Diatoms is a puzzly tile-placement and pattern-making game where you create your own microscopic mosaic of beautiful shimmery algae, based on an obscure Victorian art form.

Step into the world of Victorian naturalists, where microscopes revealed the unseen natural world. Collect and arrange glittering diatoms into mosaics that shine under your “microscope." Compete to impress the judges of the Society of Microscopic Arts, or advance your career as a diatomaceous artist by completing solo mosaic commissions.
