Video slots are some of the most popular games to play at online casinos. All of these slot games come with unique themes, special features, and gameplay mechanics, and all slots have their own variance, a mechanic which determines how payouts are handled within the game. Discover the difference between low and high volatility slots and what the best high and low variance slots are in this article.
What Is Variance In Slots?
As we mentioned above, variance is a mechanic in both off and online slots which determines how payouts are handled within games. Video slots can either by low volatility or high volatility, and each changes the size and frequency of payouts, affecting how much and how often you can trigger wins. Luckily, the difference between low and high variance slots is easy to understand; wins in low variance slots are usually smaller in size but happen frequently while slots with high variance are bigger in size but happen less frequently.
A slot’s volatility is usually a key factor in determining what slot a player might want to play. The reason for this is because low volatility slots can provide you with more playtime on a smaller budget while making frequent small wins, making them great for anyone new to video slots.
Compare this with high variance slots which require more funds since you’re less likely to make wins and therefore need to wager more spins and spend more time playing. MegaWays games are usually of high variance, and slots of high volatility are generally deemed to be a bit more “risky” to play and aimed at more experienced players.
Can You Measure High And Low Slot Variance?
When people learn about slot variance, one of the first questions they ask is whether it’s possible to measure a slot’s volatility. Generally speaking, you can’t measure the variance of a slot, but many online casino game developers like NetEnt, Play’n GO, and many others share details about the variance of certain games. There are also many websites which detail a slot’s variance using information from developers, but you usually cannot find variance information within a game or at an online casino, unlike RTP rates.
What Are The Top Low Variance Slots?
As we mentioned above, low variance slots, also known as low volatility slots, are usually better for beginners or casual gamers since they are of low risk and offer low rewards. There are hundreds of low variance slots, some of which have gone on to become hugely successful. If you’re looking to play a low volatility slot, check out our recommendations below:

Are There Slots With Medium Variance?
When you search for information on slot variance, you’ll find that most websites only discuss high and low variance. However, there are hundreds of video slots which are of medium variance, which is essentially a mixture of both low and high volatility. These slots usually do not fit under the definition of low and high variance slots and generally balance the size and frequency of their wins to provide players with a more basic experience that can occasionally trigger bigger wins.
However, most people tend to opt for either low or high variance as they’re somewhat more predictable and easier to understand, offering either lots of small wins or a few big wins.
Adjusting Slot Volatility – Can You Do It?
A new trend within the online gambling industry has seen some game developers launch mechanics which allow users to adjust the volatility of their games, allowing them to set the size and frequency of wins to their preferences. At the time of writing, Wazdan is one of the few developers to offer this customisation through its Unique Wazdan Features.
Wazdan’s Volatility Levels
Wazdan’s Volatility Levels tool allows players to modify their win size and frequency at any time while playing a slot. As explained by the game developer, users will be able to choose between high and low volatility or use the game’s Standard mode, which balances out win size and frequency.
Volatility Levels is one of the many unique features Wazdan has launched for its game, allowing users to customise them to match their preferences. Other features include Ultra Fast Mode which boosts gameplay, Ultra Lite Mode which omits certain animations to decrease load time, Big Screen Mode which offers a wider look at the slot’s reels. There are plenty of others available and you can read all about the developer’s special features in our Wazdan slot guide here.
Summary: Is Better To Play High Or Low Variance Slots?
Now that you know about the different types of slot variance, you’ll need to think about whether or not you should play low or high variance slots. While both offer exciting gameplay and chances to make wins regardless of their size, you’ll need to have a think about what variance suits your needs and preferences, and this can change regularly.
If you’re on a tight budget and are looking to have some casual playtime, low variance slots will be better suited for you. But if you’ve got a wider budget and are looking for a chance to make bigger wins, you may want to try out high variance slots instead.
Regardless of variance, all video slots are fun to play and you shouldn’t only select a video slot based on its variance, it’s important that you also enjoy the theme and check reviews to find a slot with special features that you enjoy and, ultimately, a game that provides you with the most entertainment.
