NBA Street is a basketball video game of three-on-three street basketball. Aside from the basic structure of basketball, players try to collect trick points, which are scored through the use of almost every basketball game maneuver such as faking out defenders, shot blocking, diving for the ball, and dunking. If a team fills a special meter through flashy and effective gameplay, they get to perform a Gamebreaker, which is a special shot that not only adds to their score, but it subtracts an amount from their opponents' score.
Single player options included a user-created player touring famous American locations, picking up teammates from NBA rosters along the way.
The gameplay could be considered an "arcade" style of basketball in that it is not a true simulation, similar to the NBA Jam series. For instance, in-game players are able to jump high enough to grab three-point shots mid-arc (goaltending is permitted and is often used as a defensive strategy). Games are scored not by traditional standards, as two-point field goals are worth one point, while made shots behind the 3-point line are worth two. Instead of a time limit, the first team to score 21 points are deemed the winner. However, the winner must win by 2.
