Did four balls touch a side?
Well.......I suppose not. Then it's a foul.

(c) If the breaker pockets a ball and does not foul, he continues at the table, and the table remains open. (See 3.4 Open Table / Choosing Groups.)
(d) If no object ball is pocketed, at least four object balls must be driven to one or more rails, or the shot results in an illegal break, and the incoming player has the option of
(1) accepting the table in position, or
(2) re-racking and breaking, or
(3) re-racking and allowing the offending player to break again.
