Nim is one of the oldest strategy games in the world. Nimix is the misère version, played on the beach with birds:
- The birds are stacked in four rows of 1, 3, 5 and 7.
- On your turn, click birds to remove any number you like — but all from a single row.
- Press End turn and the surfing computer answers.
- Whoever is forced to take the very last bird loses. 🪶
Strategy tip: the secret is the nim-sum — the XOR of the row sizes. Perfect play keeps handing your opponent a nim-sum of zero. The AI on "Perfect" knows it, so try "Easy" first!
