You’re the across and the down around here
Welcome to the KDP Book Builder — no clue needed, you're already the answer key. We’re actively building new features, and we’re here to help at every step. If something goes sideways, or you’ve thought of a feature that would make your books better, and we’ll work it into the grid as fast as we can. Your puzzle books are our number one priority — everything else is just filler squares.

The Book Builder is part of the KDP Publisher plans (from $14.99/mo): full books up to 120 puzzles with a commercial license. There are no free builds, and generator Premium does not include it.
Mixed-type, KDP-ready interior
Build your interior first, or enter a page count to plan ahead.
Enter a page count between 24 and 828 to see spine and wrap dimensions.
Cover files upload separately from the interior on KDP. Build the wrap at exactly the size above at 300 DPI, with the barcode zone (bottom-right of the back panel) left clear.
Title + copyright pages — your book title, subtitle, and a standard copyright page with your author name, so the interior reads as professionally published.
One puzzle per page — with short instructions for each puzzle type and physical page numbers, so readers never need outside rules.
KDP compliance report — every build returns the exact page count plus a checklist of the checks Amazon runs (page range, margins vs. gutter tier, file size, trademark scan of your title), so you upload knowing it will be accepted.
Packed solutions section — every answer key is compiled at the back of the book, continuously numbered to match the puzzles.
Commercial license — sell books built with this generator on Amazon KDP, Etsy, or anywhere else. See the full license →
KDP-compliant formatting— accepted trim sizes, margins that satisfy KDP's gutter requirements at every possible book length, embedded fonts, no bleed elements or crop marks, and the 24-page minimum enforced automatically. Upload the PDF as your interior file, as-is.
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. This builder mixes all 18 PuzzlePage engines — word search, crossword, cryptogram, word scramble, mazes, and the full logic range — in 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.
- Themed word-puzzle book— 20 themed Word Search + 15 Crossword + 15 Cryptogram quotes, 8.5×11 trim. The best-selling KDP word-book format, straight from the built-in theme libraries.
- 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 18 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.
