Jammers: These skaters are designated by a star on their helmets. They are the ones who score points by working their way through the pack and lapping opposing players.
Pivots: These skaters are designated by a large stripe on their helmets. Responsible for keeping the pack together and having an overview of what the pack is doing. They signal strategies to their teammates and also work as a blocker.
Blockers: Block the opposing Jammer while simultaneously trying to get their Jammer through.
The Pack: The large group of blockers on the track. If a skater falls 20 feet from the pack, they cannot engage an opponent and must yield to the opposing Jammer and rejoin the pack.
