Boccia is designed for disabled athletes and can be played by individuals, pairs or teams of three. Players take it in turns to throw leather balls, always red or blue, as close as they can to a white target ball or ""jack"". The balls can be moved with your hands, feet or an assistive device. After each round, the ref sees whose balls are closest to the jack. One point is given for each player's ball that got closest to the jack. PRO FACT Boccia is one of the only Paralympic sports that has no equivalent in the Olympics.
