Nine-ball is a discipline of the cue sport pool. The game's origins are traceable to the 1920s in the United States. It is played on a rectangular billiard table with pockets at each of the four corners and in the middle of each long side. Using a cue stick, players must strike the white cue ball to pocket nine colored billiard balls, hitting them in ascending numerical order. An individual game is won by the player pocketing the 9-ball. Matches are usually played as a race to a set number of racks, with the player who reaches the set number winning the match.
