Bowling is a sport wherein a heavy ball is rolled down a lane to knock down pins on the different finish. The variety of pins knocked down determines the rating for every body. A body is a set of two rolls, apart from the tenth body, which has three rolls.
The purpose of bowling is to knock down all ten pins with as few rolls as potential. A strike is when all ten pins are knocked down with the primary roll. A spare is when all ten pins are knocked down with two rolls. A gutterball is when the ball goes into the gutter on both facet of the lane.
