Rules

An introduction to the basic rules of 3x3 basketball and the competition format of "3x3UNITED," the league MIE SHINOBI GATHERS competes in.

WHAT IS 3x3

What is 3x3

3x3 is a three-a-side (plus one substitute) form of basketball played on a half court. FIBA, the International Basketball Federation, formalized its rules in 2007, and it became an official Olympic event starting at the 2021 Tokyo Olympics. Compared to traditional 5-on-5 basketball, its compact court and short game length make for fast, dynamic play.
