Description

  The present invention relates to a gaming machine such as a pachinko machine, and more particularly to a gaming machine in which two types of symbol variation games are played.

  2. Description of the Related Art In recent years, a gaming machine that plays a game using two types of special symbols (a first special symbol and a second special symbol) has been proposed in order to increase the variation of game characteristics and enhance the interest of the game. The special symbol is a symbol determined by the game control means. For example, information such as the type of jackpot (probability variation jackpot that becomes a probability variation state or non-probability variation jackpot that does not become a probability variation state), and the number of rounds in the jackpot gaming state Is included.

  In addition, during the probability variation state, the second symbol variation game is frequently performed by facilitating the winning of the game ball to the second starting prize-winning device, thereby increasing the probability of winning a small hit and increasing the number of prize balls. A gaming machine configured as described above has been proposed (see, for example, Patent Document 1). That is, since the prior art described in Patent Document 1 provides a new game characteristic (the number of prize balls) during the probability variation state, it can enhance the interest of the game.

JP 2006-6411 A (Claims 1, 2, [0105], FIG. 4, etc.)

  However, the longest time in the game is the normal state before the big hit gaming state or the state before the symbol change game is a big hit in the probability changing state. In addition, in the prior art described in Patent Document 1, the interest is enhanced when the symbol variation game is a small hit in the probability variation state, but the interest in other states is different from that of other general gaming machines. It doesn't change. Therefore, also in this case, the interest of the game cannot be increased so much, and the player is bored.

  Moreover, it is unlikely that the technique described in Patent Document 1 is acceptable to all players. This is because the preference of the symbol variation game differs depending on the player. For example, there is a player who wants a symbol variation game with a short game production time and a simplified game production content because he wants to know early whether the result of the symbol variation game will be a big hit To do. On the other hand, there is a player who seeks a symbol variation game with a long game effect production time and a complicated game effect production content because he wants to enjoy the symbol variation game thoroughly. Therefore, although it is a technique for enhancing the interest of a game, it may be a cause of a decrease in interest. In view of this, a technique has been proposed in which a player selects a game effect suitable for his / her preference by operating an effect change means such as an effect button during the game. However, even if the effect changing means is operated, the effect contents can only be changed, and the effect time cannot be changed. Therefore, the interest of the game cannot be sufficiently enhanced.

  The present invention has been made in view of the above-mentioned problems, and its purpose is to make it possible to select a symbol variation game that suits the player's preference more than when using the effect changing means. The object is to provide a gaming machine that can sufficiently enhance interest.

  In order to solve the above-mentioned problem, the invention according to claim 1 is different from the first start winning device disposed at a predetermined position on the game board surface and the first start winning device on the game board surface. And a first special symbol display unit for displaying a first symbol variation game for varying the first special symbol in response to a winning of a game ball in the first starting prize device. And a second special symbol display unit for displaying a second symbol variation game for varying the second special symbol, triggered by the winning of the game ball to the second start winning device, a closed state not accepting the game ball, and A gaming machine comprising a large winning device that can be switched to an open state in which a game ball can be easily received, and a game control means for controlling the entire gaming machine, wherein the game in the first symbol variation game or the second symbol variation game Production time And variation pattern group storage means for storing a plurality of variation pattern groups to which variation patterns for specifying the production contents are assigned, and the game control means determines whether or not the result of the first symbol variation game is a big hit A first big hit determining means for determining whether or not the first big hit gaming state in which the big winning device is in the open state for the big hit when the determination result by the first big hit determining means is a big hit. The big hit game state giving means, the second big hit determining means for determining whether or not the result of the second symbol variation game is a big hit, and the determination result by the second big hit determining means is a big hit. The determination result by the second big hit game state giving means for giving the second big hit game state in which the winning device is in the released state for the big hit and the second big hit determination means are If the result of the second symbol variation game is a small hit when there is a gap, and the determination result by the small hit determination means is a small hit, the big win Based on the determination results by the small hit gaming state giving means for giving the small hit gaming state in which the device is in the open state for small hits, the first big hit determining means, the second big hit determining means, and the small hit determining means And a variation pattern determining means for determining the variation pattern, wherein the probability that the determination result by the small hit determination means is a small hit is set higher than the probability that the determination result by the second big hit determination means is a big hit When the first symbol variation game is started after the determination result by the small hit determination unit is a small hit, the variation pattern determination unit is configured to display the variation pattern group recording. The gist of the gaming machine is that a variation pattern group different from the currently selected variation pattern group is selected from the plurality of variation pattern groups stored in the storage means.

  Therefore, according to the first aspect of the present invention, the variation pattern group can be changed by the player simply winning the game ball in the second starting prize-winning device to obtain a small hit, and thus the changed variation pattern. Based on the variation pattern distributed to the group, the first symbol variation game can be started which has different performance time and performance contents from the current one. That is, compared with the case where only the contents of the effect are changed by using the effect changing means, the first symbol variation game more suited to the player's preference can be selected, so that the interest of the game can be sufficiently enhanced.

  Here, as the first special symbol display unit and the second special symbol display unit suitable in the present invention, an electric symbol display unit such as a liquid crystal type, a dot matrix type, an electroluminescence element type, a seven segment type, etc. In addition, a mechanical symbol display unit such as a drum type or a belt type can be used, but it is particularly preferable to use an electric symbol display unit, and more particularly a liquid crystal type among electric symbol display units. It is preferable to use those. In this way, it becomes easy to execute complex effects in the first symbol variation game and the second symbol variation game.

  Further, the grand prize winning device can be switched between a closed state in which no game ball is received and an open state in which the game ball is easily received. In addition, as a specific example of the closed state, for example, a state where the big prize opening door of the big prize winning device is completely closed can be cited. On the other hand, as a specific example of the open state, for example, a state in which the grand prize opening door is completely opened can be cited.

  Note that the number of variation pattern groups stored by the variation pattern group storage unit may be two, or three or more. If the number of the variation pattern groups increases, the choices of the variation pattern groups increase, so that the contents of the first symbol variation game executed based on the variation patterns can be easily matched to the player's preference. On the other hand, when the number of variation pattern groups decreases, it is not necessary to continuously change the variation pattern group by winning a game ball several times in order to execute the first symbol variation game that matches the player's preference. Therefore, it is possible to quickly change the variation pattern group and the first symbol variation game. In addition, by reducing the number of variation pattern groups, it is possible to suppress an increase in the capacity of data stored in the variation pattern group storage means, and thus reduce the burden on the variation pattern determination means for selecting the variation pattern group. it can.

  Here, the method by which the variation pattern determination means selects a variation pattern group different from the currently selected variation pattern group is not particularly limited. For example, when three of the variation pattern group A, the variation pattern group B, and the variation pattern group C are stored in the variation pattern group storage unit, the variation pattern determination unit determines whether the result of the second symbol variation game is a small hit. Alternatively, the variation pattern group may be selected in the order of the variation pattern group A → the variation pattern group B → the variation pattern group C → the variation pattern group A →. Further, the variation pattern determining means may randomly select any one of the variation pattern groups A to C based on random number lottery. Furthermore, the variation pattern determining means may select any one of the variation pattern groups A to C according to the type of the small hit symbol.

  The probability that the determination result by the small hit determination means is a small hit is not particularly limited, but is preferably 80% or more, for example. If the probability that the determination result by the small hit determination means is a small hit is less than 80%, even if the game ball is won in the second start winning device, the probability that the variation pattern group is changed is low. Changing the variation pattern group takes time.

  The gist of the invention described in claim 2 is that, in claim 1, the variation time of the game effect specified by the variation pattern is different for each of the plurality of variation pattern groups.

  Therefore, according to the second aspect of the present invention, when the player is demanding efficient digestion of the symbol variation game, the player causes the second start winning device to win the game ball, thereby changing the game effect. It is possible to cause the variation pattern determining unit to select a variation pattern group having a relatively short time. On the other hand, if the player prefers to slowly digest the symbol variation game, the variation pattern group in which the variation time of the game effect is relatively long by allowing the player to win a game ball in the second start winning device. Can be selected by the variation pattern determining means. That is, the variation pattern group can be selected according to the player's preference.

  According to a third aspect of the present invention, in the second aspect of the present invention, there is a probability that a notice that suggests a possibility that a result of the first symbol variation game or the second symbol variation game is a big hit based on the variation pattern appears. The probability that the notice appears based on the variation pattern distributed to the variation pattern group that is different for each of the plurality of variation pattern groups and that has a relatively long variation time of the game effect is relative to the variation time of the game effect. The gist of the present invention is that it is set to be larger than the probability that the notice appears based on the variation pattern assigned to the short variation pattern group.

  Therefore, according to the third aspect of the present invention, when a variation pattern group with a relatively long variation time of the game effect is selected, a notice is likely to appear. It can be performed.

  The advance notice suggesting the possibility that the result of the first symbol variation game or the second symbol variation game may be a big hit is a reach announcement for announcing reach, a big hit announcement for announcing a big hit, or a big hit decision for announcing the decision of a big hit For example, there is a notice and a specific jackpot confirmation notice for notifying that the first symbol variation game or the second symbol variation game stops at a specific jackpot symbol and becomes a big hit.

  As specific examples of the notice, characters, symbols, characters, etc. explicitly suggest the possibility that the result of the first symbol variation game or the second symbol variation game will be a big hit, or those that suggest implicitly It is done. For example, the letters “reach”, “big hit”, and “probable big hit” are displayed as specific examples of the notice that explicitly suggests that the result of the first symbol fluctuation game or the second symbol fluctuation game may be a big hit. The production to do. On the other hand, a specific example of a notice that implicitly suggests that the result of the first symbol variation game or the second symbol variation game may be a big hit is an effect of displaying a character (for example, a red robot). It is done. As specific examples of the notice, the volume, type, etc. of the sound generated from the sound generating means is different from the normal effect where the notice is not executed, the emission color, brightness, lighting time, and blinking of the light emitting means. An effect such as an interval that is different from the normal effect may be mentioned.

  According to a fourth aspect of the present invention, in the third aspect, the variation pattern allocated to the variation pattern group includes a variation pattern for a loss effect that displays a combination of patterns that are lost without a reach effect, and a reach effect. Including a variation pattern for a lose reach production that displays a combination of symbols of a loss through, and a variation pattern for a big hit production that displays a combination of symbols of a jackpot through a reach production, The variation time of the game effect specified by the variation pattern for the jackpot effect, the variation pattern for the lose reach effect, and the probability that the notice appears based on the variation pattern for the jackpot effect are the plurality of variation patterns. The gist is that it differs from group to group.

  Therefore, according to the fourth aspect of the present invention, when the player is demanding a game characteristic in which the result of the first symbol variation game immediately becomes a big hit, the player wins a game ball in the second start winning device. By doing so, it is possible to change to a variation pattern group in which the reach production time is relatively short and the notice is less likely to appear. On the other hand, when the player is seeking a game characteristic in which the result of the first symbol variation game is a big hit through various effects, the player makes the second start winning device win a game ball, thereby reaching reach. It is possible to change to a variation pattern group in which the presentation time is relatively long and the notice is likely to appear relatively easily.

  A fifth aspect of the present invention is the invention according to any one of the first to fourth aspects, wherein a plurality of types generated based on the first special symbol and the second special symbol at a substantially central portion on the game board surface. And a first display winning device and a big winning device are disposed in a lower area of the symbol display device on the game board surface, and A two-start winning device is disposed in the right region of the symbol display device on the game board surface, and aims at the second starting winning device in a region between the second starting winning device and the big winning device. A winning prevention member for preventing a game ball that has been fired from winning into the big winning device is provided, and when the second big hit gaming state or the small hit gaming state is given, the big winning device is in the open state. The time The special winning device as its gist to set shorter than the time to be the open state when imparting gaming state.

  In the present invention, in order to easily change the variation pattern group, it is necessary to facilitate the winning of the game ball to the second start winning device and to increase the probability that the result of the second symbol variation game will be a small hit. is there. However, when the result of the second symbol variation game is a small hit, the big winning device is opened, so that the player does not make the first starting winning device win the game ball and the second starting winning device. There is a possibility that a small hit will be frequently generated by intentionally winning a game ball and a large number of award balls will be obtained.

  Accordingly, in claim 5, by providing a prize prevention member in a region between the second starting prize winning device and the big winning prize device, the game ball launched aiming at the second starting prize winning device is directly used as the big prize winning device. Preventing winnings. In addition, when the second big hit gaming state or the small hit gaming state is given, the time for the big winning device to be opened is shorter than the time for the big winning device to be opened when the first big hit gaming state is given. It is set. Therefore, for example, even if the first starting prize device does not win the game ball and only the second starting prize device wins the game ball, and the result of the second symbol variation game is a small hit, the big winning device is released. Since the time to enter the state is short, it becomes difficult to win a game ball and it is difficult to acquire a prize ball. As a result, the player has no idea of intentionally winning the game ball in the second start winning device without causing the first start winning device to win the game ball. Therefore, it is possible to cause the player to play a game as intended by the designer.

  Here, examples of the winning prevention member include a game nail projecting from the game board surface, and an accessory disposed on the game board surface.

  In addition, when the second big hit gaming state or the small hit gaming state is given, the time for the big winning device to be in the released state, and when the first big hit gaming state is given, the big winning device is released. As a method of setting the time shorter than the time to enter the state, the number of rounds in the second big hit gaming state or the little hit gaming state is set to be smaller than the number of rounds in the first big hit gaming state, The opening time of the big winning device per round in the big hit gaming state or the small hit gaming state is set shorter than the opening time of the big winning device per round in the first big hit gaming state, etc. Is mentioned.

  According to a sixth aspect of the present invention, in any one of the first to fifth aspects, the game ball won in the first start winning device is stored as a first start holding ball, and the second start winning device is stored in the second start winning device. A holding storage means for storing a winning game ball as a second start holding ball is provided, wherein the second start holding ball is not stored in the holding storage means, and the first start holding ball is stored in the holding memory. When stored in the means, the first big hit determination means determines whether the result of the first symbol variation game is a big hit based on the first start holding ball, and the second start hold When a ball is stored in the holding storage unit, the second big hit determination unit determines whether or not the second starting hitting ball is stored in the holding storage unit. Previous based on sphere The second symbol variable game results as its gist to determine whether becomes jackpot.

