As a senior, doctors said, "try new things," ie Games, music, etc. to spark and re-route brain cells. This Suduko is part of a 3 or 4 game self-challenge I use to check speed, problem solving & comprehension. I like this iphone Suduko better than the other app I tried. Timing and thinking have to do with whether I'm ill or not, and what effect medication change has on my brain. Also, the games are FUN❗️
It's been a bit of adjustment for my ego to realize I may never get the speed of the players younger and healthier than I am, when I make comparisons. I have played against myself and love to see the improvement.
I also like the difficulty options, according to the needs of my condition.
I'm impressed with the people who create the programs for these games. You are all probably the age of my grandsons, approaching 30 years of age.
Thanks, SandyB 👩🏼/👵🏼 🐬👍🏼

Hi SandyB! Thank you so much for such an awesome feedback! So happy to hear that you like our app :) Enjoy playing!

Great features! Great app support!


I love this app's customization features. You can toggle features such as highlighting duplicates, or every one of a number, auto correct, etc. So when I play I turn most of them off, but when I hand my phone to a child we turn most of them back on. It really helps to customize the level of difficulty and make the experience exactly what you would like it to be.

Also, their support is amazing! There was one pop up ad that was hijacking the app and driving me nuts. I was going to give it a bad review, but noticed some reviews said they received a response from support and thought I'd try it too. Within 24 hours of contacting them I received an email telling me they blocked the annoying ad. And they did!

Unbearable ads play sound while phone is muted


I have been using this app daily for several months now, and have really enjoyed it. BUT I RECOMMEND THAT YOU DON’T INSTALL IT. Just recently it has started serving up ads to me that blast sound EVEN THOUGH I HAVE THE AUDIO SWITCH TURNED OFF ON MY PHONE. It shows a complete lack of respect for their users that this company engages in this practice. If my sound is turned off, it’s because I don’t want my phone to make noise! To have an ad come blasting out of it all of a sudden — and often with NO WAY TO STOP IT — is embarrassing to me and rude to those around me. I reported the problem to them, and sent screen shots and the time and date it happened three times, at their request. But clearly they believe that allowing it to continue will somehow benefit their advertisers. I have deleted the app and won’t reinstall it, or any other products from this company. One of the most infuriating things I’ve ever experienced with an app.

Hi! Thanks for your feedback. Sorry to hear about that! We are working hard now to fix this issue with ads sound in the app. For now we are working to reveal the problem advertiser and hope send them the complaint. Sorry again for this inconvenience.
