Straight Up bet is a wager on a single number. It pays 35 to 1. Split Bet is a wager on two numbers and it pays 17 to 1. You make this bet by placing your chip so it straddles the line between any two numbers. Street bets or line bet pays 11 to 1. You make this bet by placing your chip on the vertical line separating the outside and inside.
It's quite uncanny, sometimes numbers have meaning. I certainly felt that I was dancing with the devil at times when I burned thousands playing roulette.
