What you don't know is many new online casinos offer new users free spins on slots like you wanted but you still need to male deposit and do some spinning, it is no more free to earn spins and win money and still withdraw, which I believe is very wrong, this will kill their business in no time.

Some people will even intentionally start spamming the casinos for free spins to make money and abandon the casino right after, to be truthful, I don't give face to free spins anymore, they are too complicated, not entirely free like newbies think, there are some criteria in place, the only way to find out is trying yourself.
