The initial rack

In the initial rack in straight pool, the fifteen object balls are racked in a triangular rack, with the center of the apex ball placed over the foot spot. Traditionally, the 1 ball is placed at the rack's right corner, and the 5 ball placed at the rack's left corner, although this is not an official rule. Other balls are placed at random and must touch their neighbors. However, it is considered courtesy by some to place a stripe ball at the rack's apex.

Unlike in most pool games, where pocketing a ball and spreading the balls is the aim on the break, the object in straight pool's standard initial break shot is to leave the opponent with a safety. This is because the call-pocket rule includes the break shot.

On the break, either a ball must be pocketed in a designated pocket or the cue ball and at least two additional balls must touch a rail. The failure to accomplish one of these two options results in a foul. Fouling on the initial break results in a special penalty of a loss of 2 points. In addition, the opponent has the choice either of accepting the table in position, or alternatively of having the balls re-racked and requiring the offending player to repeat the opening break.
