9 Ball Pool and Billiards Rules
Nine ball is played with nine object balls numbered one through nine and the cue ball. The balls are played in ascending numerical order. The player legally pocketing the nine ball wins the rack.
Determining the Break
The player who wins the lag chooses who will break the first rack. (See Lagging to Determine Order of Play.)
Nine Ball Rack
The object balls are racked as tightly as possible in a diamond shape, with the one ball at the apex of the diamond and on the foot spot and the nine ball in the middle of the diamond. The other balls will be placed in the diamond without purposeful or intentional pattern.
Legal Break Shot
The following rules apply to the break shot:
Second Shot of the Rack - Push Out
If no foul is committed on the break shot, the shooter may choose to play a “push out” as his shot. He must make his intention known to the referee, and then rules Wrong Ball First and No Rail after Contact are suspended for the shot. If no foul is committed on a push out, the other player chooses who will shoot next.
If the shooter legally pockets any ball on a shot (except a push out, see Second Shot of the Rack – Push Out), he continues at the table for the next shot. If he legally pockets the nine ball on any shot (except a push out), he wins the rack. If the shooter fails to pocket a ball or fouls, play passes to the other player, and if no foul was committed, the incoming player must play the cue ball from the position left by the other player.
If the nine ball is pocketed on a foul or push out, or driven off the table, it is spotted. (See Spotting Balls.) No other object ball is ever spotted
If the shooter commits a standard foul, play passes to his opponent. The cue ball is in hand, and the incoming player may place it anywhere on the playing surface. (See Cue Ball in Hand.) The following are standard fouls at nine ball:
If a stalemate occurs the original breaker of the rack will break again. (See Stalemate.)
