Facebook is needed if you play on Android. If you are on an Apple device, you use Game Center.

There are a couple of things to help you on Rainbow (but there are a lot of combos and you do have to "hope it works"). Users enter successful combos on the Epic Dragon Breeding Charts page-look under the "Rainbow" tab.

You can also use the "Combo Finder" tab on the DragonVale Breeding Sandboxfor a list of all possible combinations and the failures that may result.
