Description

  The present invention relates to a pachinko machine.

  Conventionally, there is known a pachinko machine equipped with a probability variation function that varies the winning probability (big hit probability) in a special symbol lottery.

  In this type of pachinko machine, it is common to shift from a low probability state (normal state) with a relatively low probability of jackpot to a high probability state (probability variation state) with a relatively high probability via a jackpot game. is there. In addition, as a method for determining which of the low-probability state and the high-probability state to shift to after a big hit game, there are two known methods: an internal lottery method and a physical lottery method.

  As the latter based on the physical lottery, a so-called V-attacker having a specific area (also referred to as a V zone) is known as a big winning opening that is opened during the big hit game. If a game ball that has entered the V-attacker passes a specific area while the V-attacker is released, the probability of winning in the special symbol lottery is higher than the normal game state after the jackpot game is over (probability variation state) Will surely occur.

  Two types of jackpot games are prepared: a long-open jackpot game and a short-open jackpot game. In a long-open big hit game, the V attacker's release time is set to a long time, and the game ball enters the V attacker, and the game ball passes through the specific area with a probability of almost 100%. On the other hand, in the short hit big hit game, the V attacker's release time is set to a short time, and it is difficult to enter the game ball into the V attacker, and the probability that the game ball passes through the specific area is extremely low.

JP 2013-103091 A

  However, in a short-open big hit game, there is a possibility that the game ball is hit (targeted) so that the game ball enters the open V attacker in accordance with the timing when the V attacker is released. If this aim is successful with a high probability, the probability of occurrence of a probabilistic state will increase more than expected, and there is a risk of losing the hall in which the pachinko machine is installed.

  An object of the present invention is to provide a pachinko machine that can prevent the aiming of a game ball in accordance with the timing at which a special winning opening is opened.

  The present invention will be described below. In order to facilitate understanding of the invention, reference numerals and the like in the accompanying drawings are appended in parentheses, but the present invention is not limited to the display form.

  In order to achieve the above object, a pachinko machine (1) according to the present invention is provided on a game board (11), and is opened during a jackpot game, and a grand prize port (111) , 251) are provided in the opening / closing plates (112, 253, 254) and the big winning opening (111, 251), and the passing of the game ball in the big hit game causes a probability variation state after the big hit game A specific area (113) as a condition, a slope (47, 202) provided in the game board (11), inclined downward toward the big prize opening (111, 251) and allowing a game ball to roll, As a route on the board (11) above the slopes (47, 202), through which the game balls selectively pass, the game balls are directed toward the grand prize opening (111, 251) without going through the slopes. Drop from above A ball diversion mechanism (45, 201, 261, 262, 263) having a separate route and a normal route for dropping the game ball on a slope (47, 202) upstream of the special winning opening through a route different from the special route. ).

  According to this configuration, when the big winning opening (111, 251) is opened during the big winning game and the game ball entering the big winning opening (111, 251) passes the specific area (113), the big winning game After completion of the probability variation state is generated.

  The game board (11) is provided with slopes (47, 202) that incline downward toward the grand prize opening (111, 251). A spherical branch mechanism (45, 201, 261, 262, 263) having a special route and a normal route is provided at a position above the slope (47, 202). The game ball passing through the special route falls from above toward the grand prize opening (111, 251), and the game ball passing through the normal route is on the slope (47, 202) upstream from the big prize opening. Fall. Therefore, the time from when the game ball is launched until the game ball reaches the big winning opening (111, 251) varies depending on whether the game ball passes the special route or the normal route.

  As a result, when the grand prize opening (111, 251) is opened for a short time, the player adjusts the timing of the game ball firing, and the game ball is won during the opening of the big prize opening (111, 251). It becomes difficult to reach the mouth (111, 251) in a timely manner. That is, when the special winning opening (111, 251) is opened for a short time, it is difficult to successfully aim the game ball in accordance with the opening timing of the special winning opening (111, 251). Therefore, it is possible to prevent the aiming of the game ball in accordance with the timing when the special winning opening (111, 251) is opened.

  The pachinko machine (1) is provided on the game board (11) and has an out port (14, 255) and a slope (47, 202) for collecting non-winning game balls from the game board (11) into the machine. And a distribution mechanism (44) that distributes game balls to either the slope (47, 202), the ball diversion mechanism (45), or the out port (14, 253, 254). It may be a thing.

