How do I transfer game data iPad to iPhonePost count: 1703Reputation: 1020Joined:Location: Pittsburgh, Pennsylvania
@DragonSlayer22 On your IPad go to your Facebook app and log in. Then open your Dragon City. In the upper right corner open the settings menu (gear icon) and connect to Facebook.
Do the same on your phone. If you have to play through the tutorial, make sure that when you connect to Facebook you select the correct game and not the level 2 game because once it is connected to Facebook it cannot be undone.
