A new chess puzzle every single day, set on a real board. Spot the fork, land the mate, save the endgame — one sharp move at a time. If you want to actually get better at tactics instead of just playing more games, this is your daily rep. Most chess apps drown you in endless problems and walk away. This one gives you one focused puzzle a day, escalating hints that nudge you toward the idea without spoiling the solve, and short lessons that teach you how to SPOT each pattern — so the next time it appears on your own board, you see it. WHAT YOU GET - One fresh tactics puzzle to solve on a clean, tappable board every day - Escalating hints that guide you to the winning idea without giving it away - The eight core patterns explained: forks, pins, skewers, sacrifices, discovered attacks, deflection, mate-in-one and endgame technique - Practice mode to drill any theme on demand and cement the pattern - A growing streak, estimated rating and clean-accuracy score that show real progress - Full-color board themes and instant haptic feedback, working completely offline PERFECT FOR - Beginners who know the moves but keep hanging pieces - Club players grinding to push their rating higher - Busy people who want a five-minute brain workout each morning - Anyone rebuilding their tactical eye after time away from the board WHY NOT JUST PLAY MORE GAMES? Games hide the lesson inside 40 moves of noise. Puzzles isolate the exact moment a tactic wins, so you train the pattern directly — the fastest, proven way to raise a rating. PRIVACY No account, no sign-up, no tracking. Your solves, streak and stats live on your device. FULL ACCESS The daily puzzle is free forever. A subscription unlocks everything else: all 30 themed puzzles, unlimited hints and full solutions across every tactic, plus full progress and rating tracking.
