निम रणनीति का एक सरल गणितीय खेल है.

Nim is a simple mathematical game of strategy. Two players take turns removing objects from distinct heaps or rows. In our game Nim Toornament we have a board with four rows containing seven, five, three and one field. At start of the game fields are occupied with 16 tokens. On each turn, a player must remove at least one token, and may remove any number of tokens provided they all come from the same row. The player who takes last token loses the game.
