If you have seen terms like “volatility” or “variance” when browsing online slot games, you are not alone in wondering what they mean. Although it can sound technical, knowing about volatility could help you understand how slot games are designed.
In the sections below, we’ll discuss what volatility means, how it works, and why it matters when playing online slots. Read on to learn more.
What Does Volatility Mean on Slots?
Volatility describes how a slot game may pay out over an extended period. It does not relate to the number of reels or how much you potentially bet. Instead, it refers to the size and frequency of potential payouts across many spins.
-
Low volatility slots may offer smaller wins that occur more frequently.
-
High volatility slots may offer larger wins, but these may appear less often.
-
Medium volatility sits between these two types, with a balance of smaller and larger wins.
You can usually find information about a slot’s volatility within the game’s help section.
UK slots use a certified Random Number Generator (RNG), meaning each spin is independent. Volatility gives an overview of how results may be distributed over time but does not affect individual outcomes. Players should always remember to gamble responsibly and within their means- never wager more than you can afford to lose.
How Volatility Affects Slot Gameplay
Volatility could influence how your balance might change during play. Low volatility games may produce more regular returns, which can keep your balance steadier. However, the wins tend to be smaller.
High volatility games may involve longer gaps between wins. When wins occur, they might be larger. This can result in more variation across sessions.
Medium volatility slots can show a mixture of both types. The way wins are spaced out depends on the design of the individual game.
Slot features such as cascading reels or Megaways do not change a game’s volatility. These features alter how wins appear but the volatility remains fixed and is part of the game’s underlying setup.
If you prefer a certain type of playing experience, setting clear limits on time and spend might be a good idea to help you stay within your personal comfort zone.
What Are the Different Types of Slot Volatility?
Most online slot games fall into three main categories of volatility: low, medium, or high. You may also see variations such as “medium-high” or “medium-low”, which describe games that sit between the core categories.
-
Low volatility: Games designed for frequent, smaller wins. These may appeal to those who prefer more consistent results.
-
Medium volatility: Offers a blend of both smaller and larger wins. These games may show more variation between sessions.
-
High volatility: These games may feature larger wins but these occur less often. Some players may choose these if they are comfortable with longer gaps between payouts.
Volatility is usually listed in the paytable or help section of each game. If it is not clearly stated, the way wins occur during gameplay may give you an idea of the type of volatility.
Comparing High and Low Volatility Slots
High and low volatility slots can offer very different types of gameplay. In high volatility games, you may see long periods without a win, followed by larger payouts. This can lead to larger changes in your game balance across time.
Low volatility slots may show more frequent wins, although the amounts tend to be smaller. This can result in steadier movement in your balance during a session.
You can usually find details about volatility and RTP in the game’s help section or paytable. If not, trying demo versions of slots could help you get a feel for how the game behaves.
How To Identify Slot Volatility Levels
Understanding a game’s volatility can help you set realistic expectations for how it might play out over time. There are a few ways to identify a slot’s volatility:
-
Paytable or help section: This is where many providers display volatility information.
-
Developer or review sites: Some providers include this data on their websites, or you can check licensed review platforms.
-
Demo versions: Free versions of the game can give you insight into how frequently and how much a game may pay out.
Games with higher jackpots or rare bonus features can indicate high volatility. Frequent small wins may suggest a low volatility game. These signs may help you assess the game if no clear volatility label is provided.
Volatility and RTP Compared
Volatility and RTP are two separate concepts that work together to shape a slot game’s design. RTP, or Return to Player, is the theoretical percentage that a game returns to players over a long period. For instance, an RTP of 96% suggests that over time, £96 is returned for every £100 played. This figure is based on extensive simulations and is reviewed by approved testing agencies.
Volatility refers to how that return is distributed. Two games with the same RTP can behave differently based on their volatility setting.
Most UK-licensed operators display RTP in the game’s rules or information menu. Volatility may also be included, though this is not a regulatory requirement. Independent review sites may also list these figures if they are not shown in the game itself.
Volatility is built into the game’s structure and remains fixed. It does not change between features or bonuses.
