It becomes an easy winning area K. In the easy-to-win area K, at least one game ball can enter (can be included), and there is no entry path other than passing through the winning line segment N. Since there are no divisional obstacle nails or a ball entry part into which a game ball can enter, there is little change in the flow direction of the game ball in the easy-to-win area K, and the game ball that has flowed into the easy-to-win area K Most of them are designed to easily win the side big winning opening 17.

  Most of the game balls that have not flown into the second start winning opening 14B after flowing down the flow area 22B pass through the winning line segment N without colliding with the support column 36 and enter the easy-to-win area K. It is possible to enter the winning opening 17. A part of the game balls that have flowed down the flow area 22B and did not enter the second start winning opening 14B collide with the support column 36 and are distributed up and down. The game balls distributed to the lower side enter the easy winning area K and can enter the side large winning opening 17, while the game balls distributed to the upper side pass through the arc passage 37 and then enter the easy winning area K. Enter or go downstream. Note that the lower nail N2, the side protruding wall 33H, the support column 36, and the like correspond to the “channel distribution protrusion” of the present invention, and among these “channel distribution protrusions”, the column 36 is the “special”. Corresponds to the “distribution protrusion”. In the present embodiment, the interval between the winning line segment N and the arc portion 24E or the second region constituting wall 24B is configured to be at least one game ball or more.

Are formed integrally with the winning unit 25. Thereby, since arrangement | positioning of the rolling path 35, the side large winning opening 17, and the support | pillar 36 is fixed, the dispersion | variation in the winning line segment N by an assembly | attachment error is suppressed. The winning unit 25 is formed by attaching a unit lid 25A (corresponding to the “front facing plate” of the present invention) to the unit main body 25B (see FIGS. 5 and 6), and the front plate 25M of the unit main body 25B (“ (Corresponding to “hole closing plate”) is directed to the opening edge of the accessory mounting hole (not shown) formed in the game board 11 and the body portion 25N behind the front plate 25M of the unit body 25B is the accessory. The game board 11 is fixed in a state of being received in the mounting hole.

  Further, the unit lid 25A is formed of a transparent resin, and the game balls flowing down the front surface of the unit main body 25B including the game balls rolling on the rolling path 35 are visible from the front. In addition, as shown in FIG. 5, a trapezoidal shape is formed on the front surface of the front plate 25 </ b> M of the unit main body 25 </ b> B, one in the upper part of the front position of the side special winning opening 17 and two in the upper part of the side special winning opening 17. A main body side meandering protrusion 25D protruding forward is formed. As shown in FIG. 6, a lid-side meandering protrusion 25 </ b> E that protrudes rearward in a trapezoidal shape is formed on a part of the back surface of the unit lid 25 </ b> A that faces an intermediate position between the main-body-side meandering protrusions 25 </ b> D. Yes. The main body side meandering protrusion 25D and the lid side meandering protrusion 25E correspond to the “forced meandering protrusion” of the present invention, and meandering the game ball heading toward the side prize winning port 17, the rolling speed of the game ball is suppressed. Therefore, it is possible to increase the certainty of winning in the side big winning opening 17.

  This completes the description of the configuration of the present embodiment. Next, the effect of the pachinko gaming machine 10 of this embodiment will be described. In the pachinko gaming machine 10 according to the present embodiment, when a game ball enters the second start winning opening 14B and wins the special symbol determination, a big hit game in which the side big winning opening 17 is opened is executed. . In this jackpot game, a game ball is driven into the right region 21R in order to enter the side big prize opening 17.

  The game ball that has been driven into the right region 21R passes through the trunk route 22A, is discharged to the flow-down region 22B, and flows downward. The game balls that flow down the flow area 22B and flow down the area away from the support column 36 out of the game balls that have not flown into the second start winning opening 14B exceed the winning line segment N and are easy to win. Enter K, roll on the rolling path 35 and enter the side big prize opening 17. In addition, a part of the game ball flowing down in the vicinity of the support column 36 is guided by the support column 36 toward the arc passage 37, while the rest enters the easy-to-win area K exceeding the winning line segment N, and the rolling path 35. To enter the side big prize opening 17.

  Thus, in the pachinko gaming machine 10 according to the present embodiment, the easy winning area K including the side large winning opening 17 is formed, and one or more game balls can enter the easy winning area K. Since there is no entry path other than passing through the winning line segment N in size, and there is no entrance part where a game ball can enter other than the side large winning opening 17 in the easy winning area K, the side large When the winning opening 17 is open, a game ball that has passed through the winning line segment N and entered the easy winning area K rolls on the rolling path 35 and wins the side large winning opening 17 or the side large The winning opening 17 will be won directly. That is, the winning line segment N, which is the boundary line of the easy winning area K, forms a substantial side big winning opening 17, and the entire length of the actual side winning prize port 17 is substantially extended to a winning line segment N longer than that. It will be done. That is, according to the present embodiment, it is possible to substantially increase the side special winning opening 17 without actually opening the side special winning opening 17 and increasing the size of the slide door 17T.

  In addition, the game ball that has flowed down the first flow area 22M corresponding to the L-shaped vertical side of the L-shaped flow area 22B and entered the easy winning area K falls at a relatively high speed and rolls. Although the side big prize opening 17 is arranged in the downstream part of the rolling path 35, the game ball is prevented from strongly colliding with the slide door 17T and slides. It becomes possible to prevent malfunction of the door 17T.

  Further, since the side big winning opening 17 is arranged downstream from the intersection of the tangent line of the arc portion 24E and the rolling path 35, the game ball flowing down the arc passage 37 is guided by the arc portion and is rolled. 35 can fall to the upstream side from the side big winning opening 17. As a result, the game ball that has flowed down the column 36 can also win the side big prize opening 17, and the game ball flowing down the arc passage 37 can be interested.
