Frequently asked questions
Is every puzzle solvable?

Any strategy?
Solve the top row first, then the left column, and keep shrinking the puzzle. Save the last two rows for the end.
Is Sliding Number Puzzle free?
Yes. Sliding Number Puzzle is free to use with no sign-up and no watermark.

No. Everything is calculated in your browser. Nothing you enter is sent to a server or stored.
Does it work on my phone?
Yes. It works in any modern browser on Windows, Mac, Linux, Android and iPhone. Very large files may be slow on older phones.
