PURPOSE: To provide a hole-in-one discriminating apparatus which can effectively give an impression of hole-in-one to a player by combining and arranging a hole-in ball jumping apparatus which operates when hole-in-one is made, flashlights disposed around a green, and an apparatus for operating a ball removing stick which rotates on the green.

CONSTITUTION: When a ball hit from a player's box 3 bound into a hole cup 2 on a green 1 for hole-in-one, a hole-in ball jumping apparatus including a driving apparatus which jumps the ball installed in the hole cup 2 operates through a ball detecting apparatus and the ball is jumped from the hole cup 2. Simultaneously, an announce signal operating apparatus 7 announces hole- in-one over a loudspeaker 8 arranged in a front (reception) desk or the player's box, flashlights 9 arranged around the green go on and off, so that the player movingly knows hole-in-one. After that, a ball removing stick 10 rotates, thereby removing the ball on the green.
