PROBLEM TO BE SOLVED: To prevent frequent entrance of balls into a winning hole adapted for keeping the right to win, in an image type game machine, although no ball is shot into a specific area in a game area while the right is admitted. SOLUTION: In a game machine using image display in which items regarding a game, such as winning/losing (determining whether or not a ball has entered a winning hole) and jackpot/blank (determining whether or not a jackpot is admitted), are determined depending on the timing of shooting of a ball, when the condition under which the right to win is admitted is maintained if a ball is driven into the right area of a game-board image at the occurrence of a right-affording condition, whether or not a ball can enter a winning hole (the rate at which balls enter the winning hole) in order to maintain the right is determined, with a winning rate differing between when the ball is shot into the right area of the game board image (when route L13 is selected) and when the ball is shot into the left area of the game board image (when route L1 is selected). |
