## What is PuzzleForge?

PuzzleForge turns your iPhone into a complete sudoku book production studio. Generate hundreds of quality-guaranteed puzzles, lay them out as a real book, and export a print-ready PDF you can upload to Amazon KDP or hand out in class.

QUALITY YOU CAN PUT YOUR NAME ON
- Every puzzle is machine-verified to have exactly one solution
- Four difficulty levels (Easy, Medium, Hard, Expert), judged by the solving techniques actually required
- Puzzles and the answer key are numbered and matched automatically, so they can never drift apart
- Stable seeds: the same book always regenerates the same puzzles

BUILT FOR SELF-PUBLISHERS
- Trim sizes: 6 x 9 in, 8.5 x 11 in, and A4
- Automatic gutter (binding margin) calculated from your page count, following KDP recommendations, with manual override
- Title page, running headers, page numbers, and an answer key chapter, each one optional
- Choose 1, 2, 4, or 6 puzzles per page
- No watermarks and no app branding inside your PDF. The book is your product

FAST, OFFLINE, PRIVATE
- Generate up to 600 puzzles per book in one batch, with live progress and cancel
- Preview every page exactly as it will print
- Works completely offline. Your books never leave your device
- Back up and restore all projects as a JSON file

MADE FOR
- KDP and other print-on-demand publishers creating low-content puzzle books
- Teachers and tutors preparing difficulty-graded practice sheets
- Anyone who wants to print a personal sudoku collection

One-time purchase. No subscription, no ads, no sign-up.
