What Is Volatility in Slots? The SA Player's Guide to Slot Variance
Slot volatility (also called variance) describes how often a slot pays out and how big those payouts tend to be. Low volatility slots pay out frequently but in smaller amounts, while high volatility slots pay out rarely but with the potential for much bigger wins. Volatility does not change how much the game pays overall — that is determined by RTP (return to player) — it only describes the pattern of those payouts.
What is Volatility in Slots?
You have found a slot with a 96% RTP and it looks amazing. You load it up with R300 and within 20 minutes, it is gone. What happened? The RTP looked fine. The answer — more often than not — is volatility.
RTP tells you how much a game pays back over time. Volatility tells you how it pays. And for South African players managing a real bankroll, volatility is often the more immediately important number.
Picture two friends at a braai. One hands out small snacks constantly throughout the day — everyone gets something, nobody goes hungry, but nobody walks away blown away either. The other holds everything back until late and then brings out an enormous spread — most people get nothing for hours, but whoever is still there at the end eats like royalty. That is the difference between low and high volatility slots.
Understanding volatility is what separates a player who blows their budget in 15 minutes from one who plays for two hours, stays entertained, and maybe lands something serious. For more strategy and beginner guides, explore our casino guides hub.
Low, Medium, and High Volatility — What Each One Actually Feels Like
Low Volatility Slots
Low volatility slots are the consistent, reliable option. They hit frequently — often every few spins — with smaller prizes. You are unlikely to see a 1,000x win, but you are also unlikely to watch your entire balance disappear before a bonus triggers.
What playing a low volatility slot feels like: Your balance goes up and down, but gradually. Wins come in often enough to keep your session ticking along. The highs are moderate and the lows are manageable. Perfect for players who want to stretch their bankroll and enjoy a steady stream of small victories rather than praying for one big moment.
Best suited for:
- Players with a smaller bankroll (R100–R300 sessions)
- Anyone grinding through a casino bonus wagering requirement
- Players who get anxious watching their balance drop for long stretches
- Casual players who just want to unwind without being wiped out fast
Examples: Blood Suckers (NetEnt), Starburst (NetEnt), Thunderstruck (Microgaming)
Medium Volatility Slots
Medium volatility sits in the sweet spot — and it is where the majority of mainstream slot releases land. You get a reasonable mix of regular smaller wins and occasional larger payouts. It is balanced enough to suit most playing styles without being too tame or too brutal.
What playing a medium volatility slot feels like: Your bankroll will go through ups and downs more noticeable than low volatility, but you will not spend 45 minutes without a single meaningful hit. Bonus features trigger at a reasonable pace and when they do, they pay something worthwhile.
Best suited for:
- Most players, most of the time
- Mid-range bankrolls (R300–R1,000 sessions)
- Players who want some excitement without the extreme risk of high variance
- A solid default when you are not sure what to play
Examples: Gonzo's Quest (NetEnt), Immortal Romance (Microgaming), Book of Dead (Play'n GO — sits on the medium-high boundary), Reactoonz (Play'n GO)
High Volatility Slots
High volatility slots are the big-game hunters of the slot world. Wins are infrequent, sometimes brutally so — you can spin 200 times without anything meaningful. But when the game pays, it really pays. We are talking multipliers that can reach 5,000x, 10,000x, or even higher on some titles.
What playing a high volatility slot feels like: Tense. Exciting. Occasionally agonising. You can watch R500 evaporate spin by spin and then hit a bonus round that returns R3,000. Or you might not hit that bonus at all. High volatility slots demand patience, a robust bankroll, and a solid ability to absorb losses without chasing.
Best suited for:
- Players with larger bankrolls who can sustain long dry spells
- Thrill-seekers who want the possibility of massive wins over guaranteed small ones
- Short sessions where you are deliberately swinging for the fences
Examples: Dead or Alive 2 (NetEnt), Money Train 4 (Relax Gaming), Razor Shark (Push Gaming), Fire in the Hole (Nolimit City), Fruit Party 2 (Pragmatic Play)
How Volatility Relates to RTP — And Why You Need Both
RTP and volatility are two completely different measurements, but they work together to paint the full picture of a slot's behaviour.
- RTP is the destination — how much the game theoretically returns over millions of spins
- Volatility is the road — whether you get there smoothly, bumpily, or via a near-death experience
A slot can have a great RTP of 97% but brutal high variance — meaning most players will never come close to experiencing that 97% in a typical session. Conversely, a slot with a 95% RTP but low variance will feel more generous in practice because wins come regularly.
The dangerous combination to avoid is low RTP + high volatility: the game pays back less overall and those payouts are sporadic. You are statistically more likely to exhaust your bankroll without ever hitting the big pay moment.
