Sudoku Book Generator — KDP Publishing Guides

Sudoku sells steadily because every buyer wants fresh puzzles at a difficulty that suits them. The printable sudoku generator guide puts a working generator on the page: choose easy, medium or hard, build a new puzzle, and show the answer when you need it.

The free printables library has a kids' sudoku sheet with two large easy grids and an answer key; easy, medium and hard grids are in the printable sudoku generator. For a whole book interior with solution pages, the KDP sudoku generator in the Octozia dashboard is the paid option, available on a 3-day trial.
