1.) Each team consists of three players and one or two substitutes.
2.) The game is played on a half-court, with one basket.
3.) A coin toss is held immediately before the game. The winning team can choose to take possession of the ball at the start of the game, or take the first possession of a potential overtime period.
4.) 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.
5.) Every successful shot inside the arc is awarded two points, while every successful shot behind the arc is awarded three points.
6.) The game is to 25 points. The winner is the first team to score 25 or the team with the highest score at the end of the 20 minutes. A tie in regulation leads to an untimed overtime period, which is won by the first team to score four points in overtime (29 points total). Note that if a game is tied at 24 at the end of regulation, reaching 25 does not end the game.
7.) 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 latter essentially the same as the "flagrant foul" of North American rule sets) — the non-fouling team will receive the exchange.
8.) 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.
9.) The only common feature between the substitution procedure in full-court and 3x3 is that it can occur only in a dead ball situation. In 3x3, a substitute can only enter from behind the end line opposite the basket, and the substitution becomes official once the player leaving the game has made physical contact with the substitute. Unlike the full-court game, no action from referees or table officials is required.
10.) Each team is allowed one timeout. (The officials may still stop the game in case of player injury or other dangerous situations, as in the standard FIBA rules.)
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.
11.) Fouls during the act of shooting inside the arc are awarded 2 free throw, whilst fouls during the act of shooting behind the arc are awarded 3 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.
12.) Technical fouls (including unsportsmanlike fouls) result in two free throws plus possession of the ball. (Receiving 5 or more Techs in a season may disqualify you from the league).
13.) No verbal abuse with Refs will be tolerated!
14.) 20 minute game. Clock does not stop unless timeout called or Ref stops clock for injury. 1 Timeout per team.
15.) 5 Fouls and you foul out of the game. After 6 fouls its a 1-1 Free throw . After 8 fouls its 2 Free throws.
