It's said that Wiraqocha created the sun and the pre-Columbian tribes of the Andes. Under his leadership, those who'll train the mighty Inca people came out of their caves to discover new horizons in order to subsist and grow in harmony with nature. They respect Pachamama, Mother Earth, the basis of all living things, plants and minerals, on earth and under the earth.

In Tiwanaku, first announced as Pachamama, you will lead your tribe into unknown territory in search of new lands to cultivate. Your aim: To explore regions and draw outlines to create cultures according to the customs and legacies of Pachamama. If you honor Her by respecting the great principles of diversity and complementarity, Nature will reward you; otherwise, you'll suffer his wrath. In this race, risk-taking, deduction, intuition, and a good sense of timing should allow you to get through.

Every scenario disc indicates a unique arrangement of terrain tiles and crop tiles. Terrain tiles are in regions of up to5 spaces, and a region of one color does not touch a region of the same color, even diagonally. Crop tokens have a value of up to 5, and each value has a different size/color (level 1 is brown, level 2 is green, etc.). A size 1 region will contain a value 1 crop token, a size 2 region will contain crop tokens of value 1 and 2, and only a size 5 region will contain crop tokens of each value. Two identical crop values can never be adjacent, even diagonally.

On a turn, take either an explore action or a divine action: At the end of an explore or divine action, you can hand in up to 5 offering cubes for 0-10 points. You may hold at most one offering of each color.

When the final terrain tile is put on the game board, the end of the game is triggered. Beginning with this player, each player in turn can take a single divine action or pass. If you pass, you will take no further actions. If you divine, you get points and an offering cube like normal, or you lose points and must pass. Keep taking turns around the table until everyone has passed, then make a final offering and see who has the most points.
