A street bet is any roulette bet on three numbers which are found in a single horizontal line. This bet is similar to a split bet but allows you to bet on a group of three numbers instead of just two numbers.To make a street bet, you place your chips on the outside of the row you want to wager on. If you are going to bet on the 1 to 3 row, you will place your chips on the outside edge of the number 3. Street bets in roulette gambling have payouts of 11 to 1.
