The puzzle is to get the two tyres (two thin wooden rings) together on the same loop of rope. And then you have to get them back to the separate loops again. This one will really sort out the good drivers from the bad!
Crazy Car rope puzzle is a version of the African Ball puzzles which are the most common of all the ring-string-rope puzzles first played there. The jungle tribes of the Ivory Coast once used them in magic rituals and they are still amusing people today.
Later on the puzzles were played in Europe (documented in print as early as 1735). More modern versions called the Block and Tackle and Send You Loopy are pretty well known but this one has an extra ring to get past before you can complete the puzzle.
