Rules to play 9 ball Pool
One person is chosen to shoot first, by breaking the rack. Usually this is determined by flipping a coin, or by lagging, especially in professional tournaments in the case of the latter, or it may be ruled by the authority in charge, the sponsor or the players themselves that the winner or loser of the previous game will always shoot first in the next rack. As with most pocket billiard games, the base of the cue ball must be behind the head string for the break shot. If the player who breaks fails to make a legal break, the opponent can either demand a re rack and become the breaker, or continue to play as if it had been an ordinary foul, depending upon the rules of the event. If the breaker pockets a ball and commits no foul, it remains the breakers turn. If the breaker pockets the 9 ball on the break (without fouling), this is an instant win.
