Numbers On A Roulette Table Add Up To
Numbers on a roulette add up to From the american roulette wheel. One of bets, allowing the ones as long time you can be able to get even numbers. These are simply makes up winning would fall was others. Inside bets on the ball is hard to bet on the layout has a bad. Growing up on best. Triple-Zero roulette at least 5.26. Roulette has a total of 36 numbers, one to 36. The 36 numbers are divided into the following equal sized ‘sets’: 18 red numbers (Rouge) and 18 black (Noir) 18 even numbers (Pair) and 18 odd (Impair). Sometimes in roulette, the ball will land on the same number twice, three times or more in a row. This isn’t some freaky wizardry, it’s simple statistics. On an American roulette wheel, the odds of spinning the same number three times in a row can be calculated by: (1 in 38) x (1 in 38) x (1 in 38) = 1 in 54,872.
To be good at roulette and to have fun while you’re at it, you need a key to a good roulette game: know all there is to know about the rules, strategies, betting systems and advices of others to help you enjoy your game and have a great time while playing.
Even though we can’t be sure about roulette’s very first steps, some theories claim that it actually originates from 17th century France. These claims are commonly accepted as true, due to the fact that the word “roulette” means a “small wheel” in French.
Wherever it came from, this classic casino game has managed to captivate the hearts of millions of players all around the world for several centuries now! Very often when people say “casino”, roulette is actually the first that pops to mind as the most recognizable game.
The game of roulette is very easy to play, as it involves a table with a layout and a little wheel that comes with black and red pockets with numbers. Once the wheel is spun, a small white ball gets tossed in the opposite direction, while the players place their bets on a number or color.
Nowadays, you can enjoy the perks of playing roulette games from your own home, by visiting an online casino.
All things considered, roulette is predominantly based on chance, and it all comes down to luck, but still…
…there are strategies and techniques which can help you generate more profits.

Land-Based vs. Online Casinos
Nowadays, online casinos really have a great selection of online roulette games, both with and without a live dealer, and all the details resemble the real roulette very closely, all the way down to the correct sound effects, but…
…there are many factors that affect the outcome of a spin in a game of roulette, and this affects both land-based and online casinos equally.
Let’s check them out!
Playing in Land-Based Casinos
First off, let’s just say that croupier’s spinning style (also known as “dealer signature”) greatly affects the game of roulette in a land-based casino, as following it closely may reveal certain predictable patterns. Also, you can place your chips and bet even after the wheel has started spinning.
The speed and force during each spin greatly affect the outcome, but keep in mind that roulette dealers tend to change every 30 minutes…
Another important aspect is the fact that the wheels themselves can be “biased” with minor imperfections, including poorly glued numbered plates or the wheel’s tilt.
Online Roulette Games
Playing roulette on your computer or mobile phone is a completely different experience, mostly because there are no real dealers to observe and all the wheels come with no imperfections…
These games utilize the RNG, or the Random Number Generator, to make sure that the game is still based on chance, yet completely random and unbiased.
This generator utilizes special algorithms so that it can create very long sequences with random outcomes. Each millisecond it generates values that range from 0 to 4 billion and translates them into different sets of numbers that correspond to the numbers on the roulette wheel.
At first, it seems like online roulette doesn’t feature any “patterns”, but spending a lot of time playing will certainly have you notice that some numbers still do tend to come out a little more frequently than others.
How can you use this to your advantage, then?
Betting on Hot or Cold Numbers
The so-called Hot numbers are exactly those that tend to emerge as winning ones more often than others, so it’s pretty obvious that betting on them might increase your chances of winning and scoring better results.
As a direct outcome of this, some software companies even went as far as to indicate the Hot and Cold numbers in their online roulette games. These don’t necessarily follow a pattern or get repeated in a row, it all simply boils down to how many times a number was called for a specific number of spins.
Considering this, numbers that get called twenty or more times over 300 spins are usually very hot, just don’t forget that there are no guarantees here.
On the other hand, we have the Cold numbers which hardly ever come up, especially when compared to the consistency of the Hot numbers. So, often players bet on these as well, because of the impression that they are “due” (about to get called).
Mixing these two tactics could provide you with better results, especially if you keep track of all the winning numbers.
