• Opens faster when you have a game in progress — the board appears right away and the AI engine (KataGo) loads just after the first screen is shown • Lighter startup — the heavy AI engine and the first-run device check no longer run before the first screen, for better stability

New: Life & Death Analysis • Place stones and KataGo judges every group as alive, dead or unsettled • See the vital point, candidate moves and the follow-up sequence move by move • When confidence is low it says “Uncertain” instead of guessing — this is an AI judgment, not a mathematical proof • 3 full analyses free every day; verdicts stay free after that. Unlimited with Sudam Pro Before your first game we ask your level once and give newcomers handicap stones. • Fixed an issue where the AI engine (KataGo) did not load properly on iPhone.

• The price of the Pro models (b18, b28) now appears on Home, Review and Settings. No more buttons that never said what they cost. • The Pro model can now be bought on the Chinese App Store. If you already had it, nothing is taken away. • Fixed the price running off the edge of the screen on devices set to larger text. • Fixed Pro status being shown incorrectly when the store region could not be determined. No account, no internet, and your games never leave your device.

Games now finish cleanly, all the way to the count. • The AI now passes when the game is over, so games end with proper scoring • Dead stones are marked automatically — tap a group to fix it if needed • A result card shows stones, territory and komi at a glance • Finished games are saved automatically, and you can jump straight to your 3 biggest mistakes • One tap on "Play AI" on the home screen starts a 9×9 game

Small improvements. • The App Store now lists the languages the app actually supports (Korean, English, Japanese, Simplified and Traditional Chinese) • Adjusted when we ask for a rating — never during a game or on the purchase screen No account, no server, no ads. Everything stays on your device.

Sudam is now listed under Education. The 12 rule lessons, 320 life-and-death problems, and AI game review remain unchanged.

· Fixed the AI answering your first move before the engine was ready. It now plays at full strength from move one. · The board shows 'Loading engine' while the engine starts.

· Pro networks (b18/b28) are now available for purchase in Taiwan, Hong Kong and Macao. · We now ask for a review only after you've played on a few separate days. · Small stability fixes.

Fixed the app failing to open on iOS versions below 18. • On iOS 15–17 the app quit the moment it launched — a system library compatibility problem. It now starts normally on those devices • Apologies to everyone who couldn't get in No account, no server, no ads. Everything stays on your device.

Proper iPad support. • Until now iPad ran the iPhone screen scaled down. The board is now sized for the iPad display • On wide screens the content is centred so it stays comfortable to read • Fixed the win-rate bar being misaligned during a game

Fixed a crash that could close the app right after opening. • The AI engine now loads when you start a game or a review — not at launch. Home, Learn and Settings no longer load the neural network • Faster start, lower memory use If it still closes on your device, please tell us your model and iOS version in a review.

Both issues raised in your reviews are fixed, and Traditional Chinese is now supported. • Fixed the AI playing seemingly random moves — the per-level candidate-move selection was rewritten and search volume increased • Lesson mode now switches black↔white automatically after each stone (can be turned off in Settings) • Traditional Chinese added — Taiwan, Hong Kong and Macau now see the app in Traditional Chinese • Fixed SGF import failing silently Note: this version requires iOS 15 or later.

Fixed the AI playing seemingly random moves. • Fixed a move-selection bug that made the weakest candidate get picked at lower levels • The AI now only plays moves it actually searched • Difficulty now means "how much win rate it may give up", so levels feel distinct (Lv.10 always plays the best move) • Slightly deeper search; new games now default to Lv.7 Thanks to the reviewer who reported this.

• One-time review prompt after your first finished game • Stability improvements
