A frame supports as a base a plurality of goals rotatably. The goals are arranged asymmetrically with respect to the vertical axix from the view point of a player. Some goals hide others. When a ball shot by a player hits the frame of a goal. Then the goal rotates to guide the ball out of the goal. Unless a ball is directed to the central portion of the frame of the goal without hitting the frame, the possibility is low that the ball drops in the goal.
