Unlimited subs are allowed during play. Play games to 3 or 5. Each team has four players. After a player catches a goal, they touch the disc to the ground and start again, attacking the opposite goal. Each team has two substitutes.
Substitution can happen at any time by tagging the player on the sideline.
A game is usually played for 15 minutes. The court is two 10m x 10m boxes separated by a 5m wide no-man's land. The court can be outdoor or indoor. A pair of players stand in each box, each pair with one disc. Each team serves simultaneously and aim to land the disc in the other team's court.
