At RoyalVegas and PokerTime, you just have to create an account, then you will automatically get the 10$ after about 24 hours. You dont have to do anything else.

If you dont get the money you can still write an email to their customer support asking for it, but it wasnt necessary for me. I just downloaded their software, created a new account with my information, and after some hours I checked the 'banking' tab and saw 10$
