Compared to low volatility slots, high volatility ones come with a high-risk gambling experience. While they can land you some huge winnings, they can also eat up your bankroll within seconds.

List of the High Volatility Slot Machines

Below, we’ve put together a list of high volatility slot machines that promise amazing gameplay:

  1. Book of Dead (Play’n Go) – 96.21% RTP rate
  2. Gates of Olympus (Pragmatic Play) – 96.50% RTP rate
  3. Bigger Bass Bonanza (Pragmatic Play) – 96.71% RTP rate
  4. Big Bad Wolf Megaways (Quickspin) – 90, 94 or 96% RTP rates depending on the math model
  5. Legion X (Nolimit City) – 96.04% RTP rate
  6. Full Moon Fortunes (Playtech) – 94.01%

Book of Dead (Play’n Go)

The Book of Dead Slot

Book of Dead is one of the few Egyptian-themed slots that needs no introduction. Developed by Play’n Go, this slot stands out as one of the leading choices for casino bonuses and various promotional offers. The main bonus feature of this game is the free spins. The slot is a 5-reel slot with a 96.21% RTP, which is also above average. Book of Dead offers a maximum payout multiplier of up to 5,000 times your bet.

Gates of Olympus (Pragmatic Play)

The Gates of Olympus Slot

The Gates of Olympus slot is an ancient Greek slot with captivating visuals. It is a high-variance slot established in 2021 by Pragmatic Play with a maximum payout range of 5,000x your bet. This slot also features an RTP percentage of 96.50%. Since the game supports a maximum bet of £125 and a max payout of 5,000x, the highest payout on this game can reach as high as £630,000.

But, as expected, landing a significant winning combo on these high bets can be challenging.

Bigger Bass Bonanza (Pragmatic Play)

Bigger Bass Bonanza Slot

Bigger Bass Bonanza is a popular game in online casinos, primarily due to its unique fishing theme and huge payout potential. This slot by Pragmatic Play is a popular sequel to the original Big Bass Bonanza but with a higher payout potential, giving you up to 4,000x on your bet.

With an RTP hitting 96.71%, the slot gives you good value for your money and a chance of bagging a massive payout if you’re lucky. Also, other in-game features like the tumble feature, scatter pays, free spins and multiplier symbols enhance the gaming experience significantly.

Big Bad Wolf Megaways (Quickspin)

Quickspin released three models of the Big Bad Wolf Megaways, which featured RTP rates of 90%, 94% and 96%, respectively. While the slot may not be mind-blowing, it features stunning graphics and exceptional gameplay animations. But, the key highlight of this slot lies in its maximum payout capabilities. Big Bad Wolf Megaways pays as high as 30540x your bet, with max bets reaching up to £100 per spin.

Legion X (Nolimit City)

Legion X offers one of the biggest multipliers on our list, reaching up to as high as 31,000x your bet. It is an ancient Roman battleground with 5 reels and several bonus features: free spins and jackpots. With the maximum payout of up to £100, Legion X can pay a single lucky player as high as £3,100,000, but landing this prize or anything close to is quite difficult, as this high volatility slot rarely triggers a good winning hand during active gameplay.

Full Moon Fortunes (Playtech)

Full Moon Fortunes is a 5-reel slot with 20 fixed paylines and several bonus features that can unlock different payouts. Generally, the gameplay of this slot is similar to that of other slots like Blood Suckers II, but the difference is in their payouts. Full Moon Fortunes pays you as high as 12,500x your bet, which is high considering the max bet of £100.

Other High Volatility Slots

The slots outlined above are undoubtedly some of the best high volatility slots, but there are many others out there. Below are some other popular high volatility slots you’ll find in UK casinos:

  • Crystal Sun Slot (Play’n Go)
  • Wanted Dead or Wild (Hacksaw Gaming)
  • Dead of Alive 2 (NetEnt)

How Slot Volatility Works

The volatility of a slot represents the potential risk and frequency of triggering winning results. It is a measuring percentage that determines how often your winnings occur and how much you can expect to win from a slot.

💡 If the volatility of a slot is high, you have a higher risk of losing your bets, as slots with high volatility payout less often.

At the same time, slot machines with lower volatility tend to pay more often but less in value than high volatility slots. Nevertheless, it’s essential to understand that volatility isn’t a rigid framework, as there are rare cases where even low to medium volatility slots can result in significant payouts.

