Marine microbes form the basis of life in the ocean and perform 50% of earth’s photosynthesis. But they live extraordinary lives of their own; fraught with danger and opportunity. Oligotrophic is a fast-to-learn, strategic tile placement game where players compete to place biomass the fastest. In the game players will select and play hexagonal cards based on actual microorganisms to accumulate biomass, often getting bonuses, hurting, or taking biomass from the other organisms they encounter. Oligotrophic is fully available online in both full color and print friendly versions in the files section. All that is needed is 20 cubes of a color for each player. —description from the designer
