PROBLEM TO BE SOLVED: To freely expand or contract a game ball entrance, and to dispose both a symbol variation start winning hole and a jackpot winning hole in a saved space without being affected by the enlargement of a symbol variable display device, and without narrowing the openings. SOLUTION: The game ball guiding device includes a pair of a left guiding member 31 and a right guiding member 32 for forming the game ball entrance and for guiding game balls to winning holes by expanding or contracting the entrance; a left driving means 40a for opening/closing the left guiding member 31; a right driving means 50a for opening/closing the right guiding member 32; and a control means for individually controlling the left driving means 40a and the right driving means 50a to be in an unopened state in which both the left guiding member 31 and the right guiding member 32 are unopened, or in a one-side opened state in which either the left guiding member 31 or the right guiding member 32 is opened, or in a both-side opened state in which both the left guiding member 31 and the right guiding member 32 are opened.
