General Rules of Slamball

  • Both teams can field 4 players at a time and make unlimited substitutions.
  • Just like basketball, teams have to send the ball through the opposition’s net to score a goal and save their own nets simultaneously.
  • For every goal scored, the scoring team gets 2 points.
  • For every slam dunk or a throw outside of the three point arc (marked on trampoline), the team gets 3 points.
  • On the trampoline, there is a jumping area. An opposition team member can’t stay in this jumping area for more than 3 seconds. If he fails to leave this before on time, the other team is awarded possession of the ball.
  • Once the referee has thrown the ball in the air to start the game, the first to get possession of the ball gets 15 seconds to score the goal. Failing to do so would result in the other team getting possession of the ball.
  • The opposition can get the ball from you by either blocking shots, rebounding the miss shot or by stealing from your hands.
  • Unlike basketball, where you have to keep dribbling or passing the ball to your partner, you can pass the ball to yourself by hitting any of the barriers in the court. This is perfectly legal in slamball.

Playing Roles & Positions

Each team can field 4 players at a time, and these 4 players play in the following positions:

Handler: A handler’s primary job is to control flow of the game by running to the opponent’s net along with the possession of the ball. He assists the gunners to attack the basket alongside blocking any shot coming towards his half.

Gunner: A gunner is like a striker. His job is to attack the opponent’s basket and score as many goals as he can.

Stopper: Although there are no restrictions in the game, any player can play at or move to any position, a stopper is like a goalkeeper. He blocks the goal-scoring attempts from the offensive side by using himself as a shield.

What is a Slam Dunk?

Common Fouls in Slamball

Here are some of the common fouls that occur in slamball and their punishments:

  • If a player checks in the back of his opponent, who is in possession of the ball, his team faces a faceoff. A faceoff in slamball is like a penalty in which one player from the non-offensive side attempts to throw the ball in the net while one player from the opposite side protects the net.
  • If a player with the possession of the ball is attempting to enter the trampoline and to prevent him from doing so, his opponent checks him, this would result as a faceoff for the offensive team.
  • When two players from the offensive side bounce or step on the same trampoline, it results in a turnover. Turn over means giving possession of the ball to the other side.
  • Abusing or arguing with a referee also results in a faceoff for the offensive side.
  • Staying in the jumping trampoline area for more than 3 seconds results in a turnover.
  • If a player makes 3 fouls in a single match, he is disqualified from the game.
  • If a defending player intentionally disrupts the bounce of the offensive player, this is called Popcorn and is a foul. Referees can award face off or turn over to the non-offensive side in case of Popcorn.
