Go

Master the ancient game of Go with Go, a world-class digital opponent powered by award-winning AI technology. Whether you're a complete beginner or an experienced player, Go delivers an authentic, challenging experience that will sharpen your strategic thinking and tactical skills.

Go features the legendary Aya Engine—a two-time international gold medalist in computer Go competitions—tuned to play across 10 difficulty levels from 18 Kyu to 3 Dan. This means you can start at your own level and progress steadily as your skills improve. The engine has been refined over three years of development and now plays 10 grades stronger than previous versions, delivering the most formidable AI opponent available on mobile.

Play full games on 9x9 and 13x13 boards, perfect for quick matches and skill building. The free version includes a 180-move limit on 19x19 boards (the traditional competition size), while the paid version unlocks unlimited play on all board sizes. You can also challenge a friend using the 2-Player Hotseat mode for direct head-to-head competition on the same device.

Go supports both Chinese and Japanese rulesets, plus handicap systems so stronger players can compete fairly with beginners. Built-in hints at 1 Dan level help you develop winning patterns and deeper understanding of the game's strategy. The comprehensive help section walks you through the fundamentals and links to authoritative teaching resources, making it easy to learn whether you're picking up Go for the first time or refining your technique.

Designed for both tablets and phones, Go adapts beautifully to any screen size, whether you prefer playing on the go or at home. The free version is supported by ads, which may use your internet connection; the paid upgrade removes ads entirely. Permissions for photos, media, and files allow the game to save your progress securely and cache content for smooth gameplay.

With its elegant simplicity and infinite tactical depth, Go has captivated strategic minds for thousands of years. Start your journey to mastery today with Go.
