The game is set in two main sections: the road and the river. The road is filled with moving cars and trucks, while the river water itself is deadly. Later levels introduce snakes hovering above the water's surface, adding an extra layer of danger. Frogger must use various obstacles such as logs, turtles (which appear briefly), and alligators to its advantage, jumping into open cells containing flies for bonus points. Once all holes have been filled, progress is made to the next, increasingly difficult level.
