NOW TRY THE HARD ONE! HAHAHAHAHAHA!

Then do this
River crossing problem

(Remember, the boat doesn't have to return empty.)


Try this one (the answer and more are here. Use coins or something to simulate the camels)

Four tasmanian camels traveling on a very narrow ledge encounter four tasmanian camels coming the other way.

Tasmanian camels never go backwards, especially when on a precarious ledge. The camels (being somewhat marsupial in nature) can jump over each other, but only if there is a camel sized space on the other side.

The camels didn't see each other until there was only exactly one camel's width between the two groups.

How can all camels pass, allowing both groups to go on their way, without any camel reversing?
