Yggdrasil Gaming Award-Winning Online Slot Provider

Last updated: 2026-05-10

Quick take: Best for players who want polished, feature-rich slots with RTPs of 96%–97% and mechanics you won't find elsewhere.

Yggdrasil Gaming builds some of the most distinctive slots online. Their games pair studio-quality visuals and immersive audio with proprietary mechanics that have been widely copied by competitors. At Slottomat, you can try any Yggdrasil title for free—no download, no deposit needed.

The History of Yggdrasil Gaming

Yggdrasil Gaming was founded in 2013 by Fredrik Elmqvist, who had previously served as CEO of NetEnt. The company is based in Malta. Its name comes from Norse mythology—the cosmic tree that connects different worlds—a theme you'll spot across several of their titles.

The studio grew quickly and has been named Slot Provider of the Year multiple times at major industry events. Their iSENSE 2.0 HTML5 framework was an early industry standard for cross-device play, letting players move between desktop and mobile with no loss in quality or features.

In 2019, Yggdrasil launched the YG Masters programme. It lets independent studios build games on Yggdrasil's technology and distribute through their network. This brought in partner studios like AvatarUX, who introduced their own PopWins mechanic into the wider Yggdrasil library while keeping quality consistent.

Our Yggdrasil collection covers mythology, adventure, classic fruit themes, jackpots, and seasonal titles. Here's a quick overview:

Wilhelm Tell

Wilhelm Tell carries the highest RTP in our Yggdrasil collection at 97%—well above the standard 96% industry average. Based on the Swiss folk legend, this 5-reel, 20-payline slot features stacked and nudging wilds. The free spins bonus lets you pick your risk level: 10 spins at 5× multiplier, 5 spins at 10× multiplier, or 1 spin at 50× multiplier. Medium volatility; max win 7,500× your stake.

2 Gods Zeus vs Thor

2 Gods Zeus vs Thor was developed by 4ThePlayer through the YG Masters programme. Its DualSpin mechanic offers two spin buttons—red (Zeus/Greek) and blue (Thor/Norse)—each paying in opposite directions across 2,048 ways. The bonus triggers on 3 scatters and awards Win Spins where every spin guarantees a win, with the multiplier climbing each time your chosen color lands. RTP is 96.5%.

Hades Gigablox

Hades Gigablox runs the Gigablox mechanic across a 6-reel, 6-row, 50-payline grid. Oversized symbol blocks from 2×2 up to 6×6 can appear on any spin and cover large sections of the grid. Free spins build a Cerberus Multiplier through progressive Wild Hunts: hit enough and the multiplier climbs from 2× to 10×. RTP is 96%; max win is 11,129×.

Medusa: Fortune and Glory

Medusa: Fortune and Glory approaches the Gorgon myth with detailed character animation and a varied bonus feature set. At 96% RTP, the production quality rivals the highest-budget releases in the industry. The artwork and animated sequences are among the most detailed in the Yggdrasil catalog.

Valley of the Gods 2

Valley of the Gods 2 builds on the original Egyptian-themed title with a six-reel expanding grid. Consecutive wins remove scarab blockers, growing the layout from 240 starting ways up to 20,160 ways at full expansion. Three scarab colors reward you differently: red scarabs grant extra lives, blue scarabs add win multipliers, and golden scarabs place a wild on a random reel. RTP is 96%.

Yggdrasil Game Style and Features

Yggdrasil develops proprietary mechanics rather than adapting existing ones. Several of their formats have since been adopted across the wider industry.

  • Gigablox. Oversized symbol blocks from 2×2 to 6×6 land on the reel grid, creating large cluster wins. Featured in Hades Gigablox and Lucky Neko Gigablox.
  • PopWins (AvatarUX / YG Masters). Winning symbols pop and are each replaced by two new symbols, expanding the reels on every win. Featured in BountyPop, CherryPop, and Wildpops.
  • Expanding Layouts. Some games grow their reel grid through consecutive wins. Valley of the Gods 2 expands from 240 up to 20,160 ways by clearing scarab blockers.
  • Multiplier Free Spins. Several Yggdrasil titles let you choose your free spins bonus tier. Wilhelm Tell goes up to 50× on a single free spin.

