In the year 1981, young people called children would while away the tedium of living in 1981 by daring each other to run out in front of heavy traffic. It was a global phenomenon. Hundreds of bored feral kids were mown down by articulated lorries and racing cars during the infamous highway massacres of late '81.

At the same time in a bizarre coincidence, Japanese company Konami created a video game called Frogger, its basic principle similarly based on roadkill, but this time a frog was dodging the vehicles instead of a small child.

Your goal is to safely guide five frogs across the road and river so that they each in turn reach their lily pad homes. There are many obstacles along the way: if you're not too careful you could be flattened by a car, drowned in the river or eaten by a crocodile. So take it easy on the little froggies.
