I'm quite a fan of Warcraft, therefore, obvious that I wanted to try Hearthstone. From the game itself, I am absolutely convinced, however, the Amazon app has yet to make a fundamental error of the game hardly more than 10 minutes to play. Namely, the app is not in a position at a short loss of connection an reconnect perform. However, it is not written "lost connection", but the game freezes just one. Once that happens can only be helped by a hard reset the app or you log in the AppStore from (this works, oddly enough). Then log back in and start a new game because the old one was automatically lost ... takes time and nerves. Especially when you have the fights arena makes for combat certain costs, which can not be got back. Conclusion: class game but is still waiting for something with this app. The PC or Mac version is much more stable and reliable.
