Set up your page
Choose a level, layout and number of grids. The suggested values show a readable example before your first print.
Example ready: four easy grids are shown.
2 · CHECK
A4 page preview
Check the cell size and spacing before printing. Given digits are darker, while empty cells stay large enough for pencil notes.

WHY PRINT
A simple paper sudoku to prepare
Printable sudoku is useful when you want to solve away from a screen, share an activity with a child or keep a puzzle in a travel bag. This generator puts the settings, preview and print action in one short workflow. There is no account, app installation or hunt for a separate PDF file.
The page creates classic 9 x 9 grids. Each example starts from a valid complete solution and removes values according to the selected level. The printed design stays deliberately quiet: firm borders, even cells and readable type, even when six exercises share one sheet. Paper gives you room to pencil candidates, circle a pair or record a deduction.
Use the tool for a five-minute warm-up or a longer worksheet. Pick Easy to learn the rhythm, Medium for daily practice, Hard to review pairs and locked candidates, or Expert for a slower challenge. Mixed levels alternate the four forces to make a varied small set.
HOW TO USE IT
Create a printable sudoku in four steps
The preview uses the same settings as the printed sheet. Take a moment to check page density and level before opening the print dialog.
Choose a difficulty
Open the Level menu and select Easy, Medium, Hard, Expert or Mixed. The level changes how many clues are already visible and how many deductions are needed.
Choose a layout
Four grids are a comfortable balance for writing. Six grids are handy for travel or a short session; one large grid leaves more room for candidates.
Decide on answers
Keep the option on when you are preparing a worksheet with a key. Turn it off for a clean challenge, then check the preview to make sure the page stays open.
Generate and print
Click Generate grids, inspect the result and choose Print now. In the browser dialog, select A4 and confirm the preview before printing.
PICK THE RIGHT CHALLENGE
Which printable sudoku level should you choose?
Difficulty is not only the number of empty cells. It describes how many logical crossings you may need before the next placement. Use this table as a starting point and adjust it to the time you have.
| Level | Good for | Suggested approach |
|---|---|---|
| EasyForce 1 | Beginners, children and a gentle restart | Look first for rows, columns and boxes with one possible cell. |
| MediumForce 2 | Regular players who want a 10–20 minute game | Write candidates and compare missing digits inside one unit. |
| HardForce 3 | Players comfortable with pairs and eliminations | Work with naked pairs, locked candidates and box-line intersections. |
| ExpertForce 4 | Fans who enjoy studying one grid for longer | Keep your pencil light and search for patterns before guessing. |
PAPER AND READABILITY
Four, six or one grid: which layout works best?
Four grids per page is the versatile setting. Cells remain large enough for pencil candidates and the page works as a small practice sheet. It fits most home printers and leaves breathing room between exercises.
Six grids favor quantity. They are useful when you want several games ready for a trip, a classroom activity or a screen-free break. For a Hard puzzle, consider printing four instead if you expect to write many notes; readability matters more than the raw number of puzzles.
One large grid per page suits people who write larger, older players or an Expert puzzle that needs many candidates. In every case, treat the system preview as the final reference because printer margins and scaling can vary.
- A4 portrait is the simplest format for a home printer.
- Economy mode keeps the 3 x 3 separators while using thinner lines.
- Matte white paper makes pencil notes easier to read and avoids glare.
- Print one test page first when sharing a longer series.
CHECK WITHOUT SEARCHING
Show solutions or keep them separate
Answers are optional. When the checkbox is active, each puzzle receives a solution line after the exercise. This is useful for a workshop, a family activity or anyone who wants to check a deduction without opening another tab.
For a class handout, a family challenge or a timed session, turn the option off before generating. The preview and the printed sheet use the same state, so a response will not appear by surprise. You can always create a second answer sheet after the session.
A solution shows the final result but does not replace the reasoning. If you are stuck, return to the row, column and box with the fewest empty cells. Then use candidates to understand why a digit fits rather than copying an entire line.
Tip: for a shared worksheet, print one clean version and keep a second answer page for the person leading the activity.
SOLVE MORE COMFORTABLY
A calm method for every paper grid
On paper, begin by scanning the nine 3 x 3 boxes. Notice common digits and write a small candidate only when the cell is genuinely open. This broad scan prevents guesses and makes the intersection between a row and a box easier to see.
When a puzzle slows down, use a fine pencil and erase eliminated candidates cleanly. A naked pair, such as two cells that can only contain 2 and 8, lets you remove 2 and 8 from the other cells in that row, column or box.
Track your time if you want to improve. Compare puzzles at the same level, then move up when you can explain your placements. The point of a printed sheet is to make the reasoning visible, not to finish at any cost.
- Use a pencil so an assumption can be corrected without damaging the grid.
- After each placement, check the affected row, column and box.
- Take a short pause if you keep repeating the same scan.
- Use a separate scrap sheet for calculations when you choose a large grid.
- Sort printed pages by level so the next session is easy to choose.
BEFORE YOU PRINT
Practical limits and local data
This generator prepares a page; it is not a professional print service. Exact sizing depends on your browser, margins and printer driver. Always inspect the system preview before confirming, especially with six grids or automatic scaling.
Grids are generated in your browser. The site does not store your level, the puzzles you create or their solutions. If you refresh before printing, click Generate grids again to make a fresh set.
To keep a collection, use your browser’s Print to PDF option. The file is created on your device by the print system; the generator does not provide an external download link or ask for an email address.
- The deliberate limit is six grids per generation so the page stays readable.
- A printed grid cannot resize itself after the print dialog opens.
- Economy mode changes visual spacing, not the digits or solution.
- The tool is for classic 9 x 9 sudoku, not irregular-region variants.
FREQUENT QUESTIONS
Questions about printable sudoku
Can I print a sudoku for free?
Yes. Choose your settings, click Generate grids and then Print now. The browser opens its print preview without an account, payment or extra software.
Which layout is easiest to read?
Four grids per page is the best balance for pencil notes. One large grid gives more room, while six grids are useful for a compact set.
How do I make a sheet without answers?
Turn off Show solutions after the puzzles before generating. The preview updates immediately and no answer line is printed.
Is Easy suitable for children?
Yes. Easy is a friendly way to learn the three sudoku rules. For a first attempt, choose four grids and keep a pencil and eraser nearby.
Are my grids uploaded?
No. Generation, shuffling and solution checking happen locally in JavaScript. Only your device’s print dialog is used afterward.
Can I save the page as a PDF?
Yes. Select Save as PDF or Microsoft Print to PDF in the print dialog, then check A4 and the margins before saving.
Keep playing online
After a paper sheet, return to the interactive board to resume a puzzle, change level or use notes and the timer. The two formats complement each other: paper slows the reasoning down, while the online board makes trials easy.
