What is Yggdrasil Gaming?
Yggdrasil Gaming was founded in 2013 in Malta (headquartered in Sliema) by Fredrik Elmqvist, who left a senior role at NetEnt to start the new venture.
The studio offers hundreds of in-house titles, built on Yggdrasil's proprietary iSENSE 2.0 HTML5 platform.
It also runs YG Masters, a partner programme where other studios release games through Yggdrasil's own distribution and branding, so not every "Yggdrasil" title is built in-house.
Signature mechanics include the Splitz reel-splitting feature and BOOST, a set of in-game promotional tools (tournaments, cash races) that operators can run on top of Yggdrasil titles.
In 2025 Yggdrasil signed a new content-distribution partnership with Bragg Gaming Group to expand into markets including the Netherlands, Spain, Croatia and Serbia.
This is a commercial aggregation deal, not an acquisition, and Yggdrasil continues to operate as its own studio brand.
In terms of licensing, Yggdrasil Gaming Limited holds UKGC account 44137 (Casino Remote licence, active since 22 December 2015), alongside a Malta Gaming Authority licence and further European registrations.
Best Yggdrasil Gaming casinos to play in the UK
The table below provides a comparison between the best Yggdrasil online casinos. All four are UKGC-licensed brands that run a Yggdrasil catalogue.
Online casino |
Best for |
|---|---|
Betway |
Best for a mainstream, all-round slots lobby that includes a Yggdrasil lineup |
Duelz |
Best for the widest software roster of the four - 50+ studios including Yggdrasil |
Knight Slots |
Best for a SkillOnNet-run brand with a confirmed, dedicated Yggdrasil lineup |
Mega Riches |
Best for jackpot-focused play on the Videoslots platform - one of Yggdrasil's earliest operator partners |
Betway
Betway is the pick for players who want Yggdrasil sitting inside a broad, mainstream software lineup rather than a niche-studio-only site.
Betway offer over 400 games from a software list that spans Microgaming, NetEnt, Playtech, Pragmatic Play, Evolution, Play'n GO, Red Tiger and Yggdrasil.
The Betway Casino promo code offer provides new users with a 100 per cent matched deposit up to £50, while the casino apps are some of the highest-rated on this list, with reviews of 4.7 on the App Store and 4.2 on the Google Play store.
Betway’s range of payment methods give customers plenty of scope for deposits and withdrawals, indeed it is one of the best instant withdrawal casinos available among UK operators.
Verdict: Betway is a solid, familiar first stop if you want Yggdrasil titles alongside all the other big-name suppliers in one lobby.
Duelz
Duelz is a good choice for players who want Yggdrasil games as it provides a gamified casino built around quests and challenges.
They work with 50+ studios, from tier-one names (NetEnt, Pragmatic Play, Evolution, Games Global) to specialist ones, with Yggdrasil sits confirmed among them.
The Duelz Casino welcome offer provides new users with up to 140 free spins, though the lack of a casino app on either Apple or Android devices is a notable negative.
Verdict: Duelz Casino is worth a look if variety and a gamified format matter to you as much as the Yggdrasil catalogue itself.
Knight Slots
Knight Slots is a good choice for players who want Yggdrasil titles on a straightforward, mobile-friendly UK brand rather than a sprawling multi-thousand-game lobby.
The operatot offers over 2,000 games, with Yggdrasil confirmed among its listed software developers alongside NetEnt, Pragmatic Play and Evolution.
The Knight Slots casino welcome bonus gives new users 50 free spins and a deposit match up to £30 when they play with £10.
However, like Duelz, no casino app is available on iOS or Android. However, Knight Slots is one of the standout pay by mobile casinos available, highlighting its strengths for the diverse range of payment methods offered.
Verdict: Knight Slots is a clean, no-frills option if you want Yggdrasil without wading through an oversized catalogue.
Mega Riches
Mega Riches is worth considering for players chasing big jackpot slots who also want Yggdrasil in the mix, via one of the studio's original operator relationships.
Mega Riches runs on the Videoslots platform – Yggdrasil signed a full-catalogue supply deal with Videoslots back in 2014 – and it leans into progressive jackpots and high-volatility titles. It ranks highly among jackpot casinos available online, even against more established brick-and-mortar venues.
The Mega Riches casino welcome bonus offer gives new users a £25 bonus on their first deposit, and users will find plenty of promos of existing customers once signed up.
Verdict: Mega Riches is a good fit if jackpot hunting is your main draw and Yggdrasil is a welcome extra rather than the whole reason you're there.
Key points to know
Below, we’ve run through some of the key things to consider when playing at any Yggdrasil online casino:
Games: Look for Vikings Go Berzerk (and its Vikings Go to Hell/Vikings Go Wild sequels), Valley of the Gods and the Joker Millions progressive jackpot. These give the clearest signal that a casino carries Yggdrasil content.
YG Masters: Some ‘Yggdrasil’ branded titles are actually made by third-party partner studios releasing through Yggdrasil's own distribution and brand, and are not built in-house. This is worth knowing before assuming every title shares the same house style.
Licensing: Yggdrasil itself must hold a UKGC software licence (account 44137), separate from the casino brand's own operating licence. Tell readers they can check either licence on the UKGC public register.
Bonus wagering cap: The UKGC capped bonus wagering requirements at a maximum of 10x, effective 19 January 2026.
Common mistakes with Yggdrasil Gaming casinos
There are several misconceptions that players can come across when using an top Yggdrasil online casinos. These include:
Assuming Yggdrasil has a catalogue the size of Microgaming's or Pragmatic Play's: It's a comparatively small, quality-led studio, not a volume producer, so casinos will list far fewer Yggdrasil titles than from bigger suppliers.
Assuming every "Yggdrasil" branded slot was built entirely in-house: A number arrive via the YG Masters partner programme, so mechanics and volatility can vary title to title even under the same branding.
Confusing Yggdrasil's 2025 content-distribution partnership with Bragg Gaming Group for an acquisition: It's a commercial aggregation deal, not a change of ownership; Yggdrasil remains its own studio brand, majority-owned by Bridgepoint since 2021.
