Mindful Chess: Chess Puzzles

Mindful Chess is a comprehensive chess training platform designed to help you practice tactics, master your opening repertoire, and elevate your board vision. Solving puzzles quickly earns bonus points, but the game always rewards careful calculation over guessing. The core puzzle mechanic is simple: a wrong move costs you points from your potential score. This trains you to find the right move instead of just trying one. 100% OFFLINE — POWERED BY MINDFUL ENGINE Every feature runs on your device: the puzzles, the opening lessons, the analysis board and the bot itself. Mindful Engine is a chess engine written from scratch for this app, so there is no third-party server anywhere in the loop. Put your phone in airplane mode and the whole app keeps working. FEATURES • NEW! Daily Puzzle — Free for Everyone: One hard puzzle a day, the same for every player in the world, with a single attempt. The clock starts the moment the board is revealed and the fastest solve tops the leaderboard — each mistake adds 20 seconds. Build a streak, share your result, come back tomorrow. Works offline like everything else. • NEW! Opening Trainer — Openings That Actually Stick: Every line is first walked through with move-by-move explanations, then you play it back yourself on the board. A spaced-repetition system remembers exactly which move you struggle with and brings it back just before you would forget it. 89 variations across 26 major openings, from the Sicilian and the London System to the Catalan and the Benko Gambit — and you can train any line from either side, playing the Najdorf as White or as Black. A daily review badge shows what is due. Starter lines in the Italian Game and the French Defence are free to try; the full course unlocks with Pro. • NEW! Analyze Position (Pro): Set the pieces up however you like, then see the best move and a full evaluation. Illegal setups are prevented as you build them. Play the suggested move — or any legal move — and the engine instantly shows the best reply for the other side, so you can walk a whole line through. One tap continues the position against the bot. • Three Bot Difficulties — Free: Beginner, Club and Master, all running entirely on your device. The bot opens from a real opening book and only starts making mistakes once the opening is over — because that is when real players start making them. • Hint Button (Pro): Stuck against the bot? One tap draws the best move straight onto the board. • Opening Encyclopedia (12,000+ Lines, Pro): Don't just memorize openings — play them. Explore a database of over 12,000 openings and variations, with its own search, sitting beside the Trainer in a single Openings hub. • Live Match — Face-to-Face Multiplayer: Challenge a friend in the same room. Two devices connect directly over your local network, no internet required. Choose your color, pick your time control (3, 5 or 10 minutes, or untimed), offer draws, resign with honor, and settle it with instant rematches. • Over 1 Million Offline Puzzles: Practice anytime, anywhere, with no connection needed. • Polished Board Experience: Pieces glide smoothly, legal moves light up when you pick up a piece, and every move answers with crisp sounds and haptic feedback. • Game Center: Two leaderboards — your all-time score, and the daily race (requires internet to sync). NO ADS. NO ACCOUNT. NO TRACKING. Puzzles, opening lessons and your progress stay on your device. There is nothing to sign up for and nothing to opt out of. LOOKING FOR A BIGGER CHALLENGE? Push your limits with the Mindful Chess Advanced Pack and unlock an additional archive of 1.7 million master-level (1800+ Elo) puzzles. Thanks to our Smart Storage technology, this giant database is downloaded only when you unlock it, keeping the initial app download incredibly light.
