Questions
- How do I make a fill-in book for KDP?
- Pick a template. Add words. Preview. Export.
- Is every fill-in unique?
- Every puzzle is checked and the answer key matches the page.
- Will KDP reject my puzzle book?
- KDP rejects files, not puzzle types. The usual causes are margins, missing fonts, low-resolution images and a wrong page count. The studio checks these before you export, and the free PDF checker reads any file.