  Therefore, according to the sixth aspect of the present invention, when the second start hold ball is stored in the hold storage means, even if the first start hold ball is stored, the second symbol variation is preferentially performed. The game starts. For this reason, as soon as the player wins the game ball in the second start winning device, the determination as to whether or not the result of the second symbol variation game will be a big win or a small win starts. Can be changed quickly.

  As described above in detail, according to the inventions described in claims 1 to 6, a game that can improve the interest of the game by making it possible to select a group of symbol variation games according to the player's preference. Machine can be provided. In particular, according to the invention described in claim 6, the variation pattern group can be changed quickly.

Further, a front frame 14 is assembled on the front side of the middle frame 12 so as to be opened and closed in a laterally open state. The front frame 14 has a structure in which an upper ball tray 15 is integrally assembled below the window 14a while having a window 14a at the center. A glass frame (not shown) for seeing through and protecting the game board 13 disposed inside the machine is assembled on the back side of the front frame 14. Further, an upper frame lamp 16a, a left frame lamp 16b, and a right frame lamp 16c are provided on the front surface of the front frame 14. Each of the frame lamps 16a to 16c is a light emitting means including a light emitter (not shown) (not shown), and is configured by covering the light emitter with a lens member. In these frame lamps 16a to 16c, light emission effects such as lighting (flashing) and light extinction are executed according to various game performance modes (big hit, reach, etc.) of the pachinko machine 10.

  Further, as shown in FIG. 1, a left speaker 17a, which is a sound generating means, is disposed at the upper left portion of the front frame 14, and a right speaker 17b, which is also a sound generating means, is provided at the upper right portion of the front frame 14. It is arranged. The left speaker 17a and the right speaker 17b are for executing sound effects for outputting various sounds. The left speaker 17a and the right speaker 17b are mounted on the back side of the front frame 14, and a plurality of sound emitting holes are formed at locations corresponding to the left speaker 17a and the right speaker 17b on the front side of the front frame 14.

  Further, a lower ball tray 18 is assembled to be openable and closable below the front frame 14 on the front side of the middle frame 12. On the right side of the lower ball tray 18 is mounted an operation handle 19 that is turned by the player when the game ball is launched. Further, on the left side of the lower ball tray 18, an ashtray 20, a woofer speaker 17c, which is a sound generating means, and the like are disposed. Note that the woofer speaker 17c is used to execute sound effects for outputting various sounds, and is attached to the middle frame 12.

  As shown in FIGS. 1 and 2, an inner rail 41 a and an outer rail 41 b are laid in a substantially circular shape on the game board surface 13 a of the game board 13. A game ball launched when the operation handle 19 is operated passes through a launch path generated between the inner rail 41a and the outer rail 41b. In addition, a plurality of game nails 81 and the like projecting from almost the entire area of the game board surface 13a are disposed in the game area, which is the inner area of the inner rail 41a and the outer rail 41b. The game nail 81 is adapted to change the direction of the game ball flowing down in the game area.

  Further, a frame-shaped center accessory 60 having a symbol display device 61 is mounted at a substantially central portion on the game board surface 13 a of the game board 13. In addition, although the symbol display device 61 of this embodiment is a liquid crystal type, a dot matrix type, an electroluminescence element type, and a 7 segment type symbol display device may be used. As shown in FIG. 2, the visual display unit (display screen) included in the symbol display device 61 includes a first effect symbol display unit 71 and a second effect symbol display unit 72. In the first effect symbol display unit 71 and the second effect symbol display unit 72, a game effect (display effect) based on a fluctuating image (or image display) is performed. Then, in the first effect symbol display unit 71, in association with the display effect, a first symbol combination game in which a plurality of types of first effect symbols E1 are variably displayed in three columns and a symbol combination is derived is performed. ing. The first effect symbol E1 is a symbol indicating eight numbers “1” to “8”. In addition, in the second effect symbol display unit 72, in association with the display effect, a second symbol combination game in which a plurality of types of second effect symbols E2 are variably displayed in three columns and a symbol combination is derived is performed. ing. The second effect symbol E2 is a symbol indicating eight numbers “1” to “8”.

  As shown in FIGS. 1 and 2, in the lower region of the center accessory 60 (symbol display device 61) on the game board surface 13a, a first start winning device 21 having a first start winning port 21a is formed. It is arranged. The first starting prize-winning device 21 is integrally configured with an ordinary electric accessory consisting of a pair of blade members 21b. The pair of blade members 21b are configured to open and close by the excitation action of the ordinary electric accessory solenoid SOL1 (see FIG. 3). Further, a first start port switch SE1 (see FIG. 3) for detecting a game ball that has entered the first start winning port 21a is provided in the back of the first start winning device 21. The first start port switch SE1 is turned on when a game ball won in the first start winning device 21 is detected, and outputs a first winning signal. On the other hand, the first start port switch SE1 is turned off when no game ball is detected, and does not output the first winning signal. When the first winning signal is output, the first symbol variation game is performed by the first special symbol display unit 51 and the first effect symbol display unit 71 is associated with the first symbol variation game. A first symbol combination game is performed, and a predetermined number (three in this embodiment) of prize balls is paid out.

  As shown in FIG. 1, a large winning device 23 is disposed in a lower region of the first start winning device 21 on the game board surface 13a. The special winning device 23 is integrally formed with a special electric accessory consisting of a special winning opening door 23a. The special winning opening door 23a can be switched between a closed state in which the game ball is not received and an open state in which the game ball is easily received by the exciting action of the special winning solenoid SOL2 (see FIG. 3). In the present embodiment, the “closed state” means a state in which the big prize opening door 23a is completely closed, and the “open state” means a state in which the big prize opening door 23a is completely opened. Further, a count switch SE3 (see FIG. 3) for detecting a winning game ball is provided in the back of the big winning device 23. When a game ball is detected by the count switch SE3, a predetermined number (10 in this embodiment) of award balls is paid out.

  As shown in FIGS. 1 and 2, a gate 25 having a function of detecting the passage of a game ball is provided in the left area of the center accessory 60 (symbol display device 61) on the game board surface 13a. Behind the gate 25 is provided a gate switch SE4 (see FIG. 3) for detecting the game ball that has passed. Note that, when a game ball is detected by the gate switch SE4, a random number is acquired, and based on a result of determining whether or not the acquired random number is a predetermined random value, the ordinary electric accessory solenoid SOL1 is driven. . Since the pair of blade members 21b are opened by such determination (hit determination), it becomes easy for the game ball to win the first start winning device 21.

  A second start winning device 22 having a second start winning port 22a is disposed in the right region of the center accessory 60 (the symbol display device 61) on the game board surface 13a. That is, the second start winning device 22 is disposed on the game board surface 13a at a location different from the first start winning device 21. A second start port switch SE2 (see FIG. 3) for detecting a game ball won in the second start winning port 22a is provided in the back of the second start winning device 22. The second start port switch SE2 is turned on when a game ball won in the second start winning device 22 is detected, and outputs a second winning signal. On the other hand, the second start port switch SE2 is turned off when no game ball is detected and does not output the second winning signal. When the second winning signal is output, the second symbol variation game is played by the second special symbol display unit 52, and the second effect symbol display unit 72 is associated with the second symbol variation game. A second symbol combination game is performed, and a predetermined number (three in this embodiment) of prize balls is paid out.

  As shown in FIGS. 1 and 2, a first special symbol display unit 51 having a visible display unit is disposed on the lower left side of the center accessory 60. The first special symbol display unit 51 displays a first symbol variation game that fluctuates the first special symbol B1 in response to the winning of the game ball to the first start winning device 21, and the result of the first symbol variation game is displayed. As a result, the display results of the big hit, the small hit and the loss are displayed. For example, when the result of the first symbol variation game is a big hit, at the end of the first symbol variation game, symbols indicating 18 numbers “1” to “18” are displayed as the first special symbol B1. Further, when the result of the first symbol variation game is a small hit, a symbol indicating a number “0” is displayed as the first special symbol B1 at the end of the first symbol variation game. Further, when the result of the first symbol variation game is lost, at the end of the first symbol variation game, a symbol “-” indicating a loss is displayed as the first special symbol B1. The first special symbol B1 is a symbol (a symbol that is not a character or a number) that does not make sense (see FIG. 2).

  As shown in FIGS. 1 and 2, a second special symbol display unit 52 having a visual display unit is arranged on the lower left side of the center accessory 60 and on the right side of the first special symbol display unit 51. It is installed. The second special symbol display unit 52 displays a second symbol variation game that fluctuates the second special symbol B2 in response to the winning of the game ball to the second start winning device 22, and the result of the second symbol variation game is displayed. As a result, the display results of the big hit, the small hit and the loss are displayed. For example, when the result of the second symbol variation game is a big hit, at the end of the second symbol variation game, symbols indicating 18 numbers from “1.” to “18.” are displayed as the second special symbol B2. The When the result of the second symbol variation game is a small hit, a symbol indicating a number “0” is displayed as the second special symbol B2 at the end of the second symbol variation game. In the present embodiment, for convenience of explanation, the second special symbol B2 is shown as “... (Dot)”. Further, when the result of the second symbol variation game is lost, at the end of the second symbol variation game, a symbol “-” indicating a loss is displayed as the second special symbol B2 (see FIG. 2). The second special symbol B2 is a symbol that does not make sense (a symbol that is not a letter or a number).

  Here, the special symbols B1 and B2 displayed in the case of a big hit are made up of a probability variation symbol and a non-probability variation symbol. The probability variation symbol is a first probability variation state in which the probability that a jackpot is derived in the first symbol variation game has a high probability, or a second probability that the probability that the jackpot is derived in the second symbol variation game varies with a high probability. It is a symbol used as an opportunity to start a fluctuation state.

The number of second start reserved balls is “+1” by winning a game ball to the second start winning device 22, and is “−1” by starting the second variable game.

  As shown in FIGS. 1 and 2, a normal symbol display device 53 having a visible display unit is disposed on the lower right side of the center accessory 60. In this normal symbol display device 53, a normal symbol variation game that fluctuates the normal symbol G1 is executed in response to the passing of the game ball to the gate 25, and the normal symbol variation result is displayed as a result of the random symbol lottery. The symbol G1 is stopped and displayed. In addition, the normal symbol G1 of the present embodiment is of two types: a winning symbol “◯” or a lost symbol “X”. When the winning symbol is derived (when the normal symbol variation game is won), the normal electric accessory solenoid SOL1 is driven for a predetermined time, and the pair of blade members 21b are opened.

  As shown in FIG. 2 and the like, a normal symbol holding display device F is disposed below the normal symbol display device 53.

  As shown in FIG. 1, an effect button 15 a is provided on the upper surface of the upper ball tray 15. In other words, the effect button 15a is arranged on the surface side of the pachinko machine 10 that can be reached by the player. The effect button 15a is operated by the player in order to execute a notice indicating that the result of the first symbol variation game or the second symbol variation game may be a big hit. The effect button 15a is turned on when operated by the player, and outputs an operation signal to the overall control CPU 32a (see FIG. 3) of the overall control board 32. Further, the effect button 15a is turned off when not being operated by the player, and does not output an operation signal. The effect button 15a may be provided at other places such as the back side of the ashtray 20 and the operation handle 19.

  As shown in FIG. 1 and FIG. 2, in a region between the second start winning device 22 and the big winning device 23, a failure nail group 80 that is a “winning prevention member” is disposed. The obstacle nail group 80 is composed of a plurality of obstacle nails 82 arranged in a straight line along the height direction of the game board 13. These obstacle nails 82 are the same nails as the game nails 81. The distance between adjacent obstacle nails 82 is set to be slightly smaller than the diameter of the game ball, and in this embodiment is set to about 0.8 times the diameter of the game ball (11 mm). Further, the distance between the obstacle nail 82 located on the uppermost side among the obstacle nails 82 and the center accessory 60 is also set smaller than the diameter of the game ball. Further, the distance between the lowermost obstacle nail 82 among the respective obstacle nails 82 and the decorative member 83 provided at the lower right portion of the game area is also set smaller than the diameter of the game ball. With the above configuration, the game ball cannot pass between the left region of the obstacle nail group 80 and the right region of the obstacle nail group 80. Therefore, the obstacle nail group 80 can prevent the game ball launched aiming at the second start winning device 22 from winning the big winning device 23 as it is.

  As shown in FIG. 4, a main ROM 31b and a main RAM 31c are electrically connected to the main CPU 31a. The main CPU 31a uses a hit determination random number, a first jackpot symbol random number, a second jackpot symbol random number, a reach determination random number, a first variation pattern distribution random number used in various lotteries relating to the first variation game and the second variation game. The values of various random numbers such as the second variation pattern distribution random numbers are updated every predetermined period. Then, the main CPU 31a sets the updated value in the random number storage area of the main RAM 31c and rewrites the value before the update. Various flags that are appropriately rewritten during the operation of the pachinko machine 10 are stored (set) in the flag storage area of the main RAM 31c. In the timer storage area of the main RAM 31c, various timers that are appropriately rewritten during the operation of the pachinko machine 10 are stored (set). Further, in the reserved ball storage area of the main RAM 31c, the first start reserved ball, the second start reserved ball and the normal symbol reserved ball are stored. That is, the main RAM 31c has a function as “hold storage means”.

  The hit determination random number is used when determining whether or not the first variable game is a big hit (when determining the first big hit) and when determining whether or not the second variable game is a big hit (when determining the second big hit) ) Is a random number used. Further, the random number for hit determination is used when determining whether or not the first variable game is a small hit when the result of the first variable game is lost (at the time of the first small hit determination), and for the second variable game This is a random number used when determining whether or not the second variable game is a small hit when the result is lost (when determining the second small hit). The first jackpot symbol random number is a random number used when determining the first special symbol B1 when the result of the first variation game is a jackpot, and the second jackpot symbol random number is the result of the second variation game. Is a random number used when determining the second special symbol B2 in the case of a big hit. The reach determination random number is used when deciding whether or not to execute the reach effect when the result of the first variation game is lost (during the first reach determination), and when the result of the second variation game is lost. In this case, the random number is used when determining whether or not to execute the reach effect (when determining the second reach). The first variation pattern distribution random number is a random number used when determining the variation pattern for specifying the effect time and the content of the effect in the first variation game. The second variation pattern distribution random number is the first variation pattern distribution random number. It is a random number used when determining the variation pattern for specifying the effect time and effect contents of the game effect in the two-variable game.

