PROBLEM TO BE SOLVED: To provide a game machine, when a game ball flows down a game area, improving a probability of ball entry in a winning hole on the basis of an initial design probability.SOLUTION: The game machine includes, in a game area 4a on which game balls flow down: game pins N; a stage 20 causing a game ball received from the game area 4a to roll; and an operation-start winning hole 214 that uses entry of a game ball as a trigger of a lottery related to a jackpot. The stage 20 includes: release parts 221 and 227 that release rolling game balls from the stage 20; a general winning hole 225 that uses entry of a game ball as a trigger to put out prize balls; a first pathway 225a capable of rolling the game ball towards the general winning hole; second pathways 221a and 226 capable of rolling the game ball towards the operation-start winning hole or the release parts; and guide parts 211, 212, and 213 that can guide a game ball in such a manner as to make a rolling probability of the received game ball onto the first pathway 225a higher than a rolling probability thereof onto the second pathways 221a and 226.SELECTED DRAWING: Figure 3 |
