Who the KDP Book Builder Is For
Most puzzle generators — including our own single-type makers — produce one puzzle type at a time, which means a KDP publisher assembling a 100-puzzle variety book has to run five separate tools, download five separate PDFs, and manually merge them into one manuscript. The Book Builder is built for exactly that publisher: it takes a mix of puzzle types and counts, generates the whole interior in one server-side pass, and returns a single print-ready PDF with continuous numbering and one combined solutions section. That’s a genuinely underserved niche — almost no free tool assembles a mixed-type book end to end.
Three Book Recipes to Start From
- Large-print easy logic sampler— 20 easy Calcudoku + 20 easy Star Battle, 8.5×11 trim. A gentle, senior-friendly variety book with big grids and short sessions.
- Classic 6×9 variety pack— 15 medium Kakuro + 15 medium Killer Sudoku + 10 medium Nonogram, 6×9 trim. The standard KDP puzzle-book format and trim size.
- Progressive challenge book— 40 Calcudoku on the Easy→Hard ramp + 20 Star Battle on the same ramp, 7×10 trim. Puzzles get harder as the reader progresses through each section.
Frequently Asked Questions
Can I sell books made with this on Amazon KDP?
Yes. Books generated with the Book Builder carry the same commercial license as every PuzzlePage generator — you own the output and can sell it on Amazon KDP, Etsy, or anywhere else with no royalty or attribution required. See the full license →.
What trim sizes are supported?
Three KDP-accepted trim sizes: 6×9” (the classic KDP puzzle-book trim), 7×10”, and 8.5×11” Letter (often used for large-print editions).
How is the answer key formatted?
All answer keys are packed into a single solutions section at the back of the book, in the same order as the puzzles, so readers can flip straight to the matching page number.
How many puzzles can a book have?
Books run from 18 to 120 puzzles (KDP requires at least 24 interior pages) across up to 6 sections. Building an interior requires a KDP Publisher plan (single-puzzle generators stay free). Daily build limits apply: 15 books/day on Publisher, 40 on Pro.
