Strangely addictive game that I remember playing on my old Amstrad PC back in the day when Windows and MS-DOS was still in its embryotic stages. You are the frog and your task is to make it across the road without being hit by traffic, and finally make it across the river by skilfully hitching a ride on the floating logs. Sounds simple enough, but it's the end pockets which are the hardest - and watch out for those pesky crocodiles!
