About SudokuVariants

Hello! I'm Milan, the creator of SudokuVariants. I started working on this project in April 2021, spending some of my free weekends and afternoons to build a platform where Sudoku enthusiasts can explore different variations of the classic puzzle.

SudokuVariants is a passion project, not a commercial website. My goal is to provide a space for people who love Sudoku as much as I do to enjoy and challenge themselves with interesting variations. Whether you're here to pass the time or to test your skills, I hope you find something that excites you.

Please note that SudokuVariants is intended for personal use only. I kindly ask that you do not use it for any commercial purposes.

If you have any questions, suggestions, or just want to say hi, feel free to reach out to me through the contact page. I'd love to hear from you!
