Occasionally, the game may not launch at all, get stuck in a particular screen, or even crash completely. This may happen due to a bug in the app, or for no particular reason at all in certain circumstances. If the game is failing for no apparent reason, try one of the following:
Update the app: Make sure you have the latest update installed from the App Store.
Reboot your device: Switch your iOS device off, restart it, and try restarting the game.
