The essentials
- A local engine can play a complete game without sending the board to a server.
- 9×9 is ideal for learning, 13×13 for compact games, and 19×19 for full Go.
- Offline play improves privacy and works while travelling or without reliable reception.
- Strength and thinking time depend on the device, board, and chosen level.
What offline should really mean
The position stays on your device and the computer calculates its move locally. No game account is required for an ordinary match. Store restoration or optional cloud features may still need an Apple connection.
Look for precise explanations rather than a vague offline promise.
Choose the right board size
9×9 brings fights to the point quickly and is ideal for learning liberties, groups, and territory. 13×13 creates more strategic space without the length of a full game. 19×19 is the international standard and rewards long-term planning.
A strong app keeps the rules consistent while adapting presentation and thinking time to the device.
Strength labels should be honest
Kyu and dan labels are useful orientation, not an official certification of a computer engine. Hardware, time limits, and the position itself all influence effective strength.
For a beginner, the strongest possible reply is not always the best experience. Clear levels, visible thinking, and a dedicated learning mode are often more valuable.
Kanso Go as one concrete option
Kanso Go runs ordinary computer games with a KataGo-based engine directly on iPhone and iPad. Its tutorial and Kanso Focus also work without a Kanso account. Free includes 9×9 and 13×13; Premium adds 19×19 and stronger levels.
The app contains no advertising. Premium is an optional one-time purchase, not a subscription.
