Jammers wear a star on their helmets and are the scoring players for each team. Jammers attempt to pass the opponents as many times as possible per jam by sprinting around the track and lapping the pack.
Blockers are simultaneously focused on stopping the opposing Jammer from passing them and assisting their Jammer to pass the opposing team’s Blockers. The pack is formed by the largest group of Blockers with players from each team on the track.
The Pivot is the Blocker that wears the stripe on their helmet cover. They are the only Blocker that is allowed to accept a star pass from the Jammer, thus becoming the new Jammer and gaining the ability to score points.
Flat track roller derby is a fast-paced, full-contact team sport that requires speed, strategy, and athleticism. Two 15-skater teams play two 30-minute periods. Each period consists of multiple “jams.” Each jam is an opportunity for both teams to score points, and ends after 2 minutes or when the Lead Jammer calls off the jam.
It is legal for a skater to block opponents with their hips, rear, and shoulders. It is not legal to block to the back, to trip, to elbow, or to back-talk officials. Players committing illegal actions are penalized 30 seconds and their team plays short for that time.
