Slot games found in online and social casino sites have various specifications and figures that show how they operate and what you can get from them. Almost every title has a specific configuration of reels and rows, number of winlines, top win amount, minimum and maximum play limit, RTP percentage, and volatility.

But what is slot volatility? We often hear of low and high volatility slots, but many players don’t fully understand what these descriptions mean. This characteristic dramatically affects how often you will get rewards from playing and is crucial to understand, so keep reading this guide to learn all you need to know!

Slot Machine Volatility Explained

Slot volatility determines the frequency of wins in online and sweeps slots. The volatility index is essentially a formula or measurement of risk, as it explains how often you win and lose and what the size of your wins might be on average. 

This shouldn’t be confused with the game’s RTP, which tells you the percentage of the played amount the sweepstakes casino will return to players. However, both are crucial for understanding how rewarding a slot machine can actually be. If you need a clearer definition of that figure, here is a full guide to how RTP compares to slot volatility.

Volatility can be low, medium, or high. Each option affects the game differently, with specific strengths and weaknesses. We’ll focus on each in the next section.  

It is worth mentioning that game providers sometimes mention low-to-medium or medium-to-high volatility, as it is difficult to classify some slots within one of the three default categories. You’ll even hear about very low and very high volatility. 

Also, bear in mind that some use the term variance instead of volatility, but both words refer to the same concept.

What Are Low Volatility Slot Machines?

Low volatility slots have frequent but low wins. In other words, you’ll match combinations frequently, but most of these will result in smaller coin amounts. 

This might also mean that you’ll often get wins lower than your original play, but they will still come regularly with some variation in size. That way, you’ll eventually leave the play session with more coins than you started with.

What Are High Volatility Slot Machines?

High volatility slots are the exact opposite of slot machines with low volatility. In other words, their wins are infrequent but often very big. Naturally, it is not a given that your returns will be large per se, but they will, on average, be higher than the ones in low and medium volatility slots

Also, keep in mind that while playing free high volatility online slots, you are likely to encounter long dry periods, but the game’s jackpots with massive rewards will surely make the wait worthwhile. 

What About Medium Volatility Slot Machines?

Medium-volatility slots sit somewhere between the two categories mentioned above, meaning that their wins are fairly regular, and the coin rewards are medium-sized. 

Many of the best games, such as Zula slots or those on other social platforms, fit this description because their players can expect both regular and high wins. Only medium-volatility slots can offer both regular and high wins more often than other options can.

Importance of Volatility in Slot Games

The primary reason to pay attention to the volatility level in slot games is that it influences how often wins occur. However, that is not all. It also matters because specific volatility indexes are ideal for particular types of players. 

High volatility is more suited for risk-takers and adrenaline-seekers. It can be very exciting, as the chances of getting massive wins are the highest here. However, you also need to be ready for dry spells, meaning wins might not come for several spins.

On the other hand, the best low volatility slot machines are more suited to casual gamers with limited budgets. There is not much excitement here, as big wins are rare, but if stability attracts you to slot games, low volatility will be ideal for you. This is also why volatility is an important part of the best strategy for casino slots, since it helps you pick games that match your preferred risk level.

High Volatility vs Low Volatility: Pros and Cons

The main difference between high volatility and low volatility in slot games is risk versus reward. High volatility games usually offer larger but less frequent payouts, making them better suited to players chasing bigger wins. Low volatility games provide smaller but more regular payouts, which can suit players who prefer steadier rewards and longer gameplay sessions.

Is high or low volatility better? This is one of the most common questions players have about slot volatility. The good news is that there is no answer to this question, as both types have their strengths and weaknesses. That choice becomes even easier once you understand what denomination means in slots and how play size affects session length.

High volatility slots are not necessarily better than low volatility ones, unlike high RTP slots. To clear things up, here is an overview of the pros and cons of both, starting with slots with low volatility:

Low volatility slots
ProsCons
Very frequent winsLow rewards on most hits
Rare dry periodsSmall jackpots

Now, let’s check the characteristics of high volatility slot games:

Ideal option for adrenaline-seekers

How to Determine Which Slot Machine Volatility is the Best for You

To determine what slot volatility is ideal for you, you must ask yourself what type of playing experience you want. As stated, the best high volatility slots are more suited for adrenaline-seeking gamers, while low volatility online slots are primarily made for casual players looking for an easy-going experience and those playing with lower coin amounts. 

Naturally, if you can’t see yourself in either of these categories, medium-volatility slots are likely ideal for you.

Overall, it is best to consider different options before you start playing. If you’ve claimed a few promotions and are ready to try things out, you can experiment with games of all volatility levels and see which level suits you best.

Impact of Volatility on Slot Wins

Volatility has a big impact on slot wins, but mostly in terms of their frequency, whereas their sizes may differ. After playing several sessions in both types of slots, you might end up with the same number of coins, as volatility is not the only factor impacting your returns.

Even though volatility affects the wins in a slot game, that doesn’t mean you need to adjust your plays based on the slot machine volatility chart. You should still determine the amount you’ll play with based on how many coins you currently have and are willing to use.

It is also unnecessary to use smaller plays in high-volatility slots or larger plays in low-volatility slots. This will not lead to bigger wins, as the outcomes of all slot games are still completely random. 

FAQs

How to find low volatility slot machines?

The easiest way is to google the best low volatility slots. However, online and social casinos often display the volatility levels of their games and provide categories or a dedicated list of low volatility slot machines in their libraries. The same can be true for medium and high volatility slots. 

How do I determine the volatility of a slot game?

You can’t determine the slot’s volatility on your own, as it would only be guesswork. However, game providers typically state the slot machine volatility index within the game’s Settings, and you can also find this information online. Moreover, social casinos often display a slot’s volatility in its description within the site’s library. 

What does low volatility mean in slots?

Slot machines with low volatility are slots where wins are frequent but typically low. This is not a rule but just an average, so you can still have bigger wins and long dry periods. 

What does high volatility mean in slots?

Slots with high volatility are online slot games with infrequent but bigger average wins. These large wins can also be jackpots, but not necessarily. Naturally, high volatility also means that you are more likely to encounter dry spells than in medium- and low-volatility slots.
