) as a special gaming state advantageous to the player after the big hit game that becomes an uncertain change state. In the embodiment, it is set so that the winning rate improvement state is given as the short time state after the big hit game that becomes an uncertain change state. It should be noted that the winning rate improvement state in the short-time state is continuously given until a special figure variation display is performed a predetermined number of times (50 times in the embodiment), and the short-time state is terminated with the occurrence of the big hit. Is set.

(About jackpot games)
Next, the jackpot game given by the pachinko gaming machine 10 of the embodiment will be described. The jackpot game is set to start after the jackpot symbol is stopped and displayed on the special chart display 50 as a result of the special chart fluctuation display, and an opening effect indicating the start of the jackpot game and a regulation performed after the opening effect ends. The game is composed of a round game that is repeated by the number of rounds (two types of 15 rounds and 2 rounds in the embodiment) and an ending effect indicating the end of the big hit game. In the round game, the opening / closing door 42 of the special prize-winning device 30 opens and closes according to the type of jackpot that has occurred, and a predetermined number (for example, eight) of pachinko is placed in the special prize opening 33 in one round game. One round game ends when a ball wins or a specified time (round game time) elapses from the start of each round game. Note that, during each round game in the big hit game, an interval time for which the open / close door 42 is held in a closed state for a predetermined time (hereinafter referred to as “interval time between rounds”) is set. In other words, in the jackpot game, the opening / closing door 42 performs an opening / closing operation that exceeds the specified number of rounds for each jackpot game.

  Here, the pattern of the opening / closing operation of the opening / closing door 42 in each round game of the jackpot game includes one opening operation (from opening to closing) under the condition that the pachinko balls are continuously fired at a predetermined interval. Operation), a long-time opening operation in which a predetermined number of pachinko balls determined for a round game continue to open for a time that can be won, and the opening time of the open / close door 42 is shorter than the long-time opening operation. The time during which the pachinko ball is virtually impossible during the operation (the operation from opening to closing) or the time when the specified number of pachinko balls are not possible even if the winning time is open It is configured by appropriately combining a short-time opening operation that opens only for a short time.

(Type of jackpot game)
In the pachinko gaming machine 10 of the embodiment, nine types of jackpot games shown in FIG. 12 are set, and when the jackpot lottery is won, one jackpot game is determined and the determined jackpot game is given. It has become. Of the nine types of jackpot games, which jackpot game is awarded is determined according to the type of special figure (jackpot symbol) determined when winning the jackpot lottery. . Here, the big hit game given by the pachinko machine of the embodiment includes a 15R probability variable big hit game as a first hit game in which only the long-time opening operation is performed by the opening / closing door 42 and an opening operation including a short-time opening operation. 15R non-probable big hit game, 15R probable secret big hit game, 15R shortened probable big hit game, 15R shortened non-probable big hit game, step-up big hit game (first special probable variable big hit game) A jump-up jackpot game (second 15R special probability variable jackpot game), a 2R special probability variable jackpot game, and a 2R normal probability variable jackpot game are set. Hereinafter, an opening / closing operation pattern of the opening / closing door 42 in each jackpot game will be described.

(About 15R probability change, 15R non-change probability, 15R probability change secret big hit game)
The 15R probable big hit game, 15R non-probable big hit game and 15R probable secret big hit game are 15 round big hit games with the prescribed round number set to “15”, and the maximum number of winnings in each round game is “8” "Is set. And, in the 15R probability variable big hit game, regardless of the game state at the time of winning the big hit lottery, after the big hit game is finished, until the next big hit game is generated, the positive change state and the winning rate improvement state are given after the big hit game ends It has come to be. In addition, in the 15R probability-variant concealment big hit game, regardless of the game state at the time of winning the big hit lottery, the probability change state is given after the big hit game ends, while the predetermined number of times (50 in the embodiment) from the end of the big hit game. The winning rate improvement state is given only until the special figure variation display of) is performed. In the 15R non-probable big win game, regardless of the game state at the time of winning the big hit lottery, the promiscuous state is not given after the big hit game ends, while the short time state (winning rate improvement state) is given after the big hit game ends. It has become so.

  In each round game of 15R probability variation big hit game, 15R non-probability big hit game, and 15R probability variable secret big hit game, the opening / closing door 42 is opened for a long time to open the special prize opening 33 continuously from the start to the end of the round game. It is set to be performed. That is, all round games of the 15R probability variable big hit game, 15R non-variable big hit game, and 15R probability variable secret big hit game are all open round games in which the open / close door 42 is opened for a long time from the start to the end of the round game. It is configured. Therefore, in the 15R probability variation jackpot game, the 15R non-probability variation jackpot game, and the 15R probability variation secret jackpot game, the opening / closing door 42 is opened only once in each round game, and the opening / closing door 42 repeats the opening / closing operation 15 times in the entire jackpot game. It is like that. That is, in the 15R-probability big hit game, the 15R non-probable big hit game, and the 15R-probable secret big hit game, the open / close door 42 in each big hit game looks and opens the same.

  Here, in the 15R probability variation jackpot game, the 15R non-probability variation jackpot game, and the 15R probability variation secret jackpot game, “25 (seconds)” is set as the round game time of one round game. 42 is opened for a maximum of "25 (seconds)". In these jackpot games, “7.0 (seconds)” is set as the opening time, and “14.6 (seconds)” is set as the ending time. In addition, the interval time between rounds of these jackpot games is set to “2.0 (seconds)” except before the start of the final round, and “1.996 (seconds)” before the start of the final round. Yes.

(About 15R shortened probable big hit game and 15R shortened non-probable big hit game)
The 15R shortened probability variable jackpot game and the 15R shortened non-probable bonus game are 15 round jackpot games with the specified number of rounds set to “15”, and the upper limit number of winnings for each round game is set to “8”. The And in the 15R shortened probability variable big win game, regardless of the game state at the time of winning the big hit lottery, after the big hit game ends, until the next big hit game is generated, the probable change state and the winning rate improvement state after the big hit game ends. It is to be granted. In addition, in the 15R shortened non-probable big win game, regardless of the game state at the time of winning the big hit lottery, the promiscuous state is not given after the big hit game ends, but the short time state (winning rate improvement state) is given after the big hit game ends. It has come to be.

  In this 15R shortened probable big hit game and 15R shortened non-probable big hit game, the round games of the 1st to 8th rounds open and close the long-time opening operation that opens the special prize opening 33 continuously from the start to the end of the round game The door 42 is set to perform. On the other hand, in the round game after the 9th round of 15R shortened probability variation big hit game and 15R shortened non-probable big hit game, the special prize opening 33 is continuously opened from the start to the end of the round game, but it opens and closes by the eighth round. The opening / closing door 42 is set to perform a short-time opening operation in which the opening time of the special prize opening 33 is shorter than the long-time opening operation performed by the door 42. That is, in the 15R shortened probability variable big hit game and the 15R shortened non-probable big hit game, the opening and closing door 42 performs a long-time opening operation in which a round game of a predetermined number of times (eight times) from the first round game is opened from the start to the end of the round game. On the other hand, the remaining number of round games (for 7R) are composed of short round games that cause the opening / closing door 42 to perform a short opening operation. That is, the 15R shortened probability variable big hit game and the 15R shortened non-probable big hit game constitute a composite open hit game that causes the open / close door 42 to perform the long time opening operation and the short time opening operation.

  Here, in the 15R shortened probable big hit game and the 15R shortened non-probable big hit game, “25 (seconds)” is set as the round game time of one round game from the first round to the eighth round, and each round game The opening / closing door 42 is opened for a long time of "25 (seconds)" at the maximum. On the other hand, “0.2 (seconds)” is set as the round game time of one round game of the ninth to fifteenth rounds. In these jackpot games, “7.0 (seconds)” is set as the opening time, and “14.6 (seconds)” is set as the ending time. In addition, the interval time between rounds of these jackpot games is set to “2.0 (seconds)” except before the start of the final round, and “1.996 (seconds)” before the start of the final round. Yes. As a result, in the 15R shortened probable big hit game, the time from when the open / close door 42 of the special prize-winning device 30 opens in the ninth round to when the open / close door 42 of the special prize-winning device 30 closes in the 15th round ("13.4 (Seconds) ") is the same as the time from the first opening of the open / close door 42 to the seventh closing in the ninth round of the step-up jackpot game.

  The round game time (0.2 (seconds)) after the 9th round in 15R shortened probabilistic big hit game and 15R shortened non-probable big hit game is the number of pachinko balls that will win the special prize device 30 in one round game. Is set to a time that does not meet the maximum number of winnings. Incidentally, in the pachinko gaming machine 10, since the number of pachinko balls fired per minute is set to approximately “100 balls”, the time required to launch one pachinko ball is “0.6 (seconds)”. It becomes. In other words, in the round game after the 9th round of 15R shortened probability variation big hit game and 15R shortened non-probability big hit game, it is practically impossible to win the “8 balls” pachinko ball that is the upper limit number of winnings within the round game time. The opening operation is performed for a short period of time, which is substantially equal to the number of winning balls (that is, the number of winning balls) in the round game for 8 rounds in the 15R probability variable big hit game described above. Accordingly, in the 15R shortened probability variation big hit game and the 15R shortened non-variable big hit game, the opening / closing door 42 is opened only once in each round game, as in the above-described 15R probability variable big hit game, and the entire number of the big hit games is opened and closed 15 times. Although the opening / closing door 42 repeats, the opening time of the opening / closing door 42 in the entire big hit game is shorter than that of the 15R probability change big hit game.

