In Tzolk'in: The Mayan Calendar - Tribes & Prophecies, players now becomes the leader of a certain tribe, each of which has a special ability that only that player can use. The game has 13 tribes to offer plenty of variety, (You know that 13 is a spooky and magical number, right?)

With this expansion, the game of Tzolk'in: The Mayan Calendar is also based on three prophecies that are revealed ahead of time and fulfilled when the time is right. These prophecies give players other chances to score points, but they can also lose points if they don't prepare themselves for the prophecy effects. As with the tribes, the expansion has 13 prophecies. (Woohoo, 13 again!)

This expansion also has new buildings and components that offers up to 5 players to compete.
