Ikiwa brings the feeling of a real Go board to your phone: a kaya wood board, clamshell and slate stones, the sound of every move, and a quiet moment when the game ends.

AN AI THAT PLAYS LIKE PEOPLE
• 27 levels from 18 kyu to 9 dan, powered by KataGo's human-style model: the AI plays the moves a player of that rank would play, not a machine's.
• 指導碁 · Shidō-go: like a teaching game with a stronger player, the AI keeps the game close instead of crushing you.
• Japanese or Chinese rules, komi, handicap stones, nigiri.
• Your rank grows with you: an Elo rating that moves with every game, with a chart of your progress.
• Plays entirely on your device. No account, no sign-in.

REVIEW EVERY GAME
• KataGo shows the best moves at any point of the game; try your own variations.
• Timeline shows where the game turned.
• Estimate shows territory and who is ahead.

LEARN FROM CLASSIC GAMES
• Famous games ready to replay, including Shusaku's Ear-Reddening Game, Honinbo Shusai's Retirement Game and AlphaGo vs Lee Sedol.
• Import your own records: SGF, GIB (Tygem), NGF (WBaduk) and UGF (Pandanet).
• Every game you play is kept in your library.

A BOARD THAT FEELS REAL
• Stones sit slightly off the grid and nudge their neighbours, as on a real board.
• Stone sounds: wood, stone, bamboo or ceramic.
• Captured stones go into the upturned bowl lids.
• Open a 3D view of the board and save it as an image.
• Light and dark themes. Available in 9 languages.

KIFU: PLAY ON FROM ANY POSITION (PRO)
• Take a photo of a real board or open an SGF file, and Kifu sets up the position.
• Play on from there against the AI or with a friend, with hints and Estimate.
