Nim game: Nim is a simple combinatory game with finite possibilities. But unlike tic-tac-toe, that other game of limited possibilities, there is tremendous variety in both Nim's conception and implementation. The theory of the Nim game was discovered by mathematics professor Charles Bouton at Harvard University in 1901. In fact, Bouton, who wanted to use the game to demonstrate the advantage of the binary number system, found a simple formula, with which, from the state of play, players can determine correct moves immediately.
