Ten-pin bowling ramp in which a bowler will use two hands and push the ball down the ramp onto the lane. There are three widely recognized delivery styles used while the ball is released onto the lane. (See article: Bowling form.) These are the "stroker", "cranker" and "tweener" styles. Lesser used (and newer) styles include "no-thumb" and "two-handed". Strokers often keep their shoulders square to the foul line and their backswing generally does not go much above parallel to the ground. This type of delivery reduces the ball's rate of revolution, thus decreasing its hook potential and hitting power. Strokers rely on
Hook (bowling) or the 10-pin if the ball was just slightly right of the head pin. A hook ball can create strikes with less precise hits at the pocket. A hook ball can also help the bowler shape the shot on challenging oil patterns. In other games of bowling, such as duckpin bowling or candlepin bowling, a hook is virtually non-existent for experienced bowlers since the ball is much smaller than in ten-pin bowling, and rolls too fast to the pins to allow a hook to develop. There are two ways to produce a hook. The first method involves bowling technique. At
