Sudoku book generator

kdpbook.io's sudoku book generator turns a one-line theme into a 108-page sudoku 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.

A sudoku book with large-print 9x9 puzzles (6x6 grids for early readers) that go from easy to hard, each checked by a solver to have exactly one solution, with the 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

Sudoku book questions

Does every sudoku have exactly one solution?

Yes. Each puzzle is generated and then checked by a solver, and kept only with a single solution, so solvers never have to guess. The puzzles go from easy to medium to hard through the book, with the solutions at the back.

How many pages should a sudoku book have?

Our sudoku 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.

Which grid sizes does a sudoku book use?

The classic 9 × 9 grid for middle-grade readers, teens and adults, one big grid per page. Books for early readers switch to smaller 6 × 6 grids automatically. The default book is 108 pages at 8.5 × 11 in.

Can I publish a sudoku 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 sudoku book in Spanish, German or French?

Yes. kdpbook.io can make a sudoku 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 sudoku book has no Kindle edition. 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 sudoku book cost on kdpbook.io?

The default sudoku book (108 pages) is estimated at 460 credits, about $5. Your first sudoku 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 sudoku 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 sudoku book use KDP Expanded Distribution?

Trim and paper eligible; distributors may decline sudoku and 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 sudoku 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 sudoku 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. 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.
