CasinoWizard’s Top 10 High Variance Slots For UK
Sami Kurvinen 
High-variance online slots have risen in popularity over the past ten years. We guess that 8 out of 10 new online slots are high-volatility slots.
They attract a particular type of gambler, willing to take more risks in return for a chance to win massive amounts of money.
High variance slots are growing increasingly popular daily, not just because of the immense win potential.
This slot type is very suitable for slots streamers on YouTube and Twitch.
Big wins, exciting bonus features, and, in most cases, the option to buy the bonus feature make for superb entertainment. However, UK players are not allowed to buy bonus features.
Slot providers such as Play’n GO, Quickspin, Push Gaming, Hacksaw Gaming, Netent, Relax Gaming, and Nolimit City have focused on releasing more and more high-variance slots.
Best UK Online Casinos for High Variance Slots
If you want to try your luck at high-variance slots, here are five great online casinos for UK players.
What are high variance slots?
High-variance slots pay out fewer wins than low or medium-variance slots, but prizes are much higher when they do pay.
The hit frequency is lower, but the potential is a lot bigger.
A high variance slot can pay far more significant amounts than a low or medium variance slot.
Low or medium variance slots might offer players top awards between 250x – 1,000x the total bet.
On the other side of the spectrum are high-variance slots.
They offer players the chance to win substantially higher amounts. Wins of 5,000x, 20,000x, or over 100,000 x the stake are possible.
There is even an online slot that can award players a top win of 500,000 times the total bet: Tombstone Slaughter by Nolimit City.
Bigger risks, higher rewards.
Why do players like high-variance slots?
Let’s be honest: nothing beats the feeling of having a bonus round on a high variance slot where everything comes together,
That feeling where you sense something big is about to go down, then it happens.
High variance versus a high return to player
Contrary to popular belief, high variance differs from a high return to player (RTP).
The return to player represents how much the slot machine will pay back to the player, calculated over billions of spins.
An RTP of 96% means that, on average, out of every £100 put into the machine, £96 will be paid back to the player.
Whether you prefer low-variance or high-variance slots, CasinoWizards recommends always playing slots with a high RTP, which can be found at online casinos with high payouts.

San Quentin xWays is one of Nolimit City’s best slots and took the world by storm when it was released in 2020.
The number of features is near endless and may take some getting used to, but it never deters from the super entertaining theme and gameplay.
Earn free spins with Jumping Wilds, Stacked Wilds, xWays, and premium symbols.
The maximum win is as brutal as day-to-day life in the world’s most feared prison and comes in at 150,000 x the total stake.
Free spins can be triggered in the base game or, jurisdiction permitting, by buying the bonus round.
There are two RTP configurations: 94,11% and 96,03%.
Make sure you play the high rtp version of San Quentin xWays to get the best possible odds at winning big.
8. Top Dawg$ – Relax Gaming (RTP 96.10%)
Maximum win: 25,014 x the stake
Release date: June 2, 2021
Top Dawg$ is a fantastic little high-variance slot with a cartoonish hip-hop theme. It stars a gang of neighbourhood canines who are as cool as they get.
The free spins bonus is where the magic happens.
You aim to land as many wilds and bonus scatters during the bonus round as possible; wilds come with progressive multipliers up to x7, triggered by the scatters.
Every scatter also awards an extra spin, leading to one big epic win after another if all goes to plan.
The maximum win is just over 25,000 times the stake, and the Return to Player is fixed at 96.10%.
7. Starburst xxxTreme – Netent (RTP 96.26% – 96.45%)
Maximum win: 200.000x the stake
Release Date: July 15, 2021
Starburst xxxTreme is the natural evolution from the classic low-variance Starburst slot into a high-variance slot.
The gameplay and graphics of the original have been untouched for the most part.
There are still stacked wilds, 10 paylines that payout from both ways and free respins as long as new stacked wilds appear.
New are the wild multipliers (up to x150) and the option to buy super spins (xxxTreme Spins), guaranteeing one or two stacked wilds for 10x or 95 x the bet. The max win on Starburst xxxTreme is an impressive 200,000 times the bet.
The theoretical Return to Player is 96,26% during the base game and rises to 96,45% when you activate the xxxTreme Spins.
6. Cazino Zeppelin Reloaded– Yggdrasil (RTP 96%)
Maximum win: 102,838 x the stake
Release Date: January 27, 2022
Some have described Yggdrasil’s Cazino Zeppelin Reloaded as a Dead or Alive 2 clone with a steampunk theme, but to us, that is not giving this superb slot enough credit.
