Game play consists of a series of short matchups ("jams") in which both teams designate a scoring player (the "jammer") who scores points by lapping members of the opposing team. The teams attempt to assist their own jammer while hindering the opposing jammer —in effect playing both offense and defense simultaneously. Roller derby is played by more than 1,000 amateur leagues on every inhabited continent.

Game play

Contemporary roller derby has a basic set of rules, with variations reflecting the interests of a governing body's member leagues. The summary below is based on a comprehensive rule set developed by the Women's Flat Track Derby Association (WFTDA), which is used by the vast majority of leagues. In March 2010, Derby News Network

 are required to play by WFTDA rules, while members of the Canadian Women's Roller Derby Association are encouraged to join the WFTDA.

Basics of play

Roller derby is played by two teams of five members simultaneously skating counterclockwise on a circuit track. Each team designates a scoring player (the "jammer"); the other four members are "blockers." One blocker is designated as a "pivot"—a blocker allowed to become a jammer in the course of play. The jammer wears a helmet cover bearing two stars; the pivot wears a striped cover; the remaining members' helmets are uncovered.

The bout is played in two periods of 30 minutes. Point scoring occurs during "jams": plays that last up to two minutes. During a jam, points are scored when a jammer in scoring position laps members of an opposing team. Each team's blockers use body contact, changing positions, and other tactics to assist its jammer to score while hindering the opposing team's jammer. Certain types of blocks and other play are violations; referees call penalties and require violators to spend time in a penalty box.

Jams

Play begins by blockers lining up on the track's starting line (the "pivot line"). The jammers start from a second starting line 30 feet behind. With a starting whistle, the blockers begin to skate; when the last blocker crosses the pivot line, a second whistle signals the jammers to start.

The skating blockers form a "pack": while blockers must maintain the pack by remaining within ten feet of the next-nearest blocker, they may move freely and skate anywhere on the track. The first jammer to legally pass all opposing blockers wins the status of lead jammer for the remainder of the jam. Subsequent to her first pass through the pack, the jammer scores a point every time she laps an opposing team member.

The lead jammer can stop the jam at any time by signaling to the referees by placing her hands on her hips. If the jam is not stopped early, it ends after 2 minutes. Teams then have 30 seconds to form up for the next jam. Team members typically rotate between jams from the 14 players on the team's roster. Designations may change between jams: a pivot in one jam might be the jammer in a later jam.

Positions

Position Helmet Cover Responsibility References
Jammer Stars Scores points by lapping opposing team members
Blocker None Assist the team's jammer to progress through the pack. Hinder the opposing jammer by preventing her from passing.
Pivot Stripes A blocker who may be designated as a jammer during the course of a jam. Establishes team strategy during play.

Scoring

The jammer scores by passing opposition team members. Each jammer must first complete a pass of all the opposing team's blockers. After this initial pass through the pack, the jammer scores a point each time she passes an opposing team member, including the other team's jammer. For example the jammer for team A may pass 5 blockers during a jam, the jammer for team B passes 3. When the jam ends—either because the 2-minute limit is reached, or because the lead jammer has "called the jam" beforehand—the score would be 5 points for team A, 3 for team B.

Blocking

Roller derby skaters attempt to knock opponents out of bounds or impede their movements by blocking. Legal blocks follow certain rules. Contact by hands, elbows, head and feet are prohibited, as is contact above the shoulders or below mid-thigh. Contact may not be from the rear, only from a player's front or sides.

Penalties

Referees determine rule violations. Each type of violation carries major or minor penalties, or no penalty at all. A player receiving a major penalty, or four minor penalties, is removed from play to sit in a penalty box for one minute. If a jam ends beforehand, the player remains in the penalty box during the subsequent jam until the minute penalty is completed. A player with seven major penalties is ejected from the game.

Equipment

Players skate on four-wheeled ("quad") roller skates, and are required to wear protective equipment, including a helmet, wrist guards, elbow pads, knee pads, and mouth guards.

Strategy

Roller derby is exceptional in that it is a game where offense and defense are played simultaneously. This adds complexity to game play strategy: for example, blockers may create a large hole for their jammer to pass through and score, but this same maneuver might also allow the opposing team's jammer to score.
  • Ending the Jam The lead jammer can end the jam at any time, thus she controls the opposing team's ability to score points. Ideally the lead jammer will attempt to score as many points as possible, and end the jam before the opposing team scores any.
  • Passing the Star The jammer for a team may "pass the star" to the pivot — that is, she hands the star helmet cover to the pivot, at which point the pivot becomes the scoring jammer for the team. A jammer might pass the star because of fatigue, injury, penalty trouble, or because the pivot is in a better position to score.
  • "The Whip" A blocker or pivot grasps her jammer's hand and swings her forward transferring speed and momentum to the jammer.

  • "Walling Up" A basic "wall" consists of two blockers working together to take up as much space on the track as possible to make it difficult for the opposing team to maneuver. "Walling up" refers to creating a wall formation at a strategic time, so the opposing team (especially the jammer) has no time to respond. A wall can inhibit, slow down, and ultimately trap the opposing jammer, and may last an entire jam if they can effectively hold the opposing team. Variations on the strategy include setting up blockers to rotate through the wall positions.
  • "Getting the Goat" The pack is defined as the largest group of in bounds Blockers, skating in proximity, containing members from both teams. In the "goatherding" strategy, one team surrounds the slowest blocker of the opposing team, and then slows more so that that group becomes the pack. The opposing team, skating ahead, are thus put out of play and thus cannot legally block the goatherders' jammer.
  • "The Diamond" In a similar strategy, four blockers form a diamond around the opposing jammer to prevent her from getting through the pack.
  • Slow Start When a team's jammer is in the penalty box at the start of a jam, they may attempt a slow start: the other team's jammer can't enter the jam until the last blocker passes the pivot line. A slow start prevents the entry of the other team's jammer.
  • Intentional Minor Penalties A skater with 4 minor penalties will be sent to the penalty box for a minute. It is easy for a jammer with three minor penalties to incur a fourth penalty, thus taking her out of play and leaving her team unable to score. Some teams will therefore send a potential jammer with 3 minor penalties into the game as a blocker, with the intent that player intentionally incurs a fourth minor penalty in a less critical blocking role — for example by intentionally entering the starting line-up behind the jammer line instead of the pivot line.
  • Other Strategies A newly developed "Western Style" strategy has been developed in which a blocker who bumps the opposing jammer off the track skates backwards, forcing the jammer to re-enter further behind the pack.

By 1939, after experimenting with different team and scoring arrangements, Seltzer's created a touring company of four pairs of teams (always billed as the local "home" team versus either New York or Chicago), with two five-person teams on the track at once, scoring points when its members lapped opponents.

 ethic is prominent. Members of fledgling leagues often practice and strategize together, regardless of team affiliation, between bouts. Most compete on flat tracks, though several leagues skate on banked tracks, with more in the planning stages.

Each league typically features local teams in public bouts; these are popular with a diverse fan base; larger venues hosting audiences ranging from 4,000 to 7,000 are no longer unusual. Many leagues took advantage of the release of the roller derby movie Whip It to increase awareness of the sport.

Although the early 2000s revival of roller derby was initially all-female, some leagues later introduced all-male teams and co-ed games. Furthermore, as of February 2010 there were over 40 junior roller derby programs across four countries in various stages of development. Despite being viewed by some as risqué adult-oriented entertainment, the positive empowering aspects of the sport are a draw for some youth.
