Boules is a sport in which athletes throw or roll heavy balls (boules) as close as possible to a small target ball. The aim of the game is to place one’s boules as near as possible to a target (called the jack). The opponent attempts to place their boules close to this jack or to remove the boules that prevent them doing so. The boules are thrown (palm down) and are metal. There are two disciplines of Boules offered in The World Games: Lyonnaise and Pétanque.
