Which level is right for you?

Beginner needs naked singles only: there is always a square with just one possible number. The place to start, for adults and children alike.
Easy adds hidden singles: the one square in a row, column or box where a number fits. No pencil marks needed.
Medium needs naked pairs and pointing pairs, so pencil marks start to pay off. Most people find this level the most satisfying.
Hard needs box/line reduction and naked triples on top of that.
Expert needs an X-Wing in every puzzle, and Fiendish goes beyond every textbook technique.

Want a change from the classic grid? Killer Sudoku swaps most starting numbers for cages with sums, Jigsaw Sudoku replaces the 3 × 3 boxes with odd-shaped regions, Diagonal Sudoku makes both long diagonals count, and Mini Sudoku 6×6 is the whole game in a few minutes. Each variant book runs from easy to hard.

Stuck? Scan for a hint

Every classic puzzle in the books has a small QR code beside the grid. Scan it with your phone camera and the same puzzle opens in Ninebloom, where a hint names the technique that cracks the next square and shows you why. The app is free on Google Play, needs no account and works offline; more at ninebloom.leafyorb.com. You never need it to finish a book: every solution is printed at the back.

How to print them

Pick the file for your paper. Every book comes as a US Letter PDF and an A4 PDF.
Print at 100%. Choose “Actual size”, not “Fit to page”, so the 4-inch grid keeps squares big enough for pencil marks.
Print the pages you want. The puzzles are pages 5 to 64, two to a page, and the solutions follow, six to a page.
Print as often as you like. The personal-use license covers your own family and classroom.

Common questions

Are the Sudoku puzzles free?

The sampler is: ten puzzles, one from each book, with the solutions, and no email needed. The full books are $4.99 each, $11.99 for a trio and $29.99 for all ten.

Do the puzzles come with answers?

Yes. Every book has every solution at the back, six to a page, with the starting numbers in bold. The free sampler includes its solutions too.

Does every puzzle have one solution?

Yes. Each was checked by Ninebloom’s solver to have exactly one solution, and rated by the hardest technique it needs.

Are these the same puzzles as in the Ninebloom app?

No. They come from the same generator but are new, checked against every puzzle the app ships so none repeat. The QR codes open the book’s own puzzle in the app.
