The game requires iOS 3.2 or later installed in order to run, but runs best with iOS 4.2 or higher. Game Center features require iOS 4.1 for iPhone or iPod touch, 4.2 for iPad.  You can update your iOS for free by connecting your iOS Device to a computer with iTunes installed, or by visiting your local Apple Store (or mobile retailer which provides your mobile service).

What should I do if the game won't start?

The most likely cause is that your device has too many background apps stored. To remove these, double tap the home button from your home screen so the background apps appear on the bottom. Press and hold any of these apps until the minus sign appears for each of them, then simply press the minus sign for each of them until they are all gone.

What should I do if I continue to experience technical difficulties?

If you are still experiencing performance issues or crashes, it may be time to cycle the power on your device and restart it to clear out your memory of applications running in the background. To do so, simply press and hold the sleep button on the top of the device and the home button at the same time for at least ten seconds. Continue to hold both buttons until the screen goes black and then comes back on with the Apple logo on screen. Once the Apple logo appears you can release the buttons. This will restart your device and clear out any problems.
