What Is Mitosis?

Diagram of Mitosis gameplay where a large red cell splits into smaller cells, each labeled with the cash value it is worth.

Mitosis is a Roblox incremental simulator from Fauna Studio in which players build up their cells through repeated splitting and upgrades. Rebirth progression and leaderboards give that cycle longer-term goals.

    The × counter above SPLIT shows the batch size

  2. Press SELL to turn the batch into Cash

    One cell is left behind so production continues

The Cash Loop

How split, sell and upgrade feed each other, and when to time a sale.

View full page
Repeatable gameplay cycle

  1. Split

    SPLIT multiplies your cell population; the × counter above it shows the batch size.

  2. Sell

    SELL converts the batch into Cash — 2× during Gold Rush, 1.5× during Rainbow.

  3. Upgrade

    Spend Cash on upgrades like Ball Value and Split Speed to improve the next batch.

Upgrades make every later split worth more, so the loop repeats stronger.
