Oros is a tile-colliding, volcano erupting, mountain-making, wisdom-gathering, action-economy strategy game. On individual player mats, players move their Followers between action spaces, allowing them to manipulate a shared environment like a giant puzzle of plate tectonics. Action spaces allow players to shift rows of land, move and collide land tiles, form and erupt volcanoes, worship to gain wisdom, journey their Followers around the ever-shifting landscape, and build sacred places of study and worship on mountains. Building sacred places and worshipping in sacred places brings wisdom which is used to improve the abilities available for each action space. Wisdom is also used to improve the end game value of each sacred place built as well as reach other goals worth end game points.
When building sacred places, the Demigods of the Wise One ascend a ziggurat which acts as a timer toward the end of the game. When one reaches the top, players finish the round and then tally a final score.
