What is chicago style roller derby?

Chicago-style roller derby, also known as "windy city derby," is a variant of roller derby that originated in Chicago, Illinois in the 1930s. It is a full-contact sport played on roller skates, with two teams of five players competing on an oval-shaped track.

In Chicago-style roller derby, there is no lead jammer, and the game is played with a single, continuous 30-minute period. Each team has a jammer, who is the player responsible for scoring points by lapping members of the opposite team. The other four players on each team are blockers, whose job is to block opposing players and assist their team's jammer.

Chicago-style roller derby is known for being a highly physical and intense form of the sport, with players often using brute force and strategic maneuvers to gain an advantage on the track. It has a large and dedicated following in Chicago and throughout the United States, with many amateur and professional leagues competing at local and national levels.
