Snooker is a cue sport that is played on a huge baize-covered table with pockets in each of the four corners and in the middle of each of the extended side cushions. A regulation (full-size) table is 12 ft × 6 ft (3.6 m x 1.8 m). It is played by a cue and snooker balls: one white cue ball, 15 red balls worth one point each, and six balls of different colours yellow (2), green (3), brown (4), blue (5), pink (6) and black (7).A player (or team) wins a enclose (individual game) of snooker by scoring more points than the opponent(s), using the cue ball to pot the red and colored balls. A player wins a match, when a certain number of frames have been won.

Snooker is mainly popular in many of the English-speaking and Commonwealth countries, and in China, with the top expert players attaining multi-million pound profession earnings from the game.
