Puzzle-Designer Playtest Journals: Low-Competition KDP Niches for Indie Puzzle Creators

This episode shows how two tightly focused medium-content books—an Escape Room & Puzzle Playtest Journal and a Logic-Puzzle Designer Template Book (Killer Sudoku, Nonogram, Puzzle Grid builders)—are practical, low-competition KDP winners. I break down real buyer intent (designers, indie publishers, escape-room operators), show simple data signals you can pull in minutes, and give exact AI prompts to generate interiors, sample entries, and keyword clusters. You’ll get a step-by-step validation path that fits a one-hour publishing sprint plus a quick profit model so you know expected margins and time-to-break-even. Ideal for authors who want niche-first ideas that convert because they solve a workflow problem for creators—not generic hobby notebooks. No hype, just reproducible steps to publish a professional interior, optimize your listing, and test with targeted communities.
