Spinning a bowling ball is a technique that can greatly improve your accuracy and control on the lane. By putting spin on the ball, you can cause it to hook or curve towards the pins, making it much easier to hit your target. There are two main types of spin: backspin and topspin.
Backspin is created by rolling the ball with your fingers behind the center of the ball. This causes the ball to rotate backward as it rolls down the lane, which in turn causes it to hook towards the pins. Topspin is created by rolling the ball with your fingers in front of the center of the ball. This causes the ball to rotate forward as it rolls down the lane, which in turn causes it to curve away from the pins.
