Volatility is a characteristic of casino slots that determines how they pay. This guide explains exactly what the term means and how it all works. We’ll also reveal some of the most popular high and low volatility slots

Key Beats

  • Volatility means unpredictability. In slots, volatility is an indicator of how winnings are distributed, ranging from smaller and more frequent wins to bigger and less frequent wins.
  • You can’t measure, change, or interfere with slot volatility. To know how volatile a machine is, simply conduct an online search or look for a slot volatility chart. Additionally, the maximum win can reveal the volatility of a slot machine.
  • Slot machines are categorized into three groups based on volatility. There are high-volatility slots, medium-volatility slots, and low-volatility slots.

What Is Volatility?

Volatility is a measure of unpredictability or risk. Sometimes called “variance,” it describes how much something is likely to fluctuate, such as the price of stocks and commodities.

Cryptocurrency is the perfect example of a highly volatile asset. Bitcoin often loses 5% of its value in a few hours before surging back up in price just days later. 

When investing, low-volatility assets are considered safe. They might not yield as much profit in the long term, but they’re predictable, and you’re unlikely to lose everything.

Highly volatile investments, however, are seen as more of a gamble. You could make a lot, but the risk of losing your capital is far greater. 

What Does Volatility Mean in Slots?

Volatility’s meaning in slots describes how real money slots pay out over time. If the return-to-player rate (RTP) reveals the amount we can expect to win, slot machine volatility indicates how it’s paid out.

Slots Volatility Example

Imagine spending $100 on a slot at $1 per spin. Your first 99 turns all lose, but you win $96 on the 100th spin. That’s a 96% return-to-player rate for the session.

Now let’s try a different machine. This time, your 100 spins produce a relatively even mixture of 52 losing spins, with 48 prizes of $2 each. That’s a total payout of $96, also a 96% RTP.

Although both slots paid the same amount, the second produced a consistent string of smaller wins. This is how low-volatility slots work.

The first game was highly volatile, with long losing streaks and bigger-than-average prizes.

Calculating Volatility

Unfortunately, there’s no consistent way to measure the volatility of slots, and each game developer uses its own scale and terminology. 

Pragmatic Play, for instance, rates games numerically out of five. But Nolimit City uses terms like “extreme” and “insane” to rate the volatility of its slots.

However, all developers employ third-party testing agencies, such as GLI or eCOGRA, to audit their games and prove their fairness. As part of the process, millions of spins are simulated to determine key statistics, such as the RTP and maximum potential payout. 

This also gives an indication of a slot’s volatility, measuring the percentage of spins that produced a win.

Types of Volatility in Slots

Although the industry uses inconsistent terms, the volatility of individual slots can still be categorized into three broad groups: low, medium, and high. You may also see the intermediate terms ‘low-medium’ and ‘medium-high’ volatility.

Let’s take a closer look at what you can expect from slots within each category.

High Volatility Slots

The best online casinos offer hundreds, if not thousands, of slot machines, covering a wide range of volatility levels. Those at the higher end of the scale share many similar features. Expect bigger maximum potential payouts, fewer frequent prizes, and the possibility of long losing streaks, for instance.

On the other hand, these games are among the most popular among thrill seekers, who chase big wins. Let’s take a look at some of the best slots with high volatility.

Low Volatility Slots

In contrast to their high volatility counterparts, low-variance slots are far more predictable. You can expect a fairly steady flow of smaller prizes without enduring stressful dry spells.

As a result, they’re some of the best slot machines to play if you’re new to gambling or have a smaller bankroll. However, you won’t see the enormous potential wins offered by higher variance games. Here are some of the most popular low-volatility slots.

Top Tips on Slot Volatility 

When selecting the best slot machine to play at the casino, volatility is one of the most crucial factors to consider. Keep the following tips in mind.

💡 Understand what volatility means: There’s no point even thinking about volatility until you know what it means. Highly volatile games pay less often, with hit rates lower than 15%. Low-volatility games could pay out on up to 50% of spins.

💡 Look for volatility clues. Many developers don’t announce the volatility of games. If they do, it’ll be with vague terms that aren’t consistent across the industry. However, low maximum wins and RTPs typically indicate low volatility. The reverse is also true. You can also search online for a slot machine volatility chart to get information. 

💡 Manage your bankroll. Volatility dictates the bankroll required. You might get away with smaller sums when playing low-volatility slots. However, the riskier a game is to play, the more carefully you must manage your bet sizing and budget.

Conclusion

It’s hugely important to look into the differences between low-volatility and high-volatility slots, as they can have an impact on the potential money you might win. High-volatility slots are particularly risky if you don’t know what you’re doing.

Read this guide on slot volatility explained in simple terms carefully, and understand what volatility means before playing. Then, choose a slot whose volatility aligns with your level of risk tolerance and bankroll.

FAQs

What is the best volatility for slots?

Volatility is subjective. If you’re a thrill-seeker who loves chasing big wins, high-volatility games will be the best slots for you. But if you’re risk-averse and prefer smaller, more predictable returns, low-volatility slots offer a better experience.

Is low volatility good in slots?

Low-volatility slots are great for anyone with a relatively small bankroll, as there’s significantly less risk involved. They also provide the perfect introduction for new players who don’t yet have much experience with slots. However, they’re not good if you’re chasing massive payouts.

How does slot volatility differ from RTP?

Slot volatility refers to the frequency and how a slot machine pays out, while RTP refers to how much a machine pays out to winners over a period of time.

How to determine the volatility of a slot machine?

A simple online search can reveal the volatility of a slot machine. Likewise, you can check the maximum win for an indicator. Low maximum wins typically indicate low volatility, and vice versa.

What is volatility in slots?

Volatility, often referred to as “variance”, reveals how slots pay their prizes. Low-volatility slot machines provide frequent payouts – up to 50% of spins – but prizes tend to be small. Higher volatility games promise large potential wins, but you may need to be patient.

What does high volatility mean in slots? 

High volatility slots are riskier to play, as they’re unpredictable. They can produce long runs without a win, before suddenly dropping a sizeable prize. In contrast, low-volatility games are much more predictable, paying smaller returns more consistently.
