Fillup

Small moves. Big chain reactions.

Fillup is a turn-based strategy game where you place slices, build up your cells, and trigger reactions that capture neighbouring cells. The goal is simple: capture every enemy cell. Finding the right move is where the strategy begins.

Start with a guided tutorial, take on bots in Campaign, or challenge other players online. A well-timed reaction can turn a losing position into a comeback.

Play free in your browser—no download required. You can start as a guest and link an email address to keep access to your progress across browsers and devices.

Fillup is in active development, and your feedback will help shape it.

You don’t need to be a strategy-game expert. First impressions are especially useful.
