What is the Sudoku studio?

Sudoku is a studio of BookyAI Activity Studio, a paid add-on for the BookyAI desktop app. It builds complete sudoku books ready for Amazon KDP. Every puzzle is generated on your computer, proven to have exactly one solution by two different methods, and given a level measured by solving it step by step the way a person does. The book comes with a title page, a copyright page, How to play, a page that explains the levels, a title page for each level, optional solving lessons and hints, the solutions with page numbers, optional progress pages, a thank-you page, and the exact page size and margins KDP expects. It also exports a printable edition for Etsy or your own shop, page images for your listings, and hands the book to Covers for the cover.
