If you are looking for some low stakes table games in Biloxi, we found a current promotion being offered by the New Palace.
They are offering the below table games with low minimums.
$.50 roulette (Usually a $2 or $3 minimum bet but the chips are worth .50)
I also heard that Boomtown has $3 blackjack and craps, but I was not able to get 100% confirmation. If you know, please post a comment below.
