DoubleU casino

hello guys, is there a way to get free credits on this game, or not? have searched threads and cant find anything, some of my friends have billions of credits, so was wondering how they got them, either hack, or sold their house :)
many thanks

in a word no but there are glitches around that can and do give better spin rewards and so on i personally only know of 1 way and its apart of a vip tool so it will cost to get it i dont use it but i know that it works
