1. Each player owns 2 stone colors. To start, Player 1 places one stone of either of her colors on any empty space.
2. From then on, starting with Player 2, the players take turns. On your turn, you must place 1 or 2 stones, in any combination of your colors, on any empty spaces.
3. After you place your stone(s), capture all smothered enemy groups, and then capture all overgrown enemy groups.
4. The first player to have captured X enemy stones wins.