  The main ROM 31b shown in FIG. 4 stores two variation pattern groups 1 and 2 (see FIG. 5) to which variation patterns for the first symbol variation game (first symbol combination game) are distributed. . That is, the main ROM 31b has a function as “variation pattern group storage means”. Note that the variation pattern for the first symbol variation game is such that the symbols (first effect symbol E1) in each column displayed on the first effect symbol display unit 71 start to change (start the first symbol combination game). This is for specifying the production time and production contents of the game production (display production, light production production, audio production) from when the symbols in all the rows are stopped (the first symbol combination game is finished). In addition, the variation pattern for the first symbol variation game is distributed with the first variation pattern distribution random number values (100 integers of 0 to 99 in this embodiment).

  The variation pattern group 1 includes a first variation pattern distribution table 1A (see FIG. 6A), a first variation pattern distribution table 1B (see FIG. 6B), and a first variation pattern distribution table 1C (see FIG. 6). 6 (c)).

The variation pattern P3 is a pattern that is a base for a small hit effect that displays a small hit symbol combination (a symbol combination in which the left symbol, the right symbol, and the middle symbol all stop at the same symbol) without undergoing a reach effect. Yes. The variation pattern P4 indicates a pattern that is a base for the jackpot effect that displays the jackpot symbol combination (the symbol symbol combination in which the middle symbol stops at the same symbol as the left symbol and the right symbol) through the reach effect. The reach effect refers to an effect in which, after the middle symbol is changed in a state where the left symbol and the right symbol are stopped with the same symbol, the symbol combination is stopped and the symbol combination is derived. Note that the fluctuation time (185 seconds) specified by the fluctuation pattern P4 is longer by five seconds than the fluctuation time (180 seconds) specified by the fluctuation pattern P2. More specifically, the jackpot effect specified by the fluctuation pattern P4 and the loss reach effect specified by the fluctuation pattern P2 are equal in the effect contents and the effect time until the symbol combination of the big hit or the loss is derived. Yes. However, in the big hit effect, since the lottery is performed after the symbol combination is derived, the effect time (fluctuation time) is longer by 5 seconds than the case of the lost reach effect.

  In the first variation pattern distribution table 1B (see FIG. 6B), variation patterns for the first symbol combination game in the first probability variation state are distributed. Specifically, the first variation pattern distribution table 1B includes a variation pattern P5 for a loss effect, a variation pattern P6 for a loss reach effect, a variation pattern P7 for a small hit effect, and a variation for a big hit effect.

Note that the fluctuation time (185 seconds) specified by the fluctuation pattern P8 is longer by five seconds than the fluctuation time (180 seconds) specified by the fluctuation pattern P6. More specifically, the jackpot effect specified by the fluctuation pattern P8 and the loss reach effect specified by the fluctuation pattern P6 are the same as the effect contents and the presentation time until the symbol combination of the big hit or the loss is derived. Yes. However, in the big hit effect, since the lottery is performed after the symbol combination is derived, the effect time (fluctuation time) is longer by 5 seconds than the case of the lost reach effect.

  In the first variation pattern distribution table 1C (see FIG. 6C), variation patterns for the first symbol combination game in the variation time reduction state are distributed. The variation time shortening state is a state in which the variation time of the first special symbol B1 in the first symbol variation game is shortened.

The variation pattern P11 indicates a pattern that is a base for a small hit effect that displays a small symbol combination without a reach effect. The variation pattern P12 indicates a pattern that is a base of a jackpot effect that displays a jackpot symbol combination through a reach effect. Note that the fluctuation time (95 seconds) specified by the fluctuation pattern P12 is longer by five seconds than the fluctuation time (90 seconds) specified by the fluctuation pattern P10. More specifically, the jackpot effect specified by the variation pattern P12 and the loss reach effect specified by the variation pattern P10 have the same effect content and effect time before the jackpot or lose symbol combination is derived. Yes. However, in the big hit effect, since the lottery is performed after the symbol combination is derived, the effect time (fluctuation time) is longer by 5 seconds than the case of the lost reach effect.

  On the other hand, the variation pattern group 2 shown in FIG. 5 includes the first variation pattern distribution table 2A (see FIG. 6D), the first variation pattern distribution table 2B (see FIG. 6E), and the first variation.

The variation pattern P15 indicates a pattern that is a base of a small hit effect that displays a small hit symbol combination without a reach effect. The variation pattern P16 indicates a pattern that is a base of the jackpot effect that displays the jackpot symbol combination through the reach effect. Note that the fluctuation time (60 seconds) specified by the fluctuation pattern P16 is longer by five seconds than the fluctuation time (55 seconds) specified by the fluctuation pattern P14. More specifically, the jackpot effect specified by the variation pattern P16 and the loss reach effect specified by the variation pattern P14 have the same effect content and effect time before the jackpot or lose symbol combination is derived. Yes. However, in the big hit effect, since the lottery is performed after the symbol combination is derived, the effect time (fluctuation time) is longer by 5 seconds than the case of the lost reach effect.

  In the first variation pattern distribution table 2B (see FIG. 6E), variation patterns for the first symbol combination game in the first probability variation state are distributed. Specifically, the first variation pattern distribution table 2B includes a variation pattern P17 for a loss effect, a variation pattern P18 for a loss reach effect, a variation pattern P19 for a small hit effect, and a variation for a big hit effect.

The variation pattern P18 indicates a pattern that is a base of the lose reach effect that displays the lose symbol combination through the reach effect. The variation pattern P19 shows a pattern that is a base of a small hit effect that displays a small hit symbol combination without going through a reach effect. The variation pattern P20 indicates a pattern that is a base of a jackpot effect that displays a jackpot symbol combination through a reach effect. Note that the fluctuation time (60 seconds) specified by the fluctuation pattern P20 is longer by five seconds than the fluctuation time (55 seconds) specified by the fluctuation pattern P18. More specifically, the jackpot effect specified by the variation pattern P20 and the loss reach effect specified by the variation pattern P18 have the same effect content and effect time before the jackpot or lose symbol combination is derived. Yes. However, in the big hit effect, since the lottery is performed after the symbol combination is derived, the effect time (fluctuation time) is longer by 5 seconds than the case of the lost reach effect.

  In the first variation pattern distribution table 2C (see FIG. 6 (f)), variation patterns for the first symbol combination game in the variation time reduction state are distributed. Specifically, the first variation pattern distribution table 2C includes a variation pattern P21 for a loss effect, a variation pattern P22 for a loss reach effect, a variation pattern P23 for a small hit effect, and a variation for a big hit effect.

The variation pattern P22 indicates a pattern that is a base of the lose reach effect that displays the lost symbol combination through the reach effect. The variation pattern P23 indicates a pattern that is a base for a small hit effect that displays a small symbol combination without a reach effect. The variation pattern P24 indicates a pattern that is a base for a jackpot effect that displays a jackpot symbol combination through a reach effect. The fluctuation time (35 seconds) specified by the fluctuation pattern P24 is longer by five seconds than the fluctuation time (30 seconds) specified by the fluctuation pattern P22. More specifically, the jackpot effect specified by the variation pattern P24 and the loss reach effect specified by the variation pattern P22 are equal to the effect contents and the effect time until the symbol combination of the big hit or the loss is derived. Yes. However, in the big hit effect, since the lottery is performed after the symbol combination is derived, the effect time (fluctuation time) is longer by 5 seconds than the case of the lost reach effect.

  As shown in FIG. 5, the variation pattern group 1 is assigned with a variation pattern in which the probability that the advance notice is executed is relatively high and various effects are performed. On the other hand, the variation pattern group 2 is assigned with a variation pattern in which the probability that a notice is executed is relatively low and a simple and light effect is performed.

  The variation time of the game effect specified by the variation pattern is different for each variation pattern group 1 and 2. More specifically, the variation pattern group 1 is a variation pattern group in which the variation time of the game effect is relatively long, and the variation pattern group 2 is a variation pattern group in which the variation time of the game effect is relatively short.

  More specifically, in the variation pattern P1 to P4 and P13 to P16 for the first symbol combination game in the normal state, the variation time (180 seconds) of the game effect specified by the variation pattern P2 for the lose-reach effect is It is set longer than the change time (55 seconds) of the game effect specified by the change pattern P14 for the lose reach effect. The variation time (12 seconds) of the game effect specified by the variation pattern P3 for the small hit effect is set longer than the variation time (10 seconds) of the game effect specified by the variation pattern P15 for the small hit effect. Yes. The variation time (185 seconds) of the game effect specified by the variation pattern P4 for the big hit effect is set longer than the variation time (60 seconds) of the game effect specified by the variation pattern P16 for the big hit effect. Note that the game effect change time (5 seconds) specified by the lose effect change pattern P1 is equal to the game effect change time (5 seconds) specified by the lose effect change pattern P13.

  Also, in the variation patterns P5 to P8 and P17 to P20 for the first symbol combination game in the first probability variation state, the variation time (180 seconds) of the game effect specified by the variation pattern P6 for the lost reach effect is It is set longer than the change time (55 seconds) of the game effect specified by the change pattern P18 for the lose reach effect. The variation time (12 seconds) of the game effect specified by the variation pattern P7 for the small hit effect is set longer than the variation time (10 seconds) of the game effect specified by the variation pattern P19 for the small hit effect. Yes. The variation time (185 seconds) of the game effect identified by the variation pattern P8 for the big hit effect is set longer than the variation time (60 seconds) of the game effect identified by the variation pattern P20 for the big hit effect. The game effect change time (5 seconds) specified by the lose effect change pattern P5 is equal to the game effect change time (5 seconds) specified by the lose effect change pattern P17.

  Furthermore, in the variation patterns P9 to P12 and P21 to P24 for the first symbol combination game in the variation time shortening state, the variation time (90 seconds) of the game effect specified by the variation pattern P10 for the lose reach effect is a loss. It is set longer than the variation time (30 seconds) of the game effect specified by the variation pattern P22 for reach effect. The variation time (8 seconds) of the game effect specified by the variation pattern P11 for the small hit effect is set longer than the variation time (6 seconds) of the game effect specified by the variation pattern P23 for the small hit effect. Yes. The variation time (95 seconds) of the game effect specified by the variation pattern P12 for jackpot effect is set longer than the variation time (35 seconds) of the game effect specified by the variation pattern P24 for jackpot effect. Note that the game effect change time (5 seconds) specified by the lose effect change pattern P9 is equal to the game effect change time (5 seconds) specified by the lose effect change pattern P21.

  Accordingly, the variation pattern group 1 should be selected when the player wants to enjoy the game effect thoroughly or when the game machine has a relatively small number of winnings (starting winnings) to the first start winning device 21. It is a variation pattern group. The variation pattern group 2 is a variation pattern group to be selected when a player requests a short game effect or when the player has a relatively large number of start winnings.

  Further, the main ROM 31b shown in FIG. 4 stores a second variation pattern distribution table (see FIG. 7) in which variation patterns for the second symbol variation game (second symbol combination game) are allocated. In the second variation pattern distribution table of the present embodiment, a variation pattern P25 for a lost reach effect, a variation pattern P26 for a small hit effect, and a variation pattern P27 for a big hit effect are distributed. In addition, each variation pattern P25-P27 is all columns after the symbol (second effect symbol E2) of each column displayed on the second effect symbol display unit 72 starts changing (starts the second symbol combination game). This is for specifying the production time and production contents of the game production until this symbol is stopped (the second symbol combination game is ended). Each variation pattern P25 to P27 is assigned a second variation pattern distribution random number value (100 integers from 0 to 99 in this embodiment). Note that the variation pattern P25 indicates a pattern serving as a base for the lost reach effect that displays the lost symbol combination through the reach effect. The variation pattern P26 for a small hit effect indicates a pattern that is a base for the small hit effect that displays the combination of symbols for the small hit without passing through the reach effect. The variation pattern P27 indicates a pattern that is a base of a jackpot effect that displays a jackpot symbol combination through a reach effect.

  In addition, the production time (fluctuation time) of the lose reach production, the small hit production, and the big hit production is different for each of the fluctuation patterns P25 to P27. Specifically, the lose reach effect is executed for 20 seconds based on the fluctuation pattern P25, the small hit effect is executed for 12 seconds based on the fluctuation pattern P26, and the big hit effect is executed for 25 seconds based on the fluctuation pattern P27. It has become. In addition, among the variation patterns P1 to P24 determined at the start of the first symbol variation game, the variation time (5 seconds) of the game effect specified by the variation patterns P13, P17, and P21 for the loss effect is the shortest. Yes. The game effect change time (12 seconds in the present embodiment) specified by the small hit effect change pattern P26 determined at the start of the second symbol change game is the lose effect change pattern P13, P17, It is set longer than the variation time of the game effect specified by P21. The fluctuation time (25 seconds) specified by the fluctuation pattern P27 is longer by five seconds than the fluctuation time (20 seconds) specified by the fluctuation pattern P25. More specifically, the jackpot effect specified by the variation pattern P27 and the loss reach effect specified by the variation pattern P25 are equal to the effect contents and the effect time until the symbol combination of the big hit or the loss is derived. Yes. However, in the big hit effect, since the lottery is performed after the symbol combination is derived, the effect time (fluctuation time) is longer by 5 seconds than the case of the lost reach effect.

  Next, various processes related to the first symbol variation game and the second symbol variation game executed by the main CPU 31a shown in FIGS. 3 and 4 (first big hit determination, second big hit determination, first small hit determination, second Small hit determination, first reach determination, second reach determination, determination of big hit symbol, lost symbol, variation pattern, etc.) will be described. The main ROM 31b includes programs used for the various processes described above (a first jackpot determination program, a first jackpot gaming state grant program, a second jackpot judgment program, a second jackpot game state grant program, a jackpot judgment program, A winning game state giving program and a variation pattern determining program) are stored.

  First, the main CPU 31a determines whether the input winning signal is the first winning signal from the first starting port switch SE1 or the second winning signal from the second starting port switch SE2. When it is determined that the input winning signal is the first winning signal, the main CPU 31a performs control to execute the first symbol variation game. More specifically, the main CPU 31a acquires from the main RAM 31c the value of the first big hit symbol random number extracted by random lottery and updated every predetermined period, and stores the acquired value in the random number storage area of the main RAM 31c. Store (memorize). On the other hand, when it is determined that the input winning signal is the second winning signal, the main CPU 31a performs control to execute the second symbol variation game independently of the first symbol variation game. More specifically, the main CPU 31a acquires from the main RAM 31c the value of the second big hit symbol random number extracted by random number lottery and updated every predetermined cycle, and stores the acquired value in the random number storage area of the main RAM 31c. Store (memorize). Further, the main CPU 31a acquires, from the main RAM 31c, the value of a random number for hit determination extracted by random number lottery and updated every predetermined period when the start winning condition is satisfied, and the obtained value is a random number in the main RAM 31c. Store (store) in the storage area.

