Short answer: Yggdrasil is a Malta-licensed slot studio known for Vikings Go Berzerk, Valley of the Gods and the Raptor DoubleMax series. It holds a Malta Gaming Authority B2B licence (MGA/B2B/230/2012) and a UK Gambling Commission remote casino B2B licence, plus approvals in Gibraltar, Isle of Man and several European markets. Through Gambling Soft the games are already connected: you get them with the platform, without separate contracts or API keys, from $7,500.

Who Yggdrasil is

Yggdrasil calls itself an innovation-led iGaming studio. Besides its own slots it sells tools and platform services to other studios and operators. The company is led by CEO James Curwen and has two offices: Yggdrasil Gaming Ltd in San Giljan, Malta, and Yggdrasil Gaming Ltd in Krakow, Poland.

The studio works on three fronts, which it lists as people, products and platform. In practice that means three game lines on its site: YGG Games (in-house titles), Masters Games (partner studios that build on Yggdrasil technology) and Champions Games. Its awards page shows industry awards from 2015 to 2023.

RTP, volatility and mechanics

Yggdrasil does not publish one RTP for the whole catalogue. Its game filter lists RTP settings from 86% to 97% across titles, and volatility from low to super high. The exact RTP of each game and each configuration sits in the certification documents in Source, the studio's client zone. Check the version your casino receives before you advertise a number to players.

The studio builds its games on GEMs, Game Engagement Mechanics. The filter on yggdrasilgaming.com names Gigablox, MultiMax, Splitz, GigaRise, DoubleMax, DuoMax, Wild Fight, FastPot5, WildEnergy, TopHit, RushingWilds, BoltLock, OnlyWins, LightningLines and Lock 'em and Load 'em. Two examples from the technology page:

• DoubleMax: every consecutive win doubles the multiplier (x1, x2, x4, x8 and on), with no upper limit.
• BoltLock and DuoMax: two more GEMs named on the technology page.

For operators there is also BOOST, a promotion toolkit set up from the back office or via API: free spins, tournaments, missions and prize drops. For studios Yggdrasil sells Game in a Box, an all-in-one slot development platform, and Studio in a Box, a ready setup for launching a new studio.

Markets and licences

The footer of yggdrasilgaming.com links these licences (checked 28 October 2026):

The licences section of the About Us page adds approvals in Sweden, Romania, Greece, Belgium and the Buenos Aires City registry of suppliers. For a casino this matters in one way: a licensed supplier passes the regulator checks of most markets, so the games will not block your own licence application.
