Vikings go Berzerk is a Video Slot with 5 reels, 4 rows and 25 paylines oriented from the left to right. The game has four Viking symbols and four Coin symbols that win if three or more are lined up in sequence on a payline.
Yggdrasil combined the best bits of the original game with some insane upgrades! Whenever you win in the base game with any of the Vikings, their personal rage meter rises. When the meter is full, the game goes into Free Spins mode where that particular Viking enters Berzerk Mode. This enables them to always defeat the siren and turn into a sticky wild until the end of the Free Spins.
Whenever you hit the Free Spins, you also get a random bonus: Ragnarök Free Spins which puts all 4 Vikings into Berzerk Mode. The Golden Treasure Chest can appear on the fifth reel and grants much bigger bonuses than the regular Treasure Chest!
