What is Roller Derby?
Roller Derby is played on a flat oval track with two teams of five players. A team consists of four blockers and a jammer. The blockers with the stripe on their helmets are called pivots and they control the speed of the pack. The jammer has a star on her helmet and is the point scorer. The team who scores most points at the end of the game is the winner.
The aim of the jammer is to make her way through the pack, scoring points for each opposing team member they pass.
Blockers must try to stop the opposing jammer from getting through, as well as assisting their jammer through the pack.
Players receive penalties by committing fouls such as using hands or elbows for blocking. These sorts of naughties send a skater to the penalty box for thirty seconds. Teams with skaters in the penalty box skate with less players on the track, thus are at a disadvantage. After seven visits to the box, skaters are ejected from the game.
