Pentwall

Pentwall is an abstract strategy game using pentominoes. Two players take turns choosing one of 12 different pentomino shapes to fill a shared 10x10 playing area with that shape of their color. Pentomino shapes can be rotated and flipped. Once a pentomino shape is used, it may not be used by either player again. The game ends when no more pentominoes can be placed or when all pentominoes have been used. The player gains the territory of any area not occupied by pentominoes that has more squares of his/her own color in contact with it than his/her opponent. The player with the largest total territory size wins. This game is distributed for free as a PnP game.
