The Outside betting area is where you make bets on groups of numbers as well as Red/Black and Odd/Even. The following tutorial will show you the different outside bets you can make. The house edge on the outside bets are 5.26 for games using the double zero wheel. You cannot combine outside bets with inside bets to meet the table minimum.
