Roulette Magic Numbers

  

Single zero roulette wheel (38×38=1,444 on a double zero wheel) or electronic or Televised Roulette games which includes Betting Shop machines and on-line roulette. Important Note:This needs to be checked by your own collection of numbers taken at random but in date order with not too many spins taken from the same machine or table at any one. Seven is a number of complement and is considered a Divine number. Seven days in a week, seven colors to the rainbow. The occult will also use this number 7, but their favorite numbers are 11 and 6. The occult avoids using the numbers and multiplications of 4, 8, 10, and 12, unless they correlate with their numbers.

Do you have a lucky number? We have several. Do they drop in for us on the roulette table? Well, we like to think they do, but to be honest, we have never done a scientific analysis of it.

Numbers play an important part in all cultures. In the west, the number 7 is lucky and the number 13 is seen as unlucky, for example, whereas in Chinese cities, buildings often don’t have a fourth floor as that number is seen as unlucky. The roulette number 8, in contrast, is seen as very lucky in China. Numbers that add up to 8 like the number 26 are also seen as lucky (it also sounds a bit like “easy profitable” in Cantonese.)

That’s what this section is all about. We are going to run though all of the numbers on a roulette wheel (bear with us, there are 37 of them), and we’ll explore whether the number has any specific meaning in different cultures and we’ll list some interesting facts and stories associated with it.

Is this one of those roulette tips that will help you pick a winner on a single number bet? Well, no, but it’ll be fun anyway. And it might help you pick the number. Who knows? It might be the winner, but we’re not going to claim any credit for it even though we are a bit superstitious.

Numbers have long held a fascination for cultures around the world. They seem to be the building blocks of the universe and somewhere in there is the answer to that age old question “what makes the universe tick?”

Numbers are not numerals by the way. Numerals are symbols used to represent numbers.

So the Romans, for example, used “V” for 5 and “X” for 10. Natural numbers (numbers that you use for counting) are the ones you’ll find on a roulette wheel. For most of history, the natural numbers began with 1 and then in the 19th century, mathematicians included 0. 00 has never been used in maths by the way!

The Main Types of Numbers

Please bear in mind that the roulette odds of all the numbers on the wheel are the same. We are not suggesting otherwise as they all take up the same amount of space on the wheel (well, if the wheel is biased or is imperfect they may not all be equal, but the difference will be very very small). That being said, let’s continue…..

Mathematicians talk of integers, which are whole numbers (not fractions) that can be positive, negative, or zero. So all of the numbers in roulette are integers, apart from the 00 which is a special that you only see in roulette.

One of the most popular bets on the roulette wheel is the even/odd bet, an outside even money bet. And this is one of the main classifications of numbers generally. An even number is can be divided two to give a natural number (i.e. one that is not a fraction or does not have a decimal point- which would be a real number). The rest are odd numbers. 0 is a special case of course. Actually, it is not really. It passes the even number test easily- so it is even. (I guess we get confused due to history. The Greeks didn’t even consider that 0 was a number).

Any number that can be split into 2 to make another whole number is even. If you halve zero, you get zero, so it passes this test.
Also, the neighbours of even numbers have odd numbers either side of them. Zero also passes this one – minus one and one sit either side of it.

Prime Numbers

A quick video from the Khan Academy explaining Prime Numbers.

A prime number is an integer greater than 1 that you cannot make by multiplying together two smaller whole numbers. Prime numbers have fascinated people for thousands of years.

As the Khan Academy says, prime numbers have been studied by mathematicians and mystics for a long time. They are both basic and mysterious. The more you learn about them, the more you discover that the universe is a fascinating place. The video above is from the Khan Academy and is an introduction to the magic of prime numbers.

The following is a list of the prime numbers on a roulette wheel: 2, 3, 5, 7, 9, 11, 13, 17, 19, 23, 29, 31. Here is a list of the first 1000 prime numbers– it might give you some inspiration on those straight up bets!

