how old do you have to be to play roulette?

21 any gambling

I believe the age is 18 to get on the floor. I also believe if you can get on the floor you can bet. If you question this, the best way would be to call before you go.

21 for table games such as roulette n, black jack jist to name a few. 18 for machines

i believe its 18

21 for ANY TABLE OR SLOT.... However I believe for the recently new law allowing sports betting, I think that is 18 to wager
