What Is Logic Rails?
Logic Rails is a lightweight, cloud-based software application that allows you to automatically generate unique Train Track deduction puzzles right inside your browser. Instead of manually drawing paths or trying to piece together complex layouts, the tool builds clean, professional-grade puzzles complete with matching solutions.
The core concept is built around routing train tracks across a grid based on numerical clues. It offers a unique visual challenge that feels entirely different from standard puzzle books currently crowding the marketplace.
Standout Features for Publishers
- Automatic Generation: Generate unique puzzles instantly without worrying about duplicate content or manual trial-and-error.
- Flexible Grid & Trim Sizes: Create puzzles across various grid dimensions (from 6×6 up to 15×15) and standard book trim sizes (6×9, 8×10, and 8.5×11).
- True SVG Output: Every puzzle and solution exports as a crisp, scalable SVG file. This means infinite scaling without losing print quality, making it seamless to drop designs into Canva, PowerPoint, or Affinity Publisher.
- Open Routes & Closed Loops: Customize the gameplay style to match your audience, offering plenty of variety for your books and activity packs.
- Full Commercial Rights: Any puzzles you generate can be sold commercially in your KDP books, Etsy downloads, membership sites, or lead magnets.
Who Is This For?
- Amazon KDP Publishers: Looking to expand your portfolio beyond standard low-content notebooks and crowded puzzle categories.
- Etsy Shop Owners: Selling printable logic packs, classroom worksheets, or brain-teaser activity bundles.
- Teachers & Content Creators: Needing quick, clean math and logic puzzles for kids or adult learners.
Final Verdict
If you want to speed up your production workflow and publish books that stand out from the “me-too” puzzle crowd, Logic Rails offers an affordable, easy-to-use solution. With a one-time price point and zero special software requirements (no Photoshop or Illustrator needed), it’s a great asset for scaling a low-content publishing business.