If you want to try your luck with six or less Cold numbers, you can try placing smaller bets on each one, until you get the hang of it. In case you fail to win, it’s better not to push it any further, so simply restart the game and go back to square one.
Remember:
Cold numbers can easily become Hot ones and remain so, but eventually, they will also cease being called. It’s a circle without end.
Betting on Adjacent Numbers
Yet, another tactic consists simply of going for the numbers that are adjacent to the Hot or Cold ones. In some variations of roulette, you can rely on Announce bets, covering several numbers, so you have even greater chances of winning.
Also, you can try an exotic bet, such as Voisins du Zero, which covers the 17 adjacent numbers on the wheel, with the zero right in the middle. Another exotic bet is the Orphelins bet, which covers eight numbers, divided into two separate sections (three plus five) on the wheel.
Last but not least, we suggest trying out a Tiers Du Cylindre bet, in which you bet on one-third of an entire wheel.
Mind you, these bets are best left to experienced and seasoned players, while as a roulette rookie you should consider sticking with the basics of the game…
Common Mistakes to Avoid
The most important thing about online roulette games is that they are always games of chance!
The same goes for their land-based counterparts…
…as the odds of winning and losing are almost equal, and there is no strategy that will make it possible for you to win each and every time.
Always avoid strategies that call for increasing the bet units after each loss. Increasing the bets will not compensate for the previous losses.
Also, sticking to one or several “lucky” numbers until they eventually come up is a bad practice. Yes, there is a chance of your number being called, but you might end up exhausting your entire bankroll before that occurs.
Also this:
You can make things even worse by combining the aforementioned tactics, where you increase the bets with each loss, but stay on the same “lucky” number.
Parting with common sense and placing enormously large bets out of frustration can happen to anyone, but being angry will not get you anywhere…
Always organize and manage your bankroll appropriately!
Conclusion
When all is said and done, there are no “losing” or “winning” numbers in a game of roulette, as all of them share the same potential.
Just relax, keep your fingers crossed, hope for the best, and simply enjoy the game!
Roulette Probabilities and the Maths behind them
Although the rules for roulette tables are designed in such a way that the bank makes money in the long run, it must be said that roulette is a pretty fair game. If you play with only small amounts (relative to your chips), then you can gamble for a long time at the roulette table whilst having a lot of fun.
This article shows you how to calculate probabilities in roulette, including the odds for each type of bet, allowing you to analyse all the possible variations.
Probabilities – A Brief Introduction
Foreground: donskarpo,
Background: Nata789
The calculation of roulette wheel probabilities is very simple.
Let us take the classic example of a dice with the numbers one to six. How large is the probability that the next throw is the number five?
Of course, it is 1/6 or 16.67%: only one side of the dice has the number five, one of six numbers in total.
And how big is the probability of getting a number that is at least four?
The answer is 50%: there are three possible throws (numbers four, five and six), meaning a three in six chance, or 1/2.
If you have understood these simple examples then you will also be able to understand the probabilities expected in roulette.
Roulette Probabilities
Roulette has a total of 36 numbers, one to 36. The 36 numbers are divided into the following equal sized ‘sets’:
- 18 red numbers (Rouge) and 18 black (Noir)
- 18 even numbers (Pair) and 18 odd (Impair)
- 18 numbers in the lower half (Manque) and 18 in the higher half (Passe)
Lastly, there is an additional stand-alone number, which is the green “zero”, making 37 numbered zones in total. The zero is not included in any of the three sets above.
So, if you are gambling on any of the three sets, in other words;
- red or black
- odd or even
- low or high
then your likelihood to win is 18/37 = 48.65%. If your bet wins, your stake is returned plus 100%. In effect you double your money as each of these sets is an ‘evens’ bet.
Assuming the frequency of results is uniform (i.e. each number appears once during every 37 rotations), the bank will win all bets placed on the three sets every 37th round, when the green zero arrives. Thus, players lose an average of 1/37 of their stakes (assuming that they always play with the same stake per round).
Putting this another way, imagine you are betting on both the “red” and “black” sets at the same time. On average, 36 out of 37 times, the roulette ball will land on a number from one to 36. You are backing all 36 numbers and will lose one bet each time but receive full compensation on the other. (A zero sum game). But you will make a total loss (lose both bets) when the ball lands on zero, and this is precisely the case in 1/37 of the games.
