But a lot of casinos has raised table minimums since they can fit fewer people at each table. When I was at harrahs Metropolis a few months ago there minimum table stakes were $15 and that was on a Wednesday afternoon. With the single zero I believe that the roulette game theoretical hold goes from 5 1/4% down to about 2 3/4%. With the slow speed of the game it could be a nice way to kill a few hours inexpensively. And the drinks are still free!
