What is Indoor Street Basketball?

Traditionally played outdoors, StreetBall or 3 on 3 is a variation of the full game with modifications to the rules. Played in both half court and full court styles from 3 to 4 players per team. StreetBall is much faster than the traditional version and offers social teams a great way to enjoy the sport. Sign up your team now.

Rules of Indoor StreetBall are similar to the traditional version of Basketball, but for those who have never played, the basics are:

3 on 3 (Half Court) basic rules

  • Each team consists of three players minimum. (substitutes available)
  • The game is played on a half-court, with one basket.
  • A jump ball is not used to start the game. Instead, a coin toss is held immediately before the game.
  • There are no jump balls at any time in the game; neither is there an alternating possession rule. In any held ball situation, the defensive team is granted possession.
  • Every successful shot inside the arc is awarded one point, while every successful shot behind the arc is awarded two points.
  • The game consists of 3 periods of 10 minutes. Each period is scored separately. In the event of a tie after 10 minutes, play continues with golden point. A team must win two of the three periods to win the match.
  • Game play starts with the defensive team exchanging the ball with the offensive team behind the arc. This exchange is also used to restart the game from any dead ball situation. If a foul is committed that results in the non-fouling team retaining possession — i.e., a technical or "unsportsmanlike" foul - the non-fouling team will receive the exchange.
  • If the defense gains possession of the ball within the arc, by a steal, a block or a rebound, the team must move the ball behind the arc before being allowed to take a shot.
  • After a made goal or free throw (except for technical or unsportsmanlike fouls and team fouls 10 or more), play restarts with a player from the non-scoring team taking the ball directly under the basket and then dribbling or passing it to a point behind the arc. The defense is not allowed to play for the ball inside the block/charge semi-circle under the basket.
  • In 3x3, a substitute becomes official once the player leaving the game has made physical contact with the substitute. Unlike the full-court game, no action from referees is required. Substitutions can only occur during dead ball situations.
  • There are no Time Outs during the periods.
  • Individual personal foul counts are not kept. In other words, players cannot be disqualified on the basis of personal fouls. However, a player who commits two unsportsmanlike fouls is disqualified and asked to leave the court.
  • Fouls during the act of shooting inside the arc are awarded 1 free throw, whilst fouls during the act of shooting behind the arc are awarded 2 free throws. However, team fouls 7, 8 and 9 are awarded two free throws, whilst team fouls 10 or more are awarded two free throws and possession of the ball.
  • Technical fouls (including unsportsmanlike fouls) result in two free throws plus possession of the ball.

4 on 4 (Full Court) basic rules

  • 4 on 4 rules are essentially the same as 3 on 3 but is played within a full court (modified size)
  • Unlike 3 on 3 play starts from behind the baseline after points are scored.(same as traditional game)
  • Out of bounds results in handover and plays from the position the ball leaves the court. Out of bounds behind the baseline results in play starting from the side line position.
  • The scoring and foul system is the same as 3 on 3
  • The game consists of 3 periods of 10 minutes. Each period is scored separately. In the event of a tie after 10 minutes, play continues with golden point. A team must win two of the three periods to win the match.
  • There are no jump balls within 4 on 4 and play starts with a coin toss with the winning team starting from their baseline. All held ball situations result in a handover to the defensive team.