  The game balls are distributed to either the slope (47, 202), the ball diversion mechanism (45, 201, 261, 262, 263) or the out-port (14, 253, 254), so ) Or the success probability of aiming at a game ball in accordance with the release timing can be reduced. Therefore, it is possible to further prevent aiming of the game ball in accordance with the timing when the special winning opening (111, 251) is opened.

  The ball diversion mechanism (45, 201) includes a plurality of stages (62, 63, 64) provided in a stepped shape, and at least one stage (62, 63) temporarily holds a game ball. You may be comprised so that it can be made to stay.

  Due to the temporary stay of the game ball on at least one stage (62, 63, 212), the time from the launch of the game ball until the game ball reaches the grand prize opening (111, 251) is irregular. Change. Therefore, it is possible to reduce the probability of successful hitting of the game ball in accordance with the timing when the special winning opening (111, 251) is opened. Therefore, it is possible to further prevent the aiming of the game ball in accordance with the timing when the special winning opening (111, 251) is opened.

  The lowermost stage (64, 213) may be formed in a shape that distributes the game balls to either a special route or a plurality of normal routes to flow down.

  In addition, the pachinko machine (1) controls the open / close plates (112, 253, 254), and opens and closes the big winning opening (111, 251) according to the difficulty level of the game ball passing through the specific area (113). It may further include an opening / closing control means (131) to be operated.

  According to the present invention, since the time from the launch of a game ball until the game ball reaches the grand prize opening changes, the player can set the timing for launching the game ball when the big prize opening is opened for a short time. As a result, it becomes difficult for the game ball to reach the big prize opening in a timely manner while the big prize opening is open. Therefore, it is possible to prevent the aiming of the game ball in accordance with the timing when the special winning opening is opened.

  When the game ball passes through the gate 43 during the symbol change in the normal symbol display unit 121, the normal symbol lottery process (hit determination and notification of the result) is suspended up to four passes. The number of holdings of the normal symbol lottery process is displayed by the number of lamps on the normal symbol holding display unit 122. The held regular symbol lottery process is digested in order from the oldest hold.

  The game balls that have passed through the gate 43 hit the blades 54 of the windmill 44, rotate the windmill 44 (rotating member 52), and are distributed to the left and right by the rotation.

  The game balls distributed to the left side by the windmill 44 land on the upper surface 71 of the ball feed stage 61 of the ball diversion mechanism 45, and roll to the back while colliding with the protrusions 74 on the upper surface 71 due to the inclination of the upper surface 71. To do. Depending on the momentum and direction of the game ball when dropped, the game ball may reach the left front end of the upper surface 71. The game ball once climbs the inclined surface of the return portion 72, then descends the inclined surface, and rolls on the upper surface 71 to the back side. The game ball that has reached the left rear end portion of the upper surface 71 by rolling to the back side further rolls on the extension portion 73 and falls from the rear end edge of the extension portion 73 to the back side, and the upper stage. Land on the upper surface 76 of 62. The other game balls fall from the rear edge of the upper surface 71 to the far side, and land on the upper surface 76 of the upper stage 62 without colliding with or colliding with the guide surface 75 (see FIG. 5).

  Since the upper surface 76 of the upper stage 62 is curved, the game ball repeatedly reciprocates left and right on the upper surface 76, and then passes through the notch 82 of the first wall portion 81 from the center in the left and right direction of the upper surface 76. Fall to the front side. The game ball falling from above the extension portion 73 of the ball feed stage 61 lands at a higher position on the upper surface 76 of the upper stage 62 than the game ball falling from a portion other than the extension portion 73. A large reciprocating motion from side to side. The magnitude of the reciprocation on the upper surface 76 also varies depending on the landing position of the upper stage 62 on the upper surface 76 of the game ball falling from a portion other than the extending portion 73 of the ball feeding stage 61. Therefore, the staying time of the game ball in the upper stage 62 is irregular.

  The game ball falling from the upper stage 62 hits the boundary between the arc surfaces 77 and 78 of the middle stage 63 and then lands on one of the arc surfaces 77 and 78. Since the arc surfaces 77 and 78 are curved, the game balls that have landed on the arc surfaces 77 and 78 repeatedly reciprocate left and right on the arc surfaces 77 and 78, respectively. After reciprocating, the game ball on the left arc surface 77 falls from the center in the left-right direction of the arc surface 77 through the left notch 86 of the second wall 85 to the near side. After reciprocating, the game ball on the right arc surface 78 falls from the center in the left-right direction of the arc surface 78 through the right notch 87 of the second wall portion 85 to the near side.

