Slot volatility, also called variance, refers to the level of risk associated with a game. It determines both the frequency and size of the payouts, shaping your gaming experience by influencing the length of your sessions and the bankroll required to sustain play. Generally, volatility is classified into three categories: low, medium, and high.

This guide clearly explains what volatility means, how it affects your gameplay, and how to select slot games best suited to your playing style.
Volatility is often mistaken for other slot features, leading to common misconceptions that can affect how games are chosen. The following section outlines how it differs from seemingly similar concepts.
RTP and volatility are two distinct aspects of how a slot machine operates, although they are often confused. RTP, or Return to Player, is a long-term average that reflects how much a game is expected to return to players over time. For example, a slot with a 96% RTP is expected to return $96 out of every $100 wagered when played over a long timeframe. This figure is theoretical and doesn’t guarantee a specific outcome in any single session.
Volatility, by contrast, refers to how those returns are distributed throughout gameplay. A low volatility slot may produce frequent but smaller returns, whereas a high volatility slot might remain inactive for several spins before delivering a much larger result. Two games can have the same RTP but behave very differently depending on their volatility, which is why understanding both is essential when evaluating a slot.
In the context of slots, volatility and variance are often used interchangeably. Different developers or casinos may favour one term over the other, but both refer to the same concept. Whether a slot is labelled "high variance" or "high volatility," it's referring to the same level of risk and reward.
As mentioned earlier, most slot games fall into one of three volatility categories: low, medium, or high.
Low volatility slots are structured to deliver returns more frequently, typically in smaller amounts. These games often produce results in the range of 2x, 5x, or 10x the stake, while larger jackpots are uncommon.
Maximum returns may fall between 200x and 500x the original bet. While the top end of potential outcomes is limited, the rate at which a bankroll changes tends to be slower than in higher-risk games.
These titles are built to sustain longer sessions with minimal fluctuation, offering more consistent pacing even if individual outcomes remain unpredictable.
Medium volatility slots sit between low and high volatility games, offering a moderate balance of return frequency and outcome size. Results occur less frequently than in low-volatility titles but more often than in high-volatility ones, with potential returns that typically fall into a mid-range bracket.
The return pattern in these games limits sharp fluctuations while still allowing for outcomes that carry more weight than those found in lower volatility slots. The risk level remains moderate, avoiding the prolonged quiet stretches and dramatic swings associated with high volatility games.
High volatility slots are designed to produce fewer returns, often spaced out over longer intervals. Extended periods without any results are common, and it’s not unusual for these games to go through dozens of spins without triggering a return. When potential returns do occur, they are generally at the higher end of the scale compared to low or medium-volatility games.
These titles often feature high-impact elements, including large multipliers, extended bonus rounds, cascading reels, or other mechanics that can deliver substantial outcomes under specific conditions. Because returns are less frequent, the pace of bankroll depletion can be sharp during unfavourable sessions.
Managing funds carefully is particularly important in high volatility games (covered in more detail in the Bankroll Management Strategies by Volatility section), given the irregularity of results. These slots are typically used in scenarios where absorbing longer streaks without returns is financially and psychologically manageable. Without that flexibility, the overall nature of play may be more volatile than desired.
Volatility influences how a slot game unfolds during play, shaping the tempo and structure of its features. In low volatility slots, features like respins, mini bonuses, low-value symbol combinations, and frequent base game hits tend to appear in quick succession. This leads to shorter gaps between events and a rhythm that feels consistent and responsive.
High volatility slots are built differently. Features such as bonus rounds, multipliers, jackpots, or symbol combinations with high returns are programmed to appear less often. As a result, these games create longer pauses between meaningful moments, increasing suspense and producing more dramatic spikes when events do occur.
Medium volatility slots strike a midpoint. The timing and impact of features are more spread out than in low-volatility games. However, they still arrive often enough to avoid the extended quiet stretches typical of high-volatility designs. This balance gives each game a more varied but manageable pace, contributing to a less predictable yet steady overall flow.
Each volatility level suits different types of playstyles based on bankroll size, risk tolerance, session expectations, and preferred game tempo. Understanding these distinctions can help align a slot’s structure with personal preferences and playing habits:
Understanding how to identify a slot's volatility can help set expectations around return patterns and session pacing.
Slot volatility is not always immediately visible, but developers often provide indicators that reveal a game's risk level. Many titles are labelled with terms like “low,” “medium,” or “high” volatility (or variance).
Others use numerical scales, commonly ranging from 1 to 5 or 1 to 10, with higher values corresponding to greater volatility. These ratings are typically displayed in the game's paytable or information panel, which is usually accessible via the "i" icon.
When a clear volatility rating is not provided, certain in-game elements can offer clues. Games that advertise very high maximum wins, particularly those exceeding 5,000x the stake, often fall into the high volatility category.
Compared to that, titles with smaller maximum wins tend to operate at lower volatility levels. The spread between the lowest and highest-paying symbols also provides insight. Larger gaps often indicate a need for occasional large returns to offset frequent low-value outcomes.
Volatility also becomes clearer through direct game testing. In demo mode, tracking return patterns over a sample of 100 to 200 spins may reveal behavioural trends. Again, infrequent but high-value returns generally suggest high volatility, while regular small outcomes point to a lower volatility profile.
