PROBLEM TO BE SOLVED: To provide a game machine capable of improving a probability of balls entering a ball entry hole located on the lower side by stabilizing a falling direction of a game ball via a stage.SOLUTION: A high-probability release passage 420 formed at a central part of a rolling stage is formed into an inverse-U shape with a pursed-lips-like profile, and includes a protrusion 422 on a central part at an innermost part in the depth direction corresponding to a bottom of the U shape, and other protrusions 424 and 426 at both two sides thereof at substantially equal intervals from the protrusion. The three protrusions in total are continuously formed from an entrance to an exit of the high-probability release passage 420 so as to narrow a movable range of a game ball passing therethrough and limit a position of a centroid within a prescribed range. This configuration causes a game ball to fall toward an introduction port 202 of a three-way distribution device 200 located immediately thereunder in a stable state in a stage of leaving the high-probability release passage 420 so as to make the game ball win at a high probability.SELECTED DRAWING: Figure 11 |
