Types Of Roulette Ball
Posted : admin On 4/2/2022Roulette is one of the most popular casino games, and it is always the image that you first think of when you think of a casino. And when it comes to roulette, there are two main variants that are seen everywhere. These are American Roulette and European Roulette. Americancasinos.com is here to help you understand the differences between the two versions.
The most significant and most obvious difference that you will see is the wheel. The numbers are in a totally different layout on the two wheels, and although they both feature the numbers one to thirty-six. The European roulette wheel has a single green zero that sits at the head of the wheel. The American roulette wheel has the same single green zero at the head, but it also has a green double zero, that sits directly opposite it at the foot of the wheel. This means that an American wheel has thirty-eight pockets on it, to a European wheel’s thirty-seven.

- A roulette table displays the range of numbers that you can bet on as well as the broader categories for the bets. This includes odds, evens, black, red, the lows (1-18) and the highs (19-36). This allows you to bet on a range of betting options instead of just making individual wagers on numbers or colours.
- Roulette Royale has a jackpot that continues to grow. Progressive jackpots mean you could be playing for hundreds of thousands of dollars. If the ball lands on the same number five times straight, you get the jackpot. Multi-Player Roulette is a type of European Roulette that.
- La partage – the player gets 50% of the outside bet if the ball lands on zero; European Roulette. The most popular type of roulette in Ireland, it has the same type of wheel as French roulette but a different table. The zero is still facing the wheel, followed by a number chart, however, all outside bets must be placed in the chart below the number.
- In the dedicated classic roulette version articles, you’ll learn that the seemingly superficial differences between the three main game types are of great importance. They, in fact, impact the house edge and, therefore, picking the right roulette game might make a difference for the final result of your gaming session.
This makes a difference when it comes to the odds of winning and the house edge. The house edge is the amount that the house will win over any extended playing time. On a European wheel, the house edge is just 2.7%. This is not a bad advantage for the house, and it means that they do make money. The way this generally comes about is because if the ball lands on the green zero, then all of the bets the players have made loose. When this is a 1/37 chance of it happening, it means that the house will win on average once every thirty-seven spins. All your Black/Red, Odd/Even and High/Low bets are all suddenly losers. If you take into account that picking a winning number on a roulette wheel, pays you back 35/1 (i.e. you get your stake, plus 35 times your stake, for a total of 36 times your money) but your chances of winning are 1/37 then it is clear to see that the house can make some money.
Contrast this with an American wheel. Here the house edge is even more. It now runs out at 5.26%. And this is all down to that extra double zero. The payout for a correct number bet is exactly the same as on a European wheel, i.e. 35/1, but this time the chance of guessing correctly is only 1 in 38 because of the extra double zero. Both the zero and the double zero are losing bets to the players, so in fact the house will win one in every nineteen spins, because of the two zeros, giving them a much better house edge. Therefore as a player, you want to know which wheel you are playing and how the odds work so that you can maximise your winnings.
The extra double zero also has an effect on any of the other bets you can make, not just the straight number guesses. Say you went with Red or Black, then on a European wheel the chance of you winning is just 48.65%, not the 50/50 that you would expect, and this is because of the green zero being a losing bet either way. Compare this with on an American wheel and the chance of you getting it correct drops even further to 47.37%, due to the addition of the double zero. This is much less than you would have thought.
However there are some good things to be said for American Tables, there are a few bets that can only be made on an American table and not on a European one, and this is due to the way the table is laid out. On an American Table, you can place a bet on the top line of five numbers, which you can’t on a European table. This sort of bet will pay you odds of 6/1 as well if any of your five numbers come up, so it is a pretty good return. Though you should know that this type of bet does affect the house edge, and increases it to 7.89%, so although you can win more, you will win less often. So again, bear this in mind when placing your bets.
It is good to understand what the house edge actually means in practice to the amount of money that you can make. If you look at a European wheel the house edge of 2.7% means that if you place a total of £100 in bets across a total of 37 spins of the wheel, then you would expect to lose about £2.70. Which isn’t a huge amount, but for the house, those amounts add up over time and players to mean big profits for them. You should also bear in mind, that if say, you and another player placed £50 of bets each across 37 spins, then it could well be him that loses the £2.70, or more, while you win more. So there are still ways of you making money.
A different way to understand the difference between the house edges on the two wheels is as follows if you were to bet on a European wheel, £1, then after thirty-seven spins, you would have lost on average one unit of bets. If you were to do the same on an American wheel, £1, after thirty-seven spins, you would have lost two units, so twice the amount of a European wheel.
Intro
It has always been a question among aficionados of this old gambling game- how to turn the odds in your favor? Are there any particular strategies and tricks hat can increase your winning chances?
Trying to be as creative as possible in thinking of ways to bring luck by their side, people came to the conclusion that wheel malfunctions and biases can also be used for this purpose.
Could they, indeed?
Here’s the chance to learn MORE about this!
What is a biased wheel?
When specific numbers win more frequently than they should, that because there are biases in a wheel. The most common causes for this are defects in wheels.
Just to make one thing clear, these malfunctions are not a secret, most players know about them. They used to rely on this “technique” by analyzing lots of spins and wheel structure in order to figure out the pattern. However, that made sense like 100 years ago, but with modern technologies involved in gambling, things have significantly changed.
Nowadays, you have automated software which analyzes the winning numbers in order to identify the existence of a potential pattern in winning numbers. The better the software the more accurate the analysis is the logic.
Three types of biases in roulette wheels
- When a ball favors a single pocket it is a pocket bias.
- If a specific sector on the wheel is favored, it’s a section bias.
- The last type is a dynamic bias and it usually works for just a few hundred spins. What characterizes this type of bias is the prediction of its evolution, which serves for adjusting bets. This type favors the players, so to say, as modern software fails to catch it.
What causes wheel malfunction and how to spot it?
As the wheel itself is a complex machine, so to say, made of many parts there are many causes why biases occur. Sometimes there’s only one from the list, but it’s not uncommon to have two or more of these.
Here’s THE list!
Loose pocket separators
They are also known as frets, and as a result of loosening, they become better in absorbing the impact that the other pockets. This leads to ball resting in a specific fret more frequent than in the others.
Variations in pocket size
As there are no two frets of the same size, consequently ball doesn’t favor all of them equally. The logic says the larger the fret the more often the ball will rest in it. Higher frets have mechanical flaws more often than the lower ones.

