You have a 63.2% chance of winning, and if you win you will start over and place the original bet amount on two dozens again, only this time you will skip the dozen that was last landed on. The payout for this bet is 1:1, while the chances of winning it are 48.65% (18 in 37) and 47.37% (18 in 38) for European and American Roulette, respectively. Odd or Even – This is a bet on whether the ball will land on an even number or an odd one. Same even money bet result in a row probability. How unlikely is it to see the same colour 2 or more times in a row? What's the probability of the results of 5 spins of the roulette wheel being red? The following chart highlights the probabilities of the same colour appearing over a certain number of spins of the roulette wheel. The odds of rolling a 7 are 1/6. The odds of rolling an 11 are 1/18. The odds of rolling doubles are 1/6. Twice in a row are 1/36.

What are the roulette odds of the ball landing in the same colour ten times in a row? What about landing on the same number twice? Let´s take a look, and then we´ll explain how this relates to the Gambler´s Fallacy, or the Monte Carlo Fallacy- the belief that the odds of a black number coming in increase, the more times you see red.

Let´s look at a European Roulette wheel. Over a single spin, the odds of a red number coming up are 18/37, or 1 in 2.06. Over 2 spins, the odds of 2 reds coming in are 1 in 2.06×2.06, or 4.24.

The odds of seeing 10 reds in succession are 1 in (2.06) to the power of 10 = 1 in 1376.

Pretty low odds that you´ll ever see this, in other words. But that doesn´t mean it isn´t going to happen. In fact, the longest number of reds in a row was recorded in an American Casino in 1943 when 32 came up in a row. Now imagine that you were betting the Martingale that day! The odds of seeing that are 1 in 11 million, or thereabouts by the way.

Another huge streak (this time on black) was seen by the players at the Casino in Monte Carlo who saw 26 blacks in a row on the table on 18 August 1913. The odds of this happening? A mere 1 in 145,000.

And this gave name to the Monte Carlo Fallacy, otherwise known as the Gambler´s Fallacy, as the longer the streak went on, more and more people started piling their chips on to red. And they lost a lot of money.

So what happened?

Gambler´s Fallacy

The important thing to understand and to get your head around, is that these are odds over multiple spins. And here´s the thing. In roulette, you can´t bet on what is going to happen over 10 spins, you can only bet on the next spin. And thus the odds are always the same – 18/37, whether the red came in 10 times previously or not. The wheel has no memory from spin to spin. It is not a living thing.

Tip for Martingale Players

Martingale System Players are often susceptible to long runs as they double their bet after a loss. Start your first bet low if you employ this strategy to give yourself the most room for manouevre

One things for sure about the Gambler´s Falllacy- the casinos love it! Don´t get sucked in, keep your thinking hat on.

One thing’s for sure- there are plenty of people who have worked out that the odds are with the casino on roulette, and have opted to scam the casinos instead, like the roulette scam in Ohio. Just be warned- that’s illegal. They got busted.

FAQs Roulette Probabilities

• What are the odds of seeing 10 reds in a row on a roulette wheel?
  The odds of seeing 10 reds one after another are 1 in (2.06)¹⁰ = 1 in 1376. But remember, you cannot bet on 10 spins, only on a single spin. Here the odds are 1 in 2.06
• What is the definition of the Gambler’s Fallacy in roulette?
  The Gambler’s Fallacy is the incorrect belief that a certain event like flipping a coin or the ball landing on a black number is more or less likely, due to a previous sequence of events.
  This is incorrect for mutually exclusive events because each event is independent with a result that has no relation to past events. Think about it this way. Is the wheel thinking after each spin, “I spun a red last spin. Let´s throw in a black to even things up.” No.