(About step-up jackpot games)
The step-up jackpot game is a 15-round jackpot game in which the prescribed number of rounds is set to “15”, and the upper limit number of winnings for each round game is set to “8”. In addition, in step-up jackpot games, regardless of the game state at the time of winning the jackpot lottery, after the jackpot game is finished, until the next jackpot game is generated, the probability change state and the winning rate improvement state are given after the jackpot game ends. It has come to be.

  In this step-up jackpot game, the round games of the first to eighth rounds and the round games of the tenth to fifteenth rounds are opened for a long time that continues to open the special prize opening 33 from the start to the end of the round game. The opening / closing door 42 is set to perform the operation. The ninth round game of the step-up jackpot game is set so that the opening / closing door 42 of the special prize-winning device 30 is opened a plurality of times (8 times in the embodiment). That is, the step-up jackpot game is an all-open round game in which the opening / closing door 42 performs a long-time opening operation in which a predetermined number of round games (eight times) from the first round game are opened from the start to the end of the round game. And the next round game is constituted by the first special round game, and the remaining number of round games (6R) after the first special round game are constituted by the fully open round game. Yes. Here, in the first special round game (9th round game), the number of short-time round games corresponding to the 9th to 15th rounds in the 15R shortened probability variable big hit game and the 15R shortened non-probable big hit game. (7 times) After opening and closing the door 42 for a short time, which is substantially the same opening time as the short round game, the door is opened for a long time to open until the end of the first special round game. 42 is set to be performed. That is, the step-up big hit game constitutes a composite open hit game in which the open / close door 42 performs the long-time opening operation and the short-time opening operation.

  Here, in the step-up jackpot game, “25 (seconds)” is set as the round game time of the first round game of the first to eighth rounds and the tenth to fifteenth rounds, and each round game The opening / closing door 42 is opened for a long time of "25 (seconds)" at the maximum. On the other hand, in the round game of the ninth round, the opening time of the opening / closing door 42 in the first opening to the seventh opening is set to “0.2 (seconds)”, respectively, and the opening time of the opening / closing door 42 in the eighth opening is set. It is set to “23.6 (seconds)”. Further, after the first opening to the seventh opening, “2.0 (seconds)” is set as the interval time in the round. As a result, the round game time of the ninth round of step-up jackpot game is “39 (seconds)” consisting of “(0.2 (seconds) +2.0 (seconds)) × 723.6 (seconds)”. Will be set to.

  Also, in the ninth round of the step-up jackpot game, the time from the first opening of the door 42 to the seventh closing ("13.4 (seconds)") is 15R shortened probability variable hit game and 15R shortened non-probable bonus hit. In the game, the same time as the opening / closing door 42 of the special winning device 30 is closed in the 15th round after the opening / closing door 42 of the special winning device 30 is opened in the ninth round. In the step-up jackpot game, “7.0 (seconds)” is set as the opening time, and “14.6 (seconds)” is set as the ending time. In addition, the interval time between rounds of these jackpot games is set to “2.0 (seconds)” except before the start of the final round, and “1.996 (seconds)” before the start of the final round. Yes. Therefore, the opening / closing operation of the open / close door 42 from the start of the step-up big hit game until the open / close door 42 is closed for the seventh time in the ninth round starts the 15R shortened probability variable hit game and the 15R shortened uncertain variable hit game. From the fifteenth round, the opening / closing operation of the opening / closing door 42 until the opening / closing door 42 of the special prize-winning device 30 is closed appears to be the same opening / closing operation.

(About 2R special probability variable big hit game and 2R normal probability variable big hit game)
The 2R special probability variable big hit game and the 2R normal probability variable big hit game are two round big hit games with the specified number of rounds set to “2”, and the upper limit number of winnings for each round game is set to “8”. Yes. And in the 2R special probability variable big win game, regardless of the game state at the time of winning the big hit lottery, after the big hit game is finished, until the next big hit game is generated, the positive change state and the winning rate improvement state after the big hit game is finished. It is to be granted. In addition, in the 2R normal probability variable big hit game, regardless of the game state at the time of winning the big hit lottery, the positive change state is given after the big hit game ends, while the winning rate improvement state is not given after the big hit game ends. .

  In each round game of 2R special probability variable big hit game and 2R normal probability variable big hit game, the opening and closing door 42 is set to perform a short-time opening operation that opens the special winning opening 33 continuously from the start to the end of the round game. ing. That is, all the round games of the 2R special probability variable big hit game and the 2R normal probability variable big hit game are constituted by a short round game in which the open / close door 42 performs a short time opening operation for opening from the start to the end of the round game. Therefore, in the 2R special probability variable big hit game and the 2R normal probability variable big hit game, the open / close door 42 is opened only once in each round game, and the open / close door 42 repeats the open / close operation twice in the whole big hit game. . In other words, the 2R special probability variable big hit game and the 2R normal probability variable big hit game constitute a short open per game that causes the open / close door 42 to perform only a short time opening operation, and the open / close door 42 in each big hit game looks and opens the same. The operation is to be performed.

  Here, in the 2R special probability variable big hit game and the 2R normal probability variable big hit game, “0.06 (seconds)” is set as the round game time of one round game. In these jackpot games, “0.06 (seconds)” is set as the opening time, and “0.05 (seconds)” is set as the ending time. Also, the interval time between rounds of these jackpot games is set to “1.5 (seconds)” except before the start of the final round. In other words, the opening time and round game time in the 2R special probability variable jackpot game and the 2R normal probability variable jackpot game are the opening time of the jump-up jackpot game, which will be described later, and the opening / closing door 42 of the first and second special winning devices 30 in the first round. In the 2R special probability variable big hit game and the 2R normal probability variable big hit game, the opening and closing door 42 is closed in the second round after the opening and closing door 42 is closed in the second round. The time (“1.62 (seconds)”) is the same as the time until the opening / closing door 42 of the special winning device 30 finishes the second opening in the first round of the jump-up jackpot game.

  Each round game time (0.2 (seconds)) in 2R special probability variable big hit game and 2R normal probability variable big hit game is the number of pachinko balls that will win the special prize device 30 in one round game. The time is set so as not to satisfy. That is, in the 2R special probability variable big hit game and the 2R normal probability variable big hit game, as in the round game after the ninth round of the 15R shortened probability variable big hit game and the 15R shortened non-probable big hit game described above, the upper limit number of winnings in the round game time The “8 balls” pachinko ball that will be won will be released for a short time, which is practically impossible, and almost no winning ball will be generated in the 2R special probability variable big hit game and 2R normal probability variable big hit game. do not do.

(About jump-up jackpot game)
The jump-up jackpot game is a 15-round jackpot game in which the specified number of rounds is set to “15”, and the upper limit number of winnings in each round game is set to “8”. In addition, in the jump-up jackpot game, regardless of the game state at the time of winning the jackpot lottery, after the jackpot game is finished, until the next jackpot game is generated, a probabilistic state and a winning rate improvement state are given after the jackpot game ends. It has come to be.

  In this jump-up jackpot game, the opening / closing door 42 of the special prize device 30 is opened a plurality of times (three times in the embodiment) in the first round game, and the round game starts in the second to fifteenth round games. The opening / closing door 42 is set to perform a long-time opening operation to open the special winning opening 33 continuously from the end to the end. That is, in the jump-up jackpot game, the first round game is composed of the second special round game, and the remaining number of round games (for 14R) after the second special round game is composed of the fully open round game. ing. Here, in the second special round game (the first round game), the short-time release that is substantially the same as the short-time release operation in the 2R special probability variable big hit game, the 2R normal probability variable big hit game, and the small hit game. Opening / closing door is operated for a long time to open until the end of the second special round game after the opening / closing door 42 is operated by the number of times of opening / closing in 2R special probability variable big hit game, 2R normal probability variable big hit game, and small hit game. 42 is set to be able to go. That is, the jump-up big hit game constitutes a composite open hit game in which the opening / closing door 42 performs the long-time opening operation and the short-time opening operation.

  Here, in the first round game of the jump-up jackpot game, the opening time of the opening / closing door 42 in the first opening to the second opening is set to “0.06 (seconds)”, respectively, and the third opening door The opening time of 42 is set to “24.88 (seconds)”. In addition, “1.5 (seconds)” is set as the interval time in the round between the first opening and the second opening, and the interval time in the round is set between the second opening and the third opening. “1.5 (seconds)” is set. As a result, the round game time of the first round of the jump-up jackpot game is “0.06 (seconds) +1.5 (seconds) +0.06 (seconds) +1.5 (seconds) +24.88 (seconds). "28.0 (seconds)". Then, “25 (seconds)” is set as the round game time of one round game after the second round in the jump-up jackpot game, and the opening / closing door 42 is set to “25 (seconds) in each round game. ) "For a long time.

  In the first round of the jump-up jackpot game, the time from the first opening of the door 42 to the second closing (“1.62 (seconds)”) is the 2R special probability variable big hit game and the 2R normal probability variable big hit. In the game, it is the same time as the opening and closing door 42 is closed in the second round after the opening and closing door 42 is opened in the second round. In the step-up jackpot game, “0.02 (seconds)” is set as the opening time, and “14.6 (seconds)” is set as the ending time. In addition, the interval time between rounds of these jackpot games is set to “2.0 (seconds)” except before the start of the final round, and “1.996 (seconds)” before the start of the final round. Yes. Therefore, the opening / closing operation of the door 42 from the start of the jump-up jackpot game until the door 42 is closed for the second time in the second round is performed after the 2R special probability variable big hit game and the 2R normal probability variable big hit game start. The opening / closing operation of the opening / closing door 42 until the opening / closing door 42 of the special prize-winning device 30 is closed in the second round appears to perform the same opening / closing operation.