Damaged fret surface
Even though this may seem insignificant, but even the tiniest scratches, barely visible to the naked eye, change the friction and the level of impact absorption. Like the previously described, this also causes the ball to rest in some place more often than in the others. This malfunction is also known as “deadening”.
Wheel wobble
When one side of the rotor is even a millimeter lower than the opposite, that “spoiled” gravity leads to lower side being more favorable compared to the opposing. This malfunction is among the easiest one to spot. You just need to stand in the right place to see it.

Unbalanced wheel deceleration

You know a wheel is unbiased when it moves smoothly and constantly, without speed variations. However, when you notice slight deceleration when the zero is at a particular point around the wheelbase. There are many reasons why this happens, but the distorted wheel shaft is among the most common ones. Multiple factors are part of this one, such as tilted wheel which leads to a common drop point further resulting in a sector bias. The trick how to spot this malfunction is to observe green zero for a few spins.
Tilted wheels
This one itself is not a malfunction, but when in combination with some others, it results in a sector bias. To spot this one, you have to mark a point where the ball strikes a diamond, for example. This, of course, goes for the wheelbase, not the rotor. The result of this malfunction is ball being favorable to some pockets comparing to the others.
Common ball drop points
As you have seen, this one is strongly related to the previously described bias, as well as unbalanced wheel deceleration. This malfunction also belongs to a sector bias.
Deformed ball track
When the deformation in a track occurs, that also leads to common drop points. The method of detecting this one is rather unusual. What you have to do is listen to the rattle, and when you locate the point where it occurs, you are a step closer to spotting common drop points.
Deformed and poor quality ball
Balls are never perfectly round, which also leads to biases. If you hear it rattling at the same part of the wheel, then be sure that there’s a deformation in a ball.


As you can see, there are truly many parts where malfunctions can occur. All it takes is patient observation and after a while, you will spot all the biases. It’s worth mentioning that older style wheels are more likely to be biased.
How to spot a biased wheel?
Taking all the above-mentioned factors into consideration one may get the impression that spotting a biased wheel is a piece of cake.
Well, it’s NOT!
Double Ball Roulette
One has to be an expert in understanding all the mechanics behind the roulette wheel so to spot where do biases occur. Biased wheels are indeed rare. Even though manufacturers do their best to create a wheel without any defects, still malfunctions happen.
As we mentioned, casinos use software to detect them, but you can always use good old manual technique and investigate. This is a complex action, which requires keeping a record of all the things you have noticed, such as damages, imperfections as well as conditions when and when certain things happen. To be completely sure that it’s not just a coincidence, repeat your test.
If the results were matching- congrats, you’ve found it!
But do be aware that casinos also pay close attention to this, so don’t let it surprise you if one day you notice the bias and the next day- PUFF, it’s gone!
