Where to start
Look at row 4, column 2: only one number fits there.
The rules
Every row and every column contains 1 to 9. Instead of 3×3 boxes there are nine regions with thick borders: each of them also contains 1 to 9.
Tips for solving it
- Trace the region borders with your pencil: seeing them clearly is half the work.
- Count cells: regions that stick into a row or column tell you which numbers are left for the other cells.
- A long, narrow region touches many rows: its numbers fall into place early.
- Remember that rows and columns still work as in the classic: do not forget them while looking at the shapes.
