What Are The Most Common Numbers In Roulette?


When playing the game of roulette, it’s generally understood that it’s a game of chance. There are a certain amount of numbers and colors, and your chance of winning corresponds to what you choose.

What’s not generally known is the exact percentages across the board. Players will often have some rough ranges in mind but the specifics matter. We’re going to take a look at the online roulette odds probabilities and tell you exactly which numbers are most common so that you don’t have to guess the next time you play.

What Numbers Hit the Most in Roulette?

  • The Most Common Roulette Numbers: Odd, Even, Red, Black, 1-18, 19-36 Hits 46.37% Of The Time

If you’re merely looking at which numbers pop up the most frequently in roulette, it’s the choices of odd or even, red or black, or 1-18 or 19-36. The math is quite simple: these each dominate the roulette wheel save for a couple of spots for 0 and 00.

What this means is that if you’re looking for the easiest path to victory, it’s betting on one of these six options. However, keep in mind that the payout for these online casino games is one-to-one – even though they show up less than 50% of the time.


  • Play Dozens, Columns To Hit 31.58% Of The Time

If you’re playing at a real money online casino, it’s essential to understand probability. The next most likely probability on the roulette wheel will hit 31.58% of the time. In Lehman’s terms, that means they’ll pop up just under one-third of the time. To get those types of percentages in your corner, you’ll have to play either the Columns or the Dozens.

In case you’re not quite familiar, there are 36 numbers on the roulette wheel, so if you play the Dozens, you’re taking either one through 12, 13 through 24, or 25 through 36. As for the Columns, you’ll see the table is broken up into columns you can choose which set of 12 numbers you want to go with. Similar to Dozens, you’re getting 12 numbers.

When you do bet 12 numbers, you’ll get a payout of 2/1 if your number comes up.

What are Hot and Cold Numbers?

Hot and cold numbers are numbers that hit more or less often during a roulette game. If 7 on red is hitting continuously, this is seen as a ‘hot’ number, and a number that isn’t hitting is a ‘cold’ number.

Some people believe they’re more likely to win by betting on hot numbers, but it’s important to remember that roulette is a game of chance, and this method is based on luck rather than odds.

Sometimes, betting on one number — even a ‘cold’ number — can result in a lucky win. Sean Connery, who famously played the baccarat-loving Bond, won $27,000 betting on 17, 3 spins in a row — allegedly.

Betting The Rest Has Small Probabilities Of Hitting 

A lot of people are attracted to betting a single number on a roulette table to test their luck. Of course, the payout is quite attractive because if Lady Luck is on your side, you get to cash out with odds of 35/1. However, you only have a 5.26% chance of connecting on this type of win, so it’s not very likely to come through for you. You can also do something like bet two adjoining numbers to double your chances of winning but your payout gets cut to 17/1 in this case.

A lot of these bets are tantalizing because of the jackpot-like payout but they hit the least, so keep that in mind.

Why is the Number 7 Important in Roulette?

The legend behind ‘7’ is largely based in superstition — 7 is considered a lucky number in many parts of the world, and many people feel like this goes for roulette odds, too. In roulette, 7 red is one of the most popular picks (and interestingly enough, 7 is also one of the most-often chosen lottery numbers).

Why We Mention Sean Connery When we Talk Roulette Numbers

In 1963, just one year after his star turn in Dr. No, Sean Connery became a roulette legend when he placed 5 bets on the number 17 at the Casino de la Vallee in Saint Vincent, Italy — and won 3 of them.

The odds of winning this bet? 50,000:1, or 0.020%.

And 45 years later, ’17 black’ continued to prove lucky for Newcastle United owner Mike Ashley.

Ashley won a whopping £1.3million, (about USD $1,504,418.50), on a £480,000 (~USD $555,477) wager. A 92% increase on your bet? Not too shabby for a billionaire.

The Reality Is That Your Bets Probably Matter

Yes, yoiur bet matters in roulette.

Surprised by the title of this section? While there are some helpful tips like the Martingale strategy, believe it or not, this is the reality because all bets are just about equal in roulette.

Of course, not all bets are EXACTLY the same; some pay more and have a smaller chance of coming through and some pay less but are more likely to appear. What we’re talking about here is the expected value – also known as EV – and that will show you that no matter what you bet, you’ll have a negative EV of -5.26%. In other words, if you bet placed $100 bets over a period of time playing roulette, the long-term expected value would be that you leave with $94.74.

What’s interesting is that the expected value is the same whether you’re betting a Dozen or Red or a specific number. Even though all of the payouts are different and the probabilities vary, the Expected Value is all the same.

So, what is roulette all about then? Well, if you’re trying to be pragmatic, the idea is to think about two things: volatility and luck. Starting with the first, playing the less volatile bets – like the ones that have higher probabilities of hitting – will lead to less of a bumpy ride. You won’t win as much but you won’t lose as much either, and your money will last longer at USA online casinos. That’s all you’re really thinking about when it comes to volatility.

As for luck, it’s merely how you’re feeling. If you think it’s on your side, get out there and have some fun. The long-term expected value says one thing but your luck might say another. You never know as it just might be your night!
