"When you played it, if you win, they swapped the NCV chip for a live chip plus paid your winning. I ended up with $675 once I had played all my free play chips. Not bad for a $250 investment. "

Happy Birthday and a nice win. I don't know if I would have played the chips. It's always a tough decision when I get them. I usually leave with them, unless they are damaged, then I play them.
