Yggdrasil Gaming was founded in 2013 by Fredrik Elmqvist, a former NetEnt executive. The company is headquartered in Malta with additional offices in Sweden, Poland, and Gibraltar. Named after the mythological tree that connects the nine worlds in Norse cosmology, Yggdrasil entered the market with a focus on HTML5 slot development at a time when many competitors still relied on Flash.
The company operates across three product verticals: casino slots, table games, and bingo. Its proprietary iSENSE 2.0 HTML5 framework and GATI (Game Adaptation Tool & Interface) technology power all game development and distribution. Through the YG Masters partner programme, 20+ independent studios create and distribute content via Yggdrasil’s operator network, bringing the total catalogue to 450+ titles accessible through a single API integration.
Bridgepoint acquired Yggdrasil in 2021, providing capital for continued expansion. The company now serves 350+ operators and 700+ online brands across five continents. Industry recognition includes seven consecutive innovation-related awards at the International Gaming Awards (2017–2023), EGR B2B Slot Provider of the Year (2016, 2017), and multiple additional honours totalling 13+ awards.
Yggdrasil holds supplier licences from six major regulators: the Malta Gaming Authority (MGA), the UK Gambling Commission (UKGC), the Gibraltar Gambling Commissioner, the Isle of Man Gambling Supervision Commission, Sweden’s Spelinspektionen, and Romania’s ONJN. Games are additionally certified in Italy, Spain, Denmark, Germany, France, Switzerland, Greece, Belgium, and Argentina, covering 28+ regulated jurisdictions in total.
All titles undergo third-party testing through independent laboratories including GLI, BMM, and QUINEL. The company maintains ISO/IEC 27001 certification for information security, and every game includes mandated responsible gaming features such as session limits, self-exclusion support, and reality checks.
Game Categories
Slots dominate the catalogue, but Yggdrasil also covers table games and bingo. Here is what each vertical includes.
275+ own titles · Average RTP ~96%
The core product. Slots span Norse mythology, Egyptian adventure, steampunk, and original IPs. Each game uses at least one proprietary mechanic (GigaBlox, DoubleMax, Splitz, MultiMAX, PopWins, or others). Payout types include lines, ways, clusters, infinity reels, and scatter pay. Volatility ranges from low to super high, and most post-2022 releases ship with bonus buy functionality.
Small selection · RNG with 3D animation
Yggdrasil offers Sonya Blackjack, Dr Fortuno Blackjack, and Golden Chip Roulette. These use the REDUX™ 3D engine to render motion-captured animated dealers, bridging the gap between RNG and live dealer without requiring a live stream. Sonya Blackjack returns 99.54% under standard rules.
Shared pool · €100k seed
Joker Millions (2015) and Empire Fortune (2016) share a single global progressive pool. The largest recorded payout was €5.2 million on Empire Fortune. The pool reseeds at €100,000 and 5.5% of each bet feeds the jackpot.
75-ball and 90-ball variants
Launched in 2018, the bingo platform integrates with the same BOOST promotional tools used in slots. Availability is limited to operators that specifically carry the bingo vertical.
Yggdrasil’s flagship titles are recognisable by their art direction and distinctive mechanic integrations. The games below appear consistently across operator libraries and player popularity rankings.
| Game | RTP | Volatility | Key Feature |
|---|---|---|---|
| Vikings Go Berzerk | 96.1% | Medium-High | Rage meter progression, Berzerk free spins with sticky wilds |
| Valley of the Gods | 96.2% | High | Scarab-clearing respin mechanic, expanding grid |
| Holmes and the Stolen Stones | 96.8% | Low | 5-tier local progressive jackpot, warehouse bonus |
| Golden Fish Tank | 96.4% | Medium-High | Bonus round with selectable extra wilds and multipliers |
| Raptor DoubleMax | 96.0% | High | DoubleMax™ cascade multiplier (x1→x2→x4→x8…) |
| Cazino Zeppelin Reloaded | 96.0% | Very High | Sticky multiplier wilds, 102,838x max win |
| Multifly! | 96.3% | Medium | MultiMAX™ per-reel multipliers, 10,512x max win |
| Hades GigaBlox | 96.0% | High | GigaBlox™ oversized symbols up to 6×6 |
Around 90% of Yggdrasil slots fall within the 96%–97% RTP range. A few titles exceed that threshold. Note that operators can select from multiple RTP configurations (typically 84%, 90%, 94%, or 96% tiers on post-2022 releases), so always check the in-game help file at your chosen casino before playing.
