"Backyard Basketball" offers two primary modes of gameplay: Single Game, which allows the player to select a team to compete against a computer-controlled team, and Season Play, which allows the player to select a team to compete against a series of computer-controlled teams over an 18-game season, including two best-of-three playoff series and a best-of-five championship series should the player achieve a large number of victories. The Single Game mode also allows the player to compete against a second player or to practice using a single character.
