Fathom is a tile-laying game where players compete as marine biology teams exploring an uncharted underwater ecosystem. Over six rounds of simultaneous play, guide your boat and submersible to scan the depths, place tiles and discover marine creatures.
Score points based on how well the discovered species align with their preferred habitats – some flourish in uniform environments, others need diversity, and certain creatures thrive alone while some require groups.
Create the most harmonious ecosystem to win!