  A game ball falling from the left arc surface 77 of the middle stage 63 hits a boundary portion between the arc surface 83 and the continuous arc surface 84 of the lower stage 64, and then on one of the arc surface 83 or the continuous arc surface 84. Land. The game ball that has landed on the arc surface 83 falls from the arc surface 83 through the ball discharge port 91 at the left end of the ball discharge plate 88. Further, the game ball falling from the right arc surface 78 of the middle stage 63 lands on the continuous arc surface 84 of the lower stage 64. The game ball that has landed on the continuous arc surface 84 falls from any one of the ball discharge ports 92, 93, 94 of the ball discharge plate 88 from the continuous arc surface 84.

  The ball discharge port 91 at the left end of the ball discharge plate 88 is disposed immediately above the second grand prize winning port 111. Therefore, a game ball falling from the ball discharge port 91 enters the second large winning port 111 if the second large winning port 111 is open, and the second large winning port 111 is closed by the opening / closing plate 112. In this case, the robot lands on the opening / closing plate 112 and moves from the opening / closing plate 112 to the upper surface 105 of the second slope 48.

  That is, the route through which the game ball passes through the ball discharge port 91 is a special route for dropping the game ball onto the second grand prize winning port 111 (opening / closing plate 112). While the second big prize opening 111 is opened, the game ball passing through the special route does not roll on the upper surface 104 of the first slope 47 and enters the second big prize opening 111 straight. Therefore, the player can visually entertain the player.

  Further, the game ball that falls from any of the ball discharge ports 92, 93, 94 of the ball discharge plate 88 lands on the upper surface 104 of the first slope 47, rolls on the upper surface 104, and moves to the left end of the upper surface 104. To the second big prize opening 111. That is, the route through which the game ball passes through any of the ball discharge ports 92, 93, 94 is a normal route for dropping the game ball onto the upper surface 104 of the first slope 47. The game ball enters the second big prize opening 111 if the second big prize opening 111 is open, and on the opening / closing board 112 if the second big prize opening 111 is closed by the opening / closing plate 112. Land and move from the opening / closing plate 112 to the upper surface 105 of the second slope 48.

  The game ball that has moved onto the upper surface 105 of the second slope 48 rolls on the upper surface 105 and falls from the left edge of the upper surface 105 to the lower left.

  On the other hand, the game balls distributed to the right side by the windmill 44 enter the bypass channel 46 and pass through the bypass channel 46. The game ball that has passed through the detour channel 46 rebounds on the upper surface 103 of the triangular block 102 and either lands on the upper surface 104 of the first slope 47 or depends on the direction of the rebound and the momentum of the game ball. 49 and passes through the out-sphere channel 49. The game balls that have passed through the out ball channel 49 are collected from the out port 116 into the machine.

  In the operation pattern E, as shown in FIG. 9, after the closed state of the second big prize opening 111 was maintained for 2000 msec from the start of the round, the second big prize opening 111 was opened, and the open state was maintained for 60 msec. After the second grand prize opening 111 is closed and the closed state is maintained for 500 msec, the second big prize opening 111 is opened, and after the open state is maintained for 60 msec, the second big prize opening 111 is closed, After the closed state is maintained for 500 msec, the second big prize opening 111 is opened, and after the open state is maintained for 60 msec, the second big prize opening 111 is closed, and after the closed state is maintained for 500 msec, After the winning opening 111 is opened and the open state is maintained for 60 msec, the second large winning opening 111 is closed and the closed state is maintained for 4000 msec. After the mouth 111 is opened and the open state is maintained for 60 msec, the second big prize opening 111 is closed, and after the closed state is maintained for 500 msec, the second big prize opening 111 is opened and the open state is maintained for 60 msec. After the second big prize opening 111 is closed and the closed state is maintained for 500 msec, the second big prize opening 111 is opened, and after the open state is maintained for 60 msec, the second big prize opening 111 is closed. After the closed state is maintained for 500 msec, the second grand prize opening 111 is opened, and after the open state is maintained for 60 msec, the second big prize opening 111 is closed and the closed state is maintained for 4000 msec, After the grand prize opening 111 is opened and the open state is maintained for 14520 msec, the second big prize opening 111 is closed and the closed state is maintained for 1800 msec. It is a pattern of the opening and closing operation.

