In Tekhenu: Obelisk of the Sun, players take on the roles of nobles in Ancient Egypt as they build both the Temple of Amun-Ra and the area that is to become Ipet-Isut.
On their turn, they will choose a die that is at the base of the Obelisk; they can choose to perform a specific god's action based on the die's location around the Obelisk, produce recources based on the die's color, or alter the die/action with a Scribe.
As the Obelisk's shadow changes position, different die colors will be become Pure, Tainted, or Forbidden, changing how the die will sit on the player's scales when the times comes for Maat's judgement.
There are 4 Maat phases and 2 Scoring phases during the course of the game. While Maat phases only take into player order (and any points lost due to excess Taint), Scoring phases will require that they pay for the buildings they have built and provide Victory Points for the various god actions they have taken.
