How to print (A4/US Letter) for best results
Open the PDF and select Actual Size (100%) in your print dialog.
Choose A4 (210×297 mm) or US Letter (8.5×11 in) to match your paper.
For maximum clarity, use normal print quality; for ink savings, choose draft.
If borders appear, disable “Fit to page” our free Sudoku printable PDFs are already sized correctly.
Tips to solve faster (for all levels)
Scan for singles: Fill any cell with only one possible number.
Use pencil marks: Note candidates lightly; erase as you eliminate options.
Check rows, columns, boxes: If a number is missing from a 3×3 box, see where it can legally go.
Look for pairs/triples: Naked or hidden pairs reduce candidates quickly.
Stay systematic: Work one region at a time to avoid missed deductions.
