The mechanism of the roulette wheel is quite interesting! There are a lot of interesting facts can be found about this part of roulette table. The spaces of roulette table are colored the same with the slots colors of roulette wheel for you to see clearly what number and what color you make a bet on. 48.60% are the odds on a roulette table for a wide range of outside bets. For example, the bets including Even/Odd, Red/Black or Low/High offer the highest odds on roulette with European (48.60%) and American (47.40%) layout. These roulette betting odds mean that your chance to hit a win is almost 50:50. This article focus on a roulette red / black strategy that is better suited to the average player. There are proven winning roulette systems revealed on this website. But before betting with this strategy, learn why most players lose and learn what happens when you use a roulette betting progression. Players, who are new to roulette, should note that, although the game offers a variety of betting opportunities, there are certain limitations to be taken into account as well. Once seated at the roulette table, a player will probably notice the plaque, standing on top.
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?
Most people believe that the color red appears most frequently on a roulette wheel. In other words, the ball lands in a red-colored pocket more than it does on the black or green-colored pockets. However, there is no definite way to confirm if this belief is true. You must remember that roulette is a casino game that relies mostly on luck.
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).
| The Same Number Comes Up in a Row | True Odds to One in FRENCH Roulette | True Odds to One in AMERICAN Roulette |
|---|---|---|
| 37 | 38 | |
2˟ | 1,369 | 1,444 |
| 50,653 | 54,872 | |
4˟ | 1,874,161 | 2,085,136 |
| 69,343,957 | 79,235,168 | |
6˟ | 2,565,726,409 | 3,010,936,384 |
| 94,931,877,133 | 114,415,582,592 | |
8˟ | 3,512,479,453,921 | 4,347,792,138,496 |
| 129,961,739,795,077 | 165,216,101,262,848 | |
10˟ | 4,808,584,372,417,850 | 6,278,211,847,988,230 |
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...

What Is A Roulette Coloring Book
The French roulette wheel is a contrasting theme of reds and blacks, broken by a single green slot. There are 37 numbered compartments from0to36, though no ordered numerical sequence is adopted, there is a correlation between the color and whether a number is odd or even.
As there are '8 RED EVEN' and '10 RED ODD' and in comparison '8 BLACK ODD' and '10 BLACK EVEN' roulette wheel/table numbers.
French and European roulette wheels have only onegreen coloured slot, the zero number. Each number changes color repeatedly between the roulette signature colors ofredand black.
American roulette wheel
The American roulette wheel has an extragreen compartment for a double zero '00'number. Shown in the picture below.
Double Zero '00' the extra compartment added to the American roulette wheel, diagonally opposes the single zero '0'. But the extra double zero isn't the only modification made. The American roulette wheels number sequence in comparison to the European/French wheel, is completely different too.
Though each numbers color hasn't changed i.e. black 22 is still black 22 in both wheel types. The frenetic randomness of the French wheel sequence is less so in the American wheel with regards to diagonally opposing numbers bearing some relation to each other like1and2 oppose each other, the pattern continues up to35opposing36possibly done this way as the zero and double zero face one another to bring about a pleasing symmetry when in designing the American roulette wheel.

The Roulette Wheel
with the Best Chance
The Roulette Wheel with the single green slot marked as a [0], is of the European and French Roulette wheel games. Compare this to the American Roulette Wheel which has one more green slot on the wheel marked as a [00] and you can see that your chances of winning are reduced by this additional green slot.
The Casino has nearly a 3 percent advantage over the player with the Roulette Wheel pictured on the left and just over a 5 percent advantage with the American Roulette Wheel. Playing online you have the choice of both wheels.
