Therefore, when operated in the open state ST2, most of the game balls that have passed through the guide passage 21e are received by the ball receiving surface 31a of the second variable member 31.

  In the open state ST2, the second variable member 31 is inclined toward the first big prize opening 30 side. When the second variable member 31 is operated in the open state ST <b> 2, the ball receiving surface 31 a is lowered downward as it approaches the first big prize opening 30. For this reason, the game ball received by the ball receiving surface 31 a of the second variable member 31 is guided to win the first grand prize opening 30. In other words, when the second variable member 31 is operated in the open state ST2, most of the game balls that have passed through the guide passage 21e win the first big prize opening 30.

  The pachinko gaming machine 10 includes a right passage 21h, which is a passage connected to the upper right passage 21f and is narrower than the upper right passage 21f, in the right portion of the gaming area 21. The right passage 21h is below the upper right passage 21f. Here, the flange 41 includes an outer wall 48 that protrudes forward from the flange 41. The outer wall 48 extends substantially parallel to the second partition wall 45 on the right side of the second partition wall 45 extending in the vertical direction. The right passage 21h is a space between the second partition wall 45 and the outer wall 48. The outer wall 48 as the first wall and the second partition wall 45 form a right passage 21h, which is a passage through which game balls circulate. In this embodiment, the right passage 21h is a zigzag passage bent alternately in the left-right direction.

  When it is assumed that the game ball 20 is cut along a plane S2 perpendicular to the surface 20b of the game board 20 and perpendicular to the game ball distribution direction D6 in the right passage 21h, the cross section of the space in which the game ball flows in the right passage 21h is The size is such that two or more game balls are not lined up.

Next, the big hit in the pachinko gaming machine 10 will be described.
The pachinko gaming machine 10 of this embodiment includes a plurality of types of jackpot symbols as special symbol jackpot symbols. The types of jackpot games are determined for each type of jackpot symbol. Note that a plurality of types of jackpot symbols may have a gaming state after the jackpot game ends. In other words, in this embodiment, the jackpot symbol corresponds to a jackpot type that defines a privilege to be given to the player.

  In the big hit game, after the opening effect for notifying the start of the big hit game is performed, a round game in which one of the big winning ports 30 and 32 is opened is performed. A round game is played with a predetermined upper limit number of times as an upper limit. In one round game, one of the big winning openings 30 and 32 is either a first condition for a predetermined upper limit number of game balls to win or a second condition for a predetermined upper limit time to elapse. It is released until the condition is satisfied. In the big hit game, when the final round game is finished, an ending effect for notifying the end of the big hit game is performed. The big hit game is ended with the end of the ending effect.

Next, game play in the pachinko gaming machine 10 of this embodiment will be described.
As shown in FIG. 2, the pachinko gaming machine 10 includes a plurality of routes according to the launch strength of the game balls as routes through which the game balls circulate in the game area 21. In this embodiment, a first path R1 passing through the left side of the center frame 40 to the out port 35 and a second path R2 passing through the right side of the center frame 40 to the out port 35 are formed. . The second route R2 is a route that passes through the upper passage 21c, the bending passage 21d, the guide passage 21e, the upper right passage 21f, and the right passage 21h.

  There is a first start winning opening 27 in the first route R1. The second route R2 includes a first grand prize port 30, a gate 34, a second big prize port 32, and a second start prize port 28. Of the firing strengths of the game balls, the launch strength that is fired so that the game balls circulate through the first route R1 corresponds to the first launch strength, and the game balls are fired so as to circulate through the second route R2. The launch intensity corresponds to the second launch intensity. In this embodiment, launching a game ball with a first firing strength is so-called “left-handed”, and firing a game ball with a second launch strength is so-called “right-handed”. In the big hit game, if the game ball is not hit to the right, the game ball cannot be won in the first big prize opening 30 or the second big prize opening 32.

Next, the operation of the pachinko gaming machine 10 configured as described above will be described.
As shown in FIG. 5, during the big hit game, the game ball hit right by a sufficient launch strength by operating the launch handle 15 passes in the order of the launch passage 21b and the upper passage 21c, along the distribution direction D1. pass. At this time, the attachment portion 41c and the screw 50 do not protrude from the narrowest portion of the upper passage 21c, and the game ball is bounced forward or rolled in an unintended direction by the attachment portion 41c and the screw 50. Without colliding with the first buffer member 46.

  The game ball comes into contact with the first buffer member 46 to reduce the ball power, jumps in the flow direction D <b> 2 toward the second buffer member 47, and further contacts the second buffer member 47. The game ball that has come into contact with the second buffer member 47 slides down along the flow direction D3, which is the downward direction. The game ball flows into the guide passage 21e and is guided along the guide direction D4 toward the upper right passage 21f by the guide passage 21e.

  As shown by the two-dot chain line in the figure, when the second variable member 31 is moved to the open state ST2, the second variable member 31 is positioned on the extension line of the guide direction D4 and the guide direction D4. It extends along the extending direction D5 orthogonal to. Almost all of the game balls that have flowed into the upper right passage 21 f are received by the ball receiving surface 31 a of the second variable member 31 and guided to win the first big prize opening 30.

