📖 About

Nim is one of the oldest mathematical games in history, dating back centuries! Multiple piles of stones sit before you—take any number from one pile each turn. In the standard version, the player who takes the last stone loses. Despite simple rules, Nim contains deep mathematical theory using binary XOR operations. Perfect information, no luck—pure strategic thinking!

🎯 Objectives

Force your opponent to take the last stone (or be the one to take it in misère version). Plan your moves to leave your opponent in losing positions. Master the mathematical theory for guaranteed wins against suboptimal play!

🎮 How to Play

Select a row, then choose how many stones to remove. You must take at least 1 stone. The player forced to take the last stone loses the game.
