- The Jammer: The star of the show if you will. This skater has a star helmet cover and scores all the points for her team. She's quick and agile, and covets that Lead Jammer status.
- The Pivot: Skater with a striped helmet cover. This skater sets the pace of the pack and is often called the “last line of defense.” The brains of the operation!
- The Blocker: You won't catch her with a helmet cover, but she can and will knock down whomever she can to make sure her jammer gets through the pack first.
Scoring is quick and the hits are crushing, so try not to blink! Five players from each team line up on the track: one Jammer (star cap), one Pivot (stripe cap) and three blockers (no cap). One whistle blows to start the Blockers and Pivots (a.k.a. the "Pack") and the Jammers. The first Jammer to make it through the Pack is named Lead Jammer, which gives her the right to end the play (or "Jam") at any time. On the next pass, both Jammers start scoring points for each player on the opposing team they pass. Pivots and blockers from the opposing team try to hold her back or knock her down, while her own team tries its best to make holes for her to slip through. It's offense and defense at the same time-- you'll have to see it to believe it!
