Fresh puzzles, guaranteed unique
Each grid is generated from the puzzle number and the page, so a 50-page book contains 50 pages of different puzzles. Clues are removed in symmetric pairs while the puzzle keeps a single solution: easy puzzles keep about 38 clues, medium about 30, and hard ones as few as the generator can manage.
How to play
Fill every empty cell with a digit from 1 to 9 so that each row, each column and each 3×3 box contains every digit once.
Printing tips
Print large-print easy puzzles one per page for beginners and older eyes, or four per page in an A5 booklet for a pocket puzzle book.
Free sample PDFs
Print at 100% (actual size). Made with the same engine as the maker, so the spacing is exact.
Frequently asked questions
Do the puzzles have one solution?
Yes. Each puzzle is generated in your browser and a solver checks that exactly one solution exists before it is printed.
Where are the answers?
With Solutions at the bottom on, the solved grids are printed small and upside down at the foot of each page. Turn it off for answer-free sheets.
How do I get more puzzles?
Add pages: every page has new puzzles. Change the puzzle number for a completely different set.