They are often popular roulette bets, as they are seen as “magic” numbers, but of course that may be just hocus-pocus. The lucky number 17, in particular, has featured in some pretty famous roulette bets such as Mike Ashley’s £1.3 million roulette win on a single spin.

Roulette Magic Numbers

There are many other interesting sub-sets of numbers, including Fibonacci numbers (which forms the base of a famous roulette system) and perfect numbers. A prefect number hat is a perfect number?

A perfect number is a whole number, (greater than zero) that you can make by adding up all the factors of the number. (Factors are numbers you multiply together to get that number, so the factors of 6 are 1,2,3 and 6.

!+2+3 = 6, so 6 is a perfect number as you can make it by adding together all of its factors.
28 is also a perfect number as it’s factors are 1, 2, 4, 7, 14 and 28. Add together its factors lower than the actual number and you get 28.

So on a roulette wheel, there are 2 perfect numbers, 6 and 28. Incidentally, some people avoid these numbers because they superstitiously believe that to be that perfect is somehow unlucky. And 6 is seen as unlucky anyway in some cultures, due to religious reasons, but more on that later.

Interesting, hey? I bet you never knew that mathematics could be so fun! Especially if it helps you find your winning number. We hope we find your lucky roulette number!
1 + 2 + 4 + 7 + 14 = 28

Introduction

The Gambler's Fallacy is the mistaken belief that if an independent event has not happened in a long time, then it becomes overdue and more likely. It is also equally incorrect that if an outcome has happened a disproportionate number of times lately, compared to statistical expectations, then it becomes overheated and less likely to occur the next time. An example of this fallacious thinking might be that if the number 23 hasn't been drawn in a 6-49 lottery the last 100 games, then it becomes more likely to be drawn during the next drawing.

Many worthless betting strategies and systems are based on belief in the Gambler's Fallacy. I got the idea for writing about this after reading an 888 online roulette article by Frank Scoblete entitled How to Take Advantage of Roulette Hot Spots. In that article, Scoblete recommends taking a count of each outcome for 3,700 spins in single-zero roulette and 3,800 spins in double-zero roulette in the hunt for 'hot numbers.' Never mind that this would take about 100 hours to make this many observations, assuming the industry standard of 38 spins per hour.

Before going further, let me say that I strongly believe modern roulette wheels made by top brands like Cammegh are extremely precise and any bias would be minuscule compared to the house advantage. Thus, testing a modern roulette for bias would be a total waste of time. Now, testing a 30-year-old hand-me-down wheel in a banana republic might be another story. However, you're on your own if you win a lot of money from said casino and try to leave with it.

Magic

That said, if you track 3,800 outcomes in single-zero roulette, the average number of times any number will hit is 3800/38=100. I ran a simulation of over 1.3 trillion spins, counting how many times each number was hit, sorting the outcomes to find the most frequent number and how many times it was observed, and keeping a count of how many times the most frequent number in each simulation was seen.

Hottest Number in 3,800 Spins of Double-Zero Roulette

As a former actuary, I hate to use a layman's term like the 'hottest number,' but that is how gamblers talk so will go with that. That said, following are the results of the count of the hottest number in millions of 3800-spin simulations.

Median 121
Mode 120
90th Percentile 128
95th Percentile 131
99th Percentile 136
99.9th Percentile 142

Here is what the table above means in plain simple English.

Roulette magic numbers online
  • The mean, or average, count of the hottest number is 122.02.
  • The median count of the most frequent number is 121. This means that over 50% of time the most frequent number appeared 121 times or less, as well as 121 times or more. This is possible because the probability of 121 observations is in both groups.
  • The mode, or most count of the hottest number is 120, which happens 8.29% of the time.
  • The 90th percentile is the smallest number such that the probability the count of the hottest number is at least 90% .
  • The 95th percentile is the smallest number such that the probability the count of the hottest number is at least 95%.
  • The 99th percentile is the smallest number such that the probability the count of the hottest number is at least 99%.
  • The 99.9th percentile is the smallest number such that the probability the count of the hottest number is at least 99.9%.

