Top 10 Best High Variance Online Slots
High variance online slots attract a particular type of gambler – one that is willing to take more significant risks for a chance to win massive amounts of money.
High variance slots are growing more and more popular every day, offering players excitement, big thrills and even bigger jackpots.
It comes as no surprise that new high variance slots are released all the time: the demand is there, and where there is demand, there is a market. Every self-respecting casino software provider offers at least one high variance slot in their game portfolio, and most have a whole range of High Variance Slots.
A high variance slot has the potential to pay out far greater amounts than a low or medium variance slot. A low or medium variance slot might offer players a top award of 250x – 500x the total bet. High variance slots will offer players the chance to win 3,000x, 5,000x or even 10,000x their initial stake.
And big wins are exactly what fans of high variance slots are looking for – no messing about with bonus rounds that pay out a 100x the stake at the most.

All of these online slots are very popular among high-risk players and offer a thrilling, exhilarating experience with big win potential. You can play these high variance slots at any of our top 10 online casinos or top slot sites in the UK.
1. Book of Dead – Play ‘n Go
Return to player: 96.76%
The Book of Dead slot by Play ‘n Go was released in 2016 and has quickly become the most played high variance slot. This ten win line, Egyptian themed slot was heavily inspired by the popular Novomatic slot Book of Ra. It offers players an exciting free spins bonus with scatters, wilds and expanding symbols.
Before the free spins bonus starts, one random symbol is awarded – this is your special symbol. During the free spins, this special symbol becomes a scatter symbol and expands across the whole reel. The maximum payout during the bonus round is an incredible 50.000 x your bet per win line!
2. Dead or Alive – Netent
Return to player: 96.80%
Dead or Alive is one of the most infamous high variance slots and was created by Netent. The game is based on a bit of a bland Wild West theme and offers nine win lines, wilds and a free spins bonus. Now, this might not sound too exciting, but Dead or Alive comes to life during the free spins bonus round.
Whenever three or more scatters appear during the base game, the player is awarded 12 free spins that come with a 2x multiplier. Every wild symbol that appears on the reels during the free games becomes sticky.
If you manage to get at least one wild symbol on all five reels, you will be awarded 5 extra free spins. Every active full wild line is good for 1,500 x your line bet. Trigger the bonus with 5 scatters and you are looking at 2,500 times your total stake. Dead or Alive can pay out huge wins: bonus rounds wins of 10.000x or even 12.000x the total stake have been reported.
3. Immortal Romance – Microgaming
Return to player: 96.86%
When Microgaming first released their Twilight-inspired and epic Immortal Romance slot in 2011, players loved the beautiful graphics, amazing soundtrack and exciting bonus features. This 243 ways-to-win high variance slot was an instant hit and remains one of the most played slots to this day.
One of the bonus features, the Wild Desire feature, can turn all five reels wild, leading to a maximum possible payout of 3,645,000 coins when playing the maximum bet. The other bonus features can bring home the bacon as well, making Immortal Romance a delight to play.
4. Jurassic Park – Microgaming
Return to player: 96.67%
The Jurassic Park movie franchise is one of the most successful ever. Who hasn't watched those jaw-dropping, lifelike dinosaurs on the big screen? It was only a matter of time before a software developer would snatch up the rights to make a Jurassic Park slot machine, complete with roaring Tyrannosaurus Rex and Velociraptors?
Microgaming launched the high variance slot version of Jurassic Park in 2014 and wow, what a great slot it has proven to be.
It offers 243 way to win, stacked symbols, a random T-Rex feature, extra wilds and multipliers that go up to 6x. Jurassic Park is filled to the brim with exciting bonus features and offers players a high variance, beautifully designed experience, complete with real movie footage.
5. Raging Rhino – WMS
Return to player: 95.91%
Raging Rhino is the first WMS slot on this top 10 of high variance online slots and is, without a doubt, one of the most played WMS slots. Raging Rhino is found in casinos on the Las Vegas Strip and Atlantic City as well as in online casinos. To say Raging Rhino is cool slot may be somewhat of an understatement. It offers players a thrilling experience with 6 reels, 4 rows and 4,096 ways to win. To make things even more interesting, there are stacked symbols, wilds and multipliers up to 81x (during the bonus round).
Three or more scattered diamonds will trigger the free spins bonus round and award up to 50 initial free spins. During the free spins, the Tree symbol plays a critical role. It acts as both the wild symbol and a 2x or 3x multiplier. If you manage to catch several wilds/multipliers and a high paying stacked symbol, your winnings can go through the roof.
Two scattered diamonds retrigger the bonus and award 5 extra free spins. As with many other WMS slots, Raging Rhino has a Bonus Guarantee feature built in – you are guaranteed a 10x your stake payout with every bonus round that is triggered. The fantastic Raging Rhino slot can be played with a minimum stake of 40p and a maximum bet size of £120 per spin.
6. The Wish Master – NetEnt
Return to player: 96.60%
The Wish Master is a unique and delightful high variance slot by Netent. It offers some unique features, including unlimited booster spins, where up to three bonus boosters may apply for every spin. These boosters can contain a variety of extra features, such as random wilds, extra wilds, expanding wilds, multipliers and more.
