Vikings Go Berzerk Demo & review
A 25-line Viking slot where base-game wins fill four rage meters, and free spins turn every Viking that beats the Siren into a sticky wild.

8.6/10
Yes, if you play for free spins that build. Every Viking that lands in the round fights the Siren, the winners stay as sticky wilds, and the bonus drawn before the first spin can change everything, up to Ragnarok with all four Berzerk. The drawback is the wait: the rage meters fill slowly, nothing can be bought, and between rounds the line wins are small.
Who it suits
Play this if…
- Bonus chasers: every Viking that wins its fight stays as a sticky wild to the end of the round
- Series fans: this is Vikings Go Wild with rage meters and a bonus drawn before each round
- You like a slow goal between features: four meters build across a session, even on small line wins
Skip this if…
- Bonus buyers: nothing can be bought, so every round has to arrive by itself
- Short-session players: a full meter takes hundreds of points, and line wins between rounds are small
- Players who want Ragnarok on demand: it comes only from the draw before free spins or a Golden Treasure Chest

Vikings Go Berzerk: Full Review
Every Viking line win in this Yggdrasil slot feeds that Viking's own rage meter, and a full meter starts free spins where he cannot lose his fight. Vikings Go Berzerk arrived in November 2016, the year after Vikings Go Wild, and keeps that game's best idea: Vikings that win a fight stay on the reels as sticky wilds. It suits bonus chasers who want something building between rounds rather than a bonus to buy.

How Vikings Go Berzerk works
Twenty-five fixed lines pay left to right across five reels of four rows, for three or more in sequence from the leftmost reel. The WILD stands in for everything except Free Spin symbols and the two chests. Four Vikings top the paytable and four coins sit below them, and the pays are printed in coins, with 25 coins to one bet.
| Viking pays at $1 | Five | Four | Three |
|---|---|---|---|
| Red-bandana Viking | $10.00 | $4.00 | $1.20 |
| Eye-patch Viking | $8.00 | $4.00 | $1.20 |
| Skull-hat Viking | $7.00 | $3.00 | $1.00 |

The 5x4 reels before our first spin, with a rage meter under each Viking portrait. FluxPlays demo test, 9 November 2026.
What feeds what:
- Base-game wins on a Viking add rage to that Viking, and a full meter starts 7 free spins with him Berzerk.
- Three or more Free Spin symbols start the main free spins, with one bonus drawn first.
- In free spins, any Viking that lands fights the Siren, and winners become sticky wilds.
- A Treasure Chest on reel 4 and a Golden Treasure Chest on reel 5 each offer a pick of five prizes.
Free spins are the heart of this game, and the bonus drawn before them decides how far a round can go. The chests are the side dish.
How the rage meters work
Each Viking has his own bar of 700 points, and only base-game wins on that Viking fill it: 4 points for three of a kind, 12 for four and 36 for five. Filling one awards 7 free spins with that Viking Berzerk, and no extra bonus is drawn. By the rules it takes at least 20 five-of-a-kind wins on one Viking, so the meters are a slow goal. The one shortcut is a Rage Boost from the Golden Treasure Chest, which adds 25% to every Viking.
On your first play one Viking starts more than half full. The round a full meter gives is played at the average coin value you used while collecting the rage, so raising the stake just before a meter fills changes little.

Vikings Go Berzerk free spins: how they trigger
Three Free Spin symbols start 7 free spins, four start 14 and five start 21, always at the bet that triggered them. The symbols cannot retrigger the round, so only a chest can add spins. Every wild in the round is sticky until it ends, and each Viking that lands fights the Siren before the spin pays. A winner turns into a sticky wild and a loser stays a Viking. The rules give no odds for the fight.
A Berzerk Viking always wins it, which is why a filled meter or a Ragnarok draw matters so much.
The bonus drawn before the first spin
| Bonus | What it does |
|---|---|
| Ragnarok Free Spins | All four Vikings are Berzerk, so every Viking that lands beats the Siren |
| +1 to 3 Free Spins | Extra spins on top of the award |
| Starting Wild | One sticky wild in a random position |
| Wild Reel | A sticky wild reel on a random reel |
| Extra Chests | 5 more Treasure Chests and 5 more Golden Treasure Chests in the round |
Rage-meter rounds get no draw. Ragnarok is the one that changes the shape of a round, and a Golden Treasure Chest in the base game can award it directly.

