PROBLEM TO BE SOLVED: To provide a pachinko machine permitting easy removal of dust accumulated between ribs in a failure hole guide part. SOLUTION: The failure hole guide part 30 is composed of a base bottom wall part 33 defining a game area 9 just under the front of a failure hole 19, and ribs 35 in the front/rear direction raised on the upper face of the base bottom wall part 33. The upper face of the ribs 35 is inclined backward and downward and the upper face of the base bottom wall part 33 is inclined forward. With this structure, a game ball x can be guided to the failure hole 19 by the guiding action of the upper face of the ribs 35 and the dust accumulated between the ribs 35 can be easily scraped out forward by the guiding action of the upper face of the base bottom wall part 33.
