One slice can turn the whole game around.

Fillup is a turn-based strategy game where small moves build into board-changing chain reactions. Place slices, fill cells, and send pieces bursting into neighboring territory. Capture an opponent’s cells at the right moment and watch one reaction trigger the next.

Set around a warm, illustrated tabletop, it’s a game of careful positioning, risky setups, and sudden comebacks.

How to play

Place a slice in an empty cell or one you already own. When a cell fills, it bursts into its connected neighbors, capturing them in your color. Those cells can burst too, setting off a chain reaction across the board.

In elimination matches, your goal is to remove every opponent from the board. Campaign challenges add different objectives to test your strategy.
