Outside and Inside American Roulette Bets

American Roulette Odds and Probabilities - Bodog Casino

American Roulette is one of the easiest and most relaxing games to play in a casino. You’re not up against a dealer or other players; you’re simply betting on the outcome of a spin.

Although there’s no true strategy for roulette, it helps to know what the odds and probabilities are for each of your betting options. The house edge is the same for almost all bets, but probabilities and payouts vary quite a bit. We’ll go over each bet’s win probability and payout, starting with the bets that have the highest odds of winning.

 

Outside Bets

Odd/Even        47.37%

There are 18 odd numbers and 18 even numbers on the roulette wheel. If you divide 18 by 38 (the number of slots on an American Roulette wheel), you get the win probability, which is 47.37%. The payout is even money.

Black/Red                    47.37%

Just like with the Odd/Even bet, there are 18 black numbers and 18 red numbers, giving us a 47.37% win probability. Black/Red wins pay 1:1.

1-18/19-36                  47.37%

Near the bottom of the roulette betting layout, there are two squares; one says 1-18 and the other says 19-36. Each group comprises 18 numbers, making the probability 47.37%.

1st, 2nd, and 3rd 12        31.58%

The 1st 12, 2nd 12, and 3rd 12 are popular roulette bets, as they offer more than an even money payout without incurring the higher risk of the inside bets. Their win probability is 31.58% with a 2:1 payout.    

 

Inside Bets

Any bets within the black, red and green betting layout is an inside bet. These bets consist of smaller groups of numbers, which means higher risk and higher reward.

Line Bet                       15.79%

Line bets comprise six numbers (two neighbouring lines). For example, betting 1-2-3-4-5-6 would be a line bet. They pay 5:1.

First Five                      13.16%

Remember when we said the house edge is the same for almost all bets? The lone exception is the First Five bet. This consists of betting on numbers 0-00-1-2-3 for a 6:1 payout. The house edge on this is 7.89% instead of the standard 5.26%.

Corner                         10.53%

Betting on four numbers that create a square is a corner bet. They have a 10.53% chance of hitting, regardless of which corner you pick. Corner bets pay 8:1.

Street                          7.89%

Three numbers that sit one on top of the other can be bet on together as a Street bet. The odds for a Street bet winning is 7.89%, and the payout is 11:1.

Split                             5.26%

Betting on two neighbouring numbers is called a Split bet. The likelihood of your Split bet winning is 5.26%. Payouts are 17:1.

Single Number                        2.63%
 

The riskiest bet at the roulette table is a Single Number bet. If your lucky number pans out, you’re looking at a 35:1 payout. The win probability is 2.63%.

Now that you know the full spectrum of roulette bets, along with probabilities and payouts, you can select the bets that reflect your gambling style.
