Yggdrasil was founded in Sweden in 2013 by a former NetEnt executive and remains one of the more design-forward mid-tier slot studios in the industry. The catalogue is anchored by Vikings Go Berzerk, Valley of the Gods and the Splitz mechanic family, which pioneered the split-symbol format now widely licensed to other studios.
Yggdrasil also operates YG Masters — a distribution programme that markets partner studios (Reflex, Peter & Sons, Bulletproof) under a shared certification and integration umbrella. This dual model gives the group a much larger effective catalogue than its in-house headcount would suggest.
Slot RTPs typically sit at 96.0-96.3% with medium-high volatility. Yggdrasil holds MGA, UKGC, Romanian and Ontario licences.
