How it works

From idea to manuscript in three steps

1

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.

2

We generate & verify

Every puzzle is generated fresh and machine-proven: unique sudoku solutions, findable words, solvable mazes. No duds, ever.

3

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 reaches 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.

Judge the output first

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.

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 solvable?

Every puzzle passes an independent machine check before it is allowed onto a page.

Will my books duplicate someone else's?

No. Puzzles are generated from a unique random seed per book, 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. All plans include 12 built-in family-friendly English themes.

Can I cancel anytime?

Yes. Manage or cancel your subscription any time from the dashboard via the billing portal.
