As princes in Machu Picchu, players hope to protect their city from being discovered by Spanish invaders. They have 9 days to call the Sun God for help by sacrificing llamas and other goods. By organizing their economy well, they can hire enough Priests and Virgins to perform sacrifices. The player who offers the most effective sacrifices will win. However, if time runs out and the gold-hungry Spaniards arrive, then richer players might win instead!
