How We Review Slot Games

We test and rate all slot games across 5 criteria, assigning a score out of 10 for each and an overall score that is an average of the 5. To build an accurate assessment of each game we gather information from the supplier and play in real play or demo mode. Find out more.

Vikings Go Berzerk is a 2016 slot release from Yggdrasil, and one of five games in the Vikings series from this developer. It is a 5 reel game with 25 paylines and a medium-high variance. It has an array of fun features, including instant win Treasure Chests and Wilds in the base game. The objective though is to reach the free spins round where every Viking that lands on the reels battles with a Siren. If they win, then their position turns into a Sticky Wild for the round. For added fun, filling Viking Rage Meters turns them into Berzerkers where they are guaranteed to win every battle.

This popular slot has a maximum win of 4,000x and spins start at 25p.

Testing Notes: Here’s What Happened When We Played Vikings Go Berzerk

IMPORTANT: To give you an accurate assessment of the games we review our writers play 200 spins. Whilst this is a useful tool to help us review games and to give an example of what might happen when you play, keep in mind that 200 spins is only a very small sample and cannot be used to accurately predict what might happen over another 200 spins. The outcome of all slots play is always random.

Boom Or Bust? Our Session By The Numbers

I played 200 spins on Vikings Go Berzerk for free at Casumo Casino to test the game and this is what happened.

  • Stake Size: £1
  • Start balance: £11,000
  • End balance: £10,980.68
  • Biggest Win: 26.92x
  • Free Spins Round: 1
  • Session Time: 22 minutes 53 seconds

There was certainly no shortage of action over my 200 spins. Wins came up on every 4 to 5 spins and I counted 8 Treasure Chests on reel 4 (4% of spins), though not a single Golden Treasure Chest. Every Treasure Chest produced an instant win rather than a free spins round. That isn’t surprising as the Free Spins are not supposed to be easy to unlock.

I triggered the free spins round once (fairly typical for a mid-high variance slot) through 3 scatters to get 7 spins. The modifier I was given was extra Treasure Chests. By the end of the round I had SIX sticky wilds in place thanks to Viking vs Siren battles.

What We Liked

  • Brilliant progressive gameplay through Viking Rage Meters
  • Chance to land lots of Sticky Wilds for your free spins
  • Treasure Chests appeared regularly in testing
  • Random extra modifiers with every free spins round
  • Less volatile than other Vikings slots from Yggdrasil

What We Didn't like

  • 25p minimum bet is quite high
  • 4,000x max win is underwhelming

What Our Reviewer Says ...

Overall Score: 8.2

Theme & Design

Our Score 9

A Little Dated But Still An Epic Slot By And Standards

Vikings Go Berzerk starts with a super-cool 3-d video of a Viking battle with the Sirens amidst a shipwreck on the rocks. It’s a dramatic opening suitable for an epic game. Once the game starts for real then the action plays out on a grandiose longship riding the waves, your 5 reels and 4 rows of symbols set against the backdrop of the ship’s sale. It looks a bit dated now, but thanks to the orchestral score and the compelling gameplay, that doesn’t matter too much. And in fact, the visuals get better when the bonus round kicks in and the sky darkens for battles between Viking and Siren.

RTP and Variance

Our Score 8

What is RTP?

RTP (Return to Player) refers to the amount a game will pay out in cash prizes expressed as a percentage of all the money wagered on that game. For example, a 96% RTP means a game will pay out £96 for every £100 wagered. This is an average number and will vary from one session to the next.  Read more here.

What is Variance?

Variance refers to how far a game will deviate from its RTP over time. High variance games deviate a lot and produce uneven win distributions and unexpected windfalls. Low variance games provide a more stable and even distribution of wins. Read more here.

Vikings Go Berzerk has a good RTP of 96.1%. This is also a medium-high variance slot, so not as volatile as the other ‘vikings’ slots that came after it from the same studio. As testing showed, the win distribution is more even and features drop fairly regularly.

Maximum Win

Our Score 7

What Is Maximum Win?

Maximum win refers to the maximum amount a player can win from one spin. It is expressed as a multiple of the stake. For example, where the maximum win is 100,000x, from a £1 stake, the maximum win would be £100,000.  

The top payout from Vikings Go Berzerk is 4,000x. That isn’t bad for a mid-variance game. If you want better potential from a similar type of slot then you could try the Reloaded version with a 25,000x max win, but you’ll have to ride out a much higher volatility.

Symbols and Paytable

Our Score 8

This is a standard 5-reel slot with 4 rows and 25 paylines. You’ll need to land 3 or more identical symbols from left to right along a payline, starting on the left most reel, to trigger a win.

Vikings Go Berzerk Paytable
The Paytable

There are 8 symbols on the paytable. The 4 low payers are the coins, iron, bronze, silver and gold. These are valued at from 0.2x for 3 iron coins up to 2.8x for 5 gold coins. The premiums are the 4 Vikings, valued at from 0.8x for 3 women Vikings up to 10x for 5 of the top premium Vikings.

There is also a Wild symbol that will substitute in for any other pay symbol to complete a payline.

Features and Gameplay

Our Score 9

Vikings Go Berzerk has an interesting collection of features with Rage Meters, Treasure Chests and Free Spins rounds with all kinds of modifiers.

