Red Stick Roller Derby plays flat track roller derby according to the latest rules and clarifications from the Women's Flat Track Derby Association.
You can download the latest full ruleset on the WFTDA web site.
The objectives of roller derby are relatively simple. Each team fields a single point scoring skater ("Jammer") whose object is to lap as many opposing skaters as they can.
The remaining skaters who aren't scoring points work both on offense and defense at the same time -- to block the opposing Jammer and to clear a path for their own Jammer.
Well-played roller derby requires agility, strength, speed, control, peripheral vision, communication, and teamwork.
