Pyrinoes

Pyrinoes is a game for two players that combines two game systems: double-six dominoes and Looney Pyramids. Players begin the game with a supply of dominoes and two colors of pyramids. Players take turns adding pieces from their supply to the chain of played pieces, either by placing dominoes or by creating a "pyrino" out of pyramids. When one person runs out of pieces, the round ends, and the winner scores points. Subsequent rounds are played until one player has earned 100 points. Pyrinoes adds strategic depth to classic Dominoes by giving the players the ability to create a desired piece, but at the risk of revealing critical information to the opponent.
