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.

Thank you so much for your kind support! We will continue to optimize our app and deliver a better and better user experience. :-) - Cathy

Best app! But lots of crashes..

I just downloaded this app three days ago, and I normally never leave reviews. I love this version of sudoku, and especially that you can adjust the settings the way you want. Plus- the ads aren’t overwhelming, like most games.
However, I’m experiencing app crashes, but instead of just the app closing, my whole phone will freeze for about a minute or two and then shut off. So it’s been frustrating as I play, because after a couples minutes or so I can’t play. I’m sure it’s just a bug, that can be fixed and updated. But just to let the developers know!

Developer Response ,

Hi, sorry about this issue. Could you please kindly take a screen recording or a video regarding the whole process of the freeze issue, and send it to It would be very helpful for us to locate the issue and make the game right for you. Thank you very much for the support! :-) - Sarah

Needs a No Answers and Better Notes option

It’s a pretty good Sedoku puzzle app all around. The only things that would make it perfect would be a way to remove hints and an improved note taking system where I can write out my own details to help me solve the puzzle.

I also don’t like how it tells me if the number I put in is right or wrong. Some people like playing with this option, but I do not and prefer to find the solution on my own terms. Give me the option to disable when I am right about my input and it’ll be THE sedoku game for your phone

Developer Response ,

Hi, thank you very much for your kind support. Could you please kindly update your Sudoku to the newest version- v1.16.3? In this version, you can choose to close the mistake note reminder in the Settings. Please give it a try, and if anything, please feel free to reach us at Thanks again for your kind support! :-) - Cathy
