I'm not a gambler.. Tennesse has a Lottery, but I have never ever purchased a lottery ticket..
My husband used to place bets on Football, the Kentucky Derby, World Series, and Bowl Games, from time to time, but to my knowledge it was never a large sum of money. I do recall hearing stories about several 'bookies' in the Chattanooga area though, so there has to be some gambling going on here in Choo Choo Town..
I wasn't even aware of there being any Casinos in Chattanooga, but the link posted below claims there are several hotels here in the city that do provide gambling...
ETA...
I have always thought Casinos had to be on the water or on an Indian Reservation. Live and Learn...JMHO

If you are going to Tennessee just for gambling it is good to know that the most number of casinos are in city of Chattanooga. There are some casino hotels in Chattanooga which are very nice for its visit and stay. Chattanooga is a well known travel destination, but people who enjoy playing casino games and traveling, mostly know about this town. Chattanooga is located in the southern east part of Tennessee near the border of Georgia. While you are in this lovely town you can visit Tennessee Aquarium, the African American Museum and Civil War Battlefield sites.
