A Comprehensive Guide to Roulette Odds

We’re back with another excellent guide for all you roulette players!

In this article, we’d like to go over different roulette odds, like the American Double-Zero Wheel, the European Single-Zero Wheel, and the roulette house edge. After that, we’re going to talk a bit about roulette payouts.

Strap in, and let’s get started!

Roulette Odds

The House Edge

Many gamblers like to say, ‘’the house always wins’’. This is so because the house cashes on a player’s loss as casinos are created to make the most profits possible. Thus, the term ‘’house edge’’ was born.

Simply put, the house edge is the advantage a casino has over all the players. Essentially, the house edge is the difference between the odds of a player winning and the casino’s payouts for a winning wager.

What About Roulette House Edge?

In roulette, players have a better chance of winning than in other casino games. Nevertheless, it’s still beneficial to familiarize yourself with the odds on roulette before betting your money. Of course, the odds can differ depending on the tables and the wheels, which we’ll discuss in greater detail below.

Gamblers can significantly improve their chances of winning by simply learning the odds on a roulette table they want to play. Unsurprisingly, the types of bets you play can give you a completely different outcome. However, you should know there are no best roulette bets, as the game is based on luck and not any particular strategies or skills.

Additionally, the house edge can vary depending on whether you’re playing on an American or European wheel.

European Wheel House Edge

There are 36 roulette numbers on a European table. However, apart from these, you can also see a green space labelled 0. This addition is the house edge. But how does that work?

Because we don’t count the 0, the players would be paid as if there were only 36 spots instead of 37. For example, if you’re wagering on black space, you’re hoping the ball will land on one of the 18 black numbers. This might seem like a 50% chance, but it isn’t! Because of the addition of the 0, you’re more likely to lose than win.

American Wheel House Edge

The house edge on the American table works in the same way, apart from the additional 00 space. Here, the roulette odds are not the best for the players because the casino is paying for only 36 spots out of 38.

To illustrate, if you place a bet on a black number here, you’re going up against 18 red numbers and an additional two green zeros. Therefore, the casino has a far more significant advantage, so you’re luck might run out quicker than you think!

Roulette Odds – European Single-Zero Wheel

We’re here to explain if you’ve ever questioned how the odds on a European roulette table work!


The best way to determine the odds is through an example. As we mentioned above, by betting on black space, you’re actually going up against 18 red spaces and one green. Therefore, instead of the expected 18:36 odds, you’re getting 18:37.


With the previous odds in mind, we can calculate the likeliness of winning at a European Single-Zero Wheel. As we said before, the probabilities here favour the house. Therefore, instead of the expected 50% chance of winning, each player gets approximately 48%.


European roulette payouts are relatively easy to understand. Chiefly, you need to grasp the premise of outside and inside bets. Outside bets have higher chances of winning with smaller payouts, while inside bets are the opposite. When betting on single numbers, payouts are 35:1. Moreover, the casino pays players 2,7% less than it should because of the edge mentioned above.

Roulette Odds – American Double-Zero Wheel

Now that we’ve explained the European Wheel, let’s go a step further and discuss the odds of roulette on an American Double-Zero Wheel.


The American wheel includes an additional 00 green space. That means the odds are even more in favour of the house. By betting on a red number, you’re going up against 18 black and 2 green numbers. Therefore, that leaves your odds at 18:38.


Similar to the European Wheel, probabilities on American roulette are calculated in the same way. Consequently, each player has around 47% chance of winning a game.


The payout of an American roulette wheel works the same way as the European one. Since it depends on the types of bets placed, inside and outside bets carry the most weight. Therefore, payouts are 35:1 here as well when betting on single numbers. Additionally, the casino pays players 5,2% less than it should.

What is The Payout on Roulette?

To get a clear picture of how payouts work, you must familiarize yourself with the different roulette bets. Although this may seem daunting because of the various bets with individual odds, it’s far from the truth.

We’ve constructed a roulette payout chart to ease your load so you’d know what to expect when making a wager. As we’ve already mentioned, the odds are not the same for the European and American Wheels. Therefore, it is essential to double-check the table you’re playing, so you know what’s in it for you.

Keep in mind that there are different kinds of outside and inside bets! The first five in our table are inside bets, the following five are outside bets, and the last is a special bet.
