Free Printable Sudoku

Make your own printable Sudoku in seconds — pick the difficulty and layout, then print the sheet or save it as a PDF. Every puzzle has one guaranteed solution, and an answer key is one click away.

How to print your Sudoku

Set the options above — difficulty, how many puzzles per page, how many pages, and your paper size — then press Print / Save as PDF. In the print dialog choose your printer to print on paper, or pick "Save as PDF" as the destination to download a file you can print later or share. Only the puzzle sheets print; the controls and this page text are left out automatically. Press New puzzles any time for a fresh set.

Great for classrooms, travel and screen breaks

Printable Sudoku is perfect when you would rather hold a pencil than stare at a screen — for the classroom, road trips, waiting rooms, care homes, or a quiet coffee break. Teachers can print a page of four easy puzzles for a warm-up; puzzle fans can run off a stack of expert grids for the week. Because everything is generated in your browser, you can make unlimited unique sheets without signing up for anything.

Choose exactly what you print

You control the whole sheet: difficulty from easy to expert, 1, 2, 4 or 6 puzzles per page, up to four pages at once, Letter or A4 paper, and whether to add an answer key on a separate page at the end. Prefer to play on screen instead? Try the classic board, the daily puzzle, or variants like Killer and Color Sudoku. Making them for young children? Try 4×4 shape puzzles on Sudoku for Kids.

Why printable Sudoku is still popular

Even with a good game a tap away, plenty of solvers still prefer paper, and for good reasons. A printed grid never pings with a notification, never needs a charger, and leaves your hands free to jot candidates in the margins the way you like. A page of puzzles is easy to share around a table, slip into a bag for a journey, or hand to someone who would rather not use a screen at all. And a stack of sheets is a simple, low-cost resource for a classroom, a care home or a club — print once and you have a week of puzzles ready to go.

Tips for a clean printout

A few small choices make the sheets nicer to solve. Four puzzles per page is the sweet spot for most people: the grids stay large enough to write in comfortably without wasting paper. If you are printing for young children or anyone who finds small cells fiddly, drop to one or two per page for roomier squares. Turn the answer key off when you want to hand out puzzles without the temptation of a nearby solution, and on when you are checking work together. Finally, match the paper size to your printer — Letter in North America, A4 almost everywhere else — so nothing is clipped at the edges.

Fair, guess-free puzzles

Every printable puzzle is built with a single, unique solution and checked by a solver before it reaches the page, so you never have to guess — logic alone will always finish the grid. That is the same promise behind every game on Sudoku AZ.