(About small hit games)
Next, the small hit game given by the pachinko gaming machine 10 of the embodiment will be described. The small hit game is set so that the opening / closing door 42 performs a short-time opening operation a plurality of times (in the embodiment, twice). That is, the small hit game constitutes a second hit game in which the opening / closing door 42 performs an opening operation including a short-time opening operation. In the small hit game, the game state after the end of the small hit game is continued with the game state at the time of winning the small hit lottery. In other words, in the small hit game, if the probability variation state is given at the time of winning the small hit lottery, the probability variation state is continuously given even after the small hit game is finished, while if the probability variation state is not granted, after the small hit game is finished. Does not give a probable state. In addition, in the small win game, if the winning rate improvement state is given at the time of winning the small hit lottery, the winning rate improvement state must be continuously given after the end of the small hit game, while the winning rate improvement state must be given. For example, the winning percentage improvement state is not given even after the small hit game ends.

  In the small hit game, the opening time of the first opening and the second opening is set to “0.06 (seconds)”, and the interval time between the first opening and the second opening is “1. 5 (seconds) "is set. That is, in one small hit game, it is set to be “1.62 (seconds)” consisting of “0.06 (seconds) +1.5 (seconds) +0.06 (seconds)”. Become. For this reason, the time until the opening / closing door 42 is closed for the second time after the start of the small hit game is the special winning device in the first round of the 2R probability variable big hit game (2R special probability variable big hit game and 2R normal probability variable big hit game). 30 is the same as the time until the special winning device 30 is closed in the second round after the opening / closing door 42 is opened. Furthermore, the time until the opening / closing door 42 is closed for the second time after the start of the small hit game is the second opening after the special winning device 30 is opened for the first time in the first round of the jump-up big hit game. Is the same as the time until the end. That is, in the small hit game, the opening / closing door 42 is subjected to a short opening operation that is substantially impossible to win a pachinko ball within the opening time (0.12 (second)) of the opening / closing door 42 per time. The winning ball in the small hit game is hardly generated. The opening / closing operation of the opening / closing door 42 in the small hit game is performed in the second round after the opening / closing operation of the opening / closing door 42 in the 2R special probability variable big hit game and the 2R normal probability variable big hit game or the jump-up big hit game starts. The opening / closing operation of the opening / closing door 42 until it is closed for the second time is the same opening / closing operation.

(Regarding the control configuration of the pachinko machine 10)
Next, the control configuration of the pachinko machine 10 will be described. The control device 60 provided in the pachinko machine 10 includes a CPU 60a that executes control processing, an R0M 60b that stores a control program executed by the CPU 60a, various random values that the CPU 60a reads, and various information that accompanies the control processing. RAM 60c etc. which can memorize | store temporarily are provided. Various sensors such as the starting winning ball detection sensor 29, the special winning ball detection sensor 39, and the passing ball detection sensor 49 are connected to the CPU 60a. In addition, the CPU 60a is connected to each display such as the symbol display device 18, the special figure display 50, the special figure hold display 51, 52, the general figure display 53, the general figure hold display 54, etc. Based on the control process executed by the CPU 60a triggered by the detection of the sensors 29, 39, and 49, the display controls of the respective indicators 50, 51, 52, and 53 are executed, and the display control of the symbol display device 18 is executed. In addition, drive control of solenoids 27 and 40 provided in the start winning device 26 and the special winning device 30 is performed. Further, the CPU 60a updates the values of various random numbers such as a hit determination random number every predetermined cycle (for example, 2 milliseconds), stores the updated values in the setting area of the RAM 60c, and rewrites the values before the update. Yes.

  Here, the R0M 60b has a game effect (the content of the effect on the symbol display device 18) that is performed between when the special figure starts to fluctuate and until it is finally stopped and displayed (until the special figure fluctuating display ends). Etc.) are stored as a plurality of types of variation patterns. That is to say, the effect content and effect time (the change time of the special figure or decoration) from the start of the special figure to the final stop display is specified by the fluctuation pattern. Accordingly, on the special figure display 50, the fluctuation stops when the fluctuation time determined in the fluctuation pattern elapses after the fluctuation of the special figure starts, and the big hit symbol, the small hit symbol or the off symbol is fixedly stopped and displayed. . Then, a symbol variation effect is performed with the effect content specified by the variation pattern in the symbol display device 18, and the variation of the decorative drawing is stopped when the variation time determined in the variation pattern has elapsed, and the special symbol display 50 is stopped. The symbol combination of the decorative drawing corresponding to the displayed special drawing is displayed in a fixed stop state.

  Among a plurality of types of variation patterns in this embodiment, 15R probability variation jackpot game, 15R probability variation concealment jackpot game, 15R non-probability variation jackpot game, 15R shortened probability variation jackpot game, 15R shortened uncertain variation jackpot game and step-up jackpot game are determined. There is a variation pattern for a big hit effect that is selected when it is made. Among the plurality of types of variation patterns, there are variation patterns for concealment effects that are selected when a jump-up big hit game, a 2R special probability variable big hit game, a 2R normal probability variable big hit game, and a small hit game are determined. Further, among the plurality of types of variation patterns, there is a variation pattern for a loss effect selected when the big hit lottery and the small hit lottery are not won. In addition, the variation pattern for the offending effect includes a variation pattern for the outlier reach effect including the reach effect and a variation pattern for the outlier normal effect not including the reach effect. Note that there are multiple types of variation patterns for the big hit effect, the concealment effect, the outlier reach production and the outlier normal production. For example, when a 15R special probability variable big hit game is determined, a plurality of types are provided. One variation pattern for the jackpot effect is determined from the variation patterns for the jackpot effect.

  The R0M 60b stores a plurality of types of hit effect patterns indicating patterns serving as a base for game effects (win effects) performed on the symbol display device 18 during a hit game (between big hit games or small hit games). ing. When a 15R probability variation big hit game, a 15R probability variation concealment big hit game, and a 15R non-probability big hit game are determined, one hit effect pattern is selected from a plurality of types of common hit effect patterns that can be selected in the hit game. It is determined. Therefore, it cannot be determined from the content of the winning effect performed on the symbol display device 18 during the winning game, which winning game of 15R probability variation big hit game, 15R probability variation secret big hit game, and 15R non-probability large hit game is given. It has become.

  When a 15R shortened probability variation big hit game, a 15R shortened uncertain variable big hit game, and a step-up big hit game are determined, one hit effect pattern is selected from a plurality of types of common hit effect patterns that can be selected in the hit game. Is determined. That is, when a 15R shortened probability variation big hit game, a 15R shortened uncertain variable big hit game, and a step-up big hit game are determined, a hit effect with basically the same contents of the effect is performed. In this hit effect pattern, when the step-up big hit game is determined, the opening and closing door 42 is opened for the eighth time (that is, opened for a long time) in the ninth round from the start of the hit game. The specific display indicating that the game is a step-up jackpot game is set to be displayed. By displaying this specific display, the player can grasp that the game is a step-up jackpot game, while the specific display is displayed. When is not displayed, the player knows that it is a big hit game other than the step-up big hit game (that is, a 15R shortened probability variable big hit game, a 15R shortened non-probable big hit game). That is, in the jackpot game, which hit game of 15R shortened probability variable hit game, 15R shortened non-probable bonus game or step-up jackpot game was given from the contents of the hit effect (common effect) performed on the symbol display device 18? Cannot be discriminated. When the step-up jackpot game is determined, the winning effect corresponding to the round games of the 10th to 15th rounds is continuously executed. Here, when the step-up jackpot game is determined, the time when the opening / closing door 42 opens for the eighth time (that is, the opening for a long time) in the ninth round is the opening of the opening / closing door 42 and display of a specific display. This includes not only the case where the opening and closing doors 42 are opened simultaneously, but also the case where the opening / closing door 42 is shifted forward and backward in a time that the player cannot perceive the shift in the display timing of the specific display.

  Here, as the common effect in the winning game performed when the 15R shortened probability variation big hit game, the 15R shortened non-probable big hit game, and the step-up big hit game are determined, the completely same production contents may be used. It may be an effect suggesting that the jackpot game is a step-up jackpot game (or not a step-up jackpot game) by variously developing a story along with (the progress of the hit game). In this case, the expectation that the jackpot game is a step-up jackpot game may be changed by story development. The story developed in the common effect may have a continuous story flow, or may be a fight effect with characters A and B. The specific display indicating the step-up jackpot game is an explicit display such as “step-up jackpot game confirmed” or an indirect display such as a specific result display of the developed performance (for example, victory of character A). Is possible.

  In the embodiment, when a jump-up big hit game, 2R special probability variable big hit game, 2R normal probability variable big hit game, and small hit game are determined, a plurality of types of common hit performance patterns that can be selected in these hit games are selected. One hit production pattern is determined from the inside. That is, when a jump-up big hit game, a 2R special probability variable big hit game, a 2R normal probability variable big hit game, and a small hit game are determined, a hit effect with basically the same effect contents is performed. In this hit effect pattern, when a jump-up jackpot game is determined, the time from the start of the hit game to the time when the open / close door 42 is opened for the third time (that is, opened for a long time) in the first round. The second specific display indicating that the game is a jump-up jackpot game is set to be displayed. By displaying the second specific display, the player knows that the game is a jump-up jackpot game. On the other hand, if the specific display is not displayed, the player knows that the hit game of the jump-up jackpot game (that is, 2R special probability variable big hit game, 2R normal probability variable big hit game or small hit game). It has become. That is, in the winning game, from the contents of the winning effects (common effects) performed on the symbol display device 18, any winning game of jump-up big hit game, 2R special probability variable big hit game, 2R normal probability variable big hit game and small hit game is determined. It is impossible to determine whether it has been granted. When the jump-up big hit game is determined, the hit effect corresponding to the round games of the second round to the fifteenth round is continuously executed. Here, when the jump-up jackpot game is determined, the time when the opening / closing door 42 opens for the third time (that is, the opening for a long time) in the first round is the opening of the opening / closing door 42 and the display of a specific display. This includes not only the case where the opening and closing doors 42 are opened simultaneously, but also the case where the opening / closing door 42 is shifted forward and backward in a time that the player cannot perceive the shift in the display timing of the specific display.