How Slot Volatility Is Calculated

How Slot Volatility Is CalculatedIt is tricky to correctly calculate the volatility of a slot, as that is the software providers’ job. Slot volatility generally revolves around analysing the payout frequency and the size of wins in a game, but it is tricky to correctly calculate it on your own.

The exact calculation of slot volatility is not typically disclosed by game developers, but they usually display this type of information on their websites.

In this section, we’ll outline 3 main ways that can help you understand whether a slot is a high or a low volatility one:

  1. Searching online
  2. Reading the paytable
  3. Observing maximum wins

Searching Online

The easiest way to quickly determine the volatility of a casino slot is to search for it online. Just type the name of the slot and the keyword ‘volatility’. This search will reveal a result page with relevant information. Now, it’s crucial to ensure that you rely solely on information from websites of official game studios, casinos, or trusted review resources such as CasinoSherlock.

Reading The Paytable

Another easy way to detect the volatility level of a slot is to carefully go through the paytable, as well as the game symbols and their payout rates.

🎰 Did you know? Generally, the more chances you have at winning, the less likely you are to bag huge prizes.

A slot with many winning lines would likely be low volatility one.

In most cases, slots with lower number of paylines, around 0-20, belong to the medium to high volatility categories. Whereas those with higher paylines number, reaching 200+, give more chances for players to win, leading to a lower-valued paytable to make up for the frequent payouts.

Observing Maximum Wins

One of the significant signals that can give away the volatility level of a slot is the maximum wins available. Suppose you play a slot offering 100x to 500x multipliers as your full payout possibilities. In that case, you’re most likely playing a low-variance slot. Generally, these slots allow you to record frequent wins but with small payout ranges. You will see bigger payouts ranging from 5000x to even as high as 50000x in high-variance slots.

Most high volatility slots are produced by reputable game studios. Therefore, you can expect excellent optimisation across all devices, regular updates, and good support with online casinos.

Finally, whether you prefer 3×3, 5×3 or even 7×7 grid slots, regular titles or Megaways slots, high volatility slots are available in all forms, shapes and types. Regardless of the slot type you prefer to play, you can always find a high volatility title that matches your needs.

Tips For Playing High Volatility Slots

Tips for Playing High Volatility SlotsSlot results depend solely on RNG systems, meaning that there’s no way to influence the outcome of a spin with certain strategies or tips. However, there are some approaches and best practices that can help manage your gameplay and potentially enhance your overall gaming experience:.

Here are our top 3 tips to make the most of your gaming sessions:

  1. Bet wisely
  2. Do not try to double a win
  3. Utilise free play

Bet Wisely

When playing a slot with high volatility, it’s important to calculate your steps and take your time.

✅ Play within your budget and bet using amounts you can afford to lose.

Since high volatility slots rarely trigger winning combinations, they can easily drain your bets during gaming sessions. As a result, its’ best to split your bets into smaller units to ensure a longer gaming period.

The only case where it makes sense to place huge bets on high volatility slots is when using bonus funds. In this situation, you can use casino bonuses as a shield before utilising your real money deposits.

Do Not Try to Double a Win

A high volatility slot only triggers winning combos once in a while. Even if you’re lucky enough to land a huge payout using less than five spins, you’re better off walking away. If you land one winning hand, there is a higher chance that it won’t reoccur anytime soon. With that in mind, leaving after a significant win is the safest way to go.

When you land a big payout, a part of you may push you to double your wins and keep playing. But, in this scenario, leaving would save you a lot of complications and possible losses.

Utilise Free Play

Almost every slot game features a free-play mode, allowing players to try the game before using real money.

💡 Before playing any high volatility slot, familiarise yourself using its demo edition to understand how the game works and how to use the bonus features available.

Of course, slots are luck-based, so your skills do not really matter. However, a good understanding of any high volatility slot is an advantage, as it can improve your gaming sessions.

Our Verdict on High Volatility Slots

The high maximum winning multipliers and great bonus support of high volatility slots are the two main factors that make them unique and popular among players. However, it’s important to note that these slots tend to have a relatively low frequency of wins.

As a result, they are primarily suitable for high rollers willing to split their bets into numerous smaller units for continuous betting. Due to their nature, it’s never a good idea to risk it all when playing games with high volatility.
