You have to be in a group. The group makes a circle. The first player tells the person next to him something in his ear which can't be heard by the others. Then the next person says something that has to have something in common with the word that was said to him. After all the players say something, you see the first word and the last. It will allways be SO different.
example: tree, flower, beautiful, girl, boy, tree and boy are SO different.
