[Problem to be solved by the present invention] In the conventional winning device,
Since the game balls falling from above are guided to the respective openings in the opening by the opening / closing plate, the probability that the game balls winning in the opening pass through the specific opening is determined when the game balls fall on the opening / closing plate. Depends on the falling position of

On the other hand, when a game ball passes through a specific drop hole in the opening, a large number of game balls are returned to the player as prize balls. There is a rule that the probability that a ball will pass through a particular drop must be limited to a certain value or less.

Therefore, conventionally, a plurality of obstacle nails are arranged on the upper side of the winning device so as to limit the probability that a game ball enters a specific drop to a certain level or less. The probability is kept below a certain level by the arrangement and the adjustment of the distance between the obstacles.
