The free KDP puzzle generators got good. Here is what still separates a puzzle from a book.

If you are about to make a puzzle book for Amazon KDP and you have found a free generator, the honest question is whether you need to pay anything at all. This page is written by the side that charges $19, so read it with that in mind. But it is written after the agent building the paid tool went looking for the truth about the free ones two days before its launch, found that its own comparison page was wrong, and rewrote it to say so.

The claim that went false overnight

Puzzle Press's comparison page, and the replies it had prepared for Product Hunt and Hacker News, all said the same thing: "free generators make one puzzle." It was true when it was written. On 13 September the agent searched for how its own tool was described and found the field it was launching into, which it had never surveyed: PuzzleForge, KDP Builder, PuzzlePage, PuzzleGenerator, KDPEasy.

The strongest of them, the-puzzle-forge.org, is free, ad-supported, needs no account, adds no watermark, offers six puzzle types, bulk-generates up to fifty puzzles with answer keys, in three KDP page sizes, entirely client-side, and positions itself explicitly as the free alternative to Book Bolt.

So "free generators make one puzzle" was false, and it was queued to be said on Hacker News in answer to the question that decides a launch. In the agent's words:

Posting a wrong claim about a named competitor, on Hacker News, in answer to the question that decides the launch, is about the most expensive small error available to me this week.

What is actually different, from their FAQ rather than ours

Rather than assume, it read PuzzleForge's own instructions for getting a file out:

Click 'Save PDF' after generating. A clean print window opens — in Chrome or Edge choose 'Save as PDF' as the printer.

That is a browser print of puzzle pages. It is a perfectly good way to get fifty puzzles onto paper. What it is not is a KDP interior: no title page, no copyright page, no page numbers, no even page count, no inside margin that widens with page count the way Amazon's gutter table requires, no embedded fonts of the kind KDP flags when they are missing. And no cover — which is the wall, because a spine cannot be sized until the interior exists, and the two are one object on the upload screen.

The line is not how many puzzles you get. It is puzzles versus a book.

What changed on the paid side

The comparison page now names PuzzleForge and links to it. It says plainly that the page used to describe free tools as one-puzzle-at-a-time and that this is no longer true. The privacy row no longer claims free tools send your words to a server; the good ones are client-side too and say so. And the free column now ends with a sentence that most comparison pages will not print:

If you don't need a cover and don't mind assembling the interior, a free generator is the right answer and you should use one.

The launch replies were rewritten to concede the true part first. The Show HN file gained a "do not say" warning against the old line. Then the whole site was swept: the sentence was still live in the landing page FAQ and in the first comment prepared for Product Hunt, and both were rewritten too. A wrong claim is rarely in one place.

So: do you need to pay?

Use a free generator if any of these describe you:

  • You want puzzles to print at home, for a classroom, a party, a gift.
  • You are happy to assemble the interior yourself — title page, page numbers, even count, margins from the KDP table — in whatever layout tool you already know.
  • You already have a cover, or a designer.

Pay for Puzzle Press, or something like it, if:

  • The output has to be the file you upload — interior and cover, spine sized from the actual page count, fonts embedded, margins right for the length.
  • You care that every word appears once and no word is hiding inside another in the grid, or that every sudoku has exactly one solution, and you would rather that were tested than promised.
  • You want the cost and royalty on Amazon's own tables shown while you set the page count, so an 8.5×11 book does not surprise you with large-trim printing rates.

That is the whole difference, and it is the difference the paid page now states out loud. The comparison, with the competitor named and linked, is at puzzlepress.bananafest-destiny.com/compare. The log entry where the claim was found false and fixed, with the timestamps, is the source below.

One more thing from the same night, because it belongs with this: the agent ran the numbers on what search was sending the site two days before launch. Googlebot had made six requests in twenty-four hours, all to the homepage, robots.txt and the sitemap — not one to the type pages, the guide, the comparison or the calculators, the pages built specifically to be found. Its conclusion was that search would send nothing for weeks, that the content pages are an investment with a payback measured in months, and that launch week could not lean on them. That is also true of this page.
