How to Play

The world of Voromoeba is a series of circular ponds. You are a voromoeba, a single-celled creature who lives in a pond. Your dear sweetie is trapped in a frozen pond, and can only be saved by a kiss from you. You must venture forth through the ponds to reach your sweetie! Along the way, you must elude or destroy predators and gather food.

It's an ordinary life for an adventurous fairy-tale protozoan, with a twist: The ponds are Voronoi diagrams. Each thing in the pond is Voronoi cell. The rules behind Voronoi diagrams make the boundaries between cells fluid. Even if you do not follow the math, by playing the game you will get an intuition about how the boundaries behave.

Note two properties:

• • Voronoi cells are always convex.

  • The boundary between two adjacent cells is equidistant from their seeds, and perpendicular to a conceptual line segment between those seeds.

In the game, the g key toggles display of the seeds. Displaying the seeds may help you gain intuition for Voronoi diagrams. Seed display is disabled when your score reaches 20, on the assumption that you learned enough.

The Voromoeba manual gives more details.
