Yggdrasil Slots | Free Slots by Yggdrasil

Founded in 2013 by former NetEnt executive Fredrik Elmqvist, Yggdrasil has grown from a Malta HQ into a global content publisher with studios and partners across Europe. The company licenses its content in multiple regulated markets (including Malta and Great Britain) and supplies games via its YG Masters program and GATI, its regulation-ready development toolkit that standardizes and speeds up worldwide distribution. 

On the tech side, Yggdrasil’s proprietary GEMs (Game Engagement Mechanics) power a large share of its catalogue. BOOST promotional tools enable network tournaments, prize drops, and missions across partner casinos.

Yggdrasil has repeatedly been recognized for innovation—most notably Innovator of the Year at the International Gaming Awards, with the 2023 win marking a seventh consecutive year of innovation recognition at the IGAs. The studio has also collected EGR B2B “Slot Provider of the Year” honors (including back-to-back wins in 2016 and 2017), cementing its status among top-tier slot suppliers.

Below are five of Yggdrasil’s most played, widely available titles. (RTPs may vary by jurisdiction; check the game info panel at your chosen casino.)

Other fan favorites you’ll encounter in many lobbies include progressive Joker Millions and the sequels and expansions in the Vikings and Valley series. 

• Themes: Vikings
• Format: 5 reels, four rows, 25 paylines
• RTP & Volatility: ~96.1% RTP; medium–high volatility

This fan-favorite sequel charges rage meters for each Viking during base play; fill one to trigger free spins where that Viking enters Berzerk Mode and turns wins into sticky wilds. Random chests and the chance of Ragnarök Free Spins keep the pace lively, making Vikings Go Berzerk one of Yggdrasil’s most replayed classics. 

• Themes: Ancient Egypt
• Format: Expanding grid with up to 3,125 ways to win
• RTP & Volatility: ~96.2%; high volatility

Every win awards a re-spin and removes blockers to expand the grid. Clear them all to unlock extra lives and win multipliers, creating that “one more spin” loop veteran players love. Valley of the Gods is an excellent example of Yggdrasil’s clean UX wrapped around fresh mechanics.

• Themes: Fishing, Underwater
• Format: 5×3, 20 lines with feature picks & free spins
• RTP & Volatility: ~96.8%; medium–high volatility

Hit the Pick-and-Click feature to add perks (extra wilds, stacked symbols, random wilds, and more) before free spins begin, tailoring each bonus round to your style. Mobile-friendly visuals plus meaningful choices make Golden Fish Tank one of Yggdrasil’s most approachable hits.

• Theme: Dinosaurs
• Format: 5 reels, 25 lines with cascading wins
• RTP & Volatility: ~96%; high volatility

A showcase for Yggdrasil’s DoubleMax mechanic: each consecutive cascade doubles the win multiplier with no stated limit, and an extra wild lands after every cascade. Raptor DoubleMax has one of Yggdrasil’s signature GEMs for explosive bonus potential. 

It’s a pure adrenaline slot that builds momentum fast—perfect for multiplier chasers.

• Theme: Steampunk
• Format: 5 reels, 20 lines
• RTP & Volatility: 96%; high volatility

Sticky wilds in free spins and wild transfers from the trigger spin can snowball into powerful setups. Cazino Zeppelin is a stylish, high-risk classic that laid the groundwork for later Yggdrasil “Cazino” titles.

Yggdrasil operates under B2B licenses, including the MGA Critical Supply Licence, and holds UK Gambling Commission approvals. The company supplies content certified in over 20 regulated markets, aligning with local compliance, testing, and safer-gambling objectives. The company publishes compliance guidance and embeds RG considerations alongside its platform tooling. 

While responsible gambling tools ultimately depend on the casino you use, top-tier regulators (e.g., the MGA and UKGC) require measures such as age verification, self-exclusion, time/limit controls, fair-play audits, and clear help links. Choose licensed sites and use free/demo modes to learn any slot before staking real money.
