The 6 Slots We Feel Are The Most Volatile

Big Risk, Even Bigger Rewards

We've all been there: it's 2am on a Friday night and you're spinning the reels, waiting with bated breath, crossed fingers, (and toes) for a slot to finally spit out the bonus features.

Before you know it, you're £200 deep and still stuck in the base game with nothing to show for it except a big fat “-” on your balance. 

This variance is all part of the fun, though, and high-volatility slots, in particular, are a special breed, keeping you hooked on the off-chance that the next spin just so happens to be the one that pays out the big bucks. 

If you enjoy online slots that test your patience and drain your balance, but are still a fun yet wild ride, you're in the right place.

Let's break down the six slots we feel are the most volatile. 

1. San Quentin 2: Death Row

One studio that'll always be associated with high-volatility slots is Nolimit City, who made a name for themselves by pushing the boundaries of what slots can be.

While their themes are definitely not for the faint of heart, their maths models are bound to get the cortisol pumping, since it's both extremely volatile and, at (rare) times, highly lucrative.

This means you never quite know when it's going to be in a giving mood. 

A great example is San Quentin 2: Death Row, the sequel to one of their flagship titles, San Quentin, which amplifies the original's features like it's on the electric chair.

This slot can produce six figure wins, up to 200,000x bet, to be precise. With features like xWays, Enhancer Cells, Jumping Wilds, and Green Mile Spins elevating the gameplay, you won't want to drop the ball (or the soap) with this one.

2. Tombstone Slaughter

With their highly volatile maths models, Nolimit City bonus rounds feel nigh impossible to get into without the xBet Bonus Buy feature. 

Their xSeries, or xMechanics, have almost become a brand of their own, and a game that features these in spades is Tombstone Slaughter, the sequel to Tombstone RIP and Tombstone: No Mercy, as it follows El Gordo's daughter and her quest for vengeance.

These xMechanics like xNudge Wilds and xSplit create a recipe for a volatile slot that'll either blow your head clean off or leave you jumping for joy, depending on how lucky you are.

There are frequent dry-spells between payouts and xRIP makes it hard to claw back even the tiniest of wins if it's below your original bet amount. 

It goes without saying that Tombstone Slaughter is their most volatile slot yet, boasting a 500,000x max win potential, higher than any other online slots on the market, even many progressive jackpots. 

Don't get your hopes up, though. The max win probability, according to NLC themselves, is a one in 189 million. So you're more than likely to feel El Gordo's daughters boot up your backside than hit it.

3. Huff n' Even More Puff

This Light & Wonder game may look bright and innocent on the outside with its whimsical fairytale theme, but underneath its colourful exterior is a big, bad wolf waiting to yoink your cash. 

If you've frequented land-based casinos or your local pub, you might have already seen Huff n' Even More Puff in action. 

If not, it's the second instalment in the Huff slot series, themed around the nursery rhyme about the three little pigs.

It's marked as a medium volatility, but getting into features like the Wheel Feature, Mega Hat Feature, Buzz Saw Feature, or Mansion Feature is a lot harder than you might think, and may require you to sink in lots of money before you hit the bonus. 

With a max win potential of 7,500x stake, you might need to do a lot of extra huffin' and puffin' to blow this house down and beat the game.

4. Royal Potato 2

Print Studios has built up their brand with interesting, out-of-the-box slot themes.

So, when we saw a giant King Edward spud crowned in all its starchy glory, we were hungry to dive in and try Royal Potato 2 for ourselves. 

The team have gone for a “change nothing, upgrade everything” ethos with this sequel, staying faithful to the original without changing the recipe too much. 

This is clearly the case with its highly volatile maths model (ranked 5/5), which means you never quite know if you're going to land a bumper crop or land face-first in the compost bin.

Bonus features include SuperSpinners, the Royal Levy Feature, and the Potato Sack, all working together to potentially produce the maximum win of 40,000x stake. Hitting this, though, is quite the mission as it's locked behind chain-reaction upgrades.

5. Mental II

Are you surprised to see another Nolimit City title on here? You shouldn't be.

Mental II is another smash-hit release from the team, ranked at an insane volatility with a harmony of horror and excitement.

And they do say that insanity is doing the same thing over and over again, expecting a different outcome…

Still, Mental II holds onto the roots of its success from the original, including features like Dead Patients, xNudge Wilds, xHole, xSplit, xWays, and three progressive bonus rounds, where each one will send players on an emotional rollercoaster.

For those feeling particularly brave, the God Mode feature is present with its all-or-nothing approach.

The potential to turn the 6,666x bet cost into the massive 99,999x max win may prove enticing to any volatility seekers out there… and potentially leave them rocking back and forth in the corner of a padded cell.

6. Jammin' Jars

To round off this list, we've got Jammin' Jars by Push Gaming. 

While fruit, groovy soundtracks, and colourful jam jars might not seem intimidating, this is actually one of the most deceptively volatile slots on the market, alongside its sequel: Jammin' Jars 2. 

It features cascading wins, sticky Jam Jar Wilds, and a Rainbow feature that introduces giant fruit symbols onto the grid.

The Free Spins mode offers unlimited multiplier growth to boost win potential, with a max win of 20,000x possible, although there is no way of retriggering these, with these six free spins presenting your only shot to accumulate multiplier value. 

The 96.83% RTP exceeds industry benchmarks for high volatility slots, which balances the risk profile appropriately and suits players who are happy to weather the variance storm for a shot at winning big money.
