Frogger is a simple game where you have to reach the frog at his home safely without failure. Your goal is to reach five frogs, one by one, before times run out. A level is complete only when you have moved all five frogs at top of the screen. Start from bottom of the screen where half of the screen consists of busy highway with five lanes of speeding cars and trucks. After avoiding the traffic without failure, you have to cross rest of screen which contains rushing river full with obstacle like logs, turtles, snapping crocodiles, water snakes, and otters. The sound effect is pretty simple.
