Black plays first. Take turns placing stones on the intersections of the grid lines.
Enclose empty intersections with your stones to claim territory. Corners are easiest to secure.
Surround enemy stones to remove their liberties (adjacent empty points) and capture them.
When both players pass, count territory and captures. The player with more points wins!
