This app is pretty good. However, it always downloads and installs, but it seems to have a difficult time opening some days. Some times 2-3 days in a row. It's very frustrating. So, I wind up spending my $$ elsewhere. Generally, when it does open, my gaming allowance is already depleted. I don't know if the problem is Google or belka, but I'm currently seeking out other options for my gaming experiences. I game for enjoyment, not frustration and anxiety.
