Some dodgeballs are made of rubber. Some leagues allow the use of multiple sizes of dodgeballs in a single match, while others use one standard size for all ball.Any number of dodgeballs may be used in a game, but between five to ten is common. Exceptions are usually made if a court is particularly small or if many people participate.
