Lots of people have trouble with this. If you bet before any spins on six in a row, the chance of winning is 1/2^6=1/64. But having seen the five reds, as you say, the chances are 1/2 each on red and black for the next spin. It is also true for any specific series of six spins, at the start the chance of that series is 1/64. Therefore, the odds against winning with a Straight Up bet on 32 Red are equal to 36/1. These reversed odds are normally used by gambling establishments to list the payouts of the winning bets. The smaller the likelihood of winning with a given roulette bet, the greater the return offered by the house. . This bet can only be placed on a double-zero roulette table (i.e. On an American table and not a European or French one). It covers the numbers 0, 00, 1, 2 and 3. Individual roulette bets in more detail. Here is a quick overview on the different types of roulette bets and odds of each bet that can be made in roulette. Roulette is a very simple game in its nature. It’s played using a roulette wheel that has 37 or 38 numbered and colored slots on it: European (French) roulette: numbers from 1 to 36 (red or black) and 0 (green) American (double zero) roulette: numbers from 1 to 36 (red or black), 0 and 00 (green).

How many times in a row has a little ball landed in the same pocket of a Roulette wheel, i.e. how many times has a single number occurred in a row? And how about the same color? What is the probability of these events and a potential impact on a play?

Record Occurrence of a Single Number in Roulette

The probability that any single number occurs is 1/37 in French Roulette and 1/38 in American Roulette (there are 36 numbers + zero + double zero in American Roulette). There is no doubt that it is a great coincidence when the same number comes up again and again.

The longest reliable series was registered at the hotel El San Chuan in Puerto Rico on 9 June 1959. During the course of the American Roulette, number ten occurred even six times in a row! The probability of such (successive) events is determined by a multiplication of individual events. Therefore the probability that the same number comes up six times in a row is:

(1/38) ˟ (1/38) ˟ (1/38) ˟ (1/38) ˟ (1/38) ˟ (1/38), that is:

(1/38)6 = 0.000000000332122593261671.

That is a very small number indeed, roughly three billionths only. If we convert this probability into true odds that would have to be offered to us by a casino, we get the value 3,010,936,384 to one. The true (fair) odds are calculated as a reciprocal of the probability, that is 1 ÷ probability. If such a bet on a series of outcomes was possible in Roulette, we would win $3 billion for a $1 bet(!)

It is important to add that the above-mentioned calculation of probability deals with a multiple (successive) events, i.e. we can ask this question: What is the probability that the same number in Roulette comes up 6 times in a row?

Since it would be a different case if e.g. number 10 occurred and after that before the new spin we asked what was the probability that number ten came up again? In this case the answer would be 1/38 (in terms of American Roulette), because any number could occur with the same probability 1/38 in every new spin. That is what we call a simple event in contrast with a multiple event(s) whereas the probabilities of individual events are multiplied (→ Articles on Probability).

The true odds for a 1 to 10fold repetition of the same number are shown in the table below. It is the same mechanism as if a sporting bet company or a casino offered the odds for a victory of some home team in some football match (→ The Odds Determination and Calculation).

Roulette Odds Of Consecutive Red And Blue

The odds are reciprocal values of the probabilities – the higher they are, the lower the probabilities are. The case of the above-mentioned record series is marked green. Consider also the difference that is made by one extra number in American Roulette (the double zero).

Record Repetition of the Same Color in Roulette

There are no exceptions that the same color appeared more than 20 times in a row in practice. The record was registered in 1943, when red color came up 32 times in a row! The probability of such event in French Roulette is (18/37)32 = 0.000000000096886885 with the corresponding odds 10,321,314,387:1.

The probability of the 32fold repetition of the same color in American Roulette is much more lower: (18/38)32 = 0.00000000004127100756 and the odds are 24,230,084,485:1. Thus this is even less likely than occurrence of a single number six times in a row. Again it is clearly demonstrated what kind of importance (a negative one for players) has just one extra number in American Roulette.

Now imagine that you used the Martingale betting strategy (→ see the first test of the Martingale system), whereas the next bet is doubled if your bet loses...

Record Breakers….
What is the record for the number of reds that have been recorded in a row on a roulette table? Actually, we are interested in any of the even money bets, so red/black, even/odd, high/low and so on.

