1.5 RACKING THE BALLS (9-BALL RULE)

The object balls (1-ball through 9-ball) are to be racked as tightly as possible in a diamond shape, with the 1-ball at the apex of the diamond and on the foot spot, and the 9-ball in the center of the diamond. All other balls should be placed in random order.

If, after the balls have been racked, all balls in the rack are not in contact one another, also known as a "loose rack", the shooter who is to break may request a re-rack. At which time the opposing shooter is to re-rack the balls so that all balls in the rack are properly contacting one another, also known as a "tight rack".
