Printable Sudoku — Free PDF Puzzles

Loading puzzle

Every Sudoku on this page can be downloaded as a printable PDF. Choose a level from 1 to 100 and a board size from 4×4 to 16×16, play online as long as you like, then press Download PDF to save the exact board — including any digits you have already entered — as a clean, printer-ready A4 page.

Unlike static pages of pre-made grids, every puzzle here is freshly generated and uniqueness-checked, so there is always a new board to print. Your own entries print in blue, distinct from the black given clues, which makes the PDF a natural way to start a puzzle on screen and finish it on paper.

Downloading takes a free account — that is what lets us tie each export to your own board and guarantee it never spoils the answer. A solution sheet is added only after you have solved the puzzle and checked it online.

How to print a Sudoku PDF

Pick a board size in the panel beside the board — 4×4 or 6×6 for kids and beginners, the classic 9×9, or 12×12 and 16×16 for a long solve.

Pick a level. Levels 1–10 teach the basics on gentle boards; levels 11–100 climb steadily toward expert.

Play as much or as little as you like — the PDF captures the board exactly as it stands, so you can start on screen and finish on paper.

Press Download PDF under the board. If you are not signed in yet, you will be asked to create a free account first.

Open the file and print it. Each puzzle fills an A4 portrait page with bold grid lines and a header naming the puzzle, level, and size.

Why print your Sudoku?

Paper is still the nicest way to solve for many people: no screen glare, no battery, and pencil marks exactly where you want them. A folder of downloaded PDFs is a puzzle book you assembled yourself, at exactly the difficulty you enjoy.

Teachers and activity organisers print the small 4×4 and 6×6 boards for classrooms and group sessions, while regular solvers tend to print 9×9 boards between levels 20 and 60. If a printed puzzle turns out too hard, the same board is still waiting on your account online — with pencil marks, feedback, and hint explanations to get you unstuck.

Printable Sudoku FAQ

Is the printable Sudoku PDF free?

Yes. Creating an account is free, and every puzzle, level, and PDF download is included in the free plan. Premium adds a live AI coach and ad-free play — printing is never paywalled.

Does the PDF include the solution?

Not while you are still solving. The download contains only the board — givens in black, your entries in blue. Once you have completed the puzzle and checked it online, the export adds a separate solution sheet.

What paper size does the PDF use?

One board per A4 portrait page; it also prints cleanly on US Letter. The header names the puzzle, its level, and its size, so a stack of printouts stays easy to sort.
