The Vikings Go Berzerk slot is a Yggdrasil game from November 2016 with a 96.1% RTP, medium–high volatility and 25 paylines on five reels of four rows. Its hook is a rage meter for each of four Vikings: fill one and that Viking goes Berzerk in a round of free spins. Here’s how the meters, scatters and treasure chests fit together.
RTP is 96.1%, a 3.9% house edge, or about 3.9p per £1 staked on average.
Each Viking has his own rage meter, filled when he’s part of a win; a full meter triggers his Berzerk free spins.
Three, four or five scatters give 7, 14 or 21 free spins plus a random extra.
Our checked data has no max win figure, so check the help screen.

Vikings Go Berzerk slot: key facts
This Viking adventure from Yggdrasil followed Vikings Go Wild from 2015. It sticks with five reels, four rows and 25 fixed paylines, and adds a layer of progress tracking that the first game didn’t have.
There are three linked parts: the rage meters, the scatter-triggered free spins and the treasure chest pick feature. Each is described below in our own words.
Rage meters and Berzerk mode
Four Viking characters appear on the reels, and each has his own meter. Whenever a Viking forms part of a winning line, his meter fills a little. When one meter is full, that Viking goes into Berzerk mode and the game plays a round of free spins built around him.
Scatter free spins with a random extra
Three scatters award 7 free spins, four award 14 and five award 21. On top of the spins, the game adds one random bonus. Examples in the published description include Berzerk mode for all four Vikings at once, sticky wilds, or a wild reel.
Sticky Viking wilds
During free spins, Vikings can turn into sticky wilds. A sticky wild stays on its position for later spins in the round, so each one improves the odds of wins on the spins that follow.
Treasure chest pick feature
Treasure chests can land on reels 4 and 5. They open a pick feature where you choose items to reveal prizes such as coins, wilds or extra spins. The pick is part of the game’s design and doesn’t change the RTP based on what you click; the value is set by the maths, not by skill.
Rage meters and the RTP: what progress bars really mean
Meters that fill over time can feel like a reason to keep spinning. It’s worth being clear about what they do and don’t mean.
Rage meter myths and facts
Belief
Reality
A nearly full meter makes the next spin better value
Each spin is still random; the meter only records past wins and the RTP is the same overall
Stopping with a part-full meter wastes money
Money already staked is gone either way; the next spin costs the same 3.9% on average
Meters carry over to my next session
Check the help screen; our checked data doesn’t say whether progress is saved
Filling all four meters means a big win
Berzerk free spins vary widely, like any bonus round
The developer prices the Berzerk rounds into the 96.1% RTP. A meter close to full means a bonus is closer for that Viking, but it doesn’t make the game cheaper to play. Treat ‘one more spin to fill it’ thoughts as a cue to check your budget. The pull of the gambler’s fallacy is strongest with visible progress like this.

More scatters means three times as many spins at five as at three, and more spins mean more time for sticky wilds to build up. In a free spins round with sticky wilds, the later spins are usually the better ones, because more wild positions are locked in.
Vikings Go Berzerk RTP on a £20 budget
With a 96.1% RTP, the long-run cost is 3.9% of every pound staked. Medium–high volatility means the bonus features carry a good share of that value, so results swing a lot in short sessions.

The percentage cost is identical at every stake. The number of spins isn’t. Rage meters only fill as Vikings appear in wins, so a short session at £1 gives them very little chance to progress. A 10p stake gives the meters, scatters and chests far more spins to appear. Over an hour of steady play the turnover adds up: 500 spins at 10p is £50 staked, costing about £1.95 on average. Our page on cost per hour shows how to estimate this for any game.
Vikings Go Berzerk against the rest of the series
Yggdrasil has built a family of Viking games around the same characters. The table compares the three on our site using our checked data.
Go Berzerk sits between the two: livelier than the original, and the template for the Reloaded remake. If you like the theme but want something calmer, the first game’s lower volatility may suit you better. For more games in this setting, see our Norse slots page.

Frequently asked questions
What is the RTP of Vikings Go Berzerk?
Vikings Go Berzerk has an RTP of 96.1%, according to Yggdrasil’s published figures. That gives a house edge of 3.9%, so the average cost is about 3.9p per £1 staked over a very long run. Individual sessions vary widely, especially at medium–high volatility. Check the RTP shown in the game at your casino, and read our house edge explainer.
How do the rage meters work in Vikings Go Berzerk?
Each of the four Vikings has a meter that fills when he forms part of a winning line. When one meter is full, that Viking goes into Berzerk mode and you play a round of free spins. The meters record progress but don’t make the next spin better value; the RTP stays the same. Our gambler’s fallacy guide explains why that matters.
How many free spins can you get in Vikings Go Berzerk?
Three, four or five scatters award 7, 14 or 21 free spins, plus a random bonus such as Berzerk mode for all Vikings, sticky wilds or a wild reel. A full rage meter also triggers free spins for that Viking. During the spins, Vikings can turn into sticky wilds. Our free spins feature page explains how these rounds are built.
What is the max win on Vikings Go Berzerk?
Our checked data doesn’t list a maximum win for the original Vikings Go Berzerk, so check the game’s help screen at your casino. The 2021 remake, Vikings Go Berzerk Reloaded, lists a 25,000x cap. Max win figures are rare outcomes and say little about a typical session. Read our page on slot max wins.
What is the difference between Vikings Go Berzerk and Reloaded?
Reloaded is Yggdrasil’s 2021 update of the original. It keeps five reels, four rows and 25 paylines, lists a 96% RTP and a 25,000x max win. The original from November 2016 has a 96.1% RTP and medium–high volatility. Compare the full details in our Vikings Go Berzerk Reloaded review.
Can you buy the free spins in Vikings Go Berzerk?
Not in Britain. Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players. You reach free spins through scatters, a full rage meter or the random extras that come with scatter spins. Our feature buy rules page explains why the Commission raised concerns.
Is Vikings Go Berzerk a good slot for beginners?
It’s fairly easy to follow, but its medium–high volatility means results can swing a lot, which beginners may not expect. If you’re new, try the demo after age verification and start with a small stake so the budget lasts. The original Vikings Go Wild has lower volatility and may be a gentler start. Set a limit first.