  The first big hit determination program is a program for causing the main CPU 31a shown in FIGS. 3 and 4 to function as “first big hit determination means”. That is, the main CPU 31a determines whether or not the result of the first symbol variation game (first variation game) is a big hit when it is determined that the input winning signal is the first winning signal. It has become. More specifically, the main CPU 31a compares the value of the random number for hit determination stored in the random number storage area of the main RAM 31c with the first big hit determination value stored in the main ROM 31b immediately before the start of the first variation game. Then, the first big hit determination (win lottery) for determining whether or not the first variable game is successful is performed. In the present embodiment, the numerical values that can be taken by the random numbers for hit determination are set to 0 to 599 (all 600 kinds of integers). Then, the main CPU 31a uses the two first big hit judgment values from among the numerical values that can be taken as the random numbers for the hit judgment, and sets the lottery probability for the big hit to 2/600 (= 1 / 300≈0.3%). First hit determination is performed.

  The second jackpot determination program is a program for causing the main CPU 31a shown in FIGS. 3 and 4 to function as “second jackpot determination means”. That is, the main CPU 31a determines whether or not the result of the second symbol variation game (second variation game) is a big hit when it is determined that the input winning signal is the second winning signal. It has become. Specifically, the main CPU 31a compares the value of the random number for hit determination stored in the random number storage area of the main RAM 31c with the second big hit determination value stored in the main ROM 31b immediately before the start of the second variable game. Then, the second big hit determination (win lottery) for determining whether or not the second variable game is successful is performed. Then, the main CPU 31a uses two second jackpot determination values from among the numerical values that can be taken as random numbers for hit determination, and sets the lottery probability for jackpot to 2/600 (= 1 / 300≈0.3%). The second big hit determination is performed. That is, the main CPU 31a performs the big hit determination with the same lottery probability regardless of whether the game is the first variation game or the second variation game.

  The main CPU 31a shown in FIG. 3 and FIG. 4 is the case where the second start holding ball is not stored in the main RAM 31c and the first start holding ball is stored in the main RAM 31c. The first big hit determination is performed based on the start holding ball. On the other hand, if the second start hold ball is stored in the main RAM 31c, the main CPU 31a is based on the second start hold ball regardless of whether or not the first start hold ball is stored in the main RAM 31c. The second jackpot determination is performed. In other words, the main CPU 31a preferentially executes the second symbol variation game when both the first start hold ball and the second start hold ball are stored in the main RAM 31c.

  Then, the main CPU 31a determines that the result of the first symbol variation game is a small hit when the result of the first big hit determination is lost (when the value of the random number for hit determination does not match the first big hit determination value). Whether or not to be determined. More specifically, the main CPU 31a compares the value of the hit determination random number stored in the random number storage area of the main RAM 31c with the first small hit determination value stored in the main ROM 31b to determine whether or not the small hit is correct. The first small hit determination is performed. More specifically, when the currently selected variation pattern group is variation pattern group 1, the main CPU 31a uses six first small hit determination values from among the numerical values that the hit determination random number can take. Thus, the first small hit determination is performed with the lottery probability per small hit being 6/600 (= 1/100 = 1%). Further, when the currently selected variation pattern group is variation pattern group 2, the main CPU 31a uses two first small hit determination values from among the numerical values that the random number for hit determination can take. The first small hit determination is performed with a lottery probability of 2/600 (= 1 / 300≈0.3%).

  The small hit determination program is a program for causing the main CPU 31a shown in FIGS. 3 and 4 to function as “small hit determination means”. That is, the main CPU 31a determines that the result of the second symbol variation game is a small hit when the determination result by the second big hit determination is lost (when the random number for hit determination and the second big hit determination value do not match). It is determined whether or not. More specifically, the main CPU 31a compares the value of the random number for hit determination stored in the random number storage area of the main RAM 31c with the second small hit determination value stored in the main ROM 31b to determine whether or not the hit is small. The second small hit determination is performed. Then, the main CPU 31a uses the 580 second small hit determination values out of the numerical values that can be taken as the random numbers for hit determination, and sets the lottery probability for the small hit to 580/600 (= 1 / 1.03≈97 %), The second small hit determination is performed. That is, in most cases, the main CPU 31a determines that the result of the second symbol variation game is a small hit. That is, the main CPU 31a makes a small hit determination with different lottery probabilities for the first symbol variation game and the second symbol variation game. Therefore, the probability (97%) that the result of the second symbol variation game is a small hit is the probability (1.0% or 0.3%) that the result of the first symbol variation game is a small hit, and the first It is set higher than the probability (0.3%) that the results of the symbol variation game and the second symbol variation game are big hits.

  The main CPU 31a shown in FIG. 3 and FIG. 4 stores the value of the reach determination random number read from the main RAM 31c and the first ROM stored in the main ROM 31b when the determination result by the first small hit determination is lost. A first reach determination is made as to whether or not to execute the lose reach by comparing with the reach determination value. Similarly, the main CPU 31a compares the reach determination random number read from the main RAM 31c with the second reach determination value stored in the main ROM 31b when the determination result of the second small hit determination is lost. Then, the second reach determination is made as to whether or not to execute the lose reach. In the present embodiment, since the determination results of all the second reach determinations are affirmative (the reach determination random number value matches the second reach determination value), the main CPU 31a executes the lose reach in all cases. Judge that.

  On the other hand, when the determination result of the first big hit determination is affirmative (the value of the random number for hit determination matches the first big hit determination value), the main CPU 31a shown in FIGS. 3 and 4 determines the big hit. Similarly, when the determination result of the second big hit determination is affirmative (the value of the random number for hit determination matches the second big hit determination value), the main CPU 31a determines the big hit.

  When the determination result by the first big hit determination is a big hit, the main CPU 31a performs the first step related to the stop symbol (first effect symbol E1) derived from the first symbol combination game on the first effect symbol display unit 71. One special symbol B1 is determined. Specifically, the main CPU 31a, based on the value of the first jackpot symbol random number stored in the random number storage area of the main RAM 31c, the first special symbol indicating any one of "1" to "18" B1 is determined. When the determination result by the first small hit determination is a small hit, the main CPU 31a determines the first special symbol B1 indicating “0” as the small hit symbol. Further, when the determination result of the first small hit determination is lost or lost, the main CPU 31a determines the symbol “−” which is a lost symbol as the first special symbol B1.

  Also, the main CPU 31a shown in FIGS. 3 and 4 determines whether the first special symbol B1 is a probability variable symbol or not based on the value of the first big hit symbol random number stored in the random number storage area of the main RAM 31c. It is determined whether it is. In the present embodiment, the first big hit symbol random numbers are “1”, “3”, “5”, “7”, “9”, “11”, “13”, “15”, “17”. If it is either, it is determined that the first special symbol B1 is a probable variation symbol, and the values of the first big hit symbol random numbers are “2”, “4”, “6”, “8”, “10”, “ If any of “12”, “14”, “16”, and “18”, it is determined that the first special symbol B1 is a non-probable variable symbol.

  The main CPU 31a gives the first probability variation state in the first symbol variation game started after the end of the first jackpot gaming state when it is determined that the first special symbol B1 is the probability variation symbol. It has become. Furthermore, when the first special symbol B1 is determined to be a non-probable variation symbol, the main CPU 31a gives a variation time reduction state in the first symbol variation game started after the end of the first big hit gaming state. It has become. The variation time reduction state may be continued until the next first big hit game state is started, or the symbol variation display is executed a plurality of times (for example, 100 times). It may be continued for a while. Thereafter, when the provision of the variation time shortening state is completed, the main CPU 31a imparts the normal state.

  When the first probability variation state is given in the first symbol variation game, the main CPU 31a shown in FIG. 3 and FIG. The first jackpot determination is performed with the jackpot lottery probability set to 20/600 (= 1 / 30≈3.3%). That is, the number of first jackpot determination values in the first probability variation state is ten times that in the first probability variation state. The first probability variation state may be continued until the next first big hit game state is started, and the symbol variation display is performed a plurality of times (for example, 10,000 times). It may be continued until it is done.

More specifically, the main CPU 31a indicates a second value indicating any one of “1.” to “18.” based on the value of the second jackpot symbol random number stored in the random number storage area of the main RAM 31c. The special symbol B2 is determined. When the determination result by the second small hit determination is a small hit, the main CPU 31a determines the second special symbol B2 indicating “0.” as the small hit symbol. Furthermore, when the determination result by the second big hit determination is a lose reach, the main CPU 31a determines the symbol “-” which is a lose symbol as the second special symbol B2.

  Also, the main CPU 31a shown in FIGS. 3 and 4 determines whether the second special symbol B2 is a probability variable symbol or not based on the value of the second big hit symbol random number stored in the random number storage area of the main RAM 31c. It is determined whether it is. In the present embodiment, the second big hit symbol random number value is “1”, “3”, “5”, “7”, “9”, “11”, “13”, “15”, “17”. If it is either, it is determined that the second special symbol B2 is a probability variation symbol, and the second big hit symbol random number value is “2”, “4”, “6”, “8”, “10”, “ If any one of “12”, “14”, “16”, and “18”, it is determined that the second special symbol B2 is a non-probable variable symbol.

  Further, the main CPU 31a gives the second probability variation state in the second symbol variation game started after the end of the second big hit gaming state when it is determined that the second special symbol B2 is the probability variation symbol. It has become. The probability that the second probability variation state is given when the result of the second symbol variation game is a big hit is the probability that the first probability variation state is given when the result of the first symbol variation game is a big hit. Are set to be the same.

  When the second probability variation state is given in the second symbol variation game, the main CPU 31a shown in FIGS. 3 and 4 displays the 20 second big hit judgment values from among the numbers that can be taken as the random numbers for the hit judgment. The second jackpot determination is performed with the lottery probability of jackpot being 20/600 (= 1 / 30≈3.3%). That is, the number of second jackpot determination values in the second probability variation state is ten times that in the second probability variation state. It should be noted that the second probability variation state may be continued until the next second big hit game state) is started, and the symbol variation display may be performed a plurality of times (for example, 10,000 times). It may be continued until it is executed.

  The variation pattern determination program is a program for causing the main CPU 31a to function as “variation pattern determination means”. That is, the main CPU 31a determines a variation pattern from different variation pattern tables when the first symbol variation game is executed and when the second symbol variation game is executed. Further, the main CPU 31a determines a variation pattern from different variation pattern distribution tables when the variation pattern group 1 is selected and when the variation pattern group 2 is selected.

The control command set here is output in the next command output process (see step MC2 in FIG. 9). Further, the main CPU 31a subtracts the special symbol 1 timer or the special symbol 2 timer set at the start of fluctuation every interrupt (4 ms). When the special symbol 1 timer reaches 0 ms, the main CPU 31a sets (outputs) the first symbol stop command that instructs the stop of the first special symbol B1 and the first effect symbol E1 as a control command. When the special symbol 2 timer reaches 0 ms, the main CPU 31a sets (outputs) a second symbol stop command for instructing the stop of the second special symbol B2 and the second effect symbol E2 as a control command.

  The main CPU 31a shown in FIGS. 3 and 4 reads a read signal (INT signal or an instruction signal) to instruct the overall control board 32 to read a control command constituting the control signal in accordance with the output timing of the control signal. , The strobe signal) is output via the output port 35 and the output buffer 36.

  The first jackpot gaming state granting program is a program for causing the main CPU 31a to function as “first jackpot gaming state granting means”. That is, the main CPU 31a gives the first big hit game state in which the big winning device 23 is in the open state for the big hit when the determination result by the first big hit determination becomes the big hit. In the first big hit game state, one opening effect, a plurality of times (in this embodiment, two times or fifteen times) round effect and one ending effect are executed. The opening effect is executed when the big winning device 23 is in the closed state and when the first big hit gaming state is started. Each round effect is executed when the special winning device 23 is switched from the closed state to the open state by the exciting action of the special winning opening solenoid SOL2. The round effect per time is executed between the time when the special winning device 23 is switched to the open state and the switch to the closed state. In addition, the ending effect is when the grand prize winning device 23 is switched from the open state to the closed state, and when the first big hit gaming state is ended (in this embodiment, the end of the second or fifteenth round effect). When).

  When the determination result by the first jackpot determination is a big hit (that is, when it is determined that the result of the first symbol variation game is a big hit), the main CPU 31a shown in FIGS. The number of executions (number of rounds) is set. Specifically, the main CPU 31a determines whether to set the number of rounds to “15” or “2” based on the value of the first big hit symbol random number stored in the random number storage area of the main RAM 31c. Make a round decision. When the value of the random number for the first jackpot symbol is “1” to “6”, “8” to “13”, or “15” to “18”, the main CPU 31a specially drives the round number “15”. It is stored in the main RAM 31c as the maximum number of continuous operations of the accessory 1. On the other hand, when the value of the random number for the first big hit symbol is “7” or “14”, the main CPU 31a stores the round number “2” in the main RAM 31c as the maximum value 1 of the number of continuous operation of the special electric accessory.

  Then, after the first symbol stop command is output, the main CPU 31a shown in FIGS. 3 and 4 generates an opening designation command 1 for instructing the start of the opening effect, and outputs it as a control command. Next, the main CPU 31a instructs the start of the first to fifteenth round effects when the maximum value 1 of the special electric accessory continuous operation number stored in the main RAM 31c indicates the number of rounds “15”. The round designation command 1 to be output is sequentially output as a control command. Further, the main CPU 31a instructs the start of the first and second round effects when the maximum number 1 of the special electric accessory continuous operation number stored in the main RAM 31c indicates the number of rounds “2”. The round designation command 1 is sequentially output as a control command. Thereafter, the main CPU 31a outputs an ending designation command 1 for instructing the start of the ending effect as a control command.

  Note that the first big hit gaming state of the present embodiment is one of so-called “15R probability change”, “15R short time change”, and “2R probability change”. Here, “15R probability change” is a state in which the first probability variation state is given after 15 round effects are executed in the first big hit gaming state. The “15R short time” is a state in which a fluctuating time reduction state is given after 15 round effects are executed in the first big hit gaming state. The “2R probability variation” is a state in which a first probability variation state is given after two round effects are executed in the first jackpot gaming state.

