Five in a row,
evolved.

Pass the device. Take turns placing X and O on an endless field. Make five in a row — horizontal, vertical, diagonal — and your win seals into a wobbly little amoeba you can come back to forever.

Amoeba running on iPhone — four amoebas on the field with an active round in progress

What makes it different

A tiny ruleset, an organic memory of every game you've played.

Hot-seat, no setup

Hand the device back and forth. No accounts, no servers, no ads, no network. Just two humans and a board.

Endless field

Pinch to dive in, pull back to take it all in. The board doesn't end — every won round leaves an amoeba and the next round starts somewhere fresh.

Organic trophies

A winning row seals into a metaball blob colored by the winner. Build a menagerie of amoebas across an infinite field.

iPhone, iPad, Apple TV

Same game across iPhone, iPad, and Apple TV. Touch and pinch on iOS; touchpad cursor + Select to place on tvOS.

How a round plays

1

Drop a stone

Tap a cell. X plays first, then O. Every new stone has to touch an existing one in the round, so the amoeba grows as one organism.
2

Make five in a row

Connect five stones in any direction. Block, double-threat, sacrifice — the rules are tiny, the strategy is not.
3

Seal the amoeba

The winning row freezes into a wobbly organic shape tinted by the winner. A new round opens somewhere fresh on the field.