  Here, as the common effect in the hit game when the jump-up jackpot game, the 2R special probability variable big hit game, the 2R normal probability variable big hit game and the small hit game are determined, the completely same effect contents may be used. Even if the performance suggests that the jackpot game is a jump-up jackpot game (or is not a jump-up jackpot game), as the story develops variously as the stage progresses (progress of hit game) Good. In this case, the expectation that the jackpot game is a jump-up jackpot game may be changed by story development. The story developed in the common effect may have a continuous story flow, or may be a battle effect with characters A and B. Further, the specific display indicating the jump-up jackpot game is an explicit display such as “jump-up jackpot game confirmed” or an indirect display such as a specific result display of the developed performance (for example, victory of character A). Is possible.

  The R0M60b stores a jackpot determination value. The big hit determination value is a determination value used in an internal lottery to determine whether or not to generate a big hit, and is determined from numerical values (a total of 1439 integers from 0 to 1438) that the random number for winning determination can take. The number of jackpot determination values differs depending on whether or not the probability variation state is given. The number of jackpot determination values in the probability variation state (33 in the embodiment) is the jackpot determination value in the normal state. More than the number (four in the embodiment) is set. Note that the jackpot determination value used in the jackpot determination based on the first special figure start pending storage number is the same as the jackpot determination value used in the jackpot determination based on the second special figure start pending storage number. .

  R0M60b stores a small hit determination value. The small hit determination value is a determination value used in the internal lottery to determine whether or not the small hit is, and is determined from numerical values (all 1439 integers from 0 to 1438) that the random number for hit determination can take. Further, a predetermined number (9 in the embodiment) of the small hit determination value is set. Note that the random number for hit determination uses the random number used in the big hit determination as it is. Further, the number of small hit determination values does not differ depending on whether or not a probability variation state is given and whether or not a winning rate improvement state is given (the same value is determined).

  The RAM 60c stores a hit determination random number used in the internal lottery for the big hit determination and the small hit determination. The value of the random number for hit determination stored in the RAM 60c is updated every predetermined period (for example, 2 milliseconds), and the updated value is stored in the setting area of the RAM 60c to rewrite the value before the update. Then, when the pachinko ball wins the upper and lower start winning holes 26a, 26b, the CPU 60a acquires the random number for hit determination. Then, it is determined whether or not the value of the random number for hit determination acquired by the CPU 30a matches the predetermined jackpot determination value, and the result of the special figure fluctuation display (symbol fluctuation effect) based on the random number for hit determination Is set to determine whether or not a big hit is made. If the determination result of the big hit determination is negative, it is determined whether or not the acquired value of the random number for hit determination matches the predetermined small hit determination value, and a special characteristic based on the random number for hit determination is determined. It is set to make a small hit determination as to whether or not the result of the figure variation display (design variation effect) is a small hit. That is, the CPU 30a has functions as random number acquisition means and hit determination means (big hit determination means and small hit determination means).

  The RAM 60c stores special figure distribution random numbers used when determining the type of special figure that becomes a big hit symbol. Each special figure is assigned a predetermined number (one in the embodiment) of this special figure distribution random number, and the CPU 60a determines when the big hit or the small hit is determined (if the big hit determination becomes affirmative or the small hit) If the determination is affirmative), the big hit symbol or the small hit symbol is determined based on the acquired special figure distribution random number. This special distribution random number is determined by the CPU 60a at predetermined intervals (every 4 ms) so that numerical values within a predetermined numerical range (in the embodiment, all 50 integers from “0” to “49”) can be taken. ) Is updated by adding 1 to the numerical value. Then, the CPU 60a stores the updated value in the RAM 60c as the value of the special figure distribution random number, and sequentially updates the value of the special figure distribution random number by rewriting the value of the special figure distribution random number already stored. It is like that. In the embodiment, the special figure distribution random numbers are acquired when the pachinko balls win the upper and lower start winning openings 26a and 26b.

  Further, the RAM 60c stores small hit symbol distribution random numbers used when determining the type of special symbol as the small hit symbol. In each special figure, this small hit symbol distribution random number is distributed by a predetermined number (one in the embodiment), and the CPU 60a determines when a small hit is determined (when the small hit determination is affirmative). A small hit symbol is determined based on the acquired small hit symbol distribution random number. The small hit symbol distribution random number is determined by the CPU 60a at predetermined intervals (4 ms) so that numerical values within a predetermined numerical value range (in the embodiment, all ten integers “0” to “10”) can be obtained. Each time) is incremented by one and updated. Then, the CPU 60a stores the updated value in the RAM 60c as the value of the small hit symbol distribution random number, and rewrites the value of the small hit symbol distribution random number already stored, thereby changing the value of the small hit symbol distribution random number. It is designed to update sequentially. In the embodiment, the small hit symbol distribution random numbers are acquired when the pachinko balls win the upper and lower start winning holes 26a and 26b.

  Here, the value of the special figure distribution random number is appropriately distributed for each type of jackpot game, and when the big hit determination is affirmative, the value of the special figure distribution random number is determined, so that the big hit The types of games are also determined. That is, when the special figure variation display results in a big hit, the type of the big hit game is specified according to the determined big hit symbol (special figure), and the special figure as the big hit symbol is determined and specified. A big hit game is given. Further, in accordance with the determined jackpot symbol, it is determined whether or not to give a probability change state and a winning rate improvement state in the game after the jackpot game, and to determine a period for giving the probability changing state and the winning rate improvement state. It has become. In addition, when determining the small hit (when the big hit determination is negative and the small hit determination is affirmative), a special figure is determined from the ten types of small hit symbols, A small hit game is given after the is displayed. At the time of determination of outage (when the big hit judgment and the small hit judgment are negative), a special figure is determined from one type of outlier symbol, and the special figure as the outlier symbol is confirmed and displayed. Then, the special figure fluctuation display is completed and the next special figure fluctuation display is performed. At the time of determining the small hit, the probability change state and the winning rate improvement state in the game after the small hit game maintain the state before the small hit game is performed.

  R0M60b stores a normal hit determination value. The normal hit determination value is a determination value used in the internal lottery for determining whether or not the normal hit is made, and is determined from numerical values (all 107 different integers from 0 to 106) that the normal hit determination random number can take. Note that the number of normal winning judgment values differs depending on whether or not the winning rate improvement state is given, and the number of normal winning judgment values when the winning rate improvement state is given (in the embodiment, 106 Is set to be larger than the number of normal hit determination values in the normal state (two in the embodiment). The RAM 30C stores a normal hit determination random number used for the normal hit determination. In the embodiment, the normal hit determination random number is acquired when the pachinko ball passes through the ball passage gate 47.

  In other words, the hit game determining means (big hit determining means and small hit determining means) for determining the type of hit game to be given out from a plurality of types of hit games, and the determined type of hit games after the end of the special figure change display (symbol change) The CPU 30a has a function as a hit game giving means to be given after the presentation is finished). The CPU 30a functions as a probability change determination means for determining whether or not to give a probability change state in which the probability of occurrence of a big hit (the probability that the determination result by the big hit determination means becomes affirmative) is higher than usual. And, it is configured to function as a probability change giving means for giving a probability change state after the end of the big hit game. Here, the CPU 30a determines whether or not to give a probability change state only when a big hit occurs (when the determination result of the big hit determination means is affirmative) and 2R special probability variable big hit game and 2R normal probability variable big hit game. Is given, it is determined that the probability variation state is given. Further, the CPU 30a gives a winning rate improvement state in which the probability that a pachinko ball will win the lower start winning opening 27b is high when a big hit occurs (when the result of the big hit determination means is affirmative). It functions as a winning rate improvement state determination means that determines whether or not to win, and when giving a winning rate improvement state, a special number variation display (symbol variation effect) is executed a predetermined number of times after the end of the jackpot game Until the next jackpot game is awarded or the next jackpot game is awarded as a winning rate improvement state grant period determining means for determining the winning rate improvement state, and the jackpot It also functions as a winning rate improvement state giving means for giving a winning rate improvement state only during a period of giving a winning rate improvement state determined after the game ends.

  Next, various processes executed by the CPU 60a of the control device 60 based on the control program will be specifically described.

(About special map processing)
In the special figure input process, as shown in FIG. 13, the CPU 60a determines whether or not a pachinko ball has won a winning winning opening 26a on the upper side of the starting winning device 26 (step S11). That is, in step S11, the CPU 60a determines whether or not a detection signal output when the start winning ball detection sensor 29 corresponding to the upper start winning port 26a detects a pachinko ball has been input. And when the determination result of step S11 is negative, it transfers to step S15. If the determination result of step S11 is affirmative, the CPU 60a determines whether or not the first special figure start pending storage number stored in the RAM 60c is less than the upper limit number of 4 (step S12). If the determination result of step S12 is negative (that is, the first special figure start hold storage number is 4), the CPU 60a proceeds to step S15.

  If the determination result in step S12 is affirmative (first special figure start hold memory number <4), the first special figure start hold memory number is incremented by 1, and the first special figure start hold memory number stored in the RAM 60c is determined. Rewriting is performed (step S13). Subsequently, the CPU 60a reads out the value of random number for hit determination, the value of random number for special figure distribution, and the value of random number for small pattern assignment from the RAM 60c, and sets the value of the random number as the first special figure start pending storage number. A predetermined storage area of the associated RAM 60c is set (step S14). Thereby, the process proceeds to step S15.

