A stunningly beautiful game about making art from algae

Hidden in the water all around us are tiny lifeforms known as “diatoms.” These microscopic algae cells come in a variety of exquisite geometric shapes and patterns. Here at the Society for the Microscopic Arts, we collect these diatoms and delicately arrange them on slides into beautiful, tiny mosaics.

Diatoms is a puzzly tile-placement, pattern-making game where you create a microscopic mosaic out of single-cell algae. Take turns placing tiles representing algae colonies, earning diatoms of different colors and shapes. Then thoughtfully 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!

Plus: Play solo or collaboratively with Diatoms Commissions! Free, In the box!
In Commissions,  you’ll be creating beautiful mosaic designs to order based commissioned requests. This is a single-player game that can also be played together as a collaborative game.  Commissions is a unique, meditative game experience with 36 different mosaics to try!

Diatom mosaics are a real thing, though this artform has only ever been practiced by a vanishingly small number of people. Diatoms themselves are also a pretty big deal as they produce up to 50% of the oxygen we breathe.