This question is particularly interesting for players of the Martingale Roulette system and goes right to the heart of the Gambler’s Fallacy- that mistaken belief that if you see 5 reds in a row, the next result is more likely to be a black. This is a myth, of course- each and every roulette spin is what’s known in statistics as a mutually exclusive event. There is always an equal chance of red and black coming up on an individual spin- the result is in no way affected by previous results.

Marty System
Martingale players are also interested in this question, because this system involves you doubling your bet after a loss. It’s generally played on the even money bets, and the idea is that at some point you will win and claw back all of your previous losses.

Players often look out for long strings of the same result, such as R,R,R,R,R. They’ll then bet on black in the hope that the results will flip back to black to restore the long term equilibrium, something that the D’Alembert system also tries to do.

If you are going to play the Martingale…….

Start your bets low and choose a table with a high limit. That way you will at least give yourself the biggest room for manoeuvre if you suffer a string of losses.

But if you experience 10 reds in a row, that will blow most Martingale players out of the water, as they’ll either throw in the towel or hit the table limits, after which they won’t be able to double their bets and cover their losses. It’s difficult to figure out the best roulette strategy under these circumstances.

Repeat after me……
These long strings of the same even money results are rare, but they do happen, so you need to factor this risk in if you are playing the Martingale. There are two main risks to this system- one is that you experience a very long string of the same result. The other is that the ball drops in to the zero pocket- that pesky little area that gives the casino its house edge.

You can devise strategies to counter this of course. You could bet with the flow of results rather than against it after you see, say, 5 in a row (but you might have picked the exact time that this wheel of all roulette wheels decides to behave more “normally”). You could also choose a game that offers La Partage which will at least soften the blow of the ball landing in the zero pocket. La Partage is a rule followed by some casinos where they refund half your even money bet when the zero drops in. Many French roulette games offer this.

The Record For the Number Of Reds in a Row

So, this will scare you Martingale players! What is the record for the number of reds in a row? Check out this picture from the Rio All Suite Hotel and Casino in Las Vegas. This had all the punters thinking that the wheel was rigged- 7 reds came up in a row (you will see 7 in a row at some point for sure) but these were all the number 19!

Wow
The record for the number of reds in a row was set in the US in 1943 when the colour came up 32 times in a row. The probability of this happening on a European Roulette table is (18/37) to the power of 32 which comes to 1 in 10,321,314,387.

it has also been reported that red came up 39 times in a row in the Casino Monte Carlo, Monaco.

You can see how it doesn’t come up much, but it can happen! Luckily, I should think if anyone was playing the Martingale on that table, they hit the table limits WELL before the 32nd spin.

That’s a Slim Chance, But it Happened
This was probably seen on an American roulette table which makes it even more incredible, because in this case the probability of it happening was (18/38) to the power of 32 which comes to 1 in 24,230,084,485, almost 2.5 times less likely because the American wheel has 2 zeros.

Here’s the thing though- on the 32nd spin, the probability of the next spin coming up red or black was the same- 47.3%. Talking about individual spins and 32 spins is a whole different ball game, and in roulette you can only bet on one spin of the wheel.

If you do a search on Yahoo, you’ll see that many people claim to have seen over 10 in a row on the roulette table. One guy claims to have seen over 15 at least 5 times (I guess we don’t know how much roulette he plays to gauge the percentage of his visits that this represents). Even so, it does happen. 5 in a row, 6 in a row, 7 in a row, 8 in a row and so on is going to happen more frequently. 14 in a row seems to be the big one that people are talking about in their personal experiences.

What About Black?

The weird thing I find about these stories, is that everyone always talks about red. I mean, what about the record number of blacks in a row? Or the record number of evens in a row? Or odds? Or high numbers? Or low numbers?

There is a famous session where a roulette ball on a specific wheel landed on black 26 times in a row in a Monte Carlo Casino in the summer of 1913- August 18 to be precise. This even spawned the name “Monte Carlo Fallacy”. Players at the table lost millions of francs betting against the black.

But generally, all the noise is on red, right?

Why People See Red and Not Black
I think here we are into human psychology. Red is an emotive colour, and it’s the one that people talk about the most. Black also gets noticed to a lesser extent, but the others? There has probably been a case of 20 high numbers or odd numbers occurring in a row in a casino, but no-one probably noticed.

So, this brings up an interesting point for us, one that we touch on in our Even Money Switcher system.

If you are tracking the even money results, you don’t just need to bet on red/black. You can look for patterns on the other bets as well. 23 reds in a row has been documented, but I have never heard of 23 high odd red numbers in a row.
