Go Game Coach

Go Game Coach teaches you to play Go — from your very first stone to real games on a full board.

LEARN, STEP BY STEP
30 courses and 138 interactive lessons take you from "what is a liberty?" through good shape, life and death, capturing races, and counting the endgame. Every lesson is hands-on: you place the stones and the board answers. Nothing is a wall of text.

AN OPPONENT THAT FITS YOU
A 60-level ladder powered by a neural engine that runs entirely on your device. Level 1 plays gently and gives you chances. The upper levels will test a serious amateur. Move up a rung whenever you're winning comfortably.

A COACH WHILE YOU PLAY
Switch the tutor on and the app follows your game as it happens — warning you before a move that drops stones, naming the shape you just made, and showing where it would have played instead. It explains in plain language, not jargon.

REVIEW AFTER THE GAME
Step back through any finished game move by move and see where it actually turned.

REAL GO, PROPERLY IMPLEMENTED
9×9, 13×13 and 19×19 boards. Chinese, AGA and Japanese rules, with adjustable komi and handicap games. Ko, seki and scoring all handled correctly.

COMPLETELY OFFLINE
No account. No ads. No tracking. No network connection — ever. The engine, the lessons and your progress all live on your device, so it works on a plane, on the subway, anywhere.

Levels 1–20 are free to play, with the tutor free through level 10. One optional purchase unlocks all 60 levels and the tutor at every level. No subscription.

• Cancel a previewed move; pause and resume lesson demonstrations.
• Review: step through every move more easily.
• Play from here starts before your own move and keeps the earlier analysis.
• Move grades made while you play are kept, so Review opens almost fully analysed.
• Many smaller fixes and improvements.
