Astra Go

AstraGo Set a stone on a board rich with wood grain and light, hear it land, and settle into the game. AstraGo brings solo play, learning, and review together in one Go setting. Play KataGo anytime KataGo runs on your device, so you can start a game offline. Choose an opponent level, a 9×9, 13×13, or 19×19 board, and Chinese, Japanese, or Korean rules. Save an unfinished game and pick it up later. Two players, one device Play with someone beside you and set each player's main time and byo-yomi. Lessons and life-and-death problems Learn through board demonstrations and exercises, from the basics and opening to the middlegame and endgame. Choose problems by difficulty, and use hints, trial moves, or answer playback when you need them. Records and review Save and revisit games on your device, or use an empty board to record an over-the-board game. In review, explore win-rate and score trends, key mistakes, AI suggestions, and alternative moves. A board with atmosphere Kaya, walnut, bamboo, ebony, and vermilion lacquer themes bring distinct materials and surroundings to the board. Stones, bowls, lighting, and sound shape the feel of each move, in portrait or landscape. No account is required. Solo play and basic learning work offline. AstraGo has no ads.
