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 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.

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! 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.

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....

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.

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.

It does its job without needing to know what colour underwear you have on.

Great game. Great hints for learning techniques. Removed a star because the analyse menu is no longer available on some devices (galaxy tab with Jellybean) after a recent upgrade.

Love it!

And that was until I updated to Marshmallow. Any chance to support Android 6.0.1 anytime soon?

Loved this version. Worth the money. I do have one gripe. When playing the color mode, the highlight hides the color

I've recently switched back iPhone. However, I keep my old HTC One m8 handy to play this game. I really wish the developers would release this on iOS. I've bought over a dozen sudoku games on iPhone and none of them come close to this one.

Switched from my trusty nexus 7 to a nexus 9 and this game stopped functioning. I can start the app and choose a new game but then nothing happens. I am stuck in the main menu screen. Edit: the solution worked!

Great layout, great way to pass the time, great game! Awesome! Thank you

Nice design and options. Everything needed to make a good time occur for hours.

Does what it says!

Great playability. Fantastic hint engine (really a master trainer). Endless offline games.

Of all the Android Sudoku apps I've tried this one has the nicest and most customizable interface. I really like the Analysis feature which calculates the difficulty of a puzzle and tells you the techniques required to solve it. The hint system itself is also excellent. This feels like a smart, highly polished app.

The plus version is worth the nominal fee to get rid of the ads. extensive help files help you master the many tools/settings that are a great help solving the tougher puzzles.