  Further, in step S15, the CPU 60a determines whether or not the pachinko ball has won the start winning opening 26b on the lower side of the start winning device 26. That is, in step S15, the CPU 60a determines whether or not a detection signal output when the start winning ball detection sensor 29 corresponding to the lower start winning port 26b detects a pachinko ball has been input. If the determination result in step S15 is negative, the special figure input process is terminated. If the determination result of step S15 is affirmative, the CPU 60a determines whether or not the second special figure start pending storage number stored in the RAM 60c is less than the upper limit number of 4 (step S16). If the determination result of step S16 is negative (that is, the second special figure start hold storage number is 4), the CPU 60a ends the special figure input process.

  If the determination result in step S16 is affirmative (second special figure start reserved memory number <4), the second special figure start reserved memory number is incremented by 1, and the second special figure start reserved memory number stored in the RAM 60c is determined. Rewriting is performed (step S13). Subsequently, the CPU 60a reads the random number value for hit determination, the value of the special figure distribution random number, and the value of the small hit symbol distribution random number from the RAM 60c, and uses the random number value as the second special figure start pending storage number. The predetermined storage area of the associated RAM 60c is set (step S17). Thereby, the special figure input process is completed.

(Special drawing start process)
Next, the special figure start process will be described with reference to FIG. In the special figure starting process, the CPU 60a is displaying the symbols (special illustrations and decorations) in the special symbol display 50 and the symbol display device 18, or is in a winning game (big hit game or small hit game). It is determined whether or not (step S201). If the determination result of step S201 is affirmative, the CPU 60a ends the special figure start process. On the other hand, if the determination result in step S201 is negative, the second special figure start reserved memory number is read (step S202), and it is determined whether or not the second special figure start reserved memory number is greater than "0". (Step S203). When the determination result of step S203 is negative (when the second special figure start hold storage number = 0), the CPU 60a proceeds to the process of step S206. If the determination result in step S203 is affirmative (second special figure start hold memory number> 0), the second special figure start hold memory number is decremented by 1 (step S204), and the second special figure start hold memory number is subtracted. The CPU 60a acquires the values of the hit determination random number, special figure distribution random number, and small hit symbol distribution random number stored in a predetermined storage area of the RAM 60c associated with the figure start pending storage number (step S205). ) Next, a hit determination process is executed.

  If the determination result of step S203 is negative, the first special figure start hold memory number is read (step S206), and it is determined whether or not the first special figure start hold memory number is greater than "0" (step S206). S207). If the determination result in step S207 is affirmative (the first special figure start hold memory number> 0), the first special figure start hold memory number is subtracted by 1 (step S208), and the first special figure start hold memory number is subtracted. The CPU 60a acquires the values of the hit determination random number, special figure distribution random number, and small hit symbol distribution random number stored in a predetermined storage area of the RAM 60c associated with the figure start pending storage number (step S209). ) Next, a hit determination process is executed. On the other hand, when the determination result of step S207 is negative (when the first special figure start hold storage number = 0), the CPU 60a determines whether or not the demonstration effect is being executed (step S210). If the result is negative, a demonstration designation command is output and the special figure start process is terminated (step S211). If the determination result in step S24 is affirmative (if the demonstration effect is being executed), the CPU 60a ends the special figure start process.

(About winning judgment processing)
In the hit determination process, as shown in FIG. 15, a big hit determination (big hit lottery) is performed for determining whether or not the value of the random number for hit determination acquired by the CPU 60a matches the big hit determination value stored in the R0M 60b. (Step S31). As described above, the probability that the determination result of the big hit determination becomes positive in the normal state (low probability) (the big hit probability) is set to 4/1439, and the probability change state (high probability) ) Is determined to be 33/1439. If the determination result of the big hit determination means 62 in step S31 is affirmative (if a big hit occurs), “1” is set to the big hit flag indicating that the big hit is changed (step S32). . Then, the CPU 60a determines a final stop symbol (special symbol) to be confirmed and stopped on the special symbol display 50 from the jackpot symbols based on the acquired special symbol distribution random number value (step S33). Next, the CPU 60a identifies the type of jackpot game from the determined final stop symbol, and determines a variation pattern corresponding to the identified jackpot game (step S34). Based on the determined variation pattern and the final stop symbol, the CPU 60a executes various processes related to the special symbol variation display on the special symbol display 50 and the symbol variation effect on the symbol display device 18 (step S35).

  On the other hand, if the determination result of the big hit determination in step S31 is negative (if it is not a big hit), the CPU 60a determines whether the acquired value of the random number for hit determination matches the small hit determination value stored in the R0M 60b. It is determined whether or not a small hit determination (small hit lottery) is performed (step S36). When the determination result in step S36 is affirmative (in the case of small hit), the CPU 60a sets “1” in the small hit flag indicating that the fluctuation is in the small hit (step S37). Then, the CPU 60a determines a final stop symbol (special symbol) to be confirmed and stopped by the special symbol display 50 from the small symbol symbols according to the special symbol based on the acquired small hit symbol distribution random number (step S38). . Thereafter, the CPU 60a determines a variation pattern for concealment effect corresponding to the small hit game (step S39). The CPU 60a that has determined the variation pattern and the final stop symbol moves to the process of step S35, and similarly to the above, the special symbol variation display and symbol display on the special symbol display 50 based on the determined variation pattern and final stop symbol. The CPU 60a executes various processes related to the symbol variation effect in the device 18.

  On the other hand, if the determination result of the small hit determination in step S36 is negative (if it is not a small hit), the CPU 60a performs a reach determination that determines whether or not to execute the reach effect (step S40). In the embodiment, the CPU 60a determines whether or not the reach determination random number acquired from the RAM 60c during the process of step S40 matches the reach determination value. The reach determination value is a determination value used in an internal lottery for determining whether or not a reach effect is to be performed, and is determined from values that can be taken by random numbers for reach determination (a total of 241 integers from 0 to 240). Yes. If the determination result in step S40 is affirmative (when a reach effect is to be performed), the CPU 60a determines the outlier symbol as the final stop symbol (special symbol) that is confirmed and stopped on the special symbol indicator 50. (Step S41). Next, the CPU 60a determines a variation pattern for an outlier reach effect (step S42). Then, the CPU 60a that has determined the variation pattern and the final stop symbol moves to the process of step S35, and similarly to the above, the special diagram variation display on the special symbol display 50 and the special symbol indicator 50 based on the determined variation pattern and the final stop symbol. The CPU 60a executes various processes related to the symbol variation effect on the symbol display device 18.

  On the other hand, when the determination result in step S40 is negative (when the reach is not performed), the CPU 60a determines the outlier symbol as the final stop symbol (special symbol) displayed on the special symbol display 50 in a fixed stop manner. (Step S43). Next, the CPU 60a determines a variation pattern for the off-normal effect (step S44). Then, the CPU 60a that has determined the variation pattern and the final stop symbol moves to the process of step S35, and similarly to the above, the special diagram variation display on the special symbol display 50 and the special symbol indicator 50 based on the determined variation pattern and the final stop symbol. The CPU 60a executes various processes related to the symbol variation effect on the symbol display device 18.

(About the case where a jackpot game is awarded)
Then, when the hit determination means 66 determines the big hit (when “1” is set in the big hit flag), the CPU 60a determines the type of big hit determined after the special symbol variation display (symbol variation effect) ends. Start controlling the game. Hereinafter, the contents of control performed by the control device 60 when a jackpot game is awarded will be described for each jackpot game.

(When 15R probability variation, 15R probability variation concealment and 15R non-probability large hit game are awarded)
When the CPU 60a determines any of 15R probability variation jackpot game, probability variation concealment jackpot game, and 15R non-probability variation jackpot game, the CPU 60a completes a predetermined opening effect time when the special symbol variation display (symbol variation effect) ends. After the elapse of (7 seconds), the first round game is started, the round game time (max 25 seconds) is started, and the opening / closing door 42 of the special prize winning device 30 is opened for a long time. In the first round game, the opening / closing door 42 is closed on condition that the end condition (elapse of the round game time or a predetermined number of pachinko balls is won) is satisfied, so that the round game (all open rounds) (Game) ends.

  When the round game of the first round is finished, the round game of the second round (all open round games) is started after the elapse of a predetermined interval time (2.0 seconds), The measurement of the round game time (max 25 seconds) is started, and the opening / closing door 42 of the special winning device 30 is opened for a long time. In the second round game, the opening / closing door 42 is closed on condition that the end condition (elapse of round game time or winning of a predetermined number of pachinko balls) is satisfied. Ends. Thereafter, similarly, in the round game of the third round to the fifteenth round, the door 42 is controlled to be opened for a long time. Run and the jackpot game ends.

  When the 15R probability variation big hit game is awarded, the CPU 60a sets “1” in the probability variation flag, and “until next time” the probability variation state imparted number of times indicating the number of remaining symbol variation effects to which the probability variation state is imparted. Set the value indicating. In the embodiment, “10000 times” is set as the number of times the probability variation state is imparted, and the probability variation state is substantially imparted until the next time. When “1” is set in the probability variation flag, it indicates that the probability variation state is assigned, and when “0” is set, it indicates that the probability variation state is not imparted. ing. In addition, when a 15R probability variable big hit game is awarded, the CPU 60a sets “1” to the action flag, and “until next time” is set to the number of actions indicating the remaining number of symbol variation effects to which the winning rate improvement state is given. Set the value indicating. In the embodiment, “10000 times” is set as the number of times the winning rate improvement state is given, and the winning rate improvement state is substantially given until the next time. When the operation flag is set to “1”, it indicates that the winning rate improvement state is given, and when “0” is set, the winning rate improvement state is not given. Is shown. The probability variation state grant count and the winning rate improvement state grant count are decremented by 1 each time a special symbol variation display (symbol variation effect) is executed, and each value becomes “0” or a big hit game is granted. Then, “0” is set in the probability variation flag and the operation flag.