  In the sixth round, the second big prize opening 111 performs the opening / closing operation with the operation pattern B, and the specific area 113 performs the opening / closing operation with the operation pattern H, so that the second big prize opening 111 only in 60 msec after the start of the round. And the specific area 113 is simultaneously opened. After the opening of the specific area 113 for 60 msec, while the closed state of the specific area 113 is maintained, a period in which the closed state of the second big prize opening 111 opened and closed in the operation pattern B is maintained for 1800 msec has elapsed. The round ends.

  Therefore, in the jackpot game in which “16R first special figure 6” is displayed on the first special symbol display section 32, the game ball that has entered the second big prize opening 111 in the sixth round almost passes the specific area 113. The probability that at least one game ball passes through the specific area during the round is almost 0%.

  Further, in the eighth round, the second grand prize opening 111 performs the opening / closing operation with the operation pattern E, and the specific region 113 performs the opening / closing operation with the operation pattern H, so that the open state of the specific region 113 is maintained up to 28000 msec. In the meantime, after the second large winning opening 111 is repeatedly opened for 60 msec, the second large winning opening 111 is opened for 14520 msec for a long time.

  Therefore, in the jackpot game when “16R first special figure 6” is displayed on the first special symbol display unit 32, “16R first special figure 4” is displayed on the first special symbol display unit 32. There is a higher possibility that a game ball will enter the second grand prize opening 111 in the eighth round than a big hit game, and there is a high possibility that the game ball will pass through the specific area 113.

  Thereafter, when the jackpot game ends (YES in step S3), the CPU 141 determines whether or not at least one game ball has passed through the specific area 113 during the jackpot game (step S4).

  If the game ball has passed through the specific area 113 (YES in step S4), the CPU 141 turns on a probability change flag provided in the RAM 143 (step S5).

  When the probability variation flag is turned on, after the jackpot game is over, the gaming state shifts to a probability variation state (probability variation state) and a short time state. The probability variation state is a state in which there is a higher probability that the result of the first special drawing lottery and the second special drawing lottery will be a big hit compared to the normal state. Compared to the normal state, the time-short state has a higher probability that the result of the normal symbol lottery will be a hit, and the one-time expansion time of the movable blade 34 is longer. Therefore, in the short time state, it is possible to easily obtain a prize for the second start port 33 as compared with the normal state. The probability change state continues until the total number of times of the first special figure lottery and the second special figure lottery reaches a predetermined probability change number (for example, 160 times), and the time reduction state ends together with the probability change state.

  When the probability variation state ends, the probability variation flag is reset to off.

  On the other hand, when the game ball does not pass the specific area 113 during the jackpot game (NO in step S4), the CPU 141 does not turn on the probability variation flag but keeps the probability variation flag off (step S6).

  When the probability variation flag is kept off, after the jackpot game is over, the gaming state shifts to the short-time state. The time reduction state continues until the total number of times of the first special figure lottery and the second special figure lottery reaches a predetermined number of time reductions (for example, 100 times).

<Effect>

  As described above, when the second big prize opening 111 is opened during the big hit game, and the game ball entering the second big prize opening 111 passes through the specific area 113, the probable state is changed after the big hit game ends. Is born.

  The game board 11 is provided with a ball passing unit 41, and the ball passing unit 41 is provided with a first slope 47 that is inclined downward toward the second grand prize winning opening 111. A spherical branch mechanism 45 having a special route and a normal route is provided at a position above the first slope 47. The game balls that pass through the special route fall from the ball discharge port 91 of the ball discharge plate 88 onto the second grand prize winning port 111, and the game balls that pass through the normal route pass through the ball discharge ports 92 and 93 of the ball discharge plate 88. , 94 fall on the upper surface 104 of the first slope 47. For this reason, the time from when the game ball is launched until the game ball reaches the second grand prize opening 111 varies depending on whether the game ball passes the special route or the normal route.

  As a result, when the second grand prize opening 111 is opened for a short time, the player adjusts the launch timing of the game ball, and the second big prize opening 111 is opened while the second big prize opening 111 is opened. It is difficult to reach the target in a timely manner. That is, when the second big prize opening 111 is opened for a short time, it is difficult to successfully aim the game ball at the timing when the second big prize opening 111 is opened. Therefore, it is possible to prevent the aiming of the game ball in accordance with the timing at which the second big winning opening 111 is opened.

