Control the counts, layouts, and book options for each section independently.
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.
Typical free generator

Frequently asked questions
Can I sell the Collection Builder 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?
When solutions are enabled, each section's answer pages are included in the same PDF, so the combined book is complete.
Which puzzle types can I combine?
You can mix multiple types — such as Sudoku, word search, maze, and crossword — into a single book, with a separate section for each type.
Can I order or shuffle the sections?
Yes. You arrange the sections yourself, so the puzzle types appear in whatever order you choose throughout the book.
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.
