Which is very good advice!  If those of you who might be looking forward to winnings off a free chip I would tell you exactly this.  Most of the RTG casinos like the Silver Oak Group, the Coolcat and others, I redeem them and look at it like play money.  At Silver Oak I redeemed a chip and a little while later had $2000 bucks!!  But coming off a free chip without depositing I wouldn't think it was cashable at all.

I only have ONE RTG casino that I deposit at, and that is Inet Bet.  I only use their free money codes when I get an email, and I have once used a match bonus on a deposit but usually I just make a straight deposit with no bonus.  I haven't been lucky enough to turn it into enough to make a cash out, but I only deposit $10 or $20 at a time!  But I plan on depositing there this week, and I have a feeling I will be cashing out some winnings!  hahaha

Yes it is almost the same as play money, if not sure talk to live chat and ask the terms and the max cashout if in case you win something!!!
