In Fillomino you divide the board into regions and write a number in every cell. The rule is simple but powerful: each connected region must contain exactly as many cells as the number written in it — a 3 belongs to a region of three cells — and two regions of the same size may not sit next to each other.
The rules
- Fill in numbers so each connected region has as many cells as the number it holds.
- Two regions of the same size may not share an edge.
- Pick a number and drag across cells to fill a whole region in one go — or tap them one by one.
Getting started: With two neighbouring regions of four empty cells each, none can be 1–3 (wrong size or equal neighbours) — so they must be 4.