| Game | Max RTP | Note |
|---|---|---|
| Jokerizer | 98.0% | Requires Jokerizer (big bet) mode; base mode drops to 88.8% |
| Tut’s Twister | 97.1% | Ancient Egypt theme with twister wild feature |
| Beauty & the Beast | 97.1% | Free spins with retrigger, three Golden Bet features |
| Nitro Circus | 97.0% | First branded slot; Nitro Jump bonus game |
| Holmes and the Stolen Stones | 96.8% | Local progressive jackpot with 5 tiers |
| Winterberries | 96.8% | Freeze-and-respin mechanic |
| Fruitoids | 96.7% | Classic fruit theme with multiplier wilds |
Yggdrasil operates a shared global progressive jackpot pool across two titles: Joker Millions (launched 2015) and Empire Fortune (launched 2016). Both games contribute 5.5% of every bet to the same pool, which reseeds at €100,000 after a win. The record payout was €5.2 million on Empire Fortune in 2020, and the pool has paid out roughly €10 million across three consecutive drops.
Both jackpot titles carry an RTP of 94.3%, which is lower than the portfolio average but standard for progressive slots where a portion of each wager feeds the prize pool. Holmes and the Stolen Stones offers an alternative with a local 5-tier progressive at 96.8% RTP, though the jackpot sizes are smaller.
Game Engagement Mechanics
Yggdrasil developed 8+ exclusive slot mechanics under its Game Engagement Mechanics (GEMs) programme. These are licensed exclusively through the Yggdrasil ecosystem and available to all YG Masters partner studios.
Oversized symbol blocks ranging from 2×2 to 6×6 land on every spin, increasing win potential through larger coverage. Debuted in Lucky Neko and now used across 50+ titles.
The multiplier doubles after each consecutive cascade win with no cap (x1, x2, x4, x8, x16…). Raptor DoubleMax demonstrates the mechanic at its peak with exponential growth during free spins.
Mystery symbols split into 2–12 identical pieces, expanding paylines up to 248,832 ways to win. Temple Stacks was the first title to feature this mechanic.
Per-reel multipliers stack with every wild that lands. In Multifly!, chameleons catch fireflies to build multipliers across all five reels simultaneously, reaching a 10,512x max win.
Winning symbols pop and are replaced by two new symbols each, expanding the reel height and adding paylines with every consecutive win.
Available across 100% of tracked Yggdrasil titles — the highest coverage rate of any provider. Players can purchase direct access to free-spin rounds at a predefined bet multiplier where the mechanic is permitted by local regulation.
Every Yggdrasil game is built in HTML5 through the iSENSE 2.0 framework and renders in both portrait and landscape orientation on iOS and Android devices. No app download is required — games load directly in mobile browsers. The GATI integration toolkit enforces cross-platform consistency, so gameplay, RTP, and features remain identical across desktop, tablet, and smartphone.
Most Yggdrasil casinos also optimise their full site for mobile, including deposits, withdrawals, bonus claims, and customer support access. If you regularly play on a phone, test the casino’s mobile interface before depositing to confirm that game loading times and navigation meet your expectations.
Yggdrasil casinos offer standard bonus formats. Welcome bonuses typically combine a deposit match (100%–200%) with free spins on selected slots. Returning players can access reload bonuses (usually weekly or monthly), cashback on net losses, and loyalty or VIP tier rewards at higher deposit levels.
Before claiming any bonus, check whether Yggdrasil slots contribute 100% toward wagering requirements — most casinos count slots fully, but some exclude progressive jackpot titles like Joker Millions and Empire Fortune from bonus play. Also review the maximum bet size allowed while a bonus is active, as exceeding it can void the bonus balance.
Pros & Cons
Yggdrasil’s strengths centre on mechanics innovation and production quality. The gaps are in portfolio scope and max win ceilings.
