Printable sudoku
Sudoku booklets in PDF, from an easy level to get started to a hard level for regulars. Every grid has a single solution, checked by our solver; the solutions are on the last pages.
Every row, every column and every 3 × 3 block contains the digits 1 to 9.
How it works
Pick a level
Easy to learn, medium to practise, hard to test yourself. The level depends on the reasoning techniques needed, not only on how many digits are given.
Set up the booklet
From 1 to 20 puzzles, on A4 or Letter, with or without the solutions. The button shows the page count of the PDF before it is built.
Print
Two puzzles per page with large digits, easy to read and to write in pencil. The solutions are grouped at the end, four per page.
Printing tips
Choose “Actual size” or “100%” in the print dialog, not “Fit to page”: cells are at least 7 mm wide, enough room for a digit and pencil notes. Black and white is enough. For a class or a club, print the solutions on a separate sheet and keep it. Double-sided printing works well, but remember to remove the solutions page from the copies you hand out.
Frequently asked questions
Does every puzzle have a single solution?
Yes. Each grid is checked by a solver before layout: a grid with two solutions would be discarded. You can solve it by deduction, without ever guessing.
How is the level chosen?
By the techniques needed to solve the grid. On easy, spotting the only possible cell for a digit is enough. From medium, you also need pairs and alignments inside blocks.
Can I use them in class, in a club or in a newsletter?
Yes, freely, including printing them in quantity. Only reselling the files is not allowed.
Are my settings saved?
On your device only, so you get the same level next time. Nothing is sent to a server.
