You Will Need
- Quad roller skates
- Protective gear
- 10 to 28 players
- Additional protective gear (optional)
Have the proper equipment
Have the proper equipment. Players must wear quad roller skates; inline and other skates are not allowed. Mandatory protective gear includes wrist and mouth guards, elbow and knee pads, and helmets.
Divide players into two teams. Each team can have up to 14 players on its roster, but only five can be on the track at any one time: three blockers, one pivot, and one jammer. The blockers and the pivot form a skating pack whose job it is to prevent the other team's jammer from getting past them.
Have players line up on the track, facing counterclockwise, and form a pack: The pivots line up on the pivot line, the jammers line up behind them on the jammer line, and the remaining blockers line up between the pivots and the jammer line.
If you are a pivot or a blocker, begin skating when the referee blows their whistle. When the last player passes the pivot line, the referee whistles twice, and the jammers join in. Thus begins the two-minute countdown known as a "jam."
Begin to jam
If you are a jammer, try to pass the pack; after passing the first time, you'll earn one point each time you legally pass an opposing team's blocker or pivot. If you are a pivot or blocker, try to help your jammer pass the pack while trying to block your rivals' jammer. Stay within 20 feet of the pack; otherwise, you are not allowed to assist or block the jammers until you slow down or speed up to rejoin them. .
Be the lead jammer
Try to be the first jammer to pass the pack; if you do, you'll be the "lead jammer," and can end the jam before the two minutes are up to prevent the other team from scoring. Signal your intention by putting your hands on your hips repeatedly.
Don't get penalized
Don't get penalized: You may block the other team's jammer using any body part above your mid-thigh with the exception of your forearms, elbows, hands, and head. Players who break the rules can be sent to the penalty box for one minute.
Pass the star
After a lead jammer is established, they may pass the jammer position over to the pivot by handing them their helmet cover. Only the position of jammer -- not the status of lead jammer -- can be passed on.
Play for an hour
At the end of each jam, players re-form the pack and begin a new jam. Play for two 30-minute periods, or less commonly, for three 20-minute periods. Whichever team has the most points at the end of the hour wins.
