Yea. Most of these casinos offers some promotions, that's what it's called to new users so that they can check out with a little experience the casinos and also be able to decide if they will love to stay.. every casino has different style ranging from bonus, free bet, free spins and many others. There are lots of casino that offers such here on the forum but you might have to check them out on your own. Also you should be concerned about their terms just so you don't end up breaking any rules required to qualify for some major bonus...
