PROBLEM TO BE SOLVED: To provide a game machine preventing breakage of a stage part by varying the mode of guiding the game ball using a warp device to reduce the speed of the game ball flowing into the warp device. SOLUTION: In the warp device 20, the inside diameter of a ball flow passage 22 is made larger than a minimum size that allows only one game ball to pass through the passage. Mounting bosses 77, 78 for mounting the warp device 20 to a center case 10 are formed to project into the ball flow passage 22, thereby varying the movement of the game ball flowing down in the ball flow passage 22.
