I had a $10 casino free play offer from Intertops in the mail. Catch was I had to do a $600 playthrough and it could only be in certain games i.e. slots, bingo, 3 card poker. I built it up to about $22 and then went to my game of choice. About 2 hrs later and $600 in wagers I ended up leaving with $28 of money I could do what I want with. So not a bad offer and its the second such offer I have done through them the first one though was harder as I needed to do $1000 playthrough but it was fun.
