How do I transfer my games from one iPhone to another?

Launch the Google Play Store. Tap the menu icon, then tap “My apps and games.” You'll be shown a list of apps that were on your old phone. Pick the ones you want to migrate (you might not want to move brand-specific or carrier-specific apps from the old phone to the new), and download them.

Select the option “Restore from iCloud” and enter your Apple username and password. Tap “Next” and complete the process. Your game data is now transferred to your new device.
