Store description excerpt
Goban3D brings the ancient game of Go — also known as 囲碁 (igo), 바둑 (baduk), or 圍棋 (wéiqí) — to iPhone and iPad. Play on a beautifully rendered 3D goban or switch instantly to a clean 2D board. Local matches, private online games with friends via Game Center requested matches, and the world's strongest Go AI, KataGo, all in one app. Whether you've never placed a stone before, want a private match with a friend or club-mate, or are ready to test your skills against the strongest Go engine on the planet — Goban3D is for you. KATAGO AI (FREE, 100% OFFLINE) • The world's strongest open-source Go engine, running natively on Apple Silicon — no internet, no account, no data sent anywhere. The AI is fully on-device • Board sizes 9×9, 13×13, and 19×19 • 26 skill levels: 20 Kyu (complete beginner) through 5 Dan, plus full-strength AI for serious study • Weaker levels use KataGo's Human-style network (trained on human games) so the AI plays like a real person at your rank — not a crippled superhuman • Full-strength mode runs the latest strongest KataGo network published on katagotraining.org as of 15 April 2026 • There's an old Go proverb: "Lose your first 50 games as quickly as possible." Start on 9×9 at 20 Kyu — after 2 or 3 games, winning comes easier than you might think. Each time you win, raise the skill by 1 or 2. KataGo is the best Go teacher ever built, and it speaks every language ONLINE PLAY WITH FRIENDS • Private matches over Game Center with people already in your contacts • Invite a specific friend — no public matchmaking, no strangers • All online games are untimed — take your time and enjoy the game LOCAL PLAY • Two players on one device, pass-and-play • Board sizes: 9×9, 13×13, 19×19 • Handicap stones (0–9) with automatic komi adjustment • Japanese scoring with 6.5 komi — mark dead stones, confirm the score • Untimed by default — take your time and enjoy the game BOARD & VISUALS • 3D board powered by RealityKit — physically-based materials, 60 fps animations for every placement and capture • Instant 2D mode in SwiftUI for low-power play • 4 board textures, 8 stone textures, multiple ground and gridline options — all free • Haptic feedback and authentic wooden stone sound effects • NHK broadcast-style move announcements with optional Go terminology (atari, tsuke, hane, nobi...) ACCESSIBILITY — GO FOR EVERYONE Goban3D makes Go genuinely accessible — across ability, skill level, device, region, and language. No other Go app on the App Store declares any accessibility features. Goban3D has 100% coverage across all seven Apple categories: VoiceOver with full board-position labels, Voice Control, Dynamic Type, Reduce Motion, Reduce Transparency, Sufficient Contrast, and Differentiate Without Color. The app starts in 2D by default, and the 2D SwiftUI board is where the full accessibility stack lives — including complete VoiceOver board navigation. When VoiceOver is on, the 3D toggle is disabled to keep the accessible experience front and cent
