In International Snooker rules, a 4-point penalty is assessed if the cue ball jumps or leaves the table surface.
In Pocket Billiards, according to the Billiard Congress of America, a jump shot is only penalized under one of two scenarios; a) if the ball is intentionally jumped over an obstruction (ball or rail) or b) if the cue ball is intentionally struck with anything on the cue but the tip, causing the ball to jump. The first infraction in a match carries a warning; a second infraction in the same match results in forfeiture.
In 8-Ball, during general play with no formal referee, a jump( masse') shot is legal unless the obstructing ball is not a legal next ball and is touched by cue ball or cue. The penalty is treated as a scratch.
In Carom Billiards, jump balls are spotted.
