The player is betting that one of six numbers will come up. Bets are placed on the intersection of the two lines of three numbers. The three outside bets are outside of the 00,0 and 1-36 playing area. Bets are paid from the outside in. The dealer will pay the bets furthest away from him and work in, until he gets to the inside bets which are paid last.
Some casinos use the en prison rule when a zero or double zero occurs.
The player has a 1 in 37 chance of winning and still gets paid 35 to 1. The procedures at the European table are slightly different than the American game. While American dealers sweep the layout with their hands and arms, European croupiers use a long stick known as the rake to sweep in all bets. In Europe, roulette games do not use the non-value chips. All players use the standard casino chips, which can cause great confusion when there are a multitude of bets on the layout.
