Blokus

Blokus is an abstract strategy board game in which 2-4 players take turns strategically placing colored, Tetris-like pieces on to the grid of the game board. Pieces are not allowed to lie adjacent to any of your own pieces, but rather must be placed so that they touch at least one corner of your already played pieces. The player with the fewest remaining pieces after no player is able to play any further is the winner. Receive bonus points for using all of your pieces, however this is a very difficult task.
