Facebook used to have offers like most if not all the other games to earn free gralats through promotional offers via subscriptions to various things,filling out surveys,and my favorite downloading apps to your idevice and trying them out. Got a good free 35k or more that way. They took them down several months ago tho,and to my knowledge they where never available on the ios version of classic. The skyrider client had a similar thing as well but Idk if it still has it since I don't and will never use it again.
