Sit down at the board, and your teacher is already there. Sudam is a fully offline Go (Baduk) app with KataGo — the world's strongest open-source Go engine — built right into your device. No internet, no sign-up, no server. 1. World-class AI, fully offline The KataGo engine lives inside the app, analyzing and responding instantly without a network. Every calculation happens on your device — and only on your device. 2. 27 levels, from 18-kyu to 9-dan Find the opponent that fits you on a finely graded 27-step ladder. Handicap games from 2 to 9 stones, adjustable komi, your choice of Black or White, and scoring under Korean rules. 3. Teaching Games with AlphaGomi Your AI teacher AlphaGomi compares your move with the best move every single turn, explaining the type of move, why it works, and how the game is likely to unfold — in clear, friendly language. 4. Review — down to "why that spot" Step through your game move by move and spot the turning points on the win-rate graph. In Explore mode, replay the AI's recommended lines or try your own ideas and judge the position. 5. Go proverbs, right when they apply In moments like atari, cuts, life & death, or a big group in danger, the Ten Golden Rules and time-honored proverbs appear one line at a time — so the principles sink in naturally. 6. Daily tsumego and Rank Challenges Fresh puzzles every day reveal your strengths and weaknesses by theme — life & death, atari, cutting, and more.
