ChessBlind

Welcome to ChessBlind — where you train the one skill that separates strong players from the rest: seeing the board in your head. Here's how it works. Study a position, memorize it at your own pace, then watch the board disappear. Now solve it from memory, on a completely empty grid. Sounds tough? It is. It's also exactly how titled players build calculation, pattern recognition, and real board vision — the kind you can't get by staring at pieces the whole time. Lead with a clear mind. Study the position, no timer pressure. Watch the board vanish. Solve the puzzle purely from memory. Get stuck? Three levels of hints, from a gentle nudge to a full reveal. Get Socratic coaching that guides you to the answer instead of just handing it over. Progress through a full campaign, from Pawn to King, earning up to 3 stars on every puzzle along the way. Most puzzle apps test your memory with the board sitting right in front of you the whole time. ChessBlind takes the board away — so you're training the real skill, not just memorizing one position. Features: * Study and solve blindfold puzzles * Three-level hint system * Socratic coach that guides instead of spoiling * Full campaign mode with star ratings * No account needed * Runs entirely offline, on your device * Your stats and history stay private, always Your board vision is a muscle. The only way to build it is to stop looking. Open ChessBlind and see how far you can go without seeing the board at all.
