Pong Doubles is the official sequel to Atari's original Pong arcade, made in 1973.
It plays the same as the original 1972 Pong, except each player controlls 2 paddles. The paddles move dependitly with eachother, meaning they will stay in the same direction vertically. If the ball hits the back paddle, it will go through the paddle closest to the net. But if the ball hits the front of the paddle in the front, it will bounce back.
