Twenty-one (basketball) - Wikipedia
Twenty-one, also called cutthroat, hustle, tip-it, noyceball, roughhouse, scutter, rough, or rebound[1] is a popular variation of streetbasketball. The game is played with any number of players on a half court, but typically when not enough players are available to at least play three-on-three. Twenty-one is an individual game that does not utilize team play. In some settings, it is considered a brutal game, as fouling is legal and thus some games can become violent and full-contact. However, the game's basic rules can be enjoyed by anyone, as most games are non-violent.
