# The KDP cryptogram maker

Generate a whole graded cryptogram book, then export it at every KDP trim, print-ready at 300 DPI. Make one puzzle free in your browser, unlock a full project for a one-time fee, and export unlimited formats forever.

[Open Publisher Studio](https://app.oncebooks.com/publisher-studio/cryptogram)[Make one free first](https://www.oncebooks.com/tools/cryptogram-generator)

$4.99 once per project. Unlimited exports, every trim. No subscription.

## Every puzzle decodes one way

Every cipher is built from a curated, family-safe saying and proved to round-trip to exactly one quotation before it prints. The decoded quote prints as the answer key.

## Every KDP trim, 300 DPI

Pick any of KDP's 17 trim sizes, from 5.06 by 7.81 up to 8.27 by 11.69, with correct margins and gutter. The single interior file you upload passes KDP review.

## Generate once, export forever

One project unlocks for $4.99. After that, re-export any trim, any time. No monthly subscription and nothing to cancel.

## How it works

1. Try a free puzzle. Use the free generator in your browser to make one cryptogram and its answer, so you can see the output before you commit.
2. Pick a difficulty curve. In Publisher Studio, choose how many puzzles at each grade; harder grades reveal fewer starting letters. The studio builds the whole graded book.
3. Choose your KDP trim. Pick a trim size. The interior is sized with the right margins and gutter for the page count so it passes KDP review.
4. Unlock once, export any size. Unlock the project for $4.99, then export the print-ready interior and solutions PDFs at any trim, as often as you like.

## Questions

**How much does it cost?**

A project unlocks for $4.99, paid once. After that you can export the interior and solutions PDFs at any KDP trim, as many formats as you like, forever. There is no subscription.

**What do I get when I export?**

One print-ready 300 DPI interior PDF, with the decoded answers at the back, sized for the KDP trim you choose. That interior is the single file you upload to KDP. You also get a separate solutions PDF.

**Are the puzzles guaranteed to decode one way?**

Yes. Every cipher is proved to round-trip to exactly one quotation before it enters the book. The printed answer matches every puzzle.

**Where do the quotations come from?**

From a hand-curated, family-safe bank of traditional proverbs and sayings, reviewed before it ships. There are no modern copyrighted quotes.

**Can I sell the books I make?**

Yes. The exported interiors are yours to publish and sell on Amazon KDP or print yourself. The per-project unlock covers unlimited exports of that project.
