Slot machine details and review Vikings go Berzerk
Vikings Go Berzerk is a fresh online slot from Yggdrasil that was released at the end of 2016. On its reels, 4 brave Vikings are waiting for you, ready to show their fury until you fill the reward meter. There are a lot of bonus features in the game and the whole experience is better than in the previous game Vikings Go Wild! It all takes place on a 5×4 playing field with 25 paylines. In addition, there are a lot of interesting points during the free spins and you will especially benefit from the Sticky Wild symbol.
Every slot machine must be manufactured by a company that invented, designed and put it into operation. Many players eventually find that they only enjoy playing on machines from specific manufacturers, so they narrow down their selection by preferred software manufacturers. In the Czech Republic, the most popular machines are from local software manufacturers such as Kajot or Synot.
What are the Cylinders or Reels on a slot machine?
Reels are the basic element of most slot machines and are columns of symbols that spin and stop on the screen gradually during the game. They are therefore the basic element on which symbols spin and on which winning combinations are formed. The most popular numbers of reels are 3 and 5.
Paylines on slot machines are imaginary lines that run through the reels of the machine and determine which combinations of symbols on these lines are considered winning. As the reels spin, players try to achieve winning combinations of symbols on these lines. Combinations must always start from the left. Each payline has its own payout value, and the winnings are determined by the paytable for each symbol on the particular machine. Modern slot machines can have hundreds of paylines, and players often have the option to choose how many of these lines they bet on.

Themes
Each slot machine has its own design or theme that appeals to a specific group of players. If you want to play slots with fruit symbols 🍉 or with an Egyptian theme 🐫, no problem. Just choose and we will narrow down the selection of slots to your taste.

What is RTP
The RTP of slot machines is a rule of thumb for how much money a slot machine will return to players. Let's say you put 100 crowns in it, the RTP determines how much of that money you should get back. The average value is 92 to 97%.

Slot theme and symbols
In any case, the features themselves are extremely engaging – the most fun rewards are the treasure chests. Each chest contains five random gifts, from which the player chooses one. The standard treasure chest appears on the fourth reel. It then has a more interesting little brother on the fifth reel in the form of a glowing treasure chest. It performs the same function, but the random gift is more profitable. The gift within the regular treasure chest includes 7 to 21 free spins or 50 to 1,000 coins. The golden treasure chest then contains five random gifts with 250 to 10,000 coins, 7 to 21 free spins, Ragnarok free spins and a rage boost.
After you top up the Viking Rage meter, you get seven bonus spins. There are four Vikings in the game, and each of them gains rage for winning. The winning Viking will be caught by the WILD symbol during the free spins, and it is in this mode that he is able to defeat the Siren. For overcoming the Siren, each Viking will become a fixed WILD symbol for the rest of the free spins. If you manage to fill the rage meter on multiple Vikings at once, you can get seven free spins for each Berserk. The exception to this rule is the Ragnarok free spins. These occur when all four Vikings enter berserk mode at the same time.

WILD Symbol
The game features special WILD symbols that can substitute for all other symbols except the bonus Scatter symbols and the bonus Treasure symbols, in order to create the best possible winning combination that matches the pay tables.
Treasure
The game features a Treasure Bonus symbol that appears on reel 4 and when it appears, it awards one of the following prizes:
Instant cash win (50-1000 credits). Activation of the free spins feature as well as bonus free spins (7-14 free spins).
The game features a Golden Treasure symbol that appears on reel 5 and, if it appears, will provide one of the following wins:
Activate the free spins bonus feature and award a bonus spin reward (7, 14 or 21 free spins)
Boost the Berzerk feature by adding 25% to each Viking’s Berzerk indicator
Activate the Ragnarok feature
During the active free spin feature, the treasure chests also contain other prizes such as: instant cash wins, bonus spins, 1-2 WILD symbols that are fixed in their positions and stacked WILD symbols, when WILD symbols appear in all positions.
Scatter symbol
The slot also allows you to play with Scatter symbols. If 3 Scatter symbols appear anywhere on the reels, 7 bonus spins are activated within one base game, 4 Scatter symbols trigger 14 bonus spins and 5 Scatter symbols trigger 21 bonus spins.
Free Spins
During the bonus spins, all WILD symbols that appear on the reels remain in their positions until the end of the bonus rounds. In case Viking symbols appear on the reel positions during the Free Spins mode, they can change to WILD symbol at will (Viking and Siren duel – if Viking wins, it will change to WILD) and the WILD symbol rule in the Free Spins mode will apply. Before the free spins are activated, one of the following features is randomly activated:
Ragnarok Free Turns
+ 1-3 additional spins
Starting WILD – the free spins feature mode starts with one WILD symbol
Stacked WILD – the WILD symbol appears in all reel positions
More Treasure symbols on the reels – 5 additional Treasure and Golden Treasure symbols
Berzerk Highlight
The game features a rage meter located below the game board. Each time a Viking symbol is part of a winning combination in the base game, the rage meter will fill up a little more. Better winning combinations will fill the meter more. If a Viking symbol fills the meter completely, the Viking will trigger bonus spins in Berzerk mode. If a Viking is in Berzerk mode while the Free Spins feature is active, he will win every time he fights the Siren and therefore will turn into a WILD symbol every time. A Viking can enter Berzerk mode if his rage meter is full or if the Ragnarok Free Spins feature is activated.
Ragnarok Free Spins
While Ragnarok Free Spins are active, all Vikings are in Berzerk mode. Ragnarok Free Spins can be activated as a win from a Golden Treasure symbol or as a random bonus for a recent Free Spins feature activation.
