Practical guides to publishing puzzle and activity books — written from actually doing it, with the real numbers rather than the usual affiliate hand-waving.
The complete walkthrough: choosing a niche that actually sells, how many puzzles a book needs, the print specifications Amazon enforces, exactly what you earn per copy, and the eight steps from blank page to a live listing. Includes the real royalty maths for a 38-page and a 120-page book.
Book Bolt, A Book Creator, Tangent Templates, PuzzleBindery and the free options — what each one actually does, what it costs over a year, and which is right for you. Including the cases where we are the wrong choice.
Why Amazon rejects interiors and covers, what every number in the print specification means, and the exact formulas — gutter tiers by page count, bleed dimensions, and the spine multipliers for white and cream paper.

Gutter tiers, the interior-versus-cover bleed difference, spine width per paper stock and the page ceilings nobody mentions. I’ll send the guide and a note when Amazon changes the rules.
