Ever thought about turning microscopic biology into a Victorian masterpiece? In Diatoms, you step into the shoes of an artist from the 'Society for the Microscopic Arts,' where the goal is to create stunning mosaics using diatoms—those microscopic algae with silica shells that look like geometric jewels under a microscope. The game is an exercise in elegance and spatial strategy, blending the satisfaction of solving a puzzle with the competitiveness of a modern board game.

The gameplay unfolds in two main stages: first, you place tiles representing algae colonies on the board. This action serves as your 'resource engine,' as it's how you collect diatoms of various colors and shapes. Then comes the more cerebral part: arranging these pieces on your personal board. Here, every move matters. You must plan your layout to maximize scoring, aiming for matching colors, a variety of shapes, and, most importantly, perfect symmetry along your mosaic's central lines.

To keep the experience fresh, the game introduces 'guest judge' cards. Each judge brings a unique scoring criterion, shifting the optimal strategy from game to game and forcing you to adapt your artistic vision. For those who prefer solitude, Diatoms offers a robust solo variant where the goal is to fulfill specific mosaic commission prompts, turning the experience into a pure optimization challenge. It's the kind of game that is visually mesmerizing and mentally stimulating, perfect for players who love abstract games that still offer a fascinating and sophisticated theme.
