Ancient strategy game. Surround territory, capture stones, score more to win!
Go is one of the oldest and most profound strategy board games in human history, originating in China over 3,000 years ago. Two players alternate placing black and white stones on a grid, aiming to surround more territory than their opponent. Stones that are completely encircled by enemy pieces are captured and removed. Despite having deceptively simple rules, Go produces extraordinary strategic depth, with more possible board positions than atoms in the observable universe. This browser version lets you play against an AI opponent on 9x9, 13x13, or 19x19 boards. The 9x9 size is ideal for beginners seeking shorter games, while the full 19x19 board offers the classic professional experience.
