Abstract: A game goal apparatus that is intended to be played within a swimming pool which uses a substantially planar backboard at opposite ends of the swimming pool. Each backboard is designed to be used in conjunction with a water polo ball. Each backboard includes a through opening which may connect with a net mounted on the backboard to guide the ball when the ball passes through the through opening to be deposited on the water directly adjacent the rear surface of the backboard. The backboard is to be mounted on a frame which may be located within the water of the swimming pool. The backboard is tilted to assume an inclined position so that upon the ball striking the surface of the backboard it rebounds in an upward direction away from the surface of the water of the swimming pool. The goal apparatus may be collapsible when not in use.
