1. Vikings Go Berzerk Reloaded
Released in September 2021, the Vikings Go Berzerk Reloaded slot is a remake of the original 2016 game. With 5 reels and 25 paylines, there are Multiplier Wilds worth up to 8x. The random Ragnarok Spin sees Viking symbols go into Berzerk Mode where the victors transform into wilds.
In the Free Spins feature, you begin with up to 9 free spins with 2 Berzerk Vikings. If Vikings win their battles, they become sticky wilds. Wilds can also upgrade to Multiplier Wilds up to 8x. Lookout for Treasure Chests as these award extra free spins, sticky wilds, more Berzerk Vikings or double multipliers (up to 8x).
With a 96% RTP rate, Vikings Go Berzerk Reloaded is an iconic Yggdrasil Gaming slot game with 25,000 x bet max wins. It offers the highest max win potential of all games in the Vikings series.
2. Cazino Zeppelin Reloaded
Released in January 2022, the Cazino Zeppelin Reloaded slot is the remastered version of one of Yggdrasil Gaming’s first slot games. With 5 reels and 20 paylines, this steampunk-themed game is very high volatility and can be played from 20p a spin.
With Multiplier Wilds up to 5x that can combine, the focus is on the Free Spins feature where you begin with up to 20 free spins. All wilds are sticky and begin with a 1x multiplier. When a new wild lands, the multiplier increases by 1. If you land wilds on all 5 reels, extra free spins will be won.
With a 96% RTP rate, Cazino Zeppelin Reloaded may be a simple game but it comes with 102,838 x bet max wins making the highest of all Yggdrasil Gaming slots. If you want high max win slots, check out my dedicated guide where you’ll find games that offer up to 500,000 x bet max wins:

3. Golden Fish Tank
Released in February 2016, the Golden Fish Tank slot is a 5 reel, 20 payline game that can be played from 20p per spin. This underwater adventure focuses on the Free Spins feature where you begin with up to 10 free spins with 5 feature picks.

4. Hades GigaBlox
Released in October 2020, the Hades GigaBlox slot sees you join the king of the underworld on a 6 reel game with 50 paylines. Using Yggdrasil’s GigaBlox mechanic, symbol blocks from 2x2 up to 6x6 in size will appear.
There is a Hades Wild Hunt feature where Hades jumps onto the reels and fights with high-value monster symbols. If Hades emerges victorious, the defeated monster transforms into a wild symbol (can also apply to blocks on monster symbols). In the Wild Hunt Free Spins feature, you’ll begin with between 5 and 36 free spins. With more free spins to be won, Hades battles monsters for more wilds. Every fight Hades wins fills the Cerberus Multiplier Meter which increases the win multiplier on every free spin up to 10x.
With a 96% RTP rate, Hades GigaBlox comes with 11,129 x bet max wins on every free spin. If you like Greek mythology slots, it’s one of the most popular slot themes so there are plenty of options. Like games featuring Hades? You’ll find him in Playtech’s Age of the Gods, Play ‘n GO’s Rise of Olympus and Pragmatic Play’s Zeus vs Hades – Gods of War. More games can be found in my dedicated guide:

5. Devour the Weak
Released in April 2023, the Devour the Weak slot sees you head to the underworld where you battle dark magic. With 5 reels and 243 ways to win, you can spin away from 10p a spin. In the Dropdown Wins feature, all winning symbols plus low-value symbols are removed from view to allow new, high-value symbols on the reels.
Look out for Hexed symbols being part of a win as they transform into wilds and fill the Free Spins meter. Every win also adds to the Multiplier Meter which can increase up to 666x. In the Free Spins feature, Hexed symbols turn wild on the middle 3 reels and can turn wild on reels 1 and 5 if part of a win. The Multiplier Meter begins at 6x too.
With 10,000 x bet max wins and a 96% RTP rate, Devour the Weak is all about witchcraft. If you like the dark theme, I recommend reading my Halloween slots guide where you’ll find games based on serial killers, mental asylums, supernatural rituals, vampires and twisted demons.

