Nine-ball (9-ball) is played with nine object balls numbered one through nine and a cue ball. On each shot, the first ball the cue ball contacts must be the lowest numbered ball on the table, but the balls need not be pocketed in order. If a shooter pockets any ball on a legal shot, he remains at the table for another shot, and continues until missing, committing a foul, or winning the game by legally pocketing the 9-ball. After a shooter misses, the incoming shooter must shoot from the position on the table left by the previous shooter, but after any foul the incoming shooter may start with cue ball in hand anywhere on the table. A match ends when one of the shooters has won the required number of games.
