Yggdrasil Slots

We firmly believe that slot design and delivery is about adopting a balanced mix of evolution and revolution. We study the market carefully and have created a broad portfolio of top-performing titles to suit a wide range of needs and tastes. Our distinctive, best performing proprietary slot titles stand out because we consider every detailed element when designing a game so that we deliver the perfect product for each individual market, brand and operator we work with.

At Yggdrasil we love innovating, from our proven math models to our famous detailed in-game visual effects, innovative features and user experience is core to our entire slot development process. That said, we also do not shy away from going back to the roots, re-using some well-proven mechanics, or producing sequels to our most successful games, such as VGB Reloaded, GTF2Valley of the Gods 2 and Easter Island 2. Some players look for innovative mechanics, others only go for the games with features they are familiar with. The key to successfully meeting player needs is to come up with a diverse roadmap where all players find something to enjoy on a regular basis.

Yggdrasils award-winning slots portfolio includes a great mix of strong classics and new awesome games. The strong performers from the early years – Holmes and the Stolen Stones, Golden Fishtank, Vikings go Wild, Joker Millions, Cazino Zeppelin – are still showing exceptional numbers. These games, together with our pioneering promo tools, BOOST, brought us the EGR Rising Star of the Year 2015 and Slot Provider of the Year 2016.

Our more recent smash hits includes titles such as Raptor DoubleMax, Golden Fish Tank 2, Vikings go Berzerk and Valley of the Gods. The user friendly and effective promo tools Missions and Price Drop continue to be popular options for operator campaigns to drive player acquisition, engagement and retention.

During the past years our portfolio has promoted a mix of Game Engagement Mechanic (GEM) innovations and traditional player-favourite mechanics. Notable titles that have been featured on the iGaming tracker are Hades GigaBlox, Valley of the Gods 2, Multifly! and Jackpot Raiders. We are ongoing investing in our pioneering GEMs DoubleMax™,GigaBlox™, MultiMax™, GigaRise™ and Splitz™ with more to look forward to in 2022. 

Player Experience

Standing out from the crowd and ensuring you have content that engages players is crucial today. We always aim to create top-quality games that are widely enjoyed by our players. A key component of this is to create a good understanding of our current and future players. We constantly stay up to date with the ever-changing trends and we also set the new trends with our innovative products. We have also increased our collaboration with streamers to ensure we receive direct feedback on our games from players and can make improvements at any stage of game development.

We are players and know what it takes to make top quality games that deliver great entertainment value. We continue to drive innovation throughout the industry with both our games and our unique proprietary features which have been extremely well received by our fans across the globe. In game development, mechanics are at the core of a slot and need to be fun, engaging and feed players’ curiosity. We combine this with the best art, sounds and cool animations. A well-designed slot is a craftmanship and something we put a lot of thoughts into. The highly competitive slots tab has 100s of releases every month. We always strive to bring the best combination of outstanding game elements together including; mechanics, sound, art, animations – to provide the ultimate player experience.

We are spending significantly more time on math design. It might take months before we are happy with the math of the game before we decide to start the actual production. But when that happens, we have complete confidence in the success of that game. Yggdrasil has during the years been praised for the AAA art and production quality and now we have brought the game mechanics to the same top level.




Mobile usage


A mobile first approach with a sleek UI, lightweight content and quick loading times is priority with the majority of players now betting on mobile devices. Nearly 70% of play on our games now come from mobile devices. As a result, we ensure all our products are optimised for mobile play and offer a superior experience on all mobile devices.

From its release in 2015, our ‚iSense’ HTML5 game client framework for desktop and mobile, has been in the forefront of user experience and is known for its superior game loading time. This approach has been successful as we now see the majority of our turnover generated from mobile channels.

  • In-browser gameplay which offers a near-identical experience to that of a native app
  • Responsive layout to ensure games look great in all resolutions and aspect ratios
  • Players do not have to ‘learn’ the game again when switching device

Table Games

Golden Chip Roulette is a crisp, modern single player roulette where straight bets turn golden and will pay out with a random multiplier from x10 to x500 instead of the normal payout.

Game Engagement Mechanics

Over the years Yggdrasil has done extensive research to ensure a solid blueprint is engraved in our future games to leave nothing to chance. One of the most critical focal points has been on our Game Engagement Mechanics (GEMs). Our efforts have been in placing big bets on a handful of proven innovative mechanics we know will work and refining them for excellence along the way. Each of our GEMs frameworks offers a unique experience while still hitting the mark on what our audience know, understand, and love, and we are excited to share this exciting journey to success!

