Nim

Nim is a game in which players take turns removing objects from heaps, but may only take from one heap at a time. In the normal version, the player to take the last object wins; in misere, the player to take the last object loses. The name and the complete theory of the game were invented by [C. L. Bouton]? of Harvard University about 100 years ago.
