WHAT IS INCLUDED
The base engine
Elimination proof concept
The product claims to test its generated case for a single valid answer before export. This is a vendor claim rather than an independently verified result.
Clue-by-clue answer key
The seller describes answer material connecting each clue to the candidate it removes, which may help publishers proofread logic.
Puzzle difficulty options
Build for different audiences by adjusting the complexity and presentation. Always assess a printed proof for a real reader.
Book construction assistance
The promotional material discusses complete puzzle-book preparation, including introductory pages and answer sections.
Publishing-oriented workflow
Files intended for online publishing need extra checks for layout, trim sizes and platform compliance.
