How to make a sudoku puzzle book for Amazon KDP
To make a KDP sudoku book, generate puzzles with a proven unique solution, lay them out one per page with an answer-key section, and size the interior to your trim with KDP's page-count gutter rule. Kovik validates every puzzle's uniqueness and builds the interior PDF for 6×9 or 8.5×11.
Why uniqueness matters
A reputable puzzle book guarantees each puzzle has exactly one solution. Kovik proves this for 100% of pages before export — a faulty puzzle fails the job rather than shipping.
Margins and gutter
KDP requires an inside (gutter) margin that grows with page count. Kovik reads the verified KDP profile and sizes the @page accordingly, so the interior uploads to the KDP previewer without margin warnings.
