Go Problems (Tsumego): Life, Death & Captures

Read the local sequence until a group is unconditionally alive, dead, captured, or dependent on ko; liberties and legal recaptures are verified.

Daily Puzzle

One puzzle per game each day — the whole site solves the same one. Finish any daily to light up the calendar and extend your streak; complete a full month for its medal. Yesterday's puzzle stays open for 48 hours, and every full week banks a streak freeze that saves you automatically.

Puzzle Journey

Each game gets its own path: chapters of ten levels, easy openings, sharper endings.

The last level of every chapter is a boss puzzle — no hints, one mistake allowed. Clear it to earn the chapter medal and unlock the next. Boss puzzles never wait for unlocks: challenge any chapter's boss directly and win to skip ahead, so strong players don't have to grind up from the easiest levels.

Practice

The full calibrated pool is open for practice — far beyond the levels used by the journey. Pick a difficulty and theme, get unsolved puzzles first, and roll into a review round once you have cleared them all; stars and points count as usual.

How it works

Stars — Solve clean — no errors, no hints — for three stars; at most one error and one hint earns two; finishing earns one. Spend stars to skip a stuck regular level.
