So What is Roller Derby?

Here is a little bit of the basics to get you started! Two 14-skater teams play two 30-minute periods. Each period consists of multiple ‘jams.’ Each jam is an opportunity for both teams to score points. A jam can last up two minutes unless the Lead Jammer calls it off herself.

At the beginning of each jam, each team fields four Blockers and one Jammer.  Blockers attempt to take the position most advantageous for their Jammer while setting up to block the opposing Jammer.  Play starts with a single whistl e blast. During the first pass, the Jammer to pass all in-play Blockers in the pack legally is the Lead Jammer. Lead Jammer status is signaled by the officials blowing two short whistle blasts and point at the Lead Jammer.  In subsequent passes, Jammers earn 1 point for each opposing player they pass legally. The opposing Blockers will try to stop the Jammer, while helping their own Jammer through the pack.