  The second big hit game state granting program is a program for causing the main CPU 31a shown in FIGS. 3 and 4 to function as “second big hit game state giving means”. That is, the main CPU 31a gives the second big hit game state in which the big winning device 23 is in the open state for the big hit when the determination result by the second big hit determination becomes the big hit. In the second big hit gaming state, one opening effect, one round effect, and one ending effect are executed. The opening effect is executed when the big winning device 23 is in the closed state and the second big hit gaming state is started. The round effect is executed when the special winning device 23 is switched from the closed state to the open state by the exciting action of the special winning opening solenoid SOL2. The round effect is executed after the grand prize winning device 23 is switched to the open state until it is switched to the closed state. In addition, the ending effect is executed when the big winning device 23 is switched from the open state to the closed state, and when the second big hit gaming state is ended (in the present embodiment, at the end of the round effect). It is like that. In this embodiment, the number of rounds in the second jackpot gaming state (“1”) is smaller than the number of rounds in the first jackpot gaming state (“15”). The time for the device 23 to be in the open state is set to be shorter than the time for the big prize winning device 23 to be in the open state when the first big hit gaming state is given.

  Then, after the second symbol stop command is output, the main CPU 31a shown in FIGS. 3 and 4 generates the opening designation command 2 instructing the start of the opening effect, and outputs it as a control command. Next, the main CPU 31a outputs a round designation command 2 for instructing start of a round effect as a control command. Thereafter, the main CPU 31a outputs an ending designation command 2 for instructing the start of the ending effect as a control command.

  Further, the main CPU 31a gives the first small hit game state in which the big winning opening door 23a of the big winning device 23 is opened for the small hit when the determination result by the first small hit determination becomes the small hit. It is like that. It should be noted that the production content in the first small hit gaming state is the same as the production content in the big hit (“2R probability variation”) to which the first probability variation state is given after the two round productions are executed. Specifically, in the first small hit game state, one small hitting opening effect, two small hitting round effects, and one small hitting ending effect are executed. The small hitting opening effect is executed when the first small hitting gaming state is started. The first small hitting round effect is executed after the end of the small hitting opening effect, and the second small hitting round effect is executed after the end of the first small hitting round effect. . The small hitting ending effect is executed when the first small hitting game state is ended (in the present embodiment, at the end of the second small hitting round effect). Therefore, when the first small hit game state is executed, the player cannot determine whether the result of the first symbol variation game is a small hit or a big hit.

  In addition, as described above, in the first small hit game state, the effect (small effect for small hits) in which the large winning opening door 23a is switched from the closed state to the open state to the closed state by the exciting action of the large winning port solenoid SOL2 is 2. To be executed once. That is, the movement of the big winning door 23a in the first small hit gaming state is the big winning mouth in the big hit ("2R probability change") to which the first probability variation state is given after the two round effects are executed. This is the same as the movement of the door 23a. For this reason, when the big winning opening door 23a is opened and closed twice, the player cannot determine whether the result of the first symbol variation game is a small hit or a big hit.

  From the above, the main CPU 31a shown in FIGS. 3 and 4 executes a concealment effect that conceals the first probability variation state for a predetermined period when the result of the first symbol variation game is a small hit or a big hit. It can be said that That is, the main CPU 31a has a function as “secret display effect execution means”.

  Note that the probability that a concealment effect appears based on the variation pattern for the big hit effect and the variation pattern for the small hit effect differs for each of the variation pattern groups 1 and 2. Specifically, the probability that the secret effect appears based on the variation patterns P4, P8, P12 for the jackpot effect distributed to the variation pattern group 1 is the variation pattern for the jackpot effect distributed to the variation pattern group 2 Based on P16, P20, and P24, it is larger than the probability that the secret effect appears. That is, when the variation patterns P4, P8, and P12 are determined, the variation values P16, P20, and P24 determine the value of the first big hit symbol random number (“7” or “14”) that becomes the number of rounds “2”. In this case, the number is larger than the value of the first big hit symbol random number (“7”) which becomes the number of rounds “2”. Further, the probability that the secret effect appears based on the variation patterns P3, P7, P11 for the small hit effect distributed to the variation pattern group 1 is the variation pattern P15 for the small hit effect distributed to the variation pattern group 2. Based on P19 and P23, it is larger than the probability that the secret effect appears. Note that the probability that the concealment effect appears based on the variation pattern for the small hit effect is equal to the probability that the variation pattern for the small hit effect is determined. Accordingly, the number (6) of hit determination random numbers assigned to the variation patterns P3, P7, P11 is larger than the number of hit determination random numbers (1) assigned to the variation patterns P15, P19, P23. .

  The small hit game state giving program is a program for causing the main CPU 31a shown in FIGS. 3 and 4 to function as “small hit game state giving means”. That is, the main CPU 31a gives the second small hit game state in which the big winning device 23 is in the open state for the small hit when the determination result by the second small hit determination becomes the small hit. In the second small hit game state, the effect that the special winning opening door 23a is switched from the closed state to the open state to the closed state by the exciting action of the special winning opening solenoid SOL2 is executed once. In this embodiment, the number of rounds in the second small hit gaming state (“1”) is smaller than the number of rounds in the first big hit gaming state (“15”). The time for the big winning device 23 to be in the open state is set shorter than the time for the big winning device 23 to be in the open state when the first big hit gaming state is given.

(2-2) Electrical Configuration of Overall Control Board 32 As shown in FIG. 3, the overall control board 32 includes an overall control CPU 32a. The overall control CPU 32a includes an overall ROM (not shown) and an overall RAM (not shown). ) Is connected. In addition, an effect button 15a is electrically connected to the overall control CPU 32a. The overall control CPU 32a updates the values of various random numbers used for determining the game effect at predetermined intervals. Then, the overall control CPU 32a rewrites the value before update by setting the updated value in the setting area of the overall RAM. For example, the random number storage area of the general RAM stores a random number for lost left symbol, a random number for lost symbol, a random number for lost right symbol, a random number for notice distribution, and the like. Various flags that are appropriately rewritten during operation of the pachinko machine 10 are stored (set) in the flag storage area of the overall RAM. Various timers that are appropriately rewritten during operation of the pachinko machine 10 are stored (set) in the timer storage area of the overall RAM.

  The general ROM stores a notice pattern distribution table (see FIG. 8) in which a plurality of notice patterns YP1 to YP4 serving as a notice base are distributed. Each notice pattern YP1 to YP4 is associated with the contents of the notice for each notice pattern YP1 to YP4. More specifically, the notice pattern YP1 causes the character C1 (red robot in the present embodiment) to appear on the symbol display device 61, and displays the character “reach” on the symbol display device 61, thereby achieving reach. The pattern that is the base of the reach notice to be notified is shown. The notice pattern YP2 is displayed by causing the symbol display device 61 to display characters in the order of character C1 → character C2 (copper-colored robot in the present embodiment) and displaying the character “reach confirmed” on the symbol display device 61. , A pattern serving as a base for a reach confirmation notice for notifying reach confirmation. That is, the advance notice based on the advance notice pattern YP2 is a step-up advance notice in which the effects develop in the order of the character C1 → the character C2. The notice pattern YP3 is a base of the big hit notice for notifying the big hit by causing the character C3 (a silver robot in the present embodiment) to appear on the symbol display device 61 and displaying the characters “hit” on the symbol display device 61. Shows the pattern. The notice pattern YP4 appears on the symbol display device 61 in the order of character C3 → character C4 (golden robot in the present embodiment), and displays the character “definite jackpot” on the symbol display device 61. A pattern serving as a base for the jackpot confirmation notice for notifying the confirmation of the jackpot is shown. That is, the advance notice based on the advance notice pattern YP4 is a step-up advance notice in which the effects develop in the order of the character C3 → the character C4. In addition, the notice patterns YP1 to YP4 are assigned random numbers for notice distribution (50 integers from 0 to 49 in this embodiment).

  Note that the probability that the notice appears based on the variation pattern differs for each of the variation pattern groups 1 and 2. Specifically, the probability that a notice will appear based on the variation patterns P1 to P12 assigned to the variation pattern group 1 having a relatively long variation time of the game effect is a variation in which the variation time of the game effect is relatively short. Based on the variation patterns P13 to P24 distributed to the pattern group 2, it is set to be larger than the probability that the notice appears. That is, when the variation patterns P1 to P12 are determined, the value of the random number for distribution to be assigned to the advance notice patterns YP1 to YP4 is the advance notice to be assigned to the advance notice patterns YP1 to YP4 when the change patterns P13 to P24 are determined. It is larger than the random number for distribution.

  In addition, the probability that the notice appears based on the variation pattern for the lost reach effect and the variation pattern for the jackpot effect differs for each of the variation pattern groups 1 and 2. More specifically, the probability that a notice will appear based on the variation patterns P2, P6, P10 for losing reach directed to the variation pattern group 1 is the variation for the losing reach directed to the variation pattern group 2. Based on the patterns P14, P18, and P22, it is larger than the probability that the notice appears. That is, when the variation patterns P2, P6, and P10 are determined, the values of the random numbers for distribution to the notification patterns YP1 to YP4 are the notification patterns YP1 to YP4 when the variation patterns P14, P18, and P22 are determined. It is larger than the value of the random number for notice distribution that is distributed to. Further, the probability that a notice appears based on the variation patterns P4, P8, P12 for the jackpot effect distributed to the variation pattern group 1 is the variation patterns P16, P20, P24 for the jackpot effect distributed to the variation pattern group 2. Is greater than the probability that a notice will appear. That is, when the variation patterns P4, P8, and P12 are determined, the values of the random numbers for distribution to the notification patterns YP1 to YP4 are the notification patterns YP1 to YP4 when the variation patterns P16, P20, and P24 are determined. It is larger than the value of the random number for notice distribution that is distributed to.

  Incidentally, when a variation pattern designation command is input, the overall control CPU 32a shown in FIG. 3 stores the variation pattern designated by the variation pattern designation command in the overall RAM. When a special symbol designation command is input, the overall control CPU 32a stores the first special symbol B1 or the second special symbol B2 designated by the special symbol designation command in the overall RAM. Further, the overall control CPU 32a confirms the symbol variation time corresponding to the variation pattern stored in the overall RAM, and sets (temporarily stores) the symbol variation time in the overall RAM as a changing timer. The overall control CPU 32a starts subtraction of the symbol variation time stored as the variation timer. At this time, the symbol variation time is subtracted every predetermined interrupt period (4 ms).

  Further, the overall control CPU 32a shown in FIG. 3 is first stopped and displayed on the first effect symbol display section 71 at the end of the first symbol combination game based on the first special symbol B1 stored in the overall RAM. The production design E1 is generated. For example, when the first special symbol B1 stored in the overall RAM is any one of “1” to “18”, the variation pattern stored in the overall RAM is the variation pattern P4, P8, P12 for jackpot effect. , P16, P20, P24. When the first special symbol B1 stored in the overall RAM is “0”, the variation pattern stored in the overall RAM is the variation pattern P3, P7, P11, P15, P19, P23 for the small hit effect. It becomes one of these. In these cases, the overall control CPU 32a generates the first effect symbol E1 (the effect symbol left, middle, and right) that is finally stopped by the first effect symbol display unit 71 so that all columns are of the same type. To do. More specifically, the overall control CPU 32a generates the effect symbol left, the effect symbol in the effect symbol, and the effect symbol right (the effect symbols are of the same type) based on the first special symbol B1. For example, if the first special symbol B1 is “1” or “2”, the first effect symbol E1 is “1”, and if the first special symbol B1 is “3” or “4”, the first effect symbol E1. Is “2”. The generated first effect symbol E1 (effect symbol left, middle, right) is derived to the first effect symbol display unit 71 as a final symbol combination. Then, the overall control CPU 32a stores data corresponding to the produced effect symbol left, the effect symbol, and the effect symbol right in the overall RAM.

  Further, the overall control CPU 32a shown in FIG. 3 is stopped and displayed on the second effect symbol display section 72 at the end of the second symbol combination game based on the second special symbol B2 stored in the overall RAM. The production design E2 is generated. For example, when the second special symbol B2 stored in the overall RAM is any one of “1.” to “18.”, the variation pattern stored in the overall RAM is the variation pattern P27 for jackpot effect. . Further, when the second special symbol B2 stored in the overall RAM is “0.”, the variation pattern stored in the overall RAM is the variation pattern P26 for the small hit effect. In these cases, the overall control CPU 32a generates the second effect symbol E2 (effect symbol left, middle, and right) that is finally stopped by the second effect symbol display unit 72 so that all the columns are of the same type. To do. More specifically, the overall control CPU 32a generates an effect symbol left, an effect symbol, and an effect symbol right (each effect symbol is the same type) based on the second special symbol B2. For example, if the second special symbol B2 is “1.” or “2.”, the second effect symbol E2 is “1”, and if the second special symbol B2 is “3.” or “4.” 2. The effect design E2 is “2”. The generated second effect symbol E2 (effect symbol left, middle, right) is derived to the second effect symbol display unit 72 as a final symbol combination. Then, the overall control CPU 32a stores data corresponding to the produced effect symbol left, the effect symbol, and the effect symbol right in the overall RAM.

  The first special symbol B1 or the second special symbol B2 stored in the overall RAM is “−”, and the variation pattern stored in the overall RAM is the variation pattern P2, P6, P10, P14 for lost reach production. , P18, P22, and P25, the overall control CPU 32a shown in FIG. 3 determines the loss reach. In this case, the overall control CPU 32a determines the effect symbols left, middle, and right so that the left column and the right column are the same type of symbols, and the middle column is a different type of symbols from the left and right columns. Specifically, the effect symbol left and the effect symbol right (both effect symbols are of the same type) are generated on the basis of the random number value for the lost symbol. Then, the inside of the effect symbol is generated based on the value of the random symbol for lost symbol. If the value of the random symbol for losing pattern and the random number value for the losing left symbol (or the random number value for the losing right symbol) match, the overall control CPU 32a determines that the effect symbol in the effect symbol and the effect symbol left (or the effect symbol right). ) Are generated so that they do not match. Then, the overall control CPU 32a stores data corresponding to the produced effect symbol left, the effect symbol, and the effect symbol right in the overall RAM. In the present embodiment, the numbers that can be taken by random numbers for the left symbol for lost, the random number for right for lost, and the random number for lost symbol are 10 integers from 0 to 9, and one numerical value corresponds to each type of symbol. It is attached.

