Fillomino
Grow orthogonally connected regions until each region contains exactly the number written in its cells.
How to Play
Each number belongs to a region whose area must match that number. Grow and merge regions until every filled cell belongs to a valid orthogonally connected group.
- Every region must be orthogonally connected.
- A region's area must equal the number written in its cells.
- Regions with the same number may not touch orthogonally.
- Given cells are fixed and cannot be changed.
