Fresh sudoku, whenever you want it

Every press of New puzzles gives you a new set, so there is always another one to print. Each puzzle has exactly one answer, and the numbers are laid out symmetrically like the ones in the newspaper.

For a coffee break, one large Medium puzzle on a page is easy on the eyes. For a long trip or a quiet week, make a 10 page booklet with six Hard puzzles a page. The 4 by 4 and 6 by 6 grids are a gentle way for kids to learn the rules.

Everything happens in your browser and nothing is uploaded. Sudoku and colouring go well together as screen-free breaks, and our free colouring pages are a good reward once the last square is filled.

Questions, answered

Are these sudoku puzzles free to print?
Yes. Make as many as you like, print them or download the PDF. There is no sign-up and no watermark.
Does every puzzle have only one answer?
Yes. Each puzzle is checked as it is made, so there is exactly one way to fill the grid. Easy and Medium can be solved square by square without ever guessing.
What is the difference between Easy, Medium, Hard and Expert?
Easy gives about 40 of the 81 numbers and Medium about 32. Hard gives around 27 and usually needs you to look ahead. Expert gives as few as the puzzle allows, often 22 to 26, and is picked to need more than the simple steps.
Is there sudoku for kids?
Yes. Choose a 4 by 4 grid (numbers 1 to 4) or a 6 by 6 grid (numbers 1 to 6). They use the same rules with fewer squares, which makes them a good first step before the full 9 by 9.
Can I print a sudoku book?
Yes. Pick up to 10 pages with 1, 2, 4 or 6 puzzles on each, so up to 60 different puzzles in one PDF. The answers come on pages at the end, six to a page.
Will it print on Letter and A4 paper?
Yes. Choose US Letter or A4 before you print or download, and the grids are sized for that sheet.
