Petri Dish

A zen-like game where you play as a biological cell in a petri dish viewed through a microscope. Tap to move via chemotaxis, engulf nutrients, grow, and divide. Every mechanic is inspired by real biology — from phagocytosis and mitosis to quorum sensing and bacteriophage infection. Start as a single cell. Attract nutrients with a tap. Grow large enough to divide and build a colony. Navigate an ecosystem of bacteria, diatoms, viruses, predators, and more — each generation introduces new biological challenges. Features: • Soft-body cell physics with realistic membrane deformation • 20+ generations of escalating biological challenges • Real organisms: bacteria, diatoms, paramecia, rotifers, tardigrades, slime molds • Light and dark-field microscopy modes • Procedural ambient soundscape • No ads, no in-app purchases, no data collection
