Yggdrasil is one of the most easily recognised iGaming names out there, and it’s all thanks to feature-heavy math models and unique gameplay mechanics like Splitz and Gigablox, which you won’t find anywhere else.
Instead of massive grids and bloated paylines, Yggdrasil’s best slots are characterised by tight gameplay loops, unique features, and bonus rounds that captivate the players and keep them at the edge of their seats.
I’ll examine the five most popular Yggdrasil slots, their core gameplay mechanics, stats breakdown, and figure out if they’re worth checking out.
How I Picked These Yggdrasil Slots
Before I even looked at Yggdrasil’s gaming library, I decided on three core criteria I’d use to evaluate the slots. These included:
- Unique mechanics instead of boring templates – Instead of picking slots based on templates you’ve already seen a thousand times, I focused on Yggdrasil best slots with unique mechanics, such as rage meters, featured picks, sticky multiplier wilds, and more.
- The higher the RTP, the better – I also narrowed down our selection based on RTP values stated on the official Yggdrasil website, since I know how important a high-RTP slot is in the long run.
- Popularity over the years – Yggdrasil has roughly 150 games to its name. Instead of basing our list on new releases, I primarily focused on games that have stayed popular over the years.
The Top Yggdrasil Slot Games
Without further adieu, here are overviews of the five best Yggdrasil slots to play in this year:
Vikings Go Berzerk
- RTP: 96.10%
- Volatility: Medium-High
- Release date: November 23, 2016
Vikings Go Berzerk is perhaps the most popular slot out of Yggdrasil’s entire Vikings series. It’s based on the well-known concept of individual rage meters for every Viking, which fills as you win rounds in the base game.
Once the meter is filled, one of your Vikings will enter his Berzerk Mode during Ragnarok free spins. Doing so guarantees he’ll defeat the siren and turn into a sticky wild for the rest of the round.
The game comes with 96.10% RTP and medium-high volatility. It plays in a 5×4 grid with 25 fixed paylines, and has a maximum win up to 4,000x. If you appreciate unique mechanics over massive-but-complex paylines and gigantic grids, Yggdrasil’s Vikings Go Berzerk is definitely worth checking out.
Gem Rocks
- RTP: 96.20%
- Volatility: High
- Release date: February 22, 2018
The second Yggdrasil slot worth talking about is Gem Rocks. It was one of their biggest releases in the first half of 2018, featuring 96.20% RTP and high volatility. It’s best suited for players who don’t mind an occasional dry spell between hefty wins.
This slot is also Yggdrasil’s first mega-line title, featuring a 6×4 grid with 4,096 paylines. The biggest issue most people have with Gem Rocks is the fact that it doesn’t feature scatters, wilds, and a proper bonus round. Instead, it focuses on cascading wins which can turn into Monster Rock blocks that take up to 4×4 grid space.
Valley of the Gods
- RTP: 96.20%
- Volatility: High
- Release date: August 24, 2017
Next up, I have Valley of the Gods. This slot was released in 2017 and comes with 96.20% RTP, a 5×5 grid, and high volatility. There are no free spins, just 45 paylines in the base game. However, every single win triggers a respin and clears scarab blockers, paving the way for up to 3,125 paylines, and grants extra lives and multipliers.
The game features Ancient Egyptian mechanics and visuals, including the great gods Horus and Anubis. Its massive worldwide popularity helped pave the way for the sequel, Valley of the Gods 2, released on September 24th, 2020.
Rainbow Ryan
- RTP: 96.30%
- Volatility: Medium-High
- Release date: July 24, 2017
Rock and roll-themed slots aren’t a common sight; Irish rock and roll-themed slots are even less so. But, Rainbow Ryan is a notable exception, featuring a 6×4 grid with a whopping 4,096 paylines.
It features the infamous Rainbow Reels mechanics that randomly sync two reels (reels #2 and #6), which then have the exact same symbols. If you trigger free spins, 2+ reels stay in sync every single spin, which creates plenty of opportunities for big wins. The maximum win is 5,100x, which is $510,000 at max stake.
Golden Fish Tank
- RTP: 96.80%
- Volatility: Medium-High
- Release date: February 1, 2016
The last Yggdrasil slot worth checking out this year is Golden Fish Tank. Released in early 2016, this slot plays in a classic 5×3 grid with 20 fixed paylines and a strong underwater/aquarium vibe.
It doesn’t fall too far away from classic slots, which is a surprise considering it’s made by Yggdrasil. That said, Golden Fish tank features scatters, three and more of which trigger free spins. Other features include 18 surfacing objects during free spins and the Golden Bet feature.
With an RTP of 96.80%, Golden Fish Tank is one of the highest RTP slots in Yggdrasil’s arsenal. Last but not least, the maximum win is 2,500x, which is $100,000 at max bet.

Yggdrasil Slots: Worth It?
Long story short; yes, they are!
Yggdrasil has been up and running since 2013, which means the studio has over a decade of experience. As such, it’s only logical to see that they’ve built a large selection of exceptional slots over the years.
They like to think outside of the box instead of forcing the same reusable templates across their games. Some of their slots (such as Valley of the Gods) don’t even have free spins.
Others, like Gem Rocks, have growing symbols. The variation in game mechanics is the key here, which is what makes Yggdrasil slots some of the most sought-after titles at real money online casinos.
