Rack

Also called: Triangle, Diamond rack, Racking

How do you rack in 8-ball and 9-ball?

A rack is the frame used to set the balls for the break — a triangle for 8-ball (15 balls) and a diamond for 9-ball (9 balls). 'Rack' also means a single game, as in 'he ran three racks'.

Step by step

  1. 18-ball: apex ball on the foot spot, 8-ball in the center of the third row, one solid and one stripe in the back corners.
  2. 29-ball: 1-ball on the foot spot, 9-ball in the middle of the diamond, other balls in random order.
  3. 3Push the balls forward and tap the back so every ball is frozen, then lift the rack straight up.

In more detail

A tight rack, with every ball frozen to its neighbours, transfers energy evenly and gives a bigger, more predictable spread. Gaps make the rack 'dead' and the break weaker. Many tournaments now use templates instead of racks for consistent tightness.

People also ask

Does a tight rack really matter?

Yes. A loose rack absorbs energy and produces clusters, making a run-out much harder.
