— The basics

What is Nim?

Nim is one of the oldest mathematical games still played. Several piles of objects sit on the table. Players take turns removing one or more objects from a single pile. The player who takes the last object wins (in the most common version). It looks like a simple counting game. It is actually one of the most studied games in combinatorial game theory.

The fascinating thing about Nim is that it has a mathematically perfect strategy. If you know the XOR rule — adding pile sizes in binary — you can always win from a winning position. New players play instinct. Experienced players play maths. Beating a Nim AI is the moment you graduate from one to the other.

Beginner tips for Nim

Learn the XOR rule. XOR the pile sizes in binary — if zero, the position is losing.
Aim to leave the opponent in an XOR-zero state on every turn.
In small games, memorise the losing positions: (1,1), (2,2), (3,3) etc. are all instant draws.
When in doubt, count. Nim rewards thinking time.
Play against the AI repeatedly to build pattern recognition.
