Nim is a game where two players take turns removing objects from different heaps or piles. On each turn, a player must remove at least one object, and may remove any number of objects as long as they all come from the same heap or pile. The goal of the game depends on the version being played; sometimes the aim is to avoid taking the last object, and other times it is to take the last object.
