Choose a board layout.
One player has white stones, the other player has black.
To start, Black covers any space marked "2".
From then on, starting with White, the players take turns.
On your turn, cover up to X empty spaces marked "X". For example, you could cover any 3 empty spaces marked "3".
End of Game
The game ends when the board is full. The player with the largest contiguous group of stones wins. If tied, compare the players' second-largest groups, and so on, until you come to a pair which aren’t the same size. Whoever owns the larger wins.
Note that a tie is impossible.
