A new dimension for Blokus

The goal is to cover as much of the board with your pieces as possible.

Each new piece must touch at least one other piece of the same colour, on the corners only! Pieces of the same colour cannot be in contact along an edge. However, pieces which are not of the same colour can touch along the sides.

WHen all players are blocked, each one counts the number of triangles they were able to place on the board. The winner is the player who has the most number of triangles on the board.