Here is how it all works:

Viking Rage Meters Unlocks Free Spins Round

The first thing to note is that each of the four Vikings has a Rage Meter displayed at the bottom of the reels. Each time you score a win with a Viking symbol on it, their respective meter will charge further. As a head start, one Viking will have their meter half-charged at the start of the game.

Fully charging a Viking meter will trigger the free spins round with 7 spins where the respective Viking is ‘Berzerk’ for the full round.

What is a Berzerk Viking? During Free Spins, when a Viking lands on the reels it goes into battle with a Siren. If it wins, the position it sits in converts to a sticky wild. The outcome of the battle is random BUT a Berzerk Viking will ALWAYS win.

So, playing Free Spins with a Berzerk Viking is good because it allows you to fill more of the reels with Sticky Wilds which help trigger more wins.

More on the free spins round in a moment.

Treasure Chests With Instant Prizes or Free Spins

There are two types of Treasure Chest that appear in both the base game and free spins round to reveal prizes, modifiers, or a fast-track to the free spins round.

Regular Treasure Chests

These appear on reel 4. When they do, five cards are shown on the screen and you must pick one to reveal a prize.

Instant Win Prizes from Treasure Chest Feature
The Treasure Chest feature in Vikings Go Berzerk

During the base game, the regular chest will award an instant win prize of between 2x and 40x or between 7 and 21 Free Spins.

During the Free Spins round, regular chests can award 2x to 40x stake, 2 to 4 additional Free Spins, a Sticky Wild reel or 2 additional Sticky Wilds.

Golden Treasure Chests

These appear on reel 5. Again, 5 cards are shown and you must pick to decide which prize you get.

In the base game the golden chest can award an instant win prize of between 10x and 400x stake, or between 7 and 21 Free Spins, Ragnarok Free Spins or a 25% Rage Boost for your Vikings.

Then, during free spins they can award instant prizes of between 10x and 400x stake, or 2, 3 or 4 extra Free Spins, a Sticky Wild Reel or 2 extra Wilds onto the reels.

Free Spins With Wild Reels, Sticky Wilds and Extra Treasure Chests

The free spins round is even more action-packed.

There are THREE ways to trigger it:

  • Land 3, 4 or 5 scatters to get you 7, 14 or 21 spins.
  • A lucky pick through the Treasure Chests for 7, 14 or 21 spins
  • Fill a Viking Rage Meter to trigger 7 spins with your respective Viking in Berzerk mode!

Before your Free Spins play out, a modifier is randomly chosen for the round:

  • Wild Reel – one reel randomly turns entirely wild
  • Starting Wild – 1 Sticky Wild appears on the reels
  • Free Spins – 1, 2 or 3 extra Free Spins are awarded
  • Ragnarok Free Spins – All Viking symbols go Bezerk
  • Extra Treasure Chests – 5 extra treasure chests are added to the reels

The key to the free spins round is this:

During free spins, ALL wilds that land become sticky. And, when a Viking symbol lands, then it enters into a battler with a Siren. The outcome is random (unless the Viking is in Berzek mode) but if they win, then their position turns into another Sticky Wild.

Essentially, you have the chance to fill the screen with many Sticky Wilds to boost your win potential here.

Ragnarök Free Spins Round With ALL Vikings In Berzerk Mode

The holy grail of Vikings Go Berzerk is this, the Ragnarök Free Spins round. You can only access this via a lucky pick on the Golden Treasure Chest feature OR through the random modifier chosen at the start of the standard free spins round.

In this feature, ALL Vikings are in Berzerk mode, so whenever they land their position turns into a Sticky Wild.

This notoriously elusive feature will take more than 8,000 spins to unlock on average!!

The Final Verdict

Vikings Go Berzerk looks a bit dated now but it is an evergreen slot thanks to its compelling mix of features and relatively-balanced pay model. I say relatively because this is still on the higher side of mid variance so it can still be a tight play at times! Whilst the Treasure Chests are a neat feature, Vikings Go Berzerk is really all about that free spins round where adding more and more Sticky Wilds to the reels can really boost your wins. Meanwhile, the Rage Meters that were innovative at the time back in 2016 still give the game added thrills even now. Perhaps the only downside to Go Berzerk is the 4,000x max win that is underwhelming in today’s world of slots, and that 25p min bet that might price out some players.

Useful Tips When Playing Vikings Go Berzerk

Remember, online slots are games of chance, there is NO strategy that can improve your odds of winning. However, reading our review and following these tips will help you get the most out of your time playing this slot game.

1. Fill The Rage Meters

If you can fill one of the Rage Meters your chances of scoring big wins in the free spins round increases because your Berzerk Viking will always win their battles. So, keep your eyes on the rage meters at the foot of the reels.

2. Choose A Sensible Stake To Start

For mid-high variance games like this that can be volatile I recommend starting at a low-ish stake to stretch your balance and give yourself a chance of triggering one of the free spins round before you zero out!

 

3. Play With A Slots Bonus

Most of the deposit match bonuses advertised on our site are eligible for Yggdrasil games. For example, you can get a 100% match up to £300 at Grand Ivy to play Vikings Go Berzerk. That’s a lot of extra spins on the house!
