App is literally unplayable on Android 5.1.x. Downloaded it on my Xperia Z3 and it either crashes when loading into the game or let's me get into the main menu and then crashes when I select a game to load into. Have not been to play a single turn. I have an older version of Android but its not old enough that the compatability should be hard to make work. And besides if they have it available on the PlayStore for Android5 then you should be able to play it on Android5
