Gu is a two player strategy board game.Two players alternate turns to paint squares on a 11x7 grid. Only squares adjacent to other squares of the player's color can be painted. Each turn the players paint an increasing number of squares: first red player paints 1, then blue 2, then red 2, then blue 3, etc. An area surrounded completely by squares of the same color will be automatically painted. The game ends when all the board is painted, and the player with more squares wins.
