PROBLEM TO BE SOLVED: To provide a pachinko machine capable of increasing the feel of expectation to a big prize. SOLUTION: At a lower part of a variable display device, a stage 8 composed of a back stage 20 having a passage for game balls to roll extended right to left and a front stage 21 is provided. On the back stage 20, curved-surfaced irregularity parts 23, 24, and 25 are formed, so that action of the game balls is provided with variation. The recessed part 25 functions as a guide groove to the back stage 20. On the front stage 21, a guide groove 26 is formed to extend the guide groove 25. Winning probability of the game balls to a starting prize hole 9 becomes higher when the game ball rolls along the back stage 21 to reach the guide groove 25 to be guided to the guide groove 26. Close to both end parts of the front stage 21, partition walls 31 and 32 to guide the game balls toward the back stage 20 are provided, and partition walls 27-30 to guide the game balls toward a center part (in the direction of the guide groove 25) are provided between the back stage 20 and the front stage 21.
