Vikings Go Berzerk connects base-game character wins to its Free Spins. Each Viking has a separate rage meter; filling one starts a bonus where that Viking defeats the Siren and becomes a Sticky Wild. Ragnarök can extend Berzerk Mode to all four.

Know this game
The useful information is character-specific: whose meter is building, which Viking is in Berzerk Mode, and which Wild positions remain for the rest of Free Spins.
Inside the game
The rage meters connect ordinary line wins to a character’s bonus behaviour.
The game uses five reels, four rows and 25 paylines running left to right. Three or more matching symbols in sequence on a payline form a win.
The ordinary paying set includes four Vikings and four Coin symbols. A Viking win has a second role: it contributes to that particular character’s rage meter.
Each of the four Vikings has a personal rage meter. A base-game win involving that Viking increases its meter.
Follow the character attached to the win, rather than adding all Viking wins to one shared progress bar. The individual meter determines which character gains Berzerk behaviour.
When a Viking’s meter fills, Free Spins begin with that Viking in Berzerk Mode. The enraged Viking always defeats the Siren and becomes a Sticky Wild for the rest of the feature.
The mode changes the relevant character’s interaction during the bonus. It does not automatically give every Viking the same state.
A Viking in Berzerk Mode always defeats the Siren. That guaranteed outcome is what makes its Sticky Wild conversion dependable once the mode is active.
The provider overview does not give a probability schedule for ordinary Viking-versus-Siren encounters. The guarantee described here belongs specifically to Berzerk Mode.
When Free Spins are triggered, a random Ragnarök upgrade can put all four Vikings into Berzerk Mode.
This changes the reach of the known feature: all four characters gain the Berzerk state rather than only the Viking whose meter filled. The upgrade is not promised on every entry.
A Golden Treasure Chest can appear on reel five. Yggdrasil describes it as awarding larger bonuses than the regular Treasure Chest.
The retained overview does not give a complete chest award table. Treat the Golden version as a distinct feature symbol, without assuming a fixed cash amount from its appearance.
Yggdrasil lists 96.1% RTP. That figure describes the provider’s documented configuration, not a measured return from a play session.
Check the rules in the opened game when comparing an operator’s version. The published figure alone does not identify every deployed configuration.
The provider classifies Vikings Go Berzerk as Medium–High volatility. That describes the design’s distribution of outcomes, not the result of a particular set of spins.
A visible rage meter explains feature progression; it does not establish an expected profit from continuing to play.
Yggdrasil lists 23 November 2016 as the release date. The game combines a conventional line format with persistent character progress.
Yggdrasil displays a €93,910 maximum-win figure, but the retained page does not establish the stake used for it.
Without that wager basis, the amount cannot be reliably converted into an “× bet” ceiling or compared directly with another game’s multiplier cap.
The saved official screen is a “Free rage awarded” introduction notice. It explains that filling any Viking’s meter starts Free Spins with that Viking in Berzerk Mode.
It is not a captured Free Spins result or a normal reel-spin screenshot. A fresh usable official session was not established in the latest bounded check.
Base-game wins build the meter of the Viking involved.
The ordinary meter trigger affects that character; the random Ragnarök state affects all four.
The converted Wild remains until the end of Free Spins. This does not establish persistence across separate sessions.
Vikings Go Berzerk is a good fit for players who prefer fixed paylines and visible character progress. The same Viking symbols connect the base game, meters and Sticky Wild bonus.
Its appeal depends on following those meters. Players wanting a variable-ways or cluster game, or a directly comparable bet-multiplier maximum, will find a different set of priorities here.

04 / The SlotsCollector take
Build each Viking’s rage meter, then turn that character into a persistent bonus Wild.
Vikings Go Berzerk makes its progression easy to associate with a character. A Viking wins, its meter grows, and its Berzerk state changes what happens against the Siren in Free Spins. The fixed 25-line format keeps that relationship readable.
Ragnarök expands the same idea to all four Vikings rather than introducing an unrelated bonus system. That continuity is the game’s strongest feature for players who like persistent progress.
The retained documentation has limits: it does not give a complete chest schedule or a wager basis for the displayed euro maximum. The character and Sticky Wild rules are clear enough to compare the game on its actual play structure.
