Snooker 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: a white cue ball, 15 reds and six colours — yellow, green, brown, blue, pink and black. Using a snooker cue, players take turns to strike the cue ball to pot other balls in a defined sequence, scoring points for each pot and for fouls committed by the opposing player. 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.
