Snooker

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

Snooker, generally regarded as having been invented in India by British Army officers, is particularly popular in many of the English-speaking and Commonwealth countries, with top professional players attaining multi-million pound career earnings from the game.

The object of the game is to score more points than the opponent by potting object balls in a predefined order. At the start of a frame, the balls are positioned as shown and the players take it in turns to hit a shot in a single strike from the tip of the cue, their aim being to pot one of the red balls and score a point. If they do pot at least one red, then it remains in the pocket and they are allowed another shot - this time the aim being to pot one of the colours. If successful, then they gain the value of the colour potted. It is returned to its correct position on the table and they must try to pot another red again. This process continues until they fail to pot the desired ball, at which point their opponent comes back to the table to play the next shot. The game continues in this manner until all the reds are potted and only the 6 colours are left on the table; at that point the aim is then to pot the colours in the order yellow, green, brown, blue, pink, black. When a colour is potted in this phase of a frame, it remains off the table. When the final ball is potted, the player with the most points wins.

Points may also be scored in a game when a player's opponent fouls. A foul can occur for numerous reasons, such as hitting a colour first when the player was attempting to hit a red, potting the cue ball, or failing to escape from "a snooker" (a situation where the previous player finished their turn leaving the cue ball in a position where the object ball cannot be hit directly). Points gained from a foul vary from a minimum of 4 to a maximum of 7 if the black ball is involved.
