How to solve
- Count the block: A number counts the filled cells in its 3x3 block, itself included.
- Fill or leave blank: Every cell ends up either filled or empty.
- Edges count less: Blocks on the edge have 6 cells and corner blocks have 4.
- Use the overlaps: Neighbouring numbers share cells, and comparing them is where most deductions come from.
