Players move Followers on individual mats to manipulate the environment in a unique giant puzzle of plate tectonics. Action spaces shift land, collide tiles, erupt volcanoes, worship for wisdom, journey across the ever-changing landscape, and build sacred places of study and worship on mountains. Building sacred places and worshipping brings wisdom to improve action abilities and end game points.

At the core of Oros is the unique ability to shift, move, build up, erupt, and reposition the land within an infinitely connected play environment. This mechanic turns every action into a puzzle of creative problem solving, abstract thinking, and a constantly evolving strategy. Another chief aspect of the game is the player mat which uses a minimal worker placement mechanic to govern action opportunity. The mat also maintains an action economy that evolves differently for each player as they invest their gained wisdom into a variety of action improvements. Because of these core aspects, there are dozens of strategies for players to explore, and every game plays out in a different, yet competitive way.