This visually stunning, 20-payline, high variance slot offers players multiple Bonus Buy options, free spins with sticky wilds, progressive multipliers, and a Golden Bet option.
The maximum win is equally impressive, clocking in at nearly 103,000 times the total bet.
5. Gonzo’s Quest Megaways– Red Tiger (RTP 90.71% – 95.77%)
Maximum win: 21,000 x the stake
Release Date: 23 July, 2020
One of our most-loved high-variance slots is Gonzo’s Quest Megaways by Red Tiger.
It is the Megaways version of Netent’s classic Gonzo’s Quest slot and comes packed with features, such as sticky wilds, a powerful Earthquake Feature with all low-paying symbols removed, and a free spins bonus. The max win is nothing to sneeze at: 21,000 times the bet.
Every winning tumble increases the multiplier during the free spins, reaching x15.
Gonzo’s Quest Megaways is offered at five Return To Player configurations: 95.77%, 94.66%, 93.01%, 92.71%, and 90.71%.
4. Dead or Alive 2 – Netent (RTP 96.80%)
Maximum win: 111,111 x the stake
Release date: 23 April 2019
NetEnt managed to pull off the impossible: they released a better version of the classic high-variance slot Dead or Alive.
Dead or Alive 2 is bigger, better-looking, and offers players three free spins bonus options, including a classic mode option. A Feature Buy version also exists (not available in the UK), offering players a guaranteed bonus trigger for the price of 66 times the stake.
The High Noon Saloon bonus is the one you want to choose, sporting free spins with progressive sticky wild multipliers and a maximum win of 111,111 times the stake.
The odds of landing the maximum win are 1 in 142 million spins.
Landing five bonus scatters awards you an extra prize of 2,500 x the stake.
3. Money Train 2 – Relax Gaming (RTP 96.4% – 98.0%)
Maximum win: 50,000 x the stake
Release Date: September 2, 2020
Some slots are real game-changers, forever sculpting the online slots landscape with unique and innovative bonus features and gameplay.
The kind of slot that sets a new standard.
The Wild West-themed Money Train 2, created by Relax Gaming, is such an online slot.
While the bland, 40 payline base game seems an afterthought, the bonus game is a high variance slots players’ dream.
During the bonus feature, you collect cash prizes, collectors, payers, multipliers, and even necromancers while you try to keep the bonus round alive as long as possible.
The maximum win is capped at 50,000 the bet, and CasinoWizard has seen plenty of evidence on YouTube where players reach wins that high.
2. Book of Dead – Play’ n Go (RTP 84.18% – 96.21%)
Maximum win: 5,000 x the stake
Release date: 14 January 2016
While Play’n GO’s Book of Dead slot has a modest maximum win of 5,000 x the stake, it is the most played high variance slot ever.
The ten win line, Egyptian-themed slot was heavily inspired by the popular Novomatic slot Book of Ra.
Land three or more scattered Book symbols to trigger the free spins bonus round, with an expanding bonus symbol.
A full screen of Rich Wilde Explorers is the maximum win, awarding 5,000 times the bet.
Book of Dead comes in five RTP versions: 96.21%, 94.25%, 91.25%, 87.25%, and 84.18%.
The difference between the best-paying and the worst-paying Book of Dead version is considerable: 12%.
Before playing this slot, make sure you play Book of Dead with the highest Return to Player.
1. Tombstone RIP – Nolimit City (94.08% – 96.08%)
Maximum win: 300,000 times the stake
Release Date: January 11, 2022
Tombstone RIP is on our top 10 best high variance slots list and coveted first spot.
Of course, it is.
Nolimit City is always looking for new angles, extreme themes, and innovative gameplay to ensure their slots are kickass to the max.

This maximum win occurs once in 130 million rounds, a superb max win probability for such a high max win.
There are two RTP configurations: 94.08% and 96.08%.
Are High-Variance slots extra risky for players?
The short answer is yes. The rewards can be great with high-variance slots, but they can come at a price. Playing high-variance slots is extremely risky, and your funds can drain fast if you are on the wrong side of the variance.
High-variance slots are also risky for online casinos, as players might walk away with massive wins. This is one of the reasons you never find free spin bonuses on these games.
Playing responsibly is always the way in an online casino, especially when playing high-variance slots.
