How Sudoku Prints works
Generate a printable Sudoku set in four steps.
Choose a difficulty
Easy, Medium, Hard or Expert. Every level produces a puzzle with exactly one solution.
Generate a puzzle
Pick how many puzzles you want and how many per A4 page (1, 2, 4, 6 or 8). Click Generate. Everything is verified before it appears.
Print or save as PDF
Click Print. From the browser's print dialog you can send to a printer or choose "Save as PDF".
The layouts are designed for A4. For US Letter, choose Letter and Fit to printable area in your printer settings, then check the preview for clipped borders. Scaling can make the grids slightly smaller. Disable browser headers and footers if they add unwanted text.
Use the answer key
If you keep "Include answer key" enabled, the matching solutions are printed on separate pages so you can check or hand them out.
