One of the better Sudoku apps out there!

I must have downloaded over a dozen Sudoku apps, and this is definitely one of the better ones. I emailed the developer with some suggestions to improve the app, and he responded right away. He’s constantly updating the app with new features which is great! Keep up the good work!

Developer Response ,

Thank you so much for your review, Ibergu! Like you, I tried many sudoku games but couldn't find one that fully satisfied me. That's exactly what motivated me to create my own.
It's really rewarding to hear that you appreciate the app and the updates. Your feedback and suggestions have been invaluable in this journey. I'm committed to continuously improving Hi Sudoku to enhance your experience.
Happy solving, and stay tuned for more exciting features!

Nice Sudoku

I really enjoy the number pad of this game. The feature where you can long-press a number to highlight is brilliant. The hints are also quite helpful, teaching me a few advanced techniques.
