NBA Jam (ＮＢＡ ジャム) is the first in a series of basketball games which carry the NBA license. Unlike the later NBA Live or NBA 2K series, the NBA Jam series is known for being more "arcade-style," with faster gameplay, fewer players on screen, and highly exaggerated dunks. The first game was released in 1993 in arcades and then ported to (among other consoles) the Sega Mega Drive, Sega Game Gear and Sega Mega-CD. A Sega Master System version was also planned at one stage but was canceled.

Later, a sequel named NBA Jam Tournament Edition was released on Sega consoles.

Gameplay

The game puts two players per team on the basketball court. Each game consists of four quarters of three minutes each. The goal is to outscore the other team; baskets from within the three-point line are worth two points, and shots from outside of it are worth three points. A key feature of the game 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 a 24-second shot clock. This means that the player is able to freely shove or elbow opponents out of the way.

Players are moved around the court with the D-Pad. Players have a turbo meter that increases their running speed by holding . The turbo meter is depleted as it is used, but it quickly recharges when it is not used.

The 16-bit versions of the game support up to four players simultaneously with the Team Player, and the Game Gear version supports two players with a Gear-to-Gear Cable. In one- and two-player games, players control one member of their respective teams and have AI-controlled teammates. The game can automatically switch control to whichever team member has the ball by enabling Tag Mode in the options. Unlike later games it is not possible to swap players at halftime.

The game also has a Computer Assistance feature enabled by default that increases the precision of the losing team's shots to ensure a more competitive game.

	Tip-Off
	Each game starts with a tip-off, where a player from each team leaps with for possession of the ball. Possession of the ball goes to the home team (team two) at the beginning of the second and fourth quarters and to the visiting team (team one) at the beginning of the third quarter, regardless of who wins the tip-off or who had possession of the ball at the end of the last quarter.
	Defense
	When the player's team does not have possession of the ball, the player can try to block the opposing team's shots with . If the player has turbo, the player can perform a higher "super block" with +. If the ball is on the downward trajectory of its arc when it is blocked, the player is charged with goaltending and the other team receives points for a successful basket. However, if the ball touches the rim of the basket, any player on either team can grab it. When near an opposing player, the player can try to steal the ball with . The ball flashes white when the other team touches it. If the player has turbo, the player can also shove another player with +. Shoving can cause the other player to drop the ball or move another player out of the way to clear a shot for a teammate.
	Offense
	When the player's team has possession of the ball, the player can perform a jump shot by holding . The ball is released when the button is released; releasing the button at the apex of the leap leads to a more accurate shot but increases the risk of a defender blocking or stealing the ball. The player can perform a jump pass by pressing while in the air. The player can fake out the other team by tapping , but since this discontinues the player's dribble, the player can no longer move with the ball and must pass or shoot. The player can perform a lay-up or a dunk by pressing while running near the basket with turbo. There are a number of different jams that are performed depending on the player's speed and positioning. If a player makes three baskets in a row, the player becomes "on fire" and has unlimited turbo, no goaltending, and increased shooting precision. The "on fire" mode continues until the other team scores or until the player who is "on fire" scores four additional consecutive baskets while "on fire." The player can pass the ball with . When playing with an AI teammate, pressing forces the AI to pass the ball. Opponents can intercept the ball as it is being passed. If the player has turbo, the player can do a "super pass" with + that is harder to intercept. The player can protect the ball by tapping , which can prevent opponents from trying to steal it.
