Two or two teams.


The table should be either 4 feet by 8 feet, 4 1/2 feet by 9 feet, 5 feet by 10 feet, or 6 feet by 12 feet without pockets. Markings include spots in the center of the head string, foot string, and center string. There should be two additional spots on the head string six inches on either side of the head spot.


Three balls are used - one red bell, one white ball without spots and one white ball with spots (or a yellow ball).

For the break shot, place the red ball on the foot spot, the opponents cue ball on the head spot, and the shooters cue ball on the head string within six inches of the center spot. For the break to be legal, The cue ball must contact the red ball first.


  1. For any shot other than break shots, the cue ball may contact either object ball first.

  5. If a ball leaves the table spot them in the following order red ball, cue ball of offending player, cue ball of incoming player. The first ball is placed on the foot spot (if it is available), the second on the head spot (if it is available), and the third on the center spot.
