I got a $200 free chip in the snail mail and even after reading the stories on here I decided to try it, because, well why not? Anyway I made playthough and ended up ahead, so I checked with live chat:

I tried to ask everything possible to guarantee that I didn't violate any hidden terms. Looks like I have to decide if I want to 'gamble' a $150 deposit for the chance of getting my $500 cashout... Think it's worth it?

And just cause it's a cool shot, here's what got me to a point where I could actually make playthrough :