  Further, the ball passing unit 41 is provided with a windmill 44, and the game balls are distributed by the windmill 44 to either the ball diversion mechanism 45, the upper surface 104 of the first slope 47, or the out port 14.

  As a result, it is possible to reduce the success probability of aiming at the game ball in accordance with the timing at which the second grand prize opening 111 is opened. Therefore, it is possible to further prevent aiming of the game ball in accordance with the timing at which the second grand prize winning opening 111 is opened.

  The spherical branching mechanism 45 includes an upper stage 62, an intermediate stage 63, and a lower stage 64 that are provided in a stepped shape. The upper stage 62 and the middle stage 63 are configured to allow the game ball to stay temporarily on the upper surface 76 and the arc surfaces 77 and 78, respectively.

  Due to the temporary stay of the game ball, the time from the launch of the game ball to the arrival of the game ball at the second grand prize opening 111 changes irregularly. Therefore, it is possible to reduce the success probability of aiming the game ball in accordance with the timing at which the second grand prize winning opening 111 is opened. Therefore, it is possible to further prevent the aiming of the game ball in accordance with the timing at which the second big winning opening 111 is opened.

Each notch 236, 237 is notched downward from the upper edge of the ball stop 235 and has a width equal to or greater than the diameter of the game ball in the left-right direction. The lower end edges of the notches 236 and 237 are located at the same height as the upper surface 233 of the lower stage 213. The right notch 236 is located at the right end of the lower stage 213. The left notch 237 is located at the approximate center in the left-right direction of the lower stage.

  A ball discharge plate 238 is provided below the lower stage 213. The ball discharge plate 238 has a plate shape extending in the vertical direction and the horizontal direction. A spherical outlet 239 is formed in the spherical discharge plate 238. The ball outlet 239 is located below the portion of the ball stop 235 that is sandwiched between the two notches 236 and 237, and is formed to a size that allows one game ball to pass through.

  The sphere inflow port 232 and the sphere outflow port 239 form an entrance and an exit of a special route, respectively. The special route is formed on the back side of the ball discharge plate 238. The game ball that has entered the ball inflow port 232 passes through the special route and falls from the ball outflow port 239.

  The first slope 202 is disposed below the ball discharge plate 238 of the ball diversion mechanism 201. The upper surface 241 of the first slope 202 has a width equal to or larger than the diameter of the game ball in the front-rear direction, and is formed in a substantially flat surface extending in a slanting direction to the left.

  The second slope 203 is disposed on the left side with respect to the first slope 202. The right edge of the upper surface 242 of the second slope 203 is connected to the left edge of the upper surface 241 of the first slope 202.

The right edge of the upper surface 243 of the third slope 204 is connected to the left edge of the upper surface 242 of the second slope 203. The upper surface 243 of the third slope 204 has a width that is equal to or larger than the diameter of the game ball in the front-rear direction, and is formed on a flat surface that is inclined more slowly to the left than the upper surface 242 of the second slope 203.

  In the first slope 202, a second grand prize opening 251 is formed. The second big prize winning opening 251 is formed as an opening that is divided into two parts by a plate-like separation part 252 and opened up and down. The left portion of the second grand prize winning opening 251 is located below the left notch 236 of the ball stopper 235. The right portion of the second grand prize winning opening 251 is located on the left side of the ball outlet 239.

  Opening and closing plates 253 and 254 are provided above the left and right portions of the second big prize opening 251, respectively. The open / close plates 253 and 254 are configured to be movable between an advanced position where the open / close plate 253 is advanced onto the second big prize opening 251 and a retracted position where the open / close plates are retracted to the back side from the closed position. The opening / closing plates 253 and 254 respectively close the second big prize opening 251 at the advance position, and open the second big prize opening 251 at the retracted position. A single solenoid (not shown) is connected to the open / close plates 253 and 254 as a drive source, and the open / close plates 253 and 254 are simultaneously displaced between the advanced position and the retracted position by the solenoid. Thereby, the left side part and the right side part of the 2nd big winning opening 251 are opened and closed simultaneously. The second big winning opening 251 is opened only during the big hit game.

  In the second grand prize opening 251, a specific area 113 and a non-specific area 114 are formed in this order in the passing direction of the game balls on the flow path of the game balls entering the second big prize opening 251. A V shutter 115 is provided above the specific area 113. The V-shutter 115 is configured to be movable between an advanced position that has advanced on the specific area 113 and a retracted position that has been retracted from the closed position to the back side. The V shutter 115 closes the specific area 113 at the advanced position and opens the specific area 113 at the retracted position. When the specific area 113 is open, the game ball passes through the specific area 113 with a high probability, and when the specific area 113 is closed, the game ball passes through the non-specific area 114.

