Hardcore Blindfold Chess

Blindfold Chess hides the board and asks you to keep the position in your head. Tap the empty board, type your move or just say it, and hear the computer's reply read out loud. PLAY YOUR WAY • Three modes: Peek (hold the board for a moment, every peek counted), Hidden (no board, the move list helps) and Pure (no board, no move list). • Five opponents from Casual to Master, with a time limit and openings to start from if you want them. • Hands-free: it listens again by itself after each reply. Say "repeat", "take back" or "where is my knight?" • Takebacks, illegal moves and board questions are counted next to peeks, so a clean win means a clean win. TRAIN YOUR VISUALISATION • Blindfold puzzles: mate in 1, 2 or 3, plus a new puzzle every day. • Square colours, knight and bishop routes, and remember-the-position drills. • Famous games played move by move, with no board, and questions along the way. SEE YOURSELF IMPROVE • A blindfold rating, badges and a daily streak. • Step through any finished game and see the moments you lost track. • Open a game in Lichess for engine analysis, or export every game as PGN. • Share a picture of your result. PRIVATE BY DESIGN No account, no ads, no tracking. Your games stay on your device. Voice input uses your phone's built-in speech recognition.
