Sudoku PDF Booklet — Free Download
Pick a difficulty and how many puzzles you want. Download a single PDF with a title page, the puzzles, and an optional solutions appendix.
The download starts as soon as the PDF finishes generating. Larger booklets (16 or 32 puzzles) take a few seconds.
Why a fresh sudoku booklet beats a static PDF
Most printable sudoku PDFs you find online are static files: the same 100 puzzles every time, reused across thousands of downloads. A new puzzle book on Amazon costs five to ten times what the paper itself is worth. Both options miss the point — sudoku is a generator-friendly game, and the right way to get a fresh book is to generate one on demand.
This page does exactly that. Pick a difficulty (anything from Easy to Evil), pick how many puzzles you want (4 for a sitting, 8 for a week, 16 for a trip, 32 for a binder), and the generator builds a multi-page PDF on the spot. Every puzzle is freshly generated, mathematically verified solvable without guessing, and you can run it again tomorrow for a completely different book.
What's inside the PDF
Title page with the difficulty and puzzle count, so the booklet feels like a real book when you hand it to someone.
One full-page puzzle per page, large enough to read and write on comfortably. Each puzzle has a unique ID stamped in the header — if you want to come back to it online, you can search by that ID.
Optional solutions appendix at the end. Four solutions per page, smaller grids, with the ID labels matching the original puzzles. Skip it if you'd rather check yourself.
Good fits for the booklet format
Travel. A 16-puzzle PDF on your phone or printed at home covers a week of flights, hotels, and coffee shops without depending on signal.
Gifts. Print a 32-puzzle booklet, fold a card-stock cover, write a name on the front. Costs nothing beyond paper and works for anyone who likes a puzzle book.
Classrooms and after-school programmes. One PDF download covers a half-term of warm-up activities at the difficulty you've already calibrated to your class.
Practice packs. If you're working through a specific difficulty (say, expert) to get faster, 32 fresh expert puzzles in a single download saves you regenerating one-by-one.
Frequently asked questions
Quick answers about printing sudoku from Sudoku247Online.
- How does this compare to a $10 sudoku book?
- Same content density, completely free, freshly generated each time you download. The only thing a paper book has that this doesn't is a glossy cover.
- How long does the PDF take to generate?
- Fewer than 2 seconds for a 4-puzzle booklet, around 5 seconds for 32 puzzles. The download starts automatically once it's ready.
- Can I generate the same booklet twice?
- Each click of "Generate" produces a completely fresh set of puzzles. If you want to share a specific booklet with a friend, just share the downloaded PDF — there's no way to re-derive identical puzzles from the same URL.
- Are the solutions in the same PDF or a separate file?
- Same PDF — they sit in a clearly-labelled "Solutions" appendix at the end. Toggle them off if you'd rather work without an easy answer at hand.
- What size is the PDF?
- A 4-puzzle booklet is roughly 30 KB. A 32-puzzle booklet with solutions is roughly 200 KB. Trivial compared to a photo.
- Can I print on Letter-sized paper?
- The PDF is generated at A4 (210 × 297 mm). Most printers scale A4 to Letter automatically. If you specifically need Letter dimensions in the source file, that's a planned follow-up — for now the on-screen print hub at /print supports both paper sizes for single-puzzle prints.