  The out sphere channel 49 is formed on the right side of the first slope 202. The upper end of the out ball channel 49 is located below the notch 237 and is opened upward as an entrance of the game ball to the out ball channel 49. An out port 255 is formed at the lower end of the out ball channel 49.

<Flow of game balls in the ball passage unit>

  The game ball that has been hit to the right enters the ball introduction path 42 from the entrance 50 of the ball introduction path 42 and passes through the ball introduction path 42. The game ball discharged from the ball introduction path 42 passes through the gate 43.

  The game balls that have passed through the gate 43 hit the blades 54 of the windmill 44, rotate the windmill 44 (rotating member 52), and are distributed to the left and right by the rotation.

  The game balls distributed to the left side by the windmill 44 land on the upper surface 221 of the ball feed stage 211 of the ball diversion mechanism 45, and roll to the back while colliding with the protrusions 224 on the upper surface 221 due to the inclination of the upper surface 221. To do. The game ball that has reached the opening 223 of the upper surface 221 by rolling to the back side falls from the opening 223 and lands on the left end of the arc surface 225 on the left side of the upper stage 212 through the ball feeding route.

  Since the arc surfaces 225 and 226 of the upper stage 212 are curved, the game ball that has landed on the arc surface 225 repeatedly reciprocates left and right on the arc surfaces 225 and 226. Thereafter, most of the game balls fall from the arc surface 225 or the arc surface 226 to the near side.

  A game ball that falls from the upper stage 212 to the near side lands on the upper surface 233 of the lower stage 213. Since the upper surface 233 is curved, the game ball that has landed on the upper surface 233 repeatedly reciprocates left and right on the upper surface 233. Then, after the reciprocating motion, the game ball passes through one of the two notches 236 and 237 and falls to the near side.

  The left notch 236 is located above the separation part 252 of the first slope 202, and the game ball falling through the notch 236 lands on the separation part 252. That is, the route through which the game ball passes through the notch 236 is a normal route for dropping the game ball onto the first slope 202. The game ball rolls on the upper surface 241 of the first slope 202 toward the left side portion of the second grand prize winning opening 251 or rebounds on the upper surface 241. The game ball enters the second big prize opening 251 if the second big prize opening 251 is opened, and the game ball moves on the opening / closing board 253 if the second big prize opening 251 is closed by the opening / closing plate 253. It passes through the upper surface 242 of the second slope 203 from the opening / closing plate 253 and moves onto the third slope 204.

  The game ball that has moved onto the upper surface 243 of the third slope 204 rolls on the upper surface 243 and falls to the lower left from the left edge of the upper surface 243.

  In addition, the game ball falling through the notch 237 enters the out-ball channel 49 and passes through the out-ball channel 49. The game balls that have passed through the out ball channel 49 are collected from the out port 255 into the machine.

  A game ball that reciprocates left and right on the arc surfaces 225 and 226 of the upper stage 212 flows into the ball inlet 232 depending on the momentum. The game ball that has flowed into the ball inflow port 232 passes through the special route, then falls from the ball outflow port 239, and lands on a portion of the upper surface 241 of the first slope 202 that is located on the right side of the second big winning opening 251. . That is, the special route is a special route for dropping the game ball onto the upper surface 241 of the first slope 202 aiming at the right side portion of the second grand prize winning opening 251. Then, the game ball passes through the right side portion and the left side portion of the second big prize winning opening 251 in order while rolling the upper surface 241 of the first slope 202 toward the second slope 203 side. Therefore, when the game ball passes through the second grand prize opening 251, if the second grand prize opening 251 is opened, the game ball enters the right portion of the second big prize opening 251 and the second big prize opening 251 opens and closes. If it is closed by the plate 254, it passes over the opening / closing plate 254 and reaches the left portion of the second big prize winning opening 251. At this time, if the second big prize opening 251 is open, the left side portion of the second big prize opening 251 is entered. Therefore, a game ball that has passed the normal route has almost no possibility of entering the right side portion of the second grand prize opening 251 (there is only one possibility of entering the second big prize opening 251), whereas a special route ( The game balls that have passed through the special route may enter the right and left portions of the second big prize opening 251 while rolling on the upper surface 241 of the first slope 202 (into the second big prize opening 251). There is a possibility of entering twice). Therefore, by providing the special route, it is possible to increase the player's expectation for entering the second big prize opening 251 and to make the player enjoy the jackpot game. A game ball that does not enter the second grand prize opening 251 moves from the opening / closing plate 253 to the third slope 204 through the upper surface 242 of the second slope 203.

