Slot volatility explained
Covers the studios that build for the big max win, and the Megaways and new-release rankings.
UpdatedThis page carries figures checked on the date above, and that window has now passed. Studios publish new RTP settings and casinos change their rules: re-check the sources at the foot of the page.
Volatility is the word for how a slot spreads its payouts. A low volatility game pays small amounts often. A high volatility game goes quiet for long stretches and saves most of its return for rare, large hits. Both can have the same RTP.
That's the part worth holding on to. Volatility doesn't make a game cheaper or dearer in the long run. It changes what a session feels like and how likely you are to run out of money before anything happens.
It's also, honestly, a bit of a mess as a published number. Studios rate it on their own scales, aggregators re-rate it, and the figures don't always agree. We don't score volatility in the Spin Score. We show it as a filter, because it's a preference, not a quality.
At a glance
- In one line
- Volatility is how bumpy the ride is: how often a slot pays and how big the payouts are when they come.
- What it doesn't change
- The long-run return. Two slots at 96% RTP cost the same on average, whatever their volatility.
- Our mix
- 3 low, 11 medium, 13 medium-high, 41 high and 37 very high, out of 105 slots.
- The scale problem
- NetEnt uses 0-10, Hacksaw 1-5, Nolimit City uses words like Insane. We map them to one five-step label.
- Pick by budget
- Low or medium for a long, steady session on a small budget; high only if you can afford long dry runs.

What volatility does to a session
Picture two games, both at 96% RTP. On the low volatility one, a run of spins mostly nibbles at your balance with frequent small wins topping it back up. The line on the graph wobbles gently downwards. On the high volatility one, the line drops steadily through dead spins, then jumps when the free spins land, if they land.
Over a million spins those two lines end in the same place. Over 200 spins they can end anywhere.
High volatility is where the giant max wins live. In our data the median max win is 900x for low volatility slots and 17,416x for very high ones. That ceiling comes at a price: most sessions on a very high volatility slot never get near the feature that makes it, and the base game is often a grind while you wait.
Low volatility has its own catch. Starburst's max payout on netent.com is 800x. You won't be bored, but you won't see a life-changing number either. Skip it if that's what you're after.
Hit frequency is not the same thing
A lot of people treat hit frequency as a volatility gauge. It isn't, quite. Hit frequency counts any winning spin, including ones that pay back less than you staked.
Our data shows how loose the link is. NetEnt lists Starburst (low volatility) at a 23% hit frequency and Blood Suckers (also low) at 45%. Nolimit City's Tombstone RIP, rated Insane, sits at 9.08%. Fine, that fits. But among the very high volatility slots where a hit rate is published, the median is 30.0%, higher than the 25.1% median for the high group. Cluster and tumble games pay lots of tiny wins and still hide their real money in the bonus.
So use hit frequency for what it is: how often the screen flashes. Volatility is about where the money sits.
Every studio uses a different scale
There's no industry standard. Here's what our researcher ran into:
- NetEnt prints a 0-10 number on each game page. Starburst is 3.1, Dead or Alive 9.9.
- Big Time Gaming publishes a 0-10 number through playin.com, Evolution's studio site. Bonanza Megaways is 7.4.
- Hacksaw Gaming uses 1-5, and not always consistently: Wanted Dead or a Wild shows 4/5 on its game page while the studio's games list shows five bars.
- Nolimit City uses words. High, Extreme, Insane. Mental is Insane.
- ELK Studios rates games out of 10 on a data sheet. Ecuador Gold is 8 of 10 there; Bigwinboard calls it 9/10.
- Red Tiger shows only a numeric index (30.84 for Gonzo's Quest Megaways), with no label at all.
- Play'n GO lists no volatility on its own game pages; Bigwinboard rates Book of Dead 10/10.
To compare like with like, we map everything to five labels: low, medium, medium-high, high and very high. For NetEnt's and Big Time Gaming's 0-10 numbers the cut-offs are under 4 low, 4 to 5.4 medium, 5.5 to 6.9 medium-high, 7 to 8.4 high, 8.5 and up very high. Where a studio publishes nothing, the label comes from an aggregator and the record says so. Treat any single label as a rough guide, ours included.
Our volatility mix, from the data
Of the 105 slots we score:
| Volatility | Slots | Median max win |
|---|---|---|
| Low | 3 | 900x |
| Medium | 11 | 2,500x |
| Medium-high | 13 | 3,844x |
| High | 41 | 10,000x |
| Very high | 37 | 17,416x |
That's 78 of 105 rated high or very high. It's not our taste showing. It's the market. Most big releases from Nolimit City, Hacksaw, Pragmatic Play and Push Gaming are built around a feature that can pay thousands of times the stake, and that design is high volatility by nature. Nolimit City alone has 9 very high games in our set of 12.
The low end is thin. All three low volatility slots in our data are NetEnt games: Starburst, Blood Suckers and Mega Fortune. If you like that style, our low volatility slots page ranks the best of the gentler games.
How to pick, given your budget
Start with how many spins your budget buys. €50 at €0.50 a spin is 100 spins. On a very high volatility game, 100 spins is often not enough to see a bonus at all. Drop the stake to €0.10 and you have 500 spins, which gives the game room to do its thing.
If you want a long, steady session on a small budget, go low or medium. If you're playing for the chance of a big feature and you've accepted the session will probably end at zero, high volatility is the honest choice. Just don't raise your stake to "make it happen". Bigger stakes don't change the odds of the feature; they only make the dry runs more expensive.
And I'd skip the bonus buy on very high volatility games unless you've read its RTP. On some it's higher than the base game, on some lower. A 100x buy on a 5,000x game is a big bet on one round.
Frequently asked questions
Does high volatility mean a slot pays less?
No. Volatility is about how payouts are spread, not how much is paid back overall. RTP measures the long-run return. A high and a low volatility game at the same RTP cost the same on average over a very long run.
Which is better for beginners, low or high volatility?
Low or medium, usually. Wins come more often, a small budget lasts longer and you get to see how a game plays. Our best slots for beginners list leans that way for the same reason.
Why do two sites list different volatility for the same slot?
Because there's no shared scale. Studios use 0-10, 1-5 or words like Insane, and aggregators re-rate games their own way. ELK's data sheet gives Ecuador Gold 8 of 10 while Bigwinboard gives it 9/10.
Is hit frequency the same as volatility?
No. Hit frequency counts any winning spin, even wins smaller than your stake. A game can have a high hit frequency and still keep most of its return in a rare bonus round.
Can I change a slot's volatility?
Not the game's own. Some slots offer modes or bonus buys that change how the money is spread, and those can come with a different RTP too. Check the rules screen for each mode before using it.
