Slot machines rightfully constitute one of the foundational pillars of online casinos. These casino games provide immense enjoyment and are incredibly diverse and varied, catering to every individual's tastes. They offer a plethora of options to suit a wide range of preferences, ensuring that there is something suitable for everyone.

When discussing online slots, the terms volatility and variance are often mentioned alongside the payout percentage. On this page, we aim to define these terms and explain their influence on casino games. Let's delve into what is meant by a volatile slot machine.

How do online slots work?

To begin with, let's delve into the inner workings of an online slot. Once we grasp the mechanics, we can delve into more advanced concepts, such as understanding variance.

An online slot machine is a traditional game of chance. You set your bet, press the button, and the game commences. On the screen, the lucky symbols spin across the reels and eventually come to a slow halt. You win when multiple identical symbols align on a payline.

The concept of the game is straightforward and thrilling. Nowadays, there are, of course, numerous diverse variations available. Instead of 5 reels, one might come across a square game board where winning symbols tumble down from above into open spaces, or perhaps sideways rotating reels. As previously stated, there is something for everyone here. However, the fundamental gameplay has hardly changed at all.

The random number generator used in casino games

In the realm of traditional slot machines, the outcome of a game was determined by the spinning reels themselves, but in an online casino, this aspect is now merely simulated. The result of a spin is determined by a Random Number Generator (RNG), which generates a random outcome for each game round, subsequently interpreted by the casino software. This simulation accurately replicates where a reel would ultimately come to a halt.

A reliable random number generator is an essential requirement for a reputable online casino. That's why independent testing organizations regularly monitor and license the random number generators used by online casinos. This ensures that the games are fair and unbiased, giving players a genuine chance to win. Without these rigorous checks and certifications, players wouldn't have the peace of mind and trust needed to enjoy their online gambling experience. So, whether you're spinning the reels on a slot machine or playing a hand of blackjack, you can rest assured that the outcomes are truly random and not influenced by any external factors. Join a licensed online casino today and let the fair random number generator determine your fate!

In addition, online casinos record the outcomes of the number generator, ensuring that everything was above board. By doing so, providers guarantee that the delivered results are truly random. This comprehensive approach makes fraud and manipulation virtually impossible, as the licensing authorities also have access to this data. Any irregularities, such as tampered slot machines that refuse to pay out, would be immediately apparent. This meticulous monitoring safeguards the integrity of the gaming experience, ensuring fairness and transparency for all players.

What does volatility and variance mean?

Let's now turn to the main topic at hand: the volatility and variance of slot machines and video slots. These are statistical terms that reflect the long-term behavior of a machine. Volatility and variance are closely connected and are often interchanged in everyday language. In this article, we will be using both terms interchangeably.

In essence, variance provides insight into the extent to which the outcomes of a game round can differ from one another. In a high variance slot machine, the outcome of a game round is particularly uncertain. It is possible that you may not win anything over multiple game rounds, but suddenly you hit the jackpot, which more than compensates for your previous losses.

High volatility slot machines are considered particularly risky. It's easy to find yourself depleting your gaming budget in pursuit of the jackpot, simply because that final stroke of luck eludes you.

On the flip side, slot games with low volatility are known for their frequent payouts, albeit in smaller amounts. Variance and volatility, therefore, are not inherently good or bad, but rather, it depends on one's personal preference and appetite for risk. In a casino offering a diverse range of games, players can naturally find slot machines with varying degrees of variance.

The benefits of high volatility in slot machines.

Take a look at the advantages that high-variance slot machines can offer. If you're a fan of high-risk games with potential for big wins, then you've come to the right place. Let's explore the benefits of these thrilling slots. With their unpredictable nature and potential for massive payouts, high-variance slots provide a thrilling gaming experience like no other. Brace yourself for an adrenaline rush as you spin the reels and chase after those elusive but rewarding combinations. While they may not guarantee frequent wins, the excitement of hitting a massive jackpot is unmatched. Get ready to embark on an exhilarating journey filled with suspense and the potential for life-changing wins. So, if you're ready to embrace the thrill and uncertainty that high-variance slots bring, get started today and see if you have what it takes to conquer these exciting games.

High risk

Many players find that the essence of great excitement lies in taking risks, and this is precisely what a high variance entails. Therefore, those who are fond of daring endeavors will undoubtedly derive immense joy from engaging in casino games with a high variance. It is worth noting that a higher variance always corresponds to a higher level of risk, further intensifying the thrill experienced by players.

