In order to win the game, the player first designates which pocket the 8 ball will be pocketed into and then successfully pockets the 8 ball into that pocket. At the start of the game, the red balls are racked into a tightly packed equilateral triangle and the six colours are positioned at designated spots on the table. The table has six pockets, one at each corner and one at the centre of each of the two longer side cushions. A snooker ball set consists of twenty-two unmarked balls: fifteen reds, six colour balls, and one white cue ball. A foul can occur for various reasons, such as sending the cue ball into a pocket, or failing to hit the object ball. All points scored in the break before the foul was committed are awarded to the striker, but no points are scored for any ball pocketed during the foul shot.

A traditional snooker scoreboard resembles an abacus and records the points scored by each player for the current frame in units and twenties, as well as the frame scores. If the scores are equal when all of the object balls have been potted, the black is used as a tiebreaker. When the final ball is potted, the player with the most points wins the frame. Failure to make contact with a red ball constitutes a foul, which results in penalty points being awarded to the opponent. The cue ball may contact an object ball directly or it can be made to bounce off one or more cushions before hitting the required object ball. The cue ball is placed inside the "D" ready for the break-off shot. If the referee has also called a "miss"-meaning that the referee has deemed the opponent not to have made their best possible attempt to hit the object ball-the player has the option of having the balls replaced to their original positions and forcing the opponent to play the shot again.

Professional and competitive amateur matches are officiated by a referee, who is charged with ensuring the proper conduct of players and making decisions "in the interests of fair play". Advanced variants of association croquet give further penalties to dissuade skilled players from running every hoop with a ball on a single break, while handicap versions give weaker players chances to continue play after making an error. Internationally, the World Pool-Billiard Association and the World Eightball Pool Federation both publish rules and promote events. The alternative is the cheaper MDF (wood) bed pool table. When a player commits a scratch, their opponent often receives what’s known as "ball-in-hand." This penalty grants the non-offending player the ability to place the cue ball anywhere on the table. If the cue ball finishes in contact with an object ball, a touching ball is called. The tip of the cue must only make contact with the cue ball and is never used for striking any of the reds or colours directly.

Since the cue tip hits the ball off-center, physics states that the ball will deflect or "squirt" in the opposite direction. The nap affects the speed and trajectory of the balls, depending on the direction of the shot and whether any side spin is placed on the ball. Even if the cue ball is struck in precisely the same manner, the effect of the nap will differ according to whether the ball is directed towards the baulk line or towards the opposite end of the table. Accordingly, learn how to position your feet and body for optimal cue ball control. The game continues until every red ball has been potted and only the six colours and the cue ball are left on the table. Each player has a cue stick (or simply a "cue"), not less than 3 ft (91.4 cm) in length, which is used to strike the cue ball.
