Couldn't find a way to set difficulty level
Well done implementation. The customizations and options are impressive
Awesome. I love this game and play it daily.
Having tried several Suduko apps from 2010 onwRds, I liked this one and upgraded to the paid, ad-free, version. I play 1-3 games every day! Love it. Oh, I might play one now....
Great app for doing Sudoku on your phone. The one drawback is that you cannot enter your own puzzles. Coloring takes a little while to master. Good input system. You can auto fill candidates and then delete as you eliminate them or you can add candidates one by one.
Great game, I would give it a 5 rating, except I found an X puzzle with an error in it, requiring numbers be doubled in a single row which means skipping some numbers entirely. As such, the puzzle has no solution. The Analyze function doesn't recognize the error in the puzzle design and quite happily tells you, yes there are two 3's in the X row. Seems there is an issue with quality control.
The app itself is ok but the default colors are awful. There's a lot of customization options which is great, but no way to save/backup so if you change from light to dark mode you lose all your choices. I do this accidentally too frequently. I wish it was just usable from the start without having to change it from the garish colors.
Great! Love the systematic hints that help learning new strategies. Please add the possibility to define own sudokus. This would allow using the app an its hints to solve sudokus from magazines, etc.
It does its job without needing to know what colour underwear you have on.
I'd like to give this app 5 stars, but the end game screen recently has developed a habit of jumping all over the place instead of staying put.
