Snooker

Snooker is the most popular billiards game in Britain and the countries that were once part of the British Empire. The typical snooker table is 2 by 4 m (6 by 12 ft) and has six narrow pockets with rounded openings. Twenty-two balls are used: 15 red balls, 6 balls of various colors (in the United States these balls are numbered 2 through 7), and 1 cue ball. Players score points by pocketing red balls and colored balls alternately. When pocketed, the red balls remain out of play, while the other balls are returned to the table to assigned spots. When the reds are gone, the colored balls are pocketed in numerical order. Red balls are worth 1 point, the others are worth varying amounts depending on their color (or number). A player also scores points when an opponent fails to hit balls in the proper sequence.

RULES OF SNOOKERS


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. 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 2, green 3, brown 4, blue 5, pink 6, black 7. 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.
One game, from the balls in their starting position until the last ball is potted, is called a frame. A match generally consists of a predefined number of frames and the player who wins the most frames wins the match overall. Most professional matches require a player to win five frames, and are called 'Best of Nine' as that is the maximum possible number of frames. Tournament finals are usually best of 17 or best of 19, while the World Championship uses longer matches – ranging from best of 19 in the qualifiers and the first round proper, up to 35 frames in length (first to 18), and is played over two days.
Professional and competitive amateur matches are officiated by a referee who is the sole judge of fair play. The referee also respots the colours on to the table and calls out how many points the player has scored during a break. Professional players usually play the game in a sporting manner, declaring fouls the referee has missed, acknowledging good shots from their opponent, or holding up a hand to apologise for fortunate shots.