  The first special symbol B1 stored in the overall RAM is “−”, and the variation pattern stored in the overall RAM is any one of the variation patterns P1, P5, P9, P13, P17, and P21 for losing effects. In the case of one, the overall control CPU 32a shown in FIG. 3 determines a loss. In this case, the overall control CPU 32a generates effect symbols left, middle, and right so that all columns do not become the same type of symbols. Specifically, the production symbol left is generated based on the value of the random symbol for the loss left symbol, the production symbol is generated based on the value of the random number for the middle symbol of the loss, and the production is produced based on the value of the random number for the loss right symbol. Generate the symbol right. If the value of the lost symbol random number and the value of the lost right symbol random match, the overall control CPU 32a generates the effect symbol right so that the effect symbol left does not match the effect symbol right. Then, the overall control CPU 32a stores data corresponding to the produced effect symbol left, the effect symbol, and the effect symbol right in the overall RAM.

  The overall control CPU 32a uses, as control commands, a change pattern designation command for designating a change pattern stored in the overall RAM as a control command, and the voice / lamp control of the voice / lamp control board 34. The data is output to the CPU 34a. As a result, the specific content of the game effect executed by the display control board 33 and the sound / lamp control board 34 is comprehensively controlled by the overall control board 32.

  Further, the overall control CPU 32a shown in FIG. 3 outputs an effect symbol left designation command for designating the effect symbol left of the first effect symbol E1 or the second effect symbol E2 to the display control CPU 33a as a control command. Similarly, the overall control CPU 32a displays an effect symbol right designation command for designating the effect symbol right of the first effect symbol E1 or the second effect symbol E2, and the effect symbol of the first effect symbol E1 or the second effect symbol E2. The specified design symbol designation command is output to the display control CPU 33a as a control command.

  Thereafter, the overall control CPU 32a subtracts the changing timer stored in the overall RAM every interrupt (4 ms). Further, the overall control CPU 32a determines whether or not the changing timer has reached 0 ms. When it is determined that the changing timer has reached 0 ms, the overall control CPU 32a ends the subtraction of the changing timer. On the other hand, if it is determined that the changing timer is not 0 ms, the overall control CPU 32a determines whether or not the effect button 15a is operated during the first symbol changing game or the second symbol changing game, that is, the first symbol. It is determined whether or not an operation signal is input from the effect button 15a during the variation game or during the second symbol variation game.

  When it is determined that an operation signal is input from the effect button 15a, the overall control CPU 32a illustrated in FIG. 3 performs control to execute a notice. More specifically, the overall control CPU 32a determines which of the notice patterns YP1 to YP4 from the notice pattern distribution table based on the value of the notice distribution random number acquired from the general RAM when it is determined that the operation signal is input. Or one. Then, the overall control CPU 32a stores the determined notice pattern in the overall RAM. Furthermore, the overall control CPU 32a outputs a notice pattern designation command for designating the decided notice pattern to the display control CPU 33a and the sound / lamp control CPU 34a as a control command.

  Thereafter, when the first symbol stop command or the second symbol stop command is input from the main CPU 31a, the overall control CPU 32a uses the input first symbol stop command or the second symbol stop command as a control command to the display control CPU 33a and Output to the voice / lamp control CPU 34a.

  When the opening designation command 1 is inputted from the main CPU 31a, the overall control CPU 32a shown in FIG. 3 outputs the inputted opening designation command 1 to the display control CPU 33a and the sound / lamp control CPU 34a as control commands. Next, when the round designation command 1 for the first to fifteenth round effects or the first and second round effects is inputted from the main CPU 31a, the overall control CPU 32a changes the inputted round designation command 1 to The control command is output to the display control CPU 33a and the sound / lamp control CPU 34a. Thereafter, when the ending designation command 1 is inputted from the main CPU 31a, the overall control CPU 32a outputs the inputted ending designation command 1 to the display control CPU 33a and the sound / lamp control CPU 34a as control commands.

  Similarly, when the opening designation command 2 is inputted from the main CPU 31a, the overall control CPU 32a shown in FIG. 3 outputs the inputted opening designation command 2 to the display control CPU 33a and the sound / lamp control CPU 34a as control commands. . Next, when the round designation command 2 for round effect is inputted from the main CPU 31a, the overall control CPU 32a outputs the inputted round designation command 2 to the display control CPU 33a and the sound / lamp control CPU 34a in order as control commands. To do. Thereafter, when the ending designation command 2 is inputted from the main CPU 31a, the overall control CPU 32a outputs the inputted ending designation command 2 to the display control CPU 33a and the sound / lamp control CPU 34a as control commands.

  The overall control CPU 32a uses the above control commands and the like as control signals (8-bit signals), and outputs the signals at a predetermined timing via an output port (not shown) and an output buffer (not shown). Further, the overall control CPU 32a, in accordance with the output timing of the control signal, instructs the display control board 33 and the sound / lamp control board 34 to read a control command constituting the control signal (INT signal or , A strobe signal) is output via an output port and an output buffer.

The display RAM temporarily stores (sets) various information that can be appropriately rewritten during the operation of the pachinko machine 10.

  The display ROM stores a plurality of types of display effect data used when the first symbol combination game or the second symbol combination game is performed. The display effect data is information for the display control CPU 33a to control display contents (such as symbol variation) of the first effect symbol display unit 71 and the second effect symbol display unit 72, that is, the first effect symbol display unit 71. And information for instructing the second effect symbol display unit 72 to execute the display effect.

Each round effect display effect data is stored in association with each of the first to fifteenth round effects. The display effect data for ending effects is stored in association with the ending effects. The display effect data for opening effect, the display effect data for round effect, and the display effect data for ending effect are displayed on the first effect symbol display unit 71 and the second effect symbol display unit 72 by the display control CPU 33a shown in FIG. This is information for instructing the execution of the effect, the first to fifteenth round effects, and the ending effect.

  The display ROM stores secret effect display effect data used for a secret effect when the result of the first symbol variation game is a small hit. The display effect data for concealment effect is information for the display control CPU 33a to instruct the symbol display device 61 to execute the concealment effect.

  When a variation pattern designation command is input from the overall control CPU 32a, the display control CPU 33a stores the variation pattern designated by the variation pattern designation command in the display RAM. Further, when an effect symbol left designation command is input from the overall control CPU 32a, the display control CPU 33a stores the effect symbol left designated by the command in the display RAM.

The display control CPU 33a stores the notice pattern designated by the notice pattern designation command in the display RAM when the notice pattern designation command is input from the overall control CPU 32a.

  After that, when the first symbol stop command is input from the overall control CPU 32a shown in FIG. 3, the display control CPU 33a is based on the effect symbols left, right, and middle that are input at the start of variation and stored in the display RAM. The first effect symbol display unit 71 is instructed to stop the first effect symbol E1. Thereby, the designated first effect symbol E1 is stopped and displayed on the first effect symbol display unit 71. Further, when the second symbol stop command is input from the overall control CPU 32a, the display control CPU 33a displays the second effect symbol display based on the effect symbols left, right, and middle that are input at the start of variation and stored in the display RAM. The unit 72 is instructed to stop the second effect symbol E2. Thereby, the designated second effect symbol E2 is stopped and displayed on the second effect symbol display unit 72.

  When a variation pattern designation command is input, the display control CPU 33a sets (generates) any one of a plurality of types of display effect data stored in the display ROM, and displays the set display effect data. The data is stored in a RAM storage area. Thereby, the display control CPU 33a performs display control based on the variation pattern designation command and the display effect data. More specifically, the display control CPU 33a converts the display effect data stored in the display RAM into a symbol signal and outputs it to the first effect symbol display unit 71 or the second effect symbol display unit 72. As a result, the first effect symbol display unit 71 or the second effect symbol display unit 72 can perform a predetermined display (such as a first symbol combination game or a second symbol combination game) based on the symbol signal.

Display effect data is stored in a storage area of the display RAM. As a result, the display control CPU 33a performs display control based on the notice pattern designation command and the notice display effect data. More specifically, the display control CPU 33a converts the display effect data for notice stored in the display RAM into a notice signal and outputs it to the symbol display device 61. As a result, the symbol display device 61 can perform a predetermined display (notice) based on the notice signal.

Are stored in the storage area of the display RAM. Accordingly, the display control CPU 33a performs display control based on the opening designation command 1 or the opening designation command 2 and the display effect data for opening effect. More specifically, the display control CPU 33a converts the display effect data for opening effects stored in the display RAM into a symbol signal and outputs the symbol signal to the symbol display device 61. As a result, the symbol display device 61 can perform a predetermined display based on the symbol signal.

As a result, the frame lamps 16a to 16c and the speakers 17a to 17c can perform predetermined light emission and audio output based on the light emission control signal and the audio signal.

  Next, processing (timer interrupt processing) performed by the main CPU 31a of the main control board 31 will be described. A program for performing this process is repeatedly executed at predetermined interrupt intervals (every 4 ms) in the main CPU 31a after the pachinko machine 10 is started.

  In step MC1 shown in FIG. 9, the main CPU 31a executes an output process for outputting a control signal to the ordinary electric accessory solenoid SOL1, a special prize opening solenoid SOL2, etc., and proceeds to the process of step MC2.

  In the process of step MD2 (special symbol input process), the main CPU 31a executes a subroutine shown in FIG. The subroutine of FIG. 11 includes the processes of steps S1 to S8. In step S1, the main CPU 31a determines whether or not a game ball has won the first start winning device 21 (that is, whether or not a first win signal has been input from the first start port switch SE1). When the game ball has not won the first start winning device 21 (step S1: N), the main CPU 31a proceeds to the process of step S5 without performing the processes of steps S2 to S4. On the other hand, when a game ball wins the first start winning device 21 (step S1: Y), the main CPU 31a proceeds to the process of step S2.

  In step S <b> 2, the main CPU 31 a determines whether or not the first start-reserved number of balls stored in the main RAM 31 c is less than 4. When the first start reserved ball number is “4” (step S2: N), the main CPU 31a proceeds to the process of step S5 without performing the processes of steps S3 and S4. On the other hand, when the first start reserved ball number is less than 4 (step S2: Y), the main CPU 31a proceeds to the process of step S3.

  In step S3, the main CPU 31a adds 1 to the first start-reserved ball number stored in the main RAM 31c, and proceeds to the process in step S4. In step S4, the main CPU 31a acquires the hit determination random number and the first big hit symbol random number and stores them in the random number storage area of the main RAM 31c. Then, the main CPU 31a proceeds to the process of step S5.

  In step S5, the main CPU 31a determines whether or not a game ball has won the second start winning device 22 (that is, whether or not a second win signal has been input from the second start port switch SE2). When the game ball has not won the second start winning device 22 (step S5: N), the main CPU 31a ends this subroutine without performing the processing of steps S6 to S8. On the other hand, when the game ball has won the second start winning device 22 (step S5: Y), the main CPU 31a proceeds to the process of step S6.

  In step S <b> 6, the main CPU 31 a determines whether or not the second number of starting reserved balls stored in the main RAM 31 c is less than 4. When the number of the second starting reserved balls is “4” (step S6: N), the main CPU 31a ends the present subroutine without performing the processes of steps S7 and S8. On the other hand, when the number of second starting reserved balls is less than 4 (step S6: Y), the main CPU 31a proceeds to the process of step S7.

In step S8, the main CPU 31a acquires the hit determination random number and the second big hit symbol random number, and stores them in the random number storage area of the main RAM 31c. Then, the main CPU 31a ends this subroutine.

  When the subroutine shown in FIG. 11 ends, the main CPU 31a proceeds to the process of step MD3 shown in FIG. In the process of step MD3 (special electric accessory input process), the main CPU 31a executes a subroutine shown in FIG. The subroutine of FIG. 12 includes the processes of steps S10 to S15. In step S10, the main CPU 31a determines whether or not a game ball has won the big winning device 23 (whether or not a detection signal has been input from the count switch SE3). When the game ball has not won the big winning device 23 (step S10: N), the main CPU 31a ends this subroutine without performing the processing of steps S11 to S15. On the other hand, when a game ball wins the big winning device 23 (step S10: Y), the main CPU 31a proceeds to the process of step S11. In step S11, the main CPU 31a reads the system flag from the main RAM 31c in order to confirm the contents of the system flag. The system flag indicates whether or not the big hit gaming state (first big hit gaming state or second big hit gaming state) or the small hit gaming state (first small hit gaming state or second small hit gaming state) is being executed. Flag. Note that “01H” is set as the system flag (stored in the main RAM 31c) when the big hit gaming state is set, and “02H” (stored in the main RAM 31c) is set as the system flag when the small hit gaming state is set. ) Is set, and when neither the big hit gaming state nor the small hit gaming state is set, “00H” is set (stored in the main RAM 31c) as a system flag.

  In the following step S12, the main CPU 31a determines whether or not “01H” is set as the system flag read in step S11 (that is, whether or not the big hit gaming state is in effect). When “01H” is set as the system flag (step S12: Y), the main CPU 31a proceeds to the process of step S13. In step S13, the main CPU 31a adds 1 to the number of winning a prize opening because a winning of a game ball is detected while the big winning device 23 is opened (step S10). In addition, the number of winning a prize winning mouth is the number of game balls won in the big winning device 23 during one round production in the big hit gaming state or during the opening of one big winning device 23 in the small hit gaming state. Shows the number. Then, the main CPU 31a ends this subroutine.

  In step S12, when “01H” is not set as the system flag read in step S11 (step S12: N), the main CPU 31a proceeds to the process of step S14. In step S14, the main CPU 31a determines whether or not “02H” is set as the system flag read in step S11 (that is, whether or not it is in the small hit gaming state). When “02H” is set as the system flag (step S14: Y), the main CPU 31a proceeds to the process of step S13.

