Das Gold der Maya

The object is to collect a full disc of pie shaped wedges of an Aztec Calendar. Each round you bid on a differently-shaped wedge, and you can see the next 2 pieces up for auction. Add a couple of twists in that certain pieces can only be placed next to certain other types of pieces, and the pieces are two sided (you may use either side), and you have a bidding game. - BoardGameGeek
