Can not get app to work. It opens and freezes.

I loved this app until recently. It worked fine until a month or so ago when it start. It opens and freezes before ever getting to the game. Just got an update and hoped that would fix it but did nothing. I've tried all the support tips and nothing works. Guess I'll look for another app with real support!

Well after the latest update this app is back to normal. Working very well and not freezing up. Support still could be better but they did get the bug that had it messed up fixed after a while.

The game plays great and is a nice way to relax and forget the stresses of the day. It gets only four stars because of the ads. Almost every time you open the app a sometimes long and loud ad plays first. Although it's worth playing an ad to play the game it is annoying with the long ads and the volume of some.

Hints helpful; app seems to have gotten slower

I like the hints. A while back, if you asked for a hint all the app would do is reveal one cell. Now, it offers progressive problem solving hints that help the user to improve their skills.

I do have one gripe, however. I find that the app runs much slower than in the past. I often am ready to enter my next step and find myself waiting for the app to complete registering my previous step. This slows everything down, and I cannot compete with my previously recorded best times as a result.


This is a great way to settle my brain at the end of the day or to pull up when I am waiting.
I like that you can choose the level you want to play each time, and that you can come back to a game if you are interrupted. When I am going for speed it is helpful that a set of numbers flash when you have used all 9 of them.
