Vikings Go Berzerk Guide: Rules, Rage Meters, Sticky Wilds and Treasure Chests

By the CasinoDemo editorial team · Updated 2026-11-09 · How we review

Vikings Go Berzerk is a Yggdrasil video slot on a 5x4 grid with 25 fixed paylines. Four Viking characters and four coins make up the paytable, but the real game is the Rage meter under each Viking and the sticky wilds they can turn into during free spins.

We loaded the official demo, read every rules page and played 25 base game spins at the default €2.50 bet. There is no bonus buy in this game, so everything below about free spins comes from the in-game rules, not from a feature we triggered.

How Vikings Go Berzerk works

The game has 5 reels, 4 rows and 25 paylines that pay from left to right. A win needs three or more identical symbols in sequence on a line, starting from the leftmost reel. Only the highest winning combination per line is paid, and line wins are added together. The number of lines is fixed; you change your stake through the coin value, and the bet is 1 coin per payline. The demo opened at a coin value of 0.10, which makes a €2.50 cash bet, with a €11,000 demo balance.

The wild substitutes for every symbol except Free Spin symbols, Treasure Chests and Golden Treasure Chests. The rules list the overall theoretical return to player as 96.1%.

Symbols and paytable

At a €2.50 bet the paytable shows these values. The four Vikings pay the most: the red-background warrior pays €25.00 for five (10x the bet), €10.00 for four and €3.00 for three. The purple-background Viking pays €20.00, €10.00 and €3.00. The green-background Viking pays €17.50, €7.50 and €2.50, and the blue-background shieldmaiden pays €15.00, €7.50 and €2.00.

The coins are the low pays. Gold pays €7.00 for five, silver €6.00, bronze €5.00 and the dark coin €4.00. Three coins pay €0.50 to €0.60. So a five-of-a-kind on the top Viking is 10x the bet on one line, and the base game leans on stacked Vikings and wilds to build bigger hits across several lines.

Rage meters and Berzerk mode

Every win with a Viking symbol in the base game adds Rage to that Viking's meter. The meter is a bar with 700 points as its maximum. A three-of-a-kind adds 4 points, four-of-a-kind adds 12 and five-of-a-kind adds 36. Fill one meter and you get 7 Free Spins with that Viking in Berzerk mode. No extra free spins bonus is selected for this trigger.

The Rage free spins are played at a coin value that is the average of the coin values used while collecting the points. The rules give the example of half the points at 0.2 and half at 2, which plays out at 1.1. That matters if you change your stake often: raising the bet right before a meter fills does not buy you a full-size bonus.

New players also get Welcome Rage: the first time you play, one Viking has its meter filled to more than 50%. Our demo opened with a "Free rage awarded!" message for exactly this.

Free Spin mode and the Siren

Three, four or five Free Spin symbols award 7, 14 or 21 Free Spins. All wilds are sticky for the whole session. When a Viking lands during free spins, it fights the Siren; if it wins, it turns into a sticky wild that stays until the feature ends. The fight happens before wins are paid for that spin. A Viking in Berzerk mode always beats the Siren, so every one of that character's landings becomes a sticky wild.

Free spins cannot be retriggered, and they are played at the bet that activated them.

Before free spins from scatters start, a randomizer picks one bonus: Ragnarök Free Spins (all Vikings are Berzerk), a Starting Wild (1 sticky wild in a random position), a Wild Reel (a sticky wild reel on a random reel), 1 to 3 extra Free Spins, or 5 extra Treasure Chests plus 5 Golden Treasure Chests added to the feature. Ragnarök is the one to hope for, because every Viking that lands sticks.

Treasure Chests and Golden Treasure Chests

The Treasure Chest lands only on reel 4 and holds 5 prizes; you pick one. In the base game it pays a coin win of 50, 75, 100, 125, 150, 200, 250, 500, 750 or 1,000 coins (the rules screen puts that at 2x to 40x your bet) or triggers 7, 14 or 21 Free Spins.

The Golden Treasure Chest lands only on reel 5. Its base game prizes are coin wins of 250 to 10,000 coins (10x to 400x your bet), a 7, 14 or 21 Free Spins trigger, a Rage Boost that adds 25% rage to each Viking, or a Ragnarök Free Spins trigger.

During free spins both chests switch to different prizes: coin wins, 2, 3 or 4 extra free spins, 1 or 2 extra sticky wilds, or a Wild Reel. The rules say the free spin prizes are much higher. If a chest lands on top of a sticky wild, both the chest and the wild are active that round.

What happened in our demo session

There is no bonus buy, so we spun the base game 25 times at €2.50. We saw scattered Free Spin symbols and wilds land, but never three scatters together, and no chest appeared. Small coin wins of €0.60 came up a few times. The best hit was €10.00, 4x the bet, from the blue shieldmaiden symbols stacking across the reels. After 25 spins the balance read €10,955.90, down from €11,000. That is one short session, not an average, and it tells you nothing about how often the bonus lands.

RTP, max win and volatility

The rules state a theoretical RTP of 96.1%. The rules pages we read do not list a maximum win or a volatility rating, so we will not quote one. The biggest fixed numbers on the screens are the Golden Treasure Chest's 10,000-coin prize (400x the bet) and the 10x line pay for five top Vikings, with sticky wilds in free spins as the route to anything larger.

Our verdict

Vikings Go Berzerk rewards patience more than most slots. The Rage meters give the base game a slow-burning goal, and a Berzerk or Ragnarök round, where every Viking turns into a sticky wild, is where the big potential sits. The catch is the averaged coin value on Rage spins and the lack of retriggers, so a weak bonus pick can end fast. We like it for the progress mechanic; just know the 96.1% RTP plays out over a long run, not 25 spins.
