Best Sudoku Experience

I tried a handful of sudoku apps and found this one to have the best combination of supporting speedy play, clearly highlighting relevant numbers without giving away solutions, and providing clear hints to help players improve.

Devs I do have one request – the fact that Nightmare difficult puzzles sometimes require hints that simply fill in the correct value for a call makes it hard for me to feel like I can work on those puzzles logically since I can’t think through how those are calculated, so if there’s some way to show the underlying logic there it would be much appreciated. Thank you for adding the difficulty setting though!

Great app- tiny glitch happening today

I love this app and the fact that it teaches strategy when you are stuck. I have improved so much!
Today tho, the screen went black while I was playing, all i could see is the icon for the ad at the bottom. I’ve restarted the app and restarted my phone and it’s still happening shortly after i open the puzzle. Is this a known issue? It appears to happen every time the “wizard of oz” app ad comes on the bottom of the screen.

Developer Response ,

If you encounter the same issue again, please kindly click that ad and track which game it is, and then send the screenshot to We will immediately block that ad. Sorry again! Thank you so much for your kind support! We will continue to optimize our app and deliver a better and better user experience. :-) - Cathy

Great app, minor bugs

This game is great! It keeps my mind sharp and I even got my parents playing it to keep theirs sharp as well, my only frustration is 1) the 3 and done rule is kind of small especially when you have older people with big fingers cause mistakes happen. I feel like it should be maybe 4 or 5 mistakes before you have to restart or watch an ad, which brings me to frustration 2) multiple times while playing I’ll use the free ad to continue if I make too many “mistakes” and yet I still get restarted with all my progress gone, other than that great app, just wish the bugs were fixed :)
