The same code and settings always rebuild the exact same puzzles. Write it down to reprint or fix a book later.
One theme per line: Theme name: word, word, word. Each line becomes its own puzzle; 12 to 20 words per line works well. Spaces and punctuation inside words are removed, and accents are dropped (café becomes CAFE).
Theme name: word, word, word
One per line, up to 220 characters. Use your own writing or public-domain sayings; do not paste copyrighted quotes or song lyrics.
Puzzles come first, then a solutions section (4 answers per page). Margins follow KDP's gutter table for the final page count; no bleed. Short books get lined Notes pages to reach KDP's 24-page minimum. On KDP, choose black ink, white paper and No Bleed.
Free version: up to 10 puzzles per book and a small "made with" line on each page.