Production quality is where Yggdrasil consistently stands apart. Every release features hand-crafted artwork, smooth animation sequences, and carefully composed soundtracks. From the icy atmosphere of Frost Queen Jackpots to the festive warmth of Carol of the Elves, each game builds a complete world rather than reusing a generic template.

Diverse Themes

Yggdrasil covers a wide range of themes in their portfolio. On Slottomat.com you will find:

Yggdrasil RTP Range and Fairness

Yggdrasil slots on Slottomat.com return between 96% and 97%—comfortably above the industry average. Wilhelm Tell leads at 97%; 2 Gods Zeus vs Thor returns 96.5%; and the remaining titles each sit at a solid 96%.

Yggdrasil holds licenses from multiple respected regulatory bodies. All games are independently tested and certified for fairness. Certified random number generators ensure every spin produces a truly random outcome, and player protection tools are built directly into the platform.

Why Players Love Yggdrasil Slots

  • Proprietary mechanics: Gigablox, PopWins, expanding layouts, and multiplier free spins keep gameplay fresh. Each new release tends to bring something new rather than recycling familiar formats.
  • Exceptional production: Cinematic intros, detailed character animations, and atmospheric soundtracks make every session feel premium rather than generic.
  • Strong RTPs: Return rates of 96%–97% give players real value. Wilhelm Tell's 97% is one of the highest among major online slots.
  • Mobile-first HTML5: Built on iSENSE 2.0, every Yggdrasil game runs without compromise on smartphones and tablets—full visuals, full features, any screen size.
  • Volatility variety: Medium-variance titles like Wilhelm Tell suit steadier bankrolls; high-volatility games like Vikings Go Berzerk suit big-win chasers. Both ends are well covered.
  • Layered bonus features: Free spins choices, growing multipliers, and game-specific mechanics keep rounds engaging. Vault of Fortune and Jackpot Express have particularly rewarding bonus rounds.

Yggdrasil Gaming Slots Overview

Yggdrasil Gaming: Pioneering Innovation in Online Slots Since 2013

Named after the legendary World Tree from Norse mythology that connects all nine realms, Yggdrasil Gaming has lived up to its mythical namesake by bridging the gap between players and extraordinary gaming experiences. Founded in 2013 in Sweden, this award-winning developer has rapidly ascended to become one of the most innovative and respected names in the online casino industry, earning the coveted title of Innovator of the Year an unprecedented four consecutive times at the International Gaming Awards.

With headquarters in Malta and offices spanning Gibraltar, Stockholm, and Poland, Yggdrasil operates under licenses from the Malta Gaming Authority, and Gibraltar Regulatory Authority. The company holds ISO 27001 certification, demonstrating its commitment to the highest data security standards and player protection protocols.

Revolutionary Game Mechanics That Changed the Industry

Yggdrasil has distinguished itself through proprietary Game Engagement Mechanics (GEMs) that deliver unique gameplay experiences impossible to find elsewhere. These innovative features have redefined what players can expect from modern slot games, setting new industry standards that competitors strive to match.

GigaBlox: Massive Symbols, Massive Wins

The groundbreaking GigaBlox mechanic introduces colossal symbols ranging from 2x2 up to enormous 6x6 blocks that cover multiple reel positions simultaneously. This innovation dramatically increases the probability of forming substantial winning combinations across multiple paylines at once. When a 6x6 symbol lands, it effectively becomes 36 matching symbols, creating spectacular win potential that keeps players on the edge of their seats.

MultiMAX: Multipliers That Multiply

With the MultiMAX feature, each reel carries its own multiplier that can stack or combine with others to create breathtaking total wins. Games like MultiFly! showcase this mechanic brilliantly, allowing players to accumulate multipliers on every reel through consecutive wins, with combined multiplier potential reaching staggering heights that can transform modest bets into life-changing payouts.

DoubleMax and Splitz: Even More Ways to Win

The DoubleMax mechanic doubles multipliers with every cascading win, offering exponential growth potential that can skyrocket with each successive tumble. Meanwhile, the innovative Splitz feature splits symbols into multiple identical symbols, unlocking over 200,000 ways to win in games like Syncronite. These mechanics exemplify Yggdrasil's commitment to creating mathematically sophisticated yet thrilling gameplay.

