Yggdrasil in 2026

Yggdrasil has declared 2026 its “year of innovation.” Two significant developments have already happened:

Game in a Box is Yggdrasil's new internal technology that compresses game development to under two months compared to the traditional 6-12 months. The first Game in a Box pilot studio, Slightly Edgy, signed in December 2025 and released its debut game Toothless Smile in March 2026.

GEM Lightning Lines is the newest addition to Yggdrasil's GEM mechanic family, launched in Q1 2026 the first entirely new GEM in several years.

Game selection

Yggdrasil is particularly known for its Vikings game series, which includes several popular games such as “Vikings Go Berzerk”, “Vikings Go Wild” and “Vikings Go to Hell”. Yggdrasil's game selection also includes other themes such as mythology (“Age of Asgard” , “Valley of the Gods”), joker-themed games (“The Dark Joker Rizes”, “Joker Millions”) and mystery games (“Blood Moon Wilds”, “Baron Samedi”). Their games are designed to work seamlessly across devices, thanks to the company's innovative iSense mobile app based on HTML5 technology. Thanks to this, players can enjoy Yggdrasil's games on computers, smartphones and tablets.

Vikings Go Berzerk

“Vikings Go Berzerk” is a popular video slot by Yggdrasil Gaming, which is a sequel to “Vikings Go Wild”. The game has 5 reels, 4 rows and 25 paylines oriented from left to right. The game's RTP (Return to Player) is 96.1%, and its volatility is medium to high, offering players reasonable winning opportunities and exciting gaming moments.

The game has several special features, such as Free Spins, during which the Viking characters can turn into Sticky Wilds. A particularly unique feature of the game is the dedicated Rage Meter for each Viking character, which fills up every time that character participates in a winning combination. When the meter is full, the player gets 7 free spins during which that viking is in “Berzerk” mode, always guaranteeing victory in battles with sirens and turning into a sticky wild until the end of the round.

During the game, there may also be treasure chests that can appear on the 4th or 5th reel and offer different prizes, such as coin wins or more free spins. Golden treasure chests have higher rewards than regular treasure chests.

Yggdrasil's product range also includes jackpot games such as “Joker Millions” and “Ozwin's Jackpots”, which are known for their progressive jackpots that can reach millions of euros. Yggdrasil's games can be found in many different online casinos, and their quality and excitement have played a key role in the company's success.

Yggdrasil's popular game mechanics

Doublemax™

Yggdrasil Gaming's DoubleMax™ is a game mechanic that offers players the opportunity to achieve significant winnings through repeated wins. This mechanic is used in several games of Yggdrasil, such as “Raptor DoubleMax™”, “Diamond Symphony DoubleMax™” and “Legend of Dragon Wins DoubleMax™”.

With the DoubleMax™ mechanic, every consecutive win in the game doubles the winning multiplier. This means that the multiplier increases exponentially with each successive win and is not capped. For example, in “Raptor DoubleMax™”, a game set in the time of the dinosaurs, players can see the winning multiplier increase after each winning combination. This feature increases the excitement and the chances of winning, as the winnings can increase significantly with consecutive wins.

GigaBlox™

GigaBlox™ is a game mechanic developed by Yggdrasil Gaming designed to produce big wins in casino games. This innovative feature brings huge symbols to the game, which can be 2×2, 3×3, 4×4 and even 6×6 grid sizes. The GigaBlox™ mechanic debuted in Yggdrasil's “Lucky Neko” slot and has since appeared in several other games such as “Giganimals GigaBlox™” and “Nightmares VS GigaBlox”.
