Pass the device. Take turns placing X and O on an endless field. Make five in a row — horizontal, vertical, or diagonal — and the win seals into a little metaball-style amoeba, tinted by whoever won it, that stays on the board forever.
- Hot-seat, no setup — 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 behind and the next round starts somewhere fresh.
- Organic trophies — a winning row freezes into an organic blob colored by the winner, building a menagerie of amoebas across an infinite field over time.
- Same game everywhere — iPhone, iPad, and Apple TV. Touch and pinch on iOS; touchpad cursor and Select to place on tvOS.
The ruleset is tiny; the strategy — blocking, double-threats, sacrifice — is not. No accounts, no ads, no network calls: scores and amoebas live only on the device.
