Are these Sudoku puzzles free to print?

Yes. Every puzzle is completely free to print or save as a PDF, with no account or sign-up required.

Does each puzzle have a unique solution?

Yes. Puzzles are generated so that they have exactly one valid solution, which is what makes a Sudoku solvable by logic alone.

How do the difficulty levels differ?

Easy puzzles leave more numbers filled in, medium fewer, and hard the fewest — so harder puzzles require more advanced solving techniques.
