Prepare for battle and sharpen your axe, and step into Thunderkick’s Bjorn, where a lone Viking warrior faces a horde of undead in a thrilling cluster-pays slot adventure. Positioned at the centre of the reels, Bjorn strikes down enemies, destroying symbols in his path to trigger cascades and generate instant cash prizes. As he clears the haunted woods, powerful upgrades unlock: better rewards, more enemies, and matching pathways. During the Bonus Game, all six abilities become persistent, letting you wield Bjorn’s ultimate power. Will you slay enough monsters to claim the heroic 5,000x max win? Join the fearless Viking today.
Bjorn Gameplay and Mechanics
Bjorn is a video slot from Thunderkick played on 8 reels and 8 rows. Wins use a cluster-pays system: land five or more matching symbols orthogonally adjacent to form a payout. The main Viking character acts as a Wild, while Draugr and Trolls appear as cash symbols, and hammers represent Scatters. Core features include Cascading, Hero Hunt, Abilities, Troll, Bonus Game, and Feature Buy. Cascades remove winning symbols and drop new ones, while Hero Hunt sends Bjorn through the reels, defeating enemies and collecting instant prizes. Upgrades enhance his path, spawn more foes, or convert symbols. During the Bonus Game, abilities become persistent, letting you stack all six for maximum power. Feature Buy offers instant access, chasing the 5,000x max win.
Bjorn Theme and Visuals
Bjorn plunges players into a dark Norse world where a lone Viking warrior stands against an undead horde. The reels are framed by a misty, moonlit forest, with runic stones and eerie green glows setting a haunting atmosphere. Thunderkick’s artwork is detailed and cinematic: Bjorn looks battle-hardened, while Draugr and Trolls are grotesque and menacing. Smooth animations bring his axe strikes to life, with symbols shattering and cascading dramatically. The soundtrack blends ominous drums, howling winds, and heroic, bold Nordic motifs. Together, visuals and audio create a truly immersive, action-packed Viking adventure that feels like a playable dark fantasy legend.

Bjorn Slot Features
Sharpen your axe and prepare for battle, brave Viking. Bjorn’s cluster-pays chaos, cascading wins, and undead foes await you now, so let’s look at the features that make the game potentially rewarding for all players.
Hero Hunt Feature
The Hero Hunt Feature is triggered when no winning clusters remain. The Hero Symbol hunts and defeats any Draugr symbols present on the game area, destroying symbols it passes over. The Hero Symbol then remains in place until it moves again or the game round ends. Defeated Draugr may drop Loot and award multipliers.
Abilities
- Increased Loot: Increased Loot chance and +1–2 multiplier per Draugr.
- Greater Loot: Greater Loot chance and +2–3 multiplier per Draugr.
- Adds 1 – 2: Adds 1 – 2 Draugr symbols.
- Adds 3 – 5: Adds 3 – 5 Draugr symbols.
- Hero path becomes Mystery symbols: Hero path becomes Mystery symbols.
- Mystery symbols may become Wild symbols: Mystery symbols may become Wild symbols.
Troll Feature
A special Troll symbol may appear before the spin sequence ends. The Troll destroys symbols in a 3×3 area as it moves, counts as 9 Draugr, and may award Loot and multipliers when defeated.
Global Multiplier
The Global Multiplier applies to all Cluster Wins and Loot Wins. It multiplies wins after the base win calculation and resets at the start of each new game round or Free Spin.
Bonus Game
The Bonus Game can trigger at the end of a spin sequence. Each Scatter has one chance to trigger the Bonus Game, and no fixed number of Scatters is required. When triggered, 5 Free Spins are awarded together with 1–3 random Abilities or upgrades. In the Bonus Game, every 20 defeated Draugr awards +2 Free Spins and 1–3 random Abilities or upgrades at the end of a Free Spin sequence. The Troll counts as 9 defeated Draugr toward this total. If all Abilities are at maximum level, only +2 Free Spins are awarded.
Wild Symbols
Wild symbols substitute for adjacent regular symbols horizontally or vertically, but not for Scatters or Draugr symbols. The Hero Symbol acts as a Wild only when present on the game area and not moving.
Cluster Pay
Cluster Pays occur when 5 or more identical symbols, except Scatters and Draugr symbols, connect horizontally or vertically. Winning symbols are removed and new symbols fall into place in an Avalanche. When the Hero Symbol is present on the game area, symbols fall toward it and may enter from different directions. The sequence continues as long as new wins occur or features are triggered.
Loot Wins
Loot Wins may be awarded from Loot dropped by defeated Draugr or the Troll. Loot is collected and paid according to the Loot Paytable when no further Avalanches or Draugr symbols remain. Pays are shown in € and are relative to the current bet (0.10, 0.20, 0.50, 5.00).
BET+ Options
A BET+ option may be activated at a cost that is a multiple of the current bet size. When activated, each spin guarantees the specified event until you deactivate it. All outcomes from BET+ activation pay according to the payable and in relation to the size of the base bet. BET+ functionality may not be available in all markets.

Final Verdict
