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 twenty-two balls, comprising a white
cue ball, fifteen red balls, and six other balls—a yellow, green, brown, blue, pink, and black—collectively called the colours. Using a cue stick, 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 time the opposing player or team commits a
foul. An individual
frame of snooker is won by the player who has scored the most points. A snooker
match ends when a player reaches a predetermined number of frames.
