If you are a believer in ONLY betting on casino games that offer a 2% house advantage or less, then Roulette is not the game for you. Single zero wheels have a 2.70% house edge and they almost double to 5.26% on a double zero wheel.
The first 5 bet on a double zero wheel, betting the 0,00,1,2,3- has over a 7% house edge. It is by far the worst bet on a roulette table.
Other than that, have fun playing roulette and play to your heart's content. Keep you sessions short so you may have a better chance at walking away from the table as a winner.