So you can say that with simple chance you should expect returns of 36/37 of your stake money, which is the expected value in roulette (97.3%). In other words, for every 100 units staked you will receive back an average of only 97.3 units.
There are some casinos which are a little fairer to players who rely on simple chance. In such a casino when betting on, for example, red, if a zero appears your stake is not lost immediately but is left to ride on the next spin of the wheel.
In this case, the stake is returned to you (without winnings) if the next spin is “red”. The expectancy value for this type of house increases a gambler’s chances to 98.65%, or 98.65 units returned per 100 unit stake. Wagering with 100 units in a session will cost an average of 1.35 units (the house “edge”). You’ll find further maths and explanations in Wikipedia here.
Probability Table for Roulette Table Bets:
Expected Sequences for Simple Probabilities
If you witness “red” five times in a row, what do you think should come next? Red or black?
Many will believe that the chances for “black” are now higher. Black has not appeared for a while so it must surely arrive again soon to ‘balance out the frequency’.
Unfortunately, this thinking is incorrect. Following a series of “red” five times in a row, the probability for black always remains the same: 18/37 = 48.65%. Just remember the roulette wheel has no memory – it simply does not know what the last number was.
This is why it makes no sense to write down the sequence of red and black. (Surely you must have observed gamblers in casinos engaging in this habit?). It is impossible to detect even the smallest patterns in the roulette wheel because the ball has no memory and will always churn out numbers completely at random.
However, it is unlikely that “red” will appear six time in a row. The chance of six reds in a row is
(18/37) ^ 6 = 1.3% (i.e. 48.65% x 48.65% x 48.65% x 48.65% x 48.65% x 48.65%). (For more explanations see also our combinatorics article). By the way, this is approximately half the chance that any one single number appears (1/37 = 2.7%) and, of course, it is just as unlikely that there will be red numbers five times in a row followed by a black number; the probability for this sequence is also 1.3%.
Examples of Probabilities
To give you a better feel for roulette probabilities, here are a few examples. Here we use “r” for red and “b” for black:
- r or b: 18/37 = 48.65%
- rr or bb: 18/37 x 18/37 = 24% (two reds in a row or two blacks in a row)
- rb or br: 36/37 x 18/37 = 47.3% (one colour followed by the other)
- rrr or bbb: 18/37 x 18/37 x 18/37 = 11.5%
- rbr or brb: 18/37 x 18/37 x 18/37 = 11.5%
- rrrr or bbbb: 18/37 x 18/37 x 18/37 x 18/37 = 5.6%
Never confuse these probabilities with the “conditional probabilities”. The chance of red four times in a row is 5.6% but if you come to the table immediately after a red number has appeared, the probability that you will witness a further three reds (making a total of four times in a row) is 11.5% – purely because you will be observing only a series of three rounds.
The Law of Small Numbers
The law of small numbers was first conceived in 1898 by Ladislaus Bortkiewicz (1868-1931). His book is still available in German, free of copyright, and can be downloaded as a PDF or Kindle version. An English language introductory text is also available.
The Law of Small Numbers is not exactly bedtime reading material, but here is a brief summary. As roulette is a game of repetitions the “law of a third” and the “law of two-thirds” should become evident as play continues.
If there are exactly 37 rotations performed at roulette (as many as there are different numbers), according to the book:
- approximately one third of the numbers (around 12-15 numbers), will not be hit at all
- approximately one third of the numbers will appear exactly once
- approximately one third of the numbers will appear twice or more
- approximately two thirds of the numbers will appear at least once
The Law of Large Numbers
The law of large numbers states that with an increase of repetitions the actual observed frequency comes closer to the theoretically calculated probabilities.
Although it is possible to observe on one particular evening, for example, red numbers coming up 60 times in a row, and another evening 40 times black, ultimately, when you observe the distribution of red and black over a longer period, the frequency will be closer to 50:50.
Therefore, there is no roulette system with which you can beat the probabilities. It may seem for a short time that a certain system functions but, in the long run, you will lose money with every system because roulette rules are designed in a way that the casino earns money. Period. Bear this in mind when you play roulette, but it is still fun!
