The game is played with two teams of nine, one of whom, rides in a shopping cart who is the only one who can score a point for their team, but who has no means of locomotion on their own.
Typically, the shopping cart rider is armed with whatever handy item the venue affords: parts of mannequins, small electric kitchen appliances, and glassware are commonly employed in the Department Store venue for their piecewise flexibility, ball-and-chain momentum, and explosive shrapnel qualities respectively.
Mops, gallon jugs of milk, and twelve-pack cans of soda are favorites of the supermarket circuit (reach, dual-wielded clubs or heavy projectiles, and hard-hitting single projectiles)
Recently school gymnasiums have entered into the list of accepted locations. The lack of available weaponry for the shopping cart rider has lead to the expansion of rules regarding the number of team members, increasing the store limit from nine to twenty.
Gameplay parallels many rules and tactics seen in traditional roller derby, but with the destabilization provided by the slippery linoleum, tile, and hardwood flooring against the smooth tube socks, there is an increased propensity for players sliding, colliding, and falling down.
