Sometimes you want to solve away from a screen — on a train, over coffee, or with a pencil and a cup of tea. These free printable sudoku PDFs are made for exactly that. Each file holds six puzzles at one difficulty level, followed by a full solutions page so you can check your work.
Every puzzle is computer-generated with a guaranteed single solution, so each sheet can be finished by logic alone — the same promise as the puzzles you play online. Print on standard US Letter paper; the grids are sized to leave room for pencil marks.

Printable vs. playing online
Printable and on-screen sudoku suit different moments. On paper you can scribble candidates freely and there is no timer looking over your shoulder. Online, the board checks your logic instantly and there is nothing to print or carry. The rules are identical either way — if you are new, the how to play sudoku guide covers everything before you start.
How to solve a printed grid
- Start with a digit that already appears often and scan each 3×3 box for its only legal home.
- When scanning stalls, pencil the candidates into each empty cell in light marks.
- Erase candidates as you place numbers; watch for cells left with a single option.
- Never guess — on a correct grid the next step is always deducible.
For the full method and the named techniques (singles, pairs, and beyond), see the sudoku techniques guide.
Printing tips
- Print at 100% scale (not “fit to page”) so squares stay square.
- Black-and-white is fine — the sheets use no color.
- One puzzle per page leaves the most room for pencil marks; solutions are grouped at the end.
Frequently asked questions
Are these printable sudoku puzzles free?
Yes. Every PDF on this page is free to download and print for personal use, with no account required.
Does each printable puzzle have a single solution?
Yes. All puzzles are generated with a verified unique solution, so each one can be completed by logic without guessing. The answers are included at the end of every file.
What paper size are the PDFs?
They are laid out for US Letter. They also print cleanly on A4 if you select “fit to page,” though the grid will be slightly smaller.
How is the difficulty decided?
Difficulty is based on how many starting numbers each puzzle keeps and which techniques are needed to finish. Easy sheets keep more givens and yield to simple scanning; evil sheets keep the fewest and require advanced logic.
