SudokuGenerator 1.1.5 for Mac could be downloaded from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This software for Mac OS X is a product of Rorohiko. We recommend checking the downloaded files with any free antivirus. The application lies within Design & Photo Tools, more precisely Converters.
From the developer:
If you're publishing a newspaper, magazine, newsletter... this will enable you to generate Sudoku puzzles directly into an InDesign document - for example, for your 'Puzzle Page', or to generate whole booklets with Sudoku puzzles.
You're in control of the look and feel of the generated Sudoku - and our generator takes care of actually building the puzzles for you, straight into the final page. No more copy-paste or error-prone retyping needed!
