Questions
- How do I make a sudoku book for KDP?
- Pick the sudoku template. Set grid and difficulty mix. Check uniqueness in the report. Export.
- Is every sudoku 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.