The Legendary Vikings Go Series

Few slot franchises have captured players' imaginations quite like Yggdrasil's epic Vikings Go series. This collection of Norse adventure slots has become synonymous with quality, innovation, and entertainment, spawning multiple sequels that each bring unique twists to the formula while maintaining the core excitement that made the original a phenomenon.

Vikings Go Wild

The game that started it all, Vikings Go Wild features 5 reels, 4 rows, and 25 paylines with an impressive 96.3% RTP. The signature feature sees fierce Viking warriors battling sea monsters during free spins, with successful victories transforming these heroes into sticky wilds that remain locked in place for the duration of the bonus round. The Treasure Chest appearing on reel 5 adds extra anticipation to every spin.

Vikings Go Berzerk

Raising the stakes considerably, Vikings Go Berzerk introduces the Rage collection system and Berzerk Mode, where Vikings can enter a frenzied state for even more powerful bonus features. With a 96.1% RTP and enhanced volatility, this sequel delivers the same 5x4 grid with 25 paylines but amplifies the intensity. The Ragnarok Free Spins feature offers players a taste of the mythological end times with extraordinary win potential.

Vikings Go To Hell

Taking the brave warriors into the underworld itself, Vikings Go To Hell features a two-level free spins system where Vikings battle demons in the base game and Berzerk free spins mode. With a 96.1% RTP and the same proven 5x4, 25-payline structure, this installment adds demon fights to the base game and respins that can trigger randomly, keeping the action intense even outside the bonus rounds.

Vikings Go Berzerk Reloaded

The latest evolution in the series, Vikings Go Berzerk Reloaded, refines and enhances the formula with updated graphics, refined mechanics, and a 96% RTP that delivers frequent wins alongside the potential for massive payouts during the enhanced bonus features.

Award-Winning Portfolio of Premium Slots

Beyond the Vikings series, Yggdrasil has created an impressive portfolio of over 260 proprietary games, with the total catalog exceeding 300 titles when including releases from their YGS Masters partner studios. Each game showcases meticulous attention to detail, mathematical precision, and engaging themes that resonate with players worldwide.

Hades Gigablox

Released in October 2020, Hades Gigablox combines Greek mythology with the revolutionary GigaBlox mechanic across 6 reels and 50 paylines. The Wild Hunt Free Spins feature sees Hades himself battling fearsome monsters to convert them into wild symbols. With a solid 96% RTP and maximum wins of 11,129x bet on every free spin, this game exemplifies how Yggdrasil merges innovative mechanics with compelling themes.

Valley of the Gods

Journey to ancient Egypt in Valley of the Gods, where unique reel mechanics create an unforgettable gaming experience. Starting with blocked positions that unlock as you achieve wins, the game evolves dynamically with each spin. The 96.2% RTP ensures fair returns, while the innovative progression system keeps gameplay fresh and engaging throughout extended sessions.

Holmes and the Stolen Stones

This detective-themed mystery adventure offers one of the highest RTPs in Yggdrasil's portfolio at an impressive 96.8%. Following the famous sleuth through London, players collect colored gems that trigger bonus features including free spins with enhanced multipliers. The pick-and-win bonus rounds add interactive elements that complement the compelling narrative.

Atlantis Megaways

Diving into underwater riches, Atlantis Megaways leverages the popular Megaways mechanic under license, with each spin changing the number of symbols per reel to create thousands of possible winning combinations. The stunning aquatic visuals and cascading wins mechanic ensure every spin holds the potential for extended winning sequences.

Raptor DoubleMax

Transporting players to a prehistoric world, Raptor DoubleMax showcases the DoubleMax multiplier mechanic that doubles with every consecutive win. This volatile adventure offers thrilling gameplay where patient players can build multipliers to extraordinary heights, resulting in explosive win potential when everything aligns perfectly.

YGS Masters: Empowering Independent Innovation

Launched in 2018, the YGS Masters program represents Yggdrasil's visionary approach to industry collaboration. This semi-open, invite-only platform enables carefully selected independent game studios to develop and distribute titles through Yggdrasil's extensive network, accessing their promotional tools and infrastructure while maintaining creative independence.

Partners gain access to BOOST, Yggdrasil's sophisticated suite of in-game promotional tools that enable tournaments, cash races, missions, and network campaigns.