The ideal combination for most South African players is high RTP (96%+) with low or medium volatility — your money lasts longer, the game gives you regular feedback, and you have a fighting chance to land something decent.

Which Volatility Suits Your Playing Style?
Not sure where you fall? Run through this quick check:
Budget Player (R100–R300 per session)
Go low volatility. With a smaller bankroll, high variance slots will statistically wipe you out before the big moments arrive. Low volatility stretches your money, keeps you in the game, and gives you far more spins for your rand. Browse our top-rated SA casinos to find low volatility titles that suit your budget.
Mid-Range Player (R300–R1,000 per session)
Go medium volatility. You have enough cushion to survive the inevitable dry spells, and medium variance slots reward that patience with enjoyable bonus features and decent payouts when they land.
High-Roller or Bonus Hunter (R1,000+ per session)
High volatility opens up. You have the bankroll to absorb the swings, and the potential max-win payouts on high-variance titles are genuinely life-changing at higher bet sizes. Titles like Money Train 4 (max win: 100,000x) or Dead or Alive 2 (max win: 111,111x) are designed for players who can handle the ride.
Clearing a Casino Bonus
Low or medium volatility. Wagering requirements mean you need to turn over your bonus money a set number of times — high variance slots can wipe you out before you clear the requirement. Low volatility slots let your balance breathe while you work through the wagering.
Playing for Pure Entertainment
Whatever you enjoy most. If you love the tension and rare big hits, high volatility might suit you. If you prefer a relaxed session with frequent small wins, go low. Play what you enjoy.

How to Find a Slot's Volatility
Unlike RTP — which providers must disclose — volatility is not always labelled in exact terms. Here is where to find it:
- In-game info screen: Many modern slots (especially Pragmatic Play and Play'n GO titles) include a volatility indicator — usually shown as a bar graph from low to high — on the game's information or paytable page.
- Casino game filters: Some South African online casino lobbies let you filter slots by volatility level. Look for a "Sort by" or "Filter" option in the slots section.
- Provider websites: Major providers like NetEnt and Microgaming often list volatility in their game spec sheets.
- Trusted casino reviews: Our casino reviews include game library and volatility context where relevant. The Springbok Casino review is a useful starting point for RTG-powered titles popular with SA players.
- Play in demo mode first: Load the slot for free before wagering real money. If you go 50+ spins without a win, it is almost certainly high variance. If you are winning every 5–10 spins, you are looking at low variance.
Frequently Asked Questions
What is the difference between volatility and variance in slots?
Volatility and variance mean exactly the same thing — the terms are used interchangeably by players, casinos, and developers. Both describe the risk profile of a slot game: how often it pays out and how large those payouts tend to be. Some providers use "volatility," others use "variance" — do not read anything extra into the choice of word.
Is high volatility better than low volatility?
Neither is objectively better — it depends entirely on your bankroll, playing style, and goals. High volatility gives you a shot at large wins but demands patience and a bigger budget to survive dry spells. Low volatility is gentler on your bankroll, delivers more consistent wins, and suits players who want longer sessions. The "best" volatility is whichever matches how you like to play.
Can a slot have high volatility and high RTP at the same time?
Yes, absolutely — and these are often the most exciting slots available. Dead or Alive 2 has a 96.8% RTP and extremely high volatility. Razor Shark has a 96.7% RTP and high volatility. High RTP means the game returns more money overall; high volatility means those returns are concentrated into infrequent but larger payouts. This combination is popular with experienced SA players who have the bankroll to handle the variance.
Does volatility affect my chances of triggering a bonus round?
Indirectly, yes. In high volatility slots, bonus rounds are typically harder to trigger but pay significantly more when they do. In low volatility slots, bonus features may trigger more often but with more modest payouts. The overall return (RTP) accounts for all of this — it is the pattern of payouts that changes, not the long-term mathematical return.
How much bankroll do I need to play high volatility slots?
A common rule of thumb is at least 100x your bet size as your session bankroll — ideally 200x. If you are betting R5 per spin, aim for R500–R1,000 for a session. This gives you enough spins to statistically reach the bonus features and experience the game properly. Playing a high variance slot with only 30–40 spins of bankroll is how you blow through R150 and see nothing.
Responsible Gambling
Understanding volatility makes you a smarter player — but no amount of knowledge eliminates the house edge or guarantees a winning session. Online slots are games of chance designed for entertainment, and they will always have a mathematical advantage over the player in the long run.
- Decide on a budget before every session and treat it as money already spent on entertainment
- Never increase your bet size to recover losses — chasing is how small losses become big ones
- Set time limits and stick to them; high volatility slots in particular can eat hours while you wait for a bonus
- Play in free or demo mode first if you are trying a new high-volatility title with real money
