An ancient mathematical game where two players take turns removing objects from piles, trying to force the opponent into a losing position.
The origin is uncertain; it may come from German 'nimm' (take), or possibly from an Asian game. The name became standard in English in the early 1900s for this mathematical game.
Nim is the first game that computers proved they could play perfectly—mathematicians proved there's a winning strategy that never fails, making it the first 'solved' game. Yet humans still enjoy playing it, which shows games aren't just about winning but about the thinking involved.
