A unified client to play on multiple Go servers and solve puzzles in a variety of modes.

Whether you have never placed a stone or you are sharpening your reading, everything is here, offline, with no ads and no accounts required. LEARN FROM ZERO • Eight interactive lessons take you from the very first stone to scoring a finished game: liberties and capture, atari, saving stones, illegal moves, the ko rule, life and two eyes, and territory. • Every lesson step is hands-on — you play the move yourself. 500+ PROBLEMS TO SHARPEN YOUR READING • More than 100 problems at each of five difficulty tiers: Novice, Easy, Normal, Hard, and Expert. • Capture, atari, escape, connection, and life-and-death (tsumego) — including snapbacks and vital-point shapes. • Your progress is tracked so you always know what is left. FIVE LEVELS OF AI • Play full games against opponents from gentle beginner to a Monte-Carlo Tree Search engine that actually reads ahead. • Choose your color, add handicap stones, and play on 5×5, 7×7, 9×9, 13×13, 19×19, or 21×21 boards. PLAY PEOPLE • Game Center for online matches. • Local-network play over your Wi-Fi or wired network using Bonjour — no internet or account needed.
