PURPOSE: To provide a set of exercise tools for a game to throw a disk-shaped ball in a goal which is floating on the water by making the ball bounce on the water, to dissolve problems such as although swimming is highly evaluated as an exercise for whole body, many people stay away from water because they do not know how to swim, or there are only few varieties in water sports, and there hardly exists types of games by which a team play can be enjoyed.

CONSTITUTION: For the title game, two types of exercise tools, a disk-shaped ball 1 and movable goal post 7 are used. Scores are competed by throwing the disk-shaped ball 1 in the goal of the opposite team by making the ball bounce on the water by 4 to 10 members for one team. A goal keeper moves the goal post 7 which is floating on the water by pulling the goal post 7 by a rope 10 by himself/herself to prevent the opposite team from making points.