  In step S14, when “02H” is not set as the system flag read in step S11 (step S14: N), the game is performed with the count switch SE3 of the big winning device 23 when neither the big hit gaming state nor the small hit gaming state is set. Since the winning of the ball has been detected, the main CPU 31a determines that the winning is an illegal winning, and proceeds to the processing of step S15. In step S15, the main CPU 31a sets, in the main RAM 31c, an error designation command for notifying the hall computer, the store clerk of the game store, and the player that the prize is illegal. The error designation command set in the main RAM 31c is controlled by the hall computer and the overall control by the output processing (see step MC1 in FIG. 9) and the command output processing (see step MC2 in FIG. 9) of the next timer interrupt processing. The data is output to the overall control CPU 32a of the board 32. When the error control command is input, the overall control CPU 32a outputs the command to the voice / lamp control CPU 34a of the voice / lamp control board 34, and the frame lamps 16a to 16c and the speaker indicating that the prize is illegal. Control to notify at 17a to 17c is performed. Then, the main CPU 31a ends this subroutine.

  When the subroutine shown in FIG. 12 is finished, the main CPU 31a finishes the subroutine shown in FIG. 10, and proceeds to the processing of step MC4 shown in FIG. In step MC4, the main CPU 31a executes random number processing for updating various random numbers such as a hit determination random number, a first big hit symbol random number, and a second big hit symbol random number, and proceeds to the process of step MC5.

  In the process of step MC5 (special symbol start process), the main CPU 31a executes a subroutine shown in FIGS. The subroutine of FIGS. 13 and 14 includes the processes of steps S40 to S61. In step S40, the main CPU 31a reads the second start reserved ball number from the main RAM 31c in order to confirm the second start reserved ball number, and proceeds to the process of step S41. In step S41, the main CPU 31a determines whether or not the second number of starting reserved balls read in step S40 is greater than zero. If the second start-up ball number is 0 (step S41: N), the main CPU 31a proceeds to the process of step S51. On the other hand, when the number of second starting reserved balls is larger than 0 (step S41: Y), the main CPU 31a proceeds to the process of step S42.

  In step S42, the main CPU 31a updates the second starting reserved ball number stored in the main RAM 31c by decrementing by 1, and proceeds to the process of step S43. In step S43, the main CPU 31a reads the hit determination random number corresponding to “1” of the second starting reserved ball number acquired by the special symbol input process (see FIG. 11) and stored in the main RAM 31c. In step S43, when the winning determination random number corresponding to the second starting reserved ball number “1” is read, the main CPU 31a sets the second hit determining random number corresponding to the second starting reserved ball number “2” to the second number. It is updated to a random number for hit determination corresponding to “1” of the number of reserved balls for starting. Further, the main CPU 31a obtains the second starting reserved ball number obtained by subtracting 1 (for example, “4” → “3”, “3” → “2”) from the random number for hit determination corresponding to each second starting reserved ball number. Update to the corresponding hit judgment random number.

  In subsequent step S44, the main CPU 31a determines whether or not the hit determination random number read in step S43 matches the second jackpot determination value (executes the second jackpot determination). Further, the main CPU 31a confirms the contents of the probability variation flag 2, and when the probability variation flag 2 is “01H”, the main CPU 31a executes the second big hit determination based on the 20 second big hit determination values, and the probability variation When the flag 2 is “00H”, the second big hit determination is executed based on the two second big hit determination values. The probability variation flag 2 indicates whether or not the second probability variation state is given as the gaming state. When the second probability variation state is assigned, “01H” is set as the probability variation flag 2, and when the second probability variation state is not assigned, “00H” is set as the probability variation flag 2. .

  When the hit determination random number matches the second big hit determination value (step S44: Y), that is, when the big hit is determined, the main CPU 31a proceeds to the process of step S45. On the other hand, if the hit determination random number does not match the second big hit determination value (step S44: N), the main CPU 31a proceeds to the process of step S46. In step S46, the main CPU 31a determines whether or not the hit determination random number read in step S43 matches the second small hit determination value (executes the second small hit determination). The main CPU 31a executes the second small hit determination based on 580 second small hit determination values.

  When the hit determination random number matches the second small hit determination value (step S46: Y), that is, when the small hit is determined, the main CPU 31a proceeds to the process of step S47. On the other hand, when the hit determination random number does not match the second small hit determination value (step S46: N), that is, when the loss is determined, the main CPU 31a proceeds to the process of step S48, which is a process related to the loss.

In step S57, the main CPU 31a determines whether or not the hit determination random number read in step S54 matches the first small hit determination value (executes the first small hit determination). When the currently selected variation pattern group is variation pattern group 1, the main CPU 31a executes the first small hit determination based on the six first small hit determination values. Further, when the currently selected variation pattern group is the variation pattern group 2, the main CPU 31a executes the first small hit determination based on the two first small hit determination values.

  When the hit determination random number matches the first small hit determination value (step S57: Y), that is, when the small hit is determined, the main CPU 31a proceeds to the process of step S58. On the other hand, when the hit determination random number does not match the first small hit determination value (step S57: N), that is, when the loss is determined, the main CPU 31a proceeds to the process of step S59, which is a process related to the loss.

  In the process of step S56 (special symbol 1 big hit fluctuation setting process), the main CPU 31a executes a subroutine shown in FIG. The subroutine of FIG. 19 includes the processes of steps S100 to S105. In step S100, the main CPU 31a acquires “1” as the number of first starting reserved balls acquired by the special symbol input process (see FIG. 11) and stored in the main RAM 31c in order to confirm the first big hit symbol random number. The first big hit symbol random number corresponding to is read. In step S100, when the main CPU 31a reads the first big hit symbol random number corresponding to the first start reserved ball number “1”, the first big hit symbol corresponding to the first start reserved ball number “2”. The random number for use is updated to the first big hit design random number corresponding to “1” of the first starting reserved ball number. In addition, the main CPU 31a subtracts 1 from the first big hit symbol random number corresponding to each first start reserved ball (for example, “4” → “3”, “3” → “2”). The first big hit symbol random number corresponding to the number is updated.

  In the following step S101, the main CPU 31a selects the first special symbol B1 based on the first big hit symbol random number read in step S100, and proceeds to the processing in step S102. In step S102, the main CPU 31a stores (sets) the first special symbol B1 selected in step S101 in the main RAM 31c, and proceeds to the processing in step S103.

  In step S103, the main CPU 31a stores the maximum value 1 of the number of continuous operations of the special electric accessory and the special electric accessory preliminary timer 1 in the main RAM 31c. The maximum value 1 of the number of continuous operations of the special electric accessory is the number of rounds (“15” or “2”) in which the round effect is performed in the first big hit gaming state. The special electric accessory preliminary timer 1 indicates an opening time (25000 ms) for opening the special winning device 23.

  In subsequent step S104, the main CPU 31a determines a variation pattern distribution table for the special symbol 1. More specifically, the main CPU 31a determines which of the variation pattern groups 1 and 2 is the currently selected variation pattern group, and then determines the first variation pattern distribution tables 1A to 1C and 2A to 2C (FIG. 6). The first variation pattern distribution table is determined. In step S105, the main CPU 31a executes a variation pattern determination process 1. In the variation pattern determination process 1, the main CPU 31a determines the variation pattern of the first variation game to be executed. Details of the variation pattern determination process 1 will be described later. Thereafter, the main CPU 31a ends this subroutine, and proceeds to the process of step S60 shown in FIG.

  In step S58 (special symbol small hit variation setting process), the main CPU 31a executes a subroutine shown in FIG. The subroutine in FIG. 21 includes the processes of steps S110 to S114. In step S110, the main CPU 31a determines the small hit symbol indicating the small hit as the first special symbol B1, and proceeds to the processing of step S111. In step S111, the main CPU 31a stores the small hit symbol (first special symbol B1) determined in step S110 in the main RAM 31c, and proceeds to the processing in step S112. In the present embodiment, a symbol indicating “0” is defined as the small hit symbol, and the first special symbol B1 indicating “0” is stored.

  In step S112, the main CPU 31a stores the maximum value 1 for the number of continuous operations of the special electric accessory and the special electric accessory preliminary timer 1 in the main RAM 31c. The maximum value 1 of the number of continuous operations of the special electric accessory means the number of times of opening (2 times) of the big winning device 23 in the first small hit gaming state. The special electric accessory preliminary timer 1 indicates an opening time (10000 ms) for opening the special winning device 23.

  In subsequent step S113, the main CPU 31a determines which of the variation pattern groups 1 and 2 is the currently selected variation pattern group, and then first variation pattern distribution tables 1A to 1C and 2A to 2C (FIG. 6)) is determined. In step S114, the main CPU 31a executes the variation pattern determination process 1. In the variation pattern determination process 1, the main CPU 31a determines the variation pattern of the first variation game to be executed. Details of the variation pattern determination process 1 will be described later. Then, after step S114 ends, the main CPU 31a ends this subroutine, and proceeds to the process of step S60 shown in FIG.

  In the process of step S59 (special symbol 1 loss variation setting process), the main CPU 31a executes a subroutine shown in FIG. The subroutine of FIG. 15 includes the processes of steps S80 to S84. In step S80, the main CPU 31a determines the lost symbol indicating the loss as the first special symbol B1, and proceeds to the process of step S81. In step S81, the main CPU 31a stores the lost symbol (first special symbol B1) determined in step S80 in the main RAM 31c. In the present embodiment, the symbol “-” is defined as the lost symbol, and the first special symbol B1 indicating the symbol “−” is stored.

  In subsequent step S82, the main CPU 31a acquires a reach determination random number, performs a first reach determination comparing the acquired reach determination random number with the first reach determination value, and proceeds to the process of step S83. In step S83, the main CPU 31a determines which of the variation pattern groups 1 and 2 is the currently selected variation pattern group, and then first variation pattern distribution tables 1A to 1C and 2A to 2C (FIG. 6). The first variation pattern distribution table is determined.

  In subsequent step S84, the main CPU 31a executes a variation pattern determination process 1. In the variation pattern determination process 1, the main CPU 31a determines the variation pattern of the first variation game to be executed. Details of the variation pattern determination process 1 will be described later. Then, after the end of step S84, the main CPU 31a ends this subroutine, and proceeds to the process of step S60 shown in FIG.

  In step S60, the main CPU 31a sets (sets) the variation time data corresponding to the variation pattern determined in any of step S56, step S58 and step S59 in the special symbol 1 timer stored in the main RAM 31c, The process proceeds to step S61. In step S61, the main CPU 31a sets a special symbol designation command for designating the first special symbol B1 determined in any of step S56, step S58, and step S59 in the main RAM 31c. The special symbol designation command set in the main RAM 31c in step S61 is output to the overall control CPU 32a of the overall control board 32 by the command output process (see step MC2 in FIG. 9) of the timer interrupt process from the next time. Then, the main CPU 31a ends this subroutine, and proceeds to the process of step MC6 of the timer interrupt process (see FIG. 9).

  In step MC6, the main CPU 31a performs first special electric accessory processing for controlling the opening and closing of the big winning door 23a of the big winning device 23 related to the first big hit gaming state and the first small hit gaming state, The second special electric accessory process for controlling the opening and closing of the big prize opening door 23a of the big prize winning device 23 related to the two big hit game state and the second small hit game state is executed, and the process proceeds to the process of step MC7. .

  In step MC7, the main CPU 31a executes the ordinary electric accessory process related to opening and closing of the pair of blade members 21b constituting the ordinary electric accessory. More specifically, the main CPU 31a proceeds to the process of step MC8 when the pair of blade members 21b are being opened. On the other hand, when the pair of blade members 21b are not being opened, the main CPU 31a executes various processes related to the opening and closing of the blade members 21b. For example, the main CPU 31a performs opening and closing of the pair of blade members 21b over a plurality of times. Specifically, the main CPU 31a sets information for opening the pair of blade members 21b and information indicating the number of times of opening and closing the pair of blade members 21b in the main RAM 31c. When the information for opening the pair of blade members 21b is set in the main RAM 31c, the main CPU 31a outputs a drive signal to the ordinary electric accessory solenoid SOL1 in the output process (step MC1) of the timer interrupt process. Is output to control the pair of blade members 21b to open. Also, the main CPU 31a opens a pair of blade members 21b and then a predetermined time elapses or until a predetermined number (10) of game balls wins the first start winning opening 21a. During this time, the pair of blade members 21b are controlled so as to maintain the open state. Then, the main CPU 31a sets information for closing the pair of blade members 21b in the main RAM 31c. Further, when the information for closing the pair of blade members 21b is set in the main RAM 31c, the main CPU 31a outputs a drive signal to the ordinary electric accessory solenoid SOL1 in the output process (step MC1) of the timer interrupt process. Is output to perform a control for closing the pair of blade members 21b. Then, the main CPU 31a proceeds to the process of step MC8.

  In step MC8, the main CPU 31a executes a special symbol variation process related to the first symbol variation game performed by the first special symbol display unit 51 and the second symbol variation game performed by the second special symbol display unit 52. Then, the process here ends.

  Next, the variation pattern determination process 1 executed in step S84 of the special symbol 1 loss variation setting process (see FIG. 15) and step S105 of the special symbol 1 big hit variation setting process (see FIG. 19) will be described.

  In step S140 shown in FIG. 17, the main CPU 31a acquires a first variation pattern distribution random number for determining a variation pattern. In step S141, the main CPU 31a, based on the first variation pattern distribution random number acquired in step S140, the variation pattern distribution table determined in step S83 of the special symbol 1 loss variation setting process (see FIG. 15), or Then, the variation pattern is determined from the variation pattern distribution table (see FIG. 6) determined in step S104 of the special symbol one big hit variation setting process (see FIG. 19). In subsequent step S142, the main CPU 31a stores (sets) the variation pattern determined in step S141 in the main RAM 31c as variation pattern number 1. That is, the main CPU 31a grasps the variation pattern of the first variation game by referring to the variation pattern number 1 when performing processing related to the execution of the first variation game.

  In subsequent step S143, the main CPU 31a sets a variation pattern designation command for designating the variation pattern set in step S142 in the main RAM 31c. Further, in step S143, information (flag or the like) corresponding to the variation pattern designation command set in the main RAM 31c, specifically, information indicating that the first special symbol display unit 51 variably displays the first special symbol B1. Is set in the main RAM 31c. Note that the variation pattern designation command set in step S143 includes information indicating that the first symbol combination game is to be executed by the first effect symbol display unit 71. The variation pattern designation command set in the main RAM 31c in step S143 is output to the overall control CPU 32a of the overall control board 32 by the command output process (see step MC2 in FIG. 9) of the timer interrupt process from the next time. Further, when the information indicating that the first special symbol B1 is variably displayed is set, the main CPU 31a outputs the first special symbol by the output processing (see step MC1 in FIG. 9) of the timer interruption processing from the next time. The fluctuation control for starting the fluctuation display of B1 is executed. Then, the main CPU 31a ends this subroutine.

