Roulette certainly needs no introduction. It is the most popular gambling game ever and you can play it in virtually all classic and online casinos. Roulette is among pure gambling games because it’s mainly a game of chance. Although there are various roulette systems and strategies that try to reduce the importance of luck and increase your chances of winning, in the long run, betting odds are always to your detriment. That, however, should not prevent you from enjoying the game of roulette royally.

Is not exactly clear when and how roulette as such was created. The only thing known with certainty is that the first records about roulette as a gambling game come from the first half of the 18th century from France. Since its inception, roulette has gone a long way and is now known and popular around the world.

Nowadays, we recognize two types of roulette. First, there is the traditional European roulette with one green zero. The other one you can find is the American roulette with two zeroes. Even though the difference may seem insignificant at first, this turns out not to be the case. One extra pocket – and especially a zero – greatly effects the casino’s advantage and, in turn, payouts and probability.

  • House edge for American Roulette – 5.26%
  • House edge for European Roulette – 2.7%

Learn the Roulette Rules and Winning Probabilities

Take a good look at the rules of roulette. This is important for all gambling and roulette in particular because virtually the only way you can influence your winnings is by choosing which pocket you bet on. You can then reduce or increase your winning chance by the number and type of bets. Calculating the probabilities in a game roulette is not at all difficult. All you need is elementary school level math knowledge.

You should know your betting options and their respective payouts.

Bet Payout European Roulette American Roulette
Red/Black 1:1 48,65 % 47,37 %
Even/Odd 1:1 48,65 % 47,37 %
Low/High 1:1 48,65 % 47,37 %
Dozen 2:1 32,43 % 32,58 %
Columm 2:1 32,43 % 31,58 %
Six line 5:1 16,22 % 15,79 %
Corner 8:1 10,81 % 10,63 %
Street 11:1 8,11 % 7,89 %
Split 17:1 5,41 % 5,26 %
Straight 35:1 2,70 % 2,63 %

Every basic roulette bet covers a certain number of playing fields. Logically, then, the more fields the single bet covers, the higher are the chances of winning. The probability is simply calculated by the formula:

Number of covered fields / 37 * 100

Statistically, the best bets at roulette are even bets (colour, even x, odd, high x low) which cover less than half of the roulette. Chances of winning with them are 48.65% (18/37 * 100). The least sure is betting on individual numbers. These bets have only 2.7% (1/37 * 100) chance to win.

Calculating the probability of winning for consecutive bets

Now when we already have calculated the odds for individual bets, we can further calculate the chances of winning in the series of games. For this case, the original formula has to be modified:

Probability formula for winning in roulette

Q – Number of covered fields

N – Number of played rounds

For our simulation of all individual bets, we have chosen a limit of 50 game rounds, which corresponds, on average, to one hour of roulette playing at a table of 4 or 5 players.

The probability of at least one win in 50 consecutive games

Probability roulette rounds

In the chart above you can see how the probability of winning for individual bets increases. At this point, it is very important to say that the chances never reach 100% probability.

In addition, if you are actually sitting at a roulette table, the chances of winning a single bet always depend on the probability calculation of individual bets. This means that the chance of winning a red bet will always be 48.65%, regardless of the previous one. Do not forget that this calculation tracks the game series as a whole.

You can see it clearly on the famous Monte Carlo example in 19137 when black hit 26 times in a row. The probability of this phenomenon is 0.000000007%. If we convert this number into a meaningful figure, it turns out that you would have to experience about 143 million series of 26 games to see it again, which would take about 10 000 years of consecutive play.
