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.
Free to print and copy for home, classroom and library use. Every puzzle has one answer you can reach by logic alone.
