Six ways to think
Every game here is one of pure information: no dice, no hidden cards, no luck. Just a board, a position, and whatever you can see in it.
The AI thinks in a background thread, so the page stays responsive even while the hardest level is searching.
Why this hub
Built to be played, not monetised into oblivion
The engine runs on your machine
Every search — minimax for the piece games, Monte-Carlo tree search for Go — executes in a Web Worker on your own device. Nothing about your game is sent anywhere, and there is no server to be down.
Four honest difficulty levels
Level 1 is a genuine beginner that will hang pieces. Level 4 thinks for several seconds and will punish a loose move. Pick the one that makes you think, not the one that makes you lose.
Rules and strategy on the same page
Each board sits above a full explanation of how the game works, the ideas that actually win games, and where the game came from. Learn and play without switching tabs.
Instant, everywhere
Static pages, deferred engine loading and no third-party frameworks in the critical path. It opens fast on a phone on mobile data, which is where most people actually play.