Big jackpots

A significant dispersion typically implies that the potential rewards are particularly substantial. A substantial variance often goes hand in hand with a high risk of loss. However, it is also possible to secure exceptionally large sums. For instance, in progressive jackpot slots, the jackpot itself is nearly impossible to crack – yet with a small wager, one can win millions of euros in one fell swoop.

The advantages of low volatility in slot machines

Of course, there are also low-volatility slot machines available. After all, preferences vary, and the top online casinos cater to everyone's tastes. Naturally, these games also come with their own advantages, depending on one's personal preferences.

Manageable risk

With its diminished variance, the risk of the game becomes much more manageable. In these games, one consistently wins smaller amounts that keep them afloat. While in a high-volatility slot, the entire game budget can be lost in an instant, with a low-variance slot machine, there is more time to react to a losing streak. Then, one can either pause the game and take a break or decrease the bet size, further reducing the risk.

Longer gaming fun

When playing an online slot machine with low volatility, one can stretch a small budget for a longer period of time due to the frequent occurrence of small wins. Therefore, players can enjoy their money for an extended duration. This is why these games are particularly popular among beginners. It's important to note that these games don't offer substantial jackpots, but most players aren't seeking that anyway. They are more interested in the entertainment value and the ability to play for an extended period without risking too much.

Where can one find the variance of a slot machine?

Finding information about the variance of a game is often not as easy as checking the payout rate of an online slot, which is usually visible on the casino's homepage. This is mainly because calculating this value can be quite challenging.

Depending on the provider, consulting the game manual or the manufacturer's website can be helpful. Review sites are also almost always a reliable source for information on the variance of an online slot. In general, it can also be stated that the higher the potential jackpot, the higher the usual variance of a casino game. By and large, the level of variance in a casino game tends to increase as the potential main prize rises. It is worth noting that examining the game instructions or the manufacturer's website can be beneficial depending on the provider. Additionally, review sites often prove to be a valuable resource for understanding the variability of an online slot. Moreover, it is generally valid to assert that a casino game's variance is typically higher when the potential jackpot is greater.

Debunking Myths and Facts about Slot Machines

It is worth mentioning at this point the various myths surrounding slot machines and debunking them if necessary. There is no need to believe in the following things:

Slot machines only pay out when a certain amount has been lost beforehand.

A widely spread misconception is that slot machines are programmed to pay out only when the casino has made enough money beforehand. This is, of course, nonsense. Each game round is, in fact, centrally stored and evaluated by independent auditing organizations. Any irregularities would be immediately noticed here.

The auto-play feature results in lesser winnings compared to manually initiating a game round.

This is all nonsense. The perception might be distorted by the Auto Play feature, which accelerates the pace of gameplay, allowing for more rounds to be played quickly. One can actually lose their money in a shorter amount of time. However, this is due to playing more spins than would be possible manually. Furthermore, unlucky streaks are particularly memorable. After all, if someone wins while using Autoplay, they are unlikely to attribute their success to the Autoplay feature.

Spielautomaten folgen bestimmten Mustern, die man erkennen und nutzen kann.

Unfortunately, that is not true. While recognizing certain patterns may theoretically be possible with mechanical slot machines, it is certainly not the case with online slots. A certified random number generator produces completely arbitrary results that do not follow any logic and cannot be predicted. Neither the player nor the manufacturers themselves can foresee these outcomes.

One can manipulate online casino games using specialized hacking software to ensure guaranteed winnings.

This is simply erroneous. These manipulations fail on multiple fronts. Firstly, one would have to gain access to the casino servers, which are well protected against such attacks. Secondly, such manipulation should go unnoticed. However, since every game round is recorded and a streak of wins would immediately raise suspicion, one should not place any trust in these promises.

Instead of resorting to these alleged casino hacking programs, one runs the risk of becoming a victim themselves. Fraudsters can gain access to your computer in this manner, potentially infiltrating your casino account or even your bank account. We hope we don't have to spell out how badly this can end...


Besides the probability of winning and the payout rate, volatility and variance are crucial statistical values in casino games. They not only aid in comprehension of the games but also serve as a pivotal factor in the development of an effective gameplay strategy. These statistical measures play a significant role in understanding and strategizing while engaging in casino games.

When it comes to an online slot machine, there are many other characteristics and features that these values do not capture. If you want to know which games are especially fun, you have no choice but to try them out for yourself. Whether you prefer high or low variances ultimately depends mainly on your own playing style.
