Yggdrasil Slots | Free Slots by Yggdrasil

Founded in 2013 by former NetEnt executive Fredrik Elmqvist, Yggdrasil licenses its content in multiple regulated markets and supplies games via its YG Masters program and GATI, its regulation-ready development toolkit that standardizes and speeds up worldwide distribution. 

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

Yggdrasil has consistently been recognized for its innovative slot gaming. Its industry awards include:

• Software Rising Star at the 2015 EGR B2B Awards

Below are some of Yggdrasil’s most played, widely available slots.

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 slots. 

• 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: 5x3 grid; 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 slots.

• 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” slots.

Yggdrasil operates under B2B licenses. 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 require measures such as age verification, self-exclusion, time/limit controls, fair-play audits, and clear help links. You should always choose licensed sites and use free demo modes to learn any slot before staking real money.