Pros
Cons
If you want to compare Yggdrasil with other slot-focused providers, these studios offer similarly sized catalogues with their own specialities. Pragmatic Play covers 500+ titles including live dealer and virtual sports. Play’n GO delivers 300+ slots with grid-based mechanics and a strong focus on mobile optimisation. NetEnt, one of the longest-running providers (since 1996), offers a deep library of high-RTP classics alongside live casino content. Each provider holds MGA and UKGC licences.
Yggdrasil’s primary focus is online slots, with 275+ own titles and 450+ total when including YG Masters partner content. The company also offers a small selection of RNG table games (Sonya Blackjack, Dr Fortuno Blackjack, Golden Chip Roulette) and a bingo platform with 75-ball and 90-ball variants.
No. Yggdrasil does not operate a live dealer studio. Its table games use a 3D animated dealer through the REDUX™ engine, which simulates a live experience without a real-time stream. For live dealer content, you will need a casino that also carries a dedicated live provider such as Evolution or Pragmatic Play Live.
Yes. Yggdrasil holds supplier licences from the MGA, UKGC, Gibraltar, Isle of Man, Sweden, and Romania. All games are tested by independent laboratories (GLI, BMM, QUINEL), and the company maintains ISO/IEC 27001 certification for information security. Games include mandated responsible gaming features such as session limits and self-exclusion support.
Jokerizer has the highest maximum RTP at 98.0%, but only when played in Jokerizer (big bet) mode. In standard mode, the RTP drops to 88.8%. The next highest are Tut’s Twister and Beauty & the Beast, both at 97.1%. Keep in mind that operators can select lower RTP configurations, so check the in-game help file at your chosen casino.
Yes. All Yggdrasil games are built in HTML5 using the iSENSE 2.0 framework and work in mobile browsers on both Android and iOS. No app download is required. Games adjust to your screen size automatically and support both portrait and landscape orientation.

The main ones are GigaBlox (oversized symbol blocks up to 6×6), DoubleMax (multiplier doubles on each cascade), Splitz (symbols split into multiple pieces, expanding ways to win), MultiMAX (per-reel multipliers), and PopWins (symbols pop and expand the reel height). These mechanics are licensed exclusively through Yggdrasil and its YG Masters partner studios.
Yes. Joker Millions and Empire Fortune share a global progressive jackpot pool that reseeds at €100,000. The largest recorded payout was €5.2 million on Empire Fortune. Both titles carry an RTP of 94.3%, with 5.5% of each bet feeding the jackpot pool.
YG Masters is Yggdrasil’s partner studio programme. Independent game studios accepted into the programme develop titles using Yggdrasil’s GATI technology framework and distribute them through Yggdrasil’s operator network. Operators with a Yggdrasil API integration receive access to both Yggdrasil’s own catalogue and all YG Masters titles in a single connection. Over 20 partner studios currently participate.
Yggdrasil casinos typically offer welcome bonuses (deposit match plus free spins), reload bonuses, cashback on losses, and VIP or loyalty rewards. Bonus terms vary by casino. Always check whether Yggdrasil slots contribute fully toward wagering requirements and whether progressive jackpot titles are excluded from bonus play.
Cazino Zeppelin Reloaded holds the highest max win at 102,838x your bet. Other high-potential titles include 90K Yeti GigaBlox (90,000x), Gator Gold GigaBlox (30,000x), and Vikings Go Berzerk Reloaded (25,000x).
Yggdrasil suits players who prioritise mechanics innovation and production quality over extreme volatility or live dealer access. If you enjoy GigaBlox, DoubleMax, or Splitz gameplay and want a catalogue where every slot includes bonus buy, this provider delivers consistently. The licensing footprint (MGA, UKGC, Gibraltar, Isle of Man) covers most regulated markets, and the YG Masters network keeps the release pipeline active without compromising curation standards.
The tradeoffs are clear: no live casino, a max win ceiling below Hacksaw and Nolimit City, and multi-RTP configurations that require you to verify the actual RTP at your chosen casino. Players who want live roulette or blackjack alongside their slot sessions will need a casino that carries both Yggdrasil and a dedicated live provider. For everyone else, Yggdrasil’s combination of exclusive mechanics, certified fairness, and 275+ well-crafted slots makes it one of the stronger slot-focused providers available in 2026.
