Frequently asked questions

How does the AI sudoku generator work?

We solve a randomised 9×9 grid via backtracking, then carve out cells per difficulty level. The solution and given digits are exported together so every puzzle ships with an answer key.

How many sudoku puzzles can I put in one book?

Most KDP-friendly sudoku books ship with 100–200 puzzles. Use the Puzzle Studio's preset to drop in a graded 100-puzzle pack (easy → expert) in one click, or curate your own mix.

What page sizes are supported?

Sudoku pages export inside any KDP trim — 8.5×11, 8×10, 7×10 and more — with proper bleed and margins for print-on-demand.

Can I sell the sudoku books I create?

Yes. You own 100% commercial rights to anything generated in the Puzzle Studio. Publish on Amazon KDP, Etsy or your own store.

Is the answer key included?

Every sudoku book exports with a clean solutions appendix in the back — no extra clicks required.
