HIGH VARIANCE SLOTS – THE 15 BEST HIGH VOLATILITY SLOT GAMES AND WHERE TO PLAY THEM

Last Updated: September 10, 2025

Written by Iain Fenton

Thrill seekers and risk takers – you have the opportunity to try your luck on the highest volatility slot games. Slot machines come in three variances (aka volatility): low, medium and high volatility. So, what are high variance slots exactly? Slots with high volatility/variance give the opportunity for big potential wins at the expense of less regular payouts.

The table below showcases the 15 best high volatility slots. Our list is based on playability, volatility level expected max payout and RTP percentage.

If you are short on time, our top pick is MeJUICEa by Thunderkick, which we agree is the best high variance slot available right now and is playable at Casumo Casino.

BEST HIGH VOLATILITY SLOTS IN 2025

After researching max payouts, RTPs and general playability, we have compiled a list of what we believe are the 15 most volatile online slots that you can play at online casinos. However, our editor in chief Jean Prince has chosen his editors pick for you below:

EDITORS PICK: 80S POP (RTP: 96%) BY AVATARUX

AvatarUX are a somewhat unknown slot developer, but they have some truly special and unique slots, with their best high variance slot being 80s Pop. For each win you achieve in the base game, winning symbols will ‘pop’ to be replaced by two new symbol places. The more wins you hit in a row, the more rows you will see growing on the grid! Expand the rows to six symbols tall and you will trigger the bonus game.

During our playthrough of 80s Pop, we hit a 500x+ win during the bonus game which you can view on the official SlotsHawk YouTube channel. There is also a global multiplier which increases the chances of huge wins during the bonus game. You can also win up to 20,000x during the base game.

Features:

• Free spins
• Bonus game
• Respins
• Expanding reels and rows
• Multipliers
• Popwins
• Bonus wheel

1. MEJUICEA (RTP:94.18%) BY THUNDERKICK

MeJUICEa is one of the best slots we have ever played at SlotsHawk. Why, you may ask? The Crush feature is absolutely brilliant, as well as looking fantastic, every time it happens, you will likely see the Global Multiplier increase which means that multiple wins can spiral into bigger and bigger payouts.

Although big payouts in the base game are completely possible, it is the bonus game where the level goes up another notch. During the MeJUICEa free spins, the Global Multiplier is persistent, so it will not reset after each spin. Our slots analyst Stephen, who tests all f the slots here at SlotsHawk.com, implores you to try this high variance slot out, we are sure that you will love it.

Features:

• Free spins
• Bonus game
• Respins
• Cluster pays
• Scatter symbols
• Wild symbols
• Multipliers
• Global multiplier
• Charge meter
• Crush feature
• Bonus boost
• Bonus boost plus
• Juice boost

2. FIRE IN THE HOLE 3 (RTP: 94.08%) BY NOLIMIT CITY

Fire in the Hole 3 is one of the top recent slot games with high volatility released by the Kings of volatility, NoLimit City. This one is a little more straightforward in comparison with some other NoLimit slots, so it’s a good choice for those who are new sot slot machines. With that being said, it is still packed with some top-quality and unique features including the xHole and the exceptional NoLimit Boosters which we recommend using in order to trigger the Lucky Wagon spins.

When our slots analyst Stephen played Fire in the Hole 3 for real money, he managed to trigger several bonus games, one of which triggered a 372x win. This is currently our favourite NoLimit slot game with high volatility and with a maximum payout of 70,000x, it is also one of the best payout slot games around. You can play Fire in the Hole 3 at most UK casinos including Casumo Casino.

Features:

• Free spins
• Bonus game
• Scatter symbols
• Wild symbols
• Exploding reels
• XSplit
• Xbomb wild
• NoLimit boosters

3. KILL EM ALL (RTP: 96.06%) BY NOLIMIT CITY

Arguably the most unique online slot machine ever created, the excitement as well as the volatility is insanely high in Kill Em All from mega volatility slots experts, NoLimit City. If any developer was going to create one of the most fun slots of the year from a one reel and three row slot it was NoLimit City. Now make no mistake about it, the volatility here is very high which can make Kill Em All quite a frustrating game during the phases when you hit no wins. In addition, this slot revolves around defeating monsters and the more you defeat in a single round, the higher your rewards will be. However, as soon as you fail to defeat a monster, you will be returned to the beginning.

The more wins you hit, the more rewards and special features you will unlock. Kill Em All is an extremely moreish slot and is the most volatile slot game in the world right now. We did not want to stop playing, however we did lose over £70 during our 40 minute gameplay session so you should ensure that you have a large enough bankroll when you do play.

Features:

• Free spins
• Bonus game
• Sticky multipliers
• Respins
• Scatter symbols
• Super scatter symbols
• xNoLimit Booster
• xGod Mode

Play at: Casumo Casino

4. BRUTE FORCE: ALIEN ONSLAUGHT (RTP: 96.01%) BY NOLIMIT CITY

The newest high variance slot in this guide, Brute Force: Alien Onslaught is the successor the the original Brute Force and this one comes with more payouts, more free spins and more xNudge Wilds! The xBoost in particular is a brialliant addition as it ensures that activating any of the free spins games is eight times more likely.

