Answer

# Can I sell sudoku books I make with a generator?

Updated 15 September 2026

Yes. The free tool makes one puzzle for personal use, but the sudoku interiors you export from Publisher Studio are yours to publish and sell on Amazon KDP. Every board is verified uniquely solvable, and one unlock re-exports the book at any trim.

The exported interiors from [Publisher Studio](https://www.oncebooks.com/kdp-sudoku-maker) are yours to publish. The book unlocks once and you can re-export it at any trim, as many formats as you like.

Because every board is uniquely solvable and the solutions are generated with the puzzles, you can ship a book that readers can trust, at any difficulty curve you choose.
