Nine-ball in the context of "U.S. Open Nine-ball Championships"

Pool is a series of cue sports played on a billiard table. The table has six pockets along the rails, into which balls are shot. Of the many different pool games, the most popular include: eight-ball, blackball, nine-ball, ten-ball, seven-ball, straight pool, one-pocket, and bank pool. Eight-ball is the most frequently played discipline of pool, and it is often thought of as synonymous with "pool".

The generic term pocket billiards is sometimes also used, and favored by some pool-industry bodies, but is technically a broader classification, including games such as snooker, Russian pyramid, and kaisa, which are not referred to as pool games. There are also hybrid games combining aspects of both pool and carom billiards, such as American four-ball billiards, bottle pool, cowboy pool, and English billiards.

The Color of Money is a 1986 American sports drama film directed by Martin Scorsese. It is the sequel to the 1961 film The Hustler. Like the previous film, The Color of Money is based on a novel by Walter Tevis.

The film stars Paul Newman reprising his role as "Fast Eddie" Felson, for which he won the Academy Award for Best Actor. The film also stars Tom Cruise playing a pool hustler, and features Mary Elizabeth Mastrantonio as the girlfriend of Cruise's character. The plot follows the trio as they hustle pool halls and make their way to a nine-ball tournament in Atlantic City. It received positive reviews from critics, though some considered it inferior as a sequel to The Hustler.

Eight-ball (also spelled 8-ball or eightball, and sometimes called solids and stripes, spots and stripes, bigs and smalls, big ones and little ones, or rarely highs and lows) is a discipline of pool played on a billiard table with six pockets, cue sticks, and sixteen billiard balls (a cue ball and fifteen object balls). The object balls include seven solid-colored balls numbered 1 through 7, seven striped balls numbered 9 through 15, and the black 8 ball. After the balls are scattered with a break shot, a player is assigned either the group of solid or striped balls once they have legally pocketed a ball from that group. The object of the game is to legally pocket the 8-ball in a "called" pocket, which can only be done after all of the balls from a player's assigned group have been cleared from the table.

The game is the most frequently played discipline of pool, and is often thought of as synonymous with "pool". The game has numerous variations, mostly regional. It is the second most played professional pool game, after nine-ball, and for the last several decades ahead of straight pool.

Ten-ball is a rotation pool game similar to nine-ball, but using ten balls instead of nine, and with the 10 ball instead of the 9 as the "money ball".

Although the game has existed since the early 1960s, its popularity has risen since the early 2000s as a result of concerns that nine-ball has suffered as a result of flaws in its fundamental structure, particularly the ease with which players can often make balls from the break. The World Pool-Billiard Association (WPA) standardized rules for ten-ball are very similar to those for nine-ball, but with key changes to increase the difficulty of the game. In contrast to nine-ball, it is slightly harder to pocket any balls on the break shot with the more crowded rack, the initial shooter cannot instantly win the game by pocketing the 10 on the break, all shots must be called, and performing a string of break-and-runs on successive racks is statistically more difficult to achieve.

Seven-ball is a rotation pool game with rules similar to nine-ball, though it differs in two key ways: the game uses only seven object balls as implied by its name, and play is restricted to particular pockets of the table. William D. Clayton is credited with the game's invention in the early 1980s.

Straight pool, which is also called 14.1 continuous and 14.1 rack, is a cue sport in which two competing players attempt to pocket as many object balls as possible without playing a foul. The game was the primary version of pool played in professional competition until it was superseded by faster-playing games like nine-ball and eight-ball in the 1980s.

In straight pool, the player may call and attempt to pocket any object ball on the table regardless of its number or color until only one object ball and the cue ball remain, at which point the other fourteen balls are re-racked. At this point, play resumes with the objective of pocketing the remaining ball in a manner that causes the cue ball to carom into the rack, spreading out the balls and allowing the player to continue the run. The goal is to reach a set number of points that is determined by agreement before the game begins; traditionally 100 points is needed for a win, though professional matches may go higher. One point is scored by pocketing an object ball without a foul, while a point is deducted on a foul.