When the SlotsHawk casino team played this slot for real money, we triggered two wins of over 1,000x! The Blu Genesis bonus game is especially a good one thanks to the sticky xNudge Wilds. The base game does not offer a great deal of payouts as like most NoLimit City slots, it is the bonus games where the fun happens.

Features:

• Free spins
• Bonus game
• xNudge wilds
• Multipliers
• Sticky symbols
• xBoost
• Scatter symbols

Play at: All British Casino

5. TANKED (RTP: 96.04%) BY NOLIMIT CITY

Tanked reminds me of the classic ‘Worms’ video game series, which is exceptional praise from my point of view. This is one of the most immersive and technically excellent online slots on the market. The base game is a lot of fun which is lucky because the free spins here are difficult to trigger (1 in 249 spin on average). It is in the Carnage Spins and Mayhem Spins bonuses where the huge wins are available though.

Utilising the xBet feature will increase your chances of triggering the bonus by four though, so we do recommend that at the cost of three times your base bet. The minimum bet is 20p per spin, so using the xBet will make your bets 60p per spin. Of course, Tanked has high volatility considering it is on our list of the top 15 high volatility slot games, but because its from NoLimit City, it really is at the top end of the volatility spectrum.

Full List of Slot Features:

• Free spins
• xLoot
• Tank boosters
• xNudge
• xSpilt
• Gird expansion
• xBet
• xBomb
• Barrel bomb
• Multipliers
• Scatter symbols
• Wild symbols

Play at: Casumo Casino

6. OODLES OF NODDLES (RTP: 96.58%) BY PRAGMATIC PLAY

A slot which hasn’t quite had the publicity that we perhaps expected it might have had, Oodles of Noodles is nonetheless one of Pragmatic Plays best releases for along time with its high RTP of 96.58% and maximum multiplier of 5,100x. Please be aware that this slot has an adjustable RTP, so it is imperative that you play it at an online casino which will allow you to play on its optimal RTP. For example, if you play Oodles of Noodles at Pub Casino, you will be able to play with the max RTP. On the other hand, if you play at Dream Vegas, the RTP will be as low as 94.55%.

The bonus game is the highlight here as the revolving Sushi reel at the bottom of the game will become active. There are also repsins during the bonus game. The base game is not the greatest, but all in all, Oodles of Noodles is an excellent slot machine to try out if you haven’t already.

Full List of Slot Features:

• Free spins
• Scatter symbols
• Respins
• Instant wins

Play at: Voodoo Dreams Casino

7. SKATE OR DIE (RTP: 96.03%) BY NOLIMIT CITY

Millennials rejoice, Skate or Die takes much of its inspiration from the 90s era of skateboarding and kick-ass music. Packed full of features which includes three different free spins games and a special ‘crasher‘ game which allows you to win the maximum 30,000 payout, Skate or Die is a truly unique high variance slot.

One important factor to know though is that the likelihood of triggering the max payout is low – one in 11.2 million spins to be precise! With that being said, there is so much happening in this video slot that you won’t be too focused on trying to trigger the crasher game.

Full List of Slot Features:

• Free spins
• Bonus games
• Crasher game
• Multipliers
• Extra Sauce row
• xZone wild
• xNudge wild
• xNudge Wild Supreme
• Scatter symbols

Play at: Casumo Casino

8. PIGGY RICHES 2 MEGAWAYS (RTP: 95.71%) BY RED TIGER

A huge improvement on the first slot machine in the series, this is a real gem of a slot and is fairly widely available at UK online casinos. The volatility here is even higher than the first Piggy Riches too, but with that being said, we found wins to be a fairly common occurrence. In fact, our team believe Piggy Riches 2 Megaways to be one of the best slot games currently on the market due to its simplicity mixed with remarkable features, the best of which being the Hold and repsins features.

Like most slot machines, the bonus game is where the biggest payouts are won. It is possible to activate more rows in the bonus too which increases your chances of bigger wins even more. When we tested this game, we triggered 351x across our free spins.

Full List of Slot Features:

• Bonus game
• Free spins
• Big wheel spins
• Multipliers
• Hold and respins
• Cash symbols
• Multipliers
• Wild symbols
• Scatter symbols

9. PIRATES PUB (RTP: 96.03%) BY PRAGMATIC PLAY

Pirates Pub is one of our favourite new high volatility slot releases due to its excellent graphics and modern mechanisms and features. Themed around pirates and pubs, Pragmatic Play have done a fantastic job when designing this slot.

Played on five reels and three rows with 9 paylines, Pirates Pub has the potential to become a classic slot game. Features include Sticky wild symbols, multipliers, repsins and wild reels. Play Pirates Pub and you will have the opportunity to trigger multipliers of up to 100x. Meanwhile, the maximum potential payout in Pirates Pub is set at 5,000x your bet.