  Next, the fluctuation pattern determination process 2 executed in step S94 of the special symbol 2 loss fluctuation setting process (see FIG. 16) and in step S125 of the special symbol 2 big hit fluctuation setting process (see FIG. 20) will be described.

  In step S145 shown in FIG. 18, the main CPU 31a acquires a second variation pattern distribution random number for determining a variation pattern. In step S146, the main CPU 31a performs step S93 of the special symbol 2 loss variation setting process (see FIG. 16) or the special symbol 2 big hit variation setting process based on the second variation pattern distribution random number acquired in step S145. A variation pattern is determined from the second variation pattern distribution table (see FIG. 7) determined in step S124 of FIG.

  In subsequent step S147, the main CPU 31a stores (sets) the variation pattern determined in step S146 in the main RAM 31c as the variation pattern number 2. That is, the main CPU 31a grasps the variation pattern of the second variation game by referring to the variation pattern number 2 when performing processing related to the execution of the second variation game.

  In subsequent step S148, the main CPU 31a sets a variation pattern designation command for designating the variation pattern set in step S147 in the main RAM 31c. Further, in step S148, information (flag or the like) corresponding to the variation pattern designation command set in the main RAM 31c, specifically, information indicating that the second special symbol display unit 52 variably displays the second special symbol B2. Is set in the main RAM 31c. Note that the variation pattern designation command set in step S148 includes information indicating that the game is a second symbol combination game to be executed by the second effect symbol display unit 72. Further, the variation pattern designation command set in the main RAM 31c in step S148 is output to the overall control CPU 32a of the overall control board 32 by the command output process (see step MC2 in FIG. 9) of the timer interrupt process from the next time. Further, when the information indicating that the second special symbol B2 is variably displayed is set, the main CPU 31a outputs the second special symbol by the output processing (see step MC1 in FIG. 9) of the timer interruption process after the next time. The fluctuation control for starting the fluctuation display of B2 is executed. Then, the main CPU 31a ends this subroutine.

  Next, a game procedure will be described.

  (A-1) First, the player launches (so-called left-handed) a game ball aiming at the first start winning device 21 (see <1> in FIG. 23). When the game ball wins the first start winning device 21, the first symbol variation game for varying the first special symbol B1 is started and the first symbol combination game for varying the first effect symbol E1 is started. The

  (A-2) However, because the player wants to know quickly whether or not the result of the first symbol variation game will be a big hit, seeking a symbol variation game in which the production time is short and the production contents are simplified. In spite of the fact that there is a case where there is a symbol variation game in which the production time is long and the production content is complicated. On the other hand, for the reason that the player wants to enjoy the symbol variation game carefully, although the presentation time is long and the content of the production is complicated, the effect time is shortened and the effect content is simplified. In some cases, a symbol variation game is played.

  In the above case, the player launches (so-called right-handed) a game ball aiming at the second start winning device 22 (see <2> in FIG. 23). When the game ball wins the second start winning device 22, a second symbol variation game for varying the second special symbol B2 is started, and a second symbol combination game for varying the second effect symbol E2 is started. The In this embodiment, the probability that the result of the second symbol variation game is a small hit is set to 580/600 (= 1 / 1.03). In other words, the second symbol variation game is a small hit in most cases.

  (A-3) Then, when the result of the second symbol variation game is a small hit, a second small hit gaming state in which the big winning device 23 is opened is given. In the second small hit game state, the effect that the large winning device 23 is switched to the open state for 1.7 seconds (= 1700 ms) is executed once.

  (A-4) After the end of the second small hit gaming state, if the currently selected variation pattern group is variation pattern group 1, the variation pattern group 2 is switched to, and the variation pattern group currently selected is variation pattern group. If it is 2, it switches to the fluctuation pattern group 1. Then, the fact that the change pattern group has been switched (in the present embodiment, the characters “game change!”) Is displayed on the symbol display device 61. Thereafter, the player switches to left-handed and performs a game (A-1) for starting the first symbol variation game.

  Next, a countermeasure when a right-handed (second symbol variation game) is started even though the first symbol variation game is not performed will be described.

  (B-1) When the player makes a right strike and the game ball wins the second start winning device 22, the second symbol variation game is executed, and in most cases, a small hit is made. Further, in the second small hit gaming state, an effect that the big winning device 23 is switched to the open state for 1.7 seconds (= 1700 ms) is executed once. Therefore, if the player always hits the right, the number of game balls increases and there is a risk of a big hit.

  Therefore, in the present embodiment, the obstacle nail group 80 (see FIG. 23 and the like) is disposed in the region between the second start winning device 22 and the big winning device 23. In this case, even if the small hits occur frequently and the big winning device 23 is switched to the open state, the game balls launched aiming at the second starting winning device 22 are made to win the big winning device 23 as they are. It is impossible. As a result, since it becomes difficult to win a prize ball by winning the game ball to the big prize device 23, the player does not make the first start prize device 21 win the game ball and the second start prize device 22 does not win the game ball. No longer have the idea of deliberately winning a prize.

  Furthermore, in this embodiment, the time when the result of the second symbol variation game becomes a big hit is larger than the opening time of the big winning device 23 when the result of the first symbol variation game becomes a big hit (25000 ms in this embodiment). The opening time of the winning device 23 (25000 ms in this embodiment) and the opening time of the big winning device 23 (1700 ms in this embodiment) when the result of the second symbol variation game is a small hit are set short. Further, in the present embodiment, the case where the result of the second symbol variation game is a jackpot than the number of times the big winning device 23 is opened (15 times in the present embodiment) when the result of the first symbol variation game is a jackpot. Decrease the number of times the big prize device 23 is released (one time in this embodiment) or the number of times the big prize device 23 is released (one time in this embodiment) when the result of the second symbol variation game is a small hit. ing. In this way, even if small hits occur frequently and the big winning device 23 is switched to the open state, the big winning device 23 is immediately switched to the closed state. It is extremely difficult to win a prize. As a result, since it becomes difficult to win a prize ball by winning the game ball to the big prize device 23, the player does not make the first start prize device 21 win the game ball and the second start prize device 22 does not win the game ball. No longer have the idea of deliberately winning a prize.

  Therefore, according to the present embodiment, the following effects can be obtained.

  (1) Conventionally, a technique for changing a game effect using effect changing means such as an effect button 15a has been proposed. However, since the effect button 15a is normally connected to the overall control CPU 32a, even if the effect button 15a is operated, the variation pattern determined by the main CPU 31a cannot be changed. That is, the effect button 15a can change the effect contents of the game effect, but cannot change the effect time of the game effect determined only by the variation pattern.

  Therefore, in the pachinko machine 10 according to the present embodiment, instead of changing the game effect using the effect button 15a, the player wins a game ball in the second start winning device 22 and obtains a small hit, thereby changing the variation pattern. The group is to be changed. For this reason, based on the variation pattern distributed to the changed variation pattern group, it is possible to start the first symbol variation game in which the production time and the production content are different from the current one. That is, compared with the case where only the effect contents are changed using the effect button 15a, the first symbol variation game more suited to the player's preference can be selected, so that the interest of the game can be sufficiently enhanced. Further, since the operation handle 19 used for launching the game ball can be used as it is for changing the variation pattern group, the change of the variation pattern group is facilitated. That is, when changing the variation pattern group, it is not necessary to perform troublesome work such as operating the effect button 15a.

  (2) In this embodiment, the variation pattern group is changed by using the second start winning device 22 used when starting the second symbol variation game. For this reason, it is not necessary to newly provide a changing means (such as a switch) for changing the variation pattern group in order to change the variation pattern group.

  (3) In this embodiment, the variation time (12 seconds) of the game effect specified by the variation pattern P26 for the small hit effect determined at the start of the second symbol variation game is the same as that at the start of the first symbol variation game. The variation time specified by the determined variation pattern is set longer than the shortest variation time (variation times identified by the variation patterns P13, P17, and P21: 5 seconds). As a result, since the digestion efficiency of the small hit effect is lowered, it is difficult for the big winning device 23 to be switched to the open state. Therefore, since it becomes difficult to win a prize ball by winning the game ball in the grand prize winning device 23, the player places the game ball in the second starting prize winning device 22 without causing the first starting prize winning device 21 to win a game ball. The idea of intentionally winning a prize is lost.

  (4) In the present embodiment, the main CPU 31a has a function of changing the variation pattern group, and the overall control CPU 32a has a function of determining a notice. For this reason, the process of any one of the main CPU 31a and the overall control CPU 32a is not excessively complicated. Further, the notice pattern designation command generated by the overall control CPU 32a is output to both the display control CPU 33a and the sound / lamp control CPU 34a. Therefore, it is possible to synchronize the advance notice executed by the symbol display device 61 and the advance notice made by the frame lamps 16a to 16c and the speakers 17a to 17c.

  (5) In the present embodiment, the hit determination random number is a random number used in common in the first symbol variation game and the second symbol variation game. In addition, the hit determination random number is commonly used for the big hit determination (when the first big hit is determined and the second big hit is determined) and the small hit is determined (when the first small hit is determined and when the second small hit is determined). It is a random number. From the above, since the types of random numbers can be reduced, the amount of data stored in the main RAM 31c can be reduced.

[Second Embodiment]
Next, the pachinko machine 10 of the second embodiment will be described in detail. Here, the description will focus on the parts that are different from the first embodiment, and the common parts will not be described in place of the same member numbers.

  In the present embodiment, the period during which the first probability variation state is given and the method for selecting the variation pattern group are different from those in the first embodiment. In other words, the first probability variation state is continued until five symbol variation displays are executed. Therefore, the pachinko machine 10 of the present embodiment is a so-called ST machine in which an upper limit is set for the number of times the probability variation state is continued. In the present embodiment, the main CPU 31a has six jackpot determination values (the first jackpot determination value or the first jackpot determination value or the first jackpot determination value) when the normal state is given in the symbol variation game (the first symbol variation game or the second symbol variation game). The big hit determination (the first big hit determination or the second big hit determination) is performed by setting the lottery probability of the big hit to 6/600 (= 1/100) using the 2 big hit determination value). In addition, when the probability variation state (the first probability variation state or the second probability variation state) is given in the symbol variation game, the main CPU 31a uses the 60 jackpot determination values to set the lottery probability for the jackpot to 600 minutes. Is determined to be 60 (= 1/10).

  Then, when starting the first symbol variation game to which the first probability variation state is given, the main CPU 31a changes the game effect regardless of whether or not the determination result by the second small hit determination is a small hit. The variation pattern group 1 having a relatively long time, that is, the first variation pattern distribution table 1B (see FIG. 6B) is always selected. Therefore, in the present embodiment, the first variation pattern distribution table 2B (see FIG. 6E) included in the variation pattern group 2 in the first embodiment is omitted.

  In the present embodiment, since the number of times of continuing the first probability variation state is only five, the game effect in the first symbol variation game is completed in a short time, resulting in a light effect. Therefore, in the present embodiment, when the first probability variation state is given, the variation pattern group 1 in which the variation time of the game effect is relatively long is always selected. As a result, even if the period during which the first probability variation state is given is short, it is possible to enjoy a symbol variation game in which the performance time is long and various game effects are performed. Therefore, even during the first probability fluctuation state, the interest of the game can be enhanced.

  In addition, you may change the said embodiment as follows.

  In the above embodiment, when the first big winning device and the second big winning gaming state and the second winning gaming state are given when the first big winning gaming state and the first small winning gaming state are given. The second grand prize-winning device that is in an open state may be provided separately. Further, the number of prize balls to be paid out when a game ball is awarded to the second big prize device may be set to be smaller than the number of prize balls to be paid out when the game ball is awarded to the first big prize device. In this way, even if game balls are awarded to the second grand prize winning device, it is not possible to increase the number of game balls so much, so the player can make the first start winning prize device 21 without winning the game balls. 2 The idea of intentionally winning the game ball in the start winning device 22 is lost.

  In the first embodiment, the first variation pattern distribution tables 1A and 2A used during the normal state and the first variation used during the first probability variation state for the variation pattern groups 1 and 2, respectively. The pattern distribution tables 1B and 2B and the first variation pattern distribution tables 1C and 2C used during the variation time reduction state were included. However, each variation pattern group only needs to include at least one first variation pattern distribution table. For example, when only one first variation pattern distribution table is included in the variation pattern group 1, the same is true regardless of whether the normal state, the first probability variation state, or the variation time reduction state is given. The variation pattern can be determined from the first variation pattern distribution table.

  Next, the technical ideas grasped by the embodiment described above are listed below.

  (1) In Claim 1, the first variation pattern group and the second variation pattern group are stored in the variation pattern group storage unit, and the variation pattern determination unit is configured to display the determination result by the small hit determination unit. A gaming machine, wherein the first variation pattern group and the second variation pattern group are alternately selected every time the first symbol variation game is started after a small hit.

  (2) In any one of claims 1 to 6, the variation pattern group for the first symbol variation game is provided with a probability variation state in which the probability that a big hit is derived is high. A variation table, a variation pattern distribution table for the first symbol variation game to which a variation time shortening state for shortening the variation time of the first special symbol, the probability variation state, and the variation time shortening state are provided. A gaming machine comprising: a variation pattern distribution table to which variation patterns for the first symbol variation game to which different normal states are assigned are allocated.

  (3) In any one of claims 1 to 6, the game control means includes the first big hit determining means, the first big hit gaming state giving means, the second big hit determining means, and the second big hit determining state. A main control means having a function as a grant means, the small hit determination means, the small hit game state grant means and the variation pattern determination means, and a sub control means electrically connected to the main control means, The sub-control means is connected to an effect changing means operated by a player to execute a notice suggesting that the result of the first symbol variation game or the second symbol variation game may be a big hit. A gaming machine characterized by

  (4) In any one of claims 1 to 6, the small hit determination means may determine that the result of the first symbol variation game is a small hit when the determination result by the first big hit determination means is lost. The game control means determines whether the result of the first symbol variation game is a small hit or a big hit is derived in the first symbol variation game after a predetermined number of round effects have been executed. A game machine comprising: a concealment effect executing means for executing a concealment effect for concealing the probability variation state for a predetermined period when a probability variation state in which the probability of variation varies with a high probability is given. In this way, since the concealment effect is executed to conceal the probability variation state, it is possible to enhance the expectation for the gaming state after the concealment effect.
