Yggdrasil - Developer Overview
Yggdrasil Gaming burst onto the online gaming scene in 2013, founded by Fredrik Elmqvist, a former CEO of NetEnt. Headquartered in Malta with offices across Europe, the studio took its name from Norse mythology Yggdrasil being the immense cosmic tree that connects the nine worlds. It's a fitting name for a company that has consistently tried to bridge the gap between conventional slot design and something altogether more cinematic.
What set Yggdrasil apart from the start was a refusal to play it safe. While many studios were content to churn out fruit-themed five-reelers, Yggdrasil invested heavily in 3D graphics, original storylines, and mechanical innovation. Their proprietary iSENSE framework allowed them to deliver visually rich games across devices at a time when mobile optimization was still a genuine challenge for most developers.
Over the years, the studio has picked up a stack of industry awards multiple EGR B2B Awards for Innovation and Slot Provider of the Year among them. With 59 titles available to try on Slottomat, Yggdrasil has built a catalogue that punches well above its weight relative to some of the longer-established names in the industry.
Game Style and Design Philosophy
If you were to sum up Yggdrasil's approach in a single word, it would be atmosphere. These are games designed to be experienced, not just spun through. The art direction is consistently top-tier hand-crafted environments, fluid character animations, and soundtracks that genuinely complement the theme rather than serving as forgettable background noise.
Mechanically, Yggdrasil tends to favour medium-to-high volatility designs with layered bonus structures. They're fond of progression systems within free spins rounds, where each successive trigger or collection pushes the feature further. Their Vikings series is perhaps the best example of this philosophy games that reward patience with escalating drama.
The studio also introduced several proprietary mechanics that have become signatures:
- Splitz Symbols that split to reveal multiple icons, dynamically expanding the ways to win mid-spin.
- MultiMAX A multiplier system that can stack across multiple free spin triggers.
- GigaBlox Oversized symbols that can cover huge portions of the reel set, creating visually dramatic moments.
- PopWins Winning symbols pop and are replaced by two new ones, expanding the reel height with each successive win.
These aren't gimmicks for the sake of it. Each mechanic fundamentally changes how a game plays and what you're watching for on every spin. It's this willingness to rethink base-level slot architecture that keeps Yggdrasil relevant in an increasingly crowded market.
Top Yggdrasil Slots
Wilhelm Tell
Wilhelm Tell sits at the top of Yggdrasil's RTP table with a generous 97%, paired with medium volatility. Based on the legendary Swiss folk hero, the game features a Walking Wilds mechanic where wilds move across the reels with each spin. There's genuine tension in watching a wild arrow work its way across the grid, and the free spins round triggered by landing three crossbow scatters adds linked reels into the mix. It's one of Yggdrasil's more understated titles visually, but mechanically it's one of their smartest.
Aldo's Journey
Aldo's Journey follows an adventurer across four different worlds, each with its own distinct bonus feature. At 96.5% RTP and medium volatility, it's a well-balanced game that keeps things interesting through variety rather than sheer firepower. The world map mechanic means you're never quite sure which bonus you'll land in, and each one plays differently from random wilds to multiplier trails. It's the kind of slot that rewards extended play sessions in demo mode because there's genuinely a lot to discover.
Jambo Cash
Jambo Cash brings an African safari theme with high volatility and a 96.47% RTP. The game uses a collect mechanic where money symbols and multipliers combine during the bonus round, and the results can be genuinely explosive. The presentation is warm and vibrant all golden sunsets and lush savannah and the base game keeps things moving with a decent hit rate despite the high variance label. One of Yggdrasil's stronger recent releases.
Valley of the Gods
Valley of the Gods is set in ancient Egypt yes, another Egyptian-themed slot but Yggdrasil's execution elevates it well beyond the clich. It uses a blockers mechanic where winning combinations remove stone blocks from the grid, gradually revealing more active positions. At 96.2% RTP with medium volatility, it has an almost puzzle-like quality that most slots lack entirely. The scarab collection system that unlocks multipliers and extra lives adds a layer of progression that makes every spin feel consequential.
Vikings Go Berzerk
Vikings Go Berzerk is arguably Yggdrasil's most iconic title, and for good reason. The 96.2% RTP and medium volatility numbers don't tell the full story this is a game built around a rage meter that fills across spins, with each Viking character potentially going berzerk during free spins to become a sticky wild. The sequel treatment and continued player interest years after launch speak to how well the core loop works. The sea-battle bonus round remains one of the most visually spectacular features in any online slot.
Brawl at the Redcap Inn
Brawl at the Redcap Inn leans into a fantasy tavern brawl theme with high volatility and a 96.04% RTP. It's a chaotic, entertaining game where the GigaBlox mechanic drops massive symbols onto the reels up to 6x6 in size during free spins. The bonus round feels genuinely unpredictable, which is exactly what high-volatility players want. The art direction deserves special mention too; the gnome characters and their ramshackle pub are packed with personality.
Raptor
Raptor">Raptor pairs a dinosaur theme with high volatility and the portfolio's average RTP of 96.01%. The base game features a Giga Rise mechanic where symbols can clone themselves across reels, and the free spins come in two flavours one favouring frequent small wins, the other chasing larger payouts. It's a solid choice for players who like having some control over their bonus round experience.
CherryPop
CherryPop">CherryPop uses Yggdrasil's PopWins mechanic, where winning symbols burst and are replaced by two new ones, expanding the reels from a starting 5x3 layout up to 5x8. At 96% RTP with high volatility, the game has a deceptively simple fruit theme that masks a genuinely innovative play structure. Chain reactions can build impressively, and watching the reels grow taller with each successive pop creates a momentum that few other mechanics can match.
2 Gods Zeus vs Thor
2 Gods Zeus vs Thor pits Greek and Norse mythology against each other in a dual-reel setup. Each side of the screen represents a different deity, and the game's 96% RTP comes with high volatility. It's an ambitious concept essentially two games running in parallel and the clash mechanic where features from both sides combine during the bonus is genuinely thrilling. Not every experimental idea lands perfectly, but you have to respect the ambition.
Rock the Cash Bar
Rock the Cash Bar is the outlier on this list a low-volatility game at 96% RTP with a rock music bar theme. It's proof that Yggdrasil can do accessible, steady-paying slots when they want to. The feature set is more straightforward than their usual fare, with respins and cash collection keeping things ticking along. If you prefer longer sessions without dramatic swings, this is one of the better options in their catalogue.
RTP and Volatility Range
Across the 59 Yggdrasil titles available on Slottomat, the average RTP comes in at 96.01% right in line with the broader industry standard. What's notable is the range: from Wilhelm Tell's generous 97% down to some titles sitting closer to 95%, there's meaningful variation depending on which game you choose.
The volatility spread is similarly diverse, though Yggdrasil clearly leans towards the medium and high end of the spectrum. Of the top ten games listed above, six carry a high-volatility rating, three are medium, and only one Rock the Cash Bar sits in the low category. This tells you something about Yggdrasil's design priorities: they build games for players who enjoy anticipation, feature chasing, and the possibility of significant swings.
For demo play, this volatility profile is actually ideal. High-volatility games are arguably more interesting to explore in free mode because you can experience the full range of a game's feature set without concern. You can trigger those rare bonus rounds, see how the mechanics escalate, and get a genuine feel for what each game offers at its peak.
It's worth noting that RTP is a long-term statistical measure it describes the theoretical return across millions of spins, not what you'll experience in any individual session. In demo mode, you're playing with virtual credits, so these numbers serve as useful indicators of game design philosophy rather than anything you need to stress about.
