The game is called a bout. There is two 30 minute halves, within those halves there is smaller units called jams. Each jam can last up to 2 minutes. 15 skaters per team; rotate each jam.

The jammer wears a star helmet cover and is the only skater that is able to score points. Jammers score points by passing opposing blockers hip.

The blockers job is to prevent the opposing jammer from passing and scoring points. The blocker with the strip helmet cover is called the pivot. The pivot is a blocker that can become the jammer mid jam.
