Game Summary:
Diatoms is a puzzly tile-placement, pattern-making game where you create microscopic mosaics out of single-cell algae. Vie with your fellow players to collect diatoms for your mosaic:  take turns placing tiles representing algae colonies, earning diatoms of different colors and shapes, then strategically place these diatoms on your own mosaic, taking care to consider how your arrangement will be scored by the judges at the end of the game. Everyone will create a unique mosaic, but only one player will win first place for their microscopic art.
