If you mean differences in gameplay or game mechanics, it is absolutely identical in both types of casinos. But if I have to choose between them, I'm definitely on the side of the social casino, because there I don't have to worry about the integrity of my deposit, because it's virtual. Especially you have no downloads needed for
free classic slots and you do not have to worry about your personal data being stored in such structures, which was very reassuring for me because I am a very suspicious person by nature. So I like social casinos where different elements are spinning or I catch a fish and for the catch I get gold coins with which I can play.
