Bowling refers to a series of sports or leisure activities in which a player rolls or throws a bowling ball towards a target. It is one of the major forms of throwing sports. In pin bowling variations, the target is usually to knock over pins at the end of a lane. In target variations, the aim is usually to get the ball as close to a mark as possible.
Rules of play. A game of bowling consists of ten frames. In each frame, the bowler will have two chances to knock down as many pins as possible with their bowling ball. In games with more than one bowler, as is common, every bowler will take their frame in a predetermined order before the next frame begins.