To capitalize on our IPs and optimize value creation, we extended our YG Masters offering with licensing out our GEMs enabling Masters’ partners to create games based on all our high performing mechanics.

This takes our partnership collaborations to the next level and will speed up realization of business strategies.

  • DoubleMax™

    DoubleMax™ is powering the success of our hugely popular Raptor DoubleMax™.

    This amazing GEM doubles multipliers on each cascading win with no limit revealing enormous win potential.

  • MultiMAX™

    MultiMax™ debuted with our extremely popular MultiFly! The mechanics are fun, obvious, and appeal to a wide audience.

    Being home to some of the greatest streams, the big wins to be won through the multiplier chain effect is anything but unknown to players. This straightforward easy to implement framework is guaranteed to create success and integrate on any theme, allowing for both efficiency and quality in your productions.


    Splitz™ offers a fresh layer of excitement to Yggdrasil slot releases boosting player engagement with massive win potential.

    The first Yggdrasil game to offer the Splitz™ mechanics is Temple Stacks with +200,000 ways to win! Neon Rush Splitz™ was our second Splitz™ title with its fun, visual-heavy theme and potential for lucrative wins through both the Splitz™ mechanic and the six jackpots available in the title.


    Gigablox™ offers entertainment in every spin with intuitive win potential – the bigger the blox, the bigger the win potential at stake!

    The first launched GigaBlox™ game is Lucky Neko with dynamic reels spawning gigantic blocks sized up to 6×6 stacked! Our Second GigaBlox™ release Hades builds off the first, introducing GigaBlox™ battles, a truly innovative gaming experience!


    GigaRise™️ debuted in Atlantean GigaRise™️ release, where players were introduced to a brand new, towering 8×5 slot format.

    Before they can get too excited about the mouth-watering win potential, there’s work to be done! Special Bonus symbols will be required to increase a reel’s height (in this case, Trident symbols, with regards to Yggdrasil’s inaugural GigaRise™️ release). A Bonus symbol will raise the reel by one position, all the way up to eight for maximum ways to win! Subsequently, a further Bonus symbol landing on a maximum reel will award a Bonus Game session where any single symbol landing on winning line can award cash wins, Free Spins or one of five Jackpots.


The classic games Joker Millions and Empire Fortune feature a global mega-jackpot that has paid out a total value of €40 million. The biggest Jackpot to date on Joker Millions is €7,8 million and the biggest jackpot on Empires Fortune €5,2 million. The total number of Jackpot fallouts amount to +426,000.

We also have numerous local jackpot games including Holmes and the Stolen Stones, Jackpot Raiders and Jackpot Express. All our are jackpot games are designed to have a deep gameplay besides the jackpot. There is always an interesting game mechanic or bonus game to keep the interest up while grinding for the jackpot.

We are regularly releasing local jackpot games that are using the same jackpot pools that are already up and running. Less maintenance for us and operators, bigger jackpots for the players, or simply put win-win-win.


Promo Tools

  • •  Latest extension to our BOOST promotional toolkit beyond Missions, Tournaments, Prize Drops and Free Spins

    •  Our most configurable and adaptable BOOST tool

    •  Natural affinity with players that like jackpot slots

    •  Increases game stickiness (retention)

  • Tournaments with leaderboard was our first flagship promo tool. The success is in the details. The winning critera is to have the highest win multiple. This means you can play only 1 round and still win. Comparing to other tournament formats, where the player that spends the most money almost always wins. Our Tournament allows you to enter late, play on your preferred bet size, and sitll have a chance to win the top prize.


    At the time, all similar tools were clunky to use and did not have the Leaderboard inside the game. This makes all the difference for the player, compared to going to an external URL and refresh a web-page to see your current position in the tournament. The tournament also features a raffle feature at the end of the tournament, where every single participant gets a chance to win something.

  • Prize Drop is as simple as it is effective. Operators decide on the amount of money that should go out during a fixed time period to the players of selected games.

    The money is randomly distributed to the players evenly during the promotion period, using a sophisticated math formula.

  • Missions is an extension of the tournament. Instead of competing for getting the highest wins, the players compete for completing objectives in 3 different games. The player that completes the objectives in fewest spins wins. This is more advanced than the regular tournament, but gives the players more variation and ‘small victories’ while competing.

    All three tools have great player value and are easy to use, making them go-to options for promo campaigns.

  • Brag is a functionality that enables you to save best wins and share them with friends via an URL. The URL will bring up the game and replay that amazing round.


Our client portal Source will enable you to explore new games and discover new ways to entertain your players while taking maximum advantage of games, promotions and BOOST tools. The focus in on automatization and customization, whilst being personalized for each user.
