Bjorn Slot Review
A mountain ridge sits wrapped in mist under a bruised storm sky, black conifers ragged along its base, the edge of a gold-rimmed shield pushed half off the screen. Thunderkick’s Bjorn is the rare slot where the losing spins are the interesting ones: even when the clusters dry up, a Hero on the board means the round hasn’t finished with you yet.
It’s a Norse game that earns its darkness rather than borrowing it. An 8×8 cluster grid carries a 94.17% RTP, High volatility and a 5,000x max win, with the Hero Hunt at the centre of everything that happens.
Base Game & Features
Wins form through clusters rather than paylines. Any group of five or more matching symbols touching horizontally or vertically pays out. The winners are cleared, new symbols fall into place in an Avalanche, and the sequence keeps running while fresh wins or features appear.
Hero Hunt Feature
When no winning clusters remain, any Draugar symbols still on the board trigger the Hero Hunt. Bjorn hunts down and defeats the Draugar, destroying every symbol he passes over, then stays in place until he moves again or the round ends. Defeated Draugar may drop Loot or add to the multiplier.
Because symbols fall towards the Hero rather than always straight down, his position changes how the board refills. A losing-looking sequence often isn’t finished when the clusters stop.
Wilds and Mystery Symbols
Wilds substitute for adjacent regular symbols horizontally or vertically, but never for Scatters or Draugar. The Hero himself acts as a Wild while he’s on the board and not moving.
Odin’s Insight, one of the Abilities, turns the positions Bjorn passes over into Mystery symbols. These transform into random paying symbols, and at the second level they can become Wilds.
The Troll
A Troll can force its way onto the board before a sequence finishes, smashing everything in a 3×3 area as it advances. It counts as nine Draugar, so defeating it can drop substantial Loot and multiplier value. Those nine kills matter most in the Bonus Game, where the Draugar counter drives retriggers.
Abilities
Each game round awards Bjorn up to three of six available upgrades, chosen at random. They change enough from round to round that the icons are worth reading.
- Thor’s Strength – increases Loot drop chances and awards extra multipliers per defeated Draugar at Levels 1 and 2
- Call of Hel – adds Draugar symbols at the start of each spin or Free Spin, one or two at Level 1, three to five at Level 2
- Odin’s Insight – turns the Hero’s path into Mystery symbols, which may become Wilds at Level 2
Global Multiplier and Loot
The Global Multiplier applies to all Cluster Wins and Loot Wins alike, but it resets at the start of every new game round and every Free Spin. Only a single sequence that keeps extending, through Draugar kills, Hero Hunts and Avalanches, builds it into anything meaningful.
In practice most rounds nudged it up a little and ended before it grew teeth. Loot is the secondary reward, dropped by defeated Draugar and the Troll, collected and paid once no further Avalanches or Draugar remain. Values are relative to the current bet:
- 0.75x bet
- 1.50x bet
- 3.75x bet
- 37.50x bet
Bjorn Bonus Game & Free Spins
There’s no fixed Scatter count to hit. Every Scatter on the board gets its own single chance to fire the feature once the sequence resolves. A lone Scatter can convert, and you can never look at the grid and know you’re one away.
The gaps between natural bonuses didn’t stretch to the point of giving up on triggering one. The uncertainty over whether a Scatter would actually convert grated more than the waiting itself.
The Bonus Game awards five Free Spins together with one to three random Abilities or upgrades. From there, every 20 defeated Draugar grants two more Free Spins and another one to three Abilities, with the Troll counting as nine towards the total. If every Ability is already maxed, only the spins are awarded.
Five opening spins can vanish quickly if the Draugar don’t show up, and a bonus that never gets the engine moving feels over almost immediately. The one that builds is the one worth having.
In the best of them, a Troll landed close to the threshold, went down to the Hero, and the retrigger arrived with every mechanic visibly feeding the next.
BET+ Options
Four purchase routes are available, where the market allows them:
- Bonus Game – 150x bet, guarantees the Bonus Game, RTP 94.10%
- Bonus Boost Extreme – 12x bet, 20x more likely to trigger, RTP 94.19%
- Bonus Boost Plus – 3.5x bet, 5x more likely, RTP 94.21%
- Bonus Boost – 1.5x bet, 2x more likely, RTP 94.17%
Of the four, the 3.5x Boost Plus struck the best balance between cost and trigger frequency. The 150x direct buy is a one-off way to see the feature rather than a repeat route, and even then it doesn’t guarantee the bonus will build into one of the long Draugar chains.
Our Honest Verdict
Sitting through Bjorn feels less like spinning a slot and more like watching a series of small raids unfold over a dark mountain valley. That’s the one reason to pick it: a single round can catch fire and keep going when any other grid slot would have moved on.
When the bonus catches, it’s superb. Kills feed retriggers, retriggers feed upgrades, and a good run genuinely snowballs instead of just stretching out. The cost of that is everything in between. The multiplier dies with every round, the RTP is low, and long stretches produce clusters that lead nowhere.
This is one for players who like a game that resolves in stages and rewards patience with momentum. Anyone who wants a simple spin, or a visible count towards the bonus, will find it a slog. For the rest, the storm is worth weathering.
Bjorn FAQs