  The game ball that has moved onto the upper surface 243 of the third slope 204 rolls on the upper surface 243 and falls to the lower left from the left edge of the upper surface 243.

The exit 297 of the special route 292 is disposed above the second big prize winning opening 111.

  The game ball that has passed through the gate 43 rolls toward the sword tip 294 along the upper surface 295 of the blade portion of the sword-shaped rail 291, and reaches the sword tip 294 without dropping from the upper surface 295, or on the way Then, it falls from the upper surface 295 and rolls toward the upper surface 104 of the first slope 47. The game ball that has reached the sword tip 294 enters the entrance 296 of the special route 292, passes through the special route 292, and falls from the exit 297 onto the second grand prize winning port 111.

  The upper surface of the opening / closing plate 112 is not limited to the planar shape shown in FIG. 3, but may be formed in the shape shown in FIGS.

  In the shape shown in FIG. 16, an inclined surface portion 303 is formed at the back end portion of the upper surface 302. The inclined surface portion 303 has a planar shape inclined so as to be higher toward the back side. The left end edge of the inclined surface portion 303 is longer than the right end edge, and the front end edge of the inclined surface portion 303 extends linearly so as to be located on the far side toward the right side.

  In the shape shown in FIG. 17, an inclined surface portion 306 is formed at the right back end portion of the upper surface 305. That is, a substantially triangular prism-shaped projecting portion having an upper surface inclined downward toward the front is formed at the right rear end portion of the upper surface 305, and the upper surface of the projecting portion forms an inclined surface portion 306.

  In the shape shown in FIG. 18, the middle part 309 in the front-rear direction of the upper surface 308 is inclined downward while being gently curved. The inclined middle portion 309 forms an inclined surface portion whose shape is steeper on the left side and gentler on the right side.

  When the shapes shown in FIGS. 16 to 18 are adopted, a game ball that passes through the special route, falls from the ball discharge port 91 (see FIG. 3), and lands on the upper surfaces 302, 305, and 308 of the opening and closing plate 112. Rebounds to the near side at the inclined surface portions 303, 306, and 309. Then, the game ball repeatedly jumps between the opening / closing plate 112 and the transparent plate 3 (see FIG. 1), and then moves to the second slope 48 on the left side of the opening / closing plate 112. Therefore, as compared with the case where the game ball flows from the first slope 47 onto the opening / closing plate 112, the game ball can stay on the opening / closing plate 112 longer, and the winning rate to the second big winning opening 111 is higher. can do.

  In the shape shown in FIG. 19, crease-like irregularities are formed on the entire upper surface 311.

  When the shape shown in FIG. 19 is adopted, the game ball is difficult to slide on the upper surface 311 of the opening / closing plate 112. Therefore, the game ball can stay on the opening / closing plate 112 for a long time, and the winning rate to the second big winning opening 111 can be increased.

  Further, as a configuration that allows the game ball to stay on the opening / closing plate 112 for a long time, in addition to the above-described configuration, a configuration in which a rotating plate is provided on the upper left side of the opening / closing plate 112 or above the left end portion may be adopted. The rotating plate is formed in a plate shape extending in the vertical direction and the front-rear direction. The upper end portion of the rotating plate is rotatably supported by a rotating shaft extending in the front-rear direction. A game ball that lands or flows on the opening / closing plate 112 collides with the rotating plate, and its momentum is weakened. Thereafter, the game ball moves on the second slope 48 on the left side of the opening / closing plate 112 by rotating the rotation plate. Therefore, the game ball can stay on the opening / closing plate 112 for a long time.

  Further, in the first embodiment described above, the configuration in which the game ball falls on the second grand prize winning port 111 from the ball discharge port 91 (special route) is taken up, but a bowl-shaped obstacle is provided below the ball discharge port 91. The game ball falling from the ball discharge port 91 may land on the obstacle and bounce off, and the bounced game ball may land on the lower end portion of the upper surface 104 of the first slope 47. .

  In addition, various design changes can be made to the above-described configuration within the scope of the matters described in the claims.
