About the Game

Summetry is a drawless self-stalling game for two players: Black and White. It is played on the hexes (cells) of an initially empty hexagonal board. The recommended size is 5 cells per side, but boards of 3 to 7 are also valid. Each player has access to a sufficient supply of stones of their own color.

Definitions: A group is the maximal set of connected stones of the same color. A single stone is also a group. The size of a group is the number of stones it contains.

Turns:Black plays first and then turns alternate. On your turn, perform the following actions in the order listed:

Place a stone of your color on an empty cell not adjacent to any friendly group, unless the group formed by the placed stone touches at least two enemy groups whose total sizes are at most equal to the size of your new group. Remove from the board all enemy groups adjacent to your new group whose total sizes are exactly equal to the size of your new group.

End of the game:The game ends when a player cannot place any stones; in that case, that player wins.
