How do I update the game on iOS?
Check the App Store app to see if any updates are available. For every available update, you'll see a number appear in red on the top right corner of the App Store icon. Open the App Store app to choose which updates you'd like to install. If an update for the game doesn't appear in the App Store application, then it has already been installed.
