The apex ball should be aligned at the foot spot on the table, with the bottom of the break formation aligned parallel with the foot of the table. The rest of the rack should be random, except for the bottom corners of the triangle - one corner ball should be a solid, and the other a stripe. The RackĨ-Ball is located in the center - two rows from the top and two rows from the bottom. The 8-Ball does not belong to either group. The object balls are divided into two separate groups - solids (balls numbered 1 through 7) and stripes (balls numbered 9 through 15). 8-Ball is played with a cue ball and 15 object balls.
