Off the Wall is a tennis arcade game, that was released by Bally and Sente in 1984; it is the fourth of the original batch of eight games to run on their SAC-I hardware, and the players must use two 2-way joysticks to move two tennis players left and right, on their respective sides of the net, with a trackball (which is limited to a horizontal movement) for rotating their right (racket-holding) arms and hitting the ball. The amount of points both players have scored will be displayed above them, on their respective sides of the net - and, unlike in real tennis, the game will only award a single point for every time your opponent fails to return the ball. The game is over when one player has scored eleven points; if there is only one player present, it is also worth noting that the second player will be controlled by the CPU.
