A Message from the Developer

Hey there, Sudoku fans! I've spent over two years working full-time on this game, working hard to create what I hope will be the complete Sudoku experience. My goal was simple: build a game that covers everything a Sudoku player could ever want, from casual solving to advanced analysis and even painting beautiful Sudoku images. Whether you're here to relax with a quick puzzle or dive deep into solving techniques, I've got your back. Good luck and have fun!
