Cue sport in the context of "Kaisa (billiards)"

Snooker (pronounced UK: /ˈsnuːkər/ SNOO-kər, US: /ˈsnʊkər/ SNUUK-ər) is a cue sport played on a rectangular billiards table covered with a green cloth called baize, with six pockets: one at each corner and one in the middle of each long side. First played by British Army officers stationed in India in the second half of the 19th century, the game is played with 22 balls, comprising a white cue ball, 15 red balls and six other balls—a yellow, green, brown, blue, pink and black—collectively called 'the colours'. Using a snooker cue, the individual players or teams take turns to strike the cue ball to pot other balls in a predefined sequence, accumulating points for each successful pot and for each foul committed by the opposing player or team. An individual frame of snooker is won by the player who has scored the most points, and a snooker match ends when a player wins a predetermined number of frames.

In 1875, army officer Neville Chamberlain, stationed in India, devised a set of rules that combined black pool and pyramids. The word snooker was a well-established derogatory term used to describe inexperienced or first-year military personnel. In the early 20th century, snooker was predominantly played in the United Kingdom, where it was considered a "gentleman's sport" until the early 1960s before growing in popularity as a national pastime and eventually spreading overseas. The standard rules of the game were first established in 1919 when the Billiards Association and Control Club was formed. As a professional sport, snooker is now governed by the World Professional Billiards and Snooker Association.

Nine-ball (sometimes written 9-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 (or rack) 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.

The game is currently governed by the World Pool-Billiard Association (WPA), with multiple regional tours. The most prestigious nine-ball tournaments are the WPA World Nine-ball Championship and the U.S. Open Nine-ball Championships. Notable 9-Ball players in the game include Luther Lassiter, Buddy Hall, Efren Reyes, Fedor Gorst, Earl Strickland and Shane Van Boening. The game is often associated with hustling and gambling, with tournaments often having a "buy-in" amount to become a participant. The sport has featured in popular culture, notably in the 1961 film The Hustler and its 1986 sequel The Color of Money.
