Lessons, tsumego puzzles and games against a computer opponent, with a tutor that can see the board and explain any move the moment you ask.
Miss a puzzle and you can ask what went wrong. The answer is grounded in what a Go engine actually reads in that position, not in a guess about it.
No streaks, no timers, no leaderboards, no badges. Wood, stone, paper and ink, and a board that holds still while you think.
