Log out of your game.
Close the app.
Pull up the app manager and swipe the game away.
Turn OFF your device. As in: Hold the power button until it asks to shut down, then do whatever it is you need to do to shut down. No, don't Restart - Turn it OFF.
Now go get a cup of coffee or something that takes a minute.
