Streetball

As such, its format is more conducive to allowing players to publicly showcase their own individual skills.

Many cities also host their own weekend-long streetball tournaments, with Hoop-It-Up and the Houston Rockets' Blacktop Battle being two of the most popular.

[3] Since the mid-2000s, streetball has seen an increase in media exposure through television shows such as ESPN's Street Basketball and City Slam, as well as traveling exhibitions such as the AND1 Mixtape Tour, YPA, and Ball4Real.

[5] The etiquette of what rightly constitutes a foul, as well as the permissible amount of protestation against such a call, are the products of individual groups, and of the seriousness of a particular game.

Special rules have been developed for half-court play: A common feature of street basketball is the pick up game.

Special rules have been developed for one-on-one play: A popular variation of street basketball is 21, also known as Hustle, American, St. Mary's, V or Varsity, Roughhouse, 33, 50 or Crunch, or "New York."

For this reason, it is exceedingly difficult to "drive to the hole" and make lay-ups in "21."

Therefore, and also because of the emphasis on free-throws, "21" is very much a shooter's game, and because a successful shot means you keep the ball, it is possible for there to be come-backs when a player recovers from a large deficit by not missing any shots (this can also result in failure when they miss their final free-throw at 20 points and revert to 13 or 15).

"21" is popular because it allows an odd number of people to play, unlike regular basketball or other variants.

If a player fails to duplicate the shot, they acquire a letter, starting with H and moving rightward through the word "Horse".
