If the casino sais that you get $5 free or maby 30 free, somethimes even more, it is realy free money, we tried it out a several casinos with a nodepositbonus, and indeed the money that you get is for free,
The casino are honest about the free money, somethimes the promotie ends, so if you com at a site and you see free money, always ask if you get it at the online chat,
Casino can give away free money because of there policy, people need a chance for free to see what it's al about before depositing money into there account,
So there are a lot of casinos where you can try the slot games with the free bonus, you do not have to deposit before or after you use your free money,
if you lose your free money, it's your own choise if you want to deposit and play some more..
