In-context commentary by pool pro Jerry Forsyth.A free ball is a player-nominated substitute for the ball "on" when a player becomes snookered as the result of a foul committed by the opponent. [1] The snooker is considered illegitimate in this case, and the affected player is allowed to nullify it by nominating any object ball as being "on" for the first shot of their turn. Once the free ball shot is taken legally, the game continues normally; however, if the player who committed the foul is asked to play again, a free ball is not granted.
