Bre-e-edge

From BluWiki

The board must be completely full, and when it is, the red stones must have more points than the blue stones. Points are assigned as follows: A color receives X points for every one of its stones occupying an edge or corner space, and -Y points for every separate group of that color on the board. The pattern inventor sets the values for X and Y. A �group� may be any size, as small as a single stone, and it may contain stones occupying edge points. The tallies for �edge� points and �group� points are independent, so edge stones will be counted twice. An example is given using the figure below.

Let�s say that the pattern inventor set X=1, and Y=-3.

Red has (17 edges stones)*1 = 17

Red has (3 groups)*-3 = -9

17-9 = 8

Blue has (19 edges stones)*1 = 19

Blue has (10 groups)*-3 = -30

19-30 = -11

So the red stones have 8 points, the blue stones have -11, and the builder wins.
