Frequently Asked Questions
What types of puzzles can I generate?
KDP Builder generates 5 puzzle types: Sudoku (4×4, 6×6, 9×9, and 16×16 grids), Word Search (themed vocabulary with customizable word lists), Crosswords (auto-generated clues and symmetric grids), Mazes (multiple difficulty levels with solution paths), and Kakuro (sum-based number puzzles). You can mix types in a single book.
Are solution pages included automatically?
Yes. Every puzzle book includes a professionally formatted solutions section at the back. Word search solutions highlight found words in the grid, maze solutions show the correct path, Sudoku and Kakuro show completed number grids, and crossword solutions show all filled answers.
How much does it cost to create a puzzle book?
A complete puzzle book costs approximately 100–150 credits (from about $5 at our lowest credit rate), based on the median of books produced over the last 60 days. This includes the full interior PDF with puzzles and solutions, a professional AI-generated cover, paperback wrap PDF with spine, and all KDP metadata. New accounts get 75 free credits — enough to start your first puzzle book (a shorter interior fits within the free credits).
Is the output actually print-ready for Amazon KDP?
Absolutely. The generator produces KDP-compliant files: interior PDF with correct margins, bleed, and trim marks for any of 17 supported trim sizes; a paperback wrap PDF with calculated spine width and barcode zone; an ebook cover; 7 SEO-optimized keywords; BISAC categories; and a book description. You upload directly to KDP.
Can I customize the theme and difficulty?
Yes. You choose puzzle types, quantities, difficulty levels (Easy, Medium, Hard), and optional themes. For word search puzzles, the AI generates themed vocabulary matching your topic (e.g., 'Ocean Animals' or 'Space'). Section dividers organize puzzles by difficulty with decorative pages.
How long does it take to generate a puzzle book?
About 10 minutes from start to download. You configure your puzzle book in Step 1 (2 minutes), the AI generates everything in Steps 2–3 (5–6 minutes), and you download the complete KDP package in Step 4. No design skills or puzzle-solving expertise needed.
