Play full chess games against the Stockfish engine without seeing the board. DarkSquares lets you choose exactly how much of the position stays visible, so you can build blindfold skill gradually instead of jumping straight to a blank board.
Five board-visibility modes take you from training wheels to fully blindfold: the full board, faded pieces, plain disks, an empty grid you fill from memory, and a completely blank board where you track every piece in your head. Set the opponent across eight Stockfish difficulty levels, from a gentle beginner to a strong engine. Enter your moves three ways: tap the pieces, type algebraic notation, or speak them aloud with voice input. Every finished game is saved to your history when you are signed in, so you can replay it move by move and share it. No signup is required to start a free game.
If full games feel out of reach, structured blindfold chess training builds the skill step by step, from square colors and coordinates to the games on this page.
Play a complete game without seeing any pieces - type or speak your moves
Blindfold chess is ordinary chess played without seeing the pieces: you hold the whole position in your head and announce each move in notation. On this page you can play a full game online against the Stockfish engine, free and with no sign-up. Choose how much of the board stays visible, from the full board down to faded pieces, plain disks, an empty grid, or a completely blank board, so you can build visualization step by step instead of going fully blind on day one. Set the opponent across eight difficulty levels and enter your moves by tapping the board, typing algebraic notation, or speaking them out loud. The rules are exactly those of standard chess; only your sight of the board changes.
Strict mode
The board can't be revealed during the game. No peeking when your memory slips. Required for the Pure Blindfold achievements: only strict games from the standard starting position count.
