The game of Flat Track Roller Derby is played on a flat, oval track. Play is broken up into two 30-minute periods, and within those periods, into units of play called “Jams,” which last up to two minutes. There are 30 seconds between each Jam.
During a Jam, each team fields up to five Skaters. Four of these Skaters are called “Blockers” (together, the Blockers are called the “Pack”), and one is called a “Jammer.” The Jammer wears a helmet cover with a star on it.
The two Jammers start each Jam behind the Pack, and score a point for every opponent they lap, each lap. Because they start behind the Pack, they must get through the Pack, then all the way around the track to be ready to score points on opposing Blockers.
Roller derby is a full-contact sport; however, Skaters cannot use their heads, elbows, forearms, hands, knees, lower legs, or feet to make contact to opponents. Skaters cannot make contact to opponents’ heads, backs, knees, lower legs, or feet.
Play that is unsafe or illegal may result in a Skater being assessed a penalty, which is served by sitting in the Penalty Box for 30 seconds of Jam time.
The team with the most points at the end of the game wins.
