Impartial Game

A Game in which the possible moves are the same for each player in any position. All positions in all impartialGames form an additive Abelian Group. For impartial games in which the last player wins (normalform games), the nim-value of the sum of two Games is the nim-sum of their nim-values. If the last playerloses, the Game is said to be in misère form and the analysis is much more difficult.