  In addition, during a normal game, the game ball left-handed at the first launch intensity by operating the launch handle 15 passes through the launch passage 21b and passes through the left side of the center frame 40 to the out port 35. Circulate. The player follows the whereabouts of the game balls so that the game balls flowing through the first route R1 are directed to the warp path 43 and the first start winning opening 27. For this reason, from the viewpoint of improving the interest of the player, it is preferable to change the behavior of the game ball by an obstruction member such as a nail existing in the first route R1. When the mounting portion 41c is disposed so as to protrude toward the game area 21 side (outside) with respect to the second partition wall 45 facing the first path R1, the mounting portion 41c and the screw 50 are in the behavior of the game ball. This is preferable because it gives a change.

According to the above embodiment, the following effects can be obtained.
(1) In the upper passage 21 c through which game balls circulate, the game balls circulate outside the second partition wall 45. For this reason, it can suppress that the specific attachment part 411c which exists in the inner side (near inner surface 45a) rather than the 2nd division wall 45 which defines the upper channel | path 21c gives the influence which does not intend to the game ball to distribute | circulate. For example, if the mounting portion 41c protrudes into the upper passage 21c outside the second partition wall 45, an unintended behavior in which a game ball passing through the upper passage 21c comes into contact with the mounting portion 41c and is bounced forward. There is a possibility of making it a game ball. However, by disposing the specific mounting portion 411c on the inner side of the second partition wall 45, it is possible to prevent the game ball from being flipped forward, and the center frame 40 can be mounted to the game board 20 in a preferable mode.

  (2) At least part of the upper passage 21c is a narrow passage through which only one game ball can pass. The specific attachment portion 411c is inside the upper right portion that defines the narrowest portion of the upper passage 21c in the second partition wall 45, and does not protrude into the upper passage 21c. For this reason, the momentum of the game ball that circulates in the upper passage 21c is prevented from being weakened by the specific mounting portion 411c or rolling in a direction different from the distribution direction D1, and the game sphere that circulates in the upper passage 21c. An unintended influence can be suppressed.

  (3) At least a part of the upper passage 21c is a narrow passage through which game balls can pass only one by one. The upper passage 21 c is a passage that is narrowed so that the game balls that have circulated vigorously are directed toward the first buffer member 46. If the specific mounting portion 411c protrudes into the upper passage 21c as described above, the momentum of the game ball is weakened, and the game ball has an unintended influence that it is difficult to collide with the first buffer member 46. However, the specific attachment portion 411c is inside the portion of the second partition wall 45 that defines the narrowest portion of the upper passage 21c, and does not protrude into the upper passage 21c. For this reason, it can suppress that the momentum of the game ball which distribute | circulates the upper channel | path 21c weakens, and it can suppress giving the unintended influence of becoming difficult to collide with the 1st buffer member 46.

  (4) The specific mounting portion 411c is located inside the second partition wall 45 that defines the upper passage 21c upstream of the guide passage 21e in the game ball distribution direction. The specific mounting portion 411c prevents the game ball flowing through the upper passage 21c from being bounced forward, and allows the game ball to collide with the first buffer member 46 without making the movement of the game ball uneven. In order to make it easy for the game ball to win the first grand prize opening 30, it is desirable to converge the trajectory of the game ball and make the intensity of the movement uniform. For this reason, it is necessary to narrow a part of the upper passage 21c. The specific attachment portion 411c is disposed inside a portion that defines the upper passage 21c in the second partition wall 45. Therefore, it is possible to make the game ball collide with the first buffer member 46 and make it flow into the guide passage 21e stably without making the movement of the game ball non-uniform. In addition, the second variable member 31 is positioned on the guide direction D4 (distribution direction) of the game ball guided by the guide passage 21e in the state where the first big winning opening 30 is opened, and by the guide passage 21e. It extends along the extending direction D5 that intersects the flow direction of the guided game ball. For this reason, the game ball guided by the guide passage 21 e is efficiently taken into the first grand prize opening 30 by the second variable member 31. Therefore, it is possible to reduce the loss of the game balls that circulate in the guide passage 21e at the first big prize opening 30 and improve the interest of the player.

  (5) In the front-rear direction orthogonal to the surface 20 b of the game board 20, the specific attachment portion 411 c is located closer to the game board 20 than the decoration board 47 a included in the center frame 40 and overlaps the decoration board 47 a. Since the specific attachment portion 411c overlaps the back side closer to the game board 20 than the decorative board 47a, it becomes difficult for the player to visually recognize the specific attachment portion 411c and the screw 50, and a decrease in the interest of the player can be suppressed.

  (6) The specific mounting portion 411c is closer to the game board 20 than the decorative board 47a and is positioned so as to overlap the decorative board 47a, but the decorative board 47a includes a through hole 47b. For this reason, the screw 50 can be easily screwed into the mounting hole 41d of the specific mounting portion 411c by the through hole 47b.

