The Wolf , the Goat , and the Cabbage 


The Classic Problem:

A man once had to travel with a wolf, a goat and a cabbage. He had to take good care of them, since the wolf would like to taste a.piece of goat if he would get the chance, while the goat appeared to long for a tasty cabbage. After some traveling, he suddenly stood before a river. This river could only be crossed using the small boat laying nearby at a shore. The boat was only good enough to take himself and one of his loads across the river. The other two subjects/objects he had to leave on their own. How must the man row across the river back and forth, to take himself as well as his luggage safe to the other side of the river, without having one eating another?


An Interactive Version:

Click on the cabbage, the goat or the wolf to place them on the boat or on the bank. Click on the arrow to make the boat cross the river. The man's name is Lulu.

There is a second level option in this interactive version. It entails two additional pieces of luggage - a stick and fire! In addition to the  restrictions of Level 1, if the stick and the wolf are left on their own, the stick will beat the wolf! If the fire and the stick are left on their own, the fire will burn the stick!
