Roulette odds

What every player must understand when he or she is playing any type of casino game is the winning odds. The chances to win at roulette are directly related to the wheel (American or European/French) and the type of bet. As a matter of fact, it’s quite simple to calculate odds in this game. It is even simpler to do this with the odds chart. In this way, you can easily calculate these odds and make a sound decision about the type of bet you should opt for in any situation.

Now let’s see what some of the things that you can expect when you start playing online roulette are.

To start with, an ordinary game of roulette allows players to use three even money bets – odd and even, red and black and low and high. We don’t have to talk much about the odd and even and the red and black because you can easily understand when you can win. On the other hand, you should know that low and high bets are related to the landing numbers. If the ball ends up on a number between 1 and 18 then your low bet is a winner. High bets are winning bets when the ball lands on numbers between 19 and 36. In case the ball lands on zero, you will lose your low or high bet.

In cases of even money bet (red and black for example), participants will win in case the ball lands on some of the 18 pockets that have the color they’ve selected. So, the winning odds are 18:38. In other words, there is a 47.37% chance of winning. This means that you could possibly lose 52.63% of the bets.

The calculation is simple:

0.4737 – 0.5263 – -0.0526 which means 5.26%. This is the house edge.

But, the calculations are more difficult when it comes to other types of bets like betting on one number for example. In this case, a winning bet pays 35:1. So, the player can win only if the ball lands on the exact number. The odds are 1:38 or 2.63%. Additionally, a win, in this case, brings 35 units, but a loss will take just one unit away.

Here’s the calculation:

(0.0263 * 35) – 0.9737

0.9211 – 0.9737 = – 0.0526 which means 5.26. This is the house edge.

The payouts and odds may be different on roulette bets of a different kind, but the house edge remains the same. Most casino games require adequate strategy to increase the odds, but that’s not the case with roulette. No matter how you play, the odds remain the same – all you have to do is keep playing.

As we said before, American roulette comes with a double zero, zero and 36 ordinary numbers. So, there are 38 different spaces where the ball can land. If you place a bet on one number, you’ll get 1:38 chance of winning. In other words, you can win one time in 38 spins. We have created a table to highlight the possible outcomes

Keep in mind that these odds are calculated for the American roulette. As we said before, the European version of this game doesn’t have a double zero and that’s why it’s a little bit more in favor of players.

European Roulette odds

When it comes to European roulette, the 00 pocket is missing which gives the players better winning odds. For instance, for every dollar you place on European roulette you can expect to get 97.37 cents over some period of time (that’s one dollar minus the casino edge of 2.63%). On the other hand, you can expect to get back just 94.74 cents for every dollar you invest in American roulette.

If you are looking for the bets you should avoid in this type of roulette, experts would advise avoiding single numbers and the 5-number bet (American roulette). These bets have a huge gap between odds and payouts.

In case you want to play online roulette of any kind, select the bets with odds that are more or less same as their payouts. The so-called even money bets are betting on odd, even, high and low numbers, black or red. They come with a 1:1 payout ratio.
