How to print your puzzles
- Choose the puzzle. Classic Sudoku is selected. You can switch to Killer, Sudoku X, Jigsaw, Mini 6 by 6, Kids 4 by 4 or the giant 16 by 16.
- Pick the level. Six levels for classic Sudoku, from Easy with about 42 starting numbers to Extreme with about 22.

The pages are sized to fit both A4 and US Letter paper, so you do not need to change any printer settings.
How many puzzles on a page?
- 1 a page gives big squares that are easy to read, good for older eyes or for putting on a wall in a classroom.
- 2 a page leaves room to write notes in the corners of each square, which helps on Hard and above.
- 4 a page is the size most newspapers use. It is the default.
- 6 a page puts most of a week of puzzles on one sheet. Fold it in half and it goes in a pocket or a bag.
The six levels
The difference between levels is how many numbers each puzzle starts with. Fewer numbers means fewer easy moves and more use of notes.
| Level | Starting numbers | Good for |
|---|---|---|
| Easy | About 42 | Beginners and a calm few minutes |
| Medium | About 36 | Everyday solving |
| Hard | About 31 | Players who use notes |
| Expert | About 27 | Pointing pairs and patience |
| Master | About 24 | Very hard puzzles, also called Evil |
| Extreme | About 22 | The hardest we make |
Want to know what each level asks of you before you print? See Easy, Hard or Evil Sudoku, or play the same levels on screen on the home page.
Solving on paper
- Use a pencil. Even good solvers rub things out on the harder levels.
- Write notes small. Put possible numbers in the corners of a square, in the same place each time: 1 top left, 9 bottom right. You will read them faster.
- Cross off as you go. When you place a number, look along its row, column and box and remove it from any notes there.
- Stuck? Type the puzzle into our Sudoku solver and it will show you the next step and explain why, without giving away the rest.

No. New puzzles are made in your browser each time. To keep a set, choose Save as PDF when you print.
