Snooker is a cue sport played on a rectangular table covered with green cloth. It involves 21 balls: 15 red balls, 6 colored balls (yellow, green, brown, blue, pink, and black), and a white cue ball. Players use a cue stick to strike the cue ball, aiming to pot (sink) the balls into pockets located at the corners and sides of the table.

The game is played in turns, and players score points by potting balls in a specific sequence. The basic sequence is to pot a red ball first, followed by a colored ball, then another red, and so on. Each ball has a different point value, with red balls worth 1 point each and colored balls ranging from 2 to 7 points. The goal is to score more points than the opponent.

Snooker is known for its strategic depth, requiring both skillful shot-making and tactical play. The game continues until all the balls have been potted, and the player with the highest score wins
