Deep within the rain forests of the Yucatan, rival teams of treasure hunters have recently discovered the lost city of Codinca. In the center of the once great citadel stands a stone temple. Local legends tell of great treasures that lie buried beneath the temple, but despite many weeks of searching no doorway has been found.
On the top of the temple stands a square stone altar. A small totem stands in the center of this, surrounded by a pattern of sixteen carved tiles. Examining them closely you discover an intricate series of mechanisms which allow the tiles to switch places and turn over, which reveals that each tile has a stone side and a gold side. Carvings on each side of the pillar indicate that a sequence of four key patterns must be made with the tiles to open the temple. Can you be the first to unlock the secrets of Codinca?
