Sudam Tsumego: Go Life & Death

318 original Go life-and-death problems. Free to download: the 106 problems in levels 1–2 are free. One purchase (not a subscription) unlocks all 212 problems in levels 3–6 plus every problem added later. No ads, no sign-up, no daily limits, and problems work offline. · Six levels: 1 Intro · 2 Basic · 3 Novice · 4 Intermediate · 5 Advanced · 6 Expert. · Real sequences: play the right move and White keeps resisting to the end; play a wrong one and White shows the refutation. · Four-step hints: where to look → three candidates → the first move → the full solution. · Check your level: a free 12-problem placement test and a 10-problem test for each level. Levels are the app's own difficulty steps, not official ranks. · Missed problems are collected for review. · Every problem was proven by an exhaustive search program (exactly one correct first move) and double-checked with the open-source Go AI KataGo. · No account.
