Why this one
Most printable sudoku sites hand you the same recycled PDFs, ask you to make an account, or print their logo across the middle of the page. Here the puzzles are generated in your browser the moment you ask for them, so the batch you print is genuinely new, and pressing Print gives you the sheet exactly as you see it — no download, no watermark.
The one-per-page option exists because a lot of these sheets end up in care homes and classrooms, where a grid squeezed four to a page is unusable. One per page gives big squares and thick lines with room to pencil in candidates. And every puzzle is verified to have a single solution before it reaches the paper, which is not something a scanned PDF can promise.
Frequently asked questions
Do I get a PDF?
No, and you do not need one. The puzzles print straight from your browser — and if you do want a file, use your browser’s “Save as PDF” option in the print dialog.
Are the puzzles always solvable?
Yes. Each grid is built by removing numbers only while exactly one solution remains, so every puzzle has a single answer you can reach by logic alone — no guessing.
Can I print large print sudoku?
Yes — choose one puzzle per page. You get a big grid with thick box lines and space to pencil in candidates, which is what most large print sheets are actually for.
Can I print the answers?
Yes. The answer key prints after the puzzles, packed several to a page, with the numbers you have to work out shown in grey. Untick the box if you would rather not have it.
Can I use these in a classroom or care home?
Yes — make and print as many as you like, free, no account. The small credit line at the bottom can be turned off with a checkbox.
