3x3 basketball

This is a formalised version of streetball, a form of basketball designed for an urban setting. So it involves one basket, very few rules, a lot of showy improvisation, and probably rap music in the background.  3x3 has one hoop, a half court and a few more rules than street ball, and is played at great speed.  There are four players in a team but only three on court at the same time. The sport was declared an official sport of the Sumer Tokyo Olympics for both men and women.
