How Many Numbers On A Roulette Board
From there, it gets a more complex and—at times—a little arbitrary. For instance, adding any three numbers that appear horizontally together on the Roulette table can be related to the number six. The numbers 28, 29, and 30 appear horizontally toward the end of the table. The total for those three particular numbers added together is 87. Roulette is a semi-random game. And in case a particular number has not been a winner after a considerable number of wheel spins, say more than 70, it would seem that the number is set to win sooner than later. Many people tend to believe this, as they do not understand that every ball spin has absolutely nothing to do with events in the past.

The black numbers on a roulette wheel are 2, 4, 6, 8, 10, 11, 13, 15, 17, 20, 22, 24, 26, 28, 29, 31, 33 and 35. The red numbers are 1, 3, 5, 7, 9, 12, 14, 16, 18, 19, 21, 23, 25, 27, 30, 32, 34 and 36.
The sum of all the black numbers is 334 and the sum of the red numbers is 332. There are 10 even black numbers and 8 even red numbers. Naturally there are 8 odd black and 10 odd red.

There are 5 black prime numbers which are 11, 13, 17, 29, 31 and 5 red prime numbers are which are 1, 3, 5, 7, 23.
These number combinations are quite strange. They are not balanced and they do not give the impression of being random though of course they could be. In fact if numbers were sequential and ran from 1 to 36 with alternating black and red colours, or if all the red numbers were even and all the black were odd, it would not be possible to state categorically that these were not random.
The point of all this is that any sequence of numbers from 0 to 36 that are generated in a random manner is just as likely as any other sequence. In the National Lottery you are just as likely to win with the numbers 1, 2, 3, 4, 5, 6 as you are with any other sequence. This is a fact that everybody knows but very few people actually believe.
It does matter if a string of numbers generated by an online casino hosting a game of roulette is or is not truly random. If the numbers are other than random the casino might be accused of cheating.
Alternatively a gambler might detect a pattern in a string of numbers that they could exploit in order to increase their chances of winning.
How Many Numbers On A Roulette Board
So how do you test is the numbers generated in an online roulette game are random? This is very difficult to do.
One way is to look for any patterns within the numbers. An excellent way of doing this is to produce a bitmap of the numbers and use human beings to physically look at the bitmap to see it there are emergent patterns. This is surprisingly effective. There are many format statistical methods that can also examine data for non-random patterns and casino random number generators are frequently audited and must pass these tests.

It’s no secret that people are a superstitious bunch. Detectives act on their “hunches”, students taking exams cross their fingers and knock on wood, and hotel owners skip from 12 straight to 14 in their floor plan. And in roulette, players favour some numbers over others. Is there any rhyme or reason to this, or is it simply what it sounds like: an old wives tale? Can humans really tap into something deeper when it comes to luck and probability, or are we really all stuck in a gradually overheating RNG machine?
A Brief History
The link between betting and probability has a long and intermingled history. In fact, gambling is the mother of probability. Blaise Pascal, who accidentally invented the roulette wheel in his attempt to construct a perpetual motion machine, struggled with the idea of probability from a mathematical standpoint. Through the contemplation of a notoriously difficult hypothetical gambling problem, he and Pierre de Fermat formulated the theory of probability. Before this time, there was no other “scientific” way for people to rationally predict outcomes to situations. They had to guess and trust their gut instinct. Since roulette and the theory of probability have grown together side by side, why is it that many people still adamantly hold onto their superstitious ways? Perhaps, sometimes there really is something that guides people to choose the way they do.
The Legend of 17
The number 17 is the number in the centre of the roulette board and is also famous for delivering some staggering wins.
- “Newcastle boss wins £1.3 million on lucky number 17”
- Sean Connery wins on 17 3 times in a row
If you ask croupiers what the most common number people bet on, the answer will always be 17. Not only does it lie in the centre of the board, making it the most obvious place to bet, MIT have described the number 17 as the “most random number”, meaning that when people choose a random number they go straight for 17. In several studies when correspondents were asked to choose a random number from 1 to 20, 17 was the most frequently chosen, making it the least random number by human standards. 7 followed closely behind. Computerised RNG made no such biases.
So, perhaps the phenomenal wins commonly associated with the number are simply because more people bet on 17. Ashley, a long time roulette player, most likely bet on the number 17 a lot of times before he hit his big break.
Sean Connery’s Staggering Win
But, this doesn’t explain Sean Connery’s unbelievable achievement on the roulette wheel. Reportedly, while playing in Casino de la Vallee in Saint-Vincent, Italy, he placed 5 bets on the number 17. The first two he lost, but he persisted. The third time lucky, his number came up winning him 31:1 odds. Not content to settle with that, he placed all his winnings back on the number 17. Literally against all odds, the movie star wins again. Instead of walking away, Connery tempts fate and puts all his money on the 17 for a fifth and final time. The number comes up. Apparently the probability of hitting three single number bets in a row is 0.0000197% or 50,000:1. While it is weird that it would be the same number three times in a row, mathematically it’s like as likely as Connery guessing any other number correctly. Of course, that doesn’t make it any less bizarre.
What on earth is going on here? Perhaps the number 17 truly is a mythical number for roulette.
Perhaps the reason is simply that Connery spotted a bias with the roulette wheel, and went with it. However, since the roulette wheel missed the mark the first two times, it still seems extremely risky. Maybe Connery was simply in the mood for a thrill! Or, perhaps he slipped the croupier a little something under the table… Sadly, we will never really know the answer to the mystery of the number 17. We can see why people love betting on it though!
Other Common Lucky Numbers
The number 7 is perhaps the most common number that people like to bet on, after 17, because it is generally considered to be lucky. People also love the number 3, as everyone knows all good things come in threes. However, these numbers are all lucky in the Western culture. Eastern casinos would tell an entirely different story of what the most common numbers bet on are. For instance, the number two has extremely positive associations in Asian casinos: double your luck and double your chances!

Least Favourite Numbers To Bet On
As we already mentioned, people tend to avoid the number 13. Its unluckiness is well established throughout most of Western culture. However, in Italy the number 13 is lucky and the number 17 unlucky. So, if you are betting with an Italian you can expect them to do the reverse of what you might expect. Players universally tend to dislike betting on the zeros, perhaps because of the placement on the board, and perhaps because of their unlucky associations with the house edge.
Conclusion
17 is a very common number to bet on, which is most likely why you hear so many great success stories surrounding it. 7 is also very common and has enjoyed fame because of a number of big wins associated with it. The more fame these number have, the more likely people are to bet in them – thus increasing their fame and luck further.
Whatever number you bet on mathematically has the same chance of coming up. So if you do have a favourite number spread that means a lot to you, like a birthday or anniversary date, there’s no reason why you shouldn’t use it. They are just as likely, or rather unlikely, to come up as any other. Then, when your numbers do come up you’ll have all the more reason to favour them! Keep this in mind when playing online for real money.