Every retrigger awards 6 extra free spins, with features stacked on top of each other. With the right combination (for example random wilds, expanding wilds and 3x multiplier), it is possible to catch some incredibly big wins.
This popular slot revolves around a “Genie in the Bottle” theme, where the Genie in question awards the player with free spins and extra features. There are 20 win lines, 5 reels and 3 rows. The minimum bet is 20p per spin, but to hit the jackpot, you should be betting at least 60p. The maximum bet is £120 per spin, with a maximum jackpot of no less than 900,000 coins.
The Wish Master is capable of paying out massive amounts of money. Be advised that you do need a lot of luck and patience with this slot; it can be very frustrating just the same. Make sure your starting balance is high enough to get you through those inevitable long series of dead spins.
7. Montezuma – WMS
Return to player: 95.86%
Visually nothing short of gorgeous, the Aztec-themed Montezuma online slot is another big winner from WMS. This 30 win line, 5 reel, high variance slot has got it all: the looks, the wow factor and ever-present potential for big wins. Huge wins.
Three or more scatters trigger the free spins bonus for up to 25 free spins. During every free spin, you are given a multiplier up to 10x. But that is not what makes Montezuma the great slot that it is. It offers players a unique way to retrigger free spins – you only need two scatters to win up to 25 more free spins. And what's even better: you keep the multiplier for the duration of those extra free spins and any further free spins that you retrigger while on that multiplier.
It is possible to amass tens, or even hundreds of free spins at a 3x, 5x or even 10x multiplier. If that doesn't get your adrenaline level up, we don't know what will.
8. Cazino Zeppelin – Yggdrasil
Return to player: 96.00%
Some have described Cazino Zeppelin by Yggdrasil as a Dead or Alive clone, but that is not enough credit for this visually stunning high variance slot with very smooth gameplay.
The theme is Victorian Steam Punk, there are 20 win lines (a big difference compared to that “other one”), and it is possible to win up to 20 free spins. Any wild that appears on the screen as the bonus is triggered and during the free spins, becomes a sticky wild for the whole duration of the free spins. Get a wild symbol on every reel, and you will win 5 more free spins – even bigger wins.
Cazino Zeppelin is a beautiful, fast-paced slot that is our go-to slot whenever we want to play a high variance slot that is pleasing to the eye as well as capable of providing the big wins. Bonus payouts of 3,000x up to 5,000x occur frequently.
9. 300 Shields – Nextgen
Return to player: 95.3%
300 Shields by Nextgen is based on the epic battle between 300 well-trained Spartan soldiers and a huge Persian army. This slot offers thrill-seeking slot players an unusual premise: a multiplier of 300x. This is the highest multiplier we have ever seen on a slot machine. It is reached by collecting shields in the bonus round – find enough of them, and you will win free spins with that enormous 300x multiplier (on wins with a wild symbol).
- Collect 2 to 5 shields during the free spins for 5 extra free spins and a 5x multiplier.
- Collect 6 to 11 shields during the free spins for 5 extra free spins with all Warrior (wild) wins subject to a 25x multiplier.
- Collect 12 or more shields for 5 extra free spins with all warrior wins subject to a staggering 300x multiplier.
Getting the 300x multiplier does not happen every day but is most certainly can be done. Make it to the end, and epic wins will follow.
10. Gonzo’s Quest – Netent
Return to player: 96,00%
Gonzo's Quest by Netent might be Netent's second most played slot, following Starburst. Where Starburst is a typical low variance slot, Gonzo's Quest is anything but low variance.
Gonzo's Quest offers players appealing graphics, avalanche symbols, a free spins bonus and multipliers up to 15x. And let's not forget Gonzo's antics as he cheers you, even treating you to the occasional moonwalk. Up to 20 free spins can be won, and they can also be retriggered.
Gonzo's Quest has become such a popular slot that scores of clones have been developed – but none have the charm and magic that Gonzo's Quest has.
High variance versus a high return to player
High variance is not the same as a high return to player (RTP). The return to player is a percentage that depicts how much the slot machine will pay back to the player, calculated on average over an extended period. The variance of a slot is more focused on the short-term and is a good indicator of the “risk”, that is involved with that slot machine. To put it simply, a low variance slot machine is a “low risk” slot machine, which offers lots of small wins and a medium win, now and then.
A high variance slot is a “high risk” machine. It will not pay out a lot of winning combinations but will award a massive win from time to time.
Whether you prefer low variance or high variance slots, it is also recommended always to play slots with a high RTP. If the RTP of a slot is 97%, this means that out of every £100 that is put into the machine, £97 will be paid back to the player on average over an extended period.
Why do players like to play high variance slots?
Some casino players have a strong preference for high variance slots. These players know and accept the increased risk that high variance slots bring, in exchange for a genuine chance of hitting a monster payout. They know that they might not win most of the time, but they will hit a mega jackpot sometimes. It is for this reason why Megaways slots are so popular in 2021. Most online slots with the Megaways engine are high in variance and offer exciting gameplay and rewards.
