ANDROID users, leave now. Game is so buggy. Rarely loads. I created a shortcut to homescreen to force stop game many times a day. New builds does not recognize my kills. I've complained with zero response and zero consolation for missing out on "rewards". Please. Should be a relaxing experience. Can't win duels without extras. Only get extras if you win events which require duels to get extras, blah blah. If you really want to play this game, spend lots of money and don't use an Android.
