Overall good but the updates have made the awards nearly inaccessable. I asked the company what givesand they said that its due to consumers memory issues. I dont buy that! Ive got a bottom-of-the-line, obsolete-by-3-years phone, and I never had an issue with the app. Gameplay is good and keeps the mind sharp which is why Im giving them 2 stars. But its not worth the ads that come up and thus I havent played it in a couple months just so I dont give them money by watching ads.