Combining this with published reviews, player feedback, hit frequency data, and return distribution patterns can help further clarify a game’s volatility characteristics.
The following sections highlight popular slot titles that reflect each volatility category:
These titles closely reflect the qualities typical of low volatility design:
The selections below reflect typical examples of medium volatility slots.
The following titles represent examples of high volatility slot design.
Volatility in mobile slots works precisely the same as it does on desktop. The game’s payout pattern, risk level, core mechanics, and overall volatility don’t change just because you’re playing on a phone or tablet. Whether it’s low, medium, or high volatility, the mechanics are identical, which means the same reels, the same bonus features, and the same odds. The only difference is the screen size and layout, which game developers design for touch controls and smaller displays.
Even so, the way you interact with mobile slots can affect your overall gameplay. Mobile play often means shorter, more casual sessions, which can feel different depending on the level of volatility. A high volatility slot, for example, might feel more punishing during a quick spin session if you hit a cold streak. Low volatility games may suit mobile play better, offering steady results in short bursts.
Bonus features contribute to a slot’s volatility based on how they are built into the game’s payout structure. While some of this has been noted in earlier sections, it’s worth reiterating how volatility often concentrates potential into feature rounds, especially in high volatility slots, where the base game remains relatively quiet. Features like multipliers, locked wilds, expanding reels, symbol collection mechanics, or progressive jackpots (discussed in the section below) are designed to deliver outsized outcomes but appear sparingly to preserve risk.
In lower volatility games, bonus elements tend to be lighter in impact and more regularly available. These features are often integrated to maintain a consistent pace of returns rather than to deliver major spikes. The balance between frequency and impact of a slot’s features plays a direct role in how its volatility is defined and felt during play.
Progressive jackpot slots are inherently high in volatility, as a portion of each wager is diverted to a growing jackpot rather than distributed through regular base game returns. This allocation reduces the frequency of smaller wins and extends the intervals between outcomes.
Network-linked progressives, which pool contributions from multiple casinos, introduce even higher volatility. The jackpots can grow to significant levels, but the odds of hitting them are extremely low, and regular returns are less common. Local progressive slots found in New Zealand casinos tend to be less volatile by comparison. Smaller jackpot pools allow for a more balanced distribution of outcomes, though volatility remains high relative to non-progressive titles.
Regardless of the format, progressive games typically demand a larger bankroll to sustain prolonged play through extended losing streaks.
The following strategies outline how bankroll management should adapt across different volatility levels.
Demo versions run on the same software and follow the same mathematical structure as real-money slots, so volatility remains consistent across both formats. The outcomes and frequency of returns don’t change based on whether you’re playing with virtual credits or actual funds.
Still, demo play can give a misleading impression of volatility. Without financial risk, it’s easier to overlook the stress that long losing streaks in high volatility games can create. Real money sessions often bring added pressure that influences decision-making and risk tolerance.
When switching to real money play in New Zealand casinos, carry over the same discipline used in demo mode. The volatility remains the same, but responses can shift when real stakes are involved.
Here are answers to common questions about slot volatility, covering how it works and what it means in practice:
Low or medium volatility slots suit beginners, as they offer more consistent pacing and require less risk tolerance.
Check the game’s information panel or paytable for a listed volatility rating, compare maximum returns, test the game in demo mode to observe return patterns, or consult expert reviews for further context.
Large wins are uncommon in low-volatility slots, as maximum returns typically range between 200x and 500x the stake. These games prioritise consistency over high-value outcomes.
Yes, volatility remains the same in both demo and real money modes. The mechanics and mathematical models are identical across versions.
High volatility slots commonly played in New Zealand include Dead or Alive 2, Money Train 2, and Bonanza.
Slot volatility is a term used to describe how often and how much a slot game will pay out. The Return to Player (RTP) percentage is an average of how much you can expect to have returned over time from each bet you make, worked out over millions of plays.
Generally, no. However, the casino developer Wazdan produces games that have changeable variance. There may also be some symbols or bonus features that can temporarily alter a slot's prize mechanics.
Most reputable casinos will include all of a game's details on its own page. You might also find the volatility level included in a slot's manual. This can usually be found somewhere on the game screen. If you can't find it, large jackpots often indicate high volatility and vice-versa.
Yes, as they may have a maximum bet stipulation for access to the jackpot. Also, they pay out at a much slower rate than low-variance games.
This is entirely a choice you need to make, as a player. Your chances of winning huge prizes are naturally slim - but if you really want the biggest jackpots, you'll find them in high-volatility games. Best to know your bankroll and preferences before indulging in high volatility slots.
Volatility can be controlled to some extent with an appropriate bet size. To maximize your chances of a large jackpot win, you can stake the maximum amount possible before every spin. This is usually in the region of $100.00 - $200.00.
Yes. Highly volatile games and progressive jackpot slots will usually produce better results with larger bets. Mind you, while those wins may be potentially larger, you'll need a bigger bankroll to keep the high betting rolling until one hits..if it does at all!
Usually, yes. Progressive jackpot games like Mega Moolah may only pay out their main prize once or twice a year. This makes their volatility a difficult thing to judge.
Yes. Low volatility slots pay out little and often, while high volatility games have huge prizes but little interest in giving them out.
The gambler's fallacy can play a role in high-volatility slots. Just because a slot machine hasn't paid out in a while, there's no guarantee that it will on any future turn either.