  When the 15R probability variation concealment jackpot game is awarded, the main CPU 60a sets “1” to the probability variation flag, and the main CPU 60a (winning rate improvement state giving means) sets “1” to the operation flag. A value indicating “until next time” is set as the number of times the probability variation state is given. Further, the main CPU 60a sets 50 as the number of operations. Then, the CPU 60a sets “0” in the big hit flag. On the other hand, when the 15R non-probability big hit game is awarded, the main CPU 60a sets “0” to the probability change flag, and the main CPU 60a (winning rate improvement state giving means) sets “1” to the operation flag. Then, a value indicating “until next time” is set in the probability variation state grant count. Further, the main CPU 60a sets 50 as the number of operations. Then, the CPU 60a sets “0” in the big hit flag.

(When 15R shortened probability variation big hit game or 15R shortened non-probable big hit game is awarded)
Next, control when the CPU 60a determines to give a 15R shortened probability variable big hit game or a 15R shortened non-probable big hit game will be described. In the round game of the first round to the eighth round in the 15R shortened probability variable big hit game or the 15R shortened non-variable big hit game, the first round corresponding to the 15R probability variable big hit game, the 15R positive variable secret big hit game, and the 15R non-probable big hit game described above ~ The opening / closing control is executed so that the opening / closing door 42 performs the same opening / closing operation as the eighth round game.

  When the round game of the 8th round is completed, measurement of a predetermined round game time (max 0.2 seconds) is started with the start of the 9th round, and the opening / closing door 42 of the special prize winning device 30 is opened for a short time. When the end condition is satisfied in the ninth round game, the door 42 is closed and the ninth round game is ended. When the round game of the 9th round is completed, after a predetermined interval time (2.0 seconds) has elapsed, measurement of the round game time (max 0.2 seconds) is started and a special prize is awarded in the same manner as the 9th round. The opening / closing door 42 of the device 30 is opened for a short time, and when the end condition is satisfied in the 10th round game, the opening / closing door 42 is closed and the 10th round game is ended. Thereafter, similarly, in the 11th to 15th round games, the door 42 is controlled to open for a short time, and when the 15th round game ends, the interval time between rounds (1.996). Seconds), the ending effect of the ending time (14.6 seconds) is executed, and the jackpot game is ended. That is, the round games of the 1st to 8th rounds in the 15R shortened probability variable big hit game and the 15R shortened non-probable big hit game are “all open round games”, and the round games in the 9th to 15th rounds are “short time”. "Round game".

  In addition, when the 15R shortened probability variation jackpot game has been awarded, the CPU 60a sets “1” to the probability variation flag indicating that the probability variation state is to be imparted after the jackpot game ends, and also imparts a winning rate improvement state. "1" is set in the operation flag indicating that. Further, when the 15R shortened probability variation big hit game is awarded, the CPU 60a sets values indicating “until next time” to the probability variation state grant count and the operation count. Then, the CPU 60a sets “0” in the big hit flag.

  On the other hand, if the 15R shortened non-probability big hit game is given, the CPU 60a sets “0” to the probability change flag after the big hit game ends, and sets an operation flag indicating that the winning rate improvement state is given. Set “1”. When the 15R shortened uncertain large hit game is awarded, the CPU 60a sets 50 times as the number of operations. Then, the CPU 60a sets “0” in the big hit flag.

(When a step-up jackpot game is awarded)
When the CPU 60a determines a step-up jackpot game, in the round games of the first to eighth rounds and the tenth to fifteenth rounds, the 15R probability variable jackpot game, the 15R probability variable secret jackpot game, and the 15R non-probability jackpot game While the same control as the round game of the corresponding round of the game is executed, the control of the 9th round game is different from that of the 9th round such as the 15R probability variable big hit game.

  Specifically, when the round game of the eighth round is finished, in the ninth round, the CPU 60a requires that the maximum number of pachinko balls for winning is not won during the round game time (max 39 seconds). In addition, the open / close door 42 of the special winning device 30 is opened and closed a maximum of eight times. The CPU 60a first opens the opening / closing door 42 for the first short-time opening operation, and the predetermined opening time (0.2 seconds) has elapsed since the opening / closing door 42 of the special winning device 30 is opened (first opening). At that time, the open / close door 42 is closed. When a predetermined in-round interval time (2.0 seconds) has elapsed after the opening / closing door 42 is closed (first closing), the opening / closing door 42 is caused to perform a second short-time opening operation. The door 42 is closed when a predetermined opening time (0.2 seconds) has elapsed since the opening of the door (opening for the second time). Then, the CPU 60a performs the same opening / closing operation from the start of the ninth round until the opening / closing door 42 is opened and closed seven times.

  The CPU 60a causes the opening / closing door 42 to perform a long-time opening operation when the predetermined in-round interval time (2.0 seconds) has elapsed since the opening / closing door 42 was closed (seventh closing) (the eighth opening). Open), the door 42 is closed when a predetermined opening time (max 23.6 seconds) elapses after the door 42 is opened (the eighth opening). Then, a predetermined opening time (max 23.6 seconds) elapses after the eighth opening, or the number of winning pachinko balls from the start of the round game of the ninth round reaches the upper limit number (specified number) of winning. On the condition, the round game of the ninth round is finished. When the ninth round game is completed, the opening / closing door 42 is caused to perform a round game long-time opening operation of the tenth to fifteenth rounds after a predetermined interval time (2.0 seconds) between rounds. That is, in the step-up jackpot game, the first to eighth rounds and the tenth to fifteenth round games are “all open round games”, and the ninth round game is “first special round game”. "

  Then, the CPU 60a sets “1” to the probability variation flag and the operation flag after finishing the big hit game. Further, the CPU 60a sets a value indicating “until next time” to the probability variation state imparting count and the actuation count. Then, the CPU 60a sets “0” in the big hit flag.

(When 2R special probability variable big hit game and 2R normal probability variable big hit game are given)
Next, the control when the CPU 60a determines the 2R special probability variable big hit game and the 2R normal probability variable big hit game will be described. The opening / closing operation mode of the door 42 in the 2R special probability variable big hit game and the 2R normal probability variable big hit game is the same.

  When the special symbol variation display (symbol variation effect) ends, the CPU 60a starts the first round game after the elapse of a predetermined opening time (0.02 seconds), and the round game time (max 0.06 seconds). The measurement is started and the opening / closing door 42 is opened for a short time. Then, as the round game time elapses, the open / close door 42 is closed and the first round game is completed. When the round game of the first round is completed, the round game of the second round is started after the elapse of a predetermined interval time (1.5 seconds), and the round game time ( (max 0.06 seconds) is started, and the opening / closing door 42 of the special winning device 30 is opened for a short time. Then, as the round game time elapses, the open / close door 42 is closed and the second round game is completed. Then, when the round game of the second round is finished, the CPU 60a performs an ending effect of the ending time (0.5 seconds) after the interval time between rounds (1.5 seconds) has elapsed, ends the jackpot game, and the CPU 60a Sets “0” in the big hit flag. That is, all the round games of the first to second rounds in the 2R special probability variable big hit game and the 2R normal probability variable big hit game are “short-time round games”.

  Further, when the 2R special probability variable big hit game and the 2R normal probability variable big hit game are awarded, the CPU 60a sets “1” to the probability variable flag and sets a value indicating “until next time” to the probability variation state grant count. . When the 2R special probability variable big hit game is awarded, the CPU 60a sets “1” to the operation flag and sets a value indicating “until next time” to the number of operations. On the other hand, when the 2R normal probability variation big hit game is awarded, the CPU 60a sets “0” for the number of operations and “0” for the operation flag.

(When jump-up jackpot game is awarded)
When the CPU 60a determines a jump-up jackpot game, the first round game is controlled differently from the first round of the 15R probability variable jackpot game, the 15R probability variable secret jackpot game, and the 15R non-probability variable jackpot game. In the round game from the second round to the fifteenth round, the same control as the round games from the second round to the fifteenth round such as the 15R probability variable big hit game is executed.

  When the special symbol variation display (symbol variation effect) ends, the CPU 60a starts the round game for the first round after the opening time (0.02 seconds), and starts measuring the round game time (max 28 seconds). To do. The CPU 60a opens and closes the open / close door 42 of the special winning device 30 up to three times on condition that the upper limit number of pachinko balls have not won. In the first round game, the opening / closing door 42 is opened for a short time, and the opening / closing door 42 of the special prize device 30 is opened (first opening), and then a predetermined opening time (0.06 seconds) is reached. When the time has elapsed, the open / close door 42 is closed. When a predetermined in-round interval time (1.5 seconds) elapses after the opening / closing door 42 is closed (first closing), the opening / closing door 42 is caused to perform a second short-time opening operation. The door 42 is closed when a predetermined opening time (0.06 seconds) has elapsed since the opening of the door (opening for the second time).

