Editor at online-gambling.com Yggdrasil went from startup to lobby fixture faster than almost any studio of its generation. In this Yggdrasil review, we cover the Malta studio behind the Vikings series and GigaBlox: the most popular games, RTP rates, jackpot records, mobile play, and licensing.

Yggdrasil launched in 2013 out of Malta, founded by former NetEnt executive Fredrik Elmqvist, and made its name on visual ambition: 3D-rendered slots that looked a generation ahead of the market. The Vikings series became its calling card, and the Joker Millions jackpot pool made headlines with multimillion-euro drops.
Today the company is as much a technology supplier as a studio. Its GATI framework and YG Masters program let partner studios build and distribute games through Yggdrasil’s network.
Expert Verdict – Is Yggdrasil Worth Playing?
Yes, especially if visuals matter to you. We played across the Vikings titles, the jackpot pair, and the newer GigaBlox releases, and the animation quality still embarrasses bigger studios. Bonus rounds feel authored, with real choices and escalation.
The trade-off is focus: the catalog is smaller than the giants’, and the jackpot games carry noticeably lower base RTPs, which the paytables disclose but casual players often miss.
Best for
- Players who care about animation and art direction
- Progressive hunters – the Joker Millions pool has paid €7.8 million
- Fans of the Vikings series and its rage-meter battles
- Mechanics collectors: GigaBlox, Splitz, MultiMax
Not Ideal for
- RTP purists – the jackpot titles run low base returns
- Live dealer players – Yggdrasil doesn’t produce live games
- Players who want a huge catalog from one studio
Best Yggdrasil Games: Top Picks and Must-Try Titles
Slots dominate, split between in-house releases and the YG Masters partner label. The range of Yggdrasil casino games also stretches to a small RNG table set, including a blackjack game with a fully animated dealer.
The sections below sort the catalog by category, with our picks for the best Yggdrasil games in each. Expect personality over volume; this is a studio that ships fewer, weirder, prettier games.
Yggdrasil Slots: Popular Titles, RTP, and Unique Features
Yggdrasil slots lead with spectacle. The house style is console-grade 3D art over inventive math, from the Vikings’ rage-fueled free spins to MultiFly’s stacking multipliers.
RTP splits cleanly in two. Standard slots sit at a healthy 96%+, while the pooled-jackpot pair trades several base points for its multimillion-euro top prize; check which type you’re spinning.
| Slot Name | RTP | Theme | Volatility | Bet Limits | Max Win Overall |
|---|---|---|---|---|---|
| Vikings Go Berzerk | 96.10% | Viking Battle | Medium-High | $0.25 – $125 | 4,000x |
| Valley of the Gods | 96.20% | Ancient Egypt | High | $0.10 – $100 | 5,800x |
| Holmes and the Stolen Stones | 96.80% | Detective | Low | $0.10 – $100 | Local jackpot tiers |
| Vikings Go Wild | 96.30% | Viking Battle | Low-Medium | $0.25 – $125 | 1,900x |
| MultiFly | 96.30% | Jungle Multipliers | High | $0.10 – $75 | 10,000x |
| Joker Millions | 94.30% | Classic Fruits | Medium-High | $0.25 – $25 | Progressive |
| Empire Fortune | 94.30% | Steampunk Luxury | Medium | $0.10 – $100 | Progressive |
| Gem Rocks | 96.20% | Rock Creatures | High | $0.10 – $50 | 9,217x |
| Cazino Zeppelin | 96.00% | Steampunk | High | $0.20 – $100 | €167,500 |
| Nikola Tesla’s Incredible Machine | 96.20% | Inventor Lab | Medium-High | $0.25 – $75 | 4,100x |
Reading the table: RTP is the long-run return on total stakes, volatility is how it arrives, and the final columns show stake range and ceiling.
Note the jackpot split: Joker Millions and Empire Fortune pay several points under the rest because they feed a shared prize pool. Demo modes let you try any of these Yggdrasil online slots for free, and our guide on how to play slots covers the fundamentals.
RNG Table Games by Yggdrasil
The table set is tiny but full of character: Golden Chip Roulette, Dr Fortuno Blackjack, and Sonya Blackjack lead it, all dressed in far more theme than table games usually get.
Math stays standard, with single-zero roulette at the usual 97.30% (96.80% with the golden chip active) and blackjack above 99% under optimal play.
Table-first players will still want a casino carrying dedicated specialists; these titles are a styled extra rather than the main event.
Live Casino Games by Yggdrasil
Yggdrasil makes no live dealer games. Its closest experiment was Sonya Blackjack, an RNG table with a fully 3D-animated dealer, which shows where the studio’s instincts lie: rendered worlds, not camera feeds.
For real dealers, most lobbies pair the catalog with live specialists such as Playtech, so nothing is lost in practice.
Other Yggdrasil Casino Games: The YG Masters Ecosystem
The most distinctive corner is not a game type but a distribution model. YG Masters partner studios build on Yggdrasil’s GATI framework and ship through its network, adding dozens of third-party titles under the Yggdrasil umbrella.
