How to get the most from our printable Sudoku puzzles
Printing tips
- Use standard 80 gsm paper — regular printer paper works perfectly. No special paper needed.
- Print in black & white — all grids are designed for mono printing, so greyscale mode saves ink without affecting readability.
- Set scaling to "Actual size" or 100% — this prevents the grid from being cut off or shrunk. Avoid "Fit to page."
- Set margins to None or Minimum — especially important for A4 grids on borderless-capable printers.
- Print one puzzle at a time — each PDF is a multi-page pack. Enter a single page number in your print dialog to save paper.
- Download and print later — save the PDF to your device to print offline anytime, anywhere.
Choosing the right difficulty for your session
- New to Sudoku or returning after a break? Start with Easy. Most cells fill using simple naked-single logic — no pencil marks needed. Good for commutes and wind-downs.
- Comfortable with Easy, want a longer solve? Move to Medium — expect 20–35 minutes using hidden-single logic and pencil marks.
- Looking for a real challenge? Hard requires full candidate tracking and multi-step eliminations.
- Experienced solver? Expert and Master push advanced techniques like Swordfish and XY-Wing.
- Not sure which level fits you? Try today's free online Sudoku in your browser — all five levels, with optional hints.