Hottest Number in 3,700 Spins of Single-Zero Roulette

The results are very similar with 3,700 spins tracked on a single-zero wheel. Following is a summary of the results.

The following table shows the full results of the simulation on both wheels. The two commulative columns show the probability that the count of the hottest number is the number on the left column or more. For example, the probability the hottest number in 3,700 spins of single-zero roulette is 130 or more is 0.072044.

Count of the Hottest Numbers in 300 Spins in Double-Zero Roulette

What if you don't want to spend 100 hours gathering data on a single wheel? Some casinos are kind enough to give you, on a silver platter, the number of times in the last 300 spins the four 'hottest' and 'coolest' numbers occurred. The image at the top of the page shows an example taken on a double-zero wheel at the Venetian.

In 300 spins, the average number of wins on a double-zero wheel for any number is 300/38=7.9. As you can see from the image above, the four hottest numbers were 20, 5, 29, and 2, which occurred 15, 14, 13, and 12 times respectively. Is this unusual? No. In a simulation of over 80 billion spins, the most frequent number, in 300-spin experiments, appeared most frequently at 14 times with a probability of 27.4%. The most likely total of the second, third, and fourth most frequent numbers was 13, 12, and 12 times respectively, with probabilities of 37.9%, 46.5%, and 45.8%. So the results of the 'hottest' numbers in the image above were a little more flat than average.

The following table shows the probabilities of the four hottest numbers in 300 spins of double-zero roulette. For example, the probability the third most frequent number happens 15 times is 0.009210.

The next table shows the mean, median, and mode for the count of the first, second, third, and fourth coolest numbers in the 300-spin simulations of single-zero roulette.

Summary of the count of the Four Least Frequent Numbers on a Single-Zero Wheel

OrderMeanMedianMode
Least 2.77 3 3
Second Least 3.62 4 4
Third Least 4.15 4 4
Fourth Least 4.56 5 5

The least I hope you have learned from this article is it is to be expected that certain numbers will come up more than others. To put it in other words, it is natural that some numbers will be 'hot' and some 'cool.' In fact, such differences from the mean are highly predictable. Unfortunately, for roulette players, we don't know which numbers will be 'hot,' just that some of them almost certainly will be. I would also like to emphasize, contrary to the Gambler's Fallacy, that on a fair roulette wheel that every number is equally likely every spin and it makes no difference what has happened in the past.

Finally, it should not be interpreted that we give an endorsement to the 888 Casino, which we linked to earlier. I am very bothered by this rule in their rule 6.2.B. Before getting to that, let me preface with a quote from rule 6.1, which I'm fine with.

'If we reasonably determine that you are engaging in or have engaged in fraudulent or unlawful activity or conducted any prohibited transaction (including money laundering) under the laws of any jurisdiction that applies to you (examples of which are set out at section 6.2 below), any such act will be considered as a material breach of this User Agreement by you. In such case we may close your account and terminate the User Agreement in accordance with section 14 below and we are under no obligation to refund to you any deposits, winnings or funds in your account.' -- Rule 6.1

Let's go further now:

Roulette

The following are some examples of 'fraudulent or unlawful activity' -- Rule 6.2

Next, here is one of many examples listed as rule 6.2.B

'Unfair Betting Techniques: Utilising any recognised betting techniques to circumvent the standard house edge in our games, which includes but is not limited to martingale betting strategies, card counting as well as low risk betting in roulette such as betting on red/black in equal amounts.' -- Rule 6.2.B

Let me make it perfectly clear that all betting systems, including the Martingale, not only can't circumvent the house edge, they can't even dent it. It is very mathematically ignorant on the part of the casino to fear any betting system. Why would any player trust this casino when the casino can seize all their money under the reason that the player was using a betting system? Any form of betting could be called a betting system, including flat betting. Casino 888 normally has a pretty good reputation, so I'm surprised they would lower themselves to this kind of rogue rule.