  The CPU 30a causes the opening / closing door 42 to perform a long-time opening operation when a predetermined in-round interval time (2.0 seconds) has elapsed after closing the opening / closing door 42 (second closing) (third time). Open), a predetermined opening time (max 24.88 seconds) has elapsed since the opening / closing door 42 is opened (third opening), or the number of pachinko balls won since the start of the first round game is the upper limit of winning The game of the first round is ended on condition that the number (specified number) is reached. That is, in the embodiment, the first round game in the jump-up jackpot game is a “second special round game” as a long-time round in which the open / close door 42 is opened for a long time. When the round game of the first round is completed, the opening / closing door 42 is caused to perform a long-time opening operation of the round games of the second round to the fifteenth round after a predetermined interval time (2.0 seconds) between rounds. . That is, the round game of the first round in the jump-up jackpot game is the “second special round game”, and the round games of the second round to the fifteenth round are “all open round games”.

  After completing the big hit game, the CPU 60a sets “1” to the probability variation flag and the operation flag. Further, the CPU 60a sets a value indicating “until next time” to the probability variation state imparting count and the actuation count. Then, the CPU 60a sets “0” in the big hit flag.

(About the case where a small hit game is granted)
Then, when the small hit is determined (when “1” is set in the small hit flag), the CPU 60a starts the control of the small hit game after the end of the special figure change display (design change effect).

  When the special symbol variation display (symbol variation effect) ends, the CPU 60a starts measuring the opening time 0.06 seconds) and causes the opening / closing door 42 to perform a short opening operation. Then, the opening / closing door 42 is closed as the opening time elapses, and the first opening is completed, and after the predetermined interval time (1.5 seconds) has elapsed, the measurement of the opening time 0.06 seconds is similarly started. At the same time, the opening / closing door 42 is opened for a short time, and the opening / closing door 42 is closed as the opening time elapses, and the second opening is completed. Thereby, the small hit game ends, and the CPU 60a sets “0” in the small hit flag. In the case of a small hit game, since the game state at the time of winning a small hit is maintained, the CPU 60a maintains the current state of both the probability variation flag and the operation flag.

  By executing the big hit game and the small hit game in this way, in the embodiment, in the first round of the jump-up big hit game, the 2R special probability variable big hit game, the 2R normal probability variable big hit game and the small hit game and the opening of the door 42 are opened. A state is created in which the aspects are identical. That is, in the jump-up jackpot game, the time from the first opening of the opening / closing door 42 in the first round to the end of the second opening, the 2R special probability variable big hit game, the 2R normal probability variable big hit game, and the small hit The time from the first opening of the open / close door 42 to the end of the second opening in the game is set to “1.62 (seconds)”. In other words, in the jump-up big hit game, 2R special probability variable big hit game, 2R normal probability variable big hit game and small hit game, the door is opened in the same open mode for "1.62 (seconds)" after the hit game starts. 42 is opened. That is, in the pachinko machine 10 of the embodiment, even if the player visually recognizes the opening operation mode of the door 42, it is difficult to distinguish between the 2R special probability variable big hit game, the 2R normal probability variable big hit game, and the small hit game. is there. Also, in the pachinko machine 10 of the embodiment, in the jump-up big hit game, the 2R special probability variable big hit game, the 2R normal probability variable big hit game and the small hit game are played until the third release after the start of the first round. Is not at all distinguished. As a result, even if the open / close door 42 is opened twice in a short time (0.06 seconds), the player can jump-up big hit game, 2R special probability variable big hit game, 2R normal probability variable big hit game and small It is impossible to distinguish which winning game is given.

  In addition, in the 15R probability variation jackpot game, step-up jackpot game, 15R shortened probability variation jackpot game, 15R probability variation secret jackpot game, 15R non-probability variation jackpot game, and 15R shortened non-probability jackpot game up to the first to eighth rounds The opening mode of the door 42 is the same. Therefore, from the opening mode of the open / close door 42 up to 1 to 8 rounds, 15R probability variation jackpot game, step-up jackpot game, 15R shortened probability variation jackpot game, 15R probability variation secret jackpot game, 15R non-probability variation jackpot game and 15R non-probability variation jackpot It is not possible to recognize which jackpot game of the games.

  In addition, in the ninth round of the step-up jackpot game, the opening mode until the door 42 is opened and closed seven times, the 15R shortened probability variable hit game, and the 15R shortened uncertain variable hit game from the ninth to the 15th round of the door 42 The opening mode is the same. That is, in the ninth round of the step-up jackpot game, the opening operation mode until the open / close door 42 opens and closes seven times, the 15R shortened probability variable jackpot game, and the doors 42 to the ninth to fifteenth rounds of the 15R shortened non-probable bonus game. The opening operation mode is apparently the same. For this reason, from the eighth round onward, until the open / close door 42 is opened and closed seven times, it is recognized from the open mode whether the big hit game is a step-up big hit game, a 15R shortened probability variable big hit game, or a 15R shortened uncertain variable big hit game. Can not.

  In the 15R probability variation concealment jackpot game and the 15R non-probability variation jackpot game, the period during which the winning rate improvement state is given after the jackpot game ends (until 50 symbol variation effects are executed) is the same. On the other hand, in the 15R probability variation concealment big hit game, the probability variation state is given after the big hit game ends, whereas in the 15R non-probability big hit game, the probability variation state is not given after the big hit game ends. In other words, when a big hit game of 15R probability variation concealment big hit game or 15R non-probability big hit game is awarded, and after the symbol variation effect is executed 50 times, the probability variation state is granted Since it is not possible to specify whether or not the winning rate improvement state has been given, it can be expected that the probability variation state has been given.

(Operation of Example)
Next, the operation of the pachinko machine 10 according to the above-described embodiment will be described.

  Pachinko balls launched into the game area 20a along the guide rails 21 provided on the game board 20 come into contact with the game nails provided on the game board 20 while changing the flow direction. When the pachinko balls flowing down the game area 20a win the upper and lower start winning openings 26a and 26b of the start winning apparatus 26, the special figure display on the special figure display 50 is displayed based on the control of the control apparatus. Is started, and the symbol variation effect on the symbol display device 18 is started. Then, as a result of the special symbol variation display (design variation effect), when a predetermined big hit symbol (special symbol) is displayed on the special symbol indicator 50, a big hit occurs, and the special symbol indicator 50 has a predetermined small bonus symbol ( When a special figure is displayed, a small hit occurs. Then, a big hit game according to the type of the special figure displayed on the special figure display 50 is given with the occurrence of the big hit, and a small hit game is given with the occurrence of the small hit, the game board The opening / closing operation is performed according to the type of the big hit game or the small hit game to which the opening / closing door 42 of the special winning device provided below the 20 is provided.

  Here, since the open / close door 42 of the special prize-winning device 30 is opened with the occurrence of a big hit game or a small hit game, the open / close door 42 always closes the special winning opening 33, and the game board 20 The pachinko balls flowing down the game area are likely to come into contact with the open / close door 42 and be damaged. In the special winning device 30 of the embodiment, the shielding member 45 is disposed so as to be spaced apart in the player's line-of-sight direction with respect to the special winning opening 33 (opening / closing door 42), thereby opening and closing the special winning opening 33. The visibility of the door 42 is hindered. For this reason, even if the opening / closing door 42 is damaged, it is possible to prevent the player from seeing the damage by blocking the player's line of sight with the shielding member 45, and to prevent the decorativeness of the pachinko machine 10 from being impaired. In addition, the special prize-winning device 30 is disposed at a lower position of the game board 20 and is configured such that at least the full length of the free end portion of the open / close door 42 in the closed position overlaps the shielding member 45 in the front-rear direction. Further, since the visibility of the open / close door 42 from the player side can be further reduced, it is possible to effectively prevent the player from recognizing scratches and the like generated on the open / close door 42. At this time, the pachinko ball is configured to be able to pass between the opening / closing door 42 and the shielding member 45 with the special winning opening 33 closed, so that the shielding member 45 is opened with the opening / closing door 42 opening the special winning opening 33. Will not be an obstacle to the pachinko ball winning the special winning opening 33.

  The special winning device 30 is provided with an LED 38a that emits light toward the opening direction of the special winning opening 33, and the light from the LED 38a passes through the opening / closing door 42 and the shielding member 45. It is irradiated to the front of the game board 20. In this way, by irradiating the light of the LED 38a to the opening / closing door 42, the shadow of the opening / closing door 42 becomes inconspicuous, and the possibility that the player can identify the damage etc. of the opening / closing door 42 effectively. Can be reduced. Similarly, since the light of the LED 38a is also applied to the shielding member 45, shadows such as scratches generated on the shielding member 45 can be made inconspicuous, and the scratches generated on the shielding member 45 cause the pachinko machine 10 It can also prevent the decorativeness from being impaired.

  Further, the shielding member 45 is positioned in front of the opening / closing door 42 with the special winning opening 33 opened, and the free end portion of the opening / closing door 42 located at the open position is concealed by the shielding member 45. . Accordingly, even when the opening / closing door 42 is in the open position, the visibility of the opening / closing door 42 is hindered by the presence of the shielding member 45, making it difficult for the player to distinguish the opening / closing door 42. It is possible to make it difficult for a player to recognize a scratch or the like generated on the back side.

  By the way, in the 15R shortened probable big hit game, the 15R shortened non-probable big hit game, and the step-up big hit game, the opening / closing operation mode of the open / close door 42 of the special winning device 30 is the same until the eighth round game of each big hit game. It is configured. And in the ninth round game of the step-up jackpot game, the opening mode until the open / close door 42 of the special prize winning device 30 opens and closes seven times, and the ninth round in the 15R shortened probability variable jackpot game and the 15R shortened uncertain variable jackpot game In the opening mode of the open / close door 42 up to the 15th round, the same opening operation is repeated for a short time. Accordingly, when any of the big hit games of 15R shortened probability variation big hit game, 15R shortened non-probable big hit game and step-up big hit game is performed, when the round game of the ninth round is performed, the door 42 is opened. It is possible to make the player pay attention to whether or not the eighth opening operation is performed. Here, as described above, in the special winning device 30 according to the embodiment, since the shielding member 45 is disposed in front of the opening of the special winning opening 33, the opening / closing door 42 is provided. The opening / closing operation of 42 is difficult for the player to see. This makes it difficult to determine whether or not the opening / closing door 42 has been opened for a short time in a 15R shortened probability variation jackpot game, a 15R shortened uncertain variation jackpot game, and a step-up jackpot game. Can be prevented from being predicted by the player.

