Spin and faucets are not the same thing. I have used two faucets before which are freebitco and cointeply or so, you will solve captcha and earn bitcoin, but the amount earned is always small and not profitable than a water of time. Free spin are different, as faucets are targeted on people generally, free spin may be targeted in some set of people which makes the difficulty of free soon to vary, you may earn nothing from free spin, you may earn something big from free spin, you may earn big amount of money from free spin.
