Printable Sudoku

Free printable Sudoku puzzles, made in your browser the moment you ask for them. Pick a level, pick how many fit on a page, and print — no sign-up, no PDF download, and no watermark across the middle of the grid.

How to print them

Choose your options above and press Print. The site's header, footer and everything else on this page drop away automatically — the printed sheet carries the grids and nothing else, so you are not spending ink on navigation.

If your browser adds its own header and footer with the page URL and date, turn off "Headers and footers" in the print dialog's options. Portrait orientation and any normal margin setting will fit the grids comfortably.

Smaller grids for children

The Grid size menu also prints 4×4 and 6×6 puzzles — the same small boards as the Sudoku for kids page, on paper. A 4×4 uses the digits 1 to 4 and a 6×6 uses 1 to 6, so a child can finish one without needing to scan a nine-wide row. Those two sizes have one setting each rather than four levels, which is why the difficulty menu greys out when you pick them.

Six 4×4 grids to a page is a sensible classroom sheet; for a 6×6, four to a page keeps the squares big enough for a young hand to write in.

Choosing a level

The clue count printed under each grid tells you roughly what you are in for, and the four levels here mean the same as they do on the playable boards:

• Easy — around 42 clues, solvable by scanning alone. The right choice for children, for a beginner, or for a puzzle on a coffee break.
• Medium — around 34 clues. Scanning runs out and you will need hidden singles.
• Hard — around 28 clues, wanting pencil marks and pairs.
• Expert — around 24 clues. Bring a sharp pencil.

Printing four or six to a page shrinks the grids, which matters more than it sounds: hard and expert puzzles need room for pencil marks in every square. For those two levels, one or two per page is the practical choice.

Every sheet is different

These are generated when you ask for them, not picked from a fixed library, so pressing New puzzles gives you a set nobody else has. Each grid is checked for a unique solution before it is shown — the same guarantee the on-screen game makes — so a printed puzzle never dead-ends and never needs a guess.

Prefer to solve on a screen, with notes, undo and a timer? Play easy, medium, hard or expert instead. New to Sudoku? Start with how to play, then come back and print a few once the rules have stuck.
