Dodgeball is a children’s game that requires a large, soft rubber ball, the size of a volleyball or beachball, and several players. A popular version is circle dodge: in one variation the players form a circle about 30 feet in diameter and throw the ball, trying to hit a single player, or an equal number of players, within the circle. If a dodger within the circle is hit, he is out of the game; if the dodger manages to catch the ball, the thrower is out of the game and the dodger who caught the ball can try to hit a player on the outside circle. The game goes on until all the players but one have been hit.
