Usually such free games creates just to test casino. If you bet real money - you can win, but when you play for free - you get just tokens that costs nothing. I can`t say about this casino, but mostly it is so.
PS. 8 months... you have amazing patience... I can`t do it even for several weeks i think.
Obviously, OP did not know this and after all that 8 months of actively doing lucky spin he is hoping to win, it's not fake it's just the probability is too high that your chances are only consolation, newbies are like this they see a spin and they hope that these free spins will give them a chance to win big, no way if you want to win big, bet with real money you'll have a good chance to win.
