Turn based strategy board game that involves you trying to conquer as many squares on the board as possible. Simple, or is it?

Squares are captured by placing a game piece down. The squares adjacent to your game piece are also captured. You can place up to 3 game pieces on any one square.

Red highlighted squares mean your game piece is being threatened for destruction on the next turn. You can remove the threat by adding another game piece to the threatened square or one of its adjacents.
