Although roulette is a completely random game, people still tend to be superstitious about certain numbers. This is true whether they are in a casino or playing roulette online. Here are the most common numbers played in roulette and why.

People are superstitious, no matter how rational we normally are. We may not believe that stepping on a crack will break our mother’s back, but we probably have some minor superstitions that we cling to, like knocking on wood or having a “lucky number.”

Gambling brings out the superstition in all of us, and it’s easy to see why. For a long time, if people wanted to bet, they used to guess a number at random or go by their instincts. But people wanted to improve their chances of winning, and so the game led to the development of probability theory.

The idea of ​​probability was not codified until mathematicians Blaise Pascal (who is credited with the invention of the roulette wheel) and Pierre de Fermat formulated their theory of probability, which laid out a mathematical framework that we can use to analyze chance events. logically. The probability of an event is converted to a number that indicates the probability of that event occurring.

Yet even with this mathematical breakdown of the probability of an event occurring – like your favorite number coming up at the roulette wheel – people still insist on clinging to their gut feelings or superstitions to guide their decisions when it comes to gambling. . This is why we see the same numbers being played over and over again by so many different people.

These are some of the most common numbers you will see played at roulette and why.


If you ask any dealer what the most popular number played online is , they are sure to say 17. The 17th slot has also been the center of some amazing historic roulette wins, so that could be part of it. of attractiveness.

Mike Ashley’s big win with 17

Mike Ashley, the owner of Newcastle United Football Club, was playing at a private casino in Mayfair in 2008. He made a “complete bet”, which included all the splits, corners, fairways and six-line bets that include the 17 , and of course put a straight bet on 17 itself, just in case. He ended up winning £1.3m on that run.

Sean Connery defies the odds

Ashley might have thought 17 was a lucky number for him because Sean Connery had proved it so. The actor had just shot to stardom playing James Bond in Dr. No in 1962, the year before his historic victory at roulette. The story is related to how lucky he was to get that role.

It is said that Connery was gambling at the Casino de la Vallee in Saint-Vincent, Italy, where he placed five bets on the number 17. He lost the first two spins, but kept going. The third toss gave him luck and he won. Somehow, the gods smiled on him, as he put all his new winnings on 17 and won again. So instead of just walking away, Connery tempted fate once again and put all of his winnings back on 17 for one last round, which he also won.

The probability of this happening is 50.653:1. He left the table with more than $27,000 (which would be more than $228,000 today).

Why 17?

Most likely, the number 17 became popular due to its position near the center of the roulette layout, both on the French and American tables.

Also, 17 is a prime number, so it might seem like the most “random” number to humans.


The number 7 is also enormously common, most likely because it is considered lucky or at least quite prominent in the world’s major cultures. Do you remember the Seven Wonders of the World? We also organize our weeks around seven days.

There are also seven continents on the planet.

Also, it is an important number in most major religions:
– In Hinduism, there are seven heavens and seven nether worlds. The Vedas also speak of seven chakras.
– In Buddhism, the newborn Buddha got up and took seven steps, and there are seven factors of enlightenment.
– In the book of Genesis, God created the world in six days and rested on the seventh. Also, Judaism has seven holy days on the calendar.
– In the New Testament, the number seven represents the four corners of the Earth combined with the Holy Trinity.
– The New Testament also leans heavily on the number seven in the Book of Revelation (seven seals, seven angels, seven trumpets, etc.).
– The Koran mentions seven heavens, and Muslim pilgrims performing the Hajj circle the Kaaba in Mecca seven times.

Another reason it might be popular is because it’s also a prime number, and primes are often thought of as special. We can’t divide them cleanly, and so they seem more distinctive or unique.


This is another common number that appears frequently. After all, “good things come three by three”. It is also lucky in Chinese numerology because the word san sounds similar to the one meaning “birth” or “life”. It also represents the three stages of human life: birth, marriage and death.

The least favorite numbers of roulette players

Although many players have their favorite numbers, there are also numbers that veteran players shy away from – that pesky superstition is rearing its head again. What are the most unpopular numbers?


This seems easy enough: many Western cultures have considered 13 an unlucky number for centuries.


Possibly due to its location at the far end of the table, 0 is another unpopular roulette number. It can also have negative connotations for roulette players because it is the house number.


This number also seems to bring bad luck. Perhaps it is the belief that it is part of the number 666, an inauspicious number in the New Testament Book of Revelation.


This is another number that is on the table limit, so players shy away from it.

What is your lucky number?

No matter what your reasons are, you probably have a favorite number. Maybe it’s your birthday or your anniversary, or just a random number that appears in your life. Whichever number you prefer, it is important to you. Give it a try when you play your next online roulette game. If your number appears, you will have more reasons to keep it as your favorite.
