NAPA 9-ball Pro rules are the same as standard NAPA 9-ball rules with the following exceptions:

1. Racking: 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, the 9-ball in the center of the diamond and the 2-ball at the rear point of the rack. All other balls must be placed in the diamond in random order without purposeful or intentional pattern.
   1. Local League Operators have the option to require that the 9-ball be racked on the foot spot instead of the 1-ball. The 1-ball would still remain at the apex of the diamond rack, however, the 9-ball would be placed on the spot instead of the 1-ball.
   2. Local League Operators can also establish a "break from the box" rule as used in high level pool. 
2. 9-ball on break does not count as a win - 9-ball spots immediately - breaker keeps shooting.
3. Alternating breaks. No Rackless Match Bonus Point.
4. You can’t cheese the 9-ball for the win. It must be the last ball to drop in order to win.
5. You can, however, purposely pocket the 9-ball (by CALLING it) and keep shooting as long as you shoot the lowest numbered ball on the table first. After performing this shot, 9-ball spots immediately, and shooter keeps shooting.
6. Rack your own.
7. Players will have a completely separate CueSpeed 9-Ball Pro Rating for this format.
   
   9-BALL OPTION
8. If, while shooting at the 9-ball, the 9-ball falls into any pocket OTHER than the called pocket, the opponent has the option to play the 9-ball or hand the shot back to the original shooter.
   
   THREE-FOUL RULE OPTION
9. The NAPA local league operator has the right to enable the three-foul rule option in 9-ball Pro leagues. The three-foul rule causes a player to lose the game being played if the player commits three consecutive fouls without making a legal shot in between those fouls.
   1. The non-shooter must verbally announce and inform the shooter that he/she has committed their 2nd foul before the 3rd foul can be called for a loss of rack.
   2. If the non-shooter fails to notify the shooter of their 2nd foul the 3-Foul Win can not be taken and all fouls must reset back to zero (0) for the shooter.
   3. Committing a foul on the break is considered the first foul.
   4. If three-foul rule option is enabled for your league, shooters gain one bonus point on their score card for each game they win by the three-foul rule in their matches.
