Double Dunk is a basketball video game for the Atari 2600 that simulates a two-on-two, half-court basketball experience. Each team has two on-screen characters: a shorter “outside” player and a taller “inside” player. In single-player mode, the player controls the on-screen character closest to the ball, either on offense or defense. In two-player mode, players can either control opposing teams or team up against a computer-controlled opponent.
At the start of each possession, both the offense and defense choose from a variety of plays, such as the pick and roll on offense. The goal is to score points or regain possession by intercepting or stealing the ball from the opposing team.
Double Dunk offers several customizable options for gameplay. Games can be set to last for a specific time or until a team reaches a certain number of points. Three-point shots and a ten-second shot clock can be turned on or off. Additionally, players can choose to include foul detection and/or a three-second lane violation, providing a more realistic and engaging basketball experience.
