Fillomino
Fill the board so that each orthogonally connected region contains exactly as many cells as its number.
Rules
- Every numbered region must be orthogonally connected.
- The size of each region must equal the number written in its cells.
- Regions with the same number may exist multiple times, but they cannot touch orthogonally.
- Given cells are locked. The puzzle is solved when every cell is filled and every region is valid.

Tips
- Start from givens that force a small region, like
1,2, or3. - If a connected group already has its full size, every orthogonal neighbour must belong to another region.
- If a group cannot possibly grow to its required size, something inside or next to it is wrong.
