Sometimes bowlers will use head games to mess with other people if they see they are bowling well.
The goal is to knock ten down with as few shots as possible. Carry is about the angle the ball is entering the pocket, kick plate strength, flat gutter installs, alot of different variables that doesn't always account for correct ball roll through the pins on off pocket hits.
