Boccia is traditionally played on natural soil and asphalt courts 27.5 metres (90 ft) in length and 2.5 to 4 metres (8.2 to 13.1 ft) wide. Boccia balls can be made of metal or various kinds of plastic & are spherical and have no inbuilt bias. A game can be conducted between two players, or two teams of two, three, or four. A match is started by a randomly chosen side being given the opportunity to throw a smaller ball, the jack down the court.
The side that first attempted to place the jack is given the opportunity to bowl first. Once the first bowl has taken place, the other side has the opportunity to bowl. From then on, the side which does not have the ball closest to the jack has a chance to bowl, up until one side or the other has used their four balls. At that point, the other side bowls its remaining balls. The team with the closest ball to the jack is the only team that can score points in any frame. The scoring team receives one point for each of their balls that is closer to the jack than the closest ball of the other team. The length of a game varies by region but is typically from 7 to 13 points.
Players are permitted to throw the ball in the air using an underarm action. This is generally used to knock either the jack or another ball away to attain a more favourable position. Tactics can get quite complex when players have sufficient control over the ball to throw or roll it accurately.
