Many beginners tend to make a common mistake: they put real money in roulette, hoping for the effectiveness of the chosen strategy, betting system or a third-party programme. Meanwhile, experienced players recommend figuring out operation concepts of online roulette before trying out different roulette bets. Knowing operation principle of online roulette, it is easy to determine which betting systems or strategies will be really effective and which ones are time-wasters. What you have to understand, essentially, is how the roulette wheel works at online casinos, so that you could play to win and make correct bets.
How does Roulette Work?
How many numbers are there on a roulette wheel? What is the highest number on a roulette wheel? How to play roulette at casino? What are the best roulette numbers? All these questions bother those who have just started out on their gambling journey. Well, let's start with the basics.
Everything that you see on the screen while playing roulette, in fact, is nothing more than a video created by computer designers. Carefully drawn graphics leave a feeling (especially with regard to virtual 3D roulette) that the roulette wheel really rotates, and the ball moves along some trajectory and falls into the cell. In fact, this is nothing more than a masterfully created illusion: the sector in which the roulette ball will stop is defined in advance and is determined at the very moment you pressing the Spin button activating the rotation of the wheel.
Any kind of online casino roulette is based on a random number generator, i.e. a complex programmed algorithm that determines the best roulette bets and the outcome of each spin, that is, the number that will fall out in the end. Therefore, even if you see that the roulette wheel is spinning and the ball is moving, the outcome in fact is predetermined much earlier.
It is important to note that the operation principle of online roulette has nothing to do with the type of the bet you have made. Regardless the field you bet on or the amount of sum, RNG will give its result. For example, for the simple reason that you specifically bet on red, the ball will not stop on black in order for the online casino to withdraw your money; the outcome of each round is completely random and does not depend on the rates of the previous rounds.
In addition, unlike traditional casinos, physical factors do not affect online casino roulette, for example, a wheel roll that is not visible to an eye; nevertheless, this factor has been for a long time used to win at roulette in ordinary gambling establishments. The animation you see on the screen is intended only for entertainment and does not affect the outcome of the game.

Operation Concept of Online Roulette and Advantage of Online Casinos
Another important factor that you should pay attention to before start playing roulette is the advantage of a casino. In general, this concept is hidden in simple mathematics: a certain percentage of the total bets made by a player is taken away by online casinos as a profit, while the rest is paid back as a win. For example, if a casino advantage is 5%, then you are guaranteed to lose these 5% in form of losses, no matter how effective your strategy would be. The remaining 95% of your game budget will be returned in form of periodically paid winnings.
As everyone knows, the roulette wheel is divided into exactly 37 sectors: 36 of them are numbered from 1 to 36, and one more is the green zero sector. It is this sector that symbolizes the casino advantage in online roulette, but only symbolizes, because you can bet even on zero and win in the future. The meaning of the online roulette operation principle is that each round has 37 possible outcomes, but a casino pays the player as if there were only 36. In other words, the payout in case of winning is 1/37 or about 2.7%, i.e. less than it should have been.
For example, if you bet on red, then in theory, the chances of winning are 50 to 50. In practice, they are lower due to the presence of the 37th green sector. Since there are 18 red sectors, 18 black sectors and 1 green sector on the roulette wheel, the chances of getting red are 18/37 = 48.7%, but not 50%. Therefore, the payout should be equal to (37-18)/18 = 19/18 = 102.7%. However, the casino pays only 100% for winning at this rate.
The above calculations apply to European roulette; in American roulette, the casino advantage indicator is even higher and amounts to 5.27%. That is why this kind of game is considered the most disadvantageous. Surprisingly, even experienced players who are well aware of the online roulette operation principle often make the same mistake when choosing a completely unfavourable kind of game (for example, the same American roulette). It is absolutely impossible to do this in order to guarantee yourself at least some chance of winning.
Although the basic operation principle of online roulette can't be changed with the help of special software for online casinos or by hacking or disrupting the operation of RNG, it is still possible to win this game. However, there is one condition: a player can get profit only in a short-term gaming session (precisely because of a casino advantage, which effect is especially noticeable in the long-term). That is why experienced players for whom playing online casino games has already turned into a kind of work allowing to get a stable income often adhere to progressive betting systems. The main principle of such systems is a quick increase in bets (that is, the ability to quickly get a big win), and the game session that automatically ends as soon as the player receives some profit.
How to Guess the Number: Most Common Roulette Numbers
Payments in roulette at any online casino, regardless of the rules and type of the game itself, are always not too large. For instance, for bets on equal chances providing the greatest probability of winning, the payout is more than a modest 1 to 1; there are no such small payouts in any other game. The maximum payout in the amount of 35 initial bets can be obtained by betting on a single number. That is why many novice roulette players in online casinos are concerned with the same question of how to guess the number in roulette. In this article, we will try to figure out whether it is possible to guess a single number in order to receive a payment of 35 to 1, and what exactly is required for this.
