Boccia matches are held in indoor halls, on specially marked courts. The players’ aim is to throw their colored leather balls, which may be either red or blue, as close as they can to a white target ball, which is called the “jack”. The match begins with the spinning of a coin by the referee. The winning side chooses whether to play with red or blue balls. The side with the red balls initiates the first end (round) by throwing the “jack” first and then the first red ball. The ball can be propelled by the hand, the foot, or by using an assistive device when players have a severe locomotor disability that affects all four extremities. The match continues with the opponents taking turns in trying to throw their balls as closes as possible to the “jack”. At the end of each end the referee measures the distances of the balls that are closest to the “jack”, points are awarded accordingly and are accumulated to declare the winner.
