Why not use a free generator?
Free generators are fine for a worksheet or a rainy afternoon. A book you sell on Amazon KDP needs the right to sell it, and pages made for print.

Frequently asked questions
Can I sell the Fillomino books I create?
Yes. Commercial use is included: everything you generate and export is yours to publish and sell on Amazon KDP or any other platform, with no royalties or per-book fees.
Do the PDFs include the solutions?
Every export includes matching answer pages alongside the puzzle pages, so your book is complete.
Can I change the grid size and difficulty?
Yes. You can adjust the grid size and clue density so each book ranges from small, gentle grids to larger, harder ones.
Do I need an account to use the generator?
You can browse this page without an account, but generating and exporting puzzles requires signing in and credits.
Can I use designs from a free online generator in a book I sell?
Check its license first. Many free generators allow personal or classroom use only, so putting what they make into a book you sell can break their terms. Their downloads are usually sized for screens rather than print, too. Everything you create in Publish Aid is licensed for commercial use and exported as a print-ready PDF sized for Amazon KDP.