In addition, you may change the said embodiment as follows.
The center frame 40 may be configured in an annular shape by combining a plurality of members. For example, the center frame 40 is a portion that is an upper right portion of the second partition wall 45, and may include a frame constituent member that forms a portion that overlaps the decorative plate 47a in the front-rear direction. In this case, the center frame 40 is configured by integrating a frame constituent member and a frame main body that is another part of the center frame 40. The frame component member is fixed and integrated with a screw or the like at a portion adjacent to the frame component member in the frame main body. Each of the frame constituent member and the frame main body includes a wall forming portion that forms a second partition wall 45, and the frame forming member and the wall forming portion erected from the frame main body are connected to form a series of second partition walls 45. It is formed. And the specific attachment part 411c is arrange | positioned along the wall formation part of a frame structural member, and the specific attachment part is located in the opening part 40a side (effect display device 26 side) in the center frame 40 rather than the wall formation part of a frame structural member. 411c is disposed, and the specific mounting portion 411c is disposed inside the second partition wall 45.

  In the case of such a configuration, for example, in order to attach the frame constituent member to the game board 20 with one screw 50, when the screw 50 is inserted into the specific attachment portion 411c, the frame constituent member is There is a risk of turning about 50. When the frame component member rotates, the rotation undesirably affects the distribution of the game balls, particularly the distribution of the game balls in the narrowest portion of the upper passage 21c. Further, the frame component member is disposed at a place where the game ball that collides with the first shock-absorbing member 46 and hits it back is not preferable to rotate.

  Therefore, it is preferable to attach the frame constituent member in a state in which the rotation is restricted. However, in order to provide the attachment portion 41 c other than the specific attachment portion 411 c, it is not preferable because the attachment portion 41 c is disposed in the upper passage 21 c outside the second partition wall 45. Therefore, in order to prevent the specific mounting portion 411c from unintentionally affecting the distribution of the game ball while restricting the rotation of the frame component member, the frame component member is fixed to the frame body with a screw or the like. . That is, the frame component member is not attached to the game board 20 with only one screw 50 inserted through the specific attachment portion 411c, but is attached to the game board 20 while being fixed to the frame body with other screws. It is attached.

-There is no decoration board 47a in the front side of the specific attachment part 411c, and the specific attachment part 411c does not need to be covered with the decoration board 47a.
The specific attachment portion 411c may be in a portion other than the inside of the upper right portion of the second partition wall 45.

  For example, when the center frame 40 includes a spherical passage that crosses the opening 40a of the center frame 40, the mounting portion 41c does not protrude into the spherical passage, and the second partition wall that forms the spherical passage You may arrange | position inside.

-Of the plurality of mounting portions 41 c, all of the mounting portions 41 c disposed along the second partition wall 45 may be disposed inside the second partition wall 45.
The direction in which the guide passage 21e extends can be changed as appropriate. That is, the guide direction D4 of the game ball by the guide passage 21e can be changed as appropriate. The second variable member 31 is disposed at any position as long as the second variable member 31 is located on the extension line of the guide direction D4 and extends along the extending direction D5 intersecting the guide direction D4 in the open state ST2. May be.

  The positions of the guide passage 21e, the first big prize opening 30, and the second variable member 31 may be changed. For example, some or all of the guide passage 21 e, the first big prize opening 30, and the second variable member 31 may be located below the center of the game area 21.

The bending passage 21d may not be provided, and the guide passage 21e may be connected to the upper passage 21c.
-The 1st big winning opening 30 may be arrange | positioned on the extension line | wire of the guidance direction D4 of the game ball by the guidance channel | path 21e.

  The specific passage having a size that does not line up with two or more game balls may be the guide passage 21e or the right passage 21h. When the guide passage 21 e is a specific passage, the first wall is a protruding wall 41 b included in the center frame 40 and is present in the game area 21. Further, the second wall becomes the second partition wall 45, and the attachment portion 41 c is disposed inside the second partition wall 45. When the right passage 21h is a specific passage, the first wall is the outer wall 48 included in the center frame 40 and is present in the gaming area 21. Further, the second wall becomes the second partition wall 45, and the attachment portion 41 c is disposed inside the second partition wall 45.

  -In the 2nd division wall 45, you may arrange | position the attaching part 41c inside the site | part which defines the channel | path of the magnitude | size in which two or more game balls are located in a line. In this case, a passage having a size in which two or more game balls are arranged is the upper right passage 21f or the bent passage 21d.

  If the frame member has an opening, the opening is attached so as to overlap with the opening 20a of the game board 20, and the passage through which the game balls circulate is formed by the first rail 22, A member other than the frame 40 may be used.

When the first wall is the second rail 23 and a path for a game ball is formed by the second rail 23 and the second partition wall 45, the mounting portion 41c may be disposed inside the second partition wall 45. Good.
The second wall may be a wall other than the second partition wall 45 as long as it is a wall existing in the center frame 40.
