Commonly Used Roller Derby Terms
1. Jammer — The Skater Who Scores the Points
If you see a skater with a star on their helmet, that’s the jammer. Their job is simple to explain but tough to execute: score points by passing opposing blockers. Every time the jammer loops back through the pack on a scoring pass, the scoreboard can jump quickly. They are the ones to watch if you want to understand the flow of the game.
2. Blocker — The Defensive (and Offensive) Engine of the Team
This is one of the most commonly used roller derby terms. Each team has four blockers on the track, and they’re responsible for almost everything that happens in the pack. They slow the opposing jammer, open lanes for their own jammer, and create formations that shift the pace of a jam. When you see a wall suddenly close or a gap quickly open, that’s the blockers at work.
3. Pivot — The Skater With the Stripe on Their Helmet
The pivot is a special type of blocker identified by the stripe on their helmet. They can become the jammer if the star is passed to them—a move called a star pass. Pivots often direct the pack, communicate strategy, and help stabilize the team’s shape when the jam gets chaotic.
4. Pack — The Center of the Action
The pack is the group of blockers from both teams skating closest together. It’s the heartbeat of every jam. The speed and position of the pack determine penalties, legal actions, and how both jammers navigate through traffic. If you want to understand why a penalty was called or why one jammer flew through easily, look at the pack.
5. Lead Jammer — The Skater Who Controls the Clock
The first jammer to break through the pack legally becomes the lead jammer. This role is powerful because the lead jammer can end the jam early by tapping their hips. Calling off the jam prevents the opposing jammer from scoring and helps teams control momentum.
6. Apex Jump — The Most Crowd-Pleasing Move in Derby
An apex jump is when a jammer leaps over the inside curve of the track to bypass blockers. It’s fast, daring, and often results in a burst of cheers from the crowd. This move requires timing, balance, and confidence—one of the reasons it’s a fan favorite.
7. Cut Track — A Common Penalty That Sends Jammers Back
A cut track happens when a jammer (or blocker) leaves the track, re-enters, and ends up in front of someone they were behind. Even if the advantage seems small, it’s still illegal. The penalty sends the skater to the penalty box for 30 seconds, giving the opposing team a huge scoring opportunity.
8. Recycle — Sending the Jammer Far Behind the Pack
Recycling is one of the most important defensive moves in roller derby. When blockers push a jammer off the track and then move backward, the jammer must re-enter behind them. This forces the jammer to redo part of the pass and gives the blockers more time to control the jam.
9. Wall — The Formation That Stops a Jammer in Their Tracks
A wall is when blockers skate together in a tight formation to stop the opposing jammer. Depending on the situation, you’ll see two-wall, three-wall, or four-wall structures. These formations shift quickly, making it hard for the jammer to find a clear lane.
10. Star Pass — A Mid-Jam Strategy Switch
Sometimes the jammer gets trapped and needs help. That’s when the star pass comes in. The jammer hands the star helmet cover to the pivot, instantly making the pivot the new jammer. It’s a fast, strategic move that can change the momentum of a jam.
