Four free browser games set in a shared cell universe. Nothing to install, no account to create — every game runs entirely in your browser and saves progress locally. Below they are grouped by genre, with the controls, typical session length and difficulty for each.
Fast games you can pick up for one minute or push for a high score.
A cell that escaped the petri dish falls into the bloodstream and the current drags it forward. The vessel splits into three lanes: switch lanes to dodge blood clots and viruses, jump over rolling red blood cells, and duck under fibrin bridges. Your score is the distance you survive. At least one lane is always clear, so every wall of obstacles can be solved if you read it early enough.
A bullet-hell survival game about weaving a single cell through waves of projectiles. Waves escalate into multi-phase boss encounters, and between runs you spend what you collected on an upgrade tree that changes how the next attempt plays. There is also a daily challenge seeded from the date, so every player gets the same layout on the same day.
Slower games about observation and timing rather than reflexes.
A hide-and-seek game where your cell disguises itself as ordinary lab equipment to evade an AI inspector sweeping the room. Hold still and you blend in; move at the wrong moment and suspicion builds until you are found. The tension comes from deciding when the inspector's back is turned long enough to reposition — mimicry as a survival strategy, which is a real thing cells do.
Games that keep making progress while you do something else.
A petri dish that grows on its own. Click to add biomass by hand at the start, then unlock cell types that produce for you, manage the culture medium they consume, and watch the rate compound. Eight cell types unlock in sequence, each with its own behaviour — the progression loosely follows how a real culture is grown and maintained.
The games are loosely connected. The cell you grow in Cell Culture is the one that escapes the dish and has to hide from the inspector in Cell Mimic; the same escapee later falls into the bloodstream in Cell Rush. You can play them in any order, but that is the intended reading. If you want the biology behind the games rather than the games themselves, the articles section explains what real cells do and where each game takes liberties.
