A game which is played by the following rules. Given one or more piles (nim-heaps), players alternate by taking all or some of the counters in a single heap. The player
taking the last counter or stack of counters is the winner. Nim-like games are also
called take-away games and disjunctive games. If optimal strategies are used, the
winner can be determined from any intermediate position by its associated nim-value.
The nim-heap illustrated above corresponds to the game
of Marienbad.
