The rules governing the break shot are the same as for other shots except:
a. The breaker must strike the 1 ball first and either pocket a ball or drive at least four numbered balls to the rail.
b. If the cue ball is pocketed or driven off the table, or the requirements of the opening break are not met, it is a foul, and the incoming player has cue ball in hand anywhere on the table.
c. If on the break shot, the breaker causes an object ball to jump off the table, it is a foul and the incoming player has cue ball in hand anywhere on the table. The object ball is not respotted (exception: if the object ball is the 9 ball, it is respotted).