The two chests
Each chest holds five prizes and you choose one.
| Chest | Lands on | Base game | Free spins |
|---|---|---|---|
| Treasure Chest | Reel 4 | 2x to 40x the bet, or 7 to 21 free spins | 2x to 40x, 2 to 4 extra spins, Wild Reel, or 1 or 2 extra wilds |
| Golden Treasure Chest | Reel 5 | 10x to 400x, 7 to 21 free spins, Ragnarok Free Spins, or Rage Boost | 10x to 400x, 2 to 4 extra spins, Wild Reel, or 2 extra wilds |
RTP, volatility and max win
By the rules the RTP is 96.1%, and Yggdrasil's game page gives the same figure. The Medium-High volatility label comes from that page too, because the rules carry none. The game names no top win: the rules and paytable are silent and the provider's page gives only a cash amount. Review sites print everything from a flat cash sum to a multiple of the bet, so we leave the max win out rather than pick one.

natural triggers in the session
Played on Yggdrasil's public demo (game 10147, rules version 2.71) on 9 November 2026, in US dollars from an $11,000.00 demo balance, in one session with no reload. All 100 spins were at $1.00 (coin value 0.04 x 25 lines). The game has no bonus buy, ante, gamble or paid mode. Scatter free spins came on spins 13, 14 and 100, 7 spins each; base-game Treasure Chests on spins 71 and 72 paid 50 and 75 coins. Closing balance $11,119.48 on the server and on screen.
The bonus handed out before each round decided how it felt. Spin 14 drew Ragnarok, and by the end of the round the board was mostly wild. The best free spin paid $39.36, and the round came to $108.00.

Spin 14 settled: $108.00 from the Ragnarok round. FluxPlays demo test, 9 November 2026.
Spin 13 drew Extra Chests just before it. A chest on its third free spin paid $15.60, the biggest step of a $38.00 round. Starting Wild on spin 100 was milder at $25.64.
Spin 13 mid-round: sticky wilds piling up on the first three reels, one free spin left after this one. FluxPlays demo test, 9 November 2026.
The 97 spins around those rounds came to $47.84, one stretch ran 20 spins without a win, and the base-game chests that landed on spins 71 and 72 paid 50 and 75 coins. No meter filled, even with one Viking handed 490 of 700 rage from the start, and the Golden Treasure Chest, Wild Reel and the extra-spins bonus stayed away, so those are described from the rules. A hundred spins can show how the rounds behave, but nothing about what the game returns.
Is Vikings Go Berzerk worth playing?
For a bonus chaser, yes. For someone who wants action every few spins, less so. The draw before free spins gives each round its own character, and the rage meters give the base game a reason to exist. Against that, a meter takes a very long time to fill, and you wait for every round.
Pick Vikings Go Wild for the series at its simplest, with longer free spins awards and a calmer Low to Medium label. Pick Vikings Go Berzerk for rage meters, the bonus draw and the Ragnarok round we would actually play this game for.
In the demo, watch the Viking who starts more than half full: his meter shows you how far one five-of-a-kind actually moves the bar.
Frequently Asked Questions
How do you trigger free spins in Vikings Go Berzerk?+
Land three, four or five Free Spin symbols for 7, 14 or 21 free spins, plus one bonus drawn before the round. A full rage meter starts a separate round of 7 with that Viking Berzerk and no extra bonus, and a chest in the base game can hold free spins too.
What do the rage meters do in Vikings Go Berzerk?+
Each Viking has a meter that only his own base-game wins can fill, at 4, 12 or 36 points for three, four or five of a kind. At 700 points he awards 7 free spins in Berzerk mode, played at the average coin value you used while collecting the rage.
What are Ragnarok Free Spins?+
A free spins round where all four Vikings are Berzerk, so every Viking that lands beats the Siren and becomes a sticky wild. It comes from the bonus draw before scatter free spins or from a Golden Treasure Chest in the base game. It was the best round of our session.
What is the max win in Vikings Go Berzerk?+
The game does not state one. Neither the rules nor the paytable give a cap, and Yggdrasil's page names only a cash amount, which depends on the stake. The largest figure the game itself prints is a Golden Treasure Chest prize of up to 400x the bet.
