How it works
From idea to manuscript in three steps
Configure your book
Pick a title, trim size (6×9 or 8.5×11), and your puzzle mix — sudoku, word search, maze, samurai — with difficulty per section.
We generate & verify
Every single puzzle is generated fresh and machine-proven: unique sudoku solutions, findable words, solvable mazes. No duds, ever.
Upload to KDP
Download a print-ready PDF — correct margins, mirrored gutter, page numbers, and a full solutions section — and publish it.
Features
Everything a puzzle publisher needs, nothing you have to babysit
Four puzzle types
Sudoku, word search, maze, and samurai sudoku — mix them freely in one book, with easy, medium, and hard difficulty.
Machine-verified quality
An independent validator proves every puzzle before it can reach a page: exactly one sudoku solution, every word findable, every maze solvable.
KDP-safe layout
0.5″ margins, a proper 0.75″ mirrored binding gutter, and page numbers outside the puzzle area — sized to pass Amazon's previewer.
Your own word lists
Word searches from 12 built-in themes or your own saved lists — family names, local places, niche topics your readers love.
Endless unique books
Every book is generated from its own seed — no shared puzzle bank, no duplicate content risk between your titles or anyone else's.
Solutions included
A tidy solutions section is appended automatically — compact grids, highlighted word paths, traced maze routes — numbered to match.

FAQ
Common questions
Is the PDF really ready for Amazon KDP?＋
Yes. Books use KDP's recommended trim sizes (6×9 and 8.5×11) with 0.5″ outer margins, a 0.75″ mirrored binding gutter, embedded fonts, and page numbers kept clear of the puzzle area. Upload the downloaded file as your manuscript.
Do I own the books I generate?＋
Completely. Every book is generated uniquely for you and you keep full commercial rights — publish it, sell it, keep 100% of your royalties.
How do I know the puzzles are actually solvable?＋
Every puzzle passes an independent machine check before it's allowed onto a page: sudoku are proven to have exactly one solution, every word-search word is verified findable, and every maze route is re-solved. A puzzle that can't be proven correct never ships.
Will my books duplicate someone else's?＋
No. Puzzles are generated from a unique random seed per book rather than drawn from a shared bank, so two books never share content.
Can I use my own words in word searches?＋
Yes — on the Pro plan you can save custom word lists (names, places, themes) and build word searches from them. All plans include 12 built-in family-friendly themes.
Can I cancel anytime?＋
Yes. Manage or cancel your subscription any time from the dashboard via the billing portal — no emails, no phone calls.
