"Just like the real volleyball, Rebound is a game of skill designed for two players, with each player represented on the screen by a horizontal bar. The objective is to hit the ball over the electronic net and overt the net... back and forth, faster and faster until one opponent misses and a point is scored. With pratice, a player can even angle the degree of return. And, just like real volleyball, each player has three chances to return the ball on each volley. The action is highlighted by an audio 'Bleep' each time the ball is hit, adding to the overall action and excitement."
Rebound was Atari’s fourth coin-op game and was a simple version of volleyball that required two-players. Steve Jobs signed off on the wiring diagram for the cabinet. A schematic dated 11/31/73 describes this game as “Volleyball”. The game was like a vertical version of pong in which hitting the ball would send it on a parabolic path over four short lines that represented a net. The hardware featured a discreet logic design.
Spike was exactly the same game as Rebound, but released by Kee Games a month later.
