Video Olympics is a video game cartridge for Atari Inc. for the Atari 2600. It is one of the nine original launch titles for that system when it was released. The game is a port of Atari's popular Pong series.
The games are a collection of "bat and ball" style games, including several previously released by Atari as coin-ops in the early 1970s. The games are played using the 2600s paddle controllers, and are for one to four players (three or four players requires a second set of paddle controllers).
