NBA Jam is a basketball game based on the National Basketball Association (NBA). NBA Jam, which features two-on-two basketball, and is one of the first real playable basketball arcade games. A key feature of NBA Jam is the exaggerated nature of the play. Players can jump extremely high and make slam dunks that defy both human capabilities and the laws of physics. There are no fouls, free throws, or violations except goaltending and 24-second violations. Additionally, if a player makes three baskets in a row, the character becomes “on fire” and has an unlimited turbo and increased shooting precision.
