5 stars: I've always like working with numbers. I think this is a really challening, relaxing and fun app (great for the brain, with many levels- from easy to expert). It has many nice features too ( gives you hints, if needed, let's you know when you've entered the incorrect answer and you're able to note possible answers, until you arrive at the correct answer).

5 stars: This is literally the cleanest app I have ever seen. The layout is perfect, and the gameplay is straightforward and straight to the point. I was even surprised when I found out that you can change the theme of the app through the settings. Overall, this app is exactly what I was looking for when I thought of downloading a Sudoku app.
