The NAPA 8-ball format is a "call your pocket" league. Making a ball in an unintended pocket is considered slop and does not count. Calling a pocket is done by either, verbally announcing the designated pocket to the opponent or any shooter on the opposing team, or by pointing at the pocket with your hand or pool cue.

It is encouraged that all balls be specified vocally to your opponent along with their intended pocket. Obvious balls and their respective pockets do not have to be specified, however, when performing a bank shot, a kick shot, a jump shot, a masse shot, or a combo shot, the shooter must call his or her intended object ball and pocket.

If the shooter does not call his or her intended object ball and pocket when performing a bank shot, a kick shot, a jump shot, a masse shot, or a combo shot, it is a loss of turn and ball in hand for the opponent.

When calling your pocket, it is NEVER necessary to indicate details such as the number of cushions, banks, kisses, caroms, etc. Any ball pocketed on a foul remains pocketed, regardless of whether they belong to the shooter or the opponent.
