3x3 basketball competitions in the United States

Big3 (stylized BIG3) is a 3-on-3 basketball league founded by the hip-hop musician and actor Ice Cube and entertainment executive Jeff Kwatinetz. The league consists of 12 teams whose rosters include both former NBA players and international players. The rules of Big3 games contain deviations from the official rules of 3-on-3 basketball as administered by FIBA. It debuted in 2017 and takes place during the NBA offseason. In January 2020, Big3 announced its rule set would be the core of a new basketball variant called "Fireball3" (stylized FIREBALL3).
