The object of the game is to direct five frogs to their homes by dodging traffic on a busy road, then crossing a river by jumping on floating logs and alligators. Frogger was positively received as one of the greatest video games ever made. It was followed by numerous clones and several home-only sequels in the Frogger series. The 1982 Atari 2600 version from Parker Brothers sold 4 million cartridges.
