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. The player uses the 4-direction joystick to hop the frog once. Losing all frogs is game over. The 1982 Atari 2600 version from Parker Brothers sold 4 million cartridges, making it one of the best selling Atari 2600 games.
