Well there are sites that will give you a real money bonus and you don't have to deposit anything.  But I suggest that you just avoid online gambling all together.  It's too easy to get caught up in.  I'm lucky that I haven't lost anything and quit before that happened.

The offers of "free" money is there just to get you started so that you will acquire a taste for it and their hope is you'll start dropping your own money at their site.  It sucks!

Unhappy former gambler.
