What is 3x3 basketball?

Both teams attack the same basket. After a made basket, possession immediately passes to the other team, which resumes play from underneath the basket. After a defensive rebound, a steal or a block, the defensive team must take the ball behind the arc before it can attack.

This action is called clearing the ball. It prevents an attack from continuing directly under the basket after a change of possession.

When play stops and the ball returns to play, the offence most often starts with a check-ball: a defensive player hands the ball to an offensive player at the top of the court. A detailed explanation of the check-ball, clearing and restarting play is available in the guide 3x3 basketball rules.

In 3x3, there is no other half of the court for a team to retreat to. After every change of possession, play continues in the same space, and an offence lasts 12 seconds. Defence, taking the ball behind the arc and making a new attacking decision therefore follow one another in a short period of time.

Players need to recognise the situation quickly: whether to finish the action themselves after a turnover, play two-on-two, create an open shot or find an unmarked teammate. On defence, switching, defending two-on-two actions and quickly closing space around the basket are common.

A basket scored inside the arc is worth one point, while a basket scored from behind the arc is worth two. Each made free throw is worth one point.

A game lasts a maximum of ten minutes of playing time, but ends earlier if a team reaches 21 points. If the score is tied at the end of regulation, overtime is played, and the first team to score two points wins.

This format makes every decision important, especially late in a game. A complete explanation of scoring, game length, personal and team fouls is available in the guide 3x3 basketball rules.

3x3 is played in men’s and women’s competition, in senior and younger age categories, and in club, open and national-team events. It can be a first introduction to basketball, an addition to 5-on-5 or an independent competitive pathway.

For official FIBA events, players have their own FIBA 3x3 profile. Results from recognised tournaments count towards the individual ranking, which is an important part of the international system for players and teams.

Local and national tournaments create opportunities for regular competition, while some can open a route to international events. In the men’s club system, Lite Quest, Quest, Challenger and World Tour Masters are important formats, while the women’s elite has a separate system through the FIBA 3x3 Women’s Series. National-team competitions include the Nations League, continental championships, the World Cup and the Olympic Games.

How these formats connect is explained in the guide FIBA 3x3 Pro Circuit, Women’s Series and National Teams. For the domestic scene, Croatian tournaments and Zagreb’s place within that system, read 3x3 basketball in Croatia and Zagreb.
