starweb board Rules
The game starts with a pie and the players, black and white, take turns to place one stone on a vacant cell.
Like coloured connected stones form a group. A group containing 'n' corners is worth 'Σn' points.

Σn equals n+(n-1)+(n-2)+...+1 and is called the 'triangular score'. It means that of a group containing corners the first corner is worth 1 point, a second is worth 2 point, a third 3 points and so on. A group containing 4 corners is thus worth 1+2+3+4=10 points. A formula for Σn is: n*(n+1)/2.

A player may pass without losing the right to move next turn. The game ends when both players pass on successive turns.
The winner is the player with the highest score. If scores are equal, the player who placed the second stone on the board wins.
