Pong, while not the first videogame, was the first coin-op
arcade game and the first mainstream videogame that was
available to almost everyone. The origins of Pong lie with an
abstract tennis game created with an old oscilloscope and some
vacuum tubes by Willy Higinbotham way back in 1958. What
eventually became "Pong" was a pretty simple game with simple
rules - hit the ball across the playing field and try your best
to hit it past your opponents paddle on the other side. Use your
mouse to guide your paddle up and down. Find more Flash games at
