Kickback

Entertainment / Bowling / Kickback: Vertical division boards between the sides of the lanes at the pit end. On many hits the pins can bounce off the kickbacks and knock down more pins; see also sidewalls. Variations: Loose kickback means that there is not much rigidity to the sides, this causes the force of the pins to be absorbed easier resulting in less movement/bounce of the pins back onto the pin deck; Tight kickbacks means very solid rigid sides resulting in more bounce of the pins; desirable for higher scores.
