Frequently asked questions
- Does every sudoku have only one solution?
- Yes. The engine removes clues one by one and keeps a removal only if the puzzle still has exactly one solution, so you never need to guess.
- Which sizes and levels are there?
- 4×4 and 6×6 for children, the classic 9×9, and 12×12 and 16×16 for a challenge, each in four levels from easy to expert. Easier levels keep more clues.
- Can I print it?
- Yes. Download a PDF (A4 or Letter), PNG or SVG with the puzzle on the first page and the solution on the second, free and with no watermark.
