Having tried a few sudoku apps, I settled on this one because it just works, and works well. A great feature of this app is the hints. A great way of learning some of the advanced techniques for solving sudoku puzzles. My favourite feature is being able to scan in puzzles from newspapers etc. Glad to see the check icon is back as an option instead of the pop-up message, so back up to 5 stars. I've tried other Sudoku apps and haven't found one to match this one.

In the next update the popup will be customizable under Settings – Look and Feel. If you don't at least consent to non-personalized ads the app will keep nagging you. This is an ad-supported app, I hope you understand.

Brilliant app. Everything that I want, and great tutorials to really push your knowledge. Really well thought out app design and the only one I'll now need. The only note is that one selects the number first and then the placement, vs other apps which have it the other way around - not a problem but an initial adjustment

This app is good, but it could be so much better. When solving, it should be possible to select digits directly from the grid. That alone would double the solving . For setting, it has the advantage that it indicates redundant givens, which is very useful. Alas, though, it doesn't grade puzzles, let alone show the techniques they feature. All in all, a mixed bag.