How to Calculate the Roulette Algorithm Manually
The function principle of a random number generator determining which number will be the next is a complex mathematical formula. Accordingly, it is quite natural that no experienced player even tries to calculate the online roulette algorithm completely in manual way without using any foreign programmes. However, if you do not need to thoroughly understand RNG function principles and complex mathematical formulas, it is always possible to limit yourself to the simplest method of algorithm computing.
In this case, you need to proceed as follows: choose an online roulette that allows making idle spins, that is, scroll the roulette wheel without bets. At the same time, it is necessary to play only for real money, because there is a chance in free demo version that roulette will work according to a completely different, more beneficial algorithm for the player so that the user believes in high chances of winning. Once you have chosen the right game, start creating your database. Of course, in reality, it looks easier than it sounds: all you need is to record all the sectors that fell out scrolling the roulette idly. As a result, you will get a certain array of dropped numbers and will be able to notice some patterns analysing it. By the way, it is not necessary to complete this work. For example, if during the recordings you notice that black sectors have fallen several times in a row, you can interrupt a series of idle rounds and put on red. Using this method, you will win with great probability.
How to Guess the Number in Roulette Using Software
To be guided by intuition or premonition, bet on your own lucky number, and hope for a favourable outcome is not the best strategy for guessing the number in roulette. Moreover, the chance that you will guess the number that will win in the next round is only 2.63% in this way.
Certainly, there is another tactic of the game as follows: bet on the same number for several spins in a row, hoping that eventually this sector will fall on the roulette wheel and paying 35 to 1 will pay off all your expenses. However, firstly, there is always the possibility that the number you have chosen will not fall out during all 35 or even more spins. Secondly, with each next round that you lose, the total amount of your profit decreases; even if in the end you get paid 35 to 1, a considerable amount of expenses will have to be deducted from the prize amount.
What should the player do if he is determined to receive the coveted payment of 35 to 1 and guess the number in roulette without resorting to all kinds of betting systems (which, by the way, are not designed for this kind of bet)? The answer is simple: use special software.
There are many programmes designed to analyse the picture of the game and predict the outcome of each next round. Such programmes are called roulette analysers. Their advantage is that software determines the probability of a particular sector falling out in the next draw based on the received information about previous draws. Ultimately, such programme calculates the mathematical probability for each of 37 sectors of the European online roulette. As a result, the player actually receives a list of numbers with the following information: the sector’s name and the probability of this sector to fall out in the next round. The sector that happens to be at the top of such a list will be the most likely result of the roulette wheel rotation; it seems fair to say that the analyser programme actually guesses the number in the roulette wheel. This process, of course, cannot be called fortune telling in the full sense of the word; the prediction is not based on the player’s intuition, but on the exact calculation of mathematical expectation and probabilities. In order for the forecast to be as accurate as possible, you will need to make a lot of efforts, at least, enter all the results of the previous rounds into the programme memory so that the algorithm can determine the game pattern and some regularities.
Gambling Software Disadvantages
How to guess numbers and win at roulette using these guesses? This question has worried for decades not only ordinary players, but also scientific mathematicians, i.e. specialists in probability theory. Albert Einstein, the famous scientist, once said the only way to win at roulette is to steal the money from the table when the croupier isn’t looking. It is difficult to dispute the opinion of the great scientist: ultimately, guessing the numbers in roulette with an accuracy of 100% in each round is beyond the power of either a person or a computer programme. This, however, is not surprising: if, in order to guess the colour, the programme needs to analyse the probability for only 2 options (red/black), then in order to guess the numbers in roulette, it needs to analyse the roulette wheel numbers in total, that is. 37 possible options at once! This very lack of accuracy is one of the main disadvantages of any gambling software.
No computer programme can give an absolute guarantee of winning at roulette. Besides, it is unlikely that such software will appear in the near future because even the brilliant mathematicians who wondered how to guess the result of the next spin in roulette still have not found the answer. Therefore, choosing a special software for the game, it is necessary to take into account the fact that not even the most advanced and expensive programme will give you the opportunity to make a fortune on roulette or let you know how roulette pays out.
Roulette Algorithm in Online Casino: Most Popular Roulette Numbers
Everyone who has at least once had dealings with roulette in online casino knows that this game of chance is a programme and, accordingly, the result of each spin, i.e. each number drawn out, is just the result of an algorithm. The illusion of absolute randomness of sectors’ falling out is created by a random number generator, that programme kernel which helps to determine the sector where the virtual roulette ball will stop. This suggests that it is possible always to win knowing the algorithm by which the random number generator gives its numbers. Therefore, many players are trying to find out how to calculate the roulette algorithm in online casinos. There are at least two ways for this purpose: to analyse the roulette algorithm manually without resorting to any software, or use special analyser programmes created specifically for roulette in online casinos.
It is important to keep in mind, however, that no strategy or a trick in casino roulette rules guarantees you a 100% win, especially when you play at an online casino. The descriptions contained in this article are for a player's information only, and it's up to them to decide whether to adhere to the best roulette wheel odds or not. Always make sure you play responsibly.
