AI Go King is one app for playing Go against AI, replaying professional games and solving tsumego (life-and-death problems).
■ On-device AI that works offline
• KataGo, an open-source Go AI, runs directly on your iPhone, so you can play on a plane or on the subway without an internet connection.
• Choose how deeply the AI thinks: Fast, Standard or Deep. More thinking makes it play stronger.
• The AI resigns once the game is clearly lost.
■ Cloud AI from 18 kyu to 9 dan
• Pick your opponent's rank: 18k, 15k, 12k, 9k, 6k, 3k, 1k, 1d, 3d, 5d, 7d or 9d.
• Turn on "Play like a human" and the AI plays the way a person of that rank would.
• With it off, you face the Strongest AI at full strength.
• A live win rate shows who is ahead.
■ 1:1 with a friend
• Take turns on one iPhone. No points needed.
■ Game settings
• Board size 9×9, 13×13 or 19×19
• Even game or a handicap of 2 to 9 stones, with your choice of komi
• Korean, Japanese or Chinese rules
• Play Black or White and name your game
■ Help during the game
• Ask for a hint to see the move the AI recommends.
• Estimate the position to see the current score difference.
• Undo is free 3 times per game.
• Confirm each move with a second tap so a stray touch doesn't place a stone.
• When the game ends, the AI counts the territory and shows the result.
• Games save automatically. Use "New game from here" to branch off at any position.
■ Pro game records
• Browse the latest professional games and search by tournament or player.
• Step through a game move by move, jump 5 moves at a time, or use auto play.
• Records with AI analysis show Black's and White's win rate for every move.
• Position estimates in game records are free.
• From any position, keep playing against the AI.
• Reopen your 5 most recently viewed game records right from the lobby.
■ Tsumego
• Train your reading with Beginner, Intermediate and Advanced problem sets.
• Solve each problem by placing stones on the board. The app saves your accuracy and history. Viewing answers is free.
■ Points
• Get 100P when you first sign in, plus a check-in bonus on your first visit each day.
• An AI game costs 10P, a hint 5P, an in-game estimate 5P, and undo 5P from the 4th time in a game.
• Points never expire and free points are spent first. Buy point packs in the app when you run low.
• 1:1 games, pro game records, estimates in records and tsumego answers are free.
■ Account
• Start right away without signing up. Link an Apple or Google account to keep your point wallet.
