Go 碁 – AI Go Studio

Go 碁 – AI Go Studio lets you play Go against an AI, review your games and learn the game on iPhone and iPad. Free, no ads, no account — every feature is included. ■ AI opponents from 20 kyu to 9 dan The AI plays like people of each rank, strengths and mistakes included. Pick "Strongest" and it plays at full strength, beyond professional level. ■ Career mode Three placement games let the AI estimate your strength. Then you play the AI at your own rank: wins, win streaks and good moves earn experience, and a full bar takes you up one kyu or dan, with a celebration to match. Your rank grows as a tree, from a sprout to an ancient giant. Free play and your career game are each kept, so you can switch at any time. ■ Live hints and analysis Turn on hints to see the AI's suggested moves with win rates and search counts, colored by how many points each move loses against the best one. The influence view shows each side's territory and strength. ■ Learn as you play Every move is explained: atari, double atari, captures, connections, cuts, groups in danger or now alive — and whether the move was best, good, slack or a mistake. ■ Forest board Go becomes a forest: black stones are trees, white stones are flowers, and empty points are lakes. Plants drink from the water beside them and wither when their last water is sealed off — an intuitive way to understand liberties and captures, great for beginners and kids. ■ Review your games Step back and forth freely and try a different move anywhere. At the end, the AI judges dead stones and counts the score. ■ Runs on your device The AI thinks on your iPhone or iPad. No internet needed, and your games are never uploaded. ■ 7×7 to 19×19 boards, 8 languages English, 繁體中文, 简体中文, 日本語, 한국어, Español, Deutsch, Italiano. Go 碁 is made by an independent developer. If you enjoy it, you can sponsor its development; sponsoring unlocks no content or features.
