GoSphere

GoSphere — where every stone shapes a universe.

Powered by the KataGo neural-network engine and wrapped in Eastern Go aesthetics, GoSphere is a pocket dojo for players of every level — from those placing their first stone to veterans roaming the full 19×19 board.

【THREE WAYS TO PLAY】

· Master Challenge: Duel phantom masters, each with a distinct style and personality. Pick your opponent, choose your color, and let the conversation in stones begin.

· Free Training: Customize board size, AI strength, ruleset, komi, and handicap. Focus purely on the art of hand-talk.

· Local Pass-and-Play: Two players, one screen. Flip the board, sit face to face, and play purely — no AI in the way.

【DEEP KATAGO REVIEW】

See live win-rate, candidate moves, and an influence heatmap as you play. After the game, one tap launches a full AI review that grades every move — so each game becomes a stepping stone to growth.

【RANK JOURNEY: 20 KYU → 9 DAN】

Start at 20 kyu and climb your way to amateur 9 dan. Every promotion is earned in the Assessment Hall through a real trial. Fill your insight, break through, and ascend step by step.

【FIVE-DIMENSION SKILL PROFILE】

Based on your recent win-rate curves, GoSphere builds a profile across opening, midgame, endgame, stability, and pressure resilience — showing exactly where you shine and where to improve.

【ACHIEVEMENTS & MEDALS】

Dragon Slayer, Flawless Tactician, Comeback King, Board Years — each medal chronicles a legend in your Go journey.

【SGF STUDY ROOM】

Import SGF records and review them side by side with AI. Study the classics, stand on the shoulders of giants, and survey the full landscape of the game.

【IMMERSIVE CRAFT】

Hand-crafted board textures, multiple stone materials, authentic placement sounds, and a dark immersive theme — every stone falls with weight and ink-like flow.

【FAIR & FLEXIBLE ECONOMY】

Qi drives your games; crystals refill it. Earn crystals by watching ads or through optional in-app purchase — no paywall, your pace.
