Blindfold Chess App

Blindfold Chess App is a web-based tool built for players who want to train their visualization skills by playing chess without seeing the board. Developed by Romir Patney and launched in mid-2025, the app uses a touch-based input system combined with audio feedback so you can make moves eyes-closed and follow the game entirely by ear.

What sets this app apart is its multi-board support. You can run simultaneous games on up to 64 boards at once, making it a serious tool for players who want to push their blindfold skills to the extreme. It integrates the Stockfish engine so you can practice against AI at adjustable difficulty levels, and supports Chess960 (Fischer Random) in addition to standard chess. The app also supports game controllers and custom keyboard button registration for full accessibility.

Beyond solo training, the app includes a streaming mode that lets you share a live game ID for remote or local relay viewing. This made it a standout tool at the Tata Steel Chess tournament in January 2026, where it was featured for simultaneous blindfold exhibition play. The app is a progressive web app (PWA) so it installs on any device without an app store, and it works offline. It appears to be free to use.
