Independent Life

The Game End

  1. If the players agree, they remove stones accordingly. Else they consider the connected regions that are adjacent only to one player's independently alive strings and that consist of intersections being empty or having opposing not independently alive strings on, which they remove.

  2. A player's territory is the number of intersections of connected empty regions adjacent only to his strings.

  3. The score is Black's territory plus prisoners of white colour minus White's territory, prisoners of black colour, and the komi.

  4. Black wins if the score is greater than zero. White wins if the score is smaller than zero. The game is a tie if the score is zero.
