Also winner. A shot in which the cue ball is used to pot another ball. In snooker and most pool games doing this is known as potting, pocketing or sinking the targeted ball.

Whether the ball is an object ball or an opponent's cue ball depends upon the type of game (some have two cue balls). The move will score points in most (but not all) games in which hazards (as such) apply, such as English billiards (in which a "red winner" is the potting of the red ball and a "white winner" the potting of the opponent's cue ball, each worth a different amount of points).
