Teotihuacan: Expert Challenges is a series of setups intended to challenge players who are well familiar with the game. Book 2 contains two challenges. Decoration Challenge This is a challenge for players who have at least some experience playing the base game. It focuses on decorating the temple as it is being built. Pyramid Challenge This is a challenge for players who have at least some experience playing the base game. The Action Boards are set up so that players can easily build the Pyramid, and the game end is likely to be triggered early due to the finishing of the Pyramid. —description from the publisher
