Navuta all of the no deposit bonuses that NDN promotes on this site are legitimate. If you follow the RULES and meet the requirements, you should have no problem cashing out if you win. If you do have a problem cashing out and it is promoted by NDN. You should private message NDN with what is happening and give him your information. He will then help handle the problem. Should any problem arise. So go ahead and have a ball. Play all of them. But read the rules. Each casino has their own rules and guide lines that are to be followed and met. They are very strict on this, and allow for no exceptions!
Also I think you may have misunderstood TerpZone as I do believe he was just inquiring on if you can cash out. Not that they won't cash him out in this particular instance.Please feel free to correct me if I am wrong.
