Store description excerpt
Only Move is a whole-board tsumego trainer for the game of Go (Baduk / Weiqi). Every position has exactly one winning move — find it. Every problem is generated and verified by KataGo, the strongest open-source Go AI: one move wins the game, and every alternative loses. No ambiguity, no "good enough" answers — just clean reading practice. 164,000+ PROBLEMS ON TWO BOARDS • About 123,000 problems on 9×9 and 42,000 on 13×13 • Difficulties from 20 kyu to 9 dan, on one shared scale • Ratings are calibrated against real players' results, so a problem's rank means what it says A RANK THAT TRACKS YOU • Your rank is estimated from your recent solving history and updates after every problem • See how your strength reads on the Go server scales you know (OGS, Fox, KGS, EGF and more) • Problems are served at your level — you'll clear about 80% of them LEARN FROM YOUR MISTAKES • Failed problems come back for review right when you're about to forget them (spaced repetition) • Optional reminders when reviews come due • The app learns which kinds of moves trip you up and adjusts what it serves — and your stats page describes those weaknesses in plain sentences EXPLORE EVERY POSITION • After each attempt, review mode lets you play out variations with KataGo's evaluations • Detailed stats: rank history with confidence bands, solving-time trends, and anonymous community comparisons YOUR PROGRESS, EVERYWHERE • A simple account code syncs your history and rank across devices — no email, no password, no sign-up • Free, no ads Whether you're taking your first steps on the 9×9 board or sharpening dan-level reading, there is always only one move.
