PROBLEM TO BE SOLVED: To provide a practical game machine which enables a player to change a game ball release position by his own skill. SOLUTION: A pachinko ball is released into a game area 70 from a launch passage 63 without passing through an underpass 67 when a pachinko ball launch force is weak and when the pachinko ball launch force is strong, the pachinko ball is released into a game area 70 from the launch passage 63 through the underpass 67. Consequently, since a player can change a pachinko ball release position by adjusting the amount of operation of a launch handle, the possibility of technical interference is increased. Since a pachinko ball is launched into the underpass 67 from the launch passage 63 by the launch force of a launch mechanism, the frequency of passage of the same pachinko ball through the underpass 67 is restricted to one time. Consequently, since it becomes easy to compute the percentage of winning of a pachinko ball in a special pattern start opening 99 or the like, practicality is improved. COPYRIGHT: (C)2006,JPO&NCIPI
