Play the classic math strategy game Nim against a mathematically perfect computer opponent, or a friend on the same device. Free and instant.
Your turn
Normal play rule: whoever takes the last object wins. The CPU plays a mathematically optimal strategy using the Nim-sum (XOR) of the piles - it never loses if it is ever handed a nim-sum of zero. Scores are saved in this browser only.
À propos et fonctionnement
Discover how Nim executes your workflow locally in your browser with zero server uploads and total privacy.
Nim on Neranjan Tools is an ultra-fast, client-side utility crafted to deliver professional-grade processing without the privacy risks or upload delays of traditional cloud services. Whether handling sensitive business contracts, personal photos, or code snippets, you can accomplish your task in seconds.
Unlike conventional web converters that upload your confidential files to remote third-party servers, this tool operates 100% inside your browser's local sandbox using HTML5 Canvas, WebAssembly, and modern JavaScript engines. Your files are loaded into your device's memory, processed instantly by your local CPU and GPU, and saved directly to your disk, ensuring zero data leaks, zero server logging, and immunity to malware execution.
