Ten-pin bowling (or more commonly, just "bowling") is a competitive sport in which a player (the “bowler”) rolls a bowling ball down a wooden or synthetic (polyurethane) lane with the objective of scoring points by knocking down as many pins as possible.The 41.5-inch (105 cm) wide, 60-foot (18 m) lane is bordered along its length by "gutters”—semicircular channels designed to collect errant balls which also pose an obstacle to advanced bowlers, because a straight ball cannot be rolled on a regulation lane at the angle required to consistently carry (knock down) all ten pins for a strike.
Most skillful bowlers will roll a more difficult-to-control hook ball to overcome this. There is a foul line at the end of the lane nearest to the bowler: if any part of a bowler’s body touches the lane side of this line after the ball is delivered (rolled), it is called a foul and any pins knocked over by that delivery are not scored.
(The bowler is allowed a shot at a new rack of ten pins if he fouled on the first roll of a frame.) Behind the foul line is an “approach” approximately 15 feet (5 m) long used to gain speed and leverage on the ball before delivering it. 60 feet (18 m) from the foul line, where the lane terminates, it is joined to a roughly 36-inch (91 cm) deep by 41.5-inch (105 cm) wide surface of durable and impact-resistant material called the "pin deck," where each rack of pins is set.

The bowler is allowed ten frames in which to knock down pins, with frames 1 through 9 being composed of up to two rolls. The tenth frame may be composed of up to three rolls: the bonus roll(s) following a strike or spare in the tenth (sometimes referred to as the eleventh and twelfth frames) are fill ball(s) used only to calculate the score of the mark rolled in the tenth.
