WHAT MAKES IT DIFFERENT

The AI is not a toy.

Chess runs Stockfish 18, Xiangqi runs Pikafish, Othello runs Egaroucid, Gomoku runs Rapfi

and Go runs GNU Go — across 10 difficulty levels, so the lower rungs are still beatable.

No install, no account.

Optional Google sign-in exists only if you want rankings and saves that follow you across devices.

Works offline.

It's a PWA — single-player games keep running with no connection at all.

Seven languages.
