3v3 Basketball Rules: The Definitive FIBA Guide [2026]

Court Setup and Team Rosters

Whether you are transitioning from full-court games to the asphalt or preparing for an official FIBA tournament, mastering the official 3v3 basketball rules is crucial. This high-speed variation is played on a compact half-court game setup using a single hoop.

To field a team under official guidelines, you must strictly follow these roster requirements:

Roster Size: Each team must consist of exactly 4 players (3 players on the court and 1 substitute).
Game Start: All 3 active players must be physically present on the court for the game to officially begin.
Court Dimensions: The playing area is a standard FIBA half-court measuring 15 meters wide by 11 meters long.

Unlike traditional basketball, there is no jump ball to start the match. Instead, a pre-game coin toss determines possession, allowing the winner to choose to take the ball at the start of the game or at the beginning of a potential overtime period.

Scoring and the 12-Second Shot Clock

The fast-paced nature of 3v3 basketball is driven by simplified scoring and a rapid possession cycle. There are no three-pointers here; instead, the court features a two-point line (the traditional three-point arc).

Here is how points are tallied under official FIBA 3x3 rules:

1 Point: Awarded for every successful shot made from inside the arc.
2 Points: Awarded for every successful shot converted from behind the arc.
1 Point: Awarded for every successful free throw.

To prevent stalling and maintain an explosive pace of play, a strict 12-second shot clock is enforced. Teams must attempt a shot that hits the rim within this window, or possession is immediately turned over to the defense.

Game Clock and Overtime Rules

A standard 3v3 basketball game is designed to be short, intense, and highly engaging for spectators. The official game length is 10 minutes of stop-clock play, meaning the clock stops during all dead-ball situations and free throws.

However, the game can end early through a "sudden death" rule. The first team to reach 21 points or more before the 10-minute limit expires wins the game immediately.

If the score is tied at the end of regulation, the game enters overtime. Under official overtime rules, a brief 1-minute interval is given, and the first team to score 2 points in overtime is declared the winner.

Fouls, Penalties, and Free Throws

With only three players on each side, court space is tight, making physical play common. However, the penalties for fouling accumulate rapidly. Individual player fouls are tracked, but players are not disqualified based on personal foul counts; instead, the focus is on the team fouls penalty.

Fouls 1 through 6: Non-shooting fouls result in a simple check-ball. Shooting fouls inside the arc award 1 free throw, while shooting fouls behind the arc award 2 free throws.
Fouls 7, 8, and 9: These automatically award 2 free throws to the opposing team, regardless of whether it was a shooting foul.
Foul 10 and subsequent: These award 2 free throws plus ball possession to the opposing team.
Technical & Unsportsmanlike Fouls: Technical fouls award 1 free throw and ball possession. Unsportsmanlike fouls award 2 free throws and ball possession.

Possession Clearance and Live-Ball Play

How the ball changes hands is one of the most unique aspects of the game. There are no breaks to take the ball out-of-bounds after a made basket or defensive stop.

To maintain legal play, teams must execute a proper possession clearance:

After a Made Basket: The non-scoring team starts play directly under the basket. They must dribble or pass the ball behind the arc before they can attempt a shot.
After a Steal or Block: If the defensive team secures the ball inside the arc, they must clear it by establishing both feet completely behind the two-point arc.
Held Ball Situations: In the event of a jump ball or tied possession, the ball is automatically awarded to the defensive team.
Stalling: Actively refusing to play or failing to attempt a shot is a violation and results in a turnover.

Each team is allowed exactly one 30-second timeout per game, which can be called by any teammate during a dead-ball situation.

Understanding these 3v3 basketball rules reveals why this fast-paced format has taken the global sports world by storm. Officially added to the Olympic Program in 2017, this structured half-court game lowers the barrier to entry while demanding peak conditioning and sharp tactical execution.