  That is, the distinction between the 15R shortened probability variation big hit game and the 15R shortened uncertain variable big hit game and the step-up big hit game can be prevented from being distinguished from the opening operation of the opening / closing door 42. It can attract attention and increase the expectation for the continuation of the round game. When the 15R shortened probability change big hit game, the 15R shortened non-probable big hit game and the step-up big hit game are determined, the opening / closing door 42 is the eighth round in the ninth round game after the step-up big hit game is started. Whether or not it is a step-up big hit game is determined depending on whether or not a specific display is displayed on the symbol display device 18 by the timing when it is released. As a result, when the 15R shortened probable big hit game, the 15R shortened non-probable big hit game, and the step-up big hit game are determined, the eighth round is released in the ninth round game after the start of the step-up big hit game. It is possible to attract the player's attention as to whether or not a specific display is displayed on the symbol display device 18 in the hit effect up to the point in time (that is, whether or not the hit game is a step-up jackpot game). That is, by making it difficult to visually recognize the opening operation of the opening / closing door 42, the player's attention to the opening / closing door 42 can be diverted, and the degree of attention of the hit effect performed on the symbol display device 18 can be increased, and the effect of the effect can be increased. It is possible to maximize the effect. In this way, while making the player pay attention to the opening operation of the door 42 in a step-up big hit game for a short time, the door 42 is covered with the shielding member 45 so that it is difficult for the player to discriminate. By performing the hit effect with a high degree of attention of the player, it is possible to enjoy the effect by the opening / closing operation of the door 42 and the effect on the symbol display device 18 in a balanced manner.

  In addition, since it is difficult for the player to understand the short-time opening and closing operation of the door 42 in the 15R shortened probability variable hit game, 15R shortened uncertain variable hit game and step-up jackpot game, the 15R shortened probability variable hit game and the 15R shortened non-change variable hit game It is possible to effectively conceal the progress of the round game. Furthermore, in the step-up jackpot game, the unnaturalness caused by the opening / closing operation of the open / close door 42 for a short time during the round game can be eliminated.

  In addition, in the first round game of the jump-up jackpot game, the opening mode until the opening / closing door 42 of the special winning device 30 is opened and closed twice, the 2R special probability variable big hit game, the 2R normal probability variable big hit game, and the special in the small hit game The opening mode of the opening / closing door 42 of the winning device 30 is the same. As a result, when any big hit game of 2R special probability variable big hit game, 2R normal probability variable big hit game or jump-up big hit game is performed or when a small hit game is performed, the door 42 is opened for the third time from the start of the hit game. It is possible to make the player pay attention to whether or not to perform the opening operation. Here, as described above, in the special winning device 30 according to the embodiment, since the shielding member 45 is disposed in front of the opening of the special winning opening 33, the opening / closing door 42 is provided. The opening / closing operation of 42 is difficult for the player to see. This makes it difficult to determine whether or not the opening / closing door 42 has been opened for a short time in 2R special probability variable big hit games, 2R normal probability variable big hit games, small hit games and jump-up big hit games. Therefore, it is possible to prevent the game content from being predicted by the player.

  That is, since the distinction between the 2R special probability variable big hit game, the 2R normal probability variable big hit game and the small hit game, and the jump-up big hit game can be prevented from being distinguished from the opening operation of the opening / closing door 42, it is performed by the symbol display device 18. Attracting attention to the production that can be played, it can raise the expectation for the continuation of the round game. When the jump up jackpot game, the 2R special probability variable big hit game, the 2R normal probability variable big hit game, and the small hit game are determined, the open / close door 42 is opened three times in the first round after the jump up jackpot game is started. Whether or not the game is a jump-up jackpot game is determined based on whether or not the second specific display is displayed on the symbol display device 18 by the timing when the game is released. As a result, when the jump-up jackpot game, 2R special probability variable big hit game, 2R normal probability variable big hit game and small hit game are determined, the third release is performed in the first round after the jump-up jackpot game starts. Attracting the player's attention to whether or not the second specific display is displayed on the symbol display device 18 (ie, whether or not the winning game is a jump-up jackpot game) in the winning effect up to the point in time Can do. That is, by making it difficult to visually recognize the opening operation of the opening / closing door 42, the player's attention to the opening / closing door 42 can be diverted, and the degree of attention of the hit effect performed on the symbol display device 18 can be increased, and the effect of the effect can be increased. It is possible to maximize the effect. In this way, while making the player pay attention to the opening operation of the door 42 for a short time in the jump-up jackpot game, the door 42 is covered with the shielding member 45 so that it is difficult for the player to discriminate. By performing the hit effect with a high degree of attention of the player, it is possible to enjoy the effect by the opening / closing operation of the door 42 and the effect on the symbol display device 18 in a balanced manner.

  In addition, since 2R special probability variable big hit game, 2R normal probability variable big hit game and jump-up big hit game can make it difficult for the player to understand the opening and closing operation of the door 42 for a short time, 2R special probability variable big hit game and 2R special probability variable big hit game are progressing. Can be effectively concealed. Furthermore, in the jump-up jackpot game, the unnaturalness caused by the opening / closing operation of the open / close door 42 for a short time during the round game can be eliminated. In addition, since the player can hardly recognize the opening / closing operation of the opening / closing door 42 in the 2R special probability variation big hit game and the 2R normal probability variation big hit game, it prevents the player from feeling uncomfortable due to the opening / closing door 42 being opened and closed for a short time. Can do.

  In addition, since the opening mode of the opening / closing door 42 of the 2R normal probability variable big hit game and the special winning device 30 is the same as the opening mode of the opening / closing door 42 of the small hit game, the 2R normal probability variable big hit game or the small hit game is opened. When the open / close door 42 of the special winning device 30 is opened / closed in this manner, it cannot be recognized whether or not a certain change state is given. As a result, it is possible to conceal whether the 2R normal probability variation big hit game or the small hit game has been awarded, and the game can be continued with the expectation that the probability variation state has been given.

  Furthermore, in the special prize-winning device 30 of the embodiment, the ridge 32b extends along the free edge of the open / close door 42 with the special prize opening 33 closed. For this reason, even if an unauthorized device is temporarily inserted into the game area 20a of the game board 20, it is difficult for the unauthorized device to be blocked by the protrusion 32b and to be hooked on the free edge of the door 42. Unauthorized opening of the opening / closing door 42 can be prevented. Furthermore, since the upper surface 32c of the protrusion 32b is formed in an inclined shape that inclines downward toward the front, even if an unauthorized device is brought close to the free end of the open / close door 42, the protrusion It can be guided to move away from the opening / closing door 42 along the inclination of the upper surface 32c of 32b, and it is possible to more effectively prevent an unauthorized device from being caught on the free end of the opening / closing door 42. Further, even if the free end portion of the ridge portion 32b is formed in a curved shape, it is possible to prevent an unauthorized instrument from being caught on the free end portion of the open / close door 42. Can be prevented more effectively.

  Further, in the special prize device 30 of the embodiment, the support parts 46 and 46 of the shielding member 45 are formed so as to protrude forward from the opening side edges of the special prize opening 33 on the left and right sides, and in front of the opening / closing door 42. The shielding member 45 is located. That is, even if it is attempted to intrude unauthorized equipment from the left and right sides or the front of the opening / closing door 42, it is difficult to reach the special winning opening 33 (opening / closing door 42) due to the blocking member 45 and the support portions 46, 46. In addition, unauthorized opening of the open / close door 42 by an unauthorized device can be more effectively prevented.

  On the other hand, in the case of maintenance of the pachinko machine 10 (special winning device 30), winning detection confirmation check, or compensation for shortage of prize balls performed at the amusement store, the door 42 is manually forced from the viewpoint of workability. Must be able to open. Here, in the special prize winning device 30 of the embodiment, a locking recess 32d is formed in the ridge portion 32b, and a part of the free end portion of the open / close door 42 faces the locking recess 32d. By using the locking recess 32d, the operator can hook his / her fingers on the opening / closing door 42, and a manual opening operation can be performed. In this way, by forming the protrusion 32b and the locking recess 32d, the manual opening of the opening / closing door 42 is permitted, and the opening / closing door 42 is prevented from being illegally opened. It is possible to realize the conflicting purposes in a balanced manner.

  Further, the locking recess 32d is provided at the left end portion of the protrusion 32b, so that the locking recess 32d is compared with a configuration in which the locking recess 32d is provided at an intermediate position of the protrusion 32b. Therefore, the operator can easily catch the finger, and the manual forcible opening operation can be easily performed. Here, even if the locking recess 32d is positioned at the left end of the ridge portion 32b so that the operator's fingers can be easily hooked on the open / close door 42, the left and right opening side edge portions of the special winning opening 33 as described above. Since the support portions 46, 46 of the shielding member 45 are formed so as to protrude forward, the support portions 46, 46 function as restricting means for restricting the intrusion of an unauthorized instrument into the locking recess 32d. The effect of preventing the unauthorized opening operation of the opening / closing door 42 is not impaired, and the allowance for the forced opening operation of the opening / closing door 42 manually and the prevention of the unauthorized opening operation of the opening / closing door 42 are balanced. It can be realized.