Play at: ZetBet Casino

10. RAZOR WAYS (RTP: 96.36%) BY PUSH GAMING

Razor Ways is certainly one of Push Gaming’s best slot releases so far this year. They have done an excellent job of improving and revitalizing the original slots in the ‘Razor’ series. So, what makes Razor Ways so special in comparison with other online slot games, I hear you ask? The expanding reels certainly help to ensure that the base game is exciting. The more wins you manage to trigger, the more reels you get to play on which will create more and larger wins. Winning symbols explode too, so there is always the possibility of unlimited wins.

The bonus game is where the biggest wins occur due to the level up meter and the glowing mystery symbols which help to fill the meter up, resulting in larger multipliers. The only real downside is the low maximum bet per spin of just £4.50. The maximum payout is 25,000x your bet and Razor Ways utilises the Scatter Pays mechanic.

Full List of Slot Features:

• Free spins
• Bonus game
• Expanding rows
• Expanding wild symbols
• Razor Reveal
• Instant wins
• Mystery symbols
• Glowing mystery symbols
• Multiplier level meter
• Expanding rows
• Cascades
• Push bet

11. MEDUSA MEGAWAYS (RTP: 97.63%) BY NEXTGEN GAMING

Based on the Greek mythological Gorgon monster, Medusa Megaways is a high volatility slot machine from NextGen Gaming. This slot is one of the original and classic Megaways slot games played on six reels. The minimum bet here is £0.25 that you can increase up to £25. It is possible to win 50,000x your total bet on this high variance online slot.

The graphics are cool and the theme is bold. The unique features make this game well worth playing and the massive payout percentage as well as the high RTP means that Medusa Megaways is one of our top recommended slot machines with high variance.

The SlotsHawk team recently tested Gorilla Mayhem at Luckster casino and we can confirm that it can be played by both experienced and beginner slot players. We recommend a low betting strategy.

The layout here is a 5×4 grid with 1,024 paylines. The RTP is 94.50%, which is a little on the lowside and the maximum payout is 5,000x the original wager.

EXPLAINING TYPES OF SLOT VARIANCES

Don’t forget, there are three different types of slot volatility levels. Here’s a quick look at the main differences between low, medium and high. This should paint a clear picture for choosing which type of slot machine is correct for you.

LOW VARIANCE SLOTS

Low variance slots are the opposite of high volatility slot machines. In low variance slot games, the wins come regularly but the payouts are much smaller in comparison to their high variance counterparts.

Low variance slots are best suited to beginner slot players. you can read more about these slots by visiting our low variance slots page.

MEDIUM VARIANCE SLOTS

As you have probably worked out by now, medium variance slots are somewhere in between low and high variance games. These slots produce plenty of low-medium sized wins with a sprinkling of large wins too.

Medium variance slots give the opportunity to win a decent number of times without having to risk too much of your bankroll. However, this is often not enough for those risk taking players who are looking to win big!

HIGH VARIANCE

High variance slots come at the other end of the spectrum, you have to play these slots for a while before you hit a win, but when a win does arrive, the sum is likely to be big. These slots tend to attract high roller slots players and players who like to make large deposits.

THE IMPORTANCE OF SLOT VOLATILITY

If you plan on playing slots for the long-run, it is advantageous to at least be aware of the volatility of the slots you are playing. However, there are other factors which should be considered too.

For example, slots with a higher RTP will payout more in the long run, regardless of the volatility factor. A high RTP mixed with high variance is likely to affect how much you win when playing an online slot.

RTP will effect how much you will win over a long period of time. For example, a slot with 97% RTP will pay £97 for every £100 put into the slot. This percentage is theoretical and is determined after several millions of spins. In reality, there is a lot of luck involved. However, it makes sense to play volatile slots which also come with a high RTP.

IS THERE A DIFFERENCE BETWEEN VARIANCE AND VOLATILITY

There are no real differences between the terms variance and volatility. It is safe to assume that a high variance slot is the same as a high volatility slot.

ADVANTAGES AND DISADVANTAGES OF THE MOST VOLATILE ONLINE SLOT GAMES

Like all aspects of life, high variance slots come with both advantages and disadvantages.

Advantages of high variance slot games:

• More potential for high payouts
• Can be more rewarding in the long run
• Many of the newest slots have high variance

Disadvantages of high variance slot games:

• Higher risk in comparison with lower variance slots
• Wins are sometimes less regular

There are pros and cons of all online casino games, the most important factor to consider is how much fun you are having. However, when playing high volatility slots, you need to take your bankroll more into consideration.

WHERE TO PLAY HIGH VARIANCE SLOT GAMES

Any online casino which has its own library of slot games will likely stock a variety of slots with high variance/volatility. However, there are hundreds of such casinos to choose from in the UK alone.

Our slots analyst has picked our his choice of the casinos which he regards as the best ones for extreme volatility slots players.

• All British Casino – An online slot site dedicated to UK players only, All British Casino has a games library of hundreds of the highest volatility slots. In addition, everyone who plays at All British Casino will receive 10% cashback on losses at the end of every month.
