Ultimus (2005)

Each player has 12 wooden blocks (3 each of 4 different sizes) which all have a triangular base but with each corner having a different height. The goal is to be the player who is able to go last. You cannot place a piece of the same size as the previously placed piece.A placed piece must have a side touching a side of the piece placed before and with one edge matching the height of an adjoining edge.
