Chess Ta!
Offline chess with an NNUE engine, a real 3D board, and analysis tools.
NNUE neural network MMC Solo Dev
The engine
The evaluation is an NNUE neural network — 256 hidden units over 768 input features, quantised int16, QA 255 / QB 64 — written in C and compiled straight into the app. It is trained from self-play by a Go trainer, quantised to 16-bit integers, and evaluated incrementally so the search can afford to call it at every node.
The rules of this variant
Standard chess, plus Chess960 (Fischer Random). Eleven opponent tiers run from a deliberately gentle beginner up to a full-strength engine, so the same app works for someone learning the moves and someone studying an opening.
What you get
- Play offline against eleven difficulty tiers, from beginner to full strength
- A real 3D board rendered with three.js, alongside the classic 2D board
- Analysis board with an evaluation bar and Best Move hints
- Game review: step through a finished game move by move
- PGN library — import, browse and review your own games
- Custom position setup, pass & play on one device, and AI vs AI
- Board and piece themes, and full offline operation
