Puzzle book generator

kdpbook.io's puzzle book generator turns a one-line theme into a 108-page puzzle book at 8.5 × 11 in: it generates the pages in code and paints the cover, then exports the interior PDF, the full-wrap cover PDF and a listing sheet for KDP. The default book costs about 460 credits (≈ $5), within the 2,000 free signup credits as a watermarked preview.

Word search, sudoku, criss-cross, cryptograms and more for adults and seniors, large print by default, every puzzle verified solvable, solutions at the back.

To sell the book, export it on a paid plan: every plan from $25/month (Starter, 2,500 credits a month) gives watermark-free files with a commercial license, and kdpbook.io takes no royalty. See plans

Puzzle book questions

Which puzzles can a puzzle book mix?

It follows the reader: the default large-print book for seniors mixes word searches, sudoku, criss-cross puzzles, cryptograms, word scrambles and mazes, one kind per section, and books for adults, teens or kids swap in the kinds that suit them (hangman for kids, for example). Each section goes from easy to hard. The grids are built in code, and an AI only writes the themed word lists, clues and cryptogram quotes.

How many pages should a puzzle book have?

Our puzzle book template runs 24–300 pages and defaults to 108. For this ink and trim, KDP accepts 24–590 pages. KDP counts every page, including front matter and blank pages, and rounds odd counts up to an even number.

Are the answers included and checked?

Yes. Every word search word is placed in its grid, every sudoku is checked by a solver for a single solution, and the solutions are printed at the back, several small answer grids to a page.

Can I publish a puzzle book as a Kindle eBook?

No. Not offered: KDP lists this kind of book as unsuited to Kindle, so it is print only. You can publish it as a paperback or hardcover.

Can I make a puzzle book in Spanish, German or French?

Yes. kdpbook.io can make a puzzle book in 27 languages that KDP prints, including English, Spanish, German, French, Italian, Portuguese and Dutch. Arabic, Hindi, Chinese (Traditional), Tamil, Marathi, Gujarati and Malayalam are left out: KDP publishes them only as Kindle eBooks, and a puzzle book has no Kindle edition. Its word searches, word scrambles, hangman games, criss-cross puzzles and cryptograms keep the letters each alphabet adds: Ñ in Spanish, Galician and Basque, Å Ä Ö in Swedish and Finnish, Æ Ø Å in Danish and Norwegian, the Polish and Icelandic letters, and Ukrainian in Cyrillic; other accents are dropped in the grid and the word list (É becomes E), and German Ä, Ö, Ü and ß are written AE, OE, UE and SS. In Japanese, Hebrew, Persian and Yiddish it is made without them. A few words its pages print stay in English: Start and Finish. The kdpbook.io editor is in English, and the Book assistant replies in English, French, Spanish, German, Italian or Portuguese, following the language you write in.

How many credits does a puzzle book cost on kdpbook.io?

The default puzzle book (108 pages) is estimated at 460 credits, about $5. Your first puzzle book fits in the 2,000 free signup credits (preview watermark; clean files on any paid plan). You see the exact estimate before you launch, only what is produced is charged, and the rest of the hold goes back to your balance.

Can I sell a puzzle book made with kdpbook.io on Amazon?

Yes, on a paid plan (from $25/month): its files have no watermark and come with a commercial license, while free-plan files are a watermarked preview. Plans: kdpbook.io/pricing.

Can a puzzle book use KDP Expanded Distribution?

Trim and paper eligible; distributors may decline puzzle books (KDP list). You can enroll the paperback (it offers the paperback to bookstores and libraries outside Amazon at a 40% royalty), but its distributors may not accept this kind of book. A book they decline is removed from Expanded Distribution and stays on sale on Amazon.

Is a puzzle book a low-content book on KDP?

No. KDP says low-content doesn't typically include activity books such as puzzle books or coloring books, because their pages aren't repetitive. A puzzle book is published like any other book and can use the free KDP ISBN.

Do I have to tell Amazon the book was made with AI?

Yes, for AI-generated content. KDP asks you to declare AI-generated text, images or translations when you publish or republish a book, even if you edited them substantially. Text kdpbook writes is AI-generated. The cover art kdpbook paints is an AI-generated image; the interior pages are generated in code, not drawn by an AI. The export sheet pre-fills the answers from what was actually generated for your book.