For players, that means lobbies often mix in-house releases with partner games of varying styles, all carrying the same technical standard. US players see the catalog through an exclusive Aristocrat Interactive distribution deal signed in January 2025.
Exclusive and Branded Casino Games by Yggdrasil
Yggdrasil skips outside licenses almost entirely; its exclusives are homegrown franchises. The Vikings trilogy (Go Wild, Go Berzerk, Go to Hell) built a connected saga with recurring characters and escalating mechanics.
The pattern repeats across the catalog: Holmes chases stones over multiple jackpot tiers, Tesla powers his machine, and the Cazino series gives its steampunk world sequels rather than reskins.
Owning every brand means nothing rotates out of lobbies when a license lapses, and the sagas can keep growing on the studio’s own schedule.
Standout Features, Technology & Innovation
Yggdrasil names and trademarks its mechanics the way other studios name games. Four carry most of the catalog.
- Reels – GigaBlox Oversized symbols up to 6×6 on the biggest grids land whole, turning single spins into screen-filling hits. The mechanic now appears in partner-studio games too, licensed like a brand.
- Battles – The Rage Meter The Vikings series charges a meter through combat wins; full rage sends that Viking berzerk into free spins, guaranteed to win his battles and stick as a wild. It made progression a selling point years before it was standard.
- Symbols – Splitz and MultiMax Splitz packs multiple symbol copies into one position; MultiMax removes the win cap, with multipliers that keep climbing. Both are trademarked and licensed outward.
- Technology – GATI The development framework behind YG Masters gives partner studios a preconfigured toolkit, so third-party games ship with Yggdrasil’s performance profile built in.
Is the toolbox unique? The individual ideas have imitators, but trademarking and licensing mechanics as products remains rare, and it turned a mid-sized studio into a network.
Mobile Experience with Yggdrasil Games
Yggdrasil built for HTML5 from day one, and its early iSENSE framework was pitched squarely at phones. The payoff shows: heavy 3D art that still loads fast on mobile.
Our iOS and Android sessions ran the full animation quality without stutter, and bonus-buy menus and battle meters translate cleanly to touch.
- Yggdrasil Slots on Android – Full visual quality in Chrome or any current browser; nothing to install.
- Yggdrasil on Android Tablet – The 3D art earns the extra inches; Vikings battles are at their best here.
- Yggdrasil on iPhone – Safari runs the desktop math and effects with controls in thumb reach.
- Yggdrasil on iPad – Browser play, no compromises; the detailed reels reward the bigger screen.
Progressive & Fixed Jackpots
Yggdrasil runs a genuine progressive network. Joker Millions and Empire Fortune feed one shared pool, and it has paid at life-changing scale: €7,832,262 on Joker Millions at LeoVegas in November 2018, from a 5 SEK (about €0.50) spin.
Empire Fortune’s own record stands at €5,197,198, won in July 2017 on a phone at Betsson’s NorgesAutomaten. Holmes and the Stolen Stones adds smaller local jackpot tiers for more frequent hits.
| Game Logo | Type | Record Win |
|---|---|---|
| Joker Millions | Progressive – shared pool with Empire Fortune | €7,832,262 – LeoVegas, November 2018, from a €0.50 spin (biggest Yggdrasil jackpot) |
| Empire Fortune | Progressive – shared pool with Joker Millions | €5,197,198 – NorgesAutomaten (Betsson), July 2017, won on mobile |
| Holmes and the Stolen Stones | Progressive – local jackpot tiers | Five local jackpots seeding €40 to €10,000; largest documented hit €68,913 |
Both record wins came at sub-€1 stakes, which is the honest pitch for this pool: the ticket price is small, the base RTP pays for it, and the ceiling is real. For the biggest pooled prizes in the business, Microgaming‘s Mega Moolah network still leads.
Security, Licensing & Fair Play
Yggdrasil holds licenses from the Malta Gaming Authority, the UK Gambling Commission, Gibraltar, and the Isle of Man, and its games ship into further regulated markets through operator and partner certifications. For this Yggdrasil review, the compliance record checked out cleanly across a decade of operation.
Independent laboratories certify the random number generators in every regulated market. Each game publishes its certified RTP in the paytable, including the lower jackpot-game figures.
Casinos carrying the games publish aggregate payout audits, and per-game certificates are available through the testing agencies.
Responsible Gaming Tools & Player Protection
Player protections come from each market’s license plus the host casino’s controls: reality checks, session clocks, and account-level stake or deposit caps where required.
Set limits before you spin, and give the jackpot pair extra respect; low base RTP plus a big dream is exactly the combination limits exist for.
| Reality Checks | Yes (market-dependent) |
|---|---|
| Session Time Tracking | Yes |
| Bet Size Limits | Yes |
| Spin Speed Restrictions | Yes (market-dependent) |
| Autoplay Controls | Yes (market-dependent) |
