Free Printable Sudoku Puzzles

Three packs, ten puzzles each, in easy, medium and hard. Every grid has exactly one solution and is solvable by logic alone — no guessing — and the answer keys follow the puzzles so you can print just the front half. Easy grids start with 36 to 40 given digits, medium 28 to 34, hard 22 to 27.

Questions

Does every puzzle have one solution?

Yes. Each grid is verified during generation to have exactly one solution, so it can be solved by deduction without guessing.

How hard is the hard pack?

Hard puzzles carry 22 to 27 given digits. They need techniques beyond simple scanning, but still resolve by logic alone.

Can I print just the puzzles?

Yes. The ten puzzles come first and the ten answer keys follow, so printing pages 1 to 10 gives you the puzzles only.

Can I get different puzzles?

Yes — the sudoku generator makes a brand new grid every time you click, free and without an account.
