A round of Mitosis: a pink player cell among food, rival cells and green phages, with the round clock and leaderboard

How a round works

Ten minutes. One dish. Last cell wins.

Every round starts with the whole dish open. Grow, hunt and survive while the safe zone shrinks toward the centre.

Absorb

Eat food and anything smaller than you to grow. Bigger cells are slower, so size is power and a target at once.

Divide to strike

Split to launch half your mass at a cell in reach, shoot mass to bait or feed, and boost out of trouble.

Outlast the dish

The arena closes in and anything outside dissolves. When only one player's cells are left, the round is theirs.

What's in the dish

More than eat or be eaten

A living world that changes every round, a rating that means something, and skins worth showing off.

A rating that means something

Survive, absorb and place high to climb the ranked ladder. Every round shows your placement and how your rating moved.

Evolve as you grow

At mass milestones your cell mutates: faster flagella, a tougher membrane, digestive enzymes and more. Read a rival's traits before you commit.

A living world

Nutrient blooms, antibiotic tides, phage swarms and the Leviathan. The leader wears a crown and pays a bounty to whoever takes it.

Skins worth showing off

Earn ATP by playing and spend it in the shop on hand-drawn premium skins. Everyone in the round sees what you wear.

Play with friends

Add friends with a code, form a party and drop into the same arena. Allies can't eat each other.

Fair and quiet

No ads, no chat, no tracking. Bots fill empty slots so you never wait, and practice against bots works offline.
