Doesn't work! Freezes!

Ads work but app doesn't even work. Downloaded it, tried it, deleted it. Then decided to try again. Still doesn't work at all. Really disappointed!

Very well done. Fabulous Developer

The program has a variety of levels. Some are easy and some are very challenging. I love the variety. On top of that, the developer is incredibly responsive. That is very important to me. I mentioned to him that another app I was using had a feature where all the bad numbers would disappear after I selected all the correct ones. Within days that option was here. I highly recommend you try it.
