Oooooops! And I pride myself on attention to detail. I looked at every detail on the chips to make sure that they matched and still didn't catch the difference. I was only in the old Harrahs once before they closed and didn't collect roulettes then so I have no idea how many tables they had. It would surprise me if there were more than two given the size of the casino. I guess that this is a new chip. Unless they have move the tables in the Mardi Gras for the fifth time there should be four sets of new chips. I plan on going in the next few weeks and guess I wil be harvesting roulettes!
