Addictively fun but super buggy! Especially the ads. About half the ads freeze but the rest works fine. I have now watched over ten dozen ads for which I am still owed the rewards because I was told in the app I would get the rewards if I watched the ads. I hope I'm going to be given the rewards and not left wondering if the developers are paid for the add views whether they deliver the Rewards or not. Update: I wound up having to uninstall it. I'm still owed the rewards & it freezes too much.
