Casino issued earlier this year. However, ones for sale at cage were extremely limited. You might be able to find one in the Oriental Room -- Club Fortune just as you enter the casino and go up escalators to right. They only issued 500 so they might be out. They were selling them at player's club or perhaps they can give you information on them.
Here's one I picked up around the first day of issue.

Best poker room at the Beau Rivage-- they play $2 - $8 there with splashing the pot with $100 every time dealer flops three suited cards. Then next hand gets the cash. Big pots every hand -- especially when the pot splashes. Also, they have a better Aces cracked, etc promotions.

You can play poker at the Golden Nugget -- that's the old Isle of Capri right on the beach before the Ocean Springs Bridge and the IP has poker upstairs.

The Scarlet Pearl plays poker tournaments and you can get a schedule a week at a time so you can plan any play.
Ask the Poker Room manager if he has any card spinners left that you would like one. Will give it to you if they have any left. It's really cool. The SP is located across the Back Bay Biloxi Bridge at D'Iberville.