6. Champion of the Underworld GigaBlox Wild Fight
Released in October 2022, the Champion of the Underworld GigaBlox Wild Fight slot has 6 reels and 4,096 ways to win. Playable from 20p per spin, you head to the depths of the Earth where you help Hades battle new monsters. Using the GigaBlox mechanic, symbols can appear up to 4x4 in size.
With Hades fighting monsters to convert them into Wilds, every fight Hades wins increases the multiplier. In the Free Spins feature, you start with at least 5 free spins but you can gamble for more. The Wild Fight feature is active on each free spin: when Hades wins a fight, you turn more monsters wild which increases the multiplier, up to 25x.
With a 96% RTP rate and 10,000 x bet max wins, Champion of the Underworld (as it’s known) is similar to Hades GigaBlox. If you like venturing into the Underworld, Hounds of Hell and Dark Summoning by Hacksaw Gaming would be my picks.
7. Raptor DoubleMax
Released in August 2021, the Raptor DoubleMax slot takes you to a lost land before time where great lizards clash to reach the top of the Jurassic food chain. With 5 reels and 25 paylines, you can play from 20p per spin.
With Cascading Reels, each symbol drop win doubles the win multiplier. In the Free Spins feature, you begin with up to 16 free spins. Starting with a 1x multiplier, the win multiplier doubles with each win. Importantly, the win multiplier doesn’t reset following a winless spin.
With a 96.01% RTP rate, Raptor DoubleMax comes with 20,000 x bet max wins. If you want prehistoric-themed slots, Blueprint Gaming’s Primal Megaways, 4ThePlayer’s 10000 BC 2 DoubleMax and Playtech’s Jackpot Giant should do the trick.
8. Rainbow Ryan 2
Released in February 2024, the Rainbow Ryan 2 slot is an Irish luck-themed game with 6 reels and 4,096 ways to win. Set in an Irish pub on St. Patrick’s Day, you can play from just 10p per spin. With Synced Reels where symbols match on up to 6 reels, there is a Louder feature where a random multiplier from 2x and up can apply for that spin.
There is an Encore Respins feature where you get a re-spin with a 1 Synced Reel. In the Free Spins feature, you start with up to 20 free spins: you’re guaranteed at least 2 Synced Reels on each free spin. Look out for Green Clover symbols as you’ll trigger the Encore Respin where more reels become synced (up to 6).
Finally, there is a Golden Pot Jackpot Wheel which offers 4 fixed jackpots up to 2,000 x bet. With a 94% RTP rate, Rainbow Ryan 2 has 20,000 x bet max win potential.

9. Florageddon!
Released in October 2022, the Florageddon! slot sees you head to a verdant world where you experience the doom of human civilisation. Played on 5 reels and 243 ways to win from 20p per spin, there are 2 sets of multipliers which apply to left to right and right to left wins respectively. Both ways wins are subject to the sum of both multipliers! A dropdown win also increases the multipliers.
Every 4th consecutive dropdown win gives you a Special Reward: they include multiplier boosts up to 10x, double wilds, wild stacks and an extra life. In the Free Spins feature, you begin with up to 11 free spins. Special Rewards apply from the 3rd consecutive dropdown win and multipliers don’t reset either.
With a 96% RTP rate, Florageddon! comes with 10,632 x bet max wins. If you like apocalypse-themed slots, xWays Hoarder xSplit, Apocalypse and xWays Hoarder 2 from Nolimit City would be my suggestions.
10. Blood Moon Wilds
Released in May 2020, the Blood Moon Wilds slot has a werewolf/Victoria theme and is played with 5 reels and 20 paylines from 10p per spin. Set in New Orleans, all high value character symbols transform into Werewolf Wilds when the Lunar Calendar displays a full moon.
In the base game, there are 4 randomly-triggered features which give you random wilds, random multipliers up to 5x, more free spin symbols (so you can trigger the Free Spins feature) and a full moon from the Lunar Calendar. With the Free Spins feature, you begin with up to 20 free spins. The 4 random base game features can also trigger with the exception of the full moon which is replaced by several blood moons. These transform high-value symbols into sticky wilds.
With a 96.2% RTP rate, Blood Moon Wilds comes with 2,130 x bet max wins. If you’re into werewolves, Pragmatic Play’s Curse of the Werewolf Megaways would be my pick: it comes with a high 96.5% RTP rate and 40,976 x bet max win potential.
